Description:
BACKGROUND OF THE INVENTION 
   1. Technical Field 
   The present invention relates to high frequency connectors and, more particularly, to a high frequency connector comprising two modules that can be easily manufactured and promptly assembled. The two modules of the disclosed high frequency connector can maneuverably connect with each other according to a required direction of signal transmission, so that a competent transmissive connection can be achieved when the two modules are assembled, and thus preventing generation of noise. The volume of each of the modules is precisely designed so that the high frequency connector facilitates reduction in power loss when being implemented for the purpose of signal transmission. 
   2. Description of Related Art 
   A presently developed high frequency connector for the purpose of signal transmission is typically constructed by assembling a first module  10  and a second module  20  (referring to  FIGS. 1 through 3 ). The first module  10  (referring to  FIG. 1 ) comprises a connecting element  101  having a through hole  102  at a predetermined position thereon for receiving a hollow connecting tube  103 . The connecting tube  103  has a threaded section  104  formed at the outer periphery thereof. The connecting element  101  and the connecting tube  103  are fastened together by making the connecting peripheries welded or wedged. The second module  20  (referring to  FIG. 2 ) comprises a connecting element  201  having a through hole  202  at a predetermined position thereon for receiving a hollow connecting tube  203 . Similarly, the connecting element  201  and the connecting tube  203  are fastened together by making the connecting peripheries welded or wedged. To combine the two modules  10  and  20 , referring to  FIGS. 3 and 3A , a C-shaped retaining ring  205  is coupled with an annular groove  2041  on the combining section  204  extending from the second module  20 . Further, a needle  206  jutting out from the second module  20  is received by a recess of a needle  105  inserted at the corresponding end of the first module  10  so that insulators  106  therein can be connected mutually. After the two modules  10 ,  20  are assembled for the purpose of signal transmission, the needles  105 ,  206  therein get connected mutually. At this time, the line contact between the two modules is liable to have intermittent interruptions due to external forces, which consequently leads to signal interference resulting in the generation of noise. Further, since the C-shaped retaining ring  205  assembled on the second module  20  is of a flat form, it is liable to have elastic fatigue after a period of use. Consequently, the combination between the two modules  10 ,  20  may become loosened and fail to bear relatively higher torsion force. 
   SUMMARY OF THE INVENTION 
   The present invention has been accomplished under these circumstances in view to ameliorate a conventional high frequency connector for signal transmission by improved combination of the modules, so that the stability of signal transmission can be enhanced and generation of noise can be efficiently eliminated. Also, connectors can maneuverably connect with each other according to a required direction of signal transmission so that the integrated connectors can have a precise volume after components are assembled. 
   It is one objective of the present invention to provide a high frequency connector, which is constructed by assembling a first module and a second module mutually. The first module comprises a connecting element having a through hole for receiving an insulator and having a gap formed at one side of the through hole. An L-shaped needle is inserted into a through hole of the insulator and an upper section of the L-shaped needle further extends in a horizontal segment of the connector. Two insulators are respectively arranged at a bent portion of the L-shaped needle between the connecting element and the connector, and the horizontal segment of the connector. The first module constructed as described above may further comprise a plurality of legs extending from the connecting element downward. By the gap at the side of the connecting element, the connecting element can be attached by the connector along a straight direction (i.e. 180°) or with an angle of 90°. 
   It is another objective of the present invention to provide a high frequency connector, which is constructed by assembling a first module and a second module mutually. The second module comprises a connecting element having a through hole formed at one side thereof and can be locked with a connector by screwing. The connector has a relatively larger accommodating space for receiving an insulator and the insulator permits a needle to pass through. An effective end of the needle pierces through the connecting element and juts out of the connecting element into a relatively smaller through hole. Additionally, the needle has another end near the connector contacting an insulator. Further, a positioning element is locked with a fabricating hole by screwing. Moreover, a connector is fastened to the connecting element at one end where the needle protrudes. An outer end of the smaller through hole of the connecting element forms a chamfered section. The chamfered section permits an enlarged sectional area so that the air retained therein as well as the air retained in a vacant space of the through hole can function as insulation during signal transmission. Also, the chamfered section balances impedance errors that may be caused by different diameters of the needles of the first and second modules when the two modules are mutually engaged. 
   It is another objective of the present invention to provide a high frequency connector that is constructed by assembling a first module and a second module mutually. A C-shaped retaining ring is coupled with an annular groove of a connecting element of the second module and has an effective end outwardly warped for facilitating the combination between the connecting element and a connector. Thereby, the assembled components can be firmly fastened and effectively protected from loosening or coming off when an external pulling or dragging force is applied. 
