Description

Universal probe signal adapter

technical field

The utility model relates to a circuit measuring device, in particular to an adapter seat for a universal probe signal.

Background technique

At present, there are generally two types of adapters used for universal probes. One is that a wire is welded on one end of the spring, and the other end of the spring is in contact with the probe, so that the current measured by the probe, It can be transmitted to the wire through the spring to measure the power data. However, this type of universal probe adapter uses the spring as the medium for conducting the current. Not only the impedance is high, but also the initial pressure cannot be measured when it is in contact. , so it is not easy to obtain correct test results, and the spring is easy to break and has a short service life.

Another universal probe adapter seat, a spring sleeve is placed in a tube body, and a wire is connected to the end of the spring, and the other end of the spring is in contact with the probe, so that the probe can measure The electric current can be transmitted to the wire through the spring to measure the power data. However, the above two known universal probe adapters all use springs to directly contact the probe, except that the initial contact moment cannot be measured. In addition to the pressure value, in the application, the probe often penetrates the distance between the spring coil and the coil, causing the spring to be easily deformed and broken, which also affects the measured value of the test, which greatly increases the misjudgment rate, and obviously has The need for improvement.

In view of this, the creator of the utility model researches and innovates, revealing a universal probe signal adapter.

Detailed ways

Please refer to Fig. 1 to Fig. 5, the utility model relates to a universal probe signal adapter seat, including: a pipe body 10, in its pipe wall 11, an upper limit flange 111 and a bottom Limiting flange 112; a slider 20 is slidably placed in the tube body 10, and a shoulder 21 is formed on its outer edge to lean against the upper limit flange 111 of the tube body 10 to block the The slider 20 continues to slide upward; a spring 30 is placed in the tube body 10, and its upper and lower spring ends 31, 32 are supported between the slider 20 and the lower limit flange 112 of the tube body 10; and A current output conductor 40 is connected to the bottom of the tube body 10 . In this way, when a probe 60 against the circuit board 50, such as an oblique probe, is a conventional component and is not the purpose of the utility model patent application, so it will not be described in detail, its bottom first touches the slider 20 When the top end face 22 is closed, an initial voltage can be measured on the current output conductor 40. When the probe 60 is pressed down continuously, the probe 60 can move along the top end face 22 of the slider 20 towards the pipe body 10. The wall 11 slides in the direction and contacts with the tube wall 11, so that the current of the electronic components of the circuit board 50 measured by the probe 60 can flow to the current output conductor 40 along the tube wall 11 of the tube body 10, because the tube body 10 uses Made of low-resistance conductive material such as copper, its resistance is extremely low, so a relatively accurate voltage value can be measured on the current output conductor 40, so that the false detection rate is greatly reduced.

The utility model discloses the universal probe signal adapter seat, wherein the tube body 10 can be made of metal materials such as copper, aluminum, etc., as shown in Figure 1, when assembling, the slider 20 and the spring After 30 is placed in the pipe body 10, the upper limit flange 111 and the lower limit flange 112 can be formed on the pipe wall 11 of the pipe body 10 by rolling, as shown in FIGS. 2 and 3 .

The utility model discloses the universal probe signal adapter seat, wherein the current output conductor 40 is soldered to the periphery of the tube wall 11 at the bottom of the tube body 10 with solder 41; of course, the current output conductor 40 can also be welded to the The outer edge of the pipe body 10 is not limited by the present invention.

In the application of the utility model, by means of a jig [not shown in the figure], several universal probe signal adapters shown in the utility model are linked at the same time, and several universal probes can be operated in operation. The signal adapter rises and falls together to approach the probe 60. When the top of the slider 20 of the present utility model touches the probe 60, the current of the electronic components on the circuit board detected by the probe 60, It can be transmitted to the current output conductor 40 via the slider 20, the spring 30, and the lower limit flange 112 of the tube body 10 in contact with the spring 30, so that the operator can measure the initial voltage in advance, as shown in Figure 4; When the adapter of the universal probe signal continues to exert relative pressure toward the probe 60, as shown in FIG. 11. At this time, the current measured by the probe 60 is directly transmitted to the current output conductor 40 through the tube body 10 with the smallest resistance. Therefore, the utility model can greatly reduce the mismeasured value and make the measurement more accurate .

Because the utility model contacts the probe 60 with the top end surface 22 of the slider 20, its contact area is extremely large, so it is applicable to probes 60 of different sizes, and there is no phenomenon of poor contact, which shows its novelty.
