Description

Technical Field

[0001] This utility model relates to the field of distribution box technology, and in particular to a wiring connector and distribution box with adaptive protection function. Background Technology

[0002] Distribution boxes, as one of the important pieces of equipment in power systems, are widely used in industrial, commercial, and civil buildings, responsible for the distribution and control of electrical energy. Their main function is to receive power and distribute it to various terminal devices according to the load requirements.

[0003] During normal use of a distribution box, over time, the electrical components will experience wear and tear due to factors such as current load, equipment aging, and changes in ambient temperature. This can easily lead to overheating or heating at the power connection points. Overheating is particularly severe in environments with high current loads or high ambient temperatures. Overheating of the power connection in the distribution box can not only cause the wiring materials to melt or burn, leading to equipment malfunctions or damage, but in severe cases, it can also cause a fire, posing unpredictable safety hazards.

[0004] Therefore, how to quickly cut off the power supply to prevent fire when the power wiring of the distribution box overheats has become an urgent technical problem to be solved. Utility Model Content

[0005] The main purpose of this utility model is to provide a wiring connector and distribution box with adaptive protection function, which aims to quickly cut off the power supply when the power wiring part of the distribution box overheats, so as to avoid fire.

[0006] To achieve the above objectives, this utility model proposes a wiring connector with adaptive protection function, comprising:

[0007] The mounting base has two first slots for the power supply core to pass through, and the two first slots are symmetrical about the center of the first end of the mounting base.

[0008] The movable seat can be snapped onto the first end of the fixed seat and form an assembly space between it and the fixed seat. The movable seat is provided with a second core slot that corresponds one-to-one with the first core slot and whose axis coincides with the first core slot.

[0009] A switching seat, located within the assembly space, is used to connect or disconnect the electrical connection between the battery cell in the first core slot and the battery cell in the second core slot.

[0010] The detection unit is used to detect the temperature of the battery cell; and

[0011] A drive assembly, connected to the switching base, drives the switching base to rotate when the temperature of the battery cell rises, thereby cutting off the electrical connection between the battery cell in the first slot and the battery cell in the second slot.

[0012] The wiring connector uses a detection unit to monitor the battery cell temperature in real time and a drive assembly to rotate the switching seat to disconnect the electrical connection. This automatically triggers a protection mechanism when the battery cell temperature rises, preventing equipment malfunctions or damage due to overheating. This design improves the safety of the wiring connector and avoids electrical accidents.

[0013] In one embodiment of this application, the switching base is composed of two conductive movable cells and two insulating movable plates arranged in an alternating cross shape, and the center point of the switching base coincides with the center point of the cross section of the fixed base.

[0014] The switching socket, with its alternating cross-shaped arrangement of movable battery cells and a movable plate, not only provides precise electrical connection switching but also ensures reliable disconnection in case of overheating. This design gives the switching socket excellent stability during rotation, preventing poor battery cell contact or current failure due to asymmetrical rotation, thereby further enhancing the safety and reliability of the connector.

[0015] In one embodiment of this application, the driving component includes:

[0016] A semi-circular cover is fixedly connected to the outer wall of the first end of the fixed base, and the semi-circular cover is provided with a sliding groove;

[0017] A semi-circular spring is disposed within the semi-circular cover; and

[0018] The drive plate is connected to the end of the semi-circular spring, is slidably embedded in the sliding groove, and drives the switching seat to rotate through the connecting block.

[0019] The drive assembly uses the elastic force of a semi-circular spring to drive the drive plate to slide, and the connecting block to rotate the switching seat. It can start quickly when the cell temperature rises, ensuring the electrical connection of the wiring connector is disconnected. The design of the semi-circular cover and sliding groove ensures smooth sliding of the drive plate, making the rotation of the switching seat more stable and precise.

[0020] In one embodiment of this application, the detection unit includes:

[0021] Thermal expansion ring, limiting rod, return spring, heat-conducting pillar, among which:

[0022] The fixed base is provided with a detection groove, and the limiting rod is located in the detection groove and can reciprocate along the length of the detection groove. The limiting rod is provided with a flange, and a return spring is provided on the side of the flange away from the extended end of the limiting rod. A thermal expansion ring is provided on the side of the flange near the extended end of the limiting rod, which can press the flange towards the return spring when heated, so that the limiting rod retracts into the detection groove. The heat-conducting column penetrates the side wall of the detection groove and communicates with the core slot. The switching base is provided with a limiting groove that engages with the limiting rod.

