[0019] The following combines the drawings and embodiments to further describe in detail the specific embodiments of the utility model. The following embodiments or drawings are used to illustrate the utility model, but not to limit the scope of the utility model.

[0020] Embodiment 1:

[0021] A vertically locking type automotive battery joint, as Figures 1 to 3 shown, includes a joint body 1, a flat washer 2, a wedge locking block 3, a bolt 4, and a nut 5. The head of the joint body 1 is connected to the battery pole column, and the tail of the joint body 1 is connected to a wire. Parallel first fastening piece 6 and second fastening piece 7 are provided at the side opening of the head of the joint body 1. The bolt 4 passes through the first fastening piece 6 and the second fastening piece 7, and the head of the bolt 4 abuts against the outer end of the first fastening piece 6. The flat washer 2 and the wedge locking block 3 are both installed in the middle of the bolt 4, and the flat washer 2 is clamped between the wedge locking block 3 and the second fastening piece 7. The end face of the flat washer 2 adjacent to the wedge locking block 3 is a plane, and a partial area of the end face of the wedge locking block 3 adjacent to the flat washer 2 abuts against the flat washer 2. The nut 5 is installed at the tail of the bolt 4 and abuts against the wedge locking block 3.

[0022] By adjusting the distance between the first fastening piece 6 and the second fastening piece 7 through the cooperation of the flat gasket 2, the wedge locking block 3, the bolt 4, and the nut 5, the head of the joint body 1 is reduced, and the purpose of firmly clamping the head of the joint body 1 on the battery terminal post is achieved. This installation method reduces the requirement for installation space. The wedge locking block 3 abuts against the flat gasket 2 in a partial area contact manner, replacing the traditional planar contact, which can effectively reduce the resistance during the assembly and locking process.

[0023] The first fastening piece 6 and the second fastening piece 7 are inclined along the central axis of the head of the joint body 1, and the bolt 4 is a bent bolt.

[0024] The bent bolt 4 can provide additional anti-torsion ability and stability, and the angle settings of the wedge locking block 3, the nut 5, the first fastening piece 6, and the second fastening piece 7 can still ensure that the joint body 1 has the advantage of low requirement for installation operation space.

[0025] A first limiting piece 10 that abuts against the head of the bolt 4 is provided on the side of the first fastening piece 6, a second limiting piece 11 that abuts against the side of the flat gasket 2 is provided on the side of the second fastening piece 7, and two third limiting pieces 12 that abut against the side of the wedge locking block 3 are provided on the flat gasket 2. One of the third limiting pieces 12 is located on the side of the wedge locking block 3 close to the joint body 1, and the other third limiting piece 12 is located on the other side of the wedge locking block 3. The third limiting piece 12 can limit the offset phenomenon of the wedge locking block 3 and prevent the wedge locking block 3 from directly contacting the joint body 1.

[0026] Embodiment 2:

[0027] As Figure 4 shown, the end face of the wedge locking block 3 adjacent to the flat gasket 2 is an arc end face 8, and the top of the arc end face 8 abuts against the flat gasket 2. The convex surface design is adopted to replace the traditional planar contact method, reducing the resistance during the assembly and locking process.

[0028] Embodiment 3:

[0029] As Figure 5 shown, at least one convex block 9 is provided on the end face of the wedge locking block 3 adjacent to the flat gasket 2, and the top of the convex block 9 abuts against the flat gasket 2. The convex surface design is adopted to replace the traditional planar contact method, reducing the resistance during the assembly and locking process.

[0030] The above is only a preferred embodiment of the present invention, and does not impose any form of limitation on the present invention. Any simple modification or equivalent change made to the above embodiments based on the technical essence of the present invention falls within the protection scope of the present invention.
