Description

Technical Field

[0001] This utility model relates to the technical field of distribution boxes, and in particular to a bridging structure and a distribution box. 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. A distribution box is a low-voltage distribution box constructed by assembling switching equipment, measuring instruments, protective devices, and auxiliary equipment in a closed or semi-closed cabinet or panel according to electrical wiring requirements. During normal operation, circuits can be connected or disconnected using manual or automatic switches. In case of faults or abnormal operation, protective 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 include an outer casing, a panel, and a main unit located inside the casing. The main unit typically includes a main power-off protector and multiple branch power-off protectors. The number of branch power-off protectors is determined by the power consumption needs of the user unit. The main power-off protector and the branch power-off protectors are also connected by a ground wire junction box and a neutral wire junction box. The main power-off protector and the branch power-off protectors are electrically connected by wires.

[0004] When the main power-off circuit breaker and the branch power-off circuit breaker need to be electrically connected on the same side, they are also connected by wires. When connecting the wires, screws are needed to fix them. Since both the main power-off circuit breaker and the branch power-off circuit breaker need to be electrically connected, there are too many wires on the same side. And because the wires have a certain length, they become tangled and messy. The messy wire connection makes it inconvenient for the installation and maintenance of the wires. Utility Model Content

[0005] The purpose of this utility model is to provide a bridging structure and distribution box to solve the problem of inconvenient installation and maintenance caused by messy wires connecting the main power interrupter and the branch power interrupters or connecting two adjacent branch power interrupters. It improves the connection effect between the main power interrupter and the branch power interrupters and between two adjacent branch power interrupters, avoids messy wire connections, and improves the installation and maintenance efficiency of the distribution box.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bridging structure, including an insulating shell base and an insulating shell cover, wherein the insulating shell cover is disposed on the insulating shell base to form a receiving cavity, and a conductor plug-in assembly is disposed in the receiving cavity. A first plug-in assembly is disposed on one side of the conductor plug-in assembly and a second plug-in assembly is disposed on the other side. The first plug-in assembly is used for plugging and connecting with other adjacent bridging structures, and the second plug-in assembly is used for plugging and connecting with a power failure protection device.

[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 on the same side, or connecting two adjacent branch power-off protectors, when connecting the main power-off protector and the branch power-off protector, the first plug-in assembly is connected to the main power-off protector or the connection structure on the main power-off protector, and the second plug-in assembly is connected to the branch power-off protector. If connecting two branch power-off protectors in the middle, the first plug-in assembly is connected to the adjacent bridging structure, thereby connecting multiple branch power-off protectors together in sequence. The conductor plug-in assembly, the first plug-in assembly, and the second plug-in assembly connecting the branch power-off protectors all consist of an insulating shell base and an insulating shell cover. The bridging design avoids the messiness that occurs when wires are connected by screws. During the power-on connection process, the connection is made through the first and second plug-in components, improving the stability of the connection between the main power-off protector and the branch power-off protectors, as well as the stability of the connection between adjacent branch power-off protectors. After the bridging structure is connected, the gap between the outer side of the bridging structure and the outer shell of the distribution box is reduced. Even if some separation occurs after plugging, the small gap prevents the bridging structure from completely detaching from the branch power-off protector or the main power-off protector. Furthermore, the outer side of the bridging structure is insulated, with both the base and the cover being insulating, reducing the possibility of accidental contact and potential electrical safety hazards.

[0008] Furthermore, the second plug-in assembly includes a plug-in plate and a connector. One side of the connector is connected to the conductor plug-in assembly, and the other side is connected to the plug-in plate. The plug-in plate extends out of the insulator base for plug-in connection.

[0009] When the aforementioned technical solution is adopted, the bridging structure is connected to the disconnector through the connector and the conductor plug assembly to conduct electricity, and then the plug plate is plugged into the disconnector to improve the stability of the electrical connection and ensure the stability of the conductivity.

[0010] Furthermore, the insulating shell cover is provided with a sliding paddle and a sliding part. The sliding paddle is slidably disposed on the insulating shell cover, and the sliding part is disposed on the lower side of the sliding paddle. The sliding part is connected to the plug plate so that the plug plate can be driven to extend and plug in through the sliding paddle.

