Next, the structure of the plug assembly of the present application is explained and explained with reference to fig. 1 to 20.

As an example, as shown in fig. 1, the plug assembly of the present application includes a housing 101 having an accommodating space therein. The shape of the housing 101 can be set as appropriate according to actual needs, and may be, for example, square, circle, ellipse, polygon or other irregular shapes. It is worth mentioning that in the figures of the present application only the first side of the housing 101 is shown, but it should be understood that the complete housing further comprises e.g. a bottom shell or the like, which is combined with the cover of the first side of the housing 101 to form a housing.

The housing 101 is usually made of an insulating material, including but not limited to plastics, such as ABS plastic, PC, etc., and the insulating material and the flame retardant material are used to increase the flame retardant temperature of the housing 101 and further enhance the safety of the housing 101, which is not limited to the above materials.

The housing 101 has therein an accommodating space for accommodating a circuit board (e.g., a PCB board), and various circuit structures and devices, etc., provided on the circuit board, which are required for realizing, for example, a plug assembly as a power adapter or a charger. When the plug assembly is a power adapter, it can have both functions of an adapter and a charger.

Illustratively, the plug assembly of the present application further includes a pin 102, a first end of the pin 102 is connected with the first side of the housing 101, and a second end of the pin 102 is disposed outside the housing 101, wherein the number of the pins 102 may be two or three, and the pin 102 may include pins 102 conforming to safety standards of various countries, for example, pins 102 conforming to safety standards of countries such as china, the united states, japan, and the united kingdom. In the present embodiment, the structure of three pins 102 disposed at intervals is mainly taken as an example, but it should be noted that the structure of the pins 102 is not limited to the above structure, and other suitable structures may be adopted.

In one example, the plug assembly of the present application further includes an insulating fixing pin 103 located outside the pin 102, a first end of the insulating fixing pin 103 is connected to the first side of the housing 101, when the pin 102 is inserted into the first socket, a part of the insulating fixing pin 103 is pluggable to a jack (for example, a ground wire hole of the second socket or other suitable holes) of the second socket outside the first socket, so as to enhance contact stability between the plug assembly and the socket during use, avoid a problem that the plug assembly drops from the socket, ensure normal operation of an electrical appliance connected to the plug assembly, and further improve user experience and safety and reliability.

Optionally, the insulating fixing pin 103 is made of an insulating material, such as plastic, rubber, etc., so that the insulating fixing pin 103 only plays a fixing role and avoids electrical connection with other circuits.

The insulating fixing foot 103 may be connected with the first side of the housing 101 in any suitable manner, such as fixedly connected, rotatably connected, detachably connected, etc., and due to the limitation of the wall-mounted structure, in some cases, another socket is not provided outside the first socket into which the pin 102 is inserted, or another socket outside the first socket does not have a ground wire hole or a socket corresponding to the fixing foot, so the insulating fixing foot 103 of the present application may also be rotatably connected with the first side of the housing 101, the insulating fixing foot 103 rotates to the extended position when needed, and the insulating fixing foot 103 is in the retracted position when not needed, so as to avoid obstructing the insertion of the pin 102 into the socket.

Although the present application mainly uses one insulative fixing pin 103 as an example, it is understood that the plug assembly may further include a plurality of insulative fixing pins 103, and the insulative fixing pins 103 may correspond to a plurality of insertion holes of the second socket, if necessary. Herein, the shape and size of the insulating fixing foot 103 are configured to match the size and shape of the insertion hole to be inserted, for example, the insulating fixing foot 103 is substantially cylindrical, and the second end surface of the cylindrical shape may be a curved surface, and the size of the curved surface matches the size of the ground hole.

Two implementations of the insulating fixing foot rotatably connecting the first side of the housing will be described below, but it is understood that the following description is only by way of example, and that other suitable connection means may be applied to the present application.

In a first example, as shown in fig. 1 to 4, the plug assembly further includes a rotating shaft 1061 connected to the insulating fixing foot 103, a first end of the insulating fixing foot 103 is rotatably connected to the housing through the rotating shaft 1061, and the insulating fixing foot 103 is configured to be rotatably switched between the retracted position and the deployed position through the rotating shaft 1061.

Alternatively, the angle between the deployed position and the stowed position is substantially 90 degrees, as shown in fig. 2, when the insulating securing leg 103 is in the stowed position, the axial direction of the insulating securing leg 103 is substantially parallel to the outer surface of the first side of the housing, and when the insulating securing leg 103 is in the open position, as shown in fig. 1, the axial direction of the insulating securing leg 103 is substantially perpendicular to the outer surface of the first side of the housing, and when the insulating securing leg 103 is in the open position, the second end of the insulating securing leg 103 is located outside of the housing.

