Description

Technical Field

[0001] The present application relates to the technical field of electrical equipment, and particularly relates to a protection door structure and a socket. Background Art

[0002] As an electrical accessory, the socket is widely used in people's life and work, and the usage frequency of the socket is also very high, which makes the usage safety of the socket very important.

[0003] National standards require that a protection door structure should be provided in the socket to block the socket copper sheets and prevent the socket copper sheets from being exposed. In this way, the electric shock caused by improper operation can be effectively reduced, and the usage safety of the socket can be improved.

[0004] However, in the related art, the setting method of the protection door structure in the socket is unreasonable, so that the space occupied by the protection door structure is relatively large, and the volume of the socket is also large, thus increasing the cost of the socket. Utility Model Content

[0005] The present application provides a protection door structure and a socket, which can reduce the space occupied by the protection door structure and reduce the cost of the socket.

[0006] In a first aspect, the present application provides a protection door structure, including a housing, a first protection door, a second protection door and an elastic member. The protection door structure has a first direction. An installation cavity is provided inside the housing. The installation cavity has a cavity bottom, a first cavity wall and a second cavity wall opposite to each other along the first direction. The cavity bottom is provided with a first jack and a second jack. The first jack is close to the first cavity wall, and the second jack is close to the second cavity wall.

[0007] The first protection door slides in the installation cavity along the first direction. The second protection door slides in the installation cavity along the first direction. A part of the second protection door close to the first cavity wall is nested with the first protection door, and the first protection door and the second protection door can slide relative to each other along the first direction. The elastic member is arranged between the second protection door and the first protection door and can expand and contract along the first direction.

[0008] The elastic member is used to drive the first protection door to slide to block the first jack when the first jack is exposed, and to drive the second protection door to slide to block the second jack when the second jack is exposed.

[0009] In this way, since a part of the second protection door close to the first cavity wall is nested with the first protection door, the first protection door and the second protection door are partially overlapped, so that the space occupied by the first protection door and the second protection door in the first direction can be relatively small.

[0010] Based on this, the shell and the installation cavity can be made smaller in size in the first direction, thereby reducing the overall volume of the protective door structure, thereby reducing the manufacturing cost of the protective door structure.

[0011] Optionally, a first mounting hole is provided in the middle of the first protection door, and the first mounting hole penetrates the first protection door along the axis direction of the first plug hole, and a second mounting hole is provided in the middle of the second protection door, and the second mounting hole penetrates the second protection door along the axis direction of the first plug hole. The part of the second protection door facing the first protection door is embedded in the first mounting hole, and the part of the first protection door facing the second protection door is embedded in the second mounting hole.

[0012] The elastic member is arranged in the second mounting hole, and the two ends of the elastic member are respectively abutted against the second protective door and the part of the first protective door located in the second mounting hole, or the elastic member is arranged in the first mounting hole, and the two ends of the elastic member are respectively abutted against the first protective door and the part of the second protective door located in the first mounting hole.

[0013] In this way, the part of the second protection door facing the first protection door can be embedded in the first mounting hole, and the part of the first protection door facing the second protection door can also be embedded in the second mounting hole, thereby realizing the mutual nesting of the first protection door and the second protection door.

[0014] At this time, the elastic member can be arranged between the first protection door and the second protection door in different ways to provide driving force for the first protection door or the second protection door when the first protection door or the second protection door is reset.

[0015] Optionally, the second mounting hole has a first hole wall and a second hole wall opposite to each other, and when the elastic member is located in the second mounting hole, two ends of the elastic member abut against the second hole wall and the first protective door respectively. A driving hole is also provided on the first hole wall, and the driving hole is opposite to the first mounting hole. The driving hole has a third hole wall facing the second mounting hole, and the side of the third hole wall facing the cavity bottom is close to the elastic member, and the side of the third hole wall facing away from the cavity bottom is far away from the elastic member.

[0016] Since the side of the third hole wall facing the cavity bottom is close to the elastic member, and the side of the third hole wall facing away from the cavity bottom is far away from the elastic member, the third hole wall can be arranged tilted.

[0017] During the process of inserting the plug into the second jack, the inclined third hole wall has a guiding effect on the plug, which can facilitate the insertion of the plug and make the plugging of the plug on the socket smoother.

[0018] Optionally, a driving part is provided on the second protection door, the driving part is located in the first mounting hole, and the first protection door has a connecting part opposite to the driving part. The driving part has a first surface facing the connecting part, a side of the first surface close to the cavity bottom is away from the first cavity wall, and a side of the first surface away from the cavity bottom is close to the first cavity wall. The connecting part is inclined toward one side of the first surface and can cooperate with the driving part.

[0019] In this way, the first surface and the side of the connecting portion facing the first surface can be arranged inclined.

[0020] In the process of the connecting part and the driving part approaching each other, the first surface and the side of the connecting part facing the first surface can also approach each other for cooperation, thereby reducing the possibility of one of the first protective door and the second protective door contacting and interfering with the other of the first protective door and the second protective door during the sliding process.

[0021] Optionally, the first protective door includes a first body and a transmission member, the transmission member is connected to a side of the first body away from the first cavity wall, the first mounting hole is provided in the transmission member, and a portion of the transmission member facing the second protective door is embedded in the second mounting hole, and the first body can slide to cover the first plug hole or expose the first plug hole. A clamping member is provided on the first body and / or the transmission member, and a matching member is provided on the cavity bottom, the clamping member matches with the matching member, and the clamping member and the matching member can slide relative to each other.

[0022] In this way, the first protection door can be slidably arranged in the installation cavity through the clamping member.

[0023] Optionally, a limiting member is provided at the bottom of the cavity, the first insertion hole includes a first sub-hole and a second sub-hole arranged at intervals, the first body includes a first blocking portion and a second blocking portion arranged at intervals, the first blocking portion is used to block the first sub-hole or expose the first sub-hole, and the second blocking portion is used to block the second sub-hole or expose the second sub-hole.

[0024] The snap-on part can also rotate relative to the mating part. When the first blocking part or the second blocking part is subjected to force, the first protective door slides along the first direction and rotates relative to the shell so that the first protective door abuts against the limiting part, thereby limiting the first blocking part and the second blocking part, so that the first blocking part keeps covering the first sub-hole, and the second blocking part keeps covering the second sub-hole.

