Description

Technical Field

[0001] This utility model relates to a jumper, and more particularly to an SPE jumper. Background Technology

[0002] A single-pair Ethernet (SPE) patch cord is a specialized cable used to implement single-pair twisted-pair Ethernet communication. Its core design goal is to reduce space footprint and cost while meeting the Ethernet connectivity needs of Industrial Internet of Things (IIoT) field devices.

[0003] In order to ensure the reliability and correct polarity of the connection, and to meet the needs of compact and high-density cabling in industrial environments, existing SPE patch cords often adopt a male and female connector design. However, existing male and female connector SPE patch cords have problems such as simple connection structure, poor vibration and pulling resistance, and poor waterproof performance at the male and female connector joint. Summary of the Invention

[0004] To address the problems of existing technologies, this utility model provides an SPE patch cord that not only enables quick connection of SPE patch cords but also meets IP67 / IP68 dustproof and waterproof requirements, effectively preventing connection loosening or failure caused by vibration, pulling, or harsh environments, ensuring transmission stability, and is suitable for extreme industrial environments.

[0005] The technical solution adopted in this utility model is as follows:

[0006] An SPE patch cord includes a male cable connector assembly and a female cable connector assembly. The male cable connector assembly includes a male cable and an SPE plug at the front end, with a male connector at the rear end of the male cable. The female cable connector assembly includes a female cable, with a female connector at the front end of the female cable that plugs into the male connector. After the male and female connectors are plugged in, a plastic spiral assembly is externally fitted onto them.

[0007] Preferably, the plastic spiral assembly includes a plastic body sleeved on the outside of the male connector and a plastic mesh tail sleeved on the outside of the female connector. The front end of the plastic body has a tightening part inside, and the front end of the plastic body has an external plastic thread for screwing a nut. The rear end of the plastic body has an internal plastic thread on its inner wall. The front end of the plastic mesh tail has an external plastic thread, and the external plastic thread is screwed into the internal plastic thread.

[0008] Preferably, the male connector includes a male metal shell, a male plastic body is disposed inside the male metal shell, a male terminal is disposed inside the male plastic body, and the male terminal is electrically connected to the male cable at the front.

[0009] Preferably, the female connector includes a female metal shell, a female plastic body is disposed inside the female metal shell, a female terminal is disposed inside the female plastic body, and the female terminal is electrically connected to the female cable behind it via a PCB board.

[0010] Preferably, a rubber ring is provided between the nut and the plastic body.

[0011] The beneficial effects of the technical solution provided by this utility model are:

[0012] 1. The SPE connector used in this solution is significantly smaller than that of traditional RJ45 patch cords, achieving approximately twice the connection density per unit area. Simultaneously, the cable diameter of the SPE patch cord is reduced by up to 60% compared to traditional Ethernet patch cords (e.g., from 6.0mm to 2.4mm). This design allows for the deployment of more network links in limited spaces (such as patch panels, cabinets, or narrow industrial cable trays), significantly improving cabling space utilization.

[0013] 2. The jumper cables are connected by a double sealing ring and a plug-in structure to achieve comprehensive protection at the interface, meeting the IP67 / IP68 dustproof and waterproof requirements. This effectively prevents the connection from loosening or failing due to vibration, pulling or harsh environments, ensuring transmission stability and coping with extreme industrial environments.
