Detailed Description

In order to make the technical solutions and advantages of the present application clearer, the following will describe the embodiments of the present application in further detail with reference to the accompanying drawings.

As shown in fig. 1 and 10, the present embodiment provides a socket panel 100, and the socket panel 100 generally constitutes a socket together with a socket body 200. The socket panel 100 has a USB opening 112, and the socket body 200 (shown in fig. 3) associated with the socket panel 100 correspondingly has a USB socket 201, so that the USB plug 300 can be inserted into the USB socket 201 (shown in fig. 8) through the USB opening 112. The receptacle panel 100 may also have other structures such as two-hole jacks and/or three-hole jacks. The structure of the receptacle panel 100 according to the embodiment of the present application and its improvements and advantages will be described in detail below.

Referring to fig. 1 and 10, the socket panel 100 has a guide groove 111, a USB opening 112, and a protective door assembly.

The protective door assembly includes a protective door body 121, as shown in fig. 1 and 10, the protective door body 121 is movably located in an opening direction of the USB opening 112 for shielding or exposing the USB opening 112. That is, in the state shown in fig. 1 and 13, the protective door body 121 is positioned above or below the USB opening 112, so that the USB plug 300 can be blocked from being directly inserted into the USB socket 201 through the USB opening 112 from the opening direction of the USB opening 112 (i.e., the direction perpendicular to the face cover 110 or perpendicular to the boss top surface 132); in the state shown in fig. 7 and 13, the protective door body 121 is pushed away from the position covering the USB opening 112, and when the protective door body 121 is pushed away, the USB opening 112 and the USB socket 201 located below the USB opening 112 are exposed, so that the USB plug 300 can pass through the USB opening 112 and be inserted into the USB socket 201.

According to actual needs, the number of the USB openings 112 on the socket panel 100 may be one, two, three or more, and accordingly, the USB openings 112 may correspond to the protection door bodies 121 one by one, or at least two USB openings 112 may correspond to one protection door body 121 at the same time, that is, at least two USB openings 112 are covered by one protection door body 121. When two or more USB openings 112 are covered by one protection door body 121, if the protection door body 121 is pushed to avoid one USB plug 300 to be inserted, all USB sockets 201 covered by the protection door body 121 are exposed on the socket panel 100. At this time, other USB plug 300 may be inserted into the corresponding USB socket 201 after being guided by the guide groove 111 and the protrusion 113, or may be inserted into the USB socket 201 directly from the opening direction of the USB opening 112 through the USB opening 112.

The above-mentioned guiding of the guiding groove 111 and the protrusion 113 means that the guiding groove 111 and the protrusion 113 are used in combination to correct the insertion posture of the USB plug 300, so as to guide the USB plug 300 to be correctly inserted into the USB socket 201 (even if the USB plug 300 is inserted in the forward direction instead of the reverse direction). Referring to fig. 1, the guide groove 111 is adjacent to the USB opening 112, the bottom wall of the guide groove 111 has a protrusion 113 thereon, and the bottom wall of the guide groove 111 and the protrusion 113 are fitted to the USB plug 300. Generally, as shown in fig. 1 and 10, the guide slot 111 may be adjacent to the USB opening 112 in a length direction thereof, but in other embodiments, the guide slot 111 may be adjacent to the USB opening 112 in a width direction thereof. While for the two arrangements of the guide groove 111, the protrusion 113 is required to be disposed at different positions in the guide groove 111: referring to fig. 8, when the guide groove 111 is disposed adjacent to it in the length direction of the USB opening 112, the protrusion 113 is located in the length direction of the tongue-piece portion of the USB socket 201; when the guide groove 111 is provided adjacent to it in the width direction of the USB opening 112, the size of the guide groove 111 may be made equal to the size of the USB socket 201, and the position of the protrusion 113 in the guide groove 111 corresponds to the position of the tongue piece portion of the USB socket 201 in the USB socket 201, for example, if the tongue piece portion of the USB socket 201 is located in the lower half of the USB socket 201, the protrusion 113 is also located in the lower half of the guide groove 111, and vice versa.

