Abstract

The invention relates to a device for testing the durability of an automobile relay, which comprises a control unit, an auxiliary relay driving unit, an auxiliary relay, a testing relay driving unit, a testing relay, auxiliary loads, a current detecting unit and an inputting and displaying unit, wherein the control unit is used for judging various input signals and controlling various output signals; the auxiliary relay driving unit is used for controlling the on or off of the auxiliary relay; the two ends of the auxiliary relay are connected with auxiliary loads in parallel; the testing relay driving unit is used for controlling the on or off of the testing relay; the testing relay is connected with a working load in series; the auxiliary loads and the working load are mutually matched to provide impulse current and stationary working current for the contact circuit of the testing relay; the current detecting unit is used for detecting the current of the contact circuit of the testing relay; and the inputting and displaying unit is used for inputting various testing parameters and displaying various parameters. The testing method provided by the invention comprises the following steps of: providing impulse load current and stationary load current for a relay; and starting to stop circulation control and count the circulation times, thereby testing the durability of the automobile relay.

Description

technical field [0001] The invention relates to the field of relay durability testing, in particular to an automobile relay durability testing device and method. Background technique [0002] The relay is an automatic control device whose output changes in a jump when the input quantity (electricity, magnetism, sound, light, heat) reaches a certain value. It is usually used in automatic control circuits. It actually uses a small It is an "automatic switch" that controls the large current, so it plays the role of automatic adjustment, safety protection, conversion circuit, etc. in the circuit. Relays can be divided into communication relays, machine tool relays, home appliance relays and automotive relays according to their uses. Among them, the automotive relay is the relay used in the car. This type of relay has high switching load power and high shock resistance and vibration resistance. The durability of the same automotive relay is different under different inrush curr...
