Abstract
The utility model discloses a kind of lead frame for relatively high power electrical equipment, be made up of multiple lead frame unit, be interconnected by dowel between each lead frame unit, lead frame unit comprises fin and terminal pin, bend in fin and terminal pin junction, fin is provided with louvre and slide holder, described terminal pin is provided with reinforcement, this lead frame squeezes into reinforcement on terminal pin, change the shortcoming that original terminal pin is soft, strengthen frame structure hardness, can be widely used on the wiring board of relatively high power electrical equipment.
Description
Technical field
The utility model relates to a kind of lead frame.
Background technology
Lead frame is as the chip carrier of integrated circuit, it is a kind of electrical connection realizing chip internal circuits exit and outer lead by means of bonding material (spun gold, aluminium wire, copper wire), form the key structure part of electric loop, it serves the function served as bridge be connected with outer lead, all needing in the semiconductor integrated block of the overwhelming majority to use lead frame, is basic material important in electronics and information industry.
Utility model content
The technical problems to be solved in the utility model is to provide a kind of lead frame for relatively high power electrical equipment.
In order to solve the problems of the technologies described above, the utility model provides a kind of lead frame for relatively high power electrical equipment, be made up of multiple lead frame unit, be interconnected by dowel between each lead frame unit, it is characterized in that: described lead frame unit comprises fin and terminal pin, bend in fin and terminal pin junction, described fin is provided with louvre and slide holder, and described terminal pin is provided with reinforcement.
As further improvement of the utility model, the width of described lead frame unit is 11.405 ± 0.05mm.
As further improvement of the utility model, described louvre diameter is 3.85 ± 0.05mm.
As further improvement of the utility model, described fin thickness is 1.25 ± 0.02mm, and terminal pin thickness is 0.35 ± 0.02mm, and residing for fin and terminal pin, plane is at a distance of 2.6 ± 0.1mm.
Adopt said structure, its beneficial effect is: this lead frame squeezes into reinforcement on terminal pin, changes the shortcoming that original terminal pin is soft, strengthens frame structure hardness, can be widely used on the wiring board of relatively high power electrical equipment.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In figure: 1-lead frame unit, 2-fin, 3-terminal pin, 4-louvre, 5-slide holder, 6-reinforcement.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in more detail.
As shown in Fig. 1, a kind of lead frame for relatively high power electrical equipment, be made up of multiple lead frame unit 1, be interconnected by dowel between each lead frame unit 1, described lead frame unit 1 comprises fin 2 and terminal pin 3, bend in fin 2 and terminal pin 3 junction, described fin 2 is provided with louvre 4 and slide holder 5, described terminal pin 3 is provided with reinforcement 6, the width of described lead frame unit 1 is 11.405 ± 0.05mm, described louvre 4 diameter is 3.85 ± 0.05mm, described fin 2 thickness is 1.25 ± 0.02mm, terminal pin 3 thickness is 0.35 ± 0.02mm, residing for fin 2 and terminal pin 3, plane is at a distance of 2.6 ± 0.1mm.
This lead frame squeezes into reinforcement 6 on terminal pin 3, changes the shortcoming that original terminal pin 3 is soft, strengthens frame structure hardness, can be widely used on the wiring board of relatively high power electrical equipment.
Any employing and the similar lead frame designed by technical characteristic of the utility model will fall within protection range of the present utility model.
