Description

Technical Field

[0001] This utility model belongs to the field of automotive wiring harness technology, and specifically relates to an automotive wiring harness that is easy to connect. Background Technology

[0002] Automotive wiring harnesses are the main network of automotive circuits. They are responsible for connecting various electrical devices in the vehicle and ensuring the stability of electrical signal transmission and power supply.

[0003] Currently, Chinese utility model patent CN215896839U discloses an automotive wiring harness that facilitates connection. Traditional automotive wiring harness connection methods often rely on simple plug-in structures, such as using a spring plate on the connector to achieve contact and fixation with the terminal through its rebound force. While this method may meet usage requirements in static environments, during vehicle operation, factors such as engine vibration and road bumps can easily cause continuous micro-movements between the wiring harness connector and the plug-in terminal, directly impacting the spring plate. This leads to spring plate fatigue, reduced contact force, and ultimately, poor contact. Furthermore, this structure often requires pressing the spring plate and pulling out the connector simultaneously during disassembly, which is inconvenient, especially in confined spaces or densely packed wiring environments like automobiles, further increasing maintenance difficulty. Utility Model Content

[0004] The purpose of this utility model is to provide an easy-to-connect automotive wiring harness. Its advantage is that the connection between the automotive wiring harness connector and the terminal is changed from a spring plate to an arc-shaped spring plate, thereby preventing the plug-in terminal from directly contacting the arc-shaped spring plate and avoiding vibration from affecting the clamping force of the arc-shaped spring plate.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: an automotive wiring harness that is easy to connect, comprising an automotive wiring harness body, a wiring harness connector fixedly connected to one end of the automotive wiring harness body, a connector terminal slidably inserted into the end of the wiring harness connector away from the automotive wiring harness body, a sliding groove provided on both sides of the surface of the wiring harness connector, a bending spring plate installed inside the sliding groove, a snap-fit ​​groove provided on both sides of the inside of the connector terminal for engaging with the bending spring plate, a sliding cap slidably connected to both sides of the surface of the connector terminal, a spring plate top rod welded inside the sliding cap and slidably connected through the snap-fit ​​groove, and a return spring fixedly connected to the connector terminal and the sliding cap respectively on the surface of the spring plate top rod.

[0006] The above technical solution involves inserting the wire harness connector into the plug terminal. After being compressed, the bending spring plate moves into the locking groove and springs back to its original position, causing it to protrude again within the groove. This automatically locks the wire harness connector in place after insertion, preventing it from dislodging due to vibrations during vehicle operation and improving connection stability. When the wire harness connector is inserted into the plug terminal, the connector push plate is pressed into the terminal. After manually pressing the sliding cap to flatten the bending spring plate, the spring force of the push plate pushes the wire harness connector out of the plug terminal. This avoids the inconvenience of simultaneously pressing the sliding cap and pulling out the wire harness connector, improving practicality.

[0007] The present invention is further configured such that a connector push plate is slidably connected to the top and bottom of the plug-in terminal near the wire harness connector, and a push plate spring that is locked inside the plug-in terminal is fixedly connected to the side of the connector push plate away from the wire harness connector.

[0008] The above technical solution is adopted to prevent the inconvenience of having to pull out the wire harness connector at the same time when pressing the sliding cap, thus improving practicality.

[0009] The present invention is further configured such that the end of the bending spring plate near the plug-in terminal is fixedly connected to the inside of the slide groove, and the end of the bending spring plate away from the plug-in terminal is slidably connected to the inside of the slide groove.

[0010] The above technical solution allows the slidable end of the curved spring plate to slide inside the groove after being compressed, thereby flattening the curved spring plate and allowing the wire harness connector to be inserted into the plug terminal.

[0011] The present invention is further configured such that a connector conductor electrically connected to the main body of the automotive wiring harness is fixedly connected inside the wiring harness connector, and a terminal conductor slidably inserted into the connector conductor is fixedly connected inside the plug terminal.

