Abstract

Disclosed is a high sensitive minitype relay composed of a base on which a movable reed with a movable contact point and a static reed with a static contact point, a coil former winded by an enameled wire and with a terminal pin, an armature connected by a yoke iron and a pushing push rod which are integrated by an iron core and a circlip, and the integration installed on the base and in a housing. Both ends of the circlip are pressed on the yoke iron and the armature to form integration; the periphery of the end of the armature is connected with one end of the pushing rod. The key pushing rod structure of the high sensitive minitype relay has simple shape, easy manufacture and processing, big contact area of the armature and the pushing rod, good cooperation; the edge of the pushing rod with a position head functions to push and position; when power supply powers on, the armature quickly and stably pushes the pushing rod to move, and thus the utility model has high fidelity, safety and reliability.

Description

The high sensitivity miniature relay

Technical field

The utility model relates to a kind of relay, can directly be weldingly fixed on the printed substrate, and extensively in automated system, the high sensitivity miniature relay that uses in electronics, communication, remote control and the Medical Devices etc.

Background technology

Flourish with scientific and technological cause, electronic product is miniaturization day by day, especially the relay to using on the printed substrate, more require handsome first miniaturization, this has just caused the relay installing space as far as possible little, but dielectric withstanding voltage intensity can not reduce, and every performance index will reach standard, wants safety, reliable and use.

The patent No. 01230087.X Very Low Clearance small-sized high-power electromagnetic relay of divider wall " band ", though a kind of dielectric strength, miniaturized relays that compressive resistance is high also are provided, its structure is complicated, fabrication and processing, trouble is installed.

Summary of the invention

Technical problem to be solved in the utility model is: a kind of high sensitivity miniature relay is provided, and its simple in structure, easy assembling, and dielectric withstanding voltage intensity height, working stability, sensitivity is higher, uses safer, reliable.

The technical scheme in the invention for solving the above technical problem is: the high sensitivity miniature relay, static contact spring piece by the movable contact spring that drives the contact, band fixed contact is fixed on the pedestal, be wound with enamelled wire, have the bobbin of terminal pin, by unshakable in one's determination, jump ring yoke being reached the armature that is connected with push rod connects in aggregates, be installed on the pedestal, form in the shell, the two ends riveting of described jump ring is on yoke, armature, connect in aggregatesly, the periphery of described armature end is connected with an end of push rod.

Compared with prior art, advantage of the present utility model is: the base construction of this relay, simple shape, make the unidirectional opening that bobbin is installed, the cavity that sealing is isolated become big, cavity is isolated with the dynamic and static reed of the big electric current of output break-make, increase creepage, electrical distance, improved insulation property.Shape and structure main, the vital part push rod wherein is also very simple, easy fabrication and processing, the armature end periphery all inserts in the little frame of push rod one end, make the contact area of armature and push rod big, work good, the push rod lower surface has the inclined-plane that cooperates with base top surface in addition, makes moving resistance little, therefore as long as energized, armature can steadily promote push rod rapidly and moves once moving, dynamic and static contact is contacted, thereby reach highly sensitive requirement.And edge one end and the centre in addition of push rod have one to promote point and anchor point respectively, and interfix point contacts with movable contact spring all the time, have removed the location and have also played the promotion double action, and the sensitivity that has increased it again is also safe and reliable.

Embodiment

Below in conjunction with accompanying drawing embodiment of the present utility model is further described:

Pedestal has convex tendon on 2 bottom surfaces, on the termination guiding groove hole is arranged, and the centre has the sealing of a single face opening to isolate cavity, and there is the slideway of symmetry inwall lower end, cavity both sides, and the platform that exceeds is arranged on the cavity end face.

Push rod 9 is a shaped as frame, and lower surface both sides and pedestal 2 cooperation places are for reducing the inclined-plane of resistance, and an end has a little sash 15, on the two ends of inwall the convex surface that exceeds is arranged on one side in the lattice, it is tightr that it is cooperated with armature, on the centre and an edge of push rod 9 other end margins, positioning head 16, pusher head 17 arranged respectively.

Riveting is distinguished on armature 11 and yoke 12 in jump ring 13 two ends, connects to be integral.Iron core 10 passes and is wound with the bobbin 3 that enamelled wire 4 has terminal pin 14, be riveted on and form the magnetic circuit part on the yoke 12, and magnetic circuit partly is installed in pedestal single face opening, in the cavity that sealing is isolated, isolate with output, and the movable contact spring 7 of drive contact 8, the output pin of the static contact spring piece 5 of band fixed contact 6, insert in the guiding groove hole on pedestal 2 one terminations fixing, push rod 9 is placed on pedestal 2 tops, the little sash 15 of one end is enclosed within on armature 11 peripheries, and the through hole that the pusher head 17 that other holds is passed on the movable contact spring 7 is connected with movable contact spring 7, and positioning head 16 contacts with movable contact spring 7 end faces, cover shell 1, and plastic packaging becomes whole relay.

During use, utilize terminal pin 14 and movable contact spring 7 on it, static contact spring piece 5 is weldingly fixed on relay on the wiring board, when the energising of terminal pin 14 two ends of coil produces magnetic field, unshakable in one's determination 10 inhale moving armature 11 moves near unshakable in one's determination, move right thereby drive the push rod 9 that links together with armature 11, promote movable contact spring 7 by the pusher head on the push rod 9 17 and move right, the moving contact 8 on it is contacted with fixed contact 6, output is connected, and controlled the break-make of output by the break-make of input power supply.
