Description

Technical field:

[0001] The utility model relates to the technical field related to cable connection, and more specifically to a cable docking interface sleeve device. Background technology:

[0002] The conventional operation of the existing cable splicing method is to peel the ends of the two cables, strip the wires, then unfold the copper wires of the two wires, cross them and press them together, or wind the ends of the two wires together, and then put an insulating sleeve on the outside. These are all suitable ways to unfold or bend the copper wires in the wires.

[0003] When the copper wire in some conductors cannot be unfolded, two conductors can be stacked up and down and put into a connecting tube. Then, the connecting tube is deformed with a clamp so that it clamps the two conductors in the connecting tube for fixation. However, this structure is suitable for cables with limited diameters. Cables of a size that cannot be clamped by the clamp cannot be used in this way. Utility model content:

[0004] The purpose of the utility model is to overcome the deficiencies of the prior art and to provide a cable docking interface sleeve device, which can be suitable for cables of various diameters. It presses the ends of the cable conductors entering from the right insertion through hole and the left insertion through hole up and down to achieve connection. The connection operation is convenient and the use effect is good.

[0005] The solution of the utility model to solve the technical problem is:

[0006] A cable docking port sleeve device comprises a connecting cylinder extending transversely, wherein the upper portion of the left end plate of the connecting cylinder is formed with a left insertion through hole, and the lower portion of the right end plate of the connecting cylinder is formed with a right insertion through hole, and both the right insertion through hole and the left insertion through hole are communicated with the inner cavity of the connecting cylinder;

[0007] At least one vertical screw-in hole is formed in the middle of the top plate of the connecting cylinder, and the screw portion of the clamping bolt is screwed in the vertical screw-in hole. The bottom end of the screw portion of the clamping bolt extends into the connecting cylinder and is movably connected to an upper pressure block, and the bottom surface of the upper pressure block faces the middle bottom surface of the internal cavity of the connecting cylinder.

[0008] A locking nut is threadedly connected to the screw rod portion of the clamping bolt, and the bottom surface of the locking nut is pressed against the middle top surface of the top plate of the connecting cylinder.

[0009] The outstanding effects of the utility model are:

[0010] It can be suitable for cables of various diameters. It can press the ends of the cable conductors inserted from the right and left through holes up and down to achieve connection. The connection operation is convenient and the use effect is good. When the upper pressure block is pressed down, the two will be flattened and pressed into contact to a certain extent, thereby increasing the contact area and ensuring the conductive effect and firm fixation.

[0015] For example, see Figures 1 to 4 As shown, a cable docking interface sleeve device includes a laterally extending connecting cylinder 10, a left end plate 20 and a right end plate 30 are fixedly connected to the left end surface and the right end surface of the connecting cylinder 10 by multiple bolts, a sealing gasket is clamped between the left end surface of the connecting cylinder 10 and the left end plate 20, and a sealing gasket is clamped between the right end surface of the connecting cylinder 10 and the right end plate 30.

[0016] A left insertion through hole 21 is formed at the upper portion of the left end plate 20 of the connecting cylinder 10, and a right insertion through hole 31 is formed at the lower portion of the right end plate 30 of the connecting cylinder 10. Both the right insertion through hole 31 and the left insertion through hole 21 are communicated with the internal cavity of the connecting cylinder 10; the left insertion through hole 21 and the right insertion through hole 31 are communicated with and aligned with the through holes on the corresponding sealing gasket.

[0017] The left insertion through hole 21 and the right insertion through hole 31 in this embodiment are both semicircular through holes.

[0018] The middle of the top surface of the connecting cylinder 10 is a horizontal surface, and two vertical screw holes 11 are formed in the middle of the top plate of the connecting cylinder 10. The screw parts of the two clamping bolts 40 are screwed in the vertical screw holes 11. The bottom ends of the screw parts of the clamping bolts 40 extend into the connecting cylinder 10 and are movably connected to the same upper pressing block 42. The bottom surface of the upper pressing block 42 faces the middle bottom surface of the internal cavity of the connecting cylinder 10. The top surface of the upper pressing block 42 is an arc surface, which matches the top surface of the internal cavity of the connecting cylinder 10.

[0019] Furthermore, the bottom surface of the upper pressing block 42 is an arc-shaped surface.

[0020] A locking nut 43 is threadedly connected to the screw rod of the clamping bolt 40 , and the bottom surface of the locking nut 43 is pressed against the middle top surface of the top plate of the connecting cylinder 10 .

[0021] A guide protrusion 12 extending upward is formed on the left end bottom surface of the internal cavity of the connecting cylinder 10 at the right end of the left insertion hole 21, the top surface of the guide protrusion 12 is on the same horizontal plane as the bottom surface of the left insertion hole 21, and an inclined surface is formed on the upper right end of the guide protrusion 12.

[0022] A right guide protrusion 13 extending downward is formed on the right end top surface of the internal cavity of the connecting cylinder 10 at the left end of the right insertion hole 31, and the bottom surface of the right guide protrusion 13 is on the same horizontal plane as the top surface of the right insertion hole 31, and an inclined surface is formed on the left end bottom surface of the right guide protrusion 13.

[0023] The bottom surface of the inner cavity of the connecting cylinder 10 is formed with an oblique portion 1 extending obliquely from right to left and upward, and the left end of the oblique portion 1 is formed on the right end surface of the guiding protrusion 12 .

[0024] When this embodiment is used, the outer walls of the ends of the two cables are firstly peeled to expose the inner wire ends, and then the wires of the two cables are respectively inserted into the inner cavity from the left insertion hole 21 and the right insertion hole 31. The wire of the left insertion hole 21 is transported to the right along the top surface of the guide protrusion 12 and is below the bottom surface of the upper pressing block 42, while the wire of the right insertion hole 31 moves to the left along the bottom surface of the right end of the inner cavity, and is limited by the bottom surface of the right guide protrusion 13 to prevent it from tilting upward, and then , the guide tilts upward along the oblique portion 1, and finally moves to the bottom of the cable conductor extended from the left end. At this time, the upper conductor corresponds to the lower conductor, and then, the two locking nuts 43 are loosened, and the two clamping bolts 40 are rotated to make the upper pressing block 42 descend and press down, so that the two superimposed wire parts are pressed against each other and clamped between the bottom surface of the upper pressing block 42 and the bottom surface of the internal cavity to achieve clamping and fixing. During this clamping process, the two wire parts are deformed, flattened and pressed against each other, so that the contact area is greatly increased to ensure the conductive effect.

[0025] After the clamping bolt 40 is rotated into place, the locking nut 43 is tightened to achieve clamping and fixing. The fixing is firm and the clamping area is large, thereby ensuring the conductive effect.

[0026] After the connection is completed, you only need to cover the outer surface with an insulating material layer for insulation protection and sealing to ensure that the two cables are firmly connected and have good conductivity.

[0027] The above implementation modes are only used to illustrate the present invention, but not to limit the present invention. Ordinary technicians in the relevant technical field can make various changes and modifications without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions also belong to the scope of the present invention. The scope of patent protection of the present invention should be limited by the claims.
