Description
Technical field
The invention belongs to electric information product manufacturing and applied technical fields, and in particular to it is a kind of for two-way power supply conversion
Trigger device.
Background technique
Have and is common in seesaw-type clapper-type or linear pen-hold grip formula for the moving contact structure form of two-way power supply conversion
Structure is that linear motion-type cutter holder formula dynamic/static contact closes form-separating or is that rotary-type straight knife clip dynamic/static contact closes form-separating.
Latter two dynamic/static contact closes form-separating and converts to realization two-way power supply, can only be identical dynamic with two groups by way of derivation
The same transmission mechanism of static contact system could be completed.The above two generally use elastic pressuring spring and act on moving contact as contact pressure
Power, then the two generallys use spring leaf and acts on moving contact as contact pressure.Under the premise of identical external force, the above two due to
It is clapper-type structure, the pressure that moving contact is applied to static contact wants small, and then the two using cutter holder formula structure, apply by moving contact
The pressure for being added on static contact is big.
Summary of the invention
In order to solve the above technical problem, the present invention provides a kind of trigger devices for the conversion of two-way power supply, can
Quickly, accurately, reliably implement the conversion of two-way power supply.
The invention is realized in this way it is a kind of for two-way power supply conversion trigger device, including contact supporter A and
Contact supporter B docks the cover to be formed and contact assembly, and the cavity of installation contact assembly, contact assembly are provided in the cover
Magnetic conduction sheet A, quick-break blade A, locating part, quick-break blade B and magnetic conduction sheet B, magnetic conduction sheet A including being sequentially arranged are close to quick-break blade
A, magnetic conduction sheet B are close to quick-break blade B, and two magnetic conduction sheets and two quick-break blades are identical two sections of bending structures, and two
The cavity of the cover is stretched out in the end of magnetic conduction sheet and two quick-break blades, forms two structure of contact terminals；
Between the cavity in four ends and the cover of two magnetic conduction sheets, four springs are respectively set, spring one end is solid
Determine on the cover, the end of one end and magnetic conduction sheet connects；
In the middle part of the appearance of contact supporter B, square groove is offered.
Further, round shape protrusion is set respectively on quick-break blade A and quick-break blade B opposite end.
Further, the bending degree of two sections of bending structures of two magnetic conduction sheets and two quick-break blades is 90 °.
Further, the contact supporter A is fixedly connected with contact supporter B by several screw and nuts.
Compared with the prior art, the advantages of the present invention are as follows: since the structure type of movable contact spring is perpendicular type, and sound is touched
The division of head is cutter holder formula structure, can be realized under same group of main contact system of same transmission mechanism quick between two-way power supply
Conversion.The trigger device that two-way power supply is converted acts on moving contact using elastic pressuring spring into modular organization, is meeting electricity
Under the premise of gas performance, the structure of trigger device is simple, so that simplify using the overall structure of trigger device product,
And it is electrical and mechanical more reliable and more stable.
Detailed description of the invention
Fig. 1 is overall structure perspective view of the explosion of the present invention；
Fig. 2 is overall structure assembling schematic diagram of the present invention；
Fig. 3 is application schematic diagram of the present invention.
Specific embodiment
