Description

Technical Field

[0001] The utility model relates to the technical field of automotive wire harnesses, and specifically relates to an automotive communication wire harness. Background Technique

[0002] In modern automotive electrical systems, the automotive wire harness, as a key carrier for signal transmission and power delivery between various electrical components of the vehicle, the performance of its connection terminals directly affects the reliability and safety of the entire vehicle's electrical system. The connection terminals achieve rapid connection between the wire harness and electrical equipment through a plug-in method. To ensure the stable operation of the vehicle in complex environments, the sealing and waterproof function between the connection terminals and the plug connectors is indispensable.

[0003] However, in the prior art, after the connection terminals of the automotive wire harness are plugged in, the sealing and waterproof effect between them and the plug connectors is generally poor. The unreasonable design of the plug-in structure causes gaps between the end faces of the connection terminals and the plug connectors, and it is extremely easy for rainwater, moisture, etc. to invade, thereby triggering faults such as oxidation and short circuit of the internal wires of the wire harness. The above problems will not only affect the normal use of the automotive wire harness, reduce the service life of the vehicle's electrical system, but may also pose a threat to driving safety in extreme cases. Content of the Utility Model

[0004] Based on this, the purpose of the present utility model is to provide an automotive communication wire harness to solve the technical problems in the above background technique.

[0005] To achieve the above purpose, the present utility model provides the following technical solution: An automotive communication wire harness includes an automotive wire harness and connection terminals connected to both ends thereof. The connection terminals are composed of a terminal head, a conductive head, and a terminal ring;

[0006] One side inside the terminal head is slidably connected with a sliding sealing ring extending to the outside thereof, and a sliding ring is fixed inside the sliding sealing ring. Dynamic sealing mechanisms are provided at the four corners on the outside of the terminal ring. The dynamic sealing mechanism includes a turning plate, a traction arm, and a traction rod. The turning plate and the terminal ring are elastically rotatably connected, and the traction arms are fixed at both ends of the turning plate, and the traction arms and the sliding ring are movably connected through the traction rod;

[0007] The dynamic sealing mechanism further includes a rotating shaft fixedly connected to the turning plate. Installation shells matching with the four groups of turning plates are fixed at the four corners on the outside of the terminal ring, and an activity hole matching with the rotating shaft is opened inside the installation shell;

[0008] The dynamic sealing mechanism further includes spring pieces. Spring pieces are fixed between the terminal ring and the four groups of turning plates, and clamping grooves matching with the spring pieces are provided on the outside of the terminal ring and the inside of the turning plate;

[0009] At the four corners inside the terminal ring, cavities are provided for cooperating with four groups of dynamic sealing mechanisms, and the sliding ring is located on one side inside the cavity and is slidably connected thereto.

[0010] By adopting the above technical solution, in terms of sealing protection, when the connecting terminal is inserted into the socket, the turning plate is squeezed to drive the sliding sealing ring to axially move and press against the end face of the socket, forming a dynamic sealing interface. Combining with the elastic restoring force of the spring piece, it can closely fit the inner hole wall of the socket, prevent rainwater and moisture from invading, greatly reduce the risk of oxidation and short circuit of the wires inside the wire harness, and ensure the stable operation of the automotive electrical system in a complex environment.

[0011] Further, the dynamic sealing mechanism further includes a movable sleeve and a hinge seat. The traction rod and the traction arm are movably connected through the movable sleeve, and the traction rod and the sliding ring are rotatably connected through the hinge seat.

[0012] By adopting the above technical solution, both ends of the traction rod are movably connected, thus avoiding the problem of interference between the traction rod and the sliding ring when the traction arm pulls the traction rod.

[0013] Further, the...

[0014] In summary, the present utility model mainly has the following beneficial effects:

[0015] 1. In terms of sealing protection, when the connecting terminal is inserted into the socket, the turning plate is squeezed to drive the sliding sealing ring to axially move and press against the end face of the socket, forming a dynamic sealing interface. Combining with the elastic restoring force of the spring piece, it can closely fit the inner hole wall of the socket, prevent rainwater and moisture from invading, greatly reduce the risk of oxidation and short circuit of the wires inside the wire harness, and ensure the stable operation of the automotive electrical system in a complex environment;

[0016] 2. In terms of structural design and adaptability, four groups of dynamic sealing mechanisms are evenly distributed on the outer side of the terminal ring. Through the linkage of components such as the rotating shaft, the traction arm, and the traction rod, it can adapt to the inner holes of sockets with different sizes, ensuring the consistency of the sealing effect. The elastic compensation design of the spring piece can effectively cope with the wear caused by long-term plugging and unplugging, extend the service life of the wire harness. In addition, the entire sealing process does not require additional tools and can be completed by manual plugging, which not only meets the rapid assembly requirements of automotive wire harnesses but also improves production efficiency, providing strong support for the safety and reliability of the automotive electrical system.

