Abstract
Description
Technical Field
[0001] This utility model relates to connectors, and more particularly to a connector with a locking structure. Background Technology
[0002] In existing technologies, high-voltage connectors typically feature a primary locking mechanism to ensure a secure connection after mating. However, in some applications, relying solely on the primary locking mechanism can lead to springback or loosening due to external forces or prolonged vibration, thus affecting connection reliability. Therefore, some connector structures incorporate an auxiliary secondary locking mechanism. This secondary locking mechanism further secures the primary locking mechanism after it has closed completely, preventing accidental unlocking.
[0003] In known structures, secondary locking mechanisms typically utilize a flexible hook that engages with a rotating handle. When the hook is engaged with the handle, the primary lock is fixed in the closed position, achieving a secondary locking effect. Furthermore, to release the secondary lock, the operator must apply force with their fingers to push the hook to the left, causing the hook to deform upwards and disengage from the rotating handle, thus releasing the secondary lock.
[0004] However, in existing technologies, the latch area experiences stress concentration during handle retraction, which can easily lead to fatigue fracture of the latch over prolonged operation, causing locking failure. Furthermore, the handle pressing position in existing structures is uncomfortable to operate during unlocking. Therefore, the secondary locking mechanism still needs improvement in terms of durability and ease of use. Utility Model Content
[0005] One objective of this invention is to provide a connector with a locking structure, which facilitates the user to apply force and lock, and provides a more reliable locking effect between the first connector and the second connector.
[0006] To achieve the above objectives, this utility model provides a connector with a locking structure, comprising a first connector, a handle assembly, and a second connector. The first connector includes a first body and a pair of first pivots. The handle assembly includes a handle and a latch. The handle includes a pair of rotating arms and a connecting rod connecting the rotating arms. The rotating arms are provided with a first pivot hole and a second pivot hole. The handle is movably engaged with the first body by passing through the first pivot hole of the rotating arm and a first pivot. The latch includes a pressure plate, a pin connecting the pressure plate, and a pin. The second connector includes a second body and a pair of second pivots. The second body is inserted into the first body and is provided with a stop block and a locking hole. The second pivots pass through the second pivot holes of the rotating arms. The connecting rod is provided with a through groove and a limiting plate corresponding to the stop block. The latch moves along the through groove of the limiting plate and engages with the connecting rod. When the handle rotates to the second body and stops at one side of the stop block, the latch is pushed by an external force and moves towards the stop block, causing the pin to extend into the locking hole, thereby locking the first connector with the second connector.
[0007] In one embodiment of the present invention, the first connector includes a protective plate disposed on the first body, and the protective plate is located on one side of the first pivot. The rotating arm has an arc-shaped portion, and when the handle is rotated to the first body, the arc-shaped portion can push against the protective plate, thereby causing the first body to retract from the second body.
[0008] In one embodiment of the present invention, the second body is provided with a protrusion, and the rotating arm is provided with a buckle groove corresponding to the protrusion. The handle engages the protrusion through the buckle groove, thereby locking the second connector onto one side of the first connector.
[0009] In one embodiment of the present invention, the connecting rod includes guide grooves disposed on both sides of the limiting plate, and the pin moves along the guide grooves in the grooves.
[0010] In one embodiment of the present invention, each pin has a slot at the end facing the stop block, and the bottom end of the slot is a limiting surface. The pin of the latch slides in the guide groove until the limiting surface abuts against the inner wall of each guide groove, thereby limiting the depth of the pin extending into the card hole.
[0011] In one embodiment of the present invention, the connecting rod has a notch on the side facing the stop block.
[0012] In one embodiment of the present invention, the limiting plate is provided with a limiting groove, and the pressure plate is provided with a plurality of limiting blocks on the wall facing the pin, the limiting blocks protruding in the limiting groove.
[0013] In one embodiment of the present invention, the second body is provided with a protruding post on one side of the stop block, and the connecting rod is provided with a through hole corresponding to the position of the protruding post, the protruding post passing through the through hole and protruding in the through groove.
[0014] In one embodiment of the present invention, the pin has a groove on the side facing the protrusion, and the groove has a guide angle on the side away from the stop block.
[0015] In one embodiment of this utility model, the pressure plate is provided with a pressure-control part and multiple anti-slip textures.
