DETAILED DESCRIPTION

[0025] In order to facilitate those skilled in the art to understand the present invention, the present invention will be further described in detail below with reference to specific embodiments and drawings.

[0026] Example 1

[0027] Reference Figure 1-6 The present invention provides a multifunctional combination socket, comprising a housing 1, the multifunctional combination socket including a single-phase plug-in module 2 and a three-phase plug-in module 3 disposed within the housing 1. The housing 1 comprises a lower shell 11 and an upper shell 12 connected to the lower shell 11. The upper shell 12 is provided with a first opening 121 and a second opening 122. The single-phase plug-in module is mounted in the first opening 121, and the three-phase plug-in module 3 is mounted in the second opening 122.

[0028] The three-phase plug-in module 3 includes a mounting box 31 connected to the housing 1, and a top cover 32 connected to the mounting box 31. The lower end surface of the mounting box 31 is provided with four first mounting areas 33, and the first mounting areas 33 are provided with three-phase conduction components 34. The first mounting area is formed by a plurality of retaining walls provided on the lower end surface of the mounting box 31, so that the distribution of the first mounting areas 33 conforms to the distribution of the plug pins of a three-phase plug. In this embodiment, the top cover 32 and the top surface of the upper shell 12 are flush. A three-phase plug has four plug pins, three of which are vertical and one is horizontal. The four three-phase conduction components 34 correspond to the four plug pins.

[0029] The three-phase conduction assembly 34 includes a three-phase conduction spring 341 disposed within the first mounting area 33 and a terminal 342 connected to the three-phase conduction spring. In this embodiment, the terminal 342 is tubular, with a fixing screw attached to the side wall of the terminal 342. When connecting a power cord, the power cord is inserted into the terminal 342 and the fixing screw secures the power cord to the inner wall of the terminal 342, establishing conduction.

[0030] The bottom surface of the mounting box 31 is provided with a first wire hole 35 that matches the terminal 342. The terminal 342 is connected to the first wire hole 35, and the power cord enters the terminal 342 after passing through the first wire hole 35. The bottom surface of the lower housing 11 is provided with a three-phase plug hole 111 at a position corresponding to the three-phase conductive spring. A three-phase plug is inserted from one side of the lower housing 11 and contacts the three-phase conductive spring for conduction.

[0031] The upper shell 12 is provided with a second connecting wall 124 at a position corresponding to the second opening 122. A limiting flange 125 is provided on the inner side of the second connecting wall 124. One end of the limiting flange 125 protrudes upward to form a plug-in portion 126. The installation box 31 is provided with an inserting port 36 that matches the plug-in portion 126. Figure 1 From the perspective of , there are two first connecting walls 123, which are respectively arranged on the left and right sides of the second opening 122, and the plug-in portion 126 is located on the rear side. The plug-in portion 126 is generally triangular, and the top of the plug-in portion 126 constitutes an arc-shaped concave portion. A circular connecting area is formed between the concave portion and the plug-in port 36. A connecting portion is provided at a position corresponding to the connecting area of ​​the upper cover 32, so that the upper cover 32 can rotate relative to the installation box 31. In addition, a screw installation position is provided on the front side of the upper cover 32 to facilitate locking and fixing the upper cover 32 and the installation box 31.

[0032] The single-phase plug-in module includes a base box 21, a protective assembly 22 connected to the base box 21, and a top cover 23 connected to the top of the base box 21. The base box 21 is provided with a number of partition walls, which divide the interior of the base box 21 into at least one second mounting area 24 and two third mounting areas 25. The second mounting area 24 is provided with a vertical spring 26, and the third mounting area 25 is provided with an angled spring 27. In this embodiment, the single-phase plug-in module can be connected to both a two-pin plug and a three-pin plug. Therefore, the second mounting area 24 is provided with three corresponding to the two plug pins of a two-pin plug and the vertical plug pin of a three-pin plug. The third mounting area 25 is provided with two corresponding to the two angled plug pins of a three-pin plug. The three second mounting areas 24 are arranged side by side, and thus the three vertical springs 26 are arranged side by side. That is, the spring layout of this embodiment can only accommodate one type of plug and cannot accommodate two plugs at the same time. Of course, if it is necessary to accommodate two plugs at the same time, the size of the single-phase plug-in module and the distribution of the second mounting areas 24 can be adaptively changed.

