Embodiment Construction

[0038] Below, the present invention will be further described in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of not conflicting, the various embodiments described below or the technical features can be combined arbitrarily to form new embodiments. .

[0039] Such as figure 1 with figure 2 As shown, this embodiment provides a detector for a relay and a driver chip, including an oscillation module, a relay socket, a contact detection module, a driver chip socket, a detection relay, a first prompt module and a second prompt module;

[0040] The oscillating module is electrically connected to the relay socket and the driver chip socket, and the oscillating module is used to generate periodic pulse signals to trigger the operation of the relay to be detected installed at the relay socket and / or trigger the operation of the relay installed at the driver chip socket. The driver chip to be detected works...

Abstract

The invention discloses a detector for a relay and a driving chip. The detector comprises an oscillation module, a relay socket, a contact detection module, a driving chip socket, a detection relay, afirst prompt module and a second prompt module. The oscillation module is electrically connected with the relay socket and the driving chip socket and is used for generating periodic pulse signals soas to trigger a to-be-detected relay installed at the relay socket to work and / or trigger a to-be-detected driving chip installed at the driving chip socket to work. According to the invention, independent detection of the performance of the relay and the performance of the driving chip as well as parallel detection of the relay and the driving chip can be realized; and dynamic detection insteadof static detection is carried out on the driving chip and thus the user can conveniently detect the actual performance of the relay and / or the driving chip.

Description

technical field [0001] The invention relates to the technical field of detection, in particular to a detector for a relay and a drive chip. Background technique [0002] Relays and driver chips are common components. Relays used in test equipment require fast response and low contact resistance (within 0.3 ohms). The aging of the relay and the deterioration of the load performance of the driver chip are the most important factors leading to the instability of the test equipment. [0003] At present, the following scheme is disclosed: the scheme with the application number CN201510525411.7, which discloses the relay action time detection circuit and detection method, because the programmable logic device also includes detection of relay normally open or normally closed contact action level state change The program and the program of the recording time length, when it is detected that the relay contact changes from one level state to another level state, the recording time is...
