Technical Field

[0001] This utility model relates to the field of terminal block technology, and in particular to a rail-mounted terminal block. Background Technology

[0002] Chinese Patent CN218783237U discloses a rail-mounted terminal block, comprising at least one terminal block component arranged sequentially and interlocking with each other. Each terminal block component includes a housing and conductive elements. A set of connection ports is provided at the upper end of the housing. The conductive elements include mutually clamping elastic clips and metal clips. The metal clips within the connection ports are interconnected via connectors. A mounting post is provided within each connection port. The elastic clips are mounted on the mounting post and rotate relative to it. An operating port is provided on one side of each connection port, and an operating block is provided within each operating port. The lower end of the operating block corresponds to the movable end of the elastic clip. The other end of the elastic clip serves as a fixed end that abuts against the connecting housing. A step protrudes outward from the side wall of the metal clip corresponding to the elastic clip. The movable end of the metal clip is located below the step and abuts against and clamps against the step. Two short-circuit channels are arranged side by side on the housing. The short-circuit channels connect to the connector, and short-circuit holes are respectively opened on the connector corresponding to the short-circuit channel positions. A grounding hole is also opened on the connector. A grounding plate is also provided inside the housing of the outermost terminal piece. A pin is provided on the grounding plate and is inserted into the connector. The grounding plate extends with a grounding foot, which protrudes from the track clamping groove.

[0003] However, the above-mentioned terminal block has the following disadvantages: the pins of the terminal block are fixedly inserted into the shorting hole to connect the grounding plate and the connector. However, the connection method of plugging and fixing is not stable enough. It is easy for the connection point between the pin and the shorting hole to loosen due to shaking, which may cause the grounding plate and the connector to detach from each other. It needs to be improved. Utility Model Content

[0004] The purpose of this utility model is to provide a rail-mounted terminal block, which improves the stability of the connection between the grounding plate and the current-carrying plate, and enhances the convenience and efficiency of the assembly of this utility model.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a rail-mounted terminal block, comprising an insulating plastic shell, wherein the insulating plastic shell is provided with a metal clamp, a current-carrying plate and a grounding plate, the metal clamp is electrically connected to the grounding plate through the current-carrying plate, the grounding plate has a pin connection portion, the current-carrying plate has a mounting hole corresponding to the pin connection portion, and the pin connection portion is riveted into the mounting hole, so that the current-carrying plate and the grounding plate are fixedly connected.

[0006] By adopting the above technical solution, during assembly, the pin connection of the grounding plate is first riveted to the corresponding mounting hole on the current-carrying plate, so that the grounding plate and the current-carrying plate are fixedly connected. Then, the metal clamp is connected to the side of the current-carrying plate. After that, the current-carrying plate with the metal clamp and the grounding plate is installed as a whole onto the insulating plastic shell. The grounding plate and the current-carrying plate of this utility model are fixed by riveting, which can improve the stability of the connection between the two, and at the same time improve the convenience and efficiency of the assembly of this utility model.

[0007] A further feature of this invention is that the insulating plastic shell has a first mounting groove, a second mounting groove, and a third mounting groove. The second mounting groove is laterally opened on the insulating plastic shell. The first mounting groove is connected to the third mounting groove through the second mounting groove. The metal clamp is slidably disposed in the first mounting groove. The current-carrying plate is installed in the second mounting groove. The grounding plate is embedded in the third mounting groove.

[0008] A further feature of this invention is that: two third mounting slots are provided, and the two third mounting slots are connected and disposed on both sides of the second mounting slot; the metal clamp is provided with a wiring hole; the end of the current-carrying plate passes through the wiring hole; and the outer wall of the insulating plastic shell is provided with a through hole that connects to the first mounting slot.

[0009] By adopting the above technical solution, the wire can be passed through the wire hole into the wiring hole of the metal clamp, and the wire end can be pressed into the wiring hole of the metal clamp by fasteners.

[0010] A further feature of this invention is that the bottom of the metal clamp extends downward to form a wire-blocking portion, and the insulating plastic shell has an avoidance groove that communicates with the first mounting groove. When the metal clamp slides in the first mounting groove, the wire-blocking portion avoids and cooperates with the avoidance groove.

[0011] By adopting the above technical solution, when the wire is installed, the metal clamp may be located at the top of the first mounting groove. At this time, there is a gap between the metal clamp and the bottom of the first mounting groove, and the wire blocking part can prevent the wire end from being accidentally installed into the gap.

