The terms of orientation, such as "up", "down", "top", "bottom", "side", etc., referred to in the embodiments of the present invention are all based on the corresponding orientation of the socket shown in fig. 1 and 2, wherein the orientation of the face cover is "up" or "top", and the orientation of the fixing base is "down" or "bottom". Also, the direction of the insertion movement of the plug into the socket is defined as downward, and the direction of the extraction movement of the plug from the socket interior is defined as upward. These terms are used in the embodiments of the present invention only for the purpose of describing structures and relationships between the structures more clearly, and are not intended to describe absolute orientations.

It should be noted that the socket includes a functional module inside, the functional module includes a plug bush assembly, the plug bush assembly includes a plug bush and a protection door located at the top of the plug bush, and the whole body formed by the plug bush and the protection door in the plug bush assembly is collectively referred to as the plug bush assembly in the embodiment of the present invention.

In the socket that the anti-plug that correlation technique provided drops, still additionally arranged the unblock subassembly simultaneously to the anticreep subassembly, the unblock subassembly is including being located the button part on the socket panel and the unblock part that links to each other with the anticreep subassembly in the socket inside, and through pressing the button part, the unblock part can drive the downward displacement of anticreep subassembly, and then realizes the unblock to the plug.

To solve the technical problems in the related art, an embodiment of the present invention provides a socket, as shown in fig. 1 and 2, including: the device comprises a shell 1, a movable cover part 2, a plug bush component 3, a retaining component 4 and a telescopic support 5 which are positioned inside the shell 1.

Wherein, the face cover 110 of the housing 1 has a through hole 111, the movable cover member 2 has a receptacle 20, the movable cover member 2 can reciprocate between a first position and a second position along the through hole 111; a telescopic support 5 is located between the movable cover 2 and the housing 1 for supporting the movable cover 2; the movable cover member 2 is configured to be pressed by a plug to move downward and to be locked at the second position when the plug pin of the plug is inserted into the socket 31 of the socket assembly 3, and the movable cover member 2 is released from being pressed downward and to move upward to the first position by the expansion of the telescopic supporter 5.

When the plug is not inserted into the socket, the movable cover member 2 is stabilized in the first position by the support of the telescopic support member 5. When a plug is inserted into the socket and the movable cover member 2 is pressed downward, the movable cover member 2 can move downward from the first position to the second position and press the telescopic supporting member 5 until the plug pin of the plug is inserted into the plug bush 31 of the plug bush assembly 3, the movable cover member 2 is locked at the second position, and the telescopic supporting member 5 is compressed.

When the plug needs to be pulled out, the plug in the power-taking state is continuously pressed, the movable cover part 2 continuously moves downwards from the second position, therefore, the movable cover part 2 is unlocked by pressing downwards, the telescopic supporting part 5 is expanded and reset, and the movable cover part 2 is driven to move upwards to the first position. In particular, in this process, the upward movement of the movable cover 2 pushes the plug upward, so that the plug is easily removed from the socket 31.

In the embodiment of the present invention, as further seen in fig. 3 and 7, the anti-falling off component 4 is disposed between the movable cover 2 and the socket 31, and has an opening 4201 facing the socket 31 and the receptacle 20 and two movable locking blocks 41 respectively located at two opposite sides of the opening 4201; as can be seen from fig. 6, the movable cover 2 is provided with two first guide surfaces 220 on the side facing the retaining member 4.

The retaining member 4 is configured such that when the movable cover 2 moves downward, the two first guide surfaces 220 abut and drive the two movable locking pieces 41 to move closer to each other, and when the movable cover 2 is locked at the second position, the two first guide surfaces 220 fix the two movable locking pieces 41 to clamp the latch.

When inserting a plug into the jack 20, the movable cover 2 drives the first guide surface 220 abutting against the movable locking piece 41 to move downward, and further drives the movable locking piece 41 to move gradually from the lower end to the upper end of the first guide surface 220, so that the distance between the two movable locking pieces 41 gradually decreases. Until the plug pin is inserted into the plug bush 31, the distance between the two movable locking blocks 41 reaches the minimum, the movable cover member 2 is locked at the second position, and the two first guide surfaces 220 further abut against and fix the two movable locking blocks 41 to clamp the plug pin, so that the plug pin is effectively prevented from loosening.

