The elastic clamping piece then elastically returns to its original position, causing the clamping arm to push the conductor towards the conductor, clamping the conductor between the clamping arm and the conductor. Simultaneously, the clamping arm pushes the pressure plate upwards, causing the button to reset. The pressure plate includes a pressure plate and an arc-shaped hook; the pressure plate flips up and down via a rotating shaft. This invention replaces the linear drive method with a rotary drive mechanism, providing a stable and smooth driving force, improving the operating feel, and extending service life.

Description

Technical Field

[0001] This invention relates to a connection terminal. Background Technology

[0002] As a fundamental component in the field of electrical connections, connector terminals play a crucial role in achieving reliable electrical connections between conductors and conductive bodies in various electronic devices, electrical installations, and circuit systems. With the development of modern industry and the continuous expansion of application scenarios, higher demands are placed on the ease of use and operational reliability of connector terminals. A connector terminal typically includes a body, a conductive body disposed within the body, an insertion port on the side, and an elastic clamping piece. The conductor is inserted through the insertion port to achieve electrical connection with the conductive body, while the elastic clamping piece maintains a stable electrical connection between the conductor and the conductive body. In existing technologies, the operating mechanism of connector terminals often uses a button to drive the elastic clamping piece to elastically deform and clamp and release the conductor. However, existing button-driven methods are all linear motion structures moving in a straight up-and-down motion. This simple up-and-down movement has significant shortcomings in practical applications. Due to the lack of effective guiding and limiting mechanisms in linear motion, the contact motion between the linear motion and the elastic clamping piece is not stable enough, easily causing wobbling or deviation during the driving process. This results in uneven and unsmooth compression and relaxation of the elastic clamping piece, affecting the smoothness and stability of the overall linkage operation. Summary of the Invention

[0003] This invention discloses a connection terminal designed to solve the aforementioned problems.

[0004] The present invention adopts the following solution:

[0005] A connection terminal includes a body, a conductor disposed within the body, and an insertion port disposed on the side of the body. The insertion port is configured to allow a conductor to be inserted and electrically connected to the conductor. An elastic clamping piece is also disposed within the body to maintain the electrical connection between the conductor and the conductor. The terminal also includes a button and a pressure plate disposed on the body. When the button is pressed down, it drives the pressure plate to flip downwards within the body, thereby disengaging the clamping arm of the elastic clamping piece from the conductor, allowing the conductor to be inserted between the clamping arm and the conductor. The elastic return of the elastic clamping piece drives the clamping arm to move in the direction of conductor insertion, clamping the conductor between the clamping arm and the conductor. Simultaneously, the clamping arm can also push the pressure plate upwards, causing the button to return to its original position.

[0006] In this embodiment of the invention, the pressure plate includes a pressure plate, one end of which is provided with an arc-shaped hook, and a rotating shaft is provided inside the body. The hook is configured to be placed in the space around the rotating shaft so that the pressure plate can rotate up and down around the rotating shaft inside the body.

[0007] In this embodiment of the invention, a driving plate is provided at the front end and / or rear end of the pressure plate. A first arc-shaped surface is provided on the side of the driving plate facing the insertion port, and a second arc-shaped surface is provided in the main body located on the front and rear sides of the insertion port. The first arc-shaped surface can abut and cooperate with the second arc-shaped surface to guide the pressure plate to flip up and down.

[0008] In this embodiment of the invention, the pressure plate is provided with an oblong hole, and the lower end of the button is provided with a connecting post. The outer diameter of the connecting post can be adapted to the groove width of the oblong hole. The pressure plate can be flipped up and down to allow the connecting post to move within the oblong hole.

[0009] In this embodiment of the invention, the lower end of the connecting post is provided with a flange protruding outward, the flange is provided with a guide slope, and the connecting post is provided with a slot; when the connecting post is inserted into the waist-shaped hole, the guide slope abuts against the side wall of the waist-shaped hole, so that the post body of the connecting post shrinks into the slot and deforms, so that the flange is placed and abuts against the lower side wall of the waist-shaped hole; the body is also provided with a guide groove, and the button is provided with a guide block that can be placed in the guide groove, so that the button can move up and down relative to the body.

[0010] In this embodiment of the invention, the clamping arm is provided with a first tongue plate that is subjected to pressure on its front and rear sides, the clamping arm is disposed between two driving plates, and the lower end face of the driving plate is provided with a contacting fit that can maintain contact with the first tongue plate.

