Further, two riveting feet on two sides of the metal shell and a square hollowed-out window are respectively arranged on the front patch foot, a triangular bulge is respectively arranged between the riveting feet on two sides of the rubber coating body and the front patch foot track, the direction facing the riveting feet is in a slope shape, and after the riveting feet and the patch feet are pressed into the rubber coating body, the square hollowed-out window is clamped into the triangular bulge in the riveting foot track on the rubber coating body to increase the matching strength of the metal shell and the rubber coating body.

Further, two circular holes are formed in the metal shell, two cylindrical protrusions are arranged at corresponding positions on the rubber coating body, and after the metal shell is pressed in, the circular holes are sleeved into the cylindrical protrusions of the rubber coating body so as to ensure that the concentricity of the axle center and the body is further ensured without walking after the metal shell is riveted.

Further, the encapsulation body is PPS or PA66.

By adopting the technical scheme, the pin type structure is redesigned into the patch type structure, so that a customer can design the circuit board into a single-sided board, or other components can be designed on the back of the sensor, the product cost is reduced, and the circuit board is designed to be more compact and small; in order to adapt to the welding process of the patch, the plastic material is changed into a material which can adapt to reflow soldering, the bonding strength of each assembly is not ensured, and the metal shell is used for fixing at the periphery.

Description of the drawings:

the utility model is described in detail below with reference to the attached drawings:

FIG. 1 is a schematic diagram of an exploded construction of the present utility model;

FIG. 2 is a schematic diagram of the combined structure of the present utility model;

fig. 3 is a schematic side view of the present utility model.

The specific embodiment is as follows:

the utility model is described in detail below with reference to the attached drawings and examples:

fig. 1-3 illustrate an embodiment of the present utility model.

The high temperature resistant patch type position sensor comprises a high temperature resistant rubber coating body 1 (PPS or PA 66), a carbon sheet 2, a terminal 3, an axle center 4, a brush 5 and a metal shell 6, wherein the carbon sheet 2, the terminal 3, the brush 5 and the axle center 4 are mutually matched and arranged in the rubber coating body 1, and the metal shell 6 is fixed outside the rubber coating body 1; the terminal 3 and the metal shell patch foot are bent and formed to form a patch structure and are flush with the bottom of the rubber coating body 1; four inwardly bent riveting feet 61 and an outwardly bent patch foot 62 are downwards extended from the top of the metal shell 6, a concave track 11 is reserved at the matched position of the encapsulation body 1, the four riveting feet 61 and the patch foot extend into the track 11 respectively, tail bending 63 of the riveting feet hooks the encapsulation body 1 to fix the metal shell 6, and the stability of the patch structure of the outwardly bent portion of the patch foot 64 and the terminal after the patch is positioned in the opposite direction.

Further, two riveting feet on two sides of the metal shell 6 and a square hollowed-out window 65 are respectively arranged on the front patch foot, triangular protrusions 12 are respectively arranged on two sides of the rubber coating body 1 and in the middle of riveting foot tracks on the top of the rubber coating body, the directions of the riveting feet and the patch feet are in a slope shape, and after the riveting feet 61 and the patch feet 62 are pressed into the rubber coating body 1, the square hollowed-out window 65 is clamped into the triangular protrusions 12 in the riveting foot tracks on the rubber coating body to increase the matching strength of the metal shell 6 and the rubber coating body 1.
