[0002] A relay is a widely used electrical control component. When the input quantity to the relay reaches a specified requirement, the relay causes a predetermined step change in the controlled quantity in the electrical output circuit. Relays are commonly used in automatic control circuits, serving functions such as automatic adjustment, safety protection, and circuit switching.

[0003] Existing high-voltage DC relays are typically single-coil driven, single-unit relays containing only one relay unit within the housing. While single-unit relays can be used in combination, this requires double installation when using two relays. Furthermore, existing combined relays occupy a large space and have low integration, increasing both material and installation costs, and are not conducive to saving space. Utility Model Content

[0033] It should be understood that the terminology used in this specification is for describing specific embodiments only and is not intended to limit this disclosure. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0034] In view of the above-mentioned deficiencies in the prior art, this disclosure provides a dual-drive dual-gang relay, and the embodiments for implementing this disclosure will be described in detail below with reference to the accompanying drawings.

[0035] like Figures 1 to 9 As shown, an embodiment of this disclosure provides a dual-drive, dual-gang relay, which includes a housing and a relay assembly 3. The housing is made of an insulating material and defines an inner cavity. Specifically, the housing may include a first housing assembly 1 and a second housing assembly 2. The first housing assembly 1 may include a partition 12 made of an insulating material (see...). Figure 7 The partition 12 can divide the interior cavity defined by the housing into a first chamber and a second chamber. The first chamber and the second chamber may have the same shape and volume or different shapes. The partition 12 may be integrally formed with the first housing assembly 1. Alternatively, the partition 12 may be detachably connected to the first housing assembly 1 to facilitate the assembly and disassembly of the partition 12.

[0036] The relay assembly 3 is disposed within an inner cavity defined by the housing. The relay assembly 3 includes a first relay unit 31 and a second relay unit 32. The first relay unit 31 and the second relay unit 32 can be relays of the same structure and type, or relays of different structures and / or types. The first relay unit 31 and the second relay unit 32 can be connected in parallel or in series according to actual usage requirements. For example, when a larger resistance is required, the first relay unit 31 and the second relay unit 32 can be connected in series, in which case the total resistance is equivalent to twice that of a single relay unit. When a smaller resistance is required, the first relay unit 31 and the second relay unit 32 can be connected in parallel, in which case the total resistance is equivalent to half that of a single relay unit.

[0037] Specifically, when the internal cavity defined by the housing is divided into a first chamber and a second chamber by the partition 12, the first relay unit 31 can be disposed in the first chamber, and the second relay unit 32 can be disposed in the second chamber. The first relay unit 31 includes a first frame, a first drive coil, and first output terminals 311 and 312 (see...). Figure 2 The second relay unit 32 includes a second frame, a second drive coil, and second output terminals 321 and 322 (see...). Figure 2 The shape of the first frame of the first relay unit 31 can be configured to correspond to the shape of the first chamber, and the shape of the second frame of the second relay unit 32 can be configured to correspond to the shape of the second chamber. Through the above configuration, the first relay unit 31 and the second relay unit 32 can not only effectively utilize the internal space of the housing, but also avoid mutual interference between the magnetic fields generated by the first relay unit 31 and the second relay unit 32 during use, thereby improving overall stability.

[0038] Preferably, the first relay unit 31 and the second relay unit 32 have the same structure and are arranged side by side. That is, the first relay unit 31 and the second relay unit 32 are relays with the same structure and can be arranged side by side in the inner cavity of the housing. When the first relay unit 31 and the second relay unit 32 have the same structure, the first chamber and the second chamber can also have the same structure, thereby achieving the purpose of matching the first relay unit 31 and the second relay unit 32. By arranging the first relay unit 31 and the second relay unit 32 side by side, the structure of the dual-drive dual-gang relay according to this disclosure can be made more compact, and the overall size is smaller.

[0039] Preferably, such as Figure 7As shown, support plates 13 can be provided on one or both sides of the partition 12 to support and stabilize the partition 12. Additionally, reinforcing ribs 14 can be provided on the inner wall of the first housing assembly 1. The provision of support plates 13 and reinforcing ribs 14 not only ensures that the first housing assembly 1 better matches the first frame of the first relay unit 31 and the second frame of the second relay unit 32, but also reserves appropriate space for the overall housing size so that the housing shape can match relay units of different sizes.

[0040] More preferably, the first housing assembly 1 may include one or more mounting holes to facilitate the mounting of a dual-drive, dual-gang relay. For example... Figure 2 , Figure 6 and Figure 7 As shown, the first housing assembly 1 includes three mounting holes 11A, 11B, and 11C. However, those skilled in the art will understand that, depending on actual installation requirements, the first housing assembly 1 may include fewer or more than three mounting holes. Figure 8 and Figure 8A As shown, the mounting holes can be equipped with guide mechanisms 15 so that each mounting hole can play a guiding role when actually installing the dual-drive dual-gang relay, thereby avoiding the risk of misalignment during the installation process and facilitating installation.

[0041] Furthermore, the dual-drive, dual-gang relay according to this disclosure also includes a common input terminal, which comprises a first input connection portion and a second input connection portion. The first drive coil of the first relay unit 31 is electrically connected to the first input connection portion, and the second drive coil of the second relay unit 32 is electrically connected to the second input connection portion. Specifically, the common input terminal may be in the form of a plug-in cable 33 disposed at the bottom of the relay assembly 3, as shown in the accompanying drawings. Preferably, the plug-in cable 33 may include four leads, wherein two leads serve as the first input connection portion electrically connected to the first drive coil of the first relay unit 31, and the other two leads serve as the second input connection portion electrically connected to the second drive coil of the second relay unit 32. By setting the common input terminal to be shared by the first relay unit 31 and the second relay unit 32, the structure is further simplified, and the integration and space utilization are improved.

[0042] like Figure 9 As shown, the second housing assembly 2 of the dual-drive, dual-gang relay according to this disclosure includes a first mounting portion and a second mounting portion. A first relay unit 31 is mounted on the first mounting portion, and a second relay unit 32 is mounted on the second mounting portion. The first mounting portion may include a plurality of protrusions 21 (in... Figure 9 The image shows four protrusions 21), and the second mounting portion may also include multiple protrusions 22 (in the image). Figure 9Four protrusions 22 are shown to facilitate the installation and positioning of the first relay unit 31 and the second relay unit 32. Although in Figure 9 The first and second mounting portions shown both include four protrusions; however, those skilled in the art should understand that, depending on actual installation requirements, the first and second mounting portions may include fewer or more than four protrusions.

[0043] When assembling the dual-drive, dual-gang relay according to this disclosure, adhesive is first applied to the second housing assembly 2, then the relay assembly including the first relay unit 31 and the second relay unit 32 is placed and secured, and finally the first housing assembly 1 is closed to complete the assembly. The first housing assembly 1 and the second housing assembly 2 can be joined together, for example, by means of snap-fit ​​fastening.

[0044] Compared with existing relays, the dual-drive dual-gang relays described in this disclosure not only improve integration and space utilization, but also enable the installation of two relay units at once, thereby reducing repeated installations and lowering costs.

[0045] Although this disclosure has been described with reference to exemplary embodiments, it should be understood that this disclosure is not limited to the exemplary embodiments described above. Various variations and modifications can be made to the exemplary embodiments described above without departing from the scope of this disclosure. The scope of the appended claims should be accorded the broadest interpretation so as to include all such variations and modifications, as well as equivalent structures and functions.