[0011] In this embodiment of the invention, the lower end face of the driving plate is sequentially provided with a first arc segment, a straight segment, and a second arc segment; when the pressure plate is not driven to flip downward by the button: the first tongue is disposed at the junction of the first arc segment and the straight segment, and a first abutting part that protrudes downward relative to the straight segment is formed on the driving plate at the first arc segment. The first abutting part is configured to prevent the first tongue from disengaging from the lower end face of the driving plate, and the second arc segment is configured to form an upwardly recessed groove on the lower end face of the driving plate. The groove is configured to prevent the first tongue from disengaging from the lower end face of the driving plate.

[0012] In this embodiment of the invention, when the pressure plate is driven to flip downward by a button: the first tongue is configured to move on a straight segment until the first tongue abuts against the second arc segment, thus completing the downward flip of the pressure plate; when the pressure plate is not flipped downward, the pressure plate is tilted and the straight segment is horizontal; when the pressure plate completes the downward flip, the pressure plate is horizontal and the straight segment is tilted.

[0013] In this embodiment of the invention, the sidewall on the other side of the driving plate is provided with a top surface, and a groove recessed towards the insertion port is provided above the top surface; the elastic clamping plate also includes a trigger arm disposed on the other side of the clamping arm, and a snap-fit ​​piece is formed on the front and rear sides of the upper end of the trigger arm; when the pressure plate is not flipped downward, the snap-fit ​​piece is configured to maintain abutment with the top surface; when the pressure plate is flipped downward by pressing the button, the upper end of the trigger arm is configured to swing towards the insertion port due to elastic deformation, so that the snap-fit ​​piece falls into the groove and prevents the clamping arm from elastically resetting.

[0014] In this embodiment of the invention, the conductor is configured to be horizontally inserted into the body through the insertion port, so that the conductor and the conductive body in contact with it are arranged in parallel. When the conductor is inserted into the body, the trigger arm located at the snap-fit ​​tab is vertically arranged in the body. When the conductor is inserted into the body and pushes the snap-fit ​​tab out of the slot, the clamping arm elastically resets and moves upward to clamp and fix the conductor on the lower end surface of the conductive body. At the same time, the clamping arm pushes the pressure plate button to move upward and reset, and the top surface returns to the abutting engagement with the snap-fit ​​tab, so that both the top surface and the snap-fit ​​tab are inclinedly arranged in the body.

[0015] This invention provides a connection terminal with the following advantages: 1. By setting a rotary drive mechanism, the pressure plate rotates around the rotation axis, driving the compression and relaxation of the elastic clamping piece with a fixed rotation radius. The pressure plate and the elastic clamping piece move in a relative sliding frictional manner, providing a stable and smooth up-and-down driving force for the button, avoiding the jamming and shaking problems that are prone to occur in the straight up-and-down driving method. 2. The segmented structure of the lower end face of the drive piece and its cooperation with the first tongue piece realize a cam-type curved surface transmission, making the pressure transmission smoother and improving the smoothness and stability of the linkage operation of the button, pressure plate, and elastic clamping piece. 3. The self-locking function is achieved through the locking cooperation of the slot and the locking piece. When the button is pressed down and released, the pressure plate can remain open, waiting for the conductor to be inserted. 4. After the conductor is inserted, the snap-fit ​​tab is automatically triggered to disengage from the slot, and the elastic clamping tab automatically resets and clamps the conductor. This achieves convenient operation of keeping the conductor open when pressed down and automatically clamping it upon insertion. The insertion and clamping of the conductor can be completed with just one hand, which simplifies the operation process, improves the operating feel, and extends the service life of the connection terminal.

[0026] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0027] Referring to the accompanying drawings, a connection terminal 100 according to an embodiment of the present invention includes a body 1, a conductor 2, an elastic clamping piece 3, a button 4, and a pressure plate 5. The conductor 2 is disposed within the body 1, and the conductor 2 is used to electrically connect with an inserted conductor 6. An insertion port 101 is disposed on the side of the body 1, allowing the conductor 6 to be inserted and electrically connected to the conductor 2. Preferably, there is one insertion port on each of the two sides of the body, with conductors inserted into each port respectively, and the conductor in the middle electrically connecting the two inserted conductors. The elastic clamping piece 3 is also disposed within the body 1, and the elastic clamping piece 3 is used to maintain the stability of the electrical connection between the conductor 6 and the conductor 2. The body 1 is also provided with a button 4 and a pressure plate 5. The button 4 is operated by the user, and the pressure plate 5 rotates under the drive of the button 4 to control the working state of the elastic clamping piece 3.