[0012] The above technical solution involves interconnecting wire harness connectors and plug-in terminals, allowing the terminal conductors to conduct electricity with the automotive wire harness body through the connector conductors.

[0013] The present invention is further provided that anti-slip stripes are provided on the sides of the wire harness connector and the plug terminal that are far apart from each other.

[0014] The above technical solution increases surface friction, making it easier to plug and unplug wire harness connectors and terminals.

[0015] The present invention is further configured such that a sealing strip is fixedly sleeved on the side of the plug-in terminal near the wire harness connector.

[0016] The above technical solution improves the sealing performance of wire harness connectors and plug terminals after insertion, preventing moisture from seeping into the interior.

[0017] The present invention is further configured such that the wire harness connector and the plug terminal are both made of rubber, and the connector conductor and the terminal conductor are both made of copper alloy and have a tin plating layer on their surface.

[0018] The above technical solution is adopted to prevent copper alloys from easily oxidizing in air and to ensure the conductivity of the connector conductors and terminal conductors after they are plugged in.

[0019] In summary, this utility model has the following beneficial effects: 1. By inserting the wire harness connector into the plug terminal, the bending spring plate moves into the locking groove after being squeezed and then springs back to its original position, causing the bending spring plate to protrude again inside the locking groove. This automatically locks the wire harness connector in place after it is inserted into the plug terminal, preventing it from dislodging due to vibrations during vehicle operation and improving connection stability. 2. When inserting the wire harness connector into the plug terminal, the connector push plate is pressed into the plug terminal. After manually pressing the sliding cap to flatten the bent spring plate, the push plate spring force pushes the wire harness connector out of the plug terminal. This prevents the inconvenience of having to simultaneously pull out the wire harness connector while pressing the sliding cap, thus improving practicality. Attached Figure Description

[0022] The present invention will be further described in detail below with reference to the accompanying drawings.

[0023] Example 1: refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 An easy-to-connect automotive wiring harness includes an automotive wiring harness body 1. A wiring harness connector 2 is fixedly connected to one end of the automotive wiring harness body 1. A connector terminal 3 is slidably inserted into the end of the wiring harness connector 2 away from the automotive wiring harness body 1. Sliding grooves 4 are formed on both sides of the surface of the wiring harness connector 2. A bending spring plate 5 is installed inside the sliding groove 4. Snap-fit ​​grooves 6 are formed on both sides of the interior of the connector terminal 3, engaging with the bending spring plate 5. Sliding caps 7 are slidably connected to both sides of the surface of the connector terminal 3. A spring plate top rod 8, which is slidably connected through the snap-fit ​​groove 6, is welded inside the sliding cap 7. A return spring 9, fixedly connected to both the connector terminal 3 and the sliding cap 7, is sleeved on the surface of the spring plate top rod 8. When the wiring harness connector 2 is inserted into the connector terminal 3, the bending spring plate 5, after being compressed, moves into the snap-fit ​​groove 6 and springs back to its original position, causing the bending spring plate 5 to protrude again inside the snap-fit ​​groove 6. This automatically locks the wiring harness connector 2 into place after it is inserted into the connector terminal 3, preventing disengagement due to vibration during vehicle operation and improving connection stability. When the wire harness connector 2 is inserted into the plug terminal 3, the connector push plate 10 is pressed into the plug terminal 3. After manually pressing the sliding cap 7 to flatten the bent spring plate 5, the return force of the push plate spring 11 pushes the wire harness connector 2 out of the plug terminal 3. This prevents the inconvenience of having to pull out the wire harness connector 2 while pressing the sliding cap 7, thus improving practicality.

[0024] refer to Figure 3 , Figure 4 The top and bottom of the plug-in terminal 3 near the wire harness connector 2 are slidably connected to a connector push plate 10. The side of the connector push plate 10 away from the wire harness connector 2 is fixedly connected to a push plate spring 11 that is engaged with the inside of the plug-in terminal 3. This prevents the inconvenience of having to pull out the wire harness connector 2 while pressing the sliding cap 7, thus improving practicality.

