Description:
BACKGROUND OF THE INVENTION 
       [0001]    1. Field of the Invention 
         [0002]    The present invention generally relates to an electrical connector, an electronic apparatus using the same, and an assembling method of the electrical connector; particularly, the present invention relates to a terminal structure of an electrical connector having better contact elasticity. 
         [0003]    2. Description of the Related Art 
         [0004]    Presently, the development of signal transmission standards of Universal Serial Bus (USB) has reached USB version (3.0). Electrical connectors in compliance with USB 3.0 standards not only can selectively electrically connect a USB 3.0 complementary electrical connector, but may also selectively electrically connect electrical connectors in compliance with USB 1.0/2.0 standards so that signal transmissions complying with the USB 1.0/2.0 standards may be conducted. In order to allow the USB 3.0 electrical connector to be compatible with USB 1.0/2.0 standards, the USB 3.0 electrical connector has a structure with a plurality of terminal sets. For instance, there may be at least a set of terminals for transmitting USB 1.0/2.0 signals, and a set of terminals for transmitting USB 3.0 signals. 
         [0005]    Some examples of conventional USB 3.0 electrical connectors, such as Taiwan patent M346198, M346941, M348358, M357776, M366783, M370859, M376015, M405081, 200945689, 201125228, 201112540, and U.S. Pat. No. 7,972,151, U.S. Pat. No. 7,927,145, and U.S. Pat. No. 7,833,065, are primarily featured with a plurality of structures of terminals, an insulation body for carrying the structures of terminals, and a metallic shielding casing to house the insulation body. Due to the fact that the insulation body includes a plurality of discrete plastic elements, each discrete element needs to be manufactured individually and then assembled together in order to secure the aforementioned structures of terminals in the different layers within the assembled insulation body. However, this type of complicated and small-dimensional structure would not only require the use of many different molds to manufacture, the assembly tolerance and the difficulties involved in the assembling process would also be increased and cause the product yield to be decreased, which results in higher manufacturing costs. In addition, each USB 3.0 terminal of the mentioned structure of plurality of terminal sets includes a contact section whose surface evenly contact or is fixed on a wall surface of a corresponding passage on the insulation body so that there is no elasticity for mating. In this manner, when corresponding terminals of a complementary electrical connector is inserted into the conventional USB 3.0 electrical connectors to press against another corresponding surface of those contact sections, since the terminals lack any elasticity for buffering purposes, the structure of the USB 3.0 terminals is likely to be damaged by the direct strike during mating. 
         [0006]    In other conventional USB 3.0 electrical connectors, such as Taiwan Patents M329880, M329877, M359066, M366792, M379191, 200910693, and U.S. Pat. No. 7,517,253, U.S. Pat. No. 7,625,243, U.S. Pat. No. 7,641,519, U.S. Pat. No. 7,736,184, U.S. Pat. No. 7,806,704, U.S. Pat. No. 7,806,735, U.S. Pat. No. 7,833,065, U.S. Pat. No. 7,837,510, U.S. Pat. No. 7,862,346, U.S. Pat. No. 8,002,589, U.S. Pat. No. 8,052,477, US2010/0322566, and US2011/0143599, although the complicated structure of the insulation body has been simplified slightly, the contact sections of the USB 3.0 terminals of the insulation body similarly includes a surface evenly contact or is fixed to a wall surface of a corresponding passage on the insulation body. When the corresponding terminals of the complementary electrical connector is inserted into the USB 3.0 electrical connector to electrically contact another corresponding surface of these contact sections, the structure of the USB 3.0 terminals is similarly likely to be damaged by the direct strike. 
       SUMMARY OF THE INVENTION 
       [0007]    In order to solve the above problem of the prior art, it is an object of the present invention to provide an electrical connector featured with a terminal structure comprising an elastic contact section and at least one elastic/non-elastic support section. When the corresponding terminals of a complementary electrical connector electrically contacts the elastic contact section, the at least one elastic/non-elastic support section may provide better contact elasticity so that damaging the terminal structure may be prevented. 
         [0008]    In order to achieve the above objectives, a preferred embodiment of the present invention provides an electrical connector for use in electrically connecting with a complementary electrical connector. The structure of the electronic connector includes a first terminal set, a second terminal set, an insulation body, and a positioning part. 
         [0009]    The first terminal set includes a pair of first differential signal terminals and a pair of second differential signal terminals. The second terminal set includes a pair of third differential signal terminals. Each terminal of the first terminal set and the second terminal set has an elastic contact section, at least one elastic support section, at least one holding section, and a soldering pin section. For the first terminal set, two opposing sides of the elastic contact section respectively extend outward to form at least one wing section. For the first terminal set, the at least one elastic support section is connected to the elastic contact section, wherein at least a bend is formed at the connection point with the elastic contact section. 
