Description

Technical Field

[0001] This application relates to the field of electrical equipment technology, specifically to an anti-disconnect socket. Background Technology

[0002] A power outlet is a very common electrical device, widely used in people's daily lives. People draw power from electrical appliances by connecting the power cord plug to the socket on the outlet.

[0003] In related technologies, when a plug to be powered is inserted into a socket, the plug's pins are usually clamped by the socket's sleeve, thus securing the plug to the socket.

[0004] However, the application scenarios of sockets are usually quite diverse and complex. For example, when using a socket to draw power, it is often necessary to drag the appliance or the socket, which can cause the plug that is drawing power from the socket to become loose under the pull, resulting in economic losses. Summary of the Invention

[0005] In view of this, this application provides an anti-detachment socket that can lock the plug in place, thereby reducing the risk of the plug accidentally falling out of the socket.

[0006] The specific technical solution adopted in this application is as follows:

[0007] This application provides an anti-disengagement socket, which includes a housing, and a socket assembly, an anti-disengagement component, and an adjustment assembly mounted on the housing;

[0008] The socket assembly is located inside the housing and corresponds to the socket on the housing;

[0009] The anti-disengagement component is located between the socket and the sleeve assembly, and the anti-disengagement component has an opening located in the insertion direction of the socket;

[0010] The anti-detachment component is connected to the adjustment component, which can drive the anti-detachment component to rotate and control the rotation angle of the anti-detachment component. When the adjustment component moves from the unlocked position to the locking direction, the projected area of ​​the opening in the insertion direction becomes smaller.

[0011] Optionally, when the plug pin is inserted into the socket and the adjusting component is moved to the locked position, the corresponding inner wall of the opening abuts against the pin.

[0012] Optionally, the anti-detachment socket further includes a limiting member, which is connected to the adjusting assembly. The adjusting assembly can drive the limiting member to rotate and can control the rotation angle of the limiting member.

[0013] When the adjustment component moves from the unlocked position to the locking direction, the limiting member gets closer to the projection of the jack in the insertion direction.

[0014] Optionally, the first end of the limiting member is connected to the anti-detachment member, the second end of the limiting member is a free end, and relative to the first end, the second end of the limiting member is away from the anti-detachment member in the insertion direction and approaches the opening in a direction perpendicular to the insertion direction;

[0015] When the adjustment component is in the unlocked position, there is a gap between the limiting member and the jack in the projection of the jack in the insertion direction;

[0016] When the plug pin is inserted into the socket and the adjusting component is moved to the locked position, the second end of the limiting member abuts against the plug pin.

[0017] Optionally, the adjustment assembly includes a holding part, a supporting part, and an operating part;

[0018] Both the retaining part and the supporting part are located inside the housing, wherein the supporting part is connected to the operating part through the retaining part, and the portion of the supporting part away from the retaining part is connected to the anti-detachment component;

[0019] At least a portion of the operating part extends outside the housing and is adapted to be actuated.

[0020] Optionally, the housing is provided with a mounting hole, the operating part extends out of the mounting hole and can rotate relative to the mounting hole;

[0021] The retaining part has a first external thread, the supporting part has a first threaded hole, the retaining part passes through the first threaded hole and is threadedly connected to the supporting part through the first external thread.

[0022] Optionally, the operating part has a second external thread;

[0023] The housing has a second threaded hole, the operating part passes through the second threaded hole, and is threadedly connected to the housing through the second external thread.

[0024] Optionally, the retaining part, the supporting part, and the operating part are integrally formed.

[0025] Optionally, a groove is provided on the side of the support near the anti-detachment member, and a portion of the anti-detachment member is located in the groove and connected to the support;

[0026] The opening of the groove has a chamfer or bevel. When the adjustment component is in the locked position, the surface of the anti-disengagement component facing away from the rotation direction abuts against the chamfer or bevel.

[0027] Optionally, the housing may further include a blocking element;

[0028] The blocking member abuts against the end of the anti-disengagement member away from the groove, thereby preventing the end of the anti-disengagement member away from the groove from moving toward the insertion hole.

