Detailed Description
The structure and operation of the present invention will be described in detail with reference to the accompanying drawings.
A wear sensor probe for an automobile brake pad comprises a probe body, wherein an annular clamping groove 4 is formed in a middle cylindrical surface 2 of a top end surface 1 of the probe body, a metal buckle 3 is fixedly embedded and clamped in the middle cylindrical surface 2, and a clamping pin of the metal buckle 3 is in contact with a substrate surface; the tail part 5 of the probe body is connected with a lead, and a metal protective sleeve 6 is arranged outside the lead.
The alarm wire 7 is a conductor wire, different positions of the alarm wire are placed in the forming die according to different preset alarm positions, and when the probe body is formed in an injection molding mode, the alarm wire 7 is wrapped by the material of the probe body, so that the requirement of functional shapes is met.
The clamping foot of the metal buckle has elastic deformation capacity, the deformation can ensure that the sensor probe is fixed and reliable on the substrate, and the elastic deformation range of the clamping foot of the metal buckle ensures that one probe model can be suitable for the use of various brake pads.
The metal protection sheath is arranged outside the lead at the tail part, the metal protection sheath structure is convenient to mount the metal sheath, and meanwhile, the metal protection sheath can be contracted and tensioned when being subjected to axial tension, so that the metal protection sheath is unlikely to fall off.
The probe body is integrally formed by high-temperature resistant materials. Metal buckle 3 fix in ring groove 4 on middle face of cylinder 2, ring groove 4 has 1 at least, ring groove 4's central line is parallel and equidistant arranges. The position of the annular clamping groove is determined according to the thickness of the steel backing and the position of the alarm wire 7.
Example 1: the lower part of the top end face of the probe is connected with a cylinder middle face, a metal buckle fixing groove is arranged on the cylinder middle face, the tail part is a metal sheath fixing groove, the metal sheath is screwed in and buckled at the tail part of the sensor probe during connection, and a sensor lead is preset at the top end of the sensor probe during integral forming.
