Abstract

[0001] This utility model belongs to the field of power construction technology, and specifically relates to a sealing joint for power wiring. Background Technology
[0002] A sealing joint for electrical wiring is a device used in power systems to connect cables or wires and provide a sealing function. It is mainly used to prevent external substances such as moisture, dust, and corrosive gases from entering the electrical connection points, ensuring the safety and reliability of the electrical connection. Sealing joints play a crucial role in outdoor power facilities, underwater cable connections, and some industrial sites with high environmental requirements. However, in some common sealing joints, the outer insulation layer of the wire must first be peeled off, then the end of the wire is wrapped, and finally the sealing joint is installed on the outside of the wire end. This wrapping process can damage the end of the wire and may reduce the quality of wire transmission. Utility Model Content

[0018] Please see Figures 1-3This utility model provides the following technical solution: a sealing connector for power wiring, including a metal conductive plate 1, with arc-shaped limiting conductive plates 2 symmetrically fixedly connected to both sides of the metal conductive plate 1, an arc-shaped sealing connecting plate 3 provided on the outer side of the two symmetrically arranged arc-shaped limiting conductive plates 2, and one side of the arc-shaped sealing connecting plate 3 fixedly connected to one side of the metal conductive plate 1, a metal conductive rod 31 fixedly connected to the inner side of the arc-shaped sealing connecting plate 3, and the metal conductive rod 31 located between the two symmetrically arranged arc-shaped limiting conductive plates 2, an insulating rubber protective sleeve 4 fixedly connected to the outer side of the arc-shaped limiting conductive plate 2 and the arc-shaped sealing connecting plate 3, and an outer insulating protective shell 41 sleeved on the outer side of the insulating rubber protective sleeve 4, and an installation connection groove 42 formed between the insulating rubber protective sleeve 4 and the outer insulating protective shell 41, and a plurality of fastening pull ropes 5 installed inside the installation connection groove 42, and both ends of the plurality of fastening pull ropes 5 extending to the outside of the outer insulating protective shell 41.
[0019] In this implementation scheme: the metal conductive plate 1 is a workpiece that conducts electricity between two wires when wiring, providing a carrier for communication between the ends of the two wires. The arc-shaped limiting conductive plates 2 located on both sides of the metal conductive plate 1 are used to limit the wires. When connecting the wires, the insulation layer at the end of the wire is first peeled off, and then the arc-shaped limiting conductive plate 2 is placed on the outside of the wire end after the insulation layer has been peeled off. The arc-shaped sealing connecting plate 3 between the two arc-shaped limiting conductive plates 2 is used to fill the gap between the two arc-shaped limiting conductive plates 2. The metal conductive rod 31 located inside the arc-shaped sealing connecting plate 3 plays a conductive role. At this time, the arc-shaped sealing connecting plate 3, with the cooperation of the metal conductive rod 31 and the arc-shaped limiting conductive plates 2, forms a limiting component that limits the outer end of the wire. When connecting the end of the wire to the limiting component, one of the arc-shaped limiting conductive plates 2 can be folded outward by a small range to enlarge the diameter of the wire end. Then the end of the wire... The insulating rubber protective sleeve 4, located outside the arc-shaped limiting conductive plate 2 and the arc-shaped sealing connecting plate 3, serves as a connection and forms a protective component on the outside of the arc-shaped limiting conductive plate 2 and the arc-shaped sealing connecting plate 3. The outer insulating protective shell 41, located outside the insulating rubber protective sleeve 4, forms the outer protective component of the entire sealing joint, used to protect the internal components. The mounting groove 42 provides space for the installation of the fastening pull rope 5. After the entire sealing joint and the end of the wire are installed, the wire and the sealing joint can be fixed by tightening the fastening pull rope 5. At this time, with the cooperation of the metal conductive plate 1, the arc-shaped limiting conductive plate 2, and the arc-shaped sealing connecting plate 3, the entire sealing joint can provide a relatively stable power transmission between the ends of the two wires after the connection is completed. At the same time, the installation of the entire sealing joint and the wire by tightening the pull rope 5 facilitates the operation of the staff and helps to improve the work efficiency of the staff.
[0020] Both ends of the arc-shaped sealing connecting plate 3 are fixedly connected with inclined connecting plates 32; the inclined connecting plates 32 serve as a transition.
[0021] A conductive film 21 is fixedly connected to the inner side of the arc-shaped limiting conductive plate 2; the conductive film 21 plays a role in enhancing conductivity.
[0022] Several fastening pull ropes 5 are fixedly connected to one end of a limiting connector 51; wherein the limiting connector 51 is used to close the two ends of the fastening pull ropes 5.
[0023] The limiting connector 51 has several limiting slots 511 inside, and the other end of the limiting connector 51 extends through the limiting slots 511 to the outside of the limiting connector 51; wherein the limiting slots 511 are used to provide a through channel for the end of the fastening pull rope 5.
[0024] The outer insulating protective shell 41 is provided with a first through groove 411; wherein the first through groove 411 is used to provide an external through channel for the limiting connecting seat 51 and the end of the fastening pull rope 5.
[0025] Both ends of the outer insulating protective shell 41 are fixedly connected with rubber anti-slip sleeves 44; the rubber anti-slip sleeves 44 are used to improve the connection stability between the entire sealed joint and the wire.
[0026] A connecting support plate 43 is fixedly connected between the outer insulating protective shell 41 and the insulating rubber protective sleeve 4; the connecting support plate 43 plays a supporting role.
[0027] The working principle and usage process of this utility model are as follows: When it is necessary to connect the ends of two wires, the insulation layer at the end of the wire is first peeled off. Then, the arc-shaped limiting conductive plate 2 is placed on the outside of the wire end after the insulation layer has been peeled off. When connecting the wire end and the limiting component, one of the arc-shaped limiting conductive plates 2 can be folded outward slightly to enlarge the diameter of the wire end. Then, the wire end is placed inside the arc-shaped limiting conductive plate 2. After the entire sealing joint and the wire end are installed, the wire and the sealing joint can be fixed by tightening the fastening pull rope 5.
