[0042] To make the technical solutions and advantages of the present disclosure clearer, the following describes the embodiments of the present disclosure in more detail with reference to the drawings.

[0043] In order to understand the positional relationship of various components in the socket protection door structure of the embodiment of the present disclosure, the direction approaching the jack on the socket panel is defined as the top direction or upper direction, and conversely, the direction away from the jack on the socket panel is defined as the bottom direction or lower direction, based on the state in which the socket protection door structure of the embodiment of the present disclosure is applied to the socket. In the embodiment of the present disclosure, as shown in Figure 1, the first direction D1 is perpendicular to the upper surface of the protection door, and the first direction D1 is considered to be the up-down direction. 。 It should be noted that the term "two sets" in the embodiments of the present invention means that two sets of parts are arranged with a gap between them, and the number of parts included in each set of parts may be one or more. For example, for two sets of spaced apart first vias, the number of first vias in each set may be one or more. In the embodiment of the present disclosure, Figs. 1 and 2 only illustrate the case where each set of first vias 11 includes one first via 11. .

[0044] 2 set The distribution direction D2 of the first vias coincides with the distribution direction from the N-polarity plug bush to the L-polarity plug bush in the socket, and here, the distribution direction from the N-polarity plug bush to the L-polarity plug bush refers to the extension direction from the N-polarity plug bush to the L-polarity plug bush or the extension direction from the L-polarity plug bush to the N-polarity plug bush. set The distribution direction D2 of the first vias can be defined as the left-right direction, that is, the distribution direction from the N-pole plug bush to the L-pole plug bush is the left-right direction. For example, the N-pole plug bush is located on the left side and the L-pole plug bush is located on the right side. Here, the N-pole plug bush and the L-pole plug bush refer to two-pole plug bushes. Of course, the N-pole plug bush and the L-pole plug bush can also belong to a three-pole plug bush, and in a three-pole plug bush, the N-pole plug bush and the L-pole plug bush are each inclined, but one of them is considered to be located on the left side and the other is located on the right side.

[0045] The directional nouns in the embodiments of the present disclosure are merely intended to more clearly describe the relationship between structures, and are not intended to describe absolute orientations. When a product is placed in a different position, the orientation may change, e.g., "up" and "down" may be interchanged.

[0047] FIG. 1 is a structural schematic diagram of an exemplary socket protection door structure according to an embodiment of the present disclosure, which shows the outline of the state from the disassembled state to the assembled state of the socket protection door structure and the local structure of the support base, respectively. According to one aspect of the embodiment of the present disclosure, an embodiment of the present disclosure provides a socket protection door structure, which, as shown in FIG. 1, includes a support base 1, a protection door 2, and an elastic reset member 3, and the support base 1 is provided with two springs corresponding to the N-pole plug bush and the L-pole plug bush of the socket, respectively. set There is a first via 11, that is, 2 set The first via 11 corresponds to the N-pole jack and the L-pole jack of the socket. When used in a socket, the N-pole plug and the L-pole plug are connected to these two set The N-pole plug bush and the L-pole plug bush can be inserted into each other through the first via 11. Illustratively, each set of first vias 11 may include one first via 11 or multiple first vias 11 .

[0048] In the embodiment of the present disclosure, there are one or more protection door assembly areas on the support base 1, and the number of protection door assembly areas corresponds to the number of protection doors in a one-to-one manner, that is, one protection door 2 is installed in each protection door assembly area, and one elastic reset member 3 corresponds to each protection door 2. Here, FIG. 1 shows an example in which two protection door assembly areas are installed on the support base 1. set If protective door 2 is installed, this set Protective door 2 of 1 pair protects the 2-pole plug bushing and other One set of Protects the 3-pole plug bushing. One of the two protective doors 2 set The arrangement and operation of the socket protection door structure according to the embodiment of the present disclosure will now be described.

[0049] In the embodiment of the present disclosure, the protective door 2 is movably connected to the support base 1, as shown in FIG. , protection The protective door 2 has a second via 22, and the protective door 2 has One of two pairs The first via 11 is exposed, and the other One set ofThe first via 11 of the protective door 2 is configured to be sequentially movable along a first direction D1 and a second direction D2 so that the first via 11 of the protective door 2 corresponds to and communicates with the second via 22 of the protective door 2. Here, as shown in FIG. facing the jack of the socket The second direction D2 is perpendicular to the upper surface 21 of the socket. set The elastic reset member 3 is disposed between the support base 1 and the protection door 2 and is used to reset the protection door 2.

[0050] The protective door 2 is movably connected to the support base 1 so that it can move along the support base 1, and the moving protective door 2 can be switched between an initial state and a retreat state. When the protective door 2 is in the initial state, the protective door 2 is set The pin drives the protection door 2 to move, and after the protection door 2 transitions from the initial state to the retracted state, the protection door 2 moves on the support base 1, and the position of the protection door 2 on the support base 1 also changes accordingly, and the position of the protection door 2 on the support base 1 also changes accordingly. 1 pair The first via 11 is exposed, Another pair The first via 11 corresponds to and communicates with the second via 22 in the protective door 2. In this way, when the protective door 2 is in the retracted state, set The first via 11 is actually exposed, i.e., set This allows the pins to be inserted into the corresponding plug bushes from the first vias 11.

[0051] 2 is a schematic diagram of an exemplary socket protection door structure according to an embodiment of the present disclosure, where the upper part shows the protection door in an initial state and the lower part shows the protection door in a retracted state. As shown in FIG. 2, when the protection door 2 is in the initial state, the second via 22 in the protection door panel 201 is connected to the second via 22 in the support base 1. set In this way, the other portion of the protective door panel 201 is offset from the first via 11. setWhen the protection door 2 transitions from the initial state to the retracted state, the second via 22 in the protection door 2 can be blocked. set 1 of the first vias 11 set (Here, the first via 11 is No. 1 set When the protection door 2 transitions from the initial state to the retracted state, the protection door 2 moves from the first position to the second position on the support base 1 accordingly. Another pair By placing the first via 11 at a first position on the support 1 (where, Another pair The first via 11 No. 2 set When the protective door 2 is in the first position, the protective door 2 is in the first position. No. 2 set When the protective door 2 is moved to the second position, the first via 11 of the protective door 2 can be blocked. No. 2 set The first via 11 is exposed when the protective door 2 is retracted. Therefore, when the protective door 2 is in the retracted state, No. 1 set The first via 11 of the protective door 2 communicates with the second via 22 of the protective door 2 to allow exposure. set Both of the first vias 11 allow exposure for pin insertion.

[0052] When the pin abuts against the upper surface 21 of the protection door 2, the protection door 2 can be driven to move, and the movement first moves along the first direction D1 perpendicular to the upper surface 21 of the protection door 2, that is, from top to bottom. The movement of the protection door 2 along the first direction D1 becomes smoother and no jamming phenomenon occurs. Then, the movement direction changes, and the protection door 2 moves along the second direction D1 of the support base 1. setThe N-pole plug bushing and the L-pole plug bushing of the socket move along the distributed second direction D2 until the first via 11 of the socket is exposed. When the protective door 2 transitions from the initial state to the retracted state, the elastic reset member 3 has elastic force due to being compressed by the protective door 2, and after the pin is pulled out from the plug bushing, the elastic reset member 3 is reset by the action of the elastic force, and also drives the protective door 2 to be reset to the initial state.

