Description

Technical Field

[0001] The utility model relates to the technical field of cable wires, in particular to a cable wire joint that can be quickly assembled. Background Technique

[0002] Cable wires are essential items in daily life and are mainly used for power transmission; cable wires are mainly composed of an insulating sheath processed from PVC plastic and various specifications of copper wires that are stranded together. During the use or maintenance of cable wires, it is often necessary to connect the two ends of two cable wires together. Sometimes, to save the cable wire connection time, generally, the cores at both ends of the two cable wires are wound together, and then the interface is wound and fixed with insulating tape. Although this method can quickly connect the two cable wires together, after the insulating tape is used for a long time, it is extremely easy to come loose, resulting in the interface at both ends of the two cable wires getting damp and short-circuiting. Moreover, for relatively thick cable wires, the insulating tape is not very practical. Content of the Utility Model

[0003] By providing a cable wire joint that can be quickly assembled in the embodiments of the present application, the cooperation of the upper limiting plate and the lower limiting plate can quickly fix two cable wires together, and the later disassembly and assembly are also relatively convenient. The setting of the sealing ring avoids the dampness and short-circuiting at the connection of the two cable wires. By setting it in different specifications and sizes, it can be applicable to different thicknesses of cable wires, and the practicability is relatively high.

[0004] The embodiments of the present application provide a cable wire joint that can be quickly assembled, including an upper end cover and a lower end cover. Both the upper end cover and the lower end cover are set to be arc-shaped and are symmetrically arranged between the upper end cover and the lower end cover; upper pads are respectively fixedly connected to the front and rear sides of the upper end cover, and the bottom end surface of the upper pad is flush with the bottom end surface of the upper end surface; lower pads are respectively fixedly connected to the front and rear sides of the lower end cover, and the upper end surface of the lower pad is flush with the upper end surface of the lower end cover; threaded holes are opened on both the upper pad and the lower pad, and the upper end cover and the lower end cover are fixed by installing bolts;

[0005] A lower limiting plate is fixedly connected to the middle of the inner wall of the lower end cover, and it is set to be arc-shaped; an upper limiting plate is arranged above the lower limiting plate, and it is set to be arc-shaped. The upper limiting plate and the lower limiting plate can be assembled into a circle; a limiting rod is installed on the outer wall above the upper limiting plate, and the upper side of the limiting rod passes through the upper side of the upper end cover and extends to its outside. The bottom side of the limiting rod is rotatably connected to the upper limiting plate;

[0006] The upper limiting plate is made of an aluminum-magnesium alloy plate, and its thickness is 5-7 mm.

[0007] Furthermore, there are at least two limiting rods, which are rotatably connected to the left and right sides of the upper side of the upper limiting plate; the limiting rods are provided as threaded rods, and threaded through holes are opened on the upper end cover, and the limiting rods are rotatably connected to the upper end cover through threads.

[0008] Furthermore, the bottom side of the upper limiting plate is in contact with the upper side of the lower limiting plate and is not fixed.

[0009] Furthermore, a first sealing ring and a second sealing ring are respectively installed on the left and right sides of the inner wall of the lower end cover;

[0010] Both the first sealing ring and the second sealing ring are made of hard rubber. External threads are provided on the outer walls of the first sealing ring and the second sealing ring, and internal threads are provided on the left and right sides of the inner wall of the lower end cover.

Similarly, the length of the internal thread opened on the right side of the inner wall of the lower end cover is 7 - 9 cm away from the right side of the lower limiting plate.

[0013] Furthermore, internal threads are also opened on the left and right sides of the inner wall of the upper end cover, and their lengths are the same as those of the internal threads on the inner wall of the lower end cover.

[0028] Both the upper end cover 10 and the lower end cover 20 are arranged in an arc shape and are symmetrically arranged between the upper end cover 10 and the lower end cover 20; upper pads 11 are respectively fixedly connected to the front and rear sides of the upper end cover 10, and the bottom end surface of the upper pad 11 is flush with the bottom end surface of the upper end surface 10; lower pads 21 are respectively fixedly connected to the front and rear sides of the lower end cover 20, and the upper end surface of the lower pad 21 is flush with the upper end surface of the lower end cover 20;

[0029] A lower limiting plate 50 is fixedly connected to the middle of the inner wall of the lower end cover 20, which is arranged in an arc shape; an upper limiting plate 51 is arranged above the lower limiting plate 50, which is arranged in an arc shape, and the upper limiting plate 51 and the lower limiting plate 50 can be assembled into a circle; a limiting rod 52 is installed on the outer wall above the upper limiting plate 51, the upper side of the limiting rod 52 passes through the upper side of the upper end cover 10 and extends to its outside, and the bottom side of the limiting rod 52 is rotatably connected to the upper limiting plate 51;

[0030] The upper limiting plate 51 is made of an aluminum-magnesium alloy plate with a thickness of 5-7 mm. As the limiting rod 52 rotates, the upper limiting plate 51 can be pushed downwards. By the resistance of the lower limiting plate 50, the middle position of the upper limiting plate 51 is concave, so that the core 32 of the first cable 30 and the core 42 of the second cable 40 are fixed between the upper limiting plate 51 and the lower limiting plate 50.