[0023] The detection unit, through the cooperation of a thermal expansion ring, a limiting rod, a return spring, and a heat-conducting column, achieves automatic response of the switching seat to temperature changes. The thermal expansion ring expands upon heating, driving the limiting rod to retract into the detection slot, thereby releasing the restriction on the switching seat and ensuring that it can quickly rotate and disconnect the electrical connection in case of overheating. This detection unit not only monitors the temperature changes of the battery cells in real time but also automatically triggers a protection mechanism when the temperature is too high, preventing electrical equipment malfunctions or fires caused by overheating, thus ensuring the stability and reliability of the equipment.

[0024] In one embodiment of this application, the movable seat is provided with a synchronization groove, and the connecting block is provided with a synchronization rod. The synchronization rod is inserted into the synchronization groove so as to drive the movable seat to rotate when the switching seat rotates.

[0025] The coordination of the synchronizing rod and synchronizing groove allows the switching seat and the movable seat to rotate synchronously. This structure ensures that the movable seat moves synchronously with the switching seat as it rotates, guaranteeing a smooth and reliable disconnection process for the entire electrical connection. Simultaneously, the synchronous rotation design avoids mechanical shocks or jamming caused by asynchronous rotation of the movable seat, further improving the stability and safety of the wiring connector.

[0026] In one embodiment of this application, a semi-circular groove is provided on the inner sidewall of the assembly space, and a pressure block that can slide in the semi-circular groove is connected to the drive plate. A miniature pressure rod for detecting the position of the pressure block is provided at the bottom of the semi-circular groove.

[0027] The semi-circular groove and the pressure block's coordinated design allow the drive plate to slide smoothly and precisely during operation, bringing the pressure block into contact with the miniature pressure rod, thus monitoring the pressure block's sliding position. The miniature pressure rod's detection function allows for real-time sensing of the pressure block's position changes, providing data support for equipment safety monitoring. In the event of overheating or other abnormalities, the interaction between the pressure block and the miniature pressure rod can promptly report the equipment status and trigger an alarm.

[0028] In one embodiment of this application, an indicator light is provided on the outer wall of the assembly space, and a miniature pressure rod is electrically connected to the indicator light. When the pressure block contacts the miniature pressure rod, the indicator light is lit.

[0029] The combined design of the indicator light and miniature pressure lever provides an intuitive fault alarm by immediately illuminating the indicator light when the pressure block contacts the miniature pressure lever. This function effectively improves the safety of the wiring connector, alerting operators to take immediate action in case of abnormal conditions such as overheating, thereby preventing more serious electrical faults or fire accidents.

[0030] In one embodiment of this application, the first end of the fixed seat is provided with a limiting ring, and the switching seat is rotatably disposed inside the limiting ring.

[0031] The limit ring provides necessary support and constraint for the rotation of the switching unit, enabling it to accurately and stably disconnect the electrical connection under overheating conditions, thus ensuring electrical safety. Through the structural design of the limit ring, the rotation of the switching unit is effectively restricted, enhancing not only the stability of the equipment but also ensuring the rotation angle and operational reliability of the switching unit.

[0032] In one embodiment of this application, the arc angle of the semi-arc chute is set to 90 degrees, and the rotation angle of the switching seat is limited to 90 degrees.

[0033] By setting the arc angle of the semi-circular slide to 90 degrees, the rotation angle of the switching unit is limited to a range of 90 degrees, enabling the switching unit to accurately disconnect the electrical connection within a predetermined angle. This not only ensures that the switching unit can stably disconnect the circuit when overheated, but also avoids mechanical damage or electrical failures caused by excessive rotation angles, thereby improving the safety and reliability of the wiring connector.

[0034] This application also discloses a distribution box, including a box body, wherein the box body is provided with a wiring connector with adaptive protection function as described in any of the above claims.

