Figure 7 ​Figure 2 is a schematic view of a part of the second connecting sheet 20. The portable conductive connecting structure comprises the first connecting sheet 10 and the second connecting sheet 20, and the first connecting sheet 10 and the second connecting sheet 20 are detachably connected. The first connecting sheet 10 is connected with the positive pole or the negative pole of one battery, and the second connecting sheet 20 is connected with the negative pole or the positive pole of another battery. The two batteries can be spliced through the first connecting sheet 10 and the second connecting sheet 20. The splicing or detaching of multiple batteries can be quickly completed.

[0043] The first connecting sheet 10 comprises a connecting plate 101 and a plurality of first buckles 102. The connecting plate 101 has a first contact surface 1011 and a first fixed surface 1012. The first contact surface 1011 is arranged opposite to the second connecting sheet 20. The first fixed surface 1012 is a surface of the connecting plate 101 away from the first contact surface 1011. The first fixed surface 1012 is connected with the positive pole end or the negative pole end of the battery. The plurality of first buckles 102 are distributed at the outer edge of the connecting plate 101. In specific applications, one end of the first buckle 102 is connected to the edge of the connecting plate 101, and the other end of the first buckle 102 extends away from the connecting plate 101. The first buckle 102 and the first contact surface 1011 form a first connecting angle 103, which can be a right angle, an obtuse angle or a straight angle. In this embodiment, the first connecting angle 103 is an obtuse angle. Further, the first connecting sheet 10 further comprises a plurality of clamping blocks 104, which are distributed on the first fixed surface 1012 of the connecting plate 101. One end of the clamping block 104 is connected with the connecting plate 101, and the other end of the clamping block 104 extends away from the first fixed surface 1012. The clamping block 104 is beneficial to the connection of the first connecting sheet 10 and the positive pole end of the battery. Specifically, the entire first connecting sheet 10 is made of high-conductivity material to facilitate current conduction.

[0044] The second connecting sheet 20 comprises a bearing plate 201, a plurality of main contact claws 202 and a plurality of second buckles 204. The bearing plate 201 has a second contact surface 2011 and a second fixing surface 2012. The second contact surface 2011 is arranged opposite to the first contact surface 1011. The second fixing surface 2012 is a surface of the bearing plate 201 away from the second contact surface 2011. The second fixing surface 2012 is connected with the negative electrode end of the battery to realize fixing. One end of the plurality of main contact claws 202 is arranged on the second contact surface 2011. The other end of the main contact claw 202 extends away from the second contact surface 2011, that is, the main contact claw 202 is arranged in a protruding manner on the second contact surface 2011. The plurality of main contact claws 202 abut against the first contact surface 1011. The plurality of second buckles 204 are distributed at intervals on the outer edge of the bearing plate 201. The second buckle 204 is matched with the first buckle 102 and is detachably connected. That is, the connection of the first buckle 102 and the second buckle 204 can realize the connection of the two batteries. The second connection angle 205 exists between the second buckle 204 and the second contact surface 2011. The second connection angle 205 can be a right angle or an obtuse angle. In the embodiment, the second connection angle 205 is a right angle, that is, the second buckle 204 is arranged perpendicular to the second contact surface 2011.

[0045] Further, the bearing plate 201 also has a bearing hole 2013. The plurality of main contact claws 202 are distributed at intervals on the wall surface of the bearing hole 2013. Specifically, the bearing hole 2013 is located at the middle position of the bearing plate 201. Of course, the bearing hole 2013 can also be arranged at other positions and is not limited to the middle position. In the embodiment, the bearing plate 201 is made of a high-conductivity material, such as aluminum, copper, etc., which is convenient for conducting current.

[0046] The main contact claw 202 comprises a first contact section 2021 and a second contact section 2022. One end of the first contact section 2021 is connected with the wall surface of the bearing hole 2013. The other end of the first contact section 2021 extends away from the second contact surface 2011. At the same time, the other end of the first contact section 2021 is connected with one end of the second contact section 2022. The other end of the second contact section 2022 extends towards the second contact surface 2011. Preferably, the cross section of the connection between the first contact section 2021 and the second contact section 2022 is in an arc structure. Since the connection between the first contact section 2021 and the second contact section 2022 is the first contact position, arranging the connection in an arc structure is beneficial to increase the contact area and is not easy to cause damage to the first contact surface 1011. In specific applications, the main contact claw 202 is made of a high-conductivity and high-yield strength material, which can not only conduct electricity but also deform under the action of force. After deformation, a better normal force can be generated to reduce the resistance value existing in the electrical connection.

[0047] The second connecting sheet 20 further comprises a plurality of secondary contact claws 203, which are arranged on the wall of the bearing hole 2013 and staggered with the primary contact claws 202, i.e. one secondary contact claw 203 is arranged between two primary contact claws 202, and one primary contact claw 202 is arranged between two secondary contact claws 203. The secondary contact claws 203 have the same structure as the primary contact claws 202, i.e. one end of the secondary contact claw 203 is connected with the wall of the bearing hole 2013, and the other end extends away from the second contact surface 2011, and the secondary contact claw 203 also has an arc structure. When a sufficient force is applied to the battery, the primary contact claws 202 and the secondary contact claws 203 are all in abutment with the first contact surface 1011. In this embodiment, since the first contact section 2021 extends away from the second contact surface 2011, a first included angle 2023 is formed between the first contact section 2021 and the second contact surface 2011, and a second included angle 2031 is formed between the secondary contact claw 203 and the second contact surface 2011, wherein the second included angle 2031 is larger than the first included angle 2023. It should be noted that the extension distance of the secondary contact claw 203 is smaller than the length of the first contact section 2021. When the primary contact claws 202 are deformed in the direction of the second contact surface 2011 under the force, the secondary contact claws 203 are in contact with the battery, thereby further increasing the contact points with the battery. In addition, since the primary contact claws 202 are made by stamping process in the actual production process, the secondary contact claws 203 are made by reusing the material that should be waste, thereby avoiding the waste of materials.

