The connector assembly generally includes first and second connectors that are removably connected, such as a fixed board end connector and a wire end connector that is connected to a wire harness. The second connector is plugged with the first connector to realize electric connection. Currently, as the internal space of the battery pack tends to be compact, the space left for the second connector to be assembled with the first connector in a butt joint is relatively small. When the second connector is detached from the first connector, the unlocking buckle needs to be manually operated, and then the second connector is pulled out, but the force is difficult to be exerted by hands in a narrow space, so that the second connector is difficult to pull out, and the equipment can be damaged due to the fact that the force is too strong.

Therefore, the embodiment of the application provides a connector assembly for a battery, which is convenient for an operator to take out a second connector from a slot of a first connector even in a narrow space in a battery pack by arranging an elastic structure. In addition, the embodiment of the application also provides a battery comprising the connector assembly for the battery.

FIG. 1 is a schematic illustration of a connector assembly 010 in an embodiment of the application with a second connector 200 thereof in an assembled position; FIG. 2 is a schematic diagram of a first connector 100 according to an embodiment of the application; fig. 3 is a schematic diagram of a second connector 200 according to an embodiment of the application. As shown in fig. 1 to 3, a connector assembly 010 for a battery according to an embodiment of the present application includes a first connector 100 and a second connector 200. Alternatively, the first connector 100 is fixedly mounted on a wiring board of a device (such as a battery pack) as a board-end connector, such as electrically connected to a flexible wiring board (FPC); the second connector 200 serves as a wire end connector, such as a connection with a BMS collection harness; when the second connector 200 is mated with the first connector 100, the collection harness is electrically connected to the circuit board.

In the embodiment of the present application, the first connector 100 has a slot 101, one end of the slot 101 in a first direction (arrow ab direction in the drawing) is formed as an opening, and the second connector 200 can be inserted into the slot 101 in the first direction. The second connector 200 is provided with an elastic buckle 220, and the elastic buckle 220 is used for being matched with the first connector 100 when the second connector 200 is inserted into the assembly position so as to fix the second connector 200 in the assembly position. The surface of the second connector 200 is provided with an abutting portion 210 in a protruding manner, and the side wall of the slot 101 is provided with a relief groove 102, wherein the relief groove 102 extends along the first direction. The abutment portion 210 is configured to move along the avoidance groove 102 during the process of inserting the second connector 200 into the socket 101, and an elastic structure 140 is disposed in the avoidance groove 102, where the elastic structure 140 is configured to abut against the abutment portion 210 when the second connector 200 is inserted into the assembly position, so as to provide a force for moving the second connector 200 out of the socket 101.

The second connector 200 is capable of making an electrical connection when the resilient catch 220 secures the second connector 200 in the assembled position. By providing the abutting portion 210 on the second connector 200 and providing the elastic structure 140 on the first connector 100, the second connector 200 can be subjected to a force continuously applied thereto by the elastic structure 140 in the opposite direction to the insertion direction (i.e., the b direction) when in the fitting position. When the elastic buckle 220 is in the locked state, the force exerted by the elastic structure 140 does not cause the second connector 200 to withdraw from the slot 101; when the elastic buckle 220 is unlocked, the operator does not need to pull the second connector 200 outwards by hand, and the force applied to the second connector 200 by the elastic structure 140 can enable the second connector 200 to move outwards of the slot 101, so that the second connector 200 can be automatically withdrawn. This can facilitate the operator to pull out the second connector 200 from the first connector 100, and can provide convenience for the user especially in the case where the space is small and force is not easily applied.

As shown in fig. 1 and 2, in the present embodiment, the end plate connector includes a bottom plate 110 and a shroud 120 disposed at an edge of the bottom plate 110, the bottom plate 110 and the shroud 120 together enclose a slot 101, an opening of the slot 101 is opposite to the bottom plate 110 in a first direction, and a relief groove 102 is formed inside the shroud 120.

Optionally, the spring 141 forms an angle with the first wall 103 of 60 ° to 85 °, for example, forms an angle with the first wall 103 of 80 °. By providing the elastic piece 141 so as to be inclined with respect to the first wall surface 103, the free end of the elastic piece 141 can be brought into contact with the contact portion 210 of the second connector 200 in a point contact manner. During the process of inserting the second connector 200 into the assembly position, the elastic piece 141 may be pushed by the abutting portion 210 to elastically deform, and the deformed elastic piece 141 continuously provides the second connector 200 with a force moving out of the slot 101, and the force balances with the locking force provided by the elastic buckle 220, so that the relative position between the second connector 200 and the first connector 100 is kept stable.

In alternative other embodiments, the elastic structure 140 may be other structures having elastic properties. For example, the elastic structure 140 is a spring, the second end of the avoidance groove 102 is closed, and the spring is disposed on a wall surface of the second end of the avoidance groove 102.