[0011] Using the aforementioned technical solution, a sliding paddle and a sliding part are provided on the insulating shell cover. When using the plug-in plate for connection, the sliding paddle and the sliding part drive the plug-in plate to extend, facilitating plug-in for electrical connection. When transporting or not using the bridging structure, the sliding paddle and the sliding part drive the plug-in plate to retract into the insulating shell base, making the outer periphery of the insulating shell base relatively flat, facilitating transportation and placement.

[0012] Furthermore, a clamping part is provided on the lower side of the sliding part, and the lower end of the clamping part is connected to the plug plate. The clamping part clamps the connector to electrically connect the connector and the plug plate.

[0013] Using the aforementioned technical solution, when the sliding part drives the plug plate to slide, it connects to the plug plate through the clamping part to prevent the sliding part from failing to properly drive the plug plate to extend or retract, thereby ensuring the normal sliding and plugging of the plug plate; the clamping part also clamps with the connector, so that the clamping part slides with the sliding part while the connector is fixed and kept clamped, thereby improving the stability of the electrical connection between the conductor plug assembly and the plug plate.

[0014] Furthermore, the lower side of the sliding paddle is provided with a locking groove, and the upper side of the sliding part is provided with a locking hook. The locking hook extends into the locking groove to hook the sliding paddle so that the sliding paddle drives the sliding part to slide.

[0015] When the aforementioned technical solution is adopted, the sliding paddle is connected to the sliding part by means of a hook and a slot, which facilitates the installation of the sliding paddle and the sliding part and does not affect the sliding paddle and the sliding part from slidingly extending or retracting the plug plate.

[0016] Furthermore, the plug-in plate is provided in two pieces, both of which are slidably disposed on the insulating housing base. The two plug-in plates can extend out of the insulating housing base individually or simultaneously for plug-in connection.

[0017] Using the aforementioned technical solution, two plug-in plates are provided. By plugging the two plug-in plates together, the stability of the connection between the bridging structure and the tripping protection device is improved. The two plug-in plates can extend separately or simultaneously, thereby increasing the installation versatility of the bridging structure.

[0018] Furthermore, the conductor plug-in assembly includes two wire connection parts arranged side by side, and the two plug-in plates are connected one-to-one with the two wire connection parts.

[0019] By adopting the aforementioned technical solution, the wire plug-in assembly is configured as two parallel wire connection parts, and the two plug-in plates are connected one-to-one with the two wire connection parts to improve the stability of the electrical connection.

[0020] Furthermore, the first plug-in assembly includes a plug-in cover plate and a first plug-in pin. The conductor plug-in cover plate is embedded in the insulator base, and the first plug-in pin is located at the end of the conductor plug-in assembly and plugged into the conductor plug-in cover plate. The first plug-in pin extends out of the insulator base for plug-in connection.

[0021] By adopting the aforementioned technical solution, the first plug-in component is configured as a plug-in cover plate and a first plug-in pin. The first plug-in pin is plugged into the plug-in cover plate, which stabilizes the first plug-in pin and reduces the possibility that the first plug-in pin may be bent or deviated, thus affecting the plug-in effect and plug-in efficiency.

[0022] Furthermore, the conductor plug-in assembly is provided with a third plug-in assembly in the middle. The third plug-in assembly includes a connecting conductor, a plug-in groove, and a plug-in seat. The connecting conductor is integrally connected with the conductor plug-in assembly. The plug-in groove is located on the base of the insulating housing. The plug-in seat is located at the tail end of the connecting conductor and is embedded in the plug-in groove. The plug-in seat is plugged into and connected to the first plug-in assembly of the adjacent bridging structure.

[0023] Using the aforementioned technical solution, when the bridging structure connects to the middle disconnector, the bridging structure needs to be connected to the middle disconnector and also electrically connected to the disconnectors on both sides. By setting a third plug-in component, the third plug-in component and the first plug-in component of the adjacent bridging structure can make the three adjacent disconnectors electrically connected to each other, ensuring the stability of the connection and simplifying the connection structure.

[0024] Furthermore, in order to achieve the above objectives, the present invention adopts the following technical solution: a distribution box, including a main power-off protector, a plurality of parallel distributed branch power-off protectors, and a plurality of the above-mentioned bridging structures, wherein the main power-off protector and the branch power-off protectors, as well as two adjacent branch power-off protectors, are electrically connected through the bridging structures.

