[0031] As shown in Figures 1 to 3 In an embodiment, a battery connecting piece 1 for connecting with a wire includes a conductive piece 10 and a connecting piece 20. The connecting piece 20 is arranged on the conductive piece 10. The connecting piece 20 is provided with a welding groove 21 and a wire placing groove 22. The wire placing groove 22 extends from one side of the connecting piece 20 to the welding groove 21, and the wire placing groove 22 is in communication with the welding groove 21. The connecting piece 20 is provided with a clamping piece 23. One end of the wire is located in the welding groove 21 and is welded with the connecting piece 20. The end of the wire is clamped with the clamping piece 23. The end of the wire away from the clamping piece 23 extends out of the wire placing groove 22.

[0032] It needs to be explained that one end of the connecting piece 20 is arranged on one side surface of the conductive piece 10, so that the connecting piece 20 extends from the side surface of the conductive piece 10. Further, the connecting piece 20 is provided with a welding groove 21 and a wire slot 22, the welding groove 21 and the wire slot 22 are both inwardly arranged from one surface of the connecting piece 20, the wire slot 22 extends from one side surface of the connecting piece 20 to the welding groove 21, so that both ends of the wire slot 22 are respectively communicated with the welding groove 21 and one side surface of the connecting piece 20, and the diameter of the welding groove 21 is greater than the width of the wire slot 22. Further, the connecting piece 20 is provided with two clamping pieces 23, the two clamping pieces 23 are respectively located on the two sides of the welding groove 21 in the radial direction, and the included angle between the two clamping pieces 23 and the extending direction of the wire slot 22 is a right angle, so that the two clamping pieces 23 and the welding groove 21 together form a T-shaped structure. In an embodiment, the wire is a plurality of conductive metal wires twisted together, when one end of the wire is located in the welding groove 21, so that one end of the wire can be welded in the welding groove 21, and the end of the wire is clamped with one of the clamping pieces 23, and the end of the wire away from the clamping piece 23 extends from the wire slot 22. In an embodiment, one end of the wire is located in the welding groove 21, so that one end of the wire can be welded in the welding groove 21, the plurality of conductive wires are divided into two halves, and each half is twisted into an end, and the two ends are respectively clamped with the two clamping pieces 23, so that the wire forms a T-shaped structure, so that when the welding point is damaged or loose due to disbonding, the two clamping pieces 23 can continue to clamp the end of the wire, so as to avoid the risk of open circuit or poor contact of the circuit of the battery system due to the loose or disbonding of the connecting point.

[0033] As shown in Figures 2 to 3 , in an embodiment, the connecting piece 20 is also provided with a clamping groove 24, the clamping groove 24 extends from one side surface of the connecting piece 20 to the welding groove 21, and the extending direction of the clamping groove 24 and the extending direction of the wire slot 22 have an included angle, and the clamping piece 23 is located on the clamping groove 24.

[0034] It should be noted that the connecting sheet 20 is also provided with two clamping grooves 24, the two clamping grooves 24 are located on the two opposite sides of the connecting sheet 20 adjacent to the wire slot 22, and the two clamping grooves 24 extend from the side of the connecting sheet 20 into the welding groove 21 and communicate with the welding groove 21. Further, the extending direction of the two clamping grooves 24 is perpendicular to the extending direction of the wire slot 22, so that the two clamping grooves 24 and the wire slot 22 form a T shape. Further, the welding groove 21 is used for welding with one end of the wire, and since the surface of the welding groove 21 relative to the connecting sheet 20 is concave, the tin liquid can be collected in the welding groove 21 when welding, so that the tin liquid can uniformly wrap the one end of the wire, and since the welding groove 21 is located in the concave structure, more tin liquid can be collected on the wire, thereby improving the firmness of the welding point.

[0035] It should be noted that the connecting sheet 20 also includes two limiting pieces 25, and the two limiting pieces 25 are respectively located on the two opposite sides of the wire slot 22. When the end of the wire away from the clamping piece 23 is located in the wire slot 22, the two limiting pieces 25 jointly limit the wire to prevent the connection position of the wire and the welding point from being pulled by the left and right swinging force when the wire swings under external force, thereby accelerating the damage of the welding point and causing the risk of poor contact of the circuit of the battery system.

[0036] As shown in Figures 2 to 3 In an embodiment, one end of the clamping piece 23 is located on the side of the clamping groove 24 close to the wire slot 22, and the other end of the clamping piece 23 extends from one side of the clamping groove 24 to the other side.

