Description

Technical Field

[0001] This utility model relates to the technical field of power distribution equipment, and in particular to a power distribution module connection accessory. Background Technology

[0002] A distribution box is a power distribution box used to rationally distribute electrical energy, facilitate circuit opening and closing operations, provide a high level of safety protection, and visually display the circuit's continuity status. It is a low-voltage distribution box constructed by assembling switching equipment, measuring instruments, protective electrical devices, and auxiliary equipment in a closed or panel-enclosed cabinet or panel according to electrical wiring requirements. During normal operation, the circuit can be connected or disconnected using manual or automatic switches. In case of faults or abnormal operation, protective electrical devices will disconnect the circuit or trigger an alarm. Measuring instruments can display various operating parameters, allow adjustment of certain parameters, and provide alerts or signals for deviations from normal operating conditions.

[0003] Existing distribution boxes basically consist of a box body, a panel, and a main body. The box body needs to be pre-embedded in the wall during use, so it must have good corrosion resistance. The panel consists of a panel frame and a cover plate, and an observation window is opened on the panel. The main body includes a main power interrupter and multiple branch power interrupters arranged side by side, as well as neutral wire junction components and ground wire junction components. Multiple branch power interrupters can be installed according to the power distribution in the building. The neutral wire and ground wire junction modules need to be electrically connected to both the main power interrupter and the branch power interrupters.

[0004] The current installation method for distribution boxes involves first installing the box body inside the wall, and then installing the main body after the building is constructed. When installing the main body, the main power breaker and the branch power breaker are usually placed side by side and fixed with their respective circuits installed. Then, the wires are fixed between the main power breaker and the branch power breaker with screws. When connecting the wires, depending on the structure of the main power breaker and the branch power breaker, it may be necessary to remove and install the covers on the connection points of the main power breaker and the branch power breaker, which increases the difficulty of the connection. After the wires are connected, they are laid horizontally between the main power breaker and the branch power breaker, and the wires are prone to being pulled or broken in case of accidental contact, which affects the stability of the connection between the main power breaker and the branch power breaker, and thus affects the safe use of electricity in the distribution box. Utility Model Content

[0005] The purpose of this utility model is to provide a power distribution module connection accessory that solves the connection stability problem that occurs when connecting the main power-off protector and the branch power-off protector with wires and screws, improves the connection stability between the main power-off protector and the branch power-off protector, and thus improves the electrical safety performance of the distribution box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a power distribution module connection accessory, including a housing and a cover plate, wherein the housing is disposed on one side of the cover plate and forms an installation cavity with the housing, the housing is provided with a wire adapter assembly located in the installation cavity, one end of the wire adapter assembly is provided with a first plug-in assembly embedded in the housing, the cover plate is provided with a second plug-in assembly, the second plug-in assembly is connected to the other end of the wire adapter assembly, the first plug-in assembly is electrically connected to the main power failure protector, and the second plug-in assembly is electrically connected to the branch power failure protector.

[0007] After adopting the above technical solution, this utility model has the following advantages: When connecting the main power-off protector and the branch power-off protector, the connecting accessory is placed between the main power-off protector and the branch power-off protector. The first plug-in component is connected to the main power-off protector on one side, and the other end is connected to the branch power-off protector on the other side through the second plug-in component. The middle part is connected through the wire adapter component, thus completing the electrical connection between the main power-off protector and the branch power-off protector. During connection, the first plug-in component and the second plug-in component are connected, and the plug-in connection improves the stability of the connection between the connecting accessory and the branch power-off protector and the main power-off protector. Compared with the existing connection through wires and screws, the connection is more stable, reducing the possibility of accidental damage to the distribution box and the need for more frequent maintenance. In addition, when connecting through the connecting accessory, the messy appearance of the wire crossbar is avoided, and the possibility of accidental wire connection leading to wire pulling or breakage is avoided. The adjacent power distribution modules are connected by connecting accessories formed by the housing, cover plate, wire adapter assembly, first plug-in assembly and second plug-in assembly, thereby improving the stability between adjacent main power failure protectors and branch power failure protectors, reducing the electrical safety problems caused by the disconnection between the main power failure protector and the branch power failure protector, and improving the assembly speed of the main body of the power distribution box.

