Problems solved by technology

For example, in a certain type of cable network, the tail cover of the circular electrical connector is repeatedly loosened, causing the root of the solder joint to break, which eventually leads to the quality problem of the cable breaking
For the tail cover of the circular electrical connector, there is a problem that it cannot be effectively locked, and it is easy to loosen during use, which will twist the wire bundle and cause the solder joints to be stressed.
If the cable installation space is narrow, during use, it is necessary to plug and pull and drag the wires at the rear of the connector many times, so that the stress relief margin of the tail cover is exhausted, and it is easy to force the wire contacts and cause breakage. Line and other quality problems
If potting is performed with a tail cover, the weight of the cable net will be increased, which does not meet the weight reduction requirements of the spacecraft. Therefore, it is necessary to realize the cable net without a tail cover on the basis of the current treatment process of the spacecraft cable net tail cover installed to further improve the reliability of the cable network

Embodiment Construction

[0032] The present invention will be described in detail below with reference to the accompanying drawings.

[0033] The invention can well fill the gaps between the pins of the electric connector during potting by selecting potting glue with good fluidity. Through the design of the potting mold, the potting mold and the electrical connector are fixed, and the glue is injected from the bottom of the mold to facilitate the discharge of air bubbles. The potting is completed after the glue reaches the potting height, and the gap-free potting of the high-electricity connector is realized.

[0034] The specific implementation steps follow the following principles:

[0035] a) The potting mold of the spacecraft cable net must meet the principle of sufficient exhaust, and the use of glue from the bottom of the mold is conducive to the discharge of air bubbles;

[0036] b) Easy to assemble and easy to disassemble;

[0037] c) Tight fit to prevent the glue from overflowing;

Abstract

The invention discloses a tail-cover-free embedding process of an electric connector and a testing method. According to a mould designed in the invention, glue injection is carried out from the bottom of the mould, and exhaust holes arranged at two sides of a wire hole are used for exhaust. Bubble-free embedding of the electric connector is realized, so that the requirement of insulativity of the electric connector is satisfied, and the quality of embedding is improved. The material of the mould is polytetrafluoroethylene, thereby reducing production cost of the mould. During embedding, demoulding is directly performed without coating of a releasing agent, so that a rough surface, due to uneven coating of the releasing agent, of an embedded body is prevented. According to the tail-cover-free embedding process adopted in the invention, the problem above is overcome; weight reduction is realized; tedious processing of the tail cover in the prior art is eliminated; and the reliability of a cable network is improved.

Description

technical field [0001] The invention relates to a tail-shield potting process and testing method of an aerospace electrical connector, belonging to the field of electrical connection. Background technique [0002] As the variety of satellite cable networks grows, so do the types of electrical connections and tailshields used. In the production process of cable network, the quality problems caused by the tail cover are more and more prominent. For example, in a certain type of cable network, the tail cover of the circular electrical connector has been loosened repeatedly, causing the root of the solder joint to break, which eventually leads to the quality problem of the cable breaking. For the tail cover of the circular electrical connector, there is a problem that it cannot be effectively locked, and it is easy to loosen during use, which instead causes the wire harness to twist and cause the solder joints to be stressed. If the cable installation space is narrow, during u...