[0035] By adopting the above technical solution, the wiring connector monitors the cell temperature in real time through a detection unit and drives the switching seat to rotate and disconnect the electrical connection via a drive component. This automatically triggers a protection mechanism when the cell temperature rises, preventing equipment malfunctions or damage caused by overheating. This design improves the safety of the wiring connector and avoids electrical accidents. Attached Figure Description

[0046] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following specific embodiments are only used to explain this utility model and do not constitute a limitation on this utility model.

[0047] like Figures 1 to 6 As shown, in order to achieve the above objectives, this utility model proposes a wiring connector with adaptive protection function, comprising:

[0048] The fixing base 1 is provided with two first core slots for the power supply core to pass through, and the two first core slots are symmetrical about the center of the first end of the fixing base 1;

[0049] The movable seat 2 can be snapped onto the first end of the fixed seat 1 and form an assembly space between it and the fixed seat 1. The movable seat 2 is provided with a second core slot 4 that corresponds one-to-one with the first core slot and whose axis coincides with the first core slot.

[0050] Switching seat 6 is located in the assembly space and is used to connect or disconnect the electrical connection between the battery cell in the first core slot and the battery cell in the second core slot 4.

[0051] The detection unit is used to detect the temperature of the battery cell; and

[0052] A drive assembly, connected to the switching base 6, drives the switching base 6 to rotate when the temperature of the battery cell rises, thereby cutting off the electrical connection between the battery cell in the first core slot and the battery cell in the second core slot 4.

[0053] Specifically, the fixed base 1 has two first slots for the power supply core to pass through, and the two first slots are symmetrically arranged about the center of the first end of the fixed base 1 to ensure that the power supply core can be accurately connected to the first slot and has good symmetry to ensure the stability of the electrical connection. The movable base 2 can be snapped onto the first end of the fixed base 1, forming an assembly space between the movable base 2, the assembly set 3, and the switching base 6. The movable base 2 has a second slot 4 that coincides with the axis of the first slot. The second slot 4 corresponds one-to-one with the first slot to ensure that the battery core can be accurately inserted and conduction. The switching base 6 is located in the assembly space. The function of the switching base 6 is to connect or disconnect the electrical connection between the battery core in the first slot and the battery core in the second slot 4, thereby ensuring the normal transmission of current or disconnecting the current and protecting the equipment from overheating and electrical faults. The detection unit is used to detect the temperature of the battery core in real time and monitor the temperature change of the battery core so that it can react in time when the battery core temperature is abnormal. The drive assembly is connected to the switching base 6. When the temperature of the battery cell rises to a certain threshold, the drive assembly rotates the switching base 6 by acting on it, thereby cutting off the electrical connection between the battery cells and effectively preventing overheating from causing electrical faults or fire risks.

[0054] By adopting the above technical solution, the wiring connector monitors the cell temperature in real time through a detection unit and drives the switching seat 6 to rotate and disconnect the electrical connection via a drive assembly. This automatically triggers a protection mechanism when the cell temperature rises, preventing equipment malfunctions or damage caused by overheating. This design improves the safety of the wiring connector and avoids electrical accidents.

[0055] In one embodiment of this application, the switching base 6 is composed of two conductive movable cells 61 and two insulating movable plates 62 arranged in an alternating cross shape, and the center point of the switching base 6 coincides with the center point of the cross section of the fixed base 1.

[0056] Specifically, the switching base 6 consists of two conductive movable cells 61 and two insulating movable plates 62 arranged in an alternating cross pattern, with the center point of the switching base 6 coinciding with the center point of the cross section of the fixed base 1. The alternating cross arrangement of the movable cells 61 and movable plates 62 ensures that the switching base 6 can switch electrical connection states uniformly and stably during rotation. The movable cells 61 are made of conductive material, ensuring current transmission in a conductive state, while the movable plates 62 are made of insulating material, providing current isolation. During assembly, the design of the switching base 6 allows for the disconnection or connection of the conductive cells through rotation, ensuring the reliability and safety of the current connection. Furthermore, the coincidence of the center point of the switching base 6 with the center point of the cross section of the fixed base 1 ensures good balance during rotation, preventing electrical connection abnormalities caused by uneven or unstable rotation.

