Horizontally twisted cable with vertical package integrated mold

Abstract

The invention discloses a longitudinal wrapping integrated mold for horizontal twisted cables, which comprises a fixing seat, and a plurality of sizing dies are pierced in the fixing seat, and one end of the sizing die is provided with a protruding hole protruding from the fixing seat The connection part, the outer side of the connection part is covered with a metal connection sleeve, the metal connection sleeve is pierced with an aluminum foil longitudinal wrapping mold, and the aluminum foil longitudinal wrapping mold is provided with a threading pipe. On the one hand, the longitudinal wrapping integrated mold for horizontal twisted cables of the present invention can simultaneously coat multiple twisted wires with aluminum foil, reduce the process of wrapping aluminum foil alone, improve production efficiency, and reduce labor costs; on the other hand, through aluminum foil The stranded wire covered by the longitudinal die is covered again by the sizing die to ensure that the aluminum foil will not turn over, wrinkle, and expose the core wire, etc., making the aluminum foil covering more round, and, through The fixed base fixes the position of the sizing die together, ensuring the outlet position of each pair of twisted wires after covering, which is convenient for the subsequent stranding process.

Description

technical field [0001] The invention relates to the field of communication cable production and manufacturing, in particular to a longitudinal wrapping integrated mold for horizontally twisted cables. Background technique [0002] With the development of 5G communication networks, the demand for UHF LAN connection components has increased, and the increase in network speed means that the operating frequency has increased and interference is more likely to occur. Therefore, each pair of individually shielded horizontal twisted-pair shielded cables is used. Refer to figure 1 As shown, taking the twisted pair as a unit, the outside of each pair of twisted pairs needs to be coated with a layer of aluminum foil to ensure the stability of signal transmission and improve the anti-interference ability; the stability of each aluminum foil coating directly affects The signal transmission of the finished cable has a great influence on the characteristic impedance, attenuation, return l...

AI Technical Summary

Problems solved by technology

[0004] (1) Each wire pair is individually wrapped with aluminum foil, and then stranded as a whole to form a semi-finished product. This method has low production efficiency, requires production equipment and increases labor costs for production.

[0005] (2) At the same time as the cable core is twisted, each pair of wires is longitudinally wrapped with aluminum foil, and after passing through a separate sizing mold, it is stranded into a semi-finished product. A large amount of aluminum powder will accumulate below the wires. Since there is only one sizing die for each pair of wires to form and fix the aluminum foil, it is impossible to guarantee the position of the twisted wires covered with aluminum foil relative to the cable stranding machine. When twisting the machine, there will be problems such as aluminum foil wrinkling, turning over, and lax covering, which will have a great impact on the shielding of the finished cable. Moreover, each pair of twisted-pair wires covered by a separate sizing mold has an opening The direction of the twisted wires is different, which is easy to cause crosstalk between adjacent pairs of twisted wires