         [0010]    The insulation body has a base part and a mating part that extends outward from the base part to an end. A mating surface is formed on the mating part to correspond to the connection of the complementary connector. The insulation body comprises a plurality of first terminal set passages and a plurality of second terminal set passages to be respectively configured with the first terminal set and the second terminal set. The first terminal set passage and the second terminal set passage extend to the base part and mating part of the insulation body, wherein the first terminal set passage extends and passes through an end of the mating part, and at least one blocker is formed in at least one inner side wall of the first terminal set passage to correspond to at least one wing section of the first terminal set. 
         [0011]    When the first terminal set and the second terminal set are respectively configured in the first terminal set passage and the second terminal set passage, at least one holding section of the first terminal set and the second terminal set separately fixes the first terminal set and the second terminal set in the first terminal set passage and the second terminal set passage of the insulation body. At least one elastic support section of the first terminal set is located in the first terminal set passage, and the elastic contact section of the first terminal set and the elastic contact section of the second terminal set is distributed on the mating surface of the mating part, wherein the distribution position of the elastic contact section of the first terminal set is closer to the end of the mating part than the distribution position of the elastic contact section of the second terminal set. 
         [0012]    When the elastic contact section of the first terminal set of the electrical connector contacts the complimentary connector, at least one elastic support section of the first terminal set provides flexibility the elastic contact section of the first terminal set requires for the elastic contact section of the first terminal set to elastically move within the first terminal set passage. However, at least one blocker of the first terminal set passage will block the movement of the at least one wing section of the elastic contact section of the first terminal set, limiting the elastic movement distance of the elastic contact section of the first terminal set in the up or down directions. In the present embodiment, the at least one blocker of the first terminal set passage includes an upper blocker and a lower blocker. The upper blocker is used for blocking the movement of the at least one wing section within the first terminal set passage in the upward direction, limiting the upward elastic movement distance of the elastic contact section of the first terminal set. The lower blocker is used for blocking downward movement of the at least one wing section to limit the downward elastic movement distance of the elastic contact section of the first terminal set. 
         [0013]    The positioning part is disposed on the base part of the insulation body, and the soldering pin section of the first terminal set and the soldering pin section of the second terminal set extend outward of the base part of the insulation body and pass through the positioning part. 
         [0014]    According to another preferred embodiment of the electrical connector, the first terminal set further includes an elastic slice section which is a bend starting from the elastic contact section and extending towards the mating surface of the insulation body. The elastic slice section is used for contacting the complementary electrical connector. 
         [0015]    According to another embodiment of the electrical connector, at least one bend of the first terminal set is exposed out of the end of the mating part of the insulation body. 
         [0016]    According to yet another embodiment of the electrical connector, the at least one elastic support section of the first terminal set includes a first elastic support section and a second elastic support section. The second elastic support section is pre-compressed and connecting against a sidewall in the first terminal set passage. The at least one bend includes a first bend and a second bend, wherein the first bend is formed on the connection between the first elastic support section and the elastic contact section, and the second bend is formed on the connection between the second elastic support section and the elastic support section. 
         [0017]    According to another embodiment of the electrical connector, each terminal of the first terminal set has an elastic contact section and at least one support section. A portion of the at least one support section is fixed within the first terminal set passage, wherein at least one bend is formed in the connection between the elastic contact section of the first terminal set and the at least one support section. In this manner, the elastic contact section of the first terminal set elastically moves within the first terminal set passage, using the connection between the elastic contact section and the at least one support section as a fulcrum. The two opposing sides of each elastic contact section of the first terminal set separately extend outward to form at least one wing section, and at least one blocker is formed in at least one inner sidewall of each first terminal set passage of the insulation body to correspond to the at least one wing section. When the first terminal set is accommodated in the corresponding first terminal set passage, at least one blocker of the first terminal set passage is used for limiting the movement of the at least one wing section of the first terminal set in a vertical direction such that the upward or downward elastic movement distance of the elastic contact section of the first terminal set is restricted, wherein the at least one blocker may also be used to limit movement of at least one support section of the first terminal set in a horizontal direction. 
         [0018]    According to another embodiment of the electrical connector, the first terminal set having at least one support section includes an elastic slice section that is a bend formed in the elastic contact section and extends toward the mating surface. The elastic slice section is used for contacting a complementary electrical connector. 
         [0019]    According to another embodiment of the present invention, an electronic device is provided that includes the various above mentioned embodiments of the electrical connector. 
         [0020]    In addition, according to another embodiment, an assembling method of the electronic connector is provided and includes the following steps: 
         [0021]    The first terminal set is loaded into the plurality of first terminal set passages from a first end of the insulation body, wherein the insulation body has a base part and a mating part, the mating part extends outward from the base part to the first end and the mating part comprises a mating surface, and the first terminal set passage has a pair of first differential signal terminals and a pair of second differential signal terminals. 