[0029] Optionally, an indicator structure is provided on the operating part or on the housing near the operating part, the indicator structure being used to indicate at least one of the action and direction of switching the adjustment component between the unlocked position and the locked position.

[0030] The anti-dislodge socket provided in this application embodiment has an anti-dislodge component, a limiting component, and an adjusting component installed on its housing. When no plug is inserted into the anti-dislodge socket and the adjusting component is in the unlocked position, the opening of the anti-dislodge component corresponds to the socket hole, so the plug pin can be inserted into the socket assembly by passing through the socket hole and the opening in sequence. After the plug is inserted into the anti-dislodge socket, the adjusting component can be operated to move from the current unlocked position to the locked position, causing the anti-dislodge component and the limiting component to rotate until the inner wall of the opening of the anti-dislodge component jams the plug pin, and the limiting component also abuts against the plug pin. Due to the large friction between the plug pin, the opening, and the limiting component, it is difficult to pull out the plug directly, thus reducing the risk of the plug inserted into the anti-dislodge socket accidentally falling out, and realizing the anti-dislodge function.

[0051] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0052] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0053] The directional terms used in the embodiments of this invention, such as "up," "down," "left," "right," "top," "bottom," and "side," are all designated as follows: Figure 1 and Figure 2 The orientation of the anti-disconnect socket shown is a reference. The orientation of the socket on the housing is defined as "up" or "top," the orientation opposite the socket on the housing is defined as "down" or "bottom," the orientation of the socket corresponding to the ground wire in the three-hole socket on the housing relative to the other two sockets is defined as "left," and the orientation of the two sockets corresponding to the live wire and neutral wire in the three-hole socket on the housing relative to the socket corresponding to the ground wire is defined as "right." Furthermore, the direction of the plug's insertion into the socket is defined as downward, and the direction of the plug's removal from the socket is defined as upward. The insertion and removal direction of the plug is defined as the vertical direction, and correspondingly, the direction perpendicular to the vertical is defined as the horizontal direction. These directional terms are used in this embodiment of the invention merely to more clearly describe the structures and their relationships, and are not intended to describe absolute orientations.

[0054] See Figure 1 and Figure 2 This application provides an anti-disengagement socket, which includes a housing 10, and a socket assembly 20, an anti-disengagement member 30, and an adjustment assembly 50 mounted on the housing 10. The socket assembly 20 is located inside the housing 10 and corresponds to the socket 11 on the housing 10; the anti-disengagement member 30 is located between the socket 11 and the socket assembly 20, and the anti-disengagement member 30 has an opening 31 located in the insertion direction of the socket 11; the anti-disengagement member 30 is connected to the adjustment assembly 50, which can drive the anti-disengagement member 30 to rotate and control the rotation angle of the anti-disengagement member 30, wherein when the adjustment assembly 50 moves from the unlocked position to the locked position, the projected area of ​​the opening 31 in the insertion direction becomes smaller.

[0055] Understandably, in the unlocked position, the adjusting component 50 does not rotate the anti-disengagement component 30, or can only rotate the anti-disengagement component 30 by a small angle. At this time, the pin 61 of the plug 60 can be freely inserted into or pulled out of the socket assembly 20. When the adjusting component 50 moves from the unlocked position to the locking position, it will pass through at least one of the locked position and the locked position.

[0056] The locking position generally refers to the position of the adjusting component 50 when it can just lock the plug 60 inserted into the anti-dislodgement socket, making it difficult for it to fall out of the socket. The locking position is not fixed; it is usually determined by the size of the pin 61 of the plug 60 inserted into the anti-dislodgement socket, and varies due to differences in the size of the pin 61 of different plugs 60. For example... Figure 4 As shown, when the pin 61 of the plug 60 is inserted into the socket 11 and the adjusting component 50 is moved to the locking position, the corresponding inner wall of the opening 31 abuts against the pin 61.

