Description

Technical Field

[0001] The utility model relates to the technical field of electric connectors, in particular to an electric connector with a clamping assembly. Background Art

[0002] An electrical connector consists of a fixed-end electrical connector, i.e., a female contact (referred to as a socket), and a free-end electrical connector, i.e., a male contact (referred to as a plug). Electrical connectors are categorized by shape into circular and rectangular connectors, and by connection methods, into threaded, bayonet (quick) connections, latching, push-pull, and plug-in connections. During installation, a threaded circular electrical connector secures the plug and socket by threading the internal threaded barrel on the plug onto the external threaded barrel on the socket. However, this method of securing the plug and socket is relatively simple, and a single threaded connection may loosen after the plug and socket have been fixed for a long time, potentially causing the plug and socket to detach.

[0003] Chinese patent CN218940192U discloses an electrical connector with a tail clamping structure, comprising a socket, a plug support column and a plug body fixedly installed on the left side of the plug support column, wherein the socket and the outer side of the plug body are provided with a screw connection component, a socket is provided inside the socket, a joint is fixedly installed on the right side of the socket, a limiting groove is provided on the side of the plug body, and a fixing component is provided on the outer side of the plug support column. The utility model relates to the technical field of electrical connectors; the electrical connector with a tail clamping structure, through the sliding ring with the insertion rod passing through the interior of the fixing ring, and then inserted into the interior of the socket, after pressing the button, the fixing rod can be inserted into the interior of the fixing groove by the moving rod and the connecting rod, thereby completing the fixation of the insertion rod, and the fixed insertion rod can better limit the internal threaded barrel through the fixing ring, thereby achieving a better fixing effect on the device.

[0004] When fixing the plug and the socket of the electrical connector to each other, it is first necessary to rotate the external threaded barrel, and then manually push the sliding ring to drive the insertion rod to be inserted into the socket of the socket through the sliding ring, and then manually press the button to insert the fixing rod into the fixing groove in the socket. This requires multiple manual back and forth operations, which makes the operation very cumbersome. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to further understand the features, technical means, specific objectives and functions achieved by the present invention, the present invention is described in further detail below in conjunction with the accompanying drawings and specific implementation methods.

[0022] Reference Figures 1 to 5 As shown, an electrical connector with a clamping assembly includes a socket 1 and a plug 2, a nut 3 is movably sleeved on the plug 2, a locking mechanism 4 is provided on the side of the nut 3 close to the socket 1, and a slot 11 is provided on the socket 1 to be plugged into and cooperate with the locking mechanism 4.

[0023] When the electrical connector needs to be used, first hold the plug 2 by hand, and then insert the plug 2 into the socket 1. After the plug 2 is inserted into the socket 1, the nut 3 will abut against the socket 1, and the locking mechanism 4 will be inserted into the slot 11. Then, the nut 3 is rotated to tighten the nut 3 on the socket 1, and the plug 2 is fixed to the socket 1 through the nut 3. In this way, when the nut 3 is tightened, the locking mechanism 4 will also be automatically fixed in the slot 11. After the nut 3 is fixed, the locking mechanism 4 can be automatically fixed in the slot 11, thereby forming a locking effect between the plug 2 and the socket 1 again. In this way, only the nut 3 needs to be operated separately, so the operation method is simpler and faster.

[0024] Reference Figure 2 and Figure 3 As shown, the locking mechanism 4 includes a housing 41 , a ball 42 that can extend outward from the housing 41 is provided on the housing 41 , and a moving groove 12 for the ball 42 to move is provided in the slot 11 .

[0025] When the nut 3 is tightened, it will synchronously drive the shell 41 to move in the slot 11, and the shell 41 will also synchronously drive the ball 42 to move in the moving groove 12, and then the ball 42 will be engaged with the moving groove 12 by means of the locking mechanism, thereby fixing the shell 41 in the slot 11, thereby forming a re-locking effect between the plug 2 and the socket 1.

[0026] Reference Figure 2 and Figure 3 As shown, the slot 11 is ring-shaped, and the housing 41 can be inserted into the slot 11 , and the housing 41 can be arranged in the slot 11 so as to be movable along the slot 11 .

[0027] Because the nut 3 is rotated when being tightened, and the nut 3 is ring-shaped when rotating, the housing 41 can move better in the slot 11, thereby achieving a better locking effect between the plug 2 and the socket 1.

[0028] Reference Figure 4 As shown, the edge of the movable groove 12 is provided with an arc edge.

