Description

  The present invention relates to a connector, and more particularly to a connector that allows a plug-type connector to be smoothly inserted and fitted into a plug insertion space of a socket-type connector.

  2. Description of the Related Art Conventionally, many connector structures in which a socket-type connector and a plug-type connector are combined with each other are known (see, for example, Patent Document 1).

  In general, the structure of a connector that is a combination of a socket type connector and a plug type connector is shown in FIG. 6, in which a plug insertion in which an insertion port 2 is opened on the front surface of the socket type connector 1 is provided. A space 3 is provided, and a plug-type connector 4 is inserted and fitted into the plug insertion space 3 from the insertion port 2. In this connector structure, the diameter of the insertion port 2 in the socket-type connector 1 and the size of the plug portion 5 in the plug-type connector 4 are formed to be substantially the same size.

Therefore, if the center axis S1 of the socket-type connector 1 and the center axis S2 of the connector 4 do not coincide with each other and the center axes S1 and S2 are shifted as shown in FIG. In the portion indicated by the symbol B in the figure, the front surface of the tip portion of the plug portion 5 of the plug-type connector 4 collides with the front surface of the peripheral edge portion of the insertion port 2 of the socket-type connector 1, thereby causing a problem that smooth insertion is hindered. To do. Further, even when the orientation (angle) of the center axis S1 of the socket-type connector 1 and the center axis S2 of the connector 4 is deviated from each other, there is a problem that the tip portions collide with each other and the insertion operation is not performed smoothly. It was.
JP-A-8-130052).

  As described above, the structure of the conventional connector is a plug type when the insertion and fitting are performed in a state where the position and orientation of the center axis S1 of the socket type connector 1 and the center axis S2 of the plug type connector are shifted. The front surface of the tip of the plug portion 5 in the connector 4 collides with the front surface of the peripheral edge of the insertion port 2 in the socket type connector 1, so that the plug type connector 4 cannot be inserted. For this reason, since it must be inserted and fitted in a state where the position and orientation of the central axis S1 of the socket-type connector 1 and the central axis S2 of the connector 4 are matched, the insertion work takes time, especially in a narrow place, In addition, when performing work by groping, there is a problem that the work cannot be performed smoothly and a lot of time is spent. Also, if the connectors are forcibly pressed against each other in a state where the tip portions do not match, there is a possibility that the tip portions are damaged.

  Therefore, the plug type connector should be able to be smoothly inserted and fitted into the plug insertion space of the socket type connector so as to improve workability and eliminate damage such as damage caused at the time of insertion fitting. A technical problem arises, and the present invention aims to solve this problem.

The present invention has been proposed to achieve the above object, and the invention according to claim 1 is a metal shield case formed in a rectangular tube shape by providing an insertion opening on the front side, and the shield case. An insulating base portion attached to the rear surface side of the shield case and having a flat plate portion projecting from the rear to the front in a plug insertion space surrounded by A plurality of conductive contacts disposed on the insulating flat plate portion, the terminal portion on the other end side being drawn out to the outside of the rear portion of the base, and plug-type from the insertion port into the plug insertion space. In a socket-type connector into which a connector is inserted and fitted, an inclined surface that expands outward in order to guide the plug-type connector into the plug insertion space at the insertion port of the shield case. Provided To provide a connector.

  According to this configuration, even if the position and orientation of the central axis of the plug-type connector are slightly deviated from the position and orientation of the central axis of the socket-type connector, the plug-type connector is inserted into the insertion port. When the plug-type connector is advanced, the tip end portion of the plug-type connector collides with an inclined surface provided in the insertion port, and is then guided toward the plug insertion space by the inclination of the inclined surface. It is inserted and fitted into the insertion space.

  A second aspect of the present invention provides the connector according to the first aspect, wherein the inclined surface is provided on each side of the substantially rectangular insertion port.

  According to this structure, since the inclined surface which spreads outward is provided on each side of the insertion port formed in the rectangular tube shape, the position and orientation of the central axis in the plug-type connector are up, down, left and right. Regardless of the direction, when the plug-type connector is inserted, the tip of the plug-type connector comes into contact with the inclined surface and is smoothly inserted into the plug insertion space.

  According to a third aspect of the present invention, in the first or second aspect, the inclined surface is outward from 55 degrees to 65 degrees with respect to each side surface of the shield case forming the plug insertion space. Provide a connector that is inclined toward.

  According to this configuration, even when the distal end portion of the plug-type connector collides with the inclined surface, the angle 55 is an optimum angle for guiding the collided distal end portion of the connector toward the plug insertion space. Since it is inclined so as to expand outward at a degree of 65 degrees to 65 degrees, the distal end portion of the plug-type connector is smoothly inserted into the plug insertion space.

  According to the first aspect of the present invention, even if the position and orientation of the center axis of the plug-type connector are slightly deviated from the position and orientation of the center axis of the socket-type connector, The plug-type connector is in contact with the inclined surface provided in the insertion port, but is then guided toward the plug insertion space by the inclination of the inclined surface, Since it can be inserted and fitted into the plug insertion space, workability can be improved, and damage to the tip portions of the connectors can be reduced as much as possible.

  The invention according to claim 2 is provided with an inclined surface on each side of the insertion port formed in a rectangular tube shape, and the position and orientation of the central axis of the plug-type connector are shifted in any of the vertical and horizontal directions. However, when the plug-type connector is inserted, the tip of the plug-type connector comes into contact with the inclined surface, and thereafter, the plug-type connector can be smoothly inserted into the plug insertion space. In addition to the effect of the invention described in item 1, it can further contribute to the improvement of workability.

According to a third aspect of the present invention, when the distal end portion of the plug-type connector comes into contact with the inclined surface, the angle is optimal for guiding the distal end portion of the connector toward the plug insertion space. It is inclined so as to expand outward at a degree of 65 to 65 degrees, and when the distal end portion of the plug-type connector comes into contact with the inclined surface of the image, it is smoothly inserted into the plug insertion space. Thus, in addition to the effect of the invention according to claim 1 or 2, further improvement in workability can be expected.

  In order to achieve the purpose of smoothly inserting and fitting the plug type connector into the plug insertion space of the socket type connector, improving the workability and eliminating the damage that can be caused during the insertion and fitting.
