Abstract
The utility model discloses a lead frame package reel, comprising two disks (1) and a disk core (2); the outer end surface of each disk (1) is provided with a strengthening rib, the disk (1) is a plastic disk and the disk core (2) is a plastic disk core. The lead frame package reel comprises two disks (1) and one disk core (2), the outer end surface of each disk (1) is provided with a strengthening rib, the disk (1) is a plastic disk and the disk core (2) is a plastic disk core. By adopting the structure, as the outer end surface of each disk is provided with the strengthening rib, the structure is very firm and the bearing capacity is strong (more lead frame package reels can be wound). Meanwhile, the disk and the disk core are plastic bodies which not only have intensity but also have toughness, and the lead frame package reel is not easy to deform and can be used repeatedly, and the service life is long.
Description
Technical field
The utility model relates to a kind of packing technique field of electronic component, specifically is a kind of lead frame packing reel.
Background technology
Lead frame is the semiconductor encapsulated element that a kind of metal is made, generally in the form of sheets or be the winding shape.The packing of lead frame finished product is divided into two kinds of boxlike and disk types, wherein box-packagedly is used to pack the sheet lead frame, and the disk type packing is used to pack winding shape lead frame.At present, existing lead frame disk type packing is made up of two disk limits and a solid dish core, and two disks and a dish core all are to make with paper material (as fluting board), and are with glue they to be bonded together, thereby form a reel.But there is following shortcoming in this lead frame packing reel:
1. because its disk is a light face, so insufficient strength, all carryings in light weight promptly can only be around the lead frame of minority.
2. because two disks coil core and bond together with glue with one, so structure is firm inadequately, service life is very short; Simultaneously disk can not split with the dish core, and it is bigger therefore to deposit shared space.
3. because two disks are with a dish core is that paper material (as fluting board) is made, this lead frame packing reel repeated use several times after, be easy to be out of shape, thereby lose protective effect lead frame.
The utility model content
Technical problem to be solved in the utility model is, provide a kind of sound construction, load-carrying capacity by force, not yielding, can repeated usage, long service life and can disassembled and assembled freely, deposit the lead frame packing reel that takes up room little.
For solving the problems of the technologies described above, a kind of lead frame packing reel that the utility model provides comprises two disks and a dish core, is equipped with reinforced rib on the outer face of described each disk, and described disk is a plastic disc, and described dish core is the vinyl disc core.
After adopting above structure, the utility model compared with prior art has the following advantages: owing on the outer face of each disk, be equipped with reinforced rib, so structure is very firm, load-carrying capacity strong (can twine more lead frame).Disk and dish core are plastic body simultaneously, and existing intensity is flexible again, and not yielding, energy repeated usage, longer service life.
As improvement, described reinforced rib comprises a plurality of circumferential reinforced ribs and a plurality of radial reinforced rib, and the center of circle of described a plurality of circumferential reinforced ribs is identical, and described radial reinforced rib is along the periphery rectangular distribution of disk.Adopt circumferential reinforced rib and radial reinforced rib, make the structure of disk more firm, load-carrying capacity is stronger, and is more not yielding.
As further improvement, core is removable is connected with dish respectively for described two disks.Adopt this removable connection, disk and dish core can be made up by disassembled and assembled freely, occupation space is also little when therefore depositing.
As further improving, described removable connection is meant that described dish core is two semicircle fillets, and two sides of each fillet are equipped with several side buttons, described disk is provided with several and buckles the square hole that matches with side, and described square hole is along the circumferencial direction rectangular distribution of disk.Adopt the removable connection of button, make dismounting more convenient.

The utility model: 1, disk; 2, dish core; 3, circumferential reinforced rib; 4, radial reinforced rib; 5, square hole; 6, side button.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is done explanation in further detail.
By the structural representation of Fig. 1, prior art lead frame shown in Figure 2 packing reel as can be known, it is made up of two disks 1 ' and a solid dish core 2 ', the end face of each disk 1 ' is the light face, two disks 1 ' and a dish core 2 ' all are to make with paper material (as fluting board), and be they to be bonded together, thereby form a reel with glue.
By the structural representation of the utility model lead frame packing reel of Fig. 3～shown in Figure 7 as can be known, it comprises two disks 1 and a dish core 2, be equipped with reinforced rib on the outer face of described each disk 1, described disk 1 is a plastic disc, and described dish core 2 is the vinyl disc core.Described reinforced rib comprises a plurality of circumferential reinforced ribs 3 and a plurality of radial reinforced rib 4, and the center of circle of described a plurality of circumferential reinforced ribs 3 is identical, and described radial reinforced rib 4 is along the periphery rectangular distribution of disk 1.Described two disks 1 respectively with the dish 2 removable connections of core.Described removable connection, be meant that described dish core 2 is two semicircle plastics fillets, two sides of each fillet are equipped with several side buttons 6, and described disk 1 is provided with several and buckles 6 square holes that match 5 with side, and described square hole 5 is along the circumferencial direction rectangular distribution of disk 1.Described side button 6 is barb-shaped.
When using this lead frame packing reel, the barb-shaped side of dish core 2 sides of two semicircle narrow strip is buckled in 6 square holes 5 that are anchored on the disk 1, utilize barb that side button 6 is stuck in the square hole 5, the side that to coil core 2 another sides is again buckled 6 and is buckled in the square hole 5 of another disk 1, has so just formed the packing reel of a lead frame.
When this lead frame packing reel time spent not, can take out the square hole 5 of side button 6 from disk 1, disk 1 and dish core 2 are just broken away from fully come, just can save very big space when depositing.
It is fixed that the weight that the circumference reinforced rib 3 in the utility model on disk 1 outer face and the quantity of radiation reinforced rib 4 can be carried lead frame is according to actual needs come, and weight is heavy more, and quantity is many more; Weight is light more, otherwise then.
