Description

Technical Field

[0001] This utility model belongs to the field of power wiring technology, and specifically relates to a junction box. Background Technology

[0002] With the rapid development of the automotive industry and the continuous improvement of various testing requirements, power cables used in testing are now equipped with connectors. Depending on the application location, these connectors are mainly divided into two types: dedicated plug-in connectors and DT copper lugs. For DT copper lug connectors, the traditional connection method is a bolt connection followed by wrapping with insulating tape. This connection method has many problems, seriously affecting the safety and efficiency of the test.

[0003] From a safety perspective, changes in ambient temperature and humidity significantly affect insulating tape. In high-temperature environments, the adhesive strength of the tape decreases, making it prone to deformation and peeling; while in low-temperature environments, the tape becomes brittle, also increasing the risk of detachment. Furthermore, frequent temperature and humidity changes can cause condensation on surfaces. If the insulating tape at the joint ages, peels, or detaches, exposing the connection point, it can easily lead to short circuits, electrical leaks, and other dangerous situations upon contact with water. This could not only damage testing equipment but also threaten the lives of testing personnel.

[0004] From an efficiency standpoint, the traditional method of bolting and wrapping with insulating tape is cumbersome. During testing, frequent cable connections and disconnections are required when moving the cable up and down the testing platform, necessitating the tightening and loosening of bolts and the wrapping and unwrapping of insulating tape each time. This undoubtedly increases preparation time and operational difficulty, reducing testing efficiency. Moreover, after repeated operations, bolts may loosen, and the insulation performance of the insulating tape may gradually decline, requiring repeated inspection and maintenance, further consuming manpower and time costs. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies where traditional copper lugs are fixed with bolts and wrapped with tape during wiring. These issues arise because the adhesive strength of the insulating tape decreases with temperature changes, increasing the risk of detachment. Furthermore, frequent temperature and humidity fluctuations can cause condensation on surfaces. Once the insulating tape at the joint ages, peels, or falls off, exposing the connection point, it can easily lead to short circuits and electrical leaks when exposed to water. This can damage testing equipment and threaten the safety of testing personnel. The invention provides a junction box design to solve these problems.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A junction box includes a junction box body, a temperature and humidity control box, and a power module for supplying power to the entire junction box. The junction box body includes a lower shell and an upper shell that is matched with the lower shell. A crimping control box and several copper busbars arranged side by side are provided on the lower shell at both ends of each copper busbar. A first wiring port is provided on the lower shell at the corresponding position of the upper shell. A fastening mechanism is provided around the first and second wiring ports. A crimping mechanism is provided on the upper shell above both ends of each copper busbar. The crimping mechanism is connected to the output end of a gas temperature and humidity treatment mechanism inside the temperature and humidity control box through a drive air supply pipe that passes through the crimping control box. The input end of the gas temperature and humidity treatment mechanism is connected to the atmosphere. A corresponding infrared detection element is provided on one side of each crimping mechanism. The output end of the infrared detection element is connected to the crimping mechanism and the crimping control box. The crimping control box is communicatively connected to the temperature and humidity control box.

[0008] Further improvements to this technical solution include a crimping mechanism comprising a cylinder and a moving insulating block. One end of the cylinder is fixed to the upper housing, and the moving insulating block is fixed to the end of the cylinder away from the upper housing. A bayonet is provided on the moving insulating block near the second wiring port. An air supply port and a communication port are provided on the side of the cylinder near the copper busbar. The air supply port is connected to the drive air supply pipe, and the communication port is connected to the output end of the infrared detection element.

[0009] A further improvement to this technical solution is that the crimping control box includes a first housing and a microprocessor disposed within the first housing. A touch screen is disposed on the top of the first housing, the touch screen is connected to the microprocessor, and an infrared detection element is connected to the input terminal of the microprocessor.

[0010] A further improvement to this technical solution is that a transparent viewing window is provided on the upper casing above the touch screen.

[0011] Further improvements to this technical solution include an air intake grille and an exhaust grille located on the side of the first housing near the copper busbar. The air intake grille is connected to the output end of the gas temperature and humidity treatment mechanism inside the temperature and humidity control box via an air intake pipe that passes through the first housing. The exhaust grille is connected to the gas temperature and humidity treatment mechanism inside the temperature and humidity control box via an exhaust pipe that passes through the first housing.

[0012] Further improvements to this technical solution include an insulating layer between the copper busbar and the lower housing, an insulating rubber partition between two adjacent copper busbars, and a waterproof rubber ring at the connection between the upper and lower housings.

