Abstract

The present invention provides a kind of sensor of compensation thermal deformation, compensates for the change in size of thermal deformation, has effectively contained that shell and socket produce relative rotation in huge temperature alternating, belongs to sensor structure, tooling technical field.The outer edge of socket at the sensor closing in is provided with multiple grooves, seaming tool is correspondingly arranged multiple grooves, when sensor socket and its shell are closed up, the groove of the socket is meshed with the groove of the seaming tool, seaming tool is crimped, and then make the outer peripheral groove of socket and shell interior side contacts, it completes to close up.

Description

A kind of sensor of compensation thermal deformation

Technical field

The present invention relates to a kind of sensor, more particularly to a kind of sensor of compensation thermal deformation belongs to sensor structure, work Fill technical field.

Background technology

The socket of sensor forms sensor unit after crimping closing in metal shell.It is required that crimping is secured, therebetween It should be able to bear enough torques.Under room temperature, existing structure, tooling are fully able to meet the requirements.But working sensor moment temperature Degree can reach+150 DEG C, and aluminium shell differs greatly with engineering plastics shell Thermal Contraction Coefficient, cause to have at the two closing in opposite Rotation, product failure.

Invention content

The present invention provides a kind of change in size compensating for thermal deformation, has effectively contained that shell and socket are handed in huge temperature The sensor to produce relative rotation when change.

The outer edge of a kind of sensor of compensation thermal deformation of the present invention, the socket 1 at the sensor closing in is provided with Multiple grooves 2, seaming tool are correspondingly arranged multiple grooves, when sensor socket 1 and its shell 3 close up, by the socket 1 Groove 2 be meshed with the groove of the seaming tool, crimped, so make 1 outer peripheral groove 2 of socket in shell 3 Side contacts are completed to close up.

Preferably, outer peripheral multiple grooves 2 of the socket 1 are uniformly distributed.

Preferably, the outer edge of the socket 1 is the outer lateral edges of the socket 1.

Above-mentioned technical characteristic may be combined in various suitable ways or be substituted by equivalent technical characteristic, as long as can reach To the purpose of the present invention.

The beneficial effects of the present invention are the present invention is provided with multiple grooves in socket outer edge, and seaming tool also designs There is the groove of opposite engagement.It is mutually crimped with the groove of the socket 1 of sensor using the seaming tool, socket is pushed into shell 3, Crimping cup depth compensates for the change in size of thermal deformation, and groove and 3 interior side contacts of shell of socket 1 have effectively contained shell It produces relative rotation in huge temperature alternating with socket.

Description of the drawings

Fig. 1 is the structural schematic diagram of socket at inventive sensor closing in；

Fig. 2 is the assembly relation schematic diagram of socket 1 and closing in shell 3 at inventive sensor closing in；

Fig. 3 is that socket 1 assembles the schematic diagram for crimping closing in afterwards in place with closing in shell 3 at inventive sensor closing in.

Specific implementation mode

Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete Site preparation describes, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on Embodiment in the present invention, those of ordinary skill in the art obtained under the premise of not making creative work it is all its His embodiment, shall fall within the protection scope of the present invention.

It should be noted that in the absence of conflict, the feature in embodiment and embodiment in the present invention can phase Mutually combination.

The invention will be further described in the following with reference to the drawings and specific embodiments, but not as limiting to the invention.

Illustrate present embodiment in conjunction with Fig. 1 to Fig. 3, a kind of sensor of compensation thermal deformation described in present embodiment, institute The outer edge for stating the socket 1 at sensor closing in is provided with multiple grooves 2, and seaming tool is correspondingly arranged multiple grooves, will pass When sensor socket 1 closes up with its shell 3, the groove 2 of the socket 1 is meshed with the groove of the seaming tool, is pressed It connects, and then makes 1 outer peripheral groove 2 of socket and 3 interior side contacts of shell, complete to close up.

30 grooves 2 at the edge of socket 1 are uniformly distributed at the sensor closing in of present embodiment.

The edge of socket 1 is the seamed edge of socket 1 at the sensor closing at the sensor closing in of present embodiment.

Present embodiment is provided with 30 grooves in socket outer edge, as shown in Figure 1, closing in shell is also designed with opposite nibble The groove of conjunction, by the assembly of socket 1 and closing in shell 3 at sensor closing in, as shown in Fig. 2, after assembly, using with groove knot The seaming tool of structure carries out crimping closing in socket and shell, as shown in Figure 3.Crimping cup depth compensates for the size of thermal deformation Variation, groove and 3 interior side contacts of shell of socket 1 have effectively contained that shell generates relatively with socket in huge temperature alternating Rotation.
