Flat mobile phone data line manufacturing process

Abstract

The invention relates to a flat mobile phone data line manufacturing process. The flat mobile phone data line manufacturing process comprises the following steps of: putting a wound copper wire core material in an electric power pay-off machine; squeezing molten high density polyethylene into a first machine head mold by a screw in a machine barrel of a first extruder, and coating the copper wirecore material with the molten high density polyethylene so as to form a high density polyethylene layer; squeezing molten TPEE (Thermoplastic Polyester Elastomer) into the first machine head mold by ascrew in a machine barrel of a second extruder, coating the high density polyethylene layer with the molten TPEE so as to form a TPEE layer, and then generating core wires; causing the core wires topass through a cooling and drying mechanism, and pulling the multiple core wires side by side to pass through a second machine head mold; squeezing molten TPE (Thermoplastic Elastomer) into a second machine head mold by a screw in a machine barrel of a third extruder, and coating the multiple core wires with the molten TPE so as to form a TPE layer, and then generating a data line; causing the data line to pass through the cooling and drying mechanism, a spark testing machine and a stored line tension bracket, and then rolling the data line by a take-up mechanism.

Description

technical field [0001] The invention relates to the technical field of data line production technology, in particular to a flat mobile phone data line manufacturing process. Background technique [0002] As we all know, data lines are wires that transmit signals. Among them, the HDMI data cable is a wire used to transmit high-definition multimedia video signals, and the USB data cable is used for connection and communication between a computer and an external device. [0003] The smallest unit in the data cable is the core wire. During the manufacturing process of the core wire, several copper monofilaments are first twisted into a copper wire core material, and the high-density polyethylene particles are melted by a screw extruder to form a viscous flow. state, by extruding and covering the core material to form a high-density polyethylene layer to make a core wire, the setting of the high-density polyethylene layer can achieve the purpose of insulating and protecting the ...

Problems solved by technology

[0005] However, the insulating outer layer of the above-mentioned core wire is covered with high-density polyethylene. Although it can play the role of wear resistance and insulation, the high-density polyethylene layer is easy to adhere to the TPE outer layer, especially in the production process. It is necessary to connect the front and rear two data lines together, the core wire and the TPE outer layer are adhered together, and cannot be effectively peeled off from each other, which makes it difficult to connect the front and rear data lines, resulting in low production and processing convenience, so there is a certain improvement place