[0053] 9 and 10 , the socket protection door structure according to the embodiment of the present disclosure further includes a stopper 7, which is disposed on the bottom support 101 of the support 1, and the tip of the stopper 7 is located within the second via 22 of the protection door panel 201 of the protection door 2. When the protection door 2 is tilted to one side by inserting a single pin, the stopper 7 can abut against the wall of the second via 22. For example, the stopper 7 is flat, and in the case of inserting a single pin, when the protective door 2 tilts toward the insertion side, the stopper 7 abuts against the wall of the second via 22 in the protective door 2, and can stop the protective door 2 from further rotating. This prevents the protective door 2 from moving along the second direction D2, and still serves to protect the plug bushing and achieves the function of preventing the insertion of a single pin. In addition, providing the stopper 7 is advantageous for smooth resetting of the tilted protective door 2, and by blocking the line of sight of the elastic reset member 3 with the stopper 7, aesthetics are improved. do.

[0054] 3 is a structural schematic diagram of an exemplary three-pole protective door according to an embodiment of the present disclosure, where A shows the front structure of the protective door 2, B shows the back structure of the protective door 2, and C shows the housing structure of the protective door 2 excluding the protective door panel 201. FIG. 4 is a structural schematic diagram of an exemplary two-pole protective door according to an embodiment of the present disclosure, where the front structure and back structure of the protective door 2 are respectively shown.

[0055] In some feasible embodiments, as shown in Figure 3 or Figure 4, the protective door 2 includes a protective door panel 201 and a housing 202, where the housing 202 is movably connected to the support base 1, the protective door panel 201 is connected to the tip of the housing 202, the upper surface of the protective door panel 201 is the upper surface 21 of the above-mentioned protective door 2, and the protective door panel 201 has a second via 22.

[0056] The protective door panel 201 of the protective door 2 is closer to the jack of the socket than the housing 202 when applied to the socket, and in some examples, the upper surface of the protective door panel 201 The face is , Some Designed to be flat, A portion of the protective door panel 201 may be designed to have a sloped surface. For example, the upper surface of the protective door panel 201 adjacent to the second via 22 may be designed to have a sloped surface, and the other portion may be designed to have a flat surface. As shown in FIG. 3 or 4, when the protective door panel 201 has the second via 22 and the protective door 2 is in the initial state, the second via 22 in the protective door panel 201 is connected to the second via 22 in the support base 1. set In this way, the other portion of the protective door panel 201 is offset from the first via 11. set The first via 11 can be plugged.

[0057] The shape of the second via 22 thereon is determined based on the shape of the plug bushing blocked by the protective door 2, and in some examples, the structure and size of the second via 22 match the structure and size of the corresponding communicating first via 11. For example, if the plug bushing is a two-pole plug bushing, the second via 22 has a linear shape, and its longitudinal direction matches the longitudinal direction of the socket jack, and if the plug bushing is a three-pole plug bushing, the second via 22 has a diagonal linear shape, and its inclination direction matches the inclination direction of the plug bushing.

[0058] In some examples, the housing 202 of the protective door 2 includes a first side, a second side, a third side, and a fourth side connected in sequence from end to end, and these four sides form a first cavity that can accommodate the protective door panel 201. For any two connected sides, there is an angle between them, which may be 90° or less.

[0059] For example, for a protective door 2 corresponding to a two-pole plug bush, the housing 202 may be rectangular, and for a protective door 2 corresponding to a three-pole plug bush, the housing 202 may be rectangular or trapezoidal, etc.

[0060] The protective door panel 201 is adapted to the structure of the housing 202, and the protective door panel 201 is detachably fixed to the top of the housing 202. For example, there is a slot at the top of the housing 202, and there is an insert block at the bottom of the protective door panel 201. The insert block is inserted into the slot to fix the protective door panel 201 to the housing 202.

[0061] In some possible embodiments, as shown in FIG. 1, with reference to FIGS. 3 and 4, the socket protection door structure according to the embodiment of the present disclosure includes two set Further, the external guide shaft 4 is setThe external guide shaft 4 extends along the second direction D2 of the protective door 2. set are respectively disposed outside the side walls of the respective Here, the number of external guide shafts 4 in each set may be one (see FIGS. 3 and 4) or may be plural.

[0062] For example, the external guide shaft 4 is a cylindrical body. set Each of the external guide shafts 4 is positioned at a central position outside the side wall of the housing 202, and in this way, both sides of the protective door 2 on which the external guide shafts 4 are provided are positioned symmetrically, allowing the protective door 2 to move around the external guide shaft 4 as the center of movement.

[0063] As shown in FIG. 5, the support base 1 includes a bottom support portion 101 and a side peripheral portion 102. The bottom support portion 101 has the above-mentioned two set The first via 11(2 set The lower end of the side periphery 102 is connected to the bottom support 101, and two vias 11 extending along the second direction D2 of the side periphery 102 are provided. set The guide grooves 103 are provided on the side walls of the external guide shaft 4, and the guide grooves 103 accommodate the external guide shaft 4 and guide the movement of the external guide shaft 4 in the first direction D1 and the second direction D2.

[0064] In the embodiment of the present disclosure, the bottom support portion 101 of the support base 1 is not only used to support the side periphery 102, but also to support the plug bush portion of the socket, so that the area of ​​the bottom support portion 101 of the support base 1 can be larger than the area of ​​the side periphery 102. For example, when the socket protection door structure is used for a five-hole socket, the bottom support portion 101 of the support base 1 can be designed to simultaneously support the two-pole plug bush and the three-pole plug bush of the socket, and the side periphery 102 can be doubled to respectively correspond to the two-pole plug bush and the three-pole plug bush. set (One bottom support part 101 can have two set The side periphery 102 is supported.

[0065] For example, the bottom support 101 has a protective door assembly area, and the side periphery 102 is disposed in the protective door assembly area. The side periphery 102 includes a first side periphery segment, a second side periphery segment, a third side periphery segment, and a fourth side periphery segment, which are connected end to end in sequence, and these four side periphery segments are connected to each other to form a second cavity, which is used to accommodate the protective door 2 and the elastic reset member 3. Any two side periphery segments having a connecting relationship can be used as a second cavity. set There is an angle between the peripheral segments, for example, the angle may be 90°, and each peripheral segment may be a straight plate segment, a bent-line plate segment, or a plate segment with a certain degree of curvature.

[0066] The area of ​​the second cavity surrounded by the side periphery 102 is larger than the area of ​​the protective door 2. As shown in FIG. 2, the second cavity of the side periphery 102 further includes a protective door initial assembly area 1021 and a protective door evacuation area 1022. set At the same time, the first via 11 is also located in the initial assembly area 1021. When the protective door 2 is in the initial state, the protective door 2 is located in the protective door initial assembly area 1021. When the protective door 2 transitions from the initial state to the evacuation state, a part of the protective door 2 moves to the protective door evacuation area 1022, and the other part of the protective door 2 remains located in the protective door initial assembly area 1021. 1 set First via 1 1 is , and is exposed by exiting protective door 2.

[0067] The two side walls of the side periphery 102 extending along the second direction D2 each have a guide groove 103, and the guide groove 103 accommodates the external guide shaft 4 and guides the movement of the external guide shaft 4 in the first direction D1 and the second direction D2. set The guide grooves 103 are formed in the side peripheral segments. Two sets of guide grooves 103 are provided. Here, the number of guide grooves 103 in each set may be one or more. .

[0068] 2 set The guide groove 103 is set The external guide shaft 4 passes through the corresponding guide groove 103, and the guide groove 103 guides the movement of the external guide shaft 4 in the first direction D1 and the second direction D2. That is, the guide groove 103 includes at least groove cavities distributed along the first direction D1 and groove cavities distributed along the second direction D2.

[0069] For example, as shown in FIG. 6, the guide groove 103 includes a guide segment 1031, a regulating segment 1032, a first guide segment 1033, and a second guide segment 1034 that are connected in series, and the guide segment 1031, the regulating segment 1032, and the first guide segment 1033 all extend along a first direction D1, and the second guide segment 1034 extends along a second direction D2.

