Description

Technical Field

[0001] This invention relates to a plug-in connector, and more particularly to a plug-in connector separation device. Background Technology

[0002] A typical plug-in connector consists of a plug 100 and a socket 200 that are plugged together to form an electrical connection. Traditional plug-socket connections rely entirely on friction for positioning; however, accidental contact or vibration can easily loosen the plug and socket, causing the circuit to break. To maintain a stable connection, a new method exists where the plug and socket are fixed together using a connector. This method involves a nut on the socket sidewall and a countersunk socket on the plug sidewall, secured by a screw 110 inserted into the connector socket and the nut 210. This increases the stability of the plug and socket during operation. However, this method requires tools such as screwdrivers to loosen or tighten the screw 110 when plugging or unplugging the plug 100 and socket 200, which is inconvenient, reduces installation and disassembly efficiency, and increases costs. Summary of the Invention

[0003] To overcome the above-mentioned defects, the present invention provides a plug connector separation device, which can ensure that the plug and socket maintain a stable connection during the plugging process, facilitate quick separation of the plug and socket, and is easy to use without the need for tools.

[0004] The technical solution adopted by the present invention to solve its technical problem is as follows: a connector separation device, comprising a first connector and a second connector, which can be electrically connected by plugging in. A first latch is provided on the side wall of the first connector, and a second latch is provided on the side wall of the second connector. The first latch and the second latch can be engaged simultaneously when the first connector and the second connector are plugged in. A separation device is also provided, comprising a release lever and an elastic reset member. When the first connector and the second connector are plugged in, the sliding direction of the first connector is forward. When the first connector and the second connector are separated, the sliding direction of the first connector is backward. The release lever is mounted on the side wall of the first connector and can slide a set distance in the forward and backward direction. When the release lever slides to a designated position, it can trigger the second latch to disengage from the first latch. The elastic reset member provides an elastic reset force to the release lever to slide backward and disengage from the trigger position of the second latch.

[0005] As a further improvement of the present invention, a limiting wall protrudes on the side wall of the first plug-in, and an elongated guide groove extending in the front-back direction is formed on the limiting wall. The separation device also includes a guide connecting wall. One end of the guide connecting wall is fixedly connected to the tripping lever, and the other end of the guide connecting wall is connected to the elastic reset member. The direction perpendicular to the front-back direction and parallel to the side wall of the first plug-in is defined as the left-right direction. A guide post extending in the left-right direction is fixedly provided on the side wall of the guide connecting wall. The guide post on the guide connecting wall can be slidably inserted into the elongated guide groove on the limiting wall.

[0006] As a further improvement of the present invention, the direction perpendicular to both the front-back and left-right directions is defined as the up-down direction. The elongated guide groove on the limiting wall is an inclined groove extending from the rear upper to the front lower. The elastic reset component of the separation device is an integrally formed spring sheet on the guide connecting wall. The elastic deformation end of the spring sheet is in close contact with the side wall of the first plug-in component, and the spring sheet can generate elastic deformation in the up-down direction when subjected to force.

[0007] As a further improvement of the present invention, the two guide connecting walls are arranged in parallel and spaced apart, and a pressing connecting wall is fixed between the two guide connecting walls. The pressing connecting wall and the two guide connecting walls together form a U-shaped structure. The release lever is fixedly located at the front end of the pressing connecting wall. The spring is an arc-shaped elastic cantilever structure located at the rear end of the pressing connecting wall, or an arc-shaped spring structure located directly below the two guide connecting walls, or a first elastic cantilever structure located in front of and below the guide connecting wall with a set angle thereto. The limiting walls on the side wall of the first plug are two parallel and spaced apart. The U-shaped structure formed by the pressing connecting wall and the guide connecting wall is sleeved on the outside of the two limiting walls, and the spring is inserted between the two limiting walls.

[0008] As a further improvement of the present invention, the limiting wall is also provided with a limiting opening groove structure, the rear end of the pressing connecting wall can be inserted into the limiting opening groove structure on the limiting wall, and the rear end of the pressing connecting wall stops on the bottom surface of the limiting opening groove structure.

[0009] As a further improvement of the present invention, the pressing connecting wall is an arc-shaped structure in which the distance between the middle and the side wall of the first plug is greater than the distance between the two ends and the first plug, and a convex arc-shaped structure is formed on the limiting wall at the position directly opposite to the pressing connecting wall.

