Description

Technical Field

[0001] The present invention relates to the technical field of sockets, and in particular to a flat socket with a switch. Background Art

[0002] For traditional sockets with switches, the button part of the switch protrudes from the surface of the socket panel, which hinders the insertion of larger or irregularly shaped plugs, resulting in some plugs not being inserted properly.

[0003] In addition, for such sockets, since the switch protrudes from the surface of the socket panel, it is rather obtrusive and not aesthetically pleasing.

[0004] Furthermore, for conventional sockets with switches, generally the on-off state of the socket is reflected by the pressed and popped-up states of the switch, and usually there is no other more obvious indication structure, so the powered-on state of the socket cannot be more intuitively displayed.

[0031] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0032] As shown Figures 1 to 9 is a socket, including a base 1 (i.e., a housing, including an upper shell and a lower shell), on which a jack assembly 2 and a switch assembly 3 for controlling the on / off of the jack assembly 2 are provided. The jack assembly 2 is a two-phase jack (including a two-hole jack and a three-hole jack, the two-hole jack has a live jack and a neutral jack, and the three-hole jack has a live jack, a neutral jack and a ground jack) or a three-phase jack (a four-hole jack). The switch assembly 3 is connected between an external wire and one of the jacks (such as the switch assembly 3 is connected between the live wire of the mains and the live jack of the jack assembly 2), and the switch of the switch assembly 3 controls the on / off of the jack assembly 2 and the external wire.

[0033] Above the base 1, there is a socket top cover 4 facing the position of the jack assembly 2. The switch assembly 3 includes a button top cover 5 provided on one side of the socket top cover 4. When the switch assembly 3 is turned on and off, the upper end surfaces of the button top cover 5 are at the same height and are both lower than the upper end surface of the socket top cover 4 or flush with the upper end surface of the socket top cover 4. That is, in the on and off states of the switch assembly 3, the button top cover 5 will reset (press the button top cover 5 once, the switch assembly 3 is turned on, and then the button top cover 5 resets; press the button top cover 5 again, the switch assembly 3 is closed, and then the button top cover 5 resets again), and after resetting, the upper end surface of the button top cover 5 is lower than the upper end surface of the socket top cover 4 or flush with the upper end surface of the socket top cover 4. In this way, the button top cover 5 will not protrude from the socket top cover 4 and will not interfere with the insertion of the plug. Plugs with larger sizes or irregular shapes can also be inserted.

[0034] Of course, the upper end surface of the button top cover 5 is preferably flush with the upper end surface of the socket top cover 4, which is more beautiful.

[0035] In a more specific embodiment of the present invention, as Figure 2 shown, one end of the button top cover 5 is rotatably connected to the base 1 (preferably hinged), and the switch is turned on and off by pressing the other end (the rear end in the figure) of the button top cover 5. A first limiting structure for limiting the upward swing angle of this end of the button top cover 5 is provided between the other end (the rear end in the figure) of the button top cover 5 and the base 1. The first limiting structure can limit the button top cover 5 so that it cannot protrude from the socket top cover 4 when resetting.

[0036] More specifically, the first limiting structure includes an insert plate 51 provided on the button cover 5 and extending downward, and a socket 11 provided on the base 1, wherein the insert plate 51 is inserted into the socket 11 from top to bottom and can move up and down along the socket 11, and a limiting undercut 511 is provided at the lower end of the insert plate 51 to block below the socket 11. The cooperation between the insert plate 51 and the socket 11 has a guiding function on the one hand, so that the up and down movement of the rear end of the button cover 5 is smoother and more accurate without being skewed; on the other hand, it has a limiting function, that is, when the rear end of the button cover 5 pops up, the limiting undercut 511 blocks below the socket 11 to prevent the button cover 5 from protruding from the socket cover 4.

[0037] Furthermore, the first limiting structure also includes a limiting extension plate 52 arranged on the button top cover 5 and extending to the bottom of the socket top cover 4. When the rear end of the button top cover 5 pops up, the socket top cover 4 blocks the limiting extension plate 52 from above, which can also prevent the button top cover 5 from protruding out of the socket top cover 4.

[0038] The switch assembly 3 also includes a driving member 31 disposed below the button top cover 5, the driving member 31 is slidably connected to the base 1 along the up and down directions, and the base 1 is also movably connected with a swinging member 32 located below the driving member 31 and capable of swinging along an axis in the front-to-back direction, a transmission structure is provided between the driving member 31 and the swinging member 32, which can convert the up and down movement of the driving member 31 into the left and right swinging movement of the swinging member 32, the swinging member 32 is provided with a first conductive sheet 33 that can be connected to an external wire and can swing left and right, the jack assembly 2 is connected to a second conductive sheet 21, and when the swinging member 32 swings left and right, the first conductive sheet 33 and the second conductive sheet 21 are respectively turned on and off.

