Anti-scooping connector plug, anti-scooping connector socket and connector assembly

Abstract

The invention relates to an anti-scooping connector plug, an anti-scooping connector socket and a connector assembly, the anti-scooping connector plug comprises a plug insulator and a contact pin arranged in the plug insulator, the socket comprises a socket insulator and a jack arranged in the socket insulator, a pit is arranged on the opposite plugging surface of the plug insulator, and the plug insulator and the jack are arranged in the pit. The contact end of the contact pin is arranged in the pit, the pit is internally provided with a limiting part, the limiting part is higher than the contact pin in the plugging direction of the anti-scooping connector plug, by means of the technical scheme, the anti-scooping connector plug enables the limiting part to realize an anti-scooping function in the process of oblique plugging of the head seat, and the contact pin is prevented from being bent by a socket insulator during oblique plugging.

Description

technical field [0001] The invention belongs to the technical field of connectors, and particularly relates to a scoop-proof connector plug, a scoop-proof connector socket and a connector assembly. Background technique [0002] During the mating process of the connector user, due to some uncontrollable factors, it often occurs that the connectors at both ends of the header are inserted obliquely when the connectors at both ends of the header are not aligned. like figure 1 , when the pin contact piece 001 in the plug 01 and the jack contact piece in the socket 02 are inserted obliquely, the plug-in connector forms a scooping action, and the pin contact piece 001 collides with the socket insulator 002 ( figure 1 The middle P area is the collision area), at this time, it is very likely that the pin contacts arranged inside will be bent. At present, the overall shape of the existing similar circular connector products is circular, and the error prevention during the plug-in pr...

AI Technical Summary

Problems solved by technology

At present, the overall shape of the existing similar circular connector products is circular, and the error prevention during the mating process of the head seat is realized by the key position, and the scoop prevention is realized by increasing the depth of the insulator; currently there are similar rectangular connector products ,like figure 2 , Error prevention is mostly achieved through the guidance and cooperation of guide pins and guide grooves, and anti-scooping along the length of the connector is difficult to achieve; avoiding this situation in structural design is called anti-scooping design

[0003] The disadvantages of the existing circular connector structure are as follows: 1. Mistake-proof installation is realized through the cooperation between the key and the keyway, but this feature is not easy to guide in actual mating use, and a more accurate alignment is required in advance. positive, to achieve a smooth installation

2. The contact parts are scattered and arranged, so it is required to install the contact parts one by one, and it is impossible to install multiple contact parts at the same time through the material tape

3. The overall size of the product is small. In order to facilitate the welding of wires and leave enough room for operation, the arrangement of contacts can only be made into two rows. The connector has a total of 12 cores, and each row needs to arrange 6 contacts; Electrical distance, there must be enough gaps between the contacts, and then made into a circular shape, one is not beautiful, and the other is that the overall size will be too large, which cannot meet the requirements

5. Anti scooping is achieved by lengthening the insulator, the insulator often sinks deeper, and the product size will be longer

[0004] The disadvantages of the existing rectangular connector structure are as follows: 1. Mistake-proof installation is mostly achieved through asymmetric guide pins, and also through local features to ensure mistake-proof. In actual mating installation, a more precise installation is also required. Positive

At the same time, one end of the guide pin column will be a longer cantilever beam structure with lower strength

2. When the contacts are arranged in two rows, each row needs to be arranged with 6 contacts. At this time, the size in the horizontal direction is longer, and the anti-scooping function cannot be realized. At the same time, the size of the contacts is small, and it is very easy to bend the contacts when inserting them.
