Description

Technical Field

[0001] The utility model relates to a terminal block, in particular to a quick-locking and quick-taking handle structure of the terminal block. Background Art

[0002] After the plug-in and fixed ends of a pluggable terminal block are connected, a locking mechanism secures them in place, preventing them from coming loose during use. A space-saving locking mechanism employs a switch handle on the plug-in end and a slot on the fixed end. The switch handle snaps into the slot when the plug-in and fixed ends are connected, locking the plug-in and fixed ends together. Currently, switch handles are held in place by the upper end of the plug-in end body, leveraging the handle's inherent elasticity to achieve springback. Because the clamping portion of the plug-in end body is made of thin-walled plastic, the clamping effect degrades or even disappears over time, leading to handle springback failure. Utility Model Content

[0005] As a further improvement of the present invention, the elastic part is an elastic cantilever structure integrally formed on the side surface of the plug-in end body facing away from the welding direction to avoid the surface of the recessed portion. The elastic cantilever structure of the elastic part can swing elastically synchronously with the handle, and the free end of the elastic cantilever structure of the elastic part always presses against the side surface of the handle in the direction of elastic deformation and provides auxiliary elastic reset force to the handle.

[0006] As a further improvement of the present invention, an avoidance recess is provided on one side surface of the plug-in end body facing away from the welding direction, and the handle forms an elastic cantilever structure with the other end as the free end. The second snap structure is an inverted hook provided on the other end of the handle. The first snap structure on the fixed end body includes an open groove arranged parallel to and extending in the same direction as the plug-in groove, and a groove or protrusion provided on the side wall of the open groove. The other end of the handle and the hook thereon can be inserted into the open groove on the fixed end body, and the hook can hook with the groove or protrusion on the side wall of the open groove under the action of the elastic reset force of the handle itself. Pressing the disengagement pressing part can drive the handle to swing elastically so that the hook at its other end is disengaged from the groove or protrusion on the side wall of the open groove.

[0007] As a further improvement of the present invention, the protrusion on the side wall of the opening groove is also an inverted structure, and when the hook at the free end of the cantilever structure at the other end of the handle is inserted into the opening groove, its inclined surface contacts the inclined surface of the protrusion.

[0008] As a further improvement of the present invention, at least two sub-cantilever structures are provided in parallel and spaced apart at the other end of the handle, and each sub-cantilever structure is provided with an inverted hook. The first hook structure on the side wall of the fixed end body includes at least two open grooves, and each sub-cantilever structure can be inserted into each open groove one by one, and the hooks on the sub-cantilever structures are respectively engaged and connected with the grooves or protrusions on the inner side walls of each open groove.

[0009] As a further improvement of the present invention, the structure in which one end of the handle is fixedly mounted on a side surface of the plug-in end body facing away from the welding direction is as follows: a fixed slot extending along the plug-in direction is provided on a side surface of the plug-in end body facing away from the welding direction, and a handle blocking rib perpendicular to the plug-in direction is also provided on a side surface of the plug-in end body facing away from the welding direction; a plug-in piece is provided at one end of the handle, and the plug-in piece can be inserted into the fixed slot on one side surface of the plug-in end body; a blocking step is also provided on the side wall of the handle; the handle blocking rib on one side surface of the plug-in end body blocks the blocking step surface on the side wall of the handle, thereby preventing the plug-in piece of the handle from falling out of the open end of the fixed slot.

[0010] As a further improvement of the present invention, a raised fulcrum is provided on the side wall at one end of the handle, and the raised fulcrum is tightly against the side wall surface of the opening of the fixed slot. The raised fulcrum enables the side of the plug-in piece at one end of the handle facing away from the raised fulcrum to be tightly against the other side wall surface of the fixed slot, and the handle can swing elastically with the raised fulcrum as the fulcrum.

[0011] As a further improvement of the present invention, at least two fixed slots are provided in parallel and spaced apart on one side of the plug-in end body, and two plug-in pieces are provided in parallel and spaced apart on one end of the handle, and each plug-in piece is inserted into each fixed slot one by one. The trip pressing portion is a thickened boss provided between the two ends of the handle, and a pressing surface for pressing by a finger is formed on the surface of the thickened boss, and a side wall at one end of the thickened boss is stopped on the end face of the opening of the fixed slot.

[0012] As a further improvement of the present invention, at least two raised handle blocking ribs are provided on one side surface of the plug-in end body at intervals along the width direction of the handle, and the handle is provided with at least two notch structures arranged at intervals along its width direction.

[0013] As a further improvement of the present invention, the handle blocking rib is formed with a guiding slope toward the other end of the handle.

