[0048] Typical embodiments that embody the features and advantages of the present disclosure will be described in detail in the following description. It should be understood that the present disclosure can have various changes in different embodiments without departing from the scope of the present disclosure, and the descriptions and drawings therein are essentially for illustrative purposes rather than for limiting the present disclosure.

[0049] In the following description of different exemplary embodiments of the present disclosure, reference is made to the accompanying drawings, which form a part of the present disclosure and in which different exemplary structures, systems and steps that can implement multiple aspects of the present disclosure are shown by way of example. It should be understood that other specific schemes of components, structures, exemplary devices, systems and steps can be used, and structural and functional modifications can be made without departing from the scope of the present disclosure. Moreover, although the terms "above", "between", "within", etc. may be used in this specification to describe different exemplary features and elements of the present disclosure, these terms are used herein only for convenience, such as according to the direction of the examples described in the accompanying drawings. Nothing in this specification should be construed as requiring a specific three-dimensional orientation of the structure to fall within the scope of the present disclosure.

[0050] See also Figure 1 and Figure 2 , which respectively and representatively show the three-dimensional structural schematic diagrams of the relay proposed in the present disclosure in two different viewing angles in an exemplary embodiment, the two different viewing angles are, for example, a front view and a rear view. In this exemplary embodiment, the relay proposed in the present disclosure is described by taking a relay including two main static contacts 410 as an example. It is easy for those skilled in the art to understand that in order to apply the relevant design of the present disclosure to other types of relays, various modifications, additions, substitutions, deletions or other changes are made to the specific embodiments described below, and these changes are still within the scope of the principle of the relay proposed in the present disclosure.

[0051] like Figure 1 and Figure 2As shown, in one embodiment of the present disclosure, the relay proposed in the present disclosure includes a housing 100, a main contact assembly, an auxiliary contact assembly, a magnetic circuit part and a mounting portion 200. The main contact assembly is partially arranged in the housing 100, and the main contact assembly includes a main static contact 410, which is the high-voltage side lead-out structure of the relay. The auxiliary contact assembly is partially arranged in the housing 100, and the auxiliary contact assembly includes an auxiliary lead-out structure 320. The magnetic circuit part is partially arranged in the housing 100, and the magnetic circuit part includes a coil assembly 500, and the coil assembly 500 includes a coil, and the coil is connected to the coil lead-out structure 310. The mounting portion 200 is arranged on the outer surface of the housing 100. On this basis, the coil lead-out structure 310 and the auxiliary lead-out structure 320 are led out from the same side of the housing 100, and the coil lead-out structure 310 and the auxiliary lead-out structure 320 are the low-voltage side lead-out structure 300 of the relay. The main static contact 410 and the low-voltage side lead-out structure 300 are led out from different sides of the housing 100, respectively. The mounting portion 200 and the lead-out portion of the main static contact 410 and the lead-out portion of the low-voltage side lead-out structure 300 are respectively located on different sides of the housing 100. The so-called lead-out portion refers to the portion of the main static contact 410, the coil lead-out structure 310 and the auxiliary lead-out structure 320 that are led out of the housing 100. Through the above structural design, the present disclosure arranges the mounting portion 200 of the relay and the lead-out portion of the high-voltage side lead-out structure and the lead-out portion of the low-voltage side lead-out structure 300 on different sides of the housing 100, thereby avoiding mutual interference between the installation of the housing 100 and the connection of the high and low voltage sides, and ensuring the overall installation effect of the relay and the effective connection of the high and low voltage side lead-out structures with external devices.

