The present invention provides a socket 100, which aims to solve the problem that dust is easily accumulated between a jack 13 and a driving surface 311.

The following will describe the specific structure of the socket 100 of the present invention, and will describe the socket 100 as a horizontal example:

referring to fig. 1 to 3 and 5 to 7, in an embodiment of the socket 100 of the present invention, the socket 100 includes a front cover 10, a rear core 20 and a protection door 30; the face cover 10 is provided with two insertion holes 13; the face cover 10 covers the rear core 20 and surrounds the rear core 20 to form a mounting cavity, and the jack 13 is communicated with the mounting cavity; the protective door 30 is arranged in the mounting cavity in a reversible manner and has a first state and a second state, and the protective door 30 is provided with a driving surface 311;

when the protective door 30 is in the first state, the driving surface 311 abuts against the surface of the face cover 10 facing the installation cavity and blocks the insertion hole 13, and the driving surface 311 is flush with the end surface of the insertion hole 13 close to the rear core 20; when the protective door 30 is in the second state, the driving surface 311 and the insertion hole 13 are arranged at an interval, the insertion hole 13 is opened, and the driving surface 311 and the end surface of the insertion hole 13 close to the rear core 20 form an included angle.

It can be understood that, in the socket 100 of the present invention, when the plug 200 passes through the insertion hole 13 and contacts with the driving surface 311 of the protective door 30, the plug 200 will exert a pushing force on the driving surface 311 to turn the protective door 30 over, so that the protective door 30 moves from the first state to the second state, at this time, the driving surface 311 will be spaced from the insertion hole 13 and open the insertion hole 13, so that the plug 200 is inserted into the sleeve 24 of the rear core 20; when the plug 200 is pulled out from the mounting cavity, the plug 200 releases the pushing force on the driving surface 311 to move the protective door 30 from the second state to the first state, at this time, the driving surface 311 abuts against the surface of the face cover 10 facing the mounting cavity and blocks the jack 13, and the driving surface 311 is flush with the end surface of the jack 13 close to the rear core 20, that is, the driving surface 311 can cover the whole area of the jack 13, so that an inner concave space is avoided between the driving surface 311 and the jack 13, thereby preventing dust from accumulating in the inner concave space, that is, preventing dust from accumulating between the jack 13 and the driving surface 311. In addition, when the protection door 30 is in the first state, the driving surface 311 of the protection door 30 is displayed as a flat surface from the appearance, so that children are not easily attracted to use articles or fingers to try, and potential safety hazards are reduced.

It should be noted that two plug bushes 24 are arranged in the mounting cavity, each plug bush 24 is arranged opposite to one jack 13, when two pins of the plug 200 respectively pass through the two jacks 13 and move from the first state to the second state, each pin of the plug 200 is inserted into one plug bush 24 to be electrically connected with the plug bush 24, and the plug 200 is electrically connected with the commercial power through the socket 100.

In practical application, during the turning process of the protective door 30, the switching between the first state and the second state can be directly realized by adopting one-time turning, for example, a torsion spring is arranged between the protective door 30 and the face cover 10, when the plug 200 passes through the jack 13 and contacts with the driving surface 311 on the protective door 30, the plug 200 applies a pushing force on the driving surface 311, and the protective door 30 presses the torsion spring to deform the torsion spring, so that the protective door 30 can be turned from the first state to the second state; when the plug 200 is pulled out from the mounting cavity, the plug 200 releases the pushing force on the driving surface 311, and the torsion spring generates a resilience force and acts on the protection door 30, so that the protection door 30 can be turned from the second state to the first state.

Alternatively, referring to fig. 3 and fig. 7 in combination, in an embodiment of the socket 100 of the present invention, a slide rail 21 is disposed in the installation cavity, the slide rail 21 extends in a direction parallel to the face cover 10, the slide rail 21 is disposed opposite to the face cover 10, and the protection door 30 is located between the slide rail 21 and the face cover 10; when the plug 200 abuts against the driving surface 311 and pushes the protection door 30 to contact with the slide rail 21, the protection door 30 is turned over and slides along the extending direction of the slide rail 21, so that the protection door 30 moves from the first state to the second state.

During the turning process, the protection door 30 may first rotate in a turning manner, and then move, so that the protection door 30 is switched between the first state and the second state, for example, when the sliding rail 21 is disposed in the installation cavity, and the protection door 30 is disposed between the sliding rail 21 and the face cover 10, when the plug 200 passes through the insertion hole 13 and contacts with the driving surface 311 on the protection door 30, the plug 200 will apply a pushing force on the driving surface 311, so that one vertex position of the protection door 30 contacts with the sliding rail 21, at this time, the plug 200 continues to apply the pushing force, the protection door 30 will turn over relative to the sliding rail 21 with the vertex position as an axis, and when the plane with the vertex position of the protection door 30 is turned over to contact with the sliding rail 21, the protection door 30 will slide along the extending direction of the sliding rail 21, so that the protection door 30 can move from the first state to the second state; when the plug 200 is pulled out from the mounting cavity, the plug 200 releases the pushing force on the driving surface 311, and at this time, the protection door 30 firstly slides along the extending direction of the slide rail 21, and then turns over until the driving surface 311 is flush with the end surface of the jack 13 close to the rear core 20 and covers the whole area of the jack 13, so that the protection door 30 can move from the second state to the first state. This ensures the stability of the protective door 30 during the movement to smoothly switch between the first state and the second state.

