Description

Technical Field

[0001] This utility model relates to the field of air conditioning wiring harness technology, and in particular to a high-performance noise-reducing commercial air conditioning wiring harness. Background Technology

[0002] Air conditioning wiring harnesses are key components that connect the indoor and outdoor units of an air conditioner and various electrical components. They are responsible for power transmission, signal control, and safety protection, and are used to connect various electrical and control components to ensure the normal operation of the air conditioning system.

[0003] Existing air conditioning wiring harnesses have a relatively simple structure, and most of them can only provide basic protection for the wiring harnesses. They cannot play a role in noise reduction and sound insulation protection according to the needs of the usage environment. As a result, they cannot reduce the noise generated when the air conditioning system is working, nor can they provide a quieter and more comfortable indoor environment.

[0004] For example, in the prior art, the patent with authorization announcement number CN220984198U discloses a high-performance noise reduction air conditioner wiring harness. This wiring harness can effectively absorb conducted or propagated noise by setting external protective noise reduction components, reducing the transmission of noise. At the same time, the internal sound insulation shielding components can isolate the transmission of electrical noise, avoid mutual interference and resonance between wiring harnesses, and reduce the generation of noise. The first sealing joint component and the second sealing joint component can play a role in stable sealing and docking, so that the wiring harness body can be used stably and with high performance.

[0005] Although this wiring harness can effectively absorb noise generated by the conduction or propagation of the wiring harness, when the first and second sealing joint assemblies are connected to various parts of the air conditioner, the sealing connection is only achieved by mating the sealing ring and sealing sleeve. During the operation of the air conditioner, vibration can cause the joint to loosen, resulting in poor contact and unstable current transmission at the joint, thus causing noise generation. Therefore, a high-performance noise-reducing commercial air conditioner wiring harness is designed to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a high-performance noise-reducing commercial air conditioner wiring harness.

[0007] The technical problem to be solved by this utility model is to provide a high-performance noise-reducing commercial air conditioner wiring harness, which solves the problem in the prior art where the connector of the air conditioner wiring harness is easy to loosen, resulting in poor electrical connection, unstable current transmission, and noise generation.

[0008] This utility model provides a high-performance noise-reducing commercial air conditioner wiring harness, including a wiring harness body and connectors, wherein both ends of the wiring harness body are electrically connected to connectors.

[0009] The connector includes a plug rod, a docking cylinder, a noise-reducing sealing ring, and an annular groove. Multiple plug rods are fixedly installed at the left end of the connector. A docking cylinder is fixedly installed on the left side surface of the connector. A noise-reducing sealing ring is fixedly installed on the left side surface of the connector. An annular groove is formed in the center of the left side surface of the noise-reducing sealing ring.

[0010] Preferably, the noise-reducing sealing ring is made of elastic rubber, and the noise-reducing sealing ring and the left end of the connector are on the same vertical plane.

[0011] Preferably, the outer surface of the noise-reducing sealing ring is a frustum-shaped structure with a greater thickness on the left side and a smaller thickness on the right side, and the annular groove has a groove structure with the right end sealed.

[0012] Preferably, a limiting ring is fixedly provided on the left side of the outer surface of the docking cylinder, and an annular limiting groove matching the limiting ring is opened in the docking groove that docks with the plug.

[0013] Preferably, the wire harness body includes a protective layer, an insulating layer, a signal shielding layer, a porous sound insulation layer, a sound-absorbing filling layer, an inner protective sleeve, and wire harness core wires. The outermost surface of the wire harness body is provided with a protective layer. An insulating layer is fixedly disposed on the inner surface of the protective layer with adhesive. A signal shielding layer is fixedly disposed on the inner surface of the insulating layer with adhesive. A porous sound insulation layer is fixedly disposed on the inner surface of the signal shielding layer with adhesive. A sound-absorbing filling layer is filled on the inner surface of the porous sound insulation layer. Multiple inner protective sleeves are disposed within the sound-absorbing filling layer. Wire harness core wires are fixedly disposed within the inner protective sleeves.

[0014] Preferably, the porous sound insulation layer is made of wave-crest sound-absorbing sponge material, and the sound-absorbing filling layer is made of sound-absorbing cotton material.

[0015] Compared with the prior art, this utility model has at least the following beneficial effects:

[0016] 1. This utility model features a noise-reducing sealing ring. When the connector is inserted into the socket, the gas in the annular groove of the noise-reducing sealing ring is expelled by squeezing the ring. Then, the connector is inserted into the socket. After the noise-reducing sealing ring is released, it returns to its original state under the elastic force of the ring. At this time, the air pressure in the annular groove is low. Under the action of the external atmospheric pressure, the air is adsorbed at the socket, ensuring the stability after insertion and preventing the socket from loosening, which could lead to poor electrical performance. Furthermore, because there is less air in the annular groove, the current noise generated at the connector is less likely to pass through the annular groove, thus achieving a better noise reduction effect.

