Description

[Detailed explanation of the idea] <Industrial application field> The present invention relates to a connector.

<Prior art> Since a conventional connector operates by fitting a male connector and a female connector into each other, there are at least four connectors: a male main body, a male contact, a female main body, and a female contact. Four types of parts were required.

<Problems that the invention aims to solve> However, since the connector requires four pieces and four types of parts, the number of connector production processes increases and the initial investment in the production process becomes enormous. The point was hot.

This idea was devised in view of the above circumstances.
The purpose is to provide a connector that requires fewer types of parts and requires less initial investment.

<Means for solving the problem> The connector according to the present invention is a connector that can electrically and mechanically connect two connectors of the same shape facing each other, and is capable of electrically and mechanically connecting two connectors of the same shape facing each other. It has a positioning means for positioning, an insulating main body from which a plurality of contact holding parts are formed protrudingly, and a conductive contact pin held by the contact holding parts. The contact holding portion has a pair of walls sandwiching a central member, and when connectors of the same shape are connected, the contact holding portion of one connector fits between the contact holding portions of the other connector. The contact pins are arranged in two rows alternately at regular intervals, and the contact pins have a substantially J-shaped fitting part and a lead part extending outward from the main body. and the fitting part are held in the contact holding part by sandwiching the central member, and when another connector is connected,
The fitting portion is configured to fit with a fitting portion of a contact pin of another connected connector.

<Function> By attaching the connector according to the present invention to a printed circuit board and fitting connectors of the same shape together,
Two printed circuit boards can be electrically and structurally connected.

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

FIG. 1 is a partially cutaway perspective view of a connector according to the present invention.

The main body 10 includes a plurality of contact holding parts 11,
It has positioning means 12.

If the intersection of the diagonal lines of the main body 10 is the center of point symmetry, the plurality of contact holding parts 11 and the two positioning means 12 are each arranged at 180 degrees point symmetry. That is, the two positioning means 12 are formed at both left and right ends of the main body 10, and the plurality of contact holding parts 11 are divided into two rows and three each are formed alternately. Note that when connecting connectors of the same shape, this contact holding portion 11 is similar to the contact holding portion 11 of the other connector.
The contact holding parts 11 are formed with an interval slightly wider than the thickness dimension of the contact holding parts 11 so that the contact holding parts 11 fit between the contact holding parts 11 .

The contact holding portion 11 having an H-shaped cross section is sandwiched between a wall portion 111 having a tapered surface 111a and two wall portions 111, and is provided approximately at the center of the wall portion 111, and is located above the height of the wall portion 111. The center member 112 has a low, substantially rectangular bar shape.

The wall portion 111 has a substantially trapezoidal shape, and as shown in FIG. 1, if the length of the upper side of the wall portion 111 is a, the length of the lower side is b, and the length of the short side of the main body 10 is c, then c= a
+b, and the relationship a<b holds true.

The contact holding parts 11 are arranged in a staggered manner parallel to the short sides of the main body 10 with the tapered surfaces 111a facing inside the main body 10.

The positioning means 12 provided along the short side of the main body 10, that is, provided at both left and right ends of the main body 10, has a first positioning boss 121 and an opening 1.
22, a second positioning boss 123, and a notch 124.

The square columnar first positioning boss 121 is disposed on the shorter side of the main body 10 than the contact holding part 11, is formed taller than the contact holding part 11, and has a tip portion that is easily inserted into the opening 122. A taper is formed.

The square columnar second positioning boss 123 is formed to be shorter than the first positioning boss 121.

An opening 122 is provided between the first positioning boss 121 and the second positioning boss 123.

The notch 124 is provided on the opposite side of the second positioning boss 123 and adjacent to the first positioning boss 121.

In other words, the second positioning boss 123, the opening 12
2. The first positioning boss 121 and the notch 124 are arranged in this order.

A pedestal 16 for making the distance between the main body 10 and the printed circuit board 30 constant is provided below between the contact holding parts 11 on the back surface of the main body 10. Furthermore, a substantially cylindrical mounting boss 17 for positioning the main body 10 is not shown in FIG.
A predetermined number of protrusions are provided at predetermined positions on the back surface of 0.

The contact pin 20 is formed by bending an elongated metal plate or metal wire, and has a fitting part 21 and a lead part 22.

The fitting part 21 has a substantially J-shape, and the lead part 22
extends from one end of the fitting portion 21, and the contact pin 20 has a generally S-shape as a whole.

The contact pin 20 sandwiches the center member 112 of the contact holding portion 11 of the main body 10 between the lead portion 22 and the fitting portion 21 .

The shape of the lead portion 22 of the contact pin 20 is not limited to the deep type shown in FIG. 1, but may be the reflow type shown in FIG. Needless to say, a right-angle type may also be used.

Next, an example of the use of the connector according to the present invention will be explained with reference to FIG.

FIG. 2 is a partially cutaway perspective view of two printed circuit boards 30 electrically and structurally connected using the connector according to the present invention.

Note that a connector in which the lead portion 22 is of a reflow type and a connector of a deep type are given as examples.

The printed circuit board 30 has a lead portion 22 at the front.
The number of through holes 31 for lead parts corresponding to
and a mounting boss hole 32 corresponding to the mounting boss 17 provided on the back surface of the main body 10.

Both connectors are attached to both printed circuit boards 30 by soldering the lead portions 22 of each connector. Note that the lead portion 22 is connected to the printed circuit board 3.
It is connected to an electric circuit (not shown) configured on the 0.

Furthermore, both connectors are made to face each other and are fitted together. At this time, the first positioning boss 121 and the second positioning boss 123 are inserted into the opening 122 and the notch 124, respectively. Further, the contact holding portions 11 of each connector are fitted between the contact holding portions 11 of the other party.
That is, the wall portion 111 of the contact holding portion 11 contacts the wall portion 111 of the contact holding portion 11 of the mating connector, and the tapered surface 111a contacts the tapered surface 1 of the contact holding portion 11 of the mating connector.
11a.

At this time, since the fitting portions 21 of the contact pins 20 are fitted into each other, both printed circuit boards 30 are electrically and structurally connected via both connectors.

<Effects of the invention> According to the connector according to the invention, bodies of the same shape are fitted together, so there is no need to manufacture two types of bodies, a male type and a female type. Therefore, the number of parts to be produced is reduced from 4 pieces and 4 types to 4 pieces and 2 types, thereby reducing the number of connector manufacturing processes and reducing the initial investment amount for the manufacturing process.
