Problems solved by technology

However, this connection method lacks the positioning and fixing of the relay, the connection between the alligator clip and the relay terminal is unstable, and affected by the structure of the alligator clip itself, the alligator clip may damage the surface of the terminal
In addition, this connection method can only detect one relay at a time, and the detection efficiency is relatively low

Abstract

The invention provides a relay positioning test device and relay test equipment using the same. The relay positioning test device comprises: a base, wherein the base is provided with at least one group of probes, each group of probes comprises two probes, and each probe is provided with a connecting part electrically connected with an access terminal of test equipment and a contact head contactedand electrically connected with a relay terminal; a relay positioning plate which is supported and arranged above the base through an elastic piece, wherein at least one positioning groove is formed in the relay positioning plate, and a through hole for the contact heads of the group of probes to penetrate through is formed in the bottom of the positioning groove; and an upper pressing plate whichis mounted on the base in an up-and-down moving manner and is used for pressing the relay on the relay positioning plate when moving downwards, so that the relay positioning plate compresses the elastic piece to move downwards, and the relay terminal is in close contact with the contact head of the probe. The beneficial effects are that relay positioning is realized, connection between the relayterminal and the test equipment is realized, and relay performance detection is facilitated.

Description

technical field [0001] The invention relates to a relay positioning testing device and relay testing equipment using the device. Background technique [0002] The relay is an indispensable component in the electric energy meter circuit. A relay in the prior art is as Image 6 As shown, the relay is provided with two terminals 41, and each terminal 41 is provided with a connection hole 42 for connecting with a load. Since the relay plays an important role in protecting the circuit and switching the power supply in the entire circuit, the performance quality of the relay directly determines the quality of the electric energy meter, so it is necessary to use testing equipment to test the performance parameters of the relay. [0003] The Chinese utility model patent with the authorized announcement number CN202903969U discloses a relay low-level detection device, including a transformer device, a load, and an operating device. The operating device includes a test piece access te...
