Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a short-circuit contact capable of contacting two pins in an electronic device such as a personal computer.

[0002]

2. Description of the Related Art In electronic equipment such as personal computers, for example, a plurality of pins (terminals) are erected on a printed circuit board,
Some of these pins are not electrically connected to each other. By connecting the two pins, an electric circuit leading to these pins can be made conductive (short-circuited). For this,
A short-circuit contact that can connect two pins is needed.

Conventionally, there are a short-circuit contact 1 shown in FIG. 7 and a short-circuit contact 1 shown in FIG. The short-circuit contact 1 of FIG. 7 has a pair of contact portions 2 and another pair of contact portions 3.
(Only one is visible in FIG. 7), and one pin is elastically sandwiched between the pair of contact portions 2,
The other pin is elastically sandwiched between the other pair of contact portions 3, so that the two pins can be electrically connected by the short-circuit contact 1. On the other hand, the short-circuit contact 1 of FIG. 8 is composed of one contact portion 2 and another contact portion 3, and one pin is elastically pressed by one contact portion 2,
The other pin can be elastically pressed by the other contact part 3, so that the two pins can be brought into conduction by the short-circuit contact 1. In this case, a structure for pressing the short-circuit contact 1 from the back is necessary.

[0004]

These pins, which stand on the printed circuit board, are arranged at a very small pitch. Therefore, the short-circuit contacts must be of small construction and of sufficient elasticity to be able to maintain contact with the pins for an extended period of time. The short-circuit contact 1 shown in FIG. 7 has a limit to make it small, and although the short-circuit contact 1 shown in FIG. 7 can be made small, it cannot be said that the structure provides sufficient elasticity.

It is an object of the present invention to provide a short circuit contact that is small and capable of providing elastic contact.

[0006]

A short-circuit contact according to the present invention is made of a plate-shaped conductive material and has a central body portion and contact portions located on both sides of the body portion, and each contact portion is the body portion. Are connected to each other in a connecting region and are separated from each other in a region on the other end side, and the contact portion is bent substantially perpendicularly from the body part in the region on the one end side to have a U-shaped cross section as a whole. In addition to having a shape, the region on the other end side of each contact portion is bent outward in a substantially V shape, and the contact portion is arranged between two pins when used, and each contact portion is Characterized by being able to contact the pin.

[0007]

In the above structure, the contact portion is arranged between the two pins so that each contact portion can come into contact with each pin during use. This short-circuit contact can be used with very small pitch pins. Since each contact part is bent substantially vertically from the body part and further bent in a substantially doglegged shape, it can be sufficiently elastically deformed and can maintain contact with the pin for a long period of time.

Further provided is a short circuit socket having such a short circuit contact housed in an insulating housing. This short-circuit socket has the characteristics of the above-mentioned short-circuit contact and is effective for use as a product standardized by size.

It has a central body portion 12 and contact portions 14 and 16 located on both sides of the body portion 12. The contact portions 14 and 16 are connected to the body portion 12 at a region 18 on one end side and separated at a region 20 on the other end side.

Each of the contact portions 14 and 16 is bent substantially perpendicularly from the body portion 12 in the joining region 18 and has a generally U-shaped cross-sectional shape. Furthermore, each contact portion 14,
A region 20 on the other end side of 16 is bent outward in a substantially doglegged shape. The bending position of the center of the dogleg is the contact point 1
It is an intermediate portion of the region 20 on the other end side of the Nos. 4 and 16. Further, the end portion of the body portion 12 opposite to the joint portion with the contact portions 14 and 16 includes a flap 22 bent substantially perpendicular to the body portion 12.

In FIG. 1, two pins 32, 3 having a rectangular cross section are provided.
A printed circuit board 30 including 4 is shown. In practice, the printed circuit board 30 contains a larger number of pins. The size of the short-circuit contact 10 is such that the contact portion 1 is
4 and 16 are arranged between the two pins 32 and 34 so that the respective contact portions 14 and 16 can contact the respective pins 32 and 34. Since the contact portions 14 and 16 are bent substantially vertically from the body portion 12 and are bent in a substantially dogleg shape, the contact portions 14 and 16 are bent to the pin 3 respectively.
It is in direct contact with the surfaces of 2, 34 and is sufficiently elastically deformable. Therefore, the contact portions 14 and 16 can maintain contact with the pins 32 and 34 for a long period of time.

FIG. 2 is a diagram showing a short-circuit contact 10 according to a second embodiment of the present invention. This short circuit contact 10 is similar to the short circuit contact 10 of FIG. That is, the short-circuit contact 10 includes a central body portion 12 and contact portions 14 and 16 on both sides, and each of the contact portions 14 and 16 includes the body portion 1.
2 are connected to each other at a region 18 on one end side and are separated from each other at a region 20 on the other end side. The contact portions 14, 16 are bent substantially perpendicularly from the body portion 12 in the joining region 18 and have a generally U-shaped cross-sectional shape. Further, the region 20 on the other end side of each of the contact portions 14 and 16 is bent outward in a substantially dogleg shape. Further, the contact portion 1 of the body portion 12
The end opposite to the connection with 4, 16 comprises a flap 29 which is bent substantially perpendicular to the body 12. This flap 29 is bent on the side opposite to that of FIG. 1, ie on the same side as the contact parts 14, 16.

The short circuit contact 10 of FIG. 2 is housed in the insulating housing 40 of FIG. 3 and is used as the short circuit socket 50 of FIG. This short-circuit socket 50 is shown in FIG.
It is used as shown in.

0 has four side walls 40a, 40b, 40c, 40d and one bottom wall 40e, which form a recess 42 into which the short-circuit contact 10 can be inserted. The recess 42 opens on the top side of the insulating housing 40 (visible in FIG. 4), and a small hole 44 is provided in the bottom wall 40e (visible in FIG. 3). The columnar wall 40f extends from one side wall 40a toward the opposite side wall 40c so as to project into the recess 42, and a gap 42a is formed between the side wall 40c and the columnar wall 40f as a part of the recess 42. It

The body portion 12 of the short-circuit contact 10 is inserted into this gap 42a, and the contact portions 14 and 16 are recessed 4
It is inserted into each side of the two columnar wall portions 40f. One ends of the body portion 12 and the contact portions 14 and 16 abut the bottom wall 40e, the body portion 12 is supported by the columnar wall portion 40f, and the flap 22 abuts the upper surface of the columnar wall portion 40f. Flap 2
2 is joined to the upper surface of the columnar wall portion 40f by an appropriate means. In the embodiment, the flap 22 is fixed to the columnar wall 40f by thermal bonding. Therefore, a gap is formed between the contact portion 14 and the side wall 40d and between the contact portion 16 and the side wall 40b, and the pins 32 and 34 can be inserted into this gap. At this time, the contact portions 14 and 16 elastically deform while contacting the pins.
