It should be understood that the examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes and modifications of the present invention may be made by those skilled in the art after reading the teachings of the present invention, and these equivalents also fall within the scope of the appended claims.

The technical solution of the present invention is further specifically described below by way of embodiments and with reference to the accompanying drawings.

A flexible shunt busbar is characterized in that double wire grooves 5 are formed in the top end of an outer sleeve 1, a sleeve 2 is arranged in a shell inside the outer sleeve 1, two wire grooves 5 are formed in the top of the outer sleeve 1, wires 6 are arranged in the two wire grooves 5, and the two wires 6 are not communicated. The bottom of the outer sleeve 1 is provided with a concave platform 11, the concave platform 11 is cylindrically arranged in the middle of the top of the outer sleeve 1, and a convex platform 12 with the diameter smaller than that of the concave platform 11 is arranged in the concave platform 11. The sleeve 1 sets up inside boss 12, and sleeve 2 is two, and 12 bottom junctions of boss have interface channel 21, and interface channel 21 top is cylindrical passageway, the bottom is first spigot surface 211, cylindrical passageway size adaptation in the diameter of wire 6, and the diameter of sleeve 2 is greater than the size of cylindrical passageway. Be provided with two wire posts 3 in the sleeve 2, sleeve 2 highly will be greater than

wire post

3, and 2 tops of sleeve are provided with circular opening, and this opening adaptation is in 4 sizes of copper post just, and both combine closely. By means of the structure, the whole bus bar can be in a closed state after the lead 6 is inserted into the sleeve 2 from the connecting channel 21.

Copper post 4 sets up at wire post 3 top, has the passageway 31 that runs through wire post 3 in the middle of the wire post 3, and sleeve 4 is worn out at copper post 4 top to during crowded metallic channel 5 of going into, copper post 4 top is the toper, more is fit for breaking the insulating layer 61 on wire 6 surface, and copper post 4 is connected with the inside conductor 62 of wire 6.

The bottom of the internal channel 31 of the wire column 3 is provided with a second guide surface 311, the guide surface is a conical surface, the diameter of the internal channel 31 of the wire column 3 is smaller than the diameter of the connecting channel 21, and the diameter of the channel 31 is smaller than the diameter of the wire 6 because the diameter of the connecting channel 21 is matched with the diameter of the wire 6. The opposite both sides of passageway 31 are provided with fretwork post 32, and fretwork post 32 is the trapezoidal face, and down runs through second direction 311 faces one side, and when wire 6 inwards crowded, the shell of wire 6 can be slightly less than the passageway 31 crowded of outer sleeve 1 and sleeve 2 connecting channel 21 and fall, and the shell of being crowded and fallen then discharges through the fretwork post 32 of both sides, guarantees that the contact of internal face and copper post 4 is complete, avoids contact failure.

This female arranging is in advance on the wire 6 of clearance lamp, when needs wiring, wire 6 slides to the connecting channel 21 in the middle from the first spigot surface 211 of bottom, squeeze into towards connecting channel 21 in, when the current section wire 6 got into connecting channel 21, because the diameter of passageway 31 is less than connecting channel 21, consequently fretwork post 32 can extrude the insulating layer 61 on wire 6 surface, peel off insulating layer 61, expose conductor 62 wherein, when wire 6 extrudes inwards once more, fretwork post 32 peels off insulating skin 61 completely, wire 6 direct touch copper post 4, and the top of copper post 4 breaks wire 6 surface insulating layer 61 in the top wire groove 5, direct and internal conductor 62 contact, thereby guarantee that both contact are inseparable.

When raining, because the concave platform 11 is arranged between the boss 12 and the outer casing 1, rainwater can not flow upwards along the concave platform 11 after flowing down from the top, but directly flows to the ground, and the wiring position is not influenced by water flow to cause a water immersion short circuit.