         [0022]    A second terminal set is loaded into a plurality of second terminal set passages of the insulation body. The second terminal set has a pair of third differential signal terminals, wherein each terminal of the first terminal set and the second terminal set has an elastic contact section and at least one support section that is connected to the elastic contact section, and the elastic contact section of the first terminal set is distributed on the mating surface of the mating part. At least one support section of the first terminal set comprises at least one elastic support section. The at least one elastic support section is an elastic arm structure, wherein a portion of the elastic support section is connected against the wall surface of the first terminal set passage to provide elasticity such that the elastic contact section of the first terminal set may elastically move within the first terminal set passage. The elastic contact section of the second terminal set is distributed on the mating surface of the mating part, and the distribution position of the elastic contact section of the first terminal set is closer to the first end of the mating part than the distribution position of the elastic contact section of the second terminal set. 
         [0023]    According to another embodiment of the assembling method of the electrical connector, the assembling method includes the following different step: loading the first terminal set into the plurality of first terminal set passages from a second end formed opposite the first end on the insulation body. 
         [0024]    According to another embodiment of the assembling method of the electrical connector, the assembling method includes the following different step: when loading each of the first terminal set into the first terminal set passages, the at least one support section comprises a non-elastic support section, the at least one support section fixedly leans against a wall surface of the first terminal set, and a fulcrum is formed in the connection between the at least one support section and the elastic contact section of the first terminal set to make the elastic contact section of the first terminal set to elastically move into the first terminal set passage. 
         [0025]    Each terminal structure includes an elastic contact section and at least one elastic/non-elastic support section. When corresponding terminals of a complementary electrical connector electrically contacts against the elastic contact section, the at least one elastic/non-elastic support section can provide better contact elasticity by producing elastic deformation or by providing the fulcrum in order to prevent damage from occurring to the terminal structure. According to the assembling method of the electrical connector, the above simplification of the insulation body structure is not only easy for assembling, it can also increase product yield such that manufacturing costs are decreased.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0037]    Please refer to  FIG. 1A , which illustrates a first embodiment of an electrical connector  1  of the present invention that complies with the USB 3.0 signal transmission stands and is used for electrically connection with a complementary electrical connector (not shown). The electrical connector  1  primarily includes a shielding housing  10 , an insulation body  20 , a first terminal set  30 , a second terminal set  40 , and a positioning part  50 . 
         [0038]    The shielding housing  10  primarily is formed from four wall surfaces, wherein an accommodating space  12  is formed within the confines of the four wall surfaces for accommodating the insulation body  20 . A hook  14  is formed recessing inwards on the left and right wall surfaces of the four wall surfaces. 
         [0039]    As shown in  FIGS. 1A and 1B , in the present embodiment, the entire body of the insulation body  20  is manufactured and formed as a unitary structure with plastic materials. The insulation body  20  includes a base part  22  and a mating part  24 , wherein a recessed portion  222  is formed below the base part  22  to accommodate the positioning part  50 . A slot  224  is formed on the left and right sides of the base part  22  respectively and is used correspondingly with the hooks  14  of the shielding housing  10  to fix the shielding housing  10  onto the insulation body  20 . The mating part  24  extends outward from the front of the base part  22  to a front end  246  along a horizontal direction. A mating surface  240  is formed on the mating part  24  to correspond to the connection of the complementary electrical connector. A plurality of first terminal set passages  242  and a plurality of second terminal set passages  244  are formed on the insulation body  20  to be respectively configured with the corresponding first terminal set  30  and the second terminal set  40 . The first terminal set passage  242  extends from the mating part  24  of the insulation body  20  to the base part  22  such that the first terminal set passage  242  is exposed below the mating part  24  and the base part  22  along the direction of extension. An end of the first terminal set passage  242  extends forward and passes through the front end  246  of the mating part  24 . The other corresponding end extends backward, passing past a vertical wall surface  2221  of the recessed portion of the base part  22  and then passing downwards through a horizontal wall surface  2223  of the recessed portion  222 . The second terminal set passage  244  extends from the upper surface of the mating part  24  of the insulation body  20  to the upper surface of the base part  22  such that the second terminal set passage  244  is exposed above the mating surface  240  of the mating part  24  and above the base part  22  along the direction of extension. The second terminal set passage  244  then extends downward and passes through the horizontal wall surface  2223  of the recessed portion  222  of the base part  22 . In further reference to  FIGS. 1A and 1C , on two opposing inner sidewalls near the front end  246  of the mating part  24  of each first terminal set passage  242 , a pair of upper blockers  2461  and lower blockers  2463  are respectively formed along a vertical direction, wherein the space between each pair of upper blockers  2461  and lower blockers  2463  define a slit  2465 . 
