A connector with push-pull self-locking function

Abstract

The present invention discloses a connector with a push-pull self-locking function, which relates to the technical field of connectors, and includes a female seat and a male head, wherein the end of the female seat is rotatably connected to a first limiting ring, and one end of the female seat away from the first limiting ring is fixedly connected to a first fixing ring, and the first fixing ring is slidably connected to a first sliding ring, and a guide groove is provided on the inner wall of the first sliding ring. The present invention achieves a plug-and-lock effect of the connector through corresponding locking buckle extrusion fit, optimizes the docking locking process, and eliminates complicated locking steps. Moreover, since the locking buckles at both ends are rigidly buckled, when the wires at either end of the left or right ends of the connector are subjected to external pulling force, unless the locking buckles at both ends are broken, the locking buckles at both ends will not be unlocked due to the displacement caused by the pulling force, thereby avoiding the easy disconnection of the two ends of the connector due to the external pulling force on the wires, and has a strong tensile strength.

Description

Technical Field

[0001] The present invention relates to the technical field of connectors, and in particular to a connector with a push-pull self-locking function. Background Art

[0002] In modern industry, communications, medical equipment, and consumer electronics, connectors are widely used to achieve reliable electrical or signal connections, especially in situations where frequent plugging and unplugging or use in a vibrating environment are required.

[0003] The common connectors on the market currently mainly include the following two types: 1. Quick-connect connector: Spring-loaded pins or clamps are used to achieve quick connection and disconnection without the assistance of tools. However, its locking mechanism is relatively simple, with limited tensile strength, and it is easy to accidentally unlock when subjected to external pulling force; 2. Screw-in connector: After insertion, rotate a certain angle to align and lock the male head with the buckle on the female socket, and rotate in the opposite direction to unlock. Although it provides a better locking effect, the operation is relatively complicated and is not suitable for application scenarios with frequent plugging and unplugging. Therefore, in order to take into account both tensile strength and ease of operation, the present invention provides a connector with a push-pull self-locking function. Summary of the invention

[0004] In order to overcome the disadvantage of not being able to take both tensile strength and ease of operation into consideration, the present invention provides a connector with a push-pull self-locking function.

[0005] A connector with a push-pull self-locking function comprises a female seat and a male head, the end of the female seat is rotatably connected with a first limiting ring, the end of the female seat away from the first limiting ring is fixedly connected to a first fixing ring, the first fixing ring is slidably connected to the first sliding ring, the inner wall of the first sliding ring is provided with a guide groove, the first limiting ring is slidably connected to the guide groove, an elastic telescopic rod symmetrically distributed along the female seat is fixedly connected between the first sliding ring and the first fixing ring, the end of the male head is fixedly connected to a second limiting ring, the first limiting ring and the second limiting ring are both fixedly connected with at least one corresponding locking buckle, the locking buckle in the first limiting ring and the corresponding locking buckle in the second limiting ring are both arranged as wedge-shaped surfaces, the corresponding locking buckles are extruded and matched through the wedge-shaped surfaces, and when the male head is docked with the female seat, the first sliding ring and the second limiting ring are closed to each other.

[0006] As a preferred technical solution of the present invention, the diameter of the first limiting ring is smaller than the diameter of the second limiting ring, and the diameter of the first sliding ring is equal to the diameter of the second limiting ring.

[0007] As a preferred technical solution of the present invention, it also includes a second fixing ring, which is fixed to the end of the male head away from the second limiting ring, a second sliding ring is slidably connected inside the second fixing ring, the second sliding ring is slidably connected to the male head, the first limiting ring and the second sliding ring are both fixed with at least one corresponding limiting buckle, and a first spring is fixed between the second sliding ring and the male head.

[0008] As a preferred technical solution of the present invention, the end faces opposite to the limiting buckles in the first limiting ring and the corresponding limiting buckles on the second sliding ring are both set as wedge-shaped surfaces, and the corresponding limiting buckles are squeezed and fitted through the wedge-shaped surfaces.

[0009] As a preferred technical solution of the present invention, it also includes a third fixing ring, which is fixed to the side of the mother seat close to the first sliding ring, and the third fixing ring is slidably connected with circumferentially evenly distributed limiting columns, a second spring is fixed between the limiting columns and the third fixing ring, and the side of the first sliding ring close to the limiting columns is provided with circumferentially evenly distributed limiting grooves, and the limiting grooves correspond one-to-one to the limiting columns.

