Description

Technical Field

[0001] This utility model belongs to the field of wiring plug technology, and in particular relates to a connection mechanism for male and female plug mating. Background Technology

[0002] Male and female plugs are an important component of electrical connectors, used to achieve electrical connections between electrical devices. In industrial production, fans in the production workshop need to be wired and powered on before the high-temperature season and disconnected and powered off after the high-temperature season. Using male and female plugs for wiring can facilitate the connection and disconnection operations before and after the high-temperature season.

[0003] As disclosed in the utility model with authorization announcement number CN219610884U, a highly robust plug relates to the field of plug technology. It includes a male plug and a female plug, with a limiting mechanism and a locking mechanism between them. After the male and female plugs are connected, the male plug can be pushed towards the female plug, causing a first connecting post at one end of the male plug to insert into the interior of the female plug. The connecting key on the outer side of the first connecting post engages with the internal keyway of the female plug, connecting the male and female plugs together. During the connection process, pressing two locking strips reduces the distance between them, allowing the locking strips to pass through the interior of the female plug and engage in the slot using a locking block. This further limits the connection between the male and female plugs, making the connection even more secure. However, in the application of this technical solution, the male and female plugs are inserted by placing the keyway engagement. There are gaps at the keyway engagement and frequent wear and tear cause the engagement to be loose. This presents a technical problem that makes it impossible to conveniently, quickly, securely and tightly connect and fix the male and female plugs to achieve electrical connection between electrical equipment. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides a connection mechanism for male and female plug mating, which can effectively solve the problems of the existing technology.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This utility model is a connecting mechanism for male and female plugs, including a male plug and a female plug, and further including: a connecting wire provided on one side of the male plug and the female plug; a sealing ring provided on the outer side of the male plug; a fastening nut provided on the outer side of the male plug; a stabilizing sleeve fixedly connected to the outer side of the female plug; a heat shrink tube provided on the outer side of the connecting wire; and an anti-bending buffer component provided on the outer side of the male plug and the female plug.

[0007] Furthermore, the stabilizing sleeve is fitted onto the outside of the male plug, and the sealing ring has a circular cross-section.

[0008] Furthermore, the fastening nut is sleeved on the outside of the stabilizing sleeve, and the outer side of the stabilizing sleeve is provided with an external thread that mates with the inner thread of the fastening nut.

[0009] Furthermore, the end of the female plug fits into the inside of the end of the male plug, and the female plug and the male plug are inserted into each other.

[0010] Furthermore, the anti-bending buffer assembly includes a limiting sleeve, which is disposed on one side outside the male plug and the female plug. A buffer pad is provided on one side of the inner sidewall of the limiting sleeve, and a spring is provided on the other side of the inner sidewall of the limiting sleeve. A gasket is provided on the inner side of the spring.

[0011] Furthermore, the buffer pad is annular, the outer edge of the limiting sleeve is rounded, four sets of springs are provided, the springs are arranged at equal intervals on the other side of the inner sidewall of the limiting sleeve, the gasket is arc-shaped, and the inner side of the gasket is in contact with the outer side of the connecting line.

[0012] This utility model has the following beneficial effects:

[0013] 1. This utility model, by comprising a male plug, a female plug, a fastening nut, a stabilizing sleeve, and a heat shrink tube, allows for quick connection and disconnection of workshop fans before and after high-temperature seasons, improving work efficiency and reducing labor intensity. During use, the male plug is connected to the fan via a connecting cable, and the female plug is connected to the power cord. To connect the fan to a fire-resistant system, simply insert the male and female plugs and tighten the fastening nut onto the outside of the stabilizing sleeve. A sealing ring provides a protective seal at the connection point, and the heat shrink tube, when applied and heated, seals the connection. To disconnect the fan, simply loosen the fastening nut and unplug the connector. This design enables rapid connection and disconnection of workshop fans before and after high-temperature seasons, improving work efficiency and reducing labor intensity.