[0008] Furthermore, the wire adapter assembly includes two wire connection portions arranged parallel to each other. Each wire connection portion includes a first wire rod and a second wire rod. The first wire rod and the second wire rod are attached to each other. The end of the second wire rod near the first plug assembly is provided with a first bend. The first bend causes the second wire rod to separate from the end of the first wire rod near the first plug assembly.

[0009] By adopting the aforementioned technical solution, the conductor adapter assembly is set into two parallel groups. The main power-off protector is connected through the two groups of conductor adapters, which reduces the impact of the large current of the main power-off protector on the electrical connection components, thereby reducing the possibility of overload damage and improving the safety performance of the connection accessories. Each group of conductor adapter assemblies is formed by the bonding of the first conductor rod and the second conductor rod, with a total of two conductors. With the assistance of the first bending part, the connection current when the two conductor connection parts are connected to the first plug-in assembly is increased, thereby improving the stability of the conductor connection parts after being connected to the housing and the main power-off protector. The bonding of the first conductor rod and the second conductor rod increases the cross-sectional area of ​​the conductor connection parts, ensuring the load current transmitted by the conductor connection parts.

[0010] Furthermore, the first plug-in assembly includes a plug-in groove and a plug-in base. The plug-in groove is located on the side wall of the housing, and the plug-in base has multiple bases distributed at the ends of the first guide rod and the first bend. The plug-in base is supported and plugged into the plug-in groove.

[0011] Using the aforementioned technical solution, when installing the first plug-in assembly between the housing and the wire adapter assembly, the plug-in slot is installed on the housing, and the plug-in base is installed at the end of the first wire rod and the first bend. After power-on installation, the plug-in base is installed and plugged into the plug-in slot. While the plug-in base is stably installed, the second wire rod and the first bend connected to the plug-in base are also stably stabilized, thereby improving the stability of the connection accessory.

[0012] Furthermore, the inner wall of the mounting cavity is provided with supporting ribs, which support the first guide rod.

[0013] By adopting the aforementioned technical solution, when the first conductor rod is installed inside the housing, the first conductor rod is supported by the support ribs, which improves the stability of the first conductor rod and reduces the contact range between the first conductor rod and the inner wall of the housing, thereby reducing the impact of the housing on the conductivity efficiency of the first conductor rod.

[0014] Furthermore, the second plug-in assembly includes a first connecting plate and a second connecting plate, the first connecting plate being electrically connected to a wire connecting portion and the second connecting plate being electrically connected to another wire connecting portion.

[0015] When the aforementioned technical solution is adopted, the second plug-in assembly is installed by connecting a first connecting plate to a wire connection part and a second connecting plate to another wire connection part. The first and second connecting plates are connected to the wire connection parts, increasing the number of plug-in parts and plug-in positions, improving the stability of the second plug-in assembly after it is plugged into the trip power disconnector, and reducing the possibility of accidental contact causing the main power disconnector to disconnect from the trip power disconnector.

[0016] Furthermore, the first connecting plate includes a first fixing part, a first adapter part, and a first plug-in piece. The first fixing part is fixedly connected to the wire connection part to conduct electricity. The first adapter part is disposed on the first fixing part. The first plug-in piece is disposed on the end of the first adapter part away from the first fixing part. The first plug-in piece is parallel to the wire connection part and extends toward the first plug-in assembly.

[0017] Using the aforementioned technical solution, when the first connecting plate is connected, it is connected to the wire connecting part through the first fixing part, connected in the middle through the first adapter part, and connected to the leakage current protector through the first plug-in piece at the tail. The first fixing part improves the stability of the first connecting plate, the adapter part facilitates the insertion of the first plug-in piece, and the insertion of the tail through the first plug-in piece improves the stability of the second plug-in assembly, thereby improving the stability of the connecting accessories after connection.

[0018] Furthermore, the outer wall of the cover plate is provided with an insulating mounting seat, which covers the first fixing part, the first adapter part and the second connecting plate, and the plug-in seats of the first plug-in piece and the second connecting plate extend out of the insulating mounting seat.

