Description

Technical Field

[0002] As a common electrical accessory product, sockets are used frequently in daily life, and are used by people of all ages. With the continuous development of technology, the performance of wall sockets tends to be stable, the service life is longer, and the application range is wider. After installation, they are generally not easily adjusted or replaced. Although the usage method is monotonous, there are still certain differences in the feel of different people. The state stipulates the plug-in and pull-out force range of sockets. The plug-in and pull-out force of existing sockets on sale must meet national standards, but the plug-in and pull-out force is often a fixed value, and users cannot adjust it independently. Excessive plug-in and pull-out force will make it difficult for the elderly, weak and young girls to use, and too small plug-in and pull-out force will give people an unreliable feel of use, which is not enough to support some heavier charging cables, and there are safety hazards when they fall off during use. In addition, different brands of sockets have different plug-in and pull-out feel and different plug-in and pull-out forces, resulting in different user habits. In addition, with the increase of years of use, the plug-in and pull-out force will become looser or tighter due to loosening of the socket or carbon accumulation of the socket. The socket will not be easily replaced after installation. The above inconvenience is a common problem of today's sockets. Summary of the invention

DETAILED DESCRIPTION

[0046] The following embodiments are given in conjunction with the accompanying drawings to further illustrate the specific implementation of the socket with adjustable plugging and extraction force of the utility model. The socket with adjustable plugging and extraction force of the utility model is not limited to the description of the following embodiments.

[0047] like Figure 1-2 As shown, the socket with adjustable plugging and extraction force of this embodiment includes a shell and a socket assembly 1, a pressure plate 21, a terminal 22, a protective door 23 and an adjustment device respectively arranged in the shell, the pressure plate 21 is used to limit the socket assembly 1, the terminal 22 is used to fix the power cord, the socket assembly 1 is provided with a socket structure for fixing the plug, the socket structure is connected to the power cord through the terminal 22, and the protective door 23 is used to shield the socket structure. The protective door 23 of this embodiment will only be removed and the socket structure will be exposed when the forces on both sides are balanced, and foreign objects on one side will be blocked by the protective door 23 to prevent accidental electric shock; of course, as a socket of other embodiments, the protective door 23 may not be provided, or the protective door 23 may also push the protective door 23 to expose the socket structure when foreign objects are inserted on one side, which all belong to the protection scope of the utility model.

[0048] like Figure 3-6As shown, at least one group of the socket structures is included. Two groups of socket structures can constitute a group of two sockets for fixing a two-pin plug, and three groups of socket structures can constitute a group of three sockets for fixing a three-pin plug. The socket structures all include two spring pieces 3 arranged opposite to each other. A slot for fixing the plug is formed between the two spring pieces 3 of each group of socket structures. The adjustment device includes an adjustment mechanism 4 and a driving mechanism 5. The driving mechanism 5 is driven by the adjustment mechanism 4 to push and move away from the spring pieces 3 of the socket structure, respectively. When the driving mechanism 5 pushes the spring pieces 3 of the corresponding socket structure, the two spring pieces 3 of the socket structure are pushed toward each other by the corresponding driving mechanism 5; when the driving mechanism 5 moves away from the spring pieces 3 of the corresponding socket structure, the two spring pieces 3 of the socket structure are moved away from each other by its own elastic drive.

[0049] In the socket with adjustable plugging and extraction force of this embodiment, the driving mechanism 5 is driven by the adjusting mechanism 4 to push and move away from the spring sheet 3, so as to control the distance between the two spring sheets 3, and further control the clamping force of the spring sheets 3. Not only can it be adjusted to a suitable clamping force according to different types of plugs, but also after the spring sheets 3 are aged, it can be used to increase the clamping force of the spring sheets 3, which can effectively improve the user experience.

[0050] like Figure 6-7 As shown, the clamping force F of the plug structure on the plug is related to the material used, wall thickness t, deformation arm length L, arm width H, etc. The material characteristics are qualitative factors. The clamping force F is proportional to the design factors wall thickness t, arm width H, deformation ΔX, and inversely proportional to the deformation arm length L. The clamping force F generated by the plug itself is a constant value, which is determined by the above qualitative factors and structural design factors. Therefore, adding the force of the driving mechanism 5 outside the arm 3 of the plug can increase the clamping force, thereby changing the plug-in force.

