[0052] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described. Obviously, the described embodiments are only some of the embodiments of the present application, but not all of the embodiments of the present application. Based on the embodiments of the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts should fall within the scope of the present application.

[0053] 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 there is no conflict.

[0054] The embodiments of the present application provide a socket module, as shown in Figure 1 and Figure 2 The socket module includes a shell 1, a socket 2, a movable piece 3, a fixed piece 4, and two anti-disengagement pieces 5. The socket 2 is located inside the shell 1, and the shell 1 is provided with a first insertion hole 11 at a position corresponding to the socket 2. The socket 2 and the first insertion hole 11 are adapted to be inserted and matched with the plug pin. The movable piece 3 can reciprocate relative to the shell 1 along the axial direction of the first insertion hole 11. The fixed piece 4 is fixed inside the shell 1 and is inserted and matched with the movable piece 3. The upper end of the fixed piece 4 protrudes from the upper end of the movable piece 3, and the upper end is the end close to the first insertion hole 11. The two anti-disengagement pieces 5 are arranged at intervals to form an insertion gap 6 for the plug pin. Each anti-disengagement piece 5 has a first side 51 close to the other anti-disengagement piece 5 and a second side 52 away from the other anti-disengagement piece 5. For each anti-disengagement piece 5, the first side 51 is overlapped and matched with the movable piece 3, and the second side 52 is overlapped and matched with the fixed piece 4. Thus, the first side 51 of the anti-disengagement piece 5 can be rotated around the matching part of the second side 52 and the fixed piece 4 under the driving of the movable piece 3. When the movable piece 3 drives the two anti-disengagement pieces 5 to move away from the socket 2, the distance between the first sides 51 of the two anti-disengagement pieces 5 gradually decreases.

[0055] The socket module provided in the embodiment of the present application forms a plug-in path for the plug pin to be inserted between the first jack 11 of the housing 1 and the socket 2, and the plug-in path is provided with a plug-in gap 6 formed by two anti-slip parts 5 arranged at intervals. The first side 51 and the second side 52 of each anti-slip part 5 are respectively overlapped with the movable part 3 and the fixed part 4. The movable part 3 can move and drive the first side 51 of the two anti-slip parts 5 to rotate around the fitting point of the second side 52 and the fixed part 4. When the plug is inserted into the socket module, the plug pin of the plug passes through the first jack 11 and the plug-in gap 6 in sequence along the plug-in path and is inserted into the socket 2. At this time, if the plug is to be pulled out in the opposite direction, the movable part 3 will drive the first side 51 of the two anti-slip parts 5 to move away from the socket 2. In this case, the distance between the first sides 51 of the two anti-slip parts 5 will gradually decrease, that is, the size of the plug-in gap 6 will decrease, thereby tightly clamping the pin to prevent it from detaching from the socket 2. Therefore, the solution of the present application plays a role in preventing the plug connected to the socket module from loosening, thereby avoiding a series of adverse consequences caused by the accidental loosening of the plug.

[0056] In order to make the technical solutions and advantages of this application clearer, Figures 1-11 , further introduces and illustrates the socket module provided in the embodiment of the present application.

[0057] like Figure 1 As shown, the shell 1 of the socket module includes a base plate 13 and an upper shell 14, and the base plate 13 and the upper shell 14 are detachably connected, for example, by snaps or screws. After the base plate 13 and the upper shell 14 are snapped together, a receiving cavity is formed between the two for accommodating other components of the socket module. A first socket 11 is provided on the surface of the shell 1 for plugging in with the plug. The number and shape of the first sockets 11 are designed according to actual needs. For example, the number of first sockets 11 may be two, for plugging in and out with the two pins of a two-pole plug respectively; or, the number of first sockets 11 may be three, for plugging in and out with the three pins of a three-pole socket 2 respectively; or, the number of first sockets 11 may be five, of which two first sockets 11 correspond to the two pins of a two-pole plug respectively, and the other three first sockets 11 correspond to the three pins of a three-pole plug respectively; or, the number of first sockets 11 may also be other numbers. In an embodiment of the present application, as Figure 2 As shown, the number of the first jacks 11 is three for exemplary description.