[0019] Using the aforementioned technical solution, the first connecting plate and the second connecting plate are wrapped by an insulating mounting base, reducing the risk of accidental contact due to the exposure of the first connecting plate and the second connecting plate; when the insulating mounting base is installed, the plug-in parts of the first plug-in piece and the second connecting plate extend out of the insulating mounting base to connect with the leakage current protector, which facilitates the plug-in connection and improves the stability of the plug-in connection.

[0020] Furthermore, the insulating mounting base includes an insulating housing and a cover. The insulating housing is provided with a snap-fit ​​interface, and the cover is provided with a snap-fit ​​hook. The snap-fit ​​hook is attached to the snap-fit ​​interface to install the cover onto the insulating housing.

[0021] By adopting the aforementioned technical solution, a cover is provided on the insulating mounting base and is connected to the locking interface on the insulating mounting base by a hook on the housing, which facilitates the installation and removal of the cover, and in turn facilitates the installation, removal and maintenance of the first connecting plate and the second connecting plate.

[0022] Furthermore, the outer wall of the cover is provided with two parallel ribs, and the insertion parts of the first insertion piece and the second connecting plate extend from the two ribs respectively for insertion connection.

[0023] Using the aforementioned technical solution, after the cover is installed, the insertion part of the second connecting plate and the first insertion piece extend from the two protruding ribs respectively for insertion connection. The protruding ribs stabilize the insertion part of the second connecting plate and the first insertion piece, reducing the possibility of displacement during the insertion process of the insertion part of the second connecting plate and the first insertion piece, which may affect the insertion.

[0024] Furthermore, the first fixing part and a wire connection part are fastened to the housing by screws, and the second connecting plate and another wire connection part are fastened to the housing by screws.

[0025] When the aforementioned technical solution is adopted, the first connecting plate and the second connecting plate are connected to the wire adapter by screws, which facilitates assembly and improves the stability after installation. Attached Figure Description

[0037] The technical solution of this utility model will be described in detail below with specific embodiments. The following specific embodiments can be selected to be combined or substituted with each other according to the actual situation, and the same or similar concepts or processes may not be described again in some embodiments.

[0038] like Figure 1 and Figure 2 As shown, this utility model provides a power distribution module connection accessory, including a housing 1 and a cover plate 2. The housing 1 is disposed on one side of the cover plate 2, forming a mounting cavity 12 between the housing 1 and the cover plate 2. Figure 2 As shown, the housing 1 is provided with a wire adapter assembly 3 located in the mounting cavity 12. One end of the wire adapter assembly 3 is provided with a first plug-in assembly 4 that is embedded in the housing 1. The cover 22 is provided with a second plug-in assembly 5. The second plug-in assembly 5 is connected to the other end of the wire adapter assembly 3. The first plug-in assembly 4 is electrically connected to the main power-off protector, and the second plug-in assembly 5 is electrically connected to the partial power-off protector.

[0039] In this embodiment, as Figure 2 and Figure 3As shown, the wire connection assembly 3 includes two parallel wire connection portions 31 distributed vertically. Each wire connection portion 31 includes a first wire rod 311 and a second wire rod 312. The first wire rod 311 and the second wire rod 312 are in contact with each other. The end of the second wire rod 312 near the first insertion assembly 4 has a first bend 313. The first bend 313 separates the second wire rod 312 from the end of the first wire rod 311 near the first insertion assembly 4, and the first bend 313 extends towards the cover plate 2. By having the first wire rod 311 and the second wire rod 312 in contact, the stability of the connection between the first wire rod 311 and the second wire rod 312 is improved, and the cross-sectional area for conductivity of the first wire rod 311 and the second wire rod 312 is increased. Figure 3 As shown, each of the two wire connection parts 31 includes a first wire rod 311 and a second wire rod 312, so that the two wire connection parts 31 have four connection positions when connected to the first plug-in assembly 4, which improves the stability of the connection between the wire connection part 31 and the housing 1. At the same time, the four separate connection positions reduce the current surge between the main power failure protector and the wire connection part.

