Abstract
The utility model discloses a novel plastic envelope metal support, the plastic -packaged metal support comprises a material strip body, the material area body go up die -cut formations support center lamellar body and be in with the distribution the peripheral a plurality of bonding wire feet of support center lamellar body, the support center peripheral cover of lamellar body is equipped with the colloid, the bonding wire foot is the transversal arrangement card and locates in the colloid, the utility model has the advantages of novel in design, simple structure, efficient, with low costs, the mould is durable, and product quality is high, realizes that the solderless stitch exposes, improves material utilization rate, reduces the die cost and the production degree of difficulty.
Description
Technical field
The utility model relates to technical field of electronic products, particularly relates to a kind of Novel plastic-package metal support.
Background technology
The modern life all more and more be unable to do without electronic product, has a lot of electronic product all must use plastic packaging support, as the consumer electronics product such as mobile phone, TV; Large-scale indoor outer display screen, traffic lights; Automobile lamp and instrument and meter; Home lighting, commercial illumination, Landscape Lighting etc.
Existing plastic packaging support leaves gap when die-cut between pre-inserted support and bonding wire pin, adopt insert-molding when encapsulating in mould, during die laminating, plastic cement can flow out along cut gap strip material is thick, have to make boss on male die core inserts, avoid plastic cement to flow out.Boss together inserts in mother module core after inserting and closing between the pre-inserted support of metal support and bonding wire pin and forms a confined space, is plastic-packaged shape.As boss is oversize, metal support will be caused to be filed, form five metals burr, and easily and mother module core top touch and cause damage.As boss is undersized, will cause boss and have gap between pre-inserted support, bonding wire pin and mother module core, plastic packaging space is not airtight, and plastic material flows out, and forms plastic cement burr.
Blanking die is cold punching, is encapsulated as heat-seal in mould, and both are located by circular hole, circular hole itself has positioning error, moreover has and expand with heat and contract with cold, and causes and is difficult to overcome several difficult point: 1. require high as the hardware bracket precision of inserts, General Requirements progress +/-0.01, tolerance range 0.01; 2. the machining precision of inserts own is high, machining tolerance +/-0.005; 3. inserts inserts between the pre-inserted support of metal support and bonding wire pin, and need to wrap up handware very well, the fillet of processing is little, and difficulty of processing is high, more raises component costs; 4. male die core inserts inserts the boss height requirement +/-0.002 of five metals band; 5. seal for reducing costs in mould
Dress generally all adopt mould 256 cave i.e. 16 rows 16 to arrange, cumulative errors exist, high-precision process equipment is also difficult to meet the demands, must by hand one by one polishing cooperation, take time and effort; 6., by space constraint, male die core inserts size is less, the impact such as heat-shock, wearing and tearing, needs often to change.
Utility model content
The purpose of this utility model is to provide a kind of Novel plastic-package metal support for the deficiencies in the prior art, this plastic packaging metal support is novel in design, structure is simple, efficiency is high, cost is low, mould is durable, and product quality is high, realizes solderless stitch and exposes, improve stock utilization, lower die cost and production difficulty.
For achieving the above object, the utility model is achieved through the following technical solutions.
A kind of Novel plastic-package metal support, comprise material strip body, die-cut formation carriage center lamellar body and the multiple bonding wire pin being distributed in described carriage center lamellar body periphery on described material strip body, described carriage center lamellar body peripheral sleeve is provided with colloid, and described bonding wire pin is that lateral arrangement is arranged in described colloid.
Wherein, the step pitch of described carriage center lamellar body is 6.5mm.
Wherein, described bonding wire pin includes left bonding wire pin and backhand welding stitch, and the width of described left bonding wire pin is 0.9-1.1mm, and the width of described backhand welding stitch is 0.7-0.9mm.
Wherein, the thickness of described material strip body is 0.24-0.26mm.
The beneficial effects of the utility model are: a kind of Novel plastic-package metal support described in the utility model, comprise material strip body, die-cut formation carriage center lamellar body and the multiple bonding wire pin being distributed in described carriage center lamellar body periphery on described material strip body, described carriage center lamellar body peripheral sleeve is provided with colloid, described bonding wire pin is that lateral arrangement is arranged in described colloid, the utility model has modern design, structure is simple, efficiency is high, cost is low, mould is durable, product quality is high, realize solderless stitch to expose, improve stock utilization, lower the advantage of die cost and production difficulty.
Accompanying drawing explanation
Utilize accompanying drawing to be further detailed the utility model below, but the embodiment in accompanying drawing is not formed any restriction of the present utility model.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model carriage center lamellar body structural representation;
Fig. 3 is the structural representation at another visual angle of the utility model carriage center lamellar body.
Embodiment
Below in conjunction with concrete embodiment, the utility model is described.
As Figure 1-3, a kind of Novel plastic-package metal support, comprise material strip body 1, die-cut formation carriage center lamellar body 2 and the multiple bonding wire pin 3 being distributed in described carriage center lamellar body 2 periphery on described material strip body 1, described carriage center lamellar body 2 peripheral sleeve is provided with colloid 4, described bonding wire pin 3 is arranged in described colloid 4 in lateral arrangement, realizes solderless stitch and exposes, elegant in appearance.
Further, the step pitch L of described carriage center lamellar body 2 is 6.5mm, and traditional step pitch is 9mm, realizes carriage center lamellar body 2 and binds foot without the need to bending, thus reduce die cost and production difficulty, improve stock utilization.
Further, described bonding wire pin 3 includes left bonding wire pin 31 and backhand welding stitch 32, and the width D 1 of described left bonding wire pin 31 is 0.9-1.1mm, and the width D 2 of described backhand welding stitch 32 is 0.7-0.9mm, preferred 0.8mm.
Further, the thickness of described material strip body 1 is 0.24-0.26mm.
Need further explain, step pitch L of the present utility model has shortened, and the injection mould of same length can put into more carriage center lamellar body 2 product, thus improves mould efficiency.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
