Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a modular wiring terminal with multi-angle adjustment. Background Art

[0002] Terminal blocks are electrical accessories used to connect wires and are widely used in various electrical projects, making circuit connections simpler, safer, and more reliable. Currently, when connecting a single terminal block to the same circuit, the two ends are typically fixed at a fixed angle and direction. Even if the two ends of the terminal block can rotate relative to each other, the angle and direction of the connection can only be adjusted for the same circuit. The terminal block cannot be adjusted for the angles and directions of multiple different circuits. Furthermore, when connecting the circuits, screws and pressure plates are used to hold them together, resulting in low assembly and disassembly efficiency and the circuits easily detaching from the terminal block when adjusting the angle. Utility Model Content

[0003] The purpose of the utility model is to provide a modular terminal block with multi-angle adjustment, aiming to solve the technical problems existing in the prior art, such as the inability to adjust the angles and directions between the terminal blocks, the inability to adjust the connection angles and directions according to multiple groups of different lines, the low efficiency of line loading and unloading, and the easy detachment of the terminal blocks.

[0004] In order to solve the above technical problems, the present invention provides a modular terminal block with multi-angle adjustment, including: a connecting base with openings at both ends, terminal bases are rotatably provided at both ends of the connecting base, a wiring port is provided on the terminal base, and a clamping mechanism for placing and clamping the wire is provided in the wiring port, the clamping mechanism includes a clamping assembly, and a driving assembly and a reset assembly connected to the clamping assembly, and the two clamping mechanisms are electrically connected through a conductive assembly; the connecting base is also provided with a rotating clamping mechanism, the rotating clamping mechanism includes a clamping assembly and an angle assembly, the clamping assembly is used to connect the two modular terminal blocks, and the angle assembly is used to adjust the angle between the two modular terminal blocks.

[0005] The two terminal blocks can be rotatably connected to the connecting block, so that the same line can be installed on the terminal blocks at different angles and directions and electrically connected; the clamping mechanism drives the clamping assembly through the driving assembly to clamp the wire inserted into the wiring port, so that the wire is fastened in the wiring port. When the wire needs to be loosened, the reset assembly assists the driving assembly to make the clamping assembly loosen the wire. There is no need to use other tools to adjust the clamping mechanism, which is beneficial to improving the efficiency of wire loading and unloading; when multiple groups of lines need to be connected, the snap-on assemblies on multiple terminal blocks can be matched to form a terminal block row, and the number of terminal blocks can be adjusted as needed, which is beneficial to improving the adaptability to multiple groups of lines and improving the orderliness of multiple groups of lines after connection. The angle assembly can adjust the angle between these terminal blocks, effectively improving the connection requirements of different angles and directions between different groups of lines, and increasing the adaptability to complex wiring requirements.

[0006] Preferably, the clamping assembly includes an upper pressing block, a lower pressing block, and an extrusion block movably clamped on the wiring port. The upper pressing block and the lower pressing block are symmetrically arranged inclined-plane structures. The extrusion block is connected to the driving assembly and is provided with a "V"-shaped limiting groove. The limiting groove can slide along the inclined surfaces of the upper pressing block and the lower pressing block and make the upper pressing block and the lower pressing block move toward each other.

[0007] The driving assembly drives the extrusion block to slide along the length direction of the wiring port, and its limit groove squeezes the upper pressure block and the lower pressure block, and the upper pressure block and the lower pressure block are slidingly clamped at the wiring port. Therefore, the upper pressure block and the lower pressure block are only subjected to the longitudinal driving force converted from the lateral driving force applied by the extrusion block, so that the upper pressure block and the lower pressure block move toward each other. This process does not require the aid of other tools to tighten the wires inserted into the wiring port, effectively improving the wiring efficiency. Moreover, the contact area between the upper pressure block and the lower pressure block and the wires is large, and the wires are not easy to fall off, effectively improving the stability of the wiring.

[0008] Preferably, a shift hole is provided on the terminal seat, and a sliding groove is provided on the side of the extrusion block close to the shift hole. The driving assembly includes a sliding block slidably clamped in the sliding groove, and a pull rod slidably clamped in the shift hole. One end of the pull rod is connected to the sliding block, and the other end extends toward the outside of the terminal seat and is connected to a sliding button.

