Description
Technical field
The present invention relates to the automatic producing technology field of Protector for electric appliance, particularly a kind of small size thermal protector.
Background technology
Miniature overcurrent/overheat protector is widely used in the field of the overheated/overcurrent protections such as all kinds of motor, PCB, electric heating products, battery.
Existing miniature overcurrent/overheat protector volume is large, and technics comparing is original, inefficiency, and its structure is suitable for manual manufacture, causes quality characteristic to stablize and differs, such as: flashing of product is corrected with feel, and conduction problem is not many, failure welding problem etc.; On the other hand, cost of labor remains high, and factory cost is difficult to fall.These problems are the bottlenecks of whole industry all the time; Secondly, import equipment is expensive.
Summary of the invention
The object of the invention is to provide a kind of small size thermal protector.
For achieving the above object, the present invention implements according to following technical scheme:
A kind of small size thermal protector, comprise base, first binding post, static contact and thermal sensitive piece, first binding post and static contact electrical connection, described first binding post, the second binding post and static contact are arranged in base, the outside that one end is separately positioned in base, the other end extends to base of the first binding post, the second binding post and static contact; Described base top is provided with thermal sensitive piece, one end of thermal sensitive piece is fixed on base top, the other end connects with the distal upper of static contact, above the far-end of described thermal sensitive piece, stator is set, stator one end is arranged two rivets itself and static contact are fixed,, other end lower surface arranges projection, bottom and the thermal sensitive piece upper surface of described projection connect.
Further, described thermal sensitive piece and the electrical connection of the second binding post.
As preferably, described base, the first binding post, the second binding post and static contact are integral type injection mo(u)lding, and the first binding post and the second binding post flush.
Concrete, described thermal sensitive piece is two step surface compositions, and described projection is arranged on the lower surface in higher step face.
Compared with prior art, beneficial effect of the present invention:
Use material strip mode, facilitate accessory automatic machinery to process, and ensure element size consistency, be finally convenient to machine automatic Composition finished product;
First binding post and the second binding post flush, and facilitate automatic welder(welding machine) same to weld two lead-in wires during the time;
Base adopts injection moulding, saves traditional man-made assembly base, consumption manpower consuming time, and has loosening and loss, and integral type injection moulding then ensure that firm and insulating requirements;
Diplopore location and Laser Welding are reinforced, and ensure that dimensional accuracy and the firm welding degree of riveted joint, can reduce resistance;
Stator changes armrest sense in the past and regulates temperature drift and pressure size, synchronous etc., and stator is independent on thermometer, changes stator in the machine protruding, just can realize regulating; Different with according to the height of product temperature section, add at stator and preset protruding height man-hour, realize the high qualification rate of product.
Accompanying drawing explanation
Fig. 1 is front view of the present invention;
Fig. 2 is vertical view of the present invention;
Fig. 3 is using state figure of the present invention.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the invention will be further described, is used for explaining the present invention in illustrative examples of this invention and explanation, but not as a limitation of the invention.
Small size thermal protector as shown in Figure 1 and Figure 2, comprise base 8, first binding post 1, static contact 9 and thermal sensitive piece 4, first binding post 1 and static contact 9 are electrically connected, described first binding post 1, second binding post 10 and static contact 9 are arranged in base 8, the outside that one end is separately positioned in base 8, the other end extends to base 8 of the first binding post 1, second binding post 10 and static contact 9; Described base 8 top is provided with thermal sensitive piece 4, one end of thermal sensitive piece 4 is fixed on base 8 top, the other end connects with the distal upper of static contact 9, above the far-end of described thermal sensitive piece 4, stator 6 is set, stator 6 one end is arranged two rivets 5 and fixing for itself and static contact 9, other end lower surface are arranged protruding 7, the described bottom of protruding 7 and thermal sensitive piece 4 upper surface connect.Stator 6 changes armrest sense in the past and regulates temperature drift and pressure size, synchronous etc., and stator 6 is independent on thermometer 4, changes the projection 7 of stator 6 in the machine, just can realize regulating; Different according to the height of product temperature section, add the height presetting protruding 7 man-hour at stator 6, realize the high qualification rate of product; After static contact 9 and stator 6 are fixed by two rivets 5, and by laser welding, ensure that dimensional accuracy and the firm welding degree of riveted joint, can resistance be reduced.In addition, all spare and accessory parts adopt material belt type, and accessory automatic machinery can be facilitated to process, and ensure element size consistency, are finally convenient to machine automatic Composition finished product.
