Embodiment Construction
[0026] Such as figure 1 As shown, the special fixture for embedded electric energy meter testing disclosed in this embodiment includes base plate 1, guide positioning frame 2, meter locking mechanism assembly 3, main terminal test pin 4, main seat 5, auxiliary terminal A test pin 6A, a PCB board 6, and a fixing post 7.
[0027] combine figure 1 and image 3 It can be seen that the positioning guide frame 2 is a rectangular frame surrounded by four L-shaped components 21 , and the lower end of each L-shaped component 21 is respectively provided with three connecting lugs 22 .
[0028] From Figure 4 It can be seen that the watch locking mechanism assembly 3 includes a lock hook 31 , a lock hook seat 32 , an elastic handle 33 , a lock plate 34 , a connecting rod 35 , a support column 36 , a curved handle bar 37 and a spherical handle 38 . The cross-sectional shape of the support columns 36 is rectangular, and there are two in number, which are made of aluminum profiles. The...

The invention discloses a special fixture for embedded electric energy meter tests. The special fixture comprises a pedestal bottom plate, a guide positioning frame, a meter locking mechanism assembly, main terminal testing pins and mounting bases thereof, auxiliary terminal testing pins and a PCB used for mounting the auxiliary terminal testing pins. The guide positioning frame and the meter locking mechanism assembly are mounted on the upper side of the pedestal bottom plate, the main terminal testing pin mounting bases and the PCB are mounted on the lower side of the pedestal bottom plate, the main terminal testing pins and the auxiliary terminal testing pins pass through the pedestal bottom plate and are exposed thereon, a meter to be tested is placed into the guide positioning frame and is locked by means of the meter locking mechanism assembly, and the testing pins are butted with wiring terminals of the meter to be tested. According to the special fixture, the embedded electric energy meter and the assembly parts of the fixture are mounted in a bottom box of a conventional three-phase meter, all wires are connected on the corresponding main terminals and auxiliary terminals of a terminal box of the three-phase meter, so as to conform to the wiring method of a conventional electric meter, and the three-phase meter bottom box equipped with the special fixture and the terminal box of the three-phase meter is assembled on a conventional electric energy meter detecting device for detection.
Description
technical field [0001] The invention relates to a test fixture for an electric energy meter, in particular to a special fixture for testing an embedded electric energy meter. Background technique [0002] The structure of the embedded electric energy meter is different from that of the conventional electric energy meter. It is small in size and multi-functional, especially with many auxiliary interface terminals. At present, there is no special test device for the embedded electric energy meter, and the test can only be completed by using the test device of the conventional electric energy meter and connecting the wiring. [0003] In the process of production testing, the operation of switching wiring consumes a lot of time. During mass production, the operation of wiring seriously restricts the efficiency of production, and there are also hidden dangers of insecurity. Contents of the invention [0004] The main purpose of the present invention is to provide a special fi...
