Description of reference numerals: the socket comprises a socket shell 1, a power line 11, a plug board 2, a female slot 21, a contact piece 211, a conductive spring 212, a metal contact 22, a sliding piece 3, an electrical contact 31, a first protrusion 41, a second protrusion 42, a connecting spring 43, a main protrusion 44, a main groove 45, a return spring 46, a guide slot 51 and a limiting protrusion 52.

Detailed Description

The invention is explained in detail below with reference to the accompanying drawings:

as shown in fig. 1-4: a waterproof socket includes

The plug board and the socket shell are matched and connected in a framework oil seal mode, so that the plug board can rotate while sealing between the plug board and the socket shell is ensured.

According to the difference of the linkage structure, the following two embodiments can be extended:

example 1

As shown in fig. 1 and 2: the linkage mechanism comprises

A plurality of first protrusions 41 arranged on the proximal end surface of the sliding sheet 3;

second protrusions 42, corresponding to the first protrusions 41 in position and number, disposed on the distal end surface of the bottom of the socket housing 1;

the connecting spring 43 is arranged between the inserting plate 2 and the sliding sheet 3 and is connected with the inserting plate 2 and the sliding sheet 3;

the rotating plugboard 2 drives the sliding sheet 3 to rotate through the connecting spring 43, the sliding sheet 3 rotates until the first protrusion 41 is contacted with the second protrusion 42, and the sliding sheet 3 moves towards the plugboard 2, so that the electric contact 31 is contacted with the metal contact 22 to realize electrification.

Here, the distance or approach of the sliding sheet 3 from or to the board 2 is realized by the misalignment or contact of the first projection 41 and the second projection 42, and the motive force for the movement of the sliding sheet 3 comes from the positional relationship between the first projection 41 and the second projection 42 and the connecting spring 43.

Example 2

As shown in fig. 3 and 4: the linkage mechanism comprises

A plurality of main bulges 44 are arranged on the near end surface of the inserting plate 2;

main grooves 45 corresponding to the positions and the number of the first protrusions 41 and arranged on the distal end surface of the sliding sheet 3;

a return spring 46 arranged between the sliding sheet 3 and the bottom of the socket housing 1;

the rotating insert plate 2 makes the main protrusion 44 fall into the main groove 45, the sliding sheet 3 moves towards the insert plate 2 under the action of the return spring 46, and the electric contact 31 is contacted with the metal contact 22 to realize electrification.

The shifting of the sliding sheet 3 away from or close to the inserting plate 2 is realized by the dislocation and overlapping of the main protrusion 44 and the main groove 45, and the power of the shifting of the sliding sheet 3 comes from the positional relationship between the first protrusion 41 and the second protrusion 42 and the connecting spring 43.

On the basis of the examples 1 and 2:

as shown in fig. 5: the inner side wall surface of the socket housing 1 is provided with a guide groove 51 for rotation limitation, and the plug is provided with a limit projection 52 matched with the guide groove. The guide groove comprises a vertical groove and a horizontal groove, the limiting protrusion falls into the horizontal groove through the vertical groove, and then the limiting protrusion moves in the horizontal groove when the plug is rotated. The plug board 2 rotates synchronously while the plug is rotated, and finally, the metal contact 22 and the electric contact 31 in the plug board 2 are electrified in a contact mode. The socket housing and the plug can be prevented from being separated by the design of the guide groove. It should be noted that the width of the horizontal groove decreases from one end of the connecting vertical groove to the other end.

Certainly, if the plug and the socket shell are in interference fit, the arrangement of the guide groove is not considered, but the use difficulty of a user is increased (particularly, the difficulty of rotating and plugging the plug by the user is increased).

At least one of the distal end face of the board 2 or the end face of the plug is provided with a sealing gasket. This prevents the female slots 21 of the board 2 from being completely isolated from each other at the moment of contact between the board 2 and the plug.

A distance adjusting mechanism is arranged in the female slot 21, and the distance adjusting mechanism comprises a contact piece 211 sliding in the female slot 21 and a conductive spring 212 connecting the metal contact 22 and the contact piece 211. Because the male plugs of different plugs are different in length, the defect that the metal contact 22 cannot be contacted due to the fact that the plug is too short can be compensated through the distance adjusting mechanism; the longer male plug may be compensated for by the compression of the conductive spring 212.

The working principle is as follows:

before use, a certain distance is kept between the inserting plate 2 and the sliding sheet 3 to ensure that the inserting plate is completely uncharged;

after the plug is completely inserted into the plugboard, the plug is contacted with the metal contact 22, and the female slots 21 in the plugboard 2 are completely isolated from the outside, so that even if moisture exists in each female slot, electric leakage cannot be caused;

the plug board is driven to rotate by rotating the plug, and when the plug board rotates to a specific position, the electric contact 31 is ensured to be in contact with the metal contact 22 and electrified under the action of the linkage mechanism.

While the present invention has been shown and described with reference to particular embodiments and alternatives thereof, it will be understood that various changes and modifications can be made without departing from the spirit and scope of the invention. It is understood, therefore, that the invention is not to be limited, except as by the appended claims and their equivalents.
