Description

Technical Field

[0001] This utility model relates to the field of air conditioner accessories technology, specifically to an air conditioner wiring harness protective sleeve. Background Technology

[0002] As a core component of the air conditioning system, the outdoor unit of an air conditioner is exposed to a complex and harsh outdoor environment for a long time. Rainwater, dust and other external factors can enter the interior of the outdoor unit through the wiring holes, causing corrosion and short circuits in the internal wiring. Therefore, the wiring harness sheath must be designed with a seal to resist the above-mentioned environmental factors and ensure the long-term reliable operation of the wiring harness.

[0003] The wire guide hole of the cable sheath is usually press-fitted to the outside of the cable harness with an interference fit to achieve a sealing effect between the cable harness and the cable sheath. However, the inner diameter of the interference fit wire guide hole is smaller than the outer diameter of the cable harness, which makes it very troublesome during the cable harness threading process.

[0022] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0023] This utility model embodiment provides an air conditioner wiring harness protective sleeve, such as... Figure 1-3As shown, the sleeve body is inserted into the wiring hole of the air conditioner outdoor unit, and the wire harness passes through the middle of the sleeve body. The sleeve body includes a sleeve skeleton 1 and a rubber sleeve 2. The sleeve skeleton 1 includes an abutment ring 101 and a plug-in sleeve 102 extending forward from the abutment ring 101.

[0024] The front end of the plug-in sleeve 102 is provided with several partition grooves, and a support beam 3 is provided between two adjacent partition grooves. The support beams 3 together form a guide cylinder. The outer diameter of the guide cylinder is equal to the inner diameter of the wire hole of the air conditioner outdoor unit, so that the sleeve body can be smoothly slidably inserted into the wire hole. A deformation pressure ring 5 is slidably installed on the inner side of the guide cylinder. The inner wall of the front end of the support beam 3 has a positioning inner edge, which can limit the deformation pressure ring 5 at the front end and prevent the deformation pressure ring 5 from falling off the front side of the guide cylinder. The inner radius of the positioning inner edge is greater than or equal to the outer diameter of the wire harness, so that the wire harness can be smoothly inserted into the plug-in sleeve 102 and avoid the difficulty of wire harness insertion caused by interference fit. An elastic piece 4 extends in the partition groove. The inner diameter of the elastic piece 4 is greater than the inner diameter of the support beam 3. A deformation gap is provided between the inner wall of the elastic piece 4 and the outer wall of the deformation pressure ring 5 to provide displacement space for the elastic piece 4 to deform inward.

[0025] The outer edge of the elastic sheet 4 is connected to a conical surface. The outer diameter of the conical surface gradually increases from front to back. The front side of the conical surface is flush with the outer edge of the support beam 3, and the rear side of the conical surface protrudes from the outer edge of the support beam 3. During the process of inserting the connector 102 into the wiring hole of the air conditioner outdoor unit, the inner wall of the wiring hole will abut against and squeeze the conical surface, causing the elastic sheet 4 to deform inward. A snap-fit ​​ring groove 6 is provided on the rear side of the elastic sheet 4. A snap-fit ​​conical surface is provided on the bottom wall of the snap-fit ​​ring groove 6. The outer diameter of the snap-fit ​​conical surface gradually decreases from front to back, and the front side of the snap-fit ​​conical surface protrudes from the outer edge of the support beam 3. The rear side of the snap-fit ​​cone surface is flush with the outer edge of the support beam 3. When the wiring hole of the air conditioner outdoor unit slides to the snap-fit ​​ring groove 6, the elastic piece 4 jumps in the opposite direction and snaps onto the inner wall of the wiring hole of the air conditioner outdoor unit. This allows the sleeve body to be snapped and fixed inside the wiring hole of the air conditioner outdoor unit. At the same time, the snap-fit ​​cone surface on the inner wall of the wiring hole will keep the elastic piece 4 in an inwardly deformed state. The inner side of the elastic piece 4 has a recessed abutting protrusion ring 7. The abutting protrusion ring 7 has an abutting cone surface on the side facing the deformation pressure ring 5. The abutting cone surface slides and abuts against the front side of the deformation pressure ring 5. The front side of the deformation pressure ring 5 has a sliding chamfer.

[0026] The contact ring 101 has several positioning holes in its circumferential direction, and the inner wall of the contact ring is provided with positioning blocks 8 at intervals, with a gap groove between two adjacent positioning blocks 8.

[0027] The front side of the rubber sleeve 2 is provided with an interference-fit cylinder 9, which is fixed to the inner wall of the plug-in cylinder 102. The deformation pressure ring 5 abuts against the front side of the interference-fit cylinder 9. The inner diameter of the interference-fit cylinder 9 is greater than or equal to the outer diameter of the wire harness, which facilitates the insertion of the wire harness. The inner wall of the interference-fit cylinder 9 is provided with several positioning slots that mate with the positioning blocks 8. Several positioning blocks 8 form a rear support on the rear side of the interference-fit cylinder 9, so that when the deformation pressure ring 5 slides backward to squeeze the interference-fit cylinder 9, the interference-fit cylinder 9 can only expand and deform inward, so that it hugs and abuts against the outer side of the wire harness to form a seal.

[0028] The rubber sleeve 2 is provided with a sealing edge 10 in the middle. The sealing edge 10 has a sealing groove. The sealing edge 10 is bonded and covered to the outside of the contact ring 101. The sealing edge 10 is provided with a positioning post 11 that passes through the positioning hole. The sealing edge 10 can be used to abut against the front side of the wiring hole of the air conditioner outdoor unit to achieve a seal between the sleeve body and the wiring hole. At the same time, the sealing edge 10 and the snap ring groove 6 snap into the front and rear sides of the wiring hole so that the sleeve body can be snapped and fixed in the wiring hole without shaking.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