[0017] 2. By setting a limiting ring, after the connector is inserted into the mating groove, the limiting ring on the mating cylinder is engaged in the annular limiting groove in the mating groove, which further ensures the stability of the connector after insertion, prevents the connector from becoming loose, ensures stable current transmission, and reduces noise generation.

[0018] 3. This utility model has a signal shielding layer, which can effectively prevent interference and signal noise caused by electromagnetic radiation. The insulation layer can isolate the transmission of electrical noise, while the porous sound insulation layer can isolate the noise generated when the current flows in the wire harness core. The sound-absorbing filling layer can absorb the noise generated when the current flows in the core and helps to reduce internal vibration and resonance, further reducing the propagation of noise inside the wire harness.

Detailed Implementation

[0026] Example:

[0027] like Figures 1-4 As shown, an embodiment of this utility model provides a high-performance noise-reducing commercial air conditioner wiring harness, including a wiring harness body 1 and a connector 2, with the connector 2 electrically connected to both ends of the wiring harness body 1.

[0028] The connector 2 includes a plug rod 201, a docking cylinder 202, a noise-reducing sealing ring 203, and an annular groove 204. Multiple plug rods 201 are fixedly installed at the left end of the connector 2. The docking cylinder 202 is fixedly installed on the left side surface of the connector 2. The noise-reducing sealing ring 203 is fixedly installed on the left side surface of the outer surface of the connector 2. An annular groove 204 is opened in the center of the left side surface of the noise-reducing sealing ring 203.

[0029] In this embodiment, the noise reduction sealing ring 203 is made of elastic rubber, and the noise reduction sealing ring 203 and the left end of the connector 2 are on the same vertical plane, so that when the connector 2 is inserted, the noise reduction sealing ring 203 contacts the insertion point.

[0030] In this embodiment, the outer surface of the noise reduction sealing ring 203 is a frustum-shaped structure with a larger thickness on the left and a smaller thickness on the right, and the annular groove 204 has a groove structure with a closed right end, ensuring the overall smoothness of the connector 2.

[0031] With the noise-reducing sealing ring 203 in place, when the connector 2 is inserted into the socket, the gas in the annular groove 204 on the noise-reducing sealing ring 203 is expelled by squeezing the noise-reducing sealing ring 203. Then, the connector 2 is inserted into the socket. After the noise-reducing sealing ring 203 is released, it returns to its original state under the action of the elasticity of the noise-reducing sealing ring 203. At this time, the air pressure in the annular groove 204 is low. Under the action of the external atmospheric pressure, it is adsorbed at the socket, ensuring the stability after the socket is inserted and preventing the socket from becoming loose, which could lead to poor electrical performance. In addition, because there is little air in the annular groove 204, the current noise generated at the socket is not easy to pass through the annular groove 204, thus achieving a noise reduction effect. The noise reduction effect is better.

[0032] In this embodiment, a limiting ring 205 is fixedly provided on the left side of the outer surface of the docking cylinder 202, and an annular limiting groove matching the limiting ring 205 is opened in the docking groove that docks with the plug 2.

[0033] By setting a limiting ring 205, after the connector 2 is inserted into the docking groove, the limiting ring 205 on the docking cylinder 202 is engaged in the annular limiting groove in the docking groove, which further ensures the stability of the connector 2 after insertion, prevents the connector 2 from becoming loose, ensures stable current transmission, and reduces noise generation.

[0034] In this embodiment, the wire harness body 1 includes a protective layer 101, an insulating layer 102, a signal shielding layer 103, a porous sound insulation layer 104, a sound-absorbing filling layer 105, an inner protective sleeve 106, and a wire harness core wire 107. The outermost surface of the wire harness body 1 is provided with a protective layer 101. The inner surface of the protective layer 101 is fixedly provided with an insulating layer 102 by adhesive. The inner surface of the insulating layer 102 is fixedly provided with a signal shielding layer 103 by adhesive. The inner surface of the signal shielding layer 103 is fixedly provided with a porous sound insulation layer 104 by adhesive. The inner surface of the porous sound insulation layer 104 is filled with a sound-absorbing filling layer 105. Multiple inner protective sleeves 106 are provided inside the sound-absorbing filling layer 105. The wire harness core wire 107 is fixedly provided inside the inner protective sleeve 106.

[0035] In this embodiment, the porous sound insulation layer 104 is made of wave crest sound-absorbing sponge material, and the sound-absorbing filling layer 105 is made of sound-absorbing cotton material.

[0036] By providing a signal shielding layer 103, the signal shielding layer 103 can effectively prevent interference and signal noise caused by electromagnetic radiation. The insulation layer 102 can isolate the transmission of electrical noise, while the porous sound insulation layer 104 can isolate the noise generated when the current flows in the wire harness core. The sound-absorbing filling layer 105 can absorb the noise generated when the current flows in the core and helps to reduce internal vibration and resonance, further reducing the propagation of noise inside the wire harness.

[0037] The above are merely preferred embodiments of this utility model. It should be noted that, for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model, and these should also be considered within the scope of protection of this utility model. These will not affect the implementation effect of this utility model or the practicality of the patent.
