Description
Technical field
The utility model relates to a kind of fuse, and more particularly, it relates to a kind of self-healing 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-healing 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-healing fuse, comprise housing, described housing is provided with inner chamber, 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.
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.
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.
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.
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.

Embodiment
Referring to figs. 1 through Fig. 2, a kind of self-healing fuse, comprise housing 1, described housing 1 is provided with inner chamber, fuse member is provided with in described inner chamber, described fuse member comprises melt 2, described one end of melt 2 is connected with one end of inner chamber, the other end of described melt 2 is connected with conduction insertion tube 3, described conduction insertion tube 3 other end relative with melt 2 is provided with slippage chamber 31, described slippage chamber 31 slippage is connected with conduction inserting column 4, one end that described conduction inserting column 4 is relative with conduction inserting column 4 is the column cap 41 that insulate, the other end convex of described conduction inserting column 4 opposing insulation column cap 41 is provided with baffle ring 42, the other end of described conduction inserting column 4 opposing insulation column cap 41 is connected with power spring 5, the other end of described power spring 5 is connected to the other end of inner chamber relative melt 2, insulating support rod 6 is fixedly connected with between described slippage chamber 31 and inner chamber, described conduction inserting column 4 and power spring 5 are all sheathed on insulating support rod 6.
According to above-mentioned structure, conduction inserting column 4 is under the elastic force effect of power spring 5, conduction inserting column 4 will be made to be pressed in conduction insertion tube 3, realize the normal work of fuse, and by baffle ring 42, the distance making conduction inserting column 4 insert conduction insertion tube 3 can be limited by baffle ring 42, can not when the elastic force of power spring 5 be excessive, what conduction inserting column 4 was excessive slips in conduction insertion tube 3, thus ensure that conductive plug ensures consistent with the amount of the air in slippage chamber 31, 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 31 and conduction inserting column 4 will expand, relative slippage can be there is in conduction inserting column 4 with conduction insertion tube 3, learnt by formula F=k*x, the maximum pressure that power spring 5 provides occurs in, when the position that the current-carrying part of conduction inserting column 4 is just separated with the slippage chamber 31 of conduction insertion tube 3, drawn by a volume principle relevant with pressure and temperature for a certain amount of air again, before the temperature at fuse reaches the temperature of melt 2 fusing, just the current-carrying part of conduction inserting column 4 can be made to be separated with slippage chamber 31, just can reach the protection to fuse, so when temperature reaches a timing, the current-carrying part of conduction inserting column 4 will be separated with conduction insertion tube 3 completely, insulation column cap 41 will contact with slippage chamber 31, 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.
Further, by insulating support rod 6, make conduction inserting column 4 and the weight of power spring 5 when slippage by insulating support rod 6 to bear a part, and can also play guide effect, make conduction inserting column 4 and the state of power spring 5 when slippage more stable.
The above is only preferred implementation of the present utility model, protection range of the present utility model be not only confined to above-described embodiment, and all technical schemes belonged under the utility model thinking all belong to protection range of the present utility model.It should be pointed out that for those skilled in the art, do not departing from the some improvements and modifications under the utility model principle prerequisite, these improvements and modifications also should be considered as protection range of the present utility model.
