[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] A multifunctional electric energy meter wiring device comprises a base 1, a front end of the base 1 is mounted with a plurality of current pin modules 2, and an upper end of the base 1 is detachably mounted with a plurality of function signal pin modules 3.

[0025] The upper end of the base 1 is evenly and straightly provided with a number of sockets 4 along the length direction for plugging in the functional signal pin module 3. A connecting plate is provided at the bottom of the socket 4, and a number of first conductive contacts are provided on the connecting plate. A main control board is provided in the base 1, and the number of first conductive contacts are connected to the main control board through wires.

[0026] The functional signal pin module 3 includes a plug 5 that matches the socket 4, and a plurality of pins 6 are plugged into the plug 5. The bottom of the plug 5 is provided with a plurality of second conductive contacts that contact the first conductive contacts one by one, and the plurality of second conductive contacts are electrically connected to the plurality of pins 6 in a one-to-one correspondence.

[0027] The above is the prior art. Referring to the patent announcement number "CN216434759U" of "An auxiliary device for energy controller calibration", the lower end of the multi-function electric energy meter has a socket for connecting wires for detecting different functions. The sockets at different positions correspond to the different functions of the multi-function electric energy meter. The several sockets 4 at the upper end of the base 1 correspond to the sockets at different positions of the electric energy meter. After the function signal pin module 3 is inserted into the corresponding socket 4, the corresponding socket at the lower end of the electric energy meter is inserted into the pin 6 of the function signal pin module 3, thereby connecting the multi-function electric energy meter, the signal pin module, the connection board and the different detection modules on the main control board for detection.

[0028] Since the function signal pin module 3 only serves to connect with the multi-function electric energy meter and conduct electricity, the function signal pin module 3 can be inserted into different sockets 4 for universal use. Different multi-function electric energy meters need to detect different functions. In practice, in order to reduce costs, function signal pin modules 3 will not be set in positions where there are no sockets 4. Only a few are needed. During detection, several function signal pin modules 3 are inserted into the corresponding sockets 4 as needed. Therefore, the function signal pin module 3 needs to be frequently plugged in and out of the socket 4.

[0029] The plug 5 is connected to the inner wall of the jack 4 via a limiting structure. After the function signal pin module 3 is inserted into the corresponding jack 4, the limiting structure can prevent the function signal pin module 3 from being pulled out.

[0030] The limiting structure includes a limiting platform 10 and an elastic sheet 11. The limiting platform 10 is protruding from the inner wall of the jack 4 on the rear side. A vertical through groove 9 is provided on the rear side of the plug 5. The width of the groove 9 is not less than the width of the limiting platform 10. The position of the limiting platform 10 corresponds to the position of the groove 9, so that when the plug 5 is plugged in or out of the jack 4, the limiting platform 10 is located in the groove 9, and the plug 5 will not be blocked by the limiting platform 10. The elastic sheet 11 is located in the groove 9, and the lower end of the elastic sheet 11 is fixed in the groove 9 close to the lower end of the plug 5. The upper end of the elastic sheet 11 is inclined toward the rear and abuts against the lower end of the limit platform 10. The depth of the groove 9 is not less than the sum of the horizontal length of the limit platform 10 and the thickness of the elastic sheet 11. Therefore, when the plug 5 is inserted into the jack 4, the elastic sheet 11 is squeezed by the limit platform 10 and deflected toward the front, so that the elastic sheet 11 can smoothly pass the position of the limit platform 10. After the plug 5 is inserted to the bottom, the elastic sheet 11 passes the position of the limit platform 10, and the elastic sheet 11 loses the squeeze and rebounds toward the rear through elasticity, so that the upper end of the elastic sheet 11 abuts against the lower end of the limit platform 10.

[0031] The rear end of the base 1 is provided with an extrusion structure for extruding the elastic sheet 11 toward the front. The extrusion structure has an elastic reset structure and is used to squeeze the elastic sheet 11 when the functional signal needle module 3 needs to be taken out.

[0032] After the functional signal needle module 3 is inserted into the corresponding socket 4, the upper end of the elastic sheet 11 abuts against the lower end of the limit platform 10, thereby restricting the functional signal needle module 3 in the socket 4, and the functional signal needle module 3 is not easily pulled out by the electric energy meter; when the functional signal needle module 3 needs to be pulled out, the elastic sheet 11 is squeezed forward by the extrusion structure, so that the upper end of the elastic sheet 11 is staggered with the limit platform 10, so that the functional signal module can be pulled out from the socket 4, and then the extrusion mechanism is reset under the drive of the elastic reset structure.

[0033] A preferred technical solution, the extrusion structure includes a horizontally arranged ejector pin 13, each socket 4 is correspondingly provided with a ejector pin 13, the rear end of the base 1 is provided with a sliding hole extending forward and communicating with the socket 4, the sliding hole matches the ejector pin 13, the ejector pin 13 is slidably installed in the sliding hole, the ejector pin 13 is located below the limit platform 10, the front end of the ejector pin 13 extends into the socket 4 and abuts against the elastic sheet 11, the front end of the ejector pin 13 is fixed with a limiting head 15 whose size is larger than the sliding hole, and the rear end of the ejector pin 13 extends out of the sliding hole and is fixed with a pressing plate 12, the size of the pressing plate 12 is larger than the size of the sliding hole to prevent the ejector pin 13 from falling off from the sliding hole.

[0034] When the functional signal needle module 3 needs to be removed, press the button 12 to drive the ejector pin 13 to move forward, thereby pushing the elastic sheet 11 forward and squeezing the elastic sheet 11 to cause it to be misaligned with the limit platform 10. After the limit platform 10 loses its resistance, the functional signal needle module 3 can be pulled out.

[0035] According to a preferred technical solution, the elastic reset structure includes a spring 14 , which is sleeved on the ejector pin 13 , and two ends of the spring 14 are respectively connected to the pressing plate 12 and the base 1 .

[0036] The preferred technical solution is that the push plate 12 at the rear end of several ejector pins 13 is connected as an integral arrangement, the rear end of the base 1 is fixedly provided with an adjustment box 7 covering the several ejector pins 13, the integrally arranged push plate 12 matches the adjustment box 7 and is slidably arranged in the adjustment box 7, a push hole is opened at the rear end center of the adjustment box 7, a button 8 is matched in the push hole, and the button 8 is fixedly connected to the integrally arranged push plate 12.

[0037] By pressing the button 8 and pushing the integral pressing plate 12, several ejector pins 13 can be pushed forward together. The elastic sheet 11 on each functional signal pin module 3 is squeezed and dislocated with the corresponding limit platform 10, so that the functional module can be pulled out and replaced at will.

[0038] In a preferred technical solution, the limiting head 15 is spherical in shape, which reduces the sharp corners and edges on the limiting head 15 to avoid scratches on the elastic sheet 11 .