[0040] Specifically, such as Figure 2 and Figure 3 As shown, the first plug-in assembly 4 includes a plug-in groove 41 and a plug-in base 42. The plug-in groove 41 is located on the side wall of the housing 1. The plug-in base 42 has multiple locations distributed at the ends of the first conductor rod 311 and the first bend 313. The plug-in base 42 is supported and plugged into the plug-in groove 41. In specific installation, the plug-in groove 41 is embedded in the housing 1. The plug-in groove 41 has multiple first plug-in holes 411. The plug-in base 42 is installed at the ends of the first conductor rod 311 and the first bend 313. The plug-in base 42 is plugged into the first plug-in holes 411 on the plug-in groove 41. The stability of the conductor connection part 31 after installation is improved by plugging the first plug-in holes 411 into the plug-in base 42. The side of the plug-in seat 42 away from the first guide rod 311 is flush with the outer wall of the housing 1 and the plug-in seat 42 is plugged into the plug-in slot 41. The first plug-in hole 411 is provided with a blocking rib. The end of the plug-in seat 42 away from the second guide rod 312 is provided with a snap-fit ​​groove. After the plug-in seat 42 is inserted into the first plug-in hole 411, the blocking rib is snapped into the snap-fit ​​groove, so that the plug-in seat 42 is stably plugged into the outer peripheral wall of the housing 1.

[0041] like Figure 3 As shown, the end of the plug-in socket 42 has a second plug-in hole 421. When conductively connected, the main power-off protector is plugged into the second plug-in hole 421 of the plug-in socket 42. Through the plug-in connection of the second plug-in hole 421, it is adapted to the outer shell of the distribution box, reducing the possibility of the power-off protector and the plug-in socket 42 becoming detached, and improving the stability of the connection between the power-off protector and the connecting accessories.

[0042] To improve the stability of the first guide rod 311 and the second guide rod 312, such as Figure 2 As shown, the inner wall of the housing 1 is provided with a support rib 11. The support rib 11 supports the side of the first conductor rod 311 facing away from the second conductor rod 312, reducing the possibility that the first conductor rod 311 and the second conductor rod 312 are suspended in the mounting cavity 12, thereby improving the stability of the first conductor rod 311 and the second conductor rod 312, and preventing the plug socket 42 from dislodging from the first plug hole 411 due to vibration during transportation, which would affect the stability of the connection of the connecting accessories to the adjacent power failure protector and the installation efficiency of the connection.

[0043] To facilitate the connection of the other side of the accessory, such as Figure 4 and Figure 5 As shown, the second connector assembly 5 includes a first connecting plate 51 and a second connecting plate 52. The first connecting plate 51 and the second connecting plate 52 correspond one-to-one with the two wire connection portions 31. Specifically, as shown... Figure 6 As shown, the first connecting plate 51 includes a first fixing part 511, a first transition part 512, and a first plug-in piece 513. The first fixing part 511 is fixedly connected to the first wire rod 311 and the second wire rod 312 of a wire connection part 31. The first transition part 512 extends along a length direction perpendicular to the length direction of the first wire rod 311, and the length direction of the first transition part 512 is parallel to the distribution plane of the first wire rod 311 and the second wire rod 312. The first plug-in piece 513 is located at the end of the first transition part 512 away from the first fixing part 511, and the length direction of the first plug-in piece 513 is parallel to the length direction of the first wire rod 311 and extends towards the plug-in seat 42. Figure 6 As shown, the second connecting plate 52 includes a second fixing part 521, a second adapter part 522, a third adapter part 523, and a second plug-in piece 524. The second fixing part 521 is fixed to another first guide rod 311. The second adapter part 522 is connected to the second fixing part 521. The second adapter part 522 is parallel to the first adapter part 512 and is lower than the first adapter part 512. The third adapter part 523 is located at the end of the second adapter part 522 away from the second fixing part 521. The third adapter part 523 is perpendicular to the second adapter part 522 and faces the first connecting plate 311. An adapter portion 512 extends such that the tail end of the third adapter portion 523 is close to the first adapter portion 512. The second plug-in piece 524 is located at the tail end of the third adapter portion 523. The first plug-in piece 513 is offset downward relative to the first adapter portion 512, so that the second plug-in piece 524 is parallel to the first plug-in piece 513 and is at the same height. The second plug-in piece 524 is the plug-in portion of the second connecting plate 52, which facilitates the plug-in connection between the second plug-in assembly 5 and the power failure protector. Similarly, within the limited space of the distribution box, the plug-in connection method improves the stability of the second plug-in assembly 5 after plug-in connection.

