Edge of said opening is provided with a limiting flange extending outwardly, is provided in the edge of the cover body with the limit flange limit curve is matched with. The limit curve groove towards the middle of the body of the cover be absorbed. The utility model compared with the prior art has the following beneficial effects: the body of the cover and the case of the substitute the original sleeve waterproof of the frequency-conversion controller, the installation process of the inverter controller is reduced, simplifying the structure of the frequency converter controller; is arranged on the back surface of the box body for protecting the waterproof edges of the radiator, the radiator can prevent water from entering the box damage the internal circuit, the two kind of structure makes the variable-frequency controller water-proof performance is greatly improved. Description of drawings Figure 1 is the utility model upward chart; Figure 2 is-structure diagram of the utility model; Figure 3 is perspective view of the utility model regards left structure; Fig. 4 is a stereo-structure diagram of the utility model. Mode of execution In order to ensure that the purpose of the utility model, technical scheme and the beneficial effect is more clear, the following binding with photos and specific embodiment, the utility model discloses detailed description waterproof universal a frequency converter. The specific embodiment described is merely used for explanation of the utility model, is not used for limiting the utility model. With reference to Figure 1 to 4 illustrated, the utility model relates to a waterproof universal frequency converter, including the body of the cover 1 and the box 2, the box body 2 a surface provided with an opening 21, the opening 21 is located in the case 2 is erected the front side of the, box body 2 is arranged on the outer surface of the back surface of the used for protecting the radiator water-proof projections 22, box body 2 of the outlet end is set in the box body 2 on the bottom of the vertically positioned. The box body 2 is arranged at a corner of the bottom of the inverted "L" is at right angles-shaped hitch 24, right-angled position hitch 24 towards the bottom of the is provided with a side of the outlet hole 25, right-angled position hitch 24 towards the inner side of the side of the bottom, the outlet hole 25 are respectively set on the two sides of the slot 26, slot 26 is provided with a clamping plate, for sealing dust-proof. The body of the cover 1 and the opening 21 to pull type sleeve is connected with the, opening 21 extending outwards from the edge of the is provided with a limiting flange 23, the cover body 1 is provided with in the edge of the limiting flange 23 of the limit curve is matched with 11, in the body of the cover 1 and the box 2 sleeve, parallel left and right sides of the two limiting flange 23 can enter into or pulled out of the limit curve groove 11, the limiting curve groove 11 absorbed of 12 towards the body of the cover 1 in the middle of, the body of the cover 1 in the corresponding box body 2 is erected on the top of the is arranged on one side of the limiting part 13, a limiting part 13 is provided with a for limiting flange 23 into the limiting curve groove 11. Located at right angles in the hitch 24 towards the bottom of a side face is provided with a gap, is used for making the body of the cover 1 can be carried out by the drawing motion. Such a structure, the utility model is easy to install, can be effectively water-proof, and the screw element. The utility model relates to a back plate of the box body for protecting the outer surface of the radiator is provided with waterproof protruding, from the radiator water can be prevented from entering the box damage the internal circuit. The stated above for the preferred embodiment of the utility model, however, the scope of protection of this utility model is not limited to this, any familiar to technical personnel of the technical field of the utility model disclosed in the context of, it is according to the technical scheme and replacement or change to be equivalent, all belong to the scope of protection of this utility model. The utility model relates to a waterproof general converter, including lid and box, the box simultaneously sets up the opening, and the opening is located the box and erects the front when placing, and the leading -out terminal of box is established and is erect the bottom when placing at the box, what the one corner of bottom half was equipped with down " L " type keeps away sky right angle position, keeps away sky right angle position and is provided with the wire hole towards one side side of bottom, it is inboard towards the side of bottom to keep away sky right angle position, sets up the draw -in groove respectively in the both sides of wire hole, and the draw -in groove is furnished with the cardboard, and the backplate surface of box is equipped with the waterproof arch that is used for protecting the radiator. The utility model discloses a pull formula mode of cup jointing of lid and box replaces original frequency -variable controller's waterproof circle, reduces frequency -variable controller's installation procedure, simplifies the structure of converter controller, setting up the waterproof limit that is used for protecting the radiator at the box back, can preventing that water from getting into the electronic box from the radiator gap and damaging the internal circuit, two kinds of structures make frequency -variable controller waterproof performance improve greatly. 1.