[0070] The guide segment 1031 is used to guide the external guide shaft 4 into the regulating segment 1032, the regulating segment 1032 is used to regulating the external guide shaft 4 within the first guide segment 1033, the first guide segment 1033 is used to guide the movement of the external guide shaft 4 in the first direction D1, and the second guide segment 1034 is used to guide the movement of the external guide shaft 4 in the second direction D2.

[0071] In application, the external guide shaft 4 is assembled under the guidance of the guide segment 1031 and enters the first guide segment 1033 through the regulating segment 1032. When the protective door 2 is in its initial state, the external guide shaft 4 is regulated by the regulating segment 1032 and is always located within the first guide segment 1033. When the protective door 2 is driven by the pin to move, it enters the second guide segment 1034 through the first guide segment 1033, realizing the movement of the protective door 2 in the first direction D1 and the second direction D2.

[0072] By using the guide groove 103, the external guide shaft 4 can not only be moved sequentially along the first guide segment 1033 and the second guide segment 1034, but also the external guide shaft 4 can be moved sequentially along the second guide segment 1034 and the first guide segment 1033.

[0073] The above guide segment 1031, regulating segment 1032, first guide segment 1033 and second guide segment 1034 all have two side walls facing each other at a distance from each other, and these two side walls originate from the side walls of the side periphery 102 located on both sides of the guide groove 103 in the support base 1.

[0074] In some examples, as shown in FIG. 6, the second guide segment 1034 includes a first side wall 10341 and a second side wall 10342 spaced apart, wherein the first side wall 10341 extends along a first direction D1 (i.e., the first side wall 10341 is arranged vertically along the up-down direction), the second side wall 10342 is arranged at an angle and extends along a second direction D2 (i.e., the second side wall 10342 is arranged at an angle along the left-right direction), and the distance between the tip of the second side wall 10342 and the first side wall 10341 is smaller than the distance between the lower end of the second side wall 10342 and the first side wall 10341.

[0075] In an embodiment of the present disclosure, the second side wall 10342 may be located to the right of the first side wall 10341, in which case the protective door 2 only needs to move to the right when moving to the retracted state, and the second side wall 10342 may be located to the left of the first side wall 10341, in which case the protective door 2 only needs to move to the left when moving to the retracted state.

[0076] When the protective door 2 transitions from the initial state to the retracted state, or is reset from the retracted state to the initial state, the second guide segment 1034 allows the protective door 2 to move in the second direction D2, and during this process, the second side wall 10342 of the second guide segment 1034 can guide the movement of the external guide shaft 4 by contacting the external guide shaft 4, thereby promoting the movement of the protective door 2 and making the movement of the protective door 2 smoother.

[0077] The first guide segment 1033 extends in the vertical direction, and the second guide segment 1034 extends in the horizontal direction, thereby forming an L-shaped guide segment, which restricts the external guide shaft 4, allowing the external guide shaft 4 to effectively incline and slide within the L-shaped guide segment. As a result, not only is the sliding stroke of the protective door 2 reduced and the frictional resistance reduced, but the requirements for the insertion operation by the user are also reduced, the adaptability required for the insertion operation is broader, and the plug can be inserted easily, providing a comfortable insertion feel and avoiding the feeling of sticking in the user's experience.

[0078] In addition, the cooperative drive of the external guide shaft 4 and the L-shaped guide segment can avoid the technical problem of wear on the driving surface caused by the plug, and reduces the requirements for the material properties of the protective door 2, which is advantageous for cost reduction.

[0079] Referring to the socket protection door structure according to an embodiment of the present disclosure, the process of normally opening the protection door 2 will be exemplarily described.

[0080] As shown in Figures 5 to 7, when the protection door 2 is opened normally, two pins M need to be inserted into the N-pole jack and the L-pole jack, respectively. With the thrust of the two pins M, the external guide shaft 4 of the protection door 2 first moves along the first direction D1 in the first guide segment 1033, until the external guide shaft 4 enters the second guide segment 1034 and moves along the second direction D2. The protection door 2 moves to the waiting state in this way. setThe first vias 11 are exposed, and the two pins M are inserted into the corresponding first vias 11 and finally into the corresponding plug bushings (see FIG. 8). As shown in FIG. 8, in the retracted state, the side wall of the housing 202 of the protective door 2 is attached to the side wall of one of the pins M, and one side wall of the second vias 22 of the protective door 2 is attached to the side wall of the other pin M.

[0081] Regarding the reset process of the protective door 2, first, the two pins M are withdrawn from the plug bush, and then the compressed elastic reset member 3 drives the protective door 2 to reset, so that the outer guide shaft 4 first slides along the second guide segment 1034 until it enters the first guide segment 1033, and is restricted by the restricting segment 1032, finally resetting the protective door 2 to the initial state. In the initial state, the elastic reset member 3 presses the protective door 2 so that the upper surface 21 of the protective door 2 is in close contact with the jack.

[0082] In the socket protection door structure according to the embodiment of the present disclosure, the sliding of the protection door 2 along the first direction D1 and the second direction D2 occupies a small space (small volume) and has a short sliding stroke, which is advantageous for simplifying the socket protection door structure, reducing the number of parts (reducing materials), realizing a reduction in the number of components, simplifying the assembly process of the protection door 2, and reducing costs. In the related art, a five-hole socket includes at least 14 parts, but the five-hole socket using the socket protection door structure according to the embodiment of the present disclosure includes only nine parts, which has the advantages of more product functions, fewer parts products, and easier automated production.

[0083] In some examples, the angle between the second side wall 10342 and the first direction D1 is greater than or equal to 17° and less than or equal to 90°, for example, 25°, 27°, 30°, 35°, etc., and within this angle range, the movement of the protective door 2 can be made smoother.

[0084] In some examples, the length of the second side wall 10342 is greater than 0 and less than 2.6 mm, for example, 1 mm, 1.5 mm, 2 mm, 2.5 mm, etc., and the length of the second side wall 10342 actually represents the sliding stroke of the protective door 2, and by limiting the sliding stroke as above, the movement of the protective door 2 can be made smoother.

[0085] In particular, by making the angle between the second side wall 10342 and the first direction D1 greater than or equal to 27° and less than or equal to 90°, and making the sliding stroke of the protective door 2 less than or equal to 2.6 mm, the sliding of the protective door 2 can be made smoother and the feeling of catching can be avoided. This is advantageous for increasing the service life of the protective door 2 under such conditions, and can ensure that the sliding reset life of the protective door 2 reaches at least 40,000 times, exceeding the national standard.

[0086] The range of the inclination angle of the second side wall 10342 of the second guide segment 1034 can be determined as follows.

[0087] When the protective door 2 returns to its original position, the outer guide shaft 4 first slides along the second guide segment 1034, that is, the outer guide shaft 4 and the second side wall 10342 of the second guide segment 1034 come into contact with each other to generate friction. The socket support 1 is usually made of polycarbonate in accordance with the national standards of the People's Republic of China, and the friction coefficient μ of polycarbonate is μ=0.25~0.35, which is calculated by the following formula: F elastic force sinθ-μF pressure >0, the elastic force overcomes the friction force, and the protective door 2 can be reset. According to the formula of Newton's third law, the acting force is equal to the reaction force, that is, F pressure =F elastic force cos θ, and by calculation, the angle θ between the second side wall 10342 and the first direction D1 is greater than 17°, that is, 17° is the boundary value.

[0088] Considering the resistance caused by the unevenness of the inclined surface of the protective door 2 during long-term sliding friction, the angle between the second side wall 10342 and the first direction D1 can be increased, for example, 25°, 27°, 30°, 35°, etc., which can promote more effective resetting of the protective door 2 during long-term sliding.

[0089] In an embodiment of the present disclosure, the lower end of the side wall of the side periphery 102 on which the second guide segment 1034 is provided may be directly connected to the bottom support 101, or as shown in FIG. 6, the lower end of the side wall of the side periphery 102 on which the second guide segment 1034 is provided may be suspended, that is, the guide groove 103 and the bottom support 101 are offset in the third direction D3, where the third direction D3 is a direction perpendicular to the second direction D2, where the side wall of the side periphery 102 on which the second guide segment 1034 is provided is close to the outside, its bottom is suspended, and the bottom support 101 is closer to the inside.

