Abstract

The utility model relates to a binding type compressor protector which comprises a soleplate. A metal shell is fixed under the soleplate; two conductive rods are insulatively fixed and connected with conducting wires and extend into the inner cavity of the metal shell, wherein one end of one conductive rod, which extends into the inner cavity of the metal shell, is electrically communicated with the soleplate via a conductive sheet, and one end of the other conductive rod, which extends into the inner cavity of the metal shell, is electrically connected with a static contact. A thermosensitive element is fixed at the lower end of the inner cavity of the metal shell. Insulating pipes are sheathed outside the metal shell, the soleplate, the conductive rods and partial conducting wires. The utility model has the advantages that the protector can be fix on a compressor coil conveniently and firmly with high use efficiency and good safety performance.

Description

Strap-on Compressor Protector

Affiliated technical field

The utility model relates to a kind of thermal protector that the compressor coil is protected during too high and current overload in temperature.

Background technology

Thermal protector for protection compressor coil in the prior art is a lot; its technology is also ripe; but when inserting thermal protector in the compressor circuit in the prior art; owing to himself structural reason; on the one hand assembling is complicated, easily causes thermal protector to come off on the other hand or problem such as electric leakage, also has because of core members---and the reason of the shell of protector makes the protector inequality of being heated; in addition between protector and shell connect also complicated, thereby influence the effect of protector.Problem because of temperature-sensitive element also can appear in the protector of prior art in addition, circuit can not be disconnected and makes protector ineffective.

Summary of the invention

The purpose of this utility model be design a kind of simple in structure, can make things convenient for place in circuit and Strap-on Compressor Protector that can safe and efficient use.

The technical scheme that realizes the utility model above-mentioned purpose is: have a base plate, floor below is fixed with metal shell, insulation is fixed with two conducting rods and stretches into the metal shell inner chamber on the base plate, conducting rod is connected with lead, the end that one conducting rod stretches into the metal shell inner chamber conducts by a conducting strip and base plate, another conducting rod stretches into an end and the fixed contact conductive attachment of metal shell inner chamber, the lower end of metal shell inner chamber is fixed with temperature-sensitive element, one end Electricity Federation is connected to the moving contact correspondence and is arranged on the fixed contact below, metal shell, base plate, conducting rod and part lead are with insulating sleeve outward, and conducting strip is the fusible part of fixed resistance.Insulating sleeve can make protector convenient, tie up on the compressor coil securely, sleeve pipe is a heat carrier simultaneously, can make protector more even, experience ambient temperature effectively; Conducting strip is fusible part, when temperature-sensitive element breaks down, also fails when electric current is excessive in the circuit to make dynamic and static contact separation and makes under the situation that circuit disconnects, and current electric current can make the temperature of conducting strip reach its fusing point and fuse circuit is disconnected.

There is the other end of the lead of a conducting rod connection to be fixed with sleeve.Be convenient to electrically connect with external circuitry.

The utility model has the advantages that to bundle protector is convenient, securely to be fixed on the compressor coil that can experience ambient temperature equably and change, sensitivity improves greatly when the utility model is implemented temperature protection; Can prevent also simultaneously that temperature-sensitive element from breaking down and during the excessive open circuit in time of electric current,, thereby improve the service efficiency of protector, improve security performance because of the fusing of conducting strip makes the circuit disconnection.

Description of drawings

Fig. 1 is the structural representation of the utility model preferred forms;

Fig. 2 is the another side structural representation of Fig. 1.

Among the figure, 1 is base plate, and 2 is conducting strip, and 3 is temperature-sensitive element, and 4 is metal shell, and 5 is sleeve pipe, and 6 is lead, and 7 is bimetal leaf, and 8 is conducting rod, and 9 is fixed contact, and 10 is that moving contact 11 is sleeve.

Embodiment

Below in conjunction with description of drawings preferred forms of the present utility model.

Base plate 1 below is fixed with metal shell 4, and insulation is fixed with two conducting rods 8 and stretches into metal shell 4 inner chambers on the base plate 1, and conducting rod 8 is connected with lead 6, has the other end of the lead of a conducting rod connection to be fixed with sleeve 11, is convenient to electrically connect with external circuitry.The end that one conducting rod stretches into metal shell 4 inner chambers conducts with base plate 1 by a conducting strip 2, another conducting rod stretches into an end and fixed contact 9 conductive attachment of metal shell 4 inner chambers, the lower end of metal shell 4 inner chambers is fixed with temperature-sensitive element 3, one end Electricity Federation of the bimetal leaf 7 of temperature-sensitive element 3 is connected to moving contact 10 correspondences and is arranged on fixed contact 9 belows, metal shell 4, base plate 1, conducting rod 8 and part lead are with insulating sleeve 5 outward, and conducting strip 2 is the fusible part of fixed resistance.Insulating sleeve can 5 make protector convenient, tie up on the compressor coil securely, sleeve pipe is a heat carrier simultaneously, can make protector more even, experience ambient temperature effectively; Conducting strip 2 is fusible part, when temperature-sensitive element 3 breaks down, also fails when electric current is excessive in the circuit to make dynamic and static contact separation and makes under the situation that circuit disconnects, and current electric current can make the temperature of conducting strip reach its fusing point and fuse circuit is disconnected.
