In order to realize the purpose, the utility model adopts the technical scheme that: the utility model provides a power iron-clad structure, is including top cap, circuit board and the base that assembles in proper order, the circuit board respectively is equipped with the slot in the four corners, it is equipped with T type backing sheet to correspond the slot position on the base, insert the spacing fixed of slot through T type backing sheet between circuit board and the base, the base is equipped with narrow limit and broadside in each outer fringe department, the same top surface of narrow limit and broadside perpendicular to, the narrow limit height is higher than the broadside height, the narrow limit top is equipped with joint portion, joint portion is T style of calligraphy structure, the top cap is equipped with the bayonet socket that corresponds joint portion in relative both ends outer fringe department, it is fixed with joint portion elastic clamping through bayonet socket between top cap and the base.

The top cap is of a concave structure, a through groove is formed in the top cap in a through mode, and the bayonet is arranged at the position of the through groove of the top cap.

The top cover is arranged on the inner sides of the two wide edges of the base, and the top cover is elastically abutted and limited and fixed with the wide edges.

The wide side and the narrow side of the base are spaced.

The base is formed by punching and bending.

The utility model has the advantages that: the utility model provides a power iron-clad structure bends out 4T type backing sheets on the drain pan, and T type backing sheet microcephaly can insert the circuit board slotted hole, and the microcephaly piece of buckling just can easily fix the circuit board, and the bayonet socket is made in the punching of power lid, makes out the I-shaped draw-in groove on the drain pan, utilizes metal elasticity and bayonet socket cooperation structure, but makes the lid drain pan fixed, makes things convenient for product production equipment, the appearance pleasing to the eye, practices thrift the cost.

Detailed Description

As shown in fig. 1-2, a power iron shell structure comprises a top cover 1, a circuit board 2 and a base 3 which are assembled in sequence, wherein slots 4 are respectively arranged at four corners of the circuit board 2, and the slots 4 are designed to be beneficial to balance and stability of connection and support at the four corners and can also be fixed to a certain extent. The base 3 is provided with a T-shaped support sheet 5 corresponding to the slot 4, and the circuit board 2 and the base 3 are limited and fixed by inserting the T-shaped support sheet 5 into the slot 4. It should be noted that, the T-shaped support sheet 5 is designed in an inverted T shape, and serves to support and achieve the function of lateral limitation. In this embodiment, since the T-shaped support piece 5 is formed by stamping and bending, the inclination angle can be adjusted during the installation of the circuit board 2, so that the circuit board 2 is stably installed. The base 3 is provided with a narrow side 6 and a wide side 7 at the outer edge of each side, the narrow side 6 and the wide side 7 are perpendicular to the same top surface, and the height of the narrow side 6 is higher than that of the wide side 7. Broadside 7 all sets up in the edge with narrow limit 6, through the shaping of buckling, its own on the one hand can save casing part terminal surface material, also can play supplementary fixed effect. 6 tops on narrow limit are equipped with joint portion 8, joint portion 8 is T style of calligraphy structure, top cap 1 is equipped with the bayonet socket 9 that corresponds joint portion 8 in relative both ends outer fringe department, it is fixed through

bayonet socket

9 and 8 elasticity joints of joint portion to connect between top cap 1 and the base 3. When the assembly, utilize certain elasticity of metal or material to carry out the joint, mounting structure is firm.

The top cover 1 is of a concave structure, a through groove 10 which is communicated with the top cover 1 is formed in the top cover 1, and the bayonet 9 is arranged at the groove opening of the through groove 10 of the top cover 1. The top cover 1 and the narrow edge 6 are combined to form a box body, and the narrow edge 6 is covered with a cover, and an opening for passing through is further designed on the narrow edge 6. The top cover 1 is arranged on the inner sides of the two wide edges 7 of the base 3, and the top cover 1 and the wide edges 7 are elastically abutted and limited and fixed. The design of broadside 7 mainly lies in stable structure, and the integral molding is better. The wide side 7 and the narrow side 6 of the base 3 are spaced, the design of the spacing is the requirement of stamping and bending, and the elastic clamping and the reduction of the obstruction during the installation are facilitated. The base 3 is formed by stamping and bending, the stamping and bending can reduce working procedures, and the production and the assembly are convenient and rapid.