[0090] The above design of the bottom of the second guide segment 1034 being suspended can effectively simplify the mold structure, reduce the manufacturing difficulty, and increase the stability of mold production.

[0091] Regarding the regulating segment 1032 of the guide groove 103, in some possible embodiments, as shown in Fig. 6, the regulating segment 1032 includes a third side wall 10321 and a fourth side wall 10322 arranged symmetrically, and there is a gap between the third side wall 10321 and the fourth side wall 10322, which is the regulating segment 1032. The distance between the third side wall 10321 and the fourth side wall 10322 gradually increases along a direction approaching the first guide segment 1033, and the minimum distance between the third side wall 10321 and the fourth side wall 10322 is smaller than the outer diameter of the external guide shaft 4.

[0092] For example, the third side wall 10321 and the fourth side wall 10322 may have the same shape, for example, both being arc-shaped walls, wedge walls, etc. For example, the third side wall 10321 and the fourth side wall 10322 may be symmetrically arranged arc-shaped walls, and the distance between the third side wall 10321 and the fourth side wall 10322 gradually decreases along the direction approaching the first guide segment 1033 until it reaches a minimum, and then gradually increases from the minimum.

[0093] In this way, after the external guide shaft 4 is forced into the regulating segment 1032 by an external force, the external guide shaft 4 is restricted by the minimum distance between the third side wall 10321 and the fourth side wall 10322 and cannot freely leave the regulating segment 1032, thereby realizing the effective restriction of the external guide shaft 4 by the regulating segment 1032, which is not only beneficial to maintaining the initial state of the protective door 2 but also beneficial to improving the assembly efficiency of the protective door 2.

[0094] Regarding the first guide segment 1033 of the guide groove 103, in some feasible embodiments, as shown in FIG. 6, the first guide segment 1033 includes a fifth side wall 10331 and a sixth side wall 10332 that are parallel and opposite to each other, that is, the distance between the fifth side wall 10331 and the sixth side wall 10332 is always the same, and the fifth side wall 10331 and the sixth side wall 10332 both extend along the first direction D1, so that the external guide shaft 4 moves along the first direction D1 in the first guide segment 1033.

[0095] Regarding the guide segment 1031 of the guide groove 103, in some possible embodiments, as shown in FIG. 6, the guide segment 1031 includes a seventh side wall 10311 and an eighth side wall 10312 arranged symmetrically, and there is a gap between the seventh side wall 10311 and the eighth side wall 10312, to form the guide segment 1031. In particular, the seventh side wall 10311 and the eighth side wall 10312 are both inclined, the distance between the tip of the seventh side wall 10311 and the tip of the eighth side wall 10312 is greater than the distance between the bottom end of the seventh side wall 10311 and the bottom end of the eighth side wall 10312, and the distance between the tip of the seventh side wall 10311 and the tip of the eighth side wall 10312 is greater than the outer diameter of the external guide shaft 4, so that the external guide shaft 4 can easily enter the guide segment 1031 to guide the assembly of the guide protection door 2 to the support base 1.

[0096] In the socket protection door structure according to an embodiment of the present disclosure, the seventh side wall 10311, the third side wall 10321, the fifth side wall 10331, and the first side wall 10341 are sequentially connected and integrally formed, and the eighth side wall 10312, the fourth side wall 10322, the sixth side wall 10332, and the second side wall 10342 are sequentially connected and integrally formed.

[0097] In some possible embodiments, as shown in FIG. 5, the socket protection door structure is composed of two symmetrically arranged set The guide block 5 further includes set The guide block 5 is disposed on the upper surface of the bottom support 101, and set The distribution direction of the guide blocks 5 is along the third direction D3. Here, the number of guide blocks 5 in each set of guide blocks 5 may be one (see FIG. 5, for example) or may be plural.

[0098] The guide block 5 has a guide surface 51, which is inclined and extends along the second direction D2, and is used to contact the protective door 2 so as to guide the movement of the protective door 2. Here, the movement of the protective door 2 includes the movement of the protective door 2 in the second direction D2 under the driving of two pins, and the tilting movement of the protective door 2 under the driving of one pin.

[0099] In some examples, the guide block 5 contacts the bottom of the side wall of the protective door 2, i.e., the bottom wall of the housing 202 of the protective door 2. In other examples, the guide block 5 contacts the bottom of the side panel of the protective door 2, i.e., the bottom wall of the protective door panel 201 of the protective door 2. The position of the guide block 5 on the bottom support portion 101 can be adaptively adjusted depending on what the guide block 5 contacts.

[0100] For example, the guide block 5 has a plate-like structure, such as a triangular plate, and either corner of the guide block 5 is formed in a smoothly transitioning arc shape so that the surface on which one side of the triangular plate-like guide block 5 is located is fixed to the upper surface of the bottom support part 101, and the surface on which the other side is located becomes the guide surface 51.

[0101] For example, when the guide block 5 contacts the bottom of the side wall of the protective door 2, when the protective door 2 moves along the second direction D2 under the driving of the two pins, the housing 202 of the protective door 2 contacts the guide surface 51. In this way, the guide surface 51 guides the movement of the protective door 2 in the second direction D2, and by cooperating with the movement of the external guide shaft 4 in the guide groove 103, the smoothness of the movement of the protective door 2 is further improved, and the protective door 2 can be moved more easily to the sheltered state.

[0102] Furthermore, by bringing the housing 202 of the protective door 2 into contact with the guide surface 51 of the guide block 5 early before the external guide shaft 4 enters the second guide segment 1034 from the first guide segment 1033, it is advantageous to improving the service life of the protective door 2. In such a case, by making the inclination angle of the second side wall 10342 of the second guide segment 1034 equal to or greater than the inclination angle of the guide surface 51, it is possible to ensure that the housing 202 of the protective door 2 comes into contact with the guide surface 51 early, and that the protective door 2 opens smoothly.

[0103] When the protective door 2 returns to its original position, the external guide shaft 4 is brought into contact with the second side wall 10342 of the second guide segment 1034, thereby guiding the return movement of the external guide shaft 4 in the second direction D2, and the guide surface 51 of the guide block 5 is no longer in contact with the housing 202 of the protective door 2.

[0104] For example, when the guide block 5 contacts the bottom of the side wall of the protective door 2, when the protective door 2 tilts under the driving of one pin, that is, when the driven side of the protective door 2 tilts downward, the bottom of the housing 202 of the protective door 2 contacts the guide surface 51, and the guide surface 51 guides the tilting movement of the protective door 2. Specifically, the guide surface 51 acts as a force receiving point to perform a bending movement, making the movement of the protective door 2 smoother.

[0105] In some possible embodiments, as shown in FIG. 5 or FIG. 6, the socket protection door structure is composed of two symmetrically arranged set The guide block 5 further includes set The guide block 5 is disposed on the upper surface of the bottom support 101, and set The distribution direction of the guide blocks 5 is along the third direction D3. The guide blocks 5 have guide surfaces 51, which are inclined and extend along the second direction D2. As shown in FIG. 3 or FIG. 4, the socket protection door structure according to the embodiment of the present disclosure has two set Further, the internal guide shaft 9 includes set The inner guide shaft 9 is arranged in the protective door 2, setThe internal guide shaft 9 of set 9, the inner guide shaft 9 is used to contact the guide surface 51 of the corresponding guide block 5 to guide the movement of the protection door 2. Here, the movement of the protection door 2 includes the movement of the protection door 2 in the second direction D2 under the driving of two pins, and the tilting movement of the protection door 2 under the driving of one pin. Here, the number of internal guide shafts 9 in each set of internal guide shafts 9 may be one (see, for example, FIG. 3 or FIG. 4) or may be plural.

