Referring to fig. 7 to 8, in consideration of the corresponding installation relationship between the locking seats 200 and the installation seats 110, the number of the at least one locking seat 200 may be equal to the number of the installation seats 110, the locking seats 200 are installed on the installation seats 110 and can rotate around the locking cam 111, the locking seat 200 in this embodiment is provided with three insertion holes 201 (at least two insertion holes) into which a plug can be inserted, and the insertion holes 201 are respectively and correspondingly provided with a first electrical connector 210, a second electrical connector 220 and a third electrical connector 230; the first electrical connector 210 is electrically connected with a first electrical conductor 211, the second electrical connector 220 is electrically connected with a second electrical conductor 221, the third electrical connector 230 is electrically connected with a third electrical conductor 231, and the first electrical conductor 211, the second electrical conductor 221 and the third electrical conductor 231 all extend out and are correspondingly clamped into the first electrical conductor groove 1121, the second electrical conductor groove 1131 and the third electrical conductor groove 1141 respectively and can move in the corresponding electrical conductor grooves in the process of rotating the locking seat 200.

After the corresponding installation of the locking seat 200 and the installation seat 110 is completed, all the electric conductors on the same locking seat 200 are in contact with the electric conduction grooves in the insulation rail groove where the electric conductors are located in the rotation process of the locking seat 200, and the locking cam 111 squeezes and locks the blades of the plug and the electric connector when the locking seat 200 rotates to the set position, and releases the locking of the blades of the plug and the electric connector when the locking seat 200 rotates away from the set position.

It should be noted that the above-mentioned set position, i.e. the design position where the locking cam 111 tightly presses and locks the insert and the electric connector, should at least ensure that the electric conductor on the locking seat 200 is simultaneously contacted with the electric conduction groove in the insulated rail groove where it is located.

When a plug is required to be inserted, the locking seat 200 can be rotated to the unlocking position, the plug can be smoothly inserted into the jack 201 at the moment, after the plug is inserted into the jack 201, the locking seat 200 is rotated to the set position, and the locking cam 111 tightly presses and locks the plug-in sheet and the electric connection body.

Referring to fig. 9, the manner of the locking cam 111 to tightly lock the blade and the electric connector in the present invention is not limited, and may be any suitable structure capable of tightly locking the blade and the electric connector by the locking cam 111. In this embodiment, the first electrical connector 210 is provided with two elastic claw pieces, the second electrical connector 220 and the third electrical connector 230 are provided with a first elastic claw piece 222, a second elastic claw piece 223 and a third elastic claw piece 224, and the locking cam 111 is disposed between the second electrical connector 220 and the third electrical connector 230. If the locking cam 111 is a conductor, an insulation isolation structure should be additionally provided to insulate and isolate the locking cam 111 from the elastic claw pieces on the electrical connectors on both sides. If the locking cam 111 is made of an insulating material, the third elastic claw pieces 224 of the second and third electrical connectors 220 and 230 on both sides can be directly pushed to deform so as to squeeze the insertion piece inserted from the insertion hole 201, thereby achieving locking.

Referring to fig. 8, in an embodiment of the present invention, a first pushing body 240 is linearly movably installed on the locking seat 200 on one side of the locking cam 111, a second pushing body 250 is linearly movably installed on the locking seat 200 on the other side of the locking cam 111, two sides of the locking cam 111 simultaneously push the first pushing body 240 and the second pushing body 250 to move so as to squeeze and lock the third elastic claw pieces 224 on two sides with the insertion piece, and the pushing bodies on two sides are installed with a restoring body and are restored by the action of the restoring body.

Referring to fig. 10, the cross-sectional shape of the cam according to the present invention may be any suitable shape, such as a rectangle with rounded corners, or an irregular shape, and as an example of the present invention, the cross-section of the cam according to the present invention is an ellipse, when the unlocking is released, the locking cam 111 is mounted on the base plate 100 and is stationary, the locking seat 200 rotates around the center of the ellipse, and when both sides of the minor axis of the ellipse are in contact with the pushing body, the spring pulls the pushing body to move toward the locking cam 111 to release the inserting piece and the elastic claw piece, thereby releasing the inserting piece. When the locking seat needs to be squeezed and locked, the locking seat 200 rotates 90 degrees around the center of the ellipse, the pushing bodies on two sides of the long axis of the ellipse move to the side away from the locking cam 111 (i.e. to the side facing the third elastic claw piece 224), and the convex bodies on the pushing bodies abut against the inserting pieces while the third elastic claw piece 224 is pushed to deform and squeeze the inserting pieces. However, in all other embodiments of the present invention, the locking may also be achieved for a rotation of 15 °, 30 °, 45 °, etc.

In the present invention, the number of the insulated rail slots matches the number of the insertion holes 201, and if the two-hole socket is not grounded, the number of the insulated rail slots is two. However, in another embodiment of the present invention, three insertion holes 201 are formed in the locking base 200, and the mounting base 110 includes three insulating rail grooves, and the conductive grooves in the three insulating rail grooves are electrically connected to the live wire, the neutral wire and the ground wire, respectively.

This structure makes the back surface of the substrate 100 more flat for easy mounting and better protects the wires.

Referring to fig. 5, in order to prevent dust from entering, in an example of the present invention, an annular rib 115 is disposed around the mounting seat 110 and centered around the center of the locking cam 111, an annular boss (not shown) is disposed on the locking seat 200 and is matched with the rib 115, and a gap seal is formed between the annular rib 115 and the annular boss.

correspondingly electrically connecting and clamping the electric conductors of the locking seat 200 into the corresponding electric conduction grooves, and extending the locking cam 111 to between at least two electric connection bodies;

when the locking seat 200 is rotated to enable the electric conductor to move along the corresponding conductive groove, and the locking seat is rotated to a set position, the convex part of the locking cam 111 tightly squeezes and locks the plug insert and the electric connector, and when the locking seat rotates to be far away from the set position, the locking cam 111 unlocks and releases the plug insert and the electric connector. The method of the invention not only can set a loose matching mode between the inserting sheet and the jack 201, but also can tightly lock the inserting sheet and the electric contact body through the locking cam 111 when reaching the set position.

In conclusion, the socket and the method can not only set a loose matching mode, but also tightly press and lock the inserting sheet and the electric contact body through the locking cam when reaching the set position, are practical and safe, and have great market prospect.
