Abstract

PURPOSE:To see that a fastening cap, etc., are needless, that the number of components is small, that the mold structure is simple, and that the mold can be made cheaply by molding resin in a resin tube so as to form a tube holder. CONSTITUTION:A cable 1 is installed in a mold being made in the shape of a cable holder 4, and thermoplastic synthetic resin is injected into this mold as the molding material of the cable holder 4, and it is hardened. Hereby, a cable holder 4 for the cable 1 is molded with a resin mold.

<Prior Art and its Problems> Conventionally, for example, there is a cable holding device for electronic equipment as shown in FIG. This is an outlet formed in the cable holder 101 made of synthetic resin, which is made up of an electronic device case, etc. 02 and the cable 103 led out from this outlet 102, a rubber bush 104 is inserted into the cable +03, and a tightening cap +05 inserted into the cable +03 is attached to the cable holder lot. It is pushed into and fitted into an annular engagement protrusion 106 formed in the.

However, with such conventional ones, the rubber bush +0
4 and the tightening cap 105, the number of parts is relatively large.
3, there is also a drawback that the insertion work is time-consuming because the sliding between the two 103 and 104 is poor. In order to improve the above-mentioned slippage, it is necessary to apply alcohol, powder, etc. to the outer surface of the cable +03. Furthermore, the tightening cap +05 is attached to the engaging protrusion 106 on the cable holder 101 side.
Because of the structure in which these parts are fitted, the mold for molding them becomes complicated and costs increase.

Become. In particular, since the resin tube is flexible, it deforms following the sink marks during molding of the tube holder, so that liquid tightness between the two can be ensured without using a rubber bushing or the like.

In the figure, 1 is a cable in which a core wire part 3 is covered with a sheath part 2 as a resin tube, and the sheath part 2 is made of synthetic resin whose main component is vinyl chloride (PVC). The one given is used. For example,
There is S-Flex [product name/product electric wire ■]. Reference numeral 4 designates a cable holder molded onto the cable 1 using a resin mold.

The cable holder 4 is formed as follows. First, a mold (not shown) that formed the shape of the cable holder 4
When the cable 1 is placed inside the mold, thermoplastic synthetic resin is injected into the mold as a molding material for the cable holder 4, and this is cured, the cable 1 is covered with resin as shown in FIGS. 1 and 2. The cable holder 4 is molded.

By the way, in general, there is a tendency for a gap to occur between the cable l side and the cable holder 4 side due to resin sink marks during molding of the cable holder 4. However, since the jacket part 2 of the cable l is flexible as a resin tube, the jacket part 2 follows the sink mark of the molded resin 4 as shown by the dotted line in FIG. is in close contact. In particular, by specifying the outer sheath 2 of the cable 1 and the molding material of the cable holder 4 as described above, the two 1.4 are completely bonded, and this is possible even when thermal shock or mechanical stress is applied.