[0106] The internal guide shaft 9 may be in the shape of an arc column or a cylinder, and the longitudinal direction of the internal guide shaft 9 is the same as the longitudinal direction of the external guide shaft 4, and the circumferential direction of the internal guide shaft 9 is the same as the circumferential direction of the external guide shaft 4. In this way, the internal guide shaft 9 moves more smoothly on the guide surface 51 of the guide block 5.

[0107] 3, the protective door 2 includes a protective door panel 201 and a housing 202, the protective door panel 201 having the above-mentioned upper surface 21, the protective door panel 201 being connected to the tip of the housing 202, and the housing 202 being movably connected to the support base 1. The internal guide shaft 9 is disposed inside two side walls of the housing 202 extending along the second direction D2.

[0108] By positioning the internal guide shaft 9 inside the two side walls extending along the second direction of the housing 202, the internal guide shaft 9 can make efficient use of the internal space of the protective door 2, which is advantageous for making the structure of the protective door 2 smaller and lighter.

[0109] The external guide shaft 4 and the internal guide shaft 9 are respectively arranged outside and inside the side wall of the housing 202, and the external guide shaft 4 and the internal guide shaft 9 arranged on the same side face each other in a one-to-one relationship. This structure is not only advantageous for manufacturing, but also for improving the strength of the protective door 2.

[0110] For example, when the protective door 2 moves along the second direction D2 under the drive of the two pins, the internal guide shaft 9 comes into contact with the guide surface 51, and in this way, the guide surface 51 guides the movement of the protective door 2 in the second direction D2, and by cooperating with the movement of the external guide shaft 4 in the guide groove 103, the smoothness of the movement of the protective door 2 is further improved, and the protective door 2 can be moved more easily to the retracted state (not shown).

[0111] Furthermore, by having the internal guide shaft 9 come into contact with the guide surface 51 of the guide block 5 early before the external guide shaft 4 enters the second guide segment 1034 from the first guide segment 1033, it is advantageous to improving the service life of the protective door 2. In this case, by making the inclination angle of the second side wall 10342 of the second guide segment 1034 equal to or greater than the inclination angle of the guide surface 51, the internal guide shaft 9 comes into contact with the guide surface 51 early, ensuring smooth opening of the protective door 2.

[0112] When the protective door 2 returns to its original position, the external guide shaft 4 is brought into contact with the second side wall 10342 of the second guide segment 1034, thereby guiding the return movement of the external guide shaft 4 in the second direction D2, and the guide surface 51 of the guide block 5 is no longer in contact with the internal guide shaft 9.

[0113] For example, as shown in FIG. 9, when the protection door 2 tilts when driven by one pin, that is, when the driven side of the protection door 2 tilts downward, the internal guide shaft 9 contacts the guide surface 51, and the guide surface 51 guides the tilting movement of the protection door 2. Specifically, the guide surface 51 acts as a force receiving point to perform a bending movement, thereby making the movement of the protection door 2 smoother.

[0114] In this way, the cooperation between the internal guide shaft 9 and the guide block 5 promotes the movement of the protection door 2 from the first direction D1 to the second direction D2, and the cooperation between the external guide shaft 4 and the second guide segment 1034 promotes the return movement of the protection door 2 from the second direction D2 to the first direction D1, which is advantageous to improving the service life of the protection door 2. In addition, the movement of the protection door 2 is promoted by the internal guide shaft 9 contacting the guide surface 5, and this contact method has a smaller contact area and correspondingly smaller friction force, which is advantageous to improving the smoothness of the movement of the protection door 2 and improving the user experience.

[0115] In particular, due to the offset arrangement of the guide groove 103 and the bottom support part 101, the force receiving point when the protective door 2 moves to the retracted state is tilted by the bottom support part 101 of the support base 1, which results in dispersing the force received by the external guide shaft 4, reducing the requirements for the structural rigidity of the protective door 2, making it easier for the external guide shaft 4 and the guide groove 103 to cooperate, and making deformation less likely to occur, which is advantageous in improving the service life of the socket protective door structure.

[0116] In addition, this method of shifting the force receiving point to the bottom support part 101 of the support base 1 is also advantageous for reducing the thickness of the protective door 2. On the premise that the plug bushing that contacts the plug meets the requirements of the national standard H1 of the People's Republic of China, when the space created by the reduction in the thickness of the protective door 2 is correspondingly transferred to the socket, the maximum thickness of the decorative protective door panel 201 of the socket will be 4 mm or less.

[0117] In some possible embodiments, as shown in FIG. 3, the housing 202 of the protective door 2 includes a side frame 2021 and a panel rack 2022, the panel rack 2022 is disposed inside the side frame 2021, the bottom wall of the panel rack 2022 has a via with the same structure as the second via 22, and the bottom surface of the panel rack 2022 has a via 22. set There is a relief groove of 2023, set The relief groove 2023 is 2 setThe relief grooves 2023 correspond one-to-one to the guide blocks 5, and accommodate at least the tops of the guide blocks 5 when the protection door 2 moves along the second direction D2.

[0118] The clearance groove 2023 is provided on the surface of the panel rack 2022 facing the guide block 5, and the design of the clearance groove 2023 is advantageous for reducing the thickness of the protective door 2 and also for reducing the thickness of the socket, for example, by making the thickness of the outer protective door panel 201 of the socket ≦4 mm, which also reduces the manufacturing cost of the socket.

[0119] In some examples, when the protection door 2 moves along the second direction D2, the undercut groove 2023 can accommodate the top of the guide block 5 (because the top of the guide block 5 corresponds to the maximum height of the guide block 5), and further, the undercut groove 2023 can accommodate the entire guide block 5. In this way, by making the structure of the undercut groove 2023 similar to the structure of the guide block 5, the guide block 5 can be properly fitted into the undercut groove 2023.

[0120] In some examples, before the outer guide shaft 4 of the protective door 2 enters the second guide segment 1034, the inner guide shaft 9 first comes into contact with the guide surface 51 of the guide block 5, causing the inner guide shaft 9 to move in the second direction D2 along the guide surface 51 and promoting the movement of the protective door 2. Furthermore, during this process, at least a portion of the top of the guide block 5 enters the undercut groove 2023.

[0121] In the embodiment of the present disclosure, the elastic reset member 3 is disposed between the support base and the protective door 2, and when the protective door 2 is in the initial state of movement, the elastic reset member 3 is in a naturally extended state, and when the protective door 2 is in the retracted state, the elastic reset member 3 is compressed to an elastically compressed state by the moving protective door 2. In this way, when the protective door 2 in the retracted state is no longer subjected to an external force, the elastic reset member 3 performs a reset and resets the protective door 2 to its initial state.

[0122] 3, the socket protection door structure according to the embodiment of the present disclosure further includes a fixing block 6, which is disposed on the bottom surface of the protection door 2, specifically on the bottom surface of the panel rack 2022 of the protection door 2. The fixing block 6 is connected to the elastic reset member 3, and the connection method between the two, for example, maintains a stable assembly relationship between the fixing block 6 and the elastic reset member 3, allowing the protection door 2 and the elastic reset member 3 to be assembled to the support base 1, thereby realizing assembly stability and avoiding the problem of the protection door 2 coming off the elastic reset member 3 during assembly, which reduces assembly efficiency.

[0123] In some examples, the fixed block 6 is movably connected to the elastic reset member 3, i.e., the elastic reset member 3 is not only stably mounted to the fixed block 6 but is also able to move axially to some extent along the fixed block 6.

[0124] For example, the elastic reset member 3 is a compression spring, and the tip of the elastic reset member 3 is fitted to the outside of the fixed block 6, and the two are loosely fitted and relatively fixed by frictional force.

