Abstract

The utility model relates to a safe and reliable PCBA (printed circuit board assembly) test device. The test device comprises a control cabinet, a needle bed and a compressing assembly. The needle bed is encapsulated at an opening of the upper end of the control cabinet. A plurality of probes are vertically fixedly arranged on the needle bed. Positioning rods for positioning a PCBA are mounted on the needle bed on two sides of the probes. The PCBA is compressed downwardly by the compressing assembly, so that contacts on the lower end face of the PCBA are contacted with the probes. A safe switch for controlling the connection and disconnection of the probes is mounted on the needle bed corresponding to the lower end of the compressing assembly. According to the PCBA test device of the utility model, the safe switch for controlling the connection and disconnection of the probes is mounted on the needle bed, so that the safety of the test device is effectively improved; and the PCBA can be quickly positioned on the needle bed by the positioning rods and stopper columns, and the contacts on the lower end face of the PCBA are contacted with the probes by the compressing assembly, thereby achieving the detection of the PCBA with high speed, safety and accuracy.

Fig. 2 is I portion enlarged drawing in Fig. 1;

Fig. 3 is the utility model left view;

Fig. 4 is the utility model needle-bar structural representation.

Embodiment

Below in conjunction with accompanying drawing and by specific embodiment, the utility model is described in further detail.

A kind of safe and reliable PCBA board test apparatus, as shown in Figures 1 to 3, comprise control box 9, needle-bar 8, hold down assembly, described control box is the casing of a rectangular configuration, its upper end open place is packaged with needle-bar, on this needle-bar, be vertically fixed with a plurality of probes 10, on the needle-bar of these probe both sides, be provided with for locating the backstay 7 of PCBA plate, by holding down assembly, compress PCBA plate downwards, thereby the contact of PCBA plate lower surface is contacted with probe, circuit communication in this probe and control box, thus realize the object of testing.

Innovative point of the present utility model is:

The safety switch 13 of one control probe break-make is installed on the needle-bar of the bottom that holds down assembly described in correspondence, as shown in Figure 3, thereby move down touching safety switch by holding down assembly, probe is switched on, this safety switch effective security performance that improves testing apparatus is set.

Described holding down assembly comprises bracing frame 1, pressing plate 3, interlock depression bar 2 and guidepost 5; support frame as described above is a handstand " recessed " character form structure and is vertically packed on the needle-bar of probe rear side; on the needle-bar of this bracing frame breach below and corresponding described probe by guidepost, be slidably fitted with pressing plate; this pressing plate is controlled it and is moved up and down by being arranged on interlock depression bar on bracing frame; the lower surface of this pressing plate is provided with a lower lock block 4; it is to make part components and parts pressurized that this lower lock block arranges object, protects the irregular or components and parts of not to be stowed under heavy cargo of other profiles.

The structure of described needle-bar as shown in Figure 4, the bottom of described backstay is provided with back-moving spring 12 as shown in Figure 2, thereby can realize moving up and down of support column, the both sides of described each backstay are vertically provided with respectively limited post 6, limited post in the present embodiment is eight, and the outside of described control box is provided with power switch 11.