[0009] The sliding block, pull rod and slide button constitute the handle of the extrusion block extending to the outside of the terminal block. Pushing the handle can apply force to the extrusion block to drive the extrusion block, and the gear hole limits the range of movement of the pull rod, thereby limiting the range of movement of the extrusion block so that the upper pressure block and the lower pressure block can completely tighten the wire. The gear hole has gears of different distances. The gears cooperate with the sliding groove to enable the aforementioned handle to drive the extrusion block to be clamped in different gears, and leave a certain distance between the upper pressure block and the lower pressure block to adapt to wires of different thicknesses, thereby improving the adaptability of the terminal to different types of circuits.

[0010] Preferably, the reset assembly includes a plurality of guide shafts, an elastic member is sleeved on the guide shafts, the upper pressing block and the lower pressing block are slidably clamped on the plurality of guide shafts, and the elastic member is located between the upper pressing block and the lower pressing block.

[0011] The guide shaft can further ensure that the upper and lower pressing blocks are only subjected to the longitudinal driving force converted from the lateral driving force applied by the extrusion block, reduce the loss of the longitudinal force, and improve the smoothness of the movement of the upper and lower pressing blocks; the elastic member provides a certain degree of buffering for the upper and lower pressing blocks when they move toward each other, which is beneficial to improving the service life of the upper and lower pressing blocks. When a reverse driving force is applied to the extrusion block, the upper and lower pressing blocks themselves do not generate a reverse driving force, but rely on the elastic member to approach the inner wall of the wiring port to achieve reset, which is beneficial to ensure the normal wiring and improve wiring efficiency.

[0012] Preferably, the conductive component includes a conductive plate fixedly connected to the connecting seat, and a "Y"-shaped conductive sheet movably provided in the limiting groove, two ends of the "Y"-shaped conductive sheet are respectively connected to the upper pressure block and the lower pressure block, and the remaining end passes through the extrusion block and the terminal seat and is movably connected to the conductive plate.

[0013] The "Y"-shaped conductive sheet can be connected to the upper pressure block and the lower pressure block at the same time, and then connected to another "Y"-shaped conductive sheet through the conductive plate, which is beneficial to improving the conduction efficiency of the electrical connection. When the conductive end of the upper pressure block or the lower pressure block is damaged, the other conductive end can continue to be used to achieve electrical connection, which is beneficial to improving the stability and reliability of the electrical connection.

[0014] Preferably, the snap-fit ​​assembly includes a snap ring and a snap groove provided on the connecting seat, the snap ring and the snap groove are respectively located on two opposite outer sides of the connecting seat, and a buckle is provided at one end of the snap ring away from the connecting seat, and the buckle matches the buckle.

[0015] The clip and the connecting seat are independent of each other, which is convenient for production and processing and later maintenance, and can extend the distance between the clip and the connecting seat. After multiple clips are connected to the slots, a certain distance is left between the two terminals to avoid mutual influence; multiple clips match the slots, and the clips and slots are arranged on the two opposite outer surfaces of the connecting seat, which means that when multiple groups of lines need to be connected, multiple terminals can be connected into a terminal row through corresponding clips and slots. While meeting the connection of multiple groups of lines, these terminals can also be integrated together to improve neatness and aesthetics. When adjusting the number of terminals, multiple clips and slots can also be easily loaded and unloaded.

[0016] Preferably, the angle assembly includes a first chuck and a second chuck fixedly connected to the connecting seat, the first chuck is arranged in the retaining ring, and the second chuck is arranged in the retaining groove, and the first chuck and the second chuck are provided with matching concave-convex structures on the end faces away from the connecting seat, and the concave-convex structures are rotationally symmetrical along the axis of the first chuck or the second chuck.

[0017] The position setting of the first chuck and the second chuck is conducive to positioning their installation positions and improving installation efficiency. When multiple terminals are connected to form a terminal row through a clamping assembly, the first chuck and the second chuck of different terminals can also be normally relative to each other and function; when two terminals are connected, the first chuck of one and the second chuck of the other will abut each other, and the concave-convex structure on the corresponding end faces ensures that they will not easily rotate relative to each other, and the rotational symmetry of the concave-convex structure enables them to abut at different angles, that is, the connecting seats of two different terminals can be clamped together at different angles, effectively improving the connection requirements of different angles and directions between different groups of lines, and increasing adaptability to complex wiring requirements; due to the existence of the concave-convex structure, a certain amount of rotational force is required to separate the buckles and slots between different terminals, thereby changing the clamping angle, which is conducive to improving the stability and reliability of the connection and angle setting between different terminals.

