Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The embodiment of the power battery connector assembly of the utility model, as shown in fig. 1 to fig. 3, the power battery connector assembly comprises a plug 2 and a socket 1, the plug 2 comprises a plug housing 21 extending along the front and back direction, the socket 1 comprises a socket housing 11, a locking groove 15 is arranged on the periphery of the socket housing 11, a locking rod 23 with a front end overhanging forwards is hinged on the front end of the plug housing 21, a locking bulge 231 protruding downwards and used for being locked in the locking groove 15 is arranged at the front end of the locking rod 23, a locking bulge 232 protruding outwards is arranged on the outer side of the locking rod 23, a locking cap 22 with a locking position and an unlocking position is assembled on the plug housing 21 along the front and back direction guiding movement, when the locking cap 22 is in the locking position, the inner wall of the locking cap 22 is radially pressed and matched with the locking protrusion 232, and the locking cap 22 has an unlocking space 221 which is used for avoiding the locking protrusion 232 when the locking cap 22 is in the unlocking position so that the front end of the locking rod 23 can rotate outwards.

The socket housing 11 is provided with a socket insulator 13, and the socket insulator 13 is inserted into the socket housing and then press-fitted and fixed in the socket housing by a socket insulator stopper 12. The socket contact 14 is a pin contact, and is fixed in the socket insulator. The plug shell is provided with a plug insulator 26, and the plug contact 25 is a pin contact and is fixedly installed in the plug insulator 26.

In order to keep the locking cap 22 in the locking position at all times, in the present embodiment, a locking spring 24 for providing an elastic force to the locking cap 22 to keep it in the locking position is provided between the locking cap 22 and the plug housing 21. The locking cap 22 is always in the locking position due to the elastic force of the locking spring 24, and when the locking cap 22 needs to be moved backward to be compressed against the elastic force of the locking spring 24.

In the present example, the locking spring 24 is embodied as a cylindrical helical spring which is fitted over the plug housing 21. The use of a cylindrical helical spring on the one hand provides a sufficiently large spring force and on the other hand allows a sufficiently large stroke of the locking cap 22, so that the locking lever 23 can be well avoided. The specific installation structure of the locking spring is shown in fig. 2, a plug housing stop 211 is arranged on the plug housing, a locking cap stop 222 is arranged on the inner wall of the locking cap, and the locking spring is installed between the two stops. In order to prevent the locking cap from coming off, a stopper plate 27 capable of stopping with the plug housing abutment to prevent the locking cap from coming off is installed at the rear end thereof.

In the present embodiment, the fastening protrusion 231 is embodied as an arc protrusion structure. Therefore, in the unlocking process, the front end of the locking rod 23 can be driven to swing upwards by the cooperation of the arc-shaped convex structures and the locking groove 15, so that unlocking can be smoothly completed.

Considering that the unlocking space 221 needs to be provided in the rear of the middle of the locking cap 22 if the locking protrusion 232 is provided in the middle or rear position of the locking lever 23, which makes the locking cap 22 difficult to process, in the present embodiment, the locking protrusion 232 is provided radially opposite to the catching protrusion 231, that is, the locking protrusion 232 is provided in the front position of the locking lever, which enables the unlocking space 221 to be provided in the front position of the locking cap. This has another object that the pressing force applied from the locking cap can be directly transmitted to the catching protrusion 231, thereby increasing the locking force. Here, the locking cap is provided to the front end of the plug so as to cover the front end at the joint position of the plug housing 21 and the socket housing 11, and plays a role of protection.

In the present embodiment, the locking lever is a straight lever structure extending in the front-rear direction, and a connecting portion extending downward and used for being hinged with the plug housing 21 is provided at the rear end of the locking lever. With this structure, the straight rod portion is attached to the socket housing 11 after the locking lever is locked.

In this example, the plug and the socket are rectangular connectors, locking grooves 15 are provided on opposite sides of the socket housing 11, and locking bars are provided corresponding to the locking grooves 15. Therefore, the locking force is relatively uniform, and the stability during locking is improved.

The utility model discloses a during power battery connector subassembly uses, dock plug and socket each other, after pegging graft and targetting in place, the protruding lock of lock on the check lock lever on the plug casing is in the locking groove, make plug casing and socket can interconnect, locking cap is in locking position simultaneously, its inner wall passes through the locking arch and exerts the locking force to the check lock lever, make the protruding position that lies in the locking groove lock of keeping of lock on the check lock lever, prevent the unblock, when needs unblock, remove locking cap unblock position, unblock space on the locking cap dodges and opens locking arch this moment, make the check lock lever can outwards remove, thereby make the protruding and locking groove of lock break away from the cooperation, realize the unblock, in this kind of connector, locking structure no longer produces deformation, avoid the problem of the locking inefficacy that its fatigue fracture caused.

In other embodiments of the present invention, the locking spring may also be a ripple spring; the buckling bulge can also be a boss structure with an inclined plane; the number of the locking rods can be specifically set according to the requirement; the locking protrusion may be further provided at a middle position of the locking lever.

The above description is only a preferred embodiment of the present invention, and should not be taken as limiting the invention, and any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
