[0002] High voltage is the main development direction of semiconductor integrated circuits and new energy technologies. This design trend requires the testing industry and the energy management industry to provide new insulation detection solutions to match it. In this regard, as one of the most important switching devices for insulation detection, relays need to adapt to the insulation performance requirements under higher system voltages.

[0003] In the existing design of the relay module, the arrangement of the coil lead-out terminal and the load lead-out terminal of the relay makes the distance between the coil lead-out terminal on the low voltage side and the load lead-out terminal on the high voltage side close, or the coil lead-out terminal and the load lead-out terminal are arranged crosswise on the bottom plate; if it is to be used in a higher system voltage, the distance between the lead-out terminals on the high and low voltage sides is too small, that is, the creepage distance and electrical clearance between the high and low voltage sides are too small, which will lead to the failure to meet the higher insulation withstand voltage requirements; or the above-mentioned cross arrangement will cause the load end on the high voltage side to interfere with the coil end on the low voltage side. Therefore, in order to realize the application of relays in higher system voltages, it has become an important issue to be solved in the relevant field to develop a relay with better insulation withstand voltage capability.

The structure, connection mode and functional relationship of each main component of the relay module 100 proposed in the present disclosure will be described in detail below in conjunction with the above drawings.

[0070] like Figures 1 to 7 As shown, in one embodiment of the present disclosure, the relay module 100 proposed in the present disclosure includes a first base plate 110, and the first base plate 110 is provided with a coil lead terminal 131 and a load lead terminal 132, and the coil lead terminal 131 and the load lead terminal 132 are both led out by the relay module. For example, connection holes can be respectively provided on the first base plate 110 at positions corresponding to the coil lead terminal 131 and the load lead terminal 132, and the coil lead terminal 131 and the load lead terminal 132 are respectively connected to the first base plate 110 via these connection holes. In the following description in conjunction with the drawings in this specification, the cited drawings may not show the coil lead terminal 131 and the load lead terminal 132, and the coil lead terminal 131 and the load lead terminal 132 marked in the relevant drawings are actually the positions of the connection holes to which the lead terminals are connected. On this basis, the coil lead terminal 131 and the load lead terminal 132 are arranged adjacent to the two side edges of the first base plate 110 in the first direction X, and the first direction X is parallel to the first base plate 110, and the coil lead terminal 131 and the load lead terminal 132 are arranged adjacent to the two side edges of the first base plate 110 in the second direction Y, and the second direction Y is parallel to the first base plate 110 and perpendicular to the first direction X. Through the above design, the relay module proposed in the present disclosure adopts a special arrangement form for the coil lead terminal 131 and the load lead terminal 132, which can achieve the best balance of the external physical safety distance between the coil and the contact and the independent distribution on the physical space of the high and low voltage sides. The present disclosure optimizes the arrangement position of the coil lead terminal 131 and the load lead terminal 132 on the first base plate 110, thereby extending the distance between the coil lead terminal 131 and the load lead terminal 132, thereby extending the creepage distance between the high and low voltage sides of the relay module 100, and improving the insulation withstand voltage capability of the relay. In addition, the present disclosure can simplify the wiring of the circuit board (e.g., the first base plate 110 of the relay module 100 or the second base plate 200 of the switch device in the following embodiment), which is conducive to the modular design of the programmable switch device. Finally, the low-voltage side of the coil and the high-voltage side of the load (contact) can be clearly separated in the physical space on the circuit board, thereby maximally avoiding the interference caused by the cross wiring of high and low voltages.

[0071] It should be noted that, in one embodiment of the present disclosure, the first base plate 110 may be roughly rectangular, on this basis, the above-mentioned first direction X may be understood as the length direction of the rectangle, and the above-mentioned second direction Y may be understood as the width direction of the rectangle. Through the above-mentioned design, the present disclosure can further increase the creepage distance between the high and low voltage sides by utilizing the above-mentioned layout. In some embodiments, when the first base plate 110 is roughly rectangular, the first direction X may also be the width direction of the rectangle, and the second direction Y may also be the length direction of the rectangle. Furthermore, the first base plate 110 may also be in other shapes, such as a square, etc., and the above-mentioned first direction X and second direction Y may also be understood in other adaptive ways, and are not limited to this embodiment.

