Description

Technical Field

[0001] The utility model relates to an insulating terminal cap, in particular to an insulating terminal cap for an outdoor circuit, and belongs to the technical field related to electric power. Background Art

[0002] Insulated terminals are mainly used for connecting wires and cables, and provide electrical isolation during connection to prevent short circuits between connection points or other electrical problems. Insulated terminals used outdoors are exposed to harsher environmental conditions, so they need to have higher waterproof, dustproof, and weather-resistant properties.

[0003] However, when the insulating electronic cap used in the outdoor circuit is connected to the wire, because the insulating electronic cap is composed of multiple shells, it is necessary to disassemble the insulating electronic cap, and then fix the end of the wire where the metal is exposed (i.e., the conductive connection part of the wire) in one of the shells by bolts or other means, and then reinstall the disassembled shell. Under the protection of multiple shells, the conductor part of the fixedly connected wire will be strictly protected and can adapt to the outdoor environment well. However, this kind of insulating electronic cap is relatively cumbersome in installation and removal. When there are many lines, it will greatly affect the construction efficiency of workers.

[0004] Therefore, it is urgent to improve the insulating terminal cap for outdoor circuits to solve the above-mentioned problems. Utility Model Content

DETAILED DESCRIPTION

[0024] The following will describe the implementation methods of the present application in detail with the help of accompanying drawings and examples, so that the implementation process of how the present application uses technical means to solve technical problems and achieve technical effects can be fully understood and implemented accordingly.

[0025] like Figure 1-Figure 7 As shown, the insulating terminal cap for outdoor circuit provided in this embodiment includes an outer shell 1 and a fastening mechanism. The fastening mechanism is located inside the outer shell 1 and is used to clamp and fix the conductive connection part of the wire. When in use, the end of the wire exposed by the conductor metal is first inserted into the outer shell 1, and then fixed by the fastening mechanism to achieve a fixed connection of the wire. Compared with the tightening and fixing method using bolts, this structure is simpler to achieve the fixing method of the wire.

[0026] A threaded rotating member 2 is arranged inside the outer shell 1, and a threaded ring 3 is threadedly connected to the threaded rotating member 2. The threaded ring 3 is driven to move along the axial direction of the threaded rotating member 2 by rotating the threaded rotating member 2. A guide rod 18 is fixedly connected to the inside of the outer shell 1, and the guide rod 18 is slidably connected to the threaded ring 3. A pushing pressure rod 4 is provided on the threaded ring 3, and the end of the pushing pressure rod 4 away from the threaded ring 3 is connected to the fastening mechanism. A supporting rotating member 7 is fixedly connected to the inside of the outer shell 1, and the threaded rotating member 2 is rotatably connected to the supporting rotating member 7. A hand-turning part 8 is fixedly connected to the threaded rotating member 2, and the hand-turning part 8 is located outside the outer shell 1. When one end of the metal conductor exposed on the wire (not shown in the figure) is inserted into the appropriate position inside the outer shell 1, the hand-turning part 8 is then held and rotated, which will drive the threaded rotating member 2 to rotate on the supporting rotating member 7. When the threaded rotating member 2 rotates, it will drive the threaded ring 3 to move along the axial direction of the supporting rotating member 7, and then drive the pushing pressure rod 4 to move along the axial direction of the supporting rotating member 7.

[0027] like Figure 4As shown, the fastening mechanism includes two clamping plates 60 which are opposite to each other and have conductive properties, and fixed blocks 61 located on both sides of the clamping plates 60. The fixed blocks 61 are fixedly connected to the inner wall of the outer shell 1. A sliding groove 62 is provided on the clamping plate 60. One end of the pushing pressure rod 4 is slidably connected to the sliding groove 62. Sliding plates 63 are fixedly connected to both sides of the clamping plate 60, and the sliding plates 63 are slidably connected to the fixed blocks 61. Under the action of the sliding plates 63, the clamping plates 60 can only perform a linear motion perpendicular to the axis of the supporting rotating member 7. The opposite side of the two clamping plates 60, that is, the side where the clamping plates 60 and the pushing pressure rod 4 are slidably connected is an inclined surface, and the inclination direction of the inclined surface is from the end away from the supporting rotating member 7 to the end close to the supporting rotating member 7. Therefore, when the pushing pressure rod 4 moves, one end of it will continuously squeeze the surface of the clamping plate 60, and finally the two clamping plates 60 gradually move closer to each other. When the two clamping plates 60 move closer, the wires located between the two clamping plates 60 will be fastened.

