[0040] <Protective door structure>

[0041] See also Figures 1 to 5 , Figure 1 An exploded view of a protective door structure 100 according to an embodiment of the present invention is shown. Figure 2 A partial exploded view of a protective door structure 100 according to an embodiment of the present invention is shown. Figure 3 The structure diagram of the protection door 6 of the protection door structure 100 according to one embodiment of the utility model is shown. Figure 4 The figure shows an assembly perspective view of a protective door structure 100 according to an embodiment of the present invention. Figure 5 Shows from Figure 4 An assembled stereoscopic view of a protective door structure 100 according to an embodiment of the present invention is observed at the AA section.

[0042] like Figure 1 As shown, the protection door structure 100 includes a socket inner core seat 5 , a protection door 6 and an elastic member 7 .

[0043] like Figures 1 to 5As shown, the protection door 6 has a first assembly portion 61 and at least one pair of plug-in columns arranged opposite to each other, one end of the plug-in column is connected to the lower surface 611 of the first assembly portion 61, and the other end is formed with a protrusion. In addition, the plug-in core seat 5 includes a second assembly portion opposite to the first assembly portion 61 of the protection door 6, and a limiting groove 51 is arranged on the second assembly portion. The limiting groove 51 has two step portions 513 and 514. The two step portions 513 and 514 are located at the notch of the limiting groove 51 and are arranged corresponding to the at least one pair of plug-in columns. When the protection door 6 is installed on the plug-in core seat 5, the plug-in column is inserted into the limiting groove 51, and the protrusion is clamped on the step portion.

[0044] Therefore, by inserting the plug-in column of the protective door 6 into the limiting groove 51 of the integrally formed plug-in core seat 5 and snapping it into the limiting groove 51, the protective door 6 will not fall off the plug-in core seat 5 even if there is no outer shell or other components to support it. The overall operation is convenient, the installation is simple, and the cost is low.

[0045] More specifically, in some embodiments, the protective door 6 has a first assembly portion 61 and a first plug-in column 621 and a second plug-in column 622 that are arranged oppositely. One end of the first plug-in column 621 is connected to the lower surface 611 of the first assembly portion 61, and the other end is formed with a first protrusion 621a. One end of the second plug-in column 622 is connected to the lower surface 611 of the first assembly portion 61, and the other end is formed with a second protrusion 622a. Here, the first plug-in column 621 and the second plug-in column 622 are sometimes collectively referred to as plug-in columns, and the first protrusion 621a and the second protrusion 622a are collectively referred to as protrusions. In addition, a pair of plug-in columns, namely the first plug-in column 621 and the second plug-in column 622, are listed here, but it is not limited to this, and it can be multiple pairs, such as two pairs of plug-in columns arranged oppositely. The plug-in column can be made of a flexible material that can be elastically deformed, such as plastic, to increase the flexibility and service life of the plug-in column.

[0046] In addition, the plug-in core seat 5 includes a second assembly portion for mounting the first assembly portion 61 of the protective door 6. The limiting groove 51 is arranged at a position approximately in the middle of the second assembly portion. When the plug-in core seat 5 is viewed from the first direction D1, the limiting groove 51 is formed into a rectangle along the third direction D3. The first step portion 513 and the second step portion 514 are respectively arranged near the notch of the two inner groove walls of the limiting groove 51 along the third direction D3, namely the first inner groove wall 51a and the second inner groove wall 51b. The first step portion 513 corresponds to the first plug-in column 621, and the second step portion 514 corresponds to the second plug-in column 622. In addition, the first direction D1 shown in each figure refers to the height direction of the plug-in core seat 5, the second direction D2 is the width direction of the plug-in core seat 5 perpendicular to the first direction D1, and the third direction D3 is the length direction of the plug-in core seat 5 perpendicular to both the first direction D1 and the second direction D2.

