Description

Technical Field

[0001] This invention relates to the field of terminal blocks, specifically a terminal block with multi-wire connection capability. Background Technology

[0002] Terminal blocks are accessories used to achieve electrical connections. In industry, they are classified as connectors. With the increasing level of industrial automation and the increasingly stringent and precise requirements of industrial control, the use of terminal blocks has gradually increased. With the development of the electronics industry, the application range of terminal blocks has expanded, and the types have also increased. In addition to PCB board terminals, the most widely used are hardware terminals, nut terminals, and spring terminals, etc. Terminal blocks are used to facilitate the connection of wires. They are actually a metal strip sealed in insulating plastic. After connecting several sets of wires through terminal blocks, they can be disconnected at any time without soldering or winding them together, which is more convenient and quick.

[0003] Commonly available terminal blocks on the market are usually secured with nuts when connecting wires. This method is not very effective and the wires are easily damaged when the nuts are turned. The connection mechanism is also easily damaged by collisions or friction. Therefore, we propose a terminal block with multi-wire connection capability. Summary of the Invention

[0004] The purpose of this invention is to provide a terminal block with multi-wire connection capability to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a terminal block with multi-wire connection effect, including a base, a connection groove is provided at the upper end of the base near the middle position, a partition is provided at the bottom end of the connection groove near the middle position, a plurality of boundary connection mechanisms are provided at the bottom end of the connection groove and on both sides of the partition, and a protective mechanism is provided at the upper end of the base.

[0006] As a further embodiment of the present invention: the wiring mechanism includes a base plate, a terminal block is provided at the upper end of the base plate, a slot is provided on the outer side wall of the terminal block near the base plate, four sets of vertical slots are provided at equal intervals on the outer side wall of the terminal block, and a nut is provided at the top of the terminal block.

[0007] As a further embodiment of the present invention: a fixing plate is provided on the terminal block, and an arc-shaped groove is opened at the bottom end of the fixing plate near the middle position. A fixing plate is provided on the surface of the terminal block and above the fixing plate, and four sets of sliding plates are equidistantly arranged on the inner side wall of the fixing plate.

[0008] As a further embodiment of the present invention: a threaded groove that fits with the nut is provided on the outer wall of the terminal block above the slot, and a spring is wound around the surface of the terminal block between the fixing plate one and the fixing plate two, and the two ends of the spring are respectively fixed to the surfaces of the fixing plate one and the fixing plate two.

[0009] As a further embodiment of the present invention: the second fixing plate slides up and down along the terminal block via a sliding plate and a vertical groove, and the first fixing plate slides up and down along the terminal block via a spring and the second fixing plate.

[0010] As a further embodiment of the present invention: the protective mechanism includes a protective plate, a groove is provided at the upper end of the protective plate near one side, a horizontal groove is provided on the inner side wall of the groove, a fixing groove is provided at the upper end of the protective plate near the other side, and a clamping plate is provided on the inner side wall of the fixing groove.

[0011] As a further embodiment of the present invention: a vertical plate is provided at the upper end of the base and near one side, and a rotating shaft that fits into the horizontal groove is provided on both sides of the vertical plate. Two sets of sliding grooves are provided at the upper end of the base near the other side, and a slider is provided inside the sliding groove. A push plate is provided at the upper end of the slider, a positioning plate is provided at the upper end of the push plate, and several sets of friction plates are provided at the upper end of the positioning plate.

