Problems solved by technology

[0005] (2) Use JC-311 general-purpose two-component epoxy resin glue for perfusion on the flange. This glue does not have high adhesion to metal. Under the pressure difference of 50kPa, leakage occurs, and the sealing performance does not meet the requirements.
[0006] In the process of realizing the present invention, the inventor found that there are at least defects such as uneven glue surface, easy leakage, poor sealing and low reliability in the prior art

Embodiment 1

[0048] The cable bundle flange filling and sealing method of this embodiment mainly includes:

[0049]a. Silicone rubber sealing ring is used to seal the flange that needs to be poured;

[0050] In step a, the operation of sealing the flange that needs to be poured includes:

[0051] Mill a sealing groove on the inside of the opening of the flange that needs to be poured, and fill the sealing groove with a silicone rubber sealing ring that matches the sealing groove; the thickness of the sealing groove is 2 / 3 of the thickness of the bottom of the flange left and right (for example, 1.5 / 3);

[0052] b. Through the opening on the sealed flange, pour the fluid silicone rubber into the flange in layers until the filling surface is flush with the inner surface of the flange;

[0053] In step b, the operation of pouring the fluid silicone rubber into the flange plate in layers, specifically includes:

[0054] When the thickness of each layer of perfusion glue is 2.5mm, after the ...

Abstract

The invention discloses a cable bundle flange filling and sealing method which mainly includes the steps: a, sealing a flange needing filling by the aid of a silicon rubber sealing ring; and b, filling fluid silicon rubber into the flange in a layered manner through a hole on the sealed flange until a filling rubber surface is parallel and level to the inner surface of the flange. The cable bundle flange filling and sealing method can overcome the defects of uneven rubber surface, easy leakage, poor sealing performance, low reliability and the like in the prior art, and accordingly has the advantages of even rubber surface, difficulty in leakage, fine sealing performance and high reliability.

Description

technical field [0001] The invention relates to the technical field of making electronic equipment connecting cables, in particular to a method for pouring and sealing a flange of a cable bundle. [0002] Electric cable (electric cable; power cable), usually a rope-like cable made of several or several groups of wires twisted with at least two wires in each group. Each group of wires is insulated from each other and often twisted around a center. , the entire exterior is covered with a highly insulating covering. Background technique [0003] At present, the main problems in the filling and sealing technology of the cable harness flange: [0004] (1) When Nanda 703 glue is used for plugging and pouring of the flange, the method of one-time injection is used for filling. After the glue is cured, the flange is subjected to a high temperature test at 100 ° C. After the test, it is found that the glue surface is blistered and torn. Bubble holes were found inside, indicating th...