[0058] In addition, in the related art, a single outlet module generally only adopts one type of output site. For example, in a PDU (Power Distribution Unit) of an IEC (International Electrotechnical Commission) standard outlet, the output site is generally a C13 interface or a C19 interface, resulting in poor layout flexibility of the outlet output site. In the embodiments of the present application, the first outlet 11 can be plugged with the pins of at least two types of plugs to meet the plugging requirements of different types of plugs, thereby improving the layout flexibility of the outlet output site. For example, as shown in Figure 2 the first outlet 11 corresponds to output site types including C13, C15 and C19, and is suitable for plugging with C14 plugs and C20 plugs.

[0059] The number of the bushings 2 in the outlet module is generally two or three. When the number is two, the bushings 2 are generally L-pole bushings 2 and N-pole bushings 2. When the number is three, the bushings 2 are generally L-pole bushings 2, N-pole bushings 2 and E-pole bushings 2. The bushings 2 are installed inside the housing 1, and the power connection end of each bushing 2 can be exposed to or protrude from the outside of the housing 1 to connect the corresponding bushing 2 to a circuit. As shown in Figure 1 each bushing 2 has a clamping gap 21 for contact with the pin, and the clamping gap 21 is formed by two conductive sheets, and the width of the clamping gap 21 is generally less than the thickness of the pin, so that when the pin is inserted into the clamping gap 21, the two conductive sheets are deformed to press the pin, thereby clamping the pin.

[0060] However, with the long-term use of the outlet module, each bushing 2 can be deformed due to repeated plugging and unplugging, thereby increasing the width of the clamping gap 21 and reducing the clamping force provided by the bushing 2, making it difficult to clamp the pin inserted therein, and the pin can easily come off. In this case, it is easy to cause unstable power connection of the electrical equipment, thereby causing data loss and even equipment damage and other serious consequences. In particular, in a data center room, it is necessary to ensure that the power plug of the server is reliably plugged, to prevent the server from being powered off due to the plug coming off.

[0061] Therefore, in the embodiments of the present application, two anti-disengagement pieces 5 are arranged between the first outlet 11 and the clamping gap 21 of at least one bushing 2, and a part of at least one anti-disengagement piece 5 is exposed from the first outlet 11. After the pin enters the first outlet 11, it first enters the plugging gap 6 between the two anti-disengagement pieces 5 and contacts the anti-disengagement pieces 5, and then enters the clamping gap 21 of the bushing 2.

[0062] Wherein, after the insertion of the plug pin into the insertion gap 6, the interaction force between the two anti-dropping pieces 5 and the plug pin is that they abut against each other, thus the two anti-dropping pieces 5 will exert additional clamping force on the plug pin to prevent the plug pin from exiting the clamping gap 21 of the socket 2 and the first insertion hole 11, thereby preventing the plug from being loosened from the socket module. Generally, the anti-dropping pieces 5 are arranged in pairs, and the number and arrangement position of the anti-dropping pieces 5 acting on the same plug can be set according to requirements. Generally, since the plug pins on the same plug are fixedly connected through the plug shell, as long as one of the plug pins is clamped when the plug is inserted into the socket 2, the plug and the socket module will basically not be loosened. Therefore, in the embodiments of the present application, as shown in Figure 1 , for the plurality of sockets 2 inserted into the same plug, only one pair of anti-dropping pieces 5 is arranged above one of the sockets 2. The embodiments of the present application take the socket 2 provided with the anti-dropping pieces 5 as an E-pole socket as an example, and hereinafter, unless otherwise specified, the "socket" refers to the E-pole socket.

[0063] The anti-dropping pieces 5 are installed inside the shell 1 through the movable piece 3 and the fixed piece 4, wherein the movable piece 3 is movably installed relative to the shell 1, and the fixed piece 4 is fixedly installed relative to the shell 1. At least a part of the anti-dropping pieces 5 can move due to the need of clamping or releasing the plug pin.

[0064] In some embodiments of the present application, as shown in Figure 3 and Figure 4 , the two anti-dropping pieces 5 are arranged in a spaced and symmetrical manner, and the insertion gap 6 includes a first gap 61 formed between a part of the two anti-dropping pieces 5, and a second gap 62 formed between another part of the two anti-dropping pieces 5, the first gap 61 is used to allow at least part of the plug pin of one type of plug to be inserted, and the second gap 62 is used to allow at least part of the plug pin of another type of plug to be inserted.

[0065] Wherein, the normal projection of the first gap 61 and the second gap 62 on the opening plane of the first insertion hole 11 coincides with or is located within the first insertion hole 11. In this way, the plug pin inserted into the first insertion hole 11 can pass through the first gap 61 and / or the second gap 62 to enter the clamping gap 21 of the socket 2.

