Description

Technical Field

[0001] The utility model relates to the technical field of cable intermediate joints, in particular to an easy-to-operate cable intermediate joint housing. Background Art

[0002] Cable is an electric energy or signal transmission device, usually composed of several or several groups of wires. Cable joints are also called cable heads. After the cable is laid, in order to make it a continuous line, each section of the line must be connected as a whole. These connection points are called cable joints. The cable joint in the middle of the cable line is called an intermediate joint. When the high-voltage cable is laid for a long time, it is necessary to use a cable intermediate joint for connection. The connection of the cable intermediate joint is generally carried out at the cable laying site.

[0003] For example, Chinese patent CN208874255U discloses a double-layer outer shell protective shell for a high-voltage cable intermediate joint, which includes a first protective cover, a second protective cover and an outer sleeve; wherein: the first protective cover and the second protective cover are both semi-enclosed structures with one end open, which are formed by two parallel arc plates and end plates located at both ends; end face glue injection sealing grooves are provided on the end plates of the first protective cover and the second protective cover, and longitudinal glue injection sealing grooves are provided at the connection of the arc plates; the openings of the first protective cover and the second protective cover are arranged opposite to each other, and are fixed by the sealant injected into the end face glue injection sealing groove and the longitudinal glue injection sealing groove; the accommodating space formed by the first protective cover and the second protective cover is for placing two side-by-side high-voltage cable intermediate joints; the outer sleeve is sleeved on the outer periphery of the first protective cover and the second protective cover fixed with sealant.

[0004] The existing cable intermediate joints are usually protected by a plastic joint shell. The existing cable intermediate joint shell cannot provide good insulation protection for the cable joints, has low waterproof and insulation protection performance, is inconvenient for operators to install and disassemble the shell, and affects the safety of the cable joint shell. In view of the above problems, a cable intermediate joint shell that is easy to operate is proposed. Utility Model Content

[0006] To achieve the above object, the utility model adopts the following technical scheme: A cable intermediate joint housing that is convenient to operate, including a cable joint, further including a protective housing mechanism and an assembly mechanism. The protective housing mechanism includes a lower protective housing and an upper protective housing. Inner walls of the lower protective housing and the upper protective housing are both fixedly installed with substrates, and insulating plates are fixedly connected to the outer sides of the substrates. Limiting grooves are symmetrically formed on both sides of the lower protective housing and the upper protective housing.

Two convex plates are symmetrically fixedly connected to both ends of the upper protective housing, and the outer sides of the convex plates are slidably installed inside the sliding grooves. The assembly mechanism includes two fixing plates, a limiting plate, and a pull rod. One end of the fixing plate is fixedly connected to one side of the U-shaped plate. A rubber pad is bonded to the outer edge of one end of the limiting plate, and the other end of the limiting plate is clamped inside the limiting groove.

[0007] Preferably, springs are symmetrically fixedly connected to both ends of the limiting plate, and grooves are symmetrically formed on both sides of the fixing plate. One end of the spring is fixedly connected to the inside of the groove.

[0008] Preferably, a through hole is formed through one end of the fixing plate, and an elastic insulating ring is fixedly connected to the inner side wall of the through hole.

Both ends of the lower protective housing 11 are symmetrically fixedly connected with U-shaped plates 15, and a chute 17 is opened on one side of the top end of the U-shaped plate 15. Both ends of the upper protective housing 12 are symmetrically fixedly connected with convex plates 18, and the outside of the convex plate 18 is slidably installed with the inside of the chute 17. Two placing plates 16 are symmetrically fixedly installed on the inner side wall of the lower protective housing 11, and two pressing plates 19 are symmetrically fixedly installed on the inner side wall of the upper protective housing 12. The positions of the placing plate 16 and the pressing plate 19 correspond to each other. The cable joint 3 is located between the placing plate 16 and the pressing plate 19. The top of the upper protective housing 12 is fixedly connected with a lifting rod 13. The lengths of the insulating plate 110 and the substrate 111 are the same, the lengths of the upper protective housing 12 and the lower protective housing 11 are the same, and the lengths of the insulating plate 110 and the substrate 111 are both smaller than the upper protective housing 12.

[0026] The following is a detailed description of the specific settings and functions of this embodiment: when it is necessary to dock and assemble two cables, the cable connector 3 is aligned and placed on the two placement plates 16, and then the two cables are respectively passed through the through holes 27 and assembled with the cable connector 3. After the cables are assembled through the cable connector 3, the staff holds the lifting rod 13 to slide the upper protective shell 12 downward along the slide groove 17 through the convex plate 18 until the bottom of the upper protective shell 12 is in contact with the top of the lower protective shell 11. At this time, the staff holds the pull rod 23 by hand and aligns the limit plate 22 with the limit groove 14, and inserts one end of the limit plate 22 into the limit groove 14 so that the limit plate 22 is clamped and fixed with the limit groove 14, and the upper protective shell 12 and the lower protective shell 11 are limited, which is convenient for the staff to install and disassemble the shell and cable, and convenient for the staff to operate. The innermost side of the upper protective shell 12 and the lower protective shell 11 is an insulating plate 110 with insulating properties, which can well insulate the cable connector 3.

