Abstract

The IP68-level double through-wall sealing mechanism includes a through-wall harness, a wall and a connector. A through-hole is opened on the wall, and the through-wall harness passes through the through-hole and is fixedly connected to the wall through the connector. The through-hole on the wall is a threaded hole, and the connector is a sleeve with a boss on the outer wall. The outer wall of the front pipe section of the connector boss is provided with a thread that matches the thread of the through-hole on the wall. The connector is screwed on the wall through the thread of the front section, and the front of the connector boss is pressed with the wall. A wall sealing rubber ring is provided in front of the connector outer wall boss. The inner wall of the connector is matched with the through-hole harness gap, and a harness sealing rubber ring is provided on the inner wall of the connector. The harness sealing rubber ring and the through-hole harness are interference-fitted. The beneficial effects are: through the double sealing structure, the IP68-level sealing of the through-hole harness is achieved; the sealing structure has good sealing effect against vibration and hot and cold shocks; the assembly process is simple, and the efficiency and safety are high.

Description

IP68 double over-wall sealing mechanism

technical field

The utility model belongs to the technical field of machinery, and in particular relates to the sealing of through-hole pipes, wires and the like.

Background technique

The through-hole sealing mechanism is mainly to solve the sealing problem between the through-wall pipeline and the hole-opening part. Usually, one side of the sealing connector is used to contact and seal the hole-opening part, and the other side is in contact with the through-hole pipeline for sealing.

In the prior art, there are mainly two structures for the sealing mechanism between the through-hole pipeline and the opening hole: one is to apply a sealant to seal between the through-hole pipeline and the opening hole. The feature is that it is easy to install, but the disadvantage is that it has poor stability and is not easy to disassemble. The other is to seal with a sealed joint. The feature is that it can solve the sealing problem, but the disadvantage is that the mechanism is complicated, the fixation is difficult, and the sealing ability is reduced in the environment of vibration and thermal shock.

Contents of the invention

The purpose of the utility model is to provide an IP68-level double-wall sealing mechanism to overcome the deficiencies of the prior art.

The technical scheme of the utility model is: an IP68 double wall-passing sealing mechanism, including a wall-passing harness, a wall and a connecting piece, a through hole is opened on the wall, and the connecting piece of the passing-wall wiring harness passes through the hole and is fixedly connected to the wall. The via hole on the wall is a threaded hole, the connector is a casing with a boss on the outer wall, and the outer wall of the front pipe section of the boss of the connector is provided with a screw thread that matches the thread of the via hole on the wall. The piece is screwed on the wall through the thread of the front section, the front of the boss of the connecting piece is pressed against the wall, the front of the boss of the outer wall of the connecting piece is provided with a wall sealing rubber ring, the inner wall of the connecting piece is matched with the via hole harness, and the inner wall of the connecting piece is A wire harness sealing rubber ring is provided, and the wire harness sealing rubber ring and the through-hole wire harness are interference fit.

The IP68-level double wall-passing sealing mechanism of the utility model is characterized in that there are two wiring harness sealing rubber rings, which are evenly arranged along the axial direction of the connecting piece.

The principle of the utility model is: the sealing between the connecting piece and the through-hole wiring harness is realized through two wire harness sealing rubber rings, and the sealing between the connecting piece and the wall is realized through the wall sealing rubber ring.

The beneficial effects are:

1. Through the double sealing structure, the IP68 level sealing of the through-hole wiring harness is realized;

2. The sealing structure has good sealing effect against vibration and thermal shock;

3. The assembly process is simple, and the efficiency and safety are high.