Further, in order to allow the protrusion 113 to be accommodated in the hollow portion 301 of the USB plug 300, the length of the protrusion 113 is generally set to be smaller than the length of the hollow portion 301 of the USB plug 300 (sometimes, the former may be larger than the latter, and only a part of the protrusion 113 enters the hollow portion 301 of the USB plug 300), and the width of the protrusion 113 is generally set to be smaller than the width of the hollow portion 301 of the USB plug 300. Generally, the longitudinal direction of the projection 113 coincides with the longitudinal direction of the USB socket 201, and the width direction of the projection 113 coincides with the width direction of the USB socket 201.

As such, when the USB plug 300 is being inserted, as shown in fig. 9 and 13, the protrusion 113 can be received in the hollow portion 301 of the USB plug 300; when the USB plug 300 is reversely inserted, the protrusion 113 can abut against the solid portion 302 of the USB plug 300. The protrusion 113 is received in the hollow portion 301 of the USB plug 300, which means that the protrusion 113 and the protection door body 121 are not closely adjacent to each other but have a space 123, so that the sidewall of the hollow portion 301 of the USB plug 300 can enter the space 123. Next, the USB plug 300 can move from one end of the guide groove 111 adjacent to the USB opening 112, and during the movement, the first sidewall 303 of the USB plug 300 contacts with the side end surface of the shutter body 121 and applies a force, thereby gradually pushing open the shutter body 121. When the protrusion 113 abuts against the solid portion 302 of the USB plug 300, it means that the USB plug 300 cannot enter the guiding groove 111, the sidewall of the hollow portion 301 of the USB plug 300 cannot enter the space 123, and the protection door body 121 cannot be pushed open.

The term "forward insertion" in the present application means insertion of the USB plug 300 when the hollow portion 301 of the USB plug 300 is aligned with the tongue portion of the USB socket 201, and the solid portion 302 of the USB plug 300 is aligned with the hollow portion of the USB socket 201; "reverse insertion" means insertion of the USB plug 300 when the hollow portion 301 of the USB plug 300 is aligned with the hollow portion of the USB socket 201 and the solid portion 302 of the USB plug 300 is aligned with the tongue-piece portion of the USB socket 201. The first sidewall 303 of the USB plug 300 is a sidewall that contacts a side end surface of the shutter body 121 close to the guide groove 111 when the USB plug 300 is inserted forward, and when the USB plug 300 is inserted backward, the first sidewall 303 is away from the shutter body 121, and the second sidewall 304 opposite to the first sidewall 303 is close to the shutter body 121.

In the embodiment of the present application, due to the blocking of the protective door body 121, the USB plug 300 cannot directly pass through the USB opening 112, but only pushes the protective door body 121 open by being inserted into the guide slot 111 and then moving from the guide slot 111 to the USB opening 112, and then passes through the USB opening 112 to enter the USB socket 201. In the process of inserting the USB plug 300 into the guide groove 111, the protrusion 113 disposed on the bottom wall of the guide groove 111 can limit the insertion posture of the USB plug 300 to be forward insertion, so as to prevent the USB socket 201 from being reversely inserted, and avoid the damage to the USB socket 201 caused by frequent reverse insertion.

In some implementations of the embodiment of the present application, the width of the guide slot 111 is adapted to the width of the USB plug 300, the orthographic projection of the protrusion 113 on the bottom wall of the guide slot 111 is located within the orthographic projection of the hollow portion 301 on the bottom wall of the guide slot 111 when the USB plug 300 is inserted, and has an overlapping area with the orthographic projection of the hollow portion 302 on the bottom wall of the guide slot 111 when the USB plug 300 is inserted backwards. The width of the guide groove 111 is adapted to the width of the USB plug 300, which means that the width of the guide groove 111 is equal to or slightly larger than the width of the USB plug 300, so that the USB plug 300 can enter the guide groove but the margin in width is not large, and thus the movement to the USB opening 112 does not deviate from the direction to cause the insertion deviation. The orthographic projection of the protrusion 113 on the bottom wall of the guide groove 111 is positioned in the orthographic projection of the hollow part 301 on the bottom wall of the guide groove 111 when the USB plug 300 is inserted, and due to the limitation of the width direction, the protrusion 113 can enter the hollow part 301 when the USB plug 300 is inserted; if the orthogonal projection of the solid portion 302 on the bottom wall of the guiding slot 111 has an overlapping area when the USB plug 300 is reversely inserted, due to the limitation of the width direction, the solid portion 302 of the USB plug 300 will inevitably abut against the protrusion 113, so that the bottom walls of the USB plug 300 and the guiding slot 111 are separated by the protrusion 113, and the USB plug 300 can not enter the guiding slot 111 substantially, and certainly, there is no possibility of continuously pushing the protection door body 121 open.

