[0046] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are part of the embodiments of this application, not all of them. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of this application.

[0047] In addition, the technical features involved in the different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0048] An embodiment of the present application provides a protective door assembly, which is used for a socket. Figure 1 The structure and components of the protective door assembly are shown. Figure 1 As shown, the protective door assembly includes a base 1, an elastic member 2, a first protective door 3, and a second protective door 4. The base 1 has an inner cavity 11, within which a first partition 122 and a second partition 123 are spaced apart along a predetermined direction. The first partition 122 and the second partition 123 divide the inner cavity 11 into a first chamber 111 and a second chamber 112. The elastic member 2 is located in a first compartment 121 between the first partition 122 and the second partition 123. The first protective door 3 is located in the first chamber 111 and is movably engaged with the side of the first partition 122 facing the first chamber 111. The first protective door 3 has a first mounting arm 31 that extends into the first compartment 121. The second protective door 4 is located in the second chamber 112 and is movably engaged with the side of the second partition 123 facing the second chamber 112. The second protective door 4 has a second mounting arm 41 that extends into the first compartment 121. The first partition 122 , the first mounting arm 31 , the elastic member 2 , the second mounting arm 41 and the second partition 123 are arranged in sequence along a preset direction, and the preset direction is perpendicular to the opening direction of the seat 1 .

[0049] In the protective door assembly provided in the embodiment of the present application, the inner cavity 11 of the seat 1 is divided into two chambers by the first partition 122 and the second partition 123, and the first protective door 3 and the second protective door 4 are respectively arranged in the two chambers, and the first protective door 3 and the second protective door 4 are movably engaged with the side walls of the first partition 122 and the side walls of the second partition 123, respectively, for installation and positioning; at the same time, the elastic member 2 elastically abuts against the first mounting arm 31 of the first protective door 3 and the second mounting arm 41 of the second protective door 4, respectively, to achieve automatic reset of the first protective door 3 and the second protective door 4 after displacement. Therefore, the protective door assembly provided in the embodiment of the present application is not equipped with a seat cover, but the first protective door 3 and the second protective door 4 are directly engaged with the seat 1, thereby reducing the number of assembly parts, simplifying the structure and assembly process of the protective door assembly, reducing costs, and reducing the probability of product defects.

[0050] In order to make the technical solutions and advantages of this application clearer, Figure 1-5 , further introduces and illustrates a protective door assembly provided in an embodiment of the present application.

[0051] like Figure 1 As shown, in the protective door assembly provided by the embodiments of the present application, a cavity 11 is formed on one side of the base 1 for mounting the elastic member 2, the first protective door 3, and the second protective door 4. Cavity 11 is open, with the open end of the cavity facing the bottom plate 13 of the base 1. In some embodiments, the base 1 can also be referred to as a socket holder, meaning that the other side of the base 1 is used to mount the socket of the socket, thereby improving the structural compactness and integration of the base 1 and the socket.

[0052] The inner cavity 11 of the seat 1 is divided into a first chamber 111 and a second chamber 112 by a partition component 12, wherein the partition component 12 includes a first partition 122 and a second partition 123 arranged along a preset direction, and a first partition 121 is provided between the first partition 122 and the second partition 123. The first chamber 111 and the second chamber 112 are connected through the first partition 121, and the first protective door 3 and the second protective door 4 are respectively installed and accommodated in the first chamber 111 and the second chamber 112.

[0053] The elastic member 2 is arranged in the first space 121 and is always in an elastically compressed state. When in the elastically compressed state, the elastic force provided by the elastic member 2 is directed away from the center of the elastic member 2. Optionally, the elastic member 2 is a compression spring.

[0054] Optionally, the first protection door 3 and the second protection door 4 are a two-pole protection door and a three-pole protection door, respectively. The two-pole protection door is used to shield the two-pole jack on the socket when it is not in use; the three-pole protection door is used to shield the three-pole jack on the socket when it is not in use. For example, the first protection door 3 is a two-pole protection door, and the second protection door 4 is a three-pole protection door. Therefore, the protection door assembly is a five-pole protection door assembly.

