Detailed Description
Embodiments of the present invention are described in detail below, and the embodiments described with reference to the drawings are exemplary.
A multimeter pen according to an embodiment of the invention is described below with reference to fig. 1. The multimeter pen can be applied to a multimeter for measuring the resistance of an object to be measured, such as the edge of a solar cell, and the like. In the following description of the present application, the application of the multimeter pen 100 to a multimeter is illustrated.
As shown in fig. 1, a multimeter pen 100 according to an embodiment of the present invention comprises a pen body 1, a first insulating member 2, a second insulating member 3, and a conductive member 4.
Specifically, the first insulating part 2 is fixedly connected to the pen body 1, the second insulating part 3 is arranged on the pen body 1, the second insulating part 3 can relatively approach and depart from the first insulating part 2 along the axial direction of the pen body 1, the conductive part 4 is arranged between the first insulating part 2 and the second insulating part 3, and the conductive part 4 is perpendicular to the central axis of the pen body 1.
For example, in the example of fig. 1, the first insulator 2 is fixed to the pen body 1, and at this time, the first insulator 2 is fixed with respect to the pen body 1, and the first insulator 2 and both end portions of the pen body 1 are spaced apart from each other. The second insulating part 3 is sleeved on the pen body 1, and the second insulating part 3 can move left and right along the axial direction of the pen body 1 to adjust the distance between the second insulating part 3 and the first insulating part 2, so that the multimeter pen 100 can effectively measure the resistance of the measured object with different thicknesses, such as the edge of a solar cell, and the universality of the multimeter pen 100 is improved. The conductive piece 4 is located between the first insulating piece 2 and the second insulating piece 3, and the conductive piece 4 is perpendicular to the central axis of the pen body 1, so that the conductive piece 4 can be effectively guaranteed to be perpendicular to the side surface of the to-be-measured surface of the measured object, such as the edge of a solar cell, all the time, and the accuracy of data measurement is improved.
When measuring the resistance of the edge of an object to be measured, such as a solar cell, the edge of the solar cell can be clamped by the first insulating part 2 and the second insulating part 3 by adjusting the position of the second insulating part 3 relative to the first insulating part 2, and because the conductive part 4 is positioned between the first insulating part 2 and the second insulating part 3 and the conductive part 4 is perpendicular to the pen body 1, the conductive part 4 can be effectively ensured to be always perpendicular to the side surface of the edge of the solar cell and not to incline to any side, the accuracy of measured data is effectively ensured, and the data fluctuation is not large during each measurement, the repeatability is good, and the operation is convenient.
According to the utility model discloses multimeter pen 100 is through setting up conductive piece 4 between first insulating part 2 and second insulating part 3 to make conductive piece 4 perpendicular with the central axis of handwriting 1, and second insulating part 3 can be close to relatively and keep away from first insulating part 2 along the axial of handwriting 1, has improved data measurement's accuracy, has reduced the fluctuation between the measured data many times, and convenient operation.
According to some embodiments of the present invention, referring to fig. 1, the first insulating member 2 and the second insulating member 3 each include an installation portion 31 and a clamping portion 32, the installation portion 31 is provided on the pen body 1, the clamping portion 32 is connected to the installation portion 31, and the clamping portion 32 extends to the outer surface beyond the conductive member 4 toward the direction away from the central axis of the pen body 1. The first insulator 2 and the second insulator 3 are adapted to be mounted on the pen body 1 through the mounting portion 31, for example, the mounting portion 31 may be sleeved on the pen body 1, and the two holding portions 32 of the first insulator 2 and the second insulator 3 are adapted to be in contact with both side surfaces in the thickness direction of the edge of the solar cell to hold the edge of the solar cell. So set up, first insulating part 2 and second insulating part 3's simple structure, processing is convenient, and is with low costs. Optionally, the clamping portion 32 and the mounting portion 31 are integrally formed, so that the processing is convenient, the manufacturing processes are reduced, and the cost is reduced.
Wherein, the clamping portion 32 can extend outwards along a direction perpendicular to the central axis of the pen body 1, and one side surface (e.g. the lower surface in fig. 1) of the clamping portion 32 far away from the central axis of the pen body 1 protrudes out of one side surface (e.g. the lower surface in fig. 1) of the conductive member 4 far away from the central axis of the pen body 1, so as to ensure that the clamping portions 32 of the first insulating member 2 and the second insulating member 3 can effectively clamp the edge of a measured object, such as a solar battery, during measurement. Here, it should be noted that the direction "outer" is understood to be a direction away from the central axis of the pen body 1, and the opposite direction is defined as "inner".