[0072] like Figures 5 to 7 As shown, in one embodiment of the present disclosure, the relay module 100 may be provided with at least two (for example, two shown in the drawings) coil lead terminals 131 and at least two (for example, two shown in the drawings) load lead terminals 132, and the at least two coil lead terminals 131 may be arranged at intervals along the second direction Y, and the at least two load lead terminals 132 may be arranged at intervals along the first direction X. Through the above design, the present disclosure can increase the distance between the coil lead terminal 131 and the load lead terminal 132 and the structure is compact, thereby extending the creepage distance between the high and low voltage sides of the relay module, improving the insulation withstand voltage capability of the relay, and improving the insulation performance of the high and low voltage sides of the relay module 100. In some embodiments, the relay module 100 may also include three or more coil lead terminals 131, and the relay module 100 may also include three or more load lead terminals 132, and the number of the coil lead terminals 131 and the load lead terminals 132 may be equal or unequal, and is not limited to the above embodiment.

[0073] It should be noted that if Figure 7As shown, since the coil lead-out terminal 131 and the load lead-out terminal 132 are respectively arranged adjacent to the two side edges of the first bottom plate 110 in the first direction X, accordingly, the two coil lead-out terminals 131 arranged at intervals along the second direction Y can both be arranged adjacent to one side edge (e.g., the third edge 1106) of the first bottom plate 110 in the first direction X, and one coil lead-out terminal 131 is arranged closer to one side edge (e.g., the first edge 1104) of the first bottom plate 110 in the second direction Y than the other coil lead-out terminal 131. At the same time, since the coil lead-out terminal 131 and the load lead-out terminal 132 are respectively arranged adjacent to the two side edges of the first bottom plate 110 in the second direction Y, the two load lead-out terminals 132 can both be arranged adjacent to the other side edge (e.g., the second edge 1105) of the first bottom plate 110 in the second direction Y, and one load lead-out terminal 132 is arranged closer to the other side edge (e.g., the fourth edge 1107) of the first bottom plate 110 in the first direction X than the other load lead-out terminal 132.

[0074] like Figure 7 As shown, based on the design that the relay module 100 is provided with at least two coil lead terminals 131 and at least two load lead terminals 132, in one embodiment of the present disclosure, at least one coil lead terminal 131 and at least one load lead terminal 132 can be respectively located at two corners 1101 of the first bottom plate 110, and the two corners 1101 are arranged in a diagonal form on the first bottom plate 110. Through the above design, the present disclosure can further make more space between the coil lead terminal 131 and the load lead terminal 132.

[0075] like Figures 1 to 7As shown, in one embodiment of the present disclosure, the relay module 100 proposed in the present disclosure includes a relay monomer 120. The relay monomer 120 is arranged on a side surface of the first base plate 110. Among them, the low-voltage side of the relay monomer 120 is connected to a coil connection terminal 121, and each relay monomer 120 may include at least two (for example, two shown in the figure) coil connection terminals 121 arranged at least at intervals. The high-voltage side of the relay monomer 120 is connected to a load connection terminal 122, and each relay monomer 120 may include at least two (for example, two shown in the figure) load connection terminals 122 arranged at least at intervals. For example, the high-voltage side and the low-voltage side of the relay monomer 120 are the two sides thereof in the second direction Y, and for one relay monomer 120, the two load connection terminals 122 provided on the high-voltage side thereof are arranged at intervals along the first direction X, and the load connection terminals 122 of each relay monomer 120 are located between the two load lead terminals 132 of the relay module and are connected in series, and the two coil connection terminals 121 provided on the low-voltage side of the relay monomer 120 are also arranged at intervals along the first direction, and the coil connection terminals 121 of each relay monomer 120 are respectively connected in parallel with the two coil lead terminals 131. The coil connection terminals 121 of the relay monomer 120 are connected to the coil lead terminals 131 of the relay module 100 via the wiring of the first base plate 110, and the load connection terminals 122 of the relay monomer 120 are connected to the load lead terminals 132 of the relay module 100 via the wiring of the first base plate 110. Through the above design, since the present disclosure optimizes the arrangement positions of the coil lead-out terminal 131 and the load lead-out terminal 132 on the first base plate 110 , the relay module 100 leaves sufficient arrangement space for the isolation structure on the first base plate 110 .

