DETAILED DESCRIPTION

The embodiments of the utility model are further described below in conjunction with the accompanying drawings.

As shown in the figure, a plug-in board with replaceable functional modules includes a base plate 1 , a cover plate 2 and a plurality of functional modules 3 .

The bottom plate 1 is provided with a plurality of module installation positions 11, and two conductive plates 4 are fixedly installed on the bottom plate 1. The two conductive plates 4 extend from positions corresponding to the module installation positions 11 to form bent plug ports 41. The bottom plate 1 is elongated as a whole, and the module installation positions 11 are evenly spaced along the length direction of the bottom plate 1. The two conductive plates 4 are correspondingly arranged on both sides of the bottom plate 1 and are used for wiring and conducting electricity of the N pole and the L pole, respectively.

Two plug-in plates 31 extend from the bottom of the functional module 3, which are used for N-pole and L-pole wiring and conduction respectively. The plug-in plates 31 correspond to the plug-in ports 41. When the functional module 3 is installed in the module installation position 11, it can be plugged and connected with the plug-in port 41 of the conductive plate 4 through the plug-in plates 31.

The cover plate 2 is detachably connected to the bottom plate 1, and the cover plate 2 is limitedly matched with the functional module 3, and a through slot 21 corresponding to the functional module 3 is formed on the cover plate 2. The functional module 3 is in a "convex" shape, and the upper end of the functional module 3 is adapted to the through slot 21 and extends from the through slot 21, which not only further realizes the positioning of the functional module 3, but also makes the structure more stable and the appearance beautiful.

The above-mentioned plug-in board functional module is very convenient to disassemble, assemble and replace. When disassembling, assembling and replacing the functional module, first open the cover plate, and then the functional module can be quickly disassembled, assembled and replaced by plugging and unplugging. Then, cover the cover plate to stably restrict the functional module on the bottom plate. It is not only convenient to disassemble and assemble, but also has a stable structure. In addition, the functional module is embedded in the bottom plate, making the plug-in board as a whole lighter and thinner, and the appearance is more beautiful.

Furthermore, buckles 12 are installed on both sides of the base plate 1 corresponding to the module installation position 11, and the buckles 12 can be snapped with the functional module 3. The buckle 12 is in the shape of a "7", and a buckle groove is formed on the convex shoulder of the functional module 3. The buckle can buckle the convex shoulder of the functional module 3, thereby ensuring that the functional module 3 is more stably installed in the module installation position 11, and the structure is more reliable.

The bottom plate 1 is provided with positioning grooves 13 on both sides thereof which are adapted to the conductive plate 4. The conductive plate 4 is positioned in the positioning grooves 13, and a positioning pressure plate 14 which can basically cover the conductive plate 4 is provided outside the positioning grooves 13. The positioning grooves 13 facilitate the positioning and installation of the conductive plate 4. The positioning pressure plate 14 can be fixedly installed on the bottom plate 1 by screws and presses the conductive plate 4, which not only ensures the stable installation of the conductive plate 4, but also shields the conductive plate 4 to improve safety. Of course, the positioning pressure plate 14 forms a socket corresponding to the position of the plug interface 41 to ensure the normal plug connection between the plug interface 41 and the functional module 3.

Terminal frames 15 are provided at both ends of the bottom plate 1, and wiring terminals 42 connected to the terminal frames 15 are extended from the ends of the conductive plates 4, which facilitate the wiring connection of the conductive plates 4. The terminal frames 15 are also provided with an openable protective plate 16, which can be rotatably connected to the terminal frames 15. After the wiring is completed, the protective plate 16 can be covered to shield the terminal frames to improve safety.

A grounding plate 5 is also provided at the bottom of the base plate, and both ends of the grounding plate 5 are also connected to the terminal frame. A connecting hole 17 is correspondingly formed on the module mounting position 11. When the functional module is installed to the module mounting position 11, it can be conveniently grounded, making the power supply of the plug board safer.

The side of the bottom plate 1 corresponding to the module installation position 11 is provided with a plurality of threading holes 18. In addition to the conventional socket module, the functional module 3 can also use a switch module. When the switch module is used, the power cord of the appliance can be extended into the bottom plate through the threading hole 18 and connected to the switch module, and the switch module directly controls the appliance.

There are many ways to connect the cover plate 2 and the base plate 1, such as snap connection, screw connection, etc. In order to facilitate the disassembly and replacement of functional modules, it is best to use a connection structure that is easy to disassemble and assemble between the cover plate 2 and the base plate 1.

The cover plate 2 comprises an inner shell 201 and an outer shell 202, wherein the outer shell 202 is sleeved outside the inner shell 201, and a receiving cavity 22 is formed at both ends of the cover plate 2, wherein a locking mechanism is arranged in the receiving cavity 22. The locking mechanism 6 comprises a locking tongue 61, a button 62, a transmission gear 63, and a reset elastic member 64, wherein two locking tongues 61 are provided, and the two locking tongues 61 are slidably arranged and extend to both sides of the receiving cavity 22 respectively, and the button 62 is also slidably arranged, one end of which protrudes to the outside of the cover plate 2, and the other end is matched with the locking tongue 61 through the transmission gear 63, and the reset elastic member 64 is a spring, and its two ends are respectively connected to the cover plate 2 and the locking tongue 61, and can provide a reset elastic force.

The bottom plate 1 is provided with positioning slots 19 corresponding to the locking tongue 61 at both ends. When the cover is mounted on the bottom plate, the cover is sleeved outside the bottom plate, and the locking tongue 61 of the locking mechanism 6 is inserted into the positioning slots 19 to achieve locking and fixing. When the cover needs to be removed, the button 62 is pressed, and the button slides to drive the transmission gear 63 to rotate. The transmission gear 63 rotates to drive the locking tongue 61 to compress the spring and move inward, so that the locking tongue 61 is separated from the positioning slots 19 to achieve unlocking. At this time, the cover can be easily removed, and the disassembly and assembly operation is very convenient.
