The embodiment of the present invention provides a foldable plug, the structure of which is shown in fig. 1-6, comprising a base 100, a plug 200 and a limit structure 300. The base 100 includes a housing 110 and a supporting base 120 fixed in the housing 110, the housing 110 has a first sidewall, and the first sidewall has an opening 111.

It should be understood that the openings 111 need to penetrate through the first sidewall, and the number of the openings 111 is the same as that of the pins 200. The size of the opening 111 is determined according to the size of the latch 200, and generally, the length of the opening 111 is slightly larger than the length of the latch 200, and the width of the opening 111 is slightly larger than the thickness of the latch 200.

It should be noted that, in order to facilitate the installation of the latch 200 and the limiting structure 300 in the housing 110, the latch 200 includes an upper housing and a lower housing, and the upper housing and the lower housing are fixed together by a bolt to form the housing 110 having an inner cavity.

The latch 200 is rotatably coupled to the support base 120 with a rotational axis of the latch 200 parallel to the first sidewall, the latch 200 being rotatable about the rotational axis relative to the housing 110 between a first position and a second position. When the latch 200 is in the first position, the latch 200 is located within the housing 110; when the latch 200 is located at the second position, the latch 200 extends out of the housing 110 through the opening 111, and the length direction of the latch 200 is perpendicular to the first sidewall.

It should be understood that the number of pins 200 in the plug may be selected as desired, and that the pins correspond to the openings one to one. For example, the number of the pins 200 may be one, two, or three. When the number of the pins 200 is two, the two pins 200 are disposed opposite to each other, and the rotation axes 122 of the two pins 200 should coincide.

The limiting structure 300 is disposed between the housing 110 and the latch 200, and after the limiting structure 300 is used to prevent the latch 200 from rotating to the second position, the latch 200 continues to rotate in the rotating direction from the first position to the second position, so that the latch 200 and the first sidewall of the housing 110 are kept in a vertical state.

It should be noted that the limiting structure 300 may be selected according to actual situations, as long as the bolt 200 can be prevented from rotating continuously in the rotation direction from the first position to the second position when the bolt 200 is located at the second position. For example, the above-mentioned stopper structure 300 may be a protrusion located on the outer surface of the first sidewall of the housing 110. When the latch 200 is rotated in a direction from the first position to the second position, the latch 200 is rotated in a direction to approach the protrusion. When the latch 200 is rotated to the second position, the protrusion abuts against the latch 200, so that the latch 200 is prevented from rotating along the rotation direction from the first position to the second position.

When the socket is not used, the plug 200 is located at the first position, and at this time, the plug 200 is located in the housing 110, so that the volume of the plug can be reduced. When the socket is used, the plug pin 200 is rotated in a direction close to the second position, and the limiting structure 300 prevents the plug pin 200 from rotating continuously in the direction from the first position to the second position, so that the plug pin 200 can rotate to the second position. At this time, the latch 200 is perpendicular to the first sidewall of the housing 110, so that the latch 200 can be conveniently inserted into or pulled out of the insertion hole of the socket.

Known by the structure of above-mentioned foldable plug and the working process of foldable plug, the utility model provides an in the foldable plug, be equipped with limit structure 300 between bolt 200 and casing 110 to limit structure 300 can prevent bolt 200 to continue to rotate in the direction of rotation of first position to second position after bolt 200 rotates to the second position, thereby makes limit structure 300 can restrict bolt 200 and keep at the second position. At this time, the plug 200 can be in a state of being perpendicular to the first sidewall of the housing 110 under the action of the limiting structure 300, so that the plug 200 of the folding plug can be conveniently inserted into or pulled out of the through hole of the socket. At this moment, when the user inserts the bolt 200 of plug or extracts the through-hole of socket, easy operation for the user has good plug experience when using foldable plug.

As a possible implementation manner, referring to fig. 2 and 3, the support seat 120 includes a support seat body 121 and a rotating shaft 122; the supporting seat body 121 is provided with a shaft hole, the rotating shaft 122 penetrates through the shaft hole and is sleeved on the supporting seat body 121, and the rotating shaft 122 is parallel to the first side wall of the shell 110; the latch 200 is fixed to the shaft 122.

