The utility model discloses a realize like this, provide a locating piece, the locating piece is the tetragonal body, the locating piece includes upper supporting part, connecting portion and the under bracing portion of a body coupling, and upper supporting part and under bracing portion do not lie in the upper and lower both sides limit of connecting portion, and upper supporting part and under bracing portion are each other spaced and set up the recess among them, set up the conflict limit of slope at the front end of upper supporting part, are equipped with spacing portion at the surperficial arch of under bracing portion.
The utility model discloses a realize like this, provide a sensor the locating piece as before has been used on the sensor.
Further, the sensor includes shell subassembly, epitheca subassembly and circuit board subassembly, and circuit board subassembly sets up in the casing that shell subassembly and epitheca subassembly are constituteed, and circuit board subassembly includes circuit substrate, sets up on circuit substrate and ends a limit, sets up the mounting hole groove of installation locating piece on the epitheca subassembly, and the lower limb in the mounting hole groove is blocked to spacing portion of locating piece, and the conflict limit butt of locating piece is on ending a limit.
Compared with the prior art, the utility model discloses a locating piece and use sensor of this locating piece, locating piece include a body coupling last supporting part, connecting portion and under bracing portion, go up supporting part and under bracing portion and do not lie in the upper and lower both sides limit of connecting portion, go up supporting part and under bracing portion and separate each other and set up the recess between them, set up the conflict limit of slope at the front end of last supporting part, are equipped with spacing portion in the surperficial arch of under bracing portion. The sensor includes shell subassembly, epitheca subassembly and circuit board subassembly, and circuit board subassembly sets up in the casing that shell subassembly and epitheca subassembly are constituteed, and circuit board subassembly includes circuit substrate, sets up on circuit substrate and ends a limit, sets up the mounting hole groove of installation locating piece on the epitheca subassembly, and the lower limb in the mounting hole groove is blocked to the spacing portion block of locating piece, and the conflict limit butt of locating piece is on ending the limit. Owing to set up the recess for the last supporting part of locating piece has certain cushioning effect when butt circuit substrate, and is not the hard joint, provides the buffering for circuit substrate, prevents its atress damage, reduces unusual incidence, prolongs its life.

Detailed Description
In order to make the technical problem, technical solution and advantageous effects to be solved by the present invention more clearly understood, the following description is given in conjunction with the accompanying drawings and embodiments to illustrate the present invention in further detail. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
Referring to fig. 1 and 2, in the preferred embodiment of the positioning block of the present invention, the positioning block a is a square, and the positioning block a includes an upper supporting portion 1, a connecting portion 2 and a lower supporting portion 3 which are integrally connected. Go up supporting part 1 and lower supporting part 3 and be located the upper and lower both sides limit of connecting portion 2 respectively, go up supporting part 1 and lower supporting part 3 mutual interval and set up recess 4 in the middle of it, set up the conflict limit 5 of slope at the front end of last supporting part 1, at the protruding spacing portion 6 that is equipped with in the surface of lower supporting part 3.
The depth of the groove 4 is larger than half of the height of the positioning block A, so that the upper supporting part 1 and the lower supporting part 3 have certain strength and certain toughness. Due to the arrangement of the groove 4, the upper supporting part 1 and the lower supporting part 3 have certain elasticity, and can play a certain buffering role under the stress condition.
The utility model discloses still disclose a sensor the locating piece as before has been used on the sensor.
Referring to fig. 1 to 7, in the present embodiment, the sensor B is an optical fiber sensor. The sensor B comprises a housing assembly 7, an upper housing assembly 8 and a circuit board assembly 9. The circuit board assembly 9 is disposed in the housing formed by the housing assembly 7 and the upper housing assembly 8. The circuit board assembly 9 includes a circuit substrate 10. The circuit board 10 is provided with a stopper 11, and the upper case unit 8 is provided with a mounting hole groove 12 for mounting the positioning block a. The stopper 6 of the positioning block a is engaged with the lower edge of the mounting hole groove 12. The abutting edge 5 of the positioning block A abuts against the stop edge 11. The positioning block A is clamped in the mounting hole groove 12 by the limiting part 6 after being inserted into the mounting hole groove 12, so that the positioning block A is prevented from loosening.
The stop edge 11 is an inclined oblique edge, and the abutting edge 5 of the positioning block a abuts against the stop edge 11 to simultaneously restrict the movement of the circuit board 10 in the left-right and up-down directions. On the other hand, since the upper support part 1 has a certain buffering function, it not only can provide stress buffering for the circuit substrate 10 to prevent the circuit substrate from being damaged by stress, reduce the abnormal occurrence rate and prolong the service life of the circuit substrate, but also can prevent the circuit substrate 10 from loosening, and simplify the positioning structure of the circuit substrate 10 in the sensor B.
The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