[0014] The beneficial effects of the present invention are as follows: the handle of the present invention not only forms an elastic cantilever structure itself to generate rebound, but also has an elastic part provided on the plug-in end body, which provides auxiliary rebound force to the handle. After long-term use, even if the plastic clamping effect of the plug-in end body is reduced or lost, the handle can still rebound under the action of the elastic part. Moreover, after the plug-in piece at one end of the handle of the present invention is inserted into the fixed slot of the plug-in end body, the handle blocking rib on the plug-in end body blocks the blocking step on the handle to achieve fixed positioning of one end of the handle on the plug-in end body. Even after long-term use, one end of the handle will not loosen from the plug-in end body, and the stable positioning of one end of the handle can be maintained for a long time, thereby improving the service life of the handle and the locking force after the terminal block is plugged in.

[0024] Embodiment: A terminal block quick lock and quick take handle structure, comprising a fixed end body 1, a plug-in end body 2 and a handle 3, wherein the plug-in end body 21 can be inserted into the plug-in slot 11 of the fixed end body 1, and a first buckle structure is provided on the side of the fixed end body 1 facing away from the welding direction, and one end of the handle 3 is fixedly mounted on the side of the plug-in end body 2 facing away from the welding direction, and a second buckle structure is provided on the other end of the handle 3, and the second buckle structure of the handle 3 is inserted into the plug-in slot 11 of the fixed end body 1 when the plug-in end body 21 of the plug-in end body 2 is inserted into the plug-in slot 11 of the fixed end body 1. 1, and can be buckled and connected with the first buckle structure when in the plug-in slot 11. When the first buckle structure and the second buckle structure are buckled and connected, they can prevent the plug-in column 21 from exiting the plug-in slot 11. The handle 3 is also provided with a disengagement pressing portion 31. Pressing the disengagement pressing portion 31 can drive the handle 3 to elastically deform so that the second buckle structure at the other end is disengaged from the first buckle structure. An elastic member 22 is also provided on the side surface of the plug-in end body 2 facing away from the welding direction. The elastic member 22 can provide the handle 3 with an auxiliary elastic force to restore it to its original state when not affected by external force.

[0025] When the plug-in column 21 of the plug-in end body 2 is inserted into the plug-in slot 11 of the fixed end body 1, the second snap structure on the handle 3 is snapped together with the first snap structure on the fixed end body 1, so that the plug-in end cannot be directly pulled out from the fixed end. When the plug-in end needs to be pulled out from the fixed end, the disengagement pressing portion 31 on the handle 3 is first pressed to cause the handle 3 to elastically deform, thereby disengaging the first snap structure from the second snap structure, and at the same time pulling out the plug-in end body 2. After the plug-in end body 2 is pulled out, the disengagement pressing portion 31 on the handle 3 is released, and the handle 3 quickly returns to its original state under the action of its own elastic force and the auxiliary elastic force of the elastic member 22. The handle 3 of the above structure can quickly return to its initial state when the disengagement pressing portion 31 is pressed by an external force. Even if the elasticity of the handle 3 itself is reduced after long-term use, it will automatically return to its initial state under the action of the auxiliary elastic force of the elastic member 22, without causing the snap connection to fail.

[0026] The elastic member 22 is an elastic cantilever structure integrally formed on the side of the plug-in terminal body 2 facing away from the welding direction, avoiding the surface of the recessed portion 23. The elastic cantilever structure of the elastic member 22 can swing synchronously with the handle 3, and the free end of the elastic cantilever structure of the elastic member 22 always abuts the side of the handle 3 in the direction of elastic deformation, providing auxiliary elastic restoring force to the handle 3. In addition to using the elastic cantilever structure to elastically support the handle 3 and provide a reversible elastic restoring force, the elastic member can also be a spring or spring clip mounted on the plug-in terminal body.

[0027] The plug-in end body 2 is provided with an avoidance recess 23 on one side surface facing away from the welding direction, and the handle 3 forms an elastic cantilever structure with the other end as the free end. The second snap structure is an inverted hook 32 provided on the other end of the handle 3. The first snap structure on the fixed end body 1 includes an open groove 12 arranged parallel to and extending in the same direction as the plug-in groove 11 and a groove or protrusion 13 provided on the side wall of the open groove 12. The other end of the handle 3 and the hook 32 thereon can be inserted into the open groove 12 on the fixed end body 1, and the hook 32 can be hooked with the groove or protrusion 13 on the side wall of the open groove 12 under the action of the elastic reset force of the handle 3 itself. Pressing the disengagement pressing portion 31 can drive the handle 3 to swing elastically so that the hook 32 at the other end is disengaged from the groove or protrusion 13 on the side wall of the open groove 12. When the plug-in end body 2 and the fixed end body 1 are plugged together, the other end of the handle 3 is inserted into the open groove 12 on the fixed end body 1. When the hook 32 at the other end of the handle 3 enters the open groove 12, the elastic cantilever structure of the handle 3 will produce a certain elastic swing. When the hook 32 is opposite to the groove on the side wall of the open groove 12 or passes over the protrusion, under the action of the elastic reset force of the handle 3 itself, the hook 32 is hooked with the side wall of the groove or protrusion 13 to achieve a snap-fit ​​connection and positioning. The above structure is simple, and the snap-fit ​​connection is firm and stable. In addition, the first snap-fit ​​structure and the second snap-fit ​​structure can also be a slot and sliding pin matching structure, or a C-shaped slot and ball head plug-in structure, etc. This is an equivalent replacement that a technician in this field can easily think of based on this application, and it falls within the scope of protection of this application.

