Description

Technical Field

[0001] The utility model relates to the technical field of shielding sleeves, in particular to a shielding zipper sleeve. Background Art

[0002] With the widespread use of electronic devices and the rapid development of communication technology, electromagnetic interference (EMI) and electromagnetic compatibility (EMC) issues are becoming increasingly prominent. In electronic devices, cable harnesses are important channels for signal transmission and power supply, and their shielding effect directly affects the performance of the entire system.

[0003] Traditional cable shielding sleeves are usually composed of a braided layer of metal wire and a plastic film to form a protective layer. The grid structure formed by the metal wire on the braided shielding sleeve effectively shields the electromagnetic radiation of the cable to ensure electromagnetic compatibility and normal operation of the equipment.

[0004] During the implementation process, the electric cables need to be passed through the cable shielding sleeve, which is inconvenient for installation and removal and requires more labor. Utility Model Content

[0005] The purpose of the utility model is to provide a shielded zipper sleeve, aiming to solve the above problems.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A shielded zipper sleeve comprises: a sleeve body, a buckle assembly, and a slider; the sleeve body is an open structure, with a first connecting strip and a second connecting strip provided on both sides of the opening; and a shielding layer is provided on the inner wall of the sleeve body to enhance electromagnetic shielding effect;

[0008] It is characterized in that the snap assembly is connected by a Y-channel mechanical sliding coupling with a pull head, and the lower end of the first connecting strip extends to form a shielding piece, which provides additional shielding effect after the snap assembly is coupled; a third connecting strip is provided on the shielding piece.

[0009] Furthermore, it is characterized in that the snap assembly includes a male snap belt and a female snap belt, the male snap belt is provided with a protrusion, the female snap belt is provided with a groove, and slides through the slider Y channel to achieve mechanical coupling.

[0010] Furthermore, it is characterized in that the male buckle belt is fixedly connected to the first connecting strip, and the female buckle belt is fixedly connected to the second connecting strip, thereby ensuring the stability and consistency of the entire structure.

[0011] Furthermore, it is characterized in that one end of the shielding layer is fixedly connected to the second connecting bar, and the other end is fixedly connected to the lower part of the third connecting bar.

[0012] Furthermore, the shielding layer can be made of a metal mesh (woven from tinned copper wire), a non-magnetic metal foil (copper foil or aluminum foil), or a two-layer structure (a first layer of metal mesh and a second layer of non-magnetic metal foil). These material choices enable the shielding layer to provide varying degrees of shielding effectiveness based on specific needs.

[0013] Furthermore, it is characterized in that the sleeve body is made of flame-retardant polymer material.

[0014] Furthermore, the feature is that the shielding sheet and the first connecting strip are V-shaped, which optimizes the shielding effect and makes the entire structure more compact.

[0015] 1. Furthermore, it is characterized in that a grounding wire is fixedly provided on the third connecting bar, and the grounding wire is in contact with the shielding layer through the third connecting bar, thereby providing a grounding path for electromagnetic shielding.

[0016] The beneficial effect is: after the shielded zipper sleeve of the utility model wraps the cable, the snap assembly is connected by mechanical sliding coupling of the Y channel with the pull head, which improves the shielding effect, has a compact structure, is easy to install and disassemble, and improves work efficiency.

[0025] Reference Figure 1 As shown, a shielded zipper sleeve according to an embodiment of the present invention comprises a sleeve body 1, a buckle assembly 2, and a slider 3. The sleeve body 1 is an open structure made of a flame-retardant polymer material, with a first connecting strip 4 and a second connecting strip 5 disposed on either side of the opening. The buckle assembly 2 is mechanically coupled through the Y-channel of the slider 3, enabling the sleeve body 1 to conveniently wrap and secure cables.

[0026] The lower end of the first connecting bar 4 extends to form a shielding piece 8. This shielding piece 8 forms a V-shaped structure with the first connecting bar 4, providing additional shielding after the buckle assembly 2 is coupled, and making the entire structure more compact. A third connecting bar 6 is provided on the shielding piece 8, and a grounding wire 11 is fixedly mounted on the third connecting bar 6. The grounding wire 11 is connected to the shielding layer 7 through the third connecting bar 6, thereby providing a grounding path for the electromagnetic shield, further enhancing the electromagnetic shielding effect.

[0027] The snap assembly 2 includes a male snap band 9 and a female snap band 10. The male snap band 9 has a protrusion 91, while the female snap band 10 has a groove 101. Mechanical coupling is achieved through the Y-channel of the sliding slider 3. The male snap band 9 is fixedly connected to the first connecting strip 4, while the female snap band 10 is fixedly connected to the second connecting strip 5, ensuring the stability and consistency of the entire structure.

[0028] A shielding layer 7 is provided on the inner wall of the sleeve body 1. One end of the shielding layer 7 is fixedly connected to the second connecting bar 5, and the other end extends to the lower portion of the third connecting bar 6 for fixed connection, ensuring the continuity and integrity of the shielding layer 7. The shielding layer 7 can be made of a metal mesh (woven from tinned copper wire), a non-magnetic metal foil (copper or aluminum foil), or a two-layer structure (a metal mesh layer and a non-magnetic metal foil layer). These material choices enable the shielding layer 7 to provide varying degrees of shielding effectiveness, depending on specific needs.

[0029] The shielded zipper sleeve of this embodiment utilizes a mechanical sliding coupling between the snap assembly 2 and the Y-channel of the slider 3, ensuring that the sleeve body 1 tightly wraps and secures the cable, enhancing shielding effectiveness. Furthermore, the compact structure makes installation and removal easy, significantly improving work efficiency. Furthermore, the diverse material options for the shielding layer 7 provide varying degrees of shielding effectiveness based on specific needs, meeting the demands of diverse applications.
