Title: Connector

Description:
BACKGROUND OF THE INVENTION 
     1. Technical Field 
     The present invention relates to a connector. 
     2. Related Art 
     Conventionally, there is a known connector which can prevent a lever from collapsing even if there is a slight external force or a vibration before or during insertion of a flexible printed circuit board (substrate) to save the time and effort of flexible printed circuit board insertion work (for example, refer to Japanese Unexamined Patent Publication No. 2009-129860). 
     However, with regard to the conventional connector, disclosed is only a configuration which can prevent the lever from collapsing due to a vibration, for example, before the insertion of the substrate or on other occasions. Therefore, the user has to determine whether the substrate is inserted up to a suitable position. Furthermore, the user needs to operate the lever, that is, to raise or push down the lever before and after making the determination. 
     SUMMARY 
     The present invention been devised to solve the problems described above, and an object thereof is to provide a connector in which only insertion of a substrate up to a proper position automatically completes an electrical connection between the substrate and a contact point member, and which allows the state of the connector to be recognized from the outside. 
     In accordance with one aspect of the present invention, there is provided 
     a connector including 
     a housing with an insertion recessed portion into which a substrate is to be inserted, 
     a contact point member that is installed in the housing and that includes a contact point portion which protrudes into the insertion recessed portion and makes an electrical connection to a conductive portion of the substrate to be inserted, and 
     a position determining member which moves the contact point member, when the substrate is inserted into the insertion recessed portion of the housing, in such a manner that the contact point portion is retracted from the insertion recessed portion, and then protrudes into the insertion recessed portion to make an electrical connection to the conductive portion of the substrate. 
     With this configuration, only the insertion of the substrate into the insertion recessed portion of the housing may automatically complete the electrical connection between the substrate and the contact point member. 
     The position determining member preferably moves depending on each movement in such a manner that the movement of the position determining member is recognizable from the outside of the housing. 
     This configuration enables checking for whether the electrical connection between the conductive portion of the substrate and the contact point portion of the contact point member is properly made to be performed from the outside of the housing, without needing additional work. 
     The position determining member may include 
     a movement member that is movable between a first position where the contact point portion of the contact point member is retracted from the insertion recessed portion, and a second position where the contact point portion of the contact point member protrudes into the insertion recessed portion, and 
     a latching member that position-determines the movement member in the second position, then moves to transport the movement member to position-determine the movement member in the first position when the substrate is inserted into the insertion recessed portion of the housing, and thereafter cancels the position-determined state when the substrate is inserted up to a proper position. 
     With this configuration, a state of an internal portion obtained by the insertion of the substrate into the housing may be recognized from a movement position of the movement member. In addition, since the position-determination of the movement member is achieved by the latching member, the state of the internal portion can be exactly recognized by establishing clear matching between the positions and the states of the internal portion. 
     The first position of the movement member may be distinguishable from the second position where the movement member protrudes from the housing. 
     With this configuration, the state, in which the contact point member is retracted from the insertion recessed portion by the substrate being inserted into the housing, can be easily recognized from the movement of the movement member, that is, from the outside of the housing. 
     The movement member preferably includes a shaft portion, and the contact point member preferably includes a holding portion that elastically holds the shaft portion of the movement member in a state of being installed in the housing. 
     With this configuration, not only an additional member for holding the movement member is made unnecessary but also a smooth movement of the movement member may be performed because of the elastic holding. 
     The holding portion of the contact point member preferably urges the movement member positioned in the first position in such a manner that the movement member is able to move to the second position. 
     With this configuration, only the canceling of the latched state by the latching member may automatically make a movement of the movement member that is positioned-determined in the first position to the second position, because of the elastic force exerted by the holding portion of the contact point member. 
     The movement member preferably includes an abutting receiving portion, and the movement member preferably moves from the second position to the first position when the substrate which is to be inserted into the housing is brought into contact with the abutting receiving portion and then inserted inward further. 
     With this configuration, the insertion of the substrate into the housing may enable the movement of the movement member from the second position to the first position via the abutting receiving portion. 
