Abstract

The utility model relates to a structural improvement on an ultrathin bridge rectifier, and provides an ultrathin bridge rectifier capable of preventing plastic-packaged black rubber from reverse package. The ultrathin bridge rectifier comprises a copper baseplate and a package, wherein the copper baseplate is fixedly connected to the back of the package; side bulges are respectively formed on two sides of the lower part of the copper baseplate; a side groove I and a side groove II are respectively formed on the side surfaces of the package and correspond to the side bulges on the two sides; a distance between the side groove I and the side groove II is t; the distance between the outer edges of the two side bulges is h; and t is smaller than h. In the scheme, a top groove is formed at the top of the package and takes a three-point leveling effect together with the two side grooves, so that the copper baseplate is well arranged at the back of the package evenly. The ultrathin bridge rectifier has a simple structure, radically avoids reverse package of black rubber, increases the exposed surface area of the copper product and improves the heat dissipation performance and the electrical property.

Description

Ultra-thin bridge heap

Technical field

The utility model relates to the anti-encapsulate design of ultra-thin bridge heap, relates in particular to the improvement of ultra-thin bridge pile structure.

Background technology

Ultra-thin bridge heap of the prior art, like Fig. 4, shown in 5, bottom copper coin 10 is designed to rectangle; This product is half pack arrangement, and after plastic packaging pressing mold operation, bottom copper coin 10 will come out at the back side of former packaging body 20 fully; Supply the client to weld use, have certain radiating effect simultaneously.But " encapsulate phenomenon " often appears in the bottom copper coin 10 of this technical scheme.The reason that the encapsulate phenomenon occurs is as shown in Figure 7, and bottom copper coin 10 has only the 1/5 top place and the crimping of encapsulating mould, and the lower part of bottom copper coin 10 all is in the chamber of encapsulating mould under no restrained condition.The one, the strain of himself, the base may break away from base plate; The 2nd, when injecting glue, sizing material also can pierce the slit, base under pressure, makes the lower part of bottom copper coin 10 encapsulate part 4 occur.Promptly there is the black glue anti-package of plastic packaging to wrap.Like this, can cause to increase the operation of brushing surperficial rubber (encapsulate part 4) together behind the plastic packaging, increase personnel's the amount of labour, cause the waste of water, electricity.

The utility model content

The utility model has proposed a kind of ultra-thin bridge heap that prevents that the black glue anti-package of plastic packaging from wrapping up in to above problem.

The technical scheme that the utility model adopts is: comprise copper soleplate and packaging body, said copper soleplate is fixedly connected on the back side of said packaging body; Both sides in said copper soleplate bottom are respectively equipped with lateral process, and the lateral process of corresponding said both sides, the side of said packaging body is respectively equipped with side channel one and side channel two.

Distance between said side channel one and side channel two bottom lands is t, and the outward flange mutual spacing of said two lateral processes is from being h, described t < h.

The width of said packaging body is H, described h≤H.

The crown center position of said packaging body is provided with inverted draw cut; Said inverted draw cut and said side channel one form an isosceles triangle with side channel two.

The utility model is the both sides with the copper soleplate bottom, increases by two lateral processes; Packaging body is provided with 2 pressure surface grooves (being side channel one, side channel two), when plastic packaging, behind the mould matched moulds, reserves the position of two side pressure surface grooves, on this two pressure surfaces groove position, can adopt pressure column that the bottom of copper soleplate is closely pressed together on the counterdie plane; Even if the sizing material of big pressure is arranged like this, can not infiltrate from the copper soleplate feather edge yet, thoroughly overcome the encapsulate phenomenon.In addition, this case is provided with inverted draw cut at the top, and forms the effect of 3 pressings between two side channels, makes copper soleplate smooth, docile at the packaging body back side.The utility model is simple in structure, has thoroughly solved black glue anti-package and has wrapped up in phenomenon, has increased the exposed surface area of copper material, has improved heat dispersion and electrical property.

Embodiment

The utility model comprises copper soleplate 1 and packaging body 2 shown in Fig. 1 ~ 3, said copper soleplate 1 is fixedly connected on the back side of said packaging body 2; Both sides in said copper soleplate 1 bottom are respectively equipped with lateral process 11, and the lateral process 11 of corresponding said both sides, the side of said packaging body 2 is respectively equipped with side channel 1 and side channel 2 22.The height of lateral process 11 is approximately 1/5 of copper soleplate 1 whole height.

Distance between said side channel 1 and side channel 2 22 bottom lands is t, and the outward flange mutual spacing of said two lateral processes 11 is from being h, described t < h.That is to say that copper soleplate 1 must have the part that is in two side channels, can crimping live copper soleplate 1 to guarantee pressure column 3.As shown in Figure 6.

The width of said packaging body 2 is H, described h≤H.Economical with materials so on the one hand, on the other hand, copper soleplate 1 does not stretch out from the side, has certain safe effect.

The crown center position of said packaging body 2 is provided with inverted draw cut 23; Said inverted draw cut 23 forms an isosceles triangle with said side channel 1 and side channel 2 22, realizes the effect of 3 pressings.

The technique effect of the utility model: dispeled the operation of surface brush rubber behind the plastic packaging, saved artificial; Improve production efficiency, shortened the product process-cycle, practiced thrift 10 ~ 20% on the whole cost.
