The cable housing assembly 300 is disposed on the housing 100, and is configured to house the power cord 200; the cable housing assembly 300 may be disposed outside the housing 100 or may be disposed inside the housing 100, and in order to ensure the simplicity of the overall appearance of the socket, the cable housing assembly 300 is preferably disposed inside the housing 100.

The cable housing assembly 300 is used for housing the power cord 200 in various manners, and the cable housing assembly 300 can be used for housing the power cord 200 manually, for example, the cable housing assembly 300 comprises a wire spool 310 and a rocker, the wire spool 310 is rotatably mounted on the housing 100, the rocker is connected with the wire spool 310, a user rotates the wire spool 310 by rotating the rocker, and the power cord 200 can be coiled by rotating the wire spool 310, so that the power cord 200 can be housed; as another example, the cable housing assembly 300 includes a wire spool 310 and a driving device, which can drive the wire spool 310 to rotate so that the wire spool 310 can coil the power cord 200, for example, the driving device can be a motor, so that the power cord 200 can be housed; the cable housing assembly 300 is used to house the power cord 200 in a number of ways, which are not shown here.

The limiting assembly 400 is disposed on the housing 100, and is used for relatively fixing the power plug 210 to the housing 100 or releasing the power plug from the housing 100. In this embodiment, the power plug 210 and the housing 100 may be connected by a threaded connection, at this time, the limiting component 400 is a screw, the housing 100 is provided with a threaded hole matched with the screw, and the screw passes through the power plug 210 and is screwed with the threaded hole to fix the power plug 210 on the housing 100.

In another embodiment, the power plug 210 and the housing 100 may be connected by a clamping manner, for example, a clamping groove 210a is provided on either the power plug 210 or the housing 100, and a clamping protrusion is provided on the other, wherein the clamping protrusion is the limiting component 400, and the power plug 210 can be relatively fixed on the housing 100 by matching the clamping protrusion with the clamping groove 210 a. Of course, the form of the spacing assembly 400 for detachably connecting the power plug 210 to the housing 100 is not particularly limited herein.

In the use process of the socket of this embodiment, firstly, a user inserts the power plug 210 on the fixed wall plug (i.e. the plugboard embedded in the wall body, denoted as the fixed wall plug) and conducts the power plug into the circuit, and then inserts and conducts the power plug 210 of the electrical appliance with the plug-in module, so as to supply power to the electrical appliance.

It should be noted that, after the power plug 210 is connected with the housing 100, the pins of the power plug 210 are located on a surface opposite to the jack 100h disposed on the housing 100 and extend out of the housing 100, so that when the socket is in a wall-plug state, the power plug 210 is inserted into the fixed wall in the wall body to be plugged into the jack 100h of the socket, which does not affect the external electrical appliance, and the pins of the power plug 210 can be completely inserted into the jack of the fixed wall in the wall body.

When the power cable of the electrical apparatus is short (for example, the distance between the ideal position of the electrical apparatus and the fixed socket is long, and the power cable of the electrical apparatus is not enough to be directly connected with the fixed socket), the user can operate the limiting assembly 400 to separate the power plug 210 from the housing 100, at this time, the power plug 210 is inserted on the fixed wall (the fixed wall has a certain fixing effect, so that the power plug 210 cannot fall and has a certain anti-pulling property), the user can hold the housing 100 and pull the housing 100, and release the power cable 200 from the cable storage assembly 300 by pulling the housing 100, and continuously pull the housing 100 to a proper position to be converted into a socket with the power cable 200, so that the plug of the electrical apparatus can be plugged into and conducted with the plug-in module.

If the length of the electric connection wire of the electric appliance meets that the plug can be directly plugged into the fixed wall, the user can operate the cable containing assembly 300 to recycle the power line 200, the power line 200 is continuously recycled under the action of the cable containing assembly 300, meanwhile, the user holds the shell 100 to align the power plug 210 plugged into the fixed wall, so that the shell 100 is in butt joint with the power plug 210, and finally the shell 100 is relatively firmly connected with the power plug 210 under the action of the limiting assembly 400, so that the row plug with the power line 200 is converted into the wall plug without the power line 200.