     The movement member may be supported by the holding portion of the contact point member in such a manner as to rotate about the shaft portion, and the movement of the movement member from the first position to the second position may be achieved by the rotation about the shaft portion in a direction in which the substrate is inserted. 
     With this configuration, the second position can be provided inside the housing, and the movement member may be configured in a manner not to protrude from the housing after the installation of the substrate. This makes the whole structure compact. 
     The substrate preferably includes a latching notch portion, the movement member preferably moves from the first position to the second position by the substrate being inserted up to an installation completion position, and the abutting receiving portion of the movement member may be latched onto the latching notch portion of the substrate. 
     With this configuration, since only the insertion of the substrate up to a proper position completes the latching of the abutting receiving portion of the movement member onto the latching notch portion of the substrate, slipping-off of the substrate may be prevented. 
     The latching member may include a pressure receiving portion that is pressed by a leading end edge of the substrate inserted into the insertion recessed portion of the housing, an elastic portion that elastically deforms by the pressure receiving portion being pressed, and an arm portion that has a latch protrusion portion and separates the latch protrusion portion from the movement member by the elastic member which elastically deforms, 
     and the movement member may include a first latch recessed portion onto which the latch protrusion portion formed in the arm portion is able to be latched when the movement member is positioned in the first position, and a second latch recessed portion onto which the latch protrusion portion formed in the arm portion is able to be latched when the movement member is positioned in the second position. 
     According to the present invention, whether the movement member has moved is recognizable from the outside by only inserting the substrate into the insertion recessed portion of the housing. Accordingly, whether the electrical connection between the conductive portion of the substrate and the contact point portion of the contact point member, which is performed inside the housing, is properly performed can be checked, without needing excessive work.

Furthermore, the following description is only an example in nature, and is not intended to limit the present invention, applications thereof, or uses thereof. 
     (First Embodiment) 
       FIG. 1  is an overall view illustrating a connector according to a first embodiment, and  FIG. 2  is a perspective exploded view illustrating the connector. The connector is configured by installing a contact point member  2 , a latching member  3 , and a movement member  4  to a housing  1 . 
     As illustrated in  FIGS. 3A and 3B , the housing  1  is a product manufactured by molding an electrically insulating resin material into an approximately rectangular paralleled piped shape. A recess  5  and an insertion recessed portion  6  are formed in the housing  1 . The recess  5  is open in the direction of the upper surface and in the direction of the front surface. The insertion recessed portion  6  is provided under the recess  5  and is open in the direction of the front surface. The recess  5  and the insertion recessed portion  6  are separated by a partition wall  7 . A front end portion of the partition wall  7  is positioned on the rear side compared to a position of the front surface of the housing  1 , and notches  8  are formed at both sides of the partition wall, respectively. Guide recessed portions  9  are formed in both side surfaces of the recess  5  and the insertion recessed portion  6 , and shaft portions  47  of movement members  4  described later are arranged in the guide recessed portions  9 , respectively. In addition, a front portion of each of the both side surfaces of the recess  5  and the insertion recessed portion  6  is relatively broad in a width direction. This facilitates insertion of a substrate  17  (refer to  FIG. 1 ). 
     A plurality of guide holes  10  are formed on the partition wall  7 , at predetermined intervals in the width direction. The plurality of guide holes  10  are formed to communicate with the upper and lower surfaces and extend in the backward direction. Furthermore, guide groove portions  11  are formed in the bottom surface which makes up the insertion recessed portion  6 . The guide groove portions  11  are formed to correspond to the guide holes  10 , respectively and extend in the forward and backward directions. The guide holes  10  and the guide groove portions  11  communicate with insertion holes  12  in the rear surface side of the housing  1 . The insertion holes  12  are open in the direction of the rear surfaces of the recess  5  and the insertion recessed portion  6  and in the direction of the rear surface of the housing  1 . The guide holes  10 , the guide groove portions  11 , and the insertion holes  12 , which are positioned at both side ends, make up a first attachment portion  13  for installing the latching member  3 . The plurality of insertion holes  12 , arranged in parallel between the insertion holes  12 , make up a second attachment portion  14  for installing the contact point member  2 . In each of the first attachment portions  13 , a latching portion  15 , which is elastically deformable downward and has a latching pawl  15   a  protruding upward from a leading end part, is formed in a rear end portion of the bottom surface making up the insertion hole  12 . A latching hole  16  in the rectangular shape, which communicates with the insertion hole  12 , is formed in a position corresponding to each of the latching portions  15 , in an upper wall making up the insertion hole  12 . 
