The utility model provides a plug which is mainly used for electrically connecting electrical equipment with a power socket, and particularly, a user can operate the plug by one hand and safely and effectively separate the plug from the socket.

As shown in fig. 1 and 2, the plug according to the present utility model includes a housing 100, an ejector 200, and a driving assembly 300, wherein:

the housing 100 includes a main body 101 and a cover plate 102; the main body 101 is internally provided with a conductive terminal 102a, the cover plate 102 is covered at one end of the main body 101, the conductive terminal 102a is partially positioned in the main body 101, and partially penetrates through the cover plate 102, the plug further comprises an ejection piece 200 arranged in the main body 101 and a driving assembly 300 arranged outside the main body 101 and connected with the ejection piece 200, and the ejection piece 200 can be slidably arranged in the cover plate 102 and driven by the driving assembly 300 to reciprocate along the length direction of the conductive terminal 102 a.

Note that, the conductive terminal 102a in the present embodiment is only exemplified by national standards (the conductive terminal 102a is characterized by three flat heads). Of course, in other embodiments, it may be a American standard (featuring a round and flat conductive terminal 102 a), an English standard (featuring three square ends for conductive terminal 102 a), an European standard (featuring two round ends for conductive terminal 102 a), a south African standard plug (featuring three round ends for conductive terminal 102 a), etc. In this embodiment, the specification of the plug may be 10A or 16A, and is not particularly limited.

In the use process of the plug of the embodiment, firstly, the electrical execution standard and model matching of the plug and the socket need to be confirmed; after the preparation work is finished, the surface of the plug provided with the conductive terminal 102a faces the hole of the socket, the position is adjusted, the conductive terminal 102a is pushed into the hole until the conductive terminal 102a is completely inserted into the hole, the electrified copper sheet of the socket is clamped on the conductive terminal 102a to indicate that the plug and the socket are plugged, and at the moment, an electric appliance is successfully connected into a power supply circuit and can be used.

When the electric appliance is not used any more, the user can hold the driving assembly 300 with one hand and operate the driving assembly, and at the moment, the driving assembly 300 drives the ejection member 200 to extend out of the cover plate 102 under the action of external force to be abutted with the surface of the socket; along with the continuous operation of the driving assembly 300 by the user, the driving assembly 300 continuously drives the ejector 200 to extend out of the cover plate 102, in this process, the ejector 200 will jack up the whole housing 100 until the conductive terminal 102a is pulled out of the socket sleeve, i.e. the plug and socket separation is completed, at this time, the user can very easily take away the plug.

The plug of the embodiment adopts the structure that a driving assembly 300 is arranged outside a main body 101 and is used for being connected with an ejection piece 200 arranged in the main body 101, and the ejection piece 200 can reciprocate along the extending direction of a conductive terminal 102a under the driving action of the driving assembly 300; when the conductive terminal 102a needs to be pulled out of the socket, the driving assembly 300 is operated to drive the ejector 200 to move along the extending direction of the conductive terminal 102a, so as to extend out of the cover plate 102 to abut against the surface of the socket to jack up the housing 100, thereby separating the conductive terminal 102a from the socket. Compared with the existing plug, the plug of the embodiment can separate the conductive terminal 102a from the socket by operating the driving assembly 300 in a scheme that one hand is needed to press the socket and the other hand is needed to grasp the plug for pulling out, so that the plug can be pulled out by one hand, safety and effectiveness are realized, and the other hand is released, so that the plug is simple and convenient.

In one embodiment, the drive assembly 300 may be a lever-type drive that drives the ejector 200 out of the cover plate 102.

In another embodiment, the driving assembly 300 can move along the length direction of the conductive terminal 102a while rotating relative to the main body 101. Specifically, the driving assembly 300 is connected to the main body 101 by screw rotation, and the ejector 200 is pushed out of the cover plate 102 to abut against the socket surface by screw rotation, so as to jack up the housing 100, so that the conductive terminal 102a is separated from the socket.