         [0040]    As shown in  FIGS. 1A and 1C , the first terminal set  30  is compatible with the USB 3.0 standards and is separated into a pair of first differential signal terminals  32 , a pair of second differential signal terminals  34 , and a ground signal terminal  36 . Each terminal  32 ,  34 , and  36  of the first terminal set  30  has an elastic contact section  300 , an elastic support section  302 , a plurality of horizontally directional holding sections  304 , and a vertically directional soldering pin section  306 . Two opposite sides of the elastic contact section  300  separately extend outward to form two wing sections  3002  to correspond to the two pairs of upper and lower blockers  2461 ,  2463  within the first terminal set passage  242 . Since the front of the elastic support section  302  is connected to the elastic contact section  300  and a plurality of bends  3022  (refer to  FIG. 1D ) are formed at the connection to the elastic contact section  300 , the back of the elastic support section  302  is connected to the plurality of holding sections  304 . In this manner, a mechanical structure akin to forming an elastic arm structure that can move up and down can be formed in the space between the elastic support section  302  and the elastic contact section  300 . In other embodiments, the first terminal set  30  further includes an elastic slice section (not shown) punched upward in the elastic contact section  300  so that a bend is formed in the connection between the elastic slice section and the elastic contact section  300 . The elastic slice section extends towards but does not overpass the mating surface  240  of the insulation body  20 . In this manner, greater contact elasticity may be provided for the electrical connector  1  when the electrical connector  1  is plugged or docked. 
         [0041]    As shown in  FIGS. 1A and 1B , the second terminal set  40  is compatible with the USB 1.0/2.0 standards and is separated into a pair of third differential signal terminals  42 , a ground signal terminal  44 , and a power signal terminal  46 . Each terminal  42 ,  44 , and  46  of the second terminal set  40  has an elastic contact section  400 , an elastic support section  402 , a horizontally directional first mating part  403 , a plurality of vertically directional holding sections  404  and  406 , a horizontally directional second mating part  405 , and a vertically directional soldering pin section  408 . Since the front of the elastic support section  402  is connected to the elastic contact section  400  and the back of the elastic support section  402  is connected along the horizontal direction to the plurality of holding sections  404 , an elastic spring arm structure that can move in the upward and downward directions is formed in the space from the elastic support section  402  to the elastic contact section  400 . In addition, the holding section  404 , the second mating part  405 , the holding section  406 , and the soldering pin section  408  jointly form a “n” structure, such that it may be disposed on top of the base part  22 . 
         [0042]    As shown in  FIGS. 1C and 1D , when the first terminal set  30  would like to be configured into the first terminal set passage  242 , the first terminal set  30  is loaded into the plurality of first terminal set passages  242  in a direction from the front end  246  of the insulation body  20  to the back of the insulation body  20 . Then, the holding section  304  of the first terminal set  30  is fixed within the first terminal set passage  343  on the underside of the insulation body  20  so that the elastic support section  302  of the first terminal set  30  is positioned in the first terminal set passage  242  and the position of the elastic contact section  300  of the first terminal set  30  is distributed on the mating surface  240  of the mating part  24  and near the front end  246 . In the present embodiment, the elastic contact section  300  of the first terminal set  30  is accommodated within the slit  2465  of the first terminal set passage  242  with the wing sections  3002  on the two sides of the elastic contact section  302  connected against the bottom of the upper blocker  2461 . Additionally, a spring arm structure is formed from the elastic support section  302  to the elastic contact section  300 . Therefore, the two wing sections  3002  of the elastic contact section  300  is limited to only be able to elastically move in the slit  2465  between the two pairs of upper blockers  2461  and lower blockers  2463  of the first terminal set passage  242 . In other words, the elastic contact section  300  of the first terminal set  30  will not extend to overpass the mating surface  240  of the mating part  24 . At the same time, the lower surface of the first terminal set  30  is exposed below the base part  22  and below the mating part  24  along the direction of extension of the first terminal set passage  242 , wherein the soldering pin section  306  by way of the vertical wall surface  2221  of the recessed portion  222  of the base part  22  extends and overpasses the horizontal surface wall  2223 . 
         [0043]    As shown in  FIGS. 1B and 1D , when the second terminal set  40  is configured to the second terminal set passage  244 , the second terminal set  40  is loaded into the plurality of second terminal set passages  244  from the top of the mating surface  240  of the insulation body  20  and from the top of the base part  22 . Then, the plurality of vertically directional holding sections  404  and  406  are respectively inserted and fixed into the plurality of vertically directional second terminal set passages  244  in front and behind the base part  20 , such that the elastic contact section  400  of the second terminal set  40  extends and overpasses the mating surface  240  of the mating part  240 . The distribution position of the elastic contact section  300  of the first terminal set  30  is closer to the front end  246  of the mating part  24  than the distribution position of the elastic contact section  400  of the second terminal set  40 . At the same time, the upper surface of the second terminal set  30  is exposed above the base part  22  and above the mating surface  240  along the direction of extension of the second terminal set passage  244 . The soldering pin section  408  extends downward and overpasses the horizontal wall surface  2223  of the recessed portion  222  of the base part  22 . 
         [0044]    As shown in  FIGS. 1A and 1D , the positioning part  50  is a plate structure having two sides forming a pair of wedge blocks  54 . The wedge blocks  54  are used for fastening into cavities (not shown) on the horizontal wall surface  2223  of the recessed portion  222  such that the positioning part  50  is installed in the spaced formed in the recessed portion  222 . In addition, a plurality of holes  52  are formed on the positioning part  50  for the solder section  306  of the first terminal set  30  and the solder section  408  of the second terminal set  40  to pass through and be properly positioned. 