[0057] The locked position generally refers to the position of the adjusting component 50 when it at least just prevents the plug 60 from being inserted into the anti-disengagement socket. For the same adjusting component 50, the locked position is usually a fixed position, and the distance between the locked position and the unlocked position corresponds to the maximum operable distance of the adjusting component 50 and the maximum rotation range of the anti-disengagement component 30. Generally, when the adjusting component 50 moves from the unlocked position to the locked position, it usually passes through the locked position first and then the locked position. When the pin 61 of the plug 60 is not inserted into the socket 11 and the adjusting component 50 moves to the locked position, the projected area of ​​the opening 31 in the insertion direction is less than or equal to the projected area of ​​the opening 31 in the insertion direction in the locked position, and the overlap of the projection of the limiting member 40 and the socket 11 in the insertion direction is greater than or equal to the overlap of the projection of the limiting member 40 and the socket 11 in the insertion direction in the locked position.

[0058] It should be noted that in some embodiments of this application, the locking position and the locking position may be the same position. In this case, although the area of ​​the projection of the opening 31 in the insertion direction is equal to or approximately equal to the cross-sectional area of ​​the pin 61, it is still difficult to insert the plug 60 into the socket.

[0059] However, in some other embodiments of this application, the locking position and the locking position can also be different positions. The locking position is located between the locking position and the unlocking position. This locking position can accommodate plugs 60 of different sizes and tolerances to avoid failure to lock the effective pin 61. On the other hand, it can also effectively prevent the plug 60 and other objects from being inserted, thus playing a protective and anti-electric shock role.

[0060] The socket includes a functional module, which is typically electrically connected to the power supply line. By connecting and disconnecting the appliance's plug 60 from the socket's functional module, the appliance can draw power from and disconnect from the socket. The functional module includes a socket assembly 20, which comprises a socket. In some embodiments, the socket assembly 20 may also include a protective door on top of the socket, or a wiring terminal connected to the socket. The number of sockets is typically equal to the number of socket holes 11, and each socket corresponds to one socket hole 11. For example, for a three-hole socket, there are generally three sockets, each located in the insertion direction of one of the three socket holes 11, such as directly below each socket hole 11.

[0061] The anti-dislodgement component 30 is used to prevent the plug 60 inserted into the anti-dislodgement socket from falling out. The anti-dislodgement component 30 is typically made of a material with high hardness and strength, such as steel, so that it can securely hold the pin without being damaged. Normally, after the anti-dislodgement component 30 has engaged the pin 61, the plug 60 is difficult to pull out.

[0062] In this embodiment, the anti-detachment component 30 is connected to the adjusting component 50 and can rotate under the actuation of the adjusting component 50. Here, "rotation" refers to a change in the tilt angle of the anti-detachment component 30 before and after actuation. For example, before actuation, the anti-detachment component 30 is horizontally placed; after rotation at a certain angle, it is tilted on a non-horizontal surface. Of course, the "rotation" of the anti-detachment component 30 can include not only a change in its tilt angle but also a change in its position, such as moving upwards or to the left after rotation. In other words, the rotation method of the anti-detachment component 30 can be set according to requirements, as long as it does not obstruct the insertion or removal of the pin 61 from the sleeve assembly 20 before rotation, and after rotation, prevents the pin 61 from being inserted or locks it in place, making it difficult to remove.

[0063] Adjustment component 50 is a component used to adjust the position of anti-detachment part 30. When the adjusting component 50 is in the unlocked position, due to the opening 31, the anti-disengagement component 30 will not block the insertion direction of the socket 11. Therefore, the plug 60 can pass smoothly through the socket 11 and be inserted into or pulled out of the socket assembly 20. When the adjusting component 50 moves from the unlocked position to the locked position, the anti-disengagement component 30 rotates under the action of the adjusting component 50, resulting in changes in position and tilt angle. The projected area of ​​the opening 31 in the insertion direction gradually decreases. Until the adjusting component 50 moves from the unlocked position to the locked position, if the pin 61 is not inserted into the socket assembly 20 at this time, the projected area of ​​the opening 31 on the anti-disengagement component 30 in the insertion direction will decrease to a degree sufficient to block the insertion of the plug 60, for example, to a degree smaller than the cross-sectional area of ​​the pin 61. If the pin 61 is not inserted into the socket assembly 20 at this time, the corresponding inner wall of the opening 31 on the anti-disengagement component 30 will abut against the pin 61.

