Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cord fixing device for fixing a power cord connected to electric equipment and a wiring cord used for internal wiring of electric equipment and the like.

[0002]

2. Description of the Related Art A cord used for electrically connecting an electric device or the like is usually fixed using a commercially available nylon clamp or the like.

FIG. 7 is a schematic plan view showing a wiring state when a cord is fixed on a substrate using a cord fixing device according to the prior art. In FIG. 7, the substrate 1
01, a plurality of electric devices such as a relay and a terminal block (the first device 102, the second device 103, and the third device 1).
04) are electrically connected using a plurality of cords. Here, the first device 102 and the second device 1
03 is connected using a first code 105, and the second device 103 and the third device 104 are connected using a second code 106. Each of the cords 105 and 106 is fixed to the board 101 using a cord fixture 110 including a nylon clamp 111 and a screw 112.

In FIG. 7, each of the cords 105 and 106 is fixed by using a plurality of cord fixtures 110. Specifically, a substrate 101 and a nylon clamp 111 are fixed.
In this state, the nylon clamp 111 and the substrate 101 are screwed together with the screws 112 while the cords 105 and 106 are held therebetween.

[0005]

However, according to the above prior art, a hole for screwing the screw 112 when fixing the cords 105 and 106 needs to be formed in the substrate 101 in advance. Therefore, there is a problem that the wiring direction when wiring the code is naturally limited, there is no flexibility in the wiring direction, and it is not easy to change the wiring direction.

According to the above prior art, the code 10
Since a nylon clamp 111 and a screw 112 are required as members for fixing the 5, 106, the cost is inevitably increased. Further, code 105,
Since the step of screwing the screw 112 is always required when fixing the 106, there is a problem that the operation for fixing the cords 105 and 106 is complicated.

Therefore, the present invention has been made to solve the above-mentioned problem, and it is easy to change the wiring direction when wiring and fixing a cord, and it is not necessary to use a member such as a nylon clamp. It is an object of the present invention to provide a cord fixing device capable of easily performing an operation for fixing a cord.

[0008]

That is, a cord fixing device according to the present invention for solving the above-mentioned problems comprises a plurality of projections 11, 21, 31 provided on a substrate. It is a cord fixing device having a function of fixing the cord by sandwiching the cord between the cords 21 and 31.

In the cord fixing device according to the present invention, a cord fixing device is constituted by using a plurality of projections 11, 21, and 31. By sandwiching the cord between the cord fixing devices, a straight portion of the cord and Curved portions are effectively fixed. Therefore, according to the present invention, it is possible to configure a cord fixing device without using a nylon clamp or the like required in the related art.
The cost for the nylon clamp and the like can be reduced. Further, according to the present invention, the conventional technique was used,
Work such as clamping the cord between the nylon clamp and the board and screwing the nylon clamp and the board together with a screw becomes unnecessary, and the cord is connected to the protrusions 11, 21 and 21.
Since the cord can be fixed by being sandwiched between the cords 31, the work process for fixing the cord can be greatly simplified.

The cord fixing device according to the present invention comprises three or more projections 11, 21, 31. The cord is sandwiched between the projections 11, 21, 31, and the wiring direction of the cord is changed. It is preferable to have a function of fixing the code arbitrarily.

According to this preferred example, since the cord fixing member is formed from three or more of the protrusions 11, 21, 31, it is possible to easily change the wiring direction as required.

Further, the cord fixing device according to the present invention is preferably configured such that the protruding portion 31 is detachably provided on the substrate. Due to this configuration, a plurality of openings are provided on the substrate. Preferably, a portion 41 is formed, and the projection 31 is configured to be attachable to the opening 41.

According to this preferred example, a plurality of the openings 41 are formed on the substrate, and the projections 31 are attached to appropriate portions of the openings 41 to constitute a cord fixing device. , Wire diameter and number of cords to be wired and fixed,
Alternatively, it is possible to freely change the arrangement of the projections 31 according to the wiring direction and the like, and it is possible to obtain a cord fixing tool having a large degree of freedom in the wiring direction and the like.

[0014] Further, the cord fixing device according to the present invention is preferably configured using the protruding portion formed so that the cross-sectional area of the crown is larger than the cross-sectional area of the root.
For example, the shape of the protrusion is preferably a truncated cone or a mushroom.

[0015] According to this preferred example, since the top of the head is larger than the root of the projection, the space between the tops of the projections is smaller than that between the roots. Therefore, according to this preferred example, when the cord is sandwiched and fixed between the projections, the cord is unlikely to come off from the root of the projection toward the crown, so that the cord is pinched. Power is big,
It is possible to obtain a cord fixing device in which the cord is hardly detached.

[0016]
