Problems solved by technology

[0002] At present, only a multimeter can be used to detect the relay. When the number of turns of the relay coil is reduced by dozens of turns, the resistance of the relay coil does not change much, but the performance of the relay decreases. Using a multimeter cannot truly reflect the performance and quality of the relay.

Embodiment Construction

[0020] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0021] First of all, before describing the embodiments, it is necessary to explain some terms appearing in this text. E.g:

[0022] Herein, terms such as "first" and "second" may be used to describe various elements, but these elements should not be limited by these terms. These terms are only used to distinguish one element from another. Thus, a "first" element could also be termed a "second" element without departing from the teachings of the present inven...

Abstract

The invention discloses a relay performance detector, which comprises a battery, two switches, two indicating devices, two voltmeters, a relay socket, a single-chip microcomputer and a liquid crystal display; the negative pole of the battery is connected with the first contact piece of the relay socket, and the positive pole passes through two switches Afterwards, it is connected with the second contact piece, and the node between the two switches is connected with the third contact piece; the second contact piece is also directly connected with one end of a voltmeter, and the negative pole is connected with the other end of the voltmeter and the first contact piece, The fourth contact piece is connected to the negative pole through an indicating device, and the fourth contact piece is also connected to the first end of another voltmeter, and the second end is connected to the third contact piece; the fifth contact piece is connected to the battery through another indicating device. The node between the fifth contact piece and the other indicating device is also connected to the first end of the voltmeter, and the single-chip microcomputer is used to receive the voltage value measured by the two voltmeters and display it on the liquid crystal display superior. The above-mentioned relay performance detection device can truly measure the performance and quality of the relay.

Description

technical field [0001] The invention relates to a detection device, in particular to a relay performance detector. Background technique [0002] At present, only a multimeter can be used to detect relays. When the number of turns of the relay coil decreases by dozens of turns, the resistance of the relay coil does not change much, but the performance of the relay decreases. Using a multimeter cannot truly reflect the performance and quality of the relay. Contents of the invention [0003] Aiming at the deficiencies of the above-mentioned prior art, the technical problem to be solved by the present invention is to provide a detector that can actually measure the performance and quality of the relay. [0004] A relay performance detector provided by the present invention includes a storage battery, a first switch, a second switch, a first indicating device, a second indicating device, a first voltmeter, a second voltmeter, a relay socket, a single-chip microcomputer and a li...