[0051] like Figure 4 As shown, this embodiment is provided with three groups of the socket components 1 and three groups of the wiring terminals 22, the three groups of socket components 1 are respectively the first socket component 11, the second socket component 12 and the third socket component 13, the three groups of wiring terminals 22 are respectively the first wiring terminal, the second wiring terminal and the third wiring terminal, the first socket component 11, the second socket component 12 and the third socket component 13 are respectively connected to the first wiring terminal, the second wiring terminal and the third wiring terminal, the first wiring terminal is used to connect one of the live wire and the neutral wire, the second wiring terminal is used to connect the other of the live wire and the neutral wire, and the third wiring terminal is used to connect the ground wire;

[0052] The first socket assembly 11 is provided with a first conductive sheet 111 connected to the first terminal, and a first two-pin socket 112 and a first three-pin socket 113 as socket structures, respectively, and the first two-pin socket 112 and the first three-pin socket 113 are respectively connected to the first conductive sheet 111;

[0053] The second socket assembly 12 is provided with a second conductive sheet 121 connected to the second terminal, and a second two-plug socket 122 and a second three-plug socket 123 as socket structures, respectively, and the second two-plug socket 122 and the second three-plug socket 123 are respectively connected to the second conductive sheet 121;

[0054] The third socket assembly 13 is provided with a third three-pin socket as a socket structure, and the third three-pin socket is connected to the third wiring terminal;

[0055] The first two-pin socket 112 and the second two-pin socket 122 constitute a two-pin socket for fixing a two-pin plug, and the first three-pin socket 113, the second three-pin socket 123 and the third three-pin socket constitute a three-pin socket for fixing a three-pin plug. In this embodiment, a two-pin socket and a three-pin socket are provided, which can be used to fix a two-pin plug and a three-pin plug, or only one of the two-pin socket and the three-pin socket can be provided, or the number of the three-pin socket and / or the three-pin socket can be increased, which all belong to the protection scope of the present utility model.

[0056] like Figure 5-6 As shown, the two elastic pieces 3 of the plug-in structure are respectively a static elastic piece 31 and a dynamic elastic piece 32 , a positioning structure for limiting the static elastic piece 31 is provided in the shell, and the driving mechanism 5 is used to push and move away from the dynamic elastic piece 32 so that the dynamic elastic piece 32 approaches and moves away from the static elastic piece 31 .

[0057] Further, the movable elastic piece 32 includes a contact piece 321 and a bent piece 322 connected between the contact piece 321 and the static elastic piece 31, the slot is formed between the bent piece 322, the static elastic piece 31 and the movable elastic piece 32, the connection between the bent piece 322 and the static elastic piece 31 is the rotation center of the contact piece 321, and the driving mechanism 5 is used to push the contact piece 321 to rotate around the rotation center, so that the angle between the contact piece 321 and the static elastic piece 31 increases. It can be understood that the rotation center of the contact piece 321 can also be adjusted to other positions on the movable elastic piece 32, all of which belong to the protection scope of the utility model.

[0058] like Figure 6 As shown, the static elastic piece 31 and the contact piece 321 are arranged at an oblique angle, and the end of the contact piece 321 away from the bending piece 322 is spaced from the static elastic piece 31, and the distance from the end of the contact piece 321 away from the bending piece 322 to the static elastic piece 31 is smaller than the distance from the end of the contact piece 321 close to the bending piece 322 to the static elastic piece 31. When the driving mechanism 5 pushes the contact piece 321, it drives the end of the contact piece 321 away from the bending piece 322 to approach the static elastic piece 31.