The structure of the protrusion 113 will be further described and illustrated with reference to fig. 3, 7, 9 and 11.

In the process of pushing the USB plug 300 off the protective door body 121, the second sidewall 304 of the USB plug 300 needs to slide on the surface of the protrusion 113 and eventually pass over the protrusion 113. In order to make the second side wall 304 of the USB plug 300 slide from one side of the protrusion 113 to the other side more easily, in some implementations of the embodiment of the present application, as shown in fig. 3 and 11, the side end wall of the protrusion 113 away from the USB opening 112 is a slope, and the slope is higher and higher closer to the USB opening 112, so that when the USB plug 300 moves toward the USB opening 112, the second side wall 304 of the USB plug 300 can move more smoothly over the protrusion 113 and toward the USB opening 112 by means of the slope, and the risk that the first side wall 303 of the USB plug 300 slips off on the side end surface of the protection door body 121 is reduced. The inclined surface is inclined with respect to the bottom wall of the guide groove 111, and the form of the inclined surface may include a flat inclined surface and a curved inclined surface.

After the design of the side end wall of the protrusion 113 far from the USB opening 112 is completed, in consideration of the convenience of processing of the protrusion 113, the side end wall of the protrusion 113 near the USB opening 112 may be directly connected to the side end wall far from the USB opening 112, so that a sharp angle shape is formed at the top of the protrusion 113, which corresponds to the protrusion 113 being inclined in a manner that the closer to the USB opening 112 is, the higher the height is, and accordingly, the protrusion 113 may have a structure with an angular top, such as a triangular structure.

In some implementations of embodiments of the present application, the top of the protrusion 113 is a plane that is parallel to the bottom wall of the guide groove 111 or is inclined in a manner that the closer to the USB opening 112, the higher. Wherein, when the plane is parallel to the bottom wall of the guide groove 111, as shown in fig. 9, the cross section of the protrusion 113 is shaped like a trapezoid; when the plane is inclined in such a manner that the plane is closer to and higher than the USB opening 112, the inclination angle of the plane is generally smaller than the inclination angle of the side end wall of the protrusion 113 away from the USB opening 112. Thus, the second end wall 304 of the USB plug 300 can smoothly transit over the protrusion 113 when the USB plug 300 is inserted forward, and the second side wall 304 of the USB plug 300 can be prevented from contacting the side end surface of the protection door body 121 due to the reverse inclination when the USB plug 300 is inserted backward. In some embodiments, the junction of the side end wall and the top of the protrusion 113 away from the USB opening 112 may be designed to be rounded, so that the transition of the second end wall 304 on the protrusion 113 can be smoother.

In different embodiments, the socket panel 100 provided by the embodiment of the present application may have different configurations. The structure and advantages of the receptacle panel 100 according to the embodiment of the present application will be further described and explained with reference to fig. 1 to 15, wherein fig. 1 to 9 show the first receptacle panel 100 according to the embodiment of the present application, and fig. 10 to 15 show the second receptacle panel 100 according to the embodiment of the present application, which are different in the arrangement of the guide groove 111, the USB opening 112 and the protection door assembly, but the basic principle is similar as described above.

The first socket panel 100 provided in the embodiment of the present application is a split structure. As shown in fig. 1, 4 and 6-8, the receptacle faceplate 100 may include a face cover 110. Referring to fig. 1, a guide groove 111 is adjacent to the USB opening 112 and is located on the face cover 110, and one end of the guide groove 111 communicates with the USB opening 112. That is, the guide groove 111 and the USB opening 112 are adjacent to each other on the same plane and communicate with each other, and the USB plug 300 can move from the position where the guide groove 111 communicates with the USB opening 112 to above the USB opening 112.