[0037] It should be noted that one end of the two clamping pieces 23 is respectively located on the side of the two clamping grooves 24 close to the wire slot 22, and the other end of the two clamping pieces 23 respectively extends from one side of the two clamping grooves 24 to the other side, and the height of the two clamping pieces 23 is greater than the height of the connecting sheet 20, so that the two clamping pieces 23 and the connecting sheet 20 have a gap, and the two clamping grooves 24 and the welding groove 21 are in communication. In an embodiment, the end of the wire extends into the clamping groove 24 from the welding groove 21, so that the clamping piece 23 can clamp the wire. Further, since one end of the clamping piece 23 is located on the side of the clamping groove 24 on the connecting sheet 20, and the other end of the clamping piece 23 extends to the other end of the clamping groove 24, and the clamping piece 23 and the connecting sheet 20 have a height difference, so that when the end of the wire extends into the clamping groove 24, the end of the clamping piece 23 away from the wire slot 22 can be wound into the clamping groove 24, so that the clamping piece 23 clamps the end of the wire, so that the wire cannot be separated from the connecting sheet 20, thereby making the wire remain connected with the connecting sheet 20 in the case of loose or off-welding of the welding point, thereby improving the safety of the battery connection.

[0038] AsFigures 1 to 2 As shown in the figure, in an embodiment, two grooves 11 are formed on the conductive sheet 10, and the grooves 11 are respectively located at the connecting positions of the conductive sheet 10 and the connecting sheet 20, and the two grooves 11 are respectively located at the two sides of the connecting sheet 20.

[0039] It should be noted that the connecting sheet 20 extends from one side of the conductive sheet 10, and the two grooves 11 are located at the two sides of the connecting position of the connecting sheet 20 and the conductive sheet 10. Further, the included angle between the inner bottom wall and the inner side wall of the groove 11 is a rounded angle. The groove 11 is formed on the conductive sheet 10, so that the connecting position of the two sides of the connecting sheet 20 and the conductive sheet 10 is rounded. When the connecting sheet 20 swings in the transverse direction under external force, it can avoid the connecting position of the connecting sheet 20 and the conductive sheet 10 from being torn and broken.

[0040] As shown in the figure, Figure 1 , Figure 4 In an embodiment, a through hole 13 is also formed on the conductive sheet 10, and each through hole 13 is equidistantly distributed. The conductive sheet 10 is provided with a plurality of contact sheets 12, each contact sheet 12 is located in each through hole 13, and each contact sheet 12 is connected with each battery respectively.

[0041] It should be noted that the interval between each through hole 13 is greater than the diameter of the battery. Further, every two contact sheets 12 are located in one through hole 13, and the two contact sheets 12 are oppositely arranged. Further, one end of the two contact sheets 12 is arranged on the conductive sheet 10, and the other end of the two contact sheets 12 away from the conductive sheet 10 is mutually oriented, and the other end of the two contact sheets 12 mutually oriented is spaced apart, and the diameter of the contact sheet 12 is less than the diameter of the through hole 13, so that the contact sheet 12 is connected with the conductive sheet 10 at one end, and other positions are not connected with the conductive sheet 10. Further, when each through hole 13 on the conductive sheet 10 is aligned with the plurality of batteries, the two contact sheets 12 on each through hole 13 are in contact with one pole piece of the battery.

[0042] As shown in the figure, Figure 1 , Figure 4 In an embodiment, each contact sheet 12 has a height difference with the conductive sheet 10.

[0043] It should be noted that one end of the connecting sheet 20 is connected with the conductive sheet 10, and the other end of the connecting sheet 20 forms a right angle downward relative to the conductive sheet 10, so that the connecting sheet 20 can abut against the outer side wall of the battery after being connected with the wire. Further, each contact sheet 12 is protruded downward relative to the conductive sheet 10, and the protruding direction of each contact sheet 12 and the connecting sheet 20 is consistent with the direction of the right angle of the connecting sheet 20. In this way, when the contact sheet 12 contacts with the pole piece of the battery, the connecting sheet 20 can abut against the outer side wall of the battery.

[0044] The above-described embodiments only express several implementation manners of the utility model, the description is more specific and detailed, but can not therefore be understood as the limitation of the utility model patent range. It should be pointed out that for ordinary skilled person in the art, without departing from the utility model concept, several modifications and improvements can be made, which belong to the protection range of the utility model. Therefore, the protection range of the utility model patent should be subject to the appended claims.