[0013] Further improvements to this technical solution include a fastening mechanism comprising two frustum-shaped sleeves, which are fitted around the first and second terminals, and clamps are fitted around the sleeves.

[0014] Further improvements to this technical solution include a temperature and humidity control box comprising a second chamber, a touch-screen computer mounted on the second chamber, an air vent mounted on the second chamber, and a temperature and humidity processing mechanism mounted inside the second chamber comprising a processing box and an air pump mounted on the processing box near the air vent. The processing box contains a dehumidifier and a heating element, all of which are connected to the touch-screen computer.

[0015] A further improvement to this technical solution is that the second housing is equipped with a drain outlet connected to the dehumidifier.

[0016] Further improvements to this technical solution include the addition of a start / stop button and an emergency stop button on the second housing, both of which are connected to a touch-screen computer.

[0017] The beneficial effects of this utility model are as follows:

[0018] Reduced risk of exposed connectors: In traditional connection methods, insulating tape is prone to aging, peeling, and detachment due to temperature and humidity changes, leading to exposed connectors. Exposure to water can cause short circuits, electrical leaks, and other hazards. This junction box, however, uses a crimping mechanism to securely crimp cable connectors, and a fastening mechanism further ensures stable connections, significantly reducing the risk of connector exposure. Furthermore, the junction box's temperature and humidity control box regulates the internal temperature and humidity environment, minimizing the impact of drastic temperature and humidity fluctuations on cable connectors.

[0019] Preventing leakage and phase-to-phase short circuits: The insulation layer between the copper busbar and the lower housing effectively prevents current from being conducted to the lower housing, reducing the probability of leakage accidents and avoiding energy waste and electric shock hazards. The insulating rubber partition between adjacent copper busbars reliably separates different copper busbars, preventing phase-to-phase short circuits caused by external forces, high-temperature deformation, etc., and avoiding damage to electrical components and serious accidents such as fires.

[0020] To prevent condensation hazards: The air intake and exhaust grilles of the first enclosure work in conjunction with the temperature and humidity control box to introduce temperature- and humidity-treated gas, increasing the temperature and dryness of the air inside the enclosure, and expelling moisture, effectively preventing condensation. Condensation can reduce the insulation performance of electrical equipment and cause accidents such as short circuits. This design ensures the safe operation of the equipment.

[0021] Preventing moisture intrusion: The waterproof rubber ring at the connection between the upper and lower housings forms a reliable waterproof barrier, and the fastening mechanism also prevents external moisture from entering the junction box, reducing safety hazards such as short circuits and leakage caused by moisture intrusion and improving wiring safety.

[0022] Furthermore, the design principle of this utility model is reliable, the structure is simple, and it has a very wide range of application prospects.

[0023] It is evident that this utility model has outstanding substantive features and significant progress compared with the prior art, and the beneficial effects of its implementation are also obvious. Attached Figure Description

Detailed Implementation

[0031] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0032] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0033] The key terms appearing in this utility model are explained below.

[0034] DT copper lugs are connectors used to connect cables to electrical equipment, typically made of copper. Shaped like a nose, one end has an opening to insert the cable, which is then securely connected via crimping or welding. The other end has a hole for connecting to electrical equipment using bolts or similar methods. They are widely used in electrical installation, power engineering, and other fields.

[0035] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, this utility model provides a junction box, including a junction box body 100, a temperature and humidity control box, and a power module for supplying power to the entire junction box. The junction box body 100 includes a lower housing 110 and an upper housing 120 that is matched with the lower housing 110. The lower housing 110 is provided with a crimp control box and several copper busbars 140 arranged side by side. Each copper busbar 140 has a first wiring port 111 at both ends of the lower housing 110, and a second wiring port 121 is provided at the corresponding position of the upper housing 120. Fastening devices are provided around the first wiring port 111 and the second wiring port 121. The mechanism includes a crimping mechanism on the upper housing 120 above both ends of each copper busbar 140. The crimping mechanism is connected to the output end of the gas temperature and humidity treatment mechanism inside the temperature and humidity control box via a drive air supply pipe that passes through the crimping control box. The input end of the gas temperature and humidity treatment mechanism is connected to the atmosphere. Each crimping mechanism has a corresponding infrared detection element 163 on one side. The output end of the infrared detection element 163 is connected to the crimping mechanism and the crimping control box. The crimping control box is communicatively connected to the temperature and humidity control box. The crimping control box and the temperature and humidity control box communicate via a CAN bus.

