[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Example:

[0022] See also Figure 1 A screw for quickly locking an electrical connector comprises a free end locking assembly and a fixed end locking assembly, the free end locking assembly and the fixed end locking assembly are movably connected; the free end locking assembly and the fixed end locking assembly are used to connect and fix two electrical connectors to the plug ends 10.

[0023] The fixed end locking assembly includes a mounting screw 5, one end of which is provided with a through hole A, and an outer wall of the mounting screw 5 is provided with a slot 501, which is connected to the through hole A.

[0024] The free end locking assembly includes a locking screw 8, one end of which is provided with a through hole B, the extension direction of the through hole B is perpendicular to the axial direction of the locking screw 8, and both ends of the through hole B are provided with pins 9, which can cooperate with the card slot 501. Figure 1 As shown, the mounting screw 5 and the locking screw 8 are respectively connected to a plug-in end 10, and then the pin 9 at the end of the locking screw 8 is inserted into the through hole and the locking screw 8 is rotated so that the pin 9 is engaged with the slot 501 to achieve the connection and fixation of the mounting screw 5 and the locking screw 8.

[0025] In the present application, the locking screw 8 is composed of a first cylinder 801, a second cylinder 802 and a third cylinder 803 connected in sequence, and the pin 9 is installed on the first cylinder 801; and the diameters of the first cylinder 801, the second cylinder 802 and the third cylinder 803 increase in sequence.

[0026] In the present application, the free end locking assembly also includes a spring 7 and a flat washer B6, which are both sleeved on the first cylinder 801, one end of the spring 7 is connected to the end of the second cylinder 802, and the other end of the spring 7 is connected to the flat washer B6. When the two plug-in ends 10 are connected, the spring 7 is pressed against the surface of the plug-in ends 10. After the mounting screw 5 and the locking screw 8 are connected, the spring 7 is compressed, and the restoring force of the spring 7 is used to generate a pulling force on the locking screw 8, so that the pin 9 will not slide out of the slot 501.

[0027] In the present application, the fixed end locking assembly also includes a limit assembly, which is sleeved on one end of the mounting screw 5, and a nut 1 is provided on one side of the limit assembly, and the nut 1 is threadedly matched with the mounting screw 5. When installed, the limit assembly is located between the outer end of the plug end 10 and the nut 1.

[0028] Among them, the limiting assembly includes a sleeve 4, a flat washer A3 is arranged on the side of the sleeve 4 away from the slot 501, a spring washer 2 is arranged on one side of the flat washer A3, the spring washer 2 is located on the inner side of the nut 1, and when installed, the spring washer 2 is close to the nut 1, and the flat washer A3 is located between the sleeve 4 and the spring washer 2.

[0029] In the present application, a boss is provided at one end where the mounting screw 5 and the locking screw 8 are connected, and a slot 501 is provided through the boss, and both sides of the boss are milled flat to form a flat surface. The boss is located at one end where the mounting screw 5 and the locking screw 8 are connected, and by making flat countersunk holes on both sides of the flange of the plug-in end 10, the flat countersunk holes cooperate with the milled flat positions on both sides of the boss, so that the mounting screw 5 can be prevented from rotating.

[0030] In the present application, the surface of the third cylinder 803 is configured as a knurled pattern to increase friction. The card slot 501 is composed of a vertical section and an inclined section. Figure 1 As shown in , the upper end of the vertical section is connected to the upper end of the inclined section, the inclined section is tilted downward, and the outer end of the inclined section is lower than the upper end of the vertical section. When the pin 9 slides into the outer end of the inclined section, it will not slide out easily.

[0031] In a possible embodiment, a small section is milled flat on both sides of the place where the upper end of the first cylinder 801 matches with the plug end 10, and flat countersunk holes are also made on both sides of the flange of the plug end 10. When the milled flat part matches with the countersunk hole, the locking screw 8 can be prevented from rotating. When the upper end of the locking screw 8 is inserted into the mounting screw 5 and rotated, the milled flat part of the first cylinder 801 is not in contact with the deformed countersunk hole on the plug end 10. When the locking screw 8 rotates to make the pin 9 enter the slot 501, since the pin 9 is located in the inclined section, the first cylinder 801 will move to the side of the spring 7, so that the milled flat part matches with the flat countersunk hole on the flange.

[0032] Working principle: When the free end locking assembly and the fixed end locking assembly are plugged and locked, push the locking screw 8 to compress the spring 7, so that the pin 9 enters the slot 501 of the mounting screw 5 and is placed horizontally with the slot 501 hole; at this time, rotate the locking screw 8 to make the pin 9 enter the slot 501, and the mounting screw 5 and the locking screw 8 can be locked; rotate the locking screw 8 in the opposite direction again until the pin 9 is in the vertical section with the slot 501, loosen the locking screw 8, the spring 7 stretches, the mounting screw 5 and the locking screw 8 are separated, and the two plug-in ends 10 can be separated. This locking method is fast and convenient, saves time, and has reliable locking, meeting the needs of fast locking. It also prevents rotation, improves locking efficiency, and is convenient and quick when plugging and unplugging frequently; it can also be locked freely when the operating space is narrow.

[0033] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model.
