Abstract
Description
Technical Field
[0001] This utility model relates to the field of voltage regulators, and more specifically, to a small voltage regulator. Background Technology
[0002] A voltage regulator is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are a primary coil, a secondary coil, and an iron core (magnetic core). Its main functions include voltage transformation, current transformation, impedance transformation, isolation, and voltage stabilization (magnetic saturation transformer). Based on the application environment, it can be divided into small and medium-to-large types.
[0003] Small voltage regulators typically consist of a base and a mounting cover. Since most mounting covers are U-shaped, during production and installation, the mounting cover is usually placed directly on the base from above or from the side and then bolted on. However, existing small voltage regulators do not have a limiting structure for the mounting cover, which makes it easy for it to become misaligned during production, requiring constant adjustments. In addition, fixing it requires the operator to hold it with one hand, which is quite cumbersome. Utility Model Content

[0019] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.
[0021] Reference Figures 1 to 5 The embodiments of this utility model will be further described below.
[0022] A small voltage regulator includes a base 1 and a fixing cover 2. Mounting panels 12 extend from both ends of the base 1. The fixing cover 2 is fixed to the base 1 and forms mounting cavities for mounting parts. Fixing edges 13 are bent on both sides of the mounting panels 12. Locking holes 3 are provided on both the fixing edges 13 and the base 1. Snap-fit protrusions 32 are formed on both the fixing edges 13 and the base 1 at the locking holes 3. These snap-fit protrusions 32 protrude rearward from the fixing edges 13 and the base 1 to form a frustum shape (see attached diagram). Figure 5 When the fixed cover 2 moves toward the base 1, the fixed edge 13 and the snap-fit protrusion 32 on the base 1 cooperate to form a preliminary positioning, so that the product can be installed without personnel support and is not easy to deviate. The fixed edge 13 or one side of the base 1 is bent to form a limiting gap 4. In actual production, the limiting gap 4 can be formed by bending the fixed edge 13 or the base 1 according to the length of the outer side of the fixed cover 2 (if the outer side of the fixed cover 2 extends to the base, it can be bent by the base 1, and vice versa). This structure can be integrally formed with the product, and then it can be achieved simply, conveniently and practically by bending. The fixed edge 13 is also provided with a sealing edge 41 on one side of the sealing limiting gap 4. When installing the fixed cover 2, the fixed cover 2 can be inserted into the limiting gap 4 and cooperate with the snap-fit protrusion 32 to complete the pre-positioning of the product and facilitate the assembly of the product.
[0023] Reference Figure 4 The fixed edge 13 is also provided with an elastic connecting end 42 that bends toward the limiting gap 4. The limiting gap 4 is also provided with an elastic connecting end 42, which has a certain elasticity. When the edge of the fixed cover 2 is inserted into the limiting gap 4, it can press against the fixed cover 2 under the action of elasticity to prevent it from moving. At the same time, the elastic connecting end 42 and the fixed edge 13 can be integrally formed during production and subsequently formed by bending. The structure is simple but practical and convenient.
[0024] Reference Figure 1 , 2A panel support 5 is fixed between the two mounting panels 12. Both the panel support 5 and the mounting panel 12 are provided with locking holes 3. The panel support 5 is provided with a number of mounting slots 52. In actual use, the number of slots can be opened according to the needs. The fixing cover 2 is provided with an opening slot 53 that matches it. The mounting slot 52 is provided with a fixing component for fixing parts, such as circuit breakers, switches and other parts.
[0025] Reference Figure 3 The fastener includes a snap-fit bracket 6, which includes a limiting end face 61 and an elastic edge 62 extending from the limiting end face 61. An elastic segment 63 is provided on the middle part of the elastic edge 62, and the elastic segment 63 is movable within the elastic edge 62. A snap-fit part 64 protrudes outward from the elastic segment 63, and a guide slope 66 is formed on the snap-fit part 64. During installation, the snap-fit bracket 6 can be inserted into the slot. The guide slope 66 cooperates with the edge of the slot to drive the elastic segment 63 to bend. After the snap-fit part 64 passes through the slot, it resets. Then, it cooperates with the limiting end face 61 to fix the snap-fit bracket 6 in the slot. Then, products such as circuit breakers can be inserted into the snap-fit bracket 6, and the limiting part 43 at the lower end of the snap-fit bracket 6 will support the product.
[0026] Reference Figure 2 The fastener includes a fixing hole, and the parts are connected to the panel support 5 by bolts and threads. Different fasteners are used to install different parts.
[0027] Reference Figure 2 The panel support 5 has a recessed limiting opening 71, which gradually increases in size from the panel support 5 toward the outside. The mounting panel 12 has a protruding limiting post 72, which is rectangular. When the mounting panel 12 is supported, the panel support 5 is moved toward the base 1, and the limiting opening 71 guides the limiting post 72 into the limiting opening 71. The rectangular limiting post 72 makes the panel support 5 stable when it is not fixed, which facilitates the installation of bolts.
[0028] This specific embodiment is merely an explanation of the present utility model and is not intended to limit the present utility model. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but as long as they are within the scope of the claims of the present utility model, they are protected by patent law.