[0055] A first mounting arm 31 and a first engaging portion 32 are provided on the side wall of the first protective door 3 near the first partition 122. The first engaging portion 32 extends less than the first mounting arm 31 from the side wall. The first engaging portion 32 corresponds to the side wall of the first partition 122. A first guide portion 124 is provided on the side wall of the first partition 122 facing the first chamber 111. The first guide portion 124 movably engages with the first engaging portion 32, allowing the first engaging portion 32 and the first protective door 3 to move relative to the first guide portion 124 and the first partition 122. A portion of the first mounting arm 31 extends into the first compartment 121 and elastically abuts against the elastic member 2 located within the first compartment 121. Since the elastic member 2 is always in an elastically deformed state, when the first protective door 3 is not subjected to external force, the side of the first mounting arm 31 away from the elastic member 2 will be offset against the first partition 122 under the elastic force of the elastic member 2, that is, the first mounting arm 31 is elastically limited between the elastic member 2 and the first partition 122.

[0056] A second mounting arm 41 and a second engaging portion 42 are provided on the side wall of the second protective door 4 near the second partition 123. The second engaging portion 42 extends less than the second mounting arm 41 from the side wall. The second engaging portion 42 corresponds to the side wall of the second partition 123. A second guide portion 125 is provided on the side wall of the second partition 123 facing the second chamber 112. This second guide portion 125 movably engages with the second engaging portion 42, allowing the second engaging portion 42 and the second protective door 4 to move relative to the second guide portion 125 and the second partition 123. A portion of the second mounting arm 41 extends into the first compartment 121 and elastically abuts against the elastic member 2 located within the first compartment 121. Since the elastic member 2 is always in an elastically deformed state, when the second protective door 4 is not subjected to external force, the side of the second mounting arm 41 away from the elastic member 2 will be offset against the second partition 123 under the elastic force of the elastic member 2, that is, the second mounting arm 41 is elastically limited between the elastic member 2 and the second partition 123.

[0057] like Figure 1 and Figure 2As shown, the base 1 includes a base plate 13 and an annular enclosure 14. The annular enclosure 14 is connected to the edge of the base plate 13 along the circumference of the base plate 13, so that the base plate 13 and the annular enclosure 14 cooperate to form the inner cavity 11 of the base 1. As described above, the first protective door 3 is a two-pole protective door, and the second protective door 4 is a three-pole protective door. Accordingly, the portion of the base plate 13 located in the first chamber 111 has three sockets, namely the L-pole socket and the N-pole socket in the two-pole socket, and the E-pole socket in the three-pole socket; the portion of the base plate 13 located in the second chamber 112 has two oblique sockets, namely the L-pole socket and the N-pole socket in the three-pole socket. The plug pin passes through the sockets on the protective door assembly and the base plate 13, and is plugged into and mated with the socket located on the side of the base plate 13 facing away from the protective door assembly.

[0058] like Figure 4 As shown, the bottom plate 13 is also provided with a plurality of protrusions, located on the sides of each insertion hole, which serve as a limiter or guide. The limiter function refers to the fact that when the bolt is inserted in a single position, the protrusions abut against the first protective door 3 or the second protective door 4, thereby preventing the first protective door 3 or the second protective door 4 from shifting and exposing the insertion hole. The guide function refers to the fact that the protrusions cooperate with the inserted bolt and guide the bolt vertically into the corresponding insertion hole.

[0059] In some embodiments of the present application, at least one of the first guide portion 124 and the second guide portion 125 is a protrusion protruding from the sidewall of the first partition 122 or the second partition 123 to which it is connected. The protrusion has a guide surface 51 extending toward the bottom plate 13 and toward the first gap 121. A second gap 52 is defined between the guide surface 51 and the bottom plate 13. After the first engaging portion 32 or the second engaging portion 42 engages with the corresponding protrusion, the first engaging portion 32 or the second engaging portion 42 is located within the second gap 52 and can reciprocate within the second gap 52 along the extension direction of the guide surface 51. Optionally, at least one of the first engaging portion 32 and the second engaging portion 42 is a block.

[0060] In this way, the first protective door 3 and the second protective door 4 can be directly snapped into the first chamber 111 and the second chamber 112, and are not easy to fall off, so there is no need to use an additional seat 1 cover to install and fix the first protective door 3 and the second protective door 4, thereby reducing the number of parts of the protective door assembly and simplifying the assembly process of the protective door assembly.