[0057] By adopting the above technical solution, the switching socket 6, with its cross-shaped alternating arrangement of movable battery cells 61 and movable plate 62, not only provides precise electrical connection switching but also ensures reliable electrical connection disconnection in case of overheating. This design gives the switching socket 6 good stability during rotation, avoiding poor battery cell contact or current connection failure caused by asymmetrical rotation, thereby further improving the safety and reliability of the wiring connector.

[0058] In one embodiment of this application, the driving component includes:

[0059] A semi-circular cover 17 is fixedly connected to the outer wall of the first end of the fixed base 1, and a sliding groove 19 is provided on the semi-circular cover 17.

[0060] A semi-circular spring 5 is disposed within the semi-circular cover 17; and

[0061] The drive plate 14 is connected to the end of the semi-circular spring 5, and is slidably embedded in the sliding groove 19, and drives the switching seat 6 to rotate through the connecting block 16.

[0062] Specifically, the drive assembly includes a semi-circular cover 17, a semi-circular spring 5, and a drive plate 14. The semi-circular cover 17 is fixedly connected to the outer wall of the first end of the fixed base 1 and is provided with a sliding groove 19. The design of the sliding groove 19 provides sliding space for the drive plate 14, allowing the drive plate 14 to move smoothly within the groove. The semi-circular spring 5 is located inside the semi-circular cover 17, with its end connected to the drive plate 14, providing a certain elasticity. When the cell temperature is too high, the spring drives the drive plate 14 to move by compression or stretching. The drive plate 14 is slidably embedded in the sliding groove 19. When the semi-circular spring 5 deforms, the drive plate 14 slides forward or backward through the sliding groove 19 and drives the switching base 6 to rotate through the connecting block 16, thereby realizing the electrical connection disconnection function of the switching base 6. Through the linkage of the above structural components, the drive assembly can effectively respond to changes in cell temperature and automatically drive the switching base 6 to rotate and disconnect the electrical connection when the cell overheats.

[0063] Using the above technical solution, the drive assembly drives the drive plate 14 to slide through the elastic force of the semi-circular spring 5, and realizes the rotation of the switching seat 6 through the connecting block 16. It can start quickly when the cell temperature rises, ensuring the electrical connection of the wiring connector is disconnected. The design of the semi-circular cover 17 and the sliding groove 19 ensures the smooth sliding of the drive plate 14, making the rotation process of the switching seat 6 more stable and precise.

[0064] In one embodiment of this application, the detection unit includes:

[0065] Thermal expansion ring 11, limiting rod 7, return spring 8, heat-conducting column 12, wherein:

[0066] The fixed base 1 is provided with a detection groove, and the limiting rod 7 is partially disposed in the detection groove and can reciprocate along the length direction of the detection groove. The limiting rod 7 is provided with a flange 9, and a return spring 8 is provided on the side of the flange 9 away from the extended end of the limiting rod 7. A thermal expansion ring 11 is provided on the side of the flange 9 near the extended end of the limiting rod 7, which can press the flange 9 towards the return spring 8 when heated, so that the limiting rod 7 retracts into the detection groove. The heat-conducting column 12 penetrates the side wall of the detection groove and communicates with the core slot. The switching base 6 is provided with a limiting groove 13 that engages with the limiting rod 7.

[0067] Specifically, the detection unit includes a thermal expansion ring 11, a limiting rod 7, a return spring 8, and a heat-conducting column 12. The fixed base 1 has a detection groove, and the limiting rod 7 is partially located within the detection groove, allowing it to reciprocate along the length of the groove. The limiting rod 7 has a flange 9, and the side of the flange 9 furthest from the extended end of the limiting rod 7 abuts against the return spring 8. The return spring 8 ensures that the limiting rod 7 remains in its original position under normal conditions. When the cell temperature rises, the thermal expansion ring 11 expands due to heat, pressing against the return spring 8, causing the limiting rod 7 to retract into the detection groove. The thermal expansion ring 11 senses changes in cell temperature through its expansion and acts on the limiting rod 7, driving it to reciprocate within the detection groove, thus releasing the restriction on the switching base 6. The heat-conducting column 12 penetrates the side wall of the detection groove and communicates with the core slot, transferring heat from the core slot to the thermal expansion ring 11. When the battery cell overheats, the heat-conducting pillar 12 directs the heat to the thermal expansion ring 11, causing the thermal expansion ring 11 to expand. This causes the limiting rod 7 to shift, further triggering the switching seat 6 to rotate and disconnect the electrical connection. The switching seat 6 is provided with a limiting groove 13 that engages with the limiting rod 7. When the limiting rod 7 shifts, the limiting groove 13 and the limiting rod 7 cooperate with each other, thereby ensuring that the switching seat 6 can rotate accurately after the limiting rod 7 is released from its constraint.