When the plug needs to be pulled out, the plug is pressed again, the movable cover component 2 drives the first guide surface 220 of the movable cover component to move upwards, the first guide surface 220 gradually releases the movable locking block 41, the bolt is not locked by the movable locking block 41 any more, and the plug is pulled out smoothly.

In summary, in the socket provided in the embodiment of the present invention, the movable cover 2 and the anti-falling off assembly 4 cooperate with each other, and the up-and-down movement of the first guide surface 220 on the movable cover 2 is used to control the movement of the movable locking block 41 between the locking position and the releasing position, so as to lock or release the plug, thereby achieving the purpose of preventing the plug in the power-taking state from being released. Because the up-and-down motion of activity cover spare 2 can be operated through pressing the plug, like this, when extracting the plug, can unblock the bolt through the one hand plug of pressing, simultaneously, the top pushes away the plug when activity cover spare 2 upward movement, can assist the plug to extract from plug bush subassembly 3, and this makes the extraction operation of plug more convenient, and labour saving and time saving more.

In the embodiment of the present invention, the movable lid member 2 is configured to be locked by being pressed, and unlocked by being pressed again. In some examples, as shown in fig. 4, a cooperating heart-shaped groove repositioner 6 is provided between the movable cover 2 and the housing 1. Heart-shaped groove repositioner 6 is common in the art and comprises a heart-shaped groove structure, which has the characteristic of being locked by pressing and unlocked by pressing again.

The heart-shaped groove restorer 6 comprises a pressing type self-locking buckle and a clamping hook which are adaptive to each other, the clamping hook can be clamped into the pressing type self-locking buckle through pressing, and the clamping hook can be pressed again to enable the clamping hook to be separated from the pressing type self-locking buckle. In the embodiment of the present invention, the heart-shaped groove restorer 6 includes a first locking block 61 and a second locking block 62 which are matched with each other, so that one of the first locking block 61 and the second locking block 62 is a pressing type self-locking buckle, and the other is a hook. For example, fig. 4 shows that the first locking block 61 is a hook and the second locking block 62 is a push-type self-locking buckle.

As shown in fig. 4, the movable lid member 2 includes a lid member body 21, a first lock block 61 is attached to an outer wall of the lid member body 21, a second lock block 62 is fixed inside the housing 1, and the first lock block 61 is positioned right above the second lock block 62.

In the embodiment of the present invention, when the movable cover 2 moves downward to the second position, the first locking block 61 is inserted into the locking hole of the second locking block 62 to achieve the locking, so that the movable cover 2 is locked at the second position. When the plug is pressed again, the movable cover part 2 drives the first locking block 61 to move downwards, the first locking block 61 and the second locking block 62 are unlocked, and the movable cover part 2 is unlocked.

In some examples, as shown in fig. 5, the cover body 21 includes a top plate 211 having the insertion hole 20 and a side wall 212, the side wall 212 surrounding the periphery of the top plate 211 and being located below the top plate 211. The first lock block 61 is connected to the lower side of the side wall 212, and the second lock block 62 may be located right below the first lock block 61.

Further, as shown in fig. 5, the lower portion of the side gusset 212 is provided with a groove structure 2120, and the first locking block 61 is located in the groove structure 2120, so that the first locking block 61 is embedded in the side gusset 212 instead of protruding below the side gusset 212. The recess formation 2120 can also accommodate the second locking block 62 such that the second locking block 62 and the first locking block 61 snap fit within the recess formation 2120. By providing the groove structure 2120, the arrangement of the two locking blocks does not increase the thickness of the socket.

Further, as shown in fig. 6, the lid body 21 further includes a bottom plate 213, and the bottom plate 213 is connected to the bottom of the side wall 212, so that the lid body 21 forms an inner cavity capable of accommodating the coming-off prevention assembly 4. It will be appreciated that the bottom plate 213 has at least one interference-preventing hole therein to allow the insert 31 in the insert assembly 3 to pass therethrough to below the lid body 21.