Referring to fig. 2 and 3, in the present embodiment, the driving assembly 300 includes a rotating disc 301, one end of the rotating disc 301 is abutted with the main body 101 and can rotate relative to the main body 101, and a lifting structure 302 matched with the ejector 200 is disposed in the rotating disc 301 for driving the ejector 200 to move. In the present embodiment, the lifting structure 302 may be a chute that is disposed obliquely above the rotating disk 301, but is not limited thereto, and in other embodiments, may be a bar-shaped protrusion that is disposed obliquely above the rotating disk 301.

In the present embodiment, only two pairs of the lifting structure 302 and the ejector 200 are provided correspondingly, but it is needless to say that the number of the lifting structure 302 and the ejector 200 is not particularly limited and may be adjusted accordingly according to the actual situation.

In the plug of this embodiment, under the action of an external force, the rotating disc 301 rotates relative to the main body 101 in a first direction, meanwhile, the lifting structure 302 converts the rotational force of the rotating disc 301 into a pushing force for driving the ejector 200, and the lifting structure 302 pushes the ejector 200 to move along the length direction of the conductive terminal 102a until the ejector 200 extends out of the cover plate 102 to abut against the surface of the socket, so as to jack up the whole housing 100, separate the conductive terminal 102a from the socket, and realize plug extraction by one hand.

When the rotary disk 301 rotates in the second direction relative to the main body 101 (i.e., reversely rotates the rotary disk 301 in the first direction), the lifting structure 302 converts the rotational force of the rotary disk 301 into a tensile force, and pulls the ejector 200 to retract into the main body 101, so that each component of the plug is reset to an initial state, so that the next use by a user is facilitated.

In order to enable the rotating disc 301 to rotate stably relative to the main body 101 during the process of rotating the rotating disc 301, detachment from the main body 101 is avoided, in this embodiment, as shown in fig. 2, an end of the main body 101 abutting against the rotating disc 301 limits the rotating disc 301, and an end of the rotating disc 301 away from the main body 101 is limited by the cover plate 102. In this way, the rotation disk 301 is rotated only with respect to the main body 101 by the engagement of the main body 101 and the cover plate 102, and the separation from the main body 101 is prevented, thereby improving the reliability.

With continued reference to fig. 2, if the rotation angle of the rotation disc 301 is too large (e.g., 360 degrees of rotation) during the rotation of the rotation disc 301 relative to the main body 101, the lifting structure 302 and the ejector 200 may be damaged, which affects the use of the device. Therefore, in the present embodiment, the main body 101 is provided with the first limiting structure 101a, and the first limiting structure 101a is used for limiting the rotation of the rotating disc 301. Note that, in this embodiment, the first limiting structure 101a may be a protrusion disposed opposite to each other, and the specific position may be disposed from the main body 101 toward one end of the driving disc 301, or may be a protrusion from a side wall of the main body 101, which is not particularly limited herein.

The plug of this embodiment is used for limiting the rotation of the rotating disc 301 in a preset stroke (under the premise that the ejection member 200 can jack up the housing 100 and separate the conductive terminal 102a from the socket sleeve) through the first limiting structure 101a, so as to avoid the overlarge rotation amplitude of the rotating disc 301, and damage the lifting structure 302 and the ejection member 200, thereby improving the overall reliability.

As shown in fig. 3, the elevating structure 302 includes a body 302a extending in the circumferential direction of the rotating disk 301 and a guide groove 302b provided obliquely to the body 302 a; the ejector 200 is provided with a guide portion 200a that can be inserted into the guide groove 302b. In the present embodiment, the guide groove 302b is merely provided in the main body 302 a. Of course, in other embodiments, the guide groove 302b may be disposed on the ejector 200, specifically, the guide portion 200a is in a strip shape, the strip-shaped guide portion 200a is spirally disposed along the side wall of the body 302a, and the ejector 200 is provided with the guide groove 302b corresponding thereto.

In the use process of the plug according to the embodiment, the user operates the rotating disc 301 to rotate relative to the main body 101, the guide groove 302b provided on the main body 302a guides the guide portion 200a, at this time, the guide groove 302b slides relative to the guide portion 200a, and since the guide groove 302b is obliquely provided on the main body 302a, the groove wall of the guide groove 302b pushes the guide portion 200a to push the ejector 200 to move along the length direction of the conductive terminal 102a, so that the ejector 200 extends out of the cover plate 102 to contact with the surface of the socket, and the whole housing 100 is pushed up to separate the conductive terminal 102a from the socket. Thus, the user can easily pull out the plug by one hand, which is quite convenient.