[0028] The protrusions on the sidewalls of the opening slot 12 are also inverted. When the hook 32 at the free end of the cantilever structure at the other end of the handle 3 is inserted into the opening slot 12, its inclined surface contacts the inclined surface of the protrusions. When the other end of the handle 3 is inserted into the opening slot 12, it contacts the protrusions on the sidewalls of the opening slot 12 through the inclined surface, allowing it to smoothly pass over the surface of the protrusions, achieving a snap-fit ​​connection.

[0029] At least two sub-cantilever structures 33 are provided in parallel and spaced apart at the other end of the handle 3, and each sub-cantilever structure 33 is provided with an inverted hook 32. The first hook structure on the side wall of the fixed end body 1 includes at least two open grooves 12. Each sub-cantilever structure 33 can be inserted into each open groove 12 one by one, and the hooks 32 on the sub-cantilever structures 33 are respectively engaged with the grooves or protrusions 13 on the inner wall of each open groove 12.

[0030] The structure in which one end of the handle 3 is fixedly mounted on a side surface of the plug-in end body 2 facing away from the welding direction is as follows: a fixed slot 24 extending along the plug-in direction is provided on a side surface of the plug-in end body 2 facing away from the welding direction, and a handle blocking rib 25 perpendicular to the plug-in direction is also provided on a side surface of the plug-in end body 2 facing away from the welding direction. A plug-in piece 35 is provided at one end of the handle 3, and the plug-in piece 35 can be inserted into the fixed slot 24 on one side surface of the plug-in end body 2. A blocking step is also provided on the side wall of the handle 3. The handle blocking rib 25 on one side surface of the plug-in end body 2 blocks the blocking step surface on the side wall of the handle 3, thereby preventing the plug-in piece 35 of the handle 3 from escaping from the open end of the fixed slot 24.

[0031] After the plug-in piece 35 at one end of the handle 3 is inserted into the fixed slot 24 on the plug-in end body 2, the circumferential side wall of the plug-in piece 35 is blocked by the fixed slot 24 to achieve circumferential positioning, and its length direction is blocked and positioned by the fixed slot 24 and the handle blocking rib 25. The handle blocking rib 25 not only achieves the blocking positioning of the handle 3, but also does not affect the up and down swinging of the handle 3. The design of the handle blocking rib 25 makes the handle 3 structure simpler and the positioning more firm and stable. In addition, one end of the handle 3 can also be directly integrally formed on the side wall of the plug-in end body 2, or fixed to the plug-in end body 2 by interference fit or riveting. This is an equivalent replacement structure that a person skilled in the art can easily think of based on this patent, and it falls within the scope of protection of this patent.

[0032] A raised fulcrum 34 is also provided on the sidewall of one end of the handle 3. This raised fulcrum 34 abuts against the surface of one sidewall of the opening of the fixed slot 24. This raised fulcrum 34 allows the side of the plug-in tab 35 at one end of the handle 3, facing away from the raised fulcrum 34, to abut against the surface of the other sidewall of the fixed slot 24, allowing the handle 3 to elastically swing about this raised fulcrum 34. This raised fulcrum 34 not only allows the plug-in tab at one end of the handle 3 to fit tightly and stably with the sidewall of the fixed slot 24, but also forms the fulcrum for the other end of the handle 3 to swing smoothly and elastically without being susceptible to breakage or damage.

[0033] At least two fixed slots 24 are provided in parallel and spaced relation on one side of the plug-in end body 2. Two plug-in tabs 35 are provided in parallel and spaced relation on one end of the handle 3. Each plug-in tab 35 is inserted into each fixed slot 24 in a one-to-one correspondence. The release pressing portion 31 is a thickened boss provided between the two ends of the handle 3. The surface of the thickened boss is formed with a pressing surface for finger pressure. The side wall of one end of the thickened boss abuts against the end surface of the opening of the fixed slot 24. The use of the thickened boss for the release pressing portion 31 can increase the pressing force strength of the handle 3 and prevent it from being damaged by pressure. A stepped surface is formed between the thickened boss and the plug-in tab 35 to form a stop with the end of the fixed slot 24, thereby achieving the positioning of the handle 3 along its length.

[0034] At least two raised handle blocking ribs 25 are provided on one side surface of the plug-in end body 2 at intervals along the width direction of the handle 3, and the handle 3 is provided with at least two notch structures 26 arranged at intervals along its width direction. The handle blocking ribs 25 are inserted into each notch structure 26 on the handle 3 one by one, and the side walls of each notch structure 26 on the handle 3 form a blocking step.

[0035] The handle blocking rib 25 is formed with a guiding slope toward the other end of the handle 3 .