In one implementation of the embodiment of the present application, as shown in fig. 2 and 3, the socket panel 100 further includes a pressing plate 120, the surface cover 110 is stacked on the pressing plate 120, and the surface cover 110 covers the pressing plate 120, and the two can be fixed together by bonding, snapping, or bolting. Typically, the face cover 110 and the platen 120 are made primarily of an insulating material to provide mechanical support and mechanical connection. The pressing plate 120 is used to limit the electrical components in the socket body 200 and prevent the electrical components from moving in the socket body 200. The structure of the platen 120, which is not relevant to the present improvement, is not described in detail herein. In some embodiments, as shown in fig. 1 and 2, the receptacle panel 100 may further include a cover plate 140 disposed at the outer periphery of the face cover 110 to improve safety and appreciation.

In some implementations of the embodiments of the present application, the guide groove 111 is integrally a portion of the concave portion of the face cover 110, and the protrusion 113 is disposed on the bottom wall of the guide groove 111, that is, on the face cover 110. When the face cover 110 is detached from the receptacle panel 100, the guide groove 111 and the protrusion 113 as an additional structure of the face cover 110 are also detached together with the face cover 110.

However, in another implementation manner of the embodiment of the present application, as shown in fig. 8, the face cover 110 has a first opening 114, the first opening 114 is an upper opening of the guide groove 111, a surface of the pressing plate 120 exposed to the first opening 114 forms a bottom wall of the guide groove 111, and the first opening 114 is adjacent to and communicates with the USB opening 112. That is, since the surface cover 110 has the first opening 114, when the surface cover 110 covers the pressing plate 120, the surface of the pressing plate 120 is exposed from the first opening 114, and since the surface cover 110 has a certain thickness, the exposed surface of the pressing plate 120 and the first opening 114 together constitute the guide groove 111, wherein the first opening 114 provided in the surface cover 110 serves as an upper opening of the guide groove 111, the side wall of the first opening 114 serves as a side wall of the guide groove 111, and the corresponding portion of the surface of the pressing plate 120 serves as a bottom wall of the guide groove 111. The guide groove 111 is formed to limit the starting position of the USB plug 300 pushing the protective door body 121 to the range of the bottom wall of the guide groove 111, and in order to make the USB plug 300 easily inserted into the guide groove 111, the size of the guide groove 111 may be slightly larger than that of the USB plug 300, but the size of the guide groove 111 may not be too large to avoid entering the guide groove 111 by avoiding the obstruction of the protrusion 113 when the USB plug 300 is inserted backwards.

With continued reference to fig. 8, the pressing plate 120 has an opening corresponding to the USB opening 112, and the USB socket 201 is located below and connected to the opening, so that the USB plug 300 can be inserted into the USB socket 201 after sequentially passing through the USB opening 112 and the opening.

The USB plug 300 in the related art includes an insulating hand-held portion and an insertion portion made of metal, wherein one end of the hand-held portion is connected to the data line, the other end of the hand-held portion is connected to the insertion portion, and the cross-sectional size of the hand-held portion is larger than that of the insertion portion. When the USB plug 300 is plugged into the USB socket 201, only the insertion portion enters the USB socket 201. Therefore, in order to facilitate the insertion of the USB plug 300 into the USB socket 201, in some embodiments, as shown in fig. 8, the size of the USB opening 112 may be larger than the size of the corresponding USB socket 201, that is, larger than the size of the corresponding opening on the pressing plate 120, and a part of the pressing plate 120 may be exposed from the USB opening 112, so that when the USB plug 300 is inserted into the USB socket 201, the insertion portion of the USB plug 300 may completely enter the USB socket 201, and the end surface of the end of the hand-held portion connected to the insertion portion may contact the pressing plate 120 exposed from the USB opening 112.

