Description

Technical Field

[0001] This utility model relates to the field of emergency power supply connection technology, and in particular to a low-voltage emergency access device for an emergency power generation vehicle. Background Technology

[0002] In power emergency response systems, emergency generator vehicles are core equipment for rapidly restoring temporary power to critical facilities. The reliability, convenience, and safety of the connection between their low-voltage output (typically 400V or 690V) and the receiving facilities directly determine the timeliness and stability of emergency power supply. Currently, the mainstream connection methods mostly use standard industrial plugs and sockets or simple copper-aluminum terminal blocks.

[0003] However, in complex application scenarios such as disaster relief, outdoor emergency repairs, and large-scale events, existing connection devices have significant performance shortcomings: First, the mechanical protection of cables is weak. Under frequent dragging, bending, and external impact, the junction between the cable and the connector shell is prone to surface cracking and core wire fatigue fracture. Traditional heat shrink tubing or tape wrapping methods have poor weather resistance, cannot resist oil corrosion and ultraviolet aging, and lack tensile strength. Second, the insertion stability is insufficient. Conventional smooth surface contact structures are prone to loosening in vibration environments (such as the operation of generator vehicles or the passage of engineering vehicles), which once caused a power outage during a live broadcast at a sports center due to the accidental detachment of a connector. The lack of sealing allows sand and rainwater to enter the terminal area, inducing increased contact resistance or even short circuits and fires. Therefore, a low-voltage emergency access device for emergency generator vehicles is proposed to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to at least solve one of the aforementioned technical defects.

[0005] Therefore, one objective of this utility model is to provide a low-voltage emergency access device for an emergency power generation vehicle, in order to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0006] To achieve the above objectives, one embodiment of this utility model provides a low-voltage emergency access device for an emergency power generation vehicle, including a housing and a cable. The cable is fixedly connected to the base of the housing, and a connector is fixedly connected to the upper and lower parts of the base of the housing. Clamps are fixedly connected to both sides of the connector by rivets. A protective layer is wrapped around the outer surface of the connection between the cable and the housing, and the clamps tighten the protective layer from the outside.

[0007] The outer end of the cable is fixedly connected to the emergency power generation vehicle, and a terminal is fixedly connected inside the outer casing;

[0008] A jacket is fixedly connected to the outer surface of the terminal, and a foolproof notch is provided on the jacket.

[0009] A gap is provided between the outer jacket and the outer shell, and an anti-slip layer is fixedly connected to the inner side of the outer shell. The outer surface of the anti-slip layer is wavy.

[0010] Preferably, in any of the above solutions, the outer casing is made of plastic, and the cable is electrically connected to the terminal.

[0011] The above technical solution is adopted: the low-voltage emergency access device of this emergency power generation vehicle is the low-voltage emergency connector of the emergency power generation vehicle.

[0012] This includes the main structural components such as the outer shell, cables, terminals, jacket, protective layer, connectors, and clamps.

[0013] The cable connects to the emergency power generation vehicle at its outer end, and the cable is electrically connected to the terminal. The outer jacket protects the terminal, and the foolproof notch ensures the correct insertion and positioning of the terminal. The protective layer protects the connection between the cable and the outer shell to prevent the connection from breaking.

[0014] The core structure consists of: rivets, clamps, protective layer, outer jacket, outer shell, and a wavy anti-slip layer.

[0015] A protective layer is wrapped around the connection between the outer shell and the cable. A connector is pre-installed at the base of the outer shell. The connector is fixed to the two sides by rivets and clamps. The clamps hold the outer surface of the protective layer tightly, so that the protective layer can be firmly bonded to the outer surface of the connection between the outer shell and the cable, preventing the gap from breaking. This solves the problem of easy damage at the base of the cable and extends the service life of the device.

[0016] An outer sleeve is fixedly connected to the outer surface of the terminal, protecting the terminal. A gap is provided between the outer sleeve and the outer shell. When connecting to a load, the load connector is inserted into this gap. The anti-slip layer is wavy, providing high friction with the load connector, ensuring a stable and secure connection, preventing accidental loosening, and providing strong shock and tensile resistance. It also has a certain degree of sealing performance.

