Description
Technical field
The utility model relates to a kind of fuse, and more particularly, it relates to a kind of self-recoverage fuse.
Background technology
Fuse, also known as fuse, fuse, is a kind of disposable elements be connected in order to protective circuit on circuit; when circuit power on flow through large time; make metal wire wherein or sheet produce high temperature and fuse, cause opening a way and interruptive current, avoid coming to harm with protective circuit.The fuse manually more renewed is needed to resume operation to make circuit after old blown fuse.
Fuse of the prior art; usually be all be subject to high temperature and directly fuse; thus the protection reached components and parts; fuse in this way; owing to being that the phenomenon that fuses could occur after components and parts are subject to big current work, but the increase of electric current is instantaneous sometimes, but due to the fusing of fuse; not only large to the waste of fuse, and the loss of components and parts is larger.
Utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide self-recoverage fuse, it effectively can solve the phenomenon that fuse of the prior art occurs to fuse after components and parts are subject to transient high-current work, thus causes the waste of fuse and become large problem to components and parts loss.
For achieving the above object, the utility model provides following technical scheme: a kind of self-recoverage fuse, comprise housing, described housing is provided with the inner chamber of cuboid, fuse member is provided with in described inner chamber, described fuse member comprises melt, one end of described melt is connected with one end of inner chamber, the other end of described melt is connected with conduction insertion tube, described conduction insertion tube and the right other end of melt are provided with slippage chamber, described slippage chamber slippage is connected with conduction inserting column, one end that described conduction inserting column is relative with conduction inserting column is the column cap that insulate, the other end of described conduction inserting column opposing insulation column cap is connected with power spring, the other end of described power spring is connected to the other end of inner chamber relative melt, described housing is also provided with the precompressed mechanism of the elastic force for regulating power spring.
By adopting technique scheme, conduction inserting column, under the elastic force effect of power spring, will make conduction inserting column be pressed in conduction insertion tube, realize the normal work of fuse, drawn by a volume principle relevant with pressure and temperature for a certain amount of air, when the temperature of fuse raises, air between slippage chamber and conduction inserting column will expand, relative slippage can be there is in conduction inserting column with conduction insertion tube, when temperature reaches a timing, the current-carrying part of conduction inserting column will be separated with conduction insertion tube completely, insulation column cap will contact with slippage chamber, fuse is made to realize the effect of breaking current, so just can realize, stop the phenomenon fused by fusible link caused when the excessive intensification that causes of transient current, the utilance of fuse is improved greatly, by regulating the precompressed mechanism be arranged on housing, power spring precompression at the beginning can be regulated, by the difference of power spring precompression, the precompression that the pressure that conduction inserting column is ejected in conduction insertion tube also can have more power spring makes corresponding change, again from the principle that the volume of a certain amount of air is only relevant with pressure and temperature, the temperature that conduction inserting column ejects in conduction insertion tube also can along with corresponding change, so, by precompressed mechanism, just the break-off signal of fuse can be controlled, make to change the effect that melt just can reach the break-off signal controlling fuse.
The utility model is set to further: the two ends of described housing are with conductive contact, described precompressed mechanism comprises the sliding plate consistent with described intracavity section shape, the other end of described power spring relative melt is fixedly connected with sliding plate, the other end of described sliding plate facing conductive spring is provided with conducting screw post, one end that described conductive contact is relative with conducting screw post is provided with the screwed hole matched with it, and described conductive contact is set to housing and is rotatably connected.
By adopting technique scheme, make the shape of sliding plate consistent with the cross sectional shape of inner chamber, again because the shape of inner chamber is cuboid, sliding plate is made to slide in the lumen and can not rotate, when rotating conductive contact, the screwed hole being arranged on conductive contact will promote the motion of conducting screw post, thus drive the slip of sliding plate thereupon, and the movement of sliding plate changes making the precompression of the power spring be arranged between sliding plate and slippage chamber, thus realize the effect regulating power spring precompression.
The utility model is set to further: the other end convex of described conduction inserting column opposing insulation column cap is provided with baffle ring.
By adopting technique scheme, the distance making conduction inserting column insert conduction insertion tube can be limited by baffle ring, can not when the elastic force of power spring is excessive, and what conduction inserting column was excessive slips in conduction insertion tube.
The utility model is set to further: be fixedly connected with insulating support rod between described slippage chamber and inner chamber, and described conduction inserting column and power spring are all sheathed on insulating support rod.
By adopting technique scheme, pass through insulating support rod, make conduction inserting column and the weight of power spring when slippage by insulating support rod to bear a part, and can also play guide effect, make conduction inserting column and the state of power spring when slippage more stable.
Compared with prior art, the utility model has the advantage of: effectively solve the phenomenon that fuse of the prior art occurs to fuse after components and parts are subject to transient high-current work, thus cause the waste of fuse and large problem is become to components and parts loss.
