Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a two-piece connector in which the contacts of the first and second connectors have the same shape.

Conventionally, there are various two-piece connectors consisting of a male connector and a female connector that can be fitted together, but in all of them, the shapes of the contact parts of the contacts are different for the male and female types, and the shapes are complex. Therefore, it takes a lot of time to manufacture the contacts, and the workability is poor.Moreover, since a mold suitable for each contact must be manufactured and used, the cost is high, which is not favorable from an economical point of view. Furthermore, since the contact has a complicated shape and is large, it has been difficult to increase the packaging density.

The present invention has been made to solve these problems, and allows the contacts of the first and second connectors that can be fitted to each other to have the same simple shape, thereby reducing manufacturing costs and reducing the overall size. The present invention aims to provide a two-piece connector that can increase the packaging density.

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

First, it is a sectional view of the first and second connectors CNI and CN2 shown in FIGS. 1 and 2 for the first embodiment. The first connector CNI has a substantially rectangular parallelepiped shape as a whole, and has a space SRI opened on the front side.
A housing having a substantially U-shaped cross section and a center wall W1 having a rectangular cross section at the bottom of one side, for example, an insulating weight S1, and a plurality of rod-shaped conductive elastic materials arranged in a line in the space SRI are crushed or processed. Contact C made by cutting
It consists of 1. In the insulator ISI, a plurality of linear contact insertion holes H1 are formed in one row from the center of the ventral surface of the space SRI, and a free end of the contact C1 is formed on the wall on the back side of each contact C1 of the space SRI. A space S1 is formed in which the sides can be displaced, and a center wall WR of an insulator IS2 of a second connector CN2, which will be described later, is formed in the space SRI.
2 and contact C2 can both be inserted.

Each of the contacts C1 is rod-shaped and has an arc-shaped contact portion C1l at its tip, and as it goes toward the free end side excluding this contact portion C1l, or toward the root portion (fixed portion) C12 on the opposite side, A gently sloped surface portion C13 is formed so as to gradually become thicker.This sloped surface portion C13
The appropriate angle for this angle is in the range of 3" to 15@, and here it is 4°.Contact C with such a configuration
1 are respectively inserted into the contact insertion holes 1 of the insulator IS1 toward the right side wall WR1 of the inclined surface portion C13.

The second connector CN2 includes a housing having a substantially T-shaped cross section, for example, an insulator IS2 and a contact C of the first connector CNI.
1 and a contact C2 having the same shape. The insulator IS2 has a shape in which a convex section and a rectangular section are integrally formed, and a straight contact insertion hole H2 is formed at the joint surface W2 between the convex section and the rectangular section. A plurality of them are formed in one row. The contact C2 is
This inclined surface portion C23 is inserted into the contact insertion hole H2 of the insulator IS2 so as to face opposite to the central projecting wall WR2. In addition, C21 is a contact part, C22 is a root part (fixed part), and S2R is a space formed so that the said center protrusion wall WR2 and the free end of contact C2 may be freely displaced.

The first and second connectors CNI configured in this way
, CN2, first contact CI,
The contact portions C1l and C21 of C2 come into contact with each other, the tips of the contacts CI and C2 curve in opposite directions, and the contact portions C1l and C21 cross over each other. Next, these contact portions C11°C21 slide along the sloped surface portions C2B and C13 of the mating contacts C2 and CI, and this sloped surface portion C
23, C13 connects contact C2, contact portion C of CI
1l and C21 curve more, and finally, as shown in FIG.
, C24.

Then, the contact portions C1l and C21 are pressed against the flat contact portion with a predetermined contact pressure by the elastic force caused by the curvature of the inclined surface portions C13 and C23, thereby establishing electrical contact.

In FIG. 3, the free ends of the contacts C1 and C2 are curved in the first and second connectors CN1. C
This is because spaces S1 and S2R are formed in the N2 insulators ISI and IS2, respectively, and the free end sides of the contacts C1 and C2 are in contact with each other.

