Embodiment 1

[0037] In Embodiment 1, the axial bending of the inner liner is arc-shaped, so that the support is arc-shaped. Further, among the three parts of the two ends and the middle of the arc-shaped support, any one part is located at a different position from the other two parts. In a two-dimensional plane, in order to meet the requirements of conforming to the structure of the seal.

Embodiment 2

[0038] In embodiment 2, the inner liner is axially bent in a spiral shape. Further, each winding groove is spirally arranged along the outer periphery of the inner liner. There are 12 winding grooves arranged on the outer periphery of the inner liner. The spacing is set, and the 12 winding slots correspond to 12 metal wires to form a complete support and cooperate with the inner lining to strengthen its structural strength.

Abstract

The invention discloses a wire wrapping support sealing piece. The sealing piece constitutes a sealing linker between a cable and a structure piece, and comprises a liner piece, a wrapping piece and multiple support pieces, wherein the radial cross section of the liner piece is in a closed annular shape; the periphery of the liner piece is provided with multiple wire wrapping grooves, the two endsof each wire wrapping groove extend to the two ends of the liner piece respectively, and the periphery of the support pieces and the liner piece is wrapped with the wrapping piece; each support pieceis connected to the periphery of the liner piece in a wrapping mode along single wire wrapping groove separately. In the wire wrapping support sealing piece, the support pieces are winded closely andabreast into a support body, the support body formed by winding multiple metal wires closely has a support skeleton structure which can ensure that the liner piece and the wrapping piece do not deform in the conditions of external extrusion force and the like, and the defect of shortened service life caused by self aging and deforming of the liner piece and the wrapping piece is overcome; meanwhile, a high-elastic plastic material like plastic and rubber can be adopted in the liner piece and the wrapping piece and has a good gap sealing performance.

Description

technical field [0001] The invention relates to the technical field of nodule sealing of electrical connectors, and belongs to the technical field of cable sealing. Background technique [0002] At present, the role of seals is to make the seal between objects more firm and stable, so they are widely used, especially in the electronic field. [0003] Existing cable seals are mainly made of conventional high-elastic materials such as rubber. In the subsequent use process, when the joint moves or vibrates, it is difficult for the conventional sealing structure to ensure long-term stable sealing. For example, after the cable is connected to the equipment, there is a sealing problem between the outer circumference of the cable and the equipment. In the further long-term use process, due to the inevitable relative displacement, vibration, etc. between the cable and the equipment, ordinary sealing rings, sealing strips, etc. Due to aging and deformation, etc., it has been difficu...
