In order that the above objects, features and advantages of the utility model will be readily understood, a more particular description of the utility model will be rendered by reference to the appended drawings. In the following description, numerous specific details are set forth in order to provide a thorough understanding of the present utility model. The present utility model may be embodied in many other forms than described herein and similarly modified by those skilled in the art without departing from the spirit of the utility model, whereby the utility model is not limited to the specific embodiments disclosed below.

Referring to fig. 1 to 5, a socket 10 is provided, which includes a base 100, a panel 200 and a protection door 300. The panel 200 is covered on the base 100, and the panel 200 is provided with a jack 210 for inserting the plug 20. As shown in fig. 3, either one of the protection door 300 and the seat body 100 is provided with a guide protrusion 410, and the other is provided with a guide recess 420. For example, in one embodiment, the protection door 300 is provided with a guide recess 420, and the seat 100 is provided with the guide recess 420. For another example, in another embodiment, the protection door 300 is provided with a guide protrusion 410, and the seat 100 is provided with a recess therein. At least part of the guide recess 420 is used for storing a lubricating body, and the protection door 300 is slidably matched with the guide protrusion 410 through the guide recess 420 to slide to a first position and a second position relative to the base 100, wherein the protection door 300 shields the jack 210 in the first position, and the protection door 300 does not shield the jack 210 in the second position. The socket 10 of the present application is to be understood in a broad sense, and may be considered as a panel socket 10 for installing a wall or a desk, a extension cord, or the like.

Alternatively, the jack 210 may include a two-plug jack, a three-plug jack, and the like. The number of the protection doors 300 may be plural, and one protection door 300 may be used to block or open two insertion holes, which may mean one or two of the insertion holes 210 to block or open two insertion holes. Similarly, another protection door may be used to block or open the three-way jack, and may also refer to one, two, or three of the jacks 210 that block or open the three-way jack.

Alternatively, the plug 20 may refer to a two-pole plug 20, or may refer to a three-pole plug 20, where two plug jacks 210 are used for inserting the two-pole plug 20, and three plug jacks 210 are used for inserting the three-pole plug 20; the plug 20 may also refer to a plug 20 having a flat blade or a cylindrical plug pin.

The socket 10 has a protection door 300 for controlling the opening and closing of the insertion hole 210. When the external plug 20 is not inserted into the socket 10, the protection door 300 is in the first position, and the protection door 300 may shield the insertion hole 210 to protect the internal structure of the socket 10. When the external plug 20 is inserted, the protection door 300 can be moved to the second position to open the jack 210 under the action of external force, and the plug 20 can be inserted into the socket 10 to achieve electrical connection. During the use of the socket 10, at least part of the structure of the guiding recess 420 can play a role of storing lubrication bodies (such as lubricating oil, lubricant, grease, etc.), so as to ensure the effective supply of the lubrication bodies between the guiding recess 420 and the guiding protrusion 410, further ensure the effective lubrication between the protection door 300 and the seat 100, and prevent the clamping phenomenon. In addition, if the protection door 300 is frequently slid in a certain usage scenario, a certain amount of heat may be generated due to sliding friction, and the sufficient lubrication body may absorb the heat, so that the heat may not affect the fatigue resistance of each component of the socket 10.

Specifically, as shown in fig. 3, 4, and 5, in some of the embodiments, the guide recess 420 includes a guide chute 421 and a storage groove 422 in communication with the guide chute 421. The groove wall of the guide chute 421 is adapted to slidably abut against the surface of the guide projection 410. During use, debris may be generated between the guiding concave portion 420 and the guiding convex portion 410, and the blocking phenomenon of the protection door 300 may be caused by the accumulation of the debris, so that the socket 10 loses the use function, and the storage groove 422 of the present application can be used for storing the lubricating body and the debris, so that the possibility of blocking of the protection door 300 is further reduced.