[0016] Compared to known designs, the handle latch assembly of this invention is pivotally connected to the first and second connectors and is rotatable relative to them. The second body is inserted into the first body and includes a stop block and a locking hole. Furthermore, the handle latch assembly's locking mechanism includes a pin; under external force, the latch moves towards the stop block, causing the pin to extend into the locking hole. Because the pin remains in the locking hole in an undeformed state, breakage or permanent deformation that could cause it to lose its position is prevented. This provides a more reliable locking effect between the first and second connectors. Attached Figure Description

[0064] The detailed description and technical content of this utility model are explained below with reference to the accompanying drawings. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit this utility model.
[0065] Please refer to Figure 1 and Figure 2This invention provides a three-dimensional external view and an exploded three-dimensional view of the connector with a locking structure according to the present invention. The connector includes a first connector 10, a handle assembly 20, and a second connector 30. The handle assembly 20 is pivotally connected to the first connector 10 and the second connector 30 and is rotatable relative to them. The first connector 10 and the second connector 30 are locked together by the handle assembly 20, thereby preventing them from disengaging. The locking structure of the first connector 10 and the second connector 30 is described in more detail below.
[0066] The first connector 10 includes a first body 11 and a pair of first pivots 12 disposed on the first body 11. The handle assembly 20 includes a handle 21 and a latch 22. The handle 21 includes a pair of rotating arms 23 and a connecting rod 24 connecting the pair of rotating arms 23. Each rotating arm 23 is provided with a first pivot hole 231 and a second pivot hole 232. The handle 21 is movably engaged with the first body 11 by passing the pair of first pivots 12 through the first pivot holes 231 of the pair of rotating arms 23. Furthermore, the second connector 30 includes a second body 31 and a pair of second pivots 32 disposed on the second body 31. The pair of second pivots 32 pass through the second pivot holes 232 of the pair of rotating arms 23. Accordingly, the second body 31 is inserted into the first body 11, and the first connector 10 and the second connector 30 are locked together by the handle assembly 20.
[0067] In this embodiment, the second body 31 is provided with a stop block 311 and a locking hole 312, and a protrusion 313 is provided on one side of the stop block 311. Furthermore, the first connector 10 includes a protective plate 13 disposed on the first body 11, and the protective plate 13 is located on one side of the pair of first pivots 12. Also, the rotating arm 23 has an arc-shaped portion 233. When the handle 21 rotates to the first body 11, the arc-shaped portion 233 can push against the protective plate 13, thereby causing the first body 11 to retract from the second body 31.
[0068] Furthermore, the second body 31 is provided with a pair of protrusions 314. The rotating arm 23 is provided with a pair of latching grooves 230 corresponding to the protrusions 314. The handle 21 engages the protrusions 314 through the latching grooves 230, thereby locking the second connector 30 to one side of the first connector 10. This is the main locking mechanism between the first connector 10 and the second connector 30.
[0069] Please refer to another source. Figure 3 and Figure 4This is a perspective view and an exploded perspective view of the handle buckle assembly of this utility model. The handle buckle assembly 20 of this utility model includes a handle 21 and a lock 22. The handle 21 includes a rotating arm 23 and a connecting rod 24. The connecting rod 24 has a through groove 240 corresponding to the position of the stop block 311 and a limiting plate 241 located in the through groove 240, and the limiting plate 241 has a limiting groove 242. The connecting rod 24 includes a pair of guide grooves 243 disposed on both sides of the limiting plate 241. Furthermore, the lock 22 includes a pressure plate 221, a pair of pins 222 connected to the pressure plate 221, and a pin 223 disposed between the pair of pins 222. The lock 22 moves along the pair of guide grooves 243 through the pair of pins 222 in the through groove 240 and engages with the connecting rod 24. It is worth noting that the connecting rod 24 has a notch 244 on the side facing the stop block 311.
[0070] Please continue reading. Figure 5 and Figure 6 These are three-dimensional external schematic diagrams of the latch of this utility model from both sides. The latch 22 of this utility model includes a pressure plate 221, a pair of pins 222, and a pin 223. The pressure plate 221 is provided with a pressing part 224 and a plurality of anti-slip textures 225, and the pressure plate 221 has a plurality of limiting blocks 226 on the wall facing the pin 223. The setting of the pressing part 224 and the anti-slip textures 225 facilitates the user to apply force and move the latch 22. In addition, each pin 222 is L-shaped. Each pin 222 faces the stop block 311 (see reference). Figure 2 One end of the pin 223 is provided with a slot 220, and the bottom end of the slot 220 is a limiting surface 227. In addition, the pin 223 is provided with a groove 228 on the side facing the protrusion 313, and the groove 228 is provided with a guide angle 229 on the side away from the stop block 311.
