Description
Technical field
The utility model relates to thermostat technical field, is specifically related to a kind of mounting structure of thermostat.
Background technology
Thermostat is widely used in electric product, is high, the practical circuit safety parts of performance.There is a kind of thermostat at present; its inside is provided with heat-generating units; when working temperature reaches power-off protection temperature; bimetallic thermal sensitive piece generation kick; thermostat internal circuit is disconnected, and the heat-generating units of conducting simultaneously, makes heat-generating units continue to send high temperature; stop the reinstatement of bimetallic thermal sensitive piece, thus avoid circuit and also do not investigating the danger reclosed in out of order situation.
But above-mentioned thermostat internal structure is complicated, the electrical connection of heat-generating units and conducting terminal needs by conducting element to be that medium has come, not only structure burden, parts are various, add the consumables cost of thermostat product itself, and it is loaded down with trivial details to produce assembly technology, produces assembly technology difficulty and improve, considerably increase production assembly cost.Meanwhile, conducting terminal of the prior art generally adopts rivet to be fixed on thermostat, although fixing comparatively firm, riveting process needs special riveting machine just can complete, and increases the difficulty of producing assembling.This burden, the structure fallen behind all are unfavorable for modern production.
Being not difficult to find out, also there is certain defect in prior art.
In prior art, the structure of thermostat is comparatively complicated, and the first terminal 8 and the second terminal 7 are all what to adopt rivet bottom housing 4.Thus, produce in the operation of assembling and certainly led to staking process, and these parts of rivet must be possessed, product consumptive material is increased, produce assembly technology complicated, and then cause the rising of cost and the decline of conforming product rate.In addition, in prior art, heat-generating units 5 all needs to rely on the conducting element such as sheet metal or spring to complete with the electrical connection of the first terminal 8 and the second terminal 7, the more loaded down with trivial details burden of structure, and assembling parts are various, is unfavorable for producing assembling.
Temperature controller mounting structure of the present utility model then overcomes this problem completely.The first terminal 8 and the second terminal 7 complete assembling by the interference fit between terminal mounting hole 15 and terminal erection column 12, eliminate these parts of rivet completely, thus also eliminate the installation procedure of riveted joint, the production of product is assembled more simplify, only need respectively the first terminal 8 and the second terminal 7 to be press-fited on housing 4 by pressure.In addition, the first terminal 8 and the second terminal 7 have been contacted by the electrode surface of conductive contact with heat-generating units 5 completely with the electrical connection between heat-generating units 5, middle without the need to adding conducting element, not only simplify structure, eliminate conducting element, the process more making production assemble simplifies further, to enhancing productivity, reduce production cost, improve qualification rate all important roles of production assembling.
Refer to Fig. 3 and Fig. 4, as preferably, the terminal mounting hole 15 of described the first terminal 8 and the second terminal 7 is laid with and is no less than 3 interference flanges 20.Interference fit between terminal mounting hole 15 and terminal erection column 12, is actually both needs and occurs that slight deformation come.Terminal mounting hole 15 is subject to the swelling effect of terminal erection column 12 and swells, and terminal erection column 12 is also subject to the effect of holding tightly of terminal mounting hole 15 and compresses simultaneously.The contact-making surface of whole circumference as interference of terminal mounting hole 15 is adopted if simple, terminal mounting hole 15 can be made to produce deformation difficulty, thus make press-fiting in production assembling process become extremely difficult, even likely damage terminal mounting hole 15 or terminal erection column 12 time serious, cause conforming product rate to decline.Adopt the structure of interference flange 20 that the compressional deformation of interference flange 20 then can be made to become relatively easy, be convenient to press-fit, also have good elastic conjunction effect simultaneously.
