Description

Accurate measuring device according to wire diameter

The invention relates to an accurate measuring device according to the wire diameter, in particular to a wire diameter accurate measuring device which can replace the appropriate aperture according to the thickness of the wire to obtain a more accurate voltage/current measuring data. .

According to the electronic measuring meter currently used to measure power data such as voltage, current, etc., it has been widely used due to various measurement modes, such as measuring voltage, current, frequency, angle, watt, and lack of... use.

Most of the electronic measuring meters used to measure current, voltage and the like are three-type electric meters or hook-type electric meters. Among them, a hook type electric meter is taken as an example: as shown in the first figure, the conventional hook type electric meter A There is mainly a host A1, and a measuring buckle A2 is opened and closed at the top end of the host A1, and a pressing button A3 is connected to one of the measuring buckles A2, so that the pressing of the pressing button A3 allows One of the measuring buckles A2 is opened, so that the measuring buckle A2 is passed through and wrapped around the wire B, and the measuring ring A2 is used to detect the voltage, current, etc. of the wire B, and finally the detection is performed. The data is displayed on the liquid crystal screen A4 of the host A1.

However, the conventional hook-type electric meter A is too large in measuring the diameter of the buckle A2, that is, the gap between the aperture of the buckle A2 and the electric wire B is too large, so that the conventional hook-type electric meter A is easy to slide on the electric wire B, and In addition, the gap between the aperture of the measuring buckle A2 and the wire B is too large, so that the conventional hook meter A cannot accurately measure the data of the wire B.

According to the present invention, the accurate measuring device according to the wire diameter includes a clamping clamp table and two fastening fasteners. The clamp clamp meter is used as a voltage/current measurement, and one end thereof is provided with two correspondingly opened and closed pressing grips, and the other end thereof is provided with two corresponding measuring portions for opening and closing, which are used by two pressing grips. To control the opening and closing state of the two measuring portions; the two fixing fasteners are respectively coupled to the positions of the two measuring portions of the clip-on pliers, the fixing fastener is provided with a base portion, and the base portion has two fastening portions extending from one side thereof and The other side is recessed with a first clamping portion, and the second fastening portion of the fastening fastener is fixedly coupled to the measuring portion of the clamping clamp table, and the first clamping portions of the two fastening fasteners correspond to each other. And the fixing fastener is movably coupled to the first clamping portion to have at least two fastening components, wherein the fastening components are curved and have a second clamping portion recessed on one side thereof, so that the buckles are buckled The length of the inner diameter of the second clamping portion of the connecting member is sequentially decreased by the first clamping portion.

The technical feature of the present invention is that the first clamping portion of the fastening component is movably coupled with at least two fastening components, and the inner diameter of the second clamping portion of the fastening component is separated by the first clamping portion. Decreasing outwardly and sequentially, that is, the closer to the fastening component of the fastening member, the greater the inner diameter of the second clamping portion; conversely, the further away from the fastening component of the fastening component, the second clamping portion thereof The smaller the diameter, the smaller. In this way, the length of the inner diameter (ie, the aperture) of the second clamping portion of each fastening component is different, and the fastening component of the appropriate aperture can be replaced according to the thickness of the wire, so that the clamp clamp can be surely performed on the wire. Clips, which in turn yield more accurate voltage/current measurements.

The features and advantages of the present invention will be described in detail in conjunction with the accompanying drawings. The present invention is described in detail, but does not limit the scope of the present invention in any way.

Please refer to the second to sixth figures. The present invention discloses an accurate measuring device according to the wire diameter, which comprises a clamping clamp table 1 and two fastening fasteners 2.

The clamp clamp meter 1 is used as a measurement of other values such as voltage/current (such as resistance, frequency, etc.), and the clamp clamp table 1 is provided with two correspondingly pressing and pressing push handles 11 at one end, and the clips are clamped. The other end of the caliper 1 is provided with two measuring portions 12 corresponding to the opening and closing. The measuring portion 12 can be curved and semi-annular. When the two pressing handles 11 are pressed, the two measuring portions 12 are separated and opened. And the two measuring portions 12 are respectively recessed with a curved arc area 121 on the corresponding side edges thereof; further, the clip clamp table 1 is electrically connected with a transmission line 13 for using the transmission line 13 for the clamp clamp meter 1 The measured value is transmitted to a preset detection device.

The two fastening members 2 are respectively movably coupled to the position of the curved portion 121 of the two measuring portion 12, the fixing fastener 2 is provided with a base portion 21, and the base portion 21 has two fastening portions 22 extending on one side thereof and another A first clamping portion 23 is recessed on one side, and the fastening member 2 is coupled to the curved portion 121 of the measuring portion 12 by the two fastening portions 22, so that the fixing fastener 2 can be fixed to the clamping clamp table 1 The measuring portion 12 (as shown in the second figure), and the first clamping portion 23 of the two fixing fasteners 2 are corresponding to each other; and the fixing fastener 2 is provided on the wall surface of the first clamping portion 23 a joint portion 231, such that the first clamping portion 23 of the fixing fastener 2 is movably coupled with at least two fastening elements 3 by the first joint portion 231, and the fastening member 3 is curved and on one side thereof The second joint portion 31 is provided with a second joint portion 32, and the second joint portion 32 is provided with a third joint portion 321 on the wall surface thereof, and the second joint portion 32 and the second joint portion 32 are provided. A clamping portion 23 is bent in the same direction to make the second fastening elements 3 Inner diameter and a length of the engagement portion 32 sequentially decremented by a first clamping portion 23 outwardly.

The fastening elements 3 are sequentially decremented by the first clamping portion 23 outwardly due to the inner diameter of the second clamping portion 32, that is, the second clamping of the fastening component 3 closer to the fastening fastener 2 The length of the inner diameter of the portion 32 is larger; on the contrary, the further away from the fastening member 3 of the fixing fastener 2, the smaller the inner diameter of the second clamping portion 32; therefore, the fastening members 3 can be stacked in sequence. And coupled to the first clamping portion 23 of the fastening fastener 2.

When the fastening elements 3 are coupled to the first clamping portion 23 of the fastening fastener 2 (as shown in the third figure), the fastening component 3 adjacent to the first clamping portion 23 is composed of the second bonding portion 31. In combination with the first joint portion 231, the fastening component 3 adjacent to the first sandwiching portion 23 can be fixedly coupled to the fastening fastener 2; and then the fastening components 3 (ie, not coupled with the first clamp) The fastening elements 3) adjacent to the joint portion 23 are sequentially combined with the second joint portion 31 provided by the second joint portion 31 and the third joint portion 321 of the other fixing piece to reach at least two fastening members. 3 can be stacked in sequence (as shown in the fourth figure).

The present invention is directed to a first application embodiment. As shown in FIG. 5, when the clamp clamp meter 1 is used to measure a thin wire 4 having a small diameter, the buckle of the appropriate aperture can be replaced according to the thickness of the wire 4.
