Specific implementation mode

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figure 1-5 , an embodiment provided by the present invention:

[0023] An explosion-proof reactor includes a yoke 1 and a coil 11. The coil 11 is wound around the outer surface of the yoke 1. The surface of the yoke 1 is connected with an upper clamping piece 2 by bolts. The inner side of the coil 11 is inserted and connected with a conductive sheet 3. The surface of the conductive sheet 3 is fixedly connected with a connecting column 31. The outer surface of the connecting column 31 is sleeved with a spring piece 32. The surface of the spring piece 32 is fixedly connected with an abutting ball 33. The outer surface of the yoke 1 is fixedly connected with a lower clamping piece 4. The surface of the lower clamping piece 4 is penetrated with an adjusting groove 41. The inner side of the adjusting groove 41 is provided with a sliding groove 42 and a limiting groove 45. The inner side of the adjusting groove 41 is slidably connected with a mounting plate 43. The surface of the mounting plate 43 is penetrated with a mounting groove 44. Both ends of the mounting plate 43 are fixedly connected with a slider 48 and a screw rod 46. The outer surface of the screw rod 46 is threadedly sleeved with a screw sleeve 47. Through the connection between the conductive sheet 3 and the coil 11, under the action of the conductive sheet 3, the power supply of the coil 11 is realized. Under the connection between the yoke 1 and the upper clamping piece 2, through the action of the upper clamping piece 2, the supporting effect of the position of the conductive sheet 3 in the coil 11 is realized. Under the action of the lower clamping piece 4, the overall support operation of the yoke 1 is completed.

[0024] Furthermore, the cross-section of the yoke 1 is in the shape of a "mountain". The coils 11 are distributed in three groups on the surface of the yoke 1, and the upper clamping pieces 2 and the lower clamping pieces 4 are both distributed in two groups at both ends of the yoke 1. Through the connection between the yoke 1 and the upper clamping piece 2, under the action of the upper clamping piece 2, the limiting and supporting effect of the position of the conductive sheet 3 on the yoke 1 is realized.

[0025] Furthermore, the conductive sheet 3 has an "L" shaped cross section. The conductive sheet 3 is electrically connected to the coil 11 through a wire. The conductive sheet 3 is distributed in three groups on the same side surface where the coil 11 and the yoke 1 are in contact. Through the electrical connection between the conductive sheet 3 and the coil 11, the coil 11 is powered by the conductive sheet 3.

[0026] Furthermore, a circular hole is formed through the surface of the conductive sheet 3. The ball 33 abuts against the circular hole through the spring sheet 32. The spring sheet 32 ​​is fixedly connected to the outer surface of the conductive sheet 3 through the connecting post 31. Through the connection between the conductive sheet 3 and the connecting post 31, and the connection between the spring sheet 32 ​​and the ball 33, the elasticity of the spring sheet 32 ​​itself achieves a tight abutment between the ball 33 and the circular hole on the conductive sheet 3, thereby improving the stability of the connecting wire on the circular hole.

[0027] Furthermore, the lower clamp 4 has an "L" shaped cross section. The mounting plate 43 is slidably connected to the lower clamp 4 through the adjusting groove 41. The limiting groove 45 penetrates the inner surface of the adjusting groove 41. Through the connection between the lower clamp 4 and the yoke 1, the lower clamp 4 provides support for the yoke 1. Under the sliding connection between the adjusting groove 41 and the mounting plate 43, the position of the mounting plate 43 on the lower clamp 4 can be adjusted.

[0028] Furthermore, the mounting grooves 44 are distributed in two sets on the surface of the lower clamp 4, and the slider 48 is block-shaped and slidably connected to the sliding groove 42. Through the connection between the mounting groove 44 and the mounting plate 43, the connecting piece can easily pass through the mounting plate 43 under the action of the mounting groove 44, so as to achieve the connection and use effect of the mounting plate 43.

[0029] Furthermore, the screw 46 consists of two parts: one part is block-shaped and the other part is rod-shaped. The screw 46 passes through the limiting groove 45 and is sleeved with the threaded sleeve 47. Under the sliding connection of the slider 48 and the sliding groove 42, the connection between the screw 46 and the threaded sleeve 47 completes the adjustment operation of the position of the mounting plate 43 in the adjustment groove 41, thereby improving its performance and effect.

[0030] Working principle: When wiring coil 11, connect the connecting wire to the round hole on conductive plate 3, and then connect spring plate 32 to conductive plate 3 through connecting post 31. At this time, ball 33 and round hole press against each other, so as to press against the connecting wire, which facilitates soldering and improves the stability of its connection.

[0031] When the yoke 1 is installed and used, the mounting plate 43 and the screw 46 are connected, and the screw 46 and the screw sleeve 47 are connected. At this time, the screw sleeve 47 is rotated, so that the screw 46 slides in the limiting groove 45 and the slider 48 slides in the sliding groove 42. This changes the position of the mounting plate 43 in the adjusting groove 41, increases the range of use of the mounting plate 43 on the lower clamp 4, and thus improves the range and performance of the yoke 1 during installation.

[0032] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