[0059] like Figure 3-4As shown, the socket of this embodiment includes at least two groups of the socket assemblies 1, and at least two groups of driving mechanisms 5 respectively arranged corresponding to the two groups of socket assemblies 1, the at least two groups of socket assemblies 1 are respectively a first socket assembly 11 and a second socket assembly 12, the static elastic pieces 31 of the socket structures of the first socket assembly 11 and the second socket assembly 12 are arranged relatively, the dynamic elastic pieces 32 of the socket structures of the first socket assembly 11 and the second socket assembly 12 are respectively arranged on the side where the static elastic pieces 31 are away from the other static elastic pieces 31, the positioning structure is arranged between the first socket assembly 11 and the second socket assembly 12, and is used to limit the static elastic pieces 31 of the socket structures of the first socket assembly 11 and the second socket assembly 12 respectively, and the two groups of driving mechanisms 5 are respectively provided with push rods, and the push rods of the two driving mechanisms 5 are relatively arranged on the outsides of the first socket assembly 11 and the second socket assembly 12, and are used to push the dynamic elastic pieces 32 of the socket structures of the first socket assembly 11 and the second socket assembly 12 to move inward respectively.

[0060] The positioning structure in this embodiment includes two first positioning plates 61 and two second positioning plates 62, the two first positioning plates 61 are respectively used to limit the static elastic pieces 31 of the first two plug sockets 112 and the second two plug sockets 122, the driving mechanism 5 is respectively used to push the dynamic elastic pieces 32 of the first two plug sockets 112 and the second two plug sockets 122, the two second positioning plates 62 are respectively used to limit the static elastic pieces 31 of the first three plug sockets 113 and the second three plug sockets 123, and the driving mechanism 5 is respectively used to push the dynamic elastic pieces 32 of the first three plug sockets 113 and the second three plug sockets 123.

[0061] Furthermore, the two first positioning plates 61 are in a T-shape, and the first positioning plates include two vertically connected positioning plates, wherein the side surface of one positioning plate is used to limit the static elastic sheet 31, and the other positioning plate is connected to the first partition plate 63;

[0062] A second partition plate 65 is disposed between the two second positioning plates 62. The two second positioning plates 62 are respectively connected to the second partition plates 65. The second positioning plate 62 is in a flat plate shape, and the end surface away from the second partition plate 65 is used to limit the static elastic piece 31.

[0063] It is understandable that the shapes of the first positioning plate 61 and the second positioning plate 62 can be interchangeable, or both can adopt the T-shape or flat plate shape. In addition, the first positioning plate 61 and the second positioning plate 62 can also adopt other shapes, such as a flat plate shape, but the side-limiting static elastic sheet 31, or a plurality of bosses arranged at intervals, and the plurality of bosses are respectively used to limit the static elastic sheet 31, all belong to the protection scope of the utility model.

[0064] like Figure 8-9As shown, the driving mechanism 5 of this embodiment includes a lever 51 rotatably mounted on the pressure plate 21, and a push rod 52 for pushing the spring sheet 32, and the adjusting mechanism 4 is used to push the lever 51 to rotate, so that the lever 51 drives the push rod 52 to push the spring sheet 32. The lever 51 can directly or indirectly drive the push rod 52, and the lever 51 and the push rod 52 can also be an integrated structure. It can be understood that, as other embodiments, the driving mechanism 5 can also be a first sliding block slidably mounted, and the adjusting mechanism 4 drives the first sliding block to slide to push the spring sheet 32. In addition, the driving mechanism 5 can also be rotatably mounted on the housing, all of which belong to the protection scope of the present utility model.

[0065] Furthermore, the driving mechanism 5 includes an elastic structure for providing an elastic clamping force for the spring sheet 3 and preventing damage to the driving mechanism 5. When the plug is inserted between the two spring sheets 3 of the plug-in structure, the plug acts on the spring sheet 3, and the spring sheet 3 causes the elastic structure of the driving mechanism 5 to store energy, thereby preventing damage to the driving mechanism 5 and increasing the clamping force of the spring sheet 32.

