Description

[Detailed Description of the Invention] The present invention relates to a cable attachment mechanism for connecting electrical equipment 9 to communication equipment, etc.

Generally, a cable that is externally connected to an electric device 2 and a communication device is fixed to the device using a strong holding means, and then the core wire of the cable is connected to an electric circuit inside the device housing.

In this case, the external cable attachment mechanism must first have a simple structure, be easy to attach, have strong attachment, and be easy to remove the external cable.

Furthermore, when connecting to other electromechanical equipment, for example, as shown in Figure 1a, a connecting cable 1 including a core wire 1-1 extending from the equipment is generally provided with a holding fitting 2 for fixing the cable. There are many things.

As shown in FIG. 1, this holding fitting 2 includes a stopper portion 2-19, a positioning portion 2-2. It is integrally formed including the bending fixing part 2-3.

When attaching the cable 1 with the holding fitting 2 to an electrical device, etc., generally, as shown in FIG. It is attached to a mounting plate 3 such as a bottom plate of a device having a receiving portion 3-2 cut and raised by the above-described method.

That is, as shown in FIG. 2, the positioning part 2-2 of the holding fitting 2 is inserted into the holding fitting receiving part 3-2 of the mounting plate 3, and its movement in the left and right direction is restricted, and the stopper part 2
-1 is brought into contact with the inside of the bent portion 3-1 to restrict its movement in the front-back direction, and is further pressed against the lower end 6-1 of the cover 6, which is schematically shown in the figure, and is covered by the mounting plate 3, and moves in the vertical direction. is regulated and the cable 1 is fixed to the device.

Therefore, in conventional devices of this type, if the mounting plate 3 needs to be thick due to the weight to be placed or accommodated, bending or drawing may be difficult, and the mounting plate 3 is simply a flat plate. However, in such cases, the holding fitting 2 may be replaced with a completely different one suitable for the holding fitting 2, or another holding fitting may be provided separately from the conventional holding fitting 2, and screws, rivets, etc. Because the cable was fixed using an auxiliary fixing means on the ground, problems such as an increase in the number of parts and the provision of other fixing means occurred.

On the other hand, if we focus on the cable side, it goes without saying that it is better to use the conventional holding fitting 2 as it is without any modification in terms of compatibility, versatility, economy, etc.

The present invention was developed in order to eliminate the above-mentioned defects of the conventional mounting structure by reusing the conventionally used cable with a retainer in its original form without modifying or replacing it. It is something.

An embodiment of the present invention will be described in detail below based on the drawings.

FIG. 3 is an assembled structural diagram showing the mounting structure of the present invention, and the same parts as in FIGS. 1 and 2 are designated by the same reference numerals.

FIG. 1A is an assembled structure diagram showing a state in which the mounting plate 4 and the mounting bracket 5 are attached, and FIG.

First, in FIG. 3a, the mounting plate 4 is made of a flat plate, and a notch 4-1 and a guide hole 4-2 are formed at a predetermined position corresponding to the notch 4-1 at the end thereof.

A mounting bracket 5 shown in FIG. 4, which will be described later, is attached to the notch 4-1 and the guide hole 4-2.

That is, the mounting bracket 5 shown in FIG. 4 has a U-shaped cross section, and has a cable insertion groove 5-1 at one bent end and a cable insertion groove 5-1 on both sides to prevent it from falling off. A cut-and-raised portion 5-2 is formed including a shoulder portion 5-2-1 and a stopper surface 5-2-2 against which the holding fitting 2 of the cable 1 abuts.

On the other hand, the other bent end has a positioning portion 2- of the holding fitting 2 at a position opposite to the cable insertion groove 5-1 described above.
A receiving portion 5-3 for accommodating 2 is formed.

Therefore, as shown in FIG. 3a, this mounting bracket 5 has one end formed with a cut-out portion 5-2 at the cut-out portion 4-2 of the mounting plate 4.
1, the shoulder portion 5-2-1 abuts the mounting plate 4, and the other end where the receiving portion 5-3 is formed is inserted into the guide hole 4-
It is accommodated in 2.

Next, the case of attaching cable 1 will be described.

When installing the cable 1, first insert the positioning part 2-2 of the holding bracket 2 into the receiving part 5-3 of the mounting bracket 5 in the state shown in FIG. 3a, then insert the cable 1 into the mounting bracket 5.
It is only necessary to insert the cable into the cable insertion groove 5-1.

In this state, the mounting bracket 5 does not fall.

That is, the receiving part 5-3 is located at the positioning part 2- of the holding fitting 2.
2 prevents it from falling, and the cut-and-raised part 5-2 has its shoulder part 5.
-2-1 comes into contact with the upper surface of the mounting plate 4 and is prevented from falling off.

In this state, the cable 1 does not move forward, backward, left or right, but can be easily removed by lifting it upward.

The lower end 6 of the cover 6 shown schematically is attached to the presser foot from above.
-1 holds down the cable 1, so it will not fall off in any direction when the assembly is completed.

In addition, the C dimension of the receiving part 5-3 of the mounting bracket 5 is the same as that of the cable 1.
In order to receive the stopper part 2-1 of the holding fitting 2, the cut-and-raised portion 5-2 of the mounting fitting 5 is set larger than the dimension C of the holding fitting 2, and the dimension e is set larger than the dimension C of the holding fitting 2. ′.

Further, as shown in FIG. 4, the six dimensions between the stopper portion 5-2 and the receiving portion 5-3 of the mounting fitting 5 must be set slightly larger than the two dimensions of the holding fitting 2.

In this way, for example, if you try to attach a conventional transmitter and receiver with a cable to a thick flat plate, etc., it will not be possible to mount it as is, so you will need to change the holding fitting 2 to a fitting suitable for the target product. Although it had to be specially ordered, the configuration of the present invention has the advantage that it can be used as is, complete with transmitter/receiver.

In the explanations so far, the shape of the mounting bracket 5 has been described as a U-shape, but it is not limited to a U-shape, and may be L-shape, U-shape
Needless to say, other shapes that achieve the purpose of the present application are also included, as well as character shapes.

As described above, by using the present invention, it is possible to easily attach a cable to a flat plate that is difficult to bend or draw without modifying or replacing the cable with a retainer that has been conventionally used. Therefore, it has the advantage of being extremely effective and practical.