[0052] like Figure 1 and Figure 2 As shown, in one embodiment of the present disclosure, the housing 100 is a square shell structure, and the housing 100 has two first walls 101, two second walls 102 and two third walls 103, the two first walls 101 are arranged at intervals along the first direction X, the two second walls 102 are arranged at intervals along the second direction Y, the second direction Y is perpendicular to the first direction X, and the two third walls 103 are arranged at intervals along the third direction Z, the third direction Z is perpendicular to the first direction X and perpendicular to the second direction Y. On this basis, at least one first wall 101 is provided with a mounting portion 200. That is, in some embodiments of the present disclosure, one first wall 101 is provided with a mounting portion 200, and the other first wall 101 is not provided with a mounting portion 200, or, in other embodiments of the present disclosure, both first walls 101 can be provided with a mounting portion 200, which can be flexibly selected according to the installation requirements of the relay.

[0053] like Figure 1 and Figure 2As shown, based on the structural design that the housing 100 includes a first wall 101, a second wall 102 and a third wall 103 and the mounting portion 200 is disposed on the first wall 101, in one embodiment of the present disclosure, the relay proposed in the present disclosure may include two mounting portions 200, and the two mounting portions 200 are respectively disposed on the outer surfaces of the two first walls 101 of the housing 100. Through the above structural design, the present disclosure can further improve the overall installation effect of the relay by using two mounting portions 200. In some embodiments, for any first wall 101, two or more mounting portions 200 may also be disposed on its outer surface, and when the outer surfaces of the two first walls 101 are both provided with mounting portions 200, the number of mounting portions 200 disposed on the two first walls 101 may also be unequal, and are not limited to this embodiment.

[0054] like Figure 1 and Figure 2 As shown, in one embodiment of the present disclosure, the coil lead-out structure 310 and the auxiliary lead-out structure 320 (i.e., the low-voltage side lead-out structure 300) can be led out from one of the second walls 102 (e.g., the "bottom wall" not shown in the drawings because of the viewing angle being blocked). Furthermore, the main static contact 410 can be led out from another of the second walls 102 (e.g., the "top wall" shown in the drawings).

[0055] like Figure 1 and Figure 2 As shown, based on the structural design that the low-voltage side lead-out structure 300 and the main static contact 410 are respectively led out by the two second walls 101, in one embodiment of the present disclosure, along the second direction Y, the above-mentioned two mounting portions 200 can be staggered, that is, for example, the two mounting portions 200 shown in the figure adopt a "one high and one low" arrangement. Through the above structural design, the present disclosure can reduce the installation space of the relay, thereby achieving the purpose of reducing the product size.

[0056] like Figure 1 and Figure 2 As shown, based on the structural design that the low-voltage side lead-out structure 300 and the main static contact 410 are respectively led out by two second walls 101, in one embodiment of the present disclosure, along the third direction Z, the mounting portion 200 can be located in the middle area of ​​the outer surface of the first wall 101, and the so-called "middle area" refers to the remaining area except the two ends in the third direction Z.

[0057] See also Figure 3 and Figure 4 , Figure 3 and Figure 4 Schematic diagrams of the three-dimensional structure of the relay proposed in the present disclosure in another exemplary embodiment at two different viewing angles are respectively representatively shown, the two different viewing angles being, for example, a front view and a rear view.

[0058] Different from Figure 1 and Figure 2 In the embodiment shown, the main static contact 410 and the low-voltage side lead-out structure 300 are respectively led out from the two second walls 102 of the housing 100. Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, the main static contact 410 can be led out from one of the second walls 102, and the coil lead-out structure 310 and the auxiliary lead-out structure 320 (i.e., the low-voltage side lead-out structure 300) can be led out from one of the third walls 103. In other words, the high-voltage side lead-out structure and the low-voltage side lead-out structure 300 of the relay are led out from different perpendicular walls of the housing 100, respectively.

[0059] like Figure 3 and Figure 4 As shown, on this basis, along the third direction Z, the mounting portion 200 can be arranged close to a third wall 103 for the low-pressure side lead-out structure 300 to be led out. In other words, in the third direction Z, the distance between the mounting portion 200 and a third wall 103 for the low-pressure side lead-out structure 300 to be led out is smaller than the distance between the mounting portion 200 and another third wall 103. Through the above structural design, the present disclosure can facilitate the same-direction assembly of the mounting portion 200 and the low-pressure side lead-out structure 300.