[0017] Preferably, in any of the above solutions, the rivet passes through both ends of the joint and the clamp, and the protective layer is made of neoprene rubber.

[0018] The above technical solution is adopted. The device structure consists of: outer shell: the main structural component, which is usually made of plastic to ensure insulation and portability.

[0019] Cable: Its root (the end closest to the housing) is fixedly connected to the housing. The outer end of the cable is used to fixally connect to the low-voltage output port of the emergency generator vehicle, and its internal conductor is electrically connected to the terminals inside the housing.

[0020] Protective layer: The outer surface covering the connection between the cable and the outer casing. This protective layer is preferably made of elastic, abrasion-resistant, and weather-resistant neoprene rubber, providing additional protection and stress cushioning. The thickness of the protective layer can be designed according to the specific application requirements.

[0021] Connectors and clamps: Connector structures are fixedly connected above and below the root area of ​​the housing (near the protective layer). Clamps are fixedly connected to both sides of the connectors using special rivets (such as rivets). After installation, the clamps tightly grip the protective layer from the outside, forming a strong mechanical restraint.

[0022] Terminals: Fixedly connected inside the housing. Terminals are the core components for achieving electrical connections, and their specific shape (such as pins or sockets) is designed according to the functional role of the device (male or female). Several honeycomb-shaped holes are formed on the terminal; this design helps dissipate heat, reduces temperature rise under high current, and improves current carrying capacity and reliability.

[0023] Outer sleeve: Securely attached to the outer surface of the terminal, providing physical and insulating protection. The outer sleeve is preferably made of PC (polycarbonate) material, which possesses high strength, high toughness, flame retardancy, and good insulation properties. The outer sleeve has at least one foolproof notch, ensuring that the device can only be inserted into the corresponding load connector in the single correct orientation and angle, effectively preventing reverse insertion or misinsertion.

[0024] Anti-slip layer: Located within the annular gap formed between the outer casing and the inner wall of the outer shell. The anti-slip layer is a flexible, friction-resistant material, preferably rubber. Its outer surface is processed into a wavy shape (such as corrugated, serrated, or other surface textures that increase the coefficient of friction). The anti-slip layer is fixedly attached to the inner wall of the outer shell by a fixing structure (such as adhesive or clips).

[0025] Preferably, in any of the above solutions, the thickness of the protective layer is such that the terminal has a plurality of honeycomb-shaped holes.

[0026] Preferably, of any of the above solutions, the outer cover is made of PC and the anti-slip layer is flexible.

[0027] Preferably, in any of the above embodiments, the anti-slip layer is made of rubber and is located in the gap between the outer jacket and the outer shell.

[0028] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0029] The low-voltage emergency access device of this emergency generator vehicle is designed with a combination of rivets, clamps, protective layers, outer jackets, outer shells, and a corrugated anti-slip layer.

[0030] A protective layer is wrapped around the connection between the outer shell and the cable. A connector is pre-installed at the base of the outer shell. The connector is fixed to the two sides by rivets and clamps. The clamps hold the outer surface of the protective layer tightly, so that the protective layer can be firmly bonded to the outer surface of the connection between the outer shell and the cable, preventing the gap from breaking. This solves the problem of easy damage at the base of the cable and extends the service life of the device.

[0031] A jacket is fixedly connected to the outer surface of the terminal, protecting the terminal. A gap is provided between the jacket and the outer shell. When aligning with the load, the load connector is inserted into this gap. The anti-slip layer is wavy, providing high friction with the load connector, ensuring a stable and secure connection, preventing accidental loosening, and providing strong shock and tensile resistance. The tight compression contact between the anti-slip layer and the outer wall of the load connector creates a stable radial seal, improving the protection level (such as dustproof and splashproof) and enhancing sealing performance.

