Description

Electromagnetic relay
Technical field
The utility model relates to electronic control device field, particularly relates to a kind of electromagnetic relay.
Background technology
Along with scientific and technological development, electromagnetic relay is applied to various occasions.It is iron pin that the common port pin of traditional electromagnetic relay and yoke are integrated, this common port pin electric conductivity can meet 25A(ampere) ~ 60A overload current, temperature rise be 85 ~ 105 ℃ (degree Celsius), can meet an electric control, industrial machine control processed, light control etc.Yet, as the power supply of electric welding machine, water heater, electromagnetic oven, to control under long-term full load hot conditions and working, common port pin is iron pin, temperature rise can reach 115 ~ 135 ℃, easily burns out shell and causes electromagnetic relay to lose efficacy.
Utility model content
Based on this, the problem that while being necessary for the traditional long-term operation at full load of electromagnetic relay, easy burn-out shell causes relay to lose efficacy, provides a kind of electromagnetic relay, can guarantee using under long-term full-load conditions.
A kind of electromagnetic relay, comprise skeleton, upper electrostatic spring, lower quiet spring, movable contact spring, upper electrostatic spring dead point, lower quiet spring dead point, moving point, armature, yoke, common port copper pin, enamelled wire, described upper electrostatic spring dead point hinge in described upper electrostatic spring, described upper electrostatic spring is fixed on described skeleton, described lower quiet spring dead point hinge in described lower quiet spring, described lower quiet spring is fixed on described skeleton, described moving some twisting is in described movable contact spring, described movable contact spring twisting is in described armature, described movable contact spring is fixed on described yoke, and described common port copper pin twisting is fixed on described yoke.
Above-mentioned electromagnetic relay, common port copper pin twisting is fixed on yoke, has improved the conductance of common port pin, has reduced temperature rise, makes electromagnetic relay can be applicable to full-load conditions and hot conditions.
Accompanying drawing explanation
Fig. 1 is the schematic diagram at a visual angle of electromagnetic relay in an embodiment;
Fig. 2 is the schematic diagram at another visual angle of electromagnetic relay in Fig. 1;
Fig. 3 is that the common port copper pin of the electromagnetic relay in Fig. 1 hinge in the schematic diagram on yoke;
Fig. 4 is that the common port copper pin of the electromagnetic relay in Fig. 1 hinge in another visual angle schematic diagram on yoke.
Embodiment
Below in conjunction with specific embodiment and accompanying drawing, the structure of electromagnetic relay is described in detail, so that it is clearer.
Fig. 1 is the schematic diagram at a visual angle of electromagnetic relay in an embodiment; Fig. 2 is the schematic diagram at another visual angle of electromagnetic relay in Fig. 1; Fig. 3 is that the common port copper pin of the electromagnetic relay in Fig. 1 hinge in the schematic diagram on yoke; Fig. 4 is that the common port copper pin of the electromagnetic relay in Fig. 1 hinge in another visual angle schematic diagram on yoke.
As shown in Figures 1 to 4, a kind of electromagnetic relay, comprise skeleton 1, upper electrostatic spring 2, lower quiet spring 3, movable contact spring 4, upper electrostatic spring dead point 5, lower quiet spring dead point 6, moving point 7, armature 8, yoke 9, common port copper pin 10, enamelled wire 11, this upper electrostatic spring dead point 5 hinge in this upper electrostatic spring 2, this upper electrostatic spring 2 is fixed on this skeleton 1, this lower quiet spring dead point 6 hinge in this lower quiet spring 3, this lower quiet spring 3 is fixed on this skeleton 1, these moving point 7 twistings are in this movable contact spring 4, these movable contact spring 4 twistings are in this armature 8, this movable contact spring 4 is fixed on this yoke 9, common port copper pin 10 twistings are fixed on this yoke 9.
This common port copper pin 10 produces closed-loop paths with this upper electrostatic spring 2, and (the direct conducting effect of electric current in circuit), this common port copper pin 10 and this lower quiet spring 3 produce normal open circuits (in circuit electric current can not conducting effect).When applied voltage, give this enamelled wire 11 and produce electromagnetic force, this common port copper pin 10 produces closed-loop paths (electric current really connects conducting effect in circuit) with this lower quiet spring 3, and this common port copper pin 10 and this upper electrostatic spring 2 produce normal open circuits (in circuit electric current can not conducting effect).
Above-mentioned electromagnetic relay, common port copper pin twisting is fixed on that on yoke, (copper conductance is 1.75x10-8, the conductance of iron is 9.78x10-8, the conductance of copper is higher than the conductance of iron), after the combination of common port copper pin and yoke, resistivity is iron pin resistivity low (leading S and resistance R is reciprocal each other according to R=1/S electricity) than common port, so improved the conductance of common port pin, reduce temperature rise, made electromagnetic relay can be applicable to full-load conditions and hot conditions.
The above embodiment has only expressed several execution mode of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the utility model the scope of the claims.It should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
