Abstract

The utility model discloses a connector wire rod, which comprises two signal-pairs, a plurality of ground wires and a tegument, wherein each signal-pair comprises two signal wires, each of which comprises a conductor and an insulation layer which is wrapped on the conductor; the insulation layer is a foamed polyethylene layer, and the signal-pair is also wrapped with a insulation layer which is a conductive polyethylene layer; and, the signal wire is positioned next to the ground wire, so as to avoid the interference; besides, the signal-pair and the ground wire can be wrapped by the tegument which is used as a protection layer. The utility model, while being in the process of barking, the conductive polyethylene layer and the foamed polyethylene layer and the tegument can be barked at one time; then the later process can be done directly, the processing operation is simple and the bad hidden danger of high voltage and short circuit is avoided.

Description

A kind of connector wire rod

Technical field

The utility model relates to a kind of electric power connector wire rod, relates in particular to a kind of SATA wire rod.

Background technology

Conventional at present SATA wire rod, as shown in Figure 1, this SATA line 10 mainly comprises the serving 103 of four holding wires, four ground wires 102 and an above-mentioned holding wire of parcel and ground wire 102, wherein, this holding wire is made up of the insulating barrier 1012 of a conductor 1011 and this conductor 1011 of parcel, and the binary signal line is formed a signal to 101, and a screen 1013 is coated on above-mentioned signal to 101 insulating barrier 1012 outsides, and this SATA line 10 is to draw as its screen 1013 with hot melt aluminium foil wheat.

Technique scheme is in wire rod processing peeling, and hot melt aluminium foil wheat draws stripping unclean, needs one special jewelling paper tinsel operation that aluminium foil is pressed in the polyvinyl chloride serving 103, if aluminium foil does not press, then can cause the situation of high pressure and poor short circuit.

Summary of the invention

In view of the above problems, the purpose of this utility model is to provide a kind of novel electronic connector wire rod, has saved the operation of jewelling paper tinsel, and has reduced the situation of high pressure and poor short circuit.

In order to achieve the above object, the utility model adopts following technical scheme: a kind of connector wire rod, it comprises that mainly binary signal is to, some ground wires and an outer quilt, wherein, each signal is to comprising the binary signal line, and each holding wire comprises that a conductor and is coated on the insulating barrier of this conductor outside, and this insulating barrier is a polyethylene foamed layer, and each signal also is enclosed with a screen to the outside, and this screen is a conductive polyvinyl chloride layer; Again, the adjacent setting of holding wire and ground wire is to avoid interference; In addition, this outer quilt can be wrapped up above-mentioned binary signal simultaneously to reaching ground wire, plays protective layer.

Preferable, the utility model provides a kind of connector wire rod, and wherein, described ground wire can be four, the corresponding ground wire of each holding wire.

Preferable, the utility model provides a kind of connector wire rod, and wherein, described ground wire can be three, and middle two holding wires are shared a ground wire.

Compared to prior art, the connector wire rod that the utility model disclosed, this connector wire rod not only meets the high-frequency parameter test request of SATA association, and utilize conductive polyvinyl chloride to replace conventional hot melt aluminium foil wheat to draw as screen, processing during peeling can with outside peeled off in the lump by, screen and insulating barrier, save the operation of jewelling paper tinsel, and reduced the situation of high pressure and short circuit.

Embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Please refer to shown in Figure 2ly, be cross-sectional view of the present utility model.In present embodiment, described connector wire rod 20 mainly comprise binary signal to 201, four ground wires 202 and a parcel signal to 201 and ground wire 202 outer by 203.

Wherein, each signal comprises the binary signal line to 201, this equisignal line is respectively one and is just reaching a negative signal line, and each holding wire is corresponding with a ground wire 202, disturb to get rid of, and each holding wire comprises that a conductor 2011 and is wrapped in the insulating barrier 2012 of these conductor 2011 outsides, this insulating barrier 2012 is a polyethylene foamed layer, dielectric as conductor, and in order to the situation of avoiding being short-circuited between conductor 2011 and the ground wire 202, again, each signal is wrapped with a screen 2013 to 201 external packets, this screen 2013 is a conductive polyvinyl chloride layer, in order to avoid the interference of outer bound pair holding wire, played the good signal shielding action, and it utilizes the conductive polyvinyl chloride properties of materials, by the high temperature (being generally 106 ℃～180 ℃) of extrusion, with these conductive polyvinyl chloride plastics, outside reaching, this polyethylene foamed insulating barrier 2012 is bonded together by 203.

In addition, this is outer to be coated on this binary signal to 201 and these ground wire 202 outsides by 203, plays the effect of guard signal line and ground wire 202.

Moreover, as shown in Figure 3, be another execution mode of the present utility model.Wherein, this wire rod 30 also can be set to only have the SATA wire rod of three ground wires 302, two holding wires are shared a ground wire 302 in the middle of promptly being, all the other two holding wires are a corresponding ground wire 304,305 respectively, so, not only saved a ground wire, and easy to process during than four ground wires, do not needed the two ground wires arrangements in centre and be riveted together.

The utility model is when the processing peeling, the screen 2013 of this conductive polyvinyl chloride, the insulating barrier 2012 of this polyethylene foamed and polyvinyl chloride are outer can disposablely be peeled off by 203, and peeling is very clean, noresidue rubber, can directly do back segment processing (as welding, riveted joint etc.), manufacturing procedure is simple, the hidden danger of no high pressure and poor short circuit.