The cable 2 is fixedly connected to the base of the shell 1, and a connector 3 is fixedly connected to the upper and lower parts of the base of the shell 1. The two sides of the connector 3 are fixedly connected to clamps 5 by rivets 4. A protective layer 6 is wrapped around the outer surface of the connection between the cable 2 and the shell 1, and the clamps 5 hold the protective layer 6 tightly from the outside.

[0045] Example 1: The outer shell 1 is made of plastic, and the cable 2 is electrically connected to the terminal 7. The rivet 4 passes through both ends of the connector 3 and the clamp 5. The protective layer 6 is made of neoprene rubber. The thickness of the protective layer 6 is [not specified]. The terminal 7 has several honeycomb-shaped holes. The outer jacket 8 is made of PC, and the anti-slip layer 10 is flexible. The anti-slip layer 10 is made of rubber and is located in the gap between the outer jacket 8 and the outer shell 1.

[0046] Example 2: The low-voltage emergency access device of this emergency power generation vehicle is the low-voltage emergency connector of the emergency power generation vehicle.

[0047] The main structural components include the outer shell 1, cable 2, terminal 7, outer jacket 8, protective layer 6, connector 3, and clamp 5.

[0048] The cable 2 is connected to the emergency power generation vehicle at its outer end. The cable 2 is electrically connected to the terminal 7. The outer jacket 8 protects the terminal 7. The foolproof notch 9 ensures the correct insertion and positioning of the terminal 7. The protective layer 6 protects the connection between the cable 2 and the outer shell 1 to prevent the connection from breaking.

[0049] Device structure composition: Outer shell 1: Main structural component, usually made of plastic to ensure insulation and lightness.

[0050] Cable 2: Its root (the end closest to housing 1) is fixedly connected to housing 1. The outer end of cable 2 is used to fixally connect to the low-voltage output port of the emergency generator vehicle, and its internal conductor is electrically connected to terminal 7 inside housing 1.

[0051] Protective layer 6: The outer surface covering the connection between cable 2 and outer shell 1. This protective layer 6 is preferably made of elastic, abrasion-resistant, and weather-resistant neoprene rubber, providing additional protection and stress cushioning. The thickness of the protective layer 6 can be designed according to the specific application requirements.

[0052] Connector 3 and clamp 5: Connector 3 is fixedly connected above and below the root area of ​​the outer casing 1 (near the protective layer 6). Clamp 5 is fixedly connected to both sides of connector 3 by special rivets 4 (such as rivets). After installation, clamp 5 tightly hugs the protective layer 6 from the outside, forming a strong mechanical restraint.

[0053] Terminal 7: Fixedly connected inside the housing 1. Terminal 7 is the core component for realizing electrical connection, and its specific shape (such as pin or socket) is designed according to the functional role of the device (male or female). Several honeycomb-shaped holes are formed on terminal 7. This design helps heat dissipation, reduces temperature rise under high current, and improves current carrying capacity and reliability.

[0054] Outer sleeve 8: Fixedly connected to the outer surface of terminal 7, providing physical and insulating protection for terminal 7. The outer sleeve 8 is preferably made of PC (polycarbonate) material with high strength, high toughness, flame retardancy, and good insulation properties. At least one foolproof notch 9 is provided on the outer sleeve 8, ensuring that the device can only be inserted into the corresponding load connector in the single correct direction and angle, effectively preventing reverse insertion or misinsertion.

[0055] Anti-slip layer 10: Set within the annular gap formed between the outer jacket 8 and the inner wall of the outer shell 1. The anti-slip layer 10 is a flexible, friction-resistant material layer, preferably rubber. Its outer surface is processed into a wavy shape (such as corrugated, serrated, or other surface textures that increase the coefficient of friction). The anti-slip layer 10 is fixedly connected to the inner wall of the outer shell 1 by a fixing structure (such as adhesive or snap-fit).

[0056] The working principle of this utility model is as follows:

[0057] Initial connection preparation:

[0058] Securely connect the outer end of cable 2 to the designated low-voltage output port of the emergency power generator.

