Description

A kind of plug locking and tripper of monomer

Technical field

The utility model relates to a kind of plug locking and tripper of monomer, plug locking and the tripper of particularly a kind of monomer in embedded power-supply system.

Background technology

At present, various electrical type monomer products carry out the locking and unlocking by locking device in system, thereby realize the hot plug function of monomer, and satisfy requirements such as corresponding vibration and packing.Locking device comparatively commonly used at present is to carry out the fixing of monomer by spring assembly, and spring can be divided into two kinds by the kind difference: stage clip and torsion spring.Adopting stage clip to lock mainly is to utilize the compression spring to produce elastic force bearing pin is pressed in the open slot, thus the locking monomer; When bearing pin put in place, spring discharged the elastic force of compression, thereby can allow the operator feel that monomer puts in place; When release, outwards drag monomer when upwards lifting bearing pin, get final product release.Mainly be to have utilized its twisting resistance when utilizing torsion spring to lock, torsion spring is stressed when the promotion monomer enters, and the operator had obvious sensation after locking put in place; When release, the operator pulls torsion spring, and outwards drags monomer, gets final product release.The locking device that but utilizes spring design is bigger to the design space that system and monomer require, and for the power density height, just can't realize under the narrow and small situation in design space.

There is a kind of device that utilizes the spanner gyration to lock in the market, preferably resolve the problem of monomer locking under the less situation in space, Fig. 1 is existing a kind of locking device, carry out spacing behind the gyration arrival relevant position of this device by spanner 102, feel is bad but there is locking in this wrench device, and whether put in place during locking the accurately defective of perception; And be connected with box system by the riveting rotating shaft 103 of rising, assembly technology requires high, causes spanner 102 to rotate easily to have some setbacks or slack and undisciplined; Finish locking by lock screw 101, the locking of plug and release are all inconvenient, need be by instrument; In addition, wrench body adopts the sheet metal bending, and cost in enormous quantities is higher.

Summary of the invention

The purpose of this utility model is, a kind of plug locking and tripper of monomer is provided, and compared with prior art, it need can not carry out the locking and the release of monomer by instrument, makes the plug locking of monomer accurately firm, more convenient to operate.

For achieving the above object, the utility model provides a kind of plug locking and tripper of monomer, comprise wrench body of deciding screw with lock, the monomer of band lock hole, wrench body is connected mechanically with monomer, when monomer is in the lock state is to insert in the box system, it is characterized in that described wrench body comprises alignment pin, spacing hole, described monomer also comprises the inside convex closure that has elastic arm, and described box system comprises spacing track; Alignment pin and spacing track size, position are corresponding, and in the monomer locking process, alignment pin carries over spacing track and slides, alignment pin and spacing track inscribe during locking, spacing hole and convex closure inscribe;

Further, the mechanical connection manner of wrench body and monomer is by rotating shaft, back-up ring clamping;

Further, when convex closure and spacing hole inscribe, the point of contact is positioned on the spacing hole horizontal diameter;

Further, the shape of spacing track is that straight-line synthetic simulation when inserting box system by alignment pin around the circular motion of rotating shaft and monomer forms;

Further, the lines that increases frictional force is arranged on the lock screw;

Further, wrench body is made by die casting.

The beneficial effects of the utility model are: plug the locking and unlocking of monomer all can be controlled with unlatching by the locking of screw and get final product, and lock function is good, does not need the instrument dismounting, plug brings great convenience to monomer, good hand touch during locking is saved the space, and cost is low.

Embodiment

Be described in detail below in conjunction with 2～6 pairs of monomer plug-in and pull-off devices of the present utility model of accompanying drawing.

Shown in Fig. 2,4, the utility model locking device comprises lock screw 201, lock hole 209, wrench body 202, back-up ring 203, elastic arm 207 and top inside convex closure 208 thereof; Alignment pin 204, rotating shaft location hole 205, spacing hole 206 are arranged on the wrench body 202; Lock screw 201, back-up ring 203 are connected on the wrench body 202, and lock screw 201 is free to rotate.

As shown in Figure 3, limited Bit Track 301 on the box system 601, the rectilinear motion simulation of its shape when to be alignment pin 204 around the circular motion of rotating shaft 501 and monomer 210 insert box system 601 is synthetic, therefore alignment pin 204 can smoothly move along spacing track 301, alignment pin 204 and spacing track 301 inscribes during locking, guarantee firm kayser, not loosening.

As Fig. 2, shown in Figure 3, in locking process, promoting wrench body 202 501 rotates monomer 210 insertion box system 601 around the shaft, alignment pin 204 on the wrench body 202 around the shaft 501 when making circumference and rotate along with monomer 210 has a rectilinear motion to box house, therefore, can be along with spacing track 301 smooth motions, and under the propulsive thrust of spacing track 301 the most at last monomer 210 be pushed in the box system 601.

Convex closure 208 on the elastic arm 207 is corresponding with the spacing hole 206 of wrench body 202, when spacing hole 206 turns over the inside convex closure of elastic arm 207, can hear " snap " locking sound, and hand has obvious sense of touch simultaneously.When complete closure, convex closure 208 and spacing hole 206 inscribes.

Lock screw 201 is got on the bus increases the lines of frictional force, but therefore twill, straight burr or cross cut can directly can finish locking by the hand-screw knob; When release, need can not open lock screw 201 by any instrument yet, rotating spanner main body 202 makes it to produce outside thrust, outwards promotes monomer 210, i.e. release.

Monomer 210 at box system 601 internal locks state regularly as shown in Figure 6.

In addition, above-mentioned wrench body 202 is to adopt the metal crimp foundry goods to constitute, and therefore not only has structure function, and has tangible modeling function.

Said apparatus is not limited to the hot plug monomer, also can be applicable to other monomers.

In sum, the utility model is by the connected mode of lock screw, wrench body and monomer---rotating shaft and back-up ring, casing elastic arm, the improvement of monomer manufacture in addition, make the locking release of monomer in casing plug system accurately quick more, also saved the shared space of locking device, made the manufacturing cost of locking spanner obtain very big reduction simultaneously.

More than be in order to make those of ordinary skills understand the utility model; and to detailed description that the utility model carried out; but can expect; in the scope that does not break away from claim of the present utility model and contained, can also make other variation and modification, these variations and revising all in protection range of the present utility model.