The following describes an exemplary manner of driving the movable lock piece 41 with respect to the movable lid member 2:

in some implementations, as can be seen from fig. 3 and 6, two guide blocks 22 protruding downwards are disposed on the inner wall of the movable cover 2, the two guide blocks 22 are respectively located at two opposite sides of the insertion hole 20, and each guide block 22 has the above-mentioned first guide surface 220.

In the embodiment of the present invention, the movable locking blocks 41 and the guide block 22 are disposed in two opposite directions, the two movable locking blocks 41 are opposite at intervals, and the latch is inserted into the gap between the two movable locking blocks 41. Accordingly, the two guide blocks 22 are respectively located at opposite sides of the corresponding insertion hole 20, and the interval between the first guide surfaces 220 of the two guide blocks 22 gradually increases in the insertion direction of the plug.

As shown in fig. 6, the top end of the guide block 22 is coupled to the top plate 211, and the first guide surface 220 is disposed on a side wall of the guide block 22 facing the insertion hole 20 such that the first guide surface 220 is in contact with a side wall of the latch penetrating the insertion hole 20.

Through the cooperation of the two movable locking blocks 41 and the two guide blocks 22 which are symmetrically arranged, the locking force of the bolt is improved, the locking force is symmetrically distributed on the bolt, and the bolt is prevented from being damaged in the long-term locking process.

The first guide surface 220 is obliquely arranged in such a direction that the upper end of the first guide surface 220 is closer to the latch pin located in the insertion hole 20 than the lower end thereof by the inclination of the first guide surface 220. The width of the gap between the first guide surface 220 and the plug pin is gradually increased along the plug-in direction of the plug (i.e. the distance between the two first guide surfaces 220 is gradually increased), and the width of the gap between the first guide surface 220 and the plug pin is gradually decreased along the plug-out direction (i.e. the distance between the two first guide surfaces 220 is gradually decreased).

When inserting the plug into the jack 20, the movable cover member 2 drives the two first guide surfaces 220 to move downward, and further drives the two movable locking pieces 41 to move gradually from the lower ends to the upper ends of the first guide surfaces 220, and the distance between the two movable locking pieces 41 decreases gradually. Until the bolt is inserted into the plug bush 31, the movable locking pieces 41 move to contact with the upper ends of the first guide surfaces 220, the distance between the two movable locking pieces 41 reaches the minimum, at this time, the two movable locking pieces 41 clamp the bolt, and meanwhile, the movable cover member 2 is locked at the second position, so that the two first guide surfaces 220 on the movable cover member clamp and fix the two movable locking pieces 41, and the plug is effectively prevented from being loosened.

Further, as shown in fig. 6, a reinforcing structure 214 is further connected to the inner wall of the cap body 21, and the guide block 22 is supported by the reinforcing structure 214 to ensure that the guide block 22 obtains sufficient supporting strength to avoid deformation due to the pressing of the movable locking block 41.

The reinforcing structure 214 is, for example, a frame body (e.g., a rectangular frame), the top end of the frame body is connected with the bottom wall of the top plate 211, the guide block 22 is located inside the frame body, and the side wall of the guide block 22 facing away from the insertion hole 20 is connected with the inner wall of the frame body at the corresponding position.

It is understood that the reinforcing structure 214 has an interference preventing structure to prevent the reinforcing structure 214 from interfering with the anti-slip-off assembly 4 when the movable cover 2 moves downward.

The connection between the cap body 21, the guide block 22 and the reinforcing structure 214 includes, but is not limited to: integrally molded, bonded, welded, screwed, etc., such as by integrally molding the cover body 21, the guide block 22, and the reinforcing structure 214.

In the embodiment of the present invention, the movement mode of the movable locking piece 41 may be a rolling type or a sliding type, that is, the movable locking piece 41 may include a rolling type locking piece or a sliding type locking piece.

For the rolling lock, the movable lock 41 is, for example, a cylinder (see fig. 7), a sphere, an ellipsoid, etc.; for the sliding lock, the movable lock 41 is configured as a wedge, and its wedge surface is adapted to the first guide surface 220 and the optional second guide surface 4203 and is in surface-to-surface contact.

In some examples, the movable locking block 41 according to the embodiments of the present invention is a cylinder with a simple structure, which not only makes the movement of the movable locking block 41 smoother, but also is beneficial to obtain a greater locking force between the movable locking block 41 and the latch.

