An oblique pin locking hose joint

Abstract

The invention relates to the technical field of automobile parts and provides a hose connector provided with slanting pins for locking. The hose connector comprises a shell. The shell is in the shapeof a stepped shaft, and a through hole is formed in the middle of the shell. A plane is tangentially arranged on the arc-shaped outer wall of a small-diameter cylinder of the shell, and the shell is cut along the vertical symmetry face of the plane to be evenly divided into an upper half part and a lower half part. One end of the upper half part is connected with one end of the lower half part, and the other end of the upper half part and the other end of the lower half part are clamped together in a matched mode. Semicircular grooves which are coaxial with the through hole are inwards formedin the section of the upper half part and the section of the lower half part correspondingly. Semicircular silica gel inner cores are clamped in the semicircular grooves. Clamping grooves are symmetrically formed in the middle of the arc-shaped outer wall of the small-diameter cylinder of the shell along the vertical symmetry face, and pin structures are clamped in the clamping grooves in a matched mode. According to the hose connector provided with the slanting pins for locking, a traditional process that a rubber ring is used for connecting a harness hose and a car body metal plate is replaced, so that the sealing performance is good, mounting is fast and convenient, fixation is firm, and the assembling efficiency is improved.

Description

Technical field[0001]The invention relates to the technical field of auto parts, in particular to an inclined pin locking hose joint.Background technique[0002]In the process of automotive wiring harness design, the wiring harness needs to pass through the body sheet metal hole from the cockpit to the outside of the cockpit. The sheet metal hole through which the wiring harness passes must have a waterproof sealing structure to ensure that water cannot escape from the sheet metal. The gap at the golden hole enters the cockpit. As the requirements for comfort, assemblability and durability of the entire vehicle increase, it is required to optimize the design structure of the entire vehicle body in the early design stage.[0003]At present, an integrated rubber ring is generally installed at the sheet metal hole. The wire harness passes through the through hole of the rubber ring. The waterproof function of the sheet metal hole can be improved by setting the rubber ring, but the existing...

AI Technical Summary

Problems solved by technology

[0003] At present, an integrated rubber ring is generally installed at the sheet metal hole, and the wiring harness passes through the hole of the rubber ring. The waterproof function of the sheet metal hole can be improved by installing the rubber ring, but currently only rely on the rubber ring to cooperate with the sheet metal hole. Positioning, in the process of assembling the wire harness to the vehicle, it takes a lot of effort to deform the rubber ring to assemble it in place, which consumes man-hours and is prone to improper assembly. The sound insulation effect is average, and the noise control in the cockpit is not good

[0004] Disadvantages of traditional technology using rubber rings to connect the wire harness hose to the body sheet metal: 1. The connector of the wire harness is generally twice the diameter of the hose, and the through hole of the body sheet metal can meet the passage of the connector, but the sealing of the hose And the fixing can only rely on the rubber ring. Due to the relatively large amount of compression, the installation of the rubber ring is time-consuming and laborious, and the protective effect is not good, so it is easy to be installed incorrectly; 2. The rubber ring is easily scratched by the cloak of the sheet metal mouth broken, causing safety hazards such as water ingress, and the pull-off force is small, and the bus is easily taken out after long-term bumpy driving, causing bad
