Description

Technical Field

[0001] The utility model belongs to the technical field of shielded wire production, and in particular relates to a shielded wire production heat shrink device. Background Art

[0002] Shielded cable is a transmission line specially designed to prevent electromagnetic interference. It reduces the impact of external electromagnetic fields on power or communication lines through its metal shielding layer. Shielded cable usually includes an inner conductor and an outer metal shielding layer. This shielding layer can be a metal braided layer or a metal foil layer, which is used for reflection, absorption and skin collection effect, thereby improving electromagnetic compatibility. The working principle of shielded cable is mainly to use the metal shielding layer to reflect and absorb external electromagnetic waves, and to use the skin effect to limit the interference current to the surface of the shielding layer, thereby protecting the internal wires from interference. In order to ensure the shielding effect, the shielding layer of the shielded cable should be properly grounded. Under normal circumstances, the shielding layer is not allowed to be grounded at multiple points, because there may be a potential difference between different grounding points, which will form a circulation in the shielding layer. Ring current may introduce interference. Shielded wires are widely used in situations that require higher signal quality, such as high-precision measuring equipment, connecting wires of sensitive electronic equipment, and cables used in environments with strong electromagnetic interference. When using shielded wires, you need to pay attention to the grounding method and length control. Too long shielded wires may introduce additional induced current and affect the shielding effect. At the same time, you need to ensure the integrity of the shielding layer. A damaged shielding layer will reduce the shielding effect. In general, shielded wires are important components in the fields of electronics and communications. They use special designs to improve the system's anti-interference ability and ensure accurate signal transmission. When designing, installing and using shielded wires, correct grounding and usage are essential to maximize their effectiveness, and heat shrinkage is required during the production of shielded wires.

However, the above-mentioned heat shrink device for the production of shielded wires is not designed with a reeling device. After the heat shrinking process of the shielded wire is completed, the shielded wire needs to be reeled and stored in order to store and transport the shielded wire.
