[0032] The following further elaborates on the embodiments of the present application with reference to the drawings:

[0033] The present application provides a wire branch connector, which includes a first connecting plate 100 and a second connecting plate 200. The second connecting plate 200 is used to be disposed opposite to the first connecting plate 100 to form at least two wire channels 300 with different extending directions between the first connecting plate 100 and the second connecting plate 200. The wire channels 300 are used to install the wires to be connected, and both ends of each wire channel 300 penetrate through the side of the connector body 400 formed by the first connecting plate 100 and the second connecting plate 200. Both the first connecting plate 100 and the second connecting plate 200 are conductors.

[0034] Optionally, all of the wire channels 300 are formed by the cooperation of the first wire grooves 120 opened on the first connecting plate 100 and the second wire grooves 220 opened on the second connecting plate 200. Refer to Figure 2 the main wire channel 310 in

[0035] Optionally, a part of the wire channel 300 is formed by the cooperation of the first wire groove 120 formed in the first connecting plate 100 and the second wire groove 220 formed in the second connecting plate 200, referring to the branch channel 320 in Figures 1-4 .

[0036] Optionally, the wire channel 300 is configured as follows: all the channel segments of the wire channel 300 are solely constituted by the first wire groove 120 formed in the first connecting plate 100, or are formed by the cooperation of the first wire groove 120 in the first connecting plate 100 and the surface of the second connecting plate 200.

[0037] Optionally, the wire channel 300 is configured as follows: some of the channel segments of the wire channel 300 are solely constituted by the first wire groove 120 formed in the first connecting plate 100 (such as the intersecting channel segment 321 of the branch channel 320 in Figure 4 ), or are formed by the cooperation of the first wire groove 120 formed in the first connecting plate 100 and the surface of the second connecting plate 200.

[0038] In the above implementation process, since both ends of each wire channel 300 formed by the cooperation of the first connecting plate 100 and the second connecting plate 200 penetrate through the side of the connector body 400 formed by the first connecting plate 100 and the second connecting plate 200, when using the above wire branch connector to electrically connect wires, the wires to be connected can be arranged along a predetermined direction at the position of the first connecting plate 100 corresponding to the wire channel 300 (such as the first wire groove 120 on the first connecting plate 100), and then the second connecting plate 200 is buckled on the second connecting plate 200, the wires are buckled between the first connecting plate 100 and the second connecting plate 200, and then the first connecting plate 100, the second connecting plate 200 and the wires are firmly connected by using a locking member 500 or crimping, thereby realizing electrical connection and structural connection.

[0039] When using the locking member 500 to fasten the first connecting plate 100 and the second connecting plate 200, the following structure can be adopted: at least one first connection hole 110 is formed in the first connecting plate 100, at least one second connection hole 210 is formed in the second connecting plate 200, the locking member 500 extends into the first connection hole 110 and the second connection hole 210, and is detachably connected to the first connection hole 110 and the second connection hole 210, and the cross-sectional area of all or part of the channel segments of each wire channel 300 is smaller than the cross-sectional area of the wire to be connected.

[0040] Optionally, the locking member 500 can be a rivet or a bolt. When the locking member 500 is a bolt, internal threads for mating with the bolt start to be formed on the inner surfaces of the first connection hole 110 and the second connection hole 210. Preferably, the bolt includes a nut and a screw rod, and a necking is provided at the connection between the nut and the screw rod. After the bolt tightens the first connecting plate 100 and the second connecting plate 200, it can break at the necking, that is, the nut breaks away from the screw rod, which can reduce the overall volume after the wire branch connector is connected.

[0041] Preferably, the number of the first connection holes 110 and the second connection holes 210 is more than two. The more than two first connection holes 110 and second connection holes 210 are distributed on both axial sides of all the wire channels 300, so as to fasten all the wires to be connected from both of their axial sides, which can improve the stability of the electrical connection and the structural connection of the wires to be connected.

[0042] In a possible implementation manner, any two wire channels 300 are arranged in an offset manner up and down at the intersection.

