Embodiment 1

[0029] When carrying out the vehicle static separate fuse circuit electric parameter collection of automobile fuse circuit electrical performance test, the automobile fuse 12 of the circuit under test is pulled out from the vehicle fuse box, and inserted in the fuse slot 11 on the top of the main body 9 of the electric parameter acquisition device. Then insert the fuse pin 8 at the lower end of the main body 9 of the electrical parameter acquisition device into the fuse slot of the tested circuit of the automobile fuse box, and connect the whole test device into the tested fuse circuit.

[0030] The signal transmission line 4 electrically connects the electrical parameter acquisition device 3 with the data recording and sending device 6 through the self-locking connector plug 13. The self-locking connector 13 prevents the connection point from falling off due to vibration during the test; the shunt 14 will flow through the fuse circuit. The large current is converted into a sma...

Embodiment 2

[0033] When collecting the electrical parameters of the vehicle dynamic multi-fuse circuit for the electrical performance test of the automobile fuse circuit, confirm the position of the fuse that needs to monitor the parameters, then pull out all of them and replace them with multiple electrical parameter acquisition devices 3, and connect to the data through multiple signal transmission lines 4 The recording and sending device 6 is then named in the software of the computer 7 to distinguish the name of each circuit to prevent confusion. The system connection mode is consistent with that of Embodiment 1, except that one electrical parameter collection device 3 is expanded from one to several.

[0034] When collecting the electrical parameters of the dynamic multi-fuse circuit of the vehicle, to ensure that the system starts to work, first turn on the quick switches 10 on all the electrical parameter acquisition devices 3, then start the vehicle, turn on the vehicle load as req...

Embodiment 3

[0036] When performing parameter collection after the fuse is blown in the electrical performance test of the automobile fuse circuit, confirm the position of the fuse that needs to monitor the parameters, then pull out all of them and replace them with multiple electrical parameter collection devices 3, and connect to the data recorder and the data recorder through multiple signal transmission lines 4 The sending device 6 is then named in the software of the computer 7 to distinguish the name of each circuit to prevent confusion. The system connection mode is consistent with that of Embodiment 1, except that one electrical parameter collection device 3 is expanded from one to several.

[0037] When carrying out the parameter acquisition after the fuse of the vehicle is blown, ensure that the system starts to work, first connect the quick switch 10 on all electrical parameter acquisition devices 3, turn on the vehicle load as required, and then cut off the circuit that needs to...

Abstract

The invention provides an automobile fuse loop electrical performance testing device and a system thereof. The automobile fuse loop electrical performance testing device comprises an electrical parameter acquisition device body. The bottom of the electric parameter acquisition device body is provided with a fuse pin for inserting the electrical parameter acquisition device into a fuse slot of theautomobile. The top of the electrical parameter acquisition device body is provided with a fuse slot for inserting the fuse which is pulled out of the automobile into the electrical parameter acquisition device body for recovering the whole fuse loop. One side of the electrical parameter acquisition device body is provided with a quick switch for switching on or switching off the whole fuse loop.The other side of the electrical parameter acquisition device body is provided with a current divider which is connected with a self locking device. The automobile fuse loop electrical performance testing device has advantages of simple mounting, simple detachment, high speed, high convenience, no influence to actual electrical characteristic, simultaneous acquisition of current and voltage, concise line harness, omission of an external current sensor, high precision and high accuracy in data acquisition, high safety and high reliability.

Description

technical field [0001] The invention belongs to the technical field of automobile electrical testing, and in particular relates to an electrical performance testing device and system of an automobile fuse circuit. Background technique [0002] At present, due to the continuous improvement of vehicle functions, the load of automotive electrical appliances is increasing, and the electrical circuits are becoming more and more complex. The complicated electrical circuits also cause problems in various electrical systems of the vehicle. In order to solve these problems, automotive electrical testing must indispensable. As the protection device of each wiring harness circuit, the fuse plays an important role in protecting the circuit harness and load, and the fuse is also the starting point of each electrical circuit. Therefore, by collecting the electrical parameters of the stable operation of the entire circuit at the automobile fuse, and conducting fuse blown, short circuit, a...
