Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a cable fixing tool for a printed circuit board for fixing a cable mounted on a printed circuit board used in electronic equipment such as communication equipment and computers.

[0002]

2. Description of the Related Art Many cables are mounted on a printed circuit board used for electronic equipment such as communication equipment and computers. There are various mounting methods for this cable, but those using jumper wires as shown in FIG. 3 are often used. In this method, when mounting the cable 12 on the printed circuit board 11, the jumper wire 13 cut into a certain length is used to hold down the essential points of the cable 12.

Since the jumper wire 13 is covered with vinyl, it is necessary to expose both ends after cutting. This is because both ends are fixed by soldering behind the printed circuit board 11. Next, the cable 12 is sandwiched by the jumper wire 13 so as to be pressed against the printed board 11. Then, as shown in FIG. 3B (a sectional view taken along the line AA in FIG. 3A), both ends of the jumper wire 13 are projected behind the printed board 11 and fixed by soldering.

[0004]

However, in the above-mentioned conventional example, the work of cutting the jumper wire 13, exposing both ends of the jumper wire 13, soldering, etc. is required before fixing the cable 12, and various operations are required in each work. There was a problem that I had to use the tool. In addition, these operations require a lot of time, and when the jumper wires 13 are soldered, the cables 12 are loosened, and uniform fixing cannot be realized at each cable fixing point, so that the fixing work must be redone. As a result, there was a problem that work efficiency was extremely poor.

The present invention has been proposed to solve the above problems, and an object of the present invention is to provide a cable fixing device for a printed circuit board, which has a simple work process, work without using a tool, and improved work efficiency. It is what

[0006]

In order to achieve the above-mentioned object, the present invention is as follows. Formed on the printed circuit board contact surface side of the main body are a plurality of grooves penetrating from one side to the other side and opening to the printed circuit board contact surface side, and providing fixing projections on the contact surface part of the main body with the printed circuit board. It was 2. The fixing protrusions are provided at at least two positions so that the main body does not rotate in the plane of the printed board.

[0007]

In the first aspect, the cable fitting on the printed circuit board is covered with the cable fixing tool, and the cable is fitted into any of the plurality of grooves. Then, the fixing projection of the cable fixing tool is attached to the printed circuit board. Press it into the through hole and fix it. In the second item, since the two protrusions are press-fitted into the through holes of the printed circuit board, the cable fixture is fixed in a stable state.

[0008]

An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view of a printed circuit board 1 and a cable fixture 2. Cable fixture 2 as shown
Has a main body 2a formed into a flat and substantially rectangular body.
A plurality of grooves 3 in different directions are formed on one side of a (on the side that contacts the printed circuit board 1). The groove 3 penetrates from one side portion to the other side portion of the main body 2a and is open on the side of the contact surface with the printed circuit board 1. Moreover, the groove 3 direction is formed so as to match the longitudinal direction, the lateral direction, the diagonal direction, and the direction in which the cable extends. The depth and width of the groove 3 may be formed to be substantially the same as the cross-sectional diameter of the cable. Further, in order to fix a plurality of cables at the same time, the groove 3 may be formed to have a large depth or width.

When the cable fixture 2 is formed in this way, the side surfaces of the main body 2a that contact the printed circuit board 1 are formed by gathering the deformed surfaces separated from each other. In the drawing, the appearance is as if the triangular surfaces were aggregated. The dowels 4a, 4a,
4b is provided. The dowels 4a and 4b are press-fitted into through holes of the printed circuit board 1 which will be described later, and the cable fixture 2
Since the cable fixture 2 is stably placed on the printed circuit board 1, the dowel 4 is placed at a position where the cable fixture 2 is stably placed on the printed circuit board 1.
a, 4b must be provided (in the drawing, the main body 2a
The dowels 4a, 4 at two diagonal positions on the contact surface of the
b is provided).

It should be noted that it would be advantageous in terms of production efficiency to form the entire cable fixture 2 from synthetic resin. Also, the shape of the main body 2a of the cable fixing tool 2 may be more smoothly attached and detached by applying a non-slip process to the side portion that is a portion to be gripped by a finger or forming a protrusion for finger hanging. Also, if the portion of the main body 2a that is pushed by the finger, which is the back portion, is formed as a gentle protrusion, it will be easier to push.

The operation of the present embodiment thus constructed will be described. The cable is mounted on the printed circuit board 1 as follows. First, the cable is bent in a desired direction so as to be aligned with the surface of the printed circuit board 1, the cable fixture 2 is applied so as to cover the cable, and at the same time, the cable is fitted into the groove 3. In this case, which groove 3
Whether to insert the cable into the cable depends on the extension direction of the cable. When the cable is settled at the proper position in this way, the dowels 4a and 4b of the main body 2a are press-fitted into the through hole 1a of the printed circuit board 1 so that the cable fixture 2 can be fixed at the same time. Although FIG. 2 shows a state in which the cables are thus fixed, a plurality of cable fixing tools 2 will be used if necessary. Further, since the through hole 1a is formed over the entire surface of the printed circuit board 1, it goes without saying that the cable fixture 2 can be installed at an appropriate location.

[0012]

As described above, according to the present invention, the cable 5 is simply pressed against the printed circuit board 1 and sandwiched between the cable fixing tools 2 so that the cable can be fixed easily and quickly without using any tools. Work can be carried out. Moreover, the cable fixture 2 can be fixed only by press-fitting the dowels 4a and 4b provided on the main body 2a into the through hole 1a of the printed circuit board 1, so that it is necessary to process and solder the cable 5 as in the conventional case. do not do. Therefore, it is possible to reduce the number of parts processing operations and the number of assembly steps. Further, since the plurality of cable fixtures 2 prepared in advance are simply press-fitted into the printed board 1, the cable 5 can be fixed in a uniform state at any fixing place. Further, since the cable fixture 2 is attachable to and detachable from the printed circuit board 1, it goes without saying that the fixing point of the cable 5 can be changed and the cable 5 can be detached.
