Abstract
A switching device comprises a pull axis with a main spring, while the outer end of the pull axis is stretched out of a shell, the inner end is engaged with a located hook to form a switch resetting-mechanism, wherein the shell is provided with a pin and a stationary contact assembly, while the middle of a corresponding movable contact assembly is fit with the pin to swing, a compression spring is provided between the movable contact assembly and the shell with elastic contact, a boss is provided on the pull axis to engage the movable contact spring assembly, thereby forming a folding actuating device of the movable contact assembly and the stationary contact assembly. The movable contact assembly can sway on the pin to realize the folding and unfolding with stationary contact assembly, with rational working mechanism, non reed and embed element demand, fewer needed accessories, simplified and compact framework, rational location design, the easy assembly and production, high yield, and reduced cost, while the compression spring is exchangeable to improve the contact reliability with the stationary contact assembly.
Description
Technical field: the utility model relates to the switching device that a kind of switch, particularly electrical equipment, instrument are used.
Background technology: general switching device all comprises push shaft, reed, inserts, movable contact spring assembly, static contact assembly etc., the switching of dynamic and static contact opening and closing movement needs push shaft that movable contact spring is pushed away the overbalance point, utilize the moment folding of reed elastic force, the number of spare parts that the switching device of this structure needs is many, complex structure, and the required precision of producing, assembling is very high, and production efficiency is low.
Summary of the invention: at the deficiencies in the prior art, the utility model provides a kind of designs simplification, switching device easy to assembly.
The utility model comprises the push shaft that has main spring, housing is stretched out in its outer end, inner end and location hook cooperate formation switch resetting structure, be provided with pin sheet and static contact assembly in the housing, cooperation is swung in corresponding movable contact spring assembly middle part joining on the pin sheet, the compression spring is arranged on Elastic Contact between movable contact spring assembly and the housing, and push shaft is provided with boss and movable contact spring assembly corresponding matching, constitutes dynamic and static contact folding driving mechanism.
Movable contact spring assembly of the present utility model can be swung the folding of realization and static contact on the pin sheet, actuating mechanism is reasonable, need not reed, inserts etc., the number of spare parts that needs is few, the designs simplification compactness, and location layout is reasonable, Assembling Production is easy, the output height reduces cost, and the compression spring can be so that the contact of dynamic and static contact group be more reliable.
Further specify the utility model below in conjunction with drawings and Examples.
Description of drawings: Fig. 1 is the STRUCTURE DECOMPOSITION schematic diagram of embodiment;
Fig. 2 is the schematic diagram of embodiment switch opens state;
Fig. 3 is the schematic diagram of Fig. 2 closure state.
Embodiment: as shown in Figure 1, push shaft 2 has main spring 3, and housing 1 is stretched out in its outer end, and inner end and location hook 4 cooperate formation switch resetting structure.Be provided with pin sheet 5 and static contact assembly 6 in the housing 1, cooperation is swung in corresponding movable contact spring assembly 7 middle part joinings on pin sheet 5, compression spring 8 is arranged on Elastic Contact between movable contact spring assembly 7 and the housing 1, and push shaft 2 is provided with boss 9 and movable contact spring assembly 7 corresponding matching, constitutes dynamic and static contact folding driving mechanism.Generally also can establish supporting plate 10 above housing 1, convenient like this connection covers push shaft 2, and it is more reliable and stable that push shaft 2 is moved.
When switch opens, as shown in Figure 2, press push shaft 2, push shaft 2 moves contact movable contact spring assembly 7 together with boss 9, make it joining spot wobble around pin sheet 5, movable contact spring assembly 7 constantly pushes compression spring 8 simultaneously, and when movable contact spring assembly 7 process balance points, compression spring 8 is to there being contact one lateral deviation to change also release rapidly, make the dynamic and static closing of contact, 2 lockings under location hook 4 cooperates of push shaft, switch connection enters Fig. 3 state.
Press push shaft 2 again, push shaft 2 go out of lock and under main spring 3 effect outer moving, movable contact spring assembly 7 is swung equally, compression spring 8 deflections release during through balance point, switch opens is returned to Fig. 2 state.In the switch motion process, compression spring 8 can make between dynamic and static contact and keep elastic pressure, contact conduction better reliability.
Can be provided with a plurality of movable contact spring assemblies 7 and corresponding static contact assembly 6 by actual needs in the housing 1 of present embodiment, the convenient so multipole break-make of hilted broadsword that realizes.
Claims (2)
1, a kind of switching device, comprise the push shaft that has main spring, housing is stretched out in its outer end, inner end and location hook cooperate formation switch resetting structure, be provided with pin sheet and static contact assembly in the housing, it is characterized by: corresponding movable contact spring assembly (7) middle part joining is gone up swing at pin sheet (5) and is cooperated, compression spring (8) is arranged on Elastic Contact between movable contact spring assembly (7) and the housing (1), and push shaft (2) is provided with boss (9) and movable contact spring assembly (7) corresponding matching, constitutes dynamic and static contact folding driving mechanism.