     A lower surface of the front end of the partition wall  7  is an upward-inclined surface that is gradually inclined upward, along the direction of facing toward the front side. Furthermore, a front end part of the bottom surface of the insertion recessed portion  6  is a downward-inclined surface that is gradually inclined downward, along the direction of facing toward the front side. Furthermore, a front end part of an inside surface of each of both side walls is a sideways-inclined surface that is gradually inclined from side to side, along the direction of facing toward the front side. These inclined surfaces are for facilitating an insertion of the substrate  17  (refer to  FIG. 1 ) into the insertion recessed portion  6 . Here, an FPC (Flexible Printed Circuits: flexible printed circuit board) is used for the substrate  17 . Latching notches  18  are formed in both side end portions of the substrate  17 , respectively. Abutting receiving portions  39  of the movement member  4  described later are latched onto the latching notches  18 , respectively when the substrate  17  is inserted into the insertion recessed portion  6  of the housing  1 . 
     A release recessed portion  19  is formed in each of both end portions of the front surface of the housing  1 , and an approximately L-shaped groove portion  20  being open in the direction of the front surface is formed in the release recessed portion  19 . A fixation fitting  21  is fixed by being pressed into each groove portion  20  from the front side. The fixation fitting  21  is a metal plate member bent in the shape of a letter approximately like C. In the fixation fitting  21 , the upper end wall and the side wall are pressed into the groove portion  20 , the lower end wall is narrow in width, and the lower surface protrudes downward from the lower surface of the housing  1 . 
     As illustrated in  FIG. 5 , the contact point member  2  includes an installation portion  22  to be installed in the insertion hole  12 , a first arm portion  23  and a second arm portion  24  which extend forward from an upper and a lower end portions of the front end edge of the installation portion  22 , respectively, and a terminal portion  25  which extends from a lower portion of the rear end. The contact point member  2  is manufactured by performing press working on a conductive elastic plate. The contact point members  2  are installed in the second attachment portions  14 , respectively that are installed in parallel in the housing  1 . 
     Protrusion portions  26  are formed in an upper position in the first arm portion  23  and a lower position in the second arm portion  24 , respectively in the front end edge of the installation portion  22 . Furthermore, a press-in protrusion portion  27 , which protrudes upward in the vicinity of the protrusion portion formed in the upper position, is formed in the upper end edge of the installation portion  22 . 
     The first arm portion  23  protrudes forward from the installation portion  22 , and a contact point portion  28  is formed in a manner to protrude downward from the leading end part of the first arm portion  23 . The lower side of the leading end edge of the contact point portion  28  has an inclination portion  29  that gradually faces upward, along the direction of facing toward the leading end. A holding piece  30  is formed in the leading end part of the contact point portion  28 . The holding piece  30  bulges upward substantially in the shape of a letter C. The holding piece  30  is in the form that conforms the upper half part of the shaft portion  43  of the movement member  4  described below. The holding piece  30  holds the shaft portion  43  to support the movement member  4  in a rotatable manner. 
     The second arm portion  24  obliquely extends downward from the installation portion  22 , and thereafter protrudes in parallel with the first arm portion  23 . A pressing portion  31 , which protrudes upward from the leading end part of the second arm portion  24 , is formed in a position facing the contact point portion  28  of the first arm portion  23 . An inclination portion  32 , which faces the inclination portion  29  of the first arm portion  23 , is formed on the upper side of the leading end edge of the pressing portion  31 . 