   It is another objective of the present invention to provide a high frequency connector, which is constructed by assembling a first module and a second module. A connector, which is to be locked with a connecting element by screwing for converting the extension direction into an angle of 90°, may have a connecting end and a converting end formed integrally so that the construction and manufacture of the connector can be simplified. 
   It is yet another objective of the present invention to provide a high frequency connector, which is constructed by assembling a first module and a second module. The second module comprises a connecting element having a larger accommodating space for receiving an insulator. The insulator passes through a needle therein and has one end being formed integrally with or separately from a spacer having an indentation. By the spacer having the indentation, air isolation can be achieved between the indentation and the needle so as to balance impedance errors occurring at an interface between the needle and an extended antenna or coaxial cable adjacent to a through hole. 
   It is still another objective of the present invention to provide a high frequency connector, which is constructed by assembling a first module and a second module. A needle jutting out from the second module and a needle settled in the first module are partially connected, and the two modules are spaced with an interval. In virtue of the interval, line contact between the two modules can be free from intermittent interruptions so that generation of noise is efficiently prevented.

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
   Referring to  FIGS. 8 and 9 , a high frequency connector of the present invention comprises a first module  4  and a second module  9 . 
   The first module  4  (referring to  FIGS. 4 and 5 ) comprises a connecting element  1  having a through hole  11  for receiving an insulator  41 , and having a gap  12  formed at one side. By this gap  12 , the mating length between the connecting element  1  and a connector  2  can be enhanced. An L-shaped needle  3  can be inserted into a through hole  411  of the insulator  41  while extending into a 90° angle to penetrate a horizontal segment  21  of the connector  2  so that a relative rotation between the connecting element  1  and the connector  2  is restricted. A positioning insulator  42  is settled between the connecting element  1  and the connector  2  at the bent portion of the L-shaped needle  3 , while an insulator  43  is inserted into the horizontal segment  21 . The positioning insulator  42  herein functions for eliminating impedance errors. The first module  4  constructed as above may further comprise a plurality of legs  13  extending downward from the connecting element  1  or extending sideways from the connector  2  and, in either case, by the gap  12  at the side of the connecting element  1 , the connecting element  1  can be attached by the connector along a straight direction (i.e. 180°) or with an angle of 90°. (Hereinafter the connecting element  1  having the plural legs  13  extending downward is taken as an exemplificative embodiment). 
   The second module  9  (referring to  FIGS. 6 and 7 ) comprises a connecting element  5  that has a through hole  51  formed at one side thereof and can be locked with a connector  6  by screwing. By this through hole  51 , the mating length between the connecting element  5  and the connector  6  can be enhanced. Relative rotation between the connecting element  5  and the connector  6  is restricted. An insulator  91  is inserted into a relatively larger accommodating space  52  and receives a needle  7  that penetrates through. An effective end of the needle  7  pierces through the connecting element  5  and juts out from a relatively smaller through hole  53 . Additionally, the needle  7  has the end near the connector  6  contacting with an insulator  92 . Then, a positioning element  62  is locked with a fabricating hole  61  of the connector  6  by screwing. Moreover, a connector  8  is fastened to the connecting element  5  at the end where the needle  7  protrudes. The second module  9 , constructed as above, further comprises a chamfered section  54  formed on an outer end of the relatively smaller through hole  53  of the connecting element  5 . The chamfered section  54  permits an enlarged sectional area so that the air retained therein as well as the air retained in the vacant space of the through hole  53  can function as insulation during signal transmission. Also, the chamfered section  54  balances impedance errors that may be caused by different diameters of the needles of the first and second modules  4  and  9  when the two modules  4  and  9  are mutually engaged. 
   For assembling the connecting element  5  with the connector  8  of the second module  9 , referring to  FIGS. 7 ,  7 A,  7 B and  7 C, a C-shaped retaining ring  56  which has an effective end warped outwardly is wedged into an annular groove  55  of the connecting element  5 . Since the wedged C-shaped retaining ring  56  would contract toward the center of the annular groove  55 , a force would act inwardly and the C-shaped retaining ring  56  can be easily guided toward and positioned in a positioning groove  81  of the connector  8  (referring to  FIG. 7B ). Thus, when an external force pulls the C-shaped retaining ring  56  outward from the annular groove  55 , which results in a force acting outwardly to make the C-shaped retaining ring  56  depart from the connecting element  5 , but the positioning groove  81  of the connector  8  can efficiently retain the C-shaped retaining ring  56  from separating (referring to  FIG. 7C ). Thereby, the components can be firmly and effectively protected from loosening and coming off when an external pulling or dragging force is applied. 