[0018] Preferably, the concave-convex structure includes a first serrated surface provided on the first chuck, and a second serrated surface provided on the second chuck, and the first serrated surface and the second serrated surface can be staggered and clamped.

[0019] The concave-convex structure is composed of two matching serrated surfaces, the teeth on which are rotationally symmetrical around the axis of the first chuck or the second chuck, which can reduce the single angle adjustment range between different terminal blocks, making the angle adjustment more delicate, further improving the connection requirements for different angles and directions between different groups of lines, and increasing the adaptability to small-angle wiring requirements.

[0020] Preferably, the rotating clamping mechanism also includes a mounting assembly, which includes a first mounting plate and a second mounting plate connected to the connecting seat, the clamping ring is threadedly connected to the first mounting plate, and a limiting groove is provided on the second mounting plate, and the limiting groove cooperates with the connecting seat to form the clamping groove.

[0021] The connecting seat itself is not large in size, and the installation assembly can provide additional space and accurate positioning for the installation of the snap-on assembly and the angle assembly, increase the distance between different terminal blocks after connection, and avoid mutual influence; the threaded connection of the clamping ring is convenient for loading and unloading and subsequent maintenance on the one hand, and on the other hand, it does not need to be installed on the connecting seat, which is beneficial to improve the strength of the connecting seat. The same is true for the limit groove on the second mounting plate, and the overall structure of the connecting seat can also be maintained. Moreover, the clamping ring and the clamping groove can be replaced with different specifications and types according to the structural changes of the installation assembly, effectively improving the flexibility of the design.

[0022] Preferably, the first chuck and the second chuck are arranged on two opposite outer sides of the connecting seat along the same center line.

[0023] The first chuck and the second chuck are located along the same center line, and the clamping ring and the clamping groove are also located on the same center line. At this time, when different terminals are connected, the connection seats of each terminal are also located on the same center line, which can further improve the neatness and aesthetics and facilitate later maintenance.

[0024] Compared with the prior art, the beneficial effects of the present invention are:

[0025] The utility model adopts three parts, namely a connecting base and two terminal bases. The two terminal bases can be rotatably connected to the connecting base, so that the same circuit can be installed on the terminal block at different angles and directions and electrically connected; a clamping mechanism is adopted in the wiring port in the terminal block, and the clamping assembly is driven by the driving assembly to clamp the wire inserted into the wiring port, so that the wire is fastened in the wiring port. When the wire needs to be released, the reset assembly assists the driving assembly to make the clamping assembly loosen the wire. There is no need to use other tools to adjust the clamping mechanism, which is beneficial to improving the efficiency of wire loading and unloading; a clamping assembly is adopted to enable multiple wiring terminals to be arranged in parallel to form a wiring terminal row, and the number of wiring terminals can be adjusted as needed, which is beneficial to improving the adaptability to multiple groups of lines and improving the orderliness of multiple groups of lines after connection. Angle components are adopted to adjust the angles between these wiring terminals, effectively improving the connection requirements of different angles and directions between different groups of lines, and increasing the adaptability to complex wiring requirements.

In the description of this utility model, "plurality" means two or more, unless otherwise specifically defined.

[0036] In this embodiment, please refer to Figures 1 to 5 As shown, the utility model provides a modular terminal block with multi-angle adjustment, including a connecting base 100 with openings at both ends, terminal bases 200 are rotatably provided at both ends of the connecting base 100, a wiring port 210 is provided on the terminal base 200, and a clamping mechanism 300 for placing and clamping the wire is provided in the wiring port 210, the clamping mechanism 300 includes a clamping component 310, and a driving component 320 and a reset component 330 connected to the clamping component 310, a conductive component 400 is provided in the connecting base 100 and the terminal base 200, and the two clamping mechanisms 300 are electrically connected through the conductive component 400; a rotating clamping mechanism 500 is also provided on the connecting base 100, and the rotating clamping mechanism 500 includes a clamping component 510 and an angle component 520, the clamping component 510 is used to connect the two modular terminal blocks, and the angle component 520 is used to adjust the angle between the two modular terminal blocks.