[0066] Further, the driving mechanism 5 also includes a connecting rod 53 connected between the lever 51 and the top rod 52. The lever 51 and the top rod 52 of the driving mechanism 5 are relatively arranged on the sides of the pressing plate 21. The lever 51 is located on the front of the pressing plate 21, and the top rod 52 is located on the back of the pressing plate 21. The connecting rod 53 is located on the side of the pressing plate 21 and connected between the lever 51 and the top rod 52. The lever 51 and the top rod 52 are relatively arranged on the sides of the pressing plate 21. The adjusting mechanism 4 can be arranged on the side of the pressing plate 21 away from the plug-in assembly 1, which not only prevents the adjusting mechanism 4 and the plug-in assembly 1 from interfering with each other when they are arranged on the same side, but also allows the adjusting mechanism 4 to be located on the side of the pressing plate 21 facing the outside of the wall, which is convenient for operating and controlling the adjusting mechanism 4. Preferably, the driving mechanism 5 is integrally injection molded, the lever 51 and the top rod 52 are in the shape of a flat plate, and the connecting rod 53 is in the shape of a cylinder.

[0067] It is understandable that the driving mechanism 5 can also be arranged on the same side as the plug-in assembly 1, and a avoidance structure is arranged on the pressure plate 21, so that the adjustment mechanism 4 can drive the driving mechanism 5 to move through the pressure plate 21 from the avoidance structure, or the adjustment mechanism 4, the driving mechanism 5 and the plug-in assembly 1 are arranged on the same side of the pressure plate 21, and the adjustment mechanism 4 is operated and controlled by a tool such as a screwdriver through the avoidance structure through the pressure plate 21. All of these belong to the protection scope of the present utility model. In addition, by relatively arranging the lever 51 and the push rod 52 of the driving mechanism 5 on the sides of the pressure plate 21, the length of the driving mechanism 5 can be increased, thereby increasing the elasticity of the driving mechanism 5. When the plug is inserted into the plug-in structure, the spring sheet 3 pushes the driving mechanism 5 under the push of the plug, so that the driving mechanism 5 produces elastic deformation, avoids damage to the driving mechanism 5, and allows the plug to be inserted smoothly. The elastic restoring force of the driving mechanism 5 can also be used to push the spring sheet 32 ​​to clamp the plug. That is, the elastically deformable structure formed by the lever 51 in this embodiment serves as the elastic structure of the driving mechanism 5, and there is no need to set a separate elastic member. Of course, as other embodiments, elastic parts such as compression springs, torsion springs, and spring sheets can also be set as elastic structures. For example, the elastic part acts on the spring sheet 3 through the lever 51 or the top rod 52, and the elastic part can provide an elastic clamping force for the spring sheet 3. When the plug is inserted between the two spring sheets 3 of the socket structure, the plug will act on the spring sheet 3, and the expansion of the spring sheet 3 can cause the elastic part to deform and store energy through the lever 51 or the top rod 52.

[0068] Further, the push rod 52 includes a first push rod 521 and a second push rod 522 arranged at an oblique angle, the first push rod 521 is connected between the second push rod 522 and the connecting rod 53, and the second push rod 522 is provided with a contact boss 523, the cross section of the contact boss 523 is triangular, and the contact boss 523 is provided with a flat contact surface, the contact surface is used to push the spring sheet 32, and the contact boss 523 pushes the spring sheet 32 ​​through the contact surface to increase the contact area and provide a more reliable pushing and supporting effect. In addition, the first push rod 521 and the second push rod 522 are arranged at an oblique angle, which can not only increase the length of the push rod 52 and further increase the elasticity of the push rod 52, but also the angle of the reaction force when the push rod 52 pushes the spring sheet 32 ​​is closer to the axis of the second push rod 522.

[0069] Furthermore, the driving mechanism 5 includes two push rods 52, which are respectively connected to the lever 51 through a connecting rod 53 and are relatively arranged on both sides of the rotation center of the lever 51. The two push rods 52 of the driving mechanism 5 are respectively used to push two different socket assemblies 1.

