Embodiment Construction

[0019] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0020] Such as Figure 1 to Figure 4 As shown, the structural schematic diagrams of the front view, right view, top view and perspective view of the safety relay module tester of the present invention are provided respectively, which include a base 1, a vertical beam 2, a cross beam 3, an upper movable plate 4, and a lower bearing plate 5 , lifting arm 6, handle 7, support frame 8; the base 1 plays the role of fixing and supporting, and it can be made of bakelite material. The bakelite has the characteristics of insulation, no static electricity, wear resistance and high temperature resistance, and meets the long-term use of the tester. Require. The two vertical beams 2 are fixed on the base 1 , and the crossbeam 3 is fixed on the tops of the two vertical beams 2 . Lifting arm 6 is arranged on support frame 8, and can move up and down along support fr...

Abstract

The invention provides a safe relay module tester which comprises a mechanical structure portion and a circuit portion. The safe relay module tester is characterized in that a beam is fixed on a base through two vertical beams, a lifting arm is fixed on the beam through a supporting frame, an upper movable board is fixed at the lower end of the lifting arm, a lower bearing board is fixed on the base, a plurality of conducting probes which are matched with wiring terminals and testing points of a PCB board of a safe relay are fixed on the lower bearing board, and a plurality of pressing rods which exert pressure on the PCB board of the safe relay are fixed on the lower surface of the upper movable board. The tester can effectively and rapidly fix a safe relay module, and can rapidly and accurately achieve measurement of performance of the safe relay module. When an inferior-quality product appears, inspection personnel can be reminded of the inferior-quality product through a sound-light alarm signal, and detection efficiency of the safe relay module is effectively improved. The safe relay module tester has the advantages of being novel in structure, easy to operate, high in work efficiency and convenient to apply and popularize.

Description

technical field [0001] The invention relates to a safety relay module tester, in particular to a safety relay module tester which can quickly and accurately detect product performance. Background technique [0002] The safety relay is composed of several relays and circuits, which can complement each other's abnormal defects to achieve the complete function of the correct and low-malfunction relay, reducing the probability of failure and failure to achieve higher safety performance. The safety relay module is an emerging product. The function of the safety relay module is complex, and its detection is relatively cumbersome, resulting in low production efficiency, and it is easy to drop the detection steps, resulting in incomplete function inspection, which affects product quality. Contents of the invention [0003] In order to overcome the shortcomings of the above-mentioned technical problems, the present invention provides a safety relay module tester that can quickly a...
