Description

Technical Field

[0001] This utility model belongs to the field of automotive connector technology, specifically relating to a vehicle interface with a secure snap-fit ​​mechanism. Background Technology

[0002] When a button is controlled in the car, an electrical appliance (corresponding to the button's function) is activated; these are connected by wiring harnesses. High-end cars do not use many wiring harnesses, but instead use a CAN data bus to reduce the failure rate of the wiring harnesses; because there are too many wires, they are collectively referred to as the engine wiring harness.

[0003] Engine wiring harnesses typically consist of multiple strands of copper wire encased in plastic. Engine wiring harness connectors are a type of connector in the wiring harness system used to connect the harness to external devices or other wiring harnesses. After plugging the connector into another set of wires, it can be used. However, during use, the two connectors are fixed together without any limiting components. During prolonged vehicle operation, due to vehicle bumps and vibrations, the two connectors may shift, causing a signal break and preventing the buttons from functioning properly, thus affecting the normal operation of the vehicle. Utility Model Content

[0004] The purpose of this utility model is to provide a securely fastened vehicle interface to solve the problem mentioned in the background art, where, during the use of the wiring harness connector, the two connectors are plugged into each other and fixed, but there is no limiting component. During long-term vehicle operation, due to vehicle bumps, the two connectors may shift due to vibration, causing the signal between them to be disconnected, making it impossible to use the button normally and affecting the normal use of the car.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a vehicle interface with a secure snap-fit, comprising a connector one and a connector two movably connected to the connector one, wherein the outer walls on both sides of the connector one are integrally formed with limit posts, the outer walls of the connector two are movably connected to a limit frame, and the outer walls on both sides of the connector two are fixed with limit components, and the surface of the connector two is fitted with a limit buckle.

[0006] Both connector one and connector two are provided with a wiring port at one end, and a wire ring is fixed outside the wiring port of both connector one and connector two. An adjusting ring is movably connected to the outside of the wire ring. Two mounting holes are symmetrically opened inside the wire ring, and a fixing cylinder is fixed inside each of the two mounting holes of the wire ring.

[0007] In a further embodiment, both ends of the fixed cylinder are provided with movable grooves, and a push rod is movably connected in the movable groove of the fixed cylinder. A fixing block is fixed to the end face of the push rod located inside the guide ring.

[0008] In a further embodiment, a limiting ring is fixed to the outside of the push rod and movably connected to the fixed cylinder, and a support spring for supporting the limiting ring is sleeved on the outside of the push rod.

[0009] In a further embodiment, the inner walls on both sides of the adjusting ring are provided with inclined grooves for the push rod to move, and the part of the push rod that contacts the adjusting ring is a hemispherical structure.

[0010] In a further embodiment, the surface of the adjusting ring is provided with a threaded hole, and a fixing bolt is threaded into the threaded hole on the surface of the adjusting ring.

[0011] In a further embodiment, both outer walls of the limiting frame are provided with moving grooves for the limiting post to move, and both outer walls of the limiting frame are provided with limiting grooves that match the limiting member.

[0012] The technical effects and advantages of this utility model are as follows:

[0013] The securely fastened vehicle interface allows connector one and connector two to be interlocked. The limiting post is inserted into the moving slot of the limiting frame, which restricts the position of the limiting frame. The limiting frame fixes the position of connector two, preventing it from moving upwards. The limiting component is inserted into the limiting slot of the limiting frame, which further restricts the position of the limiting frame, preventing it from moving and ensuring the stability of the connection between connector one and connector two. It also prevents vibrations caused by vehicle movement from causing displacement between connector one and connector two, resulting in a signal disconnection and the inability to use the button normally, thus affecting the normal use of the car.

[0014] The wire is connected to connector one and connector two through the wire ring. By adjusting the ring, the push rod and the fixing block can be moved simultaneously, so that the two fixing blocks are simultaneously attached to both sides of the wire, which can fix the position of the wire. When external force is applied to the wire, it prevents the wire from separating from connector one and connector two, thereby ensuring the stability of data transmission.

[0015] The movable adjusting ring releases the restriction on the push rod. Under the elastic force of the support spring, the limiting ring and the push rod move, causing the fixing block to separate from the wire and releasing the restriction on the wire's position. This makes it easier to disassemble and assemble the wire during subsequent maintenance, making it more convenient to use. The securely fastened vehicle interface, through its double limiting structure, ensures a more stable connection between connector one and connector two, while also fixing the position of the wire to prevent it from separating from connector one or connector two under external force, thus avoiding a short circuit.

[0026] In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. However, it will be apparent to those skilled in the art that the present invention can be practiced without one or more of these details. In other instances, certain technical features well-known in the art have not been described in order to avoid confusion with the present invention.

[0027] Unless otherwise defined, the directions mentioned herein, such as up, down, left, right, front, back, inside, and outside, are based on the directions shown in the figures of this utility model, and are explained here together.

[0028] This utility model provides, for example Figure 1-8 The vehicle interface shown includes a connector 1 and a connector 2 movably connected to the connector 1. The outer walls of both sides of the connector 1 are integrally formed with limit posts 3. The outer walls of both sides of the connector 2 are provided with guide grooves for the movement of the limit posts 3. When the connector 1 and the connector 2 are inserted into each other, the movement of the connector 2 is not restricted. The connector 2 is externally connected to a limit frame 4, and the outer walls of both sides of the connector 2 are fixed with limit components 5. The outer walls of both sides of the limit frame 4 are provided with moving grooves for the movement of the limit posts 3, and the outer walls of both sides of the limit frame 4 are provided with limit grooves that match the limit components 5.