[0125] As an example, the fixed block 6 is cylindrical to fit the compression spring, and the tight fit between the fixed block 6 and the compression spring allows the elastic reset member 3 to be fixed to the fixed block 6 by the friction force between the two, which is advantageous not only for the fixed connection between the two but also for the removal of the two.

[0126] As another example, the fixed block 6 includes a cylindrical segment and a conical segment located at the lower end of the cylindrical segment, and the conical segment is intended to facilitate fitting of the compression spring into the cylindrical segment. The tight fit between the cylindrical segment and the compression spring allows the frictional force between the two to fix the elastic reset member 3 to the cylindrical segment of the fixed block 6.

[0127] In order to reduce the weight of the protective door 2, the fixed block 6 is provided with a number of notches, which are uniformly arranged along the circumferential direction of the fixed block 6, and not only do not affect the clearance fit between the fixed block 6 and the compression spring, but also achieve the purpose of reducing the weight.

[0128] The elastic reset member 3 is fixed to a fixed block 6 arranged on the protective door 2, the longitudinal direction of the elastic reset member 3 is along the first direction D1, and the protective door 2 equipped with the elastic reset member 3 is mounted on the support base 1. In this way, when the protective door 2 is mounted on the support base 1, the elastic reset member 3 assumes a natural stretched state, and when the protective door 2 is attached to the support base 1, no repulsive force is generated due to compression of the elastic reset member 3, so that the problem of reduced attachment efficiency caused by the elastic reset member 3 being ejected can be avoided.

[0129] In the embodiment of the present disclosure, the fixed block 6 is positioned at the center of the bottom surface of the protection door 2, in this way the back of the protection door 2 is supported by the elastic reset member 3 supported vertically (here, the first direction D1 is defined as the vertical direction), and can maintain a horizontal state in the initial state. In the case of a single pin insertion, the protection door 2 can proceed to a warping movement, effectively solving the problem of the protection door 2 not sliding smoothly due to distortion, and the protection door 2 can be rotated at multiple angles and reset normally.

[0130] 1 and 10, the support base 1, specifically the bottom support part 101 of the support base 1, has a restricting groove 104, which accommodates the lower end of the elastic resetting member 3 and allows the elastic resetting member 3 to move correspondingly with the moving protection door 2. In this way, even if an offset occurs in the elastic resetting member 3 during the movement of the protection door 2, the elastic resetting member 3 will not fall off due to the offset transition.

[0131] Illustratively, as shown in FIG. 10, the regulating groove 104 includes a first groove wall 1041 and a second groove wall 1042 that are symmetrically arranged, and the first groove wall 1041 and the second groove wall 1042 are distributed along the second direction D2. That is, the first groove wall 1041 and the second groove wall 1042 are arranged in a 2 set The first vias 11 are distributed in the direction in which they are distributed.

[0132] At least one of the first groove wall 1041 and the second groove wall 1042 is inclined and extends along the second direction D2 so as to accommodate the elastic reset member 3 that moves along with the protective door 2. In some examples, the first groove wall 1041 and the second groove wall 1042 have the same structure, are both inclined, and have opposite inclination directions, and at the same time, both the first groove wall 1041 and the second groove wall 1042 extend along the second direction D2.

[0133] Taking the first groove wall 1041 as an example, the angle between the first groove wall 1041 and the first direction D1 is set to 25° to 35°, for example 30°, and the inclination angle of the first groove wall 1041 is set slightly larger than the offset displacement of the elastic reset member 3. Therefore, when the elastic reset member 3 is subjected to a force and is twisted and deformed, the first groove wall 1041 or the second groove wall 1042 can support the twisted and deformed elastic reset member 3, and can smoothly support the elastic reset member 3 in accordance with the deformation form of the elastic reset member 3, thereby reducing fatigue and being advantageous for improving the service life of the elastic reset member 3.

[0134] In addition to the first groove wall 1041 and the second groove wall 1042, the regulating groove 104 further includes a third groove wall and a fourth groove wall arranged symmetrically, and the first groove wall 1041, the third groove wall, the second groove wall 1042 and the fourth groove wall are connected sequentially from end to end to form the regulating groove 104, and the third groove wall and the fourth groove wall are also arranged at an incline so as to fit into the first groove wall 1041 and the second groove wall 1042.

[0135] For example, the first groove wall 1041 and the second groove wall 1042 are formed in an arc shape along their width direction (i.e., a direction perpendicular to the top and bottom ends), thereby forming the first groove wall 1041 and the second groove wall 1042 into arc-shaped walls. Correspondingly, the third groove wall and the fourth groove wall are formed in a linear planar structure along their width direction, thereby forming the third groove wall and the fourth groove wall into planar walls.

[0136] Therefore, the width of the restriction groove 104 according to the embodiment of the present disclosure gradually decreases from its tip to its bottom end, and the maximum width of the restriction groove 104 is greater than the diameter of the elastic reset member 3, which is determined by the offset displacement of the elastic reset member 3. The minimum width of the restriction groove 104 is smaller than the diameter of the elastic reset member 3, that is, the bottom end of the restriction groove 104 is designed in the shape of a circular hole to accommodate and restrict the elastic reset member 3, thereby restricting the elastic reset member 3 by the restriction groove 104. By restricting the elastic reset member 3 within the restriction groove 104 configured in this way, it is possible to effectively prevent the elastic reset member 3 from falling off due to the offset transition during the offset process.

[0137] In some feasible embodiments, as shown in Figures 9 and 10, the socket protective door structure according to the embodiment of the present disclosure further includes a stopper 7, which is arranged on the bottom support portion 101 of the support base 1, and the tip of the stopper 7 is located in the second via 22 of the protective door panel 201 of the protective door 2, so that when the protective door 2 is tilted to one side by inserting a single pin, the stopper 7 can abut against the wall of the second via 22.

[0138] For example, the stopper 7 is flat, and in the case of inserting a single pin, when the protective door 2 tilts toward the insertion side, the stopper 7 abuts against the wall of the second via 22 in the protective door 2, preventing the protective door 2 from further rotating. This prevents the protective door 2 from moving along the second direction D2, still protecting the plug bushing and realizing the function of preventing the insertion of a single pin. Incidentally, providing the stopper 7 is advantageous for smooth resetting of the tilted protective door 2, and by blocking the view of the elastic reset member 3 from the outside, the stopper 7 improves the aesthetics.

[0139] In order to improve the reliability of the socket protection door structure in preventing the insertion of a single pin, as shown in FIG. 9, the socket protection door structure according to the embodiment of the present disclosure further includes two sets of first stopper blocks 12 and two sets of second stopper blocks 13, the two sets of first stopper blocks 12 correspond one-to-one to the two sets of second stopper blocks 13, and the two sets of first stopper blocks 12 are respectively disposed on both sides of the protection door 2 extending along the third direction D3, that is, the two sets of first stopper blocks 12 are distributed along the distribution direction of the N-pole plug bush and the L-pole plug bush (that is, the distribution direction of the two sets of first stopper blocks 12 is 2 set The two sets of second stopper blocks 13 are arranged in the same direction as the distribution direction of the first vias 11. set The third direction D3 is disposed on the side wall of the first via 11. When the protective door 2 is tilted to one side by inserting a single pin, the first stopper block 12 tilted toward the first via 11 cooperates with the corresponding second stopper block 13 to achieve the stop. Here, the third direction D3 is perpendicular to the second direction D2.

[0140] In the embodiment of the present disclosure, the restriction groove 104 for accommodating the elastic reset member 3 is formed by arranging two vias 11 so that one side wall of the first via 11 is close to the restriction groove 104. setThe other side wall of the first via 11 faces the first stopper wall and is referred to as the second stopper wall. The second stopper block 13 may be disposed on the first stopper wall, and accordingly, the second stopper block 13 cooperates with the inner side of the first stopper block 12 adjacent to the restriction groove 104 to realize a stop.