In some examples, the surface of the movable locking piece 41 has a rough structure including, but not limited to: jagged, granular, etc. The friction force between the movable locking block 41 and the bolt in the locking state can be increased through the rough structure, and then stronger locking force can be obtained.

In some implementations, as shown in fig. 7, anti-drop assembly 4 further includes: the support body 42, the support body 42 has an opening 4201 and two track grooves 4202 located on both sides of the opening 4201, each track groove 4202 is used for receiving an end of a corresponding movable lock block 41, and when the movable cover 2 moves downward, the first guide surface 220 contacts and drives the movable lock block 41 to move in the track groove 4202.

As shown in fig. 7, the anti-falling-off assembly 4 provided by the embodiment of the present invention includes two movable locking pieces 41 symmetrically arranged, and accordingly, the number of the track grooves 4202 is four.

The support body 42 is provided to support the movable locking piece 41, so that the movable locking piece 41 is limited at a specific position inside the socket. The track slot 4202 is configured to only allow the movable lock block 41 to move between the position of locking the latch and the position of releasing the latch without movement in other directions, thereby limiting the path of movement of the movable lock block 41.

The other portion of the movable lock block 41 except for the end portion is exposed to the opening 4201, and opposite sides of the exposed portion are in contact with the first guide surface 220 and the plug pin, respectively.

In some examples, as shown in fig. 7, the support body 42 includes: the top cover 421 and the base 422 are connected, the top cover 421 and the base 422 are both provided with openings 4201, and both sides of the top cover 421 located at the openings 4201 are respectively provided with a caulking groove, so that top walls opposite to the caulking grooves on the caulking groove and the base 422 are matched to form a track groove 4202. Two ends of the movable locking block 41 are respectively embedded into the corresponding track grooves 4202, the top of the movable locking block 41 is in contact with the top wall of the embedding groove, and the bottom of the movable locking block 41 is in contact with the top wall of the base 422, so that the movable locking block 41 is limited.

The connection between the top 421 and the bottom 422 includes, but is not limited to: clamping, bonding, screwing, etc., for example, the top cover 421 and the base 422 are connected by the following clamping methods:

as shown in fig. 7, the top 421 includes: the cap comprises a cap body 4211 and two side connecting plates 4212 connected with two opposite ends of the cap body 4211, wherein one ends of the two side connecting plates 4212 far away from the cap body 4211 are provided with buckles. The base 422 is flat, so that the cover body 4211 is lapped on the top wall of the base 422, the inner side walls of the two side connecting plates 4212 are respectively abutted against the corresponding side walls of the base 422, and the buckles on the side connecting plates 4212 are matched and clamped with the corresponding positions on the bottom wall of the base 422.

With respect to the opening 4201 provided on the top cover 421, as shown in fig. 7, the opening 4201 extends through the cover body 4211 and the upper portions of the two side coupling plates 4212 in the horizontal direction, so that the opening 4201 provided on the top cover 421 can not only accommodate a latch but also prevent interference with the guide block 22 on the movable lid 2, ensuring that the guide block 22 can enter the opening 4201 of the top cover 421 to drive the movable lock block 41 to move. The opening 4201 on the base 422 may be designed to receive only a pin.

In some implementations, as shown in fig. 7 and 8, each track groove 4202 has a second inclined guide surface 4203 on the bottom wall thereof, and the two movable locking pieces 41 are respectively located on the corresponding second guide surfaces 4203 and move away from each other in an inclined direction, that is, the second guide surfaces 4203 enable the released movable locking pieces 41 to automatically move from the locking position of the locking latch to the releasing position of the releasing latch.

The inclination direction of the second guide surface 4203 coincides with the inclination direction of the first guide surface 220, and the highest point of the second guide surface 4203 is closer to the latch pin located in the receptacle 20 with respect to the lowest point thereof (wherein fig. 8 shows that the movable lock piece 41 is located at the highest point of the second guide surface 4203).