[0025] In this way, when only one of the first blocking part and the second blocking part is subjected to force, it can be considered that a foreign object is inserted into the socket instead of the plug. At this time, the limiting member can limit the first blocking part or the second blocking part to prevent the first protective door from opening, thereby playing a protective role.

[0026] Optionally, the first blocking portion has a first surface and a second surface opposite to each other, the first surface faces the cavity bottom. The second blocking portion has a third surface and a fourth surface opposite to each other, the third surface faces the cavity bottom.

[0027] One side of the fourth surface facing the engaging member is away from the bottom of the cavity, and one side of the fourth surface facing away from the engaging member is close to the bottom of the cavity. One side of the first surface facing the engaging member is close to the bottom of the cavity, and one side of the first surface facing away from the engaging member is away from the bottom of the cavity. And / or, one side of the third surface facing the engaging member is close to the bottom of the cavity, one side of the third surface facing away from the engaging member is away from the bottom of the cavity, one side of the second surface facing the engaging member is away from the bottom of the cavity, and one side of the second surface facing away from the engaging member is close to the bottom of the cavity.

[0028] In this way, when the user inserts the plug, even if the first blocking portion and the second blocking portion are unevenly stressed, causing the first protection door to rotate, the plug can still be inserted normally, improving the user's blind insertion experience.

[0029] Optionally, the second protection door includes a driving arm, a first blocking block, and a second blocking block. The first blocking block and the second blocking block are respectively connected to both sides of the driving arm, and the second mounting hole is provided on the driving arm. The second jack includes a first sub-slot, a second sub-slot, and a third sub-slot. When the second protection door blocks the second jack, the part of the driving arm without the second mounting hole blocks the first sub-slot, the first blocking block blocks the second sub-slot, and the second blocking block blocks the third sub-slot. A boss is provided at the bottom of the cavity, and a mounting groove is provided on the side of the driving arm facing the bottom of the cavity. The boss is slidably sleeved in the mounting groove.

[0030] In this way, the driving arm can cooperate with the boss at the bottom of the cavity through the engaging groove, so that the second protection door can slide relative to the bottom of the cavity.

[0031] Optionally, an engaging member is provided on the side of the first protection door facing the bottom of the cavity, and a cooperating member is provided on the boss. The engaging member cooperates with the cooperating member.

[0032] In this way, both the first protection door and the second protection door can be slidably connected to the housing through the boss. The boss, as a common part of the first protection door and the second protection door, on the one hand, makes the structure of the protection door simple and convenient for assembly.

[0033] On the other hand, it can also make the connection layout of the first protection door and the second protection door reasonable, occupy less space, and reduce the possibility of setting multiple structures to cooperate with the first protection door and the second protection door respectively, increasing the occupied space.

[0034] In a second aspect, the present application provides a socket including the protection door structure according to any one of the first aspects above.

[0035] For what is provided in the above second aspect and each possible design of the second aspect, the beneficial effects can refer to the beneficial effects brought by the above first aspect and each possible implementation manner of the first aspect, which will not be elaborated here.

[0059] Exemplarily, an embodiment of the present application provides a socket, and the socket includes a protection door structure 100 as Figure 1 shown.

[0060] A socket is an electrical accessory that can provide a power interface for electrical appliances. It has a wide range of usage scenarios, and its safety is extremely important.

[0061] In the socket provided with the above-mentioned protection door structure 100, the protection door structure 100 can block conductive components such as copper sheets in the socket, and can reduce the occurrence of electric shock caused by children or other foreign objects inserting fingers or other foreign objects into the socket, thereby improving the safety performance of the socket during use.

[0062] Among them, the socket has different types. For example, a socket adapter, a flush-mounted socket, a track socket, etc. The protection door structure 100 proposed in the embodiments of the present application can be provided for different types of sockets to improve the use safety of the socket.

[0063] The protection door structure 100 provided in the embodiments of the present application will be introduced in detail below with reference to the accompanying drawings.

[0064] Referring to Figure 1 and Figure 2 shown, the present application provides a protection door structure 100, which includes a housing 10, a first protection door 20, a second protection door 30, and an elastic member 40. The protection door structure 100 has a first direction X. An installation cavity 11 is provided inside the housing 10. The installation cavity 11 has a cavity bottom 111, a first cavity wall 112 and a second cavity wall 113 opposite to each other along the first direction X. The cavity bottom 111 is provided with a first jack 114 and a second jack 115. The first jack 114 is close to the first cavity wall 112, and the second jack 115 is close to the second cavity wall 113.

[0065] The first protection door 20 slides in the installation cavity 11 along the first direction X. The second protection door 30 slides in the installation cavity 11 along the first direction X. A part of the second protection door 30 close to the first cavity wall 112 is nested with the first protection door 20, and the first protection door 20 and the second protection door 30 can slide relative to each other along the first direction X. The elastic member 40 is disposed between the second protection door 30 and the first protection door 20 and can expand and contract along the first direction X.

[0066] The elastic member 40 is used to drive the first protection door 20 to slide when the first jack 114 is exposed, so that the first protection door 20 shields the first jack 114, and is used to drive the second protection door 30 to slide when the second jack 115 is exposed, so that the second protection door 30 shields the second jack 115.

[0067] The protection door structure 100 includes a housing 10, a first protection door 20, a second protection door 30, and an elastic member 40. The housing 10 can serve as a support structure in the protection door structure 100, providing an installation space for the first protection door 20, the second protection door 30, and the elastic member 40. The first protection door 20, the second protection door 30, and the elastic member 40 can all be arranged in the installation cavity 11 inside the housing 10.

[0068] Wherein, the installation cavity 11 has a cavity bottom 111, a first cavity wall 112, and a second cavity wall 113, and can be shielded by the jacks provided on the cavity bottom 111 through the first protection door 20 and the second protection door 30.

[0069] Specifically, the jacks include a first jack 114 and a second jack 115. The first protection door 20 is arranged on one side of the installation cavity 11 close to the first cavity wall 112 and can shield the first jack 114. The second protection door 30 is arranged on one side of the installation cavity 11 close to the second cavity wall 113 and can shield the second jack 115.

