Technical Field
[0001] The utility model relates to the technical field of inductor coil detection equipment, in particular to a portable detection tool for an inductor coil. Background Art
[0002] An inductor is a device that works on the principle of electromagnetic induction. In the prior art, inductors are classified into coil-type inductors, iron core inductors and air core inductors according to their structure. Currently, air core inductors are relatively long and mostly have a small diameter, making their overall structure slender. At the same time, because they are mostly used in small parts, their size is small. In the prior art, most of the detection equipment for inductors is medium-to-large-sized equipment. When faced with a large number of small or micro air core inductors, the detection efficiency is low because of the single number of detections. At the same time, the operation of medium-to-large-sized detection equipment is complicated, further reducing the detection efficiency. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the utility model provides a portable detection tool for an inductor coil, so as to solve the problem that the detection of small inductor coils in the existing technology is relatively cumbersome and the detection efficiency is low.
[0004] In order to achieve the above-mentioned purpose, the utility model provides a portable detection tool for an inductor coil, comprising a fixed seat and a clamping seat, the fixed seat and the clamping seat are arranged opposite to each other and a sliding groove is formed therebetween, a clamp for clamping an external inductor coil is fixed on the clamping seat, the clamping end of the clip is arranged toward the fixed seat, a multimeter for detecting various performances of the inductor coil is arranged on the fixed seat, the multimeter comprises two detection heads for contacting the inductor coil, a fixing part for fixing the two detection heads and a driving part for driving the fixing part to slide horizontally in the sliding groove are arranged on the fixed seat, two contact terminals are provided on the fixed seat for cooperating with the external inductor coil to form a loop after the clamping seat slides a certain distance toward the fixed seat, and both of the contact terminals are provided with conductive wires for connecting with the external circuit.
[0005] The above technical solution is beneficial in that: the operator moves the inductor coil to be tested into the sliding groove and presses the clamp to clamp the inductor coil to be tested, and the air-core inductor coil is composed of a cylindrical winding portion and terminal portions at both ends of the winding portion. The clamp clamps the winding portion of the air-core inductor coil, and then the operator pushes the clamping seat to move the clamping seat toward the fixed seat. At this time, the sliding groove gradually shrinks, that is, the distance between the clamping seat and the fixed seat gradually shrinks. When the clamping seat moves a certain distance, the two terminal portions of the air-core inductor coil are respectively in contact with the two contact terminals, and the two contact terminals are both provided with conductive wires for connecting to the external circuit. The two contact terminals cooperate with the air-core inductor coil to form an energized circuit, and when the two terminal parts of the air-core inductor coil are respectively in contact with the two contact terminals, the winding part is in contact with the two detection heads, so that the air-core inductor coil can be detected by the multimeter when the air-core inductor coil is energized. The entire detection process only needs to be clamped by the clip and the sliding seat is pushed to slide to realize the multimeter detection of the air-core inductor coil. The entire detection process is fast and efficient, thereby improving the detection efficiency of the air-core inductor coil, thereby determining the qualified rate of the detected air-core inductor coil, and at the same time, there is no need to install medium and large detection equipment, thereby reducing cost expenditure and medium The space required for large-scale detection equipment accounts for a large proportion, and the use of this technology increases the number of air-core inductor coils to be detected, thereby improving production efficiency; in the above technology, the detection head is fixed by a fixing part and the fixing part is driven by a driving part to slide horizontally in the sliding groove, so as to adjust the position of the detection head in the sliding groove, and then when the terminal part of the air-core inductor coil contacts the corresponding contact terminal, the detection head can always be in synchronous contact with the winding part of the air-core inductor coil, that is, by adjusting the position of the detection head to adapt to air-core inductor coils of different shapes and sizes, so as to increase the detection range; in the above technology, the multimeter is a prior art, which connects the two detection heads to the inductor The contact of the coil realizes the detection of the voltage, resistance and current of the inductor coil, and the corresponding values are displayed on the digital display screen after the detection, which makes it easy for the operator to determine whether the detected inductor coil is compliant. Since the multimeter is a prior art, its structure and function will not be described in detail. In the above technology, the contact terminal is connected to the external circuit through a conductive wire to realize the function of the contact terminal to transmit power. Because its power-on principle and the structure connecting the conductive wire with the external circuit are prior art, they will not be described in detail. At the same time, the conductive wire can be connected to an external device capable of transmitting power instead of the circuit according to actual needs, so as to ensure power transmission.

[0007] The benefits of adopting the above technical solution are: in the above technology, when the detection head needs to be fixed, the operator inserts the detection head into the socket, so that the detection head and the fixing sleeve are initially matched and initially fixed, and then the operator screws in the fixing bolt so that the abutting end of the fixing bolt abuts against the outer peripheral wall of the detection head, and the outer peripheral wall of the detection head is wrapped with an insulating layer, that is, the abutting end abuts against the insulating layer to fix the detection head in the socket, thereby ensuring that the detection head will not slip or shake when the inductor coil contacts the detection head, causing the detection result to be affected; in the above technology, the setting of the fixing bolt makes it easy for the operator to disassemble and fix the detection head, thereby improving the detection efficiency.

[0009] The benefit of adopting the above technical solution is that when it is necessary to adjust the position of the detection head in the sliding groove, the operator only needs to rotate the adjusting rod so that the adjusting rod drives the sliding rod to slide in the sliding hole, and when the sliding rod slides, the fixed sleeve slides in the sliding groove, thereby realizing the adjustment of the position of the detection head in the sliding groove, and then the detection head can contact the winding part of the inductor coil, further improving the detection efficiency and the detection adaptation range.
