Abstract
The utility model relates to an automatic breaking off switch without fuses, which is composed of an upper body, a lower body, power supply guide blocks which are arranged in concave holes on both sides of the lower body, a bimetallic strip, a button, etc. The utility model is characterized in that the bimetallic strip is arranged on one end of one of the power supply guide blocks and extends to one end of another power supply guide block, and the end part of the bimetallic strip is provided with a contact point; the inner part of a middle concave hole of the lower body is provided with the button which is provided with a spring on the top end, and a stop block is arranged in the side direction of the button. When electricity is normally supplied, the stop block is clamped on the lower part of the contact point of the bimetallic strip. When a failure excessive current appears, the bimetallic strip bends upwards; under the action of the spring, the stop block jumps upwards to be tightly pressed against the end surface of the contact point, and the stop block is arranged between the end surface and the power supply guide blocks. Accordingly, when the electricity is switched off, the insulation protection action is reinforced.
Description
The utility model is a kind of low-voltage automatic switche, relates in particular to a kind of moving certainly and takes off no-fuse switch.
No-fuse switch is in recent years in order to replace a kind of reusable apparatus for protecting power supply of meltdown formula fuse; its formation is that mat induced electricity flow is big little; and when overload; make the automatic escape of contact of power supply and produce the protective device of outage; give again after the work to be repaired and restarting; but because of its formation mostly all huger, complex structure, cost is high and can not popularize.
The purpose of this utility model is to design a kind of bimetal leaf type simple in structure and takes off no-fuse switch from moving, so that its volume is little, cost hangs down to be easy to popularize and uses.
The purpose of this utility model is achieved in that from moving takes off no-fuse switch by last, following body, the power supply guide block, the bimetallic shell fragment, buttons etc. are formed, it is characterized in that being provided with respectively the shrinkage pool A of body under the unidirectional perforation in inner two sides of following body, B, be provided with the shrinkage pool of offering to other direction in the middle of it, the shrinkage pool B that shrinkage pool one side is provided with a breach and a side hereinto is conducted, at following body shrinkage pool A, B is provided with the power supply guide block A that stretches out body respectively, B, and at power supply guide block A top binding bimetal leaf, the other end of bimetal leaf extends to the upper end of power supply guide block B and cooperates power supply guide block D that one contact point is set, in the middle shrinkage pool of following body, be provided with the insulation button that a bottom tool protrudes spring, the button lower end is provided with the block that protrudes out to side, this block can with button move down or on move and be sticked in the contact point lower end or fit in the contact point end face and the power supply guide block between, the button outer end coats a holder is set, and holder is fixedly set in, shrinkage pool top in the middle of the following body.
Advantage of the present utility model is: simple in structure, volume is little, cost is low, easy for installation.
With accompanying drawing the utility model is described in detail below.
Description of drawings:
Fig. 1 is a three-dimensional exploded view of the present utility model.
Fig. 2 is a stereogram of the present utility model.
Fig. 3,4 is the utility model user mode figure.
Button stop location schematic diagram when Fig. 5,6 is the utility model user mode.
By Fig. 1～2 as seen, this takes off no-fuse switch from moving and is made up of institutes such as upper and lower body 1,2, power supply guide block, bimetallic shell fragment 4, buttons 6, the shrinkage pool 21 and the shrinkage pool 22 of one unidirectional perforation are set respectively in following body 2 inner two sides, centre at following body 2 is provided with the shrinkage pool of offering to other direction 23, being provided with breach 24 in a side of shrinkage pool 23 communicates with shrinkage pool 22, power supply guide block 31,32 is set respectively in shrinkage pool 21,22, this two guide block stretches out body, and this extension is the usefulness that is connected with loaded article.Link a bimetal leaf 4 on power supply guide block 31 tops, the other end of bimetal leaf 4 extends to the upper end of power supply guide block 32, and corresponding to power supply guide block 32 contact point 41 is set thereon, in the middle shrinkage pool 23 of following body 2, be provided with the insulation button 6 that a bottom tool protrudes spring 5, button 6 lower ends are provided with the block 61 that side protrudes out, the outer end of button 6 coats a holder 7 is set, and holder 7 is fixedly set in shrinkage pool 23 tops in the middle of the body 1,2.
By Fig. 3～6 as seen, when bimetal leaf 4 during in usual use, power supply normally because of power supply guide block 31,32 two ends, this moment, the block 61 of button 6 was in the lower end of contact point 41 by the engaging of bimetal leaf, and this moment, a little was only exposed in fixed bed 7 outer ends (referring to Fig. 3,5) in the top of button 6; When power supply guide block 31; 32 curtage is unusual; during as short circuit or overload; shell fragment 4 ends are subjected to high-tension current and produce high temperature; and influence and make on contact point 41 ends of bimetal leaf 4 curved and leave power supply guide block 32; and cut off the electricity supply; at this moment; block 61 is not stuck because of going up of bimetal leaf 4 is curved; and in the effect of spring 5 and on jump; the otch 62 that button 6 is provided with is arranged on the fixture 7; make this block 61 fit in the end face of contact point 41 and place shell fragment contact point 41 and power supply guide block 32 between, this block 61 is to be made by the insulation material, thereby forms the reinforcement effect of insulation protection.Pushing button because of the bimetal leaf performance recovery again and answer back after pending fault is got rid of is bent downwardly, and make the block 61 of button be sticked in the lower end of bimetal leaf again, and conducting block normally conducts electricity.
