Abstract

The invention discloses a utility model of a cable. The cable consists of a wire material (10) in the middle of the cable for transmitting signals, a protecting layer (12) coated on the wire material, and an outer coating layer (13) formed on the protecting layer. The wire material includes multiple combined wires (11). The two ends of the wire material have twisted pair structure. The middle part of the wire material has parallel wire structure.

Description

Cable

[technical field]

The utility model relates to a kind of cable, refers to a kind of cable that is connected to electric connector and is used for transmission signals especially.

[background technology]

The parallel line structure is present industry two kinds of wire rod structures commonly used with strand to line structure; Both comparatively speaking; Parallel line wire rod high frequency performance is (like delay of signals; Parameters such as decay) better and bending property is bad, generally be used for inner wire, as be used to connect PC inner SAS and SATA cable products.Bending property is better to line structure wire rod high frequency performance is bad for strand, is usually used in traditional consumption property External cable product, and as using at HDMI, Displayport is on the cable products such as DiiVA.Because of the External cable product because of the higher bending property of demand; So generally all adopt strand to the line structure wire rod; Yet twist relatively poor to the relative parallel line structure of high frequency performance of line structure wire rod; So have certain limitation, can't satisfy length transmission or the high requirement of transmission signals quality under same length transmission, so can't satisfy client or consumer demand.

Be with, need a kind of improved cable to overcome the deficiency of prior art.

[utility model content]

The purpose of the utility model is the cable that provides a kind of high frequency and bending property all good.

To achieve these goals; The utility model adopts following technical scheme: a kind of cable; It comprises: one that is positioned at its center be used for transmission signals wire rod, be coated on the outer protective layer of wire rod and be coated on the outer serving of protective layer; Said wire rod comprises some leads that combine, and said wire rod two ends are for twisting line structure, and the mid portion of said wire rod is the parallel line structure.

To achieve these goals; The utility model can also adopt following technical scheme: a kind of cable that is connected to electric connector; It comprises: one that is positioned at its center be used for transmission signals wire rod, be coated on the outer protective layer of wire rod and be coated on the outer serving of protective layer; Said wire rod comprises some leads that combine; The link that said wire rod is connected with electric connector is for twisting line structure, and the mid portion of said wire rod is the parallel line structure, and the stress of said electric connector rear end is eliminated the periphery that piece is formed at the link of said wire rod.

Compared with prior art; The advantage of the utility model cable is: the wire rod in the cable has adopted segment design; With the wire rod link that electric connector stress elimination piece combines bending property is had relatively high expectations; Therefore the lead in the link of wire rod twists together in twos and forms strand to line structure in the cable; And wire rod mid portion less demanding to bending property in the cable, so the some leads in the wire rod mid portion form to walk abreast and combine and form the parallel line structure, like this; When fully guaranteeing the micro coaxial cable connector assembly bending property, also promoted the high frequency performance of product greatly, thereby broken through product industry maximum length limitation and satisfy faster high-frequency transmission rate requirement.

Fig. 3 is the part isometric exploded view that an end of cable shown in Figure 2 is connected to connector.

[embodiment]

See also Fig. 1 to 3; The utility model cable 1, it comprise be positioned at its center extend along longitudinally one be used for transmission signals wire rod 10, be coated on protective layer 12 outside the wire rod 10, be coated on the braid (not shown) outside the protective layer 12 and be coated on the serving 13 outside the braid.Wire rod 10 comprises the some leads that combine 11.The two ends of wire rod 10 are for being connected to the link 100 that connects electric connector 2, and the some leads 11 in the link 100 twist together in twos, and the link 100 of wire rod 10 is for twisting line structure like this.Some leads 11 parallel combining in the mid portion 102 of wire rod 10, like this, the mid portion 102 of wire rod 10 is the parallel line structure.Like this, wire rod 10 two ends 100 have good bending property, the mid portion 102 of wire rod 10 then has good high frequency performance.Protective layer 12 is a layer of non-woven fabric, and its spiral is wound in the periphery of lead 11, because the pliability of nonwoven fabrics 12, nonwoven fabrics 12 can cushion the external force that lead 11 receives.

See also Fig. 2 and Fig. 3, cable 1 is connected to electric connector 2, and electric connector 2 can be connectors such as HDMI, Displayport.The stress that is positioned at electric connector 2 rear ends is eliminated the periphery that piece 21 is formed at cable 1 wire rod 10 links 100; Because wire rod 10 links 100 are for twisting line structure; When electric connector 2 docked the needs bending with butt connector (not shown), cable 1 can be satisfied the demand.

Wire rod 10 in the utility model cable 1 has adopted segment design; Have relatively high expectations with 100 pairs of bending properties of wire rod 10 links that electric connector 2 stress elimination piece 21 combines; Therefore the lead 11 in the link 100 of wire rod 10 twists together in twos and forms strand to line structure in the cable 1; And cable 1 interior 102 pairs of bending properties of wire rod 10 mid portions is less demanding; So the some leads 11 in wire rod 10 mid portions 102 form parallel combining and form the parallel line structure; Like this, when fully guaranteeing the micro coaxial cable connector assembly bending property, also promoted the high frequency performance of product greatly, thereby broken through product industry maximum length limitation and satisfy faster high-frequency transmission rate requirement.