[0036] Traditional DT copper lug connectors use bolts and insulating tape for connection. However, the tape is prone to aging, peeling, and detachment under varying temperature and humidity, leading to exposed connectors and potential hazards. This junction box, on the other hand, features a crimping mechanism connected to a temperature and humidity control chamber via a drive air supply pipe. The control chamber regulates the temperature and humidity environment within the junction box, reducing the impact of drastic temperature and humidity changes on the cable connectors. Simultaneously, the crimping mechanism securely crimps the cable connectors, further ensuring connection stability in conjunction with the fastening mechanism. This reduces the risk of connector exposure and effectively prevents short circuits, electrical leaks, and other safety accidents caused by exposed connectors exposed to water, thus protecting the safety of testing equipment and personnel.

[0037] Specifically, the crimping mechanism includes a cylinder 161 and a moving insulating block 162. One end of the cylinder 161 is fixed to the upper housing 120, and the moving insulating block 162 is fixed to the end of the cylinder 161 away from the upper housing 120. A locking mechanism is provided on the moving insulating block 162 near the second wiring port 121. An air supply port 1611 and a communication port 1612 are provided on the side of the cylinder 161 near the copper busbar 140. The air supply port 1611 is connected to a drive air supply pipe, and the communication port 1612 is connected to the output terminal of the infrared detection element 163. The cylinder 161 drives the moving insulating block 162 to crimp the cable connector. This crimping method is more robust than traditional bolt connections, effectively resisting the effects of temperature and humidity changes, vibration, and other factors on the connection, ensuring a stable connection between the cable and the copper busbar 140, reducing contact resistance, and minimizing problems such as overheating and arcing caused by loose connections, thus improving the reliability of the entire electrical system. In addition, when the infrared detection element 163 malfunctions, the tester can operate (including operate up or down) the corresponding crimping mechanism via the crimping button installed on the crimping control box.

[0038] The crimping control box includes a first housing 131 and a microprocessor disposed within the first housing 131. A touch screen 1312 is disposed on the top of the first housing 131. The touch screen 1312 is connected to the microprocessor, and an infrared detection element 163 is connected to the input terminal of the microprocessor.

[0039] To facilitate real-time monitoring of the junction box's operational status by testing personnel, the junction box body 100 is equipped with a temperature and humidity sensor, a pressure sensor, and a voltage and current detection module mounted on the copper busbars 140. These sensors are all connected to the input of a microprocessor, and the values ​​are displayed via a touchscreen 1312 connected to the microprocessor. Furthermore, a transparent observation window 122 (a transparent, touchable observation window) is provided on the upper housing 120 above the touchscreen 1312, protecting the touchscreen 1312 while allowing technicians to clearly observe the measured values. When detecting voltage, the copper busbars 140 are tested in pairs, but the wiring cables of the paired copper busbars 140 are not connected. Specifically, one side of the upper surface of each paired copper busbar 140 is connected to the current detection microprocessor within its corresponding voltage and current module to detect current; the other side of the upper surface is connected to its corresponding voltage detection microprocessor. The paired voltage and current modules are connected via a wiring harness to detect voltage.

[0040] In addition, an air inlet grille and an exhaust grille 1311 are provided on the side of the first housing 131 near the copper busbar 140. The air inlet grille is connected to the output end of the gas temperature and humidity treatment mechanism inside the temperature and humidity control box through an air inlet pipe passing through the first housing 131. The exhaust grille 1311 is connected to the gas temperature and humidity treatment mechanism inside the temperature and humidity control box through an exhaust pipe passing through the first housing 131. The gas temperature and humidity treatment mechanism inside the temperature and humidity control box can perform dehumidification, heating, and other operations on the air to adjust it to a suitable temperature and humidity state. The treated gas enters the first housing 131 through the air inlet pipe and the air inlet grille, forming a stable temperature and humidity environment inside the first housing 131. This helps to avoid adverse effects on the copper busbar 140 and the cable connectors connected to the copper busbar 140 due to drastic changes in external temperature and humidity. Under conditions of large temperature and humidity changes, condensation may occur inside the first housing 131. Condensation can reduce the insulation performance of electrical equipment and even cause serious safety accidents such as short circuits. Introducing temperature- and humidity-treated gas through the air inlet grille increases the temperature and dryness of the air inside the first enclosure 131, effectively preventing condensation. Simultaneously, the exhaust grille 1311 removes moisture from the enclosure, further reducing the risk of condensation and ensuring safe equipment operation. Furthermore, a stable temperature and humidity environment helps reduce the contact resistance between the copper busbar 140 and the cable connector. Under suitable temperature and humidity conditions, an oxide layer is less likely to form on the surface of the copper busbar 140, and the metal parts of the cable connector maintain good conductivity. By continuously supplying gas with suitable temperature and humidity, the increase in resistance caused by environmental factors is reduced, thereby reducing power loss and improving the efficiency of the entire electrical system.