Specific embodiments

[0025] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below by referring to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0026] Next, the embodiments of the present utility model will be described according to its overall structure. Embodiment

[0027] As Figure 1-7 shown, this embodiment focuses on the automotive communication wiring harness, and its structural design focuses on dynamic sealing and stable connection. It mainly consists of an automotive wiring harness 1 and a connection terminal 2. The connection terminal 2 includes a terminal head 201, a conductive head 202, a terminal ring 203, and a dynamic sealing mechanism 3;

[0028] The connection terminal 2, as the core component, integrates the functions of conduction and sealing, including a terminal head 201, a conductive head 202, a terminal ring 203, and a dynamic sealing mechanism 3. The terminal head 201 is an insulating shell, and a sliding sealing ring 4 is slidably connected inside it. The inner side is linked with the dynamic sealing mechanism 3 through a sliding ring 5;

[0029] The conductive head 202 is embedded in the terminal head 201 and is a metal conductor for electrical signal connection. The terminal ring 203 surrounds the outside of the conductive head 202, and a dynamic sealing mechanism 3 is provided at the four corners. A cavity 7 is opened inside for the axial movement of the sliding ring 5;

[0030] The dynamic sealing mechanism 3 includes a flip plate 301, a rotating shaft 302, a traction arm 303, a traction rod 304 and a spring piece 305. Four groups of flip plates 301 are rotatably connected to the mounting shell 6 outside the terminal ring 203 through the rotating shaft 302. The rotating shaft 302 is embedded in the movable hole of the mounting shell 6. The traction arms 303 are fixed at both ends of the flip plate 301 and are movably connected to the traction rod 304 through movable sleeves 306. The other end of the traction rod 304 is rotatably connected to the sliding ring 5 through a hinge seat 307. The spring piece 305 is installed between the terminal ring 203 and the flip plate 301, and both ends are snapped into the corresponding card slots to provide an elastic reset force;

[0031] The above parts achieve dynamic sealing during the plugging process through mechanical linkage. When inserting the plug connector, the flip plate 301 is squeezed and flipped, and the sliding ring 5 is pulled through the traction arm 303 and the traction rod 304 to drive the sliding sealing ring 4 to axially move, and finally press against the end face of the plug connector. The spring piece 305 provides continuous elastic force after the plugging is in place to ensure sealing reliability and connection stability;

[0032] Terminal plugging process

[0033] Align the connection terminal 2 with the inner hole of the automotive plug connector, and manually push the terminal head 201 to insert the terminal ring 203 and the conductive head 202 into the plug connector. During the insertion process, the inner hole wall of the plug connector squeezes the outside of the flip plate 301, causing it to flip around the rotating shaft 302 towards the terminal ring 203, and the spring piece 305 is compressed and deformed to store elastic potential energy;

[0034] Dynamic sealing trigger

[0035] When the flip plate 301 flips, the sliding ring 5 is pulled through the traction arm 303 and the traction rod 304 to axially slide along the cavity 7 of the terminal ring 203, driving the sliding sealing ring 4 to move towards the end face of the plug connector;

[0036] When the terminal ring 203 is completely inserted into the plug connector, the inclined edge of the sliding sealing ring 4 cuts into the inner hole edge of the plug connector, and after being compressed and deformed, it closely fits against the end face of the plug connector to form a sealing interface, preventing moisture and humidity from invading;

[0037] Stable connection and sealing maintenance

[0038] After the plugging is in place, the elastic reset force of the spring piece 305 pushes the outer surface of the flip plate 301 to press against the inner hole wall of the plug connector, fixes the position of the terminal through friction, and at the same time enhances the sealing reliability. The conductive head 202 is in full contact with the internal conductive components of the plug connector to achieve stable transmission of electrical signals or power;

[0039] Terminal disassembly and reset

[0040] When disconnecting the connection terminal 2, pull the terminal head 201 outwards. The flipping plate 301 is disengaged from the extrusion of the inner wall of the socket, and automatically resets under the action of the spring piece 305, driving the sliding sealing ring 4 to return to the initial position and restoring the relaxed state, facilitating the next insertion.

[0041] The working principle of the present utility model is as follows: This automotive communication wire harness consists of a group of automotive wire harnesses and the connection terminals 2 connected to both ends thereof. The conductive head 202 and the terminal ring 203 of the connection terminal 2 are inserted into the inner hole of the socket on the vehicle, and the communication transmission function is realized under the electrical connection action of the conductive head 202.

[0042] When the staff manually inserts the connection terminal 2 into the socket, as the connection terminal 2 extends, the inner wall of the socket will then extrude the flipping plates 301 of the four groups of dynamic sealing mechanisms 3, causing them to rotate passively along the rotating shafts 302. At this time, the spring pieces 305 are in a passively compressed state.

[0043] When the flipping plate 301 flips, the flipping plate 301 will drive the traction arm 303 to flip through the rotating shaft 302. When the traction arm 303 flips, it will then pull the sliding ring 5 to axially slide through the traction rod 304. The axially sliding sliding ring 5 will synchronously drive the sliding sealing ring 4 to axially move. At this time, the sliding sealing ring 4 moves towards the position closer to the socket.

[0044] When the terminal ring 203 is about to be completely inserted into the inner hole of the socket, at this time, the sliding sealing ring 4 just axially moves to the end face position of the socket. Since one side edge of the sliding sealing ring 4 is inclined, after the terminal ring 203 is completely inserted into the socket, the inclined surface of one side of the sliding sealing ring 4 will be inserted into the edge of the inner hole of the socket. At the same time, the sliding sealing ring 4 is passively compressed and deformed, thereby ensuring the end face sealing connection between the connection terminal 2 and the automotive socket, and further avoiding the problem that external moisture or water vapor enters the conductive head 202 and causes it to oxidize.

[0045] Furthermore, when the insertion is complete, the flipping plate 301 will, under the reaction force of the spring piece 305, press the outer surface of the flipping plate 301 tightly against the inner wall of the socket, thereby ensuring the stability of the overall insertion and further ensuring the normal use of the automotive communication wire harness.

The specific features, structures, materials, or characteristics described can be combined in a suitable manner in any one or more embodiments or examples.