[0141] In the embodiment of the present disclosure, one side wall of the first via 11 is adjacent to the intermediate position of the support base 1 and is referred to herein as a first stopper wall, and the other side wall of the first via 11 is opposite to the first stopper wall and is referred to herein as a second stopper wall. The second stopper block 13 may be disposed on the first stopper wall, and correspondingly, the second stopper block 13 cooperates with the inner side of the first stopper block 12 adjacent to the intermediate position of the protective door 2 to realize a stop.

[0142] The second stopper block 13 may be arranged on the second stopper wall, and correspondingly, the second stopper block 13 cooperates with the outside of the first stopper block 12 away from the intermediate position of the protective door 2 to achieve the stopper, and in either case, the first stopper block 12 and the second stopper block 13 cooperate to achieve the stopper.

[0143] As shown in Figure 9, when a single pin is inserted into one surface of the protective door 2, the protective door 2 moves at an angle, and the first stopper block 12, which is inclined toward the first via 11, cooperates with the second stopper block 13 on the side wall of the first via 11 to achieve a stop. In this way, the first stopper block 12 can be stopped at the first via 11 and can further stop the inclined protective door 2. The protective door 2 cannot move along the second direction D2 and still play a role in protecting the plug bush. The single pin cannot enter the first via 11, and the function of preventing the insertion of a single pin is achieved.

[0144] FIG. 3 is a structural schematic diagram of an exemplary three-pole protective door according to an embodiment of the present disclosure, where A shows the front structure of the protective door, B shows the back structure of the protective door, and C shows the housing structure excluding the protective door panel. FIG. 4 is a structural schematic diagram of an exemplary two-pole protective door according to an embodiment of the present disclosure, where the front structure and back structure of the protective door are respectively shown.

[0145] In some possible embodiments, as shown in FIG. 3 or FIG. 4, the protective door 2 includes a protective door panel 201 and a housing 202, the housing 202 is movably connected to the support base 1, the protective door panel 201 is connected to the tip of the housing 202, the protective door panel 201 has an upper surface 21 and a second via 22, the second via 22 is exposed set 1 of the first vias 11 set This is for communicating in response to the above.

[0146] The two sets of first stopper blocks 12 are two sets of stopper blocks 12 extending along the third direction D3 of the housing 202. set The first stopper blocks 12 are disposed on both sides of the housing 202 extending along the third direction D3, i.e., on the left and right sides of the housing 202, so that in the case of inserting a single pin, the left side of the protective door 2 is inclined so that the left first stopper block 12 is positioned in the left first via 11, or the right side of the protective door 2 is inclined so that the right first stopper block 12 is positioned in the right first via 11. In this way, the first stopper blocks 12 positioned on the left or right side of the housing 202 of the protective door 2 cooperate with the second stopper blocks 13 in the corresponding first via 11 to realize a stop, and further realize a stop for the protective door 2 inclined to one side, thereby realizing the effect of preventing the insertion of a single pin.

[0147] In an embodiment of the present disclosure, each set of first stopper blocks 12 may include one first stopper block 12, or may include multiple first stopper blocks 12, for example, two or three, and correspondingly, the number of second stopper blocks 13 is the same as the number of first stopper blocks 12 and cooperates with each other in a one-to-one correspondence to realize a stopper.

[0149] As shown in FIG. 3 or FIG. 4, when the protective door panel 201 has the second via 22 and the protective door 2 is in the initial state, the second via 22 in the protective door panel 201 is connected to the second via 22 in the support base 1. set In this way, the other portion of the protective door panel 201 is offset from the first via 11. set The first via 11 of the plug bushing can be blocked. The shape of the second via 22 thereon is determined based on the shape of the plug bushing blocked in the protective door 2. For example, if the plug bushing is a two-pole plug bushing, the second via 22 has a linear shape, and its longitudinal direction coincides with the longitudinal direction of the socket jack. If the plug bushing is a three-pole plug bushing, the second via 22 has an oblique linear shape, and its inclination direction coincides with the inclination direction of the plug bushing.

[0150] In some possible embodiments, as shown in FIG. 11, the housing 202 has two opposingly arranged set The first side panel 20211 and the second side panel 20212 are arranged opposite each other. set and a second side plate 20212, wherein both ends of the first side plate 20211 are vertically connected to both ends of the second side plate 20212, respectively, and the second side plate 20212 extends along a third direction D3, and a first stopper block 12 is disposed at the lower end of the second side plate 20212, and a stopper groove 20213 is located between the first stopper block 12 and the first side plate 20211, and the stopper groove 20213 is used to accommodate the second stopper block 13.

[0151] The second stopper blocks 13 are configured to be able to enter at least the stopper grooves 20213 to cooperate with each other to achieve a stop. For example, the second stopper blocks 13 may be from the side walls of the first vias 11 or may be independently connected to the side walls of the first vias 11, and the second stopper blocks 13 may be, for example, rectangular blocks. Each set of first stopper blocks 12 includes two first stopper blocks 12, which are arranged on both sides of the lower end of the second side plate 20212. Here, the number of first stopper blocks 12 in each set may be one or more.

[0152] Such an arrangement of the first stopper block 12 and the stopper groove 20213 is advantageous in simplifying the structure of the protection door 2, provided that an effective stopper is realized.

[0153] In an embodiment of the present disclosure, the first stopper block 12 and the second side plate 20212 are connected so as to be integrally molded, and the bottom of the second side plate 20212 is the first stopper block 12. This configuration is considered to be advantageous not only for simplifying the structure of the protective door 2 but also for improving the strength of the protective door 2.

[0154] Of course, the first stopper block 12 may be independent of the second side plate 20212 so that the first stopper block 12 is connected to the lower end of the second side plate 20212, and this connection method may be, for example, an engagement connection, a screw connection, etc.

[0155] In some possible embodiments, as shown in FIG. 11, the bottom wall of the first side panel 20211 is connected to the main body segment 2111 and two side panels 2111a and 2111b provided on both sides of the main body segment 2111. seta first end of the inclined segment 2112 connected to the main body segment 2111 and a second end of the inclined segment 2112 connected to the first stopper block 12, the second end of the inclined segment 2112 being closer to the protective door panel 201 than the first end. This configuration can enlarge the stopper space of the stopper groove 20213, which is advantageous in improving the stopper effect.

[0156] In some possible embodiments, as shown in FIG. 1, the support base 1 includes a bottom support portion 101 and a side periphery portion 102. The bottom support portion 101 has two set The first via 11 is provided, and the lower end of the side periphery 102 is connected to the bottom support 101 .

[0157] As shown in Figures 9 and 10, the socket protective door structure further includes a stopper 7, which is disposed on the bottom support 101, and the tip of the stopper 7 is located in the second via 22 of the protective door panel 201, so that when the protective door 2 is tilted by inserting a single pin, the stopper 7 can abut against the wall of the second via 22.

[0158] For example, the stopper 7 is flat. When the protective door 2 tilts toward the insertion side during insertion of a single pin, the stopper 7 abuts against the wall of the second via 22 in the protective door 2, preventing the protective door 2 from further rotating. This prevents the protective door 2 from moving along the second direction D2, thereby protecting the plug bushing and further improving the effectiveness of preventing the insertion of a single pin. The provision of the stopper 7 also contributes to smooth resetting of the tilted protective door 2, and the stopper 7 blocks the view of the elastic reset member 3 from the outside, improving the aesthetics of the device.

[0159] With reference to the above configuration, the operation principle of the single pin insertion prevention of the socket protection door structure according to the embodiment of the present disclosure will now be exemplarily described.

