The rotary make-and-break mechanism is characterized in that the mechanism comprises a housing and a rotating shaft arranged in the housing; a connecting terminal A, a connecting terminal B and a connecting terminal C are arranged on the outer side of the housing; each connecting terminal is respectively connected with a conductive block arranged on the inner side of the housing and in contact with the rotating shaft through a flexible conducting wire and a spring; a conducting strip is arranged on the rotating shaft; the connecting terminal A and the connecting terminal C are connected with a main loop; and an electronic arc extinguishing device is arranged between the connecting terminal A and the connecting terminal B. The rotary make-and-break mechanism has the advantages of simple structure, wide application, long service life and extensive popularization and application, is applicable to various fields such as miniature circuit breakers, isolating switches, changeover switches, contactors, relays, starters, and the like, and is capable of eliminating the arc produced in circuit break.
Description
(1) technical field
The utility model relates to a kind of current switching device, particularly a kind of rotary on off mechanism with the arc extinguishing function.
(2) background technology
The apparatus function of control circuit break-make is single at present, and suitable application area is limited, mode of connection underaction, and it is serious to produce electric arc in the connecting and disconnecting of the circuit process, and the switch contact life-span reduces greatly, and electric arc also may interfere with the operate as normal of other electrical equipment.
(3) summary of the invention
The utility model provides a kind of rotary on off mechanism of widely used band arc extinguishing function in order to remedy the defective of prior art.
The utility model is achieved by the following technical solution:
A kind of rotary on off mechanism with the arc extinguishing function, it is characterized in that: comprise shell and be installed in its inner rotating shaft, the shell outside is equipped with binding post A, binding post B and binding post C, each binding post is connected with the contacted conducting block of rotating shaft with installation with spring inside the shell by the conduction flexible cord respectively, rotating shaft is provided with conducting strip, binding post A is connected major loop with binding post C, between binding post A and the binding post B electronic type arc-control device is installed.
The rotary on off mechanism of this band arc extinguishing function, the electronic type arc-control device is capacitance-resistance absorption plant or piezo-resistance, the electric arc that produces can be eliminated during circuit breaker.The shell inboard is provided with to projecting inward casing guide vane end stop, and the rotating shaft outside is provided with outside protrusion and the corresponding rotor guide vane end stop of casing guide vane end stop, two guide vane end stops cooperate carry out can the countershaft rotation time spacing.
The beneficial effects of the utility model are: the rotary on off mechanism of this band arc extinguishing function, simple in structure, be widely used, can be used for variously miniaturely opening circuit, every field such as isolating switch, change over switch, contactor, relay, starter, and can eliminate the arc phenomenon that produces when opening circuit, long service life is suitable for applying on a large scale.
(4) description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the rotary on off mechanism of the utility model band arc extinguishing function.
Among the figure, 1 shell, 2 rotating shafts, 3 binding post A, 4 binding post B, 5 binding post C, 6 conduction flexible cords, 7 springs, 8 conducting blocks, 9 conducting strips, 10 casing guide vane end stops, 11 rotor guide vane end stops, 12 capacitance-resistance absorption plants, 13 piezo-resistances.
(5) embodiment
Accompanying drawing is a kind of specific embodiment of the present utility model.The rotary on off mechanism of this band arc extinguishing function, it is characterized in that: comprise shell 1 and be installed in its inner rotating shaft 2, shell 1 outside is equipped with binding post A3, binding post B4 and binding post C5, each binding post respectively by conduction flexible cord 6 and spring 7 be installed in shell 1 inboard and be connected with rotating shaft 2 contacted conducting blocks 8, rotating shaft 2 is provided with conducting strip 9, spring 7 makes conducting block 8 and conducting strip 9 excellent contact, binding post A3 is connected major loop with binding post C5, between binding post A3 and the binding post B4 electronic type arc-control device is installed, the electronic type arc-control device is capacitance-resistance absorption plant 12 or piezo-resistance 13.Shell 1 inboard is provided with to projecting inward casing guide vane end stop 10, and rotating shaft 2 outsides are provided with outside protrusion and casing guide vane end stop 10 corresponding rotor guide vane end stops 11.
The rotary on off mechanism of this band arc extinguishing function, when rotating shaft 2 as shown in Figure 1 during the position, contact with conducting strip 9 with the conducting block 8 that binding post A3 is connected with binding post C5, whole major loop is connected, when needs open circuit, rotating shaft 2 clockwise rotates, the conducting block 8 that conducting strip 9 at first is connected with binding post A3 breaks away from, the conducting block 8 that this moment, binding post B4 was connected with binding post C5 is still connected with conducting strip 9, the electric arc that produces is eliminated by capacitance-resistance absorption plant 12 or piezo-resistance 13, rotating shaft 2 is rotated further clockwise, and the conducting block 8 that is connected with binding post B4 until conducting strip 9 breaks away from, and entire circuit opens circuit.When the rotating shaft 2 that is in off state is rotated counterclockwise, the conducting block 8 that conducting strip 9 just can be connected with binding post C5, binding post B4, binding post A3 successively contacts, forward to when casing guide vane end stop 10 limits the position with rotor guide vane end stop 11 and stop operating, entire circuit just can revert to on-state, like this break-make of the rotation realization circuit that circulation just can be by rotating shaft 2, use more efficient and convenient, be easy to people and control.