[0047] In addition, the first step portion 513 includes a first step portion side surface 513a and a first step portion bottom surface 513b, the first step portion side surface 513a is connected to the first inner groove wall 51a through the first step portion bottom surface 513b, and protrudes into the limiting groove 51 relative to the first inner groove wall 51a. Similarly, the second step portion 514 includes a second step portion side surface 514a and a second step portion bottom surface 514b, the second step portion side surface 514a is connected to the second inner groove wall 51b through the second step portion bottom surface 514b, and protrudes into the limiting groove 51 relative to the second inner groove wall 51b. In addition, the distance between the two step portions is smaller than the distance between the two opposite inner groove walls, specifically, the distance between the first step portion side surface 513a and the second step portion side surface 514a is smaller than the distance between the first inner groove wall 51a and the second inner groove wall 51b.

[0048] In the present invention, the limiting groove 51 is formed as a through hole groove, but it is not limited thereto. In some embodiments, the limiting groove 51 can also be formed as a blind hole groove. In addition, the limiting groove 51 also includes a rear groove wall 511 and a second positioning protrusion 512 protruding from the rear groove wall 511 and a receiving groove 56 located on the front groove wall opposite to the rear groove wall 511. The rear groove wall 511 and the front groove wall are respectively connected to the two inner groove walls of the limiting groove 51.

[0049] When the protection door 6 is installed on the inner core seat 5 of the socket, as the first plug-in column 621 and the second plug-in column 622 are inserted into the limiting groove 51, the first protrusion 621a and the second protrusion 622a respectively abut against the first step portion side 513a and the second step portion side 514a while being inserted downward, so that the first plug-in column 621 and the second plug-in column 622 undergo elastic deformation and bend slightly toward the inside of the limiting groove 51. After the first protrusion 621a and the second protrusion 622a pass through the first step portion 513 and the second step portion 514 in the limiting groove 51, the first plug-in column 621 and the second plug-in column 622 open to the outside of the limiting groove 51, so that the first protrusion 621a and the second protrusion 622a can be respectively clamped on the bottom surface 513b of the first step portion and the bottom surface 514b of the second step portion.

[0050] In addition, the protrusion in the above structure is formed into a barb shape that is inclined from the top of the other end of the plug-in column toward the bottom that is engaged with the step portion. More specifically, the first protrusion 621a is formed into a barb shape that is inclined from the first top 621b of the first plug-in column 621 toward the first bottom 621c that is engaged with the first step portion 513. In addition, the second protrusion 622a is formed into a barb shape that is inclined from the second top 622b of the second plug-in column 622 toward the second bottom 622c that is engaged with the second step portion 514. By forming the protrusion into a barb shape, the plug-in column can be smoothly inserted into the limiting groove, and can be reliably engaged with the step portion so that the protective door is not easy to fall off.

[0051] In addition, the first assembly part 61 of the protection door 6 has an upper surface 612 and a lower surface 611, and the upper surface 612 is formed as an inclined surface having a predetermined angle relative to the lower surface 611. In addition, assuming that the height of the rear side 616 of the first assembly part is h, the height h of the rear side 616 of the first assembly part 61 is greater than the height of the front side 615 of the first assembly part 61. In some embodiments, the front side 615 of the first assembly part 61 can be an edge where the upper surface 612 and the lower surface 611 intersect, or can be a side with a certain height between the upper surface 612 and the lower surface 611, as long as the height h of the rear side 616 of the first assembly part 61 is greater than the height of the front side 615 of the first assembly part.

[0052] In addition, the second assembly portion of the plug-in core seat 5 further includes a groove 52, and at least a portion of the protection door 6 is installed in the groove 52. More specifically, as Figures 1 to 5 As shown, a groove 52 is formed at the top of the plug-in core seat 5, and the groove 52 has a depth H along the first direction D1, including a front end 54 and two side ends 55 connecting the front end 54. When the protection door 6 is installed on the plug-in core seat 5, the front side 615 of the first assembly part of the protection door 6 is abutted against the front end 54 of the groove 52. In addition, the width of the first assembly part 61 of the protection door 6 along the second direction D2 is smaller than the width of the groove 52 of the plug-in core seat 5 along the second direction D2, that is, smaller than the distance between the two side ends 55 of the groove 52. In addition, in some embodiments, the depth H of the groove 52 of the plug-in core seat 5 is greater than or equal to the height h of the first assembly part 61 of the protection door 6.

