Detailed ways

Below in conjunction with accompanying drawing, the utility model is further elaborated:

[Example 1]

As shown in FIG. 1 , the socket includes: a housing 1 , an interface unit 2 and a shielding mechanism 3 . The interface unit 2 is located inside the housing 1 , and the shielding mechanism 3 can selectively shield the interface unit 2 .

The casing 1 is a hollow body. The casing 1 has a communication port 10 located at one end of the casing 1 . The communication port 10 connects the inside and the outside of the casing 1 . The interface unit 2 has a socket 20 , and the socket 20 of the interface unit 2 is opposite to the communication port 10 of the housing 1 . When using the socket, the user only needs to insert the electrodes of the plug into the socket 20 of the interface unit 2 through the communication port 10 .

The interface unit 2 includes, but is not limited to, a power interface, a USB interface, a network cable interface, a telephone line interface, and the like.

As shown in FIG. 2 , the shielding mechanism 3 includes: a foldable plate 31 , a transmission part 32 and a guide part 33 . The foldable plate 31 passes through the transmission part 32 and the guide part 33 in turn and is attached to the transmission part 32 and the guide part 33. The upper end of the transmission part 32 and the lower end of the communication port 10 pass through the same plane S, and the plane S and the communication port 10 The extending direction is parallel, that is, the plane where the lower end of the communication port 10 is located is tangent to the upper end of the transmission part 32 , and the foldable plate 31 extends from the communication port 10 toward the other end of the housing 1 . The communication port 10 can be closed or opened by the foldable plate 31 moving around the conveying part 32 and the guiding part 33 . Specifically, the guide member 33 is located inside the casing 1 and farther away from the communication port 10 than the interface unit 2 . The guide part 33 guides the moving track of the foldable board 31 so that the foldable board 31 avoids the interface unit 2 and prevents the foldable board 31 from being blocked from moving.

In this embodiment, both the conveying part 32 and the guiding part 33 are gears, and one surface of the foldable plate 31 has saw teeth, and the foldable plate 31 meshes with the conveying part 32 and the guiding part 33 at the same time. This joint method is relatively stable and not easy to slip. Certainly, in other embodiments, the transmission part 32 and the guide part 33 may also be pulleys, which promote the movement of the foldable plate 31 through friction.

In other modified examples, the transmission part 32 and the guide part 33 may also be protrusions, which only play a role of guiding the foldable plate 31 .

In this embodiment, the housing 1 includes: a base 11 and two end covers 12 . Both ends of the base 11 have openings respectively, and two end caps 12 respectively seal the openings at both ends of the base 11 . Since both ends of the base 11 have openings, it is convenient to install the components of the interface unit 2 and the shielding mechanism 3 from two directions. Furthermore, since the bottom surface is closed, it is possible to prevent the components from falling to the ground and even causing damage.

In this embodiment, there are multiple interface units 2, and the multiple interface units 2 are arranged in a row. The extending direction of the conveying part 32 is perpendicular to the arrangement direction of the plurality of interface units 2 , that is, the moving direction of the foldable plate 31 is the same as the arrangement direction of the plurality of interface units 2 . As shown in Figures 2-4, when multiple interface units 2 need to be used, the foldable plate 31 does not block all interface units 2, and the socket is in the first state at this time; when some interface units 2 need to be used, The foldable plate 31 blocks the unused interface units 2, and now the socket is in the second state; when there is no interface unit 2 to be used, the foldable plate 31 blocks all the interface units 2 and seals the communication port 10, At this moment, the socket is in the third state. The above arrangement can not only protect the interface unit 2 from dust or water entering the interface unit 2, but also protect the interface unit 2 that is not in use when some interface units 2 are in use, so as to improve the flexibility of use of the socket.

As a modified example of this embodiment, a plurality of interface units 2 may also be arranged in multiple rows, and the extending direction of the transmission member 32 is the same as or perpendicular to the arrangement direction of each row of interface units 2 .

Certainly, in other embodiments, the extending direction of the transmission member 32 may also form an included angle other than 90° with the arrangement direction of the plurality of interface units 2 . In the case where a plurality of interface units 2 are arranged in a row, the extending direction of the transmission member 32 may also be the same as the arrangement direction of the interface units 2 .

The foldable plate 31 in the present invention can be a flexible plate, or a chain-like (discontinuous) hard plate, as long as it is a structure that can realize bending and folding of the plate.

As a preferred solution, the foldable panel 31 is formed of flexible resin material. Compared with metal materials, the resin material has a lower density, which can prevent the socket itself from being too heavy; the cost of the resin material is lower; and the resin material has better sealing performance. In this embodiment, the foldable panel 31 is formed of plastic.

As a preferred solution, the transmission part 32 is driven by a motor. This driving method can realize the automatic movement of the foldable plate 31, making the protection function of the socket more convenient.

The socket with the above-mentioned structure can not only realize waterproof and dustproof protection functions, but also prevent water or dust from hiding in the connecting port, avoid potential safety hazards, and prevent the socket from being too large, which is beneficial to miniaturization.

[Example 2]

In this embodiment, the conveying member 32 is also driven by a motor. As shown in FIG. 5 , different from the first embodiment, the socket further includes: a photoelectric sensor 4 , which is located near the communication port 10 and detects whether there is an object at the communication port 10 . As shown in Figure 6, the photoelectric sensor 4 is connected in series with the motor through a voltage relay. When the photoelectric sensor 4 detects that there is an object at the detection communication port 10, the voltage relay is disconnected, and the motor stops rotating, thereby stopping the movement of the foldable plate 31. . On the one hand, it can prevent the foldable plate 31 from abutting against the plug when the plug is not pulled out, causing damage to the shielding mechanism 3 due to the bias force; Injury.

[Embodiment three]

In this embodiment, the conveying member 32 is also driven by a motor. As shown in Figure 6, the difference from the first embodiment is that the motor is connected in series with an overload protector. When there is an object at the connection port 10, the rotation of the motor is blocked. At this time, because the electric energy cannot be converted into mechanical energy, the voltage at both ends of the motor changes suddenly, that is, the voltage suddenly increases sharply, and the voltage at both ends of the protective resistor connected in parallel with the motor also increases at the same time. Large, resulting in an increase in current, the overload protector in series with it detects the increase in current in the circuit, automatically disconnects, and stops the motor from rotating. Similar to the second embodiment, the solution of this embodiment can also play the role of protecting the shielding mechanism 3 and protecting human hands.

The above-described embodiments are only preferred examples of the utility model, and are not intended to limit the scope of implementation of the utility model, so all equivalent changes or modifications made according to the structure, features and principles described in the utility model patent scope , should be included in the utility model patent application scope.