[0061] Alternatively, as Figure 2 As shown, the side of the guide surface 51 away from the second gap 52 is connected to the annular enclosure 14, that is, the first guide portion 124 and / or the second guide portion 125 are connected to the enclosure. Therefore, the first engaging portion 32 is unlikely to fall out of the second gap 52 during movement relative to the guide surface 51, ensuring reliable assembly of the first and second protection doors 3 and 4.

[0062] In some embodiments of this application, see Figure 2 and Figure 3 The protrusion further has an assembly surface 53, which is disposed opposite the guide surface 51 in the direction of the opening of the seat 1. At least a portion of the assembly surface 53 is an inclined surface, the starting point of which is generally the overhanging side 54 of the protrusion. The overhanging side 54 refers to the side of the protrusion away from the first separator 122 or the second separator 123 to which it is connected. The inclined surface inclines in a direction such that the closer it is to the overhanging side 54, the closer it is to the base plate 13.

[0063] By assembling the first protective door 3 and the second protective door 4 in a snap-fit ​​manner and setting the distant portion of the assembly surface 53 as an inclined surface, the assembly of the first protective door 3 and the second protective door 4 is facilitated. During operation, it is only necessary to press the first protective door 3 and the second protective door 4 vertically, which is conducive to the realization of automated equipment assembly, improves production efficiency, and effectively reduces production costs and assembly costs, thereby realizing lean production.

[0064] In some embodiments of the present application, Figure 1 As shown, to prevent the first protective door 3 from escaping from the first chamber 111 due to tilting during movement, the annular enclosure 14 is provided with a third guide portion 141 on the side of the first chamber 111 away from the partition assembly 12. The first protective door 3 is provided with a third engaging portion 33 on the side away from the partition assembly 12. The third engaging portion 33 is movably engaged with the third guide portion 141, wherein the centerline of the first protective door 3 passes through the third engaging portion 33. Optionally, the third guide portion 141 is positioned opposite the first compartment 121, and the axis of the first compartment 121 passes through the third guide portion 141.

[0065] Similarly, if Figure 1 As shown, to prevent the second protective door 4 from skewing and falling out of the second chamber 112 during movement, the annular enclosure 14 is provided with a fourth guide portion 142 on the side of the second chamber 112 away from the partition assembly 12. The second protective door 4 is provided with a fourth engaging portion 43 on the side away from the partition assembly 12. The fourth engaging portion 43 is movably engaged with the fourth guide portion 142, wherein the centerline of the second protective door 4 passes through the fourth engaging portion 43. Optionally, the fourth guide portion 142 is positioned opposite the first compartment 121, and the axis of the first compartment 121 passes through the fourth guide portion 142.

[0066] In this way, the first protective door 3 and the second protective door 4 are snap-fitted to the seat 1 on opposite sides, which improves assembly efficiency and reduces assembly costs while ensuring assembly reliability and reducing product defect rates.

[0067] Alternatively, as Figure 1As shown, the first mounting arm 31 is located on one side of the center line of the first protective door 3, and the first clamping portion 32 is located on the side of the first mounting arm 31 away from the center line of the first protective door 3; the second mounting arm 41 is located on one side of the center line of the second protective door 4, and the second clamping portion 42 is located on the side of the second mounting arm 41 away from the center line of the second protective door 4.

[0068] By arranging the first mounting arm 31 and the first clamping portion 32 on the first protective door 3 on the same side of the center line of the first protective door 3, and arranging the second mounting arm 41 and the second clamping portion 42 on the second protective door 4 on the same side of the center line of the second protective door 4, it is convenient to reduce the assembly identification action of the first protective door 3 or the second protective door 4, which is conducive to improving the assembly efficiency.

[0069] like Figure 3 As shown, the portion of the base plate 13 located within the first cavity 111 is provided with a first opening 131. The first partition 122 is connected to a side edge of the first opening 131. The orthographic projection of at least a portion of the first guide portion 124 on the base plate 13 is located within the first opening 131. The seat 1 provided in this embodiment of the application is an integrally molded structure, for example, by injection molding, wherein a portion of the mold passes through the first opening 131 to form the first guide portion 124.