     As illustrated in  FIG. 6 , the latching member  3  includes an installation portion  33 , installed in the insertion hole  12 , and an arm portion  34 , which extends forward from an upper portion of the front end edge of the installation portion  33 . The latching member  3  is obtained by performing a molding process using synthetic resin material. The two latching members  3  are installed in the first attachment portions  13  installed in parallel at both sides of the second attachment portion  14 , respectively. A pressure receiving portion  35 , which protrudes forward, is formed on a lower portion of the front end edge of the installation portion  22 . The pressing pressure receiving portion  35  is pressed by the substrate  17  inserted into the insertion recessed portion  6  of the housing  1 . An elastic portion  36  in the shape of a letter approximately U and a stopping portion  37 , in succession to the elastic portion  36 , are formed to extend from the rear end edge of the installation portion  22 . The elastic portion  36  elastically deforms as the front end edge of the installation portion  22  is pushed by the substrate  17  inserted into the insertion recessed portion  6  as described below. The stopping portion  37  elastically deforms the latching portion  15  formed in the first attachment portion  13  of the housing  1 , so that a rear end upper portion is latched onto a latching hole  16  of the housing  1  and the latching pawl  15   a  which is on top is latched onto a rear end lower portion. A latch protrusion portion  38 , which protrudes forward, is formed on an upper portion of the front end edge of the arm portion  34 . 
     As illustrated in  FIGS. 7A and 7B , the movement member  4  is manufactured in the shape of a long plate by performing a molding process using synthetic resin material. The abutting receiving portions  39  protrude downward from both end portions of the movement member  4 . A lower edge portion of each of the abutting receiving portions  39  is an inclination portion  39   a  which gradually protrudes downward, along the direction of facing toward the rear side. Thereby, if the substrate  17  is inserted into the insertion recessed portion  6 , the leading end edge of the substrate  17  comes into contact with the inclination portion  39   a,  and the movement member  4  is made to be rotatable via the abutting receiving portion  39 . Multiple guide walls  41  are formed in the upper surface half part of the movement member  4 . The plurality of guide walls  41  are configured from a plurality of groove portions  40  that are provided at predetermined intervals in the width direction. Furthermore, a shaft portion  43  is formed every between the guide walls  41 , by a communication hole  42  that is provided in the bottom surface of the first groove portion  40  in a manner to communicate upward and downward. The shaft portion  43  is configured from two plane surfaces, which are opposite to and in parallel with each other, and a pair of arc surfaces, which bulge outward. The shaft portion  43  is held by the holding piece  30  of the contact point member  2 , and the movement member  4  is supported in a rotatable manner. Latch receiving portions  44 , which protrude in the opposite direction of the abutting receiving portions  39 , are formed at both end portions of the movement member  4 , respectively. A first latch recessed portion  45  is formed in a lower portion of the latch receiving portion  44 , and a second latch recessed portion  46  is formed in an upper portion of the latch receiving portion  44 . A plane surface and an arc surface are in succession to each other in the first latch recessed portion  45  and the second latch recessed portion  46 . The latch protrusion portions  38 , which are formed in the arm portions  34  of the latching member  3 , are latched onto or unlatched from the latch recessed portions  45  and  46 . The lower surface of the movement member  4  comes into contact with the upper surface of the recess  5 , and the upper surface of the movement member  4  is positioned in a horizontal position (a second position) where the upper surface of the movement member  4  is flush with the upper surface of the housing  1 , in a state in which the latch protrusion portion  38  is latched onto the second latch recessed portion  46 . On the other hand, the movement member  4  is positioned in a standing-up position (a first position) where the movement member  4  protrudes from the recess  5 , in a state in which the latch protrusion portion  38  is latched onto the first latch recessed portion  45 . The shaft portion  47 , which is guided by the guide recessed portion  9  of the housing  1 , protrudes from the end face of the latch receiving portion  44 . When the movement member  4  is positioned in the standing-up position, the first arm portion  23  of the contact point member  2  is elastically deformed, urging the shaft portion  43  to move downward. For this reason, when the latch protrusion portion  38  is unlatched from the first latch recessed portion  45 , the urging force makes the movement member  4  return back to the horizontal position. Moreover, the remaining half part (the side in which the guide wall  41  is not formed) of the movement member  4  serves as an operation portion  48  which is held by fingers for operation. 
