Abstract
The utility model discloses a novel magnetic switch, comprising a tube and wires. Electrode contacts are arranged at a breaking point of the wires, metal granulars are scattered at a bottom of the tube. The electrode contacts are made of conduction and non-magnetic materials, and the metal granulars are made of magnetic and conduction materials. The utility model has low cost, stable security and excellent conductivity.
Description
Technical field
The utility model relates to a kind of circuit connecting mechanism, relates in particular to a kind of novel magnetic switch.
Background technology
The magnetic switch of current use generally is a tongue tube, and full name is " a dry type tongue open pipe ".Tongue tube inside have one group can magnetic conduction, the reed that can conduct electricity again, with the glass shell encapsulation, the inside is filled with inert gas.When tongue tube was subjected to the action of a magnetic field, the reed in the pipe was magnetized, and circuit is connected in the contact of just attracting each other.When surrounding magnetic field disappeared, reed just leaned on the spring return original state of self, with circuitry cuts.But this tongue tube exists following weak point, 1) the material requirements height of contact reed, the cost height; 2) the contact reed in the pipe disconnects in the closed motion process at long-time and circuit, and the elastic force of reed lost efficacy easily, and caused tongue tube to be scrapped; 3) gap between the reed is subjected to the influence of tongue tube volume, and the gap is less, poor stability.4) service time long, reed is oxidized, loses electric action, causes tongue tube to be scrapped.
The utility model content
The utility model has overcome weak point of the prior art, provides that a kind of cost is lower, safety and stability, the novel magnetic switch that conducts electricity very well.
To achieve these goals, the utility model is by the following technical solutions:
A kind of novel magnetic switch comprises body and lead, is connected to electrode contacts at the place of interrupting of lead, and being scattered in the body bottom has one or several metallic particles.
Described electrode contacts is made for the conduction non-magnet material, and described metallic particles is made for the magnetic conduction electric conducting material.
Owing to adopted technique scheme, the utlity model has following beneficial effect:
Cost is lower, safety and stability, conduct electricity very well, and has increased useful life; Avoided because oxidation loses electric conductivity; Distance between the contact is unrestricted, can be according to actual needs, and the distance between the adjustment contact and the specification of metallic particles have strengthened fail safe and stability greatly.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described and sets forth:
A kind of novel magnetic switch comprises body 1 and lead 2, is connected to electrode contacts 3 at the place of interrupting of lead, and being scattered in the body bottom has one or several metallic particles 4.Described electrode contacts 3 is made for the conduction non-magnet material, and described metallic particles 4 is made for the magnetic conduction electric conducting material.
During use, charge into the magnetic conduction conducting metal particles 4 of pipe volume 1/3rd in pipe, metallic particles 4 can be made size, shape and the quantity of different size according to actual needs.When body was subjected to the action of a magnetic field, the metallic particles 4 in the pipe was subjected to the attraction of magnetic force, moved upward from the pipe end, ran into electrode contacts 3, and just absorption is enclosed on the electrode contacts 3, makes closing of circuit.When surrounding magnetic field disappeared, metallic particles 4 was because the pipe end, fallen back in the effect of gravity again, thereby circuit disconnects, and had realized that circuit is from disconnecting closure, the process of Duan Kaiing again.Otherwise if magnetic switch is inverted, electrode contacts 3 is surrounded by metallic particles 4, and this moment, circuit was a closed circuit.When body was subjected to the action of a magnetic field, the metallic particles 4 in the pipe was subjected to the attraction of magnetic force, moved upward from the pipe end, separated with electrode contacts 3, and circuit is disconnected.When surrounding magnetic field disappeared, metallic particles 4 contacted with electrode contacts 3 because the pipe end is fallen back in the effect of gravity again, closing of circuit, thus realized circuit from closure, disconnect, again Bi He process.
Because metallic particles 4 is contacting with electrode contacts 3, in the process of disconnection, can destroy the oxide layer on electrode contacts 3 surfaces, thereby play self-cleaning effect, and avoid because oxidation loses electric conductivity; Increased useful life; Distance between the electrode contacts 3 is unrestricted, can be according to actual needs, and the distance between the adjustment contact 3 and the specification of metallic particles 4 have strengthened fail safe and stability greatly; Traditional shell all is a tubulose, and the present invention can make difformity as required.
Compared with prior art, the utlity model has following advantage:
Cost is lower, safety and stability, conduct electricity very well, and has increased service life; Avoided because oxidation is lost Remove electric conductivity; Distance between the contact is unrestricted, can according to actual needs, adjust the distance between the contact From with the specification of metallic particles, greatly strengthened safety and stability.