In this case, the rotation axis of the plug 200 is the axis line of the rotation shaft 122. The rotating shaft 122 passes through the shaft hole and is sleeved on the support body, so that the rotating shaft 122 can rotate around the axis of the rotating shaft 122 relative to the housing 110, and the bolt 200 can be driven to rotate between the first position and the second position.

For example, when the number of the latches 200 is two, the two latches 200 may be fixed to two different rotating shafts 122, or may be fixed to the same rotating shaft 122. When the two bolts 200 are fixed on two different rotating shafts 122, the axes of the two rotating shafts 122 should coincide. When the two rotating shafts 122 are fixed on the same rotating shaft 122, the two latches 200 can rotate synchronously, so that the rotation of the latches 200 can be controlled conveniently.

Specifically, when the two pins 200 are fixed on the same rotating shaft 122, the rotating shaft 122 should be made of an insulating material, so as to avoid a short circuit between the two pins 200.

For example, referring to fig. 6, the position-limiting structure 300 includes a first position-limiting portion 310 protruding from a sidewall of the rotating shaft 122 and a second position-limiting portion 320 disposed on an inner surface of the first sidewall. It should be understood that the second position-limiting portion 320 may protrude from the inner surface of the first sidewall of the housing 110, or may be flush with the inner surface of the first sidewall.

When the plug pin 200 rotates from the first position to the second position, the first position-limiting portion 310 is driven by the rotating shaft 122 to rotate in a direction close to the second position-limiting portion 320, and when the plug pin 200 rotates to the second position, the first position-limiting portion 310 contacts with the second position-limiting portion 320.

At this time, when the plug pin 200 rotates to the second position, the first limiting portion 310 contacts with the second limiting portion 320, so that the rotating shaft 122 can be limited, the rotating shaft 122 is prevented from rotating continuously along the direction from the first position to the second position, the plug pin 200 can be limited, and the plug pin 200 is prevented from rotating continuously in the rotating direction from the first position to the second position under the driving of the rotating shaft 122.

Moreover, the limiting device is arranged in the casing 110, and the size of the bolt 200 can be reduced, so that the bolt 200 can be conveniently stored and transported.

Specifically, the first position-limiting portion 310 has a first position-limiting surface, and the second position-limiting portion 320 has a second position-limiting surface, and when the plug pin 200 moves to the second position, the first position-limiting surface and the second position-limiting surface are attached to each other. At this time, the first and second position-limiting parts 310 and 320 have a larger contact area, so that the position-limiting stability of the position-limiting structure 300 can be improved, and the plug pin in the folding plug has a longer rotation life.

Meanwhile, the shapes of the first position-limiting portion 310 and the second position-limiting portion 320 can be selected according to actual situations, as long as the first position-limiting portion 310 has a first position-limiting surface and the second position-limiting portion 320 has a second position-limiting surface. For example, the first stopper portion 310 and the second stopper portion 320 are each rectangular parallelepiped. And the thickness of the first limiting part 310 is 1.2 mm-2.0 mm, so that the first limiting part 310 has better strength, and the rotating life of the plug pin 200 in the folding plug can be prolonged. At this time, after the bolt 200 is rotated for a plurality of times, the first position-limiting portion 310 and the second position-limiting portion 320 are matched to limit the bolt 200.

When the plug 200 of the foldable plug is subjected to the rotation test, it is found that after the plug 200 is subjected to the rotation test for 20000 times, the first limiting portion 310 and the second limiting portion 320 can still limit the plug 200, so that the plug 200 cannot continue to rotate in the direction from the first position to the second position after rotating to the second position.

