Abstract

PURPOSE:To make it possible to reduce the margin for a metal mold as well as to enable a device of a multiple pole type and of a small size to be employed by letting connectors in a same form with contactor contacting points in odd numbers of rows be engaged with each other. CONSTITUTION:A connector assembly is composed of a connector main body 2a made of an insulating material, and of a housing 2 consisting of contacts 1a and 1b and a contact 1c which is arranged on the back of the contact 1b while these contacts are disposed oppositely to the aforesaid connector main body. The respective contacts are of spring performance so as to be pressed in the main body 2a while being lined up in three rows. When two housings 2 are engaged with each other symmetrically, connection is made in such a way that the contact 1a touches the contact 1c, the contact 1b touches the contact 1b and the contact 1c touches the contact 1a so that electrical connection is made between two printed wiring boards 3.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to electrical connectors, and particularly to unisex connectors that can be mated with each other in the same shape regardless of whether they are male or female connectors.

[Conventional technology]

Conventionally, in this type of electrical connector, the male connector and the female connector have housings made of insulators of different shapes, and two rows of contacts are press-fitted into the housing. That is, as shown in FIG. 4, when the male and A connectors are mated, the female housing 4 enters the male housing 5 to establish an electrical connection with the contacts 6 built into both housings.

[Problem to be solved by the invention]

The above-mentioned conventional electrical connector has the disadvantage that since the shape of the connector main body is different between the male connector and the female connector, two types of molding molds must be prepared, and a large amount of equipment cost is required.

Furthermore, in the case of conventional connectors, the contacts can only be arranged in two rows, so there is a drawback that multi-pole configuration cannot be achieved with three or more rows.

[Means to solve the problem]

The unisex connector of the present invention includes a connector main body made of an insulator, first and second contacts disposed opposite to each other on the connector main body, and a position of the connector main body facing away from the second contact. and a third contact disposed in the housing, and the two housings having the same shape are fitted symmetrically to each other to obtain electrical contact by each of the contacts. shall be.

〔Example〕

Next, the present invention will be explained with reference to the drawings.

1 and 2 are a perspective view and a sectional view of a main part of an embodiment of the present invention, and FIG. 3 is a sectional view showing a fitted state of two connectors according to this embodiment.

This embodiment includes a connector body 2a made of an insulator, and two contacts la facing each other on this connector body 2a.
, lb, and a third contact IC disposed at a position opposite to the contact 1b of the connector main body 2a, and the two housings 2 having the same shape
They are configured to fit together symmetrically to establish electrical contact. That is, the contacts la, lb, and lc are molded with spring properties and are press-fitted into the connector body 2a, and the contacts 3
arranged in columns. Note that the terminal leg of the contact is connected by through-hole solder to the printed circuit board hole.

Using this embodiment with such a configuration, two
By fitting two housings 2 symmetrically, three
Contacts with two spring properties are 1 a-+1 c,
1 b-+1 b and 1 c-+1 a, so that electrical contact between the two printed circuit boards 3 can be obtained. Further, in FIG. 1, portions C and D indicate fitting guides when two housings 2 are fitted symmetrically. On the D side, A dimension is 1/2 of 8 dimension.
By doing the following, connectors of the same shape can be fitted together.

In this embodiment, a case where the contacts are arranged in three rows is illustrated, but in addition to the three row configuration, any odd number of rows can be fitted by the same combination of connectors. In addition to connecting two boards in parallel as shown in this embodiment, by changing the shape of the terminal legs, it can also be used to connect two boards at right angles or to connect a cable to a board.

〔Effect of the invention〕

As explained above, the present invention allows connectors of the same shape and having an odd number of rows of contacts to be fitted together, so there is no need to make the male and female housings in two separate molds. effective. Therefore, since the number of molds can be reduced, the connector can be manufactured at low cost.

Furthermore, since this connector allows contacts to be arranged in three rows or more in an odd number, it has great effects, such as being able to accommodate multipolarization and miniaturization.
