Abstract

PURPOSE:To enable a cable and a contact to be separated from each other for reuse without any damage by jointing a contact pin of shape memory alloy to the cable under pressure and caulking and, then, restoring the initial shape of the contact pin under a certain condition. CONSTITUTION:A contact pin 103 of shape memory alloy is composed of a pin section 101 and a pressure connecting section 102 to be jointed to a cable under pressure and caulking, and the section 102 is caulked for connecting the cable, thereby providing wiring for transmitting an electrical signal. As a result, the cable and the contact pin 103 can be separated from each other and reused without any damage, when the wiring is placed in a condition for restoring the shape of the caulked section of the contact pin 103.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for recycling a product, and more particularly to a contact pin and a socket, and a cable, which can be easily separated and restored to their original shape under certain conditions. Regarding what to reuse.

[0002]

2. Description of the Related Art In the prior art, only means for enabling electrical connection is described, as in JP-A-1-42019, etc., and no consideration is given to sorting or reuse.

[0003]

The above-mentioned prior art considers only the advantages in manufacturing the product and cannot recycle the device after its life. For this reason, the increasing industrial waste of computers has been a problem.

An object of the present invention is to reduce industrial waste and effectively use resources by separating or reusing the contact pins / cables that have reached the device life or device failure.

[0005]

In order to achieve the above object, at least a shape memory alloy is used as the material of the contact pin, and a cloth for transmitting an electric signal in the device by crimping the cable and the contact pin. Become a line.

By placing the wiring under the condition that the contact pin returns to the shape before crimping during the life of the device, the contact pin is restored to its original shape, and the contact pin and the cable are separated and reusable. is there.

[0007]

[Operation] The used wiring can be reused by placing the used wiring under the condition that the shape of the contact pin is restored, and by returning the contact pin to the shape before crimping, the wiring and the contact pin are separated. You can

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described in detail below.

FIG. 1 shows the shape of the contact pin according to the present invention before use. FIG. 2 shows the shape of the wiring in which the contact pin and the cable are joined by pressure bonding. FIG. 3 shows the contact pins and cable treated for reuse.

In FIG. 1, 103 is a contact pin using a shape memory alloy, and a pin portion 101 for engaging with a socket of another part and a crimp portion 10 for crimping and joining with a cable.
It consists of two. In order to transmit an electric signal by using the above parts in the device, as shown in FIG. 2, the conductor wire portion 104 with the skin cover removed is placed in the crimping portion 102 and the electric signal is transmitted by crimping and crimping. It becomes a wiring. Here, in order to reuse the wiring due to device life etc., the shape of the crimping part of the contact pin returns to the original shape as shown in Fig. 3. By exposing the wiring under certain conditions, the shape of the crimping part returns and the cable is restored. Also, the contact pins can be easily separated without damage and can be sorted or reused. A contact socket and other parts that transmit electric signals by crimping and crimping can also be implemented in the same way.

[0011]

Industrial Applicability According to the present invention, it is possible to reduce industrial waste and promote effective utilization of resources by separating or reusing the contact pins and cables any number of times.