[0059] Check that the protective layer 6 is intact and ensure that the clamp 5 is securely held in place by the rivet 4 at the connection between the cable 2 and the outer shell 1. This structural design is specifically designed to protect this vulnerable point, preventing the cable from breaking or cracking at the root (joint) due to repeated bending and stress during use or dragging, greatly improving the mechanical strength and durability of this area.

[0060] Check the cleanliness and integrity of terminal 7 and outer sleeve 8, and observe the position of the foolproof notch 9.

[0061] Connecting to load:

[0062] The operator holds the outer casing 1 and aligns the front end of the device (the side containing the outer casing 8, the anti-slip layer 10, and the terminal 7) with the corresponding low-voltage input connector of the target load device or power distribution port.

[0063] Positioning is achieved by using the foolproof notch 9 on the outer casing 8 to ensure that the device can only be inserted in the one correct orientation, thus avoiding electrical faults or damage caused by incorrect insertion.

[0064] Apply pressure to insert the mating ends of the device (outer casing 8 and inner terminal 7) into the cavity of the load connector.

[0065] A stable connection is formed:

[0066] During insertion, the outer wall of the load connector will enter the annular gap between the outer sleeve 8 and the inner wall of the outer shell 1.

[0067] The anti-slip layer 10 located within this gap is in close contact with the outer wall of the load connector. The flexible material of the anti-slip layer 10 and the wavy texture on its surface greatly increase the friction between the contact surfaces, thus forming a stable mechanical connection between the device and the load connector, effectively resisting loosening or shaking caused by external forces.

[0068] The tight compression contact between the anti-slip layer 10 (rubber material) and the outer wall of the load joint also forms a certain radial sealing effect, improving the protection level (such as dustproof and splashproof).

[0069] Meanwhile, terminal 7 inside the device achieves precise electrical engagement with the corresponding terminal inside the load connector, establishing an electrical path. The honeycomb-shaped perforation design on terminal 7 effectively increases the heat dissipation area when current flows, accelerating heat dissipation, ensuring the terminal operates within a safe temperature range, and improving high-current switching capacity and connection reliability.

[0070] Emergency power supply:

[0071] After the electrical and mechanical connections are established, the low-voltage power generated by the emergency power generation vehicle is transmitted through cable 2, and then transmitted through terminal 7, and finally safely and stably connected to the target load or network to realize the emergency power supply function.

[0072] Disconnect:

[0073] When the power supply is finished or needs to be disconnected, the operator can simply hold the outer casing 1 and overcome the frictional resistance provided by the anti-slip layer 10 to smoothly pull the device off the load connector. The protective layer 6 and the clamp 5 structure ensure that this operation will not damage the cable root connection.

[0074] Compared with the prior art, the present invention has the following advantages:

[0075] The low-voltage emergency access device of this emergency generator vehicle is configured through the cooperation of rivets 4, clamps 5, protective layers 6, outer jackets 8, outer shells 1, and a corrugated anti-slip layer 10.

[0076] A protective layer 6 is wrapped around the connection between the outer shell 1 and the cable 2. A connector 3 is pre-set at the root of the outer shell 1. The connector 3 is fixedly connected to the clamps 5 on both sides by rivets 4. The clamps 5 hold the outer surface of the protective layer 6 tightly, so that the protective layer 6 can be firmly combined with the outer surface of the connection between the outer shell 1 and the cable 2, preventing the opening from cracking, solving the problem of easy damage at the root of the cable 2, and extending the service life of the device.

[0077] A jacket 8 is fixedly connected to the outer surface of terminal 7, protecting terminal 7. A gap is provided between the jacket 8 and the outer shell 1. When connecting to the load gap, the load connector is inserted into this gap. The anti-slip layer 10 is wavy, providing high friction with the load connector, ensuring a stable and secure connection, preventing accidental loosening, and providing strong shock and tensile resistance. The tight compression contact between the anti-slip layer 10 and the outer wall of the load connector also forms a stable radial seal, improving the protection level (such as dustproof and splashproof) and enhancing sealing performance.
