Embodiment 1

[0025] Such as figure 1 As shown, a test probe device 100 is composed of a needle holder main body 1, a test needle 20, a plastic spring bracket 3 and a pressure sensor 4, wherein the needle holder main body is composed of a fixing seat 10, a test needle fixing seat 11, and a U-shaped pressure adjustment 12 and a pressure sensor fixture 13, the test needle 20 includes a knife-shaped test probe 2 and a signal output line 22 connected to the test probe, the signal output line 22 is connected to the fixing seat 10 at the rear end of the main body; the test needle 20 is fixed on On the plastic spring support 3, the plastic spring support 3 is fixed on the front end of the needle seat main body 1 through the test needle holder 11; the pressure sensor 4 includes a pressure sensor main body 40, a pressure data transmission line 41 and a pressure data transmission line connector 42, the pressure sensor main body 40 is fixed on the upper surface of the needle holder main body 1 through...

Embodiment 2

[0031] The difference between this embodiment and the previous example is:

[0032] Such as figure 2 As shown, the test pin 20 includes two parallel upper and lower test pins 20a, 20b, the upper and lower test pins 20a, 20b are knife-type test probe test pins, and the opposite surfaces of the two knife-type test probes 2a, 2b are connected to each other. Insulation. The plastic spring support 3a of the upper test needle is fixed on the fixed seat 10 at the front end of the needle holder, and the upper test needle holder 11a combines the plastic spring support 3b of the lower test needle with the plastic spring support 3a of the upper test needle. The signal output lines 22 on the two knife-type test probes 2a, 2b are respectively led to the rear end sampling points of the needle sockets for current and voltage sampling respectively.

Description

technical field [0001] The invention relates to a printed circuit board (PCB) test device, in particular to a test probe device. Background technique [0002] Existing test probe mainly has three parts to form: the one, needle tube: mainly take copper alloy as the gold-plated outside of material. The second is the spring: mainly the piano steel wire and the spring steel are plated with gold. The third is the needle head: mainly tool steel (SK) nickel-plated or gold-plated. The above three parts are assembled into a probe. During the test process, it is easy to leave pits on the printed circuit board, which affects the quality of the printed circuit board. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned existing test probe devices, and provide a test probe device that can control the pressure of the test points of the printed circuit board and does not leave pits on the printed circuit board. ...