[0070] In this way, the possibility of electric shock caused by directly inserting a finger or other foreign objects into the first jack 114 or the second jack 115 can be reduced.

[0071] In the embodiment of the present application, both the first protection door 20 and the second protection door 30 can slide along the first direction X. In this way, when plugging a plug into the socket, the plug can drive the first protection door 20 or the second protection door 30 to slide, so that the first jack 114 or the second jack 115 is exposed. Thus, the plug can extend into the first jack 114 or the second jack 115 and be electrically connected to conductive components such as copper sheets in the socket.

[0072] The elastic member 40 is arranged between the second protection door 30 and the first protection door 20 and can expand and contract along the first direction X. Based on this, the elastic member 40 can push against the first protection door 20 and the second protection door 30, so that after the plug is unplugged, the first protection door 20 or the second protection door 30 can reset and re-shield the first jack 114 or the second jack 115.

[0073] Specifically, when a plug is inserted into the first jack 114, the plug can push the first protection door 20 to slide, so that the first jack 114 is exposed. During this process, the first protection door 20 can compress the elastic member 40, so that the elastic member 40 has elastic potential energy.

[0074] After the plug is pulled out of the first jack 114, the elastic member 40 can recover its deformation under its own elasticity and push against the first protection door 20 to make the first protection door 20 slide in the direction close to the first cavity wall 112, so that the first protection door 20 can block the first jack 114.

[0075] Similarly, when a plug is inserted into the second jack 115, the plug can push the second protection door 30 to slide, and the second protection door 30 can compress the elastic member 40, so that the elastic member 40 has elastic potential energy.

[0076] After the plug is pulled out of the second jack 115, the elastic member 40 can recover its deformation under its own elasticity and push against the second protection door 30 to make the second protection door 30 slide in the direction close to the second cavity wall 113, so that the second protection door 30 can block the second jack 115.

[0077] Since a part of the second protection door 30 close to the first cavity wall 112 is nested with the first protection door 20, a part of the first protection door 20 and the second protection door 30 are overlapped, which can make the space occupied by the first protection door 20 and the second protection door 30 in the first direction X smaller.

[0078] In this way, the size of the housing 10 and the installation cavity 11 in the first direction X can be smaller, reducing the overall volume of the protection door structure 100, and further reducing the manufacturing cost of the protection door structure 100.

[0079] For the socket provided with the above protection door structure 100, the space occupied by the protection door structure 100 in the socket can also be smaller, which is convenient for reducing the overall volume of the socket and is also beneficial to the layout of the protection door structure 100 in the socket, saving the material cost of the socket.

[0080] In the related art, the two protection doors are generally arranged at intervals in the first direction X. The elastic member is arranged between the two protection doors, and both ends of the elastic member are respectively abutted against the same side of the two protection doors.

[0081] In this way, the size of the protection door structure in the first direction includes the sizes of the two protection doors in the first direction and the size of a part of the elastic member in the first direction.

[0082] However, for the protection door structure 100 proposed in this application, its size in the first direction X is smaller than the sum of the size of the first protection door 20 in the first direction X and the size of the second protection door 30 in the first direction X. It can be seen that, compared with the related art, the volume of the protection door structure 100 proposed in this application is smaller.

[0083] It should be noted that the elastic member 40 can be a spring, a spring plate or other components made of elastic materials. The specific type of the elastic member 40 is not specifically limited in the embodiments of the present application.

[0084] It should also be noted that the first protection door 20 and the second protection door 30 can be set according to the type of the socket.

[0085] For example, as Figure 1 and Figure 2 shown, the socket can be a five-hole socket. At this time, the first jack 114 can be a two-pin jack, and the second jack 115 can be a three-pin jack. Correspondingly, the first protection door 20 can be a two-pin protection door, and the second protection door 30 can be a three-pin protection door.

[0086] Or, the socket can also be a four-hole socket. At this time, both the first jack 114 and the second jack 115 can be two-pin jacks, and both the first protection door 20 and the second protection door 30 can be two-pin protection doors.

[0087] The specific setting manner of the first protection door 20 and the second protection door 30 is not specifically limited in the embodiments of the present application.

[0088] In order to make the structure and principle of the present application clearer, here, the working mode of the protection door structure 100 proposed in the present application is described in conjunction.

[0089] The direction from the first cavity wall 112 to the second cavity wall 113 is defined as the positive direction of the first direction X, and the direction from the second cavity wall 113 to the first cavity wall 112 is defined as the reverse direction of the first direction X.

[0090] When inserting a plug into the first jack 114, the plug can apply a force to the first protection door 20, causing the first protection door 20 to slide in the reverse direction of the first direction X and push against the elastic member 40, so that the first jack 114 is exposed, as Figure 3 shown.

[0091] When pulling the plug out of the first jack 114, the plug can cancel the force applied to the first protection door 20. At this time, the elastic member 40 pushes the first protection door 20 under its own elastic force, causing the first protection door 20 to slide in the positive direction of the first direction X. Thus, the first protection door 20 can cover the first jack 114 again.

[0092] When inserting a plug into the second jack 115, the plug can apply a force to the second protection door 30, causing the second protection door 30 to slide in the positive direction of the first direction X and push against the elastic member 40, so that the second jack 115 is exposed, as Figure 4 shown.

[0093] When the plug is pulled out from the second jack 115, the plug can cancel its acting force on the second protection door 30. At this time, the elastic member 40 pushes the second protection door 30 under the action of its own elastic force, so that the second protection door 30 slides in the reverse direction of the first direction X. Thus, the second protection door 30 can block the second jack 115 again.

[0094] It can be seen that during the process of inserting the plug into the first jack 114, the first protection door 20 slides in the reverse direction of the first direction X. During the process of inserting the plug into the second jack 115, the second protection door 30 slides in the positive direction of the first direction X. The actions of the first protection door 20 and the second protection door 30 to expose the jacks are different.