[0041] Furthermore, an insulating layer 171 is provided between the copper busbar 140 and the lower housing 110, and an insulating rubber partition 172 is provided between two adjacent copper busbars 140. A waterproof rubber ring is provided at the connection between the upper housing 120 and the lower housing 110 (the waterproof rubber ring has good sealing performance and can form a reliable waterproof barrier at the connection, preventing moisture intrusion, protecting the electrical equipment in the junction box from the influence of a humid environment, and ensuring that the equipment can operate normally in harsh environments). Specifically, the insulating layer 171 provided between the copper busbar 140 and the lower housing 110 can effectively prevent current from being conducted from the copper busbar 140 to the lower housing 110. During the use of the junction box, the copper busbar 140 usually carries a certain voltage and current. Without the insulating layer 171, if the copper busbar 140 and the lower housing 110 accidentally come into contact or if the distance between them becomes too small due to vibration or other factors, leakage may occur. This will not only waste electrical energy but may also pose a risk of electric shock to nearby operators and equipment. The presence of insulation layer 171 defines a safe path for current conduction, greatly reducing the probability of leakage accidents and ensuring the safety of personnel and equipment. The insulating rubber partition 172 between adjacent copper busbars 140 serves to isolate different copper busbars 140. In an electrical system, different copper busbars 140 may carry currents of different phases. Without the insulating rubber partition 172, when copper busbars 140 are subjected to external pressure, vibration, or slight deformation under high temperature, adjacent copper busbars 140 may come into contact, causing a phase-to-phase short circuit. A phase-to-phase short circuit generates a huge short-circuit current, which may damage electrical components in the junction box and even cause serious accidents such as fires. The insulating rubber partition 172 has excellent insulation properties, reliably separating adjacent copper busbars 140, preventing phase-to-phase short circuits, and ensuring the stable operation of the electrical system. In addition to their insulation function, insulation layer 171 and insulating rubber partition 172 can also reduce electromagnetic interference between copper busbars 140 to a certain extent. When current passes through a copper busbar 140, an electromagnetic field is generated around it. The electromagnetic fields between adjacent copper busbars 140 may interfere with each other, disrupting the normal transmission of electrical signals and causing malfunctions or performance degradation in electrical equipment. Insulating materials can shield and isolate electromagnetic fields, reducing the degree of electromagnetic interference, ensuring the normal operation of electrical equipment within the junction box, and improving the reliability of the entire electrical system. The insulating layer 171 and the insulating rubber partition 172 also enhance the stability of the junction box in terms of physical structure. They fill the gaps between the copper busbars 140 and the lower housing 110, as well as between adjacent copper busbars 140, making the installation of the copper busbars 140 more secure and reducing displacement or loosening caused by vibration or external impact. This helps maintain the stability of the electrical connection, avoiding problems such as poor contact and overheating caused by loose connections, further improving the reliability and service life of the equipment.

[0042] Furthermore, the fastening mechanism includes two frustum-shaped sleeves 151, which are fitted around the first connector 111 and the second connector 121. A clamp 152 is fitted around the outer edge of each sleeve. In actual operation, the two frustum-shaped sleeves 151 are first precisely fitted around the outer edge of the first connector 111 and the second connector 121. These two frustum-shaped sleeves 151 fit perfectly, tightly enclosing the first connector 111 and the second connector 121, ensuring a tight connection. Next, the clamp 152 is carefully fitted around the outer edge of the two sleeves and moderately tightened. The clamp 152 provides a strong binding force for the connection between the interface and the sleeves, further enhancing the tightness of the connection.

[0043] This unique fastening method offers significant advantages. Firstly, it greatly enhances the reliability of the wiring. In complex operating environments, whether facing minor vibrations, daily pulling, or other external interference, the wiring remains secure, effectively preventing problems such as poor contact caused by loosening, and ensuring the stability and continuity of power transmission. Secondly, it constructs a reliable waterproof barrier, effectively preventing external moisture from entering the junction box. Moisture intrusion can cause a series of safety hazards, such as short circuits and leakage, while this fastening mechanism minimizes these risks, significantly improving wiring safety and providing strong protection for the stable operation of the entire electrical system.