In addition, as can be seen from fig. 1 and 2, the protection door body 121 is located between the face cover 110 and the pressure plate 120, and is located between the USB opening 112 and the opening on the pressure plate 120 in the initial state, where the initial state refers to a position where the protection door body 121 is located to shield the USB opening 112. Before the protective door body 121 is pushed open, as shown in fig. 1, the user cannot see the USB socket 201 below the USB opening 112, and only after the protective door body 121 is pushed open, as shown in fig. 8, the USB socket 201 is exposed below the USB opening 112. The dimension of the protection door body 121 in at least one direction can be generally larger than the dimension of the USB opening 112, so that the protection door body 121 is clamped between the face cover 110 and the pressing plate 120, and can only move on the plane where the protection door body is located, but cannot pass through the USB opening 112 or the opening of the pressing plate 120 to turn over. In order to prolong the service life of the protective door body 121, the protective door body 121 may be made of a material having high strength and strong impact resistance, and in some outdoor locations, a material having strong oxidation resistance and/or ultraviolet resistance may be further selected.

As is apparent from the foregoing description, in the embodiment of the present application, the protective door body 121 is provided mainly to prevent the user from directly inserting the USB plug 300 into the USB socket 201 without determining a correct insertion posture through the guide groove 111 and the protrusion 113 each time the USB plug 300 is inserted into the USB socket 201. Therefore, each time the USB plug 300 is pulled out of the USB socket 201, the protection door body 121 needs to be moved to a position for shielding the USB opening 112. Therefore, in some implementations of embodiments of the present application, as shown in fig. 2 and 3, the protective door assembly further includes a return elastic device 122, one end of the return elastic device 122 is connected to the pressure plate 120, and the other end is connected to the protective door body 121, so that the protective door body 121 is relatively movably connected to the pressure plate 120. The return elastic device 122 may be a compression spring configured to return the protection door body 121 to a position of shielding the USB opening 112. That is, after the USB plug 300 is inserted into the USB socket 201, the protective door body 121 cannot be returned to the position for shielding the USB opening 112 due to the pushing of the first sidewall 303 of the USB plug 300, but once the USB plug 300 is pulled out, the elastic reset device 122 can push the protective door body 121 to return to the position for shielding the USB opening 112, so that before the USB plug 300 is inserted into the USB socket 201, the user needs to correct the insertion posture of the USB plug 300 to be the same as that of the protective door body 121 inserted into the USB opening 112 and push the protective door body 121 open, and the protective door body 121 is prevented from being assumed by not returning to the position for shielding the USB opening 112. Meanwhile, the protective door body 121 can also function to protect the USB socket 201, for example, from water and dust.

For example, as shown in fig. 2, the protection door body 121 may have a structure similar to a rectangle including a first side end adjacent to the protrusion 113 and a second side end opposite to the first side end, the first side end being an end surface of the first side end. As shown in fig. 3, a stopper 1211 protruding in a direction perpendicular to the receptacle panel 100 may be further provided above the first side end in order to easily push the protection door body 121 to escape from the USB plug 300. The stopper 1211 increases a contact area of the first sidewall 303 of the USB plug 300 with the first side end surface of the shutter body 121, and can prevent the USB plug 300 from slipping off.

Fig. 9 shows a sectional structure of a protrusion 113, and as can be seen from fig. 9, in some implementations of the present application, the height of the side end wall of the protrusion 113 adjacent to the protection door body 121 is greater than or equal to the height of the side end surface (i.e., the height of the first side end surface) of the protection door body 121 adjacent to the protrusion 113, so as to ensure that the USB plug 300 cannot push the protection door body 121 open when moving on the top of the protrusion 113 after the top of the protrusion 113 contacts the solid portion 302 of the USB plug 300. In addition, when the stopper 1211 is disposed above the first side end surface of the protection door body 121, the height of the side end wall of the protrusion 113 adjacent to the protection door body 121 is not less than the vertical height of the top of the stopper 1211 from the pressing plate 120.

In the first socket panel 100, if the USB plug 300 is inserted positively, the USB plug 300 can enter the guide groove 111, the protrusion 113 enters the hollow portion 301 of the USB plug 300, the first sidewall 303 of the USB plug 300 enters the gap 123 between the protrusion 113 and the protective door body 121, the USB plug 300 is moved toward the USB opening 112, the first sidewall 303 contacts the first sidewall of the protective door body 121, and then the USB plug 300 is continuously moved with the direction unchanged, so that the protective door body 121 is gradually pushed open and the USB socket 201 located below the USB opening 112 is exposed, and the USB plug 300 is inserted into the USB socket 201, and during the movement of the USB plug 300 toward the USB opening 112, the second sidewall 304 of the USB plug 300 slides over the sidewall (and top) of the protrusion 113 away from the protective door body 121. After the USB plug 300 is inserted into the USB socket 201, the first side surface of the protective door body 121 always abuts against the first side wall 303 of the USB plug 300; when the USB plug 300 exits the USB opening 112, the protection door body 121 is pushed by the elastic reset device 122 to return to a position covering the USB opening 112.

