Description
Technical field
The utility model relates to a kind of relay, especially relates to a kind of small high-power relay.
Background technology
Existing small high-power relay is mainly used in occasions such as household electrical appliance, automated system, electronic equipment, instrument and meter, communication device and remote control, it had both required the volume of relay less, require creepage distance big as far as possible again, withstand voltage high as far as possible between contact and coil.A kind of small-sized high-power sensitive-type direct current electromagnetic relay of Very Low Clearance is disclosed as No. 01220748.9 utility model patent that on January 16th, 2002, bulletin was authorized, mainly form by contact system, magnetic circuit system, base and shell, contact system comprises static contact spring piece, U-shaped movable contact spring, and by in the insertion of the guide groove on the base base, the U-shaped press-bending position of movable contact spring is inserted the base guide groove and is fixed.The relay height of this structure is lower, and creepage distance is bigger, withstand voltage higher between contact and coil.But analyze this kind structure relay we can find, under the definite situation in pin position, the requirement of contact system process Installation for convenience, expose in the hole of the base that reed need must be passed, and this makes the degree of depth that contains the cavity of magnetic circuit system on the base reduce relatively, under the situation that rated voltage is fixed, to cause the length of the bobbin of magnetic circuit system to reduce, and the diameter of coil increases, under the constant situation of overall volume, the thickness that contains the cavity of magnetic circuit system on the base also can corresponding attenuation, and its technique effect is exactly to have caused the minimizing of creepage distance and the withstand voltage reduction between contact and coil; In addition, in the installation process of product, the installation of contact system and magnetic circuit system is all cumbersome, operating efficiency is relatively low, and the groove that the coil lead sheet is set also needs after magnetic circuit system installs with corresponding encapsulant sealing, misoperation, encapsulant can leak the inside that enters relay.
The utility model content
Technical problem to be solved in the utility model is to provide a kind of creepage distance bigger at above-mentioned prior art present situation, and withstand voltage higher between contact and coil installed also convenient small high-power relay.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of small high-power relay, comprise base, contact system, magnetic circuit system and case, described contact system comprises moving contacting plate, often open quiet contact chip and normally closed quiet contact chip, be correspondingly provided with the movable contact spring jack on the described base, often open static contact jack and normally closed static contact jack, described magnetic circuit system comprises coil, lead wire, unshakable in one's determination, yoke and armature, described magnetic circuit system is provided with an insulating cover, the other contact groove that extends along the upper bottom surface of described base that is provided with of described normally closed static contact jack, the bottom of described normally closed quiet contact chip is provided with kink, described kink embeds in the described contact groove, described insulating cover covers and is arranged on the top of described normally closed static contact jack and described contact groove and is connected cooperation with described base, described base is provided with the lead wire jack, and described lead wire is inserted in the described lead wire jack.
Be provided with insulating barrier between described contact system and the described magnetic circuit system.
Described contact system can comprise one group of transfer contact.
Described contact system also can comprise two groups of transfer contacts, can be provided with supplementary insulation dividing plate vertical with described insulating barrier and that one is connected two groups of transfer contacts.
Described insulating cover can be connected on the described base by buckle, also can be fixedly connected on by other connected mode on the described base.
Compared with prior art, advantage of the present utility model is independently insulating cover that the cavity that contains magnetic circuit system on the base of the prior art is arranged to separate with base, and the contact groove that embeds of the kink that the bottom that can make normally closed quiet contact chip is set on base, insulating cover just can cover the top that is arranged on normally closed static contact jack and contact groove, this structure increases the degree of depth of insulating cover internal cavity, under the constant situation of coil resistance, because the corresponding increase of length of the bobbin of magnetic circuit system, the number of ampere turns of winding is increased, and the diameter of winding reduces, thereby increased the heat-dissipating space around the coil, under the constant situation of overall volume, the thickness of all right corresponding increase insulating cover, its technique effect is exactly to have increased creepage distance effectively, and has improved withstand voltage between contact and coil greatly, learns after measuring, withstand voltage between contact and coil can be stable reach more than the 5000VAC, and the reliability under this withstand voltage situation improves greatly; This structure is installed together after contact system and magnetic circuit system can being assembled respectively in installation process again, has simplified mounting process, has improved operating efficiency; Can also avoid encapsulant to leak the generation of the situation of the inside that enters relay and substitute original lead-in wire film trap with the lead wire jack; In that being set between contact system and the magnetic circuit system, insulating barrier can further improve withstand voltage between contact and coil
