Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a male and female electrical connector for performing electrical conduction in a connector or the like.

(Prior Art) Conventional male and female electrical connectors include those shown in FIGS. 4 and 5, for example.

FIG. 4 is a partially cutaway side view in a connected state, and FIG. 5 is a perspective view in a detached state.

The male and female electrical connectors comprise a female electrical connector 1 and a male electrical connector 3. The female electrical connector 1 is connected to the electric wire 5 by an insulating caulking portion 7 and a conductor caulking portion 9 and has an electric contact portion 11 at a distal end portion. The electric contact portion 11 is formed, for example, in a rectangular hollow cross section, and has a spring portion 13 folded inside.

The male electrical connector 3 is connected to the electric wire 15 via an insulating caulking portion 17 and a conductor caulking portion 19 like the female electrical connector 1, and has a plate-shaped insertion portion 21 at its tip. It has.

Although not shown, the female electric connector 1 is accommodated in a terminal accommodating chamber of the male connector, and the male electric connector 3 is accommodated in a terminal accommodating chamber of the female connector. When the male connector is connected to the female connector, the insertion portion 21 of the male electrical connector 3 is inserted into the electrical contact portion 11 of the female electrical connector 1, and the female electrical connector 1 and the male electrical connector are connected. 3 is electrically conducted. At this time, the urging force of the spring portion 13 is
Of the female electrical connector 1 and the male electrical connector 3 so as to maintain electrical continuity between the female electrical connector 1 and the male electrical connector 3.

(Problems to be solved by the invention) However, in the male electrical connector having such a structure, the urging force of the spring portion 13 becomes a resistance at the time of insertion, so that a large insertion force is required, and the insertion work becomes complicated. Had become. In particular, in a connector having multi-pole (for example, 10-pole) male and female electrical connectors, assuming that the insertion force of one male and female electrical connector is 3 kgf at the initial stage, 3 kgf × 10 = 30 kg.
f insertion force was required, and there was a risk that manual insertion would be difficult.

In addition, if the contact is caused by the spring portion 13, an insulator may be generated at the contact portion due to vibration, an oxide film or the like may be generated, and stable contact may not be obtained.

On the other hand, there is a case in which a liquid metal is inserted between the connection terminals to achieve conduction (Japanese Patent Application Laid-Open Nos. 58-218777 and 61-12407).
1). In the case of such a structure, since the insertion of the insertion portion is performed for the liquid metal, the problem caused by the contact with the spring portion can be improved. However, since the conductive substance is the liquid metal. In consideration of leakage, the insertion direction is limited to the up and down directions. In addition, in order to limit the insertion direction, the liquid metal must be sealed and held, which makes the structure complicated and makes it difficult to produce a small, multi-pole connector.

So the idea is easy to plug in, simple in construction,
It is an object of the present invention to provide a male and female electrical connector capable of obtaining stable electrical contact.

[Structure of the invention] (Means for solving the problem) In order to solve the above-mentioned problem, the invention is directed to inserting the male electrical connector from the insertion port of the female connector into the insertion portion of the female electrical connector. A male / female electrical connector for inserting the insertion portion of the connector to conduct electrical connection between the two, wherein the insertion portion is sized to loosely fit the insertion portion, and a conductive viscous material is provided in the insertion portion. A body having a cross-sectional shape corresponding to the insertion port formed at the base of the insertion portion by inserting the insertion portion into the electroconductive viscous body and conducting conduction between the two via the electroconductive viscous body. And it is characterized by having an inclined surface portion which comes into contact with the insertion port.

(Operation) According to the above configuration, since the insertion portion of the male electrical connector is inserted into the conductive viscous body of the inserted portion of the female electrical connector, the insertion force can be reduced.

After the insertion, the connection between the inserted portion and the inserted portion is performed through the conductive viscous body.

(Example) Hereinafter, an example of the present invention will be described.

FIG. 1 is a side view of a male and female electrical connector according to an embodiment of the present invention, in which a part of the female electrical connector 1 is cut away, and FIG. 2 is a perspective view of the same. The basic configuration of the male and female electrical connectors of this embodiment is substantially the same as that described with reference to FIGS. 4 and 5, and the same components are denoted by the same reference numerals and description thereof will be omitted.

On the other hand, in the male and female electrical connector according to the embodiment of the present invention,
The inserted portion 23 of the female electrical connector 1 is formed, for example, in a hollow circular cross section, and the male electrical connector 3 inserted into the inserted portion 23 is provided.
The insertion part 25 is formed in a correspondingly circular cross section. The insertion portion 23 is formed to have a size that allows the insertion portion 25 to be loosely fitted. Specifically, the radius of the inner peripheral diameter of the inserted portion 23 is larger by 10 to 30% than the radius of the outer peripheral diameter of the inserted portion 25, so that a gap is formed between the two.