If the USB plug 3 is inserted reversely, the top of the protrusion 113 abuts against the solid portion 302 of the USB plug 300, so that the USB plug 300 cannot enter the guiding slot 111, and accordingly, the first sidewall 303 of the USB plug 300 cannot enter the gap 123 between the protrusion 113 and the protective door body 121, and cannot push the protective door body 121 open, and cannot be inserted into the USB socket 201. Therefore, the first socket panel 100 achieves the effect of preventing the USB socket 201 from being inserted backwards, and avoids the damage to the USB socket 201 caused by frequent reverse insertion.

The second socket panel 100 provided in the embodiment of the present application may be an integrated structure, as shown in fig. 10, the socket panel 100 has a boss 130, and the guide slot 111, the USB opening 112 and the protection door assembly are located on the boss 130. The number of the bosses 130 on the receptacle panel 100 is generally one, and may be two, three or more according to actual needs. For convenience of description, the socket panel 100 is provided with one projection 130, and those skilled in the art can easily deduce the situation when two, three or more projections 130 are provided on the socket panel 100 from the description.

As shown in fig. 10, the receptacle panel 100 has a boss 130 thereon, and the boss 130 includes a boss sidewall 131 and a boss top surface 132, and the boss sidewall 131 and the boss top surface 132 are obliquely connected. In the embodiment of the present application, the socket panel 100 and the boss 130 may be formed as separate bodies and then connected, or they may be integrally formed and combined together. According to actual needs, the boss 130 can be filled into a solid structure to have higher strength and pressure-bearing capacity, and can also be not filled to reserve a cavity to save production cost and reduce self weight.

Generally, the top surface 132 is parallel to the socket panel 100, so that the insertion paths of the plugs are not easily crossed and blocked when other jacks are provided on the socket panel 100, and of course, in the case that the insertion paths of the plugs are planned, the top surface 132 may be designed to be non-parallel to the plane of the socket panel 100. The oblique connection between the sidewall 131 and the top 132 means that the sidewall 131 and the top 132 are not in the same plane, including the case where the sidewall 131 is perpendicular to the top 132, and also including the case where the sidewall 131 is not perpendicular to the top 132.

In some implementations of embodiments of the present application, as shown in fig. 13, the boss top surface 132 is parallel to the receptacle panel 100, one end of the boss sidewall 131 is connected to an edge of the boss top surface 132, the other end is connected to a surface of the receptacle panel 100, and the other end of the boss sidewall 131 is located outside an orthographic projection of the boss top surface 132 on the receptacle panel 100. The boss sidewall 131 is positioned outside the boss top surface 132 at this time, and is inclined so as to be higher as it gets closer to the boss top surface 132.

As shown in fig. 10, the guide groove 111 is located on the boss side wall 131, the USB opening 112 is located on the boss top surface 132, and the guide groove 111 extends to the edge where the boss side wall 131 meets the boss top surface 132. The protrusion 113 is located on the bottom wall of the guide groove 111, i.e., on the boss side wall 131. The USB plug 300 may be moved over the USB opening 112 through the junction of the boss sidewall 131 and the boss top surface 132.

With continued reference to fig. 10, the plurality of guide slots 111 are formed in the side wall 131 of the boss, the guide slots 111 correspond to the USB openings 112 one by one, a protrusion 113 is formed on the bottom wall of each guide slot 111, and the protrusion 113 is located in the length direction of the tongue portion of the USB socket 201 and has a gap 123 with the protection door body 121. The top surface 132 has a plurality of USB openings 112 and a protection door body 121, and the protection door body 121 can cover the plurality of USB openings 112. In this case, as shown in fig. 12, all USB openings 112 may be uniformly arranged on the top surface 132 of the boss along the width direction of the USB openings 112, or may also be non-uniformly arranged or even staggered in the width direction of the USB openings 112, for example, in a case where a switch for controlling on/off of the USB socket 201 is provided beside the corresponding one or more USB sockets 201, and the guide groove 111 and the protrusion 113 are always provided on the side wall 131 of the boss corresponding to the USB openings 112. Similarly, all the USB openings 112 on the top surface 132 of the boss may also be arranged along the length direction of the USB openings 112, the arrangement manner of the USB openings is similar to the arrangement manner along the width direction, and the arrangement manner of the guide slot 111 and the protrusion 113 is also similar, which is not described herein again.

