Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a push-pull type separation connector capable of separating electrical connections by separating the connectors by a very simple operation.

[0002]

2. Description of the Related Art Separate connectors have been used for the purpose of disconnecting electrical connection with a rocket or an artificial satellite at the time of launch or flight of the rocket or an artificial satellite. FIG. 5 is a sectional view showing a conventional separation connector.

[0005] A conventional detachable connector comprises a female connector 112 and a male connector 111 as shown in FIG. 5, and in FIG.
11 shows a connected state. Female connector 1
In 12, a plurality of pin contacts 101 electrically connected to respective ends of the plurality of conductive wires 110 are embedded in parallel in a female connector shell 103 made of a non-conductive material.
Each pin contact 101 protrudes from one surface of the female connector shell 103.

In the male connector 111, a plurality of socket contacts 107 are provided in the male connector shell 102.
Are embedded in parallel corresponding to the respective pin contacts 101 of the female connector 112. A socket port of each socket contact 107 is provided on one surface of the male connector shell 102. Inside each socket contact 107, a pair of plate-shaped springs 108 are arranged with their respective bent and expanded surfaces facing each other. The pair of springs 108 are electrically connected to the conductor 109.

[0005] Female connector 112 and male connector 1
11 is connected to the female connector 112.
Of the male connector 111 on the socket contact 107 side, and presses the female connector 112 and the male connector 111 to place the pin contact 101 inside the socket contact 107. Insert At this time, the pin contact 101 enters between the pair of springs 108 arranged in the socket contact 107, and the pin contact 101 pushes apart the pair of springs 108.

Therefore, when the female connector 112 and the male connector 111 are connected, the elastic force of the spring 108 acts on the pin contact 101, and the pin contact 101 is pressed by the spring 108. As a result, the spring 108 and the pin contact 101 are electrically connected. After inserting the pin contact 101 into the socket contact 107, the female connector 1
The electrical connection between the conductor 110 and the conductor 109 is maintained by maintaining the connection between the female connector 112 and the male connector 111 by the lock mechanism 105 provided in the connector 12.

The above-mentioned detachable connector is an improved detachable push-pull detachable connector which is conventionally used on the ground, for use in satellites and the like.

As means for obtaining an electrical connection, 2
An anisotropic conductive film has been proposed in Japanese Patent Application Laid-Open No. Sho 61-142606 in order to electrically connect multiple electrodes of two substrates. Further, a hollow cylindrical anisotropic conductive rubber has been proposed in Japanese Utility Model Laid-Open Publication No. 4-59070 to electrically connect conductor patterns formed on each of the opposing substrates.

[0009]

However, in the conventional separated connector, the electrical connection between the connectors is made by pressing the pin contact by the elastic force of the spring inside the socket contact. When the number of contacts and socket contacts increases, there is a problem in that when the separation connector is separated, a large pulling force is required to pull out the pin contact inserted into the socket contact. The reason is that if a pin contact provided on one connector is pressed (pinched) into the other connector by mechanical pressure, frictional force is applied to the pin contact when pulling out the pin contact. Because it works.

Also, when the pin contact is inserted into the socket contact, the pin contact receives a frictional force from the spring inside the socket contact. Therefore, when the number of the pin contact and the socket contact increases, the pin contact becomes the socket contact. A large pressing force is required for insertion.

SUMMARY OF THE INVENTION In view of the above-mentioned problems of the prior art, it is an object of the present invention to disconnect one connector and separate it from the other connector with as small a pulling force as possible. To provide a separation connector which can be separated by a separation mechanism.

An anisotropic conductive elastic body is sandwiched between them and pressed. Thereby, a plurality of electrical connections between the pin contacts of the first and second connectors are reliably obtained. In addition, since a large force is not required when separating the connected connectors, operability when separating the connectors is improved. As a result, when the separation connector of the present invention is used for electrical connection between space vehicles, the separation mechanism of the separation connector when separating the space vehicles can be greatly simplified. Further, even if the number of pin contacts of the connector increases and the number of electrical connections between the pin contacts increases, the force required to separate or connect the connectors does not increase.
