Description

Technical Field

[0001] The invention relates to a cable connector, in particular to a welding-free coaxial cable connector, belonging to the technical field of electronic communications. Background Art

[0002] Coaxial cable is a kind of wire and signal transmission line, which is generally made of four layers of materials: the innermost is a conductive copper wire, surrounded by a layer of plastic (used as an insulator and dielectric) outside the wire, and a thin mesh conductor (usually copper or alloy) outside the insulator, and then the outermost insulating material outside the conductor as the outer sheath. This structure of coaxial cable gives it high bandwidth and excellent noise suppression characteristics. The bandwidth of coaxial cable depends on the length of the cable. A 1km cable can achieve a data transmission rate of 1Gb / s~2Gb / s. Longer cables can also be used, but the transmission rate must be reduced or an intermediate amplifier must be used. At present, coaxial cables have been largely replaced by optical fibers, but are still widely used in cable television and some local area networks.

[0003] In communications, coaxial cables are often used to transmit 2Mbit / s-level services. This type of cable is also often called a 2M cable. It is widely used in various power grid production and operation environments, such as the interconnection between transmission equipment and routers, and the interconnection between transmission equipment and relay protection interface devices. When using coaxial cables to interconnect devices with communication needs, it is first necessary to make a terminated coaxial cable. The key core step is to spot weld and crimp the L9 or BCN coaxial cable connector (also called 2M head) on the coaxial cable to terminate the cable, and then use it to transmit and receive two devices that communicate with each other, forming a point-to-point physical communication path to achieve information exchange.

[0004] In practical applications, it is often necessary to butt-join coaxial cables. Common methods for butt-joining coaxial cables include crimping, threading, welding, screw-on, etc. Crimping is one of the most common methods for butt-joining coaxial cables. It uses crimping pliers to connect the connector and the cable together. First, the cable end needs to be stripped to remove the outer sheath and insulation layer to expose a certain length of the center conductor. Then, insert the connector into the end of the cable to ensure that the center conductor is connected to the center hole of the connector. Finally, use the crimping pliers to apply sufficient pressure to tighten the connector to the cable. The threading method is also a common method for butt-joining coaxial cables. It is usually used to connect TV antennas or other devices. In this method, the inner hole of the connector is a threaded structure, and the end of the cable needs to be stripped of a certain length of the outer sheath and insulation layer to expose a part of the center conductor. Then, insert the connector into the end of the cable and tighten the connector until the connector is tightly connected to the cable. The welding method is mainly used to make permanent connections to coaxial cables. In this method, the end of the cable needs to be stripped to expose a certain length of the center conductor. Then, apply solder paste on the center conductor and insert the connector into the center conductor. Next, use an electric welder to weld the connector and the center conductor of the cable to firmly connect them together. The screw method is a tool-free docking method suitable for some simple connections. In this method, the outer hole of the connector is a threaded structure, and the end of the cable is also stripped of a certain length of outer sheath and insulation. Then, insert the end of the cable into the outer hole of the connector and rotate the connector at the same time until a tight connection is formed between the cable and the connector.

[0005] At present, there are the following problems in making 2M cables with L9 or BNC coaxial cable heads: (1) To terminate the 2M cable, a soldering iron is needed to solder the core wire of the coaxial cable that transmits the signal to the terminal of the center pin of the connector. The shielding copper wire wrapped around the coaxial cable is pressed onto the connector shell using crimping pliers. During the core wire welding step, due to the small welding surface and the easy melting and shrinkage of the insulation layer of the cable core wire and shielding wire due to heat, high requirements are placed on the welding operation accuracy and welding time of the operator. The operation is difficult and prone to cold soldering, desoldering, and welding short circuits. The core wire and shielding wire insulation may even be short-circuited due to heat loss due to long welding time, resulting in service interruption or bit errors. In some cases of cold soldering, even after a period of normal service operation, poor contact may occur due to decreased mechanical strength, causing intermittent service. This type of failure often The troubleshooting is time-consuming and often causes long-term damage to the business; (2) The welding of the coaxial cable head requires two people, one person uses a clamping tool to fix the cable head in a suitable position, and the other person uses an electric soldering iron to weld. Not only will the welding quality be affected by the two people, but the two people make a joint together, and the work efficiency is low. Often in the engineering stage, a set of convergence layer transmission equipment has 64 2M output lines, and 2*64 coaxial cable heads need to be made. It is a big challenge to the welding quality and physical fitness of the operators. Often in the later stage of production, the welding quality is unstable due to the long-term repetitive work of the staff and the long-term heating of the welding tools, resulting in welding defects, rework, and reduced work efficiency; (3) The 2M head currently used can only be welded once. If a welding defect occurs, it is difficult to weld again and can only be discarded, resulting in a certain amount of waste. Therefore, it is necessary to improve the existing technology. Summary of the invention