[0044] To reduce the possibility of leakage current due to contact between the first connecting plate 51 and the second connecting plate 52 and the outside environment after they are energized, such as Figure 7 As shown, the outer wall of the cover plate 2 is provided with an insulating mounting base 21, which encloses the first connecting plate 51 and the second connecting plate 52. Specifically, the first fixing part 511, the first transition part 512, the second fixing part 521, the second transition part 522, and the third transition part 523 are all enclosed in the insulating mounting base 21, which reduces the possibility of leakage after installation and thus improves the electrical safety performance after the connecting accessories are connected.

[0045] To facilitate the disassembly, installation, and maintenance of the first connecting plate 51 and the second connecting plate 52, such as Figure 1 , Figure 7 and Figure 8 As shown, the insulating mounting base 21 is detachably provided with a cover 22. Specifically, the side wall of the insulating mounting base 21 is provided with a locking interface 211, which is located on the side wall of the insulating mounting base 21 opposite to the cover 22. A locking interface 211 is also provided on the bottom wall of the insulating mounting base 21. The cover 22 is provided with a hook 221. When the cover 22 is installed along the length direction of the first conductor rod 311, the hook 221 extends into the insulating mounting base 21 and undergoes elastic deformation after being pressed against the inner wall of the insulating mounting base 21. When the hook 221 slides to the locking interface 211, the hook 221 resets under elastic deformation, so that the hook 221 extends into the locking interface 211, thereby stably installing the cover 22 on the insulating mounting base 21. The first plug-in piece 513 and the second plug-in piece 524 extend out from the cover 22. To facilitate the connection between the hook 221 and the interface 211, the hook 221 has an inclined guide surface on the side facing the inner wall of the insulating mounting base 21. The inclined guide surface abuts against the inner wall of the insulating mounting base 21, which facilitates the elastic deformation of the buckle during the installation of the cover 22, thereby making it easier for the hook 221 to be hooked into the interface 211.

[0046] To improve the stability of the first connector 513 and the second connector 524, such as Figure 6 , Figure 7 and Figure 8 As shown, the cover 22 has a raised rib 222 on the side opposite to the insulating mounting base 21. Two raised ribs 222 are arranged side by side along the length of the first adapter portion 512. The first insertion piece 513 and the second insertion piece 524 extend from the two raised ribs 222 respectively. The setting of the raised ribs 222 makes the first insertion piece 513 and the second insertion piece 524 more stable after extension, reduces the possibility of deflection of the first insertion piece 513 and the second insertion piece 524, and improves the stability after insertion. The cover 22 is also made of insulating material, reducing the possibility of accidental contact with the first connecting plate 51 and the second connecting plate 52 after power is applied, which could lead to electrical safety hazards.

[0047] like Figure 7As shown, an L-shaped gap is formed between the cover 22 and the insulating mounting base 21, which are perpendicular to each other. The second adapter 522 is distributed on one side of the gap, and the first adapter 512 is on the other side of the gap. The L-shaped gap reduces the possibility of mutual interference between the first connecting plate 51 and the second connecting plate 52 between the insulating mounting base 21 and the cover 22.

[0048] In another embodiment, to improve the stability of the connection, when the first fixing part 511 and the second fixing part 521 are fixedly connected, the screw passes through the first fixing part 511 or the second fixing part 521, then passes through the first guide rod and the second guide rod in sequence, and is threadedly connected to the housing 1, thereby fixing the first fixing part 511 and the second fixing part 521. In addition to the first fixing part 511 and the second fixing part 521, the cover 22 is also connected to the housing 1 by screws, which facilitates the disassembly of the cover 22 to repair or replace the wire connection part 31.

[0049] In addition to the preferred embodiments described above, there are other embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection claimed by this utility model.
