Problems solved by technology

Therefore wear, cracking and the like can occur on the elastic element 1, so that the sensor 2 falls off
[0005] In addition, if the through hole 5 of the sensor mounting member 4 is formed such that the diameter of the through hole 5 is equal to the lower limit value of the tolerance, as shown in FIG. 5C, the front end 9 of the elastic member 1 for mounting the sensor 2 cannot return to the recessed portion 16 of the sensor protrusion 3, so that the required clamping force to hold the sensor 2 cannot be obtained, so that the sensor 2 may fall off

Embodiment Construction

[0022] figure 1 is a sectional view showing the elastic member 1 for mounting the sensor 2 , which is mounted and temporarily assembled on the sensor protrusion 3 of the sensor 2 . The spring element 1 is inserted together with the sensor projection 3 into the through hole 5 . A through hole 5 is formed on the sensor mounting member 4 . After finishing installing the sensor 2 on the sensor mounting element 4 , the elastic element 1 fastens the sensor 2 in the through hole 5 .

[0023] The elastic element 1 has a hollow portion 40 into which the sensor protrusion 3 of the sensor 2 is to be inserted, and the elastic element 1 is rotationally symmetrical about a central axis along the insertion direction of the sensor protrusion 3 indicated by the arrow. The elastic element 1 consists of a front part 6, a middle part 7 and a rear part 8, integrally made of H-NBR (nitrile rubber containing hydrogen as an additive), said rubber comprising an elastically deformable self-lubricatin...

Abstract

The present invention provides an elastic element for mounting a sensor having a sensor protrusion in a through hole of a sensor mounting element in such a manner that the elastic element is temporarily assembled on the sensor protrusion and is connected to the sensor protrusion. together into the through hole. The elastic member includes a hollow portion and a rear portion having a rear flange and a rim. The rear end flange protrudes from the outer peripheral surface of the rear end portion to be locked on the peripheral portion of one end of the through hole. The rim portion is elastically deformable, and moves from either one or both of a surface of the rear end flange facing the sensor and the other surface of the rear end flange facing the sensor mounting member. Those who stand out.

Description

technical field [0001] The invention relates to a spring element for mounting a sensor with a protrusion. Background technique [0002] The inventors of the present application have been introduced in Japanese Unexamined Patent Application No. 10-122914 (US Pat. No. 5,945,606), which describes a method of mounting a sensor having a protrusion on a Elastic element in the through hole of the sensor mounting element. [0003] As shown in FIG. 5A , the elastic member 1 for mounting the sensor 2 has a hollow portion 40 for mounting the sensor protrusion 3 of the sensor 2 . The elastic member 1 is made by integrally molding together a front end part 6 having a front end protrusion 9 and a front end flange 10, a middle part 7 comprising a cover part sensor protrusion and a rear end part 8. The tapered part 13 and the middle protrusion 14 of the part 3, the rear end part 8 has a rear end flange 17. The elastic member 1 for mounting the sensor 2 is temporarily assembled on the sen...
