Description

Technical Field

[0001] The invention relates to a wire material processing technology, in particular to a cable end shielding processing method and a device thereof. Background Art

[0002] When the cable wires currently used in network, telecommunication, power connection, etc. are connected to the connector and other components at their ends, it is often necessary to peel off the coating on the outside of the wire before electrical connection can be made. In order to improve the anti-interference performance of general cables, a shielding layer such as a braided material is coated on the outside of the internal core wire, which can reduce radiation, prevent signal leakage or attenuation, and other shielding effects, so that the wire has a higher transmission rate. Therefore, in the processing of the cable end, the part of the shielding layer exposed outside the end is not completely cut off. Instead, the exposed part is retained and trimmed, and then connected to the metal shell of the connector by welding, riveting, etc., so that the finished product has better anti-EMI performance and higher transmission rate.

[0003] However, in order to trim the exposed part of the shielding layer, the traditional processing method is mostly manual. In particular, in the trimming operation, a small section of the outer sheath of the cable is first peeled off to expose the shielding layer, and then the exposed shielding layer is folded back in a diffused manner to cover the end edge of the sheath, and finally copper foil is wrapped for subsequent processing. When the exposed shielding layer is folded back in a diffused manner to cover the end edge of the sheath, not only is the processing time-consuming, labor-intensive and inconvenient, but also the uniformity of the folded braided shielding layer cannot be ensured due to manual operation, which is also easy to affect the shielding effect of the final product. Summary of the invention

[0004] The main purpose of the present invention is to provide a cable end shielding processing method and device to overcome the defects in the prior art that manual operation cannot ensure the uniformity of the folding of the braided shielding layer, affecting the shielding effect of the final product, and the time-consuming, labor-intensive and inconvenient manual processing.

[0062] Please refer to the following detailed description and drawings of the present invention. However, the drawings are only provided for reference and illustration and are not intended to limit the present invention.

[0063] See also Figure 1 and Figure 2 , are respectively a flowchart of the processing method of the present invention and a three-dimensional exploded view of the processing device of the present invention. The present invention provides a cable end shielding processing method and device, which are used for shielding processing of a cable 1 end. Figure 1 Step S1 and Figure 3As shown, the cable 1 mainly comprises a plurality of core wires 10, a shielding layer 11 covering the outside of each core wire 10, and a covering layer 12 covering the outside of the shielding layer 11. The shielding layer 11 can be woven from metal wires, and each core wire 10 can be first covered in the copper foil layer 100 through a copper foil layer 100, and then the shielding layer 11 covers the outside of the copper foil layer 100.

[0064] like Figure 1 Step S2 and Figure 4 As shown, a surplus material segment 120 is cut on the coating layer 12 at one end of the cable 1, and the surplus material segment 120 is pulled out of the cable 1 at one end by a distance d, so as to expose the shielding layer 11 in the coating layer 12 at the distance d. The surplus material segment 120 can be cut by general tools, mainly to cut the coating layer 12 to avoid damaging the shielding layer 11, and at the same time, the cut surplus material segment 120 is peeled off but still retained on the shielding layer 11 of the cable 1, so that the shielding layer 11 is exposed at the pulled distance d.

[0065] Please see again Figure 2 As shown, the processing device 2 of the present invention comprises at least a base 20, a fixed tool holder 21, and a movable tool holder 22. The base 20 is used to carry the fixed tool holder 21 and the movable tool holder 22, and can achieve the purpose of automation by controlling a driving unit such as a cylinder. In the embodiment of the present invention, the base 20 is generally an "L"-shaped body (composed of two L-shaped plates spaced apart in parallel), and a knife arm 200 for mounting the fixed tool holder 21 is erected at the upper part of the "L" shape, and a track 201 is provided on the inner side of the lower part of the "L" shape. The movable tool holder 22 cooperates with the track 201 and is movably arranged on the base 20, so that the movable tool holder 22 can move in a straight line direction on the base 20 along the track 201. In addition, the processing device 2 further includes a clamping arm 23, which is disposed outside the fixed knife seat 21 on the other side of the movable knife seat 22 and has a first clamping portion 230 and a second clamping portion 231. The first and second clamping portions 230 and 231 can provide clamping and positioning for the processed cable 1. The base 20 can further be provided with an extension plate 202 on the knife arm 200, so that the clamping arm 23 is assembled below the extension plate 202.

[0066] For further information, please also refer to Figure 1 , Figure 5 and Figure 6As shown, the fixed knife seat 21 is provided with a fixed knife plate 210, and a knife hole 211 is provided on the fixed knife plate 210, and the movable knife seat 22 has a knife holder 220 matched with the track 201, and a reverse thrust sleeve 221 and a knife 222 matched with the reverse thrust sleeve 221 are provided on the knife holder 220, and the knife 222 has a blade 223 corresponding to the knife hole 211. The reverse thrust sleeve 221 can be pushed or withdrawn toward the fixed knife plate 21 by a reverse thrust unit 24, and the knife 222 can be pushed or withdrawn toward the knife hole by a feed unit 25, and the reverse thrust unit 24 and the feed unit 25 can be a pneumatic cylinder or a hydraulic cylinder. Therefore, as Figure 5 As shown, Figure 4 The end of the cable 1 can pass through the knife hole 211 so that the remaining material segment 120 can enter the reverse thrust sleeve 221. In order to allow the cable 1 to enter smoothly, the knife 222 can be pushed toward the fixed knife plate 21 so that the remaining material segment 120 can enter the reverse thrust sleeve 221 in sequence. Figure 6 shown.

[0067] like Figure 7 As shown, in order to facilitate the implementation of subsequent steps, the processing device 2 can first withdraw the tool 222 backwards during implementation.

[0068] Please see again Figure 1 Step S3 and Figure 8 As shown, the remaining material section 120 of the cable 1 is pushed back to Figure 6 The shielding layer 11 is exposed on the spacing d in the form of an annular raised portion 110; wherein, the excess material segment 120 can be pushed back to the spacing d by pushing the reverse push sleeve 221 of the processing device 2 toward the fixed knife plate 210, and since the cable 1 can also be clamped and positioned by the clamping arm 23, the exposed shielding layer 11 can be pushed on both sides by the external force, so that the raised portion 110 can be naturally formed to form a uniform distribution.

[0069] Please see again Figure 1 Step S4 and Fig. 9 As shown, the bulge 110 is cut off along the annular outer periphery, so that the bulge 110 is divided into a diffusion portion 111 remaining on the shielding layer 11 and a material removal portion 112 remaining in the residual material section 120; wherein, the bulge 110 of the cable 1 can be cut by the blade 223 of the processing device 2 facing the knife hole 211. It is worth mentioning that the bulge of the bulge 110 must exceed the knife hole 211 to facilitate cutting by the blade 223; and the bulge 110 can be calculated by the above-mentioned spacing d.

[0070] Finally, if Figure 1 Step S5 and Fig.10As shown, after the excess material section 120 and the removed material portion 112 are removed from the cable 1, a more evenly distributed diffusion portion 111 can be formed on the shielding layer 11 at the end of the cable 1; Fig.11 As shown, the diffusion portion 111 is folded back outside the end of the coating layer 12 of the cable 1 to complete the finished product.

[0071] Therefore, through the above-mentioned structural composition, the cable end shielding processing method and device of the present invention can be obtained.

[0072] Of course, the present invention may have many other embodiments. Without departing from the spirit and essence of the present invention, technicians familiar with the field may make various corresponding changes and deformations based on the present invention, but these corresponding changes and deformations should all fall within the scope of protection of the claims of the present invention.