[0095] In some embodiments, as Figure 2 , Figure 5 and Figure 6 shown, a first mounting hole 201 is provided in the middle of the first protection door 20. The first mounting hole 201 penetrates the first protection door 20 along the axial direction of the first jack 114. A second mounting hole 301 is provided in the middle of the second protection door 30. The second mounting hole 301 penetrates the second protection door 30 along the axial direction of the first jack 114.

[0096] In this way, a part of the second protection door 30 facing the first protection door 20 can be embedded in the first mounting hole 201, and at the same time, a part of the first protection door 20 facing the second protection door 30 can also be embedded in the second mounting hole 301, realizing the mutual nesting of the first protection door 20 and the second protection door 30.

[0097] The elastic member 40 can be arranged in the second mounting hole 301, and both ends of the elastic member 40 are respectively abutted against the second protection door 30 and a part of the first protection door 20 located in the second mounting hole 301.

[0098] Alternatively, the elastic member 40 can also be arranged in the first mounting hole 201, and both ends of the elastic member 40 are respectively abutted against the first protection door 20 and a part of the second protection door 30 located in the first mounting hole 201.

[0099] That is, the elastic member 40 can be arranged in the second mounting hole 301, or it can also be arranged in the first mounting hole 201. In these two arrangement methods, both ends of the elastic member 40 can be abutted against the second protection door 30 and the first protection door 20, which is convenient for the elastic member 40 to push the first protection door 20 or the second protection door 30 to reset.

[0100] For the convenience of description, the state where no plug is inserted in the protection door structure 100 is called the initial state.

[0101] It should be noted that whether the elastic member 40 is disposed in the first mounting hole 201 or the second mounting hole 301, in the initial state, the elastic member 40 can be in a pre-compressed state. Thus, in the initial state, the elastic member 40 has a tendency to elongate and exerts a pushing force on the first protection door 20 and the second protection door 30.

[0102] Therefore, in the initial state, the elastic member 40 can push the first protection door 20 away from the second protection door 30, so that the first protection door 20 can abut against the first cavity wall 112. At the same time, the elastic member 40 can push the second protection door 30 away from the first protection door 20, so that the second protection door 30 can abut against the second cavity wall 113.

[0103] In this way, in the initial state, the possibility that the positions of the first protection door 20 and the second protection door 30 in the accommodation cavity are not fixed, resulting in easy sliding of the first protection door 20 and the second protection door 30, and thus failure of the first protection door 20 and the second protection door 30 can be reduced.

[0104] In addition, in the present application, the first protection door 20 and the second protection door 30 share the elastic member 40. When a plug is inserted into the first jack 114 or the second jack 115, the protection door corresponding to the jack without the inserted plug can abut against the housing 10 and will not slide, and the possibility of incorrect exposure of the other jack when a plug is inserted into one jack can also be reduced.

[0105] When the distance between the first jack 114 and the second jack 115 is small, plugs cannot be inserted into the first jack 114 and the second jack 115 simultaneously. At this time, it can be set that in the initial state, the nested parts of the first protection door 20 and the second protection door 30 are more, which can further reduce the volume of the protection door structure 100.

[0106] It should also be noted that when the socket is a five-hole socket, the second protection door 30 is a three-prong protection door. At this time, the second protection door 30 needs to be able to block the three-prong jack, so that the size of the three-prong protection door in the first direction X is larger.

[0107] In this way, the size of the second mounting hole 301 can also be larger. As a preferred method, the elastic member 40 can be disposed in the second mounting hole 301, as Figure 1 and Figure 5 shown. Based on this, it is convenient to arrange the elastic member 40, and the possibility that the elastic member 40 is excessively compressed and easily broken due to the small installation space of the elastic member 40 can be reduced.

[0108] At this time, a guide column 35 may be provided on the hole wall of the second mounting hole 301 facing the first cavity wall 112, and the elastic member 40 may be sleeved on the guide column 35, and the guide column 35 may guide the expansion and contraction of the elastic member 40, such as Figure 4 and Figure 5 shown.

[0109] like Figure 6 As shown, an abutment member 24 may also be provided on the first protective door 20 . The abutment member 24 is located in the second mounting hole 301 and may abut against the elastic member 40 , thereby providing a position for the elastic member 40 to abut against the first protective door 20 .

[0110] When the elastic member 40 is arranged in the first mounting hole 201, the first mounting hole 201 may be insufficient in size, which is not conducive to the installation of the elastic member 40. In this case, it is necessary to additionally provide a protruding structure on the side of the first protection door 20 away from the second cavity wall 113, and then provide a groove for accommodating the elastic member 40 in the protruding structure, so that the two ends of the elastic member 40 are respectively in contact with the second protection door 30 and the bottom of the groove.

[0111] However, this arrangement, due to the additional protruding structure, will make the volume of the protective door structure 100 larger than the method in which the elastic member 40 is arranged in the second mounting hole 301. That is, when the elastic member 40 is arranged in the second mounting hole 301, the volume reduction effect of the protective door structure 100 is better.

[0112] In addition, the arrangement of the first protection door 20 , the second protection door 30 and the elastic member 40 proposed in the present application also facilitates the assembly of the protection door structure 100 .

[0113] Combination Figure 1 and Figure 7 When assembling the protection door structure 100, the first protection door 20 can be firstly arranged in the installation cavity 11, and then the second protection door 30 can be arranged in the installation cavity 11, and finally the elastic member 40 can be arranged between the first protection door 20 and the second protection door 30. The whole assembly process conforms to the engineering principle.

[0114] In addition, during the assembly process, the elastic member 40 with a smaller volume is installed at the back, which can reduce the possibility that the elastic member 40 is blocked during the assembly process, making it inconvenient to observe the state of the elastic member 40. At the same time, it can also reduce the insertion during the assembly process, making it easier to achieve automation. When the protective door structure 100 is manually assembled, the assembly efficiency is also high.

[0115] In addition, in the present application, the first protection door 20 and the second protection door 30 can be supported by the same elastic member 40 and driven to reset.

[0116] In this way, the present application can realize the function of the protective door structure 100 by using only one elastic member 40, which can reduce the use of parts of the protective door structure 100 and facilitate assembly.

