It will be understood that when an element is referred to as being "fixed" or "disposed" on another element, it can be directly on the other element or intervening elements may also be present. When an element is referred to as being "connected" to another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and the like are used herein for illustrative purposes only and are not meant to be the only embodiment.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this utility model belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model. The term "and/or" as used herein includes any and all combinations of one or more of the associated listed items.

As shown in fig. 1-2, a pre-branching cable comprises a main wire 1, branch wires 2 and a branching shell 3, wherein the main wire 1 comprises a main core 11 and a first insulating sleeve 12 wrapped outside the main core 11, the branch wires 2 comprise a branching core 21 and a second insulating sleeve 22 wrapped outside the branching core 21, the diameter of the branching core 21 is smaller than that of the main core 11, the branching core 21 is connected with the main core 11 through a connecting piece 4, the branching shell 3 is in injection molding wrapping at the joint of the main wire 1 and the branch wires 2, the cross section of the connecting piece 4 is in a V-shaped shape, the branching core 21 is arranged at the closed end of the connecting piece 4, the main core 11 is arranged at the open end of the connecting piece 4, staggered tooth pieces 41 are further arranged on two sides of the open end of the connecting piece 4, and the tooth pieces 41 are arranged in opposite directions. Specifically, in this embodiment, the cross sections of the main line 1 and the branch line 2 are circular, the diameter of the split core 21 is smaller than that of the main core 11, in order to improve the structural strength of the joint of the split core 21 and the main core 11, the original C-shaped connector is redesigned into a V-shaped connector, and it is known that the space between the inner sides of the V-shaped connector 4 is gradually increased from the closed end to the open end, the split core 21 extends from the closed end of the connector 4, the main core 11 extends from the open end of the connector 4, the split core 21 abuts against the outer periphery of the main core 11, the cross sections of the two form an 8 shape, and the split core 21 and the main core 11 can be locked by applying an external force from the open end of the connector 4, and the split core 21 and the main core 11 are both in tight contact with the inner sides of the connector 4.