   The connector  6 , which is to be locked with the connecting element  5  by screwing for converting the extension direction into an angle of 90°, has a connecting end  63  and a converting end  64  that may be integrally formed (as shown in  FIG. 6 ) so that construction and manufacturing of the connector  6  can be simplified. 
   The insulator  91  of the second module  9 , which is inserted into the relatively larger accommodating space  52  of the connecting element  5  and receives the needle  7 , pierced through, may be formed integrally with or separately from a spacer  93  that has an indentation  931  (referring to  FIG. 6 ). The spacer  93  having the indentation  931  balances the impedance errors occurring at a connecting portion  57  of the needle  7  (i.e. the section where the needle  7  contacts with an extended antenna or coaxial cable adjacent to the through hole  51 ). The indentation  931  may be sized according to the diameter of the antenna or cable it contacts. 
   When the first and second modules  4  and  9  are assembled to construct a high frequency connector  30 , the needle  7  jutting out from the second module  9  and the needle  3  settled in the first module  4  are partially connected (referring to  FIG. 9 ), and the two modules  4  and  9  are spaced with an interval  94 . In virtue of the interval  94 , line contact between the two modules  4  and  9  can be free from intermittent interruptions so that the generation of noise can be efficiently prevented. 
   Referring to  FIG. 10 , the high frequency connector  30  composed of the first module  4  and the second module  9  is applied to a board  40  for the purpose of signal transmission. The legs  13  of the connecting element  1  of the first module  4  are fastened at predetermined locations on the board  40 , whereby the connector  6  of the second module  9  can be turned to a desired direction according to the required direction of a connecting module (referring to the arrow in  FIG. 10  showing the rotating direction). Hence, the high frequency connector  30  has practical adaptability and maneuverability. 
   The disclosed high frequency connector  30  constructed by assembling the first and second modules  4  and  9  has the following advantages: 
   1. The gap formed at the side of the connecting element  1  of the first module  4  facilitates enhancement of the mating length and restriction of the relative rotation between the connecting element  1  and the connector  2 . Also, the connecting element  1  can be attached by the connector  2  at a 180° angle (straight direction) or with an angle of 90° as required. 
   2. The chamfered section  54  formed at the end of the connecting element  5  of the second module  9  permits an enlarged sectional area, so that the air retained therein as well as the air retained in the vacant space of the through hole  51  can function as insulation during signal transmission. Further, the chamfered section  54  balances impedance errors that may be caused by the different diameters of the needles  3  and  7  of the first and second modules  4  and  9  when the two modules  4  and  9  are mutually engaged. 
   3. The C-shaped retaining ring  56  settled in the annular groove  55  of the connecting element  5  of the second module  9  has the effective end outwardly warped for facilitating the combination between the connecting element  5  and the connector  8 . Thereby, the assembled components can be firmly positioned and effectively protected from loosening or coming off when an external pulling or dragging force is applied. 
   4. In the disclosed high frequency connector  30 , the needle  7  jutting out from the second module  9  and the needle  3  settled in the first module  4  are partially connected and the two modules  4  and  9  are spaced with an interval. In virtue of the interval, line contact between the two modules  4  and  9  can be free from intermittent interrupts so that the generation of noise can be efficiently prevented. 
   5. The connector  6 , which is to be locked with the connecting element  5  by screwing for converting the extension direction into an angle of 90°, has the connecting end  63  and the converting end  64  formed integrally so that the construction and manufacture of the connector  6  can be simplified. 
   6. The insulator of the second module  9 , which is inserted into the relatively larger accommodating space  52  of the connecting element  5  and receives the needle  7 , pierced through, is formed integrally with or separately from the spacer  93  that has the indentation  931 . The spacer having the indentation balances the impedance errors occurring at the connecting portion  57  of the needle  7  (i.e. the place where the needle  7  contacts with an extended antenna or coaxial cable adjacent to the through hole  51 ). The indentation  931  may be sized according to the diameter of the antenna or cable it contacts. 
   7. In the high frequency connector  30  constructed by assembling the first and second modules  4  and  9 , the second module  9  can have the direction changed according to the required direction of a connecting module, so that the high frequency connector  30  has practical adaptability and maneuverability. 
   Although a particular embodiment of the invention has been described in detail for purposes of illustration, it will be understood by one of ordinary skill in the art that numerous variations will be possible to the disclosed embodiments without going outside the scope of the invention as disclosed in the claims.