[0039] The present invention converts the up and down movement of the button top cover 5 into the left and right swing of the first conductive sheet 33, thereby realizing the on and off of the switch. That is, in the present invention, when the button top cover 5 is pressed down, the button top cover 5 presses the driving member 31 downward to make the driving member 31 move downward, and the transmission structure converts the downward movement of the driving member 31 into the left and right swing of the swing member 32. When the swing member 32 swings left and right, it will bring the first conductive sheet 33 to swing left and right, thereby making the first conductive sheet 33 and the second conductive sheet 21 conductive and disconnected. Whether the swing member 32 swings left or right, it does not affect the movement of the button top cover 5, and the button top cover 5 can be reset upward and reset to the same position; and when the button top cover 5 is pressed, the button top cover 5 will trigger the swing member 32 to make its left swing turn right or right swing turn left, thereby making the first conductive sheet 33 and the second conductive sheet 21 conductive and disconnected.

[0040] In a more specific embodiment of the present invention, Figure 5 , Figure 7 , Figure 8As shown, the transmission structure includes a first slider 311 slidably connected to the driving member 31 in the left-right direction. The first slider 311 is provided with a first left inclined surface 3111 and a first right inclined surface 3112. The first left inclined surface 3111 gradually rises from left to right, and the first right inclined surface 3112 gradually rises from right to left.

[0041] A first elastic member 312 is provided in the middle of the driving member 31, which can make the first slider 311 slide towards the middle of the driving member 31. The first elastic member 312 is preferably a spring. As Figure 7 shown, the first elastic member 312 is fixed in the middle of the driving member 31, and the left and right ends of the first slider 311 respectively abut against the left and right ends of the first elastic member 312. In the free state, the first slider 311 is located in the middle of the driving member 31. The first elastic member 312 is mainly used to reset the first slider 311 that has slid to both sides to the middle.

[0042] A second elastic member 313 is provided between the driving member 31 and the base 1 to press the driving member 31 upwards. The second elastic member 313 is preferably a spring. The main function of the second elastic member 313 is to reset the driving member 31 upwards.

[0043] The swinging member 32 is provided with a second left inclined surface 321 that can cooperate with the first left inclined surface 3111 and a second right inclined surface 322 that can cooperate with the first right inclined surface 3112. The second left inclined surface 321 gradually decreases from left to right, and the second right inclined surface 322 gradually decreases from right to left. When the swinging member 32 swings to the left, the second right inclined surface 322 and the first right inclined surface 3112 are vertically opposite; when the swinging member 32 swings to the right, the second left inclined surface 321 and the first left inclined surface 3111 are vertically opposite. Since there are only two static states of the swinging member 32 (detailed later), either it swings to the left or to the right. If the swinging member 32 has swung to the right (as Figure 7As shown in the figure, the second left inclined surface 321 is upturned. When the button top cover 5 is pressed and the driving member 31 moves downward, the first left inclined surface 3111 first contacts and presses against the second left inclined surface 321. Under the pressing action, the first slider 311 moves leftward. When the driving member 31 continues to move downward, the first slider 311 presses downward on the left part (at the position of the second left inclined surface 321) of the swing member 32, causing the driving member 31 to swing leftward. It should be noted that during this process, since the first slider 311 has moved to the left, when the driving member 31 continues to move downward, the first slider 311 will never contact the right part (at the position of the second right inclined surface 322) of the swing member 32. When the button top cover 5 is released, under the action of the second elastic member 313, the driving member 31 and the button top cover 5 both reset upward. Under the action of the first elastic member 312, the first slider 311 resets toward the middle of the driving member 31, but the swing member 32 remains in its state. On the contrary, if the swing member 32 has swung to the left and its second right inclined surface 322 is upturned, when the button top cover 5 is pressed, the first slider 311 presses downward on the right part (at the position of the second right inclined surface 322) of the swing member 32, causing it to swing rightward.

[0044] In a more specific embodiment of the present invention, the front and rear ends of the swing member 32 are rotatably connected to the base 1, that is, the swing member 32 rotates around the axis in the front - rear direction. Preferably, the front and rear ends of the swing member 32 are provided with shaft heads 325, and the shaft heads 325 are inserted into corresponding shaft holes (not shown in the figure) on the base 1 to achieve the rotational connection.

[0045] A second limiting structure for limiting the left - right swing angle of the swing member 32 is provided between the swing member 32 and the base 1. The second limiting structure has multiple structures, and one of them is as Figure 5 shown in the figure. At the shaft head 325 at the rear end of the swing member 32, there are two first limiting surfaces 3251 distributed in a figure - eight shape, and at the corresponding shaft hole on the base 1, there are also two second limiting surfaces in a figure - eight shape (not shown in the figure). Moreover, the opening angle of the two second limiting surfaces is greater than the opening angle of the two first limiting surfaces 3251, and the swing member 32 can only swing between the two second limiting surfaces.

[0046] In a more specific embodiment of the present invention, as Figure 5 、 Figure 8 shown, a fixing piece 331 capable of connecting with an external wire is provided below the first conductive sheet 33. The lower end of the first conductive sheet 33 is rotatably connected or abutted against the fixing piece 331 and can swing left - right relative to the fixing piece 331. A third elastic member 34 for pressing the first conductive sheet 33 downward is provided between the first conductive sheet 33 and the swing member 32.