         [0045]    As shown in  FIGS. 1A and 1D , when a USB 3.0 compliant complementary electrical connector is inserted into and is electrically connected to the electrical connector  1 , the corresponding terminals (not shown) of the USB 3.0 complementary electrical connector will be pressed against the elastic contact section  300  of the first terminal set  30  in the mating surface  240 . Similar to the mentioned elastic arm structure, the elastic support section  302  of the first terminal set  30  will provide the right side of the elastic contact section  300  of the first terminal set  30  the required elasticity. In this manner, the elastic contact section  300  of the first terminal set  30  may elastically move within the first terminal set passage  232 . In an embodiment, since the upper blocker  2461  of the first terminal set passage  242  is used for blocking upward movement of the wing section  3002  in the first terminal set passage  232 , the elastic movement distance in the upward direction by the elastic contact section  300  of the first terminal set  30  may be limited. For example, once the USB 3.0 compliant complementary electrical connector is unplugged from the electrical connector  1 , the elastic contact section  300  of the first terminal set  30  will not extend to overpass the mating surface  240  as a result of the rebounding effect from pressure release since the upper blocker  2461  will limit the elastic movement in the upward direction. The lower blocker  2463  may be used to block the downward movement of the wing section  3002  such that the downward elastic movement distance “D 1 ” of the elastic contact section  300  of the first terminal set  1  can be limited. Therefore, when the corresponding terminals of the USB 3.0 complementary electrical connector is inserted into the electrical connector  1  and presses against the elastic contact section  300  of the first terminal set  30 , the elastic contact section  300  of the first terminal set  30  will not sustain any damage as a result of too much pressure being placed on it by the corresponding terminals of the USB 3.0 compliant complementary electrical connector. 
         [0046]    As shown in  FIGS. 1C and 1D , it should be noted that since the elastic contact section  300  of the first terminal set  30  is accommodated within the slit  2465  of the first terminal set passage  242 , when the electrical connector  1  of the present invention is not electrically connected to any complementary electrical connectors, the elastic contact section  300  is connected against the bottom of the upper blocker  2461  and will not extend to overpass the mating surface  240 . As a result, when a USB 2.0 compliant complementary electrical connector is inserted into and electrically connected to the second terminal set  40  of the electrical connector  1 , the problem of the USB 2.0 compliant complementary electrical connector striking the first terminal set  30  will not occur. 
         [0047]    In reference to  FIG. 2 , a second embodiment of the electrical connector  2  of the present invention is shown. In comparison to the embodiment of the electrical connector  1 , the electrical connector  2  differs in that each terminal of the first terminal set  30  of the electrical connector  2  have an elastic contact section  300 , a first elastic support section  302 ′, a second elastic support section  303 ′, a plurality of horizontal holding sections  304 , and a plurality of vertical soldering pin sections  306 . The front of the first elastic support section  302 ′ is connected to the elastic contact section  300  and a plurality of bends  3022  are formed at that connection to the elastic contact section  300 , while the back of the first elastic support section  302 ′ is connected to the plurality of holding sections  304 . The front of the second elastic support section  303 ′ is connected to the elastic contact section  300  and a plurality of bends  3032  is formed at that connection to the elastic contact section  300 . At least one bend  3032  is exposed at the front end  246  of the mating part  24  of the insulation body  20 . Since a bottom end of the second elastic support section  303 ′ is preloaded and connected against the wall surface of a passage wall  2422  of the first terminal set passage  242 , not only will the first elastic support section  302 ′ provide the right side of the elastic contact section  300  the required elasticity, the second elastic support section  303 ′ can provide elasticity to the left side of the elastic contact section  300 . In this manner, the first elastic support section  303 ′, the elastic contact section  300 , and the second elastic support section  303 ′ form a mechanical structure akin to forming a simple support beam in civil engineering, wherein the deflection rate is smaller in comparison to that of the mentioned first embodiment such that the structure is not easy to deform. Due to this fact, the two sides of the elastic contact section  300  of the first terminal set  30  can more stably elastically move within the first terminal set passage  242 . It should be noted that the left and right side of the elastic contact section  300  referred herein pertains to the left and right sides of the diagram of the cross section A 1 -A 1 ′ of  FIG. 1D . Hence, in  FIG. 2 , the left and right sides of the elastic contact section  300  refers to the direction towards the front end  246  and the direction towards the base part  22  relative to the elastic contact section  300 . In addition, as shown in  FIG. 2 , the design of the first terminal set passage  242  of the electrical connector  2  of the second embodiment passing through the recessed portion  222  of the insulation body  20 , and the passage wall  2422  formed under the first terminal set passage  242 , are different from the first embodiment. This allows the first terminal set  30  of the electrical connector  2  of the second embodiment to come directly to an end after the insulation body  20  (in comparison to front end  246 ). In other words, the first terminal set  30  may be inserted from on top of the vertical wall surface  2221  of the recessed portion  222  and disposed in the first terminal set passage  242 . In terms of other positions and components, since they are the same as the first embodiment (such as the two opposite sides of the elastic contact section  300  of the first terminal set  20  respectively extend outward to form two wing sections—not shown—that are positioned between two pairs of upper and lower blockers  2461 ,  2463 ), they will not be further discussed here. 
