DETAILED DESCRIPTION
[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. 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.
[0024] Please refer to Figure 1-Figure 5 The utility model provides a technical solution: an electrical connector, including a male connector 1 and a female connector 2, the outer surface of one end of the male connector 1 close to the female connector 2 is rotatably connected with a rotating ring 3, the outer surface of the end of the female connector 2 close to the male connector 1 is fixedly sleeved with a fixing ring 4, the outer surface of the rotating ring 3 close to the female connector 2 is symmetrically provided with two sliding grooves, the interiors of the two sliding grooves are slidably connected with two slide plates 6, the outer surfaces of the two slide plates 6 are fixedly connected with connecting plates 7, the outer surfaces of the two connecting plates 7 away from the slide plates 6 are fixedly connected with limiting blocks 8, the outer surfaces of the two connecting plates 7 opposite to each other are fixedly connected with two springs 9, the outer surface of the fixing ring 4 is provided with two arc holes 5 symmetrically arranged up and down, and the outer surfaces of the two sides of the two arc holes 5 are provided with rectangular holes 17. In this embodiment, the male connector 1 is plugged into the female connector 2 so that the rotating ring 3 can be connected to the female connector 2. The limit block 8 on the moving ring 3 corresponds to the arc hole 5 on the surface of the fixed ring 4. When the limit block 8 corresponds to the arc hole 5, the outer surface of the fixed ring 4 squeezes the limit block 8, driving the connecting plate 7 to deform the spring 9. When the rotating ring 3 contacts the fixed ring 4, the limit block 8 passes through the arc hole 5, and drives the connecting plate 7 under the elastic force of the spring 9 to reset the limit block 8, so that the limit block 8 hooks the fixed ring 4 away from the other end of the rotating ring 3. Under the action of the limit block 8, the male connector 1 and the female connector 2 are prevented from being separated due to external force, thereby increasing the stability of the connection between the male connector 1 and the female connector 2. When the male connector 1 and the female connector 2 need to be disassembled, the rotating ring 3 is rotated, and the rotating ring 3 drives the limit block 8 to rotate to the position of the rectangular hole 17, thereby releasing the limit on the fixed ring 4, and the male connector 1 and the female connector 2 can be directly disassembled from the rectangular groove 16.
[0025] A pin 10 is provided inside the male connector 1, a hole 14 adapted to the pin 10 is provided inside the female connector 2, and a wire spring 11 is provided inside the female connector 2. In this embodiment, when the male connector 1 is inserted into the female connector 2, the pin 10 is inserted into the hole 14 and into the wire spring 11.
[0026] The top outer surface and the bottom outer surface of the female connector 2 are both threaded with a threaded rod 12, and the opposite outer surfaces of the two threaded rods 12 are rotatably connected with a clamping plate 13. In this embodiment, the threaded rod 12 is rotated, and the threaded rod 12 drives the clamping plate 13 to move downward, so that the clamping plate 13 drives the wire spring 11 to fit the pin 10.
[0027] The outer surface of the pin 10 is fixedly connected with a plurality of raised ribs 15 in a circular array, and the interior of the female connector 2 is provided with a plurality of rectangular grooves 16 in a circular array around the insertion hole 14. The raised ribs 15 are adapted to the rectangular grooves 16. In this embodiment, the raised ribs 15 are inserted into the rectangular grooves 16 to limit the pin 10 and prevent the pin 10 from circumferential rotation.
[0028] The top inner surface and the bottom inner surface of the female connector 2 are fixedly connected with a telescopic rod, and the other ends of the telescopic rod are fixedly connected to two clamps 13 respectively. In this embodiment, when the threaded rod 12 is rotated, the clamps 13 are driven to move, so that the telescopic rod is extended and retracted, and the clamps 13 are prevented from rotating with the rotation of the threaded rod 12 under the action of the telescopic rod.
[0029] A slide rod is fixedly connected to the inside of the slide groove, and the slide plate 6 is movably mounted on the outer surface of the slide rod. In this embodiment, when the connecting plate 7 moves, it drives the slide plate 6 to slide stably on the outer surface of the slide rod to prevent the slide plate 6 from detaching from the inside of the slide groove.
[0030] One end of the limit block 8 close to the fixed ring 4 is in an inclined state, and the two upper limit blocks 8 and the two lower limit blocks 8 are all symmetrically arranged in the shape of right-angled triangles. The two limit blocks 8 can form an equilateral triangle. In this embodiment, the two limit blocks 8 are in an inclined state. When the limit block 8 contacts the arc-shaped hole 5 of the fixed ring 4, the fixed ring 4 can squeeze the limit block 8 to compress the spring 9.
[0031] The clamping plate 13 is an arc-shaped plate, and both the clamping plate 13 and the raised ribs 15 are made of insulating materials. In this embodiment, the arc-shaped clamping plate 13 facilitates the clamping plate 13 to squeeze the wire spring 11 so that the wire spring 11 is tightly attached to the pin 10, and the clamping plate 13 and the raised ribs 15 are prevented from conducting electricity through the insulating material.
[0032] The length of the connecting plate 7 is 2-5 mm longer than the thickness of the fixing ring 4 . In this embodiment, when the rotating ring 3 contacts the fixing ring 4 , the limiting block 8 can contact the end of the fixing ring 4 away from the rotating ring 3 .
[0033] Working principle: When the utility model is in use, the male connector 1 and the female connector 2 are plugged together, so that the pin 10 is inserted into the socket 14 and enters the wire spring 11. When the male connector 1 and the female connector 2 are plugged together, the limit block 8 on the rotating ring 3 corresponds to the arc hole 5 on the surface of the fixed ring 4. When the limit block 8 corresponds to the arc hole 5, the outer surface of the fixed ring 4 squeezes the limit block 8, driving the connecting plate 7 to deform the spring 9. When the rotating ring 3 contacts the fixed ring 4, the limit block 8 passes through the arc hole 5. Under the elastic force of the spring 9, the connecting plate 7 is driven to reset the limit block 8, so that the limit block 8 hooks the other end of the fixed ring 4 away from the rotating ring 3, and the limit block 8 is prevented from The connector 1 and the female connector 2 are separated due to external force, which increases the stability of the connection between the male connector 1 and the female connector 2. When the male connector 1 and the female connector 2 need to be disassembled, the rotating ring 3 is rotated, and the rotating ring 3 drives the limit block 8 to rotate to the position of the rectangular hole 17, and the limit of the fixing ring 4 is released. The male connector 1 and the female connector 2 can be directly disassembled from the rectangular groove 16. After the pin 10 is inserted into the wire spring 11, the threaded rod 12 is rotated, and the threaded rod 12 drives the clamping plate 13 to move downward. Under the action of the clamping plate 13, the wire spring 11 is close to the surface of the pin 10, so as to avoid the wire spring 11 being unable to return to its original state after multiple removal and insertion of the pin 10, resulting in poor contact of the electrical connector.
