Description

Technical Field

[0001] This utility model relates to the field of wire harness technology, specifically a modular wire harness structure. Background Technology

[0002] In the field of engineering vehicles, wiring harnesses are key components for power transmission and signal transmission. Their design and performance are crucial to ensuring the normal operation of vehicles. Traditional wiring harness structures typically include basic components such as wires and connectors (e.g., male and female connectors).

[0003] Traditional connectors and wires are typically fixed using riveting or welding. Once connected, subsequent maintenance and replacement become extremely difficult, and inconsistent welding quality can lead to poor contact. This is especially problematic in applications like engineering vehicles that frequently face harsh environments, where traditional wiring harness structures prove inadequate. External factors such as dust and moisture can easily penetrate the connector, posing a risk of short circuits or open circuits. If a wire in the wiring harness fails, the entire harness needs to be replaced, increasing operating costs and requiring the maintenance of multiple spare wires of various models and specifications. This undoubtedly increases the complexity and cost of inventory management. Therefore, a modular wiring harness structure is needed to solve these problems. Summary of the Invention

[0004] The purpose of this utility model is to provide a modular wire harness structure that has the advantages of quick installation and disassembly, high connection stability and environmental adaptability, and solves the problems of difficult maintenance and high cost of traditional wire harnesses.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a modular wire harness structure, including a male connector, a wire, and a female connector, wherein the side end faces of the male connector and the female connector are provided with a wire pressing mechanism;

[0006] The conductor includes a conductive wire, an insulating sheath, and terminals. The male connector has a copper sleeve clamp that mates with the terminal, and the female connector has a copper post clamp that mates with the terminal. The male and female connectors conduct electricity through the copper sleeve clamp and the copper post clamp. The bottom of the male and female connectors has evenly spaced wire holes, and the sides of the male and female connectors have concealed grooves. The grooves have through holes that communicate with the wire holes. The wire clamping mechanism includes a clamping rod and a protective cover. The clamping rod is movably installed in the through hole, and the protective cover is installed in the concealed groove.

[0007] Preferably, the ends of the copper column clamp and the copper sleeve clamp are provided with conductive plates and elastic hooks, the side of the terminal is provided with a second slot that cooperates with the elastic hook, and the top edge of the terminal is chamfered.

[0008] Preferably, the side end face of the through hole of the pressure rod is provided with a second rotating shaft that is rotatably connected to the center of the pressure rod, the outer end face of the buckle of the elastic hook is provided with a vertical plate, the side end face of the vertical plate is provided with a sliding rod, and the end of the pressure rod is provided with a sliding groove that slides with the sliding rod.

[0009] Preferably, a torsion spring is fitted on the second rotating shaft, and the pressure rod and the female connector are elastically rotatably connected through the torsion spring.

[0010] Preferably, the side wall of the dark groove is provided with a first rotating shaft, and the protective cover is installed on the rotating shaft and rotatably connected to the female connector.

[0011] Preferably, the protective cover has a retaining strip on both the left and right sides, and the side end face of the hidden groove has a first retaining groove that cooperates with the retaining strip.

[0012] Preferably, the edge of the protective cover is provided with an arc-shaped flange.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The quick-release design of the wires, male connectors, and female connectors significantly improves the assembly efficiency, disassembly convenience, and safety of the wire harness. First, the copper sleeve clamps and copper post clamps inside the male and female connectors, together with the elastic hooks and slot structures of the terminals, achieve an insertion-type fixing method. This design not only simplifies the assembly process, but also ensures tight contact between the terminals and the conductive plates through the cooperation of the elastic hooks and slots, avoiding open circuits or overheating problems caused by poor contact, thereby improving the conductivity stability and safety of the wire harness.

[0015] 2. The design of the wire clamping mechanism further enhances the ease of wire harness disassembly. The clamping rod, through the sliding cooperation of the sliding rod and the elastic hook, allows the elastic hook to release the constraint of the terminal block simply by pressing the clamping rod when disassembly is required, thus easily removing the wire. This design not only simplifies the disassembly process but also avoids wire harness damage that may be caused by traditional disassembly methods, improving the maintenance efficiency of the wire harness and increasing the degree of assembly freedom. Users can freely choose the number of wires to install according to their own needs, and when a wire breaks, only the single wire needs to be replaced, without replacing the entire wire harness.

[0023] Please see Figures 1-6 A modular wire harness structure includes a male connector 1, a wire 2 and a female connector 3, and a wire pressing mechanism 4 is provided on the side end face of both the male connector 1 and the female connector 3.

[0024] The conductor 2 includes a conductive wire 201, an insulating sheath 202, and a terminal block 203. The male connector 1 is provided with a copper sleeve clamp 104 that mates with the terminal block 203, and the female connector 3 is provided with a copper post clamp 301 that mates with the terminal block 203. The male connector 1 and the female connector 3 conduct electricity through the copper sleeve clamp 104 and the copper post clamp 301. The way the copper post clamp 301 mates with the terminal block 203 is exactly the same as the way the copper sleeve connector mates with the terminal block 203. The bottom of the male connector 1 and the female connector 3 are evenly provided with wire holes 103, and the sides of the male connector 1 and the female connector 3 are provided with grooves 101. The groove 4013 is provided with a through hole 102 that communicates with the wire holes 103. The wire pressing mechanism 4 includes a pressing rod 401 and a protective cover 402. The pressing rod 401 is movably installed in the through hole 102, and the protective cover 402 is installed in the groove 101.

