Description of the Related Art For example, when a peripheral device is connected to a computer, a cable is extended from the peripheral device, a connector is connected to the end of the cable, and the connector is connected to a connector exposed outside the computer. I have to do it. This type of connector generally employs a structure in which male and female are combined and connected to each other, and as shown in FIGS. 4 to 6, a male connector 1 is provided with a large number of pin heads 2 and a female connector 6 is provided. Are provided with a number of contacts 7 (see FIG. 6) into which the pin heads 2 are inserted and come into contact with the pin heads 2. When the male connector 1 and the female connector 6 are connected, the pin heads 2 and the contacts 7 are connected to each other. They are connected. In addition,
A housing 3 is provided around the pin head 2 of the male connector 1, and a housing 8 is provided around the contacts 7 of the female connector.
When the housing 3 is combined with the housing 8, the housing 8 is positioned inside the housing 3.
To fit.

However, when the connectors 1 and 6 are connected, if the male connector 1 and the female connector 6 are in a relatively inclined state, the pin head 2 contacts the contact 7 while being inclined. The pin head 2 may be bent or broken. In particular, in recent years, the functions of peripheral devices have increased, and various signals have been exchanged with a computer. Therefore, the number of pin heads 2 has increased, and the pitch of the pin heads 2 has decreased. It may be bent or broken.

In view of such inconvenience, as a structure for preventing bending or breakage of the pin head 2, there is, for example, a structure of a connector connecting portion of a board described in Japanese Patent Application Laid-Open No. 4-112264. The structure of the connection portion is such that an I / O pin skirt formed of an insulating material on a substrate and having a pin insertion hole through which each I / O pin of an I / O pin matrix corresponding to the connector is inserted is vertically moved. Movable and I / O
A spring for urging the I / O pin skirt upward is mounted between the pin skirt and the surface of the substrate, and is held near the free end of the I / O pin when the connector is not mounted. .

[0005]

However, in the above-mentioned conventional connector connection structure, since the insertion holes of the pin skirt are inserted into the respective I / O pins of the I / O pin matrix, the connector is mounted. When doing, I /
Unless it is inserted straight in the direction of the O pin, it cannot be connected. That is, when the connector is in an inclined state, the insertion force acts on the pin skirt from an oblique direction, and the insertion hole of the pin skirt comes into contact with the I / O pin and acts as a reaction force for preventing insertion of the connector. Will do. For this reason, the connection of the connector cannot be performed smoothly, and the connection work may be complicated. Also,
Since a pin skirt having an insertion hole through which all the I / O pins are inserted is required, the processing of the pin skirt is complicated and the structure is complicated.

A housing 22 for protecting the contact 21 is provided around the contact 21, and the tip of the housing 22 is made substantially coincident with the tip of the contact 21 or slightly protrudes from the tip of the contact 21. is there. As shown in FIG. 1, a flange portion 23 is formed at an end portion of the housing 22 by being bent outward.

Outside the housing 22 of the female connector 20,
A guide frame 30 substantially similar to the housing 22 is provided. This guide frame 30 is
Is formed so as to be slidable by being guided by the distal end of the flange portion 23, and has flange portions directed inward at both ends. A base flange portion 31 of the guide frame 30, which is located on the female connector 20 side, is located closer to the female connector 20 than the flange portion 23, and is guided by engaging with the flange portion 23. The frame 30 is prevented from falling off the housing 22. A return spring 35 as an urging means composed of a compression coil spring is interposed between the inner side surface of the distal end flange portion 32 of the guide frame 30 and the outer side surface of the flange portion 23.

The operation of the embodiment of the connecting portion structure of the connector according to the present invention configured as described above will be described below.