[0037] As can be understood, the terminal block is divided into three parts, namely a connecting base 100 and two terminal bases 200. Both terminal bases 200 are rotatably connected to the connecting base 100 through a rotating shaft 110, so that the same circuit can be installed on the terminal block at different angles and directions and electrically connected; the clamping mechanism 300 in the wiring port 210 drives the clamping assembly 310 through the driving assembly 320 to clamp the wire inserted into the wiring port 210, so that the wire is fastened in the wiring port 210. When the wire needs to be released, the reset assembly 330 assists the driving assembly 320 to release the clamping assembly 310; when multiple groups of lines need to be connected, the snap-in assembly 510 on the terminal block can cooperate with the snap-in assembly 510 on other terminals to form a terminal block row with multiple parallel terminals, and the number of terminals can be adjusted as needed. The angle assembly 520 can adjust the angle between these terminals, so that multiple groups of lines can be installed on the terminal block at different angles and directions.

[0038] In this embodiment, please refer to Figure 1 、 3As shown in Figure 4, the clamping assembly 310 includes an upper pressing block 311, a lower pressing block 312, and an extrusion block 313 that are movably clamped on the wiring port 210. The upper pressing block 311 and the lower pressing block 312 are symmetrically arranged inclined-plane structures. The extrusion block 313 is connected to the driving assembly 320 and is provided with a "V"-shaped limiting groove 3131. The limiting groove 3131 can slide along the inclined surfaces of the upper pressing block 311 and the lower pressing block 312 and make the upper pressing block 311 and the lower pressing block 312 move toward each other.

[0039] The cam 313 is engaged with the cam 314 and the cam 315 is engaged with the cam 316. The cam 317 is engaged with the cam 318 and the cam 319. 2008-09-07 07:45:45 31100 31200 is engaged with the cam 319 and the cam 310 is engaged with the cam 319.

[0040] In addition, in some embodiments, matching serrated surfaces are provided on the opposite end faces of the upper pressing block 311 and the lower pressing block 312; or only the upper pressing block 311 or the lower pressing block 312 may be retained. In this case, the extrusion block 313 is also a bevel structure, and the bevel of the extrusion block 313 is opposite to the bevel of the upper pressing block 311 or the lower pressing block 312, converting the lateral movement of the extrusion block 313 into the longitudinal movement of the upper pressing block 311 or the lower pressing block 312.

[0041] A shift hole 220 is provided on the terminal seat 200, and a sliding groove 3132 is provided on the side of the extrusion block 313 close to the shift hole 220. The driving assembly 320 includes a sliding block 321 that is slidably clamped in the sliding groove 3132, and a pull rod 322 that is slidably clamped in the shift hole 220. One end of the pull rod 322 is connected to the sliding block 321, and the other end extends toward the outside of the terminal seat 200 and is connected to a sliding button 323.

[0042] It can be understood that the structure of the shift hole 220 is a long strip hole with multiple short strip holes connected on both sides. The pull rod 322 can slide into these short strip holes to adjust the moving distance of the extrusion block 313, and then adjust the distance between the upper pressing block 311 and the lower pressing block 312 to achieve the compression requirements of different types of wires.

[0043] In addition, in some embodiments, symmetrical shifting holes 220 are provided on opposite sides of the terminal seat 200. Correspondingly, symmetrical sliding grooves 3132 are also provided on opposite sides of the extrusion block 313, and the driving components 320 are also symmetrically arranged in two groups.

[0044] The reset assembly 330 includes a plurality of guide shafts, on which elastic members are sleeved. The upper pressing block 311 and the lower pressing block 312 are slidably clamped on the plurality of guide shafts, and the elastic member is located between the upper pressing block 311 and the lower pressing block 312 .

[0045] It can be understood that the guide shaft limits the sliding direction of the upper pressure block 311 and the lower pressure block 312 to a direction perpendicular to the movement of the extrusion block 313; the elastic member buffers the toward-toward movement of the upper pressure block 311 and the lower pressure block 312, and provides the upper pressure block 311 and the lower pressure block 312 with elastic force to move away from each other to achieve reset. The elastic member can be a compression spring, a disc spring, a wave spring, etc.

[0046] The conductive component 400 includes a conductive plate 410 fixedly connected to the connecting seat 100, and a "Y"-shaped conductive sheet 420 movably arranged in the limiting groove 3131, wherein two ends of the "Y"-shaped conductive sheet 420 are respectively connected to the upper pressing block 311 and the lower pressing block 312, and the remaining end passes through the extrusion block 313 and the terminal seat 200 and is movably connected to the conductive plate 410.

