Problems solved by technology

[0009] However, if the above process is used to rivet the ultra-thin coaxial cable and the connector terminal, the precision of the connection between the connector terminal and the coaxial cable is not high, and the mechanical connection of the line is not reliable, which affects the transmission of electrical signals

[0047] Most of the ultra-thin coaxial cables are composed of multi-layer wires, including outer skin layer, shielding wire layer, insulator layer and core wire conductor layer from outside to inside. The first embodiment of the processing method of welding the ultra-thin coaxial cable and the connector (including the flexible circuit board FPC / circuit board PCB) of the present invention includes the following steps in sequence:

[0048] (1). According to the spacing requirements of the connectors to be connected, use tape to glue the coaxial cables into equal-spaced cables with a spacing of 0.2mm to 1.5mm;

[0049] (2). Cut the glued coaxial cable into the desired length of the product;

[0050] (3). Using CO 2 Cutting off the outer cortex of the coaxial line described in step (2) by laser;

[0051] (4). Use a moving machine to remove the outer skin layer cut off in step (3) to expose the shielding wire layer;

[0052] (5). Use pulse heating or laser heating at a high tempe...

Abstract

The invention discloses a processing method for connecting a micro coaxial cable and a connector, which comprises the following steps: firstly cutting an entire column of coaxial flat cable according to the required length of the product; cutting off an outer skin layer of the coaxial cable by laser and moving away the outer skin layer which is cut off so as to expose a shielding cable layer; welding a copper grounding strap plated with tin and the exposed shielding cable layer at above 230 DEG C; cutting off or cutting the shielding cable layer welded with the copper grounding strap by laser and moving away the cut shielding cable layer which is cut off so as to expose an insulator layer; cutting off the exposed insulator layer by laser and moving the cut insulator layer away so as to expose a core cable conductor; plating a layer of tin on the surface of the exposed core cable conductor; cutting off the copper grounding strap and the core cable conductor according to connecting requirements of the connector to be connected; and finally welding the core cable conductor and a terminal of the connector to be connected at above 230 DEG C. The invention has high manufacturing precision and guaranteed quality of the finished product.

Description

technical field [0001] The invention relates to a processing method, in particular to a processing method for connecting a coaxial cable with a connector. Background technique [0002] Most of the ultra-fine coaxial cables are composed of multi-layer wire bodies, which include the outer skin layer, shielded wire layer, insulator layer and core wire conductor layer from outside to inside. Among them, the shielded wire layer is mainly used as the core wire conductor layer to guide the signal. To prevent the generation of electromagnetic interference. This kind of wire is a whole coaxial cable when it is produced in the factory, so the wire end must be stripped and cut to expose the shielding wire layer and the core wire conductor layer to be welded to the ground plate and the connector terminal respectively. [0003] Chinese patent publication No. 1328364A discloses a processing method for connecting an ultra-thin coaxial cable to a connector terminal, which includes the foll...
