[0046] The first embodiment: as Figure 1 to Figure 10 As shown, a secondary locking device guarantee system for connectors includes a connector socket housing 1 and a connector plug housing 2 that are mated with each other. Two fixing columns 201 are arranged on both sides of the connector plug housing 2. One The lock main body 3 rotates and cooperates with the two fixing columns 201 through the two positioning holes 301 on both sides. The two guide columns 101 slidingly fit with the two guide grooves 302 , the lock body 3 is also equipped with a secondary lock 4 , and the corresponding connector socket shell 1 is provided with a positioning component 5 that is positioned and matched with the secondary lock 4 .

[0047] In this technical solution, the lock body 3 and the connector plug shell 2 are rotated and matched. When the connector socket shell 1 and the connector plug shell 2 need to be locked and positioned after being matched, the lock body 3 is first rotated relative...

[0056] The second embodiment: as Figure 11 to Figure 13 As shown, the structure is basically the same as that of the first embodiment, the difference is that the bottom of the insertion groove 304 between the positioning through groove 305 and the secondary positioning through groove 306 is provided with a guide groove 309, corresponding to the front thrust protrusion The platform 401-1 is extended with a guide block 401-3 that guides and cooperates with the guide groove 309, and its combination principle and positioning principle are the same as those of the first embodiment, which will not be repeated here.

[0057] In this embodiment, the ejection column on the connector socket shell 1 in the first embodiment is canceled, and two limit holes 501-1 are reserved, as shown in Figure 13 As shown, the function of the first embodiment can also be realized, that is, by pushing the secondary lock 3, the guide block 401-3 slides forward along the guide groove 309 until the guide b...

[0058] The third embodiment: as Figure 14 to Figure 15 As shown, the structure is basically the same as that of the first and second embodiments. The difference is that a positioning boss 202 is provided on the connector plug housing 2 below the fixing column 201, and a positioning boss 202 is provided on the lock body 3 below the corresponding positioning hole 301. The second positioning hole 310 that cooperates with the positioning boss 202; the main function is to prevent the secondary lock 3 from rotating arbitrarily due to no positioning before the assembly of the connector socket shell 1 and the connector plug shell 2, so as to prevent the secondary lock from being rotated arbitrarily. 3 is positioned on the connector plug housing 2.

[0059] The positions of the positioning boss 202 and the second positioning hole 310 can be interchanged.

[0060] Also, the solution of this embodiment can be applied to either the first embodiment or the second embodiment.

Abstract

The invention relates to the field of the connector, particularly to a secondary locker support system for a connector. The system is composed of a connector socket housing and a connector plug housing that cooperate with each other. Two fixed posts are arranged at the two sides of the connector plug housing; and a main locking body and the two fixed posts are in a running fit relationship by two positioning holes formed at the two sides. Besides, two guiding slots are formed in the two sides of the main locking body; two guiding posts in a sliding fit relationship with the two guiding slots are arranged at the two sides of the connector socket housing correspondingly. And a secondary locker is installed at the main locking body; and a positioning assembly in a positioning fit relationship with the secondary locker is arranged at the connector socket housing correspondingly. The system has advantages of simple structure, convenient installation, high production efficiency, good secondary mechanical anti-loosening effect, and high stability and firmness.

Description

technical field [0001] The embodiment of the present invention relates to the field of connectors, in particular to a secondary locking device guarantee system for connectors. Background technique [0002] The connector position assurance system (connector position assurance-CPA) is a very important security system in the connector. For the application trend of locks, there are high requirements for their performance, locking performance, strength requirements and comfort of use. At the same time, try to make the product structure simple, easy to operate and practical. [0003] But in prior art, there is following defect: [0004] 1) There is no secondary locking function in the structure, and the user cannot be clearly reminded whether the lock is assembled in place, that is, even if the lock is not fully locked in place, the connector can still be used; and the buckle of this structure is in use. It is easy to slip due to the harsh environment of use (such as vibration,...
