Summary of the invention
For addressing the above problem, the utility model provides a kind of easy to use, test accurately, can detect the ICT measurement jig of polar capacitor polarity.
The utility model for the technical scheme that its problem of solution adopts is:
A kind of ICT measurement jig that can detect polar capacitor polarity, comprise base and be arranged on the pneumatic shuttle of base top, described base is provided with the support plate for placing circuit board, and on base, being also provided with can be through support plate the probe contacting with the pin of polar capacitor on circuit board; Described pneumatic shuttle is provided with removable and compresses the pressing plate of circuit board, the bottom surface of described pressing plate is provided with some inductive needles that contact and carry out signal contact with the end face of polar capacitor on circuit board, described inductive needle can contact with polar capacitor with probe simultaneously, and signal is detected.
Preferably, described support plate bottom surface is provided with elastic device.
Preferably, the bottom surface of described pressing plate is provided with for circuit board being pressed on to the depression bar on base.
Preferably, also comprise the upper plate being connected with pneumatic shuttle, pressing plate is arranged on the bottom surface of upper plate.Further, between described upper plate and pressing plate, being provided with thumbscrew is connected.
The beneficial effects of the utility model are: product is easy to use, test accurately, after operator is placed on circuit board to position on support plate, startup system, pneumatic shuttle drives pressing plate to move down, pressing plate compresses circuit board, the pin of the polar capacitor on circuit board is contacted with probe, and be electrically connected, simultaneously, inductive needle contacts with the top of polar capacitor, be electrically connected, alternately forming loop with two pins respectively by inductive needle is electrically connected, detect, avoid because polar capacitor both positive and negative polarity is reverse, thereby cause polar capacitor to damage or quality problem related to this.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail:
Fig. 1 is structural representation of the present utility model.
Wherein: 1, base, 2, pneumatic shuttle, 3, support plate, 4, pressing plate, 5, inductive needle, 6, probe, 7, polar capacitor, 8, circuit board, 9, spring part, 10, depression bar, 11, upper plate, 12, thumbscrew.
Embodiment
A kind of ICT measurement jig that can detect polar capacitor polarity as shown in Figure 1, comprise base 1 and be arranged on the pneumatic shuttle 2 of base 1 top, described base 1 is provided with the support plate 3 for placing circuit board 8, is also provided with and can carries out the probe 6 that signal contacts through support plate 3 and with the pin of polar capacitor 7 on insertion circuit board 8 on base 1.The front of base 1 can setting operation button, for example, start the button of pneumatic shuttle 2 rise and fall, or replacement button.
Described pneumatic shuttle 2 is provided with removable and compresses the pressing plate 4 of circuit board 8, the bottom surface of described pressing plate 4 is provided with some inductive needles 5 that contact and carry out signal contact with the end face of polar capacitor 7 on circuit board 8, the setting of inductive needle 5 should with the matched of polar capacitor 7, avoid oversize and pierce through polar capacitor 7, or too shortly cause loose contact.Polar capacitor 7 also should be ajusted as far as possible simultaneously, avoids crooked, causes loose contact.
By accompanying drawing, operating process of the present utility model and detection principle are further described below.After operator is placed on circuit board 8 to position on support plate 3, startup system, pneumatic shuttle 2 drives pressing plate 4 to move down, pressing plate 4 compresses circuit board 8, the pin of the polar capacitor 7 on circuit board 8 is contacted with probe 6, and be electrically connected, simultaneously, inductive needle 5 contacts with the top of polar capacitor 7, is electrically connected, and alternately forms loop be respectively electrically connected by inductive needle 5 with two pins, complete detection, avoid, because the both positive and negative polarity of polar capacitor 7 is anti-inserted, detecting, and causing polar capacitor 7 to damage.
Wherein, described support plate 3 bottom surface one sides are provided with elastic device, and described elastic device can be spring part 9, in the time that pressing plate 4 is pressed downwardly onto support plate 3, has certain impulse force, can effectively alleviate this impulse force by spring part 9, avoids circuit board 8 to be impacted and damages.
In addition, the bottom surface of described pressing plate 4 is provided with for circuit board 8 being pressed on to the depression bar 10 on base 1, and because circuit board 8 is provided with polar capacitor 7, the position distribution of depression bar 10 should be passed through certain design, while avoiding depression bar 10 to be pressed on circuit board 8, damage polar capacitor 7.Meanwhile, depression bar 10 distributes and wants evenly, makes to be applied to pressure on circuit board 8 even, and circuit board 8 maintenance levels can not tilt, and guarantee that probe 6 contacts well with polar capacitor 7 with inductive needle 5.According to the difference of the circuit board 8 of test, operating personnel can change the depression bar 10 of different size.
