Encapsulation fixture and method for accurately controlling wire diameter of cable fixing section by adopting same

Abstract

The invention provides an encapsulation fixture and a method for accurately controlling the wire diameter of a cable fixing section by adopting the same. The problems that in the prior art, when a cable fixing section is machined, the wire diameter is difficult to control, and dimensional tolerance is unqualified are solved. The encapsulation fixture comprises a first semi-cylinder and a second semi-cylinder which are symmetrically arranged; in addition, the invention provides a process method for accurately controlling the wire diameter of the cable fixing section by adopting the encapsulation fixture. The method includes the following steps of: encapsulating a cable at the periphery of a pre-processed fixed section cable by adopting the encapsulation fixture, opening the fixture after glue solution is solidified, cleaning the overflowing glue solution at the periphery, and blowing a die shrink sleeve at the periphery of the encapsulating glue to finish processing. According to the method, the wire diameter size of the fixed section is well controlled under the condition that the functional performance, wear resistance, high temperature resistance and other environmental performance of the cable are not affected; the processing technology is convenient and fast, and is not influenced by the wire diameter size of the cable and artificial processing errors.

Description

technical field [0001] The invention belongs to the technical field of cable processing, and relates to a potting fixture and a method for precisely controlling the wire diameter of a fixed section of a cable by using the fixture. Background technique [0002] With the development of cables, the requirements for cable installation in the industry are getting higher and higher. Adding a fixed section to the cable is a way of clamping the cable during installation. The installation of the cable, especially in the complex vibration environment, has higher requirements for the cooperation here, so for the cable, controlling the wire diameter of the fixed section has become a trend to improve the cable installability. [0003] The existing processing method of the cable fixing section is generally to apply potting glue inside the mold shrink sleeve of a special-shaped part, and shrink it on the cable after blowing. The mold shrink sleeve after blowing is cylindrical. The shrink ...

Problems solved by technology

[0003] The existing processing method of the cable fixing section is generally to apply potting glue inside the mold shrink sleeve of a special-shaped part, and shrink it on the cable after blowing. The mold shrink sleeve after blowing is cylindrical. The shrink sleeve itself has a certain shrinkage range, and is also affected by the wire diameter of the cable where it is located. The wire diameter tolerance requirement before shrinking has reached 0~+2mm or even 0~+1mm. There is an error in the cable wire diameter itself, and it is difficult to control whether the cable is round when the wire diameter is corrected. It is difficult to predict whether the fixed section after blowing shrinks. Within the tolerance range, it is very difficult to control the wire diameter of the fixed section

In addition, if the fixed section is unqualified after the cable is blown, it needs to be removed and reprocessed with a new fixed section, resulting in waste
