Description
Technical field
The utility model is related to a kind of electromagnetic relays, more particularly to a kind of electromagnetic relay of high-insulativity.
Background technology
Electromagnetic relay generally comprises shell, magnetic circuit part, dynamic spring part, quiet spring part, magnetic circuit part include bobbin,
Enameled wire, iron core, it includes normally opened quiet spring and normally closed quiet spring, bobbin top to move spring part including dynamic spring and armature, quiet spring part
Side is equipped with mounting portion, and quiet spring is partly installed in the mounting portion, which forms a U-shaped accommodating chamber, quiet spring part it is quiet
Contact and the movable contact of dynamic spring are located in the U-shaped accommodating chamber.This electromagnetic relay of the prior art is due to its normally opened quiet spring
Creepage distance between normally closed quiet spring is short, the bad problem of pressure resistance between causing the product electric life later stage contact occur.
Utility model content
The utility model provides a kind of electromagnetic relay of high-insulativity, and which overcome the electromagnetic relays of the prior art
Existing shortcoming.
Technical solution adopted by the utility model to solve its technical problems is：A kind of electromagnetic relay of high-insulativity,
Including shell, magnetic circuit part in the shell, dynamic spring part, quiet spring part be set, magnetic circuit part include bobbin, enameled wire,
Iron core, bobbin top side are equipped with mounting portion, and quiet spring part is set to the mounting portion, which, which has, is used for the quiet spring of grafting
Partial pin and two first wall bodies being oppositely arranged, and between two first wall bodies and two second walls that are oppositely arranged
Body；Quiet spring part includes the normally opened quiet spring being distributed up and down and normally closed quiet spring；In the contact of quiet spring part and respectively on each second wall body
Position between first wall body is respectively equipped with barricade, which is less than the first wall body.
Further, the position on each second wall body between the contact and the barricade of quiet spring part is respectively equipped with first
Groove, the position on each second wall body between the barricade and the first wall body are respectively equipped with the second groove.
Further, the barricade between the two with this adjoins respectively for first groove and the second groove.
Further, dowel is equipped between two barricades being oppositely arranged on described two second wall bodies.
Compared to the prior art, the utility model has the advantages that：
The setting of the barricade can increase effective creepage distance between normally opened quiet spring and normally closed quiet spring, improve product electricity
Pressure-resistant performance between later stage in service life contact.The setting of first groove and the second groove, coordinates the barricade, can be further
Increase effective creepage distance between normally opened quiet spring and normally closed quiet spring, further increases the pressure resistance between product electric life later stage contact
Performance.
The utility model is described in further detail with reference to the accompanying drawings and embodiments；But the utility model is a kind of high
The electromagnetic relay of insulating properties is not limited to embodiment.

Fig. 5 is the enlarged diagram of part A in Fig. 4.
Specific implementation mode
Embodiment refers to shown in Fig. 1-Fig. 5, a kind of electromagnetic relay of high-insulativity of the utility model, including outer
Shell, is arranged magnetic circuit part in the shell, dynamic spring part, quiet spring part, magnetic circuit part include bobbin 1, enameled wire, iron core,
Yoke, enameled wire are wrapped on bobbin 1, and iron core is plugged in bobbin 1, and yoke is arranged in iron core bottom end；Dynamic spring part packet
Spring and armature are included, it is in L-shaped to move spring, and dynamic spring is fixed with yoke on one side, and another side is fixed with armature, and armature coordinates in iron core
Top.1 top side of bobbin is equipped with mounting portion 11, and quiet spring part is set to the mounting portion 11, which, which has, is used for
The pin of the quiet spring part of grafting and two first wall bodies 111 being oppositely arranged, and set between two first wall bodies 111 and relatively
Two second wall bodies 112 set；Quiet spring part includes the normally opened quiet spring 2 being distributed up and down and normally closed quiet spring 3；On each second wall body 112
Position between the contact and each first wall body 111 of quiet spring part is respectively equipped with barricade 113, which is less than the first wall
Body 111.
In the present embodiment, the position difference on each second wall body 112 between the contact and the barricade 113 of quiet spring part
Equipped with the first groove 114, the position on each second wall body 112 between the barricade 113 and the first wall body 111 is respectively equipped with
Two grooves 115, and the barricade 113 between the two with this adjoins respectively for the first groove 114 and the second groove 115.
In the present embodiment, it is equipped with dowel 116 between two barricades 113 being oppositely arranged on described two second wall bodies 112, makes
Two opposite barricades 113 are integrally connected on two second wall bodies 112, and improve the intensity of barricade 113.
A kind of electromagnetic relay of high-insulativity of the utility model, barricade 113 coordinate the first groove 114 and second recessed
