Technical Field
[0001] The present application relates to the technical field of bathroom equipment connecting plugs, and in particular to a connecting plug. Background Art
[0002] As people's living standards are getting higher and higher, more and more people are using smart bathroom products (such as smart showers, smart toilets, etc.). When using smart bathroom products, an external power adapter is generally required to step down and stabilize the 220V AC power supply, and then output it to the power input socket of the smart bathroom product through the plug line of the power adapter.
[0003] Among them, the connection plug is a common component in the bathroom, which is used to realize the electrical connection between devices to achieve the purpose of transmitting current or signals. In order to achieve the effect of dustproof and waterproof, the traditional connection plug usually chooses to set a sealing ring inside the plug, relying on the sealing ring to ensure the sealing of the connection.
[0004] With regard to the above-mentioned related technologies, the design relying on the sealing ring increases the structural complexity and manufacturing cost of the connecting plug, and thus needs to be improved. Utility Model Content
[0005] In order to simplify the structure of the connecting plug, reduce the manufacturing cost, and maintain or improve the waterproof and dustproof effects, the present application provides a connecting plug.
[0006] The present application provides a connecting plug adopting the following technical solution:
[0007] A connecting plug, comprising a male connector and a female connector, wherein one end of the male connector is open and has a receiving cavity, and the male connector is connected to a plurality of cores parallel to each other, each of which is located in the receiving cavity and extends in the depth direction of the receiving cavity;
[0008] The female connector is connected with an insert block, which is inserted into the accommodating cavity; a plurality of mounting holes are provided at one end of the insert block facing the accommodating cavity, a core sleeve is connected in the mounting holes, and each core body is respectively inserted into each core sleeve.
[0009] By adopting the above technical solution, the plug block is inserted into the accommodating cavity, and the male connector and the female connector are detachably connected by the friction force; at the same time, each core body is respectively inserted into each core sleeve, and the core body serves as a metal terminal to achieve electrical connection. By adopting the male-female plug-in design, there is no need to use a sealing ring; at the same time, by the sinking design of the core body, each core body and the opening at the end of the male connector form a certain height difference. This design simplifies the structure of the traditional connection plug, reduces the manufacturing cost, and ensures waterproof and dustproof performance.
[0010] Preferably, the male connector is further provided with a limit block, which is located in the accommodating cavity and extends along the length direction of the core body.
[0011] By adopting the above technical solution, after the plug-in block is inserted into the accommodating cavity, the presence of the limit block can limit the circumferential rotation of the plug-in block, thereby improving the connection stability of the male connector and the female connector.
[0012] Preferably, the length of the limit block is lower than the cavity depth of the accommodating cavity, so that the end face of the limit block and the end face of the male connector form a step shape, and the length of the limit block is greater than the length of the core body; a stop block is connected to the plug block, and when the female connector is plugged into the male connector, the stop block abuts against the limit block.
[0013] By adopting the above technical solution, when the female connector is plugged into the male connector, the stopper will abut against the limit block to shield the limit block, thereby further reducing the possibility of dust and water contacting the core.
[0014] Preferably, the core is made of copper-nickel-plated material.
[0015] By adopting the above technical solution, the surface of the copper-nickel-plated material has strong corrosion resistance and also has the characteristics of good contact and conductivity.
[0016] Preferably, the male connector and the female connector are both injection molded with polyvinyl chloride insulating rubber.
[0017] By adopting the above technical solution, the male connector and the female connector are encapsulated by extrusion injection molding, which has the effect of insulation and fixed structure, thereby improving the safety of use.
[0018] Preferably, the end surface of the core sleeve is lower than the end surface of the insert block.
[0019] By adopting the above technical solution, the end face of the core sleeve is lower than the end face of the plug block, which can reduce the possibility of water and dust contacting the core sleeve and improve the waterproof and dustproof performance of the connecting plug.
[0020] Preferably, a plurality of anti-slip strips are arranged on the outer surface of the insert block, and the anti-slip strips are spaced apart along the insertion direction of the insert block.
[0021] By adopting the above technical solution, the anti-slip strip can increase the roughness of the outer surface of the plug block, increase the friction between the female connector and the male connector, and further improve the connection stability after the two are plugged in.
[0022] Preferably, both the male connector and the female connector are provided with convex strips.
[0023] By adopting the above technical solution, the presence of the convex strips can increase the roughness of the surfaces of the male connector and the female connector, making it easier for users to hold and apply force.
[0024] In summary, the present application includes at least one of the following beneficial technical effects:
[0025] (1) By simplifying the structure of the connection plug, the manufacturing cost is reduced. At the same time, the sinking design of the core of the male connector and the injection molding process are used to achieve a waterproof and dustproof effect equivalent to the existing technology, which can meet the requirements of IPX67 level. When used for a long time in a humid environment, the metal terminal will not oxidize. After oxidation, the contact resistance will increase, resulting in poor contact of the product. This design not only improves the cost performance of the product, but also helps to reduce maintenance costs and improve product reliability.
[0026] (2) By arranging a limit block in the accommodating cavity, the limit block can limit the circumferential rotation of the plug block, thereby improving the stability of the male connector and the female connector.