[0028] By pressing button 4, the pressure plate 5 is driven to flip downwards within the body 1. The flipping motion of the pressure plate 5 drives the clamping arm 31 of the elastic clamping piece 3 to move downwards, separating the clamping arm 31 from the conductor 2, thereby creating a space between the clamping arm 31 and the conductor 2 for the conductor 6 to be inserted. When the conductor 6 is inserted, the elastic reset of the elastic clamping piece 3 drives the clamping arm 31 to move upwards, pushing the conductor 6 towards the conductor 2, clamping the conductor 6 between the clamping arm 31 and the conductor 2. At the same time, the upward movement of the clamping arm 31 pushes the pressure plate 5 to flip upwards, and drives the button 4 to reset upwards, completing the entire insertion and clamping operation process.

[0029] The pressure plate 5 includes a pressure plate 51, one end of which is provided with an arc-shaped hook 52. A rotating shaft 103 is provided inside the body 1, and the hook 52 is located in the space surrounding the rotating shaft 103, allowing the pressure plate 5 to rotate up and down within the body 1 around the rotating shaft 103. When the button 4 is pressed down, the button 4 drives one end of the pressure plate 51 to move downwards, causing the pressure plate 51 to rotate downwards around the rotating shaft 103. When the elastic clamping piece 3 elastically resets, the clamping arm 31 moves upwards, pushing the other end of the pressure plate 5 upwards, causing the pressure plate 51 to rotate in the opposite direction around the rotating shaft 103, returning the pressure plate 51 to its initial tilted state, thus achieving the upward rotation and reset of the pressure plate 5. This rotational drive method allows the pressure plate 5 to rotate around the rotating shaft 103, driving the compression and relaxation of the elastic clamping piece 3 with a fixed rotation radius, achieving a stable and smooth transmission of up and down driving force, avoiding the jamming and shaking problems that are prone to occur in straight up and down driving methods.

[0030] Both the front and rear ends of the pressure plate 51 are provided with driving plates 53. The side of the driving plate 53 facing the insertion port 101 has a first arc-shaped surface 531, and the body 1 located on the front and rear sides of the insertion port 101 has a second arc-shaped surface 104. The first arc-shaped surface 531 and the second arc-shaped surface 104 abut against each other to guide the pressure plate 5 during its vertical rotation. When the pressure plate 5 rotates around the rotation axis 103, the first arc-shaped surface 531 on the driving plate 53 slides along the second arc-shaped surface 104 on the body 1. The radii of curvature of the first arc-shaped surface 531 and the second arc-shaped surface 104 match, ensuring that the pressure plate 5 moves along a predetermined trajectory during rotation, avoiding deviation or wobbling. The driving plates 53 are located at the front and rear ends of the pressure plate 51, making the rotation movement of the pressure plate 5 more stable and balanced. The driving plates 53 on both sides slide simultaneously along their respective second arc-shaped surfaces 104, ensuring that the pressure plate 5 does not tilt or twist.

[0031] The pressure plate 51 has an oblong hole 511 extending along the flipping direction of the pressure plate 5. A connecting post 41 is located at the lower end of the button 4. The outer diameter of the connecting post 41 matches the groove width of the oblong hole 511. When the pressure plate 5 flips up and down within the body 1, the connecting post 41 moves within the oblong hole 511. This design achieves a flexible connection between the button 4 and the pressure plate 5, allowing the connecting post 41 to move relative to the pressure plate 511 when it flips, avoiding motion interference that might occur with a rigid connection. The groove width of the oblong hole 511 is slightly larger than the outer diameter of the connecting post 41, allowing the connecting post 41 to slide smoothly within the oblong hole 511. Simultaneously, the length direction of the oblong hole 511 is adapted to the flipping trajectory of the pressure plate 5, ensuring that the connecting post 41 can move freely within the oblong hole 511 when the button 4 is pressed down, without restricting the flipping angle of the pressure plate 5.

[0032] The lower end of the connecting post 41 has a flange 411 protruding outwards, and a guide slope 412 is provided on the flange 411. The connecting post 41 has a slot 413. When the connecting post 41 is inserted into the oblong hole 511, the guide slope 412 abuts against the side wall of the oblong hole 511, and the inclined surface of the guide slope 412 guides the connecting post 41 smoothly into the oblong hole 511. Under the interaction of the guide slope 412 and the side wall of the oblong hole 511, the column of the connecting post 41 contracts and deforms into the slot 413. The existence of the slot 413 gives the connecting post 41 the ability to elastically deform, and the diameter of the column temporarily decreases. After the flange 411 passes through the oblong hole 511, the deformation of the connecting post 41 returns to normal, and the flange 411 is placed and abuts against the lower side wall of the oblong hole 511, realizing the detachable flexible connection between the button 4 and the pressure plate 5. This snap-fit ​​connection structure facilitates the assembly and disassembly of the button 4 and the pressure plate 5, while ensuring the reliability of the connection strength. The main body 1 is also provided with a guide groove 102, and the button 4 is provided with a guide block 42. The guide block 42 is placed within the guide groove 102 and can slide up and down within the guide groove 102. This structure allows the button 4 to move only linearly up and down relative to the main body 1.

