Embedment type 90-degree bent inserted PCB connector

Abstract

The invention discloses an embedment type 90-degree bent inserted PCB connector. The embedment type 90-degree bent inserted PCB connector is characterized by comprising an electrostatic dust prevention cover, a contact element, an outer shell, a rubber pad, a base, an enameled wire, a tail covering part, a gasket, an installation bolt and pouring sealant, wherein the contact element is arranged in the base adhering to the outer shell, the installation bolt is used for fixing the outer shell and the tail covering part, one end of the enameled wire is connected with the contact element in a pressed mode, the other end of the enameled wire penetrates out of the tail covering part, the pouring sealant is injected into a cavity between the tail covering part and the base, and the outer shell is covered with the electrostatic dust prevention cover. According to the embedment type 90-degree bent inserted PCB connector, a conductive wire and a pin which are integrated with the enameled wire are adopted, stickiness of the surface of the pouring sealant and the surface of the enameled wire is enhanced, the problem that the pouring sealant generates bubbles or holes is resolved, the phenomenon that the conductive wire scatters is eliminated, and the assembly technology of products is simplified. The embedment type 90-degree bent inserted PCB connector has the advantages of being simple in structure, low in cost, high in product percent of pass and reliable in quality.

Description

technical field [0001] The invention relates to the technical field of electrical connectors, a multi-node connector for connecting an interface to a printed circuit board, in particular to a potting type 90° bent-insertion PCB connector. Background technique [0002] In the prior art potting type bent-insertion PCB connector, the base is provided with a contact piece, the tail cover assembly is provided with a pin, and an inner wire is arranged to connect the contact piece with the pin. The structure of using wires to connect contacts and pins has the following problems: 1. Due to the large number of wire cores, the wires are staggered, the arrangement is messy, the space for the potting cavity is small, and the adhesiveness between the glue and the wires is poor, resulting in poor adhesion after potting. The colloid is easy to produce bubbles or voids; 2. Because the wires are short and dense, it is difficult to strip the insulation at the connection of the wires, and the ...

AI Technical Summary

Problems solved by technology

The following problems exist in the structure of using wires to connect contacts and pins: ①. Due to the large number of wire cores, the wires are interlaced and arranged in a messy manner, the space of the glue filling chamber is small, and the adhesion between the glue and the wires is poor, resulting in poor adhesion after potting. The colloid is easy to produce air bubbles or cavities; ②, because the wires are short and dense, it is difficult to strip the insulation at the wire connection, and loose wires occur at the ends of the wires, making it difficult to load the wires into the crimping barrel; The covering part 7 is in a stretched state, causing the wires on the pins to be crimped with the crimping barrel to be easily loose; ④, in the assembly process of the wires, since both ends of the wires need to be stripped, threaded, and crimped, Especially for connectors with a large number of cores, the workload is very heavy, resulting in low work efficiency

At present, there is still a structure that uses FPC flexible circuit boards to connect contacts and pins. The existing problems are: ⑤. Special flex boards need to be designed. Different core numbers and different structures need to design corresponding flex boards, resulting in flexible boards. There are many board specifications; ⑥. Since the contacts and pins need to be soldered to the flexible board one by one, the welding workload is heavy, the welding efficiency is low, and the welding quality is difficult to guarantee
