Abstract
The utility model provides a direct current arc extinguishing switch relay mainly including lower casing, go up casing, electromagnetic drive coil, contact bridge holder, U -shaped magnet and big contact. Its characteristic: direct current arc extinguishing switch relay's lower casing, last casing and contact bridge holder adopt the disposable injection moulding of plastics raw materials, drive the contact bridge through contact bridge holder down at magnetic force and contact with contact greatly, break away from through anti - spring force. At a side -mounting U -shaped magnet of big contact, make it in the arc extinguishing magnetic field of contact bridge with the work area formation enclose of big contact. Extrusion sealing rubber circle reaches sealed effect, paints sealed glue or reuse ultrasonic welding machine fastened by welding. Because adopt above -mentioned design, the magnet is blown out the electric arc performance and is obviously improved, the magnet has apparent radiating effect to arc extinguishing area temperature greatly, make electric arc to destroying of contact control, make the life -span of product obviously improve. The wide application can further get in electric automobile engineering electric power system.
Description
Technical field
The present invention relates to field of electrical components, particularly relate to a kind of direct current arc-suppressing switch relay.
Background technology
At present, along with growth in the living standard, electrical equipment is used widely in daily life, and how better the break-make problem of thing followed control apparatus about, it is also proposed higher requirement; Especially in the application aspect of the electric automobile of automobile industry, when use direct current by big current processed, inner generation arc phenomenon, the useful life of serious curtailment conventional DC relay.Therefore, how to use the impact reducing electric arc in direct current relay, extending the useful life of direct current relay, become urgent need to solve the problem in the industry.
Summary of the invention
The object of this invention is to provide a kind of direct current arc-suppressing switch relay.
In order to achieve the above object, the present invention adopts following technical pattern: the lower house of direct current arc-suppressing switch relay, upper shell and contact bridge retainer adopt plastic raw materials once injection moulding; Its feature: direct current arc-suppressing switch relay mainly comprises lower house, upper shell, electromagnetic drive coil, contact bridge retainer, U-shaped magnet and big contact; Electromagnetic drive coil is fixed on inside upper shell, magnetic force iron core and contact bridge retainer integral piece are equipped with in inner side, contact bridge is fixed on inside contact bridge retainer by upper spring, and lower spring is arranged on contact bridge retainer lower end, big contact is fixed in lower house when lower house injection molding, U-shaped magnet is fixed on outside the working region of big contact, and lower house and upper shell are the mounting structure up and down linked together by screw.Magnetic force iron core and contact bridge retainer are processed into one when injection molding as mold insert, also can install or paste integral; Electromagnetic drive coil produces magnetic field after obtaining operating current, and magnetic force iron core, under the effect in this magnetic field, produces the action to the motion of big contact direction; Contact bridge retainer, under the effect of magnetic force iron core, drive contact bridge to contact with big contact, thus realizing circuit is communicated with; Magnetic field dissipate after electromagnetic drive coil loses the job electric current, contact bridge retainer, under the bounce effect of spring, force to drive contact bridge and big contact to depart from, thus realizing circuit disconnects; In the outside of big contact, U-shaped magnet is installed, makes it form the arc extinguishing magnetic field of enclosed in contact bridge and the working region of big contact, also dispelled the heat by U-shaped magnet while of making the electric arc produced during work obtain blowing-out fast; The encapsulation process of lower house and upper shell, is have installing hole everywhere to install screw by upper shell lower house is connected with upper shell, and reaches sealing effectiveness by crush seal rubber ring, or use ultrasonic welding machine reinforcement of weld again; Being provided with at lower house place takes out after straight empty bar takes out straight sky, fills protective gas, increases electric arc and blow out effect, for aesthetic can be added a cover.
The present invention compared to existing technology tool has the following advantages: magnet of the present invention is blown out arc performance and significantly improved, magnet has remarkable radiating effect to arc extinguishing regional temperature greatly, make electric arc to contact destroy to obtain control, make the life-span of direct current arc-suppressing switch relay improve more than 20 times.Product natural beauty, simplicity generosity, safe and reliable and specification, easy for installation, extensive use can be obtained further in electric vehicle engineering electric power system.