[0010] As a further improvement of the present invention, the limiting wall on the first plug-in is also provided with a limiting groove with the opening direction facing the direction of the second plug-in, and the end of the release lever of the separation device facing away from the direction of the second plug-in is also provided with a limiting rib, which can be slidably inserted into the limiting groove.

[0011] As a further improvement of the present invention, the end of the limiting rib is formed with a pointed structure that gradually decreases in size, and an arc-shaped convex structure is formed on the side wall of the limiting rib facing the side wall of the first connector.

[0012] As a further improvement of the present invention, the first buckle is a barbed hook structure on the side wall of the first connector, and the second buckle includes a second elastic cantilever structure on the side wall of the second connector and a hook hole on the elastic cantilever structure. The elastic cantilever structure can elastically cover the outside of the side wall of the first connector, and the barbed hook structure on the side wall of the first connector can be engaged in the hook hole on the second elastic cantilever structure.

[0013] As a further improvement of the present invention, the end of the second elastic cantilever structure on the side wall of the second connector is provided with a guide edge extending obliquely away from the side wall of the first connector. The end of the tripping lever forms a triangular upturned head structure with gradually decreasing thickness. The surface of the triangular upturned head structure facing the side wall of the first connector is a flat structure that is flat against the surface of the side wall of the first plug. The triangular upturned head structure can be accommodated in the triangular gap between the guide edge of the end of the second elastic cantilever structure on the side wall of the second connector and the side wall of the second connector.

[0014] The beneficial effects of this invention are as follows: By setting a first latch and a second latch on the first and second plug-in components of the plug-in connector respectively, when the two are plugged in, the first latch and the second latch automatically engage and connect together, preventing the plug and socket from becoming loose when subjected to vibration or external impact, and preventing poor contact or even open circuit in the circuit. When the plug is pulled out of the socket, it is only necessary to slide the release arm of the separation device to release the second latch from the first latch. After releasing the release arm, the release arm automatically resets under the action of the elastic reset component, making it easy for the first and second plug-in components to be plugged in and connected again. This invention realizes the quick and smooth plugging and unplugging of the first and second plug-in components in the plug-in connector, ensuring the stability of the plug-in connector while facilitating plugging and unplugging. The plugging and unplugging process is convenient and fast, avoiding the need for any tools. Attached Figure Description

[0032] Example: A connector separation device 300 includes a first connector 400 and a second connector 500, which are electrically connected. The first connector 400 has a first latch on its side wall, and the second connector 500 has a second latch on its side wall. The first latch and the second latch are engaged simultaneously when the first connector 400 and the second connector 500 are inserted. A separation device 300 is also provided, which includes a release lever 31. 0 and elastic reset component, assuming that when the first plug 400 is plugged into the second plug, the sliding direction of the first plug is forward, and when the first plug and the second plug are separated, the sliding direction of the first plug is backward, the tripping lever 310 is installed on the side wall of the first plug 400 and can slide a set distance in the front-back direction, and the tripping lever 310 can slide to a designated position to push the second buckle to disengage it from the first buckle, and the elastic reset component provides the tripping lever 310 with an elastic reset force to slide backward to disengage it from the second buckle push position.

[0033] Both the plug and socket include an insulating body and metal parts within the insulating body. When the plug and socket are inserted into each other, the corresponding metal parts also make point contact, thus forming an electrical connection. After the plug and socket are inserted, the first latch of the socket engages with the second latch of the plug, making the plug and socket inseparable. After operating the separation device 300, the separation device 300 disengages the first latch from the second latch, allowing the plug to be pulled out of the socket. By setting the first and second latches on the plug and socket, a stable insertion state can be maintained when the plug and socket are inserted, preventing external forces from causing the metal parts on the plug and socket to detach, resulting in a circuit break and avoiding poor contact. When it is necessary to unplug the plug from the socket, simply operate the separation device 300 to disengage the first latch from the second latch, allowing the plug to be easily unplugged. The operation is convenient. The engaging connection structure on the plug and socket can be one or more sets, and the corresponding separation device 300 can be one or more, depending on the actual situation.

