[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a socket connector used for a narrow pitch connector.

[0002]

2. Description of the Related Art In recent years, as electronic devices and the like have been reduced in size, connectors have been required to be reduced in size and pitch.

Conventionally, as a contact used for a narrow pitch connector, a socket contact 100 as shown in FIG. 7 has been known. This socket contact 10
Reference numeral 0 indicates that a plurality of socket contact bodies 101 having a single-layer structure as shown in FIG. 6 are arranged in parallel as shown in FIG.

[0004] Since it is not possible to form an insulating partition by a molding technique, in order to insulate between adjacent socket contact members 101, as shown in FIG. This is performed only by arranging the insulating material 102 on the surface facing the contact body 101). Then, as shown in FIG. 8, the pin contact 103 was fitted in a state of being pinched by the pinching portion of the socket contact body 101.

[0005]

However, when there is a slight dimensional deviation in the arrangement of the pin contacts 103, as shown in FIG. 8, the pin contacts 103 and the socket contact body 101 are properly fitted. Instead, the pin contact 103 often comes into contact with the adjacent pin contact 103 to cause a short circuit.

An object of the present invention is to prevent a pin contact from being guided to a regular position by a socket contact body even in a narrow-pitch connector having no insulating partition wall, so that adjacent pin contacts do not come into contact with each other. To provide socket contacts.

[0007]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention comprises a plurality of socket contacts arranged in parallel.
A base portion made of a soft material, and outer layers formed of a hard material harder than the base portion on both side surfaces in the arrangement direction of the base portion, and the base portion being a pin contact holding surface; A guide groove for accommodating a part of the pin contact is formed on a surface perpendicular to the arrangement direction.

FIG. 1 shows a material for manufacturing the socket contact of the present invention. The portion of the socket contact body 1 serving as the base portion 2 is made of a Cu-based alloy material. 3 is a rectangle integrally attached. The material is not limited to a rectangular shape because a press punching process is performed later. Next, a blank is formed by pressing the rectangular material as shown in FIG. A portion corresponding to the fitting portion of the blank thus obtained is etched as shown in FIG. 3 to obtain a guide groove portion 4 having a concave section in the plate thickness direction. The base portion 2 is a Cu-based alloy, and both outer layer portions 3
Is a stainless steel alloy, and therefore has a different workability for etching. The present invention is obtained by utilizing such a difference in workability between the two materials.

In the above embodiment, the base 2 and the outer layer 3
Are made of different materials, but are not limited thereto. That is, as shown in FIG.
The outer layer 3 is made of a Cu-based alloy, the base 2 is made of a soft material, the outer layer 3 is made of a hard material, and a blank is obtained by press punching as in FIG. A small portion of the surface of the soft base portion is removed (similar to FIG. 3) from the blank thus obtained by abrasive processing such as buffing or sandblasting to form a concave guide groove 4.

The plurality of socket contacts 1 thus obtained are arranged in parallel as shown in FIG. 4, and insulating materials 5 are arranged on both side surfaces of the socket contact 1. Usually, such an insulating material 5 is disposed on the surface at the material stage, and is usually formed by punching simultaneously with the base metal by the press punching process. Note that such an insulating partition wall 5 is not necessarily provided in a narrow pitch connector.

FIG. 5 shows a state where the socket contact body 1 sandwiches the pin contact 6. The pin contact 6 is held and accommodated in a concave guide groove 4 formed on the holding surface of the socket contact body 1.

[0013]

According to the present invention, even in a narrow pitch connector in which an insulating partition cannot be provided between each socket contact body, the pin connector is formed by the guide groove formed in the pin holding surface of the socket contact body. Since it is guided and firmly held and held in the fitted state, it is possible to prevent the pin contact from coming into contact with an adjacent pin contact even when the pin contact is bent or not aligned.