[0066] Therefore, the first insertion hole 11, the first gap 61 and the second gap 62 between the two anti-dropping pieces 5, and the clamping gap 21 of the socket 2 cooperate to be compatible with at least two types of plug pins. In this way, when the socket module is applied to a PDU, flexible layout of the socket output positions can be achieved, thereby making the U-bit management of the cabinet server more flexible and convenient.

[0067] Optionally, as shown in Figure 3As shown, the first jack 11 is T-shaped. The output bit types corresponding to the T-shaped jack include C13, C15 and C19, so as to allow the insertion of the pins of the C14 plug and the pins of the C20 plug. Accordingly, as shown in Figure 4 , the plug-in gap 6 is also T-shaped, so as to be able to accommodate the pins of the C14 plug and the pins of the C20 plug. In Figure 3 and Figure 4 , the two anti-extraction pieces 5 are in an initial state without being plugged in, Figure 4 , the cross-sectional shapes of the pins of the C14 plug and the pins of the C20 plug are shown in two dashed-line boxes respectively, and the plug-in positions of the two pins in the plug-in gap 6 are shown.

[0068] It should be noted that when the two anti-extraction pieces 5 are in the initial state, the width dimension of the first gap 61 in the first direction should be slightly smaller than the thickness dimension of the pins of the C20 plug, so as to ensure that after the pins enter the plug-in gap 6, the pins can abut against the two anti-extraction pieces 5 and be clamped by the two anti-extraction pieces 5. Similarly, when the anti-extraction piece 5 is in the initial state, the width dimension of the second gap 62 in the first direction should be slightly smaller than the thickness dimension of the pins of the C14 plug, so as to ensure that after the pins enter the plug-in gap 6, the pins can abut against the two anti-extraction pieces 5 and be clamped by the two anti-extraction pieces 5. The first direction is the X direction in Figure 4 , and the initial state refers to a state without external force.

[0069] In some embodiments of the present application, the anti-extraction piece 5 is an anti-extraction plate as shown in Figure 5 , and when assembling the socket module, the first side 51 of the two anti-extraction plates is close to each other, and the second side 52 of the two anti-extraction plates is far away from each other, as shown in Figure 3 and Figure 4 , so as to be arranged in axial symmetry.

[0070] Continuing to refer to Figure 4 and Figure 5 , the first side 51 of each anti-extraction plate is provided with a fourth notch 56, the first gap 61 is formed between the fourth notches 56 of the two anti-extraction plates, and the second gap 62 is formed between the plate walls of the first side 51 of the two anti-extraction plates.

[0071] Optionally, when the plug-in gap 6 is T-shaped, the fourth notch 56 is rectangular or square, and the plate walls of the first side 51 of the two anti-extraction pieces are parallel to each other.

[0072] In the embodiments of the present application, the two anti-dropping pieces 5 can move relative to each other, so that the first sides 51 of the two anti-dropping pieces 5 can be close to or away from each other. When the first sides 51 of the two anti-dropping pieces 5 are close to each other, the width dimension of the insertion gap 6 in the first direction is reduced, the plug inserted into the insertion gap 6 is clamped and difficult to move; when the first sides 51 of the two anti-dropping pieces 5 are away from each other, the width dimension of the insertion gap 6 is increased, the plug inserted into the insertion gap 6 is released and can move.

[0073] In order to realize the relative movement of the two anti-dropping pieces 5, the first side 51 and the second side 52 of each anti-dropping piece 5 are respectively lapped on the movable piece 3 and the fixed piece 4, wherein at least a part of the movable piece 3 is located inside the shell 1 and can reciprocate along the opening direction of the first jack 11 relative to the shell 1; the fixed piece 4 is fixed inside the shell 1 and cannot move relative to the shell 1.

[0074] When the two anti-dropping pieces 5 are assembled, the first side 51 is lapped with the movable piece 3, and the second side 52 is lapped with the fixed piece 4. Therefore, with the movement of the movable piece 3, the first side 51 of the two anti-dropping pieces 5 will be pushed by the movable piece 3 or follow the movement of the movable piece 3 under the action of its own gravity, so as to reduce or increase the width dimension of the insertion gap 6.

