The specific meaning of the above terms in the present utility model can be understood by those of ordinary skill in the art according to the specific circumstances.

Fig. 1 is an exploded schematic diagram of a frequency converter according to an embodiment of the present utility model. Fig. 2 is a schematic structural diagram of a frequency converter according to an embodiment of the present utility model. As shown in fig. 1 and 2, the frequency converter may mainly include: a frequency converter housing composed of an upper housing 11 and a lower housing 12, a heat sink 20, and an electrical component 30.

Wherein the electrical components 30 may be assembled and secured to the heat sink 20 to form a variable frequency assembly. The frequency conversion module can be accommodated in an accommodating space surrounded by the upper housing 11 and the lower housing 12.

Specifically, the bottom of the upper case 11 is open. It is generally rectangular with two opposing housing sides 111, a housing front 112, a housing back 113, and a housing top 114. At least a portion of both housing sides 111 is provided with an anti-slip structure.

In some embodiments, with continued reference to FIG. 1, the housing side 111 is provided with a plurality of channel grooves 115. These grooves 115 are arranged at predetermined intervals and orientations on the side of the housing, and increase friction by means of the rugged surface, thereby forming the above-mentioned anti-slip structure.

The lower housing 12 has edges that fit into the bottom opening of the upper housing. The bottom surface of the lower housing 12 facing away from the upper housing is provided with a groove 121 of a predetermined width.

The slide plate buckle 13 is arranged on the bottom surface of the lower shell and can reciprocate relative to the lower shell along a preset direction. Wherein the predetermined direction is perpendicular to the extending direction of the groove 121. Thus, in the locked state, at least a part of the slide plate buckle 13 enters the groove 121 and abuts against the guide rail 40 passing through the groove 121, thereby fixing the frequency converter on the guide rail a.

In some embodiments, the bottom opening of the upper case 11 is detachably connected with the lower case 12 to form an accommodating space for accommodating the inverter. For example, with continued reference to fig. 1, the upper and lower housings may be connected by a snap fit. The edge of the lower shell can be provided with a plurality of male fasteners (for example, 4 male fasteners), and the corresponding position of the upper shell is provided with a female fastener matched with the male fastener. Thereby, the upper shell and the lower shell are detachably and fixedly connected together through 4 buckles.

In some embodiments, as shown in fig. 3, the bottom surface of the lower housing 12 is provided with a receiving groove 122 for receiving the slide plate buckle, and a locking protrusion 123 is further provided in the region where the receiving groove is located.

Correspondingly, as shown in fig. 3, the slide plate buckle 13 includes: a clasp body 131 and a pair of resilient clips 132.

One end of the buckle body 131 forms a pressing portion P1, and the other end forms a locking portion P2. The elastic clip 132 has elastic deformability and can be engaged with the locking protrusion 123 to maintain the slider clip 13 in a locked state.

Specifically, referring to fig. 3, at least a portion of the buckle body 131 is a hollow area. The elastic clamping member 132 is located in the hollow area, and its end is triangular and adapted to the locking protrusion 123.

In the actual use process, as shown in fig. 2, in the locking state, the locking part enters the groove. In the non-locking state, the pressing portion protrudes from the lower case. The user can switch to the locked state by applying pressure to the pressing portion to deform and lock the elastic clamp 132 into the position where the locking protrusion is located.

It should be noted that, the frequency converter according to the embodiment of the present utility model may further be added with one or more of the following structures or related functional modules, so as to meet different use requirements. For example, as shown in FIG. 1, the frequency converter may also include a fan 40. The fan 40 is disposed on the front surface 112 of the housing, and enhances heat dissipation through the hollowed-out area of the front surface 112 of the housing. Alternatively, the frequency converter may further include a tag 50 fixed to an outer surface of the upper case, and further include a knob 61, a panel 62, a light guide post 63, a top cover 64, a fixing screw 65, a stud 66, and the like. The electrical component 30 may include a control board 31 and a power board 32, and nylon posts 33 to help secure the two.

In the practical use process, the control board, the power board and other electrical components can be assembled on the radiator first to form a complete transformer assembly. And then after the transformer assembly slides into the installation position of the lower shell, the upper shell is buckled and fixed on the lower shell, so that the complete installation and assembly operation can be completed. The complete frequency converter can be fixed in a specific position by means of screws 14 or can be fixed in a target position by means of a rail.

The foregoing is a further detailed description of the utility model in connection with specific/preferred embodiments, and it is not intended that the utility model be limited to such description. It will be apparent to those skilled in the art that various modifications and improvements can be made without departing from the spirit of the utility model, and these are all within the scope of the utility model.