When the latch is not inserted, the movable lock block 41 automatically moves to the lowest point of the second guide surface 4203 by its own weight, and the lowest point of the second guide surface 4203 corresponds to the release position of the movable lock block 41, so that there is a maximum distance between the movable lock block 41 and the latch, which facilitates smooth insertion of the latch, when the latch is inserted into the socket 31, the first guide surface 220 on the movable cover 2 drives the movable lock block 41 to move gradually toward the direction close to the highest point of the second guide surface 4203 until the movable lock block 41 moves to the highest point of the second guide surface 4203 to lock the latch, wherein the highest point of the second guide surface 4203 corresponds to the locking position of the movable lock block 41.

When it is necessary to remove the latch from the socket 31, the movable cover 2 moves upward to release the movable lock piece 41, and the movable lock piece 41 automatically moves again to the lowest point of the second guide surface 4203 by its own weight. For example, the movable locking pieces 41 are symmetrically arranged in two, so that when the two movable locking pieces 41 are both at the lowest point of the second guide surface 4203, the distance between the two movable locking pieces 41 is maximized, that is, the two movable locking pieces 41 are in the fully unfolded state, which is particularly advantageous for reducing the friction between the movable locking pieces 41 and the latch during the plugging and unplugging movement.

If the bottom wall of the track groove 4202 is made to be a plane, the two movable locking pieces 41 cannot move freely on the plane, it is difficult to maximize the distance between the two movable locking pieces 41, and the two movable locking pieces 41 can only be in a released state and cannot be fully unfolded, which increases the friction between the moving bolt and the movable locking pieces 41.

It can be seen that, in the embodiment of the present invention, the inclined second guide surface 4203 is provided to support the movable locking piece 41, which is beneficial to reduce the friction between the moving bolt and the movable locking piece 41, so that the inserting and pulling process of the bolt is smoother.

In addition, when the movable lock block 41 is in the locking position, the upper portion of the movable lock block abuts against the first guide surface 220, the lower portion of the movable lock block abuts against the second guide surface 4203, and the first guide surface 220 and the second guide surface 4203 have the same inclination direction and are complementary to each other, so that the distribution of the locking force to the movable lock block 41 is more balanced, which is beneficial to improving the locking stability of the movable lock block 41.

As described above, the support body 42 includes: and a top cover 421 and a base 422 connected to each other, wherein the top cover 421 and the base 422 are respectively provided with a caulking groove at both sides thereof, such that the caulking groove and a top wall of the base 422 opposite to the caulking groove cooperate to form a track groove 4202, such that the track groove 4202 is formed between the top cover 421 and the base 422, and the second guide surface 4203 is located on the top wall of the base 422 facing the top cover 421, that is, the second guide surface 4203 is directly formed on the top wall of the base 422.

As designed above, molding of the track groove 4202 and the second guide surface 4203 is made easier, which can simplify the manufacturing process of the support body 42.

In some implementations, as shown in fig. 10, the receptacle further includes: and the elastic support 7, wherein the elastic support 7 is configured to elastically support the anti-dropping component 4.

In some examples, the number of the elastic supporting members 7 is two or more, and the two or more elastic supporting members 7 are symmetrically arranged below the supporting body 42 to provide stable support to the supporting body 42. For example, the elastic support members 7 are arranged in two, respectively connected to opposite sides of the bottom wall of the supporting body 42.

When the plug is not inserted, the anti-falling component 4 is supported by the elastic supporting piece 7 to be stable at the initial position, when the plug is inserted into the plug bush 31, based on the friction force between the movable locking block 41 and the plug pin, the anti-falling component 4 can move downwards with the plug pin moving downwards by a small distance, so that even if the movable cover component 2 moving downwards enables the first guide surface 220 to be locked with the plug pin in advance, the plug pin can still be guaranteed to move downwards after being locked in advance, the stroke of inserting the plug pin into the plug bush 31 is guaranteed to be in place, namely, the plug pin is guaranteed to be inserted in place, and the problem of virtual insertion of the plug pin is avoided.

It can be seen that elastic supporting element 7 not only can ensure that anti-disengaging assembly 4 makes movable locking block 41 and guide block 22 form contact pressure in the use process, but also can make anti-disengaging assembly 4 have descending activity space simultaneously, so that the socket has a larger fault-tolerant space when there is a size deviation in the unblock bolt or bolt.
