Abstract
The utility model provides a fuse, which comprises a fusing body and a switch which is connected in series with the fusing body, wherein, a drive mechanism of the switch is a cam mechanism. Since the utility model is additionally provided with a switch which is connected in series with the fusing body, the utility model can be used as a switch. When the switch switches on, if the current is oversize, the fusing body can be fused quickly to ensure safety. The fuse can be used as a power switch in a power distribution circuit or be used for a load circuit which infrequently switching on and breaking, and can be also used as circuital overload protection or a loop control switch for general lighting.
Description
The utility model relates to a kind of fuse.
For preventing that circuit from causing danger because of short circuit or overload, need in circuit, add fuse, so that electric current cuts off the power supply rapidly when excessive.General fuse mainly comprises a fuse-link at present, and its shell adopts insulating material, and it only has the function of overload fusing, can not use as switch.
The purpose of this utility model is: a kind of switching regulator fuse is provided, and it had both had the function of at present general fuse overload fusing, can be used as switch simultaneously again and used.
Above-mentioned purpose is achieved by the following technical solution: a kind of fuse, contain a fuse-link and a switch of connecting with this fuse-link.
Owing to set up a switch of connecting, then can be used as switch and use with fuse-link; When switch connection, if electric current is excessive, but then fuse-link quick-break guarantees safety.
The driving mechanism of the switch in the above-mentioned fuse-link can be cam mechanism.
The utility model is described in further detail below in conjunction with accompanying drawing:
Fig. 1 is the circuit theory diagrams of the utility model fuse;
Fig. 2 is the structure chart of the utility model fuse.
The circuit theory of the fuse that the utility model provides such as Fig. 1, it also has a K switch of connecting with this fuse-link 6 except that containing a fuse-link that existing fuse had 6.
Fig. 2 has provided the concrete structure of the fuse-link that the utility model provides.It contains two fixed contacts 2,8, their end connects a binding post 1,7 respectively, wherein the other end of fixed contact 8 is by an end of fuse-link 6 connection moving contacts 5, and fixed contact 2 and moving contact 5 are respectively having a contact 3,4 near free end, and above-mentioned two contacts 3,4 directions are relative.Moving contact 5 is subjected to the control of a drive unit, and this drive unit can make the free end of moving contact 5 move, thereby makes contact 3,4 contacts or disconnection.In the utility model, driving mechanism is a cam mechanism 9, and it contains a cam 91 and a depression bar 92.Shown in Fig. 2 is switch disjunction state, and at this moment, moving contact 5 is subjected to the pressure of depression bar 92 and separates with fixed contact 2, if cam 91 rotates to other direction, then depression bar 92 rises, and moving contact 5 rises its free end because of the elasticity of self, thereby contact 4 is contacted, with 3 with switch connection.
Should be pointed out that for the person of ordinary skill of the art under the prerequisite that does not break away from the utility model principle, can also carry out some kinds to this device and improve or modification, these improvement or modification all should be considered as belonging to protection range of the present utility model.
Claims (2)
1, a kind of fuse contains a fuse-link, it is characterized in that: also contain a switch of connecting with above-mentioned fuse-link.
2, fuse according to claim 1 is characterized in that: described switch is a contact switch that is driven by cam mechanism.