[0076] It should be noted that, in this embodiment, the relay module 100 includes the first base plate 110 and the relay monomer 120 disposed on the first base plate 110. It should be understood that, in some embodiments, the relay module 100 proposed in the present disclosure may also include the first base plate 110 without including the relay monomer 120, and is not limited to this embodiment.

[0077] like Figures 5 to 7 As shown, in one embodiment of the present disclosure, the first base plate 110 may also be provided with an isolation structure, which is used to achieve isolation between the coil drive side (i.e., the low-voltage side) and the contact load side (i.e., the high-voltage side) of the relay module 100 on the first base plate 110, and can also achieve isolation between the relay modules 100.

[0078] like Figures 5 to 7As shown, in one embodiment of the present disclosure, the first base plate 110 has a first area 1102 and a second area 1103 arranged along the first direction X, and the relay monomer 120 is only provided in the first area 1102. On this basis, the coil lead terminal 131 can be connected to the second area 1103 of the first base plate 110, and the load lead terminal 132 can be connected to the first area 1102 of the first base plate 110.

[0079] like Figures 5 to 7 As shown, based on the design that the first bottom plate 110 has the first area 1102 and the second area 1103, in one embodiment of the present disclosure, the isolation structure may include a first isolation groove 111, the first isolation groove 111 penetrates the first bottom plate 110 along the thickness direction, and the first isolation groove 111 is located between the first area 1102 and the second area 1103. Through the above design, the present disclosure can use the first isolation groove 111 to solve the insulation problem between the coil lead terminal 131 and the relay monomer 120. Among them, when the area of ​​the cavity of the first shell 150 not occupied by the first base plate 110 and the relay monomer 120 and other structures is filled with the insulating filling material 160, at least the first isolation groove 111 can be filled with the insulating filling material 160, thereby forming a solid insulating material isolation between the first isolation groove 111 of the relay unit 100 and the transformer 140, thereby blocking the creepage path between the coil lead terminal 131 and the coil connection terminal 121 of the relay monomer 120 on the first base plate 110 to achieve isolation. In addition, the first isolation groove C1 can serve as an injection port and / or exhaust port for the insulating filling material 160 to ensure the density of the filling of the insulating filling material 160 and avoid the generation of blind cavities and pores inside after potting to affect the insulation effect. Of course, additional injection ports can also be set for the injection of the insulating filling material 160.

[0080] like Figure 7 As shown, based on the design that the isolation structure includes the first isolation groove 111, in one embodiment of the present disclosure, the first base plate 110 has a first edge 1104 and a second edge 1105 arranged at intervals along the second direction Y. Among them, the first isolation groove 111 can be opened at the first edge 1104. In some embodiments, the first isolation groove 111 can also be opened at the second edge 1105. Alternatively, when the first base plate 110 is provided with at least two first isolation grooves 111, at least two of the first isolation grooves 111 can be opened at the first edge 1104 at the same time, at least two of the first isolation grooves 111 can be opened at the second edge 1105 at the same time, at least one first isolation groove 111 can be opened at one of the first edge 1104 and the second edge 1105, and at least two first isolation grooves 111 are opened at the other of the first edge 1104 and the second edge 1105, all of which are not limited to the above embodiments.

[0081] like Figures 5 to 7 As shown, based on the design that the coil lead terminal 131 is closer to the first edge 1104 than the load lead terminal 132, in one embodiment of the present disclosure, the first isolation slot 111 may open at the first edge 1104. In some embodiments, when the coil lead terminal 131 is closer to the second edge 1105 than the load lead terminal 132, the first isolation slot 111 may also open at the second edge 1105. In addition, when the first bottom plate 110 is provided with at least two first isolation slots 111, the above-mentioned arrangement of opening at the first edge 1104 and / or the second edge 1105 may only be for at least one first isolation slot 111, and is not limited to the above-mentioned embodiment.