         [0048]      FIG. 3  illustrates a third embodiment of the electrical connector  3  of the present invention. In comparison to the electrical connector  2  of the second embodiment, the first terminal set  30  of the third embodiment also includes an elastic slice section  3004  punched or stamped upward from the elastic contact section  300  such that a bend  3009  is formed at the connection between the elastic slice section  3004  and the elastic contact section  300 . The elastic slice section  3004  extends towards but not overpasses the mating surface  240  of the insulation body  20 . In this manner, the elastic movement distance D 2  may be increased (i.e. D 2 &gt;D 1 ) to provide higher contact elasticity when the electrical connector  3  is plugged. 
         [0049]      FIG. 4  illustrates a fourth embodiment of the electrical connector  4  of the present invention. In comparison to the electrical connector  1  of the first embodiment, each terminal of the first terminal set  30  has an elastic contact section  300 , an elastic support section  302 , a plurality of horizontal holding sections  304 , and a vertical soldering pin section  306 . The front of the elastic support section  302  is connected to the elastic contact section  300 , wherein a plurality of bends  3022  is formed at that connection to the elastic contact section  300 . At least one of the bends  3022  is exposed at the front end  246  of the mating part  24  of the insulation body  20 . The back of the elastic support section  302  is connected to the plurality of holding sections  304 . The elastic contact section  300  utilizes the wing sections on its two sides (not shown) to contact against the upper blocker (not shown) of the first terminal set passage  242 . In other embodiments, the elastic contact section  300  may also utilize wing sections to be preloaded on the upper blocker of the first terminal set passage  242 . The mechanical structure formed from the components between the elastic support section  302  to the elastic contact section  300  is akin to forming a cantilever that can move up and down. In terms of other parts and components, since they are the same as the first embodiment, they will not be further discussed here. 
         [0050]      FIG. 5  illustrates a fifth embodiment of the electrical connector  5  of the present invention. In comparison to the electrical connector  4  of the fourth embodiment, the design of the first terminal set passage  242  of the electrical connector  5  passing through the recessed portion  222  of the insulation body  20 , and the design of the passage wall  2422  being formed below the first terminal set passage  242  are different from the fourth embodiment. The first terminal set  30  of the electrical connector  5  can be directly inserted and disposed in the first terminal set passage  242  through the vertical wall surface  2221  of the recessed portion  222  of the insulation body  20 . In terms of other parts and components, since they are the same as the fourth embodiment, they will not be further discussed here. 
         [0051]      FIG. 6  illustrates a sixth embodiment of the electrical connector  6 . In comparison to the electrical connector  5  of the fifth embodiment, the first terminal set  30  of the electrical connector  6  also includes an elastic slice section  3004 , which is punched or stamped upward in the elastic contact section  300  such that a bend  3009  is formed at the connection between the elastic slice section  3004  and the elastic contact section  300 . The elastic slice section  3004  extends toward but does not overpass the mating surface  240  of the insulation body  20 . In this manner, the elastic movement distance D 2  may be increased (i.e. D 2 &gt;D 1 ) to provide higher contact elasticity when the electrical connector  6  is plugged. 
         [0052]      FIG. 7  illustrates a seventh embodiment of the electrical connector  7 . In comparison to the electrical connector  1  of the first embodiment, each terminal of the first terminal set  30  of the electrical connector  7  has an elastic contact section  300  and a non-elastic support section  302 ″, wherein the non-elastic support section  302 ″—without making elastic deformation—and the holding section  304  are nearly orthogonal connected and the non-elastic support section  302 ″ is also nearly orthogonal connected with the elastic contact section  300 . At least one bend  3022  is formed on the orthogonal connection between the elastic contact section  300  and the non-elastic support section  302 ″, wherein at least one bend  3022  is abut against the lower blocker  2463  of the first terminal set passage  242 . When a complementary electrical connector is electrically connected to the electrical connector  7  and presses against the elastic contact section  300  of the first terminal set  30 , the elastic contact section  300  will utilize the connection between the elastic contact section  300  and the non-elastic support section  302 ″ (i.e. bend  3022 ) as a pivot fulcrum to elastically move a specific distance D 3  within the first terminal set passage  242 . However, since the wing sections (not shown) of the two sides of the elastic contact section  300  of the first terminal set  30  is limited or restricted between the upper and lower blockers  2461 ,  2463  of the first terminal set passage  242 , the upper and lower blockers  2461 ,  2463  will limit the movement of the wing section of the first terminal set  30  in a vertical direction. In this manner, the upward and downward elastic movement distance D 3  of the elastic contact section  300  of the first terminal set  30  is limited. At the same time, the lower blocker  2463  also limits the movement of the non-elastic support section  302 ″ of the first terminal set  30  in a horizontal direction. 
