Description

Technical Field

[0001] This application relates to the technical field of devices for facilitating the engagement or disconnection of connected components or devices for maintaining them in an engaged state, and more specifically to a wiring harness for vehicle body air conditioning. Background Technology

[0002] Patent application CN119182020A discloses a dedicated wiring harness for commercial vehicle air conditioning systems, comprising a wire body and a wiring harness end. The wire body is connected to the wiring harness end, and the wire body passes through a wiring hole in a connector for the wiring harness end. The connector is located inside a wiring ring. An exhaust groove is provided at the connection between the wiring ring and the wiring harness end, and a sliding groove is provided on the wiring harness end corresponding to the exhaust groove. A negative pressure resistance-increasing structure slides inside the sliding groove. Because the negative pressure resistance-increasing structure slides and engages in the exhaust groove, it compresses the internal air pressure after the vehicle air conditioning connector is engaged with the wiring ring and connector, creating a negative pressure and preventing air from remaining inside the wiring harness end after it is inserted into the vehicle air conditioning connector, thus preventing it from becoming loose.

[0003] The above structure requires maintaining an airtight connection between the connector ring and the negative pressure resistance-increasing structure to maintain negative pressure, which necessitates high machining precision. The connector ring and the negative pressure resistance-increasing structure are mainly fixed in position through friction between them. However, during vehicle operation, the connector ring and the negative pressure resistance-increasing structure will experience fretting wear under vibration, which may lead to gaps between them. This makes it difficult to maintain negative pressure between the connector ring and the connector, causing relative displacement between them due to reduced friction, thus affecting the connection stability. Utility Model Content

[0004] This utility model aims to solve at least one of the technical problems existing in the prior art. To this end, this utility model proposes:

[0005] A wiring harness for vehicle air conditioning includes a wiring harness connector and a connector base that are interconnected. The wiring harness connector has a connecting ring that is arranged around the periphery of the connector base. One end of the connecting ring near the wiring harness connector has a through hole. The wall of the through hole also has a mounting groove communicating with it. The inner wall of the mounting groove has a snap-fit ​​element. A slidable seal is installed on the wiring harness connector. The outer wall of the seal has an elastic protrusion that protrudes in a direction away from the seal.

[0006] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the cross-section of the snap-fit ​​component is V-shaped.

[0007] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the two ends of the elastic protrusion are respectively connected to the sealing member, and the sealing member is provided with a groove between the two ends of the elastic protrusion, and the snap-fit ​​member can extend into the groove.

[0008] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the through hole is provided with the mounting groove in the middle, the mounting groove is provided with the snap-fit ​​member on both sides of the groove wall, and the sealing member is provided with the elastic protrusion on both the inner and outer side walls.

[0009] The technical solution adopted by one embodiment of this utility model to solve its technical problem is as follows: the sealing element includes a sealing part and a pushing part connected to each other, the wire harness connector is provided with a groove communicating with the through hole, the wire harness connector is provided with a through hole communicating with the groove, the sealing part is disposed in the groove, and the pushing part is disposed outside the wire harness connector.

[0010] The technical solution adopted by one embodiment of this utility model to solve its technical problem is: the end of the mounting groove near the through hole is a tapered structure, and the cross-sectional area of ​​the tapered structure gradually decreases from the opening of the mounting groove to its bottom.

[0011] The beneficial effects of this utility model are:

[0012] After the wiring harness for the vehicle air conditioning described in this application is inserted into the corresponding plug of the vehicle air conditioning unit, the air between the wiring ring and the connector flows out through the through hole. At this time, the sealing member is slid into the through hole and the mounting groove, and the elastic protrusion abuts against the groove wall in the mounting groove, so that the sealing member is stably abutted against the inner wall of the mounting groove, thereby achieving stable installation of the sealing member. The snap-fit ​​member abuts against the elastic protrusion, thereby limiting the elastic protrusion and the sealing member in the through hole and the mounting groove, preventing the sealing member from being displaced relative to the connecting ring under the vibration of the vehicle during driving.

[0013] The elastic tab is made of metal. When relative vibration occurs between the elastic seal and the connecting ring, the elastic tab can absorb the vibration energy between them through deformation, reducing the wear of the connecting ring. Even after the connecting ring wears down, the elastic tab can still elastically deform and abut against the inner wall of the mounting groove, thereby preventing relative displacement between the seal and the connecting ring.