[0043] In the above implementation process, if a part where two wire channels 300 intersect is formed on the first connecting plate 100 or the second connecting plate 200, arranging the two wire channels 300 in an offset manner up and down at the intersection can increase the accommodation space at the intersection. Since the wires to be connected include a metal material and have a certain hardness, increasing the accommodation space at the intersection facilitates the buckling together of the first connecting plate 100 and the second connecting plate 200, and then fastening is performed in the form of crimping or using the locking member 500.

[0044] In a possible implementation manner, at least two wire channels 300 include a main wire channel 310 and at least one branch wire channel 320. The cross-sectional area of the main wire channel 310 is larger than that of the branch wire channel 320. The branch wire channel 320 includes an intersecting channel section 321 and at least one extending channel section 322. The intersecting channel section 321 is formed on the inner surface of the main wire channel 310 section. One end of the extending channel section 322 is communicated with the intersecting channel section 321, and the other end penetrates through the side of the connector body 400 formed by the opposite setting of the first connecting plate 100 and the second connecting plate 200.

[0045] Optionally, the branch wire channel 320 includes two extending channel sections 322, and the two extending channel sections 322 are respectively communicated with both ends of the intersecting channel section 321.

[0046] In a possible implementation manner, there are two branch wire channels 320, and the parts where the two branch wire channels 320 intersect with the main wire channel 310 are respectively formed on the first connecting plate 100 and the second connecting plate 200.

[0047] In a possible implementation, the included angle between the branch channel 320 and the main channel 310 is α, where 5° ≤ α < 90°. Optionally, the included angle α between the branch channel 320 and the main channel 310 is 5°, 10°, 30°, 40°, 45°, 60°, etc.

[0048] In a possible implementation, the first connecting plate 100 includes a first arc portion 130 and first straight portions 140 connected to both axial sides of the first arc portion 130. The cross-section of the first arc portion 130 is arc-shaped, and a first main groove 150 is formed on the first arc portion 130. The first main groove 150 cooperates with the second connecting plate 200 to form the main channel 310. At least one first through hole for connecting the locking member 500 is formed on each first straight portion 140.

[0049] The second connecting plate 200 includes a second arc portion 230 and second straight portions 240 connected to both sides of the second arc portion 230. The cross-section of the second arc portion 230 is arc-shaped, and a second main groove 250 is formed on the second arc portion 230. The second main groove 250 cooperates with the surface of the first connecting plate 100 or the first main groove 150 on the first connecting plate 100 to form the main channel 310. At least one second through hole for the locking member 500 is formed on each second straight portion 240.

[0050] The locking member 500 extends into the first through hole and the second through hole and is connected to the first through hole and the second through hole, thereby locking the first connecting plate 100 and the second connecting plate 200.

[0051] Preferably, the thickness of the first straight portion 140 of the first connecting plate 100 is equal to or slightly equal to the thickness of the first arc portion 130.

[0052] Preferably, the cross-sectional area of part or all of the channel segments of the wire channel 300 is 60% - 99% of the cross-sectional area of the wire to be connected, so as to ensure that the first connecting plate 100 and the second connecting plate 200 firmly connect the wire to be connected.

[0053] Preferably, the first connecting plate 100 and the second connecting plate 200 have the same structure, so that any two connecting plates can be combined with each other to form a wire branch connector to connect the wire.

[0054] In a possible implementation, a plurality of grooves are formed on the surface of the wire channel 300, and a toothed strip is formed between adjacent two.

[0055] During the above implementation process, the toothed strips formed by opening grooves on the surface of the wire channel 300 can increase the friction between the wire channel 300 and the wire, effectively improving the stability of the structural connection between the wire channel 300 and the wire. Moreover, during the crimping or locking process, the toothed strips will pierce the oxide layer on the surface of the wire, and at the same time, the oxide layer on the surface of the toothed strips will also be damaged. Therefore, the electrical connection performance between the wire channel 300 and the wire can be improved.

For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and without departing from the spirit or basic features of the present application, the present application can be implemented in other specific forms.
