Abstract
The invention discloses a proctor wiring pin with an exquisite structure. A wiring pin (8) is fixed with the base (1) of a protector; the wiring pin (8) is provided with convex bracts and calthrops which are used for increasing the connection firmness between the wiring pin (8) and the base (1) and avoiding the movement of the wiring pin (8) in the base (1); the wiring pin (8) is flaky; the convex bracts protrude out of the flaky surface of the wiring pin (8); the convex bracts are positioned on the two side edges of the wiring pin (8); the calthrops are positioned on the two side edges of the wiring pin (8); and the calthrops are arranged on the outer side edges of the convex bracts. By using the wiring pin of the invention, clearance fit can be formed in the base (1) so as to increase the friction force between the wiring pin and the base (1), effectively prevent the wiring pin (8) from moving in the base (1), and fix the wiring pin (8) in the base (1) firmly, then the operation temperature of a product of which the operation temperature is adjusted properly is kept stably so as to ensure the performance stability of the protector.
Description
Technical field
The present invention relates to a kind of protector leg of delicate structure.
Background technology
Be used for compressor of air conditioner, freezer compressor, external protector on the compressor such as the compressor that dries; two fixed contacts are electrically connected by welding or compound mode and two leg; be referred to as the leg combination; two leg combinations are fixed on the pedestal by riveting dress mode, need to keep the firm of leg combination.Two moving contacts are gone up fixed contact with two leg combination recited above respectively and are electrically contacted; two moving contacts are welded on the bimetal leaf; adopt adjustment screw to adjust the bimetal leaf crown height that suppresses operating temperature and recovery temperature; and even regulate the pressure between moving contact and the fixed contact; thereby regulate operating temperature and other performance of protector; moving contact and fixed contact are in normally off; be subjected to surpassing at protector under the situation of the operating temperature of protector and overload current; can automatic shutoff circuit, thus play the effect that protective circuit prevents that compressor from being burnt out.
If but leg is combined in the pedestal because the riveting dress is not firm; play up and down takes place in pedestal; cause the bimetal leaf radian of protector inside to change; the operating temperature of protector will change so; performance changes, and does not have the effect of protection compressor behind the compressor of packing into.
Summary of the invention
The objective of the invention is: a kind of protector leg of delicate structure is provided, and its dependable performance has increased the frictional force with pedestal, can effectively prevent leg play in pedestal, and leg is fixedly secured in pedestal; And then make adjustment move the product operating temperature of temperature well to keep stable, guarantee the stable performance of protector.
Technical scheme of the present invention is: a kind of protector leg of delicate structure, and described leg is fixed in the protector pedestal, and leg is provided with in order to increase with pedestal degree of being connected firmly, to avoid the protruding bud and the quil of leg play in pedestal.
Described leg is a sheet, and protruding bud protrudes from the sheet surface of leg.
Described protruding bud is positioned at the dual-side of leg.
Described quil is positioned at the dual-side of leg.
Described quil is arranged at the outer side edges of protruding bud.
Advantage of the present invention is: leg of the present invention both sides have increased protruding bud and quil; after the riveting dress is finished; leg has formed a kind of interference fit in pedestal; increased frictional force with pedestal; can effectively prevent leg play in pedestal; leg is fixedly secured in pedestal, and adjustment is moved the product operating temperature of temperature well and is kept stable so, thereby guarantees the stable performance of protector.
Description of drawings
The invention will be further described below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of the protector of application leg of the present invention;
Fig. 2 is the structural representation of prior art leg;
Fig. 3 is the schematic side view of Fig. 2;
Fig. 4 is the structural representation of leg of the present invention;
Fig. 5 is the schematic side view of leg of the present invention.
Wherein: 1 pedestal; 2 moving contacts; 3 cover plates; 4 bimetal leafs; 5 adjustment screw; 6 packing rings; 7 springs; 8 leg; 9 nuts; 10 epoxy resin; 11 braces.
Embodiment
Embodiment: as Fig. 4, shown in Figure 5, a kind of protector leg of delicate structure, this leg 8 is fixed in protector pedestal 1, and leg 8 is provided with protruding bud and quil.
As shown in Figure 1; after the riveting dress is finished; leg 8 has formed a kind of interference fit in pedestal 1; increased frictional force with pedestal 1; can effectively prevent leg 8 play in pedestal 1; leg 8 is fixedly secured in pedestal 1, and adjustment is moved the product operating temperature of temperature well and is kept stable so, thereby guarantees the stable performance of protector.
Should be pointed out that for the present invention also to have the embodiment of multiple conversion and remodeling, be not limited to the specific embodiment of above-mentioned execution mode through proving absolutely.The foregoing description is as just explanation of the present invention, rather than restriction.In a word, protection scope of the present invention should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
