Embodiment Construction

[0066] An example in which the waterproof connector of the present invention is used for the relay connector 10 will be described below with reference to the drawings.

[0067] figure 1 (a) is a longitudinal section of a state before receptacle connector 20 and plug connector 30 are fitted, figure 2 It is the longitudinal section of the state after fitting.

[0068] The relay connector 10 includes a receptacle connector 20 and a plug connector 30 , each having housings 21 and 31 , a waterproof tube 70 , and a clamp housing 40 .

[0069] figure 1 (b) shows a state where the clamp housing 40 is removed.

[0070] figure 1 (a) The cable 83 and the waterproof tube 70 on the front side are cut away in order to show the fitting portion of the female housing 50 and the male housing 60 in the drawing direction inside.

[0071] Such as figure 2 As shown, in the relay connector 10 , the receptacle connector 20 and the plug connector 30 are fitted together, so that the terminal...

Abstract

The invention provides a high water-tight connector which is easily installed at the end of a cable, and a water-tight relay connector using same. The water-tight connector comprises a shell which is inserted with a terminal which is connected with the front end of a cable, a water-tight pipe which is installed by covering the peripheral region of a shell and the peripheral region of the cable, and a clamp shell which clamps the water-tight pipe from the peripheral region and can be cut into two equal parts.

Description

【Technical field】 [0001] The present invention relates to a waterproof connector and relay connector for connecting cables. 【Background technique】 [0002] Known waterproof connectors such as Figure 7 As shown in (a), the skin 183a, 193a at the end of the cable 183, 193 is peeled off, and the terminal 180, 190 is connected to the cable core wire. First, polyethylene-based synthetic rubber 121b, 131b is injected into the core portion 183b, 193b and integrally molded, and then secondary integrally molded with synthetic rubber 121a, 131a to ensure its close contact with the cable skin. [0003] This is because the adhesion between the cable skin made of polyethylene and the synthetic rubber is not good, so if the polyethylene-based synthetic rubber is not poured, the waterproofness of the casings 121, 131 cannot be ensured, which not only makes the structure complicated. And the reason for the increase of manufacturing cost, and if the housing is not integrally formed at the ...
