Description

Technical Field

[0001] This utility model belongs to the field of power equipment technology, and in particular relates to a power high-voltage harness with an anti-interference shielding structure. Background Technology

[0002] High-voltage power harnesses with anti-interference shielding structures are core power transmission components suitable for high-voltage and high-current scenarios. They use stranded copper or copper alloy wires as the conductive core, covered with insulating layers, and integrated with a professional shielding structure to achieve electromagnetic compatibility protection. They are key components for ensuring stable power transmission and system safety in fields such as new energy vehicles and industrial equipment. Their core shielding design often employs a composite structure of "metal foil + braided layer." The aluminum foil layer primarily resists high-frequency interference, while the tinned copper wire braided layer targets low-frequency interference. Some high-end products also incorporate special materials such as permalloy layers to further optimize shielding effectiveness. Simultaneously, a coaxial structure design ensures that the magnetic field of the inner conductor is distributed concentrically, with the electric field ending at the shielding layer, blocking electromagnetic radiation leakage at its source. The shielding layer must achieve reliable 360° grounding through structures such as shielding rings and spring contacts to guide interference signals to the ground. Multiple grounding points are strictly prohibited to prevent induced interference. Ultimately, it must meet industry standards (such as ISO 14572) such as shielding attenuation ≥60dB and transfer impedance ≤31mΩ / m. This design ensures efficient transmission of high-voltage power, avoids electromagnetic radiation interference with surrounding electronic devices, and resists external interference signals, making it suitable for critical scenarios such as power transmission from battery to motor and interconnection of high-voltage equipment.

[0003] Because power supply high-voltage harnesses with anti-interference shielding structures use conventional plugs and sockets, when the power is first turned on, the live conductors are exposed, which is very dangerous when they come into contact with the human body and can easily cause electric sparks. This results in a relatively low safety factor for power supply high-voltage harnesses with anti-interference shielding structures using conventional plugs.

[0004] To address this issue, we propose a high-voltage power harness with an anti-interference shielding structure. Utility Model Content

[0005] The purpose of this invention is to solve the problem that the safety factor of a power high-voltage harness with an anti-interference shielding structure using a conventional plug is relatively low, and to propose a power high-voltage harness with an anti-interference shielding structure.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A high-voltage power harness with an anti-interference shielding structure includes a socket. A connecting rod is fixedly connected inside the socket. A movable stop is movably fitted around the connecting rod, and the movable stop is slidably installed inside the socket. A spring is fixedly connected to the outside of the socket. A plug is inserted into the socket, and the connecting rod is plugged into and electrically connected to the plug. The spring is engaged with the plug. A spring is movably fitted around the connecting rod, with one end fixedly connected to the socket and the other end fixedly connected to the movable stop. In the non-connected state, the movable stop blocks the connecting rod from contacting the human body. When the plug is inserted into the socket, the plug presses against the connecting rod, causing the movable stop to retract against the spring force, allowing the connecting rod to insert into the plug and mate with it. During the connection process, the conductor remains shielded internally, improving safety.

[0007] Preferably, the socket includes a base, on which a first high-voltage wiring harness body is fixedly connected. A movable stop is guided to slide using the inner wall of the base.

[0008] Preferably, the power receiving pole includes a pole body, a conductive plate is fixedly connected inside the pole body, the root of the pole body is fixedly connected to the inside of the base body, and the conductive plate is electrically connected to the first high-voltage wire harness body. The power receiving pole is electrically connected to the plug through the conductive plate.

[0009] Preferably, the movable stop includes a block with a hollowed-out sliding hole inside, into which the rod is slidably inserted. In the non-connected state, the block covers the rod; during connection, the plug and block are used to shield the conductive sheet.

[0010] Preferably, the plug includes a housing with a slot on its side. An elastic conductive sheet is fixedly connected inside the housing, and a second high-voltage wire harness body is fixedly connected to the housing. The elastic conductive sheet is electrically connected to the second high-voltage wire harness body, and the conductive sheet and the elastic conductive sheet are mated together. After the connector is inserted into the housing, the conductive sheet contacts the elastic conductive sheet, thus electrically connecting the connector to the plug.

[0011] Preferably, the spring clip includes a spring strip, the tail of which is fixedly connected to the base body, a button is fixedly connected to the outside of the spring strip, and a latching block is fixedly connected to the head of the spring strip. The latching block engages with a latching groove. The spring strip's elasticity acts on the latching block, keeping it within the latching groove. Pressing the button causes the spring strip to deform outwards, disengaging the latching block from the latching groove, thus facilitating the unlocking of the socket or plug.