[0027] (3) By providing an anti-slip strip, the anti-slip strip can increase the roughness of the outer surface of the plug block and increase the friction between the female connector and the male connector. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Some embodiments of the present application are described in detail below in conjunction with the accompanying drawings. In the absence of conflict, those skilled in the art may combine and combine different embodiments or examples and features of different embodiments or examples shown in the present application.
[0037] The present application embodiment discloses a connecting plug. Figure 1 and Figure 2The connecting plug includes a male connector 1 and a female connector 2. Both the male connector 1 and the female connector 2 are injection molded with polyvinyl chloride insulating rubber. Polyvinyl chloride has excellent insulation properties and can effectively isolate current, prevent current leakage or leakage, and improve safety in use. One end of the male connector 1 is open and recessed inward to form a receiving cavity 3, which is cylindrical; a number of cores 4 parallel to each other are fixedly connected to the male connector 1. As shown in the figure, the number of cores 4 in this embodiment is five, and each core 4 is located in the receiving cavity 3 and extends along the depth direction of the receiving cavity 3. In this embodiment, the core 4 is made of copper-plated nickel material. The copper-plated nickel material has strong corrosion resistance on the surface, and also has the characteristics of good contact and conductivity. The female plug connector 2 is integrally connected with an insert block 5, which is inserted into the accommodating cavity 3; the insert block 5 is provided with a plurality of mounting holes at one end facing the accommodating cavity 3, and the number of mounting holes is equal to the number of core bodies 4, and a core sleeve 6 is fixedly connected in each mounting hole, and each core body 4 is respectively inserted into each core sleeve 6. Among them, the end face of the core sleeve 6 is lower than the end face of the insert block 5, and such a design can reduce the possibility of water and dust contacting the core sleeve 6, and improve the waterproof and dustproof performance of the connecting plug.
[0038] When connecting, an external force is applied to the plug block 5 and the plug block 5 is inserted into the accommodating cavity 3, and the detachable connection between the male connector 1 and the female connector 2 is achieved by the action of friction. At the same time, each core body 4 is respectively inserted into each core sleeve 6, and the core body 4 serves as a metal terminal to achieve electrical connection. By adopting the male-female plug-in design, there is no need to use a sealing ring; at the same time, by the sinking design of the core body 4, each core body 4 forms a certain height difference with the opening at the end of the male connector 1. This design simplifies the structure of the traditional connection plug, reduces the manufacturing cost, and ensures waterproof and dustproof performance.
[0039] Combination Figure 3 Specifically, the male connector 1 is also integrally connected with a limit block 7, and the cross-section of the limit block 7 is crescent-shaped. The limit block 7 is located in the accommodating cavity 3 and is extended along the length direction of the core 4. The length of the limit block 7 is lower than the cavity depth of the accommodating cavity 3, so that the end face of the limit block 7 and the end face of the male connector 1 form a step shape. The length of the limit block 7 is greater than the length of the core 4, so that a height difference is formed between the limit block 7 and the core 4. The existence of the height difference can reduce the possibility of dust and moisture contacting the core 4. A stop block 10 is integrally formed on the outer surface of the plug 5. The shape of the stop block 10 is the same as that of the limit block 7. When the female connector 2 is plugged into the male connector 1, the stop block 10 abuts against the limit block 7.
[0040] When the plug block 5 is inserted into the accommodating cavity 3, the presence of the limit block 7 can limit the circumferential rotation of the plug block 5, thereby improving the connection stability of the male connector 1 and the female connector 2. At the same time, the stop block 10 will abut against the limit block 7 to shield the limit block 7, thereby further reducing the possibility of dust and water contacting the core 4.
[0041] Reference Figure 1 In addition, a plurality of anti-slip strips 8 are fixedly connected to the outer surface of the plug block 5, and the anti-slip strips 8 are spaced apart along the insertion direction of the plug block 5. The anti-slip strips 8 can increase the roughness of the outer surface of the plug block 5, increase the friction between the female connector 2 and the male connector 1, and further improve the connection stability after the two are plugged in. In some embodiments, convex strips 9 are fixedly connected to the outer surfaces of the male connector 1 and the female connector 2, and the convex strips 9 are extended along the plugging direction of the male connector 1 and the female connector 2. The presence of the convex strips 9 can increase the roughness of the surface of the male connector 1 and the female connector 2, making it convenient for the user to hold and apply force, thereby realizing the plugging and unplugging of the male connector 1 and the female connector 2.
[0042] The implementation principle of a connection plug in the embodiment of the present application is as follows: during installation, the plug block 5 is inserted into the accommodating cavity 3, and the detachable connection between the male connector 1 and the female connector 2 is achieved by the action of friction; at the same time, each core body 4 is respectively inserted into each core sleeve 6, and the core body 4 serves as a metal terminal to achieve electrical connection. By adopting a male-female plug-in design, there is no need to use a sealing ring; at the same time, by designing the core body 4 to sink, each core body 4 forms a certain height difference with the opening at the end of the male connector 1. This design simplifies the structure of the traditional connection plug, reduces the manufacturing cost, and ensures waterproof and dustproof performance.
[0043] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
