Abstract

The present invention relates to an electromagnetic remote-control switch capable of turning off a power supply by remote control. A push type switch and an electromagnetic unlocking part is in an integral structure, and a beat-type electromagnet causes a straight bevel unlocking rod to make longitudinal straight-line motion along the switch for unlocking. The electromagnetic remote-control switch can be used as the power supply switches of various household electrical appliances, such as a television, a sounder, an instrument, etc., and fixed electrical appliance apparatuses with similar application.

Description

Electromagnetic remote-control switch

The present invention relates to a kind of electric switch, particularly a kind of electromagnetic remote-control switch of energy remote-control cut-off power supply.

At present, be applied to the remote power switch of multiple household electrical appliance such as television set, sound equipment, instrument and similar applications holding electrical equipment, almost form for amalgamation entirely, as China Patent No. is " 91200764.8 ", " 91212140.8 ", " 91215036.X " and " 90226968.2 " disclosed romote controlled cut-off power switch, all be under the constant substantially situation of original manual power switch, it carried out amalgamation with electromagnetism release mechanism (or increasing independently auxiliary switch again) by a mounting bracket connect and form.The drawback that the remote power-off switch that forms with this kind method exists is: (1) switch assembly unit connecting link is more, component parts increases, influencing factor to mechanism action increases, and volume is big, Heavy Weight, the switch integral rigidity is poor, install and fix requirement and differ, the switch overall reliability is poor, in actual use, easily cause catastrophic failure, make the switch remote-control cut-off malfunctioning.(2) electromagnetism remote controlled unlocking mechanism fully exposes, and the switch application occasion is restricted, and particularly owing to be easy to adsorb dust after electrical equipment electrostatic interaction and the shutdown cooling, will have a strong impact on the reliability of mechanism, reduces its life-span, causes the switch remote control to be lost efficacy.Be subject under the condition of harmful substance corrosion in coastal outlying moist salt fog area and other, switch be more vulnerable to corrode and lost efficacy.

Purpose of the present invention will provide a kind of integral body, the electromagnetic remote-control switch of sealing, and it can strengthen the integral rigidity of switch and to using the adaptability of environment, improve the reliability of switch, reduces manufacturing cost.

The present invention is achieved in that it is an overall structure that push-button switch and electromagnetism are separated latching segment, be installed on the insulating base, and with cover of meter hood involution in addition, the armature that electromagnetism is separated latching segment is positioned at opening one end of " U " type yoke, the one end stretches in the corresponding aperture on the trip lever, the other end is positioned on the fulcrum of pedestal, in the space of trip lever between pedestal and cover cap, its vertical and switch vertical consistency, the inclined-plane of trip lever one end is positioned at the lock core body place of push-button switch, relative with latch hook, the oblong aperture at trip lever middle part is sleeved on the block of pedestal, and back-moving spring is installed in the oblong aperture.

Below in conjunction with accompanying drawing two embodiment of the present invention are explained in detail.

Fig. 1 is a structural representation of the present invention;

Fig. 2 is latch hook, lock core body and the dynamic structure schematic diagram of separating latching segment;

Fig. 3 the present invention increases the structural representation behind extension rod and the reed;

Fig. 4 is the partial structurtes schematic diagram of extension rod and reed.

Embodiment 1: it is an overall structure that push-button switch and electromagnetism are separated latching segment, be installed on the insulating base (10), and with a cover of meter hood (5) involution in addition, push-button switch is positioned at the preceding storehouse (18) of pedestal.Electromagnetism is separated the back storehouse (22) that latching segment is positioned at pedestal, by yoke (8), coil (7), armature (9), trip lever (4), back-moving spring compositions such as (6), armature is positioned at opening one end of " U " type yoke, the one end stretches in the corresponding aperture (25) on the trip lever, and the other end is positioned on the fulcrum (23) of pedestal.In the space of trip lever between pedestal and cover cap, its vertical and switch vertical consistency, the inclined-plane (24) of trip lever one end is positioned at lock core body (16) to be located, relative with latch hook (2), and the oblong aperture (27) at trip lever middle part is sleeved on the block (17) of pedestal and locates.Chute and block are used for limiting trip lever and make linear longitudinal movement, and block also plays a part to locate when the trip lever motion resets.Back-moving spring (6) is installed in the oblong aperture, and the one end is sleeved on the reference column (28) of trip lever, and the other end is positioned at the block place.

In the time of manually, can move mutually, realize the disconnection of push-button switch and connect locking by the lock core body and the latch hook that are had on the push rod (3).The position of latch hook and lock core body is when push-button switch disconnects, as shown in Fig. 2 (a); During connection, as shown in Fig. 2 (d).

During remote control, when push-button switch was in on-state, the position of trip lever and push-rod lock core body and latch hook was shown in Fig. 2 (d).When needing remote-control cut-off, make appliance circuit produce a pulse voltage by remote controller, be added in the solenoid two ends, adhesive armature drives trip lever and advances, and promotes the latch hook swing with the inclined-plane, shown in Fig. 2 (c), (b), finishes the release action.When trip lever advanced, after yoke and the armature adhesive, the trip lever motion stopped.Push rod withdraws under the effect of stage clip (1), and push-button switch is disconnected, and cuts off the general supply of electrical equipment, after the added pulse voltage of coil is eliminated, electromagnet discharges, and trip lever is return tail end under the effect of back-moving spring (6) static, and the swing of drive armature resets.

Embodiment 2: with reference to Fig. 3, Fig. 4, can also extend two extension rods (14,15) at an end of push rod, two extension rods lay respectively in two grooves of pedestal (19,20).Auxiliary normally opened contact and the auxiliary normally-closed contact be made up of three reeds (11,12,13) are inserted into respectively in the corresponding aperture of pedestal, welding ends stretches out the outside of pedestal, and the movable contact spring upper end of auxiliary normally opened contact and auxiliary normally-closed contact lays respectively at the front end of two extension rods.

In the time of manually, push-button switch is connected, distinguish actuating spring (11,12) by the extension rod that push rod itself is had, auxiliary normally-closed contact is disconnected, and auxiliary normally opened contact closure is finished the required function of appliance circuit, when push-button switch disconnects, push rod is return, and auxiliary normally opened contact and auxiliary normally-closed contact recover it and originally often open normally off.The part that increases becomes the time-program(me) relation with the action of push-button switch, can be used for the control to various signals, as to the control of tv audio signal etc.

The present invention has following effect:

(1) because adopting the integrally closed structure, rigidity is strong, has improved the reliability of switch, has dustproof effect, has improved the lubricated and condition of work of moving link, is conducive to prolong switch life.

(2) the Electromagnetic Solution latch mechanism is because adopting beating type electromagnet, structure dexterity; Straight type, inclined-plane trip lever make whole releasing process simple and flexible along the switch linear longitudinal movement, and be rapidly reliable, and global solution latch mechanism good manufacturability realizes easily, is conducive to reduce cost.

(3) increase and auxiliaryly often to open, behind the normally-closed contact, can use on demand for the user, the range of application, convenient and reliable of switch has been expanded in the increase of switch allomeric function.
