Abstract
Description
Technical Field
[0001] The present application relates to the technical field of electric power engineering, and more specifically, to a socket with a locking function. Background Art
[0002] The socket mainly includes a shell and a socket module. The socket module is connected to the power input terminal through the internal reed electrode. The shell has a socket that matches the pin of the plug. The pin of the plug passes through the socket and is electrically connected to the reed electrode in the socket module. During use, due to long-term use of the equipment, mechanical vibration, human movement and other reasons, the plug will become loose or leak, resulting in poor contact of the plug, insufficient current and other problems, and causing damage to the electrical appliances, and even causing electric shock, fire and other electrical risks.
[0003] The common sockets on the market currently rely solely on the elasticity of the reed electrode to clamp the pins, but the excessive elasticity of the reed electrode makes it difficult to insert the pins. Since the plug needs to be frequently plugged in and out due to the change of usage scenarios, the plug pins are easily deformed. At the same time, the contact pressure between the pins and the reed electrode gradually decreases during use, that is, the friction force decreases. Under the impact of external force, the reed electrode cannot provide a large enough clamping effect, making the plug easy to fall off; secondly, the wires connected to the plug are easily affected by external factors, making it difficult to ensure the stability of power supply.

[0031] The embodiment of the present application provides a socket with a locking function, which can solve the problem that the plug is easy to fall off after being inserted into the socket, thereby ensuring the safety of electricity use.
[0032] In order to enable those skilled in the art to better understand the scheme of the present invention, the technical scheme in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention.

[0033] The terms "first", "second", "third", "fourth", etc. in the specification and claims of the present invention and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchanged where appropriate, so that the embodiments described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions, for example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units clearly listed, but may include other steps or units that are not clearly listed or inherent to these processes, methods, products or devices.
[0034] For ease of understanding, the socket module in the embodiment of the present application is described below. Figure 1 and Figure 2An embodiment of the socket module in the embodiment of the present application includes a shell 1, a socket body 2 and a locking mechanism 3. The socket body 2 and the locking mechanism 3 are both installed in the shell 1. The locking mechanism 3 is used to lock the plug pins inserted into the socket body 2 to solve the problem that the plug is easy to fall off after being inserted into the socket, thereby ensuring the safety of electricity use.
[0035] The housing 1 includes a socket cover and a socket box. The socket box has a receiving cavity for receiving the socket body 2. The socket cover is snap-fitted with the socket box. The housing 1 is provided with a socket 11 for the pins to pass through. In this embodiment, a three-hole socket module is used as an example for explanation. There are three sockets 11 and they are all located on the socket cover.
[0036] Reference Figure 2 and Figure 3 The socket body 2 includes a bracket 21, a slider bin 23, a limit frame 24 and a plug sleeve 22. The slider bin 23 and the limit frame 24 are fixed to the housing 1 at one end close to the bracket 21 by a snap-fit connection, and the slider bin 23 and the limit frame 24 are coaxially connected at one end away from the bracket 21. The slider bin 23 and the limit frame 24 are slidably connected by a slide groove and a slide rail. The slider bin 23 and the limit frame 24 are respectively located on both sides of the bracket 21 and are arranged to enclose the bracket 21 to limit the circumference of the bracket 21. Further, the limit frame 24 is provided with a bearing area for bearing the bracket 21. The bracket 21 is located between the socket cover and the limit frame 24. The bracket 21 is limited in the vertical direction by the bearing area on the socket cover and the limit frame 24 to achieve stable installation of the bracket 21.
[0037] Reference Figure 3 and Figure 4 In the present embodiment, three sockets 22 are provided, namely, a live pole socket 22, a neutral pole socket 22 and a ground pole socket 22. The sockets 22 are provided at positions corresponding to the sockets 11 on the bracket 21. The sockets 22 and the bracket 21 are mutually engaged, and the pins pass through the sockets 11 and enter the sockets 22 for electrical connection.
[0038] See also Figure 2 , Figure 3 and Figure 5The locking mechanism 3 includes a clamping assembly 31 and a driving assembly 32. The driving assembly 32 is used to drive the clamping assembly 31 to clamp or unlock the pins. The clamping assembly 31 is located between the bracket 21 and the limiting frame 24. The limiting frame 24 is provided with a limiting platform 241. The limiting platform 241 is located at one end of the clamping assembly 31 away from the bracket 21. One end of the clamping assembly 31 contacts the bracket 21, and the other end of the clamping assembly 31 contacts the limiting platform 241. The bracket 21 and the limiting frame 24 cooperate to limit the clamping assembly 31 along the plug-in and pull-out direction of the pin, that is, the Z-axis direction. In this embodiment, the clamping assembly 31 is provided with two groups, which are used to clamp the hot electrode pins and the zero-pole pins. The two groups of clamping assemblies 31 are arranged side by side along the X-axis direction. The two groups of clamping assemblies 31 are driven by a group of driving assemblies 32 to simultaneously lock the hot electrode pins and the zero-pole pins.
