Description

Improved transmission conductive wire shielding structure that blocks electromagnetic wave interference

The utility model relates to a transmission conductive wire shielding structure that blocks itself and external environmental electromagnetic wave (EMI) interference, in particular to an improved electromagnetic wave blocking ( EMI) interference transmission conductive wire shielding structure.

Generally, the existing cable structure, as shown in Fig. 1, has two electric wires 100, the surface of the two electric wires 100 is coated with an insulating plastic sleeve 101, and the insulating plastic sleeve 101 has a copper wire. Conductive wire 102, and there is a filler 200 between the two wires 100, the filler 200 is filled between the two wires 100, and the two wires 100 are completely covered to form a circular shape, so that Aluminum foil or copper foil Mylar 300 is easy to wrap on its surface. After fixing the two wires 100 together, the mesh cover 400 woven from metal wires is used to cover its periphery, and finally, through injection molding. , so that the plastic 500 is covered on its surface. When this structure is in use, the aluminum foil or copper foil Mylar 300 must be wound first before the two wires 100 can be fixed together. The mesh cover 400 is woven by wire weaving, so it is very time-consuming and expensive to manufacture and assemble. At the same time, due to the use of wire weaving, the weight is heavy, and the corresponding transportation cost is also greatly increased.

The main purpose of the utility model is to provide an improved transmission conductive wire shielding structure that blocks the interference of itself and external environmental electromagnetic waves (EMI).

The utility model is provided with a transmission conductive wire, which is used to transmit electronic signals or connect with a power supply, and the surface of the transmission conductive wire is covered with a plastic insulator, and the surface of the plastic insulator is wound with a shielding electromagnetic wave (EMI) Textile fabric; the transmission conductive wire can not only effectively block the electromagnetic wave (EMI) interference generated by itself and the external environment through the textile fabric, but also can be tightly fixed together by winding it, so that the insulating coating on the surface During injection molding, the transmission conductive wire will not be scattered and has a shape-setting function.

The effect of the utility model is: due to the simple structure, the working time can be greatly shortened, the production efficiency can be increased, and the cost price of the above-mentioned textile is relatively low, and the weight of the overall cable product can be reduced, and the transportation cost is relatively reduced. The material is more flexible, easy to bend and not broken, which increases the market competitiveness.

Below is the description of the accompanying drawings of the utility model:

Figure 1 is a schematic diagram of the existing structure.

Fig. 2 is a schematic cross-sectional view of an embodiment of the utility model.

Below in conjunction with accompanying drawing, the utility model is described in detail.

The utility model is an improved transmission conductive wire shielding structure for blocking electromagnetic wave (EMI) interference. The transmission conductive wire can be a general electric wire, a coaxial cable UHF (above 100MBz) signal transmission line, etc. Fig. 2 is an embodiment of the present utility model, and this structure is provided with the transmission conductive line 20 (in this embodiment is the copper wire) that is separated by the non-conductor 10 (in this embodiment is the casing made of plastic), The transmission conductive wire 20 is used to transmit electronic signals or connect with a power supply. There is a filler 13 between the two wires 10, and the surface of the transmission conductive wire 20 is wound with a shielding electromagnetic wave (EMI) made of special material. ) The textile 30 that interferes with the function is a textile mixed with various metal materials in this embodiment (those who are familiar with the art can still replace it with other elements), the textile 30 can not only effectively block the transmission of the conductive wire 20 The generated electromagnetic wave (EMI) interferes, and the conductive thread 20 and the non-conductive body 10 can be tightly fixed together, and the surface of the textile 30 is covered with an injection-molded covering body 40, and the covering body 40 is Made of plastic, in this way, the conductive thread 20 will not scatter when the covering body 40 is injection molded. At the same time, because the textile winding method is used instead of the traditional metal wire weaving method, it can effectively block electromagnetic wave (EMI) interference The shielding effect not only reduces working time and increases production efficiency, but also greatly saves relative transportation costs due to its lighter weight. At the same time, because the textile has better softness, it is easy to bend and will not break, which increases the market. competitive advantage.