The first and second connectors CN1 that can be fitted to each other in this way
．． Since the contacts CI and C2 of CN2 can be made into the same shape, it takes less time to manufacture the contacts, and the workability is good, and the same mold can be used to manufacture the contacts C1 and C2. It is also economically advantageous because the manufacturing cost is low and the cost is low.

Further, since the contact portions C1l and C21 are in contact with each other at two places, the reliability of electrical contact is high.

Furthermore, the free end sides of the contacts CI and C2 on the side having the contact portions C1l and C21 are rod-shaped and contact each other in a state where they are stacked parallel to each other, so the space occupied by these is small, and the whole can be made smaller. Packaging density can be increased.

Further, since the contact portions C11°C21 of the contacts C1 and C2 are arcuate, when the contact portions C11°C21 slides on the inclined surface portions C13°C23 of the contacts CI and C2, the contact portions C11°C21 Inclined surface portion C13,C
23 moves, and the contact parts C11 and C21
gradually curves while sliding on the other party's inclined surface parts C13, C2B, so the angle with respect to the other party's contact parts C1l, C21 changes sequentially. Moving.

In this way, the inclined surface portions C13 and C of the contacts C1 and C2
23 and the contact portions C1l, C21 are not fixed to one place, and local wear of the contact portions C1l, C21 can be prevented. In addition, if the contact portions C1l and C21 of the contacts CI and C2 ride on the flat contact portion, the contact portion C1l and C21
11°The parts that come into contact with C21 are the contact parts C1l and C21
is at a different position from the contact point where it contacts the inclined surface portions C13 and C23, so the flat contact portion C14゜C24 and the contact portion C
The abrasion of the contact points 1l and C21 is small, and it is possible to prevent the electrical contact characteristics from deteriorating due to abrasion.

The flat contact portion C14 of the contact C1 comes into contact with the side surface of the center wall W1 on the side of the root portion C12, and the flat contact portion C24 of the contact C2 comes into contact with the joint surface W2 between the convex section and the rectangular section. Since they are in contact with each other, the contacts C1 and C2 are connected to the insulator IS1. l521: When assembling, etc., the contact portions C1l, C21 and the contact flat portion reliably form independent two-point contact without deforming the root portions C1l, C22 of the contacts CI, C2. Also, temporarily contact CI.

Even if one of the contact portions of C2 is deformed, the remaining contact portion and the flat contact portion always make contact at one point, so the reliability of contact is high.

In addition, since the contacts C1 and C2 are formed by simply forming the contact portion c11°C21 and the inclined surface portions C13 and C23 by crushing or cutting a rod-shaped material, there is no need to use bending, which is difficult to achieve dimensional accuracy. Moreover, since the external dimensions of the contact portions C1l and C21 are equal to or smaller than the external dimensions of the root portions C12 and C22, the insulator I
S.I.

When assembling the contacts C1 and C2 on IS2, the assembly workability is good because it can be done from either the bottom side or the top side of the insulators ISI and IS2.

Furthermore, the contact portion C1l is attached to the contact flat portions C14 and C24,
After C21 rides on it, it slides a predetermined distance, thereby cleaning the contact portions of the contact portions C1l and C21.

FIG. 4 is a sectional view showing a second embodiment of the present invention, and the first embodiment has first and second connectors CNI and CN2.
The shapes are different from each other, but in FIG. 4, the first connector CNI and the second connector CN2 have the same shape and are arranged oppositely. That is, contact CI.

The terminals C15 and C25 of C2 are bent in directions deviated from each other by 180''. It goes without saying that the same effect as in the first embodiment can be obtained in this case as well.

According to the present invention as described above, the first and second
It is possible to provide a two-piece connector in which the contacts of the two connectors can be made into the same shape, and therefore the manufacturing cost is low, the overall size can be reduced, and the packaging density can be increased.