Optionally, a face of the housing that is connected to the insulating fixing foot 103 (i.e., a first side of the housing) is provided with a receiving slot 104, and the receiving slot 104 is configured to receive the insulating fixing foot 103 in the retracted position, so as to prevent the insulating fixing foot 103 in the open position from interfering with the insertion of the pin into the jack. On the premise that the receiving groove 104 can receive the insulating fixing pin 103, the shape and size of the receiving groove 104 can be set reasonably according to actual needs.

Alternatively, as shown in fig. 3, the rotating shaft 1061 is disposed at a first end of the insulating fixing leg 103 and protrudes to two sides of the insulating fixing leg 103, a bracket is disposed inside the housing, and the rotating shaft 1061 is rotatably fixed to the bracket. The bracket can be two brackets arranged at intervals, and the top end of the bracket is arranged in an inwards concave arc shape to be matched with the rotating shaft 1061.

Optionally, a limiting structure 1062 is further fixedly connected to at least one end of the rotating shaft 1061, the limiting structure 1062 is configured to limit the rotation of the insulating fixing foot in the retracted position or the deployed position, and a radial cross-sectional shape of the limiting structure 1062 is a rectangle, which may be a rectangle or a square. Optionally, the two ends of the rotating shaft 1061 may be provided with the limiting structures 1062, or only one end of the rotating shaft 1061 may be provided with the limiting structures 1062, which may be set reasonably according to actual needs.

Optionally, the plug assembly further includes a pressing plate 107, the pressing plate 107 is located inside the housing 101 and covers the bracket, wherein the bracket is fixedly connected to the inner surface of the first side, the rotating shaft 1061 is rotatably fixed on the bracket through the pressing plate 107, and the limiting structure 1062 is located between the pressing plate 107 and the inner surface of the first side of the housing 101, for example, between the pressing plate 107 located outside the bracket and the inner surface of the first side of the housing 101, when the insulating fixing foot 103 is in the extended position or in the retracted position, two parallel first surfaces and second surfaces of the limiting structure 1062 are parallel to the inner surface of the first side of the housing 101, and the first surfaces and the second surfaces are perpendicular to the end surface of the rotating shaft 1061, optionally, the distance between the pressing plate 107 and the inner surface of the first side of the housing 101 may be greater than or equal to the distance between the first surfaces, and the distance between the pressing plate 107 and the inner surface of the first side of the housing 101 is smaller than the radial section of the limiting structure 1062 (for example, the distance between the pressing plate 107 and the inner surface of the first side of the housing 101 and the limiting structure 1062 is smaller than the radial section of the second side of the insulating fixing foot 103 E.g., a rectangular cross-section, which may be rectangular or square), and, with such an arrangement, when the insulating fixing foot 103 is in the stowed or deployed position, since the limiting structure 1062 is limited by the housing 101 and the pressing plate 107, when the external force is not applied, the rotating shaft 1061 can not rotate any more, thereby serving as a limiting function, optionally, the portion of the pressure plate 107 opposite to the limiting structure 1062 is an elastic structure, such as a cantilever structure, or a structure made of a material having elasticity, etc., by which, when the insulating fixing foot 103 is subjected to an external force, the limiting structure 1062 can exert a pressure on the elastic structure under the action of an external force, so that the elastic structure is deformed, and then the deformation is to allow the limiting structure 1062 to rotate, so as to allow the rotating shaft 1061 to drive the insulating fixing foot 103 to rotate, thereby realizing the switching between the retracted position and the extended position of the insulating fixing foot 103.

Alternatively, the pressure plate 107 may be fixed in the housing 101 by any suitable means, such as screwing, bonding, welding, etc., and in the embodiment of the present application, the pressure plate 107 is fixed by a screw 108 connected to a threaded seat provided in the housing 101. The assembly of the insulating fixing feet can be facilitated by screwing, for example, the insulating fixing feet can penetrate into the first side of the casing 101 from the inside of the casing 101, and the insulating fixing feet are fixed by the pressing plate 107 and the screw 108. It is worth mentioning that for the convenience of assembly, the first side of the casing 101, i.e. the portion for mounting the insulating fixing feet 103 and the pins 105, may be a first cover, which may be further combined with a second cover to form the complete casing 101.

With the first example structure, the insulating fixing foot 103 may be installed outward from the housing, which may be referred to as an internal-loading plug assembly.

In a second example, as shown in fig. 7, the rotating shaft 109 is disposed on two opposite side walls of the first end of the insulating fixing leg 103 and protrudes to two sides of the insulating fixing leg 103, an opening 111 is disposed on a side wall of the receiving groove 104, and the rotating shaft 109 is rotatably disposed in the opening 111. The shape of the rotating shaft 109 may be cylindrical, and optionally, the axial direction of the rotating shaft 109 is substantially perpendicular to the length extending direction of the insulating fixing foot 103.