[0010] As a preferred technical solution of the present invention, it also includes a fixed tube, which is fixedly connected to the first fixed ring, and the fixed tube is rotatably connected to a rotating plate, and the first fixed ring and the first sliding ring are both in contact with the rotating plate.

[0011] As a preferred technical solution of the present invention, it also includes relatively distributed fixing plates, the relatively distributed fixing plates are respectively fixedly connected to the first sliding ring and the second limiting ring, and the fixing plates are fixedly connected to prompt plates.

[0012] As a preferred technical solution of the present invention, a reflective film is attached to the surface of the prompting plate.

[0013] The beneficial effects of the present invention are as follows: the present invention achieves a plug-and-lock effect for the connector through extrusion and fit of the corresponding locking buckles, optimizes the docking and locking process, eliminates complicated locking steps, and because the locking buckles at both ends are rigidly fastened, when the wires at either end of the left or right end of the connector are subjected to external pulling force, unless the locking buckles at both ends are pulled off, the locking buckles at both ends will not be unlocked due to extrusion and displacement due to the pulling force, thereby avoiding the two ends of the connector from being easily disconnected due to external pulling force on the wires, and having strong tensile strength.

[0014] The present invention inserts the first limiting ring into the second limiting ring so that the left end face of the second limiting ring and the right end face of the first sliding ring contact and close with each other, thereby achieving closure around the connector port, having good sealing effect, being waterproof and dustproof, and having stable connection.

[0015] In addition to the rigid fastening by the locking buckles at both ends, the present invention also uses the limiting buckles at both ends to achieve elastic fastening, which not only takes into account the stability of the connector to prevent the two ends of the connector from being easily disconnected by external forces, but also takes into account that in extreme cases, when the locking buckles are pulled off by external forces, the disconnected connector can be automatically reconnected to achieve a double insurance effect.

[0016] During the high-frequency vibration process of the present invention, a part of the limiting column is always stuck in the corresponding limiting groove due to the vibration, thereby achieving the effect of fixing the first sliding ring and preventing the first sliding ring from moving to the left due to high-frequency vibration caused by external force during use, causing the connector to be unlocked and disconnected.

[0017] After the connector is plugged in, the present invention pushes the rotating plate downward so that the rotating plate rotates to a horizontal block between the first sliding ring and the first fixed ring, thereby further reinforcing the first sliding ring to prevent the first sliding ring from being accidentally touched due to external force during use, causing the first sliding ring to move to the left and causing the connector to be unlocked and disconnected.

[0018] The present invention performs alignment through the prompt plates on the left and right sides, so that the locking buckles at both ends and the limiting buckles at both ends can be accurately connected. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0030] Embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0031] Embodiment 1: A connector with push-pull self-locking function, referring to the attached Figure 1 To Attachment Figure 4 , including a female seat 101 and a male head 106, the right end of the female seat 101 is rotatably connected to a first limiting ring 102, the left end of the female seat 101 is fixedly connected to a first fixing ring 104, the first fixing ring 104 is slidably connected to a first sliding ring 103 along the left and right directions, the inner wall of the first sliding ring 103 is provided with a guide groove 1031, the first limiting ring 102 is slidably connected to the guide groove 1031, and an elastic telescopic rod 105 symmetrically distributed along the upper and lower sides of the female seat 101 is fixedly connected between the first sliding ring 103 and the first fixing ring 104, the left end of the male head 106 is fixedly connected to a second limiting ring 107, the diameter of the first limiting ring 102 is smaller than the diameter of the second limiting ring 107, so that the first limiting ring 102 can be inserted into the second limiting ring 107 , and the diameter of the first sliding ring 103 is equal to the diameter of the second limiting ring 107, two corresponding locking buckles 1032 are fixedly connected in the first limiting ring 102 and the second limiting ring 107, and a gap for the first limiting ring 102 to pass through is arranged between the second limiting ring 107 and the locking buckle 1032 thereon, and the end faces opposite to the locking buckle 1032 in the first limiting ring 102 and the corresponding locking buckle 1032 in the second limiting ring 107 are both arranged as wedge-shaped surfaces, and the corresponding locking buckles 1032 are squeezed and matched through the wedge-shaped surfaces. When the male head 106 is docked with the female seat 101, the first sliding ring 103 and the second limiting ring 107 are closed to each other, so that the connection port of the connector can be sealed by the first sliding ring 103 and the second limiting ring 107.

