Abstract
The utility model discloses a contactor and a relay without energy-consuming, which belongs to the electric apparatus. The contactor and the relay realize turnon and turnoff by utilizing the interaction between the pulse electromagnetic field and the permanent magnet and the function of the attraction of the permanent magnet and the soft iron or the attracting force caused by the pulse electromagnetic field to the mechanical locking and the releasing mechanisms. The contactor and the relay comprise electromagnets, permanent magnets or telescopic devices with locks, adjustable shelves, springs, connecting pieces, housings, etc. While in use, the current is only started and not kept. Thereby, the efficiency is high, the energy is saved, the coils do not generate heat, and the utility model does not have the alternating current noise. The utility model is suitable for controlling switching, inversion or phase conversion of the current.
Description
Contactor without energy-consuming also is no energy consumption auxiliary relay, and it comprises no energy consumption relay, because inventive concept is identical, purposes is close, all belongs to electrical equipment, be used for Control current break-make, swing to or commutation.
Common contactor relies on electromagnet coil power to generate an electromagnetic field to realize adhesive to connect, and disconnects by spring force during coil blackout, and its shortcoming is need keep the electric current of adhesive, power consumption, coil heating and the unreal AC noise that causes of adhesive is often arranged.
The purpose of this utility model is to design the little contactor of energy consumption, relay, and it is energy-conservation, coil does not generate heat and do not have AC noise.
The purpose of this utility model is achieved in that
A. at middle part unshakable in one's determination or both sides mechanical locking mechanism is installed, promptly resemble one by garden pearl pen full to the brim expansion bend with lock or resemble a click-together expansion bend with lock by a kind of sales counter door usefulness that ejects again, by action finish by pulse electromagnetic suction;
B., permanent magnet more than 1 or 1 is installed in the end of iron core, is repelled each other according to the same polarity of magnetic, the principle that heteropolarity is inhaled mutually utilizes pulse electromagnetic field to cause one to push away one and draw and realize connecting, and realizes disconnecting with the reverse impulse electromagnetic field again.
Compare with common contactor, relay, the utility model only needs starting current, does not need to keep electric current, therefore can be considered as not having energy consumption, coil and not generate heat and noiseless.
Be elaborated below in conjunction with accompanying drawing.Fig. 1. Fig. 2. Fig. 3. be the embodiment that designs according to the utility model.Fig. 1 is the contactor cutaway view that mechanical locking mechanism is housed; Fig. 2 is the contactor cutaway view that permanent magnet is housed; Fig. 3 is the relay cutaway view that permanent magnet is housed; Fig. 4 is a ballpoint pen formula expansion bend cutaway view with lock; Fig. 5 is a cabinet door switch formula expansion bend cutaway view with lock.No matter not having pearl pen type, cabinet door switch formula or permanent magnet all can be contained in and realize locking in Contactor without energy-consuming or the relay or discharge promptly being switched on or switched off.
By shown in Figure 1, Contactor without energy-consuming comprises that relay is made up of coil (1), unshakable in one's determination (2), adjustable shelf (3), spring (4), contact pin (5), casing parts such as (6), mechanical locking mechanism is that mechanical type expansion bend with lock (7) is installed in iron core (2) middle part, also can be installed in both sides;
It is shown in Figure 3 to press Fig. 2, and the magneto locking mechanism promptly uses permanent magnet (18) more than 1 or 1 to be installed in the end of iron core (2).
By shown in Figure 4, expansion bend with lock (7) is by button (8), the revolving part (9) relative with it, little spring (12) that the band muscle shell (10) of these two outsides, the expansion link below the revolving part or pipe (11), its outside are being overlapped and shell (13) formation.
By shown in Figure 5, expansion bend with lock (7) is by the little spring (12) between the groove button with lock (14), the lock hook seat (15) relative with it, these two, lock hook (16) formation that flexibly connects with button with lock and lock hook seat.
For the magneto locking mechanism, its permanent magnet (18) is the magnet steel of neodymium iron boron type, and it is shaped as garden post or sheet, blocks.If coil (1) is 1 group, then should use 2 or 2 groups of permanent magnets (18), its polarity all is being identical near (2) that end unshakable in one's determination.And when coil (1) is 2 groups, then should use 1 or 1 group of permanent magnet (18), and its polarity is being different near (2) that end unshakable in one's determination, still iron core is identical with the polarity of the proximal end iron core (2) of permanent magnet.In addition, there are chamfering or angle, garden in (2) two ends unshakable in one's determination, improving its end magnetic field intensity and magnetic field gradient, thereby strengthen the thrust to permanent magnet, suction.Near the contact pin of Contactor without energy-consuming (5) arc chute can be installed in addition.
Should point out that the magneto locking mechanism is a friction free, and is more superior than mechanical locking mechanism.
Claims (4)
1, Contactor without energy-consuming, by coil (1), unshakable in one's determination (2), adjustable shelf (3), spring (4), contact pin (5), composition such as casing (6) part of etc.ing is characterized in that in the iron core (2), end or both sides are equipped with locking mechanism.
2, according to the described Contactor without energy-consuming of claim 1, it is characterized in that locking mechanism is a mechanical expansion bend with lock (7), be installed in iron core (2) middle part or both sides.
3, Contactor without energy-consuming according to claim 1 is characterized in that locking mechanism is a magneto, promptly uses permanent magnet (18) more than 1 or 1 to be installed in the end of iron core (2).
4, Contactor without energy-consuming according to claim 1 is characterized in that iron core (2) two ends have, chamfering or angle, garden, to improve its end magnetic field intensity and magnetic field gradient.
