Technical Field

[0001] The invention relates to the technical field of electrical and electronic electricity measurement, and in particular to an electricity measurement experimental device used for an electrical and electronic training platform. Background Art

[0002] Electrical and electronic technology is a professional course set up by the Ministry of Higher Education in colleges and universities. Since electrical and electronic technology is highly theoretical, in order to facilitate students to better understand it, practical courses are often arranged while theoretical teaching is carried out; the most common equipment in practical courses is the electrical and electronic training platform, among which the electrical measurement experiment device is the most basic module on the training platform. The electrical measurement experiment device can be used in conjunction with electronic components such as experimental boxes, power supplies, and wires to meet the needs of basic experimental operations.

[0003] The existing electrical testing devices usually only consider the adjustment and modification of circuit components, intending to avoid the problem of complicated and confusing flying wires. It does not take into account that the existing electrical testing devices generally connect the circuit by cooperating with the electrical connection jack on the electrical testing device when connecting the circuit. However, when the existing electrical connection holes are not used for a long time or are not cleaned, some dust is likely to gradually accumulate on the electrical connection holes, which is likely to cause poor contact in subsequent experiments, thereby affecting the normal progress of the experiments. In addition, the non-through hole structure design is not easy to clean. At the same time, the existing electrical connection holes are likely to cause looseness between the connection holes and the connectors after frequent use, resulting in poor contact, which is not conducive to experimental operation. Summary of the invention

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] Combine the following Figures 1 to 8 The invention describes an electrical measurement experimental device for an electrical and electronic training platform.

[0032] In one embodiment, an electrical measurement experiment device for an electrical and electronic training platform includes a test bench 100, a power connection piece 300 and an abutment piece 500; a power plug hole 221 is provided on the test bench 100, and the power plug hole 221 is used to insert a plug connector 700; the power connection piece 300 is located on one side of the power plug hole 221, and when the power connection piece 300 is pushed by an elastic piece 400, its surface enters the power plug hole 221 and is engaged with one side of the plug connector 700; the abutment piece 500 is movably arranged on the inner side of the power plug hole 221 and abuts against the upper side or the lower side of the plug connector 700, and when the abutment piece 500 rotates around the power plug hole 221, the abutment piece 500 will come into contact with the surface of the power connection piece 300, and will rotate back to its original position under the action of the reset piece 600.

[0033] In the above-mentioned electrical measurement experimental device for the electrical and electronic training platform, under normal conditions, the power connection part 300 is affected by the elastic part 400 and abuts against the side of the plug hole 221, and a part of the power connection part 300 is located in the plug hole 221, while the abutting part 500 is located in the power connection hole 350. When installing the plug connector 700, as the plug connector 700 is inserted, the power connection part 300 will be pushed out of the plug hole 221 until the plug connector 700 is plugged in. The power connection part 300 will re-enter the plug hole 221 and abut against one side of the plug connector 700. When the plug connector 700 is separated from the plug hole 221 and the plug hole 221 has not been used for a long time, Dust may accumulate inside it. At this time, the abutment 500 is controlled to rotate around the plug hole 221. During the rotation, the abutment 500 will scrape off the dust on the inner surface of the plug hole 221. At the same time, the surface of the power receiving part 300 abutting in the plug hole 221 will also come into contact with the abutment 500. During the contact, the dust on the surface of the power receiving part 300 will also be taken away, thereby avoiding poor contact caused by dust during the experiment. In addition, since the abutment 500 is located in the plug hole 221 and the power receiving part 300 abuts against one side of the plug hole 221, the plug connector 700 is more secure after insertion and will not easily loosen or fall off.

[0034] In one embodiment, the test bench 100 includes two panels 210, an electric plug tube 220 and a connecting plate 230; the two ends of the electric plug tube 220 pass through the two panels 210 respectively, the interior of the electric plug tube 220 is an electric plug hole 221, a plurality of first through grooves 222 are provided on the left and right sides of the electric plug tube 220, a second through groove 223 is provided on the upper and lower sides of the electric plug tube 220, the plurality of first through grooves 222 are linearly spaced along the central axis direction of the electric plug tube 220, and the connecting plate 230 is connected between the two panels 210.

[0035] Specifically, in Figure 1 In the figure, a panel 210 is exposed in the upper part of the test bench 100, and another panel 210 is located inside the test bench 100 and cannot be directly observed from the outside.

[0043] Specifically, the two second limiting holes 224 are not symmetrically arranged with respect to the longitudinal section of the plug-in tube 220 , and the distances between the two ends of the second limiting holes 224 and the longitudinal section of the plug-in tube 220 are different.

[0044] In one embodiment, the reset member 600 includes an arc plate 610 and a connecting rod 620. The arc plate 610 is attached to the outer surface of the plug-in tube 220. One end of the connecting rod 620 is connected to the arc plate 610, and the other end of the connecting rod 620 passes through the second limiting hole 224 and is connected to the upper surface of the block 510.

[0045] Specifically, two first limiting holes 211 are provided on the panel 210, and the first limiting holes 211 are bent around the plug-in tube 220, and the two first limiting holes 211 are arranged in a ring array structure relative to the central axis of the plug-in tube 220.