[0025] When the aforementioned technical solution is adopted, and the bridging structure is set between the main power-off protector and the branch power-off protectors, the bridging structure with the first plug-in component, the second plug-in component, and the third plug-in component is connected in the middle position, and the bridging structure with only the first plug-in component and the second plug-in component is connected between the two branch power-off protectors at the outermost edge. This facilitates the electrical connection between the power-off protectors, improves the stability of the connection, facilitates maintenance, and the insulating shell base and insulating shell cover avoid the safety hazard of accidental contact.

[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 2As shown, this utility model provides a bridging structure, including an insulating housing base 1 and an insulating housing cover 2. The insulating housing cover 2 is fixedly connected to the insulating housing base 1 by screws, forming a receiving cavity. A conductor plug-in assembly 3 is provided within the receiving cavity. A first plug-in assembly 4 is provided on one side of the conductor plug-in assembly 3, and a second plug-in assembly 5 is provided on the other side. The conductor plug-in assembly 3 is fixedly installed on the insulating housing base 1 through the first plug-in assembly 4 and the second plug-in assembly 5. The first plug-in assembly 4 is used for plug-in connection with other adjacent bridging structures, and the second plug-in assembly 5 is used for plug-in connection with a power-off device. The plug-in connection of the first plug-in assembly 4 and the second plug-in assembly 5 avoids messy wire connections; the enclosure of the insulating housing base 1 and the insulating housing cover 2 avoids the safety hazard of accidental electric shock during installation or maintenance; furthermore, the bridging structure electrically connects the power-off device, reducing the gap between the power-off device and the housing, thereby reducing the possibility of the second plug-in assembly 5 detaching from the power-off device.

[0039] In this embodiment, as Figure 1 and Figure 2 As shown, the second plug-in assembly 5 includes a plug-in plate 51 and a connector 52. One side of the connector 52 is connected to the conductor plug-in assembly 3, and the other side is connected to the plug-in plate 51. The plug-in plate 51 extends out of the insulating housing base 1 for plug-in connection. It is electrically connected to the conductor plug-in assembly 3 through the connector 52, and the plug-in plate 51 is electrically connected to the connector 52. Then, it is plugged into the power failure protector through the plug-in plate 51 to improve the conductivity stability after the plug-in plate 51 is plugged in.

[0040] To facilitate the transportation, placement, and installation of the bridging structure, such as Figure 2As shown, the insulating shell cover 2 is provided with a sliding paddle 21 and a sliding part 22. The sliding paddle 21 is slidably disposed on the insulating shell cover 2. The sliding part 22 is connected to the lower side of the sliding paddle 21. The sliding part 22 is connected to the plug plate 51 so that the plug plate 51 can be extended and plugged in by the sliding paddle 21. When the sliding paddle 21 and the sliding part 22 are specifically connected, the lower side of the sliding paddle 21 is provided with a locking groove 211, and the upper side of the sliding part 22 is provided with a hook, which is a first hook 221. The first hook 221 extends into the locking groove 211 to hook and connect the sliding paddle 21 so that the sliding paddle 21 can drive the sliding part 22 to slide. More specifically, two blocking ribs 21 are distributed on the lower side of the sliding paddle 21 in the sliding direction of the sliding paddle 21. 2. The first hook 221 is located between the two blocking ribs 212. The locking groove 211 is provided with a second hook 213 that locks the first hook 221 along the length of the first hook 221. The sliding paddle 21 is engaged with the sliding part 22. Before the bridging structure is transported, the sliding part 22 is moved by moving the sliding paddle 21, thereby causing the plug plate 51 to retract into the insulating housing base 1. This prevents the plug plate 51 from bending due to collision during transportation, which would affect the plug connection of the plug plate 51. Alternatively, when the bridging structure is not used, the plug plate 51 can also be retracted to reduce the external volume and sharp edges of the bridging structure, making it easier to place and transport, and reducing the possibility of the plug plate 51 bending due to pressure during transportation or after placement.

