Description

Technical Field

[0001] The utility model relates to the technical field of AC contactors, in particular to an electromagnetic mechanism of an AC contactor. Background Art

[0002] For example, the prior art with patent number: CN204155860U has the following general scheme: the electromagnetic system includes a rectangular box, a coil arranged in the rectangular box, a static iron core mounted on the rectangular box at the corresponding moving iron core, a short square box installed on the rectangular box at one side of the corresponding static iron core, and a circuit board arranged in the short square box. Blocks are arranged on the outer walls on both sides of the short square box, and corresponding card holes are arranged on the rectangular box at the corresponding card blocks. The card blocks are mounted in the card holes to form a snap connection between the short square box and the rectangular box. It can be seen from this that the installation method of the electromagnetic mechanism is relatively complicated, and using a rectangular box body to accommodate the electromagnetic mechanism is not convenient for disassembly of the electromagnetic mechanism nor for heat dissipation of the electromagnetic mechanism.

Based on this, the utility model can realize the reliable fixation of the electromagnetic mechanism body while facilitating the disassembly of the electromagnetic mechanism body, thereby facilitating the replacement of the damaged electromagnetic mechanism body, thereby improving the maintenance efficiency of the electromagnetic mechanism; in particular, the electromagnetic mechanism body can be fixed to the support plate by using two limiting parts, so that the electromagnetic mechanism body, except for the bottom surface, is exposed to the outside, which is convenient for the heat dissipation of the electromagnetic mechanism body and also convenient for the disassembly of the electromagnetic mechanism body, and can also simplify the structure of the bottom plate to reduce the processing cost of the bottom plate.

[0016] Embodiments of the present utility model are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present utility model, and should not be construed as limitations on the present utility model. In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "upper surface", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on the present utility model.

[0017] See also Figure 1-4 The utility model provides an embodiment: an electromagnetic mechanism of an AC contactor, comprising a base plate 1 and an electromagnetic mechanism body 2 installed on the base plate 1; a support plate 10 is provided on the base plate 1; wherein a first limiting portion 11 is provided on one side of the support plate 10, and a second limiting portion 12 is provided on the other side of the support plate 10; when one end of the electromagnetic mechanism body 2 is inserted into the first limiting portion 11, the second limiting portion 12 is used to cover the other end of the electromagnetic mechanism body 2 and then connected to the base plate 1, so as to fix the electromagnetic mechanism body 2 on the base plate 1.

[0018] In summary, after the bottom plate 1 is pulled out from the inside of the contactor, the second limiting portion 12 is disassembled, and then the electromagnetic mechanism body 2 is slid along the support plate 10 to complete the disassembly of the electromagnetic mechanism body 2. Conversely, one end of the electromagnetic mechanism body 2 is slid along the support plate 10 toward the first limiting portion 11, and one end of the electromagnetic mechanism body 2 is inserted into the first limiting portion 11, and then the second limiting portion 12 is used to connect with the bottom plate 1, so that the electromagnetic mechanism body 2 can be simply and conveniently fixed on the bottom plate 1.

[0019] Based on this, the utility model can realize reliable fixation of the electromagnetic mechanism body 2 while facilitating the disassembly of the electromagnetic mechanism body 2, thereby facilitating replacement of the damaged electromagnetic mechanism body 2, thereby improving the maintenance efficiency of the electromagnetic mechanism;

[0020] In particular, the electromagnetic mechanism body 2 can be fixed on the support plate 10 by using two limiting parts, so that the electromagnetic mechanism body 2, except for the bottom surface, is exposed to the outside, which is convenient for the heat dissipation of the electromagnetic mechanism body 2 and the disassembly of the electromagnetic mechanism body 2, and can also simplify the structure of the bottom plate 1 to reduce the processing cost of the bottom plate 1.

[0021] Furthermore, since baffles 14 are provided on both sides of the support plate 10, and the baffles 14 are arranged in the length direction of the support plate 10, the baffles 14 can be used to fit the side of the electromagnetic mechanism body 2 to further enhance the stability of the electromagnetic mechanism body 2 after being connected to the base plate 1. At the same time, the setting of the baffles 14 can also enhance the structural strength of the support plate 10.

[0022] At the same time, since insulating pads 3 are provided at both ends of the bottom of the electromagnetic mechanism body 2, the insulating pads 3 can improve the insulation effect and also reduce the wear of the electromagnetic mechanism body 2 on the bottom plate 1 and the wear of the electromagnetic mechanism body 2 itself during the disassembly and assembly process.

[0023] In order to improve the fixing ability of the second limiting portion 12 to the electromagnetic mechanism body 2, a mounting seat 15 is further provided on the bottom plate 1, and a fastener 13 is provided through the mounting seat 15 to connect with the second limiting portion 12, so as to fix the second limiting portion 12 on the mounting seat 15. Further, the second limiting portion 12 is plate-shaped, and both ends of the second limiting portion 12 are fixed to the mounting seat 15 by the fasteners 13.

[0024] In summary, when the fastener 13 passes through the mounting seat 15 and is connected to the second limiting portion 12, the second limiting portion 12 can be reliably connected to the bottom plate 1; in addition, when the bottom surface of the bottom plate 1 faces upward, it is convenient for the user to disassemble the fastener 13, thereby facilitating the disassembly of the second limiting portion 12. The fastener 13 is preferably a bolt.

[0025] In addition, since the outer side of the support plate 10 is provided with a guide rail 16, and the middle part of the ground of the support plate 10 is provided with a protrusion 17, it is convenient to insert the support plate 10 into the contactor, and the structural strength of the support plate 10 can be enhanced.

[0026] The above is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings, but the present invention is not limited to the described embodiments. For those skilled in the art, various changes, modifications, substitutions and variations of these embodiments are made without departing from the principles and spirit of the present invention, and still fall within the scope of protection of the present invention.