[0032] If the connector needs to be connected, first insert the male connector 106 to the left into the female connector 101. During the insertion process, the second limiting ring 107 moves to the left synchronously with the male connector 106, and the locking buckle 1032 on the second limiting ring 107 moves to the left synchronously, so that the first limiting ring 102 is inserted between the second limiting ring 107 and the gap between the right locking buckle 1032. When the wedge-shaped surface of each locking buckle 1032 on the right side contacts the wedge-shaped surface of the corresponding locking buckle 1032 on the left side, the locking buckle 1032 on the right side squeezes the corresponding locking buckle 1032 on the left side through the wedge-shaped surface, so that the first limiting ring 102 rotates. When the first limiting ring 102 rotates, it pushes the first sliding ring 103 to the left through the guide groove 1031, so that the first limiting ring 102 A sliding ring 103 slides to the left into the first fixed ring 104, and the elastic telescopic rod 105 is compressed. When the wedge surface of the left locking buckle 1032 rotates to disengage from the wedge surface of the corresponding locking buckle 1032 on the right, the male head 106 is completely inserted into the female seat 101. At this time, the elastic telescopic rod 105 resets and drives the first sliding ring 103 to slide to the right. The first sliding ring 103 pushes the first limiting ring 102 to rotate in the opposite direction through the guide groove 1031, so that the locking buckle 1032 on the left rotates in the opposite direction to buckle the locking buckle 1032 on the right. In this way, the plug-and-lock effect of the connector is achieved. At the same time, the left end face of the second limiting ring 107 and the right end face of the first sliding ring 103 contact and close each other.

[0033] Afterwards, if the connector needs to be disconnected, the first sliding ring 103 is pushed to the left first, the elastic telescopic rod 105 is compressed again, and the first sliding ring 103 pushes the first limiting ring 102 to rotate again through the guide groove 1031, so that the locking buckle 1032 on the left side rotates until it no longer locks the locking buckle 1032 on the right side, and then the male head 106 is pulled out to the right. During the pulling out process, the second limiting ring 107 moves to the right synchronously with the male head 106, and the locking buckle 1032 on the right side moves to the right synchronously with the second limiting ring 107. After it is completely pulled out, the first sliding ring 103 is released, and the elastic telescopic rod 105 is reset to drive the first sliding ring 103 to slide to the right, and the first sliding ring 103 pushes the first limiting ring 102 to rotate in the opposite direction and reset through the guide groove 1031.

[0034] In summary, first, the present invention achieves a plug-and-lock effect of the connector through the corresponding locking buckles 1032 extrusion fit, optimizes the docking and locking process, eliminates complicated locking steps, and because the locking buckles 1032 at both ends are fixed and rigidly fastened, when the wires at either end of the left or right end of the connector are subjected to external pulling force, unless the locking buckles 1032 at both ends are pulled off, the locking buckles 1032 at both ends will not be unlocked due to the extrusion and displacement caused by the pulling force, thereby avoiding the two ends of the connector from being easily disconnected due to the external pulling force on the wires, and having strong tensile strength.

[0035] Second, the present invention inserts the first limiting ring 102 into the second limiting ring 107, so that the left end face of the second limiting ring 107 and the right end face of the first sliding ring 103 contact and close with each other, thereby achieving closure around the connector port, with good sealing effect, waterproof and dustproof, and stable connection.

[0036] Embodiment 2: Based on Embodiment 1, Figure 5 and attached Figure 6 , also includes a second fixing ring 201, the second fixing ring 201 is fixedly connected to the right end of the male head 106, a second sliding ring 2011 is slidably connected inside the second fixing ring 201 along the left and right directions, the second sliding ring 2011 is slidably connected to the male head 106, the first limiting ring 102 and the second sliding ring 2011 are both fixedly connected to two corresponding limiting buckles 202, the limiting buckles 202 in the first limiting ring 102 and the corresponding limiting buckles 202 on the second sliding ring 2011 are both set as wedge-shaped surfaces, the corresponding limiting buckles 202 are squeezed and matched through the wedge-shaped surfaces, and a first spring 203 is fixedly connected between the second sliding ring 2011 and the male head 106.