Further, as shown in fig. 1, a holding portion 32 is provided at an end of the mounting portion 31 away from the conductive member 4 in the axial direction of the pen body 1. For example, in the example of fig. 1, the clamping portion 32 of the first insulator 2 is located at the left end of the mounting portion 31, and the clamping portion 32 of the second insulator 3 is located at the right end of the mounting portion 31. Therefore, the measured object with the thickness larger than that of the conductive piece 4, such as the solar cell, can be accurately measured, and the PN junction or the high-low junction is not touched in the measuring process, so that the edge resistance of the solar cell, such as a double-sided cell, can be accurately monitored. Moreover, when measuring the edge of a relatively thin object to be measured, such as a solar cell, the two clamping portions 32 of the first insulating member 2 and the second insulating member 3 can be effectively prevented from pressing the conductive member 4, thereby ensuring that the conductive member 4 can work normally.
Alternatively, referring to fig. 1, the distance between the surface of the mounting portion 31 of the second insulating member 3 adjacent to the conductive member 4 and the surface of the clamping portion 32 adjacent to the conductive member 4 is greater than the distance between the surface of the mounting portion 31 of the first insulating member 2 adjacent to the conductive member 4 and the surface of the clamping portion 32 adjacent to the conductive member 4. By the arrangement, the multimeter pen 100 can be used for measuring the resistance of the edge of a measured object with different thicknesses, such as a solar cell with different thicknesses, and the universality of the multimeter pen 100 is improved.
According to some embodiments of the present invention, the outer surface of the conductive member 4 protrudes from the outer surface of the mounting portion 31. For example, in the example of fig. 1, one side surface of the corresponding clamping portion 32 of the conductive member 4 protrudes out of one side surface of the corresponding clamping portion 32 of the mounting portion 31. Therefore, the side face of the measured object such as the edge of the solar cell can be effectively ensured to be only contacted with the conductive piece 4 during measurement, and the accuracy of the measured data can be further ensured.
Further, the pen body 1 is formed with an external thread, for example, as shown in fig. 1, the right end of the pen body 1 is provided with an external thread of a certain length. The multimeter pen 100 further comprises a locking member 5, the locking member 5 being provided on a side of the second insulating member 3 remote from the conductive member 4 (e.g., the right side in fig. 1), the locking member 5 having an internal thread for mating with the external thread.
When the multimeter pen 100 is used for measurement, an edge of an object to be measured, such as a solar cell, is placed between the first insulating member 2 and the second insulating member 3, for example, the edge of the object to be measured, such as a solar cell, can be pressed close to the clamping portion 32 of the first insulating member 2, the locking member 5 is rotated, the internal thread of the locking member 5 is matched with the external thread of the pen body 1, the second insulating member 3 is pushed to move along the central axis of the pen body 1 toward the direction of the first insulating member 2 (for example, the leftward direction in fig. 1) until the clamping portions 32 of the first insulating member 2 and the second insulating member 3 clamp two surfaces in the thickness direction of the object to be measured, such as a solar cell edge, and the lower surface of the conductive member 4 can be vertically contacted with the side surface of the object to be measured, such as a solar cell edge, and the multimeter measures the resistance. And after the measurement is finished, loosening the locking piece 5, moving the second insulating piece 3 rightwards, taking out the solar cell, and finishing the whole measurement process. Therefore, the measuring method is simple, and the measured data is high in accuracy and good in repeatability.
According to some embodiments of the present invention, two handles 51 are disposed on the locking member 5 at an interval, and the two handles 51 extend in a direction away from the conductive member 4 along a direction towards the central axis of the pen body 1 and an inclined direction. Referring to fig. 1, the locking member 5 is provided with two handles 51 at an interval from top to bottom, the cross-sectional shape of the handles 51 may be substantially trapezoidal, the upper handle 51 extends obliquely upward in a direction away from the central axis of the pen body 1 and the conductive member 4, and the lower handle 51 extends obliquely downward in a direction away from the central axis of the pen body 1 and the conductive member 4. Therefore, the locking piece 5 can be rotated quickly when the measurement is convenient, the time is saved, and the measurement efficiency is improved.
Alternatively, the conductive member 4 is fixedly connected to the pen body 1, and a side surface of the conductive member 4 is in contact with a side surface of the first insulating member 2. For example, as shown in fig. 1, the left side surface of the conductive member 4 is in contact with the right side surface of the first insulating member 2. In this way, the position of the conductive member 4 can be effectively fixed.
Optionally, the second insulator 3 is located at the end of the pen body 1. Thus, the replacement and maintenance of the second insulator 3 is facilitated, and the service life of the multimeter pen 100 is increased.