[0075] In the embodiments of the present application, in order to meet the requirements of inserting the plug to release the plug and withdrawing the plug to clamp the plug, the relationship between the two anti-dropping pieces 5 and the movable piece 3 is designed as follows: when the movable piece 3 drives the first sides 51 of the two anti-dropping pieces 5 to move towards the direction close to the plug sleeve 2, the distance between the first sides 51 of the two anti-dropping pieces 5 gradually increases, that is, the width dimension of the insertion gap 6 increases; when the movable piece 3 drives the first sides 51 of the two anti-dropping pieces 5 to move away from the plug sleeve 2, the distance between the first sides 51 of the two anti-dropping pieces 5 gradually decreases, that is, the width dimension of the insertion gap 6 decreases.

[0076] As shown in Figure 3 The movable piece 3 includes a bearing portion 31 located between the plug sleeve 2 and the first jack 11, the bearing portion 31 has a second jack 311, and along the insertion direction of the plug, the first jack 11, the second jack 311 and the clamping gap 21 of the plug sleeve 2 are sequentially communicated, and the first sides 51 of the two anti-dropping pieces 5 are lapped on the bearing portion 31. Among them, the orthographic projection of the second jack 311 on the set plane coincides with the orthographic projection of the first jack 11 on the set plane, or is located within the orthographic projection of the first jack 11. And the cross-sectional shape of the second jack 311 can be the same as the cross-sectional shape of the first jack 11, for example, T-shaped. The set plane is perpendicular to the insertion direction of the plug, that is, perpendicular to the axis direction of the first jack 11 and the second jack 311.

[0077] The plug gap 6 can be located on the side of the second insertion hole 311 close to the first insertion hole 11, or on the side of the second insertion hole 311 away from the first insertion hole 11, or, as shown, inside the second insertion hole 311. Figure 2

[0078] It should be noted that the second insertion hole 311 has a certain extension length in the insertion direction of the plug, thereby forming a hole space with a certain volume. The plug gap 6 is located inside the second insertion hole 311, which means that the plug gap 6 overlaps with the hole space of the second insertion hole 311. Among them, when the two anti-dropping pieces 5 are in the initial state, the orthographic projection of the plug gap 6 on the set plane is located within the orthographic projection of the second insertion hole 311 on the set plane, or coincides with the orthographic projection of the second insertion hole 311 on the set plane.

[0079] As shown in Figure 6 and Figure 7 The bearing part 31 is further provided with a first through hole 312 and a second through hole 313 on the two opposite side walls in the first direction, respectively, and the first through hole 312 and the second through hole 313 are distributed on the two sides of the second insertion hole 311 in the radial direction and respectively communicate with the second insertion hole 311; at least a part of the first side 51 of the two anti-dropping pieces 5 respectively extends into the second insertion hole 311 through the first through hole 312 and the second through hole 313. It should be understood that the radial direction of the second insertion hole 311 is perpendicular to the axial direction, and the axis of the first through hole 312 and the axis of the second through hole 313 respectively intersect with the axis of the second insertion hole 311 and do not coincide with the axis of the second insertion hole 311.

[0080] By providing the first through hole 312 and the second through hole 313, at least a part of the two anti-dropping pieces 5 can respectively extend into the second insertion hole 311 from both sides, thereby forming the plug gap 6 inside the second insertion hole 311. Among them, the two anti-dropping pieces 5 can be respectively lapped on the hole wall of the first through hole 312 and the hole wall of the second through hole 313, and / or lapped on the wall surface of the two side walls of the bearing part 31 having the first through hole 312 and the second through hole 313.

[0081] In some embodiments of the present application, as shown in Figure 6 and Figure 7 ​As shown, the side wall of the bearing part 31 is further provided with a first groove 314 and a second groove 315, which are respectively located on two sides of the second insertion hole 311 in the radial direction and open away from the second insertion hole 311. The first groove 314 has a first bottom wall 3141 close to the second insertion hole 311, and the end of the first through hole 312 away from the second insertion hole 311 is located on the first bottom wall 3141, and the first side 51 of one anti-falling piece 5 is movably in contact with the first bottom wall 3141. The second groove 315 has a second bottom wall 3151 close to the second insertion hole 311, and the end of the second through hole 313 away from the second insertion hole 311 is located on the second bottom wall 3151, and the first side 51 of the other anti-falling piece 5 is movably in contact with the second bottom wall 3151. In this way, the first side 51 of the two anti-falling pieces 5 has a part of the plate body extending into the second insertion hole 311, and the remaining part of the plate body is in contact with the first bottom wall 3141 or the second bottom wall 3151, thereby providing structural support for subsequent movement.

