Description

Technical Field

[0001] The utility model relates to the technical field of battery connecting wires, in particular to a battery connecting wire harness with a quick-release socket. Background Art

[0002] One end of the battery connection harness is connected to the battery, and the other end is connected to the electrical device. The connection harness enables the battery to power the device. The existing battery connection harness is inconvenient to connect and is easily disconnected after being pulled after connection, so some battery connection harnesses use a snap-on connection method.

[0003] In the related art, the common snap-on connection method is generally structured with a hook rod and a protrusion on the other joint. When the snaps are docked, the hook rod is engaged with the protrusion to prevent them from falling off. However, the snaps are made of plastic, and in order for the hook rod to be able to tilt up, their structural strength is limited. When the plugs of the wiring harnesses of new energy vehicles are disassembled or spliced, the snaps are prone to breakage, resulting in a loose connection between the wiring harness plugs. In addition, the hook rod connection method is also prone to separation due to vibration and other factors, resulting in poor contact. Utility Model Content

Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Example:

[0022] See also Figure 1-4 The utility model provides a technical solution: a battery connection harness with a quick-release socket, comprising a sleeve 2, a limiting groove 6 is provided on the surface of the sleeve 2, the limiting groove 6 is bent, and the limiting groove 6 is approximately J-shaped, which can smoothly clamp the protrusion 12;

[0023] The plug 5, the sleeve 2 is connected to the plug 5, the sleeve 2 and the plug 5 are both connected to the wire 3, the surface of the plug 5 is rotatably connected to the fixed tube 1, the inner wall of the fixed tube 1 is provided with a protrusion 12, and the protrusion 12 is clamped with the limit groove 6;

[0024] When the fixing tube 1 is rotated, the protrusion 12 can be controlled to move along the limiting groove 6 to ensure that the protrusion 12 moves to the upper right side of the limiting groove 6, so as to ensure that the fixing tube 1 and the sleeve 2 are stably stuck and ensure that the sleeve 2 and the plug 5 will not be separated after being plugged in;

[0025] The sleeve 16 is threadedly connected to the plug 5, and a push rod 11 is inserted into the sleeve 16. A spring 10 is provided between the left end of the push rod 11 and the plug 5. The spring 10 pushes the push rod 11 to support the fixed tube 1 to keep the protrusion 12 on the fixed tube 1 and the limiting groove 6 in a clamping state, which can avoid the fixed tube 1 from moving automatically and prevent the protrusion 12 from separating from the limiting groove 6.

[0026] In this embodiment, if Figure 1 As shown, a sealing tube 7 is fixedly connected to the surface of the sleeve 2, and the sealing tube 7 is sleeved on the surface of the fixed tube 1. A sealing ring 8 is provided between the sealing tube 7 and the fixed tube 1. The sealing ring 8 is flexible. When clamped by the fixed tube 1 and the sealing tube 7, the sealing ring 8 is deformed to fill the gap between the fixed tube 1 and the sealing tube 7, thereby enhancing the sealing effect.

[0027] In this embodiment, if Figure 3 As shown, the inner wall of the sealing tube 7 is provided with an annular groove 15, and the sealing ring 8 is installed inside the annular groove 15. The annular groove 15 limits the sealing ring 8 to prevent the sealing ring 8 from separating from the sealing tube 7. When the sealing tube 7 is sleeved on the fixed tube 1, the sealing ring 8 will not slide.

[0028] In this embodiment, if Figure 1 and Figure 3 As shown, a threaded hole 9 is provided on the right side of the sleeve 2, and the sleeve 16 is screwed into the threaded hole 9. The threaded hole 9 can limit the movement of the spring 10, ensuring that the spring 10 can apply elastic force to the anti-slip block 14, so that the anti-slip block 14 can stably press and fix the left end face of the tube 1.

[0029] In this embodiment, if Figure 2As shown, a retaining ring 4 is provided on the surface of the plug 5, and the retaining ring 4 abuts against the fixed tube 1.

[0031] Specifically, when in use, when the plug 5 is inserted into the sleeve 2, the fixed tube 1 is rotated to drive the protrusion 12 to align with the limiting groove 6, and the plug 5 is inserted into the sleeve 2, and the protrusion 12 moves to the inside of the limiting groove 6. The fixed tube 1 is rotated to control the protrusion 12 to move to the upper right side of the limiting groove 6. At this time, the spring 10 moves the push rod 11 to support the fixed tube 1, ensuring that the fixed tube 1 will not actively move to the left, thereby preventing the protrusion 12 from separating from the limiting groove 6;

[0032] After the sealing tube 7 is sheathed around the fixing tube 1 , the sealing ring 8 can be used to seal the fixing tube 1 , thereby preventing dust and water from entering the plug 5 and the sleeve 2 , preventing short circuits, and avoiding fires in the wires 3 .
