Abstract
The invention belongs to the technical filed of an appliance in the technical field of electronic information, especially relates to a cable tetra-head vertical wrapping mold, and discloses a cable tetra-head vertical wrapping mold. The cable tetra-head vertical wrapping mold comprises a bearer. Four circular trough holes are uniformly distributed on the bearer by taking the central point of the bearer as a center, the two ends of an aluminum foil fixing device are fixed on the outer sidewall of an aluminum foil gradual change groove, the middle of the aluminum foil fixing device is provided with an arc member, the arc member is arranged in the aluminum foil gradual change groove, and an aluminum foil guiding seam is reserved between the arc member and the aluminum foil gradual change groove. According to the invention, the aluminum foil wrapping stability is improved, and through the combination of the aluminum foil gradual change groove, the aluminum foil fixing device and an aluminum foil closing end, aluminum foil wraps a cable in a gradual changing mode.
Description
Technical field
The invention belongs to electronic information technical field apparatus technical field, relate in particular to a kind of cable four-head longitudinal covering model.
Background technology
Line adopts to shield technology bag and the two kinds of modes of vertical bag of dragging, and multi-thread to symmetrical cable in, it is main dragging packet mode to be generally used for total shielding, vertical packet mode is main for line to shielding.Longitudinal covering model tool originally, just adopts common porcelain eye or the mould of cylindrical bore, and line to passing moulding from the hole of mould with aluminium foil.Although this way makes aluminium foil can envelope line pair, but there are several defects: 1, can not guarantee that healing up of aluminium foil is in outward direction, when cable transmission frequency is very high be, the wavelength of signal formation is just very short, the slot leakage of easily healing up by aluminium foil is gone out, when two aluminium foils heal up while relatively approaching, will cause the defective or undesirable of cross-talk performance; 2, may there is the phenomenons such as upset fold in aluminium foil, when the coated direction of aluminium foil and stranding direction of lay are when inconsistent, cause that aluminium foil is coated to fluff, form four lines the coated degree of tightness of aluminium foil is differed, cause the electric capacity of shielded pair inhomogeneous, have a strong impact on electric property and the outward appearance of cable.
Summary of the invention
The object of the invention is to solve above-described technical problem, a kind of cable four-head longitudinal covering model is provided, its technical scheme is as follows:
A kind of cable four-head longitudinal covering model, it is characterized in that, described cable four-head longitudinal covering model comprises bearing, on described bearing, centered by the central point of bearing, uniform parts has four manholes, described bearing is provided with and four manholes coated mould of aluminium foil one to one, and the coated mould of four described aluminium foils is drawn close to the central axis of bearing gradually; The coated mould of described aluminium foil comprises aluminium foil gradual change groove, the front of aluminium foil gradual change groove is the arcwall face drawing in gradually, aluminium foil gradual change groove forms the aluminium foil end that heals up by shrinking gradually to the one end away from bearing near one end of bearing to close up, aluminium foil gradual change groove and aluminium foil heal up and are provided with aluminium foil fixture between end, the two ends of aluminium foil fixture are fixed on the lateral wall of aluminium foil gradual change groove, the centre of aluminium foil fixture is an arcuate member, in arcuate member setting and aluminium foil gradual change groove, between arcuate member and aluminium foil gradual change groove, leave aluminium foil guide slit.
Cable four-head longitudinal covering model provided by the invention, aluminium foil is through manhole when in use, pass through the aluminium foil guide slit of aluminium foil fixture along aluminium foil gradual change groove, again through the aluminium foil end that heals up, enter foil moulding mould, form four pairs of lines pair that aluminium foil is coated, then fix through cable core shaper through stranded, form qualified cable core.
The present invention passes a whole set of mould aluminium foil according to the track of Design of Dies, and then line, to the aperture forming along aluminium foil through mould, is connected to take-up reel.Open after stranding, aluminium foil and line are to the formation along with pitch, form stable cable core, fixing due to the coated direction of aluminium foil of longitudinal covering model tool and the direction of healing up simultaneously, in the cable core forming, the position of aluminium foil remains unchanged always, forms four lines aluminium foil is healed up to position consistency towards cable core outside, has avoided crosstalking of signal.
The invention has the beneficial effects as follows: one: solve cross-talk performance unfavorable condition, reach this effect by the fixing aluminium foil position that heals up; Two: improve aluminium foil coated stability, by the heal up combination of end of aluminium foil gradual change groove, aluminium foil fixture and aluminium foil, make being coated on cable of aluminium foil gradual change.
Brief description of the drawings
Fig. 1 is schematic diagram of the present invention.
Embodiment
Illustrate embodiment below in conjunction with Fig. 1:
A kind of cable four-head longitudinal covering model, it is characterized in that, described cable four-head longitudinal covering model comprises bearing 1, on described bearing 1, centered by the central point of bearing 1, uniform parts has four manholes 2, described bearing 1 is provided with and four manholes 2 coated mould 3 of aluminium foil one to one, and the coated mould 3 of four described aluminium foils is drawn close to the central axis of bearing gradually; The coated mould 3 of described aluminium foil comprises aluminium foil gradual change groove 4, the front of aluminium foil gradual change groove 4 is the arcwall face drawing in gradually, aluminium foil gradual change groove 4 forms aluminium foil and heals up and hold 5 by shrinking gradually to the one end away from bearing 1 near one end of bearing 1 to close up, aluminium foil gradual change groove 4 and aluminium foil heal up and are provided with aluminium foil fixture 6 between end 5, the two ends of aluminium foil fixture 6 are fixed on the lateral wall of aluminium foil gradual change groove 4, the centre of aluminium foil fixture 6 is an arcuate member 7, in arcuate member 7 settings and aluminium foil gradual change groove 4, between arcuate member 7 and aluminium foil gradual change groove 4, leave aluminium foil guide slit 8.
Cable four-head longitudinal covering model provided by the invention, aluminium foil is through manhole when in use, pass through the aluminium foil guide slit of aluminium foil fixture along aluminium foil gradual change groove, again through the aluminium foil end that heals up, enter foil moulding mould, form four pairs of lines pair that aluminium foil is coated, then fix through cable core shaper through stranded, form qualified cable core.
The present invention passes a whole set of mould aluminium foil according to the track of Design of Dies, and then line, to the aperture forming along aluminium foil through mould, is connected to take-up reel.Open after stranding, aluminium foil and line are to the formation along with pitch, form stable cable core, fixing due to the coated direction of aluminium foil of longitudinal covering model tool and the direction of healing up simultaneously, in the cable core forming, the position of aluminium foil remains unchanged always, forms four lines aluminium foil is healed up to position consistency towards cable core outside, has avoided crosstalking of signal.
Product involved in the present invention belongs to electronic information technical field, and product is that line is to shielding symmetrical cable, such as CAT6A, CAT7, CAT7A and other need the cable of line to shielding.Its transmission frequency generally, more than 500MHz, is applicable to the environment such as signal disturbs by force, high pressure, highfield.
Product is mainly used in wiring system and machine room between building, and what meet the data-signals such as high-quality audio frequency, video, image carries out high-speed transfer and exchange under high-intensity electromagnetic interference.
