Abstract
The invention discloses a relay which comprises an iron core and a contact spring. A spring is arranged at a lower end of the iron core, one end of the spring is fixed on the iron core, the other end of the spring is connected with an insulating washer, and the contact spring is fixedly arranged on an outer side of the insulating washer. The iron core and the contact spring can relatively move, when a relay coil is electrified, the iron core moves upwards contacts on the contact spring to be contacted with wiring pins, and the spring is arranged between the contact spring and the iron core, so that the contact spring can automatically adjust the contacting angle of the contacts, and reduction of the service life of the relay caused by the contacts in incorrect place is avoided.
Description
Technical field
The invention belongs to electronic control device, especially a kind of relay.
Background technology
[0002] relay is a kind of electronic control device, usually is applied to play the effects such as automatic adjusting, safeguard protection and change-over circuit in the automatic control circuit in circuit.Existing relay mainly comprises coil, iron core, contact reed, spring, coil housing, insulating washer, wiring pins etc., the iron core of existing relay are to be fixedly connected with contact reed, because the product error can't guarantee that it is vertical the connection that iron core and contact reed are fixedly connected with, therefore be fixedly connected with contact and the wiring pin contact position that usually can not guarantee contact reed correct, cause reduce the useful life of relay.
Summary of the invention
The present invention is directed to the prior art deficiency, a kind of relay is provided, this relay can so that the contact position of contact reed and wiring pin is correct, prolong the useful life of relay.
In order to solve the problems of the technologies described above, the present invention is solved by following technical proposals: a kind of relay, comprise iron core, contact reed, described iron core lower end is provided with spring, described spring one end is fixed on the iron core, and the described spring other end is connected with insulating washer, and described contact reed is fixedly installed on the insulating washer outside.
In the technique scheme, preferred, described spring and described iron core adopt spring collar to fix, and adopt the fixing not only convenient fixing of spring collar but also low price easy for installation.
In the technique scheme, optional, described spring be fixed on the iron core an end connect insulating washer one end above.
In the technique scheme, optional, described spring be fixed on the iron core an end connect insulating washer one end below.
The present invention compared with prior art, has following beneficial effect: the invention enables the iron core of relay and the contact reed can relative motion, when relay coil is switched on, the contact that iron core moves upward on the contact reed contacts with wiring pin, owing to being provided with spring between contact reed and the iron core, so that contact reed can be adjusted the contact contact angle automatically, avoided causing relay life to reduce because contact position is not right.

Fig. 2 is the explosive view of the relay of the use embodiment of the invention.
Fig. 3 is that contact reed cooperates schematic diagram with the expression piece.
Fig. 4 is the structural representation in the insulating sleeve.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is described in further detail: referring to Fig. 1 to Fig. 4, a kind of relay, comprise iron core 1, contact reed 2, be provided with two contacts 21 on the described contact reed 2, described iron core 1 lower end is provided with spring 3, described spring 3 one ends are fixed on the iron core 1, described spring 3 other ends are connected with insulating washer 4, described contact reed 2 is fixedly installed on insulating washer 4 outsides, described spring 3 adopts spring collar 5 fixing with described iron core 1, in the present embodiment, described spring 3 be fixed on the iron core 1 an end connect insulating washer 4 one ends below, can certainly described spring 3 be fixed on the iron core 1 an end connect insulating washer 4 one ends above.The two ends of described contact reed 2 are respectively arranged with stay cord 12, one end of described stay cord 12 is provided with mark block 8, the lateral wall of described mark block 8 is coated with two kinds of different colours layers, be provided with insulating sleeve 10 on the casing of relay 9, described mark block 8 is positioned at insulating sleeve 10, offer an inspection hole 101 on the sidewall of insulating sleeve 10, the upper end of described mark block 8 is provided with elastic parts 11, one end of described elastic parts 11 is connected on the mark block 8, after the actuating of relay, stay cord 12 up draws, and after the color of mark block 8 upper ends be cannot see fully, then shows the fully reliable contact of contact reed 2.
The present invention in use, when the coil 6 of relay is switched on, the contact 21 that iron core 1 moves upward on the contact reed 2 contacts with wiring pin 7, owing to being provided with spring between contact reed 2 and the iron core 1, so that contact reed 2 can be adjusted contact 21 contact angles automatically, avoided causing relay life to reduce because 21 positions, contact are not right.
