Abstract
The utility model relates to a large power electromagnetic relay, which consists of an electromagnetic system, a wiring system and a coil curl frame fixing the electromagnetic system and the wiring system, a base and an encloser, the electromagnetic system consists of a ferrite core, a coil curl, a yoke, an armature, a contact reed, a normally open contact, a normally closed contact and a down-lead sheet which is an inserting type down-lead sheet and whose one end is embedded in a groove of the coil curl frame, and the down-lead sheet is fixed by the base. The large power electromagnetic relay has the following advantages: the large power electromagnetic relay adopts the inserting type down-lead sheet fixed by the coil curl frame and the base, the design is reasonable, the fixing effect is good, the loose inserting and drawing phenomenon of an extraction sheet is solved during the installed process, larger electric current can pass through, thus the large power electromagnetic relay has advantages of convenient installation, big contacting pressure of the contact, safe and stable operation, long service life, strong magnetic force and can be used for high-current control occasion. The inserting type down-lead sheet is adopts and can be provided with a circuit plate installing mode, inserting type mode, etc. The armature is connected to the yoke by the reed to obtain a favorable antihunt action.
Description
Technical field
The utility model relates to a kind of relay, particularly a kind of high-power magnetic relay.
Background technology
Relay is a kind of electronic control device; it has control system and Be Controlled system; usually be applied in the automatic control circuit; it is actually a kind of " automatic switch " that removes to control big electric current with less current, so play effects such as automatic adjusting, safeguard protection, change-over circuit in circuit.
Electromagnetic system and wiring system and the bobbin of fixing these electromagnetic systems and wiring system, pedestal and case that existing electromagnetic relay is made up of iron core, coil, yoke, armature, contact reed, normally opened contact and normally-closed contact, lead wire etc. are formed, and existing bobbin all is connected by injection moulding with the lead wire of coil.Because coil and lead wire adopt the method for injection moulding, so lead wire can't do greatly, and the electric current that causes relay to pass through is also limited, can not be used for the occasion of big electric current, and because lead wire often plugs meeting becomes flexible, causes loose contact.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned defective of prior art and a kind of high-power magnetic relay is provided, and makes it can be by big electric current, and contact is good.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
High-power magnetic relay, form by electromagnetic system and wiring system and the bobbin of fixing these electromagnetic systems and wiring system, pedestal and case that iron core, coil, yoke, armature, contact reed, normally opened contact and normally-closed contact, lead wire etc. are formed, described lead wire is the plug-in type lead wire, the one end is embedded in the groove of bobbin, and is fixed by pedestal.
Above-mentioned armature is connected with reed with yoke.
Compared with prior art, advantage of the present utility model is: adopt the plug-in type lead wire, fix by bobbin, pedestal, reasonable in design, good fixing effect has solved the loosening phenomenon of lead-out tablet plug in inserting installation process, and can be by big electric current, therefore easy for installation, the contact contact pressure is big, use is reliable and stable, the life-span is long, magnetic force is big, can be used for big Current Control occasion.Adopt the plug-in type lead wire, modes such as wiring board installation, plug-in type installation can be arranged.Armature adopts reed to be connected with yoke, and good antihunt action is arranged.

Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
As shown in Figure 1, high-power magnetic relay, by case 14, main body 15 and pedestal 16 are formed, main body 15 is seen Fig. 2, Fig. 3, the last quiet group of being made up of fixed contact 1 and last quiet contact chip 2 that contacts reaches the following group of being made up of fixed contact 3 and following quiet contact chip 4 that contacts, riveting is at two grooves 61 up and down of bobbin 6 securely, on 62, the moving contacting plate 10 that drives contact point 9 is fixed with two projections, 111 riveted joints of armature 11 by two circular holes on it 101, two circular holes 102 of the other end of moving contacting plate 10 are fixing with two projections of yoke 8 one sides 81, bobbin 6 is crossed and yoke 8 rivetings from inter-burst by iron core 5, coil 7 on the intermediate sleeve, bobbin about in the of 6 two side faces establish two grooves, two lead wire 13 1 ends embed in the groove of bobbins 6, the other end embeds in the hole of pedestal 16, firm anchor leg sheet 13, cover is gone up shell 14 then.
Moving contact lead-out tablet 12 1 ends are fixed on the projection 82 of yoke 8 by the hole on it, and the other end passes pedestal 16 and fixes.
The operation principle of relay for knowing, is no longer narrated at this.