In one embodiment, the body 101 is provided with an opening for avoidance of the lifting structure 302.

With continued reference to fig. 3, in this embodiment, the lifting structure 302 may be used to avoid the side wall of the main body 101, specifically, an avoiding portion 301b is formed between the main body 302a and the inner side wall of the rotating disc 301, where the avoiding portion 301b is used to avoid the side wall of the main body 101. In this way, the side wall of the main body 101 may extend into the avoiding portion 301b, so as to implement the limitation of the rotating disc 301 in the foregoing embodiment. Meanwhile, in the rotating process of the rotating disc 301, the side wall of the main body 101 can guide the rotation of the rotating disc 301, so that the rotating disc 301 cannot move horizontally relative to the main body 101, the limiting is reliable, and the overall structure of the plug is compact and reasonable.

In order to enable the ejector 200 to slidably extend or retract from the cover plate 102 stably and reliably, referring to fig. 3 and 4, in the present embodiment, the ejector 200 is provided with a sliding chamber 200b extending along the length thereof; the main body 101 is provided with a guide post 101b protruding from a side facing the cover plate 102, the guide post 101b is inserted into the sliding cavity 200b, and the guide post 101b is used for guiding the ejector 200. In the present embodiment, the guide post 101b is provided on the main body 101 on the side facing the panel. Of course, in other embodiments, a sliding cavity 200b may be provided on a side of the main body 101 facing the panel, and in particular, the ejector 200 may be slidably installed in the sliding cavity 200 b.

In the use process of the plug of this embodiment, the ejector 200 is driven by the rotating disc 301 to move along the length direction of the conductive terminal 102a, and meanwhile, the guide post 101b disposed on one side of the main body 101 guides the movement of the ejector 200, so that the ejector 200 can be prevented from shaking and swinging in the extending or retracting process, the ejector 200 is ensured to stably jack the housing 100, and the jacking stability and reliability are improved.

In order to facilitate the user to operate the rotating disc 301, the volume of the rotating disc 301 may be increased, so that the rotating disc 301 protrudes more relative to the main body 101, specifically, referring to fig. 1 to 6, in this embodiment, the driving assembly 300 further includes a driving disc 303, the driving disc 303 is sleeved with the main body 101 and the rotating disc 301, for increasing the circumferential volume of the rotating disc 301, a supporting portion 303a is disposed on an inner side wall of the driving disc 303, a mounting groove 301a for accommodating the supporting portion 303a is disposed on an outer side wall of the rotating disc 301, and in a rotation process, the driving disc 303 may drive the rotating disc 301 to rotate under the cooperation of the supporting portion 303a and the mounting groove 301 a. In the present embodiment, the driving disk 303 is merely provided with the abutting portion 303 a. Of course. In other embodiments, the abutting portion 303a may be provided on the rotating disk 301, and the corresponding mounting groove 301a may be provided on the driving disk 303, and the present utility model is not limited thereto.

The number of the abutting portions 303a and the number of the mounting grooves 301a may be one pair or two pairs, and may be adjusted according to the actual situation, and is not particularly limited.

The driving disc 303 is sleeved outside the rotating disc 301, so that the circumferential volume of the rotating disc 301 is increased, namely, the operable part is increased, and in the driving process, the abutting part 303a and the mounting groove 301a are adopted to realize transmission, so that a user can operate the rotating disc 301 more easily, and the use experience is improved.

In one embodiment, in order to make it more convenient for the user to operate the driving disk 303, a friction portion is provided on the outer side wall of the driving disk 303; the friction portion is in the form of a bar, and a plurality of friction portions are provided at intervals around the circumference of the drive plate 303. In addition, the friction part may be made of an elastic material, such as rubber, silica gel, etc., but is not limited thereto. In this way, the user has a good touch feeling when operating the driving disk 303, and simultaneously increases the friction force, so that the user can easily rotate the driving disk 303.

