Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a contact structure of a connector in which the contacts of a male connector and the contacts of a female connector overlap and make contact.

In conventional connectors of this type, in order to ensure that the contacts of the male connector and the contacts of the female connector are in contact with each other, one or more positioning functions are added to the insulator that constitutes the connector. Alternatively, there is a type in which a positioning function is added to each contact and an insulator covering the contact.

FIG. 1 is a partially cutaway perspective view of a small connector in which the contacts of a male connector and the contacts of a female connector are aligned using an insulator of the female connector. In the figure, 1 is a male connector, and 2 is a female connector. Showing the connector.

Here, the male connector 1 includes an insulator 3 and a plurality of resilient round rod-shaped contacts 4 aligned and fixed to the insulator 3 at predetermined intervals, and the female connector 2 forms a plurality of partition walls 5. The insulator 6 and each partition wall 5
It is provided with a flat plate-shaped contactor 7 provided in between.

Note that 4a is a terminal portion formed at the rear of each contact 4, and 7a is a terminal portion formed at the rear of each contact 7.

In the connector with this configuration, when the male connector 1 and the female connector 2 are fitted together with their contacts 4 and 7 facing each other, each contact 4 of the male connector 1 is guided to the partition wall 5 of the female connector 2. The contact 7 of the corresponding female connector 2 overlaps with the contact 7 of the corresponding female connector 2, thereby making it possible to bring both the contacts 4 and 7 into contact. 4 rubs against the partition wall 5, a part of the partition wall 5, which is an insulator, peels off and adheres to the contacts 4, 7, which causes a problem in contact between the contacts 4, 7.

In addition, the distance between the contacts 4 and the distance between the contacts 7 must be increased by the thickness of the partition wall 5, which has the disadvantage that it is difficult to achieve miniaturization.

The purpose of the present invention is to solve these drawbacks, and therefore, the cross-sectional shape of one of the contacts of the male connector and the female connector is made convex, and the cross-sectional shape of the other contact is made concave. By providing a positioning function, the structure eliminates the need for partition walls that cause contact failure and hinder miniaturization of the connector.

To explain the following with reference to the drawings, FIG. 2 is a partially cutaway perspective view showing an embodiment of the present invention, and 8
9 indicates a male connector, and 9 indicates a female connector.

Here, the male connector 8 includes an insulator 10 and a plurality of resilient round rod-shaped contacts 11 aligned and fixed to the insulator 10 at predetermined intervals, and the female connector 9 includes an insulator 12 and The body 12 is provided with flat elastic contacts 13 aligned and fixed at the same intervals as the contacts 11, and the contacts 13 of the female connector 9 and the tips of the contacts 11 of the male connector 8 are connected to each other. are curved in opposite directions to improve fitability. The section from the tip of the contact 13 of the female connector 9 to the insulator 12 is formed to have a concave curved surface as shown in FIG. Contactor 1 of male connector 8 having a shaped curved surface
It corresponds to 1.

Note that 11a is a terminal portion formed at the rear of each contact 11, and 13a is a terminal portion formed at the rear of each contact 13.

The connector having the above configuration has a male connector 8
When the female connector 9 and the female connector 9 are fitted together with their contacts 11 and 13 facing each other, each contact 11 of the male connector 9 will fit in a predetermined position along the concave curved surface of the corresponding contact 13 of the female connector 9. are inserted to the position of , and contact each other in an overlapping state. In other words, the cross-sectional shapes of the contacts 11 and 13 of the male connector 8 and the female connector 9 have an uneven relationship with each other, and since the contact 11 is round bar-shaped and has elasticity in the direction of the adjacent contacts 11, the male Even if there is a slight discrepancy between the spacing between the contacts 11 of the connector 8 and the spacing between the contacts 13 of the female connector 9, the contacts 11 and the corresponding contacts 13
As a result, the contacts 11 and 13 overlap with their centers coincident, and the two contact each other reliably.

In addition, in the above-mentioned embodiment, the contact of the male connector was made into a round rod shape, and the contact of the female connector was made into a plate shape with a concave curved surface, but the shapes of both contacts may be reversed, and the cross-sectional shape of both contacts may be changed. If they have an uneven relationship with each other, even if both contacts have the elasticity that generates the contact force between both contacts and the elasticity in the direction perpendicular to this, that is, the elasticity in the direction of the adjacent contact, Needless to say, it's a good thing.

As explained above, in this invention, the contact surfaces of the male connector contact and the female connector contact are made into concave and convex shapes to provide a positioning function. It is not necessary to form the partition wall with an insulator, so it is possible to prevent contact failure due to separation of the partition wall, and it is also possible to downsize the connector, making it suitable for the contact structure of all small connectors. It is particularly effective for connectors with a large number of contacts.
