Abstract
The utility model discloses a kind of urea pressure sensor upper cover.It includes upper cover body (1), and the upper cover body (1) is equipped with multiple threading holes (2), it is characterized in that：The glue groove (3) for being used to accommodate fluid sealant for protruding from upper cover body (1) upper surface is fixedly installed around the threading hole (2) in upper cover body (1) the top correspondence, the glue groove (3) encloses the threading hole (2) inside it.The utility model is simple in structure, by setting glue groove on upper cover body, in follow-up assembling process can in glue groove filling and sealing glue, on the one hand filling fluid sealant can seal sensor, prevent liquid from causing sensor failure into sensor internal, on the other hand harness can be fixed by fluid sealant, it can effectively prevent harness from presenting folding during subsequent applications or rock the situation for causing that harness interrupts or harness bottom solder joint snaps, effectively avoid product function from failing, the failure rate of product can be substantially reduced.
Description
Technical field
A kind of urea pressure sensor upper cover is the utility model is related to, belongs to sensor technical field.
Background technology
Existing urea pressure sensor upper cover top is planar structure, and the harness of sensor is passed through among upper cover, should
The sensor of kind structure in use, there are the defects of high failure rate, folding is presented mainly due to harness, easily causes line repeatedly
Beam occurs signal disconnecting caused by solder joint snaps because rocking in the bottom of middle fracture or harness, product function is failed,
Influence the normal use of sensor.
The content of the invention
In view of the above defects of the prior art, the utility model provide it is a kind of it is simple in structure, can effectively solve
Certainly the urea pressure sensor upper cover of problem is snapped in the fracture of harness centre or bottom.
The utility model is achieved by the following technical solution：A kind of urea pressure sensor upper cover, including upper cover
Body, the upper cover body are equipped with multiple threading holes, it is characterized in that：In the upper cover body upper part correspondence in the threading hole
Around be fixedly installed protrude from upper cover body upper surface be used to accommodate the glue groove of fluid sealant, the glue groove is by the threading
Enclose inside it in hole.
In the utility model, by setting glue groove on upper cover body, and glue groove encloses threading hole inside it, follow-up
After the completion of assembling product, on the one hand sensor can be sealed using fluid sealant by the filling and sealing glue in the glue groove,
On the other hand harness is fixed by fluid sealant, can effectively prevents harness from presenting folding or rocking during subsequent applications to cause line
The situation that beam interrupts or harness bottom solder joint snaps, avoids product function from failing.
Further, integrally made with the upper cover body for ease of processing and manufacturing, the glue groove.
Interference is produced when further, to prevent installation, the threading hole is in rods arranged in horizontal line, and the glue groove is in ellipse
Shape, the oval major axis are consistent with the orientation of the threading hole.
The beneficial effects of the utility model are：The utility model is simple in structure, by setting glue groove on upper cover body, and
And glue groove is enclosed threading hole inside it, after subsequent product is completed, harness is drawn by the threading hole on upper cover body,
Then on the one hand the filling and sealing glue in the glue groove, the fluid sealant in glue groove can seal sensor, prevent liquid into
Enter sensor internal and cause sensor failure, on the other hand harness can be fixed by fluid sealant, effectively can prevent harness from existing
The situation for causing that harness interrupts or harness bottom solder joint snaps is rolled over or rocked in feedback during subsequent applications, effectively avoids product function
Failure, can substantially reduce the failure rate of product.

Embodiment
The utility model is further described below by non-limiting embodiment and with reference to attached drawing：
As shown in drawings, a kind of urea pressure sensor upper cover, including upper cover body 1, the upper cover body 1 are equipped with more
A threading hole 2, is fixedly installed around the threading hole 2 in the 1 top correspondence of upper cover body and protrudes from upper cover body 1
The glue groove 3 for being used to accommodate fluid sealant of upper surface, the glue groove 3 enclose the threading hole 2 inside it.
Split type structure can be used between glue groove 3 and upper cover body 1 in the present embodiment or using integrative-structure, work as use
During Split type structure, between glue groove 3 and upper cover body 1 can use it is Nian Jie threaded connection or other be fixedly connected with mode.For ease of
Processing and manufacturing, assemble and integrally made with the upper cover body 1 in view of sealing effect, preferably described glue groove 3.
Interference is produced when further, to prevent installation, the threading hole 2 is in rods arranged in horizontal line on upper cover body 1, institute
State that glue groove 3 is oval, the oval major axis is consistent with the orientation of the threading hole 2.
When the utility model is used, upper cover body 1 and the housing parts of urea pressure sensor are assembled together, harness 4
Drawn from the threading hole 2 of upper cover body 1, it is to be installed prepare after, the filling and sealing glue in glue groove 3, after sealing glue solidifying.
The utility model is simple in structure, and by the filling and sealing glue in glue groove 3, on the one hand sensor can be sealed,
Prevent liquid from causing sensor failure into sensor internal, on the other hand harness 4 can be fixed by fluid sealant, can be effective
Prevent harness from presenting folding during subsequent applications or rock the situation for causing that harness interrupts or harness bottom solder joint snaps, effectively keep away
Exempt from product function failure, the failure rate of product can be substantially reduced.
Other parts in the present embodiment are the prior art, and details are not described herein.