[0039] Specifically, the clamping assembly 31 includes a first clamping jaw 311 and a second clamping jaw 312, which are arranged opposite to each other and form a clamping space 313, the socket 22 and the clamping space 313 are arranged one by one and the pins entering the socket 22 are simultaneously located in the clamping space 313, and the driving assembly 32 drives the first clamping jaw 311 and the second clamping jaw 312 to move toward each other to adjust the clamping space 313 to clamp the pins. In this embodiment, in each set of clamping assemblies 31, the first clamping jaw 311 and the second clamping jaw 312 move toward each other along the X-axis under the action of the driving assembly 32 or move away from each other under the action of the insertion of the pins; the clamping assembly 31 and the socket 22 corresponding to one pin are arranged side by side along the Y-axis direction, so that the pins entering the socket 22 are simultaneously located in the clamping space 313, so as to realize the power connection and locking of the pins at the same time. After the plug is connected to the socket, the pin enters the socket 22 through the socket 11 for electrical connection, and the driving module drives the first clamping jaw 311 and the second clamping jaw 312 to move toward each other to reduce the clamping space 313, and the pin located in the socket 22 is pressed against each other by the first clamping jaw 311 and the second clamping jaw 312 to lock the pin, thereby ensuring that the pin cannot be separated from the socket 22.
[0040] See also Figures 2 to 6The driving assembly 32 includes a transmission module 321, a sliding block 322 and a resilient member 323. The transmission module 321 is arranged on the housing 1. The transmission module 321 drives the sliding block 322 to move toward the bracket 21. The resilient member 323 is arranged between the sliding block 322 and the bracket 21 to push the sliding block 322 to move away from the bracket 21 to return to its original position. The sliding block 322 is arranged in the sliding bin and is connected by sliding along the sliding bin. Specifically, the slider bin 23 is provided with a slide rail, and the sliding block 322 is provided with a slide groove that matches the slide rail. The length directions of the slide rail and the slide groove are consistent with the plug-in and unplug direction of the plug. The slider bin 23 provides an installation base for the sliding block 322. At the same time, the movement direction of the sliding block 322 is guided by the cooperation of the slide rail and the slide groove, so as to ensure that the sliding block 322 accurately slides toward the bracket 21 under the action of the transmission module 321.
[0041] See also Figure 3 and Figure 5 The sliding block 322 is provided with a guide groove 3221 for accommodating the clamping assembly 31. The guide groove 3221 is provided with a guide slope 3222 that fits the end surface of the first clamping jaw 311 and the second clamping jaw 312 away from the clamping space 313. The guide slope 3222 is V-shaped. Under the premise of the Z-axis limit, the clamping assembly 31 limits the possibility of synchronous movement of the clamping assembly 31 and the sliding block 322. Therefore, the sliding block 322 moves along the Z-axis direction under the action of the transmission module 321. The sliding block 322 moves the first clamping jaw 311 and the second clamping jaw 312 toward each other along the guide slope 3222, that is, moves along the X-axis direction to adjust the size of the clamping space 313.
[0042] See also Figure 6 The resilient member 323 is preferably a spring. The resilient member 323 is compressed or rebounded along the Z-axis direction. One end of the resilient member 323 is connected to the sliding block 322, and the other end is connected to the bracket 21. In this embodiment, the sliding block 322 is provided with a mounting groove for mounting the resilient member 323, and one end of the resilient member 323 connected to the sliding block 322 is mounted in the mounting groove. When the transmission module 321 drives the sliding block 322 to move toward the direction of the bracket 21 to reduce the clamping space 313 to clamp the pin, the resilient member 323 is compressed by the sliding block 322, and the resilient member 323 plays the role of buffering the force between the sliding block 322 and the bracket 21. When the transmission module 321 drives the sliding block 322 to move away from the bracket 21 to expand the clamping space 313 to unlock the pin, the resilient member 323 uses its own rebound force to push the sliding block 322 back to its original position.
[0043] See also Figure 2 and Figure 5The transmission module 321 includes a handle 3211, a driving gear 3212, a driven gear 3213 and a cam 3214. The driving gear 3212 is rotatably mounted on the housing 1 through an axis. The handle 3211 is coaxially connected with the driving gear 3212. The driven gear 3213 is coaxially and fixedly connected with the cam 3214. The driving gear 3212 and the driven gear 3213 are meshed. The cam 3214 drives the sliding block 322 to move closer to the bracket 21. The driven gear 3213, the cam 3214, the end of the sliding bin away from the bracket 21 and the end of the limiting frame 24 away from the bracket 21 are coaxially connected. The cam 3214 is located between the sliding bin and the limiting frame 24, and the cam 3214 is rotatably matched with the end of the sliding bin away from the bracket 21 and the end of the limiting frame 24 away from the bracket 21. Apply force to rotate the handle 3211, the handle 3211 synchronously rotates the driving gear 3212, the driving gear 3212 engages with the driven gear 3213 to drive the driven gear 3213 to rotate, the driven gear 3213 rotates to drive the cam 3214 to rotate synchronously, and then the cam 3214 drives the sliding block 322 to move closer to the bracket 21.
