Description

High voltage direct current relay multiconductor structure

Technical field

The utility model discloses a kind of high voltage direct current relay multiconductor structure, divides by International Patent Classification (IPC) (IPC) Belong to high voltage direct current relay manufacturing technology field.

Background technique

Existing high-voltage relay generally only has an electromagnetic coil, a pair of dynamic and static contact of control, if switching When the high voltage load of 200Vd.c. or more, since voltage is too high, cannot reliable current interruption, be easy to cause pitting of contact, or even go out Dead failure is glued in existing contact, is not able to satisfy the requirement that user loads high voltage.

Summary of the invention

In view of the deficiencies of the prior art, the utility model provides a kind of high voltage direct current relay multiconductor structure, realizes Multiconductor current interruption has many advantages, such as structurally reasonable, safe and reliable.

In order to achieve the above objectives, the utility model is achieved through the following technical solutions:

A kind of high voltage direct current relay multiconductor structure, including shell, shell is interior to be equipped with the first energized relay circuit and second Energized relay circuit, each energized relay circuit control a contact point unit and switch on and off, and two contact point units are distributed side by side, each contact Unit includes two groups of dynamic and static contacts, and conducting of connecting between dynamic and static contact, two energized relay circuits control four groups of dynamic and static contacts and formed Multiconductor divides arc structure.

Further, on dynamic spring, dynamic spring connect to form the dynamic touching of attaching type with armature for the movable contact setting of every group of dynamic and static contact Piece, movable contact spring are externally provided with limit film to control the outward angle of movable contact spring, and movable contact spring and plane where limit film are perpendicular Relationship, limit film are fixedly installed and are located on the pedestal of shell.

Further, it is resisted against on yoke at the top of armature, armature top forms hook one tension spring of connection, the connection of the tension spring other end The hook of yoke distal end, armature realize that dynamic and static point switches on and off by corresponding to energized relay circuit control.

Further, the first energized relay circuit and the second energized relay circuit include an electromagnetic coil, and electromagnetic coil is mounted on On the intracorporal coil holder of shell, two energized relay circuits by left and right weld tabs it is in parallel after be electrically connected with two coil pin, coil pin is to shell Relay inserted terminal is extended to form in vitro.

Further, in quiet spring foot, the pedestal formation that quiet spring foot passes through shell is drawn for the stationary contact setting in outside in contact point unit Foot, the stationary contact on the inside of contact point unit are arranged in intermediate conductive sheet, and intermediate conductive sheet connects the quiet of the inside of another contact point unit Contact forms dynamic and static contact series structure.

The utility model is controlled four groups of dynamic and static contacts respectively and is switched on and off by two group relay magnetic circuits, move, It connects and is connected between stationary contact, realize that multiconductor divides arc, have many advantages, such as structurally reasonable, safe and reliable.