[0117] Of course, in order to improve the reliability of the elastic member 40 resetting the first protection door 20 and the second protection door 30, a plurality of elastic members 40 that can be extended and retracted along the first direction X can also be provided to drive the first protection door 20 or the second protection door 30 to reset through the plurality of elastic members 40.

[0118] In some embodiments, Figure 1 and Figure 5 As shown, the second mounting hole 301 may have a first hole wall 302 and a second hole wall 303 opposite to each other. When the elastic member 40 is located in the second mounting hole 301 , the end of the elastic member 40 abutting against the second protective door 30 may specifically abut against the second hole wall 303 .

[0119] The first hole wall 302 is a hole wall in the second installation hole 301 close to the first cavity wall 112 , and the second hole wall 303 is a hole wall in the second installation hole 301 close to the second cavity wall 113 .

[0120] like Figures 2 to 7 As shown, a driving hole 304 is also provided on the first hole wall 302, and the driving hole 304 is opposite to the first mounting hole 201. The driving hole 304 has a third hole wall 305 facing the second mounting hole 301, and the side of the third hole wall 305 facing the cavity bottom 111 is close to the elastic member 40, and the side of the third hole wall 305 facing away from the cavity bottom 111 is far away from the elastic member 40.

[0121] The driving hole 304 is arranged on the first hole wall 302, so that the driving hole 304 can be connected with the second mounting hole 301. In this way, when the second protection door 30 slides in the positive direction of the first direction X by inserting the plug, the first hole wall 302 can slide in the positive direction of the first direction X accordingly.

[0122] During this process, the position of the first protection door 20 remains unchanged, so that the relative position of the first protection door 20 and the second mounting hole 301 changes, and the plug can enter the second plug hole 115 through the driving hole 304 and the second mounting hole 301.

[0123] Since the side of the third hole wall 305 facing the cavity bottom 111 is close to the elastic member 40 and the side of the third hole wall 305 facing away from the cavity bottom 111 is far away from the elastic member 40 , the third hole wall 305 can be arranged tilted.

[0124] During the process of inserting the plug into the second jack 115, the inclined third jack wall 305 guides the plug, which can facilitate the insertion of the plug and make the plugging of the plug on the socket smoother.

[0125] In addition, since the first mounting hole 201 is a through hole penetrating the first protection door 20, a part of the second protection door 30 located in the first mounting hole 201 can abut against the cavity bottom 111. In this way, the height of the position where the driving hole 304 is provided on the second protection door 30 can be relatively large, so that the depth of the driving hole 304 in the axial direction of the second jack 115 can also be relatively large.

[0126] Based on this, the inclination degree of the third hole wall 305 can be set to be relatively large, so as to improve the smoothness of the plug insertion when the plug is inserted into the second jack 115.

[0127] Wherein, the height of the position where the driving hole 304 is provided on the second protection door 30 refers to the dimension of this position in the axial direction of the second jack 115.

[0128] It should be noted that in the embodiment of the present application, the second protection door 30 is a three-pin protection door, and the second protection door 30 slides in an E-pole driving manner to expose the second jack 115. The driving hole 304 is the insertion position of the E-pole of the plug. When the plug is inserted, the plug can abut against the third hole wall 305 and push the second protection door 30 to slide in the positive direction of the first direction X.

[0129] In the embodiment of the present application, the position of the second protection door 30 for inserting the E-pole is arranged in a single layer. Compared with the double-layer manner in which the position of the second protection door 30 for inserting the E-pole and the first protection door 20 are stacked, the height of the position of the second protection door 30 for inserting the E-pole in the present application is relatively large, which is convenient for setting the third hole wall 305 with a relatively large inclination degree, can improve the smoothness of the plug insertion, and improve the feel when inserting the plug.

[0130] In some embodiments, as Figure 1 、 Figures 6 to 8 shown, the second protection door 30 may be provided with a driving part 31. The driving part 31 is located in the first mounting hole 201, and the first protection door 20 has a connecting part 211 opposite to the driving part 31. The driving part 31 has a first surface 311 facing the connecting part 211. The side of the first surface 311 close to the cavity bottom 111 is far from the first cavity wall 112, and the side of the first surface 311 far from the cavity bottom 111 is close to the first cavity wall 112. The side of the connecting part 211 facing the first surface 311 is inclined and can cooperate with the first surface 311.

[0131] The driving part 31 is located in the first mounting hole 201. When a plug is inserted into the first jack 114 or the second jack 115, the first protection door 20 or the second protection door 30 can slide in the mounting cavity 11, so that the relative position between the first mounting hole 201 and the driving part 31 changes, and further the connecting part 211 and the driving part 31 can approach each other.

[0132] In the embodiment of the present application, since one side of the first surface 311 close to the cavity bottom 111 is far from the first cavity wall 112, and the side of the first surface 311 far from the cavity bottom 111 is close to the first cavity wall 112, therefore, the first surface 311 is inclined.

[0133] And the side of the connecting portion 211 facing the first surface 311 is also inclined. Therefore, during the process of the connecting portion 211 and the driving portion 31 approaching each other, the first surface 311 and the side of the connecting portion 211 facing the first surface 311 can also approach each other for cooperation.

[0134] In this way, during the sliding process of one of the first protection door 20 and the second protection door 30, the possibility of interference with the other of the first protection door 20 and the second protection door 30 can be reduced.

[0135] Reference Figure 7 , the inclination directions of the first surface 311 and the side of the connecting portion 211 facing the first surface 311 can be the same, and the effect of reducing the possibility of interference between the first protection door 20 and the second protection door 30 is better.

[0136] Among them, the side of the connecting portion 211 facing the first surface 311 can be a second surface parallel or approximately parallel to the first surface 311. Or, as Figure 7 shown, the side of the connecting portion 211 facing the first surface 311 can also be a stepped structure, which can also prevent interference between the first protection door 20 and the second protection door 30.

[0137] It should be noted that, continuing to refer to Figure 7 , the first surface 311 and the third hole wall 305 can be two surfaces opposite to the driving portion 31. The first surface 311 and the third hole wall 305 can both be inclined.

[0138] Among them, the second protection door 30 is a plastic part and can be formed by injection molding. The first surface 311 and the third hole wall 305 can be parallel, so that the wall thickness of the driving portion 31 obtained by injection molding is uniform, and when the wall thickness difference of the driving portion 31 is large, the possibility of shrinkage problems and cracking of the driving portion 31 is reduced.