[0082] In some embodiments, as shown in Figure 5 and Figure 8 each anti-falling piece 5 is spaced apart from the first side 51 to be provided with a first notch 53 and a second notch 54, which are respectively located on two sides of the fourth notch 56. The first notch 53 and the second notch 54 of one anti-falling piece 5 are movably engaged with the wall surface of the first bottom wall 3141 on both sides of the first through hole 312, and at least part of the plate body structure of the anti-falling piece 5 between the first notch 53 and the second notch 54 extends into the second insertion hole 311 through the first through hole 312. The first notch 53 and the second notch 54 of the other anti-falling piece 5 are movably engaged with the wall surface of the second bottom wall 3151 on both sides of the second through hole 313, and at least part of the plate body structure of the anti-falling piece 5 between the first notch 53 and the second notch 54 extends into the second insertion hole 311 through the second through hole 313.

[0083] In this way, the anti-falling piece 5 is engaged with the wall surface of the first bottom wall 3141 or the second bottom wall 3151 through the first notch 53 and the second notch 54, so that the anti-falling piece 5 and the bearing part 31 have a larger contact area, and the first bottom wall 3141 and the second bottom wall 3151 can reliably support the two anti-falling pieces 5, thereby avoiding the anti-falling piece 5 from falling and tilting due to unstable engagement with the bearing part 31 during movement.

[0084] In addition, the above design can also avoid the anti-falling piece 5 from being designed too long for extending into the second insertion hole 311, that is, the length of the plate body of the anti-falling piece 5 in the first direction is reduced, and the self-weight and material cost of the anti-falling piece 5 are reduced.

[0085] As shown in Figure 6As shown, the two anti-disengagement pieces 5 are arranged in an inclined manner on the bearing portion 31, that is, the farther away from the sleeve 2 along the axis direction of the second insertion hole 311, the farther away from the second insertion hole 311 along the radial direction. Therefore, when the first side 51 of the two anti-disengagement pieces 5 is driven to rotate away from the sleeve 2, the width dimension of the plug-in gap 6 will decrease; when the first side 51 of the two anti-disengagement pieces 5 is driven to rotate close to the sleeve 2, the width dimension of the plug-in gap 6 will increase.

[0086] In some embodiments, as Figure 5 shown, the first notch 53 and the second notch 54 on the anti-disengagement piece 5 are respectively located on the two sides of the fourth notch 56, wherein the first notch 53 and the fourth notch 56 have a spacing, the second notch 54 communicates with the fourth notch 56, and the extension length of the second notch 54 in the first direction is greater than the extension length of the fourth notch 56 in the first direction. Wherein, the first direction is parallel to the arrangement direction of the two anti-disengagement pieces 5, that is, Figure 4 the X direction in the figure.

[0087] Optionally, the side of the first notch 53 away from the second notch 54 extends to the edge of the anti-disengagement piece 5 in a direction away from the second notch 54; and the side of the second notch 54 away from the first notch 53 extends to the edge of the anti-disengagement piece 5 in a direction away from the first notch 53. Therefore, by adopting such a shape of the anti-disengagement piece 5, the identification action during assembly of the anti-disengagement piece 5 and the movable piece 3 can be reduced, the assembly difficulty is further reduced, and the assembly efficiency is improved.

[0088] As Figure 5 and Figure 6 shown, in the embodiments of the present application, the extension length of at least one of the first notch 53 and the second notch 54 in the first direction is greater than the extension length of the fourth notch 56 in the first direction, so that a part of the anti-disengagement piece 5 can extend into the inside of the second insertion hole 311 to abut against the plug-in bolt inserted therein.

[0089] In some embodiments of the present application, as Figure 6 and Figure 7 shown, for the two anti-disengagement pieces 5 arranged in an inclined manner, the groove inner wall of the first recess 314 away from the sleeve 2 has a first inclined surface 3142, and the inclination manner of the first inclined surface 3142 is the same as the inclination manner of the anti-disengagement piece 5 located in the first recess 314; the groove inner wall of the second recess 315 away from the sleeve 2 has a second inclined surface 3152, and the inclination manner of the second inclined surface 3152 is the same as the inclination manner of the anti-disengagement piece 5 located in the second recess 315.

