Description

Technical Field

[0001] This utility model belongs to the field of contactor technology, specifically relating to a contactor mounting structure. Background Technology

[0002] A contactor is a device that uses a coil to generate a magnetic field, which causes contacts to close, thus enabling efficient power transmission. A common contactor consists of an electromagnetic system (moving iron core, stationary iron core, and electromagnetic coil), a contact system, and an arc-extinguishing device. When the contactor's electromagnetic coil is energized, it generates a strong magnetic field, which causes the stationary iron core to attract the moving iron core, thereby actuating the contacts and closing them. When the coil is de-energized, the electromagnetic attraction disappears, the moving iron core is released by the release spring, the contacts return to their original position, and the contacts open.

[0003] In existing technologies, dust and moisture from the external environment can potentially enter the contactor, contaminating or corroding internal components such as the electromagnetic or contact mechanisms, thus reducing product performance. To prevent dust and moisture from entering the contactor, protective covers are typically installed on relevant parts of the contactor, such as auxiliary contact covers, main covers, and coil covers to protect the corresponding functional components. However, these separate protective covers are complex to assemble, and due to the need for multiple assembly steps, the gaps become too large, allowing dust to easily enter the contactor housing. Furthermore, after the contactor is installed on the electrical equipment, the side with the wiring terminals is usually exposed, making it easy for dust to enter. By moving the assembly position to the other side, where other objects will cover it, the possibility of dust entering is reduced. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of the existing contactor installation with separate protective covers and the assembly of contact supports and lower housings, and to provide a contactor installation structure. This structure uses an integrated protective cover installed above the lower housing of the contactor, completely covering the auxiliary contacts, main contacts, and terminals, thus reducing the difficulty of protective cover installation. At the same time, the assembly positions of the contact supports and the lower housing are set on different sides of the contactor terminals, further preventing dust from entering the contactor through the assembly gaps and improving safety during use.

[0005] Technical solution

[0006] To achieve the above-mentioned technical objectives, this utility model provides a contactor mounting structure, including a lower housing, a contact support mounted together with the lower housing, and a protective cover fitted onto the contact support. The assembly connection position of the contact support and the lower housing is not on the same side as the contactor's wiring terminals.

[0007] Preferably, the protective cover covers the auxiliary contacts, main contacts, and terminals of the contactor.

[0008] Preferably, the contact support is symmetrically arranged on two sides of the lower housing, on a different side from the terminal block of the contactor.

[0009] Preferably, the contact supports connection and installation with the lower housing using at least one snap-fit ​​structure.

[0010] Preferably, the protective cover is connected and installed with the contact head using a snap-fit ​​structure.

[0011] Preferably, the contact support is either integral or modular.

[0012] Preferably, the protective cover is a single piece.

[0013] Preferably, the second buckle structure includes a groove or buckle on the protective cover, and the contact support is provided with a second buckle or groove at a corresponding position to the groove or buckle.

[0014] Beneficial effects

[0015] This utility model provides a contactor mounting structure, including a lower housing and a contact support mounted together with the lower housing. The assembly connection position of the contact support and the lower housing is not on the same side as the contactor's terminals. A protective cover is fitted onto the contact support, covering the contactor's auxiliary contacts, main contacts, and terminals. The use of an integral protective cover mounted above the lower housing of the contactor completely covers the auxiliary contacts, main contacts, and terminals, reducing the difficulty of protective cover installation. Furthermore, the assembly positions of the contact support and the lower housing on different sides of the contactor's terminals further prevent dust from entering the contactor through assembly gaps, improving safety during use.

[0032] Example

[0033] To prevent dust and moisture from entering the contactor, protective covers are typically installed on relevant parts of the contactor. For example, auxiliary contact covers, main covers, and coil covers are used to protect the corresponding functional components. However, these separate protective covers are complex to assemble, and due to the need for multiple assembly steps, the gaps become too large, allowing dust to easily enter the contactor housing. Furthermore, after the contactor is installed on the electrical equipment, the side with the wiring terminals is usually exposed, making it easy for dust to enter. By moving the assembly position to the other side, where other objects will cover it, the possibility of dust entering is reduced.

[0034] As attached Figure 5 As shown in Figures 6, 7, and 8, this embodiment provides a contactor mounting structure, including a lower housing 1, a contact support 2 mounted together with the lower housing 1, and the assembly connection position 3 of the contact support 2 and the lower housing 1 not being on the same side as the contactor's wiring terminals 4. A protective cover 5 is fitted onto the structure shown in the attached figure. Figure 1 The contact support 2 shown in 2, 3, and 4 covers the auxiliary contact 6, main contact 7, and terminal 4 of the contactor.

[0035] In detail, it is as follows: (see attached document) Figure 5 As shown, the assembly connection positions 3 of the contact support 2 and the lower housing 1 are symmetrically arranged on two sides different from the terminals 4 of the contactor. The contact support 2 and the lower housing 1 are connected and installed using at least one snap-fit ​​structure 10. The snap-fit ​​structure 10 includes a conventional hook 10a and slot 10b, which enables effective installation of the contact support 2 and the lower housing 1. The contact support 2 can be integral or spliced. In this embodiment, the contact support 2 adopts the method shown in the attached diagram. Figure 1 The integrated design is shown. In this embodiment, the assembly positions 3 of the contact support 2 and the lower housing 1 are located on different sides of the contactor terminal 4, further preventing dust from entering the contactor through the assembly gap and improving safety during use.

[0036] The protective cover 5 is an integral piece. The protective cover 5 is connected and installed to the contact support 2 using a snap-fit ​​structure 9. Specifically, the snap-fit ​​structure 9 includes a snap-fit ​​on the protective cover 5, and a groove 2 on the contact support 2 at a corresponding position to the snap-fit. The snap-fit ​​is engaged in the groove 2. Alternatively, the snap-fit ​​structure 9 can include a groove 1 on the protective cover 5 (not shown in the attached diagram), and a snap-fit ​​2 on the contact support 2 at a corresponding position to the groove 1 (not shown in the attached diagram). The integral protective cover is installed above the lower housing of the contactor, completely covering the auxiliary contacts, main contacts, and terminals, reducing the difficulty of installing the protective cover and avoiding errors from multiple assembly attempts.

[0037] The contactor mounting structure provided by this utility model adopts an integral protective cover installed above the lower housing of the contactor, which completely covers the auxiliary contacts, main contacts, and wiring terminals, reducing the difficulty of installing the protective cover. At the same time, the assembly positions of the contact support and the lower housing are set on different sides of the contactor wiring terminals, further preventing dust from entering the contactor through the assembly gap and improving the safety of use.

[0038] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0039] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are specific and detailed, they should not be construed as limiting the scope of this patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
