Detailed Description

The present invention will be described in further detail with reference to the following embodiments, which are illustrative, not restrictive, and the scope of the invention should not be limited thereto.

A novel automobile connector locking structure is characterized in that a female end connector body 41 is in nested fit with a male end connector body 43, the female end connector body is inserted into a slot in the upper portion of the male end connector body for limiting and fixing, and a male end TPA 44 is mounted on a terminal in the lower portion of the male end connector body; female end TPA 42 is installed on the terminal of female end connector body upper end one side, open type spacing groove 45 of upper and lower slide is made to female end connector body upper end opposite side system, locking structure (1-1) of this open type spacing inslot embedding installation, and this locking structure lower extreme system has one-way colludes, has one and one-way colludes the complex square hole on male end connector body upper portion system, and the one-way position that can lock female end connector body and male end connector body in colluding the card income square hole.

In order to prevent the locking structure from deforming and disengaging, a CPA protection sheet 46 is inserted into the opening type limiting groove in a tightly-adhered locking structure, the CPA protection sheet comprises an upper end pressing cap, an elastic insertion sheet and an arc insertion sheet, the upper end pressing cap is provided with a bent plate structure with an arc break angle, the lower end of the upper end pressing cap is provided with the elastic insertion sheet and the arc insertion sheet at intervals in parallel, two sides of the middle part of the elastic insertion sheet are provided with bulges, the middle part of the elastic insertion sheet is provided with a plurality of through grooves, the elastic insertion sheet is embedded into a slot formed in the middle part of the upper end of the locking; the arc inserted sheet inserts between locking structure and the open type spacing inslot wall.

Instructions for use:

① the TPA (42) and CPA (46) are pre-loaded into the corresponding positions of the new female connector body (45) at the factory, and the shipment status is as shown in figure 3.

② the female end connector body (45) of the assembled wiring harness is installed on the male end connector body (43) of the assembled wiring harness, after the bolt is in place, the CPA (46) is pressed into the locking position to complete the assembly, and the state after the assembly is completed refers to figure 4.

③, the CPA (46) is pushed to the pre-load position to depress the CPA (46) to unlock the connector.

Due to the fact that the CPA (46) is added, even if the locking structure is stressed under the condition that the connector is locked, due to the action of the CPA (46), the locking structure cannot be stressed and deformed, therefore, the situation of disengagement cannot occur, and the smooth circuit connection can be guaranteed.
