Description

Technical Field

[0001] This utility model relates to a pluggable terminal block, and more particularly to a terminal block press-lock hook type unlocking structure. Background Technology

[0002] A pluggable terminal block typically consists of a plug and a socket. When the plug's pins are inserted into the socket's slots, the elastic clips inside the pins engage the conductive pins in the slots, establishing electrical conductivity between the plug and socket. To prevent accidental removal, a locking mechanism is usually installed on both the plug and socket, preventing the plug from being pulled out by external force while the connection is established. Traditional locking mechanisms generally include a slot in the socket, a spring-loaded hook on the plug, and an unlocking handle. To remove the plug from the socket, the unlocking handle must first be operated to disengage the hook from the slot in the socket, and then the plug must be pulled out forcefully. This method requires two steps, making it inconvenient and structurally complex. Utility Model Content

[0003] To overcome the above-mentioned defects, this utility model provides a terminal block press-hook type unlocking structure. This terminal block press-hook type unlocking structure can not only ensure that the plug and socket maintain a stable connection during the insertion process, but also facilitate the quick separation of the plug and socket, and has a simple structure.

The socket is also provided with at least one locking hook slot, and a first buckle is provided on the side wall of the locking hook slot. The plug is provided with at least one locking hook that can move elastically, and a second buckle is provided on the locking hook. The locking hook can be inserted into the locking hook slot simultaneously when the insertion pin is inserted into the insertion slot. The second buckle on the locking hook can be engaged with the first buckle under the action of the locking hook's own elastic force. The plug is also provided with a press handle that can move within a set range. The press handle is connected to each locking hook. A press operation part is formed on the press handle. The press operation part is located on the side of the plug that protrudes from the outer side of the socket. Pressing the press operation part of the press handle can force the press handle to move in conjunction with the locking hook to overcome its own elastic force, thereby causing the second buckle to disengage from the first buckle.

[0005] As a further improvement of this utility model, the pressing handle is an elastic cantilever structure installed on the side wall of the plug. The pressing handle can swing elastically when pressed. The side wall of the pressing handle along its elastic swing direction is pressed against the side wall of the locking hook along its elastic movement direction, so that the locking hook can overcome its own elastic movement synchronously with the elastic swing of the pressing handle.

[0006] As a further improvement of this utility model, each locking hook groove is connected to the corresponding insertion groove. One end of the pressing handle is fixedly installed on the side wall of the insertion post opposite the locking hook. The other end of the pressing handle forms the free end of an elastic cantilever structure. The other end of the pressing handle is the pressing operation part. One end of the pressing handle can be inserted into the locking hook groove together with the locking hook.

[0007] As a further improvement of this utility model, a handle mounting protrusion is formed on the side wall of the plug-in post opposite to the lock hook.

[0043] Example: A terminal block press-lock hook-type release structure includes a plug 1 and a socket 2. The socket 2 has a plurality of insertion slots 21, and the plug 1 has a plurality of insertion pins 11. Each insertion pin 11 of the plug 1 can be inserted into each insertion slot 21 of the socket 2 to achieve electrical connection. The socket 2 also has at least one locking hook slot 22, and the side wall of the locking hook slot 22 has a first buckle. The plug 1 has at least one elastically movable locking hook 12, and the locking hook 12 has a second buckle. The locking hook 12 can insert the insertion pin 11 into the insertion slot 21. The plug 1 is simultaneously inserted into the slot 22 of the locking hook 12. The second buckle on the locking hook 12 can be engaged with the first buckle under the action of the locking hook 12's own elastic force. The plug 1 is also provided with a pressing handle 3 that can move within a set range. The pressing handle 3 is connected to each locking hook 12. A pressing operation part 31 is formed on the pressing handle 3. The pressing operation part 31 is located on the side of the plug 1 that is exposed outside the socket 2. Pressing the pressing operation part 31 of the pressing handle 3 can force the pressing handle 3 to move in conjunction with the locking hook 12 to overcome its own elastic force, thereby causing the second buckle to disengage from the first buckle.

[0044] When plug 1 and socket 2 are plugged in, the locking hook 12 on plug 1 simultaneously inserts into the locking hook 12 slot 22 on socket 2. Under the elastic force of the locking hook 12 itself, the second latch on the locking hook 12 automatically engages with the first latch on the side wall of the locking hook 12 slot 22, locking plug 1 and socket 2 together. Plug 1 cannot be removed from socket 2. To remove plug 1, simply grasp plug 1 and press the pressing operation part 31 of the pressing handle 3 located on one side of plug 1. When the hand 3 is pressed, it displaces on the plug 1, and the linkage hook 12 overcomes its own elastic force, causing the second buckle on the hook 12 to disengage from the first buckle on the side wall of the hook 12 groove 22. At this time, the plug 1 can be pulled out directly. The above structure avoids the need to first unlock the plug 1 and socket 2, then lock the handle, and then pull out the plug 1. Moreover, after the plug 1 is pulled out, the pressing handle 3 and the hook 12 on it will automatically reset as long as the plug 1 is released, without the need to disengage the pressing handle 3.

[0045] The pressing handle 3 is an elastic cantilever structure installed on the side wall of the plug 1. The pressing handle 3 can swing elastically when pressed. The pressing handle 3 is pressed against the side wall of the locking hook 12 along its elastic movement direction along its side wall, so that the locking hook 12 can overcome its own elastic force movement synchronously with the elastic swing of the pressing handle 3.

