A sealed detachable electrical connector

Abstract

The invention discloses a sealed and detachable electrical connector, which comprises a housing and a transfer pin arranged inside the housing, a locking ring, a pin, a pressure ring, a cable locking component, and a fixing ring. On the connecting pin, the pin is divided into a pin head, a pin flange and a crimping barrel which are sequentially connected as a whole. The pin head is connected to the lower part of the rotating pin, and the pressure ring is placed under the pin flange. And it is empty on the outside of the crimping barrel. The cable locking assembly is located under the crimping ring and fixed by the fixing ring. There is also an O-ring A between the outside of the adapter pin and the inner wall of the shell, and an O-ring is set on the outside of the shell. Ring B. The connector can be truly sealed and detachable, ensuring that after the connector contacts are mated or removed, the inside and outside of the equipment installed by the connector can be kept sealed and isolated, ensuring that the inside of the equipment will not be polluted, and improving the overall durability of the equipment. environmental performance.

Description

technical field [0001] The invention belongs to the technical field of connectors, in particular to a sealed detachable electrical connector. Background technique [0002] At present, electrical connectors with detachable contacts usually use spring coils or stab structures to fix the contacts on the insulator. There is a large gap with the contact piece, so that the product structure cannot realize the sealing function. [0003] In the existing common technology, in order to achieve a better sealing function, the electrical connector generally uses glass sintering or potting sealant as the insulator, and the contact is fixed to the housing through the above-mentioned insulator. Although the above-mentioned structure can achieve sealing, However, the contact parts cannot be disassembled. When individual contact parts are damaged, the product cannot be reworked and repaired, and the product is scrapped as a whole, resulting in great waste. [0004] Therefore, conventional c...

Problems solved by technology

[0002] At present, electrical connectors with detachable contacts usually use spring coils or stab structures to fix the contacts on the insulator. There is a large gap with the contact parts, so that the product structure cannot realize the sealing function

[0003] In the existing common technology, in order to achieve a better sealing function, the electrical connector generally uses glass sintering or potting sealant as the insulator, and the contact is fixed to the housing through the above-mentioned insulator. Although the above-mentioned structure can achieve sealing, However, its contact parts cannot be disassembled. When individual contact parts are damaged, the product cannot be reworked and repaired, and the product as a whole is scrapped, resulting in great waste

[0004] Therefore, conventional connectors generally cannot take into account the two functions of sealing and detachment at the same time, but with the development of connector technology, some special connectors that can basically achieve sealing and detachment have appeared.

For example, the Chinese patent with the publication number CN109149208A discloses a sealing structure between the detachable contact piece and the insulating base of the electrical connector. The O-ring can be used to achieve sealing, but this type of structure can only compress the O-ring to achieve sealing after the contact is installed. When the contact is not assembled, the assembly hole of the insulator contact will pass through, and the fundamental seal cannot be achieved.
