[0036] The specific structure of external frame body 1 is as shown in Figure 1 、 Figure 6 , the chute 2 is through the top wall and the bottom wall of external frame body 1, the side wall of installing slide 11 and adjusting bolt 12 is front side wall, and the rear side wall is provided with the through slot for the elastic terminal connecting piece 4 to pass out.Connecting box 3 is used to install elastic terminal connecting piece 4;Elastic terminal connecting piece 4 is used to connect with the three-phase connection terminal of three-phase electric energy meter;Power supply interface 5 is used to provide voltage for testing.

[0037] The existing three-phase electric energy meter is divided into A, B and C, and each is divided into one in and one out, and at least two bolts are needed to connect with the aging seat during detection.Elastic terminal connecting piece 4 is 6 in the present application, which is because each item of three-phase electric energy meter is divided into one in and one out, so that the six elastic terminal connecting pieces 4 are just matched with them, and if two-phase electric energy meter needs to be compatible, the number of corresponding elastic terminal connecting pieces 4 can be adjusted.

[0038] By setting elastic terminal connecting piece 4, the aging seat and three-phase electric energy meter realize plug-in connection, without repeatedly disassembling and fastening screw, only need to insert the electric energy meter into the elastic terminal connecting piece 4 to complete the wiring, greatly reduce the manual operation steps, significantly improve the aging test efficiency, reduce the labor cost.And, the traditional way needs to be tightened and loosened several times, which is easy to cause screw slipping or electric energy meter interface damage, and the present application automatically crimps the elastic terminal, avoids mechanical wear and tear, and improves the service life of test equipment and electric energy meter.

[0039] When using, the three-phase connection terminal of three-phase electric energy meter is inserted into the corresponding elastic terminal connecting piece 4, and the three-phase electric energy meter is fixed in position through external fixing device, and the power supply interface 5 can be connected through the wire.

[0040] As shown in Figure 3 、 Figure 4As shown, the elastic terminal connector 4 includes a sliding cavity 41, a conductive connector 42, a wiring connector 43, and a compression spring 44. The sliding cavity 41 is opened inside the connection box 3, the conductive connector 42 is slidably connected in the sliding cavity 41, the wiring connector 43 is installed on the top of the conductive connector 42 and passes through the sliding cavity 41. The wiring connector 43 can enter the sliding cavity 41.

Preferably, a threaded hole 421 for wiring is opened through the end of the conductive connector 42.

[0041] In this embodiment, the internal structure of the connection box 3 is as follows: Figure 3 As shown, the connection box 3 is divided into two half shells, which are buckled together and fixed by bolts to form the connection box 3. A sliding cavity 41 is opened inside the connection box 3 and extends to the side wall of the connection box 3 to form an opening. One end of the conductive connector 42 is slidably connected to the sliding cavity 41, and the other end passes through the external frame 1. The conductive connector 42 can provide a load, and through the threaded hole 421 on the conductive connector 42 and the wire, multiple sets of the simple aging sockets of the three-phase electric energy meter of the present application are connected.

[0042] The bottom of the wiring connector 43 is formed with a threaded column, which passes through the conductive connector 42 and is fixedly connected to the conductive connector 42 by a bolt. The setting position of the compression spring 44 is as follows Figure 3 As shown, compression spring 44 provides an upward thrust, pushing conductive connector 42 and wiring connector 43 upward.

The arc portion 431 is designed to fit snugly within the bolts within the three-phase terminal blocks, ensuring a tighter connection and improved electrical conductivity. Therefore, the arc portion 431 is designed to match the bolts within the three-phase terminal blocks.
