Description

Technical Field

[0001] This utility model relates to the field of communication connection technology, specifically to an easy-to-install drone communication connection cable fastening device. Background Technology

[0002] With the widespread application of drone technology in fields such as inspection, logistics, and emergency rescue, higher demands are being placed on the reliability and ease of maintenance of their internal communication systems. Multiple communication cables are typically used to transmit signals between drone onboard equipment. These cables endure continuous vibration and instantaneous impacts during frequent takeoffs and landings and high-maneuverability flight, while rapid disassembly and assembly are required during maintenance to minimize ground preparation time. Currently, cable connection devices suitable for operation in confined spaces must balance mechanical strength and operational efficiency. Especially in field or emergency scenarios, achieving rapid, accurate positioning and secure connection of cable joints has become a key technical aspect for improving the maintenance efficiency of drone systems.

[0003] Currently available communication cable fastening devices typically rely on tightening / loosening threads to achieve fixation and separation. The disassembly and assembly process requires multiple rotations and the use of tools such as wrenches, resulting in a single maintenance operation taking more than 3 minutes. This cannot meet the high-frequency maintenance needs of drones. In addition, the full-circumference thread structure is prone to stripping failure after repeated disassembly and assembly. Furthermore, conventional cable fastening devices use a single fixing mode (such as only crimping the outer sheath or only clamping the wire core), which leads to stress concentration under force, resulting in insufficient tensile strength at the connection. Actual tests show that traditional structures exceed the displacement limit under a tensile force of 80N, making it difficult to withstand the high-frequency vibration and accidental pulling during drone flight.

[0025] In this embodiment, preferably, the quick-connect mechanism 102 further includes a female screw block 206 and a male quick-connect block 303. The female screw block 206 is fixedly installed on the side of the female quick-connect block 106 away from the quick-connect female head 201, and the female screw block 206 is screwed inside the connecting block 101.

[0026] The above scheme achieves a threaded connection between the quick-connect mechanism and the connecting block through the female thread block; the male quick-connect block supports the quick-connect male connector assembly.

[0027] In this embodiment, preferably, a female guide block 301 is fixedly installed inside the female quick-connect block 106, a guide pin 205 is fixedly installed on one side of the female guide block 301, and a first clamping plate 302 is fixedly installed on the side of the female guide block 301 away from the guide pin 205.

[0028] The above scheme integrates the installation of guide pins and signal transmission through the mother guide block; and achieves one-time clamping and fixing of the conductor core through the first clamping plate.

[0029] In this embodiment, preferably, a quick-connect male connector 304 is fixedly installed on one side of the quick-connect block 303, a retaining bead 305 is movably installed on the outer side of the quick-connect male connector 304, a spring 306 is sleeved on the side of the quick-connect male connector 304 near the retaining bead 305, and a slide cylinder 401 is movably installed on the outer side of the spring 306 and the retaining bead 305.

[0030] The above scheme achieves the insertion action through the quick-connect male connector; the self-locking function is achieved through the cooperation of the locking ball and the spring; and the retraction and unlocking of the locking ball is controlled by the slide cylinder.

[0031] In this embodiment, preferably, the quick-connect male connector 304 has a male guide block 402 inside, the male guide block 402 has a guide groove 403 in the middle, and a positioning block 404 is fixedly installed on the side of the male guide block 402 near the guide groove 403.

[0032] The above scheme provides a guide block for insertion; guide grooves enable precise sliding of the guide pins; and positioning blocks limit the axial position of the insertion.

[0033] In this embodiment, preferably, the male guide block 402 is engaged in the slot 203, the guide pin 205 is engaged in the guide groove 403, and the positioning block 404 is engaged in the positioning groove 204.

[0034] The above scheme achieves anti-misalignment during insertion by engaging the male guide block with the slot; and achieves radial self-correction by cooperating with the guide groove and the guide pin.

[0035] In this embodiment, preferably, the male guide block 402 is fixedly installed inside the male quick-connect block 303, and a second clamping plate 501 is fixedly installed on the side of the male guide block 402 away from the guide groove 403. The male screw block 406 is screwed into the connecting block 101.

[0036] The above scheme achieves structural reinforcement by having the male conductor block penetrate the male quick-connect block; it also achieves secondary clamping reinforcement of the conductor core by using the second clamping plate; and it achieves threaded sealing connection between the male quick-connect mechanism and the connecting block by using the male screw block.

[0037] In this embodiment, an easy-to-install drone communication cable fastening device is used by first fitting the tightening screw 105 and the connecting block 101 assembly onto the outside of the two sections of the connecting cable, respectively, cutting the outer sheath of the communication cable to expose the internal communication core. The core conductor is quickly fixed by the elastic clamping structure of the first clamping plate 302 and the second clamping plate 501 in the female quick-connect block 106 and the male quick-connect block 303 inside the connecting block 101. Then, the outer sheath is inserted into the annular clamping space formed by the clamping sleeve 103 and the tightening screw 104. When the tightening screw 105 is rotated in one direction, its internal gradually changing pitch screw... The differential speed movement of the equidistant threads on the outer wall of the shrinking screw 104 drives the radial contraction of the six-lobed split structure of the shrinking screw 104 to generate a uniform clamping force to achieve a press-fit seal on the outer sheath. At the same time, the female screw block 206 and the male screw block 406 are quickly screwed into each other through the precision threaded interfaces on both sides of the connecting block 101 to complete the full sealing protection at the connection point. When the quick-connect mechanism 102 performs the connection, manually pushing the outer slide cylinder 401 of the quick-connect male head 304 compresses the spring 306, causing the retaining ball 305 to retract and release the locking state. During the insertion of the quick-connect male head 304 along the direction of the slot 203 of the quick-connect female head 201, the male guide block 402 positions the block. The planar engagement of 404 with slot 203 and positioning groove 204 forms an axial limiting guide. The linear sliding fit of female guide block 301 guide pin 205 and male guide block 402 guide groove 403 forms a radial positioning guide. The dual guide assembly ensures self-correction alignment during the insertion process through orthogonal direction constraints, enabling rapid insertion operation under non-direct viewing conditions. When the slide cylinder 401 is released after insertion, the spring 306 resets and pushes the slide cylinder 401 forward, forcing the retaining ball 305 to radially pop out and embed into the annular retaining groove 202 of the quick connector female head 201, forming a mechanical interlock and achieving instantaneous locking of the connector. During disassembly, only one hand is needed to pull the slide cylinder 401 backward. 1. The quick-connect male connector 304 and quick-connect female connector 201 can be separated without damage by disengaging the clasp 305 from the clasp slot 202. This device achieves quick assembly and disassembly of the communication line connection by hand through the synergistic effect of the threaded quick-connect of the clamping structure, the double-guided blind insertion design of the quick-connect mechanism 102, and the instantaneous locking of the spring 306 and clasp 305. During this process, the signal is transmitted through the metal conductive path composed of the clamping plate and the guide block. The surface contact between the guide pin 205 and the guide slot 403 ensures the stability of the signal transmission. The overall structure maintains high conductivity while improving both assembly and disassembly efficiency and tensile strength.