[0090] By setting the first groove 314 and the second groove 315 as inclined surfaces away from the inner wall of the socket 2, the movement of the first side 51 of the anti-disengagement piece 5 can be avoided, thereby avoiding the situation that the bolt cannot enter the insertion gap 6 and the anti-disengagement function of the anti-disengagement piece 6 is invalid due to the inability of the anti-disengagement piece 5 to move.

[0091] It should be noted that in the embodiments of the present application, the first inclined surface 3142 and the second inclined surface 3152 are only the same in the inclined manner, but can have the same or different inclination angles. For example, the inclination angle of the first inclined surface 3142 is equal to the inclination angle of the second inclined surface 3152, and is smaller than the inclination angle of the anti-disengagement piece 5 in the initial state, so as to meet the space requirement of the first side 51 of the anti-disengagement piece 5 during movement. The inclination angle refers to the acute angle between the axial direction of the second jack 311.

[0092] In some embodiments of the present application, continuing to refer to Figure 7 The bearing part 31 is in the shape of a T-shaped and has the same shape as the second jack 311. The bearing part 31 includes a first frame part 316 and a second frame part 317 which are vertically connected in the second direction, wherein the second direction is the Y direction in Figure 4 , the second direction is perpendicular to the first direction and perpendicular to the axial direction of the second jack 311. The length of the first frame part 316 in the first direction is greater than the length of the second frame part 317 in the first direction, the inside of the first frame part 316 is formed with a transversely extending rectangular hole part of the second jack 311, and the inside of the second frame part 317 is formed with a longitudinally extending rectangular hole part of the second jack 311. Correspondingly, the first gap 61 is located in the transversely extending rectangular hole part of the first frame part 316, and the second gap 62 is located in the longitudinally extending rectangular hole part of the second frame part 317. The first inclined surface 3142 and the second inclined surface 3152 are both located on the first frame part 316.

[0093] By designing the shape of the bearing part 31 as a T-shaped, the occupation of the internal space of the socket module housing 1 can be reduced, so as to facilitate the arrangement of other sockets 2, improve the structural compactness of the socket module, and save material cost.

[0094] Optionally, the shape of the bearing part 31 is adapted, as shown in Figure 5 , the extension length of the first notch 53 in the first direction is smaller than the extension length of the second notch 54 in the second direction, so that the first notch 53 can be clamped with the second frame part 317, and the second notch 54 can be clamped with the first frame part 316.

[0095] In some embodiments of the present application, as Figure 9As shown, the movable piece 3 further comprises a limiting part 32 connected with the bearing part 31, and two side walls of the limiting part 32, which are away from each other in the first direction, are respectively provided with a first limiting slot 321 and a second limiting slot 322, and the first limiting slot 321 and the second limiting slot 322 penetrate the limiting part 32 along the axis direction of the first insertion hole 11. Figure 10 As shown, the fixed piece 4 comprises a first extension rod 41 and a second extension rod 42 extending along the axis direction of the first insertion hole 11. Figure 8 The first extension rod 41 and the second extension rod 42 are respectively movably arranged in the first limiting slot 321 and the second limiting slot 322, and are respectively matched with the second side 52 of the two anti-drop pieces 5.

[0096] In the axis direction of the first insertion hole 11, the extension length of the first extension rod 41 and the second extension rod 42 is greater than the length of the first limiting slot 321 and the second limiting slot 322. Therefore, the movable piece 3 can be slidably matched with the first extension rod 41 and the second extension rod 42 based on the limiting part 32, and the first extension rod 41 and the second extension rod 42 can play a guiding role.

[0097] As shown, Figure 9 The normal projection of the limiting part 32 on the setting plane does not overlap with the normal projection of the second insertion hole 311 on the setting plane, so as to prevent the limiting part 32 from hindering the insertion of the plug pin. The sleeve 2 can be located at a position opposite to the second insertion hole 311, so as to facilitate the plug-in matching of the plug pin.

[0098] In some embodiments of the present application, the two anti-drop pieces 5 can be movably clamped with the part of the first extension rod 41 outside the first limiting slot 321 and the part of the second extension rod 42 outside the second limiting slot 322.

[0099] As shown, Figure 5 The second side 52 of the anti-drop piece 5 is provided with a third notch 55. Generally, the third notch 55 is located at the middle position of the second side 52 of the anti-drop piece 5, rather than the edge position, so as to avoid the anti-drop piece 5 from falling off or tilting from the fixed piece 4 during the rotation.

