It should be noted that, the present embodiment is an improvement on the structure and the installation manner of the main housing of the excitation controller, and the control principle and the operation principle of the excitation controller are the prior art, which are not the main points of the present embodiment, and are not described herein again.

The main shell comprises a bottom shell 3 and a cover plate 4, the bottom shell 3 is provided with an accommodating cavity 31 for mounting the main control board, the surface of the main shell is provided with an annular groove 32 along the opening circumference of the accommodating cavity 31, and the cover plate 4 is provided with an annular boss 41 clamped with the annular groove 32; a first annular sealing boss 42 and a second annular sealing boss 43 are further arranged on two sides of the annular boss 41, the first annular sealing boss 42 is accommodated in the accommodating cavity 31 and attached to the inner side surface of the accommodating cavity 31, and the second annular sealing boss 43 is arranged on the outer side surface of the bottom shell 3 and attached to the outer side surface of the bottom shell 3; a plurality of elastic positioning pieces 33 are uniformly distributed on the inner side surface of the accommodating cavity 31 along the circumferential direction thereof, and positioning holes 44 respectively matched with the elastic positioning pieces 33 one by one are arranged on the first annular sealing boss 42; an elastic sealing layer (not shown) is additionally arranged on the inner side surface of the annular groove 32.

It should be noted that, the main shell structure of traditional controller has been simplified to this embodiment, on the basis of the joint through annular groove 32 and annular boss 41 between drain pan 3 and the apron 4, rethread joint in two annular seal bosses of the inside and outside both sides of holding chamber 31 opening, respectively with the inside and outside both sides butt of holding chamber 31, make the splice of drain pan 3 and apron 4 form the U type seal structure of a plurality of end to end connections, effectively prevent external water or dust from getting into the main shell body from splice between them in, improve its waterproof sealing performance, and simultaneously, increase the elastic sealing layer in annular groove 32, further improve the joint power between annular groove 32 and the annular boss 41, and simultaneously, further improve the butt leakproofness between the two, through multiple structural design, improve waterproof sealing performance greatly. And the elastic positioning piece 33 is clamped with the positioning hole 44, so that the installation stability between the bottom shell 3 and the cover plate 4 is further ensured.

Specifically, when the bottom case 3 and the cover plate 4 are spliced, the annular boss 41 on the cover plate 4 is inserted into the annular groove 32 on the surface of the bottom case 3, it should be noted that, because the annular boss 41, the first annular sealing boss 42 and the second annular sealing boss 43 are respectively inserted into the annular groove 32 and the inner side and the outer side of the opening of the accommodating cavity 31, and are tightly attached to each other, during the splicing process of the bottom case 3 and the cover plate 4, the elastic positioning member 33 on the inner side of the accommodating cavity 31 is compressed by the extrusion force of the side of the first annular sealing boss 42, thereby ensuring that the annular boss 41, the first annular sealing boss 42 and the second annular sealing boss 43 are respectively and smoothly inserted into the inner side and the outer side of the opening of the annular groove 32 and the accommodating cavity 31, when the bottom case 3 and the cover plate 4 are installed in place, the elastic positioning members 33 respectively correspond to the positioning holes 44 one to one, and, stretch out to in the locating hole 44 under the effect of the elastic restoring force of self to the joint guarantees the installation stability between drain pan 3 and the apron 4.

Simultaneously, an elastic sealing layer is add to annular groove 32 medial surface, and this elastic sealing layer sets up to an elastic rubber sealing layer, the elastic rubber sealing layer viscose is fixed in annular groove 32 medial surface can extrude the elastic sealing layer after annular boss 41 inserts annular groove 32 to the gap between annular groove 32 and the annular boss 41 can further be filled to the elastic sealing layer, can guarantee the stability of installation between the two, can improve waterproof sealing performance again.

When needs are separated bottom shell 3 and apron 4, only need extract apron 4 hard, apron 4 receives ascending external force after, and the elastic positioning element 33 of joint in locating hole 44 receives ascending external force equally, and at this moment, elastic positioning element 33 can receive the extrusion force of locating hole 44 side and shrink to with the joint power contact between the two, guarantee to separate smoothly between apron 4 and the bottom shell 3, accomplish the dismantlement.
