Detailed Description
The following provides a more detailed description of the present invention with reference to the accompanying drawings and detailed description.
As shown in figures 1, 2, 3, 4, a small-size single-phase electric energy meter, including table box 1, set up the circuit board in the table box and be used for connecting the incoming line box 2 and the outlet box 3 of business turn over line, the incoming line box all is located the same one end of table box with the outlet box, and incoming line box and outlet box electrical isolation, and the incoming line box overlaps from top to bottom with the outlet box and establishes and the ladder setting. The inlet box and the outlet box body are integrally arranged.
The wire inlet box and the wire outlet box are respectively provided with a wiring hole 9, a relay 10 is connected between the wire inlet box and the wire outlet box, a conductive copper bar 8 is directly led out from the relay, and the conductive copper bar is inserted and connected into the corresponding wiring hole 9. The circuit board includes first circuit board 5, second circuit board 7, and first circuit board, second circuit board set up side by side relatively, set up contact pin 4 on the first circuit board, set up socket 6 on the second circuit board, and first circuit board, second circuit board insert through the contact pin and realize the electricity connection in the socket. The meter box 1 comprises a base and a cover plate 9, welding ribs 10 are arranged on the edges of the base and the cover plate, and the cover plate is fixed on the base in an ultrasonic welding mode. And the welding muscle that is located on the base border is complementary with the position that is located both welding muscle on the apron border and sets up, sets up the position of welding muscle promptly on the base border, and then needn't set up the welding muscle again on the corresponding position of apron, and is corresponding, sets up the welding muscle position on the apron, does not set up the welding muscle on the base position that corresponds, and both complementary settings, then during ultrasonic bonding, the leakproofness is better.