[0013] By adopting the above technical solution, the triangularly distributed positioning ribs, in conjunction with the corresponding positioning grooves, can ensure a stable connection between the grounding plate and the insulating plastic shell, thereby improving the anti-sway performance of the grounding plate installed in the third mounting groove. At the same time, since the current-carrying plate and the grounding plate are connected by riveting, when the anti-sway performance of the grounding plate is improved, the current-carrying plate can also be more firmly installed in the corresponding second mounting groove.

[0014] A further feature of this invention is that at least one of the positioning grooves includes a horizontal section and a vertical section, the end of the vertical section away from the horizontal section extends and penetrates the bottom of the grounding plate, and the insulating plastic shell is provided with positioning ribs corresponding to both the horizontal section and the vertical section.

[0015] By adopting the above technical solution, the positioning ribs arranged in multiple locations correspond to the horizontal and vertical sections of the positioning groove, which can further improve the connection between the grounding plate and the insulating plastic shell.

[0016] A further feature of this invention is that the grounding plate includes a first grounding portion, the bottom surface of the first grounding portion is a plane, and the bottom surface of the first grounding portion is flush with the edge of the corresponding position of the insulating plastic shell.

[0017] By adopting the above technical solution, the bottom surface of the first grounding part, which is set in a plane, can increase the contact area between the first grounding part and the track.

[0018] A further feature of this invention is that the insulating plastic shell has a guide rib below the first grounding portion, the guide rib extends along the thickness direction of the insulating plastic shell, and the lower end face of the guide rib is an arc-shaped surface.

[0019] By adopting the above technical solution, the guide ribs, in conjunction with the guide grooves corresponding to the track, can prevent the terminal block of this utility model from swinging left and right when it slides on the track. The guide ribs with inverted conical cross sections can reduce the contact area between them and the track, thereby improving the smoothness of the terminal block of this utility model sliding on the track.

[0020] A further feature of this invention is that the grounding plate includes a second grounding portion, and the bottom of the insulating plastic shell is provided with anti-detachment claws on both sides of the first grounding portion, and the end of the second grounding portion is bent and extends to the anti-detachment claws.

[0021] By adopting the above technical solution, the anti-detachment claw can be used to clamp the side of the track to prevent the wiring terminal from detaching from the track. At the same time, the end of the first grounding part is bent and extended on the anti-detachment claw, which can increase the number of contact points between the grounding plate and the track.

[0022] A further feature of this invention is that: a first fixing hole is symmetrically provided on the top of the insulating plastic shell near the two side edges, and a second fixing hole is symmetrically provided on both sides of the pin connection portion of the insulating plastic shell.

[0023] By adopting the above technical solution, the first fixing hole and the second fixing hole are used to quickly assemble the protective shell onto the insulating plastic shell, thereby protecting the electrical components on the insulating plastic shell from water and dust.

[0024] In summary, this utility model has the following beneficial effects: The grounding plate is riveted to the mounting hole of the current-carrying plate, thus fixing the grounding plate and the current-carrying plate together. Then, a metal clip is connected to the side of the current-carrying plate. Finally, the current-carrying plate with the metal clip and the grounding plate is installed onto the insulating plastic shell. The grounding plate and the current-carrying plate are fixed by riveting, which can improve the stability of the connection between the two, and also improve the convenience and efficiency of the assembly of this utility model.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings.

[0030] A type of rail-mounted terminal block, such as Figures 1-3As shown, the device includes an insulating plastic shell 1, on which a metal clip 2, a current-carrying plate 3, and a grounding plate 4 are provided. The metal clip 2 is electrically connected to the grounding plate 4 through the current-carrying plate 3. The grounding plate 4 has a pin connection part 41. The current-carrying plate 3 has a mounting hole 31 corresponding to the pin connection part 41. The pin connection part 41 is riveted into the mounting hole 31, so that the current-carrying plate 3 and the grounding plate 4 are fixedly connected. The insulating plastic shell 1 has a plurality of positioning protrusions 16, which are triangularly distributed. The grounding plate 4 has a positioning groove 40 corresponding to the positioning protrusions 16. The positioning protrusions 16 and the corresponding positioning grooves 40 are positioned and matched. The triangularly distributed positioning protrusions 16, in conjunction with the corresponding positioning grooves 40, can ensure a stable connection between the grounding plate 4 and the insulating plastic shell 1, thereby improving the anti-sway performance of the grounding plate 4 when installed in the third mounting groove 13. At the same time, since the current-carrying plate 3 and the grounding plate 4 are connected by riveting, when the anti-sway performance of the grounding plate 4 is improved... When the current-carrying plate 3 is high, it can be more firmly installed in the corresponding second mounting slot 12; at least one positioning slot 40 includes a horizontal section 401 and a vertical section 402. The end of the vertical section 402 away from the horizontal section 401 extends and penetrates the bottom of the grounding plate 4. The insulating plastic shell 1 is provided with positioning ribs 16 corresponding to the horizontal section 401 and the vertical section 402. The multiple positioning ribs 16 are positioned corresponding to the horizontal section 401 and the vertical section 402 of the positioning slot 40, which can further improve the connection between the grounding plate 4 and the insulating plastic shell 1; the top of the insulating plastic shell 1 is symmetrically provided with first fixing holes 101 near the two side edges. The insulating plastic shell 1 is symmetrically provided with second fixing holes 102 on both sides of the pin connection part 41. The first fixing holes 101 and the second fixing holes 102 are used to quickly assemble the protective shell onto the insulating plastic shell 1, so as to protect the electrical components on the insulating plastic shell 1 from water and dust.

