Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable holding structure for holding an end portion of a cable electrically connected to an electric device in a retaining state with respect to a case of the electric device, and more specifically, an outer surface of the cable. The present invention relates to a technique in which a member is fixed to and a member comes into contact with a case of an electric device to prevent the cable from coming out.

[0002]

2. Description of the Related Art There is a technique disclosed in Japanese Patent Laid-Open No. 2000-353884 as a technique related to the cable holding structure configured as described above. In this conventional technique, the binding band is tightened and fixed to the cable, and the binding band is positioned between the movement restricting wall formed inside the case and the outer wall of the case, so that the pulling out and entering of the cable can be restricted. I am configuring.

[0003]

Here, in consideration of the attachment state of the cable to the case, it is important to restrict the cable from coming in and out like the conventional technique, but the rotation of the cable with respect to the case is prevented. Stopping is also important. In other words, in an electric device such as a controller for games where a twisting force is often applied to the cable during operation, the cable is rotated by the twisting force applied to the cable, and the board of the electric device and the cable inside the electric device are rotated. There was a case where a strong force acted between the lead wire and the lead wire and the connection portion was damaged.

Therefore, it is conceivable to provide a special member for preventing the rotation of the cable, but if the member for preventing the rotation is separately provided, it not only takes a lot of time at the time of assembly, but also the number of parts increases and the cost is increased. It cannot be said that it is effective in terms of

It is an object of the present invention to construct a cable holding structure capable of preventing the cable from slipping out of an electric device and also preventing the cable from rotating, with a small number of parts and facilitating assembly.

[0006]

The features, functions and effects of the cable holding structure according to claim 1 of the present invention are as follows. [Characteristics] In a cable holding structure for holding an end portion of a cable electrically connected to an electric device in a retaining state with respect to a case of the electric device, with a fixing piece that is bound and fixed to the cable, The case includes a retaining portion that comes into contact with the fixing piece to prevent the cable from coming out, and a detent portion that has a concave shape to prevent the cable from rotating when the protruding portion formed on the fixing piece is fitted. The point is that it is formed.

[Operation / Effect] According to the above characteristics, the cable can be prevented from coming off by bringing the fixing piece into contact with the retaining portion in a state where the fixing piece is tied and fixed to the cable. By fitting the formed protrusion into the concave rotation preventing portion, it is possible to prevent the cable from rotating in any direction. That is, according to the present invention, the cable can be prevented from coming off and the rotation can be prevented only by providing the fixing piece in a state of being bound to the cable and providing the retaining portion and the rotation preventing portion which can be easily formed at the time of molding the case. Becomes As a result, a cable holding structure that can easily be assembled is easily configured with a small number of parts that prevent the cable from coming out of the electric device and prevent the cable from rotating.

The features, functions and effects of the cable holding structure according to claim 2 of the present invention are as follows. [Characteristics] In the cable holding structure according to claim 1, an entrance preventing portion that comes into contact with the fixing piece and prevents entrance of a cable is formed in the case, and a member forming the entrance preventing portion, or The rotation preventing portion is formed integrally with the member forming the retaining portion.

[Operation / Effect] According to the above characteristics, when a force is applied in the cable entry direction, the fixing piece abuts the entry preventing portion to prevent movement of the cable in the entry direction. Since the member having the retaining portion or the member having the retaining portion for preventing the retaining by contact with the fixing piece is integrally formed with the retaining portion, The structure is simplified as compared with the case where the stopper is formed independently. as a result,
The structure that not only prevents the cable from being pulled out but also prevents the cable from entering and rotating has been simplified.

The features, actions and effects of the cable holding structure according to claim 3 of the present invention are as follows. [Characteristics] In the cable holding structure according to claim 1 or 2, the fixing piece includes a tie portion for binding to the cable,
The binding device is configured to have a lock portion that engages with the engagement surface formed on the tie portion to hold the binding state and that functions as the protruding portion. The point is that the tie part that is protruding from the lock part is cut off and removed while tied to.

[Operation / Effect] According to the above characteristics, since the fixing piece is composed of the tie portion and the lock portion, when the fixing piece is tied and fixed to the cable, the tie portion is tied to the cable. By attaching and locking with the lock part, it is possible to strongly provide a fixing piece for the cable in a state where tension is applied to the tie part, and by cutting and removing the part that is excessive from the tie part, It is possible to use only the portion that functions as the fixing piece. As a result, a cable holding structure that can be downsized without increasing the number of parts, such as the one using screws, was obtained.

The features, actions and effects of the cable holding structure according to claim 4 of the present invention are as follows. [Features] The cable holding structure according to claim 3, wherein the case has a shape that forms a space between the case body and the case body that is detachable from the case body and is attached to the case body. A holding case is formed, and a hole portion through which the cable is inserted is formed in the case main body and the holding case so that the opening edge of the hole portion of the case main body functions as the entrance preventing portion. The opening edge is cylindrically provided on the outer surface side, and a part of the projecting portion is cut out to form the detent portion, and the binding tool is provided at an intermediate position between the case body and the holding case. By tying and fixing, and by fixing the holding case to the case body in a state where the lock part of this tying tool is fitted in the rotation preventing part,
The point is that the hole formed in the holding case functions as the retaining portion.

[Operation / Effect] According to the above characteristics, the cable is inserted through the hole of the case body and the hole of the holding case,
Bind a binding tool to the cable at the intermediate position between the case body and the holding case, and fix the holding case to the main body case with the lock part of this fastening tool fitted in the rotation stop part of the protruding part of the case body. As a result, the fastener is sandwiched between the projecting portion and the hole of the holding case. As a result, by constructing the case, the case body that is separable, and the holding case, not only can the molding of the detent portion be facilitated, but also the removal and entry of the cable can be prevented,
The rotation of the cable can also be prevented.
