Description

[Detailed Description of the Invention] The present invention relates to a locking tool for fixing electric wires connected to electrical equipment such as connectors and relay boxes, and wire harnesses containing these wires to the case of the equipment.

When connecting a large number of wires or wire harnesses to a multi-pole connector, male terminals are crimped onto the tips of the wires and inserted into and connected to the female terminals in the connector, but the weight of the wires or wire harnesses may cause the terminals to come off. In order to prevent wires and terminals from being deformed or damaged, for example, as shown in Figure 1, hook protrusions are provided on connectors and relay box cases, etc., and flexible bands that are secured to the protrusions are used to secure cables and wires. Harnesses and the like are fixed.

In Figure 1, Figure a is a perspective view of the flexible band before it is locked to a case, etc., and Figure b is a perspective view of the flexible band when it is locked to the case and the electric wire or wire harness is fixed. In the figure, 1 is the case bottom cover fixed to the connector case body (not shown) with screws, 2 and 2 are a pair of hook protrusions with a T-shaped cross section on the bottom cover 1, and 3 is the head of the hook protrusion 2. , 4 is a support part for the hook protrusion 2, 5 is a flexible band made of synthetic resin, and 6 is a band 5 having a length approximately equal to the distance between the hook protrusions 2, 2.
, 7 and 8 are vertical plates at both ends of the main plate 6 and horizontal locking plates connected thereto, 9 is an insertion hole for the hook protrusion head 3 opened in the vertical plate 7, and 10 is opened in the horizontal locking plate 8. A slide opening for the hook protrusion support part 4, 17
indicates an electric wire or wire harness.

Alternatively, as shown in FIG. 2, a structure is used in which the relationship between the flexible band 5 and the bottom cover 1 is reversed on one side. 1 in Figure 2
2 is a hooked protrusion extending vertically or diagonally vertically at the end of the main plate 6 of the flexible band; 13 is the head of the hooked protrusion 12;
Reference numeral 14 indicates a support portion for the hook protrusion 12, 15 indicates an insertion hole for the hook protrusion head of the band provided on the bottom cover, and 16 indicates a sliding opening for the hook protrusion support portion of the band connected thereto, and the rest is the same as in Fig. 1. Codes indicate the same parts.

However, both of the devices shown in FIGS. 1 and 2 have at least a hook projection 2 on the bottom cover. This hook protrusion 2 protrudes from the bottom cover surface and is often damaged.

Moreover, the electric wires, wire harnesses, etc. fixed to the case etc. are simply held down by the main plate surface of the flexible band, and are therefore prone to wobbling.

In view of the above, the present invention has been devised to solve these problems. The example shown in FIG. 3 will be explained in detail below. Fig. 3a is a perspective view of the flexible band of the present invention before it is fixed to the bottom cover, and Fig. 3b is a perspective view of the flexible band of the present invention before it is fixed to a case etc. and an electric wire or wire harness is fixed. A perspective view of the time is shown.

In Fig. 3, 5 is a flexible band made of synthetic resin, 6 is the main plate of the band, 11 is a plate provided vertically or diagonally perpendicularly at both ends of the main plate, and 12 is similarly vertically or diagonally perpendicular to the plate 11. 13 is the head of the hook protrusion, 14 is a support portion of the hook protrusion, and 18 is a tongue piece provided horizontally at the center of the main plate. Reference numeral 1 denotes a bottom cover of the case, 15 an insertion opening for the hooked protrusion head 13 of the flexible band, and 16 a slide opening for the hooked protrusion support portion of the flexible band, which is continuous with the insertion opening 15. Further, 17 is an electric wire or a wire harness.

The method of using these is as shown in FIG.
By sliding the supporting portion through the slide opening 16, the flexible band 5 and the bottom cover 1 can be locked together. At this time, the electric wire or wire harness 17 is held and fixed between the flexible band 5 and the bottom cover 1 as in the conventional case.

In the above case, the bottom cover does not have any hook protrusions projecting from its surface, and the hook protrusions at both ends of the flexible band enter the inside of the bottom cover after attachment and do not come out to the outside. Therefore, there is no possibility that the hook protrusion is damaged as in the conventional case.

Moreover, since the tongue piece 18 is taken out from the flexible band and the electric wire or wire harness is bound (tied) thereto, the electric wire or wire harness can be more firmly fixed to the bottom cover.

According to the present invention as described above, there is no fear of damage to the hook protrusion as in the conventional case, and there is no wobbling of the fixed electric wire or wire harness.

In addition, in the present invention, the plate 11 is omitted and the cross section T
The letter-shaped hook protrusions 12 may extend directly or diagonally vertically from both ends of the main plate.

[Brief explanation of the drawing]

In perspective views showing locking devices such as electric wires or wire harnesses, Figures a and b in Figure 1 and Figure 2 are conventional ones, and Figures a and b in Figure 3 are those of the present invention. are exemplified respectively. Note that Figure a in Figure 1, Figure a in Figures 2 and 3 are views before the flexible band is fixed to the bottom cover, Figure b in Figure 1 and Figure b in Figure 3 are views of the flexible band. It is a figure after the band is locked to the bottom cover. DESCRIPTION OF SYMBOLS 1... Case bottom cover, 2... Hook protrusion, 3... Head of hook protrusion, 4...
