On the basis of the above embodiments, the present invention proceeds with detailed descriptions of technical features and functions thereof, so as to help those skilled in the art fully understand the technical solution of the present invention and reproduce it.

As shown in fig. 1 to 6, in the utility model discloses a braking piece wearing and tearing alarm sensor include pencil plug 1, inductive head 6 and wire 2 at least, pencil plug 1 and inductive head 6 pass through wire 2 and connect, and the afterbody of pencil plug 1, inductive head 6 is leading-out terminal 3. Because the vehicle can cause the vibration and the swing of wire 2 in the driving process, if the swing and the vibration amplitude of wire 2 are too big, the damage of outer insulating skin can appear in the junction with leading-out terminal 3, and the damaged wire easily causes the false alarm of signal, influences car circuit and vehicle safe driving.

In the present invention, in order to solve the above problem, a solution is adopted in which an elastic sheath 4 is sleeved outside or inside the lead 2 at the leading end 3. When the elastic sheath 4 is sleeved inside the insulating layer of the lead 2, the elastic sheath 4 preferably adopts a tubular structure, a single core wire inside can be bent to form a double wire, then the elastic sheath 4 is sleeved and integrated with the wiring harness plug 1 or the induction head 6 in an injection molding mode, and the insulating layer is covered outside the core wire of the wiring harness plug 1 or the induction head 6 after the bending. The insulating layer elastic sheath 4 sleeved outside the lead 2 can adopt a tubular or spiral structure made of metal or nonmetal elastic materials. Specifically, the elastic sheath 4 may be a metal spring or a nonmetal spring such as a rubber spring. When the elastic sheath 4 is a tubular structure, it can be made of a tube body formed by bending a thinner plate body such as phosphor bronze, beryllium bronze, manganese steel or stainless steel, or a tube body made of a non-metal material such as rubber or an injection molding material. Whether the structure is the same spiral structure or the tubular structure as the spring, one end of the elastic sheath 4 needs to be contacted or fixedly connected with the tail part of the wiring harness plug 1, and a certain length of the conducting wire 2 extending out from one side of the outlet end 3 is coated, so that the structure of the part is strengthened. The wiring harness plug 1 and/or the induction head 6 and the elastic sheath 4 can form an integral structure in the injection molding process, and a mode that one end of the elastic sheath 4 is contacted with the outlet end 3 can also be adopted. Under the state that elastic sheath 4 and leading-out terminal 3 contact, when wire 2 swung, the one end of elastic sheath 4 can be in contact with leading-out terminal 3 in the swing in-process first, then reduces the swing range of wire 2 through the deformation of elastic sheath 4.

Of course, on the premise of the above technical measures, the utility model can also be connected with the lead protection tube 7 on the lead 2 at the leading-out end 3. The wire sheath 7 is preferably a tube having thermoplastic properties. Two ends of the wire protecting tube 7 are respectively positioned at two sides of the wire outlet end 3, namely one end of the wire protecting tube 7 is positioned inside the wiring harness plug 1 or the induction head 6, and the other end of the wire protecting tube 7 extends along the length direction of the wire 2. The outer part of the lead 2 at the position of the lead protection tube 7 is sequentially sleeved with the elastic sheath 4 and the outer sheath 5, and the connection strength of the lead 2 at the position contacted with the leading-out end 3 is improved again through the secondary reinforcement of the lead protection tube 7.

The utility model discloses in, oversheath 5 cover in wire 2 and elastic sheath 4 outside, the one end of oversheath 5 is fixed in the afterbody of pencil plug 1 and/or inductive head 6, oversheath 5 is along wire 2 outside extension, its extension length is far greater than elastic sheath 4's extension length, can cover whole wire 2's outside. The outer sheath 5 is used for preventing the wires 2 or the wire harnesses from being polluted by dust and rainwater and being scratched. The structure and shape of the outer sheath 5 are the same as those of the elastic sheath 4.

As shown in fig. 1 to 6, a plurality of groove structures are provided at the tail of the wiring harness plug 1 and/or the inductive head 6 near the outlet end 3, and the groove structures are used for assisting the fixing of the elastic sheath 4 and/or the outer sheath 5.

Finally, although the present description refers to embodiments, not every embodiment contains only a single technical solution, and such description of the present description is for clarity reasons only, and those skilled in the art should make the description as a whole, and the technical solutions in the embodiments can be appropriately combined to form other embodiments that can be understood by those skilled in the art.