[0024] Reference Figure 1-5This application proposes an embodiment of the vehicle body air conditioning wiring harness, which includes a wiring harness connector 10 and a connector seat 20 connected to each other. The wiring harness connector 10 is provided with a connecting ring 30 surrounding the connector seat 20. One end of the connecting ring 30 near the wiring harness connector 10 is provided with a through hole 31. The wall of the through hole 31 is also provided with a mounting groove 32 communicating with it. The inner wall of the mounting groove 32 is provided with a snap-fit ​​member 33. A slidable sealing member 40 is installed on the wiring harness connector 10. The outer wall of the sealing member 40 is provided with an elastic protrusion 50, and the elastic protrusion 50 protrudes in a direction away from the sealing member 40.

[0025] The wire harness connector 10 is provided with a connection hole, and the connector 20 is provided with a wiring hole. The wire core of the wire harness passes through the connection hole and is fixed in the wiring hole by a conductive sleeve.

[0026] After the vehicle air conditioning wiring harness described in this application is inserted into the corresponding plug of the vehicle air conditioner, the air between the wiring ring and the connector 20 flows out through the through hole 31. At this time, the sealing member 40 is slid in and slides into the through hole 31 and the mounting groove 32. The elastic protrusion 50 abuts against the groove wall of the mounting groove 32, and the sealing member 40 is stably abutted against the inner wall of the mounting groove 32, so as to achieve stable installation of the sealing member 40. The sealing member 40 is also pressed against the elastic protrusion 50 by the snap-fit ​​member 33, so that the elastic protrusion 50 and the sealing member 40 are limited in the through hole 31 and the mounting groove 32, so as to prevent the sealing member 40 from being relatively displaced from the connector 30 when the vehicle is vibrating.

[0027] The elastic tab 50 is made of metal. When relative vibration occurs between the elastic seal 40 and the connecting ring 30, the elastic tab 50 can absorb the vibration energy between them through deformation, reducing the wear of the connecting ring 30. Even after the connecting ring 30 is worn, the elastic tab 50 can still elastically deform and abut against the inner wall of the mounting groove 32, thereby preventing relative displacement between the seal 40 and the connecting ring 30.

[0028] Referring to the accompanying drawings, the cross-section of the snap-fit ​​component 33 is V-shaped to ensure the stability of the snap-fit ​​structure.

[0029] Preferably, the two ends of the elastic protrusion 50 are respectively connected to the sealing member 40, and the sealing member 40 is provided with a groove 41 between the two ends of the elastic protrusion 50, and the snap-fit ​​member 33 can extend into the groove 41.

[0030] The elastic tab 50 will deform into the connecting ring 30 under the action of the snap fastener 33. The groove 41 provides space for the elastic tab 50 to deform downward in the middle, so that the elastic tab 50 can deform sufficiently on both sides of the groove 41, and ensure that the elastic tab 50 can protrude outward from the connecting ring 30 on both sides of the groove 41 and abut against the mounting groove 32.

[0031] The mounting groove 32 is provided in the middle of the bottom wall of the through hole 31. The snap-fit ​​member 33 is provided on both sides of the mounting groove 32. The elastic protrusion 50 is provided on both the inner and outer side walls of the sealing member 40, thereby improving the connection stability between the sealing member 40 and the connecting seat 20.

[0032] In this embodiment, the sealing element 40 includes a sealing part 42 and a pushing part 43 connected to each other. The wire harness connector 10 is provided with a sliding groove 11 communicating with the through hole 31 and a through hole 12 communicating with the sliding groove 11. The sealing part 42 is disposed in the sliding groove 11, and the pushing part 43 is disposed outside the wire harness connector 10, so that when the connector 20 is inserted into the plug, the pushing part 43 is pushed to move the sealing part 42 into the mounting groove 32.

[0033] Preferably, the end of the mounting groove 32 near the through hole 31 is a tapered structure 34, and the cross-sectional area of ​​the tapered structure 34 gradually decreases from the opening of the mounting groove 32 towards its bottom. When the sealing member 40 is pushed into the mounting groove 32, the sealing member 40 smoothly enters the mounting groove 32 guided by the tapered structure 34.

[0034] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
