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 into each other, 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 shape of the contact is complex and 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. (11) The purpose is to provide a two-piece connector that can increase packaging density.

An embodiment of the present invention will be described below with reference to the drawings. FIGS. 1 and 2 respectively show first and second connectors CNI constituting a two-piece connector of the present invention;
It is a sectional view of CN2. The first connector CNI has an approximately rectangular parallelepiped shape as a whole and a housing having a convex cross section, for example, a pair of contacts C1 obtained by crushing or cutting an insulator ISI and a rod-shaped conductive elastic material.
It consists of The insulator ISI has a central wall W at the bottom.
A plurality of linear contact insertion holes H1 are formed along the opposing wall surface on the root side of the contact C1, and the center wall W1 has a convex cross section, and a space S1 in which the contact C1 can be displaced is formed on the free end side. The spaces SLI and SRI are formed by the left side wall WL1 and the center wall W1, and the right side wall WRI and the center wall W1.
are the left and right side walls WL2 of the insulator IS2 of the second connector CN2, which will be described later. WR2 can be inserted. Each of the contacts C1 is rod-shaped and has an arc-shaped contact portion C1l at the tip, and the contact portion C11 gradually curves toward the free end side other than the contact portion C11 or the root portion (fixed portion) C12 on the opposite side. Gently sloped surface portion C1 that becomes thicker
3 is formed.

The angle of this inclined portion C13 is suitably in the range of 3° to 15°, and here it is 4°.

The contact C1 having such a configuration has an inclined surface portion C1.
The insulator ISI toward the left and right side walls WLI and WRI of No. 3
is inserted into the contact insertion hole H1.

The second connector CN2 has a substantially rectangular parallelepiped shape as a whole, and has a hollow-shaped housing, for example, an insulator 152 and a first
The contact C2 has the same shape as the contact C1 of the connector CNI. The left and right side walls WL2゜WR2 of the insulator IS2 have a convex cross section, and a straight contact insertion hole H2 is formed on the bottom of the left and right side walls WL2゜W.
A plurality of each are formed along R2.

The contact C2 has this inclined surface portion C23 on the left and right side walls WL.
2. The insulator I faces toward the center opposite to WR2.
It is inserted into the contact insertion hole H2 of S2. In addition,
C21 is the contact part, C22 is the root part (fixed part), and S

and a space formed such that the free ends of the contacts C2 are freely displaced.
, 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 ell and C21 cross over each other. Next, these contact portions C11°C21 slide along the sloped surface portions C23 and C13 of the mating contacts C2 and C1, and the sloped surface portion C

13 and the root C12). Then, due to the elastic force due to the curvature of the inclined surface portion 013°
11°C21 is pressed against the contact flat part with a predetermined contact pressure,
Electrical contact is made.

Note that the contact flat portion is the contact portion C11°C21 in FIG.
refers to the flat surface that is in contact with the

In FIG. 3, the free ends of the contacts C1 and C2 are curved at the first and second connectors CN1. C
Spaces S1, S2L, and S2R are formed in N2 insulators JSI and IS2, respectively, and contacts CI and C
This is because the free ends of the two are in contact with each other.

In this way, the first . Second connector CNI
, CN2 contacts CI and C2 can be made into the same shape, so it takes less time to manufacture the contacts, and the workability is good, and the same mold can be used to manufacture the contacts CI and C2. Therefore, the manufacturing cost is low, and it is economically advantageous.

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 C1 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 this is small and the whole can be made smaller. Furthermore, the packaging density can be increased.

Further, since the contact portions C11°C21 of the contacts C1 and C2 are arcuate, when the contact portions C1l and C21 slide on the inclined surface portions 013°C23 of the contacts C1 and C2, the contact portions C1 and C21 are the same as the contact portions C1].

The contact points with the inclined surface parts C13 and C23 on C21 move, and the contact parts C1l and C21 are moved to the opposite inclined surface part C13.
, C23 gradually curves, so the angle with respect to the contact portions C11, C21 of the other party changes sequentially, and this also moves the contact points with the inclined surface portions C13, C23.

In this way, the inclined surface portions C13 and C of contacts CI and C2
23 and contact portion C], 1. The contact portion with C21 is not fixed to one location, and local wear of the contact portions C1l and C21 can be prevented. In addition, when the contact portions C1l and C21 of the contacts C1 and C2 ride on the contact flat portion, the contact portions C11° and C21 contact the contact portions C1l and C21.
is at a different position from the contact points that contact the inclined surface parts C1B and C23, so the wear of the contact points between the flat contact part and the contact parts C11°C21 is small, and the deterioration of the electrical contact characteristics due to wear is prevented. can.

The contact flat part of the contact C1 is the root part CI2, respectively.
The contact flat portions of the contact C2 abut against the opposite side surfaces of the side center wall W1, and the contact flat portions of the contact C2 contact the left side wall WL2 and the right side wall WL2, respectively.
Since it is in contact with one side wall on the root C22 side of R2,
Contacts C1 and C2 are connected to insulator IS1. When assembling to rs2, contact CI, root part C1l of C2,
The contact portions C1l and C21 and the contact flat portion reliably form independent two-point contact without deforming C22. Further, even if one of the contact portions of the contacts CI and C2 is deformed, the remaining contact portion and the flat contact portion are always in contact with each other at one point, so that the contact reliability is high.

In addition, for contacts CI and C2, the contact portion C11°C21 and the inclined surface portions C13 and C23 are simply formed by crushing or cutting a rod-shaped material, so that dimensional accuracy can be achieved (without using bending). 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 C02 on IS2, it can be done from either the bottom side or the top side of the insulators ISI and IS2, so the assembly workability is good.

Furthermore, after the contact parts C1l and C21 ride on the contact flat part, they slide by a predetermined distance, and as a result, the contact parts C1
The contact points of 1 and C21 are cleaned.

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.