[0139] Of course, the first surface 311 and the third hole wall 305 can also be not parallel, and the included angle between the first surface 311 and the third hole wall 305 is small. In this way, the occurrence of tolerances in the production process can be adapted, the product yield can be improved, and the possibility of a large difference in the wall thickness of the driving portion 31 can also be reduced.

[0140] In some embodiments, such as Figure 1 , Figure 2 , Figure 6 andFigure 9 As shown in the figure, the first protection door 20 may include a first body 21 and a transmission member 22. The transmission member 22 is connected to a side of the first body 21 facing away from the first cavity wall 112. A first mounting hole 201 is provided in the transmission member 22. A part of the transmission member 22 facing the second protection door 30 is embedded in the second mounting hole 301. The first body 21 is slidable to block or expose the first jack 114.

[0141] That is, the first protection door 20 can block the first jack 114 through the first body 21 to play a protective role. The transmission member 22 can be connected to the first body 21 to realize the nesting of the first protection door 20 and the second protection door 30.

[0142] In the embodiment of the present application, as shown in Figure 1 、 Figure 2 and Figure 9 shown, a clamping member 23 may be provided on the first protection door 20, and a mating member 116 is provided on the cavity bottom 111. The clamping member 23 cooperates with the mating member 116, and the clamping member 23 and the mating member 116 are relatively slidable.

[0143] In this way, the first protection door 20 can be slidably arranged in the installation cavity 11 through the clamping member 23.

[0144] Among them, both the first body 21 and the transmission member 22 have surfaces facing the cavity bottom 111. The clamping member 23 may be provided on the first body 21 or may be provided on the transmission member 22 so that the clamping member 23 can cooperate with the mating member 116.

[0145] Of course, clamping members 23 may also be provided on both the first body 21 and the transmission member 22, as shown in Figure 9 shown. In this way, there are more mating positions between the first protection door 20 and the cavity bottom 111, which can improve the reliability of the slidable connection between the first protection door 20 and the cavity bottom 111 and improve the smoothness of the sliding of the first protection door 20.

[0146] It should be noted that the clamping member 23 and the mating member 116 may have different setting methods. For example, the clamping member 23 may be a protrusion 231, and the mating member 116 may be a groove 1161. The protrusion 231 may be embedded in the groove 1161, as shown in Figure 2 、 Figures 9 to 11 shown.

[0147] Alternatively, the clamping member 23 may be a clamping groove, and the mating member 116 may be a clamping protrusion 231. The clamping protrusion 231 may be embedded in the clamping groove. The specific setting methods of the clamping member 23 and the mating member 116 are not specifically limited in the embodiment of the present application.

[0148] Generally speaking, the first protection door 20 is made of nylon and glass fiber, so that the first protection door 20 has a relatively high hardness. In order to prevent the first protection door 20 from scratching or damaging the housing 10 during the sliding process, which causes the first protection door 20 to fail to slide normally, the specific forms of the clamping member 23 and the matching member 116 can be specifically set according to the material of the housing 10.

[0149] Specifically, when the housing 10 is made of polypropylene (PP), the fitting 116 may be in the form of a groove 1161. In this way, when the housing 10 is provided with the clamping protrusion 231, the possibility that the clamping protrusion 231 is relatively small in hardness and is easy to scrape the glue can be reduced.

[0150] When the housing 10 is made of polycarbonate (PC), the hardness of the housing 10 is also relatively large, which can reduce the possibility of damage to the housing 10. At this time, the matching member 116 can be a groove 1161 or a clamping protrusion 231. Correspondingly, the clamping member 23 can be a protrusion 231 or a clamping groove.

[0151] Similarly, the second protection door 30 can also be made of nylon and glass fiber materials.

[0152] It should also be noted that the first mounting hole 201 can be disposed in the middle of the transmission member 22 , that is, the transmission member 22 is a hollow structure.

[0153] Alternatively, the first mounting hole 201 may also be formed by the cooperation of the transmission member 22 and the first body 21. Figure 9 The transmission member 22 may be a structure similar to the Chinese character "冂", and one side of the transmission member 22 is provided with an opening. The side of the transmission member 22 provided with the opening is connected to the first body 21, and can cooperate with the first body 21 to form a first mounting hole.

[0154] In some embodiments, Figure 1 , Figure 2 and Figure 6 As shown, a limiting member 117 is provided at the cavity bottom 111, the first insertion hole 114 includes a first sub-hole and a second sub-hole arranged at intervals, and the first protective door 20 includes a first blocking portion 212 and a second blocking portion 213 arranged at intervals, the first blocking portion 212 is used to block the first sub-hole, or expose the first sub-hole, and the second blocking portion 213 is used to block the second sub-hole, or expose the second sub-hole.

[0155] In the embodiment of the present application, the first plug hole 114 is a two-plug plug hole, including a first sub-hole and a second sub-hole.

[0156] Correspondingly, the first protection door 20 is a two-pin protection door, including a first blocking portion 212 that can block the first sub-hole and a second blocking portion 213 that can block the second sub-hole. Therefore, the first protection door 20 can protect the first jack 114 when no plug is inserted into the first jack 114.

[0157] The engaging member 23 can also rotate relative to the mating member 116. When the first blocking portion 212 or the second blocking portion 213 is stressed, the first protection door 20 slides along the first direction X and rotates relative to the housing 10, so that the first protection door 20 abuts against the limiting member 117, limiting the first blocking portion 212 and the second blocking portion 213, so that the first blocking portion 212 keeps blocking the first sub-hole and the second blocking portion 213 keeps blocking the second sub-hole.

[0158] That is, in the embodiment of the present application, in addition to being able to slide relative to the mating member 116, the engaging member 23 can also rotate relative to the mating member 116.

[0159] In this way, when a plug is normally inserted into the first jack 114, the plug can apply forces to both the first blocking portion 212 and the second blocking portion 213, so that both sides of the first protection door 20 are stressed. At this time, the stress of the first protection door 20 is relatively balanced, and it can slide in the installation cavity 11 to expose the first sub-hole and the second sub-hole, so that the plug can be electrically connected to the copper sheet in the socket through the first sub-hole and the second sub-hole.