[0033] The clamping arm 31 has pressure-bearing first tongues 311 on both its front and rear sides. The clamping arm 31 is positioned between two driving plates 53, located on its front and rear sides respectively. The lower end face of the driving plate 53 abuts against the first tongues 311. When the pressure plate 5 flips, the lower end face of the driving plate 53 presses against or releases the first tongues 311, thereby driving the clamping arm 31 to move up and down. The clamping arm 31 is positioned between the two driving plates 53 and is driven simultaneously by both sides, making the movement of the clamping arm 31 more stable and reliable, preventing tilting or jamming. The lower end face of the driving plate 53 has surface contact with the first tongues 311, resulting in a large contact area and uniform pressure distribution, which helps extend the service life of the clamping arm 31.

[0034] The lower end face of the drive plate 53 is sequentially provided with a first arc-shaped segment 532, a straight segment 533, and a second arc-shaped segment 534, which are connected sequentially to form a continuous lower end face contour. When the pressure plate 5 is not driven downward by the button 4, i.e., when the pressure plate 5 is in its initial state, the first tongue 311 is located at the junction of the first arc-shaped segment 532 and the straight segment 533, which is a turning point of the lower end face of the drive plate 53. The drive plate 53 at the first arc-shaped segment 532 is provided with a first abutment 535 that protrudes downward relative to the straight segment 533. The first abutment 535 forms a slightly downward protruding structure, which is used to prevent the first tongue 311 from detaching from the lower end face of the drive plate 53 when no force is applied, ensuring that the clamping arm 31 remains in the preset position. A recessed groove 536 is formed on the lower end face of the drive piece 53 at the second arc segment 534. When the first tongue piece 311 is located at the second arc segment 534, the first tongue piece 311 is embedded in the groove 536. The side wall of the groove 536 forms a lateral limit on the first tongue piece 311 to prevent the first tongue piece 311 from dislodging from the lower end face of the drive piece 53.

[0035] When the pressure plate 5 is driven to flip downward by the button 4, the first tongue 311 first moves from the first arc segment 532 to the straight segment 533. The horizontal setting of the straight segment 533 ensures that the first tongue 311 is subjected to uniform pressure when moving on the straight segment 533. When the first tongue 311 moves to the junction of the straight segment 533 and the second arc segment 534, the first tongue 311 enters the second arc segment 534. As the drive plate 53 continues to flip, the first tongue 311 gradually enters the groove 536 until the first tongue 311 abuts and engages with the second arc segment 534, at which point the pressure plate 5 completes its downward flip.

[0036] In the initial state before the pressure plate 5 flips downwards, the pressure plate 51 is tilted, and the straight segment 533 remains horizontal, parallel to the horizontal plane. After the pressure plate 51 completes its downward flip, i.e., when the pressure plate 5 flips to its maximum angle, the pressure plate 51 becomes horizontal. At this time, the lower end surface of the drive plate 53 also changes relative to the horizontal plane, and the straight segment 533 tilts relative to the horizontal plane, no longer maintaining a horizontal state. Through the segmented curved surface structure of the lower end surface of the drive plate 53 and its cooperation with the first tongue 311, a cam-type curved surface transmission is achieved, making pressure transmission smoother and avoiding impacts and vibrations caused by sudden pressure changes.

[0037] A top surface 537 is provided on the side wall of the other side of the drive plate 53, and a groove 538 recessed towards the insertion port 101 is provided above the top surface 537. The elastic clamping plate 3 also includes a trigger arm 32 provided on the other side of the clamping arm 31. The trigger arm 32 and the clamping arm 31 are arranged adjacent to each other and together form the overall structure of the elastic clamping plate 3. Both arms have elastic deformation capability. The front and rear sides of the upper end of the trigger arm 32 extend to form a snap-fit ​​piece 321. The snap-fit ​​piece 321 is provided on the front and rear sides of the upper end of the trigger arm 32 and respectively cooperates with the top surface 537 of the drive plate 53. When the pressure plate 5 is not flipped downward, the snap-fit ​​piece 321 and the top surface 537 are in abutting cooperation. At this time, both the snap-fit ​​piece 321 and the top surface 537 are in an inclined state in the body 1, and the trigger arm 32 is supported by the top surface 537 to maintain the inclination. When the pressure plate 5 is flipped downwards by pressing button 4, the upper end of the trigger arm 32 swings towards the insertion port 101 due to elastic deformation. Under the action of elastic force, the trigger arm 32 twists, causing the locking piece 321 to fall into the slot 538. The locking piece 321 and the slot 538 cooperate to form a self-locking structure, which can prevent the clamping arm 31 from elastically returning to its original position when no other external force is applied, thereby realizing the self-locking retention function after the pressure plate 5 is flipped.