[0070] In this embodiment, the two driving mechanisms 5 are respectively a first driving mechanism 501 and a second driving mechanism 502. The two push rods 52 of the first driving mechanism 501 are respectively used to push the first two plug sockets 112 of the first plug socket assembly 11 and the second three plug sockets 123 of the second plug socket assembly 12. The two push rods 52 of the second driving mechanism 502 are respectively used to push the first three plug sockets 113 of the first plug socket assembly 11 and the second two plug sockets 122 of the second plug socket assembly 12.

[0071] Furthermore, the rotation centers of the levers 51 of the two driving mechanisms 5 are arranged to overlap, and when the levers 51 of the two driving mechanisms 5 rotate in opposite directions respectively, the two driving mechanisms 5 simultaneously drive their two push rods 52 to push and move away from the corresponding spring pieces 3 respectively.

[0072] In this embodiment, the two push rods 52 of the first driving mechanism 501 of the driving mechanism are respectively arranged on one side of the connected lever 51 in the clockwise direction. When the lever 51 of the first driving mechanism 501 of the driving mechanism rotates in the clockwise direction, the two push rods 52 are driven to push the spring pieces 3 of the first and second plug sockets 112 of the first plug socket assembly 11 and the second and third plug sockets 123 of the second plug socket assembly 12 respectively. When the lever 51 of the first driving mechanism 501 of the driving mechanism rotates in the counterclockwise direction, the two push rods 52 are driven to move away from the spring pieces 3 of the first and second plug sockets 112 of the first plug socket assembly 11 and the second and third plug sockets 123 of the second plug socket assembly 12 respectively.

[0073] The two push rods 52 of the second driving mechanism 502 of the driving mechanism are respectively arranged on the counterclockwise side of the connected lever 51. When the lever 51 of the second driving mechanism 502 of the driving mechanism rotates in the counterclockwise direction, the two push rods 52 are driven to push the spring pieces 3 of the first three-plug socket 113 of the first socket assembly 11 and the second two-plug socket 122 of the second socket assembly 12 respectively. When the lever 51 of the second driving mechanism 502 of the driving mechanism rotates in the clockwise direction, the two push rods 52 are driven to move away from the spring pieces 3 of the first three-plug socket 113 of the first socket assembly 11 and the second two-plug socket 122 of the second socket assembly 12 respectively.

[0074] like Figure 3 As shown, the levers 51 of the two driving mechanisms 5 are arranged in an X-shape, and V-shaped operating spaces are formed between the two ends of the levers 51 of the two driving mechanisms 5, and the top angles of the two operating spaces are arranged opposite to each other.

[0075] like Figure 3 , 8As shown, the adjustment mechanism 4 includes a slider 42 provided with a toothed belt 41 and a worm 43 for driving the toothed belt 41 to move. The slider 42 is arranged in an operating space between the levers 51 of the two driving mechanisms 5. The worm 43 is used to drive the slider 42 to move between the opening and the top angle of the operating space. When the slider 42 moves toward the top angle of the operating space, the slider 42 is used to push the levers 51 of the two driving mechanisms 5 respectively, so that the angle α between the levers 51 of the two driving mechanisms 5 increases, so that the push rod 52 is close to the push spring 3.

[0076] The worm 43 drives the slider 42 to move, which not only ensures reliable cooperation, but also has a self-locking effect when the worm 43 and the toothed belt 41 are meshed, and there is no need to separately set the structure of the limit worm 43 and the toothed belt 41. Of course, the slider 42 can also be moved without using the worm 43, for example, the slider 42 can be directly moved by toggling it, and the structure of the limit slider 42 can be separately set, which can be a plurality of limit slots, and the plurality of limit slots correspond to a plurality of gears, so that the limit protrusion on the slider 42 moves between the plurality of limit slots, which all belong to the protection scope of the present utility model.

[0077] Furthermore, the adjustment mechanism 4 also includes a spring 44 connected between the two driving mechanisms 5, and the spring 44 is used to pull the two driving mechanisms 5 respectively, especially when the slider 42 moves toward the opening of the operating space, the spring 44 reduces the angle α between the levers 51 of the two driving mechanisms 5, so that the top rod 52 is away from the spring 3. When the driving mechanism 5 is not in contact with the spring 3, the driving mechanism 5 does not increase the additional clamping force, and the clamping force provided by the elasticity of the spring 3 itself can be designed according to the minimum national standard. Preferably, the two ends of the spring 44 are respectively hung on the upper limit of the connecting rod 53 of the two driving mechanisms 5.