[0082] like Figures 5 to 7 As shown, based on the design that the isolation structure includes the first isolation groove 111, in one embodiment of the present disclosure, the first bottom plate 110 may be provided with at least two first isolation grooves 111, such as but not limited to the two first isolation grooves 111 shown in the figure. Among them, the depths of the at least two first isolation grooves 111 in the second direction Y are different, and among the at least two first isolation grooves 111, the one with the largest depth in the second direction Y opens at the first edge 1104. For example, in the embodiment shown in the figure, a design is adopted in which the first bottom plate 110 is provided with two first isolation grooves 111, and the two first isolation grooves 111 are respectively opened at the first edge 1104 and the second edge 1105 of the first bottom plate 110, and the depth of the first isolation groove 111 opened at the first edge 1104 in the second direction Y is greater than the depth of the other first isolation groove 111. When the first isolation grooves 111 are provided at both the first edge 1104 and the second edge 1105, the sum of the groove depths of the two first isolation grooves 111 along the second direction Y may be greater than the dimension of the first bottom plate 110 along the second direction Y, and the two first isolation grooves 111 are staggered in the first direction X. Through the above design, the present disclosure can further extend the creepage distance between the coil lead terminal 131 and the load lead terminal 132, and further improve the isolation effect between the high and low voltage sides.

[0083] like Figure 5 and Figure 6As shown, in one embodiment of the present disclosure, the coil connection terminal 121 of the relay monomer 120 and the coil lead-out terminal 131 of the relay module 100 can be connected to the transformer 140 via the wiring of the first base plate 110, and the transformer 140 is located on the side of the first base plate 110 where the relay monomer 120 is provided, and when the first base plate 110 is provided with an isolation structure, on a reference plane parallel to the first base plate 110, the orthographic projection figure of the transformer 140 can be at least partially located within the range of the orthographic projection figure of the isolation structure (e.g., the first isolation groove 111). Through the above design, the present disclosure can facilitate the arrangement of the transformer 140 and reduce the space occupied by the arrangement of the transformer 140. In addition, when the coil lead-out terminal 131 is closer to the first edge 1104 along the second direction Y than the load lead-out terminal 132, the connection position between the coil connection terminal 121 of the relay monomer 120 and the first base plate 110 can be arranged on the side closer to the first edge 1104 relative to the load connection terminal 122, thereby making it possible to make the wiring connecting the coil connection terminal 121 of the relay monomer 120 and the coil lead-out terminal 131 shorter and convenient to connect with the coil, further simplifying the wiring structure and reducing the difficulty of assembly. At the same time, the distance between the coil lead-out terminal 131 and the contact end of the relay monomer 120 is farther, which is beneficial to the isolation or insulation of the high and low voltage sides. Furthermore, when the relay module 100 does not include the relay monomer 120 and includes the first base plate 110, the present disclosure can also make full use of the space above the first base plate 110 by using the above design, so that the arrangement of each component on the first base plate 110 is more compact.

[0084] like Figures 5 to 7As shown, based on the design that the first base plate 110 has the first area 1102 and the second area 1103, in one embodiment of the present disclosure, the coil connection terminal 121 and the load connection terminal 122 of the relay monomer 120 are arranged at intervals along the second direction Y. On this basis, the isolation structure can also include a second isolation groove 112 that penetrates the first base plate 110 along the thickness direction, and the second isolation groove 112 is located between the coil connection terminal 121 and the load connection terminal 122 of the relay monomer 120. Through the above design, the present disclosure can use the second isolation groove 112 to extend the creepage path between the input and output of the relay monomer 120 on the first base plate 110. Among them, when the area of ​​the cavity of the first shell 150 not occupied by the first base plate 110 and the relay monomer 120 is filled with the insulating filling material 160, at least the second isolation groove 112 can be filled with the insulating filling material 160, and a solid insulating material isolation is formed between the second isolation groove 112 and the relay monomer 120, thereby blocking the creepage path of the coil connection terminal 121 and the load connection terminal 122 of the relay monomer 120 on the first base plate 110, and realizing the isolation between the input and output of the relay monomer 120. In addition, the second isolation groove C2 can be used as an injection port and / or exhaust port of the insulating filling material 160 to ensure the compactness of the filling of the insulating filling material 160, avoid the formation of blind cavities and pores inside after potting and affect the insulation effect, and of course, additional injection ports can be set for the injection of the insulating filling material 160.