The socket of the present embodiment, the power plug 210 and the housing 100 are detachably connected, so that the socket can be switched between a row of plugs with power lines 200 and a wall plug without power lines 200, the power plug 210 is relatively fixed on the housing 100 by arranging the limit component 400 on the housing 100, and finally the power plug 210 is inserted into a fixed wall on a wall surface to plug a plug of a power supply device into a circuit; when the power line is converted into the cable arranging and inserting, the limiting assembly 400 is operated so that the power plug 210 can be removed from the shell 100, the shell 100 is pulled to be separated from the power plug 210, and meanwhile, the power line 200 is pulled out from the cable accommodating assembly 300 along with the power line, so that the socket can be switched into the cable arranging and inserting; when the wall plug is switched to the wall plug without the power cord 200, the power cord 200 is recovered by the cable containing assembly 300, and finally the power plug 210 is relatively fixed on the housing 100 by the limiting assembly 400. Compared with the existing socket, the socket of the present embodiment can switch between the extension socket with the power cord 200 and the wall socket without the power cord 200, so that the user can flexibly use the socket in different scenarios.

Referring to fig. 3 and 5, in the present embodiment, a housing groove 100a is formed on a surface of the housing 100, a clamping groove 210a is concavely formed on an outer sidewall of the power plug 210, and the limiting assembly 400 includes:

The clamping piece 410 is telescopically arranged on the inner side wall of the accommodating groove 100a, and is used for extending into the clamping groove 210a to form clamping fit with the power plug 210 when the power plug 210 is placed in the accommodating groove 100 a.

In the use process of the socket of the embodiment, when a user needs to use the wall socket without the power cord 200, the power plug 210 can be placed in the accommodating groove 100a and pressed, meanwhile, the clamping piece 410 can retract into the inner side wall of the accommodating groove 100a under the action of the user, when the power plug 210 abuts against the bottom wall of the accommodating groove 100a (i.e. the power plug 210 is placed in place), the clamping groove 210a formed on the outer side wall of the power plug 210 is opposite to the clamping piece 410, the user can operate the clamping piece 410 to enable the clamping piece 410 to extend into the clamping groove 210a, and the clamping piece 410 and the clamping groove 210a form a clamping fit, so that the power plug 210 is relatively fixed on the housing 100.

When the user needs to use the power cord 200 for arranging and inserting, the user can pull the clamping piece 410 out of the clamping groove 210a to release the fixing of the power plug 210, so that the power plug 210 and the housing 100 can be separated, and finally the user pulls the housing 100 to the use position.

In order to ensure that the limiting assembly 400 can better fix the power plug 210 in the accommodating groove 100a, and when the socket is in a wall-plug state, the wall cannot deviate due to unilateral stress of the power plug 210 when being plugged, in this embodiment, the limiting assembly 400 includes two clamping members 410, the two clamping members 410 are respectively slidably arranged on two inner side walls of the accommodating groove 100a, which are oppositely arranged, and can move towards directions close to or far away from each other, two clamping grooves 210a are concavely arranged on two opposite side walls of the power plug 210, the two clamping grooves 210a are in one-to-one correspondence with the two clamping members 410, and the two clamping members 410 can respectively extend into the corresponding clamping grooves 210a under the action of a user so as to limit two opposite sides of the power plug 210, thereby avoiding uneven stress of the power plug 210, and ensuring that the power plug 210 can be better and relatively fixed in the accommodating groove 100a under the action of the limiting assembly 400.

In addition, there are many ways to make the clamping member 410 be telescopically disposed on the inner side wall of the accommodating groove 100a, for example, one end of the clamping member 410 may be exposed on the surface of the housing 100, and the user can manually toggle the clamping member 410 to be located at one end of the housing surface 100 to make the clamping member 410 be telescopically disposed on the inner side wall of the accommodating groove 100 a; for another example, the clamping piece 410 can also automatically stretch and retract in a motor driving mode, a motor and a screw rod are further arranged in the shell 100, an output shaft of the motor is connected with the screw rod, the clamping piece 410 is penetrated with a threaded hole matched with the screw rod in a threaded mode, and the motor works to drive the screw rod to rotate so as to drive the clamping piece 410 to stretch and retract; there are many ways to make the latch 410 be telescopically disposed on the inner sidewall of the accommodating groove 100a, which will not be described in detail herein.

It should be noted that, in order to ensure that the latch 410 can extend into the slot 210a or extend out of the slot 210a in a smaller telescopic stroke, the contour shape of the accommodating slot 100a is adapted to the outer contour shape of the power plug 210, so that the power plug 210 is in clearance fit with the accommodating slot 100a, and thus the latch 410 can extend into the slot 210a or extend out of the slot 210a in a smaller telescopic stroke.

