Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to an emergency jump-connection and repair distribution box. Background Technology

[0002] Emergency jump-connection and repair distribution boxes are emergency power distribution devices designed specifically to deal with sudden power system failures. They can quickly provide temporary power supply when the main power supply is interrupted or equipment fails, while supporting jump-connection and rapid repair operations to ensure the continuous operation of critical equipment and the stability of power supply.

[0003] Currently, while existing emergency jump-connection repair distribution boxes can cut off the circuit to deal with emergencies through the protector, they cannot disconnect the electrical connection when the protector itself malfunctions or misoperates, which can easily lead to equipment failure or even safety accidents. At the same time, the lack of a convenient manual unlocking function affects the convenience and safety of operation. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of existing technologies, such as the inability to disconnect electrical connections, which can easily lead to equipment failure or even safety accidents, and the lack of convenient manual unlocking function, which affects the convenience and safety of operation. Therefore, an emergency jump-connection repair distribution box is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] Emergency jumper repair distribution boxes include:

[0007] The enclosure has fixed brackets on its top and bottom walls. The same mounting plate is fixed on one side of each of the two fixed brackets. An AC connector and a DC connector are fixedly fixed on one side of the mounting plate, respectively. A bracket is fixed on one side of the mounting plate above the AC connector and the DC connector, and an AC circuit breaker and a DC circuit breaker are respectively clamped on the outside of the bracket.

[0008] Protection mechanisms are installed on AC circuit breakers and DC circuit breakers and are used to disconnect electrical connections thereon.

[0009] In one possible design, the protection mechanism includes connecting seats that are hinged to the bottom of the AC circuit breaker and the DC circuit breaker respectively. Multiple evenly distributed electrical contacts are fixedly arranged on the top of each of the two connecting seats. Electrical contact pieces, in the same number and corresponding in position as the electrical contacts, are embedded in the bottom of both the AC and DC circuit breakers. Connecting frames are fixedly arranged on one side of each of the two connecting seats, and a latching groove is opened on one side of each of the two connecting frames. A latching block, adapted to the latching groove and capable of disengaging, is fixedly arranged on one side of each of the AC and DC circuit breakers. An electric push rod is embedded on one side of each of the AC and DC circuit breakers above the latching block.

[0010] In one possible design, the bottom of the AC circuit breaker and the DC circuit breaker are symmetrically fixed with springs next to the electrical contacts.

[0011] In one possible design, the bottom of the connector has a number of wire holes corresponding to the number of electrical contacts, and an insulating sleeve is fixedly installed around the outer ring of each of the multiple wire holes.

[0012] In one possible design, both the AC circuit breaker and the DC circuit breaker are equipped with a display screen on one side, the AC circuit breaker is electrically connected to an AC connector, the DC circuit breaker is electrically connected to a DC connector, and both the AC circuit breaker and the DC circuit breaker are equipped with an alarm with audible and visual functions on their tops.

[0013] In one possible design, a protective plate is fixedly installed inside the enclosure. One side of the protective plate has slots to allow the AC circuit breaker, DC circuit breaker, AC connector, and DC connector to be exposed. Multiple control buttons are embedded on one side of the protective plate.

[0014] In one possible design, a lid is hinged to one side of the box body, and the same braided soft copper wire is fixedly installed on one side of the box body and the lid. The box body and the lid are locked together by a door lock.

[0015] In one possible design, heat dissipation holes are provided on both sides of the enclosure, and a cover is fixedly installed on the outer side of the enclosure at the heat dissipation holes.

[0016] In this application, upon initial use, the AC circuit breaker and DC circuit breaker are first installed on the brackets, ensuring that the electrical contacts at their bottoms correspond to the electrical contacts on the connector. The fasteners engage with the slots on the connector to make electrical contact between the electrical contacts and the electrical contacts. Then, the wiring harness is passed through the bottom of the enclosure into the enclosure. The AC wire is then connected to the AC connector, and the DC wire is connected to the DC connector. The AC connector is then connected to the AC circuit breaker through the wiring harness through the wiring port, and the DC connector is connected to the DC circuit breaker through the wiring harness through the wiring port. During this process, the wiring is ensured to be secure and reliable to avoid short circuits or open circuits. The power supply is then turned on. At this time, the displays of the AC and DC circuit breakers show the AC and DC values ​​respectively and monitor parameters such as current and voltage in real time.

[0017] When there are abnormalities in parameters such as current and voltage (e.g., overload, short circuit) and the protector fails to disconnect the power, the alarm will first issue an audible and visual alarm. When the alarm sounds, it triggers the electric push rod to work. The output end of the electric push rod extends rapidly and pushes the connecting frame to move in a specific direction. This displacement causes the pre-set slot on the connecting frame to separate from the originally engaged buckle. This mechanical unlocking process then causes the physical connection and locking state between the connecting seat and the AC circuit breaker or DC circuit breaker to be released. At this time, the spring sheet assists in pushing the connecting seat downward through its own elasticity, thereby causing the electrical contacts integrated on the connecting seat to disengage from the corresponding electrical contacts, thus completely disconnecting the electrical connection between the two.

