The connecting piece comprises a plurality of connecting hooks 10 and a single contact body 20, wherein the connecting hooks 10 are distributed on the contact body 20 at intervals, and the dismounting connecting structure of two batteries is realized through the connecting hooks; current conduction between the two cells is achieved by the contact 20.

The connection hook 10 comprises a hook body 101 and a limiting body 102, the hook body 101 is connected with the contact body 20, the limiting body 102 is arranged on the hook body 101, the limiting body 102 is positioned on one side of the hook body 101 facing the contact body 20, a clamping part 103 is formed between the limiting body 102 and one end part of the hook body 101, a connecting part of another battery is clamped into the clamping part 103, position limitation is achieved through the limiting body 102, namely, the connecting part of the other battery cannot be clamped continuously after being contacted with the limiting body 102. In a specific application, the hook body 101 has a connection end 1011 and a clamping end 1012, the connection end 1011 is connected with the contact body 20, the clamping end 1012 is bent towards the direction approaching the contact body 20, and a clamping part 103 is formed between the clamping end 1012 and the limiting body 102. Specifically, the number of the connection hooks 10 is four, and the four connection hooks 10 are symmetrically distributed on the contact body 20 in pairs at intervals; the hook body 101 is made of high yield strength material, and when the connecting part of another battery is clamped in or pulled out, the hook body 101 deforms, so that the installation and the disassembly are realized.

The contact body 20 includes a carrying plate 201 and a plurality of main contact claws 202, the connecting end 1011 of the hook body 101 is connected with the carrying plate 201, and the limiting body 102 is located at one side of the hook body 101 facing the carrying plate 201. The carrier 201 has a contact surface 2011 and a fixing surface 2012, wherein the contact surface 2011 specifically refers to a surface facing a product to be connected, and the fixing surface 2012 is a surface for fixing the whole carrier 201. One end of the plurality of main claws 202 is disposed on the contact surface 2011, and the other end of the main claw 202 extends in a direction away from the contact surface 2011, that is, the main claw 202 protrudes from the contact surface 2011.

Further, the carrier 201 further has a carrier hole 2013, and the plurality of main contact fingers 202 are distributed on a wall surface of the carrier hole 2013 at intervals. Specifically, the bearing hole 2013 is located at a middle position of the bearing plate 201, and of course, the bearing hole 2013 may be formed at other positions, not limited to the middle position.

Furthermore, a plurality of slots 2014 are further formed at the edge of the carrier 201, and a hook 101 is disposed in each slot 2014, i.e. the number of the slots 2014, the hook 101 and the limiting body 102 is the same.

In this embodiment, the cross section of the carrier plate 201 is circular so as to better fit with the end of the battery, and of course, the shape thereof may be rectangular or the like, and is not particularly limited. The carrier plate 201 is made of a highly conductive material, such as aluminum, copper, etc., to facilitate current conduction.

Preferably, the cross section of the connection between the first contact section 2021 and the second contact section 2022 is in an arc structure, and since the connection between the first contact section 2021 and the second contact section 2022 is the first place to make contact, the arc structure is beneficial to increasing the contact area 2011, and in addition, the pole piece end of the battery is not easy to be damaged or pierced. In a specific application, the main contact claw 202 is made of a material with high conductivity and high yield strength, so that not only can conductivity be realized, but also deformation can be realized under the action of force, and better forward force can be generated after deformation so as to reduce the resistance value existing in the electric connection.

The contact body 20 further includes a plurality of secondary contact claws 203, the plurality of secondary contact claws 203 are also disposed on the wall surface of the bearing hole 2013, and the plurality of secondary contact claws 203 and the plurality of primary contact claws 202 are disposed in a staggered manner, i.e. one secondary contact claw 203 is disposed between two primary contact claws 202, and similarly, one primary contact claw 202 is disposed between two secondary contact claws 203. The structure of the secondary contact claw 203 is the same as that of the primary contact claw 202, that is, one end of the secondary contact claw 203 is connected with the wall surface of the bearing hole 2013, and the other end extends in a direction away from the contact surface 2011, and the secondary contact claw 203 is also provided with an arc structure. In this embodiment, since the first contact section 2021 extends in a direction away from the contact surface 2011, a first included angle 2023 exists between the first contact section 2021 and the contact surface 2011, and similarly, a second included angle 2031 exists between the secondary contact claw 203 and the contact surface 2011, wherein an angle of the second included angle 2031 is larger than the first included angle 2023, and it is further required to indicate that a distance that the secondary contact claw 203 extends is smaller than a length of the first contact section 2021, and when the primary contact claw 202 is forced to deform in a direction towards the contact surface 2011, the secondary contact claw 203 contacts with the battery again, so as to further increase a contact with the battery; in addition, since the main contact claw 202 is manufactured by the stamping process in the actual production process, the secondary contact claw 203 is to reuse the material which should be used as the waste material, so as to avoid the waste of the material.

In summary, the hook 101 and the limiting body 102 form the clamping part 103, which is beneficial to the two batteries to form a quick-disassembly structure, and the clamping part 103 also plays a role in limiting, so that the installation and disassembly efficiency is greatly improved, and the working efficiency is further improved; in addition, through the arrangement of the plurality of main contact claws 202, each main contact claw 202 is a contact point, so that the number of the contact points is greatly increased, more paths are added for the conduction of current, and finally the conduction of large current is ensured, so that the requirement of actual use is met.
