Abstract

A thin type short pitch LED lead wire frame, comprising a technical edge. Technical holes are arranged on the technical edge, a plurality of LED lead wires of two pins are vertically connected with the technical edge, an upper reinforcing connection line is used for connections among the LED lead wires of two pins, the distance between the center lines of two adjacent LED lead wires of two pins, i.e. the pitch is less than 7.62 mm, and the thickness of a steel strip used for manufacturing the lead wire frame is less than 0.5 mm. In the utility model, the distance between the center lines of two adjacent LED lead wires of two pins is reduced and the thickness of the used steel strip is decreased, and thereby more LED lead wires of two pins can be arranged on each lead wire frame, the usage amount of the steel strip is reduced, and the cost is lowered.

Description

Short-pitch thin LED lead frame

Technical field

The utility model relates to the lead frame that a kind of LED of production is a Light-Emitting Diode, particularly a kind of short-pitch thin LED lead frame.

Background technology

LED is that light emitting diode belongs to the environmental protection light source, find broad application at indicator lamp, ornament lamp, Landscape Lamp, torch with light fixtures such as lamp, traffic lights, auto lamp, road lighting lamps, progressively will replace the traditional lighting lamp, LED with peculiar cold light source, energy consumption is low, efficient is high, the life-span is long etc., and performance makes its purposes more and more wider, but because encapsulation cost of manufacture height, cause the LED cost higher, influenced and hindered utilization and the development of LED.The general lead frame technology edge lengths of present direct insertion LED encapsulation is 152.4 millimeters, and pitch is 7.62 millimeters, and thickness of strips is 0.5 millimeter, and pitch is bigger, makes steel band thicker, has increased the consumption of steel band.

Summary of the invention

The purpose of this utility model is to provide a kind of on the basis that ensures the LED quality, reduces the steel using amount of LED lead frame, the short-pitch thin LED lead frame that reduces production costs.

The purpose of this utility model is achieved in that a kind of short-pitch thin LED lead frame, comprise the technology limit, evenly have fabrication hole on the technology limit, vertical many LED two pin leads that are connected with the technology limit, connect by the last muscle that connects between LED two pin leads, the distance between adjacent two LED, the two pin leads center lines is that pitch a is less than 7.62 millimeters.Be used to make the thickness of strips of lead frame less than 0.5 millimeter.Distance between adjacent two LED, the two pin leads center lines is that pitch a is 5.08 millimeters.The thickness of strips that is used to make lead frame is 0.4 millimeter.

The short-pitch thin LED lead frame that the utility model provides, the distance that has shortened between two LED, the two pin leads center lines adjacent on the single LED lead frame is a pitch, can arrange more LED two pin leads on former 20 every the lead frame.LED lead frame pitch is 5.08 millimeters, thickness of strips 0.4 for the LED lead frame of millimeter just is 7.62 millimeters than traditional pitch, and thickness of strips is 0.5 millimeter LED lead frame steel band consumption saving 46.66%, has reduced production cost.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is a structural representation of the present utility model.

The specific embodiment

As shown in Figure 1, the utility model comprises technology limit 1, evenly has fabrication hole 2 on the technology limit 1, with technology limit 1 vertical many LED two pin leads 3 that are connected with, connects by the last muscle 4 that connects between LED two pin leads 3.

In the utility model, lead frame technology edge lengths b is 152.4 millimeters, and is identical with the length of common lead frame.Distance between adjacent two LED, two pin leads, 3 center lines is that pitch a is less than 7.62 millimeters, it is 7.5 millimeters, 7.1 millimeters, 6.8 millimeters, 6 millimeters, 5.8 millimeters, 5.1 millimeters, 5.08 millimeters, 5.01 millimeters, 4.98 millimeters etc., satisfying the shortening of pitch a that tries one's best under the prerequisite of technological requirement, to save the steel band consumption.

The thickness of strips that is used to make lead frame is less than 0.5 millimeter, and commonly used is 0.4 millimeter.