[0068] Using the above technical solution, the detection unit, through the cooperation of the thermal expansion ring 11, the limiting rod 7, the return spring 8, and the heat-conducting column 12, achieves automatic response of the switching seat 6 to temperature changes. The thermal expansion ring 11 expands when heated, driving the limiting rod 7 to retract into the detection groove, thereby releasing the restriction on the switching seat 6 and ensuring that the switching seat 6 can rotate rapidly and disconnect the electrical connection when overheated. This detection unit can not only monitor the temperature changes of the battery cells in real time, but also automatically trigger a protection mechanism when the temperature is too high, preventing electrical equipment from malfunctioning or causing fires due to overheating, thus ensuring the stability and reliability of the equipment.

[0069] In one embodiment of this application, the movable seat 2 is provided with a synchronization groove, and the connecting block 16 is provided with a synchronization rod 15. The synchronization rod 15 is inserted into the synchronization groove so as to drive the movable seat 2 to rotate when the switching seat 6 rotates.

[0070] Specifically, the movable seat 2 is provided with a synchronization groove, and the connecting block 16 is provided with a synchronization rod 15, which is inserted into the synchronization groove. The cooperative design of the synchronization rod 15 and the synchronization groove allows the movable seat 2 to rotate together when the switching seat 6 rotates. Specifically, when the switching seat 6 rotates under the action of the drive component, the synchronization rod 15, through its insertion into the synchronization groove, generates force transmission, transmitting the rotational motion to the movable seat 2, causing the movable seat 2 to rotate as well. The rotation of the movable seat 2 is synchronized with the rotation of the switching seat 6, ensuring that the movements of the switching seat 6 and the movable seat 2 are coordinated, thereby optimizing the disconnection process of the electrical connection and avoiding poor contact or short circuits caused by asynchrony.

[0071] By employing the above technical solution, the cooperation between the synchronizing rod 15 and the synchronizing groove enables the switching seat 6 and the movable seat 2 to rotate synchronously. This structure ensures that when the switching seat 6 rotates, the movable seat 2 moves synchronously with it, guaranteeing a smooth and reliable disconnection process for the entire electrical connection. Simultaneously, the synchronous rotation design avoids mechanical impact or jamming caused by asynchronous rotation of the movable seat 2, further improving the stability and safety of the wiring connector.

[0072] In one embodiment of this application, a semi-circular groove is provided on the inner sidewall of the assembly space, and a pressure block 18 that can slide in the semi-circular groove is connected to the drive plate 14. A miniature pressure rod 20 for detecting the position of the pressure block 18 is provided at the bottom of the semi-circular groove.

[0073] Specifically, a semi-circular groove is provided on the inner wall of the assembly space. A pressure block 18, which can slide within the semi-circular groove, is connected to the drive plate 14. A miniature pressure rod 20 for detecting the position of the pressure block 18 is provided at the bottom of the semi-circular groove. The pressure block 18, fixedly connected to the drive plate 14, can slide along the semi-circular groove as the drive plate 14 slides. The design of the semi-circular groove allows the pressure block 18 to move along a specific trajectory, thereby contacting the miniature pressure rod 20. The function of the miniature pressure rod 20 is to monitor the position of the pressure block 18. When the pressure block 18 slides to a certain position, the miniature pressure rod 20 can sense the pressure of the pressure block 18 and trigger an electrical signal based on its position. The triggered electrical signal can be used to indicate the working status of the wiring connector or for an alarm system to remind operators of abnormal conditions such as overheating.

