Embodiment

For making your juror can know the content of understanding the utility model, sincerely graphic with the description collocation, please consult.

See also Fig. 3 and shown in Figure 4, it is the constitutional diagram and the exploded view of the preferred embodiment of the utility model miniaturized relays.Among the figure, this miniaturized relays 2 is closed in the housing 3, and comprises a bottom base 21, a top base 22, an electromagnet 23, a magnetic moving part 24 and a terminal component 25.

This bottom base 21 has a holding part 211, a slot 212 and a fixed contact contact pin 213.22 of this top bases are one-body molded with this bottom base 21, and have a hollow cylinder 221 and a footstock 222.One end of this hollow cylinder 221 connects this bottom base 21, and the other end connects this footstock 222.212 of this slots are formed at two adjacent side of these bottom base 21 1 sides respectively, form a L type slot.213 of this fixed contact contact pin are arranged at an end of this holding part 211 and to the position that is provided with that should slot 212.

23 of this electromagnets comprise an electromagnet 231, a coil unit 232, one positive pin 233 and a negative pin 234.This positive pin 233 is to electrically connect a cathode power supply (figure does not show), and this negative pin 234 is to electrically connect a negative power supply (figure does not show).This electromagnet 231 is to be column type and to be arranged in this hollow cylinder 221.232 of this coil units are set around outside this hollow cylinder 221.This 233 of positive pin is arranged at this bottom base 21 and electrically connects with this coil unit 232.This negative 234 of pin is arranged at this bottom base 21 and electrically connects with this coil unit 232.In the present embodiment, this electromagnet 231 can silicon steel, the material of tool magnetic conductivity such as pure iron, permalloy or noncrystalline is made.232 of this coil units are can copper cash made, but not as limit.

24 of this magnetic moving parts comprise yoke iron slice 241, an armature plate 242 and a joint fastener 243.This yoke iron slice 241 is to be a L sheet type and the one of which end is the upper side that is arranged at this footstock 222, and is connected with an end of this electromagnet 231.242 of this armature plates are arranged in this holding part 211, and the one of which end is to should quiet contact point 213.And an end of this joint fastener 243 is that the other end that connects this yoke iron slice 241, this joint fastener 243 is to connect this armature plate 241, and an end of this joint fastener 243 forms one and electrically contacts salient point.Thus, this armature plate 241 is to be arranged at swingably in this holding part 211.Wherein, an end of this yoke iron slice 241 is more along stretching out a fixing stitch 2411, and it is to plug and through this bottom base 21.In addition, this joint fastener 243 can be processed any curved shape by impact style, through controlling its bending degree adjusting the spacing between this armature plate 242 and this terminal component 25 when the off state, and makes its spacing can reach 1.5mm or greater than more than the 1.5mm.Wherein, This yoke iron slice 241 can be used to strengthen the suction-combining force of solenoid; Improving the effect road of electromagnet, and this yoke iron slice 241 and this armature plate 242 can constitute the magnetic circuit of sealing, and the magnetic line of force that coil unit 232 is produced is closed in inside; Magnetic energy can be fully utilized, improve the electromagnetism iron unilization.In addition, this yoke iron slice 241 more can extend two to more fixedly stitch 2411 downwards with demand, firmly being inserted on the substrate (figure do not show), and improves conductive cross-sectional area.

25 of this terminal components are a L type, and the one of which end forms an electrical contacts 251, make an end then form a terminal pin 252.Wherein, this terminal component 25 is to shape that should slot 212 and be inserted in the slot 212.In the present embodiment, this terminal pin 252 is made up of two leading-out terminals, so not as limit, can also be made up of single or a plurality of leading-out terminal.When fixing this miniaturized relays 2, can this miniaturized relays 2 firmly be arranged on the substrate (figure does not show) through this positive pin 233, this negative pin 234, these fixing five pins such as two-terminal of stitch 2411 and this terminal pin 252.

Please consult in the lump with reference to Fig. 5 and Fig. 6, it is the utility model miniaturized relays preferred embodiment first illustrative view and second illustrative view again.When this miniaturized relays 2 not during start, this joint fastener 243 drives and makes it electrically contact salient point and this fixed contact contact pin 213 is inconsistent owing to receiving its elasticity tension.

When these miniaturized relays 2 runnings; Through being energized to this positive pin 233 and should bearing pin 234; The feasible coil electricity that electrically connects this positive pin 233 and this negative pin 234; Be coated on this coil unit 232 inboard electromagnet and produce electromagnetic induction and produce magnetic and make, make this joint fastener 243 moved towards this electrical contacts by the magnetic of this electromagnet 231, and make the salient point that electrically contacts of this joint fastener 243 contact with terminal component 25 and electrically connect; And can import little electric current and drive the mode of another high-current circuit, as a kind of circuit safety switch.

When cut-out aligns the power supply supply of pin 233 and negative pin 234; Then this coil unit 232 returns back to not "on" position; This electromagnet 231 thereby forfeiture magnetic; This armature plate 242 and this joint fastener 243 thereby do not receive the attraction of this electromagnet 231 and reset no longer contact the salient point that electrically contacts of this joint fastener 243 with this electrical contacts 251 of this terminal component 25, make the electronic loops that electrically connect with this terminal component 25 be off state; And after this joint fastener 243 resetted, it electrically contacts salient point was to contact with this fixed contact contact pin 213.

In sum, the utility model miniaturized relays, its effect are to make this top base and this bottom base one-body molded; Miniaturized relays compared to prior art; Can reduce built-up time and cost, and can be with the overall volume miniaturization, more can the expanding application scope.

The above; Be merely the preferred embodiment of the utility model; Be not the scope of implementing in order to qualification the utility model, the equalization of under spirit that does not break away from the utility model and scope, being done changes and modifies, and all should be covered by in the claim of the utility model.
