Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment, in particular to a dustproof contactor. Background Art

[0002] Contactors are widely used switching devices, mainly used for frequent connection or disconnection of AC main circuits and large-capacity control circuits. Contactors can be divided into AC contactors and DC contactors according to the type of controlled current. Commonly used AC contactors can be divided into electromagnetic and vacuum contactors. Electromagnetic AC contactors are mainly composed of electromagnetic systems and contact systems, relying on the attraction of the moving and static iron cores in the electromagnetic system under the action of electromagnetic force to drive the closing of the moving and static contacts.

[0003] However, current contactors, such as the contactor with patent number CN110299266A, have a gap between the top contact support and the base. Under harsh operating environments, dust and other foreign matter can easily fall into the core and contact surface, causing the following situations: 1. When dust falls on the core pole surface, it increases leakage flux and generates electromagnetic noise; 2. When dust falls on the contact surface, it causes excessive temperature rise of the terminal, affecting the electrical life. Utility Model Content

[0004] The purpose of the utility model is to provide a dustproof contactor to solve the problems raised in the above background technology.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a dustproof contactor, comprising a contactor body, a panel installed on the contactor body, and a dustproof cover is also provided on the outer side of the panel; the dustproof cover is connected to a first hook groove on the contactor body through a first hook body; a second hook body is also provided on the dustproof cover, and the second hook body is adaptively connected to a second hook groove provided on the panel.

[0006] As a preferred technical solution of the utility model: a side of the dust cover facing the panel is further provided with a protrusion, and is attached to the panel via the protrusion.

[0007] As a preferred technical solution of the present utility model: the number of the second hooks is two, and they are arranged side by side in the dust cover.

[0008] As a preferred technical solution of the utility model: the first hook and the two second hooks are arranged in a triangle shape inside the dust cover.

[0009] By adopting the above technical scheme, the beneficial effects of the utility model are: 1. The dust cover is covered on the panel, so that the dust cover can be reliably fixed and at the same time, the dust cover can be covered on the middle part of the panel to prevent dust from entering the inside of the contactor body through the middle part of the panel, so as to solve the influence of dust on the operation of the contactor.

[0010] 2. Since the dust cover is simply connected to the panel and the contactor body, and the dust cover has a simple structure, the mold precision required for the production of the dust cover and the equipment is relatively low, which is convenient for manufacturing;

[0011] 3. The dust cover adopts a push-type installation method, which is not only simple to install and easy to operate, but also has high stability after installation and will not loosen or fall off. It also has the advantages of excellent dustproof effect and beautiful appearance. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] 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.

[0019] See also Figure 1-5 The utility model provides an embodiment: a dustproof contactor, comprising a contactor body 1, a panel 2 installed on the contactor body 1, and a dust cover 3 is also provided on the outer side of the panel 2; the dust cover 3 is connected to the first hook groove 6 on the contactor body 1 through a first hook body 4; the dust cover 3 is also provided with a second hook body 5, and the second hook body 5 is adaptively connected with the second hook groove 7 provided on the panel 2.

[0020] In summary, the dust cover 3 is covered on the panel 2, so that the dust cover 3 can be reliably fixed and at the same time, the dust cover 3 can be covered on the middle part of the panel 2 to prevent dust from entering the inside of the contactor body 1 through the middle part of the panel 2, so as to solve the influence of dust on the operation of the contactor.

[0021] At the same time, since the dust cover 3 is simply connected to the panel 2 and the contactor body 1, and the structure of the dust cover 3 is simple, the mold precision required for the production of the dust cover 3 and the equipment is relatively low, which is convenient for manufacturing;

[0022] Furthermore, since the dust cover 3 is installed in a push-type manner, it is not only simple to install and easy to operate, but also has high stability after installation and will not become loose or fall off. In addition, it has the advantages of excellent dustproof effect and beautiful appearance.

[0023] Furthermore, since the dust cover 3 is provided with a protrusion 8 on the side facing the panel 2, and the protrusion 8 is fitted on the panel 2, the protrusion 8 can be used to fit the panel 2 to further prevent dust from entering the contactor body 1; in addition, during specific use, the dust cover 3 can also be made of elastic plastic to enhance the sealing ability of the protrusion 8 to the gap between the dust cover 3 and the panel 2.

[0024] On the basis of the above solution, since there are two second hooks 5 and they are arranged side by side in the dust cover 3, the connection strength between the dust cover 3 and the panel 2 and the reliability after connection can be improved by increasing the number of second hooks 5.

[0025] Furthermore, since the first hook 4 and the two second hooks 5 are arranged in a triangle inside the dust cover 3, the dust cover 3 can be reliably and stably connected to the panel 2 and the contactor body 1 after installation, so as to improve the stability of the dust cover 3 after connection. In addition, the first hook 4 passes through the panel 2 and is connected to the first hook groove 6 on the contactor body 1. Therefore, when the dust cover 3 is installed, it is connected to both the panel 2 and the contactor body 1, so the stability of the dust cover 3 after fixing can be greatly enhanced.

[0026] In summary, the dust cover 3 is set to a square structure, and a protrusion 8 is set along the side of the dust cover 3 facing the panel 2 to reduce the gap between the panel 2 and the dust cover 3. At the same time, the first hook body 4 is connected to the first hook groove 6, and the second hook body 5 is connected to the second hook groove 7 to improve the stability of the dust cover 3 after installation to prevent the dust cover 3 from falling due to shock. At the same time, the dust cover 3 is positioned by the cooperation of the hook body and the hook groove to prevent the dust cover 3 from sliding on the contactor body 1.

[0027] Based on this, the device improves the dustproof effect while not affecting the main structure of the contactor body 1.
