Abstract
The utility model provides a signal transmission line comprising a plurality of circular metallic lines and insulating layers pasted on the surfaces of the circular metallic lines. The circular metallic lines are arranged at intervals in a row and in parallel and formed by left portions and right portions. The right portions are pasted on the insulating layers and are crushed to be in flat shapes while being pasted. The top surfaces of the free ends of the right portions are exposed in order to form terminal portions. The left portions are completely exposed in order to form soldering portions. Compared with a product in the prior art, the signal transmission line is different in that only one end of each circular copper line is crushed to form the terminal portions while the circular copper lines are pasted on the insulating layers. The signal transmission line has beneficial effects that the circular copper lines can be directly purchased and processing charge for crushing a whole copper line in an earlier stage is prevented such that cost is decreased; that the time of earlier-stage crushing processing is shortened, copper line delivery time is shortened, and time cost is reduced; and that production efficiency is improved.
Description
Technical field
The utility model relates to a kind of field of signal transmissions, relates in particular to a kind of signal transmssion line.
Background technology
FFC (Flexible Flat Cable) flexible flat winding displacement, is called for short winding displacement.FFC is widely used in connection use, LCDs, video camera, digital camera, phone, photocopier, wireless instruments instrument, audio-visual equipment and Aerospace Products etc. in computer, printer, scanner, automobile, medicine equipment, DVD, TV, MP3, MP4, CD-ROM, CD-ROM device, facsimile machine, 3C Product, the main function served as bridge that plays signal transmission, and can supporting corresponding connection.Frivolous, little, wear-resisting, the wet-heat resisting of taking up room, resistance to complications, warping strength etc., stable and reliable for performance, can carry out on demand EMI control, characteristic impedance control.
Existing FFC line is made up of flat copper wire and the insulating barrier that fits in flat copper wire upper and lower surface, and this structure has following shortcoming:
1, Costco Wholesale is high: heart yearn is flat copper wire, its by circular copper wire early stage carry out whole piece flatten process, materials processing cost is higher;
2, time cost is high: the operation that flatten copper cash many early stages together, such as: supplier need to flatten processing to the circular copper wire of independent procurement or production and process, and repeatedly, the friendship phase is long for process.
Summary of the invention
The purpose of this utility model is to provide a kind of signal transmssion line, overcomes the defect that processing charges is high, time cost is high because of early stage, whole piece heart yearn flattening processing being caused in prior art, enhances productivity, and reduces production costs and processing cost.
The purpose of this utility model is achieved through the following technical solutions.
A kind of signal transmssion line, comprising: complex root circular metal line and the insulating barrier that fits in described circular metal line surface;
Described circular metal line is row's parallel interval to be arranged, and is made up of left part and right part; Described right part and insulating barrier laminating, in laminating, right part is pressed into flat, and the free-ended upper surface of this right part is exposed to outer to be formed as portion of terminal; Described left part is exposed to outer to be formed as weld part completely.
Wherein, described circular metal line is circular copper wire.
Wherein, the length of the right part of described circular metal line is greater than the length of left part.
Wherein, described insulating barrier comprises insulating barrier and lower insulating barrier, and described upper insulating barrier fits in the right part upper surface of all circular metal lines, lower insulating barrier and fit in the right part lower surface of all circular metal lines.
Wherein, also comprise a stiffening plate, this stiffening plate fits in the outer surface of lower insulating barrier, is positioned at the correspondence position of described portion of terminal.
Wherein, described upper insulating barrier, lower insulating barrier and stiffening plate are PET material.
Wherein, described portion of terminal and the first electric connector are pegged graft, and form and electrically conduct with this first electric connector.
Wherein, described weld part and the second electric connector welding, form and electrically conduct with this second electric connector.
Compared with prior art, difference is only one end of circular copper wire to be flattened and formed portion of terminal in circular copper wire laminating insulating barrier the utility model, and beneficial effect is:
1, Costco Wholesale is low: directly buy circular copper wire, save supplier's processing charges.
2, time cost is low: reduced the time of flattening processing early stage, reduced the time that copper cash is processed outside factory, shortened the copper cash delivery time.
3, production efficiency is high: comprehensive above-mentioned 2 points, and in factory, laminating adds the flattening of circular copper wire in man-hour one end, can play saving cost, reduces the copper cash process-cycle, thus the effect of enhancing productivity.
Brief description of the drawings
Fig. 1 is the explosive view of signal transmssion line in the utility model embodiment;
Fig. 2 is the overall structure figure of signal transmssion line in the utility model embodiment.
Embodiment
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, the utility model is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the utility model, and be not used in restriction the utility model.
Shown in Fig. 1 and Fig. 2, in the present embodiment, signal transmssion line comprises: upper insulating barrier 1, circular copper wire 2, lower insulating barrier 3, stiffening plate 4.
Upper insulating barrier 1 and lower insulating barrier 3, adopt PET material, plays insulating protection effect, fits in respectively the upper and lower surface of complex root circular copper wire 2.
Circular copper wire 2 includes complex root and is parallel interval to be arranged, and as heart yearn, plays conducting effect.Circular copper wire 2 comprises the left part 21 and the right part 22 that are one, left part 21 is exposed to outer using as weld part completely, the upper and lower surface of right part 22 is fitted with upper insulating barrier 1 and lower insulating barrier 3 respectively, with insulating barrier laminating in right part 22 be pressed into flat completely, and the free-ended upper surface of right part 22 is exposed to outer using as portion of terminal.Portion of terminal is in order to peg graft with the connector mating, and weld part is in order to weld mutually with the connector mating, due to the easy space distance control of flat wire, the convenient winding displacement of making, so the length of reserved right part 22 and the length of left part 21 will be grown.
Stiffening plate 4, fits in respectively the outer surface of lower insulating barrier 3, corresponding to the position of portion of terminal, plays and strengthens the intensity of portion of terminal and the effect of thickness, and FFC terminal thickness and connector grafting thickness are matched, and facilitates grafting.
