When the tripod plug is inserted, its end can act on the second shield 423 and move the second shield 423 towards the first shield 422, while the guide rods 424 also move in the guide channels 425.

A force receiving slope 426 is provided on each of the first and second shield portions 4221 and 4231, so that the pins act on the force receiving slope 426 to move the shield assembly 420. Specifically, for the first shielding portion 4221, the force-bearing inclined plane 426 inclines from top to bottom in a direction away from the second protection body 423, and at this time, when the two-pin plug is inserted, the two-pin plug can generate a component force towards the second protection body 423 on the first protection body 422, so that the first protection body 422 moves towards the second protection body 423. For the second shielding portion 4231, since it needs to be matched with a three-pin plug, the force-receiving inclined plane 426 on the second shielding portion 4231 needs to have the structural characteristics of the force-receiving inclined plane 426 of the first shielding portion 4221, and also needs to be matched with the three-pin plug in an inclined state, so that the force-receiving inclined plane 426 on the second shielding portion 4231 is set to be in an inclined state forming a certain angle with the groove 412.

In addition, a restoring elastic member 427 may be further disposed between the first protection body 422 and the second protection body 423, and the restoring elastic member 427 is disposed between the first protection body 422 and the second protection body 423 for providing restoring power to the first protection body 422 and the second protection body 423.

Thus, the first shield 422 and the second shield 423 can spontaneously return to the open position by the elastic restoring member 427 when the plug 1000 leaves the socket, thereby continuing to protect the socket.

In some embodiments, the elastic restoring member 427 may be a spring, and when installed, one end of the spring is sleeved on the outer circumference of the guide rod 424, the other end of the spring is inserted into the guide channel 425, and the other end of the spring is limited by the guide channel 425 (for example, the guide channel 425 may be designed to have a shape similar to a stepped hole), so that an elastic effect is formed between the first protection body 422 and the second protection body 423.

Further, in order to improve the stability of the first protection body 422 and the second protection body 423 in the open position, the end portions of the first protection body 422 and the second protection body 423 are respectively provided with a limiting protrusion 428, the two ends of the base 410 in the length direction are provided with limiting grooves 413, the limiting protrusions 428 and the limiting grooves 413 can be buckled with each other, and the first protection body 422 and the second protection body 423 can be driven to be buckled at the two ends of the base 410 respectively by combining the elastic action of the resetting elastic member 427.

On the basis of the operation of one of the first guard 422 and the second guard 423, the distance between the two pairs of pin guiding holes 411 is increased, so that the upper cover 100 can simultaneously accommodate two plugs 1000, thereby realizing the simultaneous operation of the first guard 422 and the second guard 423.

In addition, the two pairs of pin guiding holes 411 may be configured differently, but may also be configured identically, for example, two pairs of two-pin insertion holes, and only the corresponding stress inclined plane 426 of the protection body needs to be adapted.

In another embodiment, the pin guiding holes 411 may be a pair, such as the aforesaid two-pin socket or three-pin socket, the base 410 has a guiding channel 425, the protective assembly 420 includes a protective body, such as the aforesaid first protective body 422 or second protective body 423, the protective body is movably disposed on the base 410 and at least partially located on the insertion path of the pin, the protective body has at least an open position and a conducting position on the moving path, a guide rod 424 is convexly disposed on one side of the protective body, the guide rod 424 can move in the guiding channel 425, the guide rod 424 cooperates with the guiding channel 425 to form another of at least two guiding mechanisms, when the protective body is located at the open position, the pin guiding holes 411 are separated by the protective body, and when the protective body is located at the conducting position, the pin guiding holes communicate with the pin guiding holes 411.

Thus, by changing the location of the guide channel 425, the receptacle can be changed to a single-head receptacle for only a single plug to be inserted, which has similar properties to the receptacle described above, and other components such as the restoring spring 427 can be applied to the single-head receptacle, for example, the restoring spring 427 can be disposed between the shield and the base 410 for providing restoring power to the shield.

Of course, in other embodiments, more pairs of jacks can be provided on the socket, more pairs of pin guide holes 411 can be provided on the base 410, and more shields can be provided on the base 410 to enable the socket to accommodate the use of more plugs 1000.

On the other hand, in order to avoid the situation that the insertion of a component other than the plug 1000 into the socket also causes the protection component 420 to move to close the socket circuit, please refer to fig. 1, fig. 3 and fig. 7-8 in combination, in some embodiments, a stop block 414 is protrudingly disposed on the base 410, the stop block 414 is located on the moving path of the protection component 420, and both sides (in the width direction of the base 410) of the bottom of the protection component 420 (such as the aforementioned first protection body 422 and/or the second protection body 423) are tilted upward to form an escape distance with the base 410, which is greater than the height of the stop block 414.

In this manner, when plug 1000 is inserted, the pins of plug 1000 can act equally on both sides of the bottom of shield assembly 420, so that shield assembly 420 can pass over stop block 414, but when other components are inserted, the other components generally act on only one side of shield assembly 420, so that the side of shield assembly 420 is pressed downward, and stop block 414 can prevent shield assembly 420 from moving, thereby improving the safety of the socket in use to some extent.

Finally, it should be noted that the socket and the safety door structure in the embodiment of the present invention may also be deformed in various structures, for example, referring to fig. 9, in some embodiments, a plurality of safety door structures are arranged in a length direction to form a new safety door structure, and correspondingly, the socket corresponds to a housing designed to be able to mount the new safety door structure, and through the deformation design, the socket and the safety door structure may be suitable for use of a plurality of plugs.