The base 27 of the inserted portion 23 is connected to the conductor caulking portion 9 with a taper, and the tip 29 of the inserted portion 25 is tapered.

The outer diameter of the base 31 of the insertion portion 25 is formed to be larger than the inner diameter of the insertion portion 23, and a taper at the front end in the insertion direction as an inclined surface portion that comes into contact with the insertion opening of the insertion portion 23. Has a part 33,
The rear end is connected to the conductor caulking portion 19 side.

When the insertion section 25 is inserted into the insertion section 23, a conductive viscous body 35 is interposed between the two, and electrical conduction between them is performed.
The conductive viscous body 35 is a conductive paste obtained by mixing, for example, a modified polyolefin resin as a binder, for example, a liquid metal such as gallium Ga, and has a characteristic value of 200 to 300 poise at room temperature and a specific resistance of 1 ×. 10 ^-4 to 10
^-5 Ωcm.

Next, insertion of such male and female electrical connectors will be described.

At the time of insertion, the conductive viscous body 35 is previously injected into the inserted portion 23 of the female electrical connector 1. This injection extends to about half of the length direction of the inserted portion 23. Then, the insertion portion 25 of the male electrical connector 3 is inserted into the conductive viscous body 35 of the insertion target portion 23 by joining a male connector and a female connector (not shown). After the insertion section 25 is inserted into the insertion section 23, the tapered section 33 of the insertion section 25 abuts on the insertion port at the tip of the insertion section 23 to close it, and the conductive viscous body 35 Prevent leakage. In addition, due to the insertion of the insertion portion 25, the conductive viscous body 35 partially moves to the base portion 27 side of the insertion target portion 23, but since the base portion 27 is narrowed with a taper, leakage from the base portion 27 also occurs. Can be prevented.

And the resistance at the time of such insertion is the conductive viscous material 35
, The insertion force is much smaller than in the case where a spring portion is used as in the related art. Therefore, even with a multi-pole connector, it is possible to insert the connector very easily with a small force. The tapered tip 29 of the insertion portion 25 also contributes to a reduction in insertion force. After the insertion, the inserted state is maintained by the viscous force of the conductive viscous body 35, so that the conductive viscous body 35 does not easily come off. In addition, a part of the tapered portion 33 of the insertion portion 25 is
23 is slightly fitted into the tip, and mutual positioning is performed to stabilize the insertion state. After the insertion, the presence of the tapered portion 33 of the insertion portion 25 and the base 27 of the insertion portion 23 causes the conductive viscous body 35 to be inserted into the insertion portion 23.
Although it is in a form sealed inside, it is not necessary to particularly seal, so that it is possible to reduce the size.

Further, since there is no generation of an insulator or an oxide film at the contact portion due to vibration caused by the contact using the spring portion, stable electrical contact can be obtained.

 FIG. 3 shows a perspective view according to another embodiment of the present invention.

The same structures as those in the above-described embodiment are denoted by the same reference numerals, and duplicate description will be omitted.

In this embodiment, the inserted portion 37 is formed in a hollow rectangular cross section,
The insertion portion 39 has a plate shape corresponding to this. The base 41 of the insertion portion 39 is formed larger than the insertion portion 37, and has a slope portion 43 on the front side in the insertion direction as an inclined surface portion that comes into contact with the insertion port of the insertion portion 37. . Therefore, in this embodiment, substantially the same operation and effect as those of the above embodiment can be obtained,
Since the plate 39 has a plate shape, the insertion force can be further reduced. In addition, the slope portion 43 has the same function as the tapered portion 33, and is positioned by being slightly fitted to the tip of the insertion portion 37, so that the plate-shaped insertion portion 39 is properly formed in the insertion portion 37. Can be set in the position.

The present invention is not limited to the above embodiment. For example, a paste obtained by mixing a conductive powder with a base material serving as a binder as a conductive viscous material can be used.

[Effects of the invention] As is clear from the above, according to the configuration of the invention,
The insertion force is significantly reduced because the viscous resistance of the conductive viscous body is mainly used, and the insertion work is extremely easy.

Further, unlike the case where liquid metal or the like is used, there is no need for sealing, and a small and simple structure can be obtained.

Furthermore, there is no spring contact, no insulator is generated at the contact due to vibration, and no oxide film or the like is generated.
A stable contact state is obtained.

After the insertion is conducted, the inclined surface of the base of the insertion portion comes into contact with the insertion port of the insertion target portion, thereby reliably preventing leakage of the conductive viscous material. In addition, the insertion portion corresponding to the insertion target portion is positioned by the contact of the inclined surface portion with the insertion port, and the insertion state is stabilized.
