Abstract
The utility model relates to a kind of copper alloy lead wire frame, comprises body, and one end of described body is provided with the termination for coated insulation material, and described termination is provided with through hole, and the both sides of described termination are respectively to upper turnover formation one Access Division.
Description
Technical field
The utility model relates to a kind of copper alloy lead wire 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.Existing a kind of copper alloy lead wire frame, its one end needs to be coated in other insulating material such as resin in follow-up making, but this lead frame due to size less, in order to easy to make, the termination of coated insulation material is only often that stamping-out has connecting hole, and does not do other process, and this just makes insulating material easily loosen, even get loose, cause contact instability to wait undesirable condition.
Utility model content
Therefore, for above-mentioned problem, the utility model proposes the copper alloy lead wire frame that a kind of structure is simple, covering property good, not easily get loose.
For achieving the above object, the utility model have employed following technical scheme: a kind of copper alloy lead wire frame, comprises body, and one end of described body is provided with the termination for coated insulation material, described termination is provided with through hole, and the both sides of described termination are respectively to upper turnover formation one Access Division.
Further, described termination is connected by a stage portion with body.
Further, described termination is electroplate with a nickel dam, nickel dam is electroplate with a layers of chrome.
Further, the below described termination being positioned at through hole is provided with a blocked hole, and the both sides of described blocked hole are respectively equipped with card adapter plate, and the bending direction of described card adapter plate is contrary with Access Division.
By adopting preceding solution, the beneficial effects of the utility model are: this copper alloy lead wire frame by arranging Access Division, thus makes termination have a good wedging position when coated insulation material, from but coated better effects if, more not easily loosen; Further, described termination is connected by a stage portion with body, and make termination opposing body have a sinking, make after coated insulation material, the surface of insulating material can be parallel with the surface of body; Further, because energising can be generated heat, it is softening that this just may make insulating material can generate heat under termination is energized for a long time, causes distortion, wait undesirable condition, and by electroless nickel layer and layers of chrome, the heating property of termination is reduced, thus protection insulating material; Further, by arranging blocked hole, and the card adapter plate on it can be setting up and down, thus coordinate with clamping insulating material with Access Division, thus make coated better effects if, more not easily loosens.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the end view of Fig. 1.
Embodiment
Now with embodiment, the utility model is further illustrated by reference to the accompanying drawings.
With reference to figure 1, Fig. 2, the present embodiment provides a kind of copper alloy lead wire frame, comprises body 1, and one end of described body 1 is provided with the termination 2 for coated insulation material, described termination 2 is provided with through hole 21, and the both sides of described termination 2 are respectively to upper turnover formation one Access Division 22.Described termination 2 is connected by a stage portion 23 with body 1.Described termination 2 is electroplate with a nickel dam, nickel dam is electroplate with a layers of chrome.The below described termination 2 being positioned at through hole 21 is provided with a blocked hole 24, and the both sides of described blocked hole 24 are respectively equipped with card adapter plate 25, and the bending direction of described card adapter plate 25 is contrary with Access Division 22.
This copper alloy lead wire frame by arranging Access Division, thus makes termination have a good wedging position when coated insulation material, from but coated better effects if, more not easily loosen; Further, described termination is connected by a stage portion with body, and make termination opposing body have a sinking, make after coated insulation material, the surface of insulating material can be parallel with the surface of body; Further, because energising can be generated heat, it is softening that this just may make insulating material can generate heat under termination is energized for a long time, causes distortion, wait undesirable condition, and by electroless nickel layer and layers of chrome, the heating property of termination is reduced, thus protection insulating material; Further, by arranging blocked hole, and the card adapter plate on it can be setting up and down, thus coordinate with clamping insulating material with Access Division, thus make coated better effects if, more not easily loosens.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; can make a variety of changes the utility model in the form and details, be protection range of the present utility model.