[0018] In addition, to address such emergencies or routine maintenance needs, a manual unlocking mechanism has been designed, allowing operators to mechanically separate the latch from the connecting frame by directly prying the top edge of the connecting frame. This achieves the same purpose of disconnecting the electrical connection between the AC circuit breaker or DC circuit breaker and the connecting base, ensuring system safety and ease of maintenance.

[0019] This utility model has the following beneficial effects:

[0020] This utility model achieves rapid and safe protection for AC and DC circuit breakers through the setting of a protection mechanism. It can automatically disconnect the electrical connection when the electrical parameters are abnormal, effectively preventing equipment failure and safety accidents. At the same time, it provides a manual unlocking function to ensure the safety and flexibility of operation.

[0021] This utility model achieves reliable electrical connection and grounding protection between the metal box door and the metal box body by setting up braided soft copper wire, which enhances the safety performance of the distribution box. At the same time, it has good flexibility and corrosion resistance, ensuring long-term stable operation under different environmental conditions. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0029] Example 1

[0030] Reference Figure 1-5 Distribution box, including:

[0031] The enclosure 1 is made of high-quality metal material to ensure sufficient strength and durability during use. The top and bottom walls inside the enclosure 1 are fixed with brackets 301. These brackets 301 are used to support and fix the components to be installed later. On one side of the two brackets 301, a mounting plate 3 is fixed. The mounting plate 3 serves as a support platform for the AC connector 4 and the DC connector 5. The two connectors are located on one side of the mounting plate 3 respectively, in a symmetrical distribution, which facilitates the access and distribution of power lines.

[0032] Above the mounting plate 3, there is a bracket that is fixed to hold the AC circuit breaker 6 and the DC circuit breaker 7. These two circuit breakers are responsible for the interruption and protection of AC and DC power respectively, and are one of the core components of the distribution box.

[0033] To further enhance the safety and reliability of the distribution box, a protection mechanism is also provided. This protection mechanism includes a connecting seat 10 hinged to the bottom of the AC circuit breaker 6 and the DC circuit breaker 7 respectively. The top of the connecting seat 10 is fixed with multiple evenly distributed electrical contacts 11, which correspond to the electrical contact pieces 13 at the bottom of the circuit breaker for electrical connection. When the circuit needs to be disconnected, the protection mechanism can act quickly to separate the electrical contacts 11 from the electrical contact pieces 13. To achieve the rapid action of the protection mechanism, a connecting frame 14 is fixed to one side of the connecting seat 10. The connecting frame 14 has a latching groove. The AC circuit breaker 6 and the DC circuit breaker 7 are fixed to one side with latching blocks 15 that are adapted to the latching groove. When the latching block 15 is engaged in the latching groove, the circuit breaker and the connecting seat 10 are locked together. When the circuit needs to be disconnected, the connecting frame 14 can be pushed by the electric push rod 16 to disengage the latching groove from the latching block 15, thereby achieving rapid unlocking and disconnection of the circuit breaker.

[0034] In addition, the bottom of the AC circuit breaker 6 and the DC circuit breaker 7 is provided with spring contacts 17. These spring contacts 17 can help push the connector 10 to open when the power is off, ensuring that the circuit can be quickly and completely disconnected. At the same time, the bottom of the connector 10 is provided with a wire through hole 12 and equipped with an insulating sleeve to ensure safe connection and insulation protection of the line.

[0035] In order to monitor the operating status of the distribution box in real time, a display screen 8 is installed on one side of both the AC circuit breaker 6 and the DC circuit breaker 7 to display parameters such as current and voltage. At the same time, each of these two circuit breakers is also equipped with an alarm 9 with sound and light functions, which can issue an alarm signal when the parameters are abnormal.

[0036] This application can be used in the field of emergency jump-connection and repair of distribution boxes, and can also be used in other fields applicable to this application.

In order to facilitate operation and maintenance, a protective plate 18 is fixed inside the box 1. The protective plate 18 has slots to facilitate the exposure and operation of the AC circuit breaker 6, DC circuit breaker 7, AC connector 4 and DC connector 5. In addition, multiple control buttons 19 are embedded in the protective plate 18 to control various functions of the distribution box.

[0039] A cover 2 is hinged to one side of the enclosure 1. The cover 2 is locked to the enclosure 1 by a door lock 201. To ensure the grounding safety of the enclosure 1, the same braided soft copper wire 21 is also fixed to one side of the enclosure 1 and the cover 2.

[0040] In order to maintain ventilation and heat dissipation inside the distribution box, heat dissipation holes are provided on both sides of the box 1, and a cover 20 is fixed on the outside of the heat dissipation holes to prevent dust and debris from entering the box 1.

[0041] However, as is well known to those skilled in the art, the working principles and wiring methods of AC connector 4, DC connector 5, AC circuit breaker 6, DC circuit breaker 7, display screen 8, alarm 9, electric actuator 16 and control button 19 are commonplace and belong to conventional means or common knowledge.