         [0053]      FIG. 8  illustrates an eight embodiment of the electrical connector  8 . In comparison to the electrical connector  7  of the seventh embodiment, the first terminal set  30  of the electrical connector  8  also includes an elastic slice section  3004  that is punched or stamped upward in the elastic contact section  300  such that a bend  3009  is formed at the connection between the elastic slice section  3004  and the elastic contact section  300 . The elastic slice section  3004  extends towards but not overpasses the mating surface  240  of the insulation body  20 . In this manner, the elastic movement distance D 4  may be increased (i.e. D 4 &gt;D 3 ) such that higher contact elasticity may be provided when the electrical connector  8  is plugged. 
         [0054]    According to another embodiment of the present invention, an electronic device is provided with the mentioned embodiments of the electrical connector  1 ,  2 ,  3 ,  4 ,  5 ,  6 ,  7 , and  8  installed therein. The electronic device may include laptop computers, tablet computers, mobile phones, digital cameras, handheld storages, and the like. 
         [0055]    In addition, according to a ninth embodiment of the present invention, an assembling method of the electrical connector is provided. To facilitate better understanding of the assembling method, please refer to  FIGS. 1A-1D  of the electrical connector  1  of the first embodiment. The assembling method includes the following steps: 
         [0056]    From a front to back direction, the first terminal set  30  is respectively loaded into the plurality of first terminal set passages  242  from the front end  246  of the insulation body  20 . 
         [0057]    Then, the holding section  304  of the first terminal set  30  is fixed within the first terminal set passage  242  underneath the insulation body  20  such that the elastic support section  302  of the first terminal set  30  is positioned in the first terminal set passage  242 . The position of the elastic contact section  300  of the first terminal set  30  is distributed on the mating surface  240  of the mating part  24  near the front end  246 . In addition, the elastic contact section  300  of the first terminal set  30  is accommodated in the slit  2465  of the first terminal set passage  242 , wherein the two wing sections  3002  of the elastic contact section  300  lies between the upper and lower blockers  2461 ,  2463  (ex. wing section  3002  pressing against the bottom of the upper blocker  2461 ). The mechanical structure formed between the elastic support section  302  and the elastic contact section  300  is akin to forming a cantilever structure. The elastic support section  302  will provide the left side of the elastic contact section  300  the required elasticity. Since the two wing sections  3002  of the elastic contact section  300  is limited to only be able to elastically move in the slit  2465  between pairs of the upper and lower blockers  2461 ,  2463  within the first terminal set passage  242 . Therefore, the elastic contact section  300  of the first terminal set  30  will not extend overpasses the mating surface  240  of the mating part  24 . The soldering pin section  306  extends along the vertical wall surface  2221  of the recessed portion  222  of the base part  22  and overpasses the horizontal wall surface  2223 . 
         [0058]    From a top to bottom direction, the second terminal set  40  is loaded into the plurality of second terminal set passages  244  from the above of the base part  20  and the mating surface  240  of the insulation body  20 . Then, the plurality of vertical holding sections  404  and  405  of the second terminal set  40  is separately inserted and fixed in the front and back vertical second terminal set passages  244 . The elastic contact section  400  of the second terminal set  40  extends outward and overpasses the mating surface  240  of the mating part  24 , wherein the distribution position of the elastic contact section  300  of the first terminal set  30  is closer to the front end  246  of the mating part  24  than the distribution position of the elastic contact section  400  of the second terminal set  40  (as shown in  FIG. 1B ). In this instance, the top surface of the second terminal set  30  is exposed along the direction of extension of the second terminal set passage  244  on the base part  22  and on the mating surface  240 . The soldering pin sections  408  extend downwards, overpassing the horizontal wall surface  2223  in the recessed portion  222  of the base part  22 . 
         [0059]    A pair of wedge blocks  54  of two opposites sides of the positioning part  50  is fastened to cavities (not shown) at two sides of the horizontal wall surface  2223  of the recessed portion  222  below the insulation body  20 , such that the positioning part  50  is installed in the space formed by the recessed portion  222 . In this instance, a plurality of sockets  52  of the positioning part  50  is used for letting the soldering pin section  306  of the first terminal set  30  and the soldering pin section  408  of the second terminal set  40  to pass through and to be positioned. 
         [0060]    The insulation body  20  is accommodated in the accommodating space  12  of the shielding housing  10 . Hooks  14  on two side wall surfaces of the shielding housing  10  are used to correspondingly to the left and right two sides of the base part  22  of the insulation body  20  so that the shielding housing  10  can be sleeved onto the insulation body  21 . 