[0078] This embodiment can control the actions of two driving mechanisms 5 at the same time through a slider 42 and a spring 44, and has the characteristics of a small number of parts and low cost. Of course, a slider 42 and a spring 44 can be separately provided for each driving mechanism 5 to adjust the insertion and extraction force of different spring pieces 3. In addition, the spring 44 can also be omitted, and the slider 42 can be provided with a hook or a similar structure to drive the angle α of the levers 51 of the two driving mechanisms 5 to decrease, which all belong to the protection scope of the utility model.

[0079] Furthermore, the adjustment mechanism 4 further includes a roller 47, which is transmission-connected to the worm 43 for driving the worm 43 to rotate, and the roller 47 extends outside the housing of the socket for operation.

[0080] Furthermore, the lever 51 includes a circular rotating portion 510, and a first rod portion 511 and a second rod portion 512 respectively connected to the rotating portion 510. A fixed shaft 513 is provided on the pressure plate 21. A rotating hole 514 for being sleeved on the fixed shaft 513 is provided in the center of the rotating portion 510, so that the lever 51 is rotatably installed on the pressure plate 21. The center line of the first rod portion 511 and the center line of the second rod portion 512 are arranged in parallel and relatively on both sides of the axis of the rotating hole 514. In this way, the angle α between the two levers 51 can be larger, thereby making the operating space larger, and being able to leave a larger operating space for the slider 42, so that the slider 42 can move to the top angle of the operating space.

[0081] like Figure 10-11 As shown, the slider 42 is cylindrical, and the side of the slider 42 is provided with a push surface in a curved shape, which is used to push the levers 51 of the two driving mechanisms 5 respectively, and is tangentially matched with the levers 51 when pushing. The top and bottom surfaces of the slider 42 are respectively provided with a toothed belt 41 and a guide block 45. The slider 42 is slidably arranged on the pressure plate 21, and a guide groove 46 for inserting the guide block 45 is provided on the pressure plate 21. The guide block 45 is inserted into the guide groove 46 for sliding cooperation, and plays a role in guiding the movement of the slider 42. Of course, the slider 42 can also be slidably installed on the housing, which belongs to the protection scope of the utility model.

[0082] like Figure 2 , 12 -13, the housing includes a base 24 and a mounting plate 25 covering the base 24, the mounting plate 25 is connected to the panel 26, the plug assembly 1, the terminal 22, the protective door 23, the pressure plate 21 and the adjustment device are respectively arranged in the base 24, the worm 43 is provided with a roller 47 for driving the worm 43 to rotate, the roller 47 is provided with a plurality of grooves or convex patterns for increasing the friction force, the mounting plate 25 and the panel 26 are respectively provided with a first through hole 471 and a second through hole 472, the roller 47 passes through the mounting plate 25 and the panel 26 from the first through hole 471 and the second through hole 472 and extends out of the housing, the roller 47 can be directly moved to drive the worm 43 to rotate, and has the characteristic of being easy to operate. Of course, the roller 47 may not be exposed, or the roller 47 may not be arranged, and the worm 43 may be controlled to rotate by inserting a tool such as a screwdriver into the housing, which all belong to the protection scope of the utility model.

[0083] like Figure 11-12As shown, the mounting plate 25 is provided with two opposite fixing plates 481, and the two fixing plates 481 are respectively provided with a slot 482, and the roller 47 and the worm 43 are arranged between the two rotating shafts 483, and the two rotating shafts 483 are respectively inserted into the slots 482 of the two fixing plates 481, so that the roller 47 and the worm 43 are rotatably installed between the two fixing plates 481. Of course, the worm 43 can also be installed on the pressing plate 21 or the base 24, which all belong to the protection scope of the present utility model.