[0037] When the male connector 106 is inserted to the left into the female connector 101, the limiting buckle 202 on the first limiting ring 102 will interlock with the limiting buckle 202 on the second sliding ring 2011, just like the locking buckle 1032, to achieve a double locking effect. In addition, when the connector is in use, if the wires at either end of the left or right ends are pulled by external forces, and the locking buckles 1032 at both ends are hard pulled off, thereby causing the two ends of the connector to be disconnected, then during the process of being pulled by external forces, the limiting buckle 202 on the first limiting ring 102 will pull the limiting buckle 202 on the second sliding ring 2011 to the left relative to the male connector 106. The first spring 203 is compressed, and when the locking buckles 1032 at both ends are broken, the first spring 203 is reset, driving the second sliding ring 2011 to slide to the right relative to the male head 106 and the second fixing ring 201. The limiting buckle 202 on the second sliding ring 2011 will pull the limiting buckle 202 on the first limiting ring 102 to move to the right relative to the female seat 101, thereby pulling the first limiting ring 102 to move to the right and reset, thereby driving the female seat 101 to move to the right until the male head 106 is reinserted into the female seat 101.

[0038] In summary, in addition to the rigid fastening through the locking buckles 1032 at both ends, the present invention also performs elastic fastening through the limiting buckles 202 at both ends, which not only takes into account the stability of the connector to prevent the two ends of the connector from being easily disconnected by external forces, but also takes into account that in extreme cases, when the locking buckle 1032 is pulled off by external forces, the disconnected connector can be automatically reconnected to achieve a double insurance effect.

[0039] Refer to the attached Figure 7 and attached Figure 8 , and also includes a third fixing ring 301, the third fixing ring 301 is fixedly connected to one side of the mother seat 101 close to the first sliding ring 103, the third fixing ring 301 is slidably connected with circumferentially evenly distributed limiting columns 302, a second spring 303 is fixedly connected between the limiting columns 302 and the third fixing ring 301, and a circumferentially evenly distributed limiting groove 304 is opened on one side of the first sliding ring 103 close to the limiting column 302, and the limiting groove 304 corresponds one-to-one to the limiting column 302.

[0040] When the connector is subjected to high-frequency vibration by external force, the high-frequency vibration causes the limiting column 302 to continuously jump, and the second spring 303 deforms adaptively. Since the external force is applied unidirectionally during each vibration, when the limiting column 302 on one side slides toward the side that stretches the second spring 303, the limiting column 302 on the opposite side slides toward the side that compresses the second spring 303. In this way, during the high-frequency vibration process, there is always a part of the limiting column 302 that is stuck in the corresponding limiting groove 304, thereby achieving the effect of fixing the first sliding ring 103, preventing the first sliding ring 103 from moving to the left due to high-frequency vibration caused by external force during use, causing the connector to unlock and disconnect. When the vibration stops, the second spring 303 resets to cause the limiting column 302 to disengage from the limiting groove 304, automatically releasing the fixation of the first sliding ring 103.

[0041] Refer to the attached Fig. 9 , further comprising a fixed tube 401 , the fixed tube 401 is fixedly connected to the first fixed ring 104 , a rotating plate 402 is rotatably connected to the fixed tube 401 , and both the first fixed ring 104 and the first sliding ring 103 are in contact with the rotating plate 402 .

[0042] After plugging the connector, the rotating plate 402 is pushed downward again so that the rotating plate 402 rotates to a horizontal position between the first sliding ring 103 and the first fixed ring 104, thereby further reinforcing the first sliding ring 103 and preventing the first sliding ring 103 from being accidentally touched due to external force during use, causing the first sliding ring 103 to move to the left and the connector being unlocked and disconnected. Before disconnecting the connector, the rotating plate 402 is pushed upward first so that the rotating plate 402 rotates away from between the first sliding ring 103 and the first fixed ring 104, thereby releasing the fixation of the first sliding ring 103.

[0043] Embodiment 3: Based on Embodiment 2, Fig.10 , and also includes a fixed plate 501 relatively distributed on the left and right, the fixed plates 501 relatively distributed on the left and right are respectively fixedly connected to the first sliding ring 103 and the second limiting ring 107, and a prompt plate 502 is fixedly connected to the fixed plate 501, and a reflective film is attached to the surface of the prompt plate 502.

[0044] When the locking buckles 1032 at both ends and the limiting buckles 202 at both ends are connected to each other, they can be aligned through the prompt plates 502 on the left and right sides. In this way, even in poor light conditions, the locking buckles 1032 at both ends and the limiting buckles 202 at both ends can be easily and accurately connected.

[0045] The embodiments of the present invention are described in detail above with reference to the accompanying drawings, but the present invention is not limited to the above embodiments, and various changes can be made within the knowledge scope of those skilled in the art without departing from the spirit of the present invention.
