Abstract
Description
Technical Field
[0001] This utility model relates to the field of passenger vehicle technology, specifically to a bundled device for concealed door wiring harnesses in new energy passenger vehicles. Background Technology
[0002] The primary function of the door wiring harness is to connect the electrical equipment on the door to the vehicle's main electrical system, ensuring that these devices function properly. Due to the increasing number of electrical components and functional requirements on car doors, the design of door wiring harnesses has become increasingly complex, making them a frequent source of malfunctions in modern vehicles. Generally, a fixing point needs to be added 120mm from the wiring harness connector to minimize the burden on the terminals within the connector due to wiring harness vibration and weight.
[0003] Currently, during the installation of door wiring harnesses, workers typically bundle two harnesses together with tape and then hide them under the car's floor mat. When the harnesses are powered on for extended periods, they can overheat. Direct contact between the two harnesses could lead to a fire and short circuit, posing a safety hazard. Furthermore, when installing the harnesses and connectors, the connection points are usually housed in a small junction box for protection. However, opening and closing the junction box typically requires a small, specialized screwdriver, and the assembly screws are also quite small. During installation or disassembly, screws may be lost, or the junction box may be impossible to open without a specialized screwdriver, making the installation and maintenance of the wiring inside the junction box quite troublesome. Utility Model Content

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0021] Please see Figure 1-4As shown, a bundled device for a concealed door wiring harness in a new energy passenger vehicle includes a junction box 1. The junction box 1 facilitates the connection between the wiring harness body 3 and the plug 2, allowing the plug 2 to be inserted into the vehicle. The junction box 1 includes a box body 11, with a cover 12 on one side. A protective cover 13 is fixed to one side of the cover 12. Both the protective cover 13 and the cover 12 have wire-passing holes 14 on their inner walls. Two symmetrical positioning plates 15 are fixed to the inner wall of the box body 11. The inner wall of the positioning plates 15 has a locking hole 16, and a locking pin 17 is inserted into the inner wall of the locking hole 16, fixing the locking pin 17 to one side of the cover 12. The inner wall of the locking pin 17 has two symmetrical limiting holes 18, and the inner wall of the positioning plates 15 has two symmetrical moving grooves 19. The moving grooves 19... A spring 110 is fixed to the inner wall, and a limit pin 111 is fixed to one end of the spring 110. The limit pin 111 is engaged with the inner wall of the limit hole 18. The box body 11 facilitates the connection of the wire harness body 3 and the plug 2 inside the box via the terminal block. The box cover 12 seals the box body 11 to prevent damage to the wiring points inside the box and to prevent accidental electric shock. Both the box body 11 and the box cover 12 are made of insulating material. The protective cover 13 protects the wire harness body 3 when it enters the box cover 12, extending the service life of the wire harness body 3. The wire harness body 3 can easily enter the box body 11 through the wire hole 14 on the inner wall of the protective cover 13 and the box cover 12. Two symmetrical positioning plates are fixed to the inner wall of the box body 11. Positioning plate 15 facilitates the assembly and disassembly of the lid 12 and the body 11. A locking hole 16 on the inner wall of positioning plate 15 allows the locking pin 17 on the lid 12 to be inserted, connecting the lid 12 and the body 11. When the locking pin 17 is inserted into the locking hole 16, it presses against the spherical limiting pin 111, causing the limiting pin 111 to compress the spring 110. The spring 110 extends and retracts within the moving groove 19. As the locking pin 17 continues to move into the locking hole 16 until the limiting pin 111 aligns with the limiting hole 18, the limiting pin 111 returns to its original position under the elastic force of the spring 110, locking into the limiting hole 18. This fixes the locking pin 17 to the positioning plate 15, thereby fixing the lid 12 to the body 11. When disassembling the lid 12, the user can pinch the lid 12 with their fingers. 2. Pull outwards from both sides, the latch 17 on the cover 12 is affected by the pulling force, and the spherical limiting pin 111 is squeezed out of the limiting hole 18. After the limiting pin 111 is separated from the limiting hole 18, the latch 17 is pulled out from the latch hole 16 in the positioning plate 15. Two symmetrical plugs 2 are fixed on one side of the junction box 1, and two wire harness bodies 3 corresponding to the plugs 2 are also electrically connected inside the junction box 1. One end of the wire harness body 3 is detachably installed with a motor terminal 4. By setting the plugs 2, they can be inserted into the door electronic components inside the vehicle to make the door powered and facilitate the control of automatic equipment such as windows and door locks. By setting the wire harness body 3, it is used for power transmission. By setting the motor terminal 4, it is easy to connect the wire harness body 3 to the vehicle motor to make the wire harness body 3 powered.
[0022] A protective component 5 is installed on the outside of the wire harness body 3 to extend its service life. This component protects the wire harness body 3 from direct contact with the outside environment, thus extending its lifespan. The protective component 5 includes an insulating frame 51 installed on the outside of the wire harness body 3. A partition frame 52 is fixed to the inner wall of the insulating frame 51, a filling layer 53 is provided on the outside of the partition frame 52, and several reinforcing ribs 54 are fixed to the outside of the insulating frame 51. An outer sheath layer 55 is fixed to the outside of the reinforcing ribs 54. The insulating frame 51 facilitates the connection of two wire harness bodies 3. The two wire harness bodies 3 are separated by a partition 52 to prevent direct contact between them and thus avoid short circuits. A polyethylene filling layer 53 is added between the wire harness body 3 and the insulating frame 51 to prevent the wire harness body 3 from shaking inside the insulating frame 51. Several reinforcing ribs 54 are fixed on the outside of the insulating frame 51 to improve the compressive strength of the insulating frame 51 and extend its service life, which in turn extends the service life of the wire harness body 3. An outer sheath 55 is provided to wrap the insulating frame 51 and the reinforcing ribs 54, improving the protection effect.
[0023] Working principle: The operator inserts the two wire harness bodies 3 from the protective component 5 into the box 11 through the wire holes 14 on the box cover 12 and the protective cover 13. The two wire harness bodies 3 are connected to the two corresponding pins 2 through the terminals in the box 11. After the connection is completed, the box cover 12 is closed, and the pins 2 are inserted into the electronic components of the car door inside the vehicle. The other end of the two wire harness bodies 3 is connected to the motor terminal 4. The motor terminal 4 is inserted into the vehicle motor to energize the wire harness bodies 3, thereby energizing the electronic components inside the car door.
