Description

Technical Field

[0001] This utility model relates to the technical field of new energy vehicles, and in particular to a shielded crimping structure for dual-core wires. Background Technology

[0002] In the field of new energy vehicles, reliable connection of high-voltage wiring harnesses is crucial to the safety and electromagnetic compatibility of the entire vehicle. Traditional dual-core wires are prone to wire harness pull-out and loosening due to wire harness stress release problems, and generate additional stress on the terminals and busbar. Therefore, an integrated structure that can meet both shielding performance and prevent core wire loosening is needed to solve this problem. Utility Model Content

[0003] To address the shortcomings and defects of existing technologies, a shielded crimping structure for dual-core wires is provided. To achieve both shielding performance and prevention of core wire loosening, this utility model provides the following technical solution.

[0004] A shielded crimping structure for a dual-core cable includes a multi-core cable, an outer shielding sleeve, an inner shielding sleeve, a locking clamp, and a mounting sleeve. The outer shielding sleeve includes an outer sleeve and a plug-in portion. The multi-core cable is plugged into and fitted within the plug-in portion. The inner shielding sleeve is disposed between the outer shielding sleeve and the multi-core cable. The locking clamp fixes the plug-in portion onto the mounting sleeve.

[0005] Compared with the prior art, the multi-core cable plug-in assembly of this utility model is set inside the plug-in part of the outer shielding sleeve. The locking clamp fixes the plug-in part to the mounting sleeve, which can limit the vertical and horizontal displacement of the outer shielding sleeve, solve EMC problems, and improve the overall connection stability.

[0006] Furthermore, the outer sleeve and the insertion part are integrally stamped.

[0007] Through the above improvements, the outer sleeve and the insertion part are integrated by stamping, which can improve the overall connection strength of the outer shielding sleeve.

[0008] Furthermore, the inner shielding sleeve includes an inner sleeve and a bent portion. The inner sleeve is fitted inside the outer sleeve, and the bent portion protrudes in a direction away from the multi-core cable, with a protrusion height greater than the thickness of the outer sleeve.

[0009] With the above improvements, the inner shielding sleeve includes an inner sleeve and a bending part. The bending part protrudes away from the multi-core cable, and the protrusion height is greater than the thickness of the outer sleeve, which can hold the outer sleeve in place and prevent the outer sleeve from loosening.

[0010] Furthermore, a shielding mesh is provided on the outside of the multi-core cable. The shielding mesh includes a connecting section and a mating section. The connecting section abuts against the outer wall of the multi-core cable, and the mating section is disposed between the inner sleeve and the outer sleeve. The outer sleeve and the inner sleeve clamp the mating section.

[0011] Through the above improvements, a shielding mesh is installed on the outside of the multi-core cable. The shielding mesh includes a connecting section and a mating section. The connecting section abuts against the outer wall of the multi-core cable, so that the shielding mesh can block external interference and improve the service life of the cable. The mating section clamps the outer sleeve and the inner sleeve, so that the inner shielding sheath and the outer shielding sheath press the shielding mesh tightly, providing radial constraint and shielding performance.

[0012] Furthermore, the mounting sleeve is provided with a fixing platform, and the locking clamp includes a fastening section and abutting sections on both sides of the fastening section. The fastening section and the fixing platform lock the plug-in part tightly, and the abutting sections are fixed to the fixing platform by bolts.

[0013] With the above improvements, a fixing platform is set on the mounting sleeve, and the abutment sections on both sides of the locking clamp are abutted on the fixing platform by bolts, which can better fix the insertion part of the outer shielding mesh and prevent slippage.

[0014] Furthermore, a mating groove is provided on the fixing platform, and the mating groove abuts against the outer wall of the insertion part.

[0015] Through the above improvements, a mating groove is provided on the fixing platform. The mating groove abuts against the outer wall of the plug part, so that the plug part will not shift when tightened, thus improving stability. Attached Figure Description