Unlike the corresponding relationship between the protective door body 121 and the USB opening 112 shown in fig. 10, in other embodiments of the present application, when the boss top surface 132 has at least two USB openings 112, the USB openings 112 may also correspond to the protective door bodies 121 one to one. At this time, except for the change of the number and the shielding range of the protection door bodies 121, the arrangement and the direction of each USB opening 112 and the arrangement and the direction of the guide groove 111 and the protrusion 113 are not different from the case when at least two USB openings 112 are shielded by one protection door body 121, and the description thereof is omitted herein.

With the above-mentioned second socket panel 100 structure, as shown in fig. 13, the size of the guiding slot 111 may be smaller than the size of the end face of the USB plug 300, but it is still necessary to keep the width of the guiding slot 111 matching with the width of the USB plug 300, so that when the USB plug 300 is inserted, although the second side wall 304 of the USB plug 300 is located outside the guiding slot 111 and contacts with the surface of the socket panel 100, a part of the USB plug 300 may enter the guiding slot 111 on the boss side wall 131, especially the first side wall 303 may enter the space 123, and the USB plug 300 may still push the protection door body 121 open into the USB socket 201.

Of course, in other embodiments of the present application, the width of the boss side wall 131 (the width direction refers to a direction from the end of the boss side wall 131 connected to the surface of the receptacle panel 100 to the end connected to the boss top surface 132) may be increased, so that the length and width of the guide groove 111 are adapted to the length and width of the USB plug 300, so that when the USB plug 300 is being inserted, the USB plug 300 can completely enter the guide groove 111, and the end surface of the open end of the USB plug 300 can contact the bottom wall of the guide groove 111.

Referring to fig. 11, the plurality of guide grooves 111 in fig. 11 may be integrated into one guide groove 111, that is, the boss sidewall 131 has one guide groove 111, the bottom wall of the guide groove 111 is provided with a plurality of protrusions 113, and each protrusion 113 corresponds to one USB opening 112. Further, in order to illustrate the insertion position of the USB plug 300 in the guide groove 111 with respect to the protrusions 113, a mark may be provided on one side of each protrusion 113 or a region may be divided based on the corresponding position of each USB opening 112 in the guide groove 111 for indication. For example, a rectangular shadow may be painted at an adjacent position of the protrusion 113 corresponding to the hollow portion of the USB socket 201 to indicate that the rectangular shadow corresponds to the solid portion 302 of the USB plug 300. For another example, the orthographic projection of each USB opening 112 on the boss sidewall 131 is used as a basis for area division, and the area where the orthographic projection is located is marked to be used as the area to be inserted of the USB plug 300.

In some implementations of the embodiments of the present application, as shown in fig. 10, the receptacle panel 100 further includes a rotation shaft 133 on the boss 130, and the first end of the protection door body 121 is rotatably connected to the rotation shaft 133.

In the above embodiment, the second side end of the protection door body 121 is fixed to the rotation shaft 133, and the protection door body 121 is fixed to the boss 130. The protective door body 121 is gradually pushed away to avoid the USB plug 300, and actually, the protective door body 121 gradually rotates in a direction perpendicular to the boss top surface 132 with the second side end as a fulcrum, and a space capable of accommodating the USB plug 300 is formed between the protective door body 121 and the boss top surface 132. In order to realize that the protection door body 121 can still shield the USB opening 112 after the USB plug 300 exits the USB socket 201, the rotation shaft 133 is relatively rotatably sleeved with the torsion spring 134, one end of the torsion spring 134 is connected with the boss 130, and the other end of the torsion spring 134 is connected with the protection door body 121, when the protection door body 121 rotates, the torsion spring 134 is also deformed to generate a torsion force, and the torsion force can strain the protection door body 121 towards the boss 130, so that the protection door body 121 returns to the position for shielding the USB opening 112, and the protection door body 121 is prevented from forming a virtual shape because the protection door body 121 cannot return to the position for shielding the USB opening 112.