[0025] refer to Figure 2 One end of the bending spring plate 5 near the plug terminal 3 is fixedly connected to the inside of the slide groove 4, and the other end of the bending spring plate 5 away from the plug terminal 3 is slidably connected to the inside of the slide groove 4. When the slidable end of the bending spring plate 5 is compressed, it slides inside the slide groove 4, thereby flattening the bending spring plate 5 so that the wire harness connector 2 can be inserted into the plug terminal 3.

[0026] refer to Figure 2 , Figure 3 The wiring harness connector 2 has a connector conductor 12 that is electrically connected to the main body 1 of the vehicle wiring harness, and the plug terminal 3 has a terminal conductor 13 that is slidably inserted into the connector conductor 12. The wiring harness connector 2 and the plug terminal 3 are plugged into each other, so that the terminal conductor 13 conducts electricity with the main body 1 of the vehicle wiring harness through the connector conductor 12.

[0027] refer to Figure 1 Anti-slip stripes 14 are provided on the opposite sides of the surfaces of the wire harness connector 2 and the plug terminal 3. This increases surface friction and facilitates insertion and removal between the wire harness connector 2 and the plug terminal 3.

[0028] refer to Figure 1 , Figure 3 A sealing strip 15 is fixedly fitted onto the side of the plug terminal 3 near the wire harness connector 2. This improves the sealing performance of the wire harness connector 2 and plug terminal 3 after they are plugged in, preventing moisture from seeping into the interior.

[0029] refer to Figure 2 , Figure 3 , Figure 4 Both the wire harness connector 2 and the plug-in terminal 3 are made of rubber, while the connector conductor 12 and the terminal conductor 13 are made of copper alloy with a tin plating layer on the surface. This prevents the copper alloy from easily oxidizing in the air and ensures the conductivity of the connector conductor 12 and the terminal conductor 13 after plugging in.

[0030] Brief description of usage: By sliding the wire harness connector 2 into the plug terminal 3, the arc-shaped protrusion of the bending spring plate 5 inside the plug terminal 3 overcomes the elastic force during insertion, causing the slidable end of the bending spring plate 5 to slide inside the slide groove 4 after being subjected to force, thereby flattening the bending spring plate 5 inside the slide groove 4. When the wire harness connector 2 is fully inserted into the plug terminal 3, the arc-shaped protrusion of the bending spring plate 5 slides into the locking groove 6 inside the plug terminal 3, allowing the bending spring plate 5 to spring back and protrude again, locking the wire harness connector 2 inside the plug terminal 3 and preventing it from detaching. At the same time, when it is necessary to remove the wire harness connector 2, the sliding cap 7 is pressed to overcome the elastic force of the return spring 9, causing the sliding cap 7 to push the spring plate top rod 8 into the locking groove 6, thereby manually pressing the bending spring plate 5 again to flatten it. At this time, the wire harness connector 2 can be pulled out from the plug terminal 3. The sliding cap 7 then drives the spring plate top rod 8 to return to its original position through the return force of the return spring 9.

[0031] Simultaneously, when the wire harness connector 2 is inserted into the plug terminal 3, the connector push plate 10 can be squeezed to overcome the elastic force of the push plate spring 11, causing the connector push plate 10 to slide into the plug terminal 3. When the sliding cap 7 is manually pressed to flatten the bent spring plate 5, the wire harness connector 2 can be pushed outward by the rebound force of the push plate spring 11, thereby automatically pushing the wire harness connector 2 out of the plug terminal 3, preventing the inconvenience of having to pull out the wire harness connector 2 at the same time when pressing the sliding cap 7.

[0032] It should be noted that parts have a lifespan and can be replaced during regular maintenance when they no longer meet performance requirements. Deterioration in performance due to prolonged use of parts is not a design defect of this application.

[0033] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