[0070] However, the structural strength of the bottom plate 13 at the edge of the first opening 131 is relatively poor. To improve this problem, in some embodiments of the present application, such as Figure 3 As shown, the first opening 131 is provided with a first rib 133 near the edge of the first compartment 121, and one end of the first rib 133 is connected to the first partition 122; Figure 5 As shown, the other end of the first rib 133 is in contact with the first protection door 3 or has a gap therebetween.

[0071] The provision of the first rib 133 enhances the structural strength and rigidity at the edge of the first opening 131, thereby improving the service life of the seat 1. Furthermore, the first rib 133 cooperates with the side wall of the first protective door 3 near the first partition 122 to limit the position of the first protective door 3 and guide it during movement.

[0072] Optionally, continue with Figure 3 The bottom plate 13 is further provided with a first stopper 135, which is located in the first chamber 111 and connected to the second partition 123. The first stopper 135 is used to limit the first protective door 3 and guide the first protective door 3 during its movement.

[0073] The distance between the end surface of the first stopper 135 away from the second partition 123 and the second partition 123 is equal to the distance between the end surface of the first rib 133 away from the first partition 122 and the first partition 122. In other words, the end surface of the first stopper 135 away from the second partition 123 and the end surface of the first rib 133 away from the second partition 123 are arranged side by side along the arrangement direction of the first partition 122 and the second partition 123. Therefore, the two cooperate with each other to constrain the movement direction of the first protective door 3.

[0074] It is easy to understand that when the first rib 133 or the first stopper 135 contacts the first protective door 3, it will cause resistance to the movement of the first protective door 3. Therefore, generally speaking, there is a gap between the first rib 133 and the first stopper 135 and the first protective door 3.

[0075] like Figure 4 As shown, the portion of the bottom plate 13 located within the second cavity 112 is provided with a second opening 132. The second partition 123 is connected to a side edge of the second opening 132. The orthographic projection of at least a portion of the second guide portion 125 on the bottom plate 13 is located within the second opening 132. The seat 1 provided in this embodiment of the application is an integrally molded structure, for example, by injection molding, wherein a portion of the mold extends through the second opening 132 to form the second guide portion 125.

[0076] However, the structural strength of the bottom plate 13 at the edge of the second opening 132 is relatively poor. To improve this problem, in some embodiments of the present application, such as Figure 4 As shown, the second opening 132 is provided with a second rib 134 near the edge of the first compartment 121, and one end of the second rib 134 is connected to the second partition 123; Figure 5 As shown, the other end of the second rib 134 contacts the second protection door 4 or has a gap therebetween.

[0077] The provision of the second rib 134 increases the structural strength and rigidity at the edge of the second opening 132, thereby improving the service life of the seat 1. Furthermore, the second rib 134 cooperates with the side wall of the second protective door 4 near the second partition 123 to limit the position of the second protective door 4 and guide it during movement.

[0078] Optionally, continue with Figure 4 The bottom plate 13 is further provided with a second stopper 136, which is located in the second chamber 112 and connected to the first partition 122. The second stopper 136 is used to limit the second protection door 4 and guide the second protection door 4 during its movement.

[0079] The distance between the end surface of the second stopper 136 away from the first partition 122 and the first partition 122 is equal to the distance between the end surface of the second rib 134 away from the second partition 123 and the second partition 123. In other words, the end surface of the second stopper 136 away from the first partition 122 and the end surface of the second rib 134 away from the first partition 122 are arranged side by side along the arrangement direction of the first and second partitions 122, 123. Therefore, the two cooperate with each other to constrain the movement direction of the second protective door 4.

[0080] It is easy to understand that when the second rib 134 or the second stopper 136 contacts the second protection door 4, it will cause resistance to the movement of the second protection door 4. Therefore, generally speaking, there is a gap between the second rib 134 and the second stopper 136 and the second protection door 4.

[0081] The protective door assembly provided in the embodiment of the present application can realize automated equipment assembly. The assembly process can be, for example: first, the first protective door 3 and the second protective door 4 are grabbed by a robot arm, and they are assembled from top to bottom into the first chamber 111 and the second chamber 112 of the seat 1 respectively.
