Description

Technical Field

[0001] The utility model relates to the technical field of automotive connection lines, in particular to an end fixing buckle structure for an automotive connection line. Background Technique

[0002] Automotive connection lines are an important component inside an automobile, mainly used for transmitting current to ensure the normal operation of various electrical devices in the automobile. In modern automobiles, the electronic control system is closely related to the vehicle wiring harness. The wiring harness is equivalent to the "nerves and blood vessels" of the automobile, ensuring that current and signals can be accurately and efficiently transmitted to various parts.

[0003] In order to fix the automotive connection line, fixing buckles are often provided at the end of the automotive connection line to fix the automotive connection line at the required position. Most of the existing fixing buckles for automotive connection lines clamp the connection line through elastic members. In order to prevent the connection line from loosening, a closing design is adopted at the bayonet, resulting in the need to forcefully insert the connection line into the card slot during the installation of the connection line, which easily causes the connection line to be damaged due to excessive extrusion, and the extrusion process is laborious and not convenient to use, and it is also easy to cause damage to the buckle. For this reason, an end fixing buckle structure for an automotive connection line is proposed for improvement. Content of the Utility Model

[0004] The purpose of the present utility model aims to solve at least one of the above technical defects.

[0006] To achieve the above object, an embodiment of one aspect of the present utility model provides an end fixing buckle structure for an automotive connection line, including a main ring, a front restraint ring and a rear restraint ring are respectively fixedly connected to the front end and the rear end of the main ring, a fixing plate is fixedly connected to the outer sides of the front restraint ring and the rear restraint ring, and a plurality of fixing holes are formed in the fixing plate;

[0007] A clamping air bag is fixedly connected inside the main ring, restraint portions are arranged at both ends of the clamping air bag, an exhaust pipe is fixedly connected to one side of the clamping air bag, an exhaust valve is arranged on the exhaust pipe, a protection frame is fixedly connected to the outer side of the main ring, an air bag is arranged inside the protection frame, an air delivery pipe is arranged between the air bag and the clamping air bag, a one-way valve is arranged on the air delivery pipe, a notch is formed in the protection frame, and an anti-slip pad is arranged inside the clamping air bag.

[0008] Preferably, the sizes of the front restraint ring and the rear restraint ring are not less than the size of the main ring, and the restraint portions are fixedly connected inside the front restraint ring and the rear restraint ring.

[0009] Preferably, according to any of the above solutions, the fixing plate is fixedly connected to the front restraint ring and the rear restraint ring respectively through two connecting plates.

[0010] Adopting the above technical solution: The main ring provides an installation platform for the relevant clamping structure. It adopts an annular structure, which is convenient for the automotive connecting wire to pass through. The front restraint ring and the rear restraint ring are used to restrain the restraint part, preventing the restraint part from extending outside the buckle structure after inflation. The front restraint ring and the rear restraint ring also protect the restraint part, preventing external objects from accidentally touching the restraint part and causing damage and air leakage of the restraint part. The fixing plate is used to fix the buckle structure on the relevant base. By using bolts or other tools in cooperation with the fixing holes, the fixation of the buckle structure can be achieved.

[0011] Preferably, according to any of the above solutions, the clamping airbag adopts an annular structure, and a heat insulation layer is arranged on the outer side of the clamping airbag.

[0012] Preferably, according to any of the above solutions, the exhaust pipe penetrates through the main ring, and the exhaust valve is arranged on the side of the main ring away from the fixing plate.

[0013] Adopting the above technical solution: The clamping airbag is used to fix the automotive connecting wire. In the non-use state, it is in a deflated state, and the space inside the main ring is relatively large, which is convenient for the connecting wire to be quickly inserted. After the connecting wire is inserted, the clamping airbag is inflated through relevant components, so that the clamping airbag completely fills the space between the connecting wire and the main ring, thus realizing the fixation of the connecting wire. A restraint part is arranged at the end of the clamping airbag, and the restraint part expands the influence range of the clamping airbag, improving the stability of the connecting wire. When the connecting wire moves laterally, the gas in the restraint part moves towards the middle position of the clamping airbag, making the clamping airbag clamp the connecting wire tighter, thus ensuring the stability when the outside of the connecting wire moves.

[0014] Preferably, according to any of the above solutions, the airbag adopts an annular structure, and the air supply pipe is arranged corresponding to the notch.

The protection frame can provide protection for the airbag from the outside, preventing external objects from accidentally touching and causing damage and air leakage of the airbag. The notch is provided for the user to press the airbag to inflate the clamping airbag. Arranging an anti-slip pad on the inner side of the clamping airbag is beneficial to increasing the friction force between it and the connecting wire, making the connecting wire more stable.

A constraint part is provided at the end of the clamping air bag, and the constraint part expands the influence range of the clamping air bag, improving the stability of the connecting wire. When the connecting wire moves laterally, the gas in the constraint part moves towards the middle position of the clamping air bag, causing the clamping air bag to clamp the connecting wire more tightly, thus ensuring the stability when the outside of the connecting wire moves. The gas in the clamping air bag can be filled and discharged as needed, facilitating the insertion and fixation of the connecting wire. The flexible fixation method of the clamping air bag greatly reduces the possibility of damage to the connecting wire, and the buckle structure is also safer and more reliable, with stronger practicability.