[0100] Continuing to refer to Figures 8 to 10The first extension rod 41 comprises a first rod portion 411 and a first clamping portion 412. The first rod portion 411 is arranged in the first limiting groove 321, and the first rod portion 411 has a first extension end 4111 extending from a side of the first limiting groove 321 close to the anti-disengagement piece 5. The first clamping portion 412 is connected with the first extension end 4111 and clamped with the third notch 55 of one anti-disengagement piece 5. The second extension rod 42 comprises a second rod portion 421 and a second clamping portion 422. The second rod portion 421 is arranged in the second limiting groove 322, and the second rod portion 421 has a second extension end 4211 extending from a side of the limiting portion 32 close to the other anti-disengagement piece 5. The second clamping portion 422 is connected with the second extension end 4211 and clamped with the third notch 55 of the other anti-disengagement piece 5.

[0101] As shown in Figure 3 and Figure 6 , the anti-disengagement plate 43 is movably clamped with the movable piece 3 through the first notch 53 and the second notch 54, and is movably clamped with the fixed piece 4 through the third notch 55. The two sides of the two anti-disengagement pieces 5 are clamped with the movable piece 3 and the fixed piece 4 respectively, which is simple in structure, good in movement effect, and easy to assemble.

[0102] The fixed piece 4 is integrated with the first clamping portion 412 and the second clamping portion 422 for movably clamping with the anti-disengagement piece 5, and is integrated with the first rod portion 411 and the second rod portion 421 for slidingly matching with the limiting portion 32, which is simple in structure, small in space occupation, and easier to assemble.

[0103] In some embodiments of the present application, referring to Figure 10 , at least part of the end faces of the first extension end 4111 and the second extension end 4211 are inclined surfaces. The inclination of the inclined surfaces is that the farther away from the bushing 2 along the axis direction of the second insertion hole 311, the farther away from the second insertion hole 311 along the radial direction of the second insertion hole 311. The inclined surfaces are used to avoid the rotation of the anti-disengagement piece 5, which avoids the situation that the bolt cannot enter the insertion gap 6 and the anti-disengagement function of the anti-disengagement piece 5 is invalid due to the inability of the anti-disengagement piece 5 to rotate.

[0104] It should be noted that, since the width size of the insertion gap 6 is smaller than the size of the bolt to be inserted when the two anti-disengagement pieces 5 are in the initial state, the two anti-disengagement pieces 5 will be pressed during the insertion of the bolt, and the pressure will be transmitted to the bearing portion 31 of the movable piece 3, causing the movable piece 3 to move towards the bolt to increase the width size of the insertion gap 6. However, such design also causes the movable piece 3 to need to move a large distance to increase the insertion gap 6 to a size sufficient to allow the bolt to be inserted, thereby causing the movable piece 3 to require a large movement space, which is not conducive to the miniaturization design of the socket module.

[0105] To solve the above problems, in some embodiments of the present application, the minimum distance between the first engaging portion 412 and the first bottom wall 3141 of the first recess 314 in the first direction is greater than the minimum distance between the third gap 55 and the second gap 54 of one anti-disengagement piece 5 installed in the first recess 314 and in the initial state, and is less than the thickness dimension of the plug; the minimum distance between the second engaging portion 422 and the second bottom wall 3151 of the second recess 315 is greater than the minimum distance between the third gap 55 and the second gap 54 of the other anti-disengagement piece 5 installed in the second recess 315 and in the initial state, and is less than the thickness dimension of the plug.

[0106] In this way, when in the initial state, the two anti-disengagement pieces 5 are in contact with the first bottom wall 3141 of the first recess 314 and the second bottom wall 3151 of the second recess 315 under the action of their own gravity, but have a small gap between the first engaging portion 412 and the second engaging portion 422, respectively. When the plug is inserted, the two anti-disengagement pieces 5 rotate the first side 51 in the direction close to the plug sleeve 2 under the insertion pressure of the plug, and at the same time, the two anti-disengagement pieces 5 also move away from each other in the first direction, thereby shortening the insertion gap 6 to the size that allows the plug to be inserted, and the distance required for the movement of the movable piece 3. Therefore, the requirement for the movement space of the movable piece 3 is reduced, and the internal space utilization of the socket module is more reasonable.

[0107] In some embodiments of the present application, as shown in Figure 1 and Figure 7 The movable piece 3 further comprises an elastic pressing portion 33 connected to the bearing portion 31 or the limiting portion 32, and the elastic pressing portion 33 is always in an elastic compression state and provides an elastic force parallel to the axis direction of the first insertion hole 11.