In this example, as shown in fig. 7, the insulating fixing foot 103 may be installed from the outside of the housing, that is, externally installed, and optionally, for convenience of installation, grooves 112 are further provided on two side walls at the opening of the receiving groove 104.

Optionally, the bottom of the receiving groove 104 is provided with a cantilever 110, when the insulating fixing foot 103 is in the unfolding position, the first end of the insulating fixing foot 103 abuts against the cantilever 110, so that the insulating fixing foot in the unfolding position is limited to rotate by the cantilever 110 to ensure that the insulating fixing foot is stably in the unfolding position, thereby facilitating the insertion of the insulating fixing foot into the jack. Alternatively, the included angle between the extended position and the retracted position is substantially 90 degrees, when the insulating fixing foot 103 rotates from the retracted position to the extended position, the side wall of the first end portion thereof abuts against the side wall of the receiving groove 104 adjacent to the first end portion of the insulating fixing foot 103, so as to limit the insulating fixing foot 103 to continue rotating in the direction larger than 90 degrees, while the first end portion of the insulating fixing foot 103 is substantially in the shape of a square block, two corners of the square block close to the cantilever 110 can be set to arc-shaped corners, and the end surface of the first end portion of the insulating fixing foot 103 abuts against the cantilever 110, as shown in fig. 8, so that the two are interfered with each other to generate an acting force to limit the insulating fixing foot 103 to be stable in the extended position, thereby preventing the insulating fixing foot 103 from rotating when being inserted into the insertion hole.

Optionally, as shown in fig. 5, when the insulating fixing foot 103 is in the retracted position, at least a part of the insulating fixing foot 103 is tightly fitted and fixed in the accommodating groove 104, as shown in fig. 9, so that the insulating fixing foot 103 is stably in the retracted position to prevent it from falling out of the accommodating groove 104, optionally, a protrusion is provided on a side wall of the first end portion of the insulating fixing foot 103, or a protrusion is provided on a side wall of the accommodating groove 104, and when the insulating fixing foot 103 is in the retracted position, the insulating fixing foot 103 is tightly fitted and fixed in the accommodating groove 104 by the protrusion (i.e., interference between the protrusion and the side wall of the accommodating groove at a position indicated by an arrow in fig. 9). Alternatively, the sidewall of the receiving groove 104 may be provided as a resilient structure, such as the cantilever 110 or made of a material having elasticity.

With the above arrangement, when the insulating fixing foot 103 is acted by an external force applied by a user, the external force applies a pressure to the cantilever 110 and the sidewall of the accommodating groove 104, so as to deform, and further deform to allow the insulating fixing foot 103 to rotate, so as to switch the insulating fixing foot 103 between the retracted position and the extended position (as shown in fig. 6).

In a third example, as shown in fig. 10, the first end 211 of the insulating fixing foot 103 is detachably connected to the housing, and the second end of the insulating fixing foot 103 is located outside the housing. Optionally, a first slot 210 is disposed on a first side of the housing, and the insulating fixing foot 103 is configured to: the first end 211 of the insulating fixing pin 103 is rotatably disposed in the first slot 210 as a rotation axis, wherein the first slot 210 is configured as: the first end 211 rotated to the first position is allowed to move into the first card slot 210 or move out of the first card slot 210, and the first end 211 rotated to the second position is restricted from being located in the first card slot 210 and not separated from the housing.

Optionally, a first dimension (a dimension d1 shown in fig. 12) of the opening of the first card slot 210 in the first side of the housing in the first direction is larger than a second dimension (a dimension d2 shown in fig. 12) in the second direction, wherein, as shown in fig. 11, two side walls of the insulating fixing foot 103 opposite to the first end 211 are respectively provided with a protruding structure 212, and a distance between outer side surfaces of the protruding structures 212 is smaller than or equal to the first dimension and larger than the second dimension, wherein the first direction and the second direction are parallel to the surface of the first side of the housing. Optionally, the depth of the first slot 210 may be set to at least accommodate the first end 211 of the insulating fixing pin, the first end 211 of the insulating fixing pin may serve as a rotation shaft, and optionally, the radial dimension of the first end 211 of the insulating fixing pin is smaller than the radial dimension of the main body portion of the insulating fixing pin connected to the first end 211, so that a groove is formed between the protrusion 212 and the end surface of the main body portion adjacent to the first end 211, and the dimension of the groove in the axial direction of the insulating fixing pin may be matched to the thickness of the housing portion on both sides of the opening of the first slot 210.

Optionally, a support plate 2101 is disposed at the bottom of the first slot 210, and when the insulating fixing pin 103 is located in the first slot 210, the support plate 2101 supports the insulating fixing pin 103 to prevent the insulating fixing pin 103 from falling into the housing.