[0064] In some embodiments of this application, the anti-disengagement socket may further include a limiting member 40, which is connected to the adjusting assembly 50 and can rotate under the action of the adjusting assembly 50. The adjusting assembly 50 can control the rotation angle of the limiting member 40 and keep the limiting member 40 unchanged at that rotation angle. When the adjusting assembly 50 moves from the unlocked position to the locking direction, the limiting member 40 is closer to the projection of the socket 11 in the insertion direction.

[0065] The limiting member 40 is the main functional component that prevents the plug 60 from being inserted in the locked position, and it also locks the pin 61 together with the anti-disengagement member 30 when the adjusting component 50 is in the locked position. The limiting member 40 is usually quite hard and strong, thus ensuring that it effectively prevents the pin 61 from being damaged by impact.

[0066] Understandably, in the unlocked position, the adjusting component 50 does not rotate the limiting member 40, or can only rotate the limiting member 40 by a small angle. At this time, the limiting member 40 does not obstruct the insertion direction of the socket 11, nor does it contact the pin 61. Therefore, the pin 61 of the plug 60 can be freely inserted into or removed from the socket assembly 20. In the locked position, the pin 61 is locked by the anti-disengagement component 30 and the limiting member 40 together. At this time, unless the adjusting component 50 is switched to the unlocked position, it is difficult to remove the plug 60. In the locked position, the limiting member 40 obstructs the insertion direction of the socket 11, preventing the plug 60 from being inserted into the socket assembly 20.

[0067] For example, Figure 1 This is a schematic diagram of an anti-dislodgement socket with an adjustment component 50 in the unlocked position, provided as an embodiment of this application. Figure 1In the middle, the opening 31 on the anti-dislodgement component 30 is directly opposite the socket 11 and the socket assembly 20, and the plane where the opening 31 is located is parallel to the plane where the socket 11 is located. The limiting component 40 is located on one side of the socket, so it will not block the insertion direction of the socket 11. At this time, the pin 61 of the plug 60 can easily pass through the socket 11 and the opening 31 and be inserted into or pulled out of the socket assembly 20.

[0068] For example, Figure 2 This is a schematic diagram of an anti-disengagement socket when the adjustment component 50 is in the locked position, as provided in an embodiment of this application. Figure 2 In the process, the anti-disengagement component 30 and the limiting component 40 rotate under the action of the adjusting component 50, thereby reducing the projected area of ​​the opening 31 in the insertion direction, and the limiting component 40 also forms a blockage in the insertion direction of the socket 11. If the plug 60 is not yet inserted into the anti-disengagement socket at this time, such as Figure 2 As shown, in this state, plug 60 cannot be inserted into the anti-disconnect socket. The limiting member 40 acts like a safety door, preventing plug 60 from being inserted and also preventing other objects (such as a child's finger) from being inserted into the socket 11 and causing electric shock. If plug 60 is already inserted into the anti-disconnect socket at this time, such as... Figure 4 As shown, due to the obstruction of the pin 61, the adjusting component 50 will only reach the locked position and not the closed position (unless the locked and closed positions are the same). At this time, the corresponding inner wall of the opening 31 of the anti-disengagement component 30 will abut against the inserted pin 61, and the limiting component 40 will also abut against the pin 61. The corresponding inner wall generally refers to the inner wall of the opening 31 on the opposite sides of the pin 61 that can abut against it as the anti-disengagement component 30 rotates. It is usually also the inner wall on the opposite sides of the opening 31. Therefore, due to the large friction at the contact point between the pin 61, the opening 31, and the limiting component 40, it is difficult to pull out the plug 60 directly, thus achieving the anti-disengagement function. Furthermore, compared to an anti-disengagement socket that only has an anti-disengagement component 30, in this embodiment, the inner walls on both sides of the opening 31 and the limiting component 40 abut against the pin 61, thereby forming a cooperation of at least three locking points, making the anti-disengagement effect more stable. At the same time, under the adjustment of the adjusting component 50, the tilt range of the anti-disengagement component 30 and the rotation range of the limiting component 40 are relatively large, so it can be used for sockets of different sizes and specifications, solving the problem of easy loosening of plugs 60 of various sizes and shapes during use.