[0085] like Figures 4 to 6As shown, based on the design that the first base plate 110 is provided with a second isolation groove 112, in one embodiment of the present disclosure, the relay module 100 proposed in the present disclosure may include at least two relay monomers 120 arranged along the first direction X, such as but not limited to the three relay monomers 120 shown in the accompanying drawings. The load connection terminals 122 of at least two relay monomers 120 are connected in series and connected between the two load lead terminals 132 of the relay module 100, thereby increasing the contact gap, thereby improving the dielectric withstand voltage between the contacts and the arc breaking ability when the contacts are disconnected. Among them, taking the first base plate 110 as an example of a roughly rectangular shape, the first direction X can be understood as the length direction of the rectangle. On this basis, the first base plate 110 can be provided with a second isolation groove 112, and the second isolation groove 112 is located between the coil connection terminal 121 and the load connection terminal 122 of each relay monomer 120, that is, the coil connection terminal 121 and the load connection terminal 122 of each relay monomer 120 are isolated at the same time through a second isolation groove 112. Through the above design, the present disclosure can simplify the structural complexity of the first base plate 110, reduce the processing difficulty of the first base plate 110, and at the same time help reduce the amount of raw materials used in the first base plate 110, which helps reduce material costs. In some embodiments, when there are at least two relay monomers 120, the first base plate 110 can also be provided with the same number of second isolation grooves 112 as the number of relay monomers 120, and the second isolation grooves 112 are arranged one-to-one with the relay monomers 120, which is not limited to this embodiment.

[0086] like Figures 4 to 7 As shown, in one embodiment of the present disclosure, the first base plate 110 may be provided with a third isolation groove 113 that penetrates along the thickness direction, the third isolation groove 113 opens at the edge of the first base plate 110, and the third isolation groove 113 is located between the two load lead terminals of the load connection terminal 122 of the relay monomer 120. Taking the three relay monomers 120 shown in the accompanying drawings as an example, the first base plate 110 is provided with three third isolation grooves 113, and the number of the third isolation grooves 113 is the same as the number of the relay monomers 120 and is arranged one-to-one. Through the above design, the present disclosure can use the third isolation groove 113 to improve the insulation between the two load connection terminals 122 of the relay monomer 120 on the first base plate 110. Among them, when the area of ​​the cavity of the first shell 150 not occupied by structures such as the first base plate 110 and the relay monomer 120 is filled with the insulating filling material 160, at least the third isolation groove 113 can be filled with the insulating filling material 160, and a solid insulating material isolation is formed between the third isolation groove 113 and the relay monomer 120, thereby blocking the creepage path and leakage channel of the two load connection terminals 122 of the relay monomer 120 on the first base plate 110, thereby achieving an isolation effect.

[0087] like Figure 6 and Figure 7 As shown, in one embodiment of the present disclosure, the first bottom plate 110 has a first edge 1104 and a second edge 1105 arranged at intervals along the second direction Y, and the coil lead terminal 131 is closer to the first edge 1104 than the load lead terminal 132 along the second direction Y. On this basis, the coil connection terminal 121 and the load connection terminal 122 of the relay unit 120 can be arranged at intervals along the second direction Y, and the coil connection terminal 121 is closer to the first edge 1104 than the load connection terminal 122.

[0088] like Figures 1 to 4 As shown, in one embodiment of the present disclosure, the relay module 100 proposed in the present disclosure also includes a first shell 150, which is connected to the first base plate 110. The first shell 150 and the first base plate 110 together form a accommodating space, which is suitable for accommodating the relay monomer 120 and filling the area not occupied by the relay monomer 120 with a potting material (for example but not limited to a potting glue, etc.).

[0089] like Figure 2 and Figure 3 As shown, based on the design that the relay module 100 includes a first shell 150, in one embodiment of the present disclosure, the first base plate 110 is located in the cavity of the first shell 150, and the area of ​​the cavity of the first shell 150 that is not occupied by structures such as the first base plate 110 and the relay monomer 120 is filled with an insulating filling material 160, thereby enabling the first base plate 110 and the relay monomer 120 and other structures to be encapsulated and fixed in the first shell.