[0038] Conductor 6 is horizontally inserted into body 1 through insertion port 101, with the insertion direction perpendicular to the latching tab in this state. Conductor 6 is arranged parallel to conductor 2. When conductor 6 is inserted into body 1, trigger arm 32 located at latching tab 321 is vertically arranged inside body 1, and trigger arm 32 is in a trigger standby state. When conductor 6 is inserted into body 1 through insertion port 101, the insertion end of conductor 6 moves, pushing trigger arm 32 at latching tab 321. The swing of trigger arm 32 causes latching tab 321 to disengage from slot 538. After latching tab 321 disengages from slot 538, clamping arm 31 loses its self-locking restriction and elastically resets and moves upward under the action of elastic restoring force. After the upper end of clamping arm 31 moves upward, it abuts against conductor 2, clamping and fixing conductor 6 to the lower end surface of conductor 2, realizing the electrical connection between conductor 6 and conductor 2. At the same time, the upward movement of clamping arm 31 pushes pressure plate 5 and button 4 to move upward and reset, and drive plate 53 gradually returns to its initial state. During this process: the top surface 537 returns to the abutting engagement state with the snap-fit ​​piece 321. At this time, both the top surface 537 and the snap-fit ​​piece 321 are tilted and arranged inside the body 1. The entire connection terminal 100 returns to its initial state, ready for the next operation.

[0039] The connection terminal 100 of this embodiment of the invention has the following beneficial effects: By setting a rotary drive mechanism, the pressure plate 5 rotates around the rotation axis 103, driving the compression and relaxation of the elastic clamping piece 3 with a fixed rotation radius. The pressure plate 5 and the elastic clamping piece 3 move in a relatively sliding frictional manner, providing a stable and smooth up-and-down driving force for the button 4, avoiding the jamming and shaking problems that are easy to occur in the straight up-and-down driving method. The segmented structure of the lower end face of the drive piece 53 cooperates with the first tongue piece 311 to realize the cam-type curved surface transmission, making the pressure transmission smoother and improving the smooth and stable performance of the linkage operation of the button 4, the pressure plate 5, and the elastic clamping piece 3. The self-locking retention function is realized by the locking cooperation between the slot 538 and the locking piece 321. When the button 4 is pressed down and released, the pressure plate 5 can remain open, waiting for the conductor 6 to be inserted. After the conductor 6 is inserted, the snap-fit ​​tab 321 is automatically triggered to disengage from the slot 538, and the elastic clamping tab 3 automatically resets and clamps the conductor 6. This achieves a convenient operation of keeping it open when pressed down and automatically clamping it when inserted. The insertion and clamping of the conductor 6 can be completed by pressing with one hand, which simplifies the operation process, improves the operating feel, and extends the service life of the connecting terminal 100.

The elastic clamping plate also includes a trigger arm on the other side of the clamping arm, and a snap-fit ​​piece extends from the front and rear sides of the upper end of the trigger arm. When the pressure plate is not flipped downward, the snap-fit ​​piece is configured to maintain contact with the top surface. When the pressure plate is flipped downward by pressing the button, the upper end of the trigger arm is configured to swing in the direction of insertion due to elastic deformation, so that the snap-fit ​​piece falls into the slot and prevents the clamping arm from elastically resetting.

10. A connecting terminal according to claim 9, characterized in that, The conductor is configured to be horizontally inserted into the body through the insertion port, so that the conductor and the conductive body in contact with it are arranged in parallel. When the conductor is inserted into the body, the trigger arm located at the snap-fit ​​is vertically arranged in the body. When the conductor is inserted into the body and pushes the snap-fit ​​to disengage from the slot, the clamping arm elastically resets and moves upward to clamp and fix the conductor on the lower end face of the conductive body. At the same time, the clamping arm pushes the pressure plate button to move upward and reset, and the top surface returns to abutting engagement with the snap-fit, so that both the top surface and the snap-fit ​​are inclinedly arranged in the body.
