Abstract

The utility model provides a loop coil fixed briquette, which has simple structure and firm compression joint, can automatically locate and is convenient to use; the briquette is arranged on a loop coil transversely and is provided with a fixing hole in the center, a part where the lower surface of the briquette contacts the upper surface of the loop coil is an arc which corresponds to the arc on the surface of the loop coil, thus a convex-concave clamping structure is formed between the briquette and no relative displacement occurs between the briquette and the loop coil after being pressed tightly; meanwhile, when the briquette is assembled, the loop coil can automatically locate with the arc at the lower surface of the briquette, accelerating assembly speed and improving assembly quality; the briquette has a better force bearing structure and can be formed by pouring plastics, reducing the manufacturing cost.

Description

Annular coil is briquetting fixedly

Technical field:

The utility model relates to fixedly briquetting of a kind of annular coil.

Background technology:

At present, annular coil must be pressed on annular coil on the base with fixing briquetting, fixedly briquetting generally is with high-intensity insulation plate material, annular coil is placed on the base, the briquetting two ends are across on the annular coil, hold-down screw passes the fixing hole on the fixing briquetting, links to each other with base, because the upper surface of annular coil is circular-arc, dull and stereotyped briquetting is pressed thereon, both contact-making surfaces are less, are the line contact in theory, and this crimping mode has two shortcomings, the one, crimping is not firm, be easy to take place relative displacement between the two, the 2nd, when assembling the coil location difficulty, be difficult to accomplish accurately to assemble or keep the dimensional uniformity of assembled product.

Summary of the invention:

The purpose of this utility model be to provide a kind of simple in structure, crimping is firm, automatic location, the fixing briquetting of annular coil easily.

The utility model is achieved in that a kind of fixedly briquetting of annular coil that is used for, briquetting is across being positioned on the annular coil, there is fixing hole at the briquetting center, it is characterized in that: it is that part of that described briquetting lower surface contacts with the annular coil upper surface is circular arc, and described circular arc is corresponding with coil upper surface circular arc.

Described briquetting shape can be similar to the Y type, and two terminations of briquetting extend beyond coil upper surface highest point.

Described briquetting lower surface center can have down to the boss that extends.

Described boss can be the cylinder that extends downwards.

Around the described briquetting upper surface convex barring limit can be arranged, constitute the briquetting reinforcement.

Fixing hole can pass the boss center.

The utility model is because briquetting lower surface and annular coil contact portion are circular arcs, and corresponding with the circular arc of annular coil upper surface, form concavo-convex relative screens structure between briquetting and the annular coil, and the contact of formation face, after compressing, can not produce relative displacement between briquetting and the annular coil; Simultaneously, when briquetting assembled, annular coil can have been accelerated assembling speed automatically along with briquetting lower surface center of arc location, has improved assembly quality; Briquetting itself has load-carrying construction preferably, can use injection mo(u)lding, has reduced manufacturing cost.

Fig. 3 is a upward view of the present utility model.

Embodiment:

Below in conjunction with accompanying drawing the utility model is described in detail: be used for the fixing briquetting 1 of annular coil on the power supply cabinet rectification module, briquetting 1 is across being positioned on the annular coil, there is fixing hole 2 at the briquetting center, hold-down screw passes fixing hole 2 annular coil is crimped on the base, it is that part of that described briquetting lower surface contacts with the annular coil upper surface is circular arc 3, described circular arc 3 is corresponding with annular coil surface circular arc, concave arc and dome arc match, after the crimping relative displacement can not take place, described briquetting 1 shape approximation Y type, two terminations 4 of briquetting extend beyond coil upper surface highest point, guarantee that coil bears vertical compression rather than the outside stress that rises, to the boss 5 that extends, described boss 5 was the cylinders that extend downwards, the annular coil positioning accuracy when having guaranteed crimping better under described briquetting lower surface center had, convex barring limit 6 is arranged around the described briquetting upper surface, constitute the briquetting reinforcement, increase the strength and stiffness of whole briquetting, fixing hole 2 passes the boss center.
