Embodiment Construction

[0022] The technical solution of the present invention will be explained more clearly and completely through the description of preferred embodiments of the present invention in conjunction with the accompanying drawings.

[0023] Such as figure 1 As shown, the preferred embodiment of the present invention is a gas injection device applied to a low-capacitance coaxial line with a lotus structure, including an extruder head 1 arranged on a fluoroplastic extruder, and the upper and lower ends of the extruder head 1 are open and placed A through accommodation chamber 10 is formed between the openings at both ends. The accommodation chamber 10 is vertically arranged. The molten plastic extruded from the head of the fluoroplastic extruder flows downward in the vertical direction in the extrusion head 1, so that the molten fluorine When the plastic is extruded, it is in a state of natural drooping, which can avoid deformation and internal collapse caused by gravity. The top of the ...

Abstract

The invention discloses a gas injection device applied to a lotus-root-shaped structure low-capacitance coaxial line. The device comprises an extruder head arranged on a fluoroplastic extruder, two ends of the extruder head are open, a penetrated accommodating cavity is formed between openings at the two ends, one end of the extruder head is provided with a forming mold for extruding an insulatingwire with a lotus-root-shaped insulating layer, the other end of the extruder head is provided with a gas injection mold for injecting a gas into the forming mold, and the gas injection mold is connected with an air pressure adjusting controller for supplying the gas. By using the device, air holes which are uniform in size and proper in proportion can be formed in the insulating wire so that capacitance stability of the low-capacitance insulating wire is improved, and a smaller insulation outer diameter is obtained under a condition that an equivalent dielectric constant is not changed.

Description

technical field [0001] The invention relates to a gas injection device applied to a low-capacitance coaxial line with a lotus structure, and belongs to the technical field of low-capacitance coaxial lines. Background technique [0002] Coaxial cable is a shielded and non-dispersive structure, generally a wire system composed of two coaxial cylindrical conductors, with an insulating layer between the inner and outer conductors. Usually the outer conductor of the coaxial line is grounded, and the electromagnetic field is limited between the inner and outer conductors, so the coaxial line basically has no radiation loss and is almost free from external signal interference. Common forms of coaxial cables mainly include low-capacitance high-impedance and high-capacitance low-impedance, among which low-capacitance coaxial cables are mainly used in signal transmission in electronic products such as mobile phones, industrial computers, televisions, and medical equipment. Equipment ...