[0029] Because the shape of the ball 42 is arc-shaped, when the ball 42 enters the movable groove 12, the setting of the arc-shaped edge allows the ball 42 to enter the movable groove 12 more smoothly, and when the ball 42 moves away from the movable groove 12, it can automatically return to its original position along the arc-shaped edge without manual operation, and the area where the ball 42 is engaged with the movable groove 12 is larger, which can further improve the locking effect of the plug 2 and the socket 1.

[0030] Reference Figure 3 As shown, the shell 41 is provided with an abutment portion 43 at one end close to the socket 1, which can extend the shell 41 to move horizontally, and the slot 11 is provided with an abutment surface that abuts and cooperates with the abutment portion 43. One end of the abutment portion 43 is provided with an extension mechanism 5 for driving the ball 42 to extend out or be retracted into the shell 41.

[0031] When the nut 3 is tightened, the abutment portion 43 on the shell 41 will abut against the abutment surface in the slot 11. Through the mutual cooperation between the abutment portion 43 and the abutment surface in the slot 11, and through the extension mechanism 5 on the abutment portion 43, the ball 42 will automatically extend toward the outside of the shell 41, and the ball 42 will be engaged with the movable groove 12.

[0032] Reference Figure 5 As shown, the extension mechanism 5 includes a connecting block 51, a limiting shaft 53, a spring 54 and a second abutting block 56; the connecting block 51 is arranged on the abutting portion 43, and a first abutting block 55 is provided on the connecting block 51, and a fixing ring 52 is also provided on the connecting block 51; the limiting shaft 53 is arranged on the side of the fixing ring 52 away from the connecting block 51; the spring 54 is sleeved on the limiting shaft 53, and one end of the spring 54 is abutted against the nut 3, and the other end is abutted against the fixing ring 52; the second abutting block 56 is movably arranged in the shell 41 by a tension spring 57, and one end of the second abutting block 56 is abutted against the first abutting block 55, and the other end is connected to the ball 42.

[0033] When the abutment portion 43 abuts against the abutment surface, it drives the connecting block 51 to move toward the inside of the shell 41, thereby synchronously driving the first abutment block 55 and the fixing ring 52 to move toward the inside of the shell 41, so that the fixing ring 52 will squeeze the spring 54, causing the spring 54 to be compressed and deformed with elastic restoring force, and the spring 54 is limited by the limiting shaft 53, and when the abutment block moves toward the inside of the shell 41, the second abutment block 56 will automatically disengage from the first abutment block 55, thereby driving the second abutment block 56 to extend toward the outside of the shell 41 through the tension spring 57, thereby synchronously driving the ball 42 to extend. The shell 41 is clamped with the movable groove 12. When the nut 3 is loosened, the abutment portion 43 will move away from the abutment surface, so that the first abutment block 55 will be automatically reset by the spring 54. At the same time, when the ball 42 is disengaged from the movable groove 12, it will also automatically retract into the inside of the shell 41, thereby driving the second abutment block 56 to also synchronously retract into the inside of the shell 41. In this way, since the strokes of the first abutment block 55 and the second abutment block 56 are the same, when the nut 3 completes its distance from the socket 1, the first abutment block 55 will automatically abut against the second abutment block 56, and the second abutment block 56 can be fixed in the shell 41 through the first abutment block 55.

[0034] Reference Figure 5As shown, the first abutting block 55 is provided with a first inclined surface 551 , and the second abutting block 56 is provided with a second inclined surface 561 engaged with the first inclined surface 551 .

[0035] Through the cooperation between the first inclined surface 551 and the second inclined surface 561, when the first abutting block 55 moves away from the second abutting block 56, the second inclined surface 561 on the second abutting block 56 will move along the first inclined surface 551 of the first abutting block 55, so that the second abutting block 56 is more stable when extending toward the outside of the shell 41, and when the second abutting block 56 is retracted into the inside of the shell 41, the second abutting block 56 can be completely retracted into the shell 41.

[0036] Reference Figure 1 As shown, a protrusion 31 is provided on the outer wall surface of the nut 3.

[0037] Since the nut 3 needs to be manually operated when it is rotated, the setting of the protrusion 31 can increase the friction when holding the nut 3, thereby saving effort and making it more convenient to operate the nut 3.

[0038] The above embodiments merely represent one or several implementations of the present invention. While the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the present invention. It should be noted that a person skilled in the art would be able to make various modifications and improvements without departing from the spirit of the present invention, and these modifications and improvements fall within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be determined by the appended claims.
