Description

[Detailed Description of the Invention] This invention relates to an electric wire holder for insulating and holding electric wires, cords, etc. in the casing of electronic (air) equipment.

Electronic devices used on commercial power sources, such as TVs, tuners, and amplifiers, are connected to power cords, but according to safety standards, these cords must be fixed to electronic devices with a holding force that can withstand a certain amount of tension. I need to be there.

FIGS. 1 and 2 show an example of a structure for holding electric wires. The electric wire holder 1 has an electric wire 2 inserted therein as shown by the dotted line, and the hinge part 3 is bent. As shown in Fig. 2, the electric wire 2 is
is bent and held in an Ω shape.

However, since such an electric wire holder 1 merely meanders and holds the electric wire 2 in an Ω shape, it cannot resist the tensile force when a strong force is applied to the electric wire 2 or when the electric wire 2 is thin. There was an accident in which electric wire 2 came loose.

This idea eliminates these drawbacks and
An object of the present invention is to provide an electric wire holder that can be securely attached to a housing of an electronic device.

The electric wire holder of this invention will be explained below.

FIG. 3 is a perspective view of an electric wire holder showing an embodiment of this invention, and 11 is the main body of the electric wire holder integrally molded from synthetic resin such as nylon, with a wire holder 12 and a lid 13. They are roughly divided into two parts, and these parts are connected by a particularly thin hinge part 14.

The wire holding part 12 has an opening 15 through which the cord is inserted.
a. Two protrusions 16, 1 that make a U-turn on the cord
7, and a window hole 20 formed at the bottom, and similarly, the lid part 13 has an opening 15b through which the cord is inserted, projections 18, 19 corresponding to the projections 16, 17, and a window hole 21. is formed. Hooks 22 and 23 are formed in the window holes 20 and 21, extending from the main body 11, for fixing the main body 11 of the electric wire holder to the housing or chassis of an electronic device, as will be described later.

Note that the front side of the main body 11 of the wire holder is formed into thick parts 24 and 25, and a hole 26 is formed in the middle of the hinge part 14 to facilitate bending of the hinge part 14.

Further, wedge-shaped projections 27a and 27b are provided on each first U-turn forming portion of the wire holding portion 12 and the lid portion 13.
is formed so as to guide the electric wire C introduced through the openings 15a and 15b in a U-turn shape.

Next, a structure for holding a cord in the electric wire holder of this invention will be explained based on FIGS. 4a and 4b.

Figure 4a shows the main body 1 with the hinge part 14 opened horizontally.
1, and the electric wire (cord) C is inserted from the cord insertion opening 15a to the first plane as shown by the dotted line.
It bypasses the second protrusion 17, makes a U-turn, further bypasses the second protrusion 16, makes a U-turn, and is pulled out.

After setting the wire C in this manner, when the hinge portion 14 is bent and the lid portion 13 is placed over the wire holding portion 12, the protrusions 18 and 19 of the lid portion 13 come into contact with the protrusions 16 and 17 of the wire holding portion 12. , or come close to each other and hold the electric wire C as shown in FIG. 4b. At this time, the electric wire C is inserted into the protrusion 1 within the main body 11.
Needless to say, the parts 6, 17, 18, and 19 are locked in an S-shape.

Moreover, since the wedge-shaped protrusions 27a and 27b are formed on the first U-turn portion, even if a force pushing the electric wire C inward from the outside (in the direction B in the figure) is applied, the electric wire C will be Since it cannot be pushed into the main body 11 and the first U-turn point _U1 will not come loose, the electric wire C will not rattle.

FIG. 5 shows the main body 11 of the wire holder shaped as shown in FIG. 4b being fixed to the casing or chassis P of an electronic device.
When the main body 11 of the wire holder is press-fitted from the direction of arrow A into the hole H opened in the hole H, the wire holder 1
2. Hooks 22 and 23 formed on the lid part 13
When it passes through the hole H of the casing P, it is pushed inside, and then protrudes again due to its elasticity, and the thick parts 24 and 25 of the main body 11 and the hook 22,
23 clamps and fixes the chassis P.

Therefore, the electric wire C is locked in an S-shape within the main body 11 of the electric wire holder, and
Since the electric wire C is fixed with the hooks 22 and 23, there is no possibility of the electric wire C coming off from the electronic device.

Further, the thick parts 24 and 25 and the hooks 22 and 23 formed in the main body 11 in this way make the main body 1
1 can be fixed to the casing (chassis) P, so other attachment parts are not required and installation is easy.

Furthermore, if the lid portion 13 and the wire holding portion 12 are formed asymmetrically in size, the work of setting the wire C can be facilitated. Furthermore, protrusions 16, 17, 1
By squaring the shapes of 8 and 19, it is possible to further strengthen the ability of the electric wire C to come out.

Note that the protrusions 18 and 19 of the lid part 13 may be omitted, and as shown in FIG.
2 and the lid portion 13 may be provided with positioning bosses and boss holes 30 and 31.

As explained above, the wire holder of the present invention makes two U-turns on the wire and holds it in an S-shape, which strengthens the pull-out resistance and allows the window to move up and down avoiding the protrusions. Since it can be formed in two places, it has the advantage that fixing to the housing is simple and reliable. Furthermore, since a wedge-shaped protrusion is formed on the first U-turn forming part, even if force is applied to push the wire into the wire holder, the U-turn point of the wire will not loosen and the wire will not play. It also has the effect of preventing sticking.
