Detailed Description

The present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. The embodiment is implemented on the premise of the technical solution of the present invention, and a detailed implementation manner and a specific operation process are given, but the scope of the present invention is not limited to the following embodiments.

As shown in fig. 1, an improved CPA structure comprises a connection position assurance element 1 and a connector housing 2, a connector is embedded in the connector housing 2, as shown in fig. 4, a connection position assurance element fixing groove 4 is formed in the top end of the connector housing 2, the connection position assurance element 1 comprises a connection position assurance rod 6, a free end 7 is arranged at the tail end of the connection position assurance rod 6, bosses 8 are symmetrically arranged on the outer side surfaces of two sides of the connection position assurance element 1, as shown in fig. 5, boss limiting portions 5 corresponding to the bosses 8 are symmetrically arranged on the inner side surfaces of two sides of the connection position assurance element fixing groove 4, as shown in fig. 2 and 3, the free end 7 moves forward, the bosses 8 enter the boss limiting portions 5 to limit the connection position assurance element 1.

As shown in fig. 7, the boss 8 is provided with a connection face 11 and a protruding face 10, and the connection face 11 and the connection position assurance element 1 are connected by the connection face 11, and the angle between the connection face 11 and the protruding face 10 is 90 °.

The number of bosses 8 on a single side of the connecting position assurance element 1 is 1.

As shown in fig. 6, the top of the connecting position assurance member 1 is provided with a movable base 9.

The movable base 9 is located at one end of the top of the connecting position assurance member 1 near the connecting position assurance lever 6.

The movable base 9 has a stepped structure from bottom to top.

The top end of the connector is provided with a locking claw 3 which cooperates with the free end 7.

Example one

The connecting position assurance component 1 enters the connecting position assurance component fixing groove 4 on the connector housing 2 in advance, and is in the pre-locking position of the connecting position assurance component fixing groove 4, after the connector is arranged on the fitting end, the connecting position assurance component 1 moves forward, enters the locking position of the connecting position assurance component fixing groove 4, meanwhile, the connecting position assurance rod 6 drives the free end 7 to be clamped with the locking claw 3, the boss 8 enters the boss limiting part 5 of the connecting position assurance component fixing groove 4, and therefore the connecting position assurance component 1 is limited. When the connector needs to be separated from the mating end, the movable base 9 is pressed downward, the free end tilts up and is separated from the locking claw 3, and simultaneously the boss 8 moves downward and exits from the boss stopper 5, and the connector can be separated from the mating end as the connecting position assurance member 1 moves rearward.
