Description

Technical Field

[0001] The utility model relates to the technical field of connectors, in particular to a high-speed anti-interference wiring harness. Background Art

[0002] With the continuous advancement of technology, the demand for network applications continues to increase, especially in some important fields that require higher and faster transmission requirements. For some professional application fields such as medical care, scientific research and high-performance computing, higher speed and reliability network connections are required.

[0003] When processing the D-SUB connector assembly on the right end, due to the small width and thickness of the terminal, the large number of holes, the high insertion force, the unstable connection with the plastic shell, and the tendency to shake, it cannot be properly fixed, affecting the reliability of signal transmission. In severe cases, it may cause the terminal to fall off, resulting in quality problems. When using Category 7 cables, since there are many shielding wires in the cable, if they are not fixed, it is easy to cause them to become scattered and affect product performance.

[0004] A wiring harness with high transmission rate and high anti-interference performance is proposed. It has high transmission rate and fully shielded design to minimize interference and ensure a more stable connection. Utility Model Content

[0005] The main technical problem solved by the utility model is to provide a high-speed anti-interference wiring harness with a firm structure, safety and reliability, high transmission rate, and a fully shielded design to minimize interference and ensure a more stable connection.

[0006] In order to solve the above technical problems, a technical solution adopted by the utility model is: to provide a high-speed anti-interference wiring harness, which includes a cable, a crystal head, and a connector. The left and right ends of the cable are respectively connected to a crystal head and a connector, and the connection between the cable and the crystal head is covered with a crystal head sheath. The connector includes a connector body, a metal shielding shell, a screw and a mesh tail sheath. The connector body includes a plastic shell and two rows of riveted terminals plugged into the plastic shell. The riveted terminals are connected to the cable, and UV glue is applied at the connection between the cable and the plastic shell. The connector body is inserted into the metal shielding shell. Two screws that can lock the connector body are installed on the metal shielding shell, and a mesh tail sheath is installed at the connection between the metal shielding shell and the cable.

[0007] Preferably, the cable end is peeled to retain the braided layer and the connecting wires, the wires are wrapped in the braided layer, the braided layer is folded back and covered on the cable outer sheath, copper foil is wrapped around the folded braided layer, and the braided layer and copper foil are covered with a heat shrink tube.

[0008] Preferably, the screw is threadedly connected to the metal shielding shell, and connecting ends are extended outward at both ends of the plastic shell, and threaded holes that cooperate with the screw are provided at the connecting ends.

[0009] Preferably, the metal shielding shell adopts an upper and lower split shell, which is assembled by crimping. The head of the metal shielding shell is provided with a slot for installing the connector body, and the tail of the metal shielding shell is provided with a circle of raised blocks that are clamped on the mesh tail sleeve, and the mesh tail sleeve is provided with a slot that cooperates with it.

[0010] Compared with the prior art, the beneficial effects of the present invention are:

[0011] Use UV glue to seal the connector. UV glue has the advantages of energy saving, environmental protection, economy and high efficiency. It can not only achieve the purpose of fixing the cable, but also meet environmental protection requirements and prevent the hidden danger of unstable wire connection caused by repeated use of the wire harness.

[0012] Use copper foil to fix the internal braiding of the cable. Copper foil has good conductivity and excellent continuity, and provides electromagnetic shielding effect. On the one hand, it prevents the braiding from short-circuiting on the core wire, and on the other hand, it can also achieve the effect of grounding, which is safer and more reliable.