Referring to fig. 4, 8 and 11, in an embodiment of the socket 100 of the present invention, the protection door 30 includes a driving portion 31 and a guiding portion 32; the driving portion 31 has the driving surface 311; the guide portion 32 is connected to one side of the driving portion 31, which is far away from the face cover 10, and has a guide surface 321, the guide surface 321 and the driving surface 311 form an included angle, the guide surface 321 is provided with a sliding groove 3211, when the plug 200 abuts against the driving surface 311 and pushes the protection door 30 to contact with the sliding rail 21, the protection door 30 is turned over, and the sliding groove 3211 is in sliding fit with the sliding rail 21, so that the protection door 30 slides along the extending direction of the sliding rail 21.

It can be understood that, when the protection door 30 is in the first state, the driving surface 311 abuts against the surface of the face cover 10 facing the rear core 20 and is flush with the end surface of the insertion hole 13 close to the rear core 20, at this time, the guide surface 321 and the surface of the guide rail facing the face cover 10 are arranged at an included angle, so that an escape space is provided between the guide surface 321 and the guide rail, when the plug 200 abuts against the driving surface 311 and pushes the protection door 30 to contact with the slide rail 21, the protection door 30 is turned over in the escape space, so that the protection door 30 is turned over to be flush with the guide surface 321 and the surface of the guide rail facing the face cover 10, so that the slide groove 3211 is in sliding fit with the slide rail 21, the plug 200 continues to apply a pushing force to the driving surface 311, so as to drive the protection door 30 to slide to the second state along the extending direction of the slide rail 21, thereby ensuring the stability of the protection door 30 during the turning and sliding, and avoiding the position offset of the protection door 30 during the switching between the first state and the second state, thereby affecting the use effect.

Specifically, the driving portion 31 and the guiding portion 32 of the protection door 30 are of an integral structure, and the extending direction of the protection door 30 is perpendicular to the arrangement direction of the two insertion holes 13, so that when the protection door 30 is in the first state, the driving surface 311 of the driving portion 31 simultaneously blocks the two insertion holes 13.

Referring to fig. 4 and fig. 8 in combination, in an embodiment of the socket 100 of the present invention, the guiding portion 32 further has a limiting surface 322, the limiting surface 322 is located between the guiding surface 321 and the driving surface 311, and the limiting surface 322 abuts against a cavity wall of the installation cavity when the protective door 30 is in the first state; when the plug 200 abuts against the driving surface 311 and pushes the protection door 30 to contact with the slide rail 21, the connection between the limiting surface 322 and the driving surface 311 slides along the insertion direction of the plug 200.

It can be understood that the limiting surface 322 is located between the guiding surface 321 and the driving surface 311, two opposite side edges of the limiting surface 322 are respectively connected with the guiding surface 321 and the driving surface 311, when the protection door 30 is in the first state, the limiting surface 322 abuts against a cavity wall of the installation cavity, the cavity wall is adjacent to the surface cover 10, when the plug 200 abuts against the driving surface 311 and pushes the protection door 30 to contact with the sliding rail 21, a connection portion of the limiting surface 322 and the driving surface 311 slides along the cavity wall abutting against the connection portion, i.e. along the insertion direction of the plug 200, so as to further ensure the stability of the protection door 30 in the overturning process, so that the driving surface 311 accurately blocks the insertion hole 13 of the protection door 30 in the first state.

Referring to fig. 2, in an embodiment of the socket 100 of the present invention, the extending direction of the sliding rail 21 is perpendicular to the arrangement direction of the two insertion holes 13, and the sliding rail 21 is located between the two insertion holes 13. With this arrangement, the protection door 30 is not affected by the slide rail 21 during the turning process, so that the protection door 30 can slide along the extending direction of the slide rail 21 after being smoothly turned.

Of course, in other embodiments, the extending direction of the sliding rail 21 and the arrangement direction of the two insertion holes 13 may be parallel or at an angle, as long as it is ensured that the sliding rail 21 does not affect the turning of the protection door 30 and the insertion of the plug 200 into the insertion sleeve 24 in the installation cavity under normal conditions.

Referring to fig. 2, 9 and 11, in an embodiment of the socket 100 of the present invention, two protection ribs 22 are convexly disposed on the cavity wall of the mounting cavity facing the face cover 10, the two protection ribs 22 are respectively located on two sides of the sliding rail 21, the guide surface 321 is provided with two spaced-apart limiting grooves 3212, and when the protective door 30 is in the first state, each protection rib 22 faces a notch of one of the limiting grooves 3212; when the protection door 30 is pushed by a single side to tilt around the slide rail 21, one end of the protection door 30, which is pushed, sinks down, so that one end of one protection rib 22, which faces the notch of the limit groove 3212, enters the corresponding limit groove 3212 and abuts against the groove wall of the limit groove 3212.

It can be understood that, when only one of the two insertion holes 13 is inserted with a foreign object, the protection door 30 tilts around the sliding rail 21 due to single-side pushing, that is, one end of the protection door 30 sinks under a pushing force, and the other end tilts, at this time, the end of the protection door 30 that receives the pushing force sinks, so that one end of the protection rib 22 facing the notch of the limiting groove 3212 enters the corresponding limiting groove 3212 and abuts against the groove wall of the limiting groove 3212, thereby not only limiting the protection door 30 from tilting around the sliding rail 21, but also limiting the protection door 30 from sliding along the extending direction of the sliding rail 21, and further limiting the foreign object from being inserted into the installation cavity, so as to contact with the insertion sleeve 24 in the installation cavity to cause electric shock, thereby effectively preventing the risk of accidental electric shock of children.
