Description

Stitch anti-sticking device of sensor

Technical Field

The utility model relates to a stitch protection architecture of the inside sensor of variable case especially relates to an antiseized mucilage binding of stitch of sensor is put.

Background

In modern society, automobiles have become one of the first-choice transportation tools for the public. The gearbox is one of soul parts of the automobile as an indispensable part of the automobile. A plurality of sensors are arranged in the gearbox, in the traditional scheme, due to the fact that the position of the sensor and the position of a matching plug are limited in the shell of the gearbox, a PIN needle needs to be used for connection in the sensor, but when epoxy resin is filled and sealed, the PIN needle easily climbs a conduction area of the matching end due to a siphon effect. Resulting in unqualified product performance and product rejection. And during the curing process of the resin, air bubbles burst to cause splashing of the PIN needle. Causing the client gearbox to alert that a product needs to be replaced. For automobiles, disassembly and replacement of the transmission sensors is a significant replacement and is expensive. If the PIN needle is because of epoxy climbs gluey sensor inefficacy that leads to, influence whole gearbox function and lead to changing the gearbox, be a very big loss.

Disclosure of Invention

The utility model provides a PIN anti-adhesive device of a sensor, which is convenient to use, can effectively prevent PIN needle from being adhered and reduce the risk of product failure; the technical problem of sensor encapsulating back stitch glue that exists among the prior art easily to lead to the product to become invalid is solved.

The above technical problem of the present invention is solved by the following technical solutions: the utility model provides an antiseized mucilage binding of stitch of sensor, includes the casing, the casing include shielding part and fixed part, shielding part and fixed part between be equipped with and be used for the joint to connect the draw-in groove of inserting the end at the sensor, shielding part in be equipped with the stitch and hold the chamber, shielding part is located inserting of sensor and connects the end, shielding part's lateral surface and sensor connect to be equipped with the clearance between the end inner wall. The shielding part is located the end of inserting of sensor, covers the stitch, and is isolated with the stitch, and when carrying out the encapsulating, glue flows in from the gap between the end inner wall of inserting of shielding part and sensor, prevents that glue from gluing to the stitch, reduces the product risk of becoming invalid. The shell is fixed on the shell wall of the sensor plug-in end through the clamping groove, and the sensor plug-in end fixing device is simple in structure and convenient to install.

Preferably, the shielding part comprises an inclined guide surface and a vertical shielding surface, the shielding surface is positioned at the outer side of the pin, and the guide surface is positioned above the pin. The distance between the inner wall of spigot is farther with connecing to the spigot, provides bigger encapsulating space, and vertically shelters from the face and is parallel with the stitch, has effectually prevented the influence that glue splashes etc. effectively prevents the adhesion of stitch.

Preferably, the shielding part is provided with a protrusion. The cross section of the plug end of the sensor is in a convex shape, and the convex arrangement ensures that the shielding part of the shell has a certain direction when being inserted, thereby effectively preventing reverse installation.

Preferably, the fixing portion and the shielding portion are integrally formed. Simple structure and convenient forming.

Preferably, the groove width of the clamping groove is not less than the wall thickness of the sensor plug-in end. The shell can be rapidly installed when being installed at the inserting end of the sensor, and is convenient to detach.

Therefore, the utility model discloses an antiseized mucilage binding of stitch of sensor device possesses following advantage: simple structure, the shielding face through shielding portion separates the stitch, when the encapsulating, the viscose can not appear and splash, improves the stability of product, reduces the sensor that leads to and scrapps the problem among the embedment technology process.

Detailed Description

The technical solution of the present invention is further specifically described below by way of examples and with reference to the accompanying drawings.

Example (b):

as shown in fig. 1 and 2, the stitch anti-adhesive device of the sensor comprises a housing 7, wherein the housing 7 comprises a shielding part 6 and a fixing part 4 which are integrally formed. The shielding portion 6 is located inside the sensor receiving end 9, and the fixing portion 4 is located outside the sensor receiving end 9. A clamping groove 3 is formed between the shielding part 6 and the fixing part 4, the groove width of the clamping groove 3 is slightly larger than the wall thickness of the sensor plug end 9, and the shell 7 is conveniently clamped on the plug end 9 of the sensor. The shielding 6 comprises an inclined guide surface 1 and a vertical shielding surface 2, the shielding surface 2 is located outside the pin 8, and the guide surface 1 is located above the pin 8 (as shown in fig. 6). A protrusion 5 is integrally formed at one side of the shielding surface.

As shown in figures 3, 4 and 5, when the shell 7 is clamped on the inserting end 9 of the sensor through the clamping groove 3, one end of the bulge 5 is arranged on the right side of the inserting end 9, the inserting end is in a shape like a Chinese character 'tu', and the bulge 5 just can enter the right side of the inserting end, so that the reverse installation of the shell 7 is effectively prevented. The shielding face 2 is parallel to the plane formed by each pin 8, so that the pins 8 are completely shielded, meanwhile, a gap 10 is reserved between the shielding face 2 and the inner wall of the inserting end, glue filling is facilitated, and the guide face 1 is located above the pins 8, so that a larger space is provided for glue filling. Through the installation of casing, when having effectively prevented the encapsulating, the glue adhesion has improved the stability of product on the stitch, reduces the disability rate.
