Description

TECHNICAL FIELD

[0001] The utility model relates to the field of connector, concretely relates to a cable assembly. BACKGROUND

[0002] In the existing Mini Fakra cable processing, the traditional braid turning process is adopted, that is, the wire clamp is first riveted and pressed on the braided wire, the braided wire not pressed by the wire clamp is covered on the surface of the wire clamp through 180-degree turning, and finally the braided layer and the outer conductor are fixed. The assembly mode of "braid turning" can ensure good contact between the braided layer and the outer conductor, thereby forming good electrical connection. The cable processed by the "braid turning" mode often forms a region without braided coverage, and it is difficult to realize the continuity of the shielding effect. The usual solution is to add a support ring in the region without braided coverage, but the support ring and the outer conductor and the cable may be in a loose fitting state, which cannot well protect the cable and is not conducive to improving the integrity of the signal.

[0003] In view of this, it is necessary to propose a new structure to improve the above-mentioned defects. CONTENT OF THE UTILITY MODEL

[0004] The utility model provides a kind of cable assembly, can form electrical connection between cable and outer conductor, realize the shielding protection of outer conductor to cable assembly, two-section direct connection sleeve structure can effectively enhance the continuity of cable assembly shielding, guarantee the transmission of high-frequency signal. The purpose of the utility model is achieved by the following scheme:

[0005] A kind of cable assembly, including cable, outer conductor, sleeve, the cable includes first subsection, second subsection, third subsection, the sleeve is by first circular tube structure, second circular tube structure, connecting part is composed, the second circular tube structure of the sleeve is fixed on the outer surface of the third subsection of the cable, and the outer conductor is fixed to the outside of the sleeve;Wherein, the first circular tube structure of the sleeve and the outer conductor are fixed by the way of dotting, the second circular tube structure of the sleeve and the outer conductor are fixed by the way of riveting, and the bridge effect of the sleeve makes the stable connection between the outer conductor and the cable. In "braid turning" processing, there is no connecting structure between support ring and wire clamp, and the support ring and the outer conductor and the cable are also in loose fitting, which is not conducive to the transmission of high-frequency signal, reduces the improvement space of high-frequency performance of cable assembly, and also reduces the support performance of cable assembly. In the improved cable assembly, the first circular tube structure and the second circular tube structure of the sleeve are connected by the connecting part, the sleeve can form better sealing blocking effect to the subsection of the cable, better resist electromagnetic interference, and improve the integrity of signal. The sleeve is fixed with the outer conductor and the cable respectively, the weak connection between the support ring and the cable in the original "braid turning" processing is cancelled, a tight connection is formed between the outer conductor, the sleeve and the cable, and the high-frequency performance of product is improved.

[0006] Preferably, the cable is a coaxial cable, the first segment is an inner conductor of the cable, the second segment is in order from inside to outside an inner conductor and an insulation layer of the cable, the third segment is in order from inside to outside an inner conductor, an insulation layer and a braided layer of the cable, and the first and second tubular structures of the sleeve respectively cover the outer surfaces of the second and third segments of the cable. Compared with the "wire clamp + support ring" structure in "re-braiding", the sleeve is integrally formed and covers the outer surface of the cable, which can maintain the continuity of the overall shielding effect of the cable assembly.

[0007] Preferably, the outer conductor is fixed between the first tubular structure of the sleeve and the second tubular structure of the sleeve by a laser welding process. By fixing the outer conductor and the tubular structure of the sleeve by a laser welding process, a stable electrical connection can be formed between the sleeve and the outer conductor.

[0008] Preferably, the sleeve is made by a stamping process, and the third segment of the cable is fixed to the second tubular structure of the sleeve by riveting. The sleeve is integrally formed, and after the second tubular structure of the sleeve is fixed to the third segment of the cable, the first tubular structure does not need to be fixed to the second segment, and the sleeve and the cable can maintain good stability. In the "re-braiding" process, in order to avoid missing riveting pressure of the braided wire, the riveting interface needs to be designed as a zigzag shape. When the sleeve structure is directly riveted on the uncombed braided layer, the riveting interface does not need to be designed as a zigzag shape and can effectively avoid missing riveting pressure.

[0009] Preferably, the sleeve is made by a stretching process, and after the sleeve is horizontally fitted to the cable, the second tubular structure of the sleeve is fixed to the third segment of the cable by a laser welding process. The inner diameter of the first tubular structure of the sleeve is greater than the outer diameter of the second segment of the cable, and the inner diameter of the second tubular structure is greater than the outer diameter of the third segment, so as to ensure that the sleeve is smoothly inserted horizontally. In the processing process, the cable assembly using the sleeve structure does not need to comb the braided layer into braided wires, so even if the sleeve rubs against the braided layer during insertion, it will not cause the braided layer to be reversed.

[0010] Preferably, the sleeve is made by a turning process, and after the sleeve is horizontally fitted to the cable, the second tubular structure of the sleeve is fixed to the third segment of the cable by a laser welding process.

[0011] Preferably, the cable assembly further comprises a center terminal and an insulation base, the center terminal is fixed to the first segment of the cable by dotting, and the insulation base is arranged on the outer periphery of the center terminal and is fixed to the center terminal by riveting.

[0012] The cable assembly has the advantages that the sleeve is integrally formed, can protect the area of the cable without the braided layer, avoids the interference signal from entering the inner layer of the cable, realizes the continuity of the shielding effect, and guarantees the integrity of the signal; on the other hand, the cable and the outer conductor are fixed through the cable, the sleeve and the outer conductor, and the cable and the outer conductor form a strong electrical connection, and the outer conductor can better play a shielding protection role.