[0033] The protection assembly 22 includes a protection plate 221 connected to the bottom box, a first protection member 222 and a second protection member 223 movably connected to the protection plate 221 , and an elastic member 224 is connected between the first protection member 222 and the second protection member 223 . In this embodiment, the first protective member 222 is used to cover the two vertical springs 26 corresponding to the two-pin plug, and the second protective member 223 is used to cover the vertical spring 26 and the oblique spring 27 corresponding to the three-pin plug. The first protective member 222 is provided with an inclined surface at the position corresponding to the vertical spring 26, and the second protective member 223 is also provided with an inclined surface at the position corresponding to the vertical spring 26 (matching the vertical spring 26 of the three-pin plug). The inclined surface of the first protective member 222 and the inclined surface of the second protective member 223 are in opposite directions. Therefore, when the plug pins of the plug contact the inclined surfaces, the two protective members can move in different directions. That is, when the plug pins of the two-pin plug contact the inclined surface of the first protective member 222, the first protective member 222 moves in one direction to avoid, thereby allowing the plug pins to enter the bottom box 21 and contact and conduct with the vertical spring 26. When the plug pins of the three-pin plug contact the inclined surface of the second protective member 223, the second protective member 223 moves in the opposite direction to avoid. In this embodiment, the elastic member 224 is a spring. Under the elastic force of the spring, the first protective cover contacts one inner wall of the bottom box 21 in the initial state, and the second protective cover contacts the other inner wall on the opposite side.

[0034] The sidewalls of the bottom box 21 are provided with a first engaging portion 211, and the top cover 23 is provided with a corresponding engaging portion at a position on the top cover 23. The engaging portion and the engaging portion 231 cooperate to securely connect the bottom box 21 and the top cover 23. The engaging portion 231 is provided on two opposing sidewalls of the top cover 23.

[0035] The upper shell 12 is provided with a first connecting wall 123 surrounding the first opening 121. A limiting platform 127 is provided on the inner side of the first connecting wall 123. The top cover 23 is provided with a second engaging portion 232 that matches the first connecting wall 123 (the second engaging portion 232 is provided on two other side walls of the top cover 23 adjacent to the card interface 231). In this embodiment, a connecting arm extends downward from the side wall of the top cover 23, and the second engaging portion 232 is provided on the first connecting arm. In this embodiment, the first opening 121 is generally rectangular, so that the first connecting wall 123 surrounds the same shape. Four limiting platforms 127 are provided, one at each corner. The limiting platforms 127 support the bottom box 21 of the single-phase plug-in module. After the single-phase installation module is installed in the first opening 121, the bottom surface of the side wall of the upper cover 32 contacts the limiting platform 127, and the second engaging portion 232 engages the bottom surface of the first connecting wall 123.

[0036] The bottom of the mounting box 31 has a second wire hole 37, and a wire stop 38 is provided on the lower end of the mounting box 31 at a position corresponding to the second wire hole 37. The second wire hole 37 facilitates the introduction of the power cord into the housing 1, thereby achieving electrical connection with the single-phase plug-in module. The wire stop 38 restricts the position of the power cord and guides it to the single-phase plug-in module 2.

[0037] In this embodiment, two single-phase plug-in modules are provided, and one three-phase plug-in module 3 is provided. The three-phase plug-in module 3 is placed in the middle, and the two single-phase plug-in modules are located on either side of the three-phase plug-in module 3. The single-phase plug-in module 2 of this utility model covers a voltage range of 220-250V and a current of 16A, while the three-phase plug-in module 3 covers a voltage range of 380-440V and currents of 16A, 32A, and 64A. This utility model is suitable for scenarios requiring equipment with multiple different voltages, such as intelligent automated production lines.

For example, one single-phase plug-in module and one three-phase plug-in module 3 can be provided, or two single-phase plug-in modules and two three-phase plug-in modules 3 can be provided. The remaining structure is the same as that of Example 1 and will not be described again here.

[0040] The utility model is provided with a single-phase plug-in module and a three-phase plug-in module 3 on the housing 1, so that one socket can simultaneously meet the voltage requirements of equipment with a voltage requirement of 220-250V and equipment with a voltage requirement of 380V-440V. There is no need to separately set up single-phase sockets and multi-phase sockets, which reduces the use of power cords, reduces wiring difficulty, improves safety and saves space, and can well adapt to the needs of automated production lines with various types of equipment.