[0046] The cantilever structure of the pressing handle 3 allows it to swing left and right, thereby pressing the locking hook 12 against its contact point and causing the locking hook 12 to retract. This pressing handle 3 forms a lever structure, using a long lever arm to easily move the locking hook 12. Therefore, the pressing handle 3 only needs to be pressed lightly to unlock the plug 1 and the socket 2. The elastic force of the pressing handle 3 itself also allows it to automatically reset after the pressure is lost, without putting a burden on the elastic force of the locking hook 12. In addition to the cantilever structure, the pressing handle 3 can also be a left-right translational motion structure, with a spring extending in the left-right direction providing elastic force to the pressing handle 3. Alternatively, the pressing handle 3 can be hinged to the side wall of the plug 1 to form a lever structure, with the pressing operation part 31 located on one side of the hinge fulcrum and the other end of the hinge fulcrum contacting the locking hook 12 for pressing. This is an equivalent replacement structure that is easily conceived by those skilled in the art based on this application and falls within the protection scope of this application.

[0047] Each locking hook 12 slot 22 is connected to its corresponding plug slot 21. One end of the pressing handle 3 is fixedly installed on the side wall of the plug post 11 opposite to the locking hook 12. The other end of the pressing handle 3 forms a free end of an elastic cantilever structure and is a pressing operation part 31. One end of the pressing handle 3 can be inserted into the locking hook 12 slot 22 together with the locking hook 12. There can be one or more locking hook 12 slots 22, which can be connected to one or more plug slots 21, and occupy little space on the socket 2.

[0048] A handle mounting protrusion 111 is formed on the side wall of the plug post 11 opposite to the locking hook 12. A handle insertion hole 221112 is formed on the handle mounting protrusion 111, and one end of the handle is fixedly inserted into the handle insertion hole 221112. The press handle 3 is installed on the side wall of the plug post 11 by plug-in assembly. The press handle 3 forms a detachable structure, and different specifications of press handle 3 can be selected according to the insertion and removal force of different plugs 1.

[0049] The handle insertion hole 221112 has a handle limiting groove 113 on its side wall, and the pressing handle 3 has an inverted protrusion 32 on one side wall. The inverted protrusion 32 on the pressing handle 3 can be locked in the handle limiting groove 113 to prevent one end of the handle from exiting the handle insertion hole 221112. An inverted protrusion 32 is provided on the handle so that it engages with the handle limiting groove 113 on the side wall of the handle insertion hole 221112 to achieve stop positioning of the handle. In order to allow the pressing handle 3 to be inserted smoothly and also to allow the pressing handle 3 to be disassembled, it is best to form a chamfered inclined surface on the side wall of the side wall opposite to the side wall where the handle insertion hole 221112 and the handle limiting groove 113 are located. The inclined surface can avoid and guide the inverted protrusion 32 of the pressing handle 3. The handle limiting groove 113 is preferably set on the side of the pressing handle 3 away from the pressing operation part 31 to prevent the inverted protrusion 32 on the pressing handle 3 from disengaging from the handle limiting groove 113 when the pressing handle 3 is pressed.

[0050] The part of the pressing handle 3 that can be inserted into the groove 22 of the locking hook 12 is an L-shaped structure. One side wall of the L-shaped structure is inserted into the handle insertion hole 221112, and the other side wall of the L-shaped structure forms an elastic cantilever structure for pressing the locking hook 12. The pressing operation part 31 is fixedly connected to the other side wall of the L-shaped structure to form an integral part. Several raised anti-slip ribs 311 are formed on the surface of the pressing operation part 31.

[0051] The handle 3 is formed into an L-shaped structure. One side wall of the L-shaped structure forms an installation end that is inserted into the handle socket 221112. The other side wall of the L-shaped structure forms an elastically deformable cantilever structure and a pressing operation part 31 for pressing. Anti-slip ribs 311 are provided on the surface of the pressing operation part 31 to improve its friction coefficient. When the user presses it and pulls out the plug 1, it will not slip.

[0052] The first latch is an insertion hole 221 or slot on the side wall of the lock hook 12 groove 22, and the second latch is an insert 121 on the lock hook 12. The insert 121 can be inserted into the insertion hole 221 or slot on the side wall of the lock hook 12 groove 22 to prevent the latch from exiting the lock hook 12 groove 22. The first latch and the second latch are first fastened by plugging, or they can be fastened by hooking.

[0053] The push handle 3 has a clearance hole 33 on its side wall. The insert 121 on the hook 12 can pass through the clearance hole 33 and be inserted into the insertion hole 221 or slot on the side wall of the hook 12 groove 22. After passing through the clearance hole 33 on the side wall of the push handle 3, the insert 121 on the hook 12 is inserted into the insertion hole 221 or slot. In this way, the insert 121 also guides the movement of the push handle 3, ensuring that it is pressed against the end face of the hook 12 and preventing misalignment.

[0054] The locking hook 12 is an elastic cantilever structure integrally formed on the plug 1, and the second buckle is provided on the free end of the elastic cantilever structure of the locking hook 12. The locking hook 12 forms an elastic movement connection with the plug 1 by utilizing the cantilever structure. This structure is simple, does not require additional elastic elements, and can be integrally formed with the plastic shell of the plug 1. In addition, the locking hook 12 can also be on the plug 1 by utilizing a spring elastic component.

[0055] The locking hook 12 has an L-shaped structure. One arm of the L-shaped structure extends along the depth direction of the locking hook 12 groove 22 to form an elastic cantilever structure, and the other arm extends along the depth direction of the insertion hole 221 or slot on the side wall of the locking hook 12 groove 22. The insert 121 is provided on the end face of the other arm of the locking hook 12 L-shaped structure. By designing the locking hook 12 as an L-shaped structure, one arm is a cantilever structure that provides elastic swing, and the other arm forms a second buckle perpendicular to the insertion direction. This structure occupies little space and allows the insert 121 of the locking hook 12 to extend and retract basically along the direction of pulling out the plug 1, thus ensuring the stability of the locked state.
