Description

  The present invention relates to an upright connector that is mounted on a board and that is engaged and disengaged with a mating connector perpendicular to the board.

  There are various types of connectors, such as a mating type in which the mating connector and housing are fitted together to contact each other's contacts, or an IC card on which information is recorded and the surface of the IC card A card receiving type or the like in which a flat contact provided on the upper surface and a self-contact are brought into contact with each other is known. In addition to the wire connection type in which the contact is connected to the electric wire, these connectors are known in the board connection type in which the housing is fixed on the substrate and the contact is connected to the wiring pattern on the substrate. Yes.

In addition, the board connection type connector includes a horizontal type (angle type) in which the engagement / disengagement direction with the counterpart connector is parallel to the board, and a vertical type (straight type) perpendicular to the board. In the board connection type connector, the housing is mounted directly on the board, but the mounting is done by inserting the protrusion formed on the lower surface of the housing into the positioning hole formed on the board and then the position near the board of the housing.

  However, in the case of the board connection type connector, even if the housing is fixed on the board by the fixing bracket as described above, the housing is a standing type in which the housing is arranged so as to extend perpendicularly to the board. However, the amount of deformation when subjected to an external load such as bending or twisting due to "twisting" or "twisting" when engaging / disengaging with the mating connector is larger than that of the horizontal type in which the housing is arranged along the board Become. For this reason, in order to prevent the housing from being excessively deformed in the standing type connector, there is a problem in that the housing must be increased in size, and the apparatus including the connector is increased in size.

  The present invention has been made in view of such problems, and even if an external load due to "twisting" or "twisting" acts when engaging / disengaging with the mating connector without increasing the size of the housing, the deformation is excessive. It is an object of the present invention to provide an upright connector having a configuration that does not become.

  The vertical connector according to the present invention is mounted on a board, and the vertical connector (for example, implementation) in which the engagement / disengagement direction with the counterpart connector (for example, the plug-type connector 110 in the embodiment) is perpendicular to the board. In the receptacle type connector 10) in the embodiment, a housing (for example, the receptacle housing 20 in the embodiment) having a coupling portion (for example, the plug portion insertion port 21 in the embodiment) on the side opposite to the substrate, with the mating connector And two fixing brackets which are attached to both side walls located opposite to each other in the longitudinal direction of the housing as viewed from the connecting portion side and fix the housing to the substrate, and each fixing bracket is provided on the side wall of the housing. In the U-shaped portion formed at the end while extending outward in the direction opposite to the substrate, the coupling of the housing And it covers the vicinity of the position.

  In the upright connector according to the present invention, the fixing bracket that is attached to each side wall facing the long dimension direction of the housing as viewed from the coupling portion side with the mating connector and fixes the housing to the substrate is provided on the housing. The outside of the side wall extends in the direction opposite to the substrate, and a U-shaped portion formed at the end covers the position in the vicinity of the coupling portion of the housing. For this reason, even if an external load such as bending or twisting due to “twisting” or “twisting” acts when engaging / disengaging with the mating connector, the position near the coupling portion of the housing is supported by the U-shaped portion of the fixing bracket. As a result, the amount of deformation of the housing can be kept small. In addition, since such a configuration does not involve an increase in the size of the housing, it is possible to prevent an increase in the size of the device provided with the upright connector (or downsizing the device).

This is done by soldering in place.

  FIG. 7 shows a plug connector 110 which is a mating connector used in combination with the receptacle connector 10. The plug-type connector 110 is held by the plug housing 20, a plug housing 20 that is provided so as to extend horizontally so as to correspond to the width direction of the receptacle-type connector 10, a press-contact cover 130 coupled to the plug housing 20, and the plug housing 20. A plurality of plug-side contacts 140 (here, the same number as the number of receptacle-side contacts 30), and a plurality of plug-side contacts 140 that are pressed against each plug-side contact 140 and held by the plug housing 20 and the pressure-contact cover 130 (here, plug-side contacts). The number of contacts 140 is the same as the number of contacts 140 and 10). The plug housing 20 and the pressure contact cover 130 are made of an electrically insulating material such as resin.

  The plug housing 120 is formed with a projecting plug portion 121 that is inserted into the receiving space S of the receptacle-type connector 10, and on one surface side (corresponding to the lower surface side in FIG. 7) of the plug portion 121, A plurality of locking projections 121 a extending substantially orthogonal to the direction orthogonal to this surface, that is, the engagement / disengagement direction of the plug housing 120 and the receptacle housing 20 are provided.

  Each plug-side contact 140 is made of a conductive material such as a metal and has a bent shape as shown in FIGS. 8 and 13, and is on the other surface side of the plug portion 121 (on the upper surface side in FIG. 7). A contact portion 141 extending along the wire) and a wire connection portion 142 to which the electric wire 150 is connected. As shown in FIGS. 8 and 9, the wire connection portion 142 is provided with a pressure contact groove 143 for press-contacting the wire 150. When the wire is pressed against the pressure contact groove 143 (see FIG. 9A), the wire 150 The insulation coating 152 is cut by the inner edge of the pressure contact groove 143 so that the core 151 comes into contact with the pressure contact groove 143 (see FIG. 9B).

