Cable holder and cable connecting device including the same

Technical Field

The present invention relates to a cable holder and a cable connecting device including the same, and more particularly, to a cable holder combined to an outer circumferential surface of a cable for transmitting a signal or power in an automobile to fix the cable and a cable connecting device including the same.

Background

A plurality of cables are arranged inside the automobile to transmit power, signals, and the like. At the end of the cable is incorporated a cable connection device comprising a connector providing a connection interface with a power supply or a sensor or the like.

A cable connection device disposed in an automobile also has a sleeve for preventing moisture, foreign matter, and the like from entering the inside of the connector. The sleeve surrounds a connection site between the cable and the connector in a state where the connector and the cable are connected.

The sleeve may be formed by injection molding. The injection molding mode can be beneficial to ensuring the sealing force of the sleeve. However, the molding material enters the inside of the connector during the process of forming the sleeve, with the problem of causing defects or degrading performance of the connector.

In order to solve such a problem, a method of additionally disposing a cable sealing member in the connector housing has been proposed. However, there is a fact that there is always a problem that the appearance of the product is deteriorated or the quality is degraded while the cable sealing part is pushed by the injection pressure when the sleeve is injection-molded.

holes

12a and 12b, and is press-fitted into the mounting

holes

12a and 12 b.

If cable holder 20 is formed of a single member, in order to pass first cable 100a and second cable 100b through the holder, the end portions of first cable 100a and second cable 100b need to pass through the first through hole and second through hole of cable holder 20. Accordingly, the process of coupling the cable holder 20 to the first and

second cables

100a and 100b is necessarily troublesome.

However, according to the embodiment of the present invention, the first holding member 21 and the second holding member 22 disposed across the middle section portions of the first cable 100a and the second cable 100b are coupled, and the cable holder 20 can be coupled to the

cables

Referring to fig. 9, in an embodiment of the present invention, the cable holder 20 has a shape in which any one of the lengthwise one side and the other side can be inserted into the mounting

holes

12a, 12 b. That is, as described above, in the case of the embodiment of the present invention, it is not necessary to consider the vertical and horizontal directions of the first holding member 21 and the second holding member 22 when assembling the cable holder 20. Accordingly, the manufacturing efficiency can be greatly improved under the condition of the embodiment of the utility model.
