Description
Technical Field
[0001] This utility model relates to the field of power equipment technology, specifically to a dust cover device for connectors and a connector. Background Technology
[0002] Connectors, also known as plugs, are commonly used components in electronic and electrical equipment. Connectors typically consist of a male connector and a female connector. After the male and female connectors are plugged in, they can transmit signals or current. The mechanical and electrical properties of connectors directly affect the performance of electronic and electrical equipment. In current technology, female connectors are generally exposed, with the connection holes for the male connector directly exposed to the outside environment. When not in use, this makes them susceptible to the entry of dust and other impurities, thus affecting their functionality. Utility Model Content

[0033] Example 1
[0034] like Figure 1-5 As shown, a dust cover device for a connector includes:
[0035] The female body 1 includes a mounting side having a first mounting base 1-1 and a second mounting base 1-2, and a first connecting hole 1-3 on the surface that is connected to the male pin.
[0036] The dust cover body 2 includes a first dust cover 2-1 rotatably fitted on a first mounting base 1-1 and a second dust cover 2-2 rotatably fitted on a second mounting base 1-2. The first dust cover 2-1 and the second dust cover 2-2 are combined to form a rectangular structure, and both the first dust cover 2-1 and the second dust cover 2-2 can rotate independently.
[0037] The two second dust covers 2-2 are located on both sides of the first mounting base 1-1;
[0038] like Figure 1-3 As shown, the dust cover device is in its first and second states.
[0039] In the first state, the first dust cover 2-1 covers the surface of the female connector body 1 and cooperates with the second dust cover 2-2 to seal the first connection hole 1-3, that is, the first state is the state in which the female connector body 1 is not used; in the second state, the first dust cover 2-1 rotates around the first mounting base 1-1 so that the first connection hole 1-3 is exposed to the outside. At this time, the male connector can be installed on the female connector body 1 to draw power, that is, the second state is the state in which the female connector body 1 is used.
[0040] The first mounting base 1-1 and the second mounting base 1-2 are both provided with rotating holes. The first dust cover 2-1 and the second dust cover 2-2 are rotatably fitted onto the rotating holes via rotating shafts, which facilitates the opening and closing of the first dust cover 2-1 and the second dust cover 2-2 onto the female body 1.
[0041] like Figure 2 As shown, the first dust cover 2-1 is provided with a first hinge seat 2-1-1, which is rotatably engaged with the first mounting seat 1-1; the second dust cover 2-2 is provided with a second hinge seat 2-2-1, which is rotatably engaged with the second mounting seat 1-2.
[0042] like Figure 1-3 As shown, the first dust cover 2-1 has a convex-shaped structure, with a first cover portion 2-1-2 and a first extension portion 2-1-3 located at the front end of the first cover portion 2-1-2; the second dust cover 2-2 has an L-shaped structure, with a second cover portion 2-2-2 and a second extension portion 2-2-3 located at the front end of the second cover portion 2-2-2; the second cover portion 2-2-2 is provided with a plurality of first limiting holes 2-2-4, which cooperate with the first limiting protrusion 3-3 of the male head 3 to limit the male head 3.
[0043] like Figure 4 As shown, the surface of the female body 1 is provided with an annular limiting groove 1-4, and the first connecting hole 1-3 is located in the area enclosed by the annular limiting groove 1-4. The annular limiting groove 1-4 cooperates with the annular enclosure 3-2 of the male head 3 to prevent the operator's hand from directly contacting the pin inside the annular enclosure 3-2 when drawing power.
[0044] The annular limiting groove 1-4 is provided with a second limiting hole 1-5, which cooperates with the second limiting protrusion 3-4 of the male head 3 to limit the male head 3.
[0045] The surface of the female body 1 is provided with a second connecting hole 1-6 for connecting with the box 4, and the lower surface of the second dust cover 2-2 is provided with a matching covering protrusion 2-3, which can protect the connection structure between the female body 1 and the box 4, and also limit the position between the second dust cover 2-2 and the female body 1.
[0046] like Figure 5-10 As shown, a connector includes a dust cover device, a male connector 3, and a housing 4;
[0047] The male head 3 is equipped with a pin 3-1 and an annular retaining 3-2 that matches the annular limiting groove 1-4;
[0048] The male head 3 is also provided with a first limiting protrusion 3-3 that matches the first limiting hole 2-2-4 and a second limiting protrusion 3-4 that matches the second limiting hole 1-5;
[0049] The box 4 is provided with a connecting part 4-1 that matches the second connecting hole 1-6;
[0050] In the second state, the male head 3 is installed on the female body 1 and located between the two second dust covers 2-2. The two second dust covers 2-2 cover the female body 1, the covering protrusion 2-3 is embedded in the second connecting hole 1-6, and the first dust cover 2-1 is in the open state, thus removing the cover from the first connecting hole 1-3.
[0051] The above are merely preferred embodiments of this utility model. The scope of protection of this utility model is defined by the scope of the claims. Any improvements and modifications made by those skilled in the art without departing from the spirit and scope of this utility model should also be considered as protection within the scope of this utility model.