[0012] In summary, the technical effects and advantages of this utility model are as follows: 1. In the non-connected state, use the movable stop to block the outside of the connecting pole to prevent contact with the human body. Insert the plug into the socket and use the plug to squeeze the connecting pole, so that the movable stop overcomes the spring force and retracts inward, allowing the connecting pole to be inserted into the plug and connect with the plug. During the plugging process, the conductor is always shielded inside, improving the safety of the connection process.

[0013] 2. Utilize the elasticity of the spring bar to keep the buckle in the slot. Press the button to activate the spring bar, causing it to deform and disengage the buckle from the slot, making it easy to unlock the socket or plug. Attached Figure Description

[0016] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments.

[0017] like Figure 1As shown, a high-voltage power harness with an anti-interference shielding structure includes a socket 2. A connecting rod 3 is fixedly connected inside the socket 2. A movable stop 4 is movably fitted outside the connecting rod 3, slidingly installed inside the socket 2. A spring-loaded latch 6 is fixedly connected outside the socket 2. A plug 5 is inserted into the socket 2. The connecting rod 3 and plug 5 are plugged in and electrically connected. The spring-loaded latch 6 is engaged with the plug 5. A spring 1 is movably fitted outside the connecting rod 3. One end of the spring 1 is fixedly connected to the socket 2, and the other end is fixedly connected to the movable stop 4. In the non-connected state, the movable stop 4 blocks the connecting rod 3 to prevent contact with the human body. When the plug 5 is inserted into the socket 2, the plug 5 presses against the connecting rod 3, causing the movable stop 4 to retract against the spring force of the spring 1, allowing the connecting rod 3 to insert into the plug 5 and mate with it. During the insertion process, the conductor remains shielded internally.

[0018] like Figure 1 and 2 As shown, the socket 2 includes a base 21, on which a first high-voltage wire harness body 22 is fixedly connected. The movable stop 4 is guided to slide by the inner wall of the base 21.

[0019] like Figure 1 , 2 As shown in Figure 3, the power receiving pole 3 includes a pole body 31, with a conductive plate 32 fixedly connected inside the pole body 31. The root of the pole body 31 is fixedly connected to the inside of the base body 21, and the conductive plate 32 is electrically connected to the first high-voltage wire harness body 22. The power receiving pole 3 is electrically connected to the plug 5 through the conductive plate 32.

[0020] like Figure 1 , 3 As shown in Figure 4, the movable stop 4 includes a block 41 with a sliding hole 42 hollowed out inside. The rod 31 is slidably inserted into the sliding hole 42. In the non-connected state, the block 41 covers the rod 31. When connected, the plug 5 and the block 41 are used to shield the conductive sheet 32.

[0021] like Figure 1 , 3 As shown in Figure 5, the plug 5 includes a housing 51. A snap-fit ​​groove 54 is provided on the side of the housing 51. An elastic conductive sheet 53 is fixedly connected inside the housing 51. A second high-voltage wire harness body 52 is fixedly connected to the housing 51. The elastic conductive sheet 53 is electrically connected to the second high-voltage wire harness body 52, and the conductive sheet 32 ​​is mated with the elastic conductive sheet 53. After the connecting rod 3 is inserted into the housing 51, the conductive sheet 32 ​​contacts the elastic conductive sheet 53, thus electrically connecting the connecting rod 3 to the plug 5.

[0022] like Figure 1 , 2As shown in Figures 5 and 6, the spring clip 6 includes a spring strip 61. The tail of the spring strip 61 is fixedly connected to the base 21. A button 63 is fixedly connected to the outside of the spring strip 61, and a fastening block 62 is fixedly connected to the head of the spring strip 61. The fastening block 62 engages and matches with the fastening groove 54. The elastic force of the spring strip 61 acts on the fastening block 62, keeping the fastening block 62 fastened in the fastening groove 54. Pressing the button 63 causes the spring strip 61 to deform outward, thus disengaging the fastening block 62 from the fastening groove 54.

[0023] Working principle: In the non-connected state, the movable stop 4 is used to block the outside of the connecting rod 3 to prevent contact with the human body. The plug 5 is inserted into the socket 2. The plug 5 squeezes the connecting rod 3, causing the movable stop 4 to overcome the elastic force of the spring 1 and retract, so that the connecting rod 3 is inserted into the plug 5 and connects with the plug 5. During the connection process, the conductor is always shielded inside.