[0060] like Figure 3 and Figure 4 As shown, based on the structural design that the main static contact 410 is led out from the second wall 102 and the low-voltage side lead-out structure 300 is led out from the third wall 103, in one embodiment of the present disclosure, along the second direction Y, the mounting portion 200 can be located in the middle area of ​​the outer surface of the first wall 101, and the so-called "middle area" refers to the remaining area except the two ends in the second direction Y.

[0061] like Figure 3 As shown, based on the structural design that the main static contact 410 is led out from the second wall 102 and the low-voltage side lead-out structure 300 is led out from the third wall 103, in one embodiment of the present disclosure, the relay may include two mounting portions 200, which are respectively arranged on the outer surfaces of the two first walls 101 of the housing 100. On this basis, along the second direction Y, the positions of the two mounting portions 200 correspond.

[0062] See also Figure 5 and Figure 6 , Figure 5 A three-dimensional structural schematic diagram of a relay proposed in the present disclosure in another exemplary embodiment is representatively shown in FIG. Figure 6 A representative example is shown in Figure 5 A three-dimensional exploded schematic diagram of a relay is shown.

[0063] like Figure 5 and Figure 6 As shown, in one embodiment of the present disclosure, still taking the structural design that the main static contact 410 is led out from the second wall 102 and the low-voltage side lead-out structure 300 is led out from the third wall 103 as an example, the housing 100 may further include a first shell 110 and a second shell 120. Specifically, the first shell 110 is a hood-like structure and has an end wall 1111 and a side wall 1112, the end wall 1111 is an end wall surface of the first shell 110 in the second direction Y, and the end wall 1111 is the second wall 102 for leading out the main static contact 410, and the other end of the first shell 110 in the second direction Y is an opening. The second shell 120 is arranged at the opening of the first shell 110. On this basis, the first shell 110 includes a body 111 and an assembly plate 112, the body 111 is provided with a notch 1113 on the side wall 1112, the notch 1113 is connected to the opening of the first shell 110, and the assembly plate 112 is arranged in the notch 1113 and serves as a part of the side wall 1112. Among them, the coil lead-out structure 310 and the auxiliary lead-out structure 320 (i.e., the low-voltage side lead-out structure 300) can be assembled on the assembly plate 112, and the low-voltage side lead-out structure 300 is led out by the assembly plate 112. Through the above structural design, the present disclosure can utilize the assembly plate 112 relatively independent of the body 111 to assemble with the low-voltage side lead-out structure 300, and then assemble the assembled structure as a whole with the body 111 to form the first shell 110, which is convenient for the assembly and lead-out of the low-voltage side lead-out structure 300 and the housing 100, which is conducive to reducing the difficulty of assembly and improving the assembly efficiency. Moreover, since the lead-out direction (for example, the third direction Z) of the low-pressure side lead-out structure 300 is different from the installation direction (for example, the second direction Y) of the first shell 110, the utility model can further utilize the design of the assembly plate 112 to avoid the interference problem that may arise when the above-mentioned lead-out direction is different from the installation direction, and will not change the overall structure of the first shell 110.

[0064] It should be noted that in this specification, the lead-out direction of each lead-out structure specifically refers to the extension direction of the lead-out part of the lead-out structure, that is, the extension direction of the part of the lead-out structure leading out of the shell, and does not limit the shape and arrangement direction of the lead-out structure inside the shell.

[0065] It should be noted that, based on the design that the housing 100 includes the first housing 110, in one embodiment of the present disclosure, the first housing 110 may be an integrated cover-like structure, that is, the end wall 1111 and the side wall 1112 of the first housing 110 are both integrated structures. In some embodiments, the first housing 110 may also be formed by connecting and assembling a plurality of relatively independent parts (e.g., a plurality of panels). Figure 1 and Figure 2 In the illustrated embodiment, the housing 100 may also be formed by connecting and assembling a plurality of relatively independent parts (eg, a plurality of panels).