Referring to fig. 13, an end of the protective door body 121 opposite to the first end of the protective door body 121 is beyond the corresponding edge of the boss sidewall 131 or aligned with the corresponding edge of the boss sidewall 131, so that when the first sidewall 303 of the USB plug 300 enters the space 123 and contacts the bottom wall of the guide groove 111, the first sidewall 303 can also be brought into contact with the first side end surface of the protective door body 121 by moving the USB plug 300, thereby pushing open the protective door body 121. However, although the end of the protective door body 121 opposite to the first end of the protective door body 121 exceeds the corresponding edge of the boss sidewall 131, the exceeding portion may not exceed a set distance, for example, 1mm, so as to prevent the second sidewall 304 from entering under the exceeding portion of the protective door body 121 and pushing the protective door body 121 when the USB plug 300 is inserted reversely.

In the second socket panel 100, taking the structure shown in fig. 10 as an example, if the USB plug 300 is inserted in the forward direction, as shown in fig. 14 and 15, the upper half of the protrusion 113 may enter the hollow 301 of the USB plug 300, the first sidewall 303 may enter the gap 123, the USB plug 300 may be moved toward the USB opening 112, the first sidewall 303 may contact the first side surface of the protective door body 121, and then the USB plug 300 may be continuously moved while maintaining the direction, so that the protective door body 121 covering the USB opening 112 is gradually rotated in the direction perpendicular to the boss top surface 132, the USB opening 112 and the USB socket 201 therebelow are exposed, and the USB plug 300 may be inserted into the USB socket 201. During the movement of the USB plug 300 toward the USB opening 112, the second side wall 304 of the USB plug 300 is stroked over the side end wall (and the top) of the protrusion 113 away from the protective door body 121. After the USB plug 300 is inserted into the USB socket 201, the first side surface of the protective door body 121 is always abutted against the first side wall 303 of the USB plug 300; when the USB plug 300 exits the USB opening 112, the protection door body 121 returns to the position covering the USB opening 112 under the torsion of the torsion spring 134.

If the USB plug 300 is inserted reversely, the top of the protrusion 113 contacts with the solid portion 302 of the USB plug 300, so that the USB plug 300 cannot enter the guiding slot 111, and accordingly, the first sidewall 303 of the USB plug 300 cannot enter the gap 123 between the protrusion 113 and the protection door body 121, and cannot push the protection door body 121 open, so that the USB plug cannot be inserted into the USB socket 201. Therefore, the second socket panel 100 achieves the effect of preventing the reverse insertion of the USB socket 201, thereby avoiding the damage of the USB socket 201 caused by frequent reverse insertion and prolonging the service life.

The embodiment of the application also provides a socket. As shown in fig. 3, the receptacle includes the receptacle panel 100 and the receptacle body 200, and as shown in fig. 7 to 8, the receptacle body 200 has a USB socket 201, and the USB socket 201 corresponds to the USB opening 112. Meanwhile, the socket body 200 may also have other electrical modules, for example, a multi-outlet socket module, a switch module, and the like. The socket can be installed in a household scene and an office scene with small pedestrian volume, such as a bedroom, a living room and an office, but is particularly suitable for being installed in a public place with large pedestrian volume, such as a library, a coffee room, a train station waiting room and an airport waiting room, and provides the electronic equipment with the function of charging the USB interface. Compared with the socket in the prior art, due to the fact that the unique arrangement is carried out on the related structure of the USB socket, the socket provided by the embodiment of the application, particularly the USB socket, can be durable and not easy to damage.

In the present application, it is to be understood that the terms "first", "second", "third", etc. are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implying any number of technical features indicated.

The above description is only for facilitating the understanding of the technical solutions of the present application by those skilled in the art, and is not intended to limit the present application. Any modification, equivalent replacement, improvement and the like made within the spirit and principle of the present application shall be included in the protection scope of the present application.
