Abstract

The utility model relates to a super small-sized high-power relay, which is particularly suitable for an automobile, and the super small-sized high-power relay can replace the original relay with large volume. The super small-sized high-power relay can cause yoke iron and an armature to be connected into integration through frameworks of an upper and a lower contact sheets which are connected with an iron core, a coil, and a leading-wire sheet and are provided with static contacts, and through a movable contact sheet which can drive the contacts and a middle contact sheet. However, the movable contact sheet is provided with a bending tongue sheet which is covered on the yoke iron and the armature; the upper layers of the frameworks are provided with grooves which are mutually vertical; the lower layers are provided with a jack and an inserted groove, and the lower contact sheet is provided with a bending portion which is matched with horizontal grooves and the jack. Compared with products with the same type, volume of the super small-sized high-power relay is reduced more than one time; load of the contacts is increased by 1/3, and shock resistance is good.

Description

Superminiature high-power relay

The utility model relates to a kind of miniature electro-magnetic relay, suitable especially being used on the automobile, replace original 4117 type relays and automobile accessories to use, also can be used on the Superminiature high-power relay that uses on household electrical appliance, automated system, electronic equipment, instrument, instrument, communication, the beepbox.

Continuous development along with electronics industry, require that electronic product is highly sensitive, good reliability and tend to miniaturization, following one by one is that requirement parts matching used with it also require to be tending towards miniaturization, and the existing 4117 type relays that use, volume is more greatly in 18 * 16.4 * 20 scopes.

The purpose of this utility model is to provide a kind of Superminiature high-power relay, and it is highly sensitive, good reliability, and volume is little, contact load is big, and have shockproof function.

The utility model is achieved in that Superminiature high-power relay is linked into an integrated entity yoke, armature by the skeleton of the upper and lower contact that is connected with iron core, coil, lead wire, band fixed contact and the movable contact spring that drives contact, middle contact, be installed in case, the pedestal and form, and the tongue piece that bends is arranged on the movable contact spring, be coated on yoke, the armature, there is vertical each other groove on the skeleton upper strata, there are jack and slot in lower floor, on the following contact bending that cooperates with skeleton groove, jack is arranged.

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

The lead wire (12) at coil (6) two ends, fixed contact (2), moving contact (3), (5), armature (7) unshakable in one's determination, yoke (8), middle contact (11), the case (1) gone up on the contact (14) are all same as the prior art, do not describe in detail.

One end riveted and fixed moving contact (3) of movable contact spring (9), contact (11) during the end welding is fixed in addition, central closing has a tongue piece (15) and bends into 90 °.

Skeleton (4) is selected the high material of dielectric strength for use, and the cross section is worker's shape, and there is the boss that exceeds on the both sides of one end on the upper strata, vertical groove is arranged on the lateral edges of one boss, on the positive edge of two boss horizontal groove is arranged, on the edge of lower floor a through hole is arranged, there are two slots at the edge in addition of symmetry.

Pedestal (10) is a box-like, and bottom outer surface has outstanding sole piece, and there are five lead-out wire through holes at the edge, and inner surface has positioning bar.

The lower limb of following contact (13) upper end have one with the parallel bending inserting hook of 90 ° of bending edges of upper surface, the lower end is elongated pin.

Yoke (8), coil (6), (5) unshakable in one's determination all are fixed on the skeleton (4), the movable contact spring (9) of contact in the band (11), moving contact (3) is riveted into one armature (7), yoke (8), and the tongue piece (15) that bends on the movable contact spring (9) is coated on the edge of armature (7), yoke (8).Two lead wire (12) are inserted respectively in two slots of skeleton (4) lower edge, the last contact (14) of band fixed contact (2) is vertically by in the jack on groove insertion skeleton (4) lower edge of lateral edges, upper and lower two parallel bendings on the following contact (13) of band fixed contact (2) are inserted respectively in the horizontal groove and jack of the upper and lower layer of skeleton (4), put into case (1) again, cover pedestal (10), relay is made in sealing again.

During use, feed electric current, coil (6), (5) adhesive armature (7) unshakable in one's determination from lead wire (12), open normally-closed contact, the conducting normally opened contact is finished the break-make of change-over circuit and is controlled automatically.

The utility model is compared with prior art: coating armature, yoke because the tongue piece that bends is arranged on the movable contact spring The edge makes it shockproof, and the protecting against shock performance is good, lower contact is to insert skeleton from horizontal direction, makes like this skeleton More compact structure, so volume can dwindle. Pedestal is box-like in addition, makes the position of lead wire compacter, this Sample also makes the volume of skeleton reduce, and this relay volume is 15.7 * 12.3 * 14, reduce volume more than a times ( Be compared with existing technology), the structure by skeleton, pedestal has guaranteed location and air gap simultaneously, adds improvement The material of contact, contact makes the load of contact improve 1/3.