[0071] It should be noted that the pin 223 of the latch 22 of this utility model is a cantilever and has elastic deformation force, so as to generate elastic deformation when moving, thereby passing over the protrusion 313 and being positioned.
[0072] Please refer to the following at the same time Figure 7 This is a cross-sectional view of the handle buckle assembly of this utility model. The connecting rod 24 of this utility model is provided with a through groove 240 and a limiting plate 241, and the limiting plate 241 is provided with a limiting groove 242. Furthermore, when the latch 22 of this utility model is engaged with the connecting rod 24, the limiting block 226 of the latch 22 will protrude into the limiting groove 242. Additionally, the position of the connecting rod 24 corresponding to the protrusion 313 (see...) Figure 2 Then a through hole 245 is provided.
[0073] Please refer to again Figures 8 to 10This diagram illustrates the rotation of the handle of this invention, a partial cross-sectional view of the handle buckle assembly during rotation, and a partial cross-sectional view of the handle buckle assembly after rotation. The handle buckle assembly 20 of this invention is pivotally connected to the first connector 10 and the second connector 30, and is capable of rotating relative to the first connector 10 and the second connector 30. Furthermore, the handle 21 of the handle buckle assembly 20 can rotate to the second body 31 of the second connector 30 and stop abutting against one side of the stop block 311, and the stop block 311 extends into the notch 244 of the connecting rod 24 (see Figure 24). Figure 1 ).
[0074] It should be noted that after the handle 21 of the handle assembly 20 is rotated to the second body 31, the protrusion 314 on the second body 31 will engage in the latch groove 230 of the handle 21. Accordingly, the second connector 30 is locked to one side of the first connector 10, completing the main locking between the second connector 30 and the first connector 10. It is worth noting that the protrusion 313 on the second body 31 will penetrate the through hole 245 of the connecting rod 24 and protrude into the through groove 240. At this time, the protrusion 313 will abut against the pin 223 of the latch 22 and stop in the groove 228 of the pin 223. Furthermore, the groove 228 of the pin 223 is provided with a guide angle 229. This guide angle 229 facilitates the pin 223 passing over the protrusion 313.
[0075] Please continue reading. Figure 11 This is a schematic diagram of the latch of the handle latch assembly of this utility model. Under an external force, the latch 22 of this utility model moves towards the stop block, causing the pin 223 to extend into the locking hole 312. It should be noted that the pin 222 of the latch 22 can slide in the guide groove 243 until the limiting surface 227 at the bottom of the slot 220 abuts against the inner wall of each guide groove, thereby limiting the depth of the pin 223 extending into the locking hole 312 (see Figure 243). Figure 4 and Figure 5 Furthermore, the pin 223 is prevented from moving out of the protrusion 313 by being blocked by the protrusion 313, thereby preventing the handle 21 from rotating. This is a secondary locking mechanism for the first connector 10 and the second connector 30, ensuring that the first connector 10 and the second connector 30 will not become detached (see...). Figure 1 ).
[0076] It should be noted that the latch 22 of this invention is provided with a pressing part 224 and anti-slip texture 225, which facilitates the user to apply force and move the latch 22. Furthermore, the latch 22 of the handle latch assembly 20 of this invention, through the elastic deformation of the pin 223, crosses the protrusion 313 located on the second body 31 and extends into the locking hole 312. The pin 223 will not move out of the protrusion 313 due to the blockage of the protrusion 313. Moreover, since the pin 223 is stopped in the locking hole 312 in an undeformed state, it can prevent the pin 223 from breaking or permanently deforming and losing its positioning. This provides a more reliable locking effect between the first connector 10 and the second connector 30.
[0077] The above description is only a preferred embodiment of the present utility model and is not intended to define the patent scope of the present utility model. Other equivalent changes that utilize the patent spirit of the present utility model should all fall within the patent scope of the present utility model.