[0069] In some embodiments of this application, the first end of the limiting member 40 is connected to the anti-disengagement member 30, and the second end of the limiting member 40 is a free end; relative to the first end of the limiting member 40, the second end of the limiting member 40 is away from the anti-disengagement member 30 in the insertion direction and approaches the opening 31 in a direction perpendicular to the insertion direction; when the adjusting component 50 is in the unlocked position, there is a gap between the projection of the limiting member 40 and the socket 11 in the insertion direction; when the pin 61 of the plug 60 is inserted into the socket 11 and the adjusting component 50 is moved to the locked position, the second end of the limiting member 40 abuts against the pin 61.

[0070] In this context, a free end generally refers to an end that is not connected to other structures. In this embodiment, the second end of the limiting member 40 is a free end, adapted to abut against the pin 61 of the plug 60 after rotation. Although the second end of the limiting member 40 is closer to the projection of the socket 11 in the insertion direction than the first end in the direction perpendicular to the insertion direction, there is a gap between the limiting member 40 and the projection of the socket 11 in the insertion direction in the unlocked position, thus not obstructing the insertion of the plug 60. Exemplarily, the limiting member 40 may include, but is not limited to, structures such as an arc-shaped plate, an L-shaped plate, or a T-shaped plate, and the limiting member 40 may also be a semi-enclosed structure, capable of abutting against more than one side of the pin 61 when abutting against it.

[0071] In some embodiments of this application, the anti-detachment member 30 can be a flat plate structure, and the limiting member 40 can be formed by bending a plate cut out from one side of the anti-detachment member 30. For example... Figure 3 As shown, the plate body in the middle part of the anti-slip member 30 can be cut and bent at one end of the anti-slip member 30, so that there are remaining parts 32 on both sides of the cut plate body, and the remaining parts 32 can be used for connection with the adjustment component 50.

[0072] It should be noted that, in this embodiment, the first end of the limiting member 40 can be connected to any position on the anti-detachment member 30, as long as it can avoid the insertion direction of the socket 11 before rotation and block the insertion direction of the socket 11 after rotation. For example, in Figure 1In one embodiment, the first end of the limiting member 40 is connected to the upper surface of the anti-detachment member 30 and located on the right side of the opening 31. The connection point between the adjusting component 50 and the anti-detachment member 30 and the limiting member 40 is located on the same side of the opening 31, also on the right side. When the adjusting component 50 moves upward, the unlocking position is switched to the locking position. However, in other embodiments, the first end of the limiting member 40 can also be connected to the lower surface of the anti-detachment member 30 and can also be located on the left side of the opening 31. The connection point between the adjusting component 50 and the anti-detachment member 30 and the limiting member 40 can also be located on opposite sides of the opening 31. For example, when the first end of the limiting member 40 is connected to the lower surface of the anti-detachment member 30 and located on the right side of the opening 31, and the connection point between the adjusting component 50 and the anti-detachment member 30 and the limiting member 40 is located on the same side of the opening 31, also on the right side, when the adjusting component 50 moves downward, the unlocking position is switched to the locking position. For example, the first end of the limiting member 40 is connected to the upper surface of the anti-detachment member 30 and is located on the left side of the opening 31. The connection between the adjusting component 50 and the anti-detachment member 30 and the limiting member 40 is located on the opposite side of the opening 31, that is, on the right side. At this time, when the adjusting component 50 moves downward, the unlocking position is switched to the locking position.

[0073] like Figure 3 As shown in the embodiment of this application, the second end of the limiting member 40 may include a first surface 41, which abuts against the pin 61 when the adjusting component 50 is in the locked position.

[0074] The first surface 41 can be a plane, and when the adjusting component 50 is in the locked position, the plane containing the first surface 41 may not be parallel to the insertion direction, so that only a portion of the first surface 41 abuts against the pin 61 when it abuts against the pin 61; or, as Figure 4 As shown, when the adjusting component 50 is in the locked position, the plane where the first surface 41 is located can be parallel to the insertion direction, so that the first surface 41 has a larger contact area when it abuts against the pin 61, or even the first surface 41 is completely abutting against the pin 61, thus there is greater friction between the limiting member 40 and the pin 61.

