Description

MULTI-CONDUCTOR CABLE SHIELDING LAYER MOUNTING ASSEMBLY AND SIGNAL TRANSMISSION DEVICE

The utility model belongs to the field of signal transmission, and particularly to a multi-core cable shield layer mounting assembly and a signal transmission device.

Prior art

With the rapid changes in the railway industry, the demands are becoming higher on signal transmission capacity. Connectors for signal transmission having more core pins (called pins) and more corresponding cable cores connected to the pins are necessarily required for high signal transmission capacity. To meet this demand, multi-conductor cables are often used. The transmission of signals from multi-conductor cables requires higher reliability, intelligence and resistance to electromagnetic interference.

In order to prevent signal interference in multi-core cables, each cable core is currently covered with a shield layer, some of the pins are connected to the shield layers of the cable cores to ground the shield layers, so that the foreign interference signals can be effectively conducted to the ground to prevent the interference signals from entering the cables and interfering with the signal transmission of the cable cores. It can be seen that the aforementioned design method currently used increases the assembly time of the product, reduces the assembly efficiency and increases the cost of the product, and in order to meet the shielding requirements, the number of pins of core is decreased, making it impossible to connect more core pins to cable cores and reducing signal transmission capacity. Further, there is a multi-core cable and a signal connector in the prior art, in which the multi-core cable is provided with a main shield layer, and the shield layer is arranged around all the cable cores instead of that each of the cable cores is coated with a shielding layer. In this way, although the number of cable cores connected to the core pins is ensured and the signal transmission ability is improved, the grounding problem of the shield layers is difficult to solve, and therefore the signal interference problem cannot be solved.
