Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a device for fixing a power cord of a television receiver or the like.

As shown in the plan view of FIG. 1a, the front view of FIG. 1b, and the side sectional view of FIG. 1c, the general structure of a television receiver consists of a frame 1 and a back cover 2. , a chassis 3 is fixed inside, and a power cord 4 is usually pulled out from the fitting part of the frame 1 and the back cover 2 to facilitate removal of the back cover 2 during manufacturing and service.

A conventional power cord fixing device has a structure as shown in the cross-sectional view of FIG. 2 or as shown in FIG. 3. In FIG. The power cord 4 is held between the parts and fixed to the bottom of the frame with screws 6. In FIG. 3, the power cord is fitted into the groove 5b' of the cord presser 5b having an L-shaped groove 5b'. The bottom of frame 1,
It is fixed by sandwiching it with the back cover 2.

However, the fixing device shown in Fig. 2 has a structure in which the power cord 4 is fixed and the fixing device is fixed to the frame bottom 1a at the same time, and these cannot be done independently, which is not only inconvenient for work but also Since there is no structure for fixing the power cord 4 by bending it at a substantially right angle, the power cord exposed outside the fixing device must be separately bent at a right angle, which is inconvenient.

The fixing device shown in Fig. 3 has a structure in which the power cord 4 is bent at right angles to fix it, but since the power cord insertion 5b is sandwiched between the frame 1 and the back cover 2, it cannot be set with the back cover 2. If a sufficient gap l between the installation surface S and the installation surface S is not provided, the power cord 4 will be forced to bend, which is not appropriate.

Furthermore, in order to make the set compact, the power cord insertion is installed at the bottom of the chassis (including the printed circuit board) as shown at 8 in Figure 1, and the switch terminal 7
connected vertically to. For this reason, there have been problems such as damage to the power cord due to protrusions on the rear surface of the chassis when the chassis is attached and detached during manufacturing and service.

The present invention provides a power cord fixing device devised to eliminate such drawbacks.

Embodiments of the present invention will be described below with reference to the drawings in FIGS. 4 to 9.

FIG. 4 shows a plan view of the power cord fixing device of the present invention, and shows a guide groove 9a into which the power cord is inserted.
, a first portion A having protrusions 9b, 9c, 9d fixed to the bottom of the frame and a coupling protrusion 9e; a cylindrical rib 9f for shaping the power cord; a protrusion 9g for fixing the chassis; and the coupling protrusion 9e. Fitting hole 9
The second part B having a diameter h is connected by a hinge part 9i, and the first part A and the second part B are connected by the hinge part 9i
can be bent and opened/closed, and a notch 9j is formed in the hinge portion 9i. FIG. 5 is a partial perspective view showing the inside of the frame, and 10a is an F-shaped rib that supports the chassis 3, and the notch 9j is fitted into the lower leg portion 10b of the rib 10a, and the protrusion 9b, 9c and 9d are fitted and fixed into fitting portions 10c, 10d and 10e formed on the frame 1, respectively.

With the first part A and second part B of the power cord fixing device half open, the power cord 4 is fitted into the guide groove 9a and passed through the cylindrical rib 9f, then bent at the hinge part 9i, and then The connecting protrusion 9e and the hole 9h are fitted into each other, and the power cord 4 is assembled into a shape as shown in the perspective view of FIG. 6, and the power cord 4 comes out bent at a substantially right angle from the entrance to the exit.

Figures 7a to 7d are drawings showing the power cord fixing device of the present invention assembled as shown in Figure 6 and attached to the frame 1;
A side sectional view is shown.

As is clear from Fig. 7a, the power cord 4 is fixed in a dogleg shape that opens at an obtuse angle, so the power cord 4 does not move easily, has a large holding force, and Since the cord is not forcibly bent, the cord will not be damaged.
Also, the cord can be easily fitted.
Note that the distance a between the power cord fixing device and the power cord 4 is slightly smaller than the thickness of the power cord 4, and the width b is slightly larger.

Therefore, the width a is the width a when the first part A and the second part B are bent and closed at the hinge part 9i, and when the outlet of the power cord of the guide groove 9a and the position of the cylindrical rib 9f coincide with each other. The power cord 4 is also held by being held at this matching portion.

Further, the power cord fixing device of the present invention is provided with a protrusion 9g for temporarily fixing the chassis, and the chassis 3 can be temporarily fixed by fitting the protrusion 9g into the hole 3a of the chassis 3. Furthermore, the power cord 4 is covered near the outlet with a cylindrical rib 9f, and the chassis 3
This prevents the power cord 4 from being damaged by the chassis 3 when the chassis 3 is attached or detached.

When using the power cord fixing device of the present invention, the power cord 4 can be pulled out through the hole 2a and recess 2b formed in the back cover 2 and into the notch 2c, as shown in the partial perspective view of FIG. Insert. To attach the back cover 2 to the frame 1, use the hole 2d.
Pass the screw 11 through the frame 1 and tighten it into the hole 10f of the frame 1. Fig. 9 is a side sectional view showing the state in which the power cord is pulled in using the power cord fixing device of the present invention, which shows that the power cord can be pulled out in a straight line without fear of breakage, and the height of the entire set is lower than that of the conventional example. It's getting lower.

According to the power cord fixing device of the present invention, the power cord can be inserted after the power cord fixing device is fixed,
In addition, since the power cord is bent and held in a substantially right angle direction, workability is good, and since the power cord is bent and held extremely smoothly, there is an effect that no unreasonable bending force is applied to the cord. The cylindrical ribs also have the effect of preventing damage when attaching and detaching the chassis.

Furthermore, in the power cord fixing device of the present invention, a notch that fits into the leg of the F-shaped rib for supporting the chassis is provided in the hinge portion that opens and closes the first and second parts. The fixing protrusion can be used to determine the position when attaching to the frame, which not only makes installation easier, but also has a protrusion that fits into the chassis hole to fix the chassis, so a separate chassis fixing member is required. There is no need to set up
It is also advantageous in terms of the number of parts and cost.
