Description

Technical Field

[0001] The utility model relates to the technical field of high-frequency cables, in particular to a parallel wiring fixture for multi-core cables. Background Art

[0002] The cable core stranding production device is a device used to twist multiple conductors into one during the cable production process. The stranding drum is an important part of the cable core stranding production device.

[0003] The existing parallel wiring jigs for multi-core cables are generally designed to improve the problem that the stranding drum in the existing structure easily causes the bare stranded wire to lack a lubrication mechanism when passing through the stranding drum. Under the long-term friction of the bare stranded wire, the stranding drum is easy to damage the bare stranded wire, affecting the quality of the cable, and even causing the bare stranded wire to break and affect the processing of the cable core. For example, the authorized Chinese patent CN217847544U discloses a multi-strand cable core stranded wire production device, which can be used in conjunction with structures such as a base, a support roller, a stranding machine drum, a stranding drum, a wire hole, a groove, a lubrication mechanism, a ball, a spring, an oil outlet channel, an oil injection channel, an oil injection nozzle, a hub, a hub port and a connecting rod. A lubrication mechanism can be set in the wire hole. When the bare stranded wire passes through the wire hole, the ball is driven to rotate to bring the lubricating oil inside the groove out of the oil outlet channel to lubricate the bare stranded wire, thereby reducing the wear of the bare stranded wire at the wire hole. At the same time, the lubricating oil can reduce the friction of the cable core in subsequent processing.

[0004] However, when the multi-core cable parallel wiring jig in the above-cited document is used for the production and processing of multi-core cables, the outer diameter of the multi-core cable is greatly affected by the internal and external environment, and the outer diameter size fluctuates greatly during cable processing, and it is impossible to make the outer diameter of the same processed product basically consistent. At the same time, in the processing of multiple batches of similar products, various electrical performance tests, the product performance cannot be kept consistent. Therefore, a multi-core cable parallel wiring jig is needed to solve the above problems. Utility Model Content

[0009] Furthermore, a connected wire core through hole is opened between the No. 1 mold body and the No. 2 mold body on the opposite side, and the number of the wire core through holes is multiple and arranged at equal intervals.

[0031] In this embodiment, the efficient paralleling mold 600 is a structure used to achieve the purpose of paralleling production in the cable production stage.

[0032] like Figure 1 , Figure 2 and Figure 3As shown, the high-efficiency paralleling mold 600 includes a mold body 601, a clamping portion 602, a mold body 603, a first plug rod 606 and a second plug rod 608; one side of the mold body 601 is fixedly connected to one end of the mold 4, one side of the clamping portion 602 is fixedly connected to the side of the mold body 601 away from the mold 4, and the number of the clamping portions 602 is two and they are distributed in a mirror-symmetrical manner; the second mold body 603 is opened on the side close to the first mold body 601 A clamping groove 604 is provided for the clamping portion 602 to fit and clamp. The No. 1 mold body 601 is clamped in the clamping groove 604 on the No. 2 mold body 603 through the clamping portion 602.