[0075] Normally, when the limiting member 40 and the anti-detachment member 30 have abutted against the pin 61 or have reached the locked position, the limiting member 40 and the anti-detachment member 30 need to be limited to prevent the adjustment component 50 from being operated under misoperation, causing it to drive the limiting member 40 and the anti-detachment member 30 to continue to rotate, thereby causing damage and misalignment to the limiting member 40 and the anti-detachment member 30.

[0076] Considering the above factors, in some embodiments of this application, when the adjusting component 50 is in the locked position, the limiting member 40 may abut against the housing 10; and / or, when the adjusting component 50 is in the locked position, the adjusting component 50 abuts against the housing 10.

[0077] The second end of the limiting member 40 includes a second surface 42, which can abut against the housing 10 when the adjusting component 50 is in the locked position.

[0078] like Figure 4 As shown, it illustrates a cross-sectional schematic diagram of an anti-dislodgement socket with a plug 60 inserted. Figure 4 In the middle, the adjusting component 50 is currently in the locked position (the locked position is the same as the locked position). At this time, the second surface 42 of the limiting member 40 abuts against the housing 10, and the adjusting component 50 also abuts against the housing 10. Therefore, even if the adjusting component 50 is misoperated, it cannot be moved upward, so it will not cause damage to the anti-detachment member 30 and the limiting member 40.

[0079] In the embodiments of this application, such as Figure 5 and Figure 6 As shown, the adjustment assembly 50 may include a holding portion 51, a support portion 52, and an operating portion 53; both the holding portion 51 and the support portion 52 are located inside the housing 10, wherein the support portion 52 is connected to the operating portion 53 through the holding portion 51, and the portion of the support portion 52 away from the holding portion 51 is connected to the anti-detachment member 30; at least a portion of the operating portion 53 extends outside the housing 10 and is adapted to be actuated.

[0080] The operating unit 53 is the part on the adjustment component 50 that receives actuation. For example, when a user wants to adjust the adjustment component 50 from the unlocked position to the locked position or the closed position, they only need to perform the corresponding operation on the operating unit 53.

[0081] In some embodiments, an indicator structure 54 is provided on the operating part 53 or on the housing 10 near the operating part 53. The indicator structure 54 is used to indicate at least one of the action and direction for switching the adjusting component 50 between the unlocked position and the locked position, or it can also be used to indicate at least one of the action and direction for switching the adjusting component 50 between the unlocked position and the locked position. See, for example, [link to relevant documentation]. Figure 12 An indicator arrow is provided on the housing 10 near the operating part 53. This arrow can indicate the direction from the unlocked position to the locked position, or the direction from the locked position to the unlocked position. Of course, in other examples, the arrow can also be bidirectional, with the text "locked" or "unlocked" corresponding to the position at the arrow; or, the text "rotate" or similar indicating the action can also be provided at the arrow. The pattern and style of the indicator structure 54 are not limited in this embodiment, as long as they can indicate the action and / or direction of switching the adjustment component 50 between the unlocked and locked positions.

[0082] The support part 52 is a component used to support and actuate the anti-detachment member 30. The support part 52 and the anti-detachment member 30 can be movably connected, for example, by means of a pin or hinge, or by a snap-fit ​​with a large fitting clearance, so that the anti-detachment member 30 has a high degree of freedom when the support part 52 moves the anti-detachment member 30.

[0083] In some embodiments of this application, such as Figure 9 As shown, a groove 522 is provided on the side of the support 52 near the anti-detachment member 30. A portion of the anti-detachment member 30 is located in the groove 522 and connected to the support 52. The opening 31 of the groove 522 has a chamfer or bevel 523. When the adjusting assembly 50 is in the locked or closed position, the surface of the anti-detachment member 30 opposite to the rotation direction abuts against the chamfer or bevel 523. The surface opposite to the rotation direction refers to the surface of the anti-detachment member 30 that is oriented opposite to the rotation direction. For example, for a horizontally anti-detachment member 30, when rotated clockwise, the anti-detachment member 30 momentarily rotates approximately downwards; therefore, the surface opposite to the rotation direction refers to the upper surface of the anti-detachment member 30. When rotated counterclockwise, the anti-detachment member 30 momentarily rotates approximately upwards; therefore, the surface opposite to the rotation direction refers to the lower surface of the anti-detachment member 30.

