Background

With the development of industrial electronic technology, circuit boards are used in a large amount in the field of electronic machinery, the progress of modern civilization is promoted by the large amount of use of the circuit boards, and the development process of industrial automation is improved. In the process, the test work of the circuit board is valued by various production enterprises. In the prior art, a test pen of a test device such as an oscilloscope, a universal meter and the like is usually directly used to directly contact each test point on a circuit board, or a connection line is welded to each test point of the circuit board to measure and obtain various required index parameters on the circuit board, and the quality and the qualification of the circuit board are judged through such measurement data. The debugging and testing method has the defects of low debugging and testing efficiency, wrong measured test point position and the like. The circuit board is a key component of various devices, and the quality of the circuit board usually directly affects the safe and stable operation of the devices.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a quick test frame of circuit board.

The utility model discloses an innovation point lies in the utility model discloses well circuit board test convenient and fast, dismantle the convenience.

In order to realize the purpose of the utility model, the technical proposal of the utility model is that: a circuit board rapid test frame comprises a test substrate, wherein a plurality of test probes are arranged on the test substrate, a plurality of test leading-out points are arranged at the edge of the test substrate, each test probe is connected with one test leading-out point through a printing line, and a plurality of fixing columns for fixing a circuit board are arranged on the test probes.

Furthermore, an elastic bulge component is arranged on the fixing column. The circuit board is provided with a copper sleeve sleeved on the fixing part, and after the elastic bulge part is arranged, the elastic bulge part is clamped in the copper sleeve, so that the circuit board can be prevented from being jacked up by the test probe.

Furthermore, a connecting fixed seat is arranged on the bottom surface of the test substrate, a plurality of connecting columns are arranged on the top surface of the connecting fixed seat, threaded inserted rods with diameters smaller than the connecting columns are arranged at the upper ends of the connecting columns, inserting holes for inserting the threaded inserted rods are formed in the test substrate, the diameters of the inserting holes are smaller than the diameters of the connecting columns, and the test substrate is fixed by screwing the threaded inserted rods through nuts after being sleeved in the threaded inserted rods; the base is arranged at the bottom of the connecting fixed seat, and the connecting fixed seat is connected with one side of the base through a hinge. The connecting fixing seat can be turned over relative to the base, so that the front side and the back side of the tested and debugged circuit board can be debugged by using tools.

Furthermore, a plurality of notches are formed in the connecting and fixing seat, and a plurality of through holes are formed in the positions, corresponding to the notches, of the test substrate. The debugging tool is convenient to insert into the debugging position of the tested circuit board.

Furthermore, a test hook is welded on the test leading-out point. The connection of the test instrument is convenient.

The utility model has the advantages that:

1. the utility model discloses well circuit board test convenient and fast, dismantlement convenience only need insert the copper sheathing on the circuit board on the fixed column, can communicate test point and test probe on the circuit board then, communicate the test draw-off point, survey at test draw-off point department and connect test equipment, convenient and fast directly extracts the copper sheathing from the fixed column when taking away can.

2. The utility model discloses in still make things convenient for the reverse side of test circuit board, it can to connect the fixing base upset.