     The connector having the above-mentioned configuration is assembled as follows. 
     First, the contact point members  2  are inserted into the insertion holes  12  in the second attachment portion  14  of the housing  1 , respectively from the rear end side. The contact point member  2  is installed in the housing  1  when the installation portion  22  is inserted into the insertion hole  12  and the press-in protrusion portion  27  is brought into pressure contact with the inside surface of the insertion hole  12 . In the installed state, the contact point portion  28  of the first arm portion  23  protrudes into the insertion recessed portion  6 . In addition, the holding piece  30  protrudes into the recess  5 , and a gap is formed between the leading end part of the holding piece  30  and the upper surface of the partition wall  7 . 
     Subsequently, the movement member  4  is installed by using the holding piece  30  of the contact point member  2  which has protruded into the recess  5  of the housing  1 . The shaft portion  43  of the movement member  4  is inserted into the gap that is formed between the leading end part of the holding piece  30  and the bottom surface of the recess  5 , from the front side. The holding piece  30  deforms elastically first by the shaft portion  43  of the movement member  4 , and then returns to its original form, to hold the shaft portion  43 . As a result, the installation of the movement member  4  is completed. In this state, the movement member  4  is position-determined in the horizontal position. 
     After that, the latching member  3  is inserted into the insertion hole  12  formed in the second attachment portion  14 , from the rear surface side. The installation of the latching member  3  may be completed by inserting the arm portion  34  into the insertion hole  12 , and press-fitting the installation portion  33 . In this state, the latch protrusion portion  38  of the latching member  3  is latched onto the second latch recessed portion  46  of the movement member  4  positioned in the horizontal position. 
     Thus, in the assembled connector, when installing the substrate  17 , insertion of the substrate  17  into the insertion recessed portion  6  of the housing  1  as it is from the state illustrated in  FIGS. 8A and 8B  may complete the installation of the substrate  17 . As a result, the leading end edge of the substrate  17  comes into contact with the abutting receiving portion  39  of the movement member  4  which protrudes into the insertion recessed portion  6  as illustrated in  FIG. 9A . In this state, the contact point portion  28  of the contact point member  2  protrudes into the insertion recessed portion  6 . As illustrated in  FIG. 9B , the latch protrusion portion  38  formed at the leading end of the arm portion  34  of the latching member  3  is latched onto the second latch recessed portion  46  of the movement member  4  and the movement member  4  is position-determined in the horizontal position (second position). 
     And, if the substrate  17  is pushed into the insertion recessed portion  6 , as illustrated in  FIG. 10B , the abutting receiving portion  39  is pressed. Consequently, the movement member  4  counterclockwise rotates about the shaft portion  43  while resisting against the elastic force applied from the first arm portion  23  of the contact point member  2 . Thereby, the latch protrusion portion  38  of the latching member  3  is unlatched from the second latch recessed portion  46  of the movement member  4 . As illustrated in  FIG. 10A , the first arm portion  23  of the contact point member  2  elastically deforms upward, and the contact point portion  28  is retracted from the insertion recessed portion  6 . 
     Then, as the substrate  17  is pushed into the insertion recessed portion  6  gradually, as illustrated in  FIG. 11A , the movement member  4  rotates to be in the standing-up position (first position), and the contact point portion  28  is completely retracted from the insertion recessed portion  6 . For this reason, a smooth insertion of the substrate  17  is performed without being hindered by the contact point portion  28 . In addition, as illustrated in  FIG. 11B , the latch protrusion portion  38  of the latching member  3  is latched onto the first latch recessed portion  45  of the movement member  4 . As a result, the movement member  4  is position-determined in the above-mentioned standing-up position (first position). 