[0160] When a foreign object is inserted into the socket, causing one side of the first protection door 20 to be stressed, the first protection door 20 can rotate in the installation cavity 11 while sliding. When the first protection door 20 slides to abut against the limiting member 117, the limiting member 117 can limit the first protection door 20 to prevent it from continuing to slide in the installation cavity 11, so that the first protection door 20 can still block the first sub-hole and the second sub-hole, playing a role in preventing single-pole insertion.

[0161] That is, when both the first blocking portion 212 and the second blocking portion 213 are stressed, the first protection door 20 can slide normally, so that the first protection door 20 opens to facilitate the insertion of the plug.

[0162] When only one of the first blocking portion 212 and the second blocking portion 213 is stressed, it can be considered that a foreign object is inserted into the socket instead of the plug. At this time, the limiting member 117 can limit the first blocking portion 212 or the second blocking portion 213 to prevent the first protection door 20 from opening, playing a protective role.

[0163] Among them, as Figure 2 shown, the number of the limiting members 117 can be multiple, and the multiple limiting members 117 are distributed on both sides of the cavity bottom 111.

[0164] Some of the plurality of limit members 117 are used to abut against the first blocking portion 212, and the other part of the limit members 117 are used to abut against the second blocking portion 213.

[0165] For the convenience of description, the limit member 117 on the same side as the first blocking portion 212 is referred to as the first limit member 117, and the limit member 117 on the same side as the second blocking portion 213 is referred to as the second limit member 117.

[0166] Reference Figure 6 and Figure 10 to protect the door structure 100 in accordance with Figure 10 Taking the illustrated position placement as an example, a limit member 117 is provided on each side of the cavity bottom 111. When the second blocking portion 213 is stressed, the first protection door 20 can rotate clockwise so that the second blocking portion 213 can abut against the second limit member 117.

[0167] When the first blocking portion 212 is stressed, the first protection door 20 can rotate counterclockwise so that the first blocking portion 212 can abut against the first limit member 117.

[0168] It should be noted that since the first protection door 20 will have a certain sliding when the first jack 114 is inserted unipolarly and then will abut against the limit member 117 to limit the first protection door 20. In order to further reduce the possibility of foreign objects entering the first jack 114, there may be a distance between the first jack 114 and the first cavity wall 112 so that the first jack 114 is not exposed during the sliding process of the first protection door 20 before abutting against the limit member 117.

[0169] It should also be noted that in order to prevent the setting of the limit member 117 from affecting the normal opening of the first protection door 20, there may be a spacing between the first blocking portion 212 and the first limit member 117, and between the second blocking portion 213 and the second limit member 117 in the axial direction of the first sub-hole.

[0170] In this way, when a plug is normally inserted into the first jack 114, the first protection door 20 can slide, and through the positions where the first limit member 117 and the second limit member 117 are provided, the plug can be normally inserted.

[0171] Among them, the aforementioned connecting portion 211, as a part of the first protection door, can be located on the first body 21 and is connected between the first blocking portion 212 and the second blocking portion 213.

[0172] Such as Figure 6 and Figure 10As shown, the first blocking portion 212 has a first surface 214 and a second surface 215 opposite to each other, and the first surface 214 faces the cavity bottom 111 . The second blocking portion 213 has a third surface 216 and a fourth surface 217 opposite to each other, and the third surface 216 faces the cavity bottom 111 .

[0173] In order to further improve the safety of the socket, a cover plate is also provided on the housing 10 to shield the first protection door 20, the second protection door 30 and the elastic member 40. Since the first surface 214 is opposite to the second surface 215, and the third surface 216 is opposite to the fourth surface 217, the second surface 215 and the fourth surface 217 face the cover plate.

[0174] When a user normally inserts a plug into a socket, it is difficult to ensure that the forces on the first blocking portion 212 and the second blocking portion 213 are consistent. Therefore, when the plug is normally inserted, the first protective door 20 may abut against the stopper 117, causing the first protective door 20 to fail to open normally, and thus the plug cannot be inserted.

[0175] In order to reduce the possibility of the above problems, the first blocking portion 212 and the second blocking portion 213 may be improved as follows to enhance the user's experience of inserting the plug.

[0176] like Figure 2 , Figure 9 and Figure 10 The side of the fourth surface 217 facing the clamping member 23 is far from the cavity bottom 111, the side of the fourth surface 217 facing away from the clamping member 23 is close to the cavity bottom 111, the side of the first surface 214 facing the clamping member 23 is close to the cavity bottom 111, and the side of the first surface 214 facing away from the clamping member 23 is far from the cavity bottom 111.

[0177] In this way, the first surface 214 and the fourth surface 217 are both inclined. When the first blocking portion 212 is subjected to greater force, the first protection door 20 can rotate counterclockwise, so that the first surface 214 rotates toward the side close to the cavity bottom 111, and the fourth surface 217 rotates toward the side away from the cavity bottom 111.

[0178] The inclined arrangement of the first surface 214 and the fourth surface 217 can increase the travel of the first protection door 20 in counterclockwise rotation, so that the first protection door 20 can rotate at a larger angle. Therefore, the possibility of the first protection door 20 not being able to open normally due to the first surface 214 abutting against the first stopper 117 and the fourth surface 217 abutting against the cover body after the first protection door 20 rotates at a small angle can be reduced.

[0179] Based on this, when the user inserts the plug, even if the first blocking portion 212 and the second blocking portion 213 are subjected to uneven force, causing the first protective door 20 to rotate counterclockwise, the plug can still be inserted normally, thereby improving the user's blind plugging experience.

[0180] In order to provide users with a better plug insertion experience and to provide a single-pole plug protection effect, the inclination of the first surface 214 and the fourth surface 217 may be set so that the counterclockwise rotation angle of the first protection door 20 is between 0-5°.

[0181] Alternatively, the side of the third surface 216 facing the clamp 23 is close to the cavity bottom 111, and the side of the third surface 216 facing away from the clamp 23 is away from the cavity bottom 111, the side of the second surface 215 facing the clamp 23 is away from the cavity bottom 111, and the side of the second surface 215 facing away from the clamp 23 is close to the cavity bottom 111.