[0028] The connector 5 has one end in contact with the fastening mechanism, and the other end of the connector 5 penetrates the outer shell 1 and extends to the outside. The connector 5 is composed of an insulating tube 501, a No. 1 contact tube 502, and a No. 2 contact tube 503. The insulating tube 501 is fixedly connected to the outer shell 1, and the No. 1 contact tube 502 and the No. 2 contact tube 503 are respectively slidably connected at the two ends of the insulating tube 501. A spring 504 is connected between the No. 1 contact tube 502 and the No. 2 contact tube 503. The No. 1 contact tube 502 contacts one end of the pressing plate 60, and the metal conductor exposed on the wire is tightened by the fastening mechanism. When one end is fastened, the clamping plate 60 on the fastening mechanism is in contact with the conductor of the wire, and the clamping plate 60 is made of conductive material, and the No. 1 contact tube 502 on the connector 5 is always in contact with the clamping plate 60. Therefore, after the wire starts to conduct electricity, the current on the wire can be transmitted to the spring 504 through the clamping plate 60 and the No. 1 contact tube 502, and then to the No. 2 contact tube 503. The No. 2 contact tube is a connecting structure used to connect with other wires. During this process, the insulating tube 501 is in a non-conductive state, which also ensures the overall insulation of the structure.

[0029] A connector 15 is fixedly connected to one end of the outer shell 1 close to the insulating tube 501. The diameter of the connector 15 is larger than the diameter of the insulating tube 501. The outer wall and the outer wall of the connector 15 are provided with a threaded portion 16. The threaded portion 16 of the outer wall of the connector 15 is threadedly connected with a protective cap 17. When it is not used for conductive connection, installing the protective cap 17 on the connector 15 helps to protect the conductive parts of the structure. When it is used for conductive connection, the protective cap 17 is removed, and then the wire can be conductively connected. It is only necessary to install the same device structure on another wire, and then install connectors 15 of different straight-in sizes, so that the connectors 15 on the two wires can be threadedly connected to each other, and then the two wires are conductively connected, thereby completing the protection of the wires for outdoor use and ensuring the sealing of the two wires when connected.

[0030] An inlet 9 is provided at one end of the housing away from the connector 5, and a fixing tube 10 with a thread is fixedly connected to the inlet 9. A tightening portion 11 is provided at one end of the fixing tube 10 away from the housing 1, and an extrusion tube 12 is threadedly connected to one end of the fixing tube 10 away from the housing 1, and the inner wall of the extrusion tube 12 is chamfered at the center and contacts the tightening portion 11, and a sealing ring 13 is movably connected to the inner wall of the end of the extrusion tube 12 away from the housing 1. According to the diameter of the wire, a suitable sealing ring 13 is selected and installed to ensure that the sealing ring 13 is in contact with the wire. The outer surfaces of the wires can be in better contact with each other. After the fastening mechanism fixes one end of the wire, the extrusion tube 12 is rotated to move on the fixing tube 10. During the movement of the extrusion tube 12, the inclined chamfered inner wall will continuously squeeze the tightening part 11, and the tightening part 11 will continuously clamp the outer surface of the wire. After the extrusion tube 12 is twisted to a certain extent, the tightening part 11 will fix the wire so that it will not easily detach from the device structure, further ensuring the stable state of the wire fixed between the two clamping plates 60.

[0031] like Figure 1-Figure 7As shown, the principle of the insulating terminal cap for outdoor circuits provided in this embodiment is as follows: when in use, one end of the conductor of the wire leaking out is inserted from the wire inlet 9 until it moves to the position between the two clamping plates 60 and stops, and then the fastening mechanism is used to clamp the wire between the two clamping plates 60. When the fastening mechanism is in use, the hand-turning part 8 is first held and rotated, which will drive the threaded rotating member 2 to rotate on the supporting rotating member 7. When the threaded rotating member 2 rotates, the threaded ring 3 threadedly connected to it will move forward under the action of the guide rod 18, thereby driving the pushing pressure rod 4 to move toward the direction of the clamping plate 60. Because the two clamping plates 60 and the pushing pressure rod 4 are slidably connected on one side, the pushing pressure rod 4 will continuously squeeze the surface of the clamping plate 60 when it moves, and finally the two clamping plates 60 gradually move closer to each other. When the two clamping plates 60 move closer, the wires between the two clamping plates 60 will be fastened. After one end of the wire is tightened to a certain degree, the rotation of the threaded rotating part 2 is stopped, and then the extrusion tube 12 is rotated to move on the fixed tube 10. During the movement of the extrusion tube 12, the inner wall of the inclined chamfered shape will continuously squeeze the tightening part 11, and the tightening part 11 continuously clamps the outer surface of the wire. After the extrusion tube 12 is twisted to a certain degree, the tightening part 11 fixes the wire so that it will not easily detach from the device structure, further ensuring the stable state of the fixed wire between the two clamping plates 60. At the other end of the outer shell 1, when the protective cap 17 is opened, the wire can be conductively connected. It only needs to install the same device structure on another wire, and then install connectors 15 with different straight-in sizes, so that the connectors 15 on the two wires can be threadedly connected to each other, and then the two wires are conductively connected, thereby completing the protection of the wire for outdoor use and ensuring the sealing of the two wires when connected.

Those skilled in the art should understand that hardware manufacturers may use different terms to refer to the same component. This specification and claims do not use differences in names as a way to distinguish components, but use differences in the functions of components as the criteria for distinction. For example, "including" mentioned throughout the specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve technical problems within a certain error range and basically achieve technical effects.

[0033] It should be noted that the terms "include", "comprises" or any other variations thereof are intended to cover non-exclusive inclusion, so that a product or system including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such product or system.