[0047] It can be understood that the "Y"-shaped conductive sheet 420 can be connected to the upper pressing block 311 and the lower pressing block 312 at the same time, and the extrusion block 313 is provided with a limiting hole 3133 that passes through the limiting groove 3131. One end of the "Y"-shaped conductive sheet 420 passes through the limiting hole 3133 and is movably connected to one end of the conductive plate 410. Specifically, the two ends of the conductive plate 410 are respectively connected to the two rotating shafts 110. The "Y"-shaped conductive sheet 420 is rotatably connected to the conductive plate 410, and the other "Y"-shaped conductive sheet 420 is rotatably connected to the conductive plate 410. 20 Similarly, the electrical connection between the two clamping components 310 is finally achieved; it should be noted that when the extrusion block 313 moves, the upper pressing block 311 and the lower pressing block 312 also move toward each other. At this time, the "V"-shaped part of the "Y"-shaped conductive sheet 420 connecting the upper pressing block 311 and the lower pressing block 312 will shrink, so that the extrusion block 313 can move along the "Y"-shaped conductive sheet 420 through the limiting hole 3133. When the "V"-shaped part is fully contracted, the thickness should be less than or equal to the thickness of the remaining end.

[0048] In addition, in some embodiments, the "Y"-shaped conductive sheet 420 can also be a single bent conductive sheet, wire, or other conductive medium, and can also be connected to the upper pressing block 311 or the lower pressing block 312 at the same time, and only the upper pressing block 311 or the lower pressing block 312 is connected to the conductive plate 410.

[0049] In this embodiment, please refer to Figure 1 、 2 As shown in Figure 5, the snap-fit ​​assembly 510 includes a snap ring 511 and a snap groove 513 provided on the connecting base 100. The snap ring 511 and the snap groove 513 are respectively located on two opposite outer sides of the connecting base 100. A snap buckle 512 is provided at one end of the snap ring 511 away from the connecting base 100, and the snap buckle 512 matches the snap groove 513.

[0050] It can be understood that the snap ring 511 and the connecting base 100 are independent of each other and are connected by threaded fitting. The snap ring 511 is provided with an external thread; the snap ring 511 and the slot 513 are respectively arranged on the two opposite outer surfaces of the connecting base 100, one end of the clip 512 is connected to the snap ring 511, and the other end extends toward the outer side of the connecting base 100 along the axial direction of the snap ring 511, and the end is provided with a convex portion extending radially along the snap ring 511, and the slot 513 is a groove with a stepped structure and an annular groove matching the convex portion is provided inside. Multiple terminal blocks can be connected into a terminal row through corresponding snaps 512 and slots 513.

[0051] The angle assembly 520 includes a first chuck 521 and a second chuck 522 fixedly connected to the connecting seat 100. The first chuck 521 is arranged in the retaining ring 511, and the second chuck 522 is arranged in the retaining groove 513. The first chuck 521 and the second chuck 522 are provided with matching concave-convex structures on the end faces away from the connecting seat 100, and the concave-convex structures are rotationally symmetrical along the axis of the first chuck 521 or the second chuck 522.

[0052] It can be understood that the fixed connection is a bolt-fit connection; the first chuck 521 is located at the center of the clamping ring 511, and the second chuck 522 is located at the center of the slot 513; when the two terminals are connected together due to the clamping assembly 510, the first chuck 521 of one terminal and the second chuck 522 of the other terminal will abut against each other, and the concave-convex structure on their corresponding end faces is similar to a clutch structure, which can ensure that the first chuck 521 and the second chuck 522 will not easily rotate relative to each other, and the rotational symmetry of the concave-convex structure can make the first chuck 521 and the second chuck 522 abut at different angles, that is, the connecting bases 100 of two different terminals can be clamped together at different angles; after the different terminals are clamped, due to the existence of the concave-convex structure, a certain amount of rotational force is required to separate the buckle 512 and the slot 513 between the different terminals, thereby changing the clamping angle.

[0053] The concave-convex structure includes a first serrated surface 5211 provided on the first chuck 521 and a second serrated surface 5221 provided on the second chuck 522 . The first serrated surface 5211 and the second serrated surface 5221 can be staggered and engaged with each other.

[0054] It can be understood that the structures of the first chuck 521 and the second chuck 522 are similar to face gears and can mesh with each other to achieve small angle adjustment between the connection bases 100 of different terminal blocks.

