Abstract
The utility model relates to an electromagnetic relay which includes a contact system, a magnetic circuit system, a base and a cover casing. The contact system and the magnetic circuit system which are installed on the base are arranged in the cover casing. The contact system includes a moving contact piece and a static contact piece. The magnetic circuit system includes a coil, a reed, an iron core, a yoke and a keeper. The electromagnetic relay is characterized in that the periphery of the coil is covered with an insulation cover which is isolated from the yoke, the keeper and the reed. The open end of the insulation cover is jammed on the base. An insulation protective sleeve is arranged on the yoke, corresponding to the assembly position of the insulation cover and the base. The insulation protective sleeve is L shape. The pressure resistance between a contact and the coil is effectively improved to achieve the strengthening requirement of 3750V for the insulation. The creepage distance is also strengthened. The best combination is realized within the limited space without influencing the installation process of the relay.
Description
Technical field
The utility model relates to a kind of electromagnetic relay, and especially a kind of volume is little, the electromagnetic relay of compact conformation.
Background technology
Electromagnetic relay is as electronic control device, mainly comprise the contact system that moving contacting plate and quiet contact chip are formed, the parts such as magnetic circuit system that coil, reed, armature, yoke are formed, will produce galvanomagnetic effect to powering up on the coil, armature will make moving contacting plate and quiet contact chip connect under electromagnetic attracting force.Thus, utilize relay to control high voltage, heavy current, be widely applied to occasions such as household electrical appliances, electronic equipment, instrument and meter, communication device.
Under some occasion, electromagnetic relay has been proposed specific (special) requirements, promptly require the volume of relay little, require creepage distance, electric clearance big as far as possible simultaneously, withstand voltage high as far as possible between contact and coil.Volume means that for a short time the accommodation space in the relay case dwindles, require restriction mutually with relay self assembly technology, and relay is as crucial electric device, the requirement of the insulation property of safety is arranged again, require to reach the withstand voltage demand of 3750V in the occasion of the reinforced insulation in some field, form the contradiction of two kinds of demands like this, restricted the use of electromagnetic relay.
Summary of the invention
Technical problem to be solved in the utility model is at existing above-mentioned present situation, provides a kind of and can satisfy creepage distance and high requirement of withstand voltage, small-sized high-power electromagnetic relay that again can be easy for installation.
The utility model solves the problems of the technologies described above the technical scheme that is adopted: a kind of electromagnetic relay, comprise contact system, magnetic circuit system, pedestal, case, the contact system, the magnetic circuit system that are installed on the pedestal are sleeved in the case, described contact system comprises moving contacting plate, quiet contact chip, described magnetic circuit system comprises coil, reed, iron core, yoke and armature, it is characterized in that, the periphery of described coil covers an insulating cover of isolating with yoke, armature, reed, and the insulating cover opening end snaps fitted on the pedestal.
Assembling place of corresponding insulating cover and pedestal, yoke is provided with insulating sleeve, and insulating sleeve is L-shaped.
External insulating sleeve is that one is injected on the yoke.
Compared with prior art, advantage of the present utility model is to be assembled to the insulating cover on the pedestal, it covers the periphery of coil, isolate with yoke, armature, reed, improved withstand voltage between contact and coil so effectively, reached the requirement of reinforced insulation 3750V, and increased creepage distance, not influencing under the mounting process prerequisite of relay itself, realized best combination.In limited space, in order to reach better withstand voltage insulation effect, assembling place at corresponding insulating cover and pedestal, yoke is provided with insulating sleeve, insulating sleeve is L-shaped, the yoke that guarantees the contact so better and be electrically connected has with it prevented to reduce withstand voltage possibility by the assembling slit of insulating cover and pedestal at the requirement of withstand voltage of corner and coil.
