Description

Technical Field

[0001] This utility model relates to the field of signal line shielding technology, specifically to a signal line shielding layer that facilitates winding and connection. Background Technology

[0002] During the manufacturing process, a shielding layer needs to be wrapped around the outer surface of the signal cable to shield and protect the signal during transmission, thus preventing interference.

[0003] When existing signal line shielding layers are wound, they are only bonded and wound through the adhesive layer on the shielding layer. The connection stability of the overlapping and winding positions of the shielding layer cannot be guaranteed, which affects the winding connection strength of the shielding layer. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the existing defects and provide a signal line shielding layer that is easy to wind and connect. By setting the limiting ribs and the locking ribs, when the shielding layer is wound onto the signal line, the locking ribs of the upper shielding layer will be locked between the two limiting ribs in the stacked winding area. This makes the upper and lower shielding layers firmly connected during the winding process, avoids the shielding layers from misalignment and slippage, and ensures the winding connection strength of the shielding layer. This can effectively solve the problems in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a signal line shielding layer that facilitates winding and connection, comprising a shielding layer, wherein a locking rib is provided on one side of the shielding layer, and limiting ribs are provided on both sides of the locking rib, and the shielding layer comprises: a conductive adhesive layer, a metal foil layer, and a tin-plated layer.

[0006] Furthermore, the shielding layer is wound with signal wires, and both the locking ribs and the limiting ribs are rolled into shape.

[0007] Furthermore, the conductive adhesive layer is bonded to the metal foil layer, and the tin plating layer is electroplated on the surface of the metal foil layer.

[0008] Furthermore, when the shielding layer is wound around the signal line, the locking rib and the limiting rib are locked together.

[0009] Furthermore, the width of the limiting rib is 1mm, and the width of the locking rib is 3mm.

[0010] Furthermore, both the limiting rib and the locking rib have arc-shaped cross-sections.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of limiting ribs and locking ribs, ensures that when the shielding layer is wound onto the signal line, the locking ribs of the upper shielding layer will be locked between the two limiting ribs in the stacked winding area of ​​the shielding layer. This ensures that the upper and lower shielding layers are firmly connected during the winding process, preventing the shielding layers from misaligning and sliding, and guaranteeing the winding connection strength of the shielding layer.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-3 This embodiment provides a technical solution: a signal line shielding layer that is easy to wind and connect, including a shielding layer 1, a locking rib 3 on one side of the shielding layer 1, and limiting ribs 2 on both sides of the locking rib 3. The shielding layer 1 includes: a conductive adhesive layer 101, a metal foil layer 102 and a tin-plated layer 103.

[0019] like Figure 1-3 As shown, when the shielding layer 1 is wound onto the signal line 4, the locking ribs 3 of the upper shielding layer 1 will engage with the limiting ribs 2 of the lower shielding layer 1, thereby making the adjacent wound shielding layers 1 stably connected. At the same time, the conductive adhesive layer 101 on the shielding layer 1 can bond the upper and lower shielding layers 1 together, thereby increasing the overall winding strength of the shielding layer 1.

[0020] The shielding layer 1 is wrapped with signal wire 4, and the locking rib 3 and the limiting rib 2 are both rolled and formed.

[0021] The conductive adhesive layer 101 is bonded to the metal foil layer 102, and the tin plating layer 103 is electroplated on the surface of the metal foil layer 102. The metal foil layer 102 can be copper foil or aluminum foil. A PET, PP or PI film layer is disposed between the conductive adhesive layer 101 and the metal foil layer 102.

[0022] When the shielding layer 1 is wound and connected to the signal line 4, the locking rib 3 and the limiting rib 2 are locked together.

[0023] The width of the limiting rib 2 is 1mm, and the width of the locking rib 3 is 3mm.

[0024] Both the limiting rib 2 and the locking rib 3 have circular arc cross-sections.

[0025] The working principle of the signal line shielding layer that facilitates winding and connection provided by this utility model is as follows: Figures 1-3 As shown, when the shielding layer 1 is wound onto the signal line 4, the locking ribs 3 of the upper shielding layer 1 will engage with the limiting ribs 2 of the lower shielding layer 1, thereby making the adjacent wound shielding layers 1 stably connected. At the same time, the conductive adhesive layer 101 on the shielding layer 1 can bond the upper and lower shielding layers 1 together, thereby increasing the overall winding strength of the shielding layer 1.

[0026] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
