Abstract

The utility model relates to a micro-consume energy-saving absorption-release device, comprising coils and a coil framework. A cylindrical soft iron core is arranged in the coils, and a central shaft of the outer side of the coils is provided with an annular permanent magnet. The coils supplied with pulse current can generate a magnetic field, which causes the iron core to generate polarities which can generate same polarity repulsion and opposite polarity attraction to the permanent magnet, and the iron core can generate a movement without continuous power supply to maintain. The utility model does not cause the coils to heat or generate noise, has the advantages of power energy saving, stable and accurate operation and long service life, and can be suitable for the products, such as contactors, electromagnetic valves, relays and switches.

Description

The energy-conservation absorption-release device of little consumption

The utility model relates to a kind of low-voltage electrical apparatus class switch, is electromagnetic field and permanent magnetic field combination are reached purpose of energy saving.

At present, such as electromagnet class switch product in when work once action, control circuit will be to the coil continued power, in consumed power, coil can generate heat and produce noise.In addition, be subjected to the network voltage variable effect, also can cause to release and can not let go, contact trembles etc. that shortcoming, action are clear-cut, poor stability, therefore the life-span of product can reduce.

The purpose of this utility model is to overcome the deficiency of above-mentioned known technology, thereby provides a kind of power consumptive province, noiselessness, action accurately sensitive, the energy-conservation absorption-release device of little consumption of long service life.

The purpose of this utility model realizes in the following way:

This device has coil, and coil has a cylindrical soft iron iron core in the coil rack on coil rack, and wherein: the coil outside is provided with annular permanent magnnet along central shaft.

Annular permanent magnnet can be installed on the baffle plate at two ends of soft iron iron core, and polarity is relative, fix by nut, and reciprocating in coil with iron core.

Annular permanent magnnet can be fixed on the baffle plate at coil two ends along central shaft, and polarity is relative, and the soft iron iron core is positioned at coil rack, and an end links to each other by pin and guide post are coaxial, and guide post passes the permanent magnet and the baffle plate of an end, and it is reciprocating to drive iron core.

Annular permanent magnnet also can be fixed on the baffle plate of coil one end, and the soft iron iron core has spring at the coil other end.

During work, coil is applied pulse current, can form magnetic field in the coil and also make soft iron iron core polarization, produce with the outer permanent magnet of coil that the same sex is inhaled mutually or the opposite sex is repelled each other, form the reciprocating motion of adhesive or release.

The utility model compared with prior art has following advantage:

Owing to increased permanent magnet, changed former low-voltage electrical apparatus coil and generated an electromagnetic field, in moment that startup excites by power consumption, change the polarity of soft iron core and produce adhesive or release with a faint pulse signal, keep its work by permanent magnet again, saved electric energy greatly, eliminated coil heating simultaneously and exchanged noise, in addition, not changed by network voltage and cause to release and can not let go, contact defective such as tremble, action is accurately clear-cut, stability is strong, and improve the useful life of product greatly.

The utility model is described in further detail below in conjunction with drawings and Examples:

Fig. 1 is the utility model structure cutaway view, also is embodiment 1;

Fig. 2 is the utility model second embodiment;

Fig. 3 is the utility model the 3rd embodiment;

Fig. 4 is the utility model the 4th embodiment;

Fig. 5 is the utility model the 5th embodiment;

Fig. 6 is the utility model the 6th embodiment;

Fig. 7 is the utility model the 7th embodiment;

In Fig. 1: (1) coil; (2) coil rack; (3) soft iron iron core; (4), (5) annular permanent magnnet; (6), (7) baffle plate; (8) nut.

(9) guide post in Fig. 3; (10) pin.

In Fig. 5: (11) spring.

Embodiment 1 (see figure 1): pulse current makes in the coil and generates an electromagnetic field, permanent magnet polarity is located at coil two ends and fixing by thicker iron plate and cover relatively, one end and coil magnetic field homopolar-repulsion produce thrust, other end heteropole is inhaled by adhesive mutually and is locked, and changes the then counter motion of direction iron core of pulse current.

Embodiment 2 is identical with embodiment 1 operation principle, and coil is two groups (Fig. 2) in parallel with iron core

Embodiment 7 is identical with embodiment 1,2 operation principles; Coil is two groups of series connection (Fig. 7).

Embodiment 3 (Fig. 3) iron core links by pin is coaxial with guide post, changes the pulse current direction, can make iron core drive guide post and make bidirectional-movement, and annular permanent magnnet is fixed on coil two side shields.

Permanent magnet is located at coil one end among the embodiment 4 (Fig. 4), has spring on the iron core of the coil other end, since iron core one end and permanent magnet adhesive or release, compressible or extension spring, and spring is spacing by the shaft shoulder in the coil rack.

Embodiment 5 (see figure 5)s are identical with embodiment 4 operation principles, and spring is in coil rack, and is spacing by ring in skeleton one end.

Embodiment 6 (see figure 6)s are identical with embodiment 4,5 operation principles, and spring is fixed in the endoporus of iron core one end, and the other end is fixed on outside the baffle plate.

The utility model can be widely used in contactor, electromagnetically operated valve, relay, circuit breaker and switch etc. as a stand-alone product.