[0084] by Figure 8 Taking the structure and orientation shown as an example, since the support 52 and the anti-detachment member 30 are not rigidly connected, when the support 52 drives a part of the anti-detachment member 30 to rotate upward, due to its own weight and other reasons, the part of the anti-detachment member 30 located outside the groove 522 will not rotate upward, resulting in the anti-detachment member 30 being tilted. The tilted anti-detachment member 30 can just abut against the chamfer or inclined surface 523 of the groove 522. Since the contact area between the chamfer or inclined surface 523 and the anti-detachment member 30 is large, the position of the anti-detachment member 30 is more stable.

[0085] The retaining part 51 is a component used to connect the operating part 53 and the support part 52. Under normal circumstances, the connection between the retaining part 51 and the operating part 53 and the support part 52 is rigid, so that the retaining part 51 can keep the support part 52 in the current position regardless of whether the adjusting component 50 is in the unlocked position, the locked position or the closed position, and can even keep the support part 52 in any position during the entire adjustment process.

[0086] This application provides two possible structures for the adjustment component 50, both of which can meet the adjustment requirement of switching between any position between the locked and unlocked positions. The following describes... Figure 7 and Figure 8 The two possible regulatory structures will be described in detail.

[0087] like Figure 7As shown, in some embodiments of this application, the housing 10 is provided with a mounting hole 12, the operating part 53 extends out from the mounting hole 12 and can rotate relative to the mounting hole 12; the retaining part 51 has a first external thread, the supporting part 52 has a first threaded hole 521, the retaining part 51 passes through the first threaded hole 521 and is threadedly connected to the supporting part 52 through the first external thread.

[0088] exist Figure 7 Currently, the adjusting component 50 is in the locked position. To switch the adjusting component 50 to the unlocked position, the operating part 53 can be rotated, causing the retaining part 51 to rotate along with the operating part 53. Due to the threaded engagement between the retaining part 51 and the support part 52, when the retaining part 51 rotates, the first threaded hole 521 of the support part 52 and other parts will move downward along the axis of the retaining part 51, and drive the part of the anti-disengagement member 30 located in the groove 522 to move downward together until the adjusting component 50 moves to the locked position. Figure 10 The unlock position is shown. Conversely, when it is necessary to adjust component 50 from... Figure 10 The unlock position shown has been switched to Figure 7 When the locking position is shown, simply rotate the operating part 53 in the opposite direction to move the first threaded hole 521 of the support part 52 and other parts upward along the axis of the holding part 51, and move the part of the anti-disengagement member 30 located in the groove 522 upward together. This will not be described in detail here.

[0089] like Figure 8 As shown, in some other embodiments of this application, the operating part 53 has a second external thread; the housing 10 has a second threaded hole 13, the operating part 53 passes through the second threaded hole 13, and is threadedly connected to the housing 10 through the second external thread.

[0090] exist Figure 8 Currently, the adjustment component 50 is in the locked position. To switch the adjustment component 50 to the unlocked position, the operating part 53 can be rotated, causing the operating part 53 to rotate. Due to the threaded fit between the operating part 53 and the housing 10, while rotating, the operating part 53 will also move downward relative to the housing 10 along the axis of the operating part 53. At the same time, it will drive the holding part 51 and the support part 52 to move downward together, and the part of the anti-detachment member 30 located in the groove 522 of the support part will also move downward until the adjustment component 50 moves to the unlocked position. Conversely, when it is necessary to switch the adjustment component 50 from the unlocked position to the locked position, simply rotate the operating part 53 in the opposite direction, causing the operating part 53, the holding part 51, and the support part 52 to move upward together along the axis of the operating part 53, and driving the part of the anti-detachment member 30 located in the groove 522 to move upward together. This will not be described in detail here.

[0091] In some embodiments, the retaining part 51, the supporting part 52, and the operating part 53 can be integrally formed, which simplifies the assembly process and reduces assembly costs. However, in other embodiments, the retaining part 51, the supporting part 52, and the operating part 53 can also be separately formed to reduce the difficulty and cost of processing and manufacturing.

