The novel SAS connecting line with good bendability is beneficial to processing, facilitates wiring, and saves processing cost and material cost. In addition, each SAS wire assembly can be used individually.

Description

A kind of Novel SAS connecting line

Technical field

The utility model belongs to the holding wire technical field, relates to signal connecting line, specifically a kind of Novel SAS connecting line.

Background technology

The SAS interface specification is the new interfaces that parallel scsi interface is developed afterwards.The design of this interface is for the usefulness of improving storage system, availability and extendibility, has good using value and prospect.The SAS connecting line is generally formed by data wire and power wire combination, and wherein data wire is generally being fixedly installed.Conventional SAS (Serial Attached SCSI, serial SCSI) connecting wire structure has three kinds at present:

1. adopt the multicore insulated wire as inner core, and adopt the PVC material as outer quilt, utilize simultaneously the mode of extrusion to complete the making of SAS connecting line.This type of connecting line is due to employing extrusion mode, so the line body thickness is large, and the integrated connection line volume is large, not flexible and assembling.See Fig. 1.

2. adopt independent list that SAS and electric wire are made up, but outer electric wire is very in disorder without fixing, and adds and man-hour easily occurs the PIN bit-errors.See Fig. 2.

3. directly fixing to electric wire with up and down hot melt composite layer, although this mode volume is little than the first production method, crooked and assembling also has reinforcement, but because the higher up and down hot melt composite layer that easily occurs after long-term use of the temperature of cabinet scatters, the signal transmission performance meeting complete failure in case scatter, this kind later stage failure risk is very large.See Fig. 3.

Summary of the invention

The purpose of this utility model is to provide a kind of good bandability, is beneficial to processing, facilitates distribution, and saves the Novel SAS connecting line of processing cost and material cost, to overcome deficiency of the prior art.

For realizing above-mentioned utility model purpose, the utility model has adopted following technical scheme:

A kind of Novel SAS connecting line comprises at least two data splitting lines, and described data splitting line comprises a pair of holding wire that is arranged side by side, and described holding wire is made of conductive core and external insulation layer; It is characterized in that, described data splitting line also comprises the pair of lamina coating layer, and described double-coated layer wraps other part in described data splitting line; Described double layer material comprises internal layer screen and outer fixed bed, and described data splitting line is arranged in same plane side by side, and a continuous heatmeltable material layer is coated and fixed described data splitting line together.

SAS connecting line described in the utility model, first separately employing namely have shielding action and have again a pair of holding wire and other part that the double-coated material of fixation wraps for the signal transmission and form the data splitting line.Then each data splitting line is coated and fixed by hot-melting material together.Adopt this scheme namely can reach the connecting line volume little, flexible texts because holding wire to independent coating, can prevent the breakage of appearance hot melt composite layer, causes the serious problems such as signal line transmitting effect inefficacy again.

In technique scheme, described data splitting line can be one or more.According to actual needs, be generally four, six, nine or 12.

As improvement, described data splitting line also comprises ground wire, and described ground wire and data wire are fixing side by side.In described data splitting line, preferably include two ground wires, the holding wire that is placed in is to both sides.

SAS connecting line described in the utility model can also comprise power line as required, and as current delivery, its quantity can be one or more as required, in actual making, is generally two or four.

As improvement, in order further to improve the stability of connecting line, prevent that power line from producing electromagnetic interference to data wire, can also be outside described power line wrapped one deck aluminium foil etc. have the material of signal shielding function as screen.This screen can be wrapped separately for every power line, also several power lines can be done as a whole unification wrapped.

In such scheme, the material of described hot-melting material layer is preferably hot melt aluminium foil or heat is melted PET, and the material of described screen is preferably aluminium foil.

Compared with prior art, the utility model also has following beneficial effect:

1) intermediate module is independent SAS connecting line, and every a pair of independent use mutually guaranteed anti-EMI performance, and can have been guaranteed effectively that properties meets the SAS standard-required;

2) can increase as required electric wire in intermediate module and use as Current Control, need not to increase in addition power line, reduce waste of material;

3) the outer hot melt composite material that adopts is fitted, easily peeling, and the manufacturing process cost is saved in easily processing, and, because the hot melt thickness of composite material is thin, can make the structure miniaturization more of operative installations, lighter, more pliable and tougher, cabling is more convenient.

Embodiment

With reference to Fig. 4, in this example, SAS connecting line described in the utility model comprises: continuously every four data splitting lines 1 and four power lines 2 of arranging, described four power lines are arranged side by side in the centre side by side, described four data splitting lines four power line left and right sides that are placed in twos.Described data splitting line comprises two signal line, two ground wires, the wrapped aluminum foil material in outside as screen, and outermost layer melts composite material with heat and is coated and fixed.Described data splitting line and power line general up and down hot melt composite layer 3 be adhesively fixeds, the edge directly is adhesively fixed for up and down hot melt composite layer.

With reference to Fig. 5,6, SAS connecting line shown in this two figure is substantially identical with connecting wire structure shown in Figure 4, and difference is, SAS connecting line shown in Figure 5 comprises two data splitting lines and two power lines, wherein two power lines are done as a wholely, and the wrapped one deck aluminum foil material in outside is as screen.SAS connecting line shown in Figure 6 and product difference shown in Figure 5 only are power line lapped shielding layer not outward.

Be only below concrete exemplary applications of the present utility model, protection range of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
