Description

Technical Field

[0001] The invention relates to the technical field of engine cable tail accessories, and discloses a tail accessory electromagnetic shielding structure and a manufacturing method thereof. Background Art

[0002] In the field of cable processing and manufacturing, wire clamping tail accessories are usually used to fix the wires behind the connector and connect the cable shielding layer to the connector and the tail accessory shell. With the increase in the demand for cable environmental resistance, traditional wire clamping tail accessories can no longer meet the use requirements of cables in environments with strong electromagnetic interference. In order to make the cable more adaptable to high electromagnetic interference environments, during the use of the existing barrel-type tail accessories, the cable's anti-electromagnetic interference ability is enhanced by putting the sheath on the tail barrel of the tail accessory and tying it or bundling and welding the wire core. Although this process treatment method can enhance the cable's anti-electromagnetic interference ability to a certain extent, the improvement effect is not obvious, and this process treatment method requires the use of auxiliary materials to fix the binding material, the process is relatively cumbersome, and the final appearance of the cable after treatment is poor. Summary of the invention

[0003] The object of the present invention is to provide a tail accessory electromagnetic shielding structure and a manufacturing method thereof, which can make the tail accessory electromagnetic shielding structure more beautiful in appearance, ensure a higher degree of fixation between the cable shielding layer and the tail accessory shell, and significantly enhance the overall anti-electromagnetic interference capability of the cable.

[0004] In order to achieve the above technical effects, the technical solution adopted by the present invention is:

[0005] A tail attachment electromagnetic shielding structure, comprising:

[0006] A shielding sheath, the shielding sheath extends from the outer wall of the cable body and is sleeved on the tail barrel of the tail accessory of the cable connector; the shielding sheath is provided with a folded layer at a position where it contacts the tail accessory, and the folded layer is folded back toward the inside of the shielding sheath;

[0007] A steel tie is sleeved outside the shielding sheath on the tail cylinder of the tail accessory to fix the shielding sheath on the tail cylinder of the tail accessory.

[0008] Furthermore, an anti-skid groove is provided on the outer wall of the tail cylinder, and the number of the steel tie straps sleeved on the tail cylinder is at least two, and one of the steel tie straps is sleeved on the outer wall of the tail cylinder corresponding to the anti-skid groove.

[0009] Furthermore, the anti-slip groove is located between the folding starting end of the folding layer and the end of the folding layer.

[0010] Furthermore, an insulating coating material layer is provided between the conductive wires of the cable body located in the internal channel of the tail attachment and the inner wall of the tail attachment.

[0011] In order to achieve the above technical effects, the present invention also provides a method for manufacturing a tail attachment electromagnetic shielding structure, comprising:

[0012] Weaving the shielding sheath on the cable body to the tail barrel of the tail accessory;

[0013] Folding and weaving the shielding sheath back into the shielding sheath to form a folded layer sleeved on the tail cylinder;

[0014] The outer wall of the tail cylinder is fixed by using a shielding sheath with a folded layer on the inner side of a steel tie.

[0015] Furthermore, an annular anti-skid groove is provided on the outer wall of the tail cylinder. During the weaving process of the shielding sheath toward the tail cylinder of the tail attachment, the outer shielding sheath is folded back into the shielding sheath for weaving after its weaving length exceeds the anti-skid groove to form a folded layer sleeved on the tail cylinder.

[0016] Furthermore, the weaving length of the folded layer woven inwardly is longer than the anti-slip groove.

[0017] Furthermore, there are at least two steel cable ties, one of which is sleeved on the outer shielding sheath corresponding to the anti-slip groove.

[0018] Furthermore, it also includes wrapping an insulating coating material layer around the outer wall of the conductor of the cable body located in the internal channel of the tail attachment.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] 1. The present invention replaces the outward reverse braiding by folding the braided cable shielding sheath inward, making the cable more beautiful in appearance and smoother in transition;

[0021] 2. By using steel tie, the shielding sheath formed by folding and weaving to form a double-layer structure is tightly fixed on the outer wall of the tail barrel of the tail accessory, so as to realize the mechanical fixation between the shielding sheath and the tail accessory. While improving the overall shielding effectiveness of the overlap between the cable shielding sheath and the tail accessory and improving the overall anti-interference ability of the cable, the contact between the cable shielding layer and the shell of the tail accessory is further made more reliable, the contact resistance is smaller, and the signal transmission is more stable.