For example, referring to fig. 2, the support seat body 121 is formed by splitting a first portion 121A and a second portion 121B along a plane where an axis of the axial hole is located, the first portion 121A is fixed on an inner wall of the housing 110, and the first portion 121A and the second portion 121B are connected to each other. The first half hole is arranged at the position, corresponding to the shaft hole, of the first part 121A, the second half hole is arranged at the position, corresponding to the shaft hole, of the second part 121B, and the shaft hole is formed by splicing the first half hole and the second half hole. At this time, when assembling the foldable plug, the rotating shaft 122 may be first disposed on the first half hole of the first portion 121A, and then the first portion 121A and the second portion 121B are connected, so that the rotating shaft 122 is located in the shaft hole formed by splicing the first half hole and the second half hole. Compared with the method that the rotating shaft 122 is directly inserted into the shaft hole on the supporting seat body 121, the rotating shaft 122 in the example is simple to install and convenient to operate.

In addition, in order to prevent the rotation shaft 122 from moving in the axial direction relative to the housing 110, a baffle may be disposed on an inner wall of the housing 110, the baffle being disposed at an end of the rotation shaft 122 and perpendicular to the rotation shaft 122.

Of course, the first part 121A and the second part 121B are detachably connected to facilitate later replacement of the folding plug for servicing. For example: the first portion 121A and the second portion 121B are engaged with each other.

Specifically, referring to fig. 2 and 3, in order to ensure the stability of the rotating shaft 122 during rotation, the supporting seat body 121 includes a plurality of supporting plates which are parallel to each other and are disposed opposite to each other. Each supporting plate is provided with a shaft hole. The shaft 122 is disposed between the plurality of shaft holes. The plurality of shaft holes can limit the rotating shaft 122, limit the rotating shaft 122 to move relative to the supporting plate, and simultaneously allow the rotating shaft 122 to rotate relative to the supporting plate, so that the stability of the rotating shaft 122 during rotation can be ensured.

For example, the plug has two pins, the first side wall has two openings, the two pins correspond to the two openings one by one, and the two pins are located on the same rotating shaft. The supporting seat body 121 includes four supporting plates axially arranged along the rotating shaft 122, the four supporting plates are parallel to each other and are disposed oppositely, and the four supporting plates are fixedly connected to the inner surface of the first side wall of the housing 110. At this moment, all be equipped with the shaft hole in four backup pads, the pivot is located between four shaft holes. At the moment, the four shaft holes are matched to limit the rotating shaft, so that the stability of the rotating shaft during rotation can be improved.

Meanwhile, in order to ensure that both the pins can extend out of the housing through the corresponding openings 111, one opening 111 is located between the first support plate and the second support plate axially arranged along the rotating shaft 122, and the other opening 111 is located between the third support plate and the fourth support plate axially arranged along the rotating shaft 122.

Moreover, the second limiting portion 320 is located between the second support plate and the third support plate which are axially arranged along the rotating shaft 122, so that the second limiting portion 320 can limit the rotating shaft by matching the first limiting portion 310.

When the support seat body 121 is split along the plane where the axis of the axial hole is located to form the first portion 121A and the second portion 121B, the second portions 121B of the plurality of support plates are fixedly connected to each other to form a gland in order to facilitate the connection between the second portions 121B of the plurality of support plates and the first portion 121A. At this time, the second portions 121B of the plurality of support plates may be simultaneously connected to the first portion 121A by only connecting the second portion 121B of one support plate to the first portion 121A.

As a possible implementation manner, referring to fig. 1 to 3, the base 100 further includes a receiving shell 130 fixed in the housing 110, the receiving shell 130 encloses a receiving cavity, and the receiving cavity is communicated with the opening 111. When the latch 200 rotates from the first position to the second position, the latch 200 is received in the receiving cavity through the opening 111. In this case, the housing 130 can limit the latch 200, and prevent the latch 200 from rotating deeply into the housing 110 and being unable to manually rotate the latch 200 out of the housing 110 from the first position.

As an embodiment, referring to fig. 1, 4 and 5, the folding plug further includes a conductive elastic sheet 400, where the conductive elastic sheet 400 includes a fixing portion and an elastic arm, the elastic arm has a first interference portion, and the fixing portion is fixed in the housing 110. When the plug 200 is located at the second position, the first abutting portion of the elastic arm abuts against the plug 200.

At this time, the cable of the folding plug may be connected to the fixing portion of the conductive elastic piece 400. When the plug 200 is located at the second position, the first abutting portion of the elastic arm is connected to the plug 200, so that when the plug 200 is engaged with the socket, current can be supplied to the electrical appliance after passing through the plug 200, the conductive elastic piece 400 and the cable in sequence.