[0027] Embodiment 2: Figure 1 and Figure 5 As shown, the assembly mechanism 2 includes two fixed plates 21, a limiting plate 22 and a pull rod 23, one end of the fixed plate 21 is fixedly connected to one side of the U-shaped plate 15, a rubber pad 24 is bonded to the outer edge of one end of the limiting plate 22, and the other end of the limiting plate 22 is clamped with the inner side of the limiting groove 14, and springs 26 are symmetrically fixedly connected to the two ends of the limiting plate 22. Grooves 25 are symmetrically opened on both sides of the fixed plate 21, one end of the spring 26 is fixedly connected to the inner side of the groove 25, a through hole 27 is opened through one end of the fixed plate 21, and an elastic insulating ring 28 is fixedly connected to the inner wall of the through hole 27, and the two ends of the limiting plate 22 are fixedly installed with the two ends of the pull rod 23.

[0028] The effect achieved by the entire embodiment is that the two cables are respectively passed through the through holes 27 and assembled with the cable connector 3, and the elastic insulating ring 28 on the inner wall of the through hole 27 fits with the outer wall of the cable. The elastic insulating ring 28 can play a waterproof role to prevent rainwater from entering the shell through the through hole 27. After the cable is assembled through the cable connector 3, the staff pulls the pull rod 23 by hand and aligns the limit plate 22 with the limit groove 14, and inserts one end of the limit plate 22 into the limit groove 14 so that the limit plate 22 is clamped and fixed with the limit groove 14. At this time, the limit plate 22 can press the limit groove 14 under the action of the spring 26, thereby limiting the upper protective shell 12 and the lower protective shell 11. At the same time, the rubber pad 24 on its outer edge can seal the gap between the limit plate 22 and the upper and lower protective shells, thereby playing a waterproof and dustproof effect. The inner wall of the through hole 27 is provided with an insulating elastic insulating ring 28, which can well insulate and protect the cable connector 3.

[0029] Usage method and working principle of the device: The outer shell of the cable joint in the middle is composed of a cable joint 3, a protective shell mechanism 1, and an assembly mechanism 2. When it is necessary to dock and assemble two cables, first open the upper protective shell 12, align the cable joint 3 and place it on the two placement plates 16, and then pass the two cables through the through holes 27 respectively to assemble with the cable joint 3. The elastic insulating ring 28 on the inner side wall of the through hole 27 fits against the outer wall of the cable. The elastic insulating ring 28 (such as an elastic insulating snap ring, silicone rubber sealing ring) can play a role in waterproofing to prevent rainwater from entering the shell through the through hole 27;

[0030] After the cables are assembled through the cable joint 3, the staff holds the lifting rod 13 and places the upper protective shell 12 at the top of the lower protective shell 11, and aligns the convex plates 18 at both ends of the upper protective shell 12 with the sliding grooves 17. Slide the upper protective shell 12 downward along the sliding groove 17 through the convex plate 18 until the bottom of the upper protective shell 12 fits against the top of the lower protective shell 11. The pressing plate 19 and the placement plate 16 can press and limit the internal cable joint 3. At this time, the staff holds the pull rod 23 by hand and aligns the limiting plate 22 with the limiting groove 14, and inserts one end of the limiting plate 22 into the limiting groove 14 to make the limiting plate 22 snap and fix with the limiting groove 14. At this time, the limiting plate 22 can press the limiting groove 14 under the action of the spring 26, so as to limit the upper protective shell 12 and the lower protective shell 11. At the same time, the rubber pad 24 on its outer edge can seal the gap between the limiting plate 22 and the upper and lower protective shells, achieving the effect of waterproofing and dustproofing. Through the combination of the protective shell mechanism 1 and the assembly mechanism 2, a good waterproofing and dustproofing effect can be achieved, and at the same time, it is convenient for the staff to install and disassemble the shell and the cable, facilitating the operation of the staff;

[0031] At the same time, the innermost sides of the upper protective shell 12 and the lower protective shell 11 are insulating plates 110 with insulation properties. At the same time, the inner wall of the through hole 27 is provided with an elastic insulating ring 28 with insulation properties, which can well insulate and protect the cable joint 3, improving the insulation protection performance of the shell and the overall use safety.

[0032] The above is only a preferred embodiment of the present invention and does not limit other forms of the present invention. Any person skilled in the art may use the technical content disclosed above to make changes or modifications into equivalent embodiments with equivalent changes and apply them to other fields. However, as long as it does not depart from the technical content of the technical solution of the present invention, any simple modification, equivalent change, and modification made to the above embodiments based on the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
