Problems solved by technology

[0007] The purpose of the present invention is to provide a cable seal and a cable seal connector, which can solve the sealing problem caused by the large tolerance of the sheath outer diameter and cylindricity of the multi-core cable, and is especially suitable for multi-core cables with small diameter variation. The sheath of the core cable, especially the AC cable assembly, can maintain the sealing reliability of the cable connector during long-term use, and has the advantages of simpler structure and lower cost

Embodiment 1

[0042] Such as Figure 4 As shown, the cable seal of this embodiment includes an annular elastic body, the inner peripheral portion of the annular elastic body is provided with at least one cable sealing ring 21 for abutting the cable, and the outer peripheral portion of the annular elastic body At least one housing sealing ring 23 for abutting against the housing of the connector is provided;

[0043] The outer peripheries of both ends of the annular elastic body are respectively provided with recesses 24 for packaging and filling.

[0044] The recess 24 on the cable seal forms a gap that can be filled with potting material when the cable seal connector is potted. refer to Figure 5 with Image 6 As shown, when the recess 24 is filled, its bottom, side, and both ends of the annular elastic body form a pressure receiving area, that is, the sealing ring obtains the packaging pressure, thereby ensuring that the sealing ring and the connector housing and the Seal reliability ...

Embodiment 2

[0046] Based on Example 1, combined with Figure 4 , Figure 5 with Image 6 As shown, in this embodiment, the bottom angle of the side near the axial center of the annular elastic body in the recessed portion 24 is an arc angle with a radian greater than 90 degrees. In this embodiment, the depth of the recessed portion of the sealing member gradually decreases from both ends of the annular elastic body inward, so that the annular elastic body is in an irregular step shape, which optimizes the force on the recessed portion when the package is filled, and makes the sealing effect better.

[0047] Such as Figure 4 As shown, in this embodiment, one cable sealing ring is provided at both ends of the inner peripheral portion of the annular elastic body, and three outer casing sealing rings are provided at the outer peripheral portion between the concave portions at both ends. The design of the recesses at the two ends of the outer ring and the plurality of sealing rings on the...

Embodiment 3

[0052] combine Figure 3 to Figure 9 , the cable sealing connector of the present invention includes a connector housing 1 and a connector body 6, one end of the connector body 6 is fixed in the connector housing 1, and this end and the end of the cable 5 are electrically connected in the connector housing 1. connect;

[0053] Also includes a cable seal 2, a cable clamp 3 and an enclosure 4;

[0054] The cable seal 2 is sheathed between the outer periphery of the cable 5 and the connector housing 1, and the inner circumference of the cable seal 2 is provided with at least one cable seal ring 21 that can contact the cable. At least one housing sealing ring 23 that can be abutted against the housing is provided on the peripheral part; recesses for sealing and filling are respectively provided on the outer peripheries of both ends of the cable sealing member.

[0055] combine image 3 , Figure 7 with Figure 8 , the cable clamp 3 is fixed on the outer periphery of the cable ...

Abstract

The invention discloses a sealing element of a cable and a cable sealing connector. The cable sealing connector comprises a connector housing, a connector body, a cable sealing element, a cable clampand a packaging element. One end of the connector body is fixed in the connector housing and is connected with the end portion of a cable inside the connector housing. The cable sealing element is arranged between the periphery of the cable and the connector housing in a sleeving manner; and a cable sealing ring is arranged at the periphery of the inner ring of the cable sealing element and a housing sealing ring is arranged at the periphery of the outer ring. Recession parts are arranged at the peripheries of the two end portions of the cable sealing element. The cable clamp is used for fixing a cable. A cable clamp accommodation cavity is arranged in the connector housing. The packaging element includes a packaging filling part; and the shape of the packaging filling part matches the shape of an air gap among the end portion, far away from the connector body, of one end of the cable sealing element, the connector housing, the cable, and the cable clamp so as to fill the air gap. Therefore, high sealing reliability of the cable connector during the long-term application process can be kept.

Description

technical field [0001] The invention relates to the technical field of electrical connectors and sealing thereof, in particular to a cable sealing member and a cable sealing connector. Background technique [0002] In the electric vehicle charging plug and cable assembly, the cable is a multi-core cable composed of multiple wires with large diameter differences, as shown in Figure 1(a), which has large tolerances in the outer diameter and cylindricity of the sheath, and the inner filling is not full etc., resulting in a sealing problem between the cable and the connector. During long-term use, the cable is bent and twisted by external forces, and there is inevitably a relative displacement between the cable and the connector. To solve this problem, the existing technology generally uses cable sealing rings. The cable sealing rings shown in Figure 1(b) adopt a solid structure, which usually causes aging and deformation of the cables and sealing rings due to environmental fact...