[0012] As a further embodiment of the present invention: a sliding rod is provided between the inner sidewalls of the slide groove, and a second spring is wound around the surface of the sliding rod. The slider slides left and right along the slide groove through the second spring and the sliding rod. The positioning plate is movably set at the upper end of the card plate through the push plate. The protective plate is movably set with the base through the groove, the vertical plate and the rotating shaft and the horizontal groove.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows: This multi-wire connection terminal allows the wire to pass through the slot and then be wound around the outer wall surface of the terminal. After that, the nut is rotated counterclockwise, and the nut pushes the second fixing plate and the first fixing plate downward along the terminal through the threaded groove. When the arc-shaped groove at the bottom of the first fixing plate engages with the wire, the nut continues to apply a downward pushing force to the second fixing plate. At this time, the second fixing plate moves along the vertical groove towards the first fixing plate via the sliding plate. As the distance between the second fixing plate and the first fixing plate gradually decreases, the first spring is compressed. The compressed first spring applies a downward pushing force to the first fixing plate, making it press against the outer wall of the wire and limit its position, thereby clamping the wire well between the first fixing plate and the base plate. This makes it easier for workers to stably set the wire on the terminal to prevent it from falling off and can also prevent wear on the wire.

[0014] This multi-wire connection terminal block applies a leftward push to the push plate via a positioning plate. The push plate then slides leftward along the slide groove via a slider and a sliding rod, moving the positioning plate from the upper end of the clamping plate into the fixed slot. A friction plate increases the friction between the worker's hand and the positioning plate, facilitating its movement. A rotating shaft then pushes the protective plate rightward along the horizontal groove, ensuring the inner wall of the groove is flush with the shaft. A vertical plate and rotating shaft, along with a groove, rotate the protective plate to a position perpendicular to the upper surface of the base. The worker can then wind wires onto the connection mechanism. After the wires are connected, the rotating shaft and vertical plate, along with the groove, rotate the protective plate to the upper end of the base, above the connection slot. A spring then applies a rightward push to the slider, causing it to move rightward along the slide groove, moving the positioning plate from the fixed slot to the upper end of the clamping plate. This limits the protective plate's position on the upper surface of the base, effectively shielding and protecting the connection mechanism inside the connection slot from damage due to collisions or friction.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0023] In the description of this invention, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this invention.

[0024] Example 1

[0025] Please see Figure 1-3 The present invention provides a technical solution: a terminal block with multi-line connection effect, including a base 1, a connection groove 4 is provided at the upper end of the base 1 near the middle position, a partition 5 is provided at the bottom end of the connection groove 4 near the middle position, a number of boundary connection mechanisms 6 are provided at the bottom end of the connection groove 4 and on both sides of the partition 5, and a protective mechanism 16 is provided at the upper end of the base 1.

[0026] Please see Figure 2-3 The wiring mechanism 6 includes a base plate 7, a terminal block 8 is provided on the upper end of the base plate 7, a slot 9 is provided on the outer wall of the terminal block 8 near the base plate 7, four sets of vertical slots 12 are provided at equal intervals on the outer wall of the terminal block 8, and a nut 15 is provided on the top of the terminal block 8.

[0027] A fixing plate 10 is provided on the terminal block 8. An arc-shaped groove 11 is opened at the bottom of the fixing plate 10 near the middle position. A fixing plate 2 13 is provided on the surface of the terminal block 8 and above the fixing plate 10. Four sets of sliding plates 14 are equidistantly arranged on the inner side wall of the fixing plate 2 13.

[0028] A threaded groove that fits with the nut 15 is provided on the outer wall of the terminal block 8 above the slot 9. A spring is wound around the surface of the terminal block 8 between the first fixing plate 10 and the second fixing plate 13, and the two ends of the spring are fixed to the surfaces of the first fixing plate 10 and the second fixing plate 13, respectively.

[0029] The second fixing plate 13 slides up and down along the terminal post 8 via the sliding plate 14 and the vertical groove 12, while the first fixing plate 10 slides up and down along the terminal post 8 via the spring and the second fixing plate 13.