The socket of this embodiment is configured to set a receiving groove 100a on the housing 100 for accommodating the power plug 210, and set a clamping groove 210a on an outer sidewall of the power plug 210 for inserting a clamping piece 410 disposed on an inner sidewall of the receiving groove 100a, so that the power plug 210 is relatively fixed on the housing 100, and is converted into a wall plug without a power line 200, and the clamping piece 410 is pulled out of the clamping groove 210a to release the fixation of the power plug 210, so that the power plug 210 is separated from the housing 100, and finally the housing 100 is pulled to a potential position, so that the socket can be converted into a socket with the power line 200, thereby facilitating flexible use of a user in different environments.

Referring to fig. 6 to 9, in order to facilitate the telescopic arrangement of the clamping member 410 on the inner side wall of the accommodating groove 100a, in this embodiment, a first mounting groove 100b for accommodating the clamping member 410 is concavely formed on the inner side wall of the accommodating groove 100a, and at least a portion of the clamping member 410 is located in the first mounting groove 100b, so that the clamping member 410 can slide along the depth direction of the first mounting groove 100 b.

The spacing assembly 400 further includes:

the first elastic member 420 is located in the first installation groove 100b, one end of the first elastic member 420 is abutted with the bottom of the first installation groove 100b, and the other end is abutted with one end of the clamping member 410 located in the first installation groove 100b, so as to elastically support the clamping member 410 to have a trend of extending into the clamping groove 210 a;

The unlocking component 430 is disposed on the housing 100, and is used for removing the clamping piece 410 from the clamping groove 210a, so that the power plug 210 can be taken out from the accommodating groove 100 a.

It should be noted that, in the embodiment, two clamping members 410 are preferably used to limit two opposite sides of the power plug 210, that is, two opposite inner side walls in the accommodating groove 100a are both concavely provided with the first mounting groove 100b, and the two clamping members 410 limit the power plug 210 together, so that the power plug 210 can be more stably arranged in the accommodating groove 100 a.

The first elastic member 420 may be provided in various forms, and the first elastic member 420 may be a component having elastic deformation capability, such as a spring, a spring plate, or a spring block, and the form of the first elastic member 420 is not particularly limited herein.

The unlocking component 430 is used for removing the clamping piece 410 from the clamping groove 210a in various manners, for example, the unlocking component 430 may include a sliding block, one side of the sliding block is slidably mounted in the first mounting groove 100b and connected with the clamping piece 410, the other side of the sliding block is exposed on the surface of the housing 100, and a user can toggle the sliding block to drive the clamping piece 410 to slide in the first mounting groove 100b, so that when the power plug 210 needs to be taken out from the housing groove 100a, the sliding block can be toggled to enable the clamping piece 410 to be arranged at intervals with the clamping groove 210a, and then the power plug 210 can be taken out;

For another example, the unlocking assembly 430 includes an unlocking rod, a sliding hole is concavely formed on the surface of the housing 100 and is communicated with the first mounting groove 100b, the unlocking rod is slidably mounted in the sliding hole, a sliding track of the unlocking rod is perpendicular to a sliding track of the clamping piece 410, one end of the unlocking rod is exposed on the surface of the housing 100, the other end of the unlocking rod is arranged in a conical shape and passes through the sliding hole to be abutted against the clamping piece 410, thus a user presses the unlocking rod, the unlocking rod slides and can push the clamping piece 410 to slide in the first mounting groove 100b due to the fact that one end of the unlocking rod is conical, so that when the power plug 210 needs to be taken out from the housing 100a, the unlocking rod can be pressed to abut against the clamping piece 410 to enable the clamping piece 410 to be arranged at intervals with the clamping groove 210a, and then the power plug 210 can be taken out; there are many ways in which the unlocking member 430 can be used to drive the latch 410 to slide and remove the latch 410 from the slot 210a, which are not shown.

In the use process of the socket of the embodiment, when a user needs to use the wall socket without the power cord 200, the power plug 210 can be placed in the accommodating groove 100a and pressed, at this time, the clamping piece 410 can retract into the first mounting groove 100b under the action of external force, and meanwhile, the first elastic piece 420 is compressed; after the power plug 210 is pressed in place, the clamping groove 210a on the outer side wall of the power plug 210 is opposite to the clamping piece 410, and meanwhile, under the action of the first elastic piece 420, the clamping piece 410 is pushed into the clamping groove 210a to form a clamping fit with the clamping groove 210a, so that the power plug 210 is relatively fixed on the housing 100.