[0024] The present invention is further described in detail below in conjunction with the embodiments and drawings. However, it should not be understood that the scope of the above subject matter of the present invention is limited to the following embodiments, and all technologies realized based on the content of the present invention belong to the scope of the present invention.

[0025] Example

[0026] See also Figure 1 , a tail attachment electromagnetic shielding structure, comprising:

[0027] A shielding jacket 1, the shielding jacket 1 extends from the outer wall of the cable body and is sleeved on the tail barrel 201 of the tail accessory 2 of the cable connector; the shielding jacket 1 is provided with a folding layer 101 at a position in contact with the tail accessory 2, and the folding layer 101 is folded back toward the inside of the shielding jacket 1;

[0028] The steel tie 3 is sleeved on the shielding sheath 1 on the tail cylinder 201 of the tail accessory 2 to fix the shielding sheath 1 on the tail cylinder 201 of the tail accessory 2 .

[0029] In this embodiment, the braided cable shielding sheath 1 replaces the outward reverse braiding by folding inwards, so that the cable appearance is more beautiful and the transition is smoother. The shielding sheath 1 formed by folding back and weaving to form a double-layer structure is tightly fixed to the outer wall of the tail cylinder 201 of the tail accessory 2 by using steel tie bands 3, so as to achieve mechanical fixation between the shielding sheath 1 and the tail accessory 2. While improving the overall shielding effectiveness of the overlap between the cable shielding sheath 1 and the tail accessory 2 and the overall anti-interference ability of the cable, the contact between the cable shielding layer and the shell of the tail accessory 2 is further made more reliable, the contact resistance is smaller, and the signal transmission is more stable.

[0030] The manufacturing method of the electromagnetic shielding structure of the tail attachment 2 in this embodiment includes:

[0031] Step 1: Weave the shielding sheath 1 sleeved on the cable body onto the tail barrel 201 of the tail accessory 2;

[0032] Step 2: folding and weaving the shielding sheath 1 back into the shielding sheath 1 to form a folded layer 101 sleeved on the tail cylinder 201;

[0033] Step 3: Use the shielding jacket 1 with the folded layer 101 on the inner side of the steel tie 3 to fix the outer wall of the tail cylinder 201.

[0034] In this embodiment, the number of the steel tie bands 3 sleeved on the tail cylinder 201 is at least two, which makes the fixing more firm and improves the shielding efficiency of the cable.

[0035] In this embodiment, an annular anti-skid groove 4 is provided on the outer wall of the tail cylinder 201. During the weaving process of the shielding sheath 1 toward the tail cylinder 201 of the tail accessory 2, the outer shielding sheath 1 is folded back inwardly and woven to form a folded layer 101 sleeved on the tail cylinder 201 after its weaving length exceeds the anti-skid groove 4, so that the anti-skid groove 4 is located between the folded starting end of the folding layer 101 and the end of the folding layer 101; then one of the steel tie ties 3 is sleeved on the outer shielding sheath 1 corresponding to the anti-skid groove 4, so that the cable shielding layer and the shell of the tail accessory 2 are more fixed, so that the overall anti-electromagnetic interference ability of the cable is significantly enhanced.

[0036] An insulating coating material layer is provided between the conductor of the cable body located in the internal channel of the tail attachment 2 and the inner wall of the tail attachment 2. For example, in this embodiment, the conductor inside the cylindrical tail attachment 2 is wrapped with a highly wear-resistant insulating material to form an insulating coating material layer, which plays a role in fixing the cable conductor, avoiding the problem of friction between the conductor inside the tail attachment 2 and the inner wall of the tail attachment 2, thereby damaging the conductor, making the cable more reliable and the signal transmission more stable.

[0037] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