[0034] The first connector 400 has a protruding limiting wall 440 on its side wall. The limiting wall 440 has an elongated guide groove 410 extending in the front-back direction. The separation device 300 also includes a guide connecting wall 350. One end of the guide connecting wall 350 is fixedly connected to the tripping lever 310, and the other end of the guide connecting wall 350 is connected to the elastic reset member. The direction perpendicular to the front-back direction and parallel to the side wall of the first connector 400 is defined as the left-right direction. A guide post 330 extending in the left-right direction is fixedly provided on the side wall of the guide connecting wall 350. The guide post 330 on the guide connecting wall 350 can be slidably inserted into the elongated guide groove 410 on the limiting wall 440. When the release lever 310 of the separation device 300 slides back and forth, the guide post 330 on the guide connecting wall 350 slides along the elongated guide groove 410 on the limiting wall 440 on the side wall of the first plug-in 400. While achieving guidance, it limits the sliding distance of the release lever 310 to prevent it from sliding too far and damaging the second snap-fit ​​structure on the second plug-in 500. At the same time, it also prevents the separation device 300 from disengaging from the first plug-in 400, thus playing a positioning role for the separation device 300.

[0035] Let the direction perpendicular to both the front-back and left-right directions be the up-down direction. The elongated guide groove 410 on the limiting wall 440 is an inclined groove extending from the rear upper part to the front lower part. The elastic reset component of the separating device 300 is a spring piece integrally formed on the guide connecting wall 350. The elastic deformation end of the spring piece is in close contact with the side wall of the first plug-in 400, and the spring piece can produce elastic deformation in the up-down direction when subjected to force. By setting the elongated guide groove 410 on the limiting wall 440 as an inclined structure, pressing the separating device 300 causes the spring piece on it to elastically deform in the up-down direction, thereby causing the release lever 310 on the separating device 300 to slide forward to activate the second buckle. After stopping the pressing, the spring piece automatically resets, thus automatically resetting the separating device 300. The structure is simple and the operation is convenient. In addition, the elastic reset component can also be a spring or spring piece that elastically deforms in the front-back direction.

[0036] Two guide connecting walls 350 are arranged in parallel and spaced apart. A pressing connecting wall 380 is also fixed between the two guide connecting walls 350. The pressing connecting wall 380 and the two guide connecting walls 350 together form a U-shaped structure. The release lever 310 is fixed at the front end of the pressing connecting wall 380. The spring is an arc-shaped elastic cantilever structure 320 located at the rear end of the pressing connecting wall 380, or an arc-shaped spring structure 360 ​​located directly below the two guide connecting walls 350, or a first elastic cantilever structure 370 located in front of and below the guide connecting wall 350 with a set angle thereto. The limiting walls 440 on the side wall of the first plug-in 400 are two arranged in parallel and spaced apart. The U-shaped structure formed by the pressing connecting wall 380 and the guide connecting wall 350 is sleeved on the outside of the two limiting walls 440, and the spring is inserted between the two limiting walls 440.

[0037] The pressing connecting wall 380 and the two guide connecting walls 350 are integrally formed into a U-shaped structure, which is then fitted onto the outside of the two limiting walls 440. This allows the separating device 300 to slide, with the limiting walls 440 and the U-shaped structure again providing front-to-back guidance and upper-lower limiting. Simultaneously, the pressing connecting wall 380 has a pressing operation section on its surface, ideally with a textured surface to facilitate pressing and prevent slippage. When the pressing connecting wall 380 is pressed, the spring sheet deforms, causing the separating device 300 to slide. When the spring sheet is an arc-shaped elastic cantilever structure 320 located at the rear end of the pressing connecting wall 380, the end of the arc-shaped elastic cantilever structure away from the pressing connecting wall 380 forms the free end of the cantilever structure. The free end of the spring sheet structure abuts tightly against the side wall surface of the first connector 400 via a convex arc surface. Pressing down the connecting wall 380 will cause the arc-shaped elastic cantilever structure 320 to undergo elastic deformation in the vertical and horizontal directions. When the spring piece is an arc-shaped spring piece structure 360 ​​located directly below the two guide connecting walls 350, the two ends of the arc-shaped spring piece are connected to the guide connecting wall 350, and its convex arc surface contacts the side wall of the first plug-in 400. Pressing down the connecting wall 380 will cause the arc-shaped spring piece to undergo elastic deformation in the vertical and horizontal directions. When the spring piece is an elastic cantilever structure 370 located in front of and below the guide connecting wall 350 with a set angle thereto, the elastic cantilever structure 370 is flat against the side wall of the first plug-in 400, and the guide connecting wall 350 is in an inclined extension state. Pressing down the connecting wall 380 will cause the first elastic cantilever structure 370 to deform with its root as the fulcrum, thereby causing the guide connecting wall 350 to move downward.

