Detailed implementation mode

[0020] In the following, embodiments of the quickly connectable cable joint of the present utility model will be described with reference to the accompanying drawings.

[0021] Figures 1-4 A quickly connectable cable joint showing an embodiment of the present utility model includes a male docking head 1: A female docking head 2 is inserted on the right side of the male docking head 1. A sealing ring 11 is sleeved on the right side of the male docking head 1. An annular groove 12 adapted to the sealing ring 11 is opened on the left side of the female docking head 2. Cables 3 are electrically connected to opposite ends of the male docking head 1 and the female docking head 2. A locking assembly 4 is arranged on the surface of the male docking head 1. The locking assembly 4 includes two fixed plates 41 respectively fixedly connected to the front side and the rear side of the male docking head 1. A clamping arm 42 is arranged in the inner cavity of the two fixed plates 41. A rectangular slot 9 is opened on the front side of the clamping arm 42. A torsion spring 10 is arranged in the inner cavity of the rectangular slot 9. The torsion spring 10 is sleeved on the surface of the rotating column 43. Through the combined use of the rectangular slot 9 and the torsion spring 10, an elastic twisting effect is exerted on the clamping arm 42, enabling the clamping arm 42 to actively rotate and enabling the clamping arm 42 to stably engage in the inner cavity of the limiting clamping groove 8, improving the connection stability between the male docking head 1 and the female docking head 2. A limiting sleeve 5 is rotatably connected to the surface of the female docking head 2. A limiting arc plate 6 is fixedly connected to the right end of the clamping arm 42. Reserved openings 7 adapted to the limiting arc plate 6 are opened at the top and the bottom of the limiting sleeve 5. The inner wall of the reserved opening 7 is an arc surface. Through the combined use of the limiting sleeve 5, the limiting arc plate 6 and the reserved opening 7, the clamping arm 42 is limited and fixed, enabling the clamping arm 42 to stably fit on the surface of the male docking head 1, and further enabling the arc-shaped clamping block 44 to stably engage in the inner cavity of the arc-shaped clamping groove 45, performing limit locking on the connection between the male docking head 1 and the female docking head 2, thereby enabling the male docking head 1 and the female docking head 2 to be quickly connected while ensuring connection stability. Limiting clamping grooves 8 adapted to the limiting arc plate 6 are opened at the front side and the rear side of the inner cavity of the limiting sleeve 5. A rotating column 43 penetrates through the left side of the top of the fixed plate 41. The rotating column 43 is rotatably connected to the fixed plate 41. An arc-shaped clamping block 44 is fixedly connected to the side of the clamping arm 42 close to the male docking head 1. Arc-shaped clamping grooves 45 adapted to the arc-shaped clamping block 44 are opened at the front side and the rear side of the female docking head 2.

[0022] Working principle: When the utility model is used, the user inserts the docking male head 1 into the inner cavity of the docking female head 2, and then the user flips the two clamping arms 42, so that the clamping arms 42 drive the arc-shaped clamping block 44 to be clamped in the inner cavity of the arc-shaped clamping groove 45, and the clamping arms 42 drive the limiting arc plate 6 to be clamped in the inner cavity of the reserved opening 7, and at the same time compress the torsion spring 10, and then the user rotates the limiting sleeve 5 so that the limiting arc plate 6 enters the inner cavity of the limiting sleeve 5, and after the limiting clamping groove 8 moves to the surface of the limiting arc plate 6, the clamping arms 42 are twisted under the elastic force of the torsion spring 10 The limiting arc plate 6 is driven to engage in the inner cavity of the limiting slot 8 to limit and lock the clamping arm 42. When disassembly is required, the user presses the two clamping arms 42 so that the clamping arms 42 drive the limiting arc plate 6 to disengage from the inner cavity of the limiting slot 8, and then rotates the limiting sleeve 5 so that the reserved opening 7 reaches the clamping arm 42. Under the elastic force of the torsion spring 10, the clamping arm 42 drives the limiting arc plate 6 to disengage from the inner cavity of the limiting sleeve 5. At the same time, the clamping arm 42 drives the arc block 44 to disengage from the inner cavity of the arc slot 45. Finally, the docking male head 1 and the docking female head 2 can be separated.

[0023] To sum up: the quick-connect cable connector, by plugging the docking male head 1 and the docking female head 2 together, makes the two cables 3 electrically connected, and then through the cooperation of the locking component 4 and the limit sleeve 5, the connection position of the docking male head 1 and the docking female head 2 is limited and locked, so as to achieve the purpose of fast connection and stable and reliable plug-in.
