Detailed description of the invention
Understanding the technology contents of the present invention for convenience of those skilled in the art, below in conjunction with embodiment and accompanying drawing, the present invention is described in further detail.
As shown in Fig. 1-5 embodiment, described microswitch includes button 1, sealing ring 2, housing 3, spring 4, moving plate 5, rotor contact 6, pole 7, terminal contact 8, base 9 and terminal group 10, and each terminal group includes public terminal, normally closed terminal and three terminals of normally opened terminal.Rotor contact 6 is riveted on moving plate 5 termination.On base 9, one end is provided with two support columns 11, and the other end sets keeps out position 12, sets therebetween normally opened terminal.Pole 7 is placed on base, and one end is located between two support columns, and the other end props up keeps out position 12, has trepanning and be placed on normally opened terminal by trepanning in the middle of pole 7；Moving plate 5 is positioned at the top of pole 7, and moving plate 5 does not rivets has furcation on one end of contact, and two furcations are connected on two support columns 11 of base respectively.What the normally closed terminal in terminal group 10 passed perpendicularly through base keeps out position 12, and bent over to above moving plate termination.Spring 4 two ends catch on moving plate and pole respectively, and moving plate and pole are correspondingly provided with hook hole 52, and moving plate 5 is connected with the normally closed terminal of terminal group by the pulling force action head of spring 4.When pressing under button is by external force, pole 7 keeps out position 12 as fulcrum with base, and the force direction of moving plate 5 is changed by spring 4, makes the contact of moving plate 5 front end leave normally closed terminal and contact with normally opened terminal contact downwards, it is achieved circuit signal switching.
In described microswitch, button, sealing ring, spring, moving plate, rotor contact, pole, terminal contact, base and terminal group etc. are two, the most each button, sealing ring, spring, moving plate, rotor contact, pole, terminal contact, base and terminal group are respectively cooperating with forming the independent signal switching mechanism of two sets and button mechanism, the corresponding signal switching mechanism of each button mechanism.Two set signal switching mechanisms cover in one microswitch of composition in a housing together, and button is assembled on housing by sealing ring.During use, two set signal switching mechanisms are connected in same circuit side by side, and operation either button mechanism makes the signal switching mechanism action of correspondence realize the signal switching in circuit.During use, can only operate one of them button, when one of them signal switching mechanism or button mechanism break down, another switching mechanism action of correspondence can be made by operating another button, it is ensured that the normal work of circuit.Or operation simultaneously two set button mechanism makes the action simultaneously of two set switching mechanisms, if one of them mechanisms fail, another set of mechanism still can maintain the properly functioning of circuit.
Switching mechanism because there being two sets identical and independent in this microswitch is placed in same housing, the uniqueness of output signal it is connected up to by terminal, so, when one of them switching mechanism of this microswitch was lost efficacy, and another switching mechanism may continue to work, output signal is provided, to ensure the integrality of switching function, reaches two-way safeguarding function.
In the present invention, button 1 uses metal headgear to add the form of plastic body, together with metal headgear 1 a is moulded in plastic body 1b, to improve the wearability of button.When this switch application door lock etc., being typically with cam-operated switch button, cam is angled with button-shape, and angle is the biggest, and button abrasion is the most serious, and metal headgear wearability is good, so wide-angle operation application can be suitable for.
Described housing is provided with the hole 31 corresponding with sealing ring bottom shape, and Kong Zhoushe encloses edge, and sealing ring 2 is enclosed with hole along being connected by rivet hot mode, makes hole enclose and realizes sealing along position housing hot melt extruded sealing ring.The corresponding sealing ring integrated injection molding of two set button mechanisms, better tightness.
Keeping out in place of position 12 offsets with pole on base is provided with groove; rotate in termination corresponding to pole is limited in groove and in groove; it is provided with avoiding hollow groove in the middle part of the termination that pole is corresponding, keeps out position die joint that may be present and criticize cutting edge of a knife or a sword avoiding base, it is ensured that mechanism's conversion is reliable and stable.
Above-described embodiment is only the preferably implementation of the present invention, and it describes more concrete and detailed, but therefore can not be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that, for the person of ordinary skill of the art, without departing from the inventive concept of the premise, it is also possible to make some deformation and improvement, these obvious alternative forms belong to protection scope of the present invention.