[0066] It should be noted that, in various possible implementations consistent with the design concept of the present disclosure, no matter whether only one first wall 101 of the housing 100 is provided with the mounting portion 200 or both first walls 101 are provided with the mounting portion 200, and no matter whether the housing 100 is divided into the first shell 110 and the second shell 120, the main static contact 410 of the relay can be led out from the other second wall 102 or the third wall 103. In other words, on the basis that the mounting portion 200 and the low-voltage side lead-out structure 300 are located on different perpendicular walls of the housing 100, the main static contact 410 of the relay can be further led out from other walls different from the above-mentioned walls.

[0067] See also Figure 7 and Figure 8 , Figure 7 and Figure 8 Schematic diagrams of the three-dimensional structure of the relay proposed in the present disclosure in another exemplary embodiment at two different viewing angles are respectively representatively shown, the two different viewing angles being, for example, a front view and a rear view.

[0068] Different from Figures 1 to 6 In each embodiment shown, a relay is used which includes two main static contacts 410. Figure 7 and Figure 8 As shown, in one embodiment of the present disclosure, the relay proposed in the present disclosure includes four main static contacts 410. For example, the relay may include two functional modules, which are jointly arranged in the housing 100, each functional module includes a main contact component, a magnetic circuit part and an auxiliary contact component, each main contact component includes two main static contacts 410, each magnetic circuit part is connected to two coil lead-out structures 310, and each auxiliary contact component includes two auxiliary lead-out structures 320. On this basis, all the main static contacts 410 of each functional module can be led out from the same wall of the housing 100, and all the coil lead-out structures 310 and all the auxiliary lead-out structures 320 of each functional module can be led out from another same wall of the housing 100, so as to achieve the desired effect. Figure 7 and Figure 8 For example, the housing 100 includes two second walls 102 , each main static contact 410 is led out from one second wall 102 , and each coil lead-out structure 310 and auxiliary lead-out structure 320 is led out from another second wall 102 .

[0069] like Figures 1 to 8 As shown, in one embodiment of the present disclosure, the main contact assembly includes two main static contacts 410, and the main contact assembly also includes an active contact sheet. Both ends of the active contact sheet are in contact with or separated from the two main static contacts 410 respectively.

[0070] It should be noted that the relays shown in the drawings and described in this specification are only a few examples of the many types of relays that can adopt the principles of the present disclosure. It should be clearly understood that the principles of the present disclosure are by no means limited to any details of the relays shown in the drawings or described in this specification or any components of the relays.

[0071] In summary, the relay proposed in the present invention includes a housing 100, a mounting portion 200, a main static contact 410 and a low-voltage side lead-out structure 300; the low-voltage side lead-out structure 300 includes a coil lead-out structure 310 and an auxiliary lead-out structure 320, the coil lead-out structure 310 and the auxiliary lead-out structure 320 are led out from the same side of the housing 100, the main static contact 410 and the low-voltage side lead-out structure 300 are respectively led out from different sides of the housing 100, the mounting portion 200 is arranged on the outer surface of the housing 100, and is located on different sides of the housing as the lead-out portion of the main static contact 410 and the lead-out portion of the low-voltage side lead-out structure 300. Through the above-mentioned structural design, the present invention arranges the installation part 200 of the relay and the lead-out part of the high-voltage side lead-out structure and the lead-out part of the low-voltage side lead-out structure 300 on different sides of the shell 100, thereby avoiding mutual interference between the installation of the shell 100 and the high- and low-voltage side connections, thereby ensuring the overall installation effect of the relay and the effective connection between the high- and low-voltage side lead-out structures and external equipment.
