[Detailed description of the invention] This invention is a cord for a board that is used to attach a cord for conducting electricity in various electronic or electrical equipment to a board fixedly provided in those equipment. This relates to the structure of the fastening part.

The purpose of this is to make it easy to fasten the cord to the board, and even if the board is thick or thin, the same fastening member can be used to fasten the cord. It is an object of the present invention to provide a structure of a cord fixing part to a board, which makes it possible to perform the following operations.

The drawings showing the embodiments of the present application will be described below.

In FIG. 1, reference numeral 1 denotes a case, which is a case for electronic equipment such as a community reception device, an amplifier, a power supply device, an intercom device, or a case for other electrical equipment.

Reference numeral 4 indicates a fastener used in a portion for pulling out the cord 2 from the case 1.

Next, in FIGS. 2 to 5 showing the fastener 4 in detail, reference numeral 5 indicates a substrate, which constitutes the side wall of the case.

Reference numeral 6 indicates a through hole drilled in the substrate 5.

Next, the fastening tool 4 is composed of a stopper main body 7 and a locking body 8.

First, in the stopper main body 7, reference numeral 9 denotes a base, which is formed to have a thickness that allows it to be inserted into the through hole 6.

Further, this base body 9 is constructed integrally with the covering of the cord 2.

Reference numeral 10 denotes a protection part formed by a part of the base body 9, and is a part provided to prevent the cord 2 from being broken when the cord 2 is bent.

Reference numeral 11 indicates a flange piece formed in a projecting shape from the outer periphery of the base body.

Reference numeral 12 indicates a penetration portion that passes through the through hole 6 in the base body 9.

Reference numeral 13 indicates a fitting groove, which is formed in a portion exposed through the through hole 6 of the substrate 5 so as to be parallel to opposite sides of the base body 9 (the upper side and the lower side in FIG. 2).

The stopper main body 7 is generally made of vinyl chloride resin.

Further, the stopper main body 7 may be made of a hard material or a soft material.

That is, if it is made of a hard material, the cord 2 can be firmly attached to the substrate 5.

When forming such a hard material, ABS resin or epoxy resin is used.

In addition, if the cord 2 is formed to be soft, it will be more responsive to the differences in the fitting groove 13 (width variations) when inserting the fitting member, which will be described later. It can absorb that unnecessary power.

When forming the material to be soft like this, polyethylene resin, silicone rubber, or the like is used.

Further, the stopper main body 7 and the cord 2 are connected by, for example, insert press-fitting or integral molding.

Next, in the locking body 8, reference numeral 14 is a fitting member, and the pair is arranged parallel to each other as shown in FIGS. 3 and 4 so that it can be fitted into the pair of fitting grooves 13. .

Reference numeral 15 indicates a connecting piece that connects both fitting members 14.

Reference numeral 16 denotes a pressing member, which is attached to the opposite side of the opposing sides of the pair of fitting members 14, respectively.

As clearly shown in FIG. 2, this pressing member 16 is formed to have a thickness larger than that of the fitting member 14.

Further, in this pressing member 16, reference numerals 17 and 18 indicate pressing surfaces, respectively.

These pressing surfaces 17 and 18 are connected to the fitting member 14 of the pressing surface 17.
Dimension of protrusion from (the dimension of protrusion in the axial direction of the base body 9 in the stopper body 7 when the locking body 8 is coupled to the stopper body 7)

Note that the above-mentioned direction is referred to as both fitting members 14 in this specification.
(also referred to as a direction perpendicular to the virtual plane containing the surface) is larger than the protrusion dimension of the pressing surface 18 from the fitting member 14 (in this example, they are on the same plane and the protrusion dimension is zero). It is.

The locking body 8 as described above is formed by punching out a metal plate using a press, or is formed using a hard synthetic resin material.

Next, the operation of fixing the cord 2 to the board 5 using the fixing tool having the above structure will be explained.

First, the stopper main body 7 fixed to the cord 2 is attached to the protective part 1.
The collar piece 11 is inserted into the through hole of the substrate 5 from the side opposite to the side opposite to the side of the substrate 5, and the flange piece 11 is placed along one surface of the substrate 5.

Thereafter, as shown in FIG. 4, the U-shaped locking body 8 is moved in the direction of the arrow 19 along the surface of the substrate 5, and the pair of fitting members 14 are inserted into the pair of fitting grooves 13. do.