[0160] As shown in Figure 12, when a thrust is applied to the left side of the protective door 2 in the initial state by inserting a single pin, the left end of the protective door 2 rotates downward, causing the left side of the protective door 2 to tilt in a direction approaching the bottom support portion 101, i.e., the left side of the protective door 2 to approach the first via 11 on the left side.In this way, the first stopper block 12 located on the left side of the protective door 2 enters the first via 11 located on the left side, and the first stopper block 12 cooperates with the second stopper block 13 in the first via 11 to realize a stop. 13, the second stopper block 13 enters the stopper groove 20213 formed in the protective door 2 by the first stopper block 12, forming a concave-convex positioning support. In this way, the protective door 2 is simultaneously stopped, blocking and protecting the first via 11 located on the left side. As a result, the single pin cannot pass through the protective door 2 and enter the plug bushing, achieving the purpose of preventing the insertion of a single pin. When the single pin is withdrawn, the protective door 2 is returned to its initial state by the elastic reset member 3.

[0161] As shown in Figure 14, when a thrust is applied to the right side of the protective door 2 in the initial state by inserting a single pin, the left end of the protective door 2 rotates downward, causing the right side of the protective door 2 to tilt in a direction approaching the bottom support part 101, i.e., the right side of the protective door 2 approaches the first via 11 on the right side.In this way, the first stopper block 12 located on the right side of the protective door 2 enters the first via 11 located on the right side, and the first stopper block 12 cooperates with the second stopper block 13 in the first via 11 to realize a stop. 15, the second stopper block 13 enters the stopper groove 20213 formed in the protective door 2 by the first stopper block 12, forming a concave-convex positioning support. In this way, the protective door 2 is simultaneously stopped, blocking and protecting the first via 11 located on the right side. As a result, the single pin cannot pass through the protective door 2 and enter the plug bushing, achieving the purpose of preventing the insertion of a single pin. When the single pin is withdrawn, the protective door 2 is returned to its initial state by the elastic reset member 3.

[0162] During the process of inserting a single pin, the stopper 7 can abut against the wall of the second via 22 in the protective door 2, thereby preventing the problem of fatigue damage to the elastic reset member 3 due to the pin being inserted at an angle.

[0163] As shown in FIG. 16 , the socket protection door structure according to the embodiment of the present disclosure further includes a cover 8, which has a jack corresponding to the jack of the socket, and the cover 8 is attached to the support base 1 so as to cover it, and the upper surface 21 of the protection door 2 is in close contact with the bottom surface of the cover 8.

[0164] For example, the cover 8 and the side periphery 102 of the support base 1 are connected by an engaging connection, and if the support base 1 has multiple side peripheries 102, the cover 8 can be engaged and connected to the multiple side peripheries 102 simultaneously so that the cover 8 confines the protective door 2 and the elastic reset member 3 inside the side periphery 102.

[0166] As described above, the bottom support 101 is provided with a stopper 7, and the stopper 7 has a first face wall for abutting against the wall of the second via 22 in the protective door 2. In some possible embodiments, as shown in Fig. 17, the socket protective door structure according to the embodiment of the present disclosure further includes a support block 81, which is disposed on the bottom surface of the cover 8. Referring to Fig. 15, the support block 81 is for abutting against a second face wall opposite to the first face wall of the stopper 7.

[0167] Illustratively, the stopper 7 is flat, with a first face wall of the stopper 7 being flat and a second face wall of the stopper 7 also being flat. Illustratively, the second face wall of the stopper 7 is further provided with a support groove, which is adapted to the structure of the support block 81 so that the support block 81 fits properly within the support groove and abuts against the second face wall in which the support groove is provided.

[0168] In some examples, the support block 81 does not abut against the second face wall of the stopper 7 before the wall of the second via 22 of the protective door 2 abuts against the stopper 7. In some examples, the support block 81 abuts against the second face wall of the stopper 7 after the wall of the second via 22 of the protective door 2 abuts against the stopper 7.

[0169] The support block 81 is provided to support the stopper 7, and in particular, when the protective door 2 is tilted to one side and abuts against the stopper 7, the stopper 7 receives a force and moves to the support block 81, which is advantageous in improving the fatigue resistance life of the stopper 7. The design of the support block 81 can also be used to prevent problems with installing the cover 8 in the wrong direction.

[0170] In the embodiment of the present disclosure, 1 set The above support blocks 81 are provided. For example, the support blocks 81 are set or 3 set and so on, and multiple Group of By having the support block 81 support the stopper 7 at the same time, the above effect can be further optimized. The number of support blocks 81 included in each set of support blocks 81 may be one or more.

[0171] In the embodiment of the present disclosure, the cover 8 and the side periphery 102 of the support base 1 are connected by an engagement connection, which will be exemplarily described below.

[0172] As shown in FIG. 17, the socket protection door structure further includes a positioning block 82, which is disposed on the bottom surface of the cover 8, and the support base 1 includes a bottom support portion 101 and a side periphery 102, and the positioning block 82 abuts against the outer wall of the side periphery 102 and is used to position the cover 8 on the support base 1.

[0173] A plurality of positioning blocks 82 are provided, and the plurality of positioning blocks 82 cooperate to form a positioning cavity, and one or more side peripheries 102 of the support base 1 are simultaneously located inside the positioning cavity, i.e., the walls of the positioning blocks 82 abut against the outer walls of the side peripheries 102, and the frictional force between them effectively fixes the cover 8 and the side peripheries 102, and further ensures that the jack on the cover 8 does not deviate.

[0174] 17, in some possible embodiments, the cover 8 includes a cover surface wall 801 and a cover side periphery 802, and the positioning block 82 and the jack are provided on the cover surface wall 801. Illustratively, the positioning block 82 provides positioning in the second direction D2 relative to the side periphery 102 of the support base 1, and a portion of the cover side periphery 802 provides positioning in the third direction D3 relative to the side periphery 102 of the support base 1, where the second direction D2 is the distribution direction of the N-pole jacks and the L-pole jacks, and the third direction D3 is a direction perpendicular to the second direction D2.

[0175] In another aspect, as shown in Figures 18 and 19, an embodiment of the present disclosure further provides a socket, which includes any of the socket protection door structures 100 described above.

[0176] By using the socket protection door structure 100 according to the embodiment of the present disclosure, the socket also has all the advantages of the socket protection door structure 100. do .

[0177] 18 and 19, in addition to the socket protection door structure 100, the socket according to the embodiment of the present disclosure further includes a panel 200, a fixing frame 300, and a plug bushing 400, wherein the panel 200 is attached to the cover to form a cover, the fixing frame 300 has a cavity for accommodating the support base 1 of the socket protection door structure 100, and the plug bushing 400 is fixed to the rear surface of the support base 1, and the fixing frame 300 is simultaneously fixedly connected to the panel 200 to sandwich the socket protection door structure 100 and the plug bushing 400 therebetween, thereby realizing stable arrangement of these components within the socket. Here, the plug bushing 400 includes at least an N-pole plug bushing and an L-pole plug bushing, and may further include an E-pole plug bushing.

[0178] For example, a socket according to an embodiment of the present disclosure may be a two-pole socket, a three-pole socket, or a five-hole socket formed by combining a two-pole socket and a three-pole socket.

[0179] The number of protective doors 2 in the socket protective door structure 100 is adaptively determined according to the number of plug bushings designed in the socket. In some examples, one support base 1 is designed in one socket, where one bottom support portion 101 of the support base 1 is designed, and the number of side peripheral portions 102 connected to the bottom support portion 101 corresponds one-to-one to the number of plug bushings in the socket. Correspondingly, the number of protective doors 2 and elastic reset members 3 also corresponds one-to-one to the number of plug bushings in the socket.

[0180] It should be noted that all such directional indications (e.g., up, down, left, right, etc.) in the embodiments of the present disclosure are used only to explain the relative positional relationships, movement conditions, etc. of each part in a specific posture (as shown in the figure), and when the specific posture changes, the directional indications also change correspondingly.
