Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a contact holding structure, and more particularly to a contact holding structure for a plug-in type unit.
The present invention relates to a structure for holding a contact with a cable of a piece connector.

[0002]

2. Description of the Related Art Conventionally, as a contact holding structure of this kind, there is one as shown in FIG. That is, FIG.
1A and 1B, the contact holding structure is a connector 12 fixed to a unit 11 by a fixing screw 14.
When the contact 13 is press-fitted, an insulating film 15 is attached to the contact 13 in advance, and the contact 13 is inserted into a gap 16 between the connector 12 and the contact 13 so that the inclination of the contact 13 is reduced.
9 is prevented.

[0003]

In the conventional contact holding structure described above, it takes time to mount the insulating film 15 and there is a possibility that the mounting may be forgotten. Furthermore, since the insulating film 15 itself is soft, when the cable 17 of the contact is bent and enters the connector 12, the reaction force of the cable 17 becomes stronger than the contact holding force of the insulating film 15. 18 has a large inclination 19 in the direction of the arrow, which is a factor of causing a poor fitting with the connector 12 on the motherboard side.

[0004]

According to the present invention, there is provided a contact holding structure comprising: a connector fixed to a unit to form a plug-in structure; a contact press-fitted to the connector;
A guide block having a shape capable of being press-fitted and fixed to the contact insertion side of the connector, and having a hole through which an external conductor of the contact can be closely fitted and inserted, and a slit through which a cable of the contact can pass. ,
The guide block is divided according to the shape of the connector.

[0005]

Next, an embodiment of the present invention will be described with reference to the drawings. 1 (a) and 1 (b) are an exploded perspective view and a sectional view, respectively, of an embodiment of the present invention.

In this embodiment, a connector 2 which is fixed to a unit 1 and has a plug-in structure, a contact 3 which is press-fitted to the connector 2, and a contact 3 which is press-fittable and fixable on the contact insertion side of the connector 2. And a guide block 4 having a slit 5 through which a cable 7 of the contact 3 can pass.

In this embodiment having such a configuration, FIG.
As shown in (a) and (b), first, a contact 3 is press-fitted and connected to a connector 2 soldered and fixed to a unit 1. Since the guide block 4 has the slit 5 through which the cable 7 of the contact 3 can pass, the guide block 4 is press-fitted and fixed to the connector 2 after passing the cable 7 through the slit 5. At this time, guide block 4
Since the contact insertion hole 6 and the contact 3 are fitted and inserted in a close contact state with no gap, and the guide block 4 has a sufficient contact length L, the cable 7 bends and enters the connector 2. In this case, the inclination 9 of the tip 8 of the contact 3 is minimized. Therefore, it is possible to suppress a poor connection between the connector 2 and the contact 3.

In this embodiment, the guide block 4 is illustrated as being divided into two parts. However, the guide block 4 may be divided into two parts or three or more according to the shape of the connector 2. You may. Also, the shape of the press-fit fixing portion of the guide block 4 to the connector 2 is determined to be an arbitrary shape corresponding to the shape of the connector 2.

[0009]

As described above, according to the present invention, a connector is provided with a guide block having a hole through which the external conductor of the contact can be closely inserted and a slit through which the contact cable can pass, on the contact insertion side of the plug-in connector. By press-fitting and fixing, in a plug-in mounting type device using a two-piece connector including a contact, the inclination of the contact and the connector main body can be easily and reliably prevented, and a fitting failure is eliminated, so that reliability and maintenance of the device are improved. Performance can be improved.
