Abstract
The utility model discloses an overheat protector of a scroll compressor, which comprises a metal outer shell, an insulation internal shell, a group of fixed contacts and dynamic contacts which are positioned in the insulation internal shell and respectively connected with the wiring welding tablet. The utility model is characterized in that: bimetallic strip that are connected with the metal outer shell are arranged on the bottom of the metal outer shell; the bimetallic are connected with the shrapnels on the dynamic contacts through a top rod. By adopting the scheme, the bimetallic trip can be ensured and reliably control the group of fixed contacts, dynamic contacts to switch on and off power supply in time through temperature changes of the metal outer shell, thus stopping and recovering the work of the compressor when the compressor is overheated as long time working and the temperature of the compressor is up to safe line, thus playing good protection effect on the compressor.
Description
Technical field
The utility model relates to a kind of overheat protector, particularly a kind of overheat protector of scroll compressor.
Background technique
The scroll compressor overheat protector is the auxiliary products of scroll compressor, mainly is in compressor operating, because of working long hours, and temperature overheating, the overheat protector contact disconnects, and compressor quits work; After temperature dropped to guard wire, it is closed that recover automatically the contact, and compressor is worked again, thereby play the effect of protection compressor.
There is defective in the overheat protector of selling on the market on itself designing now, and movable contact is last; stationary contact is down, causes the movable contact shell fragment dynamics that follows the string when the operating time is long, and resistance increases above 5 ohm; cause bad connection, react insensitive, can not play a very good protection.
The model utility content
This practical problem to be solved is; at the deficiencies in the prior art; a kind of scroll compressor overheat protector is provided; its objective is when guaranteeing that compressor reaches guard wire because of work long hours temperature overheating and compressor temperature; can in time disconnect and connect circuit; stop and recovering compressor operating, thereby compressor is played a very good protection.
In order to achieve the above object; the technical solution adopted in the utility model is: a kind of overheat protector of scroll compressor; comprise metal shell, insulation inner casing; be positioned at one group of fixed contact, movable contact that the insulation inner casing is connected with the wiring weld tabs respectively; it is characterized in that: the bottom that is positioned at described metal shell is provided with and the contacted bimetallic strip of metal shell, and described bimetallic strip is connected by pushing up shell fragment excellent and on the movable contact.
The overheat protector of scroll compressor, described bimetallic strip is the arc convex structure that makes progress, its protruding end is connected with the top rod.Described top rod is between movable contact and bimetallic strip, and an end and bimetallic strip salient point are close to, and the other end closely contacts with shell fragment on the movable contact.
The overheat protector of scroll compressor, described metal shell and insulation be provided with between the inner casing be sleeved on the rod of top every electric sheet.
The overheat protector of scroll compressor, described wiring weld tabs is connected with lead-in wire with outside connector assembly respectively.
The overheat protector of scroll compressor, described wiring weld tabs place is provided with the silica gel circle with the metal shell sealing.
The overheat protector of scroll compressor, described top rod is a stupalith.
The overheat protector of scroll compressor, described metal shell are copper material.
The utility model adopts such scheme; when having guaranteed that compressor reaches guard wire because of work long hours temperature overheating and compressor temperature; by the metal shell temperature variation make bimetallic strip reliably control one group of fixed contact, movable contact in time disconnect and connect power supply; stop and recovering compressor operating, thereby compressor is played a very good protection.
Description of drawings:
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
Fig. 1 is the internal structure schematic representation of the overheat protector of a kind of scroll compressor of the utility model;
Fig. 2 is the external structure schematic representation of the overheat protector of a kind of scroll compressor of the utility model;
Be labeled as among Fig. 1: 1, metal shell, 2, the wiring weld tabs, 3, fixed contact, 4, movable contact, 5, the insulation inner casing, 6, the top rod, 7, every electric sheet, 8, bimetallic strip, 9, the silica gel circle; 10, shell fragment; 11, connector assembly; 12, lead-in wire.
Embodiment:
Structure as shown in Figure 1 and Figure 2, the overheat protector of a kind of scroll compressor of the utility model is used to protect compressor to work under normal temperature.
Purpose for the sensitivity that improves overheat protector; the technical solution adopted in the utility model is: a kind of overheat protector of scroll compressor; comprise metal shell 1, insulation inner casing 5; be positioned at one group of fixed contact 3, movable contact 4 that insulation inner casing 5 is connected with wiring weld tabs 2 respectively; the bottom that is positioned at the metal shell 1 that described copper material makes is provided with and metal shell 1 contacted bimetallic strip 8, and described bimetallic strip 8 is made top rod 6 by stupalith and is connected with shell fragment 10 on the movable contact 4.Bimetallic strip 8 is the arc convex structure that makes progress, and its protruding end is connected with top rod 6.Described wiring weld tabs 2 12 is connected with lead-in wire with outside connector assembly 11 respectively, by connector assembly 11 with go between and 12 link to each other with compressor circuit.Wiring weld tabs 2 places are provided with the silica gel circle 9 with metal shell 1 sealing.
The fixed contact 3 of overheat protector is positioned on the movable contact 4, and the top rod 6 of described overheat protector is between movable contact 4 and bimetallic strip 8, and two ends closely contact with bimetallic strip 8 with movable contact 4 respectively.When the compressor long-term work, when temperature raise overheated (above 130 ℃), the bimetallic strip 8 in the overheat protector was heated downwards, made top rod 6 downwards loosening, and movable contact 4 unclamps immediately, breaks away from fixed contact 3, disconnecting circuit, and compressor quits work; When temperature is reduced to 110 ℃, bimetallic strip 8 reinstatements (raised position) will be pushed up rod 6 and be held up, and push up excellent 6 jack-up movable contacts 4, and it is closely contacted with fixed contact 3, the connection circuit, and compressor is resumed work.
The utility model can be regulated bimetallic strip 8 as required in order to enlarge using scope when producing, thereby the disconnection of overheat protector and the temperature of connection circuit are satisfied the demands.
