DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] The utility model provides Figure 1-3 An inductor that is easy to install is shown, comprising a fixed end 2 and a coil 6 installed on the upper side of the fixed end 2;

[0025] The circular outer wall at the lower end of the coil 6 is fixedly connected with an internal pin 4 passing through the fixed end 2 to guide the flow of current;

[0026] A wireless transmitter 3 is provided inside the fixed end 2 to detect the current data and transmit it wirelessly;

[0027] The upper outer wall of the fixed end 2 is fixedly connected with a fixing frame 1 to limit the position of the coil 6. The pin 4 is inserted between the corresponding power generation elements. The power generation element will emit current and transmit it to the coil 6 through the pin 4 for electromagnetic induction, and detect the value. The detected value will be transmitted to the outside through the wireless transmitter 3.

[0028] A protective cover 8 is provided on the upper side of the fixed end 2 to shield the coil 6. A plurality of heat dissipation holes 9 are equidistantly provided on the inner side of the right end outer wall of the protective cover 8 and are passed through the protective cover 8. A moisture-absorbing pad 14 is provided on the inner wall of the lower end of the protective cover 8 to absorb moisture inside the protective cover 8. When the inductor is in use, the coil 6 is covered and protected by the protective cover 8 to prevent the coil 6 from being damaged by external factors. At the same time, heat can be dissipated through the heat dissipation holes 9 and moisture intruding into the protective cover 8 can be absorbed by the moisture-absorbing pad 14.

[0029] like Figure 1 , Figure 2 and Figure 3 As shown, threaded holes 5 opening forward are provided inside the front end outer wall of the fixed end 2 and near the left and right sides respectively, a connecting plate 10 is fixedly connected to the front end outer wall of the protective cover 8, a fixing screw 11 penetrating backwards into the threaded hole 5 is provided on the front end outer wall of the connecting plate 10 to limit the position of the protective cover 8, a limiting block 12 is fixedly connected to the lower end outer wall of the protective cover 8 to limit the position of the moisture-absorbing pad 14, a plurality of air holes 13 penetrating up and down are equidistantly provided inside the lower end outer wall of the protective cover 8, and the protective cover 8 is made of stainless steel.

[0030] When installing the protective cover 8, after aligning the connecting plate 10 with the threaded hole 5, the fixing screw 11 is screwed backwards and into the threaded hole 5 to fix the protective cover 8 on the fixing frame 1. The moisture-absorbing pad 14 can be dried by air through the air vent 13 in a dry environment.

[0031] like Figure 2 and Figure 4 As shown, the heat dissipation hole 9 is inclined, and a space for placing the coil 6 is reserved inside the protective cover 8.

[0032] The downwardly inclined heat dissipation holes 9 can reduce the occurrence of dust entering the protective cover 8 through the heat dissipation holes 9, and by reserving space for placing the coil 6, it is avoided that the protective cover 8 contacts the coil 6 immediately after being deformed.

[0033] like Figure 1 As shown, a partition 7 is fixedly connected inside the fixing frame 1, the lateral length of the pin 4 gradually decreases from top to bottom, the coil 6 is made of brass material, and a column around which the active coil 6 is wound is fixedly connected between the outer walls at the front and rear ends of the two fixing frames 1.

[0034] The partition 7 is provided to separate the two coils 6 to avoid mutual interference of electromagnetic fields between the two coils 6 during operation. The coil 6 made of brass material has better conductivity and electrical induction.

[0035] The implementation principle of this embodiment is: first, put the protective cover 8 on the fixing frame 1 and fix it with the fixing screws 11, then insert the pin 4 into the power generation element to be tested, the power generation element emits current, which is transmitted through the pin 4 to the coil 6 for circulation, and the electromagnetic induction emitted will be detected by the wireless transmitter 3 and the value will be transmitted to the outside. After the value is detected, the fixing frame 1 can be pulled out.
