CN-224233017-U - Wire harness for vehicle body air conditioner

Abstract

The utility model discloses a wire harness for an air conditioner of a vehicle body, which comprises a wire harness connector and a connecting seat which are connected with each other, wherein a connecting ring which is arranged on the periphery of the connecting seat in a surrounding way is arranged on the wire harness connector, one end of the connecting ring, which is close to the wire harness connector, is provided with a through hole, the wall of the through hole is also provided with a mounting groove communicated with the through hole, the inner wall of the mounting groove is provided with a clamping piece, a slidable sealing piece is arranged on the wire harness connector, the outer wall of the sealing piece is provided with an elastic lug, and the elastic lug protrudes towards the direction deviating from the sealing piece. The elastic lug is made of metal materials, when relative vibration is generated between the elastic sealing element and the connecting ring, vibration energy between the elastic lug can be absorbed through deformation of the elastic lug, abrasion of the connecting ring is reduced, and the elastic lug can be abutted against the inner wall of the mounting groove after elastic deformation even if the connecting ring is worn, so that relative displacement between the sealing element and the connecting ring is avoided.

Description

Wire harness for vehicle body air conditioner Technical Field The application relates to the technical field of devices for facilitating connection or disconnection of connecting parts or devices for keeping the connecting parts in a connected state, in particular to a wire harness for an air conditioner of a vehicle body. Background The invention patent application document with the publication number of CN119182020A describes a special connecting wire harness for a vehicle-mounted air conditioner of a commercial vehicle, the special connecting wire harness comprises a wire body and a wire harness end, the wire body is connected with the wire harness end, the wire body penetrates through a wiring hole of a wire harness end connecting seat, the wire seat is positioned in a wiring ring, an exhaust groove is formed in the joint of the wiring ring and the wire harness end, a sliding groove is formed in the position, corresponding to the exhaust groove, of the wire harness end, and a negative pressure resistance increasing structure is arranged in the sliding groove in a sliding mode. Because the negative pressure resistance-increasing structure is clamped into the exhaust groove after sliding, the socket of the vehicle-mounted air conditioner is clamped into the wire connecting ring and the socket to extrude internal air pressure to form negative pressure, and the situation that air is easy to loosen due to the fact that the wire harness end is inserted into the socket of the vehicle-mounted air conditioner. Through the structure, the contact part of the wire connecting ring and the negative pressure resistance increasing structure needs to be maintained to keep the airtight state so as to keep the negative pressure, the processing precision requirement is high, the wire connecting ring and the negative pressure resistance increasing structure mainly achieve position fixing through friction force between the wire connecting ring and the negative pressure resistance increasing structure, however, the automobile can cause micro-motion abrasion of the wire connecting ring and the negative pressure resistance increasing structure in a vibration environment in the driving process, gaps can be formed between the wire connecting ring and the negative pressure resistance increasing structure, the negative pressure is difficult to maintain between the wire connecting ring and the connecting seat, relative displacement can be generated between the wire connecting ring and the negative pressure resistance increasing structure due to reduction of friction force, and the connection stability of the wire connecting ring and the negative pressure resistance increasing structure is affected.