[0029] The outer walls of both sides of the limiting frame 4 have rotating holes for the limiting member 5 to rotate. Connector 1 and connector 2 are interlocked. The limiting post 3 is inserted into the moving groove of the limiting frame 4, and the limiting member 5 is inserted into the limiting groove of the limiting frame 4. Rotating the limiting frame 4 moves the limiting post 3 to the lowest point of the moving grooves on both sides of the limiting frame 4. At this point, the limiting member 5 and the limiting groove on the limiting frame 4 are misaligned, fixing the position of connector 2 and preventing connector 2 from moving upwards. The misalignment of the limiting member 5 and the limiting groove on the limiting frame 4 further controls the position of the limiting frame 4. To restrict movement of the limit frame 4 and ensure the stability of the connection between connector 1 and connector 2, and to prevent displacement between connector 1 and connector 2 caused by vibrations from vehicle movement, which would result in signal disconnection and inability to use the button normally, thus affecting the normal use of the car, a limit buckle 14 is installed on the surface of connector 2. A slot matching the limit buckle 14 is provided on one side of the limit frame 4. Pushing the limit buckle 14 moves it so that the limit buckle 14 is locked in the slot of the limit frame 4, thereby further fixing the position of the limit frame 4.

[0030] Both connector 1 and connector 2 have a wiring port at one end, and both connector 1 and connector 2 have an integrally formed wire ring 6 outside the wiring port. An adjusting ring 7 is movably connected to the outside of the wire ring 6. Two mounting holes are symmetrically opened inside the wire ring 6, and a fixing cylinder 8 is fixed in each of the two mounting holes of the wire ring 6 by screws. Both ends of the fixing cylinder 8 have a moving groove. A push rod 9 is movably connected in the moving groove of the fixing cylinder 8. The push rod 9 has a cuboid structure to prevent the push rod 9 from rotating inside the fixing cylinder 8. A fixing block 12 is fixed to the end face of the push rod 9 inside the wire ring 6 by screws. An arc groove is opened on the fixing block 12 to facilitate contact with the wire and fix the position of the wire.

[0031] A limiting ring 10 is fixed to the outside of the push rod 9 and is movably connected to the fixed cylinder 8. A support spring 11 for supporting the limiting ring 10 is sleeved on the outside of the push rod 9. Inclined grooves for the push rod 9 to move are opened on the inner walls of both sides of the adjusting ring 7. The part of the push rod 9 that contacts the adjusting ring 7 is a hemispherical structure, which allows the adjusting ring 7 to move more smoothly outside the push rod 9. A threaded hole is opened on the surface of the adjusting ring 7. A fixing bolt 13 is threaded into the threaded hole on the surface of the adjusting ring 7. By rotating the fixing bolt 13, the fixing bolt 13 is made to fit against the surface of the wire ring 6, which can fix the position of the adjusting ring 7 and prevent the adjusting ring 7 from moving accidentally. The wire passes through the wire ring 6 and is connected between connector 1 and connector 2. By moving the adjusting ring 7, the push rod 9 and the fixing block 12 can be driven to move simultaneously, so that the two fixing blocks 12 fit against both sides of the wire, which can fix the position of the wire. When external force is applied to the wire, the wire is prevented from separating from connector 1 and connector 2, thereby ensuring the stability of data transmission.

[0032] All standard parts used in this utility model can be purchased from the market, and irregular parts can be customized according to the description and drawings. The specific connection methods of each part adopt conventional methods such as bolts, rivets, and welding that are mature in the prior art. The machinery, parts and equipment adopt conventional models in the prior art, and the circuit connection adopts conventional connection methods in the prior art, which will not be described in detail here. The control method of this utility model is through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The contents not described in detail in this specification belong to the prior art known to those skilled in the art.

[0033] In the description of this utility model, it should be understood that the indicated orientation or positional relationship is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing this utility model and simplifying the description, and is not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0034] Working principle:

[0035] The securely fastened vehicle interface is used by inserting connector 1 and connector 2 together. The limiting post 3 is inserted into the moving groove of the limiting frame 4, and the limiting member 5 is inserted into the limiting groove of the limiting frame 4. Rotating the limiting frame 4 moves the limiting post 3 to the bottom of the moving groove on both sides of the limiting frame 4. At this time, the limiting member 5 and the limiting groove on the limiting frame 4 are misaligned, and the limiting frame 4 fixes the position of connector 2, preventing connector 2 from moving upward. Due to the misalignment of the limiting member 5 and the limiting groove on the limiting frame 4, the position of the limiting frame 4 is further restricted, preventing the limiting frame 4 from moving and ensuring the stability of the connection between connector 1 and connector 2. It also prevents the vibration caused by vehicle movement from causing displacement between connector 1 and connector 2, resulting in signal disconnection and inability to use the button normally, affecting the normal use of the car. Pushing the limiting buckle 14 on the surface of connector 2 moves the limiting buckle 14 into the slot of the limiting frame 4, further fixing the position of the limiting frame 4.

[0036] The wire passes through the wire ring 6 and connects to connector 1 and connector 2. Pushing the adjusting ring 7 moves the push rod 9 within the inclined groove of the adjusting ring 7, causing the push rod 9 and the fixing block 12 to move simultaneously. This causes the two fixing blocks 12 to simultaneously adhere to both sides of the wire, fixing its position. Rotating the fixing bolt 13 causes it to adhere to the surface of the wire ring 6, fixing the position of the adjusting ring 7. When external force is applied to the wire, the fixing blocks 12 fix its position, preventing the wire from separating from connector 1 and connector 2, thus ensuring the stability of data transmission.
