Description

Technical Field

[0001] This utility model relates to a range hood wiring harness, specifically a range hood wiring harness with a sealing plug for the wire passage hole. Background Technology

[0002] To meet the demands of modern life, kitchen environments need to be kept clean and hygienic. Therefore, range hoods, as electrical appliances that effectively absorb and exhaust cooking fumes, are popular. In the manufacturing process of range hoods, the wiring harness connecting the control panel and its internal components is a crucial part of the range hood's normal operation. Traditionally, the wiring harness is inserted through holes created in various components. These holes are usually simple and slightly larger than the cross-sectional area of ​​the wiring harness, making insertion relatively easy. However, the cooking fumes inside range hoods contain a large amount of grease and moisture, and these holes lack sealing devices. This allows grease and moisture to easily enter the components through these holes. The strong adhesion and penetrability of grease can severely corrode components such as circuit boards, causing damage and affecting the normal operation of the range hood, thus shortening its lifespan.

[0003] Meanwhile, the simple insertion of holes does not secure the wire harness. During the long-term vibration of the fan, the wire harness is prone to loosening or displacement, which may lead to the wires falling off or the insulation layer wearing off and causing short circuits, further increasing the safety hazards. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of existing technologies and provide a range hood wiring harness with a wire hole sealing plug that has a simple structure, low manufacturing cost, good sealing performance, ensures that the wiring harness will not loosen or fall off, has a firm and stable connection, and extends the service life of the range hood.

[0005] The purpose of this utility model is achieved in the following way: a range hood wiring harness with a sealing plug for wire passage holes, which includes a sealing seat, and a plurality of wire passage holes are provided on the sealing seat through the front and rear end faces of its body, and the wiring harness is installed in the wire passage holes.

[0006] The sealing seat includes a cover plate and a retaining plate. The cover plate covers the mounting hole inside the range hood. The retaining plate and the cover plate meet to form a groove, which holds the mounting hole inside.

[0007] The groove is a "V"-shaped inner groove.

[0008] The cross-sectional area of ​​the groove is greater than or equal to the cross-sectional area of ​​the mounting hole.

[0009] The card holder has an inclined guide surface on its cylindrical surface, and the end area of ​​the guide surface is smaller than that of the mounting hole.

[0010] The card holder has a diamond-shaped cross-section, which is larger in the middle and smaller on both sides.

[0011] The sealing seat is made of flexible rubber.

[0012] The cross-sectional area of ​​the wire hole is smaller than that of the wire harness, and the two are in an interference fit.

[0013] The beneficial effects of this utility model are: 1. Simple structure, low manufacturing cost, and improved market competitiveness.

[0014] A sealing seat is installed to connect and fix the wiring harness, improving its sealing performance, effectively preventing oil fumes from entering the range hood, extending the range hood's service life, and ensuring its long-term stable operation.

[0015] The internal retainer of the sealing seat engages with the mounting hole to lock the sealing seat in place, ensuring that the wiring harness will not loosen or shift during use. This provides additional support and positioning for the wiring harness, minimizing the risk of the wiring harness coming loose due to fan vibration and ensuring the long-term stable operation of the range hood.

[0016] The sealing seat is made of rubber, which provides it with sufficient flexibility, making it easier and faster to install in the mounting hole, while ensuring its sealing performance. Attached Figure Description

[0021] The present invention will be further described in detail below with reference to the accompanying drawings. A range hood wiring harness with a sealing plug for wire passage holes includes a sealing seat 2, and a plurality of wire passage holes 3 are provided on the sealing seat 2 through the front and rear end faces of its main body, and the wiring harness 1 is installed in the wire passage holes 3;

[0022] The sealing seat 2 includes a cover plate 21 and a retainer 22. The cover plate 21 covers the outside of the mounting hole inside the range hood. The retainer 22 and the cover plate 21 are recessed to form a clamping groove 4, which clamps the mounting hole inside.

[0023] The clamping groove 4 is a "V" shaped inner groove.

[0024] The cross-sectional area of ​​the groove 4 is greater than or equal to the cross-sectional area of ​​the mounting hole.

[0025] The card holder 22 has an inclined guide surface 5 on its cylindrical surface, and the end area of ​​the guide surface 5 is smaller than that of the mounting hole.

[0026] The card holder 22 has a diamond-shaped cross-section that is larger in the middle and smaller on both sides.

[0027] The sealing seat 2 is made of flexible rubber.

[0028] The cross-sectional area of ​​the wire hole 3 is smaller than that of the wire harness 1, and the two are in an interference fit.

[0029] Working principle: In the installation of the wiring harness of the range hood, a sealing seat is set up to connect and fix it to the range hood. After the wiring harness passes through the wire hole opened in the sealing seat body, the terminal block is installed to connect to the control panel and other components. The cross-sectional area of ​​the wire hole is smaller than the cross-sectional area of ​​the wiring harness, and the wiring harness and the wire hole are connected by an interference fit. When the wiring harness is installed, the interference fit forms a tight connection between the wiring harness and the sealing seat, so that there is no gap between the wiring harness and the wire hole, improving the sealing performance and effectively preventing oil fumes from penetrating into the range hood through the wire hole.

[0030] The sealing seat includes a cover plate and a retaining bracket. The cover plate covers and engages with the mounting hole inside the range hood. A V-shaped recess is formed at the junction of the cover plate and the retaining bracket, clamping the mounting hole within this recess. To enhance the connection strength and improve sealing performance, the cross-sectional area of ​​the recess is set to be greater than or equal to the cross-sectional area of ​​the mounting hole. Simultaneously, the retaining bracket has a diamond-shaped cross-section, wider in the middle and narrower on both sides. Guided by the inclined guide surface of the retaining bracket, the mounting hole can only be engaged at the bottom of the recess, locking the sealing seat in place. This ensures that the wiring harness will not loosen or shift during use, providing additional support and positioning for the harness, minimizing the risk of harness loosening due to fan vibration, and ensuring the long-term stable operation of the range hood.

[0031] Furthermore, the sealing seat effectively prevents oil fumes from entering the components through the mounting hole, avoiding corrosion damage to circuit boards and other components caused by oil fume infiltration, and significantly improving the service life and operational stability of the range hood.

[0032] The aforementioned sealing seat is made of soft rubber, which gives it good flexibility and anti-aging properties. It can deform and return to its original position immediately when the wire harness is interference-fitted, further improving the sealing performance. Even in the long-term high-temperature and humid kitchen fume environment, the sealing seat still maintains good sealing performance and extends its service life, so it can be widely used.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