[0182] In this way, the second surface 215 and the third surface 216 are both inclined. When the second blocking portion 213 is subjected to a large force, the first protection door 20 can rotate clockwise, so that the third surface 216 rotates toward the side close to the cavity bottom 111, and the second surface 215 rotates toward the side away from the cavity bottom 111. Figure 11 shown.

[0183] The inclined arrangement of the third surface 216 and the second surface 215 can increase the travel of the first protection door 20 in clockwise rotation, so that the first protection door 20 can rotate at a larger angle. Therefore, the possibility of the first protection door 20 not being able to open normally due to the third surface 216 abutting against the second stopper 117 and the second surface 215 abutting against the cover body after the first protection door 20 rotates at a small angle can be reduced.

[0184] Based on this, when the user inserts the plug, even if the first blocking portion 212 and the second blocking portion 213 are subjected to uneven force, causing the first protection door 20 to rotate clockwise, the plug can still be inserted normally, thereby improving the user experience.

[0185] In order to provide users with a better experience when inserting a plug and to take into account the effect of preventing single-pole insertion, the inclination of the second surface 215 and the third surface 216 can be set so that the clockwise rotation angle of the first protection door 20 is between 0-5°.

[0186] Alternatively, the first surface 214, the second surface 215, the third surface 216 and the fourth surface 217 may all be inclined, such as Figure 10 and Figure 11 In this way, when the first blocking portion 212 is subjected to a large force, and the second blocking portion 213 is subjected to a large force, the possibility that the first protection door 20 cannot be opened normally can be reduced.

[0187] In addition, guide grooves are provided in the middle of the second surface 215 and the fourth surface 217, and the bottom of the guide grooves is inclined. When a plug is inserted into the first socket 114, the plug can apply force to the first protective door 20 through the guide grooves, which can facilitate insertion and drive the first protective door 20 to slide.

[0188] In some embodiments, such as Figure 2 、 Figures 5 to 8 shown, the second protection door 30 includes a driving arm 32, a first blocking block 33 and a second blocking block 34. The first blocking block 33 and the second blocking block 34 are respectively connected to both sides of the driving arm 32, and a second mounting hole 301 is provided on the driving arm 32. The second jack 115 includes a first sub-slot, a second sub-slot and a third sub-slot. When the second protection door 30 shields the second jack 115, the part of the driving arm 32 where the second mounting hole 301 is not provided shields the first sub-slot, the first blocking block 33 shields the second sub-slot, and the second blocking block 34 shields the third sub-slot.

[0189] In the embodiments of the present application, the second jack 115 is a three-pin jack, including a first sub-slot, a second sub-slot and a third sub-slot.

[0190] Correspondingly, the first protection door 20 is a three-pin protection door, including a driving arm 32 that can shield the first sub-slot, a first blocking block 33 that can shield the second sub-slot, and a second blocking block 34 that can shield the third sub-slot. Therefore, the second protection door 30 can protect the second jack 115 when no plug is inserted into the second jack 115.

[0191] Such as Figure 2 、 Figure 8 and Figure 12 shown, a boss 118 is provided on the bottom 111 of the cavity, and a mounting groove 321 is provided on the side of the driving arm 32 facing the bottom 111 of the cavity. The boss 118 is slidably sleeved in the mounting groove 321.

[0192] In this way, the driving arm 32 can cooperate with the boss 118 on the bottom 111 of the cavity through the mounting groove 321, so that the second protection door 30 can slide relative to the bottom 111 of the cavity.

[0193] Thus, when a plug is inserted into the second jack 115, the driving arm 32 can drive the first blocking block 33 and the second blocking block 34 to slide synchronously to expose the first sub-slot, the second sub-slot and the third sub-slot for the plug to be inserted.

[0194] It should be noted that the aforementioned driving part 31 can be formed on the side of the driving arm 32 facing the connecting part 211.

[0195] In some embodiments, such as Figure 1 、 Figures 9 to 11 shown, a clamping member 23 is provided on the side of the first protection door 20 facing the bottom 111 of the cavity, and a cooperating member 116 is provided on the boss 118. The clamping member 23 cooperates with the cooperating member 116.

[0196] In this way, both the first protection door 20 and the second protection door 30 can be slidably connected to the housing 10 through the boss 118. As a common part of the first protection door 20 and the second protection door 30, the boss 118 makes the structure of the protection door structure 100 simple and convenient for assembly on the one hand.

[0197] On the other hand, it can also make the connection layout of the first protection door 20 and the second protection door 30 reasonable and occupy less space, and can reduce the possibility of setting multiple structures to cooperate with the first protection door 20 and the second protection door 30 respectively and increasing the occupied space.

[0198] The boss 118 is arranged on the cavity bottom 111. The boss 118 has a top surface facing away from the cavity bottom 111 and two side surfaces between the top surface and the cavity bottom 111.

[0199] In the embodiment of the present application, a fitting 116, such as a groove 1161 or a clamping protrusion 231, can be arranged on the top surface of the boss 118 to realize the cooperation between the boss 118 and the first protection door 20.

[0200] The second protection door 30 cooperates with the two side surfaces and the top surface of the boss 118 through the installation groove 321, so that both the first protection door 20 and the second protection door 30 can slide independently, and the possibility that the sliding of the first protection door 20 and the second protection door 30 is interfered by the other can be reduced.

[0201] In the embodiment of the present application, since a part of the second protection door 30 close to the first cavity wall 112 is nested with the first protection door 20, therefore, the first protection door 20 and the second protection door 30 are partially overlapped, which can make the space occupied by the first protection door 20 and the second protection door 30 in the first direction X smaller.

[0202] In this way, the size of the housing 10 and the installation cavity 11 in the first direction X can be made smaller, the overall volume of the protection door structure 100 can be reduced, and thus the manufacturing cost of the protection door structure 100 can be reduced.

[0203] Finally, it should be noted that the above embodiments are only specific implementation manners of the present application, but the protection scope of the present application is not limited thereto. Any changes or substitutions within the technical scope disclosed in the present application should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