[0074] By adopting the above technical solution, the cooperative design of the semi-circular slide groove and the pressure block 18 allows the drive plate 14 to slide smoothly and precisely during operation, driving the pressure block 18 to contact the miniature pressure rod 20, thereby monitoring the sliding position of the pressure block 18. Through the detection function of the miniature pressure rod 20, the positional change of the pressure block 18 can be sensed in real time, providing data support for equipment safety monitoring. In the event of overheating or other abnormalities, the interaction between the pressure block 18 and the miniature pressure rod 20 can promptly provide feedback on the equipment status and trigger an alarm.

[0075] like Figure 7 As shown, in one embodiment of this application, an indicator light 21 is provided on the outer wall of the assembly space, and a miniature pressure rod 20 is electrically connected to the indicator light 21. When the pressure block 18 contacts the miniature pressure rod 20, the indicator light 21 is lit.

[0076] Specifically, the miniature pressure rod 20 is electrically connected to the indicator light 21. When the pressure block 18 slides within the semi-circular groove and contacts the miniature pressure rod 20, the miniature pressure rod 20 is subjected to pressure and displaced, thereby triggering an electrical signal to illuminate the indicator light 21. The indicator light 21 illuminates to indicate to the operator that the wiring connector is in an abnormal state, which indicates that the battery cell is overheating, reminding personnel to check or maintain it promptly.

[0077] By adopting the above technical solution, the design of the indicator light 21 and the miniature pressure rod 20 allows for an intuitive fault alarm by immediately illuminating the indicator light 21 when the pressure block 18 contacts the miniature pressure rod 20. This function effectively improves the safety of the wiring connector, enabling operators to take immediate action when abnormal conditions such as overheating occur, thereby preventing more serious electrical faults or fire accidents.

[0078] like Figure 7 As shown, in one embodiment of this application, the first end of the fixed seat 1 is provided with a limiting ring 22, and the switching seat 6 is rotatably disposed inside the limiting ring 22.

[0079] Specifically, the first end of the fixed base 1 is provided with a limiting ring 22, and the switching base 6 is rotatably disposed inside the limiting ring 22. The function of the limiting ring 22 is to provide support and restrict the rotation of the switching base 6, ensuring that the switching base 6 can rotate stably and accurately during operation, and preventing its rotation from exceeding the predetermined angle range. By being disposed inside the limiting ring 22, the switching base 6 can rotate under the constraint of the limiting ring 22, and the rotation angle is effectively limited, avoiding the risk of abnormal electrical connection or poor contact due to excessive rotation.

[0080] By adopting the above technical solution, the limiting ring 22 provides the necessary support and constraint for the rotation of the switching seat 6, enabling the switching seat 6 to accurately and stably disconnect the electrical connection under overheating conditions, thus ensuring electrical safety. Through the structural design of the limiting ring 22, the rotation of the switching seat 6 is effectively restricted, which not only enhances the stability of the equipment but also ensures the rotation angle and operational reliability of the switching seat 6.

[0081] In one embodiment of this application, the arc angle of the semi-arc chute is set to 90 degrees, and the rotation angle of the switching seat 6 is limited to 90 degrees.

[0082] Specifically, the arc angle of the semi-circular slide is set to 90 degrees, and the rotation angle of the switching seat 6 is limited to 90 degrees. The 90-degree arc angle design of the semi-circular slide ensures that the rotation range of the switching seat 6 is precisely limited during rotation, thereby ensuring reliable disconnection of the electrical connection in the event of overheating. This prevents misoperation or poor contact due to excessive rotation angle, ensuring the safety and stability of the electrical connector.

[0083] By adopting the above technical solution, and setting the arc angle of the semi-circular slide to 90 degrees, the rotation angle of the switching seat 6 is limited to within 90 degrees, enabling the switching seat 6 to accurately disconnect the electrical connection within a predetermined angle. This not only ensures that the switching seat 6 can stably disconnect the circuit when overheated, but also avoids mechanical damage or electrical failures caused by excessive rotation angles, thereby improving the safety and reliability of the wiring connector.

[0084] like Figure 8 As shown, this application also discloses a distribution box, including a box body, on which a wiring connector with adaptive protection function as described in any of the above claims is provided.

[0085] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model.