[0108] When there is no plug inserted in the socket module, the bearing portion 31 elastically abuts against the shell wall where the first insertion hole 11 of the shell 1 is located under the action of the elastic force of the elastic pressing portion 33. During the process of inserting the plug into the plug sleeve 2, the elastic pressing portion 33 always applies a force to the first side 51 of the two anti-disengagement pieces 5 through the bearing portion 31, which is in the direction of the first insertion hole 11 and away from the plug sleeve 2, so that the two anti-disengagement pieces 5 always abut against the plug during the insertion process of the plug, thereby improving the hand feeling of inserting the plug and ensuring effective and reliable anti-disengagement effect.

[0109] However, such a design will cause the plug to always be clamped by the two anti-disengagement pieces 5, which will hinder the withdrawal of the plug from the insertion hole. Therefore, referring to Figure 1An operation hole 12 can be arranged on the shell 1, at least a part of the elastic pressing part 33 can be exposed from the operation hole 12 and can move along the axial direction of the operation hole 12. In this way, when the plug pin needs to be withdrawn, the part of the elastic pressing part 33 exposed from the operation hole 12 can be pressed to move towards the plug sleeve 2, and the bearing part 31 and the first side 51 of the two anti-disengagement pieces 5 are driven to move towards the plug sleeve 2, so as to release the plug pin, and then the plug pin can be smoothly withdrawn from the first insertion hole 11.

[0110] Optionally, as shown in the figure, the elastic pressing part 33 comprises a pressing column 331 and an elastic body 332, the pressing column 331 is connected with the limiting part 32, and the two ends of the elastic body 332 are respectively elastically abutted or elastically connected with the pressing column 331 and the bottom plate 13 of the shell 1. Exemplarily, the elastic body 332 can be a compression spring. Figure 11

[0111] In some embodiments of the present application, the socket module is an axisymmetric structure. In this way, the molding of the shell 1, the movable piece 3, the fixed piece 4 and the anti-disengagement piece 5 is facilitated, and the assembly and arrangement of each component are also facilitated, which is beneficial to realize automatic assembly.

[0112] The cooperation process between the socket module and the plug pin provided by the embodiments of the present application is as follows:

[0113] In the initial state, the plug pin enters the second insertion hole 311 through the first insertion hole 11 under the action of external force, and since the width dimension of the insertion gap 6 in the first direction is smaller than the thickness dimension of the plug pin, the plug pin will first contact the first side 51 of the two anti-disengagement pieces 5; as the plug pin continues to be inserted, the first side 51 of the two anti-disengagement pieces 5 is pressed and rotates towards the plug sleeve 2, and at the same time, the two anti-disengagement pieces 5 move away from each other in the first direction, so that the width dimension of the insertion gap 6 in the first direction rapidly increases, and the plug pin can quickly enter the insertion gap 6; moreover, in the process of rotation of the two anti-disengagement pieces 5, the bearing part 31 is also subjected to the pressure from the two anti-disengagement pieces 5 and moves towards the plug sleeve 2, so as to further compress the elastic body 332; subsequently, the plug pin entering the insertion gap 6 continues to move towards the plug sleeve 2, and finally enters the clamping gap 21 of the plug sleeve 2. After the external force on the plug pin is removed, the elastic body 332 exerts an elastic force on the pressing column 331, and the elastic force is transmitted to the first side 51 of the two anti-disengagement pieces 5 through the limiting part 32 and the bearing part 31, so that the first side 51 tightly abuts against the plug pin, and thus the plug pin is difficult to be pulled out from the first insertion hole 11 and the clamping gap 21 of the plug sleeve 2.

[0114] ​When it is needed to pull out the plug, a pressing force is applied to the pressing column 331, so that the elastic body 332 is compressed and deformed, and the bearing part 31 also continues to move towards the direction close to the socket 2, so that the first side 51 of the two anti-dropping pieces 5 is no longer forced, but continues to rotate towards the direction close to the socket 2, so that the width size of the plug insertion gap 6 in the first direction is further increased to be greater than the thickness size of the plug, at this time, the plug can be easily pulled out from the clamping gap 21 and the first plug hole 11 in turn, and finally the pressing force applied to the pressing column 331 is removed.

[0115] The power distribution unit provided by the embodiment of the present application comprises the socket module provided by the above embodiment.