     When the substrate  17  is further pushed into the insertion recessed portion  6 , as illustrated in  FIG. 12B , the leading end edge of the substrate  17  comes into contact with the pressure receiving portion  35  of the latching member  3 . When the substrate  17  is pushed more inwards, the elastic portion  36  elastically deforms and the arm portion  34  moves backward. Thereby, the latch protrusion portion  38  provided at a leading end of the latching member  34  is unlatched from the first latch recessed portion  45  of the movement member  4 . As a result, the movement member  4  enters a freely rotatable state, so that the movement member  4  rotates from in the standing-up position to in the horizontal position due to the elastic force of the first arm portion  23  of the contact point member  2 . At this time, the abutting receiving portion  39  of the movement member  4  is latched onto the latching notch portion  18  of the substrate  17  so that slipping-off of the substrate  17  from the housing  1  may be prevented. As illustrated in  FIG. 12A , the contact point portion  28  of the contact point member  2  comes into pressure contact with the conductive portion  17   a  of the substrate  17 , and thus an electrical connection state is obtained. 
     As the insertion of the substrate  17  into the insertion recessed portion  6  in the housing  1  is in progress in this way, the movement member  4  rotates to be in the standing-up position, and after that returns to be in the horizontal position when the inserted substrate  17  reaches a proper position. Therefore, the user can check whether the installation of the substrate  17  is completed from the outside of the housing  1  by recognizing the rotation state of the movement member  4 . Since the slipping-off of the substrate  17  from the housing  1  is prevented thanks to the abutting receiving portion  39  of the movement member  4 , the stably installed state can be achieved. 
     (Second Embodiment) 
       FIG. 13  illustrates a connector according to a second embodiment. Because this connector is different from that of the first embodiment only in terms of one part of the construction of a movement member  4 , but is almost the same in terms of the other configurations, a description of what has not any different construction is not repeated. 
     As illustrated  FIGS. 16A to 16B , a plurality of guide walls  50  are formed in a rear portion of the upper surface of the movement member  4 . The plurality of guide walls  50  are configured from a plurality of groove portions  49  and arranged at predetermined intervals in the widthwise direction. A communicating hole  51  which communicates with the upper surface and the lower surface is provided in a front portion of the bottom surface of the groove portion  49 . A shaft portion  52  is formed between the guide walls  50 . Latch receiving portions  53  protrude forward from the guide walls  50  positioned at both end portions, respectively. A first latch recessed portion  54  and a second latch recessed portion  55  are formed in the latch receiving portions  53 . Plate-like abutting receiving portions  56  protrude downward from both end portions, respectively. A lower end portion of each of the abutting receiving portions  56  includes an inclination portion  56   a  which gradually protrudes downward, along the direction of facing toward the rear side. 
     In the movement member  4  of this configuration, when a substrate  17  is inserted into an insertion recessed portion  6  of a housing  1  as illustrated in  FIG. 13 , the inclination portion  56   a  is pressed by a leading end edge of the substrate  17 . This makes the movement member  4  rotate from a horizontal position to a standing-up position as illustrated in  FIG. 14 . At this time, like the first embodiment, a latching position of a latch protrusion portion  38  of a latching member  3  is switched from a second latch recessed portion  55  to a first latch recessed portion  54 , and the movement member  4  is position-determined in the standing-up position. 
     If the substrate  17  is pushed inward further, the substrate  17  comes into contact with an abutting receiving portion  57  of the latching member  3  and an elastic portion  36  elastically deforms. As a result, the latch protrusion portion  38  is unlatched from the first latch recessed portion  54 . Accordingly, the movement member  4  rotates from the standing-up position to the horizontal position by the elastic force of a first arm portion  23  of a contact point member  2  which is exerted on a shaft portion  52 . Therefore, a contact point portion  28  which protrudes into the insertion recessed portion  6  comes into pressure contact with a conductive portion of the substrate  17 , making an electrical connection. The user can recognize visually that the movement member  4  rotates from the horizontal position to the standing-up position, and then rotates again to the horizontal position. By recognizing this movement visually, it is possible to identify that the substrate  17  is inserted up to a proper position and an electrical connection between the contact point portion  28  of the contact point member  2  and the conductive portion of the substrate  17  is made, from the outside of the housing  1 . At this time, the abutting receiving portion  56  of the movement member  4  is latched onto the latching notch portion  18  of the substrate  17  so that the substrate  17  may be prevented from being slip off the housing  1 . 
     There has thus been shown and described a connector which fulfills all the objects and advantages sought therefore.