[0038] The limiting wall 440 is also provided with a limiting opening slot structure 450. The rear end of the pressing connecting wall 380 can be inserted into the limiting opening slot structure 450 on the limiting wall 440, and the rear end of the pressing connecting wall 380 stops on the bottom surface of the limiting opening slot structure 450. The opening slot on the limiting wall 440 is preferably a V-shaped opening slot with the opening facing upward and forward. When the separating device 300 is pressed and slids, the rear end of its pressing connecting wall 380 is inserted into the limiting opening slot structure 450 of the limiting wall 440, and is limited and guided by the limiting opening slot structure 450.

[0039] The pressing connecting wall 380 is an arc-shaped structure with a greater distance between its middle and the side wall of the first insert 400 than the distance between its two ends and the first insert 400. A convex arc-shaped structure is formed on the limiting wall 440 directly opposite the pressing connecting wall 380. This structure is aesthetically pleasing. The pressing connecting wall 380 and the limiting wall 440 make contact through an arc surface, preventing jamming. Furthermore, a hollow structure can be provided in the middle of the pressing connecting wall 380, directly opposite the highest point of the limiting wall 440. This allows the pressing connecting wall 380 to avoid contact with the highest point of the limiting wall 440 after being pressed down, effectively reducing the vertical dimensions of the separating device 300.

[0040] The limiting wall 440 on the first connector 400 is also provided with a limiting groove 420 with its opening facing the second connector 500. The release lever 310 of the separating device 300 has a limiting rib 340 on its end facing away from the second connector 500. The limiting rib 340 can be slidably inserted into the limiting groove 420. When the separating device 300 slides back and forth on the first connector 400, the limiting rib 340 and the limiting groove 420 cooperate to guide and limit the movement, while also reinforcing the connection between the separating device 300 and the first connector 400.

[0041] The limiting rib 340 has a pointed end with a gradually decreasing size, and an arc-shaped convex structure is formed on the side wall of the limiting rib 340 facing the side wall of the first connector 400. This structure ensures that the limiting rib 340 can be quickly and accurately inserted into the limiting groove 420, avoiding interference with the upper side wall of the limiting groove 420, while ensuring that the limiting rib 340 is in close contact with the side wall of the limiting groove 420 to prevent up-and-down wobbling.

[0042] The first buckle is a barbed hook structure 430 on the side wall of the first connector 400. The second buckle includes a second elastic cantilever structure 520 on the side wall of the second connector 500 and a hook hole 510 on the second elastic cantilever structure 520. The second elastic cantilever structure 520 can elastically cover the outside of the side wall of the first connector 400. The barbed hook structure 430 on the side wall of the first connector 400 can be engaged in the hook hole 510 on the second elastic cantilever structure 520. The hook hole 510 can be hung on the barbed hook structure 430 to prevent the first connector 400 and the second connector 500 from separating, thereby achieving a fastening connection between the two. In addition to the method of fastening the first buckle and the second buckle by using the barbed hook structure 430 and the hook hole 510, they can also be fastened by using magnetic elements to magnetically attract the two when they are close together, or by using a groove and an elastic pin to insert, etc.

[0043] The second elastic cantilever structure 520 on the side wall of the second connector 500 has a guide edge 530 that extends obliquely away from the side wall of the first connector 400. The end of the tripping lever 310 forms a triangular upturned structure with gradually decreasing thickness. The surface of the triangular upturned structure facing the side wall of the first connector 400 is a flat structure that is flat against the surface of the side wall of the first plug. The triangular upturned structure can be accommodated in the triangular gap between the guide edge 530 at the end of the second elastic cantilever structure 520 on the side wall of the second connector 500 and the side wall of the second connector 500.

[0044] When the first connector 400 and the second connector 500 are normally connected, the triangular upturned structure at the end of the release lever 310 is just positioned within the triangular gap between the guide upturned edge 530 at the end of the elastic cantilever structure 370 on the side wall of the second connector 500 and the side wall of the second connector 500. When the release lever 310 is slid forward, the triangular upturned edge slides forward and gradually pushes up the second elastic cantilever structure 520 on the side wall of the second connector 500, causing the second latch to disengage from the first latch. This structure ensures that when the separation device 300 is operated, the second latch can be smoothly and quickly separated from the first latch, and the separation will not fail due to errors in the sliding direction of the release lever 310.