[0090] like Figure 2 As shown, in one embodiment of the present disclosure, the bottom surface of the insulating filling material 160 is exposed from the opening of the first housing 150 , and the bottom surface of the insulating filling material 160 is the bottom surface of the relay module 100 .

[0091] like Figure 2 As shown, in one embodiment of the present disclosure, along the first direction X, each relay cell 120 may be located between two load lead terminals 132 of the relay module 100 .

[0092] like Fig. 9 and Fig.10As shown, in one embodiment of the present disclosure, the relay monomer 120 may specifically include a second housing 123, a base 124, an action component 125, an iron core 126, a static spring, and a coil component 127. The iron core 126 is disposed in the base 124 and partially extends out of the base 124 to form a pole surface, the action component 125 is movably disposed in the base 124, and the armature of the action component 125 is arranged corresponding to the pole surface of the iron core 126. The coil component 127 is disposed in the iron core 126, and the coil component 127 may include a winding (such as an enameled wire) and a coil frame. On this basis, the coil assembly 127 and the coil connection terminal 121 are assembled into a whole through the injection molding 128, the coil connection terminal 121 of the relay monomer 120 is led out from one side of the above whole, the coil assembly 127 and at least part of the coil connection terminal 121 are wrapped by the injection molding 129, and the load connection terminal 122 (such as a static spring) is led out from the other side of the above whole. Accordingly, the high-voltage side and the low-voltage side of the relay monomer 120 can achieve an insulation function suitable for a high-voltage application environment through the injection molding 128. In addition, the contacts on the load connection terminal 122 (such as the static contacts on the static spring) are connected in series through the action component. When the contacts of the relay monomer 120 are disconnected, the contact gap between the two load connection terminals 122 can be multiplied based on the design of the above-mentioned contact series connection, thereby improving the insulation performance of the relay monomer 120 itself, and further improving the safety and insulation reliability of the electrical appliance. Accordingly, the present disclosure increases the insulation capability between the control unit drive end and the automatic switch input end of the relay module 100 while also improving the insulation performance of the relay monomer 120 itself. Combined with this design of improving insulation performance both internally and externally, the present disclosure is more suitable for larger voltage scenarios and also places higher requirements on the dielectric withstand voltage performance of the relay module. Therefore, the present disclosure can meet the higher requirements of the above-mentioned type of relay monomer 120 for dielectric withstand voltage performance.

[0093] It should be noted that the relay modules shown in the drawings and described in this specification are only a few examples of the many types of relay modules 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 or any components of the relay modules shown in the drawings or described in this specification.

[0094] Based on the above detailed description of several exemplary embodiments of the relay module 100 proposed in the present disclosure, exemplary embodiments of the switch device proposed in the present disclosure will be described below.

[0095] See also Fig.11, which is a representative schematic diagram of the three-dimensional structure of the switch device proposed in the present disclosure. In this exemplary embodiment, the switch device proposed in the present disclosure is described by taking a programmable switch (also known as a matrix switch) 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 switch devices, 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 switch device proposed in the present disclosure.

[0096] Related References Figure 12 to Figure 14 , Fig.12 A three-dimensional structural schematic diagram of the switch device at another viewing angle is representatively shown in FIG. Fig.13 A schematic diagram of the system wiring plan of the switchgear is representatively shown in FIG. Fig.14 The structure, connection mode and functional relationship of each main component of the switch device proposed in the present disclosure will be described in detail below in conjunction with the above drawings.