[0044] The temperature and humidity control box includes a second housing 210, on which a touch-screen computer 211 is installed. An air vent 212 is also located on the second housing 210. The temperature and humidity processing mechanism inside the second housing 210 includes a processing box and an air pump located near the air vent 212. The processing box contains a dehumidifier and a heating element, all of which are connected to the touch-screen computer 211. The gas temperature and humidity processing mechanism within the control box can adjust the temperature and humidity within the junction box as needed (when the microprocessor determines that the received temperature and humidity sensor values ​​exceed a preset threshold, the touch-screen computer 211 activates the gas temperature and humidity processing mechanism). This is achieved by starting the dehumidifier and heating element at a preset power, inputting the heated and dehumidified air into the junction box body 100 to regulate temperature and humidity. The input end of the gas temperature and humidity processing mechanism is connected to the atmosphere, allowing it to draw in outside air. After processing by the dehumidifier and heating element, the air with suitable temperature and humidity is delivered to the junction box via a drive air supply pipe. This allows the junction box to maintain a relatively stable temperature and humidity environment, effectively reducing the possibility of condensation on the surfaces of objects inside the junction box, avoiding adverse effects on cable joints and electrical connections caused by changes in external temperature and humidity, and improving the adaptability of the junction box under different temperature and humidity conditions.

[0045] For the first connection port 111 and the second connection port 121 for connecting the copper lug, this utility model provides a plug 153, which is sleeved around the first connection port 111 and the second connection port 121.

[0046] During operation, a dehumidifier condenses moisture in the air into liquid water. If this water is not drained promptly, it will accumulate inside the dehumidifier or in the second housing 210. Accumulated water can damage the dehumidifier's electrical components, causing short circuits, corrosion of metal parts, etc., thus affecting the dehumidifier's normal operation and lifespan. Therefore, the second housing 210 is equipped with a drain outlet 213 connected to the dehumidifier. The drain outlet 213 ensures that the water produced by the dehumidifier can be drained from the second housing 210 in a timely manner, avoiding the potential harm of accumulated water and ensuring the dehumidifier can operate continuously and stably, guaranteeing the effectiveness of its dehumidification function. If the water produced by the dehumidifier cannot be drained promptly, the water accumulated in the second housing 210 will evaporate back into the air, causing the humidity inside the junction box to rise, resulting in a humidity rebound. This contradicts the dehumidifier's initial purpose of reducing humidity, making it impossible for the temperature and humidity environment inside the junction box to reach an ideal state. The presence of drain outlet 213 prevents this from happening, ensuring that the dehumidifier can continuously reduce the humidity inside the junction box, creating a dry and stable operating environment for electrical equipment. Excessive humidity inside the junction box easily leads to condensation, which can severely affect the insulation performance of electrical equipment and may cause safety accidents such as leakage and short circuits. Timely drainage of water produced by the dehumidifier through drain outlet 213 effectively controls the humidity inside the junction box, reduces the risk of condensation, and ensures the safe operation of electrical equipment.

[0047] Finally, the second enclosure 210 is also equipped with a power interface 214, a start / stop button 215, and an emergency stop button 216, both of which are connected to the touchscreen computer 211. The emergency stop button 216 plays a crucial role in emergencies. When a sudden situation occurs in the junction box, such as a short circuit, leakage, or abnormally high temperature, that may endanger equipment safety or personnel lives, the operator can immediately press the emergency stop button 216. This button is directly connected to the touchscreen computer 211 and can quickly transmit a signal to the touchscreen computer 211, thereby rapidly cutting off the operation of the temperature and humidity control box, preventing further escalation of the accident, and maximizing the safety of equipment and personnel.

[0048] The working principle of the junction box provided by this utility model is as follows: Before starting, the junction box body is connected to the temperature and humidity control box through the wiring harness and pipeline. After confirming that the connection is complete, the start / stop button 215 is pressed on the temperature and humidity control box to start the temperature and humidity control box and the junction box body. The copper lug of the cable to be connected is inserted into the slot of the moving insulating block 162. The infrared detection element 163 corresponding to the moving insulating block 162 sends the detected signal to the microprocessor and the corresponding cylinder 161, triggering the temperature and humidity processing mechanism to supply air to the cylinder 161, so that the cylinder 161 pushes the moving insulating block 162 downward, pressing the copper lug onto the copper busbar 140, realizing quick wiring.

[0049] The above description of the disclosed embodiments enables those skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