More specifically, as shown in fig. 4 and 5, in some of the embodiments, the groove wall of the guide chute 421 is concaved inward to form a storage groove 422. Such a structural arrangement may be considered as having a greater depth of the storage groove 422 than the guide chute 421 in the radial direction to ensure that the storage groove 422 has a space for storing the lubricating body.

More specifically, as shown in fig. 4, in some of the embodiments, the storage groove 422 is provided to extend in the circumferential direction of the guide chute 421. Such a configuration can increase the storage space of the storage tank 422 and store more lubrication bodies, chips, and the like.

More specifically, as shown in fig. 4, in some of the embodiments, the storage groove 422 is located at the middle of the guide chute 421 in the length extending direction L of the guide chute 421. The storage groove 422 is located in the middle of the guide chute 421, so that on one hand, the lubrication in the storage groove 422 can be prevented from overflowing, and on the other hand, when the protection door 300 slides back and forth, the guide protrusion 410 also slides back and forth in the guide chute 421, so that the lubrication, scraps and the like can be driven into the storage groove 422 in the middle of the guide chute 421.

Referring to fig. 3, in some embodiments, the protection door 300 is provided with a guiding inclined plane 310 at a side close to the panel 200, and an included angle between the guiding inclined plane 310 and the panel 200 is an acute angle, and the guiding inclined plane 310 is configured to drive the protection door 300 to slide to the second position under the supporting of the plug 20. When the external plug 20 is inserted into the housing 100 from the insertion hole 210, the plug 20 moves the protection door 300 to the second position in a direction away from the insertion hole 210 by abutting the guide slope 310 to open the insertion hole 210.

Specifically, as shown in fig. 3, in some embodiments, two guide inclined planes 310 on the protection door 300 may be provided, the two guide inclined planes 310 are axisymmetrically distributed with the central axis of the protection door 300 as a symmetry axis, and the two guide inclined planes 310 may be considered to be disposed in the same direction and located on the left and right sides of the guide recess 420 of the protection door 300, respectively. Taking the two-insertion hole 210 of fig. 1 as an example, two guide inclined planes 310 of the protection door 300 are positioned at the back of the panel 200 and correspond to the two-insertion hole 210 in position. When the two-pole plug 20 extends into the base 100 along the two-pole jack 210, the two inserting pieces on the two-pole plug 20 can simultaneously abut against the two guiding inclined planes 310 of the protection door 300, so that the protection door 300 moves to the second position along the direction away from the two-pole jack 210 to open the two-pole jack 210.

Referring to fig. 3 and 5, in some embodiments, the socket 10 further includes an elastic member 500, one end of the elastic member 500 abuts against the panel 200 or the base 100, the other end of the elastic member 500 abuts against a side of the protection door 300 opposite to the inclined surface 310, and the elastic member 500 is configured to provide an elastic restoring force to slide the protection door 300 to the first position. When the plug 20 is pulled out from the housing 100, the protection door 300 can be automatically reset to the first position under the supporting of the elastic member 500 to block the jack 210.

Specifically, as shown in fig. 3, in some embodiments, a limiting rib 320 is disposed on a side of the protection door 300 abutting against the elastic member 500, and the elastic member 500 is fixed to the protection door 300 by being sleeved on the limiting rib 320. The elastic member 500 may refer to, but is not limited to, a return spring. The elastic member 500 is fixed to the protective door 300 by being sleeved on the limit bead 320. The spacing protruding rib 320 can make the elastic member 500 reliably fixed with the protection door 300, avoid the position of the elastic member 500 to deviate, and ensure the normal operation of the elastic member 500.

More specifically, as shown in fig. 3, in some embodiments, the cross section of the limiting bead 320 is cross-shaped, and one end of the elastic member 500 sleeved on the limiting bead 320 may be installed in an interference fit with the limiting bead 320. Such a structural arrangement may further enhance the firmness of the connection between the elastic member 500 and the protective door 300.

Referring to fig. 3 and 6, in some embodiments, the socket 10 further includes a plug housing 600 disposed in the base 100, and the plug housing 600 includes a main body 610 and a plug portion 620 for plugging in the plug 20.