[0044] See also Figure 5 and Figure 7 In order to enhance the durability between the driving assembly 32 and the clamping assembly 31, the transmission module 321 also includes a spring sheet 3215, which is arranged on the sliding block 322. The spring sheet 3215 is fixed to the sliding block 322 through a snap-in groove. One end of the spring sheet 3215 is fixedly connected to the sliding block 322, and the other end contacts and presses the cam 3214. The cam 3214 and the sliding block 322 are flexibly connected through the spring sheet 3215. In this embodiment, the spring sheet 3215 has a mounting portion and a deformation portion, and the deformation portion and the mounting portion are integrally formed; the mounting portion is a plane, which is used to increase the contact area between the spring sheet 3215 and the sliding block 322, and the deformation portion is bent, and the deformation portion has a tendency to deform toward the mounting portion, and the rigid connection between the cam 3214 and the sliding block 322 is converted into a flexible connection through the spring sheet 3215, so that the sliding block 322 drives the clamping assembly 31 to adapt to pins of different thicknesses, and does not cause damage to the clamping assembly 31 and the driving assembly 32. When a force is applied to the deformation portion, the deformation portion moves synchronously with the mounting portion on the one hand to transmit the force from the cam 3214 to the sliding block 322, so that the sliding block 322 moves toward the bracket 21, and at the same time, the deformation portion deforms toward the mounting portion to buffer the force of the cam 3214 acting on the sliding block 322.
[0045] Furthermore, the bracket 21 is provided with a limit block 211, and the sliding block 322 is provided with a limit slot 3223. The length direction of the limit slot 3223 is consistent with the movement direction of the sliding block 322. The two ends of the limit slot 3223 are arranged to penetrate. The limit slot 3223 accommodates the limit block 211 so that the sliding block 322 and the bracket 21 can slide and cooperate. The spring piece 3215 is located at the end of the limit slot 3223 away from the bracket 21. When the cam 3214 drives the spring piece 3215 and the sliding block 322 to move synchronously toward the bracket 21, the spring piece 3215 and the limit block 211 are pressed to limit the sliding block 322 from continuing to move. When the spring piece 3215 and the limit block 211 are pressed, the sliding block 322 is in the maximum range of motion, so as to prevent the sliding block 322 from excessively moving and causing damage to the clamping assembly 31.
[0046] In order to realize reciprocating movement of the sliding block 322 along the Z-axis to adjust the angle clamping space 313 to realize switching between the clamping and unlocking states, the cam 3214 includes a first abutment portion and a second abutment portion. The distance between the first abutment portion and the axis center of the cam 3214 is different from the distance between the second abutment portion and the axis center of the cam 3214. The cam 3214 presses against the first abutment portion and the second abutment portion respectively to realize compression and extension of the spring piece 3215. In this embodiment, the distance between the first abutting portion and the axis of the cam 3214 is greater than the distance between the first abutting portion and the axis of the cam 3214. When the deformed portion of the spring sheet 3215 contacts the first abutting portion, the distance between the axis of the cam 3214 and the sliding block 322 increases, the spring sheet 3215 is compressed and drives the sliding block 322 to move closer to the bracket 21 so that the first clamping jaw 311 and the second clamping jaw 312 move toward each other along the guide inclined surface 3222 to clamp the pin; when the cam 3214 rotates, when the deformed portion of the spring sheet 3215 contacts the second abutting portion, the distance between the axis of the cam 3214 and the sliding block 322 decreases, the spring sheet 3215 extends, and the sliding block 322 moves away from the bracket 21 to release the limit between the first clamping jaw 311 and the second clamping jaw 312 and unlock the pin, making it easy to pull out the pin. The cam 3214 contacts the spring piece 3215 in a gradual manner by pressing the first abutting portion and the second abutting portion respectively, so as to enable the sliding block 322 to slide back and forth along the Z axis, thereby adjusting the clamping space 313 of the clamping assembly 31 to clamp the pin or unlock the pin.
[0047] See also Figure 7When the locking cam 3214 is in the unlocking state, the locking cam 3214 will be unlocked and the locking cam 3214 will be unlocked, so that the first and second locking cams 3214 can be unlocked and the like. When the block passes over the flange and disengages from the locking area as the cam 3214 rotates in the opposite direction of the handle 3211, the flange releases the lock on the block, and the corresponding cam 3214 rotates in the opposite direction so that the second abutment portion contacts the spring piece 3215, and the sliding block 322 moves in the direction away from the bracket 21. The sliding block 322 releases the limitation of the first clamping jaw 311 and the second clamping jaw 312 on the X-axis, thereby releasing the lock of the clamping assembly 31 on the pin, making it easier to pull out the plug.
[0048] In order to effectively protect children from touching and prevent electric shock accidents, the socket body 2 is also provided with a safety door 25, and the bracket 21 is provided with a through hole 212, which is provided corresponding to the socket 22 and the clamping assembly 31, and the safety door 25 is installed on the bracket 21 and blocks the through hole 212. The safety door 25 can be deformed, and when a force is applied to the plug, the pin passes through the socket 11 and presses against the safety door 25, so that the safety door 25 is deformed to expose the through hole 212 for the pin to enter, and the safety door 25 is made of PC flame retardant material.
