Description

Jumper connectors for noise reduction

technical field

The utility model relates to a jumper connector which can reduce interference, but refers to the improvement of the structure of the jumper adapter plug which can be used to facilitate the connection of cables with network cards, modems, IP sharers, hubs and telephone adapter boxes. .

Background technique

Press, when any electronic product is in use, it will produce electromagnetic wave interference (Electromagnetic Interference, EMI) and noise (Noise) interference. Therefore, the design and manufacture of various electronic products and components must achieve a certain degree of electromagnetic compatibility. Sexual norms. However, the existing 8pin cable used in network connection will also generate an electromagnetic field when the current passes through the internal copper core wires, and interfere with other surrounding copper core wires. Therefore, the wire manufacturer often uses twisted technology to offset the electromagnetic field interference To comply with common standard specifications (such as EIA/TIA 568A), and to achieve high transmission efficiency and prevent signal attenuation (Attenuation) and other effects.

However, refer to the common jumper adapter shown in Figure 9, which mainly provides 8pin cables to easily connect with network cards, modems (Modem), IP sharers, hubs (HUB) and telephone conversion boxes.

The copper core wires 30 are unfolded to align with the wire groove 102 according to the usage requirements, and after the cable cover 20 and the plug 10 are assembled, each copper core wire 30 is passed through the wire groove 102 for the terminals 103 to pierce to form a conductive connection. However, the structural design of the plug 10 and the cable sleeve 20 of the common jumper adapter often requires the cable to be stripped of a relatively long outer sheath, and the front section of the copper core wires is arranged in an untwisted state too long. As a result, the above-mentioned electromagnetic field interference and signal attenuation occur at the line end, thus affecting the actual transmission rate. Therefore, it can be seen that the structural design of the jumper adapter is very important.