[0055] In addition, in some embodiments, a plurality of protrusions are provided on the end face of the first chuck 521, and the plurality of protrusions are rotationally symmetrical along the axis of the first chuck 521. A groove matching the plurality of protrusions is provided on the end face of the second chuck 522. The first chuck 521 and the second chuck 522 are staggered and connected through these protrusions and grooves to achieve small angle adjustment.

[0056] The rotating clamping mechanism 500 also includes an installation assembly 530, which includes a first mounting plate 531 and a second mounting plate 532 connected to the connecting seat 100. The retaining ring 511 is threadedly connected to the first mounting plate 531, and a limiting groove 3131 is provided on the second mounting plate 532. The limiting groove 3131 cooperates with the connecting seat 100 to form a clamping groove 513.

[0057] It can be understood that the first mounting plate 531 and the second mounting plate 532 are detachably connected to the connecting seat 100, such as a threaded connection; the first mounting plate 531 is provided with a threaded hole for threaded engagement with the retaining ring 511, and the second mounting plate 532 is provided with a stepped hole serving as the wall of the limiting groove 3131, and the connecting seat 100 is used as the bottom of the limiting groove 3131.

[0058] In addition, in some embodiments, the limiting groove 3131 is provided on the second mounting plate 532; or a through hole (not shown) is provided on the second mounting plate 532 and a groove is provided on the connecting seat 100, and the through hole and the groove cooperate to form the limiting groove 3131.

[0059] The first chuck 521 and the second chuck 522 are disposed along the same center line at two opposite outer sides of the connecting base 100 .

[0060] It can be understood that this design enables the clamping ring 511 and the clamping groove 513 to be located on the same center line. When connecting different wiring terminals, the connection bases 100 of each wiring terminal are also located on the same center line, so that they are arranged neatly.

[0061] Additionally, in some embodiments, the first chuck 521 and the second chuck 522 may not be on the same center line.

[0062] The specific application process of this utility model is as follows:

[0063] In the initial state, the upper pressing block 311 and the lower pressing block 312 are away from each other, and the extrusion block is located at one end of each lower pressing block 312 away from the upper pressing block 311;

[0064] Wiring a single group of lines: put one side of the wire into the wiring port 210, apply force to the slide button 323 of the drive assembly 320, and drive the extrusion block 313 to move along the length direction of the wiring port 210 through the pull rod 322 and the sliding block 321. At this time, the extrusion block 313 is subjected to a lateral driving force, and the limiting groove 3131 of the extrusion block 313 simultaneously squeezes the inclined surfaces of the upper pressing block 311 and the lower pressing block 312. The upper pressing block 311 and the lower pressing block 312 move toward each other along the axial direction of the guide shaft and are buffered by the elastic member. At this time, the upper pressing block 311 and the lower pressing block 312 are subjected to the longitudinal driving force converted from the lateral driving force applied by the extrusion block 313, and press the wire tightly; pull the pull rod When the cam 322 is inserted into the appropriate position on the stop hole 220, the movement of the upper pressing block 311 of the extrusion block 313 and the lower pressing block 312 is restricted. The access direction of the wire will automatically adjust the angle between the terminal block 200 and the connecting block 100. The same is true for the wire on the other side. When removing the wire, the position of the moving pull rod 322 on the stop hole 220 causes the extrusion block 313 to move in the opposite direction under the opposite lateral driving force. At this time, the upper pressing block 311 and the lower pressing block 312 are not subjected to the pressure of the extrusion block 313, but are moved in opposite directions by the elastic force of the elastic member, so that the upper pressing block 311 and the lower pressing block 312 are separated from each other, and the wire can be removed. The same is true for the wire on the other side.

[0065] Wiring multiple groups of lines: Use multiple wiring terminals to perform the above operation on each group of wires, adjust the angle between any two wiring terminals and clamp them through the buckle 512 and the slot 513 of the clamping assembly 510. At this time, the first clamp 521 of one of the wiring terminals and the second clamp 522 of the other wiring terminal are engaged. When it is necessary to adjust the angle between two adjacent wiring terminals, a short rotational force is applied to each connecting seat 100 to cause a single rotation and re-engagement between the first clamp 521 and the second clamp 522. The buckle 512 and the slot 513 are first disengaged and then clamped. The rotational force is applied multiple times until the angle between the two adjacent wiring terminals meets the requirements. When it is necessary to disassemble the two adjacent wiring terminals, the wiring terminals can be pulled apart when the buckle 512 and the slot 513 are disengaged from each other.
