Abstract
The utility model relates to a kind of symmetrical expression TO-220 type frame structure, and comprise top strength and separate unit, separate unit symmetry is positioned at strength both sides, described top, separate unit also has top connect muscle, and top strength connects muscle with top and is directly connected.Separate unit also has chip installation area, and chip installation area also has radiating part, and pin is positioned at bottom, chip installation area.Connect muscle, middle muscle and end muscle by top strength, top multiple separate unit coupled together and forms packaging frame.This programme makes the frame number of entering in production process be former twice, effectively raises production efficiency.
Description
Technical field
The utility model relates to IC manufacturing field, particularly a kind of integrated circuit frame structure, is specifically related to a kind of TO-220 type frame structure.
Background technology
In electronic circuitry design, the rectifying device of TO-220 packing forms is used widely.Traditional TO-220 packaging frame is combined by frame and encapsulation unit, and encapsulation unit is connected in series.Framework injection once can only fill 20 products in process of production, uses conventional package framework production efficiency low.
Because above-mentioned defect, the design people, actively in addition research and innovation, to founding a kind of novel TO-220 frame structure, make it have more value in industry.
Utility model content
For solving the problems of the technologies described above, the object of this invention is to provide a kind of symmetrical expression TO-220 type frame structure.Frame structure is originally connected by top strength, forms symmetrical structure, add the size of framework one times, improve production efficiency.
For realizing above order ground, the technical solution of the utility model is as follows:
A kind of symmetrical expression TO-220 type frame structure, comprise top and connect muscle and separate unit is formed, separate unit symmetry is positioned at Lian Jin both sides, top, separate unit has top muscle, and top connects muscle and is directly connected with described top muscle.Connect muscle by top, top muscle, middle muscle and end muscle couple together multiple separate unit and form packaging frame.
Further, the connected mode that the top that top connects muscle and both sides connects muscle is formed in one.
Further, separate unit also has chip installation area.
Further, separate unit also has radiating part, adjacent two radiating parts connect muscle by top and connect.
Further, middle muscle connects the pin on each yuan of separate single, and wherein, pin is positioned at below chip installation area, and both sides pin is arranged in pin both sides.Both sides pin also has pin pressure welding area, and pin is positioned at the below of both sides pin.
By such scheme, the beneficial effects of the utility model are:
By this programme, make the frame number of entering in production process be before twice, effectively raise production efficiency.
Above-mentioned explanation is only the general introduction of technical solutions of the utility model, in order to better understand technological means of the present utility model, and can be implemented according to the content of specification, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
Accompanying drawing explanation
Fig. 1 vertical view of the present utility model
Embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the utility model, but are not used for limiting scope of the present utility model.
As shown in Figure 1, symmetrical expression TO-220 type frame structure, comprise top and connect muscle 1, be symmetrically distributed in the separate unit 200 that top connects muscle 1 both sides, each separate unit 200 comprises top muscle 2, radiating part 3, chip installation area 4, middle muscle 5, middle limb 6, both sides pin 7, end muscle 8 form.
Top connects muscle 1 and is formed in one with the top muscle 2 of both sides, and separate unit 200 symmetrical expression is positioned at top and connects muscle 1 both sides.
Separate unit 200 is provided with chip installation area 4, for the installation of subsequent handling chip.Chip installation area 4 has radiating part 3, adjacent two radiating parts 3 are wanted to connect by top muscle 2.Radiating part 3 installs fin for subsequent handling, plays to mounted chip cooling effect.
Middle muscle 5 is for connecting each pin on separate unit 200, and wherein, pin 6 is positioned at below middle part, chip installation area 4, and both sides pin 7 is arranged in pin 6 both sides.Both sides pin 7 also has pin pressure welding area 71, and connect chip by aluminium wire, pin 72 is positioned at the below of both sides pin 7.End muscle 8 is for the bottom of each pin of connection encapsulation framework.Connect muscle 1 by top, top muscle 2, middle muscle 5 and end muscle 8 couple together multiple separate unit 200 form packaging frame.
The above is only preferred implementation of the present utility model; be not limited to the utility model; should be understood that; for those skilled in the art; under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and modification, these improve and modification also should be considered as protection range of the present utility model.