Moreover, the cable is connected with the fixing portion of the conductive elastic sheet 400, the connection portion of the conductive elastic sheet 400 and the cable does not move along with the rotation of the plug 200, and compared with the case that the cable is directly connected with the plug 200, the connection between the conductive elastic sheet 400 and the cable is stable, so that the service life of the folding plug can be prolonged.

Illustratively, referring to fig. 2 and 4-6, the latch 200 is partially embedded in the shaft 122, and first and second ends of the latch 200 are exposed outside the shaft 122, the first and second ends being disposed opposite to each other. Referring to fig. 5, when the latch 200 is located at the second position, the second end portion extends out of the housing from the opening, and the first end portion abuts against the first abutting portion. It should be noted that the plug 200 may be combined with the rotating shaft 122 by using an injection molding process, so that the plug 200 is vertically fixed to the rotating shaft 122 and the first end and the second end of the plug 200 are exposed out of the rotating shaft 122.

Meanwhile, the first end portion is arc-shaped, the first abutting portion is arc-shaped, and when the plug pin 200 is located at the second position, the first abutting portion is attached to the first end portion.

In this case, the first abutting portion and the first end portion are both arc-shaped, so that the first abutting portion and the first end have a larger contact area, and thus, when the plug pin 200 is located at the second position, the resistance between the first end portion and the first abutting portion can be reduced.

In addition, referring to fig. 2, the fixing portion of the conductive elastic piece 400 is pressed between the pressing cover and the receiving shell 130, so that the fixing portion of the conductive elastic piece 400 is fixed relative to the housing 110, and the elastic arm of the conductive elastic piece 400 is located between the plug 200 and the pressing cover.

At this moment, when the plug 200 is located the second position, the first end of the plug 200 abuts against the first abutting portion of the elastic arm, and the elastic portion elastically deforms relative to the fixing portion, so that the first abutting portion can apply an acting force towards the first side wall to the first end, and therefore the first abutting portion and the first end are combined more tightly, and resistance between the first abutting portion and the first end is further reduced. Meanwhile, the acting force applied to the first end by the first abutting portion can limit the latch 200, so that the latch 200 is kept in a state of being perpendicular to the first side wall.

Specifically, referring to fig. 4, the elastic arm further has a second abutting portion, when the latch 200 is located at the first position, the second abutting portion abuts against the first end portion, and the second abutting portion applies a force to the first end portion toward the first sidewall.

In this case, since the first end and the second end are disposed opposite to the rotating shaft 122, and the second abutting portion applies an acting force toward the first sidewall to the first end, the first end can limit the latch 200, and the second end of the latch 200 is prevented from rotating toward the second position, so that the latch 200 is maintained in the state of the first position.

It should be noted that, when the second abutting portion of the elastic arm is disposed along the tangential direction of the first abutting portion, the first end portion of the plug 200 can be moved between the first abutting portion and the second abutting portion conveniently.

As a possible implementation, referring to fig. 2, 4 and 5, the folding plug includes a regulating module 500 fixed in the housing 110, the regulator module is electrically connected with the plug 200, and the regulating module 500 can regulate the current and voltage of the power supply.

In this case, the adjusting module 500 can adjust the current and voltage of the power source so that the voltage and current magnitude of the power source delivered from the plug to the appliance conform to the rating of the appliance, so that the plug can be applied to different kinds of appliances.

It should be noted that the adjusting module 500 may be a circuit board, and the circuit board is provided with input contact points and output contact points, and the number of the input contact points may be designed according to the number of the latches 200, as long as the number of the input contact points corresponds to the number of the output contact points one to one. At this time, the fixing portions of the conductive elastic sheet 400 are electrically connected to the input contacts one by one, and the output contacts are connected to the cable of the folding plug, so that the current and voltage of the power supply can be adjusted.

Of course, the circuit board may be fixedly connected to the housing 110, or may be detachably disposed in the housing 110. Replacement and maintenance of the circuit board can be facilitated when the circuit board is detachably provided in the housing 110.