[0048] By arranging the plurality of primary contact claws 202, each primary contact claw 202 is a contact point, thereby greatly increasing the number of contact points, and more paths for the conduction of current are provided, thereby ensuring the conduction of large current to meet the actual use requirements.

[0049] The second buckle 204 has a buckle opening 2041, when the first buckle 102 is connected with the second buckle 204, the end of the first buckle 102 away from the connecting plate 101 is located in the buckle opening 2041, thereby realizing the connection of the two batteries. Further, the end of the first buckle 102 away from the connecting plate 101 has an arc surface 1021, the end of the second buckle 204 away from the bearing plate 201 has an inclined surface 2042, and the inclined surface 2042 extends to the buckle opening, through the cooperation of the arc surface 1021 and the inclined surface 2042, the connection of the first buckle 102 and the second buckle 204 is more conducive, and the effect of guiding and smooth transition is achieved. It should be noted that in the embodiment, the end of the second buckle 204 away from the bearing plate 201 is bent towards the second contact surface 2011, thereby forming the buckle opening 2041. Specifically, the second buckle 204 is made of a material with high yield strength, when the first buckle 102 moves along the inclined surface 2042 towards the buckle opening 2041, the second buckle 204 will be outwardly expanded under the action force applied by the first buckle 102, after the first buckle 102 falls into the buckle opening 2041, the second buckle 204 is reset. Since the second buckle 204 has a deformable characteristic, when disassembling is needed, only a sufficient force needs to be applied to the first connecting piece 10 to make the first buckle 102 separate from the buckle opening 2041.

[0051] As shown in Figures 7-11 , Figure 8 is another use scene diagram of the portable conductive connection structure; Figure 9 is Figure 8 a B part enlarged view in the figure; Figure 10 is another split state diagram of the portable conductive connection structure; Figure 11 is another sectional view of the second connecting piece 20. The structure of the embodiment is basically the same as that in the embodiment one, the difference is that the first connecting piece 10 in the embodiment is not provided with the clamping block 104, but is directly connected with the positive electrode end of the battery through the first fixed surface 1012, specifically, the first fixed surface 1012 is connected to the positive electrode end surface of the battery by welding. In addition, the first connecting angle 103 between the connecting plate 101 and the first buckle 102 in the embodiment is a flat angle. At the same time, the first angle 2023 and the second angle 2031 of the main contact claw 202 and the secondary contact claw 203 relative to the second contact surface 2011 are adjusted in the embodiment, so that the main contact claw 202 and the secondary contact claw 203 in the embodiment are more flat.

[0052] Embodiment three

[0053] As shown in Figure 7 , Figures 12-17 , Figure 12 is another use scene diagram of the portable conductive connection structure; Figure 13 isFigure 12 C part in the enlarged view in; Figure 14 Is another split state diagram of portable conductive connection structure; Figure 15 Is another three-dimensional structure schematic diagram of the first connecting piece 10; Figure 16 Is another sectional view of the first connecting piece 10; Figure 17 Is another sectional view of the second connecting piece 20. The structure of the embodiment is similar to that of the first embodiment, and the difference lies in that the first connecting piece 10 further comprises a plurality of contact blocks 105 in the embodiment. One end of the contact block 105 is connected with the first contact surface 1011, and the other end of the contact block 105 is abutted with the second contact surface 2011. Through the arrangement of the contact block 105, the contact points between the first connecting piece 10 and the second connecting piece 20 are further increased. At the same time, the contact block 105 also plays a limiting role, avoiding the application of excessive force to the first connecting piece 10, which may cause damage due to the direct contact between the first contact surface 1011 and the second contact surface 2011. Specifically, the stamping process is used to stamp from the first fixed surface 1012 to the first contact surface 1011, thereby forming the contact block 105.

[0054] In addition, the second connecting angle 205 between the second buckle 204 and the second contact surface 2011 is an obtuse angle in the embodiment, so that there is a spacing between the second buckle 204 and the negative electrode end of the battery. During the process of clamping the first buckle 102 into the buckle opening 2041, the spacing provides space for the outward expansion of the second buckle 204. Furthermore, the two second buckles 204 are connected as a group in the embodiment, thereby enhancing the stress strength of the second buckle 204 and being beneficial to prolong the service life of the second buckle 204.

[0055] As described above, the first connecting piece 10 and the second connecting piece 20 are connected with the positive and negative electrodes of the battery respectively. When the first buckle 102 and the second buckle 204 are connected, the main contact claw 202 is in contact with the first contact surface 1011 to realize current conduction, thereby ensuring the normal use of the battery after connection. The connection of the first buckle 102 and the second buckle 204 can realize quick installation or disassembly, thereby greatly improving the convenience and efficiency of operation.

[0056] The above only describes the embodiments of the present application and is not used to limit the present application. The present application can have various changes and variations for those skilled in the art. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the scope of the claims of the present application.
