The plug connector 2 is mounted on the printed wiring board 10 in this example. The plug contact 4 penetrates the small hole 12 formed in the printed wiring board 10 and is connected to a conductor pattern (not shown) by, for example, soldering.

The printed wiring board 10 is, for example, a back wiring board provided on the back side of the apparatus casing for connecting a plurality of printed wiring board units to each other. In this case, the jack connector 14 is provided on each printed wiring board. Mounted on the unit.

The jack connector 14 has jack contacts 16 (see FIG. 3) made of a plurality of conductors corresponding to the respective plug contacts 4, and when the jack connector 14 is attached to the plug connector 2, 4 and the jack contact 16 are electrically connected.

The base 6 integrally has a hollow rectangular parallelepiped guide portion 8 for guiding the jack connector 14 when the jack connector 14 is attached and detached. An insulating plate 18 having an outer shape along the inner peripheral wall surface of the guide portion 8 is housed inside the guide portion 8.

The insulating plate 18 has a hole 20 through which each of the plug contacts 4 penetrates, and an opening 24 through which a column 22 erected on the base 6 penetrates. The column 22 is parallel to the plug contact 4, and is formed integrally with the base 6, for example.

The insulating plate 18 has the plug contact 4 with the hole 2
The jack connector 14 can be moved in the attaching / detaching direction within a range in which the state of penetrating 0 is maintained. In order to determine this range, a ring member 26 having a diameter larger than that of the opening 24 is fixed near the tip of the column 22.

Further, there is provided a means for urging the insulating plate 18 in the direction away from the base 6 in order to cause the insulating plate 18 to follow the jack connector 14 in accordance with the detaching / attaching operation of the jack connector 14. This means is, for example, a coil spring 28 provided between the base 6 and the insulating plate 18 as shown. The coil spring 28 is wrapped around the column 22 to minimize its storage space.

As shown in FIG. 3, a Y-branch 30 is formed at an end of the jack contact 16 located inside the main body of the jack connector 14, and the other end of the jack contact 16 has a contour line in the drawing. Is connected to the printed wiring board unit 32. The Y-branch 30 is for sandwiching the plug contact 4, and a protrusion 30A is formed inward at the tip thereof.

A taper portion 34 is formed on the end surface of the jack connector 14 on the plug connector 2 side so as to easily guide the tip of the plug contact 4 to the Y branch 30.

Next, a method of using this connector will be described with reference to FIG. As shown, jack connector 14
Is disconnected from the plug connector 2, the insulating plate 1
8 receives the elastic force of the coil spring 28 and is in contact with the ring member 26. With the conventional connector structure,
When the jack connector is detached, the plug contact is exposed, and this is often inclined by an external force. However, in the present embodiment, when the jack connector 14 is detached, the vicinity of the tip of the plug contact 4 is detected. Exists in the hole 20 of the insulating plate 18, so that even if the plug contact 4 is long, it is difficult to tilt.

The jack connector 14 is replaced with the plug connector 2
When the plug contact 4 is attached to the jack contact 16, the insulating plate 18 moves leftward in FIG. Connection is made.

At this time, the urging force of the compressed coil spring 28 acts in the direction of removing the jack connector 14, but friction occurs between the plug contact 4 and the protrusion 30A of the Y branch 30. Since a plurality of sets of plug contacts 4 and jack contacts 16 are provided,
The state where the jack connector 14 is attached to the plug connector 2 is stably maintained.

When the number of sets of the plug contact 4 and the jack contact 16 is small and a sufficient frictional force against the biasing force of the coil spring 28 cannot be obtained,
Although not shown, lock means for maintaining the mounted state of the jack connector 14 may be provided.

In this embodiment, since the base portion 6 integrally has the guide portion 8 having a shape corresponding to the shape of the jack connector 14, when the jack connector 14 is attached to the plug connector 2, the jack connector 14 is attached. It is possible to prevent the housing 14 and the like from coming into contact with the tip of the plug contact 4 at an undesired angle, and prevent the plug contact 4 from being deformed or tilted, including bending.

FIG. 4 is a sectional view of a plug connector showing another example of the plug contact. This embodiment is characterized in that the plug contact 4 has a large diameter portion 4A at a position corresponding to the insulating plate 18 when the jack connector is detached.

The maximum outer diameter of the large diameter portion 4A is the hole 2 of the insulating plate 18.
