Description

Technical Field

[0001] This utility model relates to the field of magnetic starter technology, and in particular to a magnetic starter with shock-absorbing installation. Background Technology

[0002] Magnetic starters are an important component of various water pumps, oil pumps, and fans. They are used to control the starting and stopping of AC three-phase squirrel-cage asynchronous motors and can protect the motors from overload, short circuit, and phase loss.

[0003] However, as shown in the magnetic starters disclosed in applications 202020648376.4 and 202420057295.5, current magnetic starters are generally not equipped with shock-absorbing components. This means that when installed on ships, the constant swaying of the ship will reduce the service life of the various electrical components inside the magnetic starter, thus requiring improvement.

[0015] The embodiments of the present invention are described in detail below, examples of which are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0016] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0017] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0018] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection, an electrical connection, or a connection that allows communication between them; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise explicitly limited. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] Reference Figures 1-4 According to an embodiment of the shock-absorbing magnetic starter of this utility model, it includes a base box 11 and a cover 12. The base box 11 and the cover 12 contain a combination changeover switch, an AC contactor, a thermal relay, a fuse, a button 20, an indicator light, and terminals, so that the shock-absorbing magnetic starter has the function of controlling the start and stop of the asynchronous motor, and can protect the motor from overload, short circuit and phase loss. This is a conventional setting in the prior art, and will not be described in detail here.

[0020] In addition, the front of the box cover 12 is provided with a protrusion, on which a brand 31 is fixed to mark the parameter information of the shock-absorbing magnetic starter.

[0021] The base box 11 is connected to the mounting plate 13 via a shock-absorbing component. The mounting plate 13 has two locking plates 14 that extend vertically and are distributed horizontally on its upper and lower sides, respectively. The locking plates 14 have mounting holes 15. When installing, the operator can insert fasteners through the mounting holes 15 to install the shock-absorbing magnetic starter.

[0022] The shock absorption assembly includes two steel wire shock absorbers 16, which are arranged vertically and horizontally.

[0023] By setting the steel wire shock absorber 16, the service life of the shock-absorbing magnetic starter in a vibration environment is improved, the applicability of the shock-absorbing magnetic starter is increased, and the electrical components inside the base box 11 and the cover 12 are protected.

[0024] In addition, the bottom box 11 is equipped with several stuffing boxes 17 arranged in the left and right directions on the lower side. The wires used to connect the electrical components inside the bottom box 11 and the cover 12 can pass through the stuffing boxes 17. By setting the stuffing boxes 17, the sealing performance inside the bottom box 11 and the cover 12 can be improved, and external contaminants can be prevented from entering.

[0025] In addition, the front side of the bottom box 11 is integrally formed with a hollow convex plate 18 in the shape of a square, and the box cover 12 is hinged and can be attached to the outer side of the hollow convex plate 18 to further improve the sealing performance.

[0026] In a second embodiment of the vibration-damping magnetic starter, such as Figure 4 As shown, in order to reduce the footprint of a vibration-damping magnetic starter during transportation, the locking plate 14 is designed to be hinged to the upper and lower sides of the mounting plate 13, and the locking plate 14 can be lifted during transportation.

[0027] In order to lock the shock-absorbing components of a magnetic starter with shock absorption during transportation, so as to prevent the steel wire shock absorber 16 from being damaged by large and high-frequency impacts during transportation, four abutment plates 19 are arranged in a matrix on the rear side of the base box 11. The abutment plates 19 are provided with vertically arranged threaded holes. That is, during transportation, the operator can push the locking plate 14 forward and cover the side of the abutment plate 19 at the corresponding position. Then, the fastener is passed through the mounting hole 15 and screwed into the threaded hole, so that the locking plate 14 and the base box 11 are locked together, and the steel wire shock absorber 16 is disabled.

[0028] Furthermore, in order to improve the connection strength between the base box 11 and the mounting plate 13 in this case, the left and right edges of the locking plate 14 are integrally formed with forward-extending guard plates 21. The spacing between the two guard plates 21 on one locking plate 14 is adapted to the left and right width of the abutment plate 19. When the locking plate 14 is fixed to the abutment plate 19, the guard plates 21 can be attached to the side of the abutment plate 19 to increase the strength.

[0029] The above description is only a specific embodiment of the present utility model, but the technical features of the present utility model are not limited thereto. Any changes or modifications made by those skilled in the art within the scope of the present utility model are covered by the patent scope of the present utility model.