[0030] In use, the operator applies a leftward pushing force to the push plate 26 via the positioning plate 27. The push plate 26 then slides to the left along the slide groove 24 via the slider 25 and sliding rod, moving the positioning plate 27 from the upper end of the clamping plate 23 into the fixing groove 22. The friction plate 28 increases the friction between the operator's hand and the positioning plate 27, facilitating its movement. Then, the protective plate 19 is pushed to the right along the horizontal groove 21 via the rotating shaft 3, ensuring the inner wall of the horizontal groove 21 is tightly against the rotating shaft 3. Next, the protective plate 19 is rotated to a position perpendicular to the upper surface of the base 1 via the vertical plate 2 and the rotating shaft 3 in conjunction with the groove 20. The operator then passes the wire through the slot 9 and wraps it around the outer wall of the terminal 8. Finally, the nut 15 is rotated counterclockwise, pushing the fixing plate 13 and the fixing plate 10 along the terminal 8 via the threaded groove. As the device moves downward, once the arc-shaped groove 11 at the bottom of the first fixing plate 10 engages with the wire, the second fixing plate 13 continues to be pushed downward by the nut 15. At this time, the second fixing plate 13 moves along the vertical groove 12 towards the first fixing plate 10 via the slide plate 14. As the distance between the second fixing plate 13 and the first fixing plate 10 gradually decreases, the first spring is compressed. The compressed spring exerts a downward force on the first fixing plate 10, causing it to press tightly against the outer wall of the wire and limit its position. This effectively clamps the wire between the first fixing plate 10 and the base plate 7, making it easier for workers to stably place the wire on the terminal block 8 and prevent it from falling off. At this time, workers can connect multiple sets of wires to the terminal block as needed. Meanwhile, the partition 5 can separate the two sets of wiring mechanisms 6 to prevent the wires wrapped around the terminal block 8 from contacting each other.

[0031] Example 2

[0032] Please see Figure 4-6 The present invention provides a technical solution: a terminal block with multi-line connection effect, including a base 1, a connection groove 4 is provided at the upper end of the base 1 near the middle position, a partition 5 is provided at the bottom end of the connection groove 4 near the middle position, a number of boundary connection mechanisms 6 are provided at the bottom end of the connection groove 4 and on both sides of the partition 5, and a protective mechanism 16 is provided at the upper end of the base 1.

[0033] Please see Figure 5-6 The protective mechanism 16 includes a protective plate 19. A groove 20 is provided on the upper end of the protective plate 19 near one side. A horizontal groove 21 is provided on the inner side wall of the groove 20. A fixing groove 22 is provided on the upper end of the protective plate 19 near the other side. A clamping plate 23 is provided on the inner side wall of the fixing groove 22.

[0034] A vertical plate 2 is provided on the upper part of the base 1 and near one side. A rotating shaft 3 that fits into the horizontal groove 21 is provided on both sides of the vertical plate 2. Two sets of sliding grooves 24 are provided on the upper part of the base 1 near the other side. A slider 25 is provided inside the sliding groove 24. A push plate 26 is provided on the upper part of the slider 25. A positioning plate 27 is provided on the upper part of the push plate 26. Several sets of friction plates 28 are provided on the upper part of the positioning plate 27.

[0035] A sliding rod is provided between the inner sidewalls of the slide groove 24, and a second spring is wound around the surface of the sliding rod. The slider 25 slides left and right along the slide groove 24 through the second spring and the sliding rod. The positioning plate 27 is movably set at the upper end of the clamping plate 23 through the push plate 26. The protective plate 19 is movably set with the base 1 through the groove 20, the vertical plate 2 and the rotating shaft 3 in conjunction with the horizontal groove 21.

[0036] Specifically, after the wires are connected, the protective plate 19 is rotated to the upper end of the base 1 and positioned above the connecting groove 4 by the rotating shaft 3 and the vertical plate 2 in conjunction with the groove 20. Then, the spring 2 applies a rightward pushing force to the slider 25, causing the slider 25 to push the push plate 26 to the right along the sliding groove 24, thereby moving the positioning plate 27 from the fixing groove 22 to the upper end of the clamping plate 23. This limits the protective plate 19 so that it is well positioned on the upper surface of the base 1, which can effectively shield and protect the wiring mechanism 6 located inside the connecting groove 4, preventing damage to the wiring mechanism 6 caused by collision or friction.

[0037] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