[0031] like Figures 1-2As shown, the insulating plastic shell 1 has a first mounting groove 11, a second mounting groove 12, and a third mounting groove 13. The second mounting groove 12 is horizontally formed on the insulating plastic shell 1. The first mounting groove 11 communicates with the third mounting groove 13 through the second mounting groove 12. The metal clamp 2 is slidably disposed in the first mounting groove 11. The current-carrying plate 3 is installed in the second mounting groove 12, and the grounding plate 4 is embedded in the third mounting groove 13. There are two third mounting grooves 13, which are connected and disposed on both sides of the second mounting groove 12. The metal clamp 2 has a wiring hole 21, and the end of the current-carrying plate 3 passes through the wiring hole 21. The outer wall of the insulating plastic shell 1 has a connection to the first mounting groove 11. The wire through hole 14 allows the wire to pass through the wire through the wire through hole 14 and into the wiring hole 21 of the metal clamp 2, and the wire end is pressed into the wiring hole 21 of the metal clamp 2 by fasteners; the bottom of the metal clamp 2 extends downward with a wire blocking part 22, and the insulating plastic shell 1 has a relief groove 15 that communicates with the first mounting groove 11. When the metal clamp 2 slides in the first mounting groove 11, the wire blocking part 22 and the relief groove 15 cooperate with each other. When the wire is installed, the metal clamp 2 may be located at the top of the first mounting groove 11. At this time, there is a gap between the metal clamp 2 and the bottom of the first mounting groove 11. The wire blocking part 22 can prevent the wire end from being accidentally installed into the gap.

[0032] like Figures 1-3 As shown, the grounding plate 4 includes a first grounding portion 42. The bottom surface of the first grounding portion 42 is flat and flush with the edge of the corresponding position of the insulating plastic shell 1. The flat bottom surface of the first grounding portion 42 can increase the contact area between the first grounding portion 42 and the track. The insulating plastic shell 1 has a guide rib 17 below the first grounding portion 42. The guide rib 17 extends along the thickness direction of the insulating plastic shell 1, and the lower end surface of the guide rib 17 is arc-shaped. The guide rib 17 cooperates with the guide groove corresponding to the track to prevent the terminal block of this utility model from swaying left and right when it slides on the track. In motion, the guide rib 17 with an inverted conical cross section can reduce its contact area with the track, thereby improving the smoothness of the terminal block sliding on the track. The grounding plate 4 includes a second grounding part 43. The bottom of the insulating plastic shell 1 is provided with anti-detachment claws 18 on both sides of the first grounding part 42. The end of the second grounding part 43 is bent and extends to the anti-detachment claws 18. The anti-detachment claws 18 can be used to clamp the side of the track to prevent the terminal block from detaching from the track. At the same time, the end of the first grounding part 42 is bent and extends to the anti-detachment claws 18, which can increase the number of contact points between the grounding plate 4 and the track.

[0033] The basic working principle of this utility model is as follows: During assembly, the pin connection part 41 of the grounding piece 4 is first riveted to the corresponding mounting hole 31 on the current-carrying piece 3, so that the grounding piece 4 and the current-carrying piece 3 are fixedly connected to form an integral part. Then, the metal clamp 2 is connected to the side of the current-carrying piece 3. After that, the current-carrying piece 3 with the metal clamp 2 and the grounding piece 4 installed is installed as a whole onto the insulating plastic shell 1. The grounding piece 4 and the current-carrying piece 3 of this utility model are fixed by riveting, which can improve the stability of the connection between the two, and at the same time improve the convenience and efficiency of the assembly of this utility model.

[0034] The above description is only a preferred embodiment of the present utility model. Therefore, all equivalent changes or modifications made to the structure, features and principles described in the claims of the present utility model patent application are included in the scope of the present utility model patent application.