[0097] like Figures 11 to 14 As shown, in one embodiment of the present disclosure, the switch device proposed in the present disclosure includes a second base plate 200 and a relay module 100 proposed in the present disclosure and described in detail in the above embodiment, the relay module 100 includes a relay monomer 110 and a first base plate 120 (it may also include only a relay monomer, that is, the relay module 100 may be a relay monomer), and the relay module 100 is arranged on the second base plate 200. Through the above design, since the coil lead-out terminal 131 and the load lead-out terminal 132 of the relay module 100 adopt an approximately diagonal arrangement, the present disclosure can achieve the best balance of the two external physical safety distances between the coil and the contact and between the disconnecting contacts, and can also achieve independent distribution of the high and low voltage sides in physical space. Accordingly, when designing the second base plate 200, the present disclosure can leave ample space between the coil and the contacts of the relay unit and between the disconnected contacts to arrange the isolation structure, which can not only realize the effective isolation of the coil drive side (low-voltage side) and the contact load terminal (high-voltage side) on the second base plate 200, avoiding the high-voltage side from interfering with the low-voltage side, but also ensure the effective isolation of the two lead-out terminals on the second base plate 200 when the contacts are disconnected, avoiding the load connection terminal 122 from generating a creepage path on the second base plate 200. Finally, the low-voltage side of the coil and the high-voltage side of the load (contact) can be clearly distinguished in the physical space on the second base plate 200, maximally avoiding the interference caused by the cross wiring of high and low voltages. In addition, the present disclosure is also conducive to realizing the straight wiring of the second base plate 200, avoiding the parasitic capacitance generated by the right-angle or sharp-angle wiring, and finally improving the test reliability under the high-voltage line.

[0098] like Fig.11As shown, in one embodiment of the present disclosure, the switch device proposed in the present disclosure may include eight relay modules 100. Among them, the eight relay modules 100 can be divided into two module units, and each module unit includes two module groups, and each module group includes at least two relay modules 100 (for example, but not limited to the two relay modules 100 shown in the figure). Specifically, through the wiring of the second base plate 200, the coil lead terminals 131 of each relay module 100 belonging to the same module group are connected, and the load lead terminals 132 of each relay module 100 belonging to the same module unit are respectively connected to the object under test. Accordingly, taking the switch device including eight relay modules 100 and each module group including two relay modules 100 as an example, the eight relay modules 100 shown in the figure can form a four-way output programmable switch, but its essence is a two-way output minimum programmable unit composed of four relays. Therefore, for various implementations that are positive integer multiples of the minimum programmable unit, they do not deviate from the design concept of the present disclosure. In some embodiments, based on the design that each module unit includes two module groups and each module group includes two relay modules 100, the number of module units included in the switch device proposed in the present disclosure may also be one, three, or more than three, and the number of relay modules 100 may be at least four, or may be a positive integer multiple of four. In some embodiments, each module group may also include only one relay module 100, and is not limited to the above embodiments.

[0099] like Fig.11 As shown, in one embodiment of the present disclosure, two module units are arranged along the second direction Y, two module groups belonging to the same module unit are arranged along the first direction X, and two relay modules 100 belonging to the same module group are arranged along the second direction Y. Wherein, the coil lead terminals 131 of the two relay modules 100 belonging to the same module group are located on the same side in the first direction X, and the load lead terminals 132 of the two relay modules 100 are located on the same other side.

[0100] like Fig.11 See also Figure 1 and Figure 8In one embodiment of the present disclosure, the relay module 100 includes a first housing 150, the first housing 150 is connected to the first base plate 110, and the first housing 150 and the first base plate 110 together form a storage space, which is suitable for accommodating the relay monomer 120 and filling the area not occupied by the relay monomer 120 with a potting material (such as but not limited to potting glue, etc.). On this basis, the opening of the first housing 150 can be provided with a positioning protrusion 151, and the relay module 100 is arranged on the second base plate 200 via the positioning protrusion 151. Through the above design, the present disclosure can use the positioning protrusion 151 to provide a support point for the first housing 150. Furthermore, the present disclosure can use the positioning protrusion 151 to form an air layer between the second base plate 200 and the first base plate 110 of the relay module 100, thereby achieving a heat dissipation effect. In addition, the present disclosure can use the positioning protrusion 151 to avoid direct contact between the bottom surface of the relay module 100 and the second base plate 200, thereby further extending the creepage distance.

[0101] like Figure 1 and Figure 8 As shown, based on the design that the first housing 150 is provided with a positioning protrusion 151, in one embodiment of the present disclosure, the positioning protrusion 151 can be located at the corner of the opening. Through the above design, the present disclosure can minimize the size of the second bottom plate 200 occupied by the positioning protrusion 151, ensure that the creepage distance between the positioning protrusion 151 and the coil lead terminal 131 and the load lead terminal 132 is completely avoided, and achieve effective avoidance between the positioning protrusion 151 and each avoidance groove of the second bottom plate 200, avoiding shortening of the creepage distance due to contact between the positioning protrusion 151 and the second bottom plate 200.