[0031] There are at least two limiting rods 52, which are rotatably connected to the upper left and right sides of the upper limiting plate 51; the limiting rod 52 is arranged as a threaded rod, and a threaded through hole 12 is opened on the upper end cover 10, and the limiting rod 52 is rotatably connected to the upper end cover 10 through a thread.

[0032] The bottom side of the upper limit plate 51 is in contact with the upper side of the lower limit plate 50 without being fixed, so that the upper limit plate 51 can move up and down along with the limit rod 52, thereby fixing the cores of the two cable wires.

[0033] Threaded holes are provided on both the upper backing plate 11 and the lower backing plate 21, and the upper end cover 10 and the lower end cover 20 are fixed by installing bolts.

[0034] On the left and right sides of the inner wall of the lower end cover 20, a first sealing ring 31 and a second sealing ring 41 are respectively installed;

[0035] Both the first sealing ring 31 and the second sealing ring 41 are made of hard rubber. External threads are provided on the outer walls of the first sealing ring 31 and the second sealing ring 41, and internal threads are provided on the left and right sides of the inner wall of the lower end cover 20. The first sealing ring 31 and the second sealing ring 41 are respectively rotatably connected to the lower end cover 20 through threads.

[0036] A first cable wire 30 is installed inside the first sealing ring 31, and a second cable wire 40 is installed inside the second sealing ring 41; the first cable wire 30 and the second cable wire 40 are respectively installed in an interference fit manner with the first sealing ring 31 and the second sealing ring 41.

[0037] The length of the internal thread provided on the left side of the inner wall of the lower end cover 20 is 7 - 9 cm away from the left side of the lower limit plate 50. Similarly, the length of the internal thread provided on the right side of the inner wall of the lower end cover 20 is 7 - 9 cm away from the right side of the lower limit plate 50.

The first sealing ring 31 and the second sealing ring 41 are also respectively rotatably connected to the upper end cover 10 through threads;

[0039] That is, after the first core 32 and the second core 42 are fixed by the upper limit plate 51 and the lower limit plate 50, the first cable wire 30 is sleeved inside the first sealing ring 31, and the second cable wire 40 is sleeved inside the second sealing ring 41. The first sealing ring 31 and the second sealing ring 41 are respectively pulled, and are respectively placed on the left and right sides between the upper end cover 10 and the lower end cover 20. Then, the first sealing ring 31 and the second sealing ring 41 are screwed to fix them between the upper end cover 10 and the lower end cover 20, thereby realizing the sealing between the upper end cover 10, the lower end cover 20 and the first cable wire 30, the second cable wire 40.

[0043] When the embodiment of the present application actually operates, remove the bolts and disassemble the upper end cover 10 and the lower end cover 20. Remove a section of the insulating sleeve from the first cable 30 and the second cable 40 respectively to expose the first wire core 32 and the second wire core 42. The first cable 30 and the second cable 40 pass through the first sealing ring 31 and the second sealing ring 41 respectively. Place the first wire core 32 and the second wire core 42 on the lower limit plate 51 and then install the upper end cover 10 (note to avoid pulling the first cable 30 and the second cable 40). Then screw the limit rod 52. As the limit rod 52 rotates, push down the upper limit plate 51. Through the resistance of the lower limit plate 50, the middle position of the upper limit plate 51 is concave, so as to fix the first wire core 32 and the second wire core 42 between the upper limit plate 51 and the lower limit plate 50. Then pull the first sealing ring 31 and the second sealing ring 32 respectively and place them on the left and right sides between the upper end cover 10 and the lower end cover 20. Then screw the first sealing ring 31 and the second sealing ring 32 to fix them between the upper end cover 10 and the lower end cover 20, so as to realize the sealing between the upper end cover 10, the lower end cover 20 and the first cable 30, the second cable 40.

[0045] It should be noted that the deformed upper limit plate can be restored to its original state manually with the help of tools (such as pliers).

[0046] The above is only the preferred embodiment of the present invention and is not used to limit the present invention.