         [0061]    In addition, according to a tenth embodiment of the present invention, an assembling method for an electrical connector is provided. To facilitate better understanding of the assembling method of the tenth embodiment, please refer to  FIG. 2  of the electrical connector  2  of the second embodiment. The differences in the assembling method of the tenth embodiment in comparison to the ninth embodiment is described in the following steps: 
         [0062]    From a back to front direction, the first terminal set  30  is respectively inserted and disposed into the plurality of first terminal set passages  242  from the back end of the insulation body  20  (i.e. at the vertical wall surface  2221  of the recessed portion  222  opposite the front end  246 ). Then, the holding section  304  is fixed in the first terminal set passage  242  below the insulation body  20 , wherein the position of the elastic contact section  300  of the first terminal set  30  is distributed on the mating surface  240  of the mating part  24  close to the front end  246 . In this instance, the elastic contact section  300  of the first terminal set  30  is accommodated in the slit  2465  of the first terminal set passage  242 . The two wing sections (not shown) of the elastic contact section  300  lies between the upper blocker  2461  and the lower blocker  2463  within the first terminal set passage  242 . At least one bend  3032  formed at the connection between the elastic contact section  300  and the second elastic support section  303 ′ is exposed at the front end  246  of the mating part  24  of the insulation body  20 . Since the bottom end of the second elastic support section  303 ′ is preloaded and connected against the wall surface of the passage wall  2422  of the first terminal set passage  242 , elasticity can be provided to the left side of the elastic contact section  300 . In this manner, through the mechanical structure formed as an upward-downward moving cantilever between the first elastic support section  302 ′, the elastic contact section  300 , and the second elastic support section  303 ′, the two sides of the elastic contact section  300  of the first terminal set  30  may more stably move within the first terminal set passage  242 . In terms of the other steps, since they are the same as the ninth embodiment, they will not be further discussed here. 
         [0063]    In addition, according to an eleventh embodiment of the present invention, an assembling method for an electrical connector is provided. To facilitate better understanding of the assembling method of the tenth embodiment, please refer to  FIG. 4  of the electrical connector  4  of the second embodiment. The differences in the assembling method of the eleventh embodiment in comparison to the fourth embodiment is described in the following steps: 
         [0064]    After the first terminal set  30  is loaded into the plurality of first terminal set passages  242 , the at least one bend  3022  formed at the connection between the elastic support section  302  and the elastic contact section  300  is exposed at the front end  246  of the insulation body  20  while providing the required elasticity for the left side of the elastic contact section  300 . In terms of the other steps, since they are the same as the ninth embodiment, they will not be further discussed here. 
         [0065]    In addition, according to a twelfth embodiment of the present invention, an assembling method for an electrical connector is provided. To facilitate better understanding of the assembling method of the tenth embodiment, please refer to  FIG. 5  of the electrical connector  5  of the second embodiment. The differences in the assembling method of the eleventh embodiment in comparison to the fourth embodiment is described in the following steps: 
         [0066]    Along a back to front direction, the first terminal set  30  is respectively inserted and disposed within the first terminal set passages  242  from the back end of the insulation body  20  (i.e. vertical wall surface  2221  of the recessed portion  222 ). In terms of the other steps, since they are the same as the eleventh embodiment, they will not be further discussed here. 
         [0067]    In addition, according to a thirteenth embodiment of the present invention, an assembling method for an electrical connector is provided. To facilitate better understanding of the assembling method of the tenth embodiment, please refer to  FIGS. 7-8  of the electrical connectors  7  and  8  of the seventh and eighth embodiments. The differences in the assembling method of the eleventh embodiment in comparison to the ninth embodiment is described in the following steps: 
         [0068]    When loading the first terminal set  30  into the plurality of first terminal set passages  242 , the non-elastic support section  302 ″ is fixedly connected against the lower blocker  2463  on the wall surface of the first terminal set passage  242  to form a non-elastic support section. By utilizing an orthogonal connection, such as the bend  3022 , between the non-elastic support section  302 ″ and the elastic contact section  300  of the first terminal set  30 , a rotational fulcrum is formed such that the elastic contact section  300  of the first terminal set  30  may elastically move within the first terminal set passage  242 . In terms of the other steps, since they are the same as the ninth embodiment, they will not be further discussed here. 
         [0069]    In summary of the above, the electrical connector and the electronic device including the electrical connector of the present invention can not only simplify the insulation body to decrease the usage quantity of molds to lower manufacturing costs, each terminal structure also includes an elastic contact section and at least one elastic/non-elastic support section. When the corresponding terminals of a complementary electrical connector are electrically contacting the elastic contact section, the at least one elastic/non-elastic support section can provide better contact elasticity or flexibility to prevent the terminals structure from sustaining damage. As well, according to the assembling method of the electrical connector of the present invention, through the simplification of the insulation body, the assembling is easier, which results in higher product yields and decreased manufacturing costs. 
         [0070]    Although the preferred embodiments of the present invention have been described herein, the above description is merely illustrative. Further modification of the invention herein disclosed will occur to those skilled in the respective arts and all such modifications are deemed to be within the scope of the invention as defined by the appended claims.