As a result, the board 5 is held between the flange piece 11 and the pressing surface 18 of the pressing member 16, and the cord 2 is fixedly attached to the board 5.

In the above case, since the stopper main body 7 is made of relatively flexible vinyl chloride resin, the thickness of the substrate 5 may be slightly thicker, or the fitting member 1 may be wider than the width of the fitting groove 13.
Even if the thickness of 4 becomes slightly large, insertion in the direction of arrow 19 is possible.

Next, fix the cord 2 to the thin board as shown in drawing 5.
This will be explained based on the diagram.

When the substrate 5' is thin as shown in FIG.
After inserting the stopper body 7 into the through hole 6' in the same manner as described above, turn the locking body 8 upside down and insert the fitting member 14 into the fitting groove 13 in the state shown in the figure. do.

As a result, the board 5' is held between the flange piece 11 and the pressing surface 17 having a large protruding size, and even in this case, the cord 2 can be securely fixed to the board 5.

Note that the locking member 8 having the above structure is strong because the pressing member 16 is formed thickly, so even if the fitting member 14 is thin, the pressing member 16 reinforces the fitting member 14 and the locking member 8 is strong. becomes.

Next, FIG. 6 shows a different embodiment of the present application, in which a storage battery 22 and a DC-AC
The cord 24 connecting to the converter 23 is connected to the storage battery 2.
This figure shows an example in which the fastener 4e is used to fasten to a partition plate 25 for partitioning a room in which a DC-AC converter 2 and a DC-AC converter 23 are installed.

It should be noted that parts that are functionally the same or equivalent to those in the previous figure are given the same reference numerals and the letter e as in both figures, and redundant explanations are omitted.

(In addition, the same idea applies to the explanations after the origin, and the letter f is added to omit duplicate explanations.

) Next, FIGS. 7 to 10 show further different embodiments of the present application.

In this example, the base 9f is formed in a non-round shape as shown in the figure, and the through hole 6f formed in the substrate 5f is also formed in a corresponding shape.

Therefore, rotation of the stopper 7f with respect to the substrate 5f is prevented.

Numeral 30 indicates a large number of grooves, which are provided to increase the flexibility of the protective portion 10f.

Further, FIG. 7 shows an example of a thick board in which a panel board 26 is stacked on a board 5f, and FIG. 10 shows an example in which the panel board 26 as described above is not used as an example of a thin board. It is.

As is well known, an aluminum plate, a synthetic resin plate, or the like is used as the panel plate 26.

Furthermore, in the locking body 8f in this example, the fitting member T4
A retaining piece 27 is formed at opposing portions at the tip of f, so that when the locking body 8f is coupled to the stopper body 7f, the locking body 8f may inadvertently fall off the stopper body 7f.
This is to ensure that it does not deviate from f.

Further, in this locking body 8f, an introduction part 29 is formed at the tip of the fitting member 14f, and when changing from the state shown in FIG. 9 to the state shown in FIG. 8, that is, the fitting member 14f This is so that the insertion can be easily performed when inserting into the fitting groove 13f.

The insertion force is, for example, about 1 kg.

Also, due to the presence of the retaining piece 27, the fitting groove 1 of the locking body 8f
For example, about 4 kg of force is required to pull it out from 3 f.

Furthermore, this locking body 8f is formed by punching out a metal plate using a pressing means, so that a part thereof is bulged out as shown in FIG. 7 or FIG. 10, and one surface of the bulged portion 28 is a pressing surface. 17 f.

As described above, in this invention, the stopper main body 7 fixed to the cord has a pair of fitting grooves into which the pair of fitting members 14 of the U-shaped locking body 8 can be inserted. 13
Since the structure is equipped with the code 2 for the board 5,
When fastening, insert the base 9 of the stopper body 7 into the through hole 6 of the substrate 5, and then insert the fitting member 14 of the locking body 8.
The above-mentioned fixing operation can be carried out extremely simply by simply inserting the stopper body 7 into the fitting groove 13 of the stopper main body 7.

Moreover, in the present invention, the pressing member 1 in the locking body 8
The dimension in which 6 protrudes from the fitting member 14 (the dimension in which it protrudes from a virtual plane including both fitting members in a direction perpendicular to that plane) is as shown in FIG. 2 or 5.
Since the one side and the other side are different from each other, in the above case, even if the thickness of the board 5 is thick or thin, the same stopper, main body 7 and locking body 8 can be used to secure the cord. It also has the effect of showing wide adaptability.
