That is, when the wire 8a is inserted between the base 124a of the flexible claw 124 and the wire holding claw 142, the wire 8a must be bent or the flexible claw 124 and the wire holding claw 142 must be bent. The wire 8a is configured to have a positional relationship such that it cannot pass between the auxiliary claw 143 and the wire holding collar 142b. In other words, the wire 8a held between the base portion 124a and the wire holding claw 142 is configured so as not to easily come off.

Next, a method for forming the front cabinet 2 according to the second embodiment will be described. The molding method of the front cabinet 2 is basically the same as in the first embodiment. The front cabinet 2 is molded using an injection mold composed of a plurality of separable molds. In particular, the portion for forming the flexible claw portion 124 is, for example, a surface on the side where the first and second flange portions 124b and 124c protrude from the base portion 124a of the flexible claw portion 124 and the hole portion 124d. 1 mold, a second mold that molds the other part, and a third mold that molds the frame plate portion 21 of the front cabinet 2. Since the first and second flange portions 124b and 124c and the wire holding flange portion 142b are undercut in the flexible claw portion 124, the first mold is an inclined core.
First, the first to third molds are joined, and the front cabinet 2 is injection molded. Next, the first to third molds are separated. The first mold is separated while moving in an oblique direction with respect to the second mold and the third mold, and the first and second flange portions 124b and 124c and the hole 124d of the flexible claw portion 124 are released. To do. The amount of movement of the first mold is such that when the molded flexible claw 124 is pulled downward from between the first mold and the second mold, the hole 124d of the flexible claw 124 and the wire are held. The convex portion corresponding to the collar portion 142b may be designed to move to a position where it can pass through the second collar portion 124c without being caught by the second collar portion 124c of the flexible claw portion 124. When the first mold moves to a predetermined position, the flexible claw portion 124 is pulled down from the gap between the first mold and the second mold.

  In the video display device configured as described above, the fixing structure of the panel module 1 and the holding structure of the wires 8a can coexist in a narrower space as compared with the conventional liquid crystal television. While narrowing the frame, it is possible to hold the wire 8a that has been increased due to multifunctional functions.

  Furthermore, the flexible claw portion 124 and the wire holding claw 142 can be integrally formed at a low cost at the same time.

Furthermore, the first and second hook portions 124b and 124c are configured by a first hook portion 124b having a large area hooked on the panel module 1 and a second hook portion 124c having a small area hooked on the panel module 1. Has been.
When releasing the flexible claw 124 from the first to third molds, the first mold is removed in order to remove the first mold from the first and second flanges 124b and 124c and the hole 124d. Although it is necessary to move, since it has the 2nd collar part 124c with small amount of engagement, the flexible nail | claw part 124 can be pulled down through this part, and the movement amount of a 1st metal mold | die is made small. be able to. On the other hand, since it has the 2nd collar part 124c which ensures the amount of hooks with respect to the panel module 1, even if the movement amount of the 1st metal mold | die at the time of mold release is made small, the front cabinet 2 tends to remove | deviate from the panel module 1. The front cabinet 2 can be securely attached to the panel module 1.

  It should be understood that the embodiment disclosed this time is illustrative in all respects and not restrictive. The scope of the present invention is defined not by the above-mentioned meaning but by the scope of the claims, and is intended to include all modifications within the meaning and scope equivalent to the scope of the claims.
