Description
Technical Field
The invention relates to the technical field of manufacturing processes of video signal converters, in particular to a connecting wire of a video signal converter and a processing method thereof.
Background
There are currently internationally a number of video signal transmission formats, such as: CVBS, VGA, DP, DVI, HDMI, USB, etc., wherein CVBS, VGA are transmission formats of analog signals, and DP, DVI, HDMI, USB are transmission formats of digital signals, which have been widely used in various devices and home appliances.
Due to different signal transmission formats, incompatibility of signal transmission between devices and electric appliances using different signal formats is caused, for example, images and videos downloaded by a computer are transmitted to a television set with only an HDMI interface for watching through a USB interface on the computer, and the watching is impossible. There is a need for a video signal converter: and converting the USB signal output by the computer into an HDMI signal format.
Due to the many signal formats, the need to convert between a large number of different format signals arises, such as: the USB signal is converted into HDMI signal, the USB signal is converted into VGA signal, the HDMI signal is converted into VGA signal, the DP signal is converted into HDMI signal, the VGA signal is converted into HDMI signal, and the like.
In these products, there is a very important technical index, namely: the technical index of electromagnetic interference (EMI) mainly describes the interference of electronic and electric products to the outside under normal work, and the index has two types of conduction interference and radiation interference, wherein the radiation interference is particularly important. The radiation interference means that signals in electronic and electric products are transmitted to the surrounding space in the form of electromagnetic waves, and interfere with other electronic and electric equipment in the surrounding space, so that the normal work of the electronic and electric equipment is influenced, and the other equipment can be out of order or even damaged in serious cases. Therefore, how to reduce the electromagnetic interference is a particularly important issue when developing and designing electronic and electric products.
When solving the problem of electromagnetic interference of a video signal converter, firstly, how to reduce the outward radiation of signals in the product when the signals are transmitted in a cable or how to reduce the outward radiation of the transmitted signals by improving the shielding performance of a connecting line is to be solved.
Since the connection line in the converter is composed of three parts: one section is connecting cable, and connecting cable includes inside heart yearn, weaves at the outside weaving layer that plays the shielding effect of heart yearn and sets up the crust that plays the guard action outside weaving layer, and wherein the weaving layer comprises 16 groups and 8 copper wires of every group, and another section is various joints, and the interlude is the welded part that the heart yearn of joint and connecting cable corresponds. The shielding performance of the connection line has four determinants: the shielding performance of the connecting cable, the shielding performance of the connector shell, the copper foil coated outside the welding part (middle part) corresponding to the connector and the core wire, and the connection of the copper foil coated outside the welding part corresponding to the shielding layer and the core wire of the cable are well solved by the first three determining factors, and most importantly, the mutual connection of the copper foil coated outside the welding part corresponding to the shielding layer and the core wire of the cable is difficult to realize, so that the shielding performance of the whole cable can be ensured not only by ensuring the reliable conduction performance of an electric appliance, but also ensuring that the gap after the connection is less than 0.15 mm.
The connection between the joint shell and the copper foil coated outside the middle part is better realized by only adopting self-adhesive copper foil to coat the joint shell and welding to connect the joint shell and the copper foil in a seamless way, while the shielding of the connecting cable is realized by the braided layer of the connecting cable, the shielding performance of the braided layer is very good, but how to realize the connection between the cable shielding layer (namely, the braided layer) and the copper foil coated outside the middle part in a seamless way is the most critical.
As shown in fig. 1, the method for processing the connection lines of the currently used video signal converter includes the following steps:
(1) firstly, removing the outer skin of the end part of the connecting cable to expose the braided layer of the end part of the connecting cable;
(2) reversely brushing the braided wires of the braided layer exposed at the end part of the connecting cable to expose the core wires of the end part of the connecting cable;
(3) welding the core wire of the connecting cable with the joint;
(4) injecting an inner mold at the welding position of the core wire of the connecting cable and the joint;
(5) coating self-adhesive copper foil on the outer part of the inner die;
(6) reversely brushing the woven wires connected with the end part of the cable back and covering the woven wires outside the self-adhesive copper foil;
(7) welding the self-adhesive copper foil and the weaving wire together;
(8) and welding the self-adhesive copper foil and the joint shell together.
In the above processing method, the braided wire in the connecting cable is covered on the self-adhesive copper foil outside the inner mold of the middle part, and then the braided wire and the self-adhesive copper foil are welded with each other, so that the purpose of connecting the shielding layer of the connecting cable and the shielding layer of the middle part is achieved.
The processing method of the connecting line has the following defects: 1) When the inner mold is injected, the glue sealing position of the glue material is on the core wire of the connecting cable, so that the glue material is easily flushed to the inside of the connecting cable, and the appearance is poor; 2) when the inner mold is injected, the braided wires which are brushed reversely for the first time are easily broken by the mold, so that the number of the braided wires welded with the copper foil is reduced, the welded gap is enlarged, the appearance quality of the connecting wire is influenced, and the shielding performance of the connecting wire is reduced; 3) after the inner mold is injected, when the copper wire is brushed on the copper foil in a reverse mode again, the copper wire is not easy to brush in a reverse mode evenly, gaps are enlarged, the appearance quality of the connecting wire is affected, and the shielding performance of the connecting wire is reduced; 4) the copper wire is reversely brushed on the copper foil and cannot be tightly attached to the copper foil, so that the welding is very difficult, and the production efficiency is influenced; 5) when the weaving wire and the copper foil are welded, the welding time needs to be accurately mastered, otherwise, one side of the weaving wire is easily welded, the welding time is long when the other side of the weaving wire is welded, and the welded weaving wire is detached, so that the production efficiency is influenced.
