Summary of the invention
The purpose of this utility model is exactly the deficiency that will solve above-mentioned background technology, a kind of novel electron thermoregulator heating element mounting structure is provided, make that heating element conductors is fixing not easily to get loose and heating element and connector assembly are installed firmly, for the normal operation of the device that adjusts the temperature electronically creates favorable conditions.
For achieving the above object, the following technological scheme of employing of the present utility model: a kind of novel electron thermoregulator heating element mounting structure, comprise cover body, inductor, push rod, heating element and connector terminals, described inductor and push rod are positioned at cover body, it is characterized in that, described push rod the inner is positioned at inductor, outer end is provided with heating element, the wire of described heating element is connected with connector terminals, described heating element and connector terminals be the connector assembly of integrated injection molding formation vertically heating element component on push rod outer end, described connector assembly heating element component is fixed on the sidewall of cover body.
Preferably, faceshield side wall is provided with mounting hole, described connector assembly heating element component inserts described mounting hole and cover body is fixed, and is sealed between described connector assembly heating element component and mounting hole by seal ring.
Preferably, the inwall of described mounting hole is interior step surface, and described connector assembly heating element component outer surface is provided with between outer land terrace with matching; Between the push rod outer surface of described seal ring between connector assembly heating element component interior edge face and mounting hole interior edge face and mounting hole internal surface.
Further, institute's push rod is provided with the push nut of the outside movement of restriction push rod, the claw that described push nut comprises annular matrix and inwardly arranges along matrix inwall circumference interval, described claw is to annular matrix side projection and end encloses the axis hole that formation diameter is slightly less than rod diameter, described push rod is inner passes axis hole from matrix opposite side, and end face and the cover body of described push nut annular matrix opposite side are fitted.
In the utility model, after the wire of heating element welds with connector terminals or rivets, by heating element, connector terminals injection moulding on push rod outer end forms connector assembly heating element component, now the wire of heating element is at the plastics internal fixtion of connector assembly heating element component, breakage or welding can not be caused to come off, and heating element, connector terminals is one-body molded is fixed on push rod outer end, only the push rod with connector assembly heating element component need be arranged on cover body mounting hole during installation, push rod uses the outwards movement of push nut restriction push rod, the between outer land terrace of connector assembly heating element member surface forbids that connector assembly heating element component moves inward, connector assembly heating element component is firmly fixed in cover body.
The utility model structure is simple, easy to use, decreases installation procedure, avoids getting loose of heating element conductors, heating element, connector terminals are firmly fixed in cover body.
By following description also by reference to the accompanying drawings, the utility model will become more clear, and these accompanying drawings are for explaining embodiment of the present utility model.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
As Fig. 1 Figure 2 shows that the existing device structure that adjusts the temperature electronically, be explained in detail in the introduction, repeat no more in this.
As shown in Figure 3-4, the device heating element mounting structure that adjusts the temperature electronically of the present utility model, comprise cover body 1, inductor 2, push rod 3, heating element 4 and connector terminals 5, push rod 3 the inner is positioned at inductor 2, outer end is provided with heating element 4, the wire 10 of heating element 4 is riveted with connector terminals 5 or is welded, and heating element 4, connector terminals 5 are one-body molded vertically on push rod 3 outer end, and injection moulding forms cylindrical connector assembly heating element component 6.
First the wire 10 of heating element 4 riveted with connector terminals 5 inner metal sheets or welded during injection moulding, then forming plug-in unit heating element component 6 by plastics injection moulding, now wire 10 is wrapped in injection-moulded plastic, and breakage or welding can not be caused to come off.Be provided with the mounting hole 11 of connector mounting heating element component 6 in cover body 1, the inwall of mounting hole 11 is the interior step surface outwards risen vertically, and connector assembly heating element component 6 internal end surface is provided with the between outer land terrace 9 coordinated with mounting hole 11 that inwardly declines vertically.Sealed by seal ring 7 between connector assembly heating element component 6 and cover body 1, between push rod 3 outer surface of seal ring 7 between connector assembly heating element component 6 interior edge face and mounting hole 11 interior edge face and mounting hole 11 internal surface.Push rod 3 is provided with the push nut 8 of the outside movement of restriction push rod 3, push nut 8 structure as seen in figs. 5-6, the claw 82 that push nut 8 comprises annular matrix 81 and inwardly arranges along matrix 81 inwall circumference interval, claw 82 is to annular matrix side projection and end encloses formation axis hole 83, axis hole 83 is passed without claw side from the opposite side of matrix in push rod 3 the inner namely, axis hole 83 diameter is slightly less than push rod 3 diameter, and push nut 8 is stuck on push rod 3, and push nut 8 matrix 81 is fitted without the end face of claw side and cover body 1.
During installation, seal ring 7 is assemblied in (or directly assembling on connector assembly heating element component 6) in the mounting hole 11 of cover body 1, plug-in unit heating element component 6 with push rod 3 is pushed in mounting hole 11 from outside to inside, now the between outer land terrace 9 of plug-in unit heating element component 6 the inner coordinates with cover body 1 mounting hole 11, forbid that plug-in unit heating element component 6 inwardly moves, the side of push nut 8 without claw is pushed in face of push rod 3 the inner, until fit without matrix 81 end face of the side of claw and cover body 1, restriction push rod 3 outwards moves, thus the connector assembly heating element component 6 that restriction is fixedly connected with push rod 3 outwards moves, by between outer land terrace 9 with push nut 8 by connector assembly heating element component 6 at cover body internal fixtion, bear spring thrust.
