Abstract

PROBLEM TO BE SOLVED: To provide a mouse for a computer provided with a cord with excellent linearity which is not twisted non entangled and for which disconnection is not caused even when a cord diameter is small. SOLUTION: A mouse cord for the computer is formed by combining nine lead wires 2 around one super elastic alloy wire 1 and covering them with resin 3.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mouse used for pointing a screen of a personal computer (hereinafter referred to as a personal computer), and more particularly to the structure of a code used for the mouse.

[0002]

2. Description of the Related Art Conventionally, a mouse cord for a personal computer in which a lead wire is coated with resin has a drawback in that the linearity between the personal computer and the mouse is not good and twisting or entanglement occurs, which makes it difficult to operate the mouse. In addition, recently, with the downsizing of laptop computers and mouse bodies, the wire diameter of the mouse cord has become thin, and there is a drawback that the cord is inadvertently cut.

[0003]

SUMMARY OF THE INVENTION An object of the present invention, therefore, is to provide a computer mouse having a cord having the advantage of maintaining linearity and a method for manufacturing the same. Another technical problem is to provide a computer mouse capable of eliminating breakage of a cord having a small wire diameter, and a manufacturing method thereof.

[0004]

The present invention is characterized in that one to a plurality of superelastic alloy wires are combined with a mouse cord composed of a resin and a plurality of lead wires.

That is, the present invention is a mouse used in a computer, characterized in that the superelastic alloy wire and the lead wire are covered with a resin.

Further, the present invention is the above-mentioned computer mouse, wherein the superelastic alloy wire has at least superelastic characteristics in a temperature range of -40 to 80 ° C. The temperature range of −40 to 80 ° C. is set in consideration of the usage environment.

Further, the present invention is the above-mentioned computer mouse, wherein the superelastic alloy wire has shape memory characteristics.

In the present invention, the superelastic alloy wire has 50 to 51 at% Ni and the balance is substantially Ti, or 49.5 to 51 at% Ni, 0.1 to 2 at% X (provided that X is X. Is at least one of Cr, V and Co) and the balance is Ti.

BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of a mouse code for a personal computer according to the present invention will be described below.

FIG. 1 is a perspective view showing a mouse cord for a personal computer having a superelastic alloy wire according to an embodiment of the present invention. The mouse code for a personal computer of the present invention is obtained as follows.

Ti-5 obtained by high frequency vacuum melting
A 0.5 at% Ni alloy was formed into a wire rod having a diameter of 8 mm by a hot hammer and a hot roll. This wire rod is repeatedly subjected to cold wire drawing and heat treatment to obtain a wire rod having a diameter of 2.2 mm, and then cold working to a diameter of 0.1, 0.2, 0.3, 0.4, 0.5 mm (final Area reduction rate 40%)
Heat-treated for 5 minutes at a temperature of ℃, super elastic alloy wire 1
Got Here, one superelastic alloy wire 1 having the above wire diameter and nine lead wires 2 were combined and covered with resin 3 to obtain a mouse cord for a personal computer having a diameter of 2.0 mm and a length of 600 mm.

A rotation twist of 10 rotations was added to this, and R1
The reel of 0 was wound around 10 times and fixed. After holding at room temperature of 20 ° C. for 100 hours, it was released from the reel and its linearity was tested. The results are shown in Table 1. In Table 1, X marks indicate twists and bends, Δ marks indicate slight twists and bends, and ○ marks indicate
It shows that there is no twist or bend and that the linearity is good.

[0013]

[Table 1]

In Table 1, the linearity decreases as the superelastic alloy wire is not inserted or the wire diameter of the superelastic alloy wire is smaller, but twisting and entanglement do not occur in the wire having a large wire diameter. The linearity was good. Like the present invention, by combining the super elastic alloy wire and the lead wire,
By covering them with resin, it is possible to obtain a mouse code for a personal computer that suits the usage environment.

In the above embodiment, Ti-
An example using a Ni alloy is shown, but Ti-Ni-X (X
The same result can be obtained by using at least one of Cr, V, and Co.

[0016]

As described above, according to the present invention,
It was possible to provide a computer mouse having a cord that has good linearity, does not cause twisting or entanglement, and does not cause wire breakage even when the wire diameter is small.
