An integral potting type 90° bend plug PCB connector

Abstract

The invention discloses an integrally-poured 90-degree bending and inserting type PCB connector. The PCB connector comprises a static dust cover, a housing, a contact part, a base, a pin, a cushion board, a conductor, a pouring sealant, a mounting screw, an insert nut, a rubber cushion and a pouring die; the housing, the contact part, the base and the pin are arranged in the pouring die; the base, the insert nut, the contact part, the pin and the conductor are integrally poured by the pouring die through the pouring sealant; the static dust cover covers the outer side of the housing. According to the integrally-poured 90-degree bending and inserting type PCB connector, the structure that the contact part and the pin are connected through the conductor and the pin is directly fixed through the pouring sealant is adopted, so that the defect that the sealant is separated from a tail covering part can be solved; the PCB connector has the advantages of being simple in process and high in working reliability.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, in particular to an integrally potted 90° curved insertion PCB connector. Background technique [0002] The potting type curved plug PCB connector in the prior art mostly adopts the structure that the contacts and the pins are respectively installed on the base and the tail cover assembly. The circuit boards are connected, and the second is to replace the wires and pins with enameled wires, that is, the enameled wires are installed on the tail cover as pins and connected with the contacts as wires. [0003] The existing problem is: because the connector has been working in a high temperature and vibration environment for a long time, the potted colloid and the plastic shell of the tail cover are separated and the colloid is cracked. The reason is that the heat shrinkage ratio of the colloid and the tail cover material is different. , coupled with the long-term high temperature work...

Problems solved by technology

[0003] The existing problem is: because the connector has been working in a high temperature and vibration environment for a long time, the potted colloid and the plastic shell of the tail cover are separated and the colloid is cracked. The reason is that the heat shrinkage ratio of the colloid and the tail cover material is different. , coupled with the long-term high-temperature working environment caused the separation and colloidal cracking between the two

The separation of the colloid and the tail cover makes the connector only fix the tail cover in actual work, but the pins and the colloid of the connector are not fixed, which will lead to poor contact of the connector in the working environment of high temperature and vibration, which will directly affect the product work reliability

[0004] As for the structure connecting the contacts and the pins through the FPC flexible circuit board, this structure needs to design a special flex board with different core numbers, resulting in too many varieties and specifications of the flex board, which is not conducive to the mass production of the flex board. , soldering is required between the pin and the flexible board, the soldering workload is heavy, the efficiency of manual soldering is low, and the soldering quality is difficult to guarantee;

[0005] For the structure of replacing wires and pins with enameled wires, this structure needs to use molten caustic soda solution to remove the paint on the ends of the enameled wires. After removing the paint, it needs to be neutralized with acid and alkali. , there are many process steps and it is very difficult to realize
