BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a voltage measuring probe device, and more particularly, to a voltage measuring probe device which is mainly used for measuring a voltage between a wire and a connection terminal which is crimped and fixed thereto.

As shown in FIGS. 1 to 3, the electric wire 10 is composed of a conductor wire 11 and an insulator sheath 12 surrounding the wire 11, and at the tip of the wire 11 for electrical contact. It is common for the connection terminals 20 and 30 to be installed.

The connecting terminals 20 and 30 are divided into a female connecting terminal 20 and a male connecting terminal 30, and these connecting terminals 20 and 30 are those having a structure as shown in FIGS. Representative.

As shown in FIGS. 1 and 2, the female connection terminal 20 includes a cover fixing part 21 that is crimped and fixedly wrapped around the sheath 12 of the wire 10 and exposed to the outside of the sheath 12. The wire fixing part 22 wraps around the tip of the wire 11 and is crimped and fixed, and the protrusion insertion part 23 is detachably inserted and fixed to the connecting protrusion 33 of the male connection terminal 30.

As shown in FIGS. 1 and 3, the male connection terminal 30 includes a cover fixing part 31 which is crimped and fixed to surround the sheath 12 of the wire 10, and is exposed to the outside of the sheath 12. The wire fixing part 22 wraps around the tip of the wire 11 and is crimped and fixed, and the protrusion inserting part 23 is inserted into the protrusion inserting part 23 of the female connection terminal 20 to be detachably crimped and fixed.

Since the voltage changes according to the crimping force between the wire wire 11 and the wire fixing parts 22 and 32, the wire wire 11 and the wire fixing parts 22 and 32 in order to maintain the voltage change of the power supply within an appropriate range. The compression force of the liver should be maintained in the proper pressure range.

In addition, the operation of crimping and fixing the cover fixing parts 21 and 31 to the wire sheath 12 or the crimping and fixing of the wire fixing parts 22 and 32 to the wire wire 11 is not only simple but also easy to work. Consistency is required.

Therefore, the work of crimping and fixing the cover fixing parts 21 and 31 to the wire sheath 12 or the crimping and fixing of the wire fixing parts 22 and 32 to the electric wire 11 are consistent in work and work speed. In order to improve the performance, a separate dedicated crimping equipment is used to perform the automatic operation.

On the other hand, the voltage change measurement operation by the crimping force between the wire wire 11 and the wire fixing portion (22; 32) will be described as follows.

If the measured voltage between "P1" to "P2", or "P1" to "P3" exceeds the set voltage, the pressing force between the wire wire 11 and the wire fixing parts 22 and 32 should be lowered. If the measured voltage between "P1" and "P2" or "P1" and "P3" is less than the set voltage, the crimping force between the wire wire 11 and the wire fixing parts 22 and 32 should be increased.

However, in the related art, the operator has to hold the measuring terminal handle of the voltage measuring device in both hands to directly contact the measuring terminal with the measuring point P1 (P2, P3), so that the measuring terminal and the measuring point P1 (P2, P3) Not only is the contact area different each time, but also the contact pressure between the measuring terminal and the measuring point P1 (P2, P3) is different every time, so that the error range of the measuring voltage is expanded and the reliability of the measured voltage is greatly increased by the skill of the operator.