[0041] Furthermore, such as Figure 2 and Figure 3 As shown, the connector 52 includes a first connecting portion 521 and a second connecting portion 522. The first connecting portion 521 is disposed perpendicular to the bottom wall of the receiving cavity and is fixedly connected to the conductor plug-in assembly 3 by screws. The second connecting portion 522 is disposed at the top of the first connecting portion 521 and parallel to the length direction of the plug-in plate 51. A clamping portion 53 is provided between the sliding portion 22 and the plug-in plate 51. One side of the clamping portion 53 is connected to the lower side of the sliding portion 22, and the other side is connected to the plug-in plate 51. Both the second connecting portion 522 and the clamping portion 53 are... Two sets are provided along the edge. Specifically, the clamping part 53 includes a first clamping rod 531 and a second clamping rod 532. A clamping gap 533 is formed between the first clamping rod 531 and the second clamping rod 532. The second connecting part 522 extends into the clamping gap 533. During the sliding process of the sliding part 22 driven by the sliding paddle 21, the second connecting part 522 remains inserted in the clamping gap 533, so that the conductor plug-in assembly 3, the first connecting part 521, the second connecting part 522, the second clamping rod 532 and the plug-in plate 51 are electrically connected.

[0042] To improve the stability of the bridging structure plug-in connection, two plug-in plates are provided on the plug-in plate 51, such as... Figure 4 and Figure 5As shown, the first plug-in plate 511 and the second plug-in plate 512 are respectively provided. The first plug-in plate 511 and the second plug-in plate 512 are respectively provided with a sliding paddle 21, a sliding part 22 and a clamping part 53. The corresponding conductor plug-in assembly 3 includes two wire connection parts 31 arranged side by side. The first plug-in plate 511 and the second plug-in plate 512 are respectively connected to the two wire connection parts 31 one by one through connectors 52. The specific length and shape of the two connectors 52 can be adapted to the size of the installation space. The first plug-in plate 511 and the second plug-in plate 512 are plugged in to improve the stability of the plug-in connection and reduce the possibility of the bridging structure and the power failure protector being disconnected and affecting the conductivity.

The first plug-in pins 42 are located at the end of the conductor plug-in assembly 3 and plugged into the plug-in sealing plate 41. The first plug-in pins 42 extend out of the insulating housing base 1 for plug-in connection. Specifically, the conductor plug-in assembly 3 includes wire connection parts 31 arranged side by side. The ends of the two conductor plug-in assemblies 3 are each divided into four connection points. There are eight first plug-in pins 42. Every four first plug-in pins 42 form a group. The two groups of first plug-in pins 42 are connected one-to-one with the two wire connection parts 31. The four first plug-in pins 42 in the same group are connected one-to-one with the four connection points of the conductor plug-in assembly 3. Through the plug-in connection of the eight first plug-in pins 42, the stability of the conductor plug-in assembly 3 in the receiving cavity is improved, and the stability of the plug-in connection of the first plug-in assembly 4 is also improved.

Figure 8As shown, the insertion slot 62 is provided with multiple first insertion holes 621. A retaining rib 622 is provided in the middle portion of each first insertion hole 621. A insertion base 63 is located at the tail end of the connecting conductor 61, and multiple insertion bases 63 are provided at the tail end of the connecting conductor 61. The insertion base 63 is inserted into the first insertion hole 621. A second insertion hole 631 is provided at the end of the insertion base 63 away from the connecting conductor 61. The number of second insertion holes 631 is the same as the number of first insertion pins 42. Each first insertion hole... A connector 63 is provided with two second connector holes 631. The connector 63 between the two second connector holes 631 is provided with a snap-fit ​​groove 632. After the connector 63 is inserted into the first connector hole 621, the snap-fit ​​rib 622 snaps into the snap-fit ​​groove 632, which improves the stability of the connector 63 and the connector groove 62. When adjacent bridging structures are connected, multiple first connector pins 42 on one side are inserted into multiple second connector holes 631 on the other side for one-to-one corresponding connection.

[0045] When designing a bridging structure, a bridging structure with only the first plug-in component 4 and the second plug-in component 5 can be used between the two sidemost power-off protectors. Alternatively, a bridging structure with two plug-in boards 51 or one plug-in board 51 can be selected depending on the width and number of pins of the power-off protector.
