Miniature overcurrent/overheat protector is widely used in the field of the overheated/overcurrent protections such as all kinds of motors, PCB circuit board, electric heating products, battery.
Existing miniature overcurrent/overheat protector volume is large, and technique is more original, inefficiency, and its structure is suitable for manual manufacture, causes quality characteristic to stablize and differs, for example: flashing with feel of product corrected, and conduction problem is not many, failure welding problem etc.; On the other hand, cost of labor is high, and factory cost is difficult to fall.These problems are the bottlenecks of whole industry all the time; Secondly, import equipment costliness.
Summary of the invention
The purpose of this utility model is that a kind of small size thermal protector will be provided.
For achieving the above object, the utility model is implemented according to following technical scheme:
A kind of small size thermal protector, comprise base, the first binding post, static contact and thermal sensitive piece, the first binding post and static contact electrical connection, described the first binding post, the second binding post and static contact are arranged in base, the outside that one end of the first binding post, the second binding post and static contact is separately positioned in base, the other end extends to base; Described base top is provided with thermal sensitive piece, the far-end top that one end of thermal sensitive piece is fixed on base top, the other end and static contact joins, the far-end top of described thermal sensitive piece arranges stator, two rivets are set on stator one end fixes itself and static contact,, other end lower surface arranges projection, the bottom of described projection and thermal sensitive piece upper surface join.
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, described projection is arranged on the lower surface of higher step face.
Compared with prior art, the beneficial effects of the utility model:
Use material strip mode, facilitate accessory automatic machinery to process, and guarantee element size consistency, be finally convenient to machine automatic Composition finished product;
The first binding post and the second binding post flush, and weld two lead-in wires while facilitating automatic welder(welding machine) together with the time;
Base adopts injection moulding, saves traditional man-made assembly base, consumption manpower consuming time, and have loosening and loss, integral type injection moulding has guaranteed firm and insulating requirements;
Diplopore location and Laser Welding are reinforced, and have guaranteed dimensional accuracy and the firm welding degree of riveted joint, can reduce resistance;
Stator has changed armrest sense in the past and has regulated temperature drift and pressure size, synchronous etc., and stator is independent changes stator projection on thermometer in machine, just can realize adjusting; With different according to the height of product temperature section, add default protruding height in man-hour at stator, realize the high qualification rate of product.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model;
Fig. 2 is vertical view of the present utility model;
Fig. 3 is use state diagram of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, the utility model is further described, is used for explaining the utility model in illustrative examples and the explanation of this utility model, but not as to restriction of the present utility model.
Small size thermal protector as shown in Figure 1 and Figure 2, comprise base 8, the first binding post 1, static contact 9 and thermal sensitive piece 4, the first binding post 1 and static contact 9 are electrically connected, described the first binding post 1, the second binding post 10 and static contact 9 are arranged in base 8, the outside that one end of the first binding post 1, the second binding post 10 and static contact 9 is separately positioned in base 8, the other end extends to base 8; Described base 8 tops are provided with thermal sensitive piece 4, the far-end top that one end of thermal sensitive piece 4 is fixed on base 8 tops, the other end and static contact 9 joins, the far-end top of described thermal sensitive piece 4 arranges stator 6, two rivets 5 are set on stator 6 one end fixing to itself and static contact 9, other end lower surface are arranged to projection 7, described protruding 7 bottom and thermal sensitive piece 4 upper surfaces join.Stator 6 has changed armrest sense in the past and has regulated temperature drift and pressure size, synchronous etc., and stator 6 is independent changes the projection 7 of stator 6 on thermometer 4 in machine, just can realize adjusting; According to the height difference of product temperature section, add the height of default projection 7 in man-hour at stator 6, realize the high qualification rate of product; Two rivets 5 by static contact 9 and stator 6 fixing after, and by laser welding, guaranteed dimensional accuracy and the firm welding degree of riveting, can reduce resistance.In addition, all spare and accessory parts adopt material belt type, can facilitate accessory automatic machinery to process, and guarantee element size consistency, are finally convenient to machine automatic Composition finished product.
