To the problem that exists among the prior art, the utility model provides a vehicle-mounted high definition audio and video line can detect whether the circuit that the contact pin corresponds is qualified, improves the product percent of pass.
In order to solve the technical problem, the technical scheme of the utility model as follows: the utility model provides a measure on-vehicle high definition audio frequency and video line detecting instrument, includes the box body, its characterized in that: the box body is inside to be equipped with the multiunit and to detect the circuit, and the multiunit detects the circuit and is connected with the power through parallelly connected mode, and every group detects the circuit and all includes test connector, contact switch, shunt resistor, signal lamp, and test connector, shunt resistor, contact switch, signal lamp electricity in proper order are connected.
The improvement of the technical scheme is as follows: a plurality of operating buttons are evenly distributed on the box cover of the box body, the number of the operating buttons is consistent with that of the detection lines, and the operating buttons correspond to the contact switches of the detection lines.
The technical scheme is further improved as follows: and one side of the box body is provided with a switch button, and the switch button is connected with a power supply.
The technical scheme is further improved: the test joints extend from the sides of the box body.
Has the advantages that:
use an on-vehicle high definition audio frequency and video line, through the demonstration of different detection circuitry and signal lamp, whether can be simple, convenient differentiation circuit is the correct configuration, effectively improved the rate of accuracy that detects, improved the qualification rate of product.
