Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an external electrical connector that electrically connects the terminals of a male and female connector to each other through a highly conductive contact powder.

Connectors commonly used for electrical coupling are:
The terminal of the male connector consists of a male connector molded with a male terminal with its end protruding, and a female connector molded with a female terminal equipped with a pair of spring contact members facing each other with a predetermined gap in between. Electrical connection is achieved by inserting the spring contact member between the female terminals of the female connector.

Such conventional connectors require a large insertion/extraction force to connect and open both connectors, and there are problems such as strain being applied to members such as printed boards that fix these connectors during operation. This is a major drawback, especially for connectors with a large number of terminals. SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to provide an electrical connector that can easily and reliably connect and open female and male connectors.

Embodiments of the invention will now be described with reference to the drawings. In FIG. 1, 1 is a male connector and 2 is a female connector.

The male connector 1 is constructed by molding a large number of non-magnetic terminals 3 into a main body la with both ends protruding.

At the base of the protrusion of the terminal 3 on the side facing the female connector 2, a cylindrical compression member 4 integral with the main body la is provided, as shown in detail in FIG. 2a. Female connector 2
As shown in FIG. 2b, the main body 2a is provided with holes 5 of a size in which the compression members 4 are fitted, at positions corresponding to the positions 3 of the female connector 1. A pre-magnetized attraction member 6 made of a hard magnetic material is fixed.

The adsorption member 6 is connected to a magnetic or non-magnetic terminal 7 molded on the main body 2a with one end protruding downward.
An appropriate amount of highly conductive contact powder (magnetic powder) 8 made of ferromagnetic material is inserted onto this connection part in the hole 5. The surface of this highly conductive contact powder 8 is coated with a material having a high aerocontact performance such as Au, Ag, or Sn, and when it is inserted into the hole 5, the adsorption part is closed as shown in FIG. The magnets are attracted to and held by the attraction member 6 in a state where they are aligned along the lines of magnetic force 6.
In addition, in the above description, an example was described in which the suction member 6 and the terminal 7 are provided separately, but the terminal may also serve as the suction member. In that case, the terminal should be made of hard magnetic material and bonded in advance. The structure of the electrical connector according to the present invention is as described above, and its operation will be explained next.

Now, as shown in FIG. 1, when the male connector head is opposed to the female connector 2 and pushed in while aligning the compression part 4 with the hole 5, the terminal 3 becomes bulky as shown in FIG. It enters into the highly conductive contact powder 8 which is arranged in a vine shape and held in the suction part village 6. Therefore, the insertion force required for pushing in is extremely small. In this state, for example, each connector 1,
Both connectors can be used by vertically connecting the two connectors by inserting bolts into holes 9 and 10' provided corresponding to the two connectors, and tightening nuts. In this case, the bulky and highly conductive contact powder 8 is sufficiently compressed by the compression member 4, and the terminal 3
, 7, stable contact with many contact points can be obtained through the highly conductive contact powder 8. To open both connectors, loosen the nuts, pull out the bolts, and then pull out the male connector to open it, but the pulling force at this time is almost zero.
When the terminal 3 is separated from the conductive contact powder 8, the conductive fin contact powder 8 immediately returns to the bulky arrangement shown in FIG. As described above, according to the present invention, the highly conductive contact powder is arranged and held by the attracting member in a raised state along the lines of magnetic force, so that it does not spill out from the connector. When both connectors are connected, not only can stable contact with many contact points be obtained between the male and female terminals through the highly conductive contact powder that is compressed into the compression part, but also the connection of both connectors.
The insertion/extraction force when opened is extremely small, which provides various excellent effects.