  In order to press-contact the electric wire 150 in the press-contact groove 143 of the plug-side contact 140, first, as shown in FIG. 10A, all the ten electric wires 150 are placed on the press-contact groove 143 in a parallel state. . At this time, the electric wires 150 are aligned and held by a jig 100 prepared as a separate member from the plug-type connector 110. When the electric wire 150 is thus placed on the pressure contact groove 143, the pressure contact cover 130 is pressed against the plug housing 20. At this time, the left and right side portions 131 of the pressure contact cover 130 enter the left and right pressure contact cover holding spaces 122 of the plug housing 120 from above, and the locking protrusions 132 provided on the left and right side portions 131 of the pressure contact cover 130 are plugged. It is made to fit in the hollow (not shown) provided in the left-right side part of the housing 20. As shown in FIG. As a result, the pressure contact cover 130 is temporarily joined to the plug housing 20 (see FIG. 10B).

  When the temporary coupling of the pressure contact cover 130 to the plug housing 20 is finished, the pressure contact cover 130 is pushed from above the plug housing 20. As a result, a plurality of press-fitting protrusions (not shown) provided on the press-contact cover 130 are press-fitted into press-fit holes (not shown) formed in the plug housing 120, and the press-contact cover 130 and the plug housing 120 are firmly coupled. At the same time, each electric wire 150 is pressed into the press contact groove 143 by the lower surface of the press contact cover 130. Thereby, the insulation coating 152 of each electric wire 150 is cut and pressed into the press contact groove 143 (see FIG. 10C).

  When the plug-type connector 110 having such a configuration is inserted from the plug part insertion port 21 of the receptacle-type connector 10 with the plug part 121 facing downward (see FIG. 11), the plug part 121 has its plug-side contact 140. As a result, the contact 40 of the receptacle-type connector 10 enters the inside of the receptacle-type connector 10, that is, the receiving space S, while being pushed away (elastically deformed). A plurality (three in this case) of locking projections 121a formed on the plug part 121 are formed on the rear wall 25 of the receptacle type connector 10 (here, the same number as the number of the locking projections 121a is three). A click feeling is obtained when the engagement recess 25a is inserted (engaged) from the inside of the rear wall 25, and the plug portion 121 is locked in the receptacle connector 10, so that the plug housing 120 and the receptacle housing 20 are fitted. Match. Thereby, the plug-type connector 110 and the receptacle-type connector 10 are in a coupled state (see FIGS. 12 and 13). In this state, the plug-side contact 140 and the receptacle-side contact 30 are in contact with each other (see FIG. 13), and both the connectors 110 and 10 are in an electrically connected state, and signal transmission between the both connectors 110 and 10 is performed. Is possible.

  Further, in order to separate the connectors 110 and 10 from the state in which the connectors 110 and 10 are coupled in this way, the plug-type connector 110 may be pulled away from the receptacle-type connector 10. As a result, each locking projection 121 a formed on the plug portion 121 of the plug-type connector 110 is detached from the locking recess 25 a formed on the rear wall 25 of the receptacle-type connector 10. And the plug side contact 140 and the receptacle side contact 30 will be in a non-contact state, and the receptacle side contact 30 will return to the original state (refer FIG. 4) from the state which was elastically deformed. Note that each locking projection 121a formed on the plug portion 121 of the plug-type connector 110 has a receptacle type so that the locking projection 25a formed on the rear wall 25 of the receptacle-type connector 10 can be easily engaged and disengaged. Tapered surfaces 121b and 121c that are inclined in the direction of engagement / disengagement with the connector 10 are provided (see FIG. 13).

  As described above, in the receptacle type connector 10 according to the present embodiment, the receptacle housing 20 is viewed in the long dimension direction (width direction) when viewed from the side of the connecting portion (plug portion insertion port 21) with the plug type connector 110 that is the counterpart connector. Fixing brackets 40 which are attached to the opposite side walls 26 and 26 and fix the receptacle housing 20 to the substrate 50 are arranged so that the outside of the side wall 26 of the receptacle housing 20 is in the direction opposite to the substrate 50 (upward). While extending, the U-shaped portion 42 formed at the end portion (upper end portion) covers the vicinity of the coupling portion (plug portion insertion port 21) of the receptacle housing 20. For this reason, even if an external load such as bending or twisting due to “twisting” or “twisting” acts when engaging / disengaging with the plug-type connector 110, the position near the coupling portion (plug portion insertion port 21) of the receptacle housing 20 is Since it is supported by the U-shaped portion 42 of the fixing bracket 40, the deformation amount of the entire receptacle housing 20 can be kept small. Moreover, since such a configuration does not involve an increase in the size of the receptacle housing 20, it is possible to prevent an increase in the size of the device including the receptacle connector 10 or to reduce the size of the device.
