Embodiment Construction

[0029] The device for rapid vertical tinning of the shielding layer of a semi-flexible coaxial cable and the tinning method thereof according to the present invention will be described in conjunction with the accompanying drawings and embodiments.

[0030] The present invention is used for semi-flexible coaxial cable shield layer rapid vertical tinning equipment and tinning method thereof are based on the following mechanism:

[0031] First of all, regarding the air hole defects in the tin plating of the coaxial cable shielding layer, after repeated tests, it was found that these tiny air holes are formed at the moment when the cable leaves the tin bath. The reasons for the analysis are as follows:

[0032] The cables are pre-soaked with flux before entering the tin bath, and some of the flux penetrates the inside of the wire shield. The commonly used lead-free fluxes are basically composed of organic matter, and its main components are prone to generate a large amount of gas...

Abstract

The invention provides vertical tinning equipment for a semi-flexible coaxial cable shielding layer, which comprises a pay off machine and a wire-receiving machine for paying out and receiving wires, a tinning groove, a lower guide wheel positioned below the tinning groove and an upper guide wheel positioned above the tinning groove; and the tinning groove is arranged on a stand. The invention also provides a vertical tinning method for the semi-flexible coaxial cable shielding layer; the method is a two-step method rapid tinning process which comprises a pretreatment process and a vertical tinning process. The invention has the advantages that the vertical tinning equipment and the vertical tinning method are used to tin the semi-flexible coaxial cable shielding layer, shorten the residence time of a cable in the tinning groove and the immerging length in tin liquid, effectively solve the problems of air vents existing in the coaxial cable tinning process and insufficient adhesive force of a tin layer to a shielding net and improve the tinning quality; and simultaneously, a high tinning speed and the two-step method tinning process are adopted, so the production efficiency is improved and the waste of material head and tail of the cable are reduced.

Description

technical field [0001] The invention relates to the field of electronic product manufacturing, in particular to a vertical tinning device and a tinning method for the shielding layer of a semi-flexible coaxial cable. Background technique [0002] Coaxial cables (radio frequency signal lines) are widely used in various communication equipment, cable television and communication networks, and measurement and control equipment. It is mainly used to transmit various high-frequency sound and image signals. In order to ensure the reliable transmission of signals and improve the anti-interference ability, the coaxial cable generally consists of four parts, such as figure 1 As shown, 1a is the conductor core for transmitting signals, which is generally made of oxygen-free copper; 2a is the polymer protective layer sheathed outside the conductor core, which protects the core wire and maintains a certain strength and rigidity of the cable ; 3a is the shielding layer, which is genera...
