Description

Technical Field

[0001] The present application relates to the field of plugs, and in particular to a fan quick plug structure. Background Art

[0002] Fans are widely used in electronic equipment, computers, servers, industrial equipment, and household appliances, primarily for heat dissipation and ventilation. Existing fans have an integrated, non-detachable wiring harness, with the power cord typically soldered directly to the fan's internal circuit board, making installation inconvenient. The integrated wiring harness also makes it difficult to adjust the length of the harness, making it cumbersome to use.

[0003] Existing detachable external cables have plugs that are either vertical or shaped like a figure 7. When the plug is vertical, the fan interface is tilted at an angle, making it difficult for installers to apply force when plugging in the external cable, making installation and removal more difficult. Furthermore, the vertical plug's wiring extends lengthwise, resulting in a larger installation space for the fan external cable, limiting its applicability and making it unsuitable for confined spaces. When the plug is shaped like a figure 7, the bent wire harness can be squeezed and deformed by the fan housing, causing the end of the harness connecting to the plug to break easily, shortening the harness's lifespan. Utility Model Content

[0029] The following is combined with Figure 1-Figure 5 This application is described in further detail.

[0030] The embodiment of the present application discloses a fan quick plug structure. Figure 1 and Figure 2 The fan assembly comprises a plug-in connector 1 and a transition portion 2, which are integrally formed. In this embodiment, the plug-in connector 1 and the transition portion 2 are formed by injection molding. The plug-in connector 1 is used to connect to the fan's plug interface, and the transition portion 2 is used to guide the wiring harness and reduce the overall installation space of the plug. When the fan is installed in a confined space, the transition portion 2 can also serve as a reminder to the installer of the installation position.

[0031] Reference Figure 1 and Figure 3 The connector 1 and the transition 2 are bent, with the angle between the horizontal extension line a on the transition side of the transition 2 and the horizontal extension line b on the transition side of the connector 1 forming a 45-degree angle. The angle c between the connector 1 and the other side of the transition 2 forms a 135-degree angle. The 45-degree angle effectively reduces the space required for the fan plug inside the cabinet and provides a foolproof effect, reminding the installer of the installation direction and reducing manual installation errors.

[0032] Reference Figure 1 and Figure 2The plug-in portion 1 is provided with a protrusion 3 on the side facing the fan structure. The protrusion 3 effectively prevents the plug from being too tight. In the embodiment of the present application, the protrusion 3 is arc-shaped on the side away from the plug-in portion 1, which facilitates quick plugging and unplugging of the plug. A positioning block 4 is provided on the end of the turning portion 2 away from the plug-in portion 1. The positioning block 4 is provided with a through hole 5 for the wiring harness to pass through. After the wiring harness passes through, in order to improve the strength of the connection between the wiring harness and the positioning block 4, a protective cover 6 is provided on the positioning block 4, which is located in the through hole 5 and is sleeved on the wiring harness. The inner wall corners of the protective cover 6 that contact the wiring harness are rounded, which reduces the pressure of the protective cover 6 on the wiring harness and reduces the degree of extrusion of the protective cover 6 on the surface of the wiring harness. In the embodiment of the present application, the protective cover 6 can be integrally formed with the positioning block 4 or detachable. When the protective cover 6 is detachable, an embedding block is provided on the end of the protective cover 6 that is inserted into the positioning block 4. The positioning block 4 is provided with an embedding groove for the embedding block to be embedded. The protective cover 6 is made of elastic material as a whole, which facilitates the embedding block to be embedded in the positioning block 4.

[0033] Reference Figure 2 and Figure 3 Several anti-slip blocks 7 are provided on the sidewalls of the transition portion 2. In this embodiment, the anti-slip blocks 7 are integrally formed with the transition portion 2, improving the stability of the anti-slip blocks 7 on the transition portion 2 and enhancing the anti-slip effect of the transition portion 2. The anti-slip blocks 7 are arrow-shaped, and the ends of the arrows can be arc-shaped or pointed. The arrow shape of the anti-slip blocks 7 in this embodiment of the application is consistent with the plug insertion direction and can also serve as an indicator.

[0034] The implementation principle of a fan quick plug structure in the embodiment of the present application is as follows: Figure 4 The plug part 1 is directly plugged into the plug interface of the fan and other structures, and the turning part 2 guides the turning direction of the wire harness and reminds the installer of the installation direction to avoid Figure 5 In this state, protrusion 3 facilitates quick removal of the plug by the installer, preventing the plug from being too tightly pressed against the interface. Anti-sliding block 7 increases friction on the transition portion 2, making it easier for the installer to pick up and install or remove the plug. Furthermore, the 45-degree angle between the transition portion 2 and the plug portion 1 of this application effectively saves installation space and expands the plug's applicability.

[0035] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
