Problems solved by technology

[0004] However, when the connector does not have a matching tail cover or the tail cover cannot be installed due to space constraints, the cable is pulled or otherwise in a vibrating environment, the cable, welding, and connector are subjected to external forces at the same time, and the weakest welding is very easy to break. Failure under the action of external force, resulting in the failure of the normal use of the cable

Embodiment 1

[0036] The connector potting method of the present embodiment comprises the following specific steps:

[0037] S1. Decontamination: Clean the connectors to be potted and the potting mold with absolute ethanol, and dry them; the potting mold is made of silicone rubber material, and the Shore hardness of the potting mold is 30 degrees.

[0038] Before potting, decontaminate the connectors and potting mold first, which can improve the adhesion between the potting glue and the connectors in the later stage, reduce the peeling rate of the potting glue, and avoid the stains in the potting mold from affecting the potting process. influences.

[0039] S2. Assembling: insert the connector into the potting mold and limit the overall position, and arrange the cables connected to the connector at the same time, and adjust the cable to be located in the middle of the potting mold.

[0040] The middle part here should be understood as leaving a relatively uniform gap between the cable and ...

Embodiment 2

[0050] The connector potting method of the present embodiment comprises the following specific steps:

[0051] S1. Decontamination: Clean the connectors to be potted and the potting mold with absolute ethanol, and dry them; the potting mold is made of silicone rubber, and the Shore hardness of the potting mold is 45 degrees.

[0052] S2. Assembling: insert the connector into the potting mold and limit the overall position, and arrange the cables connected to the connector at the same time, and adjust the cable to be located in the middle of the potting mold.

[0053] S3. Adjust potting glue: take potting glue main agent, toughening agent and thickener and mix evenly, make potting glue after fully stirring; wherein said potting glue main agent includes bisphenol A type epoxy resin, The toughening agent includes dibutyl phthalate, and the toughening agent accounts for 10% of the mass of the main potting adhesive, and the thickener accounts for 7% of the mass of the main potting ...

Abstract

The invention discloses a connector assembly encapsulation method which comprises the following steps: a connector assembly to be encapsulated and an encapsulation mold are cleaned with absolute ethanol and dried; the connector assembly is sleeved into the encapsulation mold and the whole is limited, and the cables connected on the connector assembly are arranged; an encapsulation glue main agent,a toughening agent and a thickening agent are uniformly mixed and fully stirred to obtain the encapsulation glue; the encapsulation glue is poured or injected into the encapsulation mold until the encapsulation glue completely covers the bottom of the area to be encapsulated; when the encapsulation glue completely covers the bottom of the area to be encapsulated, the encapsulation glue is continuously poured or injected into the encapsulation mold until the encapsulation glue is leveled with the opening of the encapsulation mold; after the end of encapsulation, the encapsulation glue is leftto be cured at room temperature; and after the solidification glue is cured, the whole limiting on the connector assembly and the encapsulation mold is released, the encapsulation mold is stripped andthe connector assembly is taken out. The method can remarkably improve the connection reliability and stability of the connector assembly and the cable, and the encapsulated glue is not liable to crack and detach.

Description

technical field [0001] The invention belongs to the field of connector reinforcement, and in particular relates to a connector potting method. Background technique [0002] As an intermediate link connecting various functional modules of the entire electronic system, cables are widely used in the fields of ordinary electronic equipment and aerospace, and the stability of their performance is particularly important. The cable is generally assembled by welding the cable and the connector. The cable is composed of a core wire and an insulating sheath. The connector generally adopts an integrated design. One end of the connector is connected to the cable, and the other end is connected to the socket. The welding joint between the cable and the connector is connected by solder. The reliability of the weld between the two is far lower than that of the cable and the connector itself, and it is the weakest link of the entire cable. Such as figure 1 Shown is a schematic diagram of...