[0053] Thus, by providing the groove 52 on the socket inner core seat 5 and making the depth H of the groove 52 greater than or equal to the height h of the protection door 6, the height of the socket inner core seat 5 can be effectively reduced. In addition, by making the front side 615 of the first assembly portion 61 of the protection door 6 abut against the front end portion 54 of the groove 52, when the plug 1 is inserted, the L / N pole plug 122 of the plug 1 contacts the inclined surface, so that the L / N pole plug 122 is smoothly inserted while the protection door 6 slides away from the front end portion 54 of the groove 52.

[0054] More specifically, the protection door 6 can slide relative to the socket inner core seat 5 in the limiting groove 51. In addition, when the plug pin 122 of the plug 1 is not inserted, the protection door 6 is in a protective state and covers the insertion hole 53 of the socket inner core seat 5. When the plug pin 111 is inserted, the protection door 6 is in a non-protective state and is away from the insertion hole 53 of the socket inner core seat 5.

[0055] The above-mentioned protection state refers to the state in which the protection door 6 covers the insertion hole 53 of the plug-in core seat 5 so that the insertion hole 53 is not exposed. Preferably, in the protection state, the front end 615 of the first assembly part of the protection door 6 abuts against the front end side 54 of the groove 52 of the plug-in core seat 5, and the rear end 616 of the first assembly part is located at a position that can cover the insertion hole 53 of the plug-in core seat 5. That is, in order to cover the entire insertion hole 53, the length of the protection door 6 along the third direction D3 is greater than the sum of the length of the insertion hole 53 along the third direction D3 and the distance from the insertion hole 53 (the side of the insertion hole closest to the front end side 54) to the front end side 54 of the groove 52. In addition, the width of the protection door 6 along the second direction D2 is also greater than the distance between the two insertion holes 53, that is, greater than the distance between the two sides of the two insertion holes 53 closest to the two end sides 55 of the groove 52.

[0056] The non-protective state refers to a state in which the protective door 6 does not cover the insertion hole 53 of the socket inner core seat 5 when it moves toward the front end side 54 away from the groove 52, or only partially covers the insertion hole 53, that is, the insertion hole 53 is completely or partially exposed.

[0057] In addition, if Figures 1 to 5 As shown, the protection door device 100 of the present invention further includes an elastic member 7. The elastic member 7 may be, for example, a spring. The elastic member 7 is installed in the limiting groove 51, one end of the elastic member 7 is installed on the rear groove wall 511 of the limiting groove 51, and the other end abuts against the protection door 6. The elastic member 7 is deformed when the protection door 6 slides from the protection state to the non-protection state, and the protection door 6 slides from the non-protection state to the protection state when the elastic member 7 is restored.

[0058] In some embodiments, the protective door 6 may include two door panels, namely a first door panel 613 and a second door panel 614. In the protective state, the first door panel 613 and the second door panel 614 can respectively cover their corresponding sockets 53 so that the sockets 53 are not exposed, and in the non-protective state, the sockets 53 can be fully or partially exposed.

[0059] In addition, a recess 63 with one end open is provided between the first door piece 613 and the second door piece 614, and the recess 63 has a first side wall 631 and a second side wall 632 opposite to each other, and an inner wall 633 connecting the first side wall 631 and the second side wall 632. In addition, the first plug-in column 621 of the protection door 6 extends from the first side wall 631 of the recess 63, and the second plug-in column 622 extends from the second side wall 632 of the recess 63.

[0060] In addition, a first positioning boss 634 is provided on the inner wall 633 of the recess 63, a second positioning boss 512 is provided on the rear groove wall 511 of the limiting groove 51, one end of the elastic member 7 is sleeved on the second positioning boss 512, and the other end of the elastic member 7 is sleeved on the first positioning boss 634 arranged opposite to the second positioning boss 634. In some embodiments, when assembling the protection door structure 100, the front side 615 of the first assembly portion of the protection door 6 is abutted against the front end portion 54 of the groove 52, and the first positioning boss of the protection door 6 is partially received in the receiving groove 56 of the limiting groove 51, so that the first positioning boss 634 and the second positioning boss 512 can be coaxially arranged in the third direction D3.

