DETAILED DESCRIPTION

[0026] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the protection scope of the present invention.

[0027] like Figure 1-5The present embodiment shows a docking assembly of a glass fiber cable sleeve 5, which is suitable for use in scenarios where the connection stability of the cable sleeve 5 is not required. The docking assembly includes an abutment 4 and a docking body. The abutment 4 is detachably fixed to the outer circumferential surfaces of both ends of the cable sleeve 5 by screws. According to the actual design, two or more abutments 4 are arranged at intervals in the circumferential direction of the cable sleeve 5. The aforementioned docking body has a central axis. The docking body includes a disc 1 and a connecting frame. The two discs 1 are arranged at intervals in the direction of the central axis. The sides of the two discs 1 that are close to each other form a relative surface 11. The connecting member 3 is connected between the two discs 1 so that the two discs 1 form an integral structure. The disc 1 is coaxially processed with an insertion hole 14. The inner diameter of the insertion hole 14 is adapted to the outer diameter of the cable sleeve 5 for passing the cable sleeve 5. The inner circumferential wall of the insertion hole 14 is processed with an avoidance groove 13 corresponding to the abutment 4 arranged on the cable sleeve 5. One end of the cable bushing 5 can be inserted into the insertion hole 14 to enter the space between the two disk bodies 1, and the abutment member 4 is simultaneously inserted into the avoidance groove 13. Through the above structural design, the two cable bushings 5 ​​have a docking state in which they are inserted into the insertion holes 14 on the corresponding sides and docked with each other between the two disk bodies 1. In this docking state, the abutment member 4 is located between the two disk bodies 1.

[0028] A locking surface 12 is formed on the opposite surface 11 of the aforementioned disk body 1 corresponding to the abutment 4. The locking surface 12 of the present embodiment is a spiral surface formed around the central axis. The two terminal ends of the locking surface 12 have a height difference in the direction of the central axis. In the aforementioned docking state, by rotating the docking body, the docking body has a locked state in which the locking surface 12 and the abutment 4 abut against each other, and by reversing the docking body, the locking surface 12 and the abutment 4 are separated from each other. Through the above-mentioned structural design, in this locked state, the two cable sleeves 5 are driven to move closer to each other and restricted to move in the direction of the central axis, thereby being locked. In the aforementioned unlocked state, the two cable sleeves 5 are unlocked.

[0029] In this embodiment, of the two locking ends of the locking surface 12, the locking end close to the other side of the disk body 1 is defined as the first end, and the locking end away from the other side of the disk body 1 is defined as the second end. The aforementioned avoidance groove 13 is arranged at a position close to the second end. Through the above structural design, when the cable sleeve 5 is inserted into the insertion hole 14, the abutment member 4 is inserted between the two disk bodies 1 through the avoidance groove 13 and away from the locking surface 12.

[0030] In this embodiment, the docking assembly includes a partition 6 inserted between the two disk bodies 1. A docking hole 63 is processed on the partition 6 corresponding to the insertion hole 14. Elastic sealing members 62 are arranged around the docking hole 63 on the two sides of the partition 6 facing the disk body 1. The elastic sealing member 62 is an annular rubber sealing gasket. In the aforementioned docking state, the end face of the cable sleeve 5 abuts against the elastic sealing member 62 to seal the end face of the cable sleeve 5. In the above structural design, the cable passes through the docking hole 63 so as to be able to be inserted into the two oppositely connected cable sleeves 5. In this embodiment, a positioning groove 31 is processed at a predetermined position on the connector 3. A positioning rod 61 is installed on the partition 6. When the partition 6 is inserted between the two disk bodies 1, the positioning rod 61 is inserted into the positioning groove 31 at the corresponding position, thereby fixing the partition 6 on the connector 3 in a detachable manner.

[0031] In this embodiment, a guide tube 2 is formed on the opposite sides of the two disk bodies 1. The guide tube 2 extends in the direction of the central axis. A guide channel 21 adapted to the cable sleeve 5 is formed inside the guide tube 2. The guide channel 21 is connected to the insertion hole 14. The cable sleeve 5 is guided by the guide channel 21 so as to smoothly enter the insertion hole 14. Among them, a wire groove 22 extending in the direction of the central axis and connected to the avoidance groove 13 is formed on the side wall of the guide tube 2 corresponding to the avoidance groove 13. The wire groove 22 forms an insertion port on the end face of the guide tube 2 away from the disk body 1. When the cable sleeve 5 is inserted into the guide channel 21, the abutment member 4 is inserted into the wire groove 22 through the insertion port.

[0032] When in use, the separator 6 is inserted between the two disk bodies 1, and the positioning rod 61 on the separator 6 is inserted into the positioning groove 31, so that the separator 6 is positioned at the current position. The two cable sleeves 5 are inserted into the insertion holes 14 of the disk bodies 1 on both sides, and docked to the elastic seal 62 of the separator 6, so that the two cable sleeves 5 form a docking state between the two disk bodies 1. The docking body is rotated toward one side and the locking surface 12 is driven to move, so that the locking surface 12 and the abutment 4 abut against each other, and then the cable sleeves 5 on both sides are pushed closer to each other, so as to achieve the locking of the two cable sleeves 5. When docking, the end face of the cable sleeve 5 abuts against the elastic seal 62, so that the sealing of the two cable sleeves 5 when docking can be effectively improved. By rotating the docking body in the opposite direction, the locking surface 12 and the abutment 4 are disengaged from each other, so that the two cable sleeves 5 can be unlocked. The combination of the above-mentioned methods can realize the rapid locking and unlocking of two mutually docked cable sleeves 5, and the disassembly and assembly are simple and convenient, which effectively improves the assembly efficiency of the cable sleeves 5 and has strong practicality.

Any equivalent structure or equivalent process transformation made using the contents of the present invention specification, or directly or indirectly applied in other related technical fields, are also included in the patent protection scope of the present invention.
