Abstract
The utility model discloses a wiring pin for a protector. The wiring pin (8) is fixed on a protector base (1) and is provided with spines used for increasing the connecting firmness between the wiring pin (8) and the base and avoiding the wiring pin (8) bouncing in the base (1), and the spines are arranged on two side edges of the wiring pin (8). The wiring pin can be in interference fit with the base (1), the friction force between the wiring pin and the base (1) is increased, and the wiring pin can be effectively prevented from bouncing in the base (1) so as to be firmly fixed in the base (1), therefore, the well adjusted operating temperature of a product is maintained stable, thus guaranteeing stable performance of the protector.
Description
Technical field
The utility model relates to a kind of leg of protector.
Background technology
In external protector technology, two fixed contacts are electrically connected by welding or compound mode and two leg, are referred to as leg and make up, and 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.
The utility model content
The purpose of this utility model is: a kind of leg of protector 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.
The technical solution of the utility model is: a kind of leg of protector, 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 quil of leg play in pedestal.
Described quil is arranged on the dual-side of leg.
The utility model has the advantages that: dependable performance; 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.

The utility model will be further described below in conjunction with drawings and Examples:
Fig. 1 is the structural representation of the protector of application the utility model leg;
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 the utility model leg;
Fig. 5 is the schematic side view of the utility model leg.
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 leg of protector; this leg 8 is fixed in protector pedestal 1, and leg 8 is provided with in order to increase with pedestal degree of being connected firmly, to avoid the quil of leg 8 play in pedestal 1, and quil is arranged on the dual-side of leg 8.
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 utility model 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 utility model, rather than to restriction of the present utility model.In a word, protection range of the present utility model should comprise those conspicuous to those skilled in the art conversion or substitute and remodeling.
Claims (2)
1. the leg of a protector, described leg (8) is fixed in protector pedestal (1), it is characterized in that: described leg (8) is provided with in order to increase with pedestal (1) degree of being connected firmly, to avoid the quil of leg (8) play in pedestal (1).
2. the leg of protector according to claim 1, it is characterized in that: described quil is arranged on the dual-side of leg (8).
