Abstract

The utility model discloses a relay. The relay comprises iron cores, contact reeds, lower ends of the iron cores are provided with springs, one ends of the springs are fixed on the iron cores, the other ends of the springs are connected with insulating washers, and the contact reeds are fixedly arranged at outer sides of the insulating washers. According to the relay, the iron cores and the contact reeds of the relay can move relatively, when a relay coil is powered on, the iron cores move upwards, contacts on the contact reeds are in contact with wiring pins, and since the springs are arranged between the contact reeds and the iron cores, the contact reeds are allowed to automatically adjust contact angles of the contacts, thereby preventing reduced life of the relay due to incorrect contact positions.

Description

A kind of relay

Technical field

The utility model belongs to electronic control device, especially a kind of relay.

Background technology

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 utility model is not enough for prior art, and a kind of relay is provided, and 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 utility model 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 utility model compared with prior art, have following beneficial effect: the utility model is so that the iron core of relay and contact reed can relative motions, 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.

Description of drawings

Fig. 1 is the structural representation of the utility model embodiment.

Fig. 2 is the explosive view of the relay of use the utility model embodiment.

Embodiment

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 1 to Fig. 2, 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 utility model 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.
