Embodiment Construction

[0023] Such as figure 1 As shown, the electric meter testing fixture of the present invention includes a base 1 . A positioning groove 11 is formed on the upper surface of the base 1 for placing the printed circuit board 9 of the electric meter to be tested.

[0024] The frame 2 is installed on the base 1 . The frame 2 includes a fixed plate 20 movable up and down. Two guide rods 21 passing through the fixing plate 20 can be arranged in the frame 2 to guide the fixing plate 20, so that the movement is more stable and reliable. The probe card 22 is located under the fixing plate 20 and facing the positioning slot 11 . A plurality of probes 23 are formed in the probe card 22, and the number and distribution positions of the probes 23 are related to the number and positions of the components of the electric meter to be tested. The probe card 22 is detachably connected to the fixing plate 20 through a connecting rod 25 . When testing different printed circuit boards 9 , the p...

Abstract

The invention relates to a test tool for an electric meter. The test tool comprises a base, a framework mounted above the base, a probe board, a plurality of probes and a master control unit, wherein the base is provided with a positioning groove, and the positioning groove is used for placing a printed circuit board of the electric meter to be detected; the framework comprises a fixed board which can be moved up and down; the probe board is detachably mounted below the fixed board and can move along with the fixed board, and the probe board is dead against the space above the positioning groove; the probes are exposed from the bottom surface of the probe board, and the number and the distribution of the probes correspond to the structure of the printed circuit board of the electric meter to be detected; and the master control unit is mounted in the base, and is electrically connected with all the probes and used for receiving detection data detected by the probes. By adopting the test tool for the electric meter, all required detection items can be completed by operating once, the detection is fast and accurate, the time is greatly saved and the detection efficiency is improved.

Description

technical field [0001] The invention relates to a detection device for a printed circuit board, in particular to a testing tool for an electric meter. Background technique [0002] At present, the electric energy meter manufacturers need to detect the circuit of the printed circuit board in the process of producing electric meters. This kind of detection is usually carried out manually with multiple devices such as multimeters, clock testers, and communication equipment. The workload is heavy, the detection speed is slow, and error-prone. Moreover, during the test, the circuit board is powered on, which may cause an electric shock hazard to testers. Contents of the invention [0003] The purpose of the present invention is to provide a meter testing tool, which can quickly and accurately detect the printed circuit board of the meter while ensuring the safety of testers. [0004] In order to achieve the above object, the present invention provides an electric meter testin...