[0025] Furthermore, the ends of the copper column clamp 301 and the copper sleeve clamp 104 are provided with conductive plates 1041 and elastic hooks 1042, the side of the terminal 203 is provided with a second slot 2031 that cooperates with the elastic hook 1042, and the top edge of the terminal 203 is chamfered.

[0026] When the terminal 203 of the wire 2 is inserted into the wiring hole, the terminal 203 will push the elastic hook 1042 outward. If the terminal 203 is continued to be inserted, the elastic hook 1042 will pass over the side of the terminal 203 and insert into the second slot 2031, fixing the terminal 203 to the male connector 1 or female connector 3. The insertion fixing method greatly improves the assembly speed of the wire harness.

[0027] Furthermore, a second rotating shaft 4011 is provided on the side end face of the through hole 102 of the pressure rod 401 and is rotatably connected to the center of the pressure rod 401. A vertical plate 1043 is provided on the outer end face of the buckle of the elastic hook 1042. A sliding rod 1044 is provided on the side end face of the vertical plate 1043. A sliding groove 4013 is provided at the end of the pressure rod 401 and is slidably engaged with the sliding rod 1044.

[0028] By pressing the end of the pressure rod 401 away from the slide groove 4013, the pressure rod 401, under the action of leverage, pulls the elastic hook 1042 outward through the slide rod 1044, thereby releasing the elastic hook 1042 from the constraint of the terminal 203, so that the terminal 203 can be taken out from the wire hole 103, improving the convenience of wire harness disassembly.

[0029] Furthermore, a torsion spring 4012 is fitted on the second rotating shaft 4011, and the pressure rod 401 and the female connector 3 are elastically rotatably connected through the torsion spring 4012.

[0030] Under the action of the torsion spring 4012, the pressure rod 401 squeezes the end of the elastic hook 1042, thereby clamping the terminal 203 between the elastic hook 1042 and the conductive sheet 1041. This improves the firmness of the wire 2 and the fit between the terminal 203 and the conductive sheet 1041, preventing poor contact from causing a circuit break or excessive heat generation that could lead to an accident.

[0031] Furthermore, the side wall of the concealed channel 101 is provided with a first rotating shaft 4023, and the protective cover 402 is installed on the rotating shaft and rotatably connected to the female connector 3.

[0032] The flip-top protective cover 402 is used to open the pressure rod 401 when it is necessary to remove the wire 2. During daily use, the protective cover 402 covers the upper end of the pressure rod 401 to prevent accidental contact and wire detachment, prevent the pressure rod 401 from being bumped and deformed, and prevent dust from falling into the through hole 102, which would affect the conductivity.

[0033] Furthermore, the left and right sides of the protective cover 402 are provided with the retaining strip 4021, and the side end face of the hidden groove 101 is provided with the first retaining groove 1011 that cooperates with the retaining strip 4021.

[0034] The snap-fit ​​protective cover 402 structure prevents the protective cover 402 from opening automatically during daily use, and allows for quick and easy opening of the protective cover 402 to replace the wire 2 when maintenance is required.

[0035] Furthermore, the edge of the protective cover 402 is provided with an arc-shaped flange 4022.

[0036] The curved flange 4022 makes it easy for fingers to pry open the protective cover 402, preventing accidental contact with the pressure lever 401 and damage to it, thus further improving the ease of operation.

[0037] When using this wiring harness, firstly, insert the terminal 203 of wire 2 into the wire hole 103 of the male connector 1 or female connector 3. Due to the elastic hooks 1042 at the ends of the copper post clamp 301 and the copper sleeve clamp 104, when the terminal 203 is inserted, the terminal 203 will push the elastic hooks 1042 outward. Continue inserting, and the elastic hooks 1042 will pass over the side of the terminal 203 and insert into the slot on the side of the terminal 203, thereby connecting the terminal 203 to the male connector. The female connector 1 or 3 is fixed in place. This insertion-type fixing method greatly improves the assembly speed of the wire harness. After the terminal block 203 is fixed, the protective cover 402 is placed inside the recess 101. The retaining strips 4021 on the left and right sides of the protective cover 402 cooperate with the first retaining groove 1011 on the side end face of the recess 101 to prevent the protective cover 402 from opening automatically. In daily use, the protective cover 402 can prevent the wire end from falling off due to accidental contact with the pressure rod 401, and can also prevent the pressure rod 401 from being bumped and deformed, and from falling into the through hole 102. Dust affects conductivity. The arc-shaped flange 4022 on the edge of the protective cover 402 makes it easy to open the protective cover 402 with fingers and prevents accidental contact with the pressure lever 401, which may damage it. When it is necessary to disassemble the wire harness, open the protective cover 402 and press the end of the pressure lever 401 away from the slide groove 4013. Under the action of leverage, the pressure lever 401, through the sliding engagement with the slide rod 1044 on the outer end face plate 1043 of the elastic hook 1042, pulls the elastic hook 1042 outward, thus releasing the elastic hook 1042 from the lock. The terminal 203 is constrained, and at this time the terminal 203 can be taken out from the wire hole 103 to complete the wire harness disassembly. During use, the pressure rod 401 squeezes the end of the elastic hook 1042 under the action of the torsion spring 4012, so that the elastic hook 1042 and the conductive plate 1041 clamp the terminal 203, which not only improves the firmness of the wire 2 fixing, but also improves the fit between the terminal 203 and the conductive plate 1041, which can avoid poor contact causing open circuit or serious heat generation leading to accidents.

[0038] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