[0047] The third elastic member 34 is preferably a spring.

[0048] In a more specific embodiment of the present invention, a second slider 35 capable of sliding in the up and down direction is slidably connected to the swing member 32. A third elastic member 34 is provided between the second slider 35 and the swing member 32. A V-shaped fork 351 is provided at the lower end of the second slider 35, and the fork 351 straddles the upper end of the first conductive sheet 33.

[0049] The main function of the third elastic member 34 is to ensure that the first conductive sheet 33 can swing to the left to the limit when swinging to the left, so as to make good contact with the second conductive sheet 21.

[0050] In addition, since the swing member 32 is rotatably connected to the base 1, the swing member 32 cannot move upward. Since the fixing piece 331 blocks below the first conductive sheet 33, the first conductive sheet 33 cannot move downward. Therefore, under the pressing action of the third elastic member 34, the first conductive sheet 33 can only swing to the left limit or the right limit (a V-shaped notch is provided at the corresponding position on the base 1, i.e., the housing, and the lower part of the first conductive sheet 33 is restricted in the V-shaped notch, thereby defining the left swing limit and the right swing limit of the first conductive sheet 33), and will not stay in the middle position. That is to say, there are only two static states of the swing member 32, either swinging to the left (the second right inclined surface 322 is upturned) or swinging to the right (the second left inclined surface 321 is upturned).

[0051] In a more specific embodiment of the present invention, since the button top cover 5 will reset in both the on and off states of the switch assembly 3, in order to more intuitively indicate the switch state, the present invention provides an indication structure for indicating the on and off of the jack assembly 2 (i.e., the switch of the switch assembly 3).

[0052] It should be noted that both the switch assembly 3 and the indication structure are pure mechanical components. Therefore, the switch of the present invention has high reliability and long service life.

[0053] The indication structure is driven by the swing member 32, that is, when the swing member 32 swings left and right, it will also drive the indication structure to switch the indication state.

[0054] In a more specific embodiment of the present invention, the indication structure includes an indication swing rod 36, the middle part of which is rotatably connected to the base 1, the swing member 32 is provided with a left baffle 323 and a right baffle 324 which are arranged at intervals, one end of the indication swing rod 36 is inserted between the left baffle 323 and the right baffle 324, the free end of the indication swing rod 36 is provided with at least two different indication marks 361, and the button top cover 5 is provided with an observation window 53 located above the free end of the swing rod for observing the indication marks 361. Since the swing member 32 will swing left and right during the process of pressing the button top cover 5, the present invention utilizes the left and right swing of the swing member 32 to drive the operation of the indication structure. That is, the swing member 32 is provided with a left baffle 323 and a right baffle 324 spaced apart from each other, and one end of the indicating swing rod 36 is inserted between the left baffle 323 and the right baffle 324. When the swing member 32 swings right, the left baffle 323 moves the end of the swing rod 36 close to the left baffle 323 and the right baffle 324 to swing right, and the free end of the indicating swing rod 36 swings left, and the indicating mark 361 close to the right is swung to the right below the observation window 53. Similarly, when the swing member 32 swings left, the right baffle 324 moves the end of the swing rod 36 close to the left baffle 323 and the right baffle 324 to swing left, and the free end of the indicating swing rod 36 swings right, and the indicating mark 361 close to the left is swung to the right below the observation window 53. The indicating structure of the present invention adopts a simple mechanical structure to realize the operation of the indicating structure, has a simple structure, few parts, low cost, and reliable operation.

[0055] More specifically, there are at least two types of indicator marks 361, which are used to distinguish the on and off states of the switch. The two different indicator marks 361 preferably use different colors, such as red and white. When the switch is on, the red indicator mark swings to the bottom of the observation window 53, and the red mark can be observed through the observation window 53; when the switch is off, the white indicator mark swings to the bottom of the observation window 53, and the white mark can be observed through the observation window 53. Of course, the two different indicator marks 361 can also use different texts, such as "on" and "off".

[0056] In the present invention, by pressing the button cover 5, the switch assembly 3 is opened, the socket assembly 2 is powered off, and the button cover 5 is reset; by pressing the button cover 5 again, the switch assembly 3 is closed, the socket assembly 2 is powered on, and the button cover 5 is reset again. The button cover 5 is reset to the same height each time it is pressed, and the height is lower than the upper end surface of the socket cover 4 or flush with the upper end surface of the socket cover 4. Therefore, whether the switch assembly 3 is opened or closed, the button cover 5 will not protrude from the socket cover 4 and will not interfere with the insertion of the plug. Of course, correspondingly, since the switch assembly 3 only needs to press the button cover 5 to open and close, even if the plug is already plugged into the socket, the button cover 5 can still be pressed, and the plug will not interfere with the action of the button cover 5.

[0057] Obviously, the above embodiments of the present invention are merely examples given to clearly illustrate the present invention, rather than limitations on the implementation manners of the present invention. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to enumerate all the implementation manners here. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the claims of the present invention.
