DETAILED DESCRIPTION
[0021] Reference signs are indicated as: Figs. 1 to 4As shown, according to the embodiment of the present application, a through-coil is provided, comprising a through-coil body 1 for connecting with a mounting hole on a mounting carrier such as an electric control box, etc., the through-coil body 1 has a through hole 11 extending along the cable passing direction, that is, the through-coil body 1 is a hollow structure, the first end of the through-coil body 1 has a first sealing plate 12, which can be assembled integrally with the through-coil body 1 or directly be a part of the through-coil body 1 (integrally formed), the first sealing plate 12 and the wall of the through-coil body 1 form an end head passing hole capable of allowing the end head of the cable to pass, further comprising a second sealing plate 2, which can be embedded in the end head passing hole (that is, the entire plate body of the second sealing plate 2 can be embedded and assembled in the end head passing hole), when the second sealing plate 2 is embedded in the end head passing hole, it can form a sealing plane together with the first sealing plate 12 (at this time, it can be understood that due to the embedding mode of the second sealing plate 2, only the contact part gap between the first sealing plate 12 and the second sealing plate 2, the gap between the second sealing plate 2 and the wall of the through-coil body 1, and the gap between the cable passing hole and the cable exist at the sealing plane, and there will not be a large flow gap caused by the stacked structure in the prior art, especially the gap of the matching surface between the two sealing plates stacked above and below), and the first sealing plate 12 and the second sealing plate 2 jointly enclose to form a cable passing hole, it can be understood that the size of the end head passing hole should not be less than the size of the end head, and the size of the cable passing hole can match the corresponding wire diameter of the cable to be passed, the second sealing plate 2 can be removed from the end head passing hole when the end head of the cable needs to pass, and after the end head of the cable passes, it is embedded in the end head passing hole, so that the through position of the end head passing hole is planarly sealed by the second sealing plate 2. In this technical solution, the relative position relationship between the end head passing hole and the second sealing plate 2 realizes the passing of the large-size end head of the cable and the sealing after passing, that is, the through-coil not only meets the passing of the large-size position of the cable, but also meets the sealing problem after passing, and the planar sealing between the first sealing plate 12 and the second sealing plate 2 can effectively reduce the matching gap therebetween, so that the sealing effect of the through-coil after passing is better. It should be noted that when the second sealing plate 2 in the present application is embedded in the end head passing hole, the first sealing plate 12 and the second sealing plate 2 can form a continuous sealing surface around the circumference of the cable.
[0022] In one specific embodiment, the insertion of the second sealing plate 2 is achieved by pushing along the direction of the depth of the through hole 11, and the removal direction of the second sealing plate 2 is just the opposite. Preferably, the overline coil body 1 and the second sealing plate 2 are formed by injection (hard plastic or other hard material) to effectively prevent the hand from passing through the sealing plane to the inside of the corresponding electric control box after the sealing plane is formed, and to prevent the occurrence of electric shock.
[0023] It can be understood that the second sealing plate 2 should be reliably and stably in the end head through hole, which can be connected with the overline coil body 1 by external bolts, and in some embodiments, when the second sealing plate 2 is inserted into the end head through hole, the second sealing plate 2 is clamped with the overline coil body 1, so as to simplify the process of sealing positioning.
[0024] The outer contour of the over-coil body 1 can be circular, square, etc., and further, the through hole 11 is a cylindrical hole, at this time, the second sealing plate 2 further has an arc wall 21 matched with the inner side of the wall of the over-coil body 1, the arc wall 21 extends along the depth direction of the through hole 11 to the second end of the over-coil body 1, thereby guiding the embedding process of the second sealing plate 2, and further, the arc wall 21 is provided with a positioning elastic buckle 22, the second sealing plate 2 is clamped with the over-coil body 1 through the positioning elastic buckle 22, and correspondingly, the over-coil body 1 is provided with a clamping groove 131, when the second sealing plate 2 is embedded in the end running hole, the positioning elastic buckle 22 can be inserted into the clamping groove 131, of course, when the second sealing plate 2 needs to be removed, the operator needs to exert force to make the positioning elastic buckle 22 out of the clamping groove 131, which can effectively prevent the operator from mistakenly removing the second sealing plate 2 during operation. The matching of the arc wall 21 and the inner side of the wall of the over-coil body 1 can make the embedding or removing process of the second sealing plate 2 more reliable and smooth. In some embodiments, the arc wall 21 and the inner side of the wall of the over-coil body 1 have a sliding structure to guide the rotation of the arc wall 21 around the central axis of the through hole 11, at this time, the second sealing plate 2 is connected with the over-coil body 1 to form an integral body in the embedded or removed state, thereby eliminating the defect that the over-coil component is scattered and easily lost. Specifically, the sliding structure includes a sliding groove 13 formed on the inner side of the wall of the over-coil body 1, and the arc wall 21 has a sliding rail 23, the groove width of the sliding groove 13 is greater than the width of the sliding rail 23, so that the second sealing plate 2 can be displaced along the axial direction of the over-coil body 1 to ensure that the second sealing plate 2 can be embedded into the end running hole, for example, the groove width of the sliding groove 13 is greater than the width of the sliding rail 23 by one thickness of the first sealing plate 12 in the embedding direction of the second sealing plate 2.
[0025] In some embodiments, the first sealing plate 12 and the second sealing plate 2 are respectively half-ring plate bodies, when the second sealing plate 2 is embedded in the end running hole, the two are combined to form a circular plane, thereby forming a circular sealing.
[0026] The sliding groove 13 can be a ring groove, and in some embodiments, the sliding groove 13 can also be a spiral groove, the lead and spiral angle of the spiral groove should match the embedding process requirements of the second sealing plate 2, so that the second sealing plate 2 can have a movement displacement close to or away from the first sealing plate 12 during rotation; in some embodiments, the positioning elastic buckle 22 is on the sliding rail 23, and correspondingly, the clamping groove 131 is in the sliding groove 13.
[0027] In some embodiments, the cable passing hole is embedded with a sealing rubber ring 3 to further seal the gap between the cable and the cable passing hole. It is understood that in some cases where the sealing requirement is not high, the sealing rubber ring 3 can not be embedded. The outer peripheral wall of the sealing rubber ring 3 is provided with a corresponding embedding ring groove. Due to the large deformation capacity, the sealing rubber ring 3 can be deformed and embedded in the embedding ring groove after the cable passing hole wall edge is forced.
[0028] In some embodiments, the wall body of the wire passing ring body 1 is provided with a clamping structure 14 on the outer side, which can be an elastic buckle for example, so that the wire passing ring body 1 cannot be easily disassembled after being assembled with the corresponding mounting hole. Preferably, the buckle position is located on the inner side of the corresponding electrical control box and the like mounting carrier, so that the disassembly of the wire passing ring body 1 can only be carried out from the inner side, thereby ensuring that the wire passing ring body 1 cannot be easily damaged.
[0029] According to the embodiments of the present application, an electrical control box is also provided, which comprises a box body, the box body is provided with a mounting hole, and the mounting hole is provided with a wire passing ring.
[0030] According to the embodiments of the present application, an air conditioner is also provided, which comprises an electrical control box, and the electrical control box is the above-mentioned electrical control box.
[0031] It is easy for those skilled in the art to understand that the above-mentioned advantageous modes can be freely combined and superimposed without conflict.
[0032] The above is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application. The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and modifications can be made, which should be regarded as the protection scope of the present application.
