[0001] This utility model relates to the field of fan shroud technology, specifically to an integrated fan shroud. Background Technology

[0002] The fan cover mainly refers to the outer casing of the fan. The junction box used to supply power to the motor is usually installed arbitrarily on the fan cover, which leads to unstable installation of the junction box. In addition, the existing junction boxes have poor waterproof and dustproof capabilities, which can easily cause dangers such as short circuits. Utility Model Content

[0003] The purpose of this invention is to provide an integrated wind shield that overcomes the shortcomings of the prior art.

[0004] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0005] An integrated fan cover includes a housing with a junction box on it. The junction box and the housing are connected by a connecting cover. The connecting cover is mounted on the outer surface of the housing. A sealing gasket is also provided between the connecting cover and the junction box. The outer surface of the sealing gasket is also provided with a protrusion that protrudes into the junction box. A wire through hole is provided in the middle of the protrusion. The sealing gasket seals the connection between the connecting cover and the junction box.

[0006] Furthermore, the junction box includes an upper box and a lower box that cooperate with each other. The connecting surface between the lower box and the upper box is an inclined surface, which is located at one of the diagonal positions of the junction box formed by the upper box and the lower box.

[0007] Furthermore, a wiring board is also installed inside the lower box, and a wiring space is formed between the lower surface of the wiring board and the protrusion, and a terminal post is provided on the upper surface of the wiring board.

[0008] Furthermore, the lower housing is also provided with a wiring hole, and a wiring head is installed on the wiring hole.

[0009] Compared with the prior art, the implementation effects of this utility model are as follows:

[0010] The junction box of the shroud is integrated with the shroud housing, and the junction box and the connecting cover are sealed together by a gasket, which can effectively improve the junction box's shock resistance, dustproof and waterproof capabilities. In addition, the connection surfaces of the upper and lower boxes of the junction box are beveled, which facilitates the installation and wiring of the wiring board and makes it easier for later maintenance.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] In the description of this utility model, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] like Figure 1-6As shown, the integrated fan cover of this utility model includes a cover 5 for installing a fan. The cover 5 is provided with a junction box. The junction box includes an upper box body 2 and a lower box body 1 that cooperate with each other. The connecting surface between the lower box body 1 and the upper box body 2 is an inclined surface. The inclined surface is located at one of the diagonal positions of the junction box formed by the upper box body 2 and the lower box body 1. The inclined surface setting facilitates the installation of the wiring board 6 inside the junction box and the connection of wires. The wiring board 6 is installed inside the lower box body 1.

[0022] The junction box and the housing 5 are connected by a connecting cover 4. The connecting cover 4 is installed on the outer surface of the housing 5. A rubber sealing gasket 3 is also provided between the connecting cover 4 and the junction box. The rubber sealing gasket 3 can be deformed by compression. The outer surface of the sealing gasket 3 is also provided with a protrusion 31 that protrudes into the lower box 1. Two wire holes 32 are provided in the middle of the protrusion 31. The sealing gasket 3 seals the connection between the connecting cover 4 and the junction box. The protrusion 31 has a limiting left and right position. Under the compression of the lower box 1 and the connecting cover 4, it can seal the lower box 1 around the protrusion 31. The wire holes 32 can also be compressed and their inner diameter can increase when wires are inserted, so that they can seal the wires around them.

[0023] After the junction box 6 is installed inside the lower box 1, a wiring space is formed between the lower surface of the junction box 6 and the protrusion 31. The upper surface of the junction box 6 is provided with terminal posts 7, which facilitates the connection of wires entering the junction box through the wire hole 32. The lower box 1 is also provided with wiring holes, on which terminal heads 11 are installed, which facilitates the connection and fixation of external wires introduced into the junction box.