[0014] This utility model features an anti-bending buffer component on one side of both the male and female plugs. During use, a limiting sleeve restricts the connection between the connecting wire and the plug, preventing excessive bending of the wire harness at the connection point. The rounded edges of the limiting sleeve prevent damage to the wire harness. Additionally, springs and buffer pads cushion the connection when the wire is excessively bent, effectively preventing breakage or damage at the connection between the connecting wire and the plug during use, thus avoiding disruption to normal equipment operation or electrical leakage accidents. This further enhances the safety of the connection mechanism. Attached Figure Description

[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] Please see Figure 1-4As shown, this utility model is a connecting mechanism for male and female plugs, including a male plug 1 and a female plug 3, and further including: a connecting wire 4 provided on one side of the male plug 1 and the female plug 3, the end of the female plug 3 fitting inside the end of the male plug 1, the male plug 1 being connected to a fan via the connecting wire 4, and the female plug 3 being connected to a power cord, and the female plug 3 and the male plug 1 being plugged in; a sealing ring 7 with a circular cross-section is provided on one side of the outside of the male plug 1; a fastening nut 2 is provided on the outside of the male plug 1; a stabilizing sleeve 8 is fixedly connected to the outside of the female plug 3, the stabilizing sleeve 8 being sleeved on the outside of the male plug 1, and the fastening nut 2 being sleeved on the outside of the stabilizing sleeve 8. The outer side is provided with an external thread that matches the inner thread of the fastening nut 2. When connecting the fan, simply plug the male plug 1 and the female plug 3 into each other and tighten the fastening nut 2 to the outside of the stabilizing sleeve 8 to secure the plugs. The sealing ring 7 is used to seal and protect the connection. The outside of the connecting wire 4 is provided with a heat shrink tube 6. The heat shrink tube 6 is fitted onto the outside of the connection point and heated to shrink, which seals the plug connection. When disassembling the fan, simply loosen the fastening nut 2 and pull out the plug. This allows for quick connection and disassembly of the workshop fan before and after the high-temperature season, improving work efficiency and reducing labor intensity.

[0024] As a further implementation of this embodiment, such as Figure 1-4 As shown, an anti-bending buffer assembly is provided on one side of the male plug 1 and the female plug 3. The anti-bending buffer assembly includes a limiting sleeve 5, which is located on one side of the male plug 1 and the female plug 3. The outer edge of the limiting sleeve 5 is rounded. When the device is powered on and connected for use, the limiting sleeve 5 limits the connection between the connecting wire 4 and the plug, preventing excessive bending of the wire harness at the connection point. The rounded outer edge of the limiting sleeve 5 also prevents damage to the wire harness. A ring-shaped buffer pad 9 is provided on one side of the inner sidewall of the limiting sleeve 5. On the other side, there is a spring 10. There are four sets of springs 10. The springs 10 are arranged at equal intervals on the other side of the inner sidewall of the limiting sleeve 5. An arc-shaped gasket 11 is provided on the inner side of the spring 10. The inner side of the gasket 11 is in contact with the outer side of the connecting wire 4. The spring 10 and the buffer pad 9 are used to buffer when the connecting wire 4 is bent too much, thereby effectively preventing the connecting wire 4 from being broken due to excessive bending at the connection point with the plug during use, which may affect the normal operation of the equipment or cause leakage accidents, thereby further improving the safety of the connection mechanism.

[0025] When in use, the limiting sleeve 5 limits the connection between the connecting wire 4 and the plug to prevent the wire harness from bending excessively at the connection point. The outer edge of the limiting sleeve 5 is designed with rounded corners to prevent the wire harness from being cut. At the same time, the spring 10 and the buffer pad 9 are used to buffer when the connecting wire 4 is bent too much, thereby preventing the connection between the connecting wire 4 and the plug from being broken or damaged due to excessive bending during use.

[0026] Working principle: When using the connection mechanism, the male plug 1 is connected to the fan via the connecting wire 4, and the female plug 3 is connected to the power cord. When connecting the fan, simply plug the male plug 1 and the female plug 3 into each other, and tighten the fastening nut 2 onto the outside of the stabilizing sleeve 8 to secure the plugs. At the same time, the sealing ring 7 is used to seal and protect the connection point. The heat shrink tube 6 is then fitted onto the outside of the connection point and heated to shrink, thus sealing the plug connection. The limiting sleeve 5 limits the connection between the connecting wire 4 and the plug, preventing excessive bending of the wire harness at the connection point. The outer edge of the limiting sleeve 5 is rounded to prevent damage to the wire harness. The spring 10 and the buffer pad 9 provide cushioning when the connecting wire 4 is bent too much, thus preventing excessive bending and breakage at the connection between the connecting wire 4 and the plug during use. This ensures stable and safe connection to the fan. After the high-temperature season, simply loosen the fastening nut 2 and disconnect the plug to disassemble the fan.

[0027] The above are merely preferred embodiments of the present utility model and do not limit the present utility model. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present utility model.