[0092] It should be noted that, as mentioned earlier, the adjusting component 50 can be limited by abutting against the housing 10 in the locked position. In fact, this limitation is achieved by the support member abutting against the housing 10 to prevent damage to the anti-detachment component 30 and the limiting component 40. However, for Figure 8 The structure of the adjustment component 50 shown can be limited not only by abutting against the housing 10 based on the second surface 42 of the limiting member 40, as mentioned above, and / or by abutting against the housing 10 based on the support member, but also by abutting against the housing 10 based on the operating part 53 of the adjustment component 50.

[0093] See also Figure 8 The adjustment assembly 50 may also include a limiting part located inside the housing 10 and on the side of the second external thread near the retaining part 51. When the adjustment assembly 50 is in the locked position, the limiting part abuts against the housing 10, so that even if the adjustment assembly 50 is accidentally operated, it cannot be moved upward, thus preventing damage to the anti-disengagement member 30 and the limiting member 40.

[0094] In some embodiments of this application, such as Figure 10 As shown, the housing also includes a blocking member 14, which abuts against the end of the anti-detachment member 30 away from the groove 522, thereby preventing the end of the anti-detachment member 30 away from the groove 522 from moving toward the socket 11.

[0095] If the blocking member 14 is not provided, while the support member moves the part of the anti-detachment member 30 located in the groove 522, the other part of the anti-detachment member 30 may also be moved in the same direction. As a result, the rotation angle that the anti-detachment member 30 can form is small, and the tilt angle is also small. Consequently, the corresponding inner wall of the opening 31 cannot hold the pin 61, that is, the anti-detachment member 30 cannot rotate effectively.

[0096] After the blocking member 14 is set, the end of the anti-detachment member 30 away from the groove 522 cannot move together with the support member. At this time, the anti-detachment member 30 rotates approximately around the end away from the groove 522 as the rotation center. Therefore, the anti-detachment member 30 can rotate a large range and tilt a large angle. The corresponding inner wall of the opening 31 can effectively lock the pin 61 to prevent it from falling off.

[0097] In some embodiments, the blocking member 14 may be an inclined protrusion on the surface of the housing 10, the inclination direction of which gradually moves away from the projection of the socket 11 in the insertion direction. For example, Figure 10 A cross-sectional structure of an anti-dislodgement socket with a blocking element 14 is shown. Figure 10 In the middle position, the adjusting component 50 is in the unlocked position. At this time, the plane of the opening 31 on the anti-disengagement component 30 is parallel to the plane of the socket 11, and the groove 522 on the support component is directly opposite the end of the blocking component 14 away from the socket 11. Figure 11 As shown, the distance between each part of the blocking member 14 and the bottom of the groove 522 in the direction parallel to the plane where the socket 11 is located is defined as the first distance Ln. Then, the first distance L1 at the end of the blocking member 14 away from the socket 11 is just equal to the length of the anti-disengagement member 30, while the first distance of the other parts of the blocking member 14 is less than the length of the anti-disengagement member 30, and the closer to the socket 11, the smaller the first distance.

[0098] In summary, the anti-disengagement socket provided in this application embodiment has an anti-disengagement component 30, a limiting component 40, and an adjusting component 50 installed on the housing 10. When the plug 60 is not inserted into the anti-disengagement socket and the adjusting component 50 is in the unlocked position, the opening 31 of the anti-disengagement component 30 corresponds to the socket 11, so the pin 61 of the plug 60 can be inserted into the socket assembly 20 in sequence through the socket 11 and the opening 31. After the plug 60 is inserted into the anti-disengagement socket, the adjusting component 50 can be operated to move from the current unlocked position to the locking position, and drive the anti-disengagement component 30 and the limiting component 40 to rotate until the inner wall of the opening 31 of the anti-disengagement component 30 jams the pin 61, and the limiting component 40 abuts against the pin 61. Since there is a large friction between the pin 61 and the opening 31 and the limiting component 40, it is difficult to pull out the plug 60 directly, thus reducing the risk that the plug 60 inserted into the anti-disengagement socket may accidentally fall out, and realizing the anti-disengagement function.
