Abstract
The utility model relates to a double button type on-and-off switch, which comprises a fixing contact, a movable contact, a reset spring of the movable contact, a conducting button, an unlocking button, a conducting and locking mechanism and an unlocking reset spring. The conducting and locking mechanism is composed of a supporting frame, a locking sliding-vane, and a thrusting spring; the supporting frame is vertical to the axial lines of the conducting button and the unlocking button, and the support frame is crossly bridged on the two buttons; the supporting frame is provided with a slide guide groove of the locking sliding-vane and a thrusting spring seat, the position of which corresponding to the conducting button is provided with a guide groove hole and a cross section, and a pressing head matched with the guide groove hole is movably threaded through the guide groove hole and contacted with the supporting frame of the movable contact. The cantilever support of the conducting button is converted to the guide positioning support on both ends through the structure. When pressed, the conducting button is vertical to the movable contact without swinging, and downwards presses the movable contact. The accurate contact of the three pairs of contacts is ensured, the phenomena of non-synchronous three phases and phase lack are avoided, the phenomena of firing and discharging caused by the weak contact of the slide among the contacts are eliminated, and the service life of the on-and-off switch is extended.
Description
Technical field: the utility model relates to a kind of circuit switch, is a kind of double-button formula on-off switch that is used on the three-phase circuit specifically.
Background technology: double-button formula on-off switch comprises the fixed contact that is arranged on the base, movable contact, the movable contact back-moving spring, and be arranged at the conducting button that has head on the switch enclosure, the unlock button and release back-moving spring and the conducting locking mechanism that have the wedge shape termination, CL94212168.6 discloses a kind of double-button formula on-off switch that the conducting locking mechanism is improved design, its conducting locking mechanism is by being arranged on the bearing support that fuses with switch enclosure on the unlock button lengthwise position, the locking slide plate, thrust spring and the locking boss that is arranged on the conducting button are formed, the locking slide plate is provided with interactional thrust inclined-plane, release knob wedge shape termination, all the time lean in the side of conducting button when pressing conducting button locking lug boss position and locking slide plate when relative at locking slide plate under the effect of thrust spring, the locking slide plate makes the locking of conducting button in rapidly slippage and being buckled on the locking boss under the effect of thrust spring; Press unlock button, the active force that wedge shape termination and the interaction of thrust inclined-plane overcome thrust spring oppositely moves the locking slide plate, the conducting button slide plate button card that goes out of lock, the movable contact back-moving spring when movable contact is resetted also with conducting button top reposition, this double-button formula on-off switch structures compactness, but because an end movable sleeve places the conducting button on the switch enclosure is cantilever-shaped, when pressing the conducting button, the other end can swing and can not guarantee vertically downward, be easy to take place the not contact simultaneously of three pairs of contacts like this, cause the asynchronous and phase shortage phenomenon of three-phase, slippage void is touched also and may be produced the sparking electric discharge phenomena between the contact, add that the locking slide plate leans a side at the conducting button all the time, be easy to partially that this all will influence the useful life of on-off switch with conducting button top.
Summary of the invention: the purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of operation less demanding, and the conducting button does not have vertically that swing moves, and guarantees that three pairs of contacts accurately contact, and has eliminated the double-button formula on-off switch that slippage void is touched between the contact.
For achieving the above object, the technical solution that the utility model adopts is as follows: this double-button formula on-off switch comprises the fixed contact that is arranged on the base, movable contact, the movable contact support, movable contact support back-moving spring, and be arranged at the conducting button that has head on the switch enclosure, the unlock button and release back-moving spring and the conducting locking mechanism that have the wedge shape termination, the conducting locking mechanism is by the bearing support that is fixed on the switch enclosure, the locking slide plate, thrust spring and the latch recess that is arranged on the conducting button are formed, it is characterized in that: described bearing support is vertical with release push button shaft line with the conducting button and across two buttons, bearing support is provided with slippage guide groove and thrust spring seat, corresponding conducting button positions is provided with the guiding slotted eye, the locking slide plate is mounted slidably in the slippage guide groove and across head, one end is provided with the inclined-plane of joining with unlock button wedge shape termination cunning, the other end is connected with thrust spring, the inclined-plane is opposite with the thrust spring force direction, have pin-and-hole on the locking slide plate of corresponding conducting button positions, cross section and guiding slotted eye, the head activity that pin-and-hole coincide is passed the guiding slotted eye and is contacted with the movable contact support with pin-and-hole, and the corresponding locking of head slide plate position was provided with latch recess when the conducting button press put in place.
The double-button formula on-off switch of said structure makes the conducting button change the two ends guide-localization into by cantilever support and supports, when pressing the conducting button, the conducting button does not vertically have swing and presses down movable contact support drive movable contact, when the conducting button press puts in place, the locking slide plate is in the effect lower slider of thrust spring and be stuck in and constitute the conducting locking mechanism in the latch recess, guarantee that three pairs of contacts accurately contact, avoided the generation of the asynchronous and phase shortage phenomenon of three-phase, eliminate between the contact slippage void and touched and issuable sparking electric discharge phenomena, prolonged the useful life of on-off switch; When pushing unlock button, under the interaction on the inclined-plane of unlock button wedge shape termination and locking slide plate end, the locking slide plate oppositely moves and withdraws from latch recess, discharges the conducting button, cut-off switch.
Double-button formula on-off switch of the present utility model, the base of angle bar shape is made by the bending of sheet metal material, the room upper punch of not having installation and technological requirement on the two sides has been pressed with the tongue and groove of reinforcement effect, under equality strength requirement situation, select thin material like this for use, bring into play material effects to greatest extent, save raw material.
The utility model is described in further detail below in conjunction with accompanying drawing, and provide embodiment.