In the process of propping and lifting the ejector 200 against the surface of the socket, the ejector 200 can lift the housing 100 to move away from the socket, if the distance between the driving disc 303 and the socket remains unchanged relatively, a downward force is generated to act on the ejector 200, and the user needs to release the applied pressure slightly to separate the plug from the socket, so that the operation of the user is inconvenient. Therefore, to further increase the efficiency of separating the plug from the socket, in the present embodiment, as shown in fig. 3, the rotating disc 301 includes a first reset element 304, the first reset element 304 is disposed in the mounting groove 301a, one end of the first reset element 304 abuts against the bottom of the mounting groove 301a, and the other end abuts against one end of the abutting portion 303a, so as to reset the driving disc 303 along the length direction of the conductive terminal 102 a. It should be noted that, the first restoring member 304 in the present embodiment may be a spring, a shrapnel, etc., but is not limited thereto.

When the plug of the embodiment needs to be separated from the socket, the driving disc 303 is rotated, so that the ejector 200 extends out of the housing 100 to be abutted against the surface of the socket; during the process of lifting the housing 100 by the ejector 200, other components (e.g., the main body 101, the rotating disc 301, etc.) may move a certain distance with respect to the driving disc 303, while compressing the first restoring member 304. In this way, the reaction force generated during the process of the ejector 200 ejecting the housing 100 is eliminated, so that the plug can be more easily pulled out from the socket.

After the plug is removed from the socket, the first reset element 304 pushes the driving disc 303 to move towards the end far away from the cover plate 102, so that the driving disc 303 is quickly reset to the initial position, and the next use of the user is facilitated.

Referring to fig. 2 and 5, in this embodiment, a second limiting structure 103 is further disposed on an outer sidewall of the main body 101, where the second limiting structure 103 contacts with an end of the driving disc 303 opposite to the cover plate 102, and is used for limiting the driving disc 303, and the second limiting structure 103 in this embodiment is in a rib shape and extends around a circumferential direction of the main body 101;

in the resetting process, the first resetting piece 304 pushes the driving disc 303 to move in a direction opposite to the cover plate 102, and when the driving disc 303 is pushed to a preset position, the second limiting structure limits the driving disc 303 to move in a direction away from the cover plate 102. In this way, the first reset element 304 is matched with the second limit structure 103, so that the reaction force generated in the process of jacking the shell 100 by the ejection element 200 is eliminated, and meanwhile, the driving disc 303 is stably installed outside the rotating disc 301.

When the conductive terminal 102a is taken out from the hole of the socket, the ejector 200, the rotating disc 301, the driving disc 303 and other components are still in the triggered state, and the components need to be restored to the original state before the next use, which is troublesome if the user manually resets the components. Thus, as shown in fig. 4, in the present embodiment, the plug further includes a second reset element 401, one end of the second reset element 401 is provided on the bottom wall of the main body 101, the other end is connected to the rotating disc 301, and the second reset element 401 is used to reset the rotating disc 301 to the initial position. In this embodiment, the second restoring member 401 may be a torsion spring, but is not limited thereto.

When a user operates the plug to be separated from the socket, the rotating disc 301 drives the other end of the second reset piece 401 to rotate by a certain angle by taking the second reset piece 401 as a center under the action of external force, and simultaneously compresses the second reset piece 401; when no external force is applied to the rotating disc 301, the second reset element 401 generates a reverse torque to drive the rotating disc 301 and the driving disc 303 to rotate reversely, and the rotating disc 301 drives the ejector element 200 to retract into the main body 101. In this way, after the user operates the plug to be separated from the socket, the plug can be automatically reset from the trigger state to the initial state under the action of the second reset member 401, so that the next use of the plug by the user is convenient.

The above description of the preferred embodiments of the present utility model should not be taken as limiting the scope of the utility model, but rather should be understood to cover all modifications, variations and adaptations of the present utility model using its general principles and the following detailed description and the accompanying drawings, or the direct/indirect application of the present utility model to other relevant arts and technologies.