[0061] The above is a description of the protection door structure 100 of the present invention. According to the above structure, the protection door can be prevented from falling off, and the thickness of the protection door structure can be reduced, the overall operation is convenient, the installation is simple, and the cost is low.

[0062] Next, a socket device to which the protective door structure 100 is applied will be described.

[0063] <Socket device>

[0064] Figures 6 to 9 The working principle of the plug 1 being inserted into the socket 13 to which the protective door structure 100 is applied is shown. Figure 6 A side view of a plug 1 to be inserted into a socket 13 according to an embodiment of the present invention is shown. Figure 7 A side view showing the plug 1 ready to be inserted into the socket 13 of one embodiment of the present invention. Figure 8 A side view showing a plug 1 being inserted into a socket 13 according to an embodiment of the present invention is shown. Fig. 9 The side view of the plug 1 fully inserted into the socket 13 of one embodiment of the present invention is shown. In the present invention, the socket 13 is listed as a socket device, but it is not limited to a single socket device, and can also be a socket device with multiple sockets.

[0065] like Figure 6 As shown, the plug 1 is not inserted into the socket 13, and the front side 615 of the first assembly portion of the protection door 6 abuts against the front end portion 54 of the groove 52 and is in a protective state. At this time, the elastic member 7 is in an initial state.

[0066] Then, if Figure 7 As shown, the plug 1 is about to be inserted into the socket 13, and one end of the L / N pole pin 122 of the plug 1 contacts the upper surface 612 of the protection door 6, but the protection door 6 remains unchanged at this time, and the front side 615 of the first assembly part of the protection door 6 is still in contact with the front end part 54 of the groove 52 and is in a protective state. At this time, the elastic member 7 is still in the initial state.

[0067] Then, if Figure 8 As shown, the plug 1 is inserted downward into the socket 13 to a certain position, and the L / N pole pin 122 of the plug pushes downward the inclined surface of the upper surface 612 of the protective door 6 when inserted, so that the protective door 6 gradually slides to the left until the L / N pole pin 122 of the plug 1 passes through the protective door 6 and is inserted into the socket 53. At the same time, the elastic member 7 is deformed and compressed. At this time, the front side 615 of the first assembly portion of the protective door 6 abuts against the L / N pole pin 122 under the action of the elastic member 7.

[0068] Then, if Fig. 9 As shown, the plug 1 continues to be inserted downward into the socket 13 until it is fully inserted. During this process, the elastic member 7 is deformed and compressed, and the front side 615 of the first assembly portion of the protective door 6 is always in contact with the L / N pole pin 122 under the action of the elastic member 7.

[0069] The working principle of the plug inserted into the socket 13 using the above-mentioned protection door structure 100 is described above. When the plug is to be pulled out of the socket 13 using the above-mentioned protection door structure 100, although not shown in the figure, when the plug 1 is to be pulled out of the socket 13, the elastic member 7 is in a compressed state, and the front side 615 of the first assembly portion of the protection door 6 is always in contact with the L / N pole plug pin 122 under the action of the elastic member 7.

[0070] When the plug 1 is pulled out of the socket 13 upward to a certain position, the elastic member 7 is in a compressed state, similar to when the plug 1 is about to be pulled out of the socket 13 , and the front side 615 of the first assembly portion of the protective door 6 is always in contact with the L / N pole pin 122 under the action of the elastic member 7 .

[0071] When the plug 1 continues to be pulled out of the socket 13 upward until it is completely disengaged, during this process, when the L / N pole pin 122 of the plug 1 is pulled out upward, the pin 122 of the plug 1 disengages from the protective door 6, and the protective door 6 gradually slides to the right. At the same time, the compression force of the elastic member 7 is released, so that the protective door slides to the right to its original position, that is, the front side 615 of the first assembly portion of the protective door 6 abuts against the front end portion 54 of the groove 52 and is in a protective state.

[0072] According to the socket device of the above structure, the overall height of the socket device can be reduced, and there is no need to use the housing of the socket device to support the protection door so that the protection door does not fall off, so the assembly cost is low.
