Sliding contact is fixed in the groove of shell, first stationary contact head group (41) of sliding contact is connected by wire (7) with input terminal (31), second stationary contact head group (42) of sliding contact is connected by wire (7) with outlet terminal (32), moving contact group is connected with between first stationary contact head group (41) and the second stationary contact head group (42), moving contact component is the first moving contact group (51) and the second moving contact group (52), described moving contact group is fixed on slide bar, when slide bar be controlled with the coordinated signals of protection switch electrical equipment (1) and slippage time, the break-make between the first stationary contact head group (41) and the second stationary contact head group (42) can be controlled, described first stationary contact head group (41) and the second stationary contact head group (42) comprise three contacts respectively, and constitute the first switch respectively, second switch and the 3rd switch, described, when slide bar be subject to being fixed on torsion spring on shell up sliding along the slide rail on shell time, first switch closes, second switch and the 3rd switch disconnect, when slide bar be controlled with the control of protection switch electrical equipment (1) and slippage downwards time, first switch just disconnects, second switch and the 3rd switch are just closed, at above-mentioned first switch, second switch and the 3rd switch disconnect with closed process, due to the first switch, second switch and the fixed contact corresponding to the 3rd switch are connected on the input terminal (31) and outlet terminal (32) that correspond respectively by wire (7), therefore the first switch, the break-make of second switch and the 3rd switch also control the break-make between corresponding input terminal (31) and outlet terminal (32).
Second embodiment:
Sensitive switch is fixed in the groove of shell, makes its common port be connected to outlet terminal (32) by wire (7), make its normal-closed end be connected to input terminal (31) by wire (7).Just the opposite with the first embodiment; sensitive switch essence is a normally closed switch; when sensitive switch is uncontrolled control with protection switch electrical equipment (1) time; sensitive switch is in closure state, is also in closure state between input terminal (31) corresponding thereto and outlet terminal (32).When sensitive switch be controlled control with protection switch electrical equipment (1) time, sensitive switch is in off-state, is also in off-state between input terminal (31) corresponding thereto and outlet terminal (32).
Sliding contact is fixed in the groove of shell, first stationary contact head group (41) of sliding contact is connected by wire (7) with input terminal (31), second stationary contact head group (42) of sliding contact is connected by wire (7) with outlet terminal (32), moving contact group is connected with between first stationary contact head group (41) and the second stationary contact head group (42), moving contact component is the first moving contact group (51) and the second moving contact group (52), described moving contact group is fixed on slide bar, when slide bar be controlled with the coordinated signals of protection switch electrical equipment (1) and slippage time, the break-make between the first stationary contact head group (41) and the second stationary contact head group (42) can be controlled, described first stationary contact head group (41) and the second stationary contact head group (42) comprise three contacts respectively, and constitute the first switch respectively, second switch and the 3rd switch, described, when slide bar be subject to being fixed on torsion spring on shell up sliding along the slide rail on shell time, first switch closes, second switch and the 3rd switch disconnect, when slide bar be controlled with the control of protection switch electrical equipment (1) and slippage downwards time, first switch just disconnects, second switch and the 3rd switch are just closed, at above-mentioned first switch, second switch and the 3rd switch disconnect with closed process, due to the first switch, second switch and the fixed contact corresponding to the 3rd switch are connected on the input terminal (31) and outlet terminal (32) that correspond respectively by wire (7), therefore the first switch, the break-make of second switch and the 3rd switch also control the break-make between corresponding input terminal (31) and outlet terminal (32).
Above-mentioned connected mode is directly connected by wire (7), by the connected mode of circuit board in conventional art, its overcurrent capability increases, because be by copper coin insert plate in circuit board, and the cross section of copper coin generally does not quite, directly connected by wire (7) and then avoid this problem, the sectional area of wire (7) is larger, its overcurrent capability is also stronger, therefore the overcurrent capability of auxiliary switch of the present utility model (2) strengthens, connected mode of the present utility model does not need extra circuit board customized, compared to the cabling mode of PCB Wound-rotor type, wire can directly be arranged in the groove of shell by the utility model, staggered also passable, therefore relative to the wire laying mode of circuit board cabling of the present utility model, there is the simple feature of structure, and because cabling mode of the present utility model does not need around arrangement, by directly two terminals being connected, reaching by line amount of wire is economized most, manufacturing cost is made to have also been obtained control.
In sum, the utility model is by making sliding contact, being connected by wire between sensitive switch and binding post, instead of the electric connection mode by circuit board in prior art, auxiliary switch is allowed to have better overcurrent capability, and relative to circuit board, the mode structure of direct wiring is convenient, be easy to safeguard, also control production cost.
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.