[0102] like Figures 11 to 14 As shown, in one embodiment of the present disclosure, the second base plate 200 may be provided with a fourth isolation groove 210 penetrating along the thickness direction, and the fourth isolation groove 210 is located between the high-voltage side and the low-voltage side of the relay module 100. The high-voltage side may be understood as the load lead terminal 132 side of the relay module 100 in the first direction X, and the low-voltage side may be understood as the coil lead terminal 131 side of the relay module 100 in the first direction X. Through the above design, the present disclosure utilizes the fourth isolation groove 210 to extend the creepage distance between the high-voltage side and the low-voltage side of the relay module 100 on the surface of the second base plate 200.

[0103] like Figures 11 to 14As shown, based on the design that the second base plate 200 is provided with a fourth isolation slot 210, in one embodiment of the present disclosure, when each module group includes at least two relay modules 100, the high-voltage side of each relay module 100 belonging to the same module group is located on the same side in the first direction X, and the two relay modules 100 can correspond to the same fourth isolation slot 210. In other words, only the fourth isolation slots 210 having the same number as the number of module groups need to be provided on the second base plate 200. Through the above design, the present disclosure can simplify the structural complexity of the second base plate 200 and reduce the difficulty of processing. In some embodiments, for each relay module 100 belonging to the same module group, the second base plate 200 can also be respectively provided with a corresponding number of fourth isolation slots 210, and these fourth isolation slots 210 are respectively arranged corresponding to each relay module 100 belonging to the same module group.

[0104] like Figures 11 to 14 As shown, in one embodiment of the present disclosure, when each module group of a plurality of module units is arranged along the second direction Y, the fourth isolation groove 210 can simultaneously correspond to each module group of each module unit located on the same side in the first direction X. Accordingly, only two fourth isolation grooves 210 need to be provided on the second bottom plate 200. Through the above design, the present disclosure can further simplify the structural complexity of the second bottom plate 200 and further reduce the difficulty of processing.

[0105] like Figures 11 to 14 As shown, in one embodiment of the present disclosure, the second base plate 200 is provided with a fifth isolation groove 220 penetrating along the thickness direction, and the fifth isolation groove 220 is located between the two load lead terminals 132 of the relay module 100. Through the above design, the present disclosure utilizes the fifth isolation groove 220 to extend the creepage distance between the two load lead terminals 132 on the surface of the second base plate 200.

[0106] like Figures 11 to 14 As shown, based on the design that the second base plate 200 is provided with the fifth isolation slot 220, in one embodiment of the present disclosure, when each module group includes at least two relay modules 100, the load lead terminals 132 of each relay module 100 belonging to the same module group can be located on the same side in the first direction X, and the two relay modules 100 can correspond to the same fifth isolation slot 220. In other words, only the fifth isolation slots 220 having the same number as the number of module groups need to be provided on the second base plate 200. Through the above design, the present disclosure can simplify the structural complexity of the second base plate 200 and reduce the difficulty of processing. In some embodiments, for each relay module 100 belonging to the same module group, the second base plate 200 can also be respectively provided with a corresponding number of fifth isolation slots 220, and these fifth isolation slots 220 are respectively arranged corresponding to each relay module 100 belonging to the same module group.

[0107] like Figures 11 to 14 As shown, in one embodiment of the present disclosure, when each module group of a plurality of module units is arranged along the second direction Y, the fifth isolation groove 220 can simultaneously correspond to each module group of each module unit located on the same side in the first direction X. Accordingly, only two fifth isolation grooves 220 need to be provided on the second bottom plate 200. Through the above design, the present disclosure can further simplify the structural complexity of the second bottom plate 200 and further reduce the difficulty of processing.

[0108] like Figures 11 to 14 As shown, in one embodiment of the present disclosure, a connecting channel 230 may be provided on the second base plate 200, and the connecting channel 230 is used to connect the load lead terminals 132 of two relay modules 100 belonging to different module groups. Accordingly, for one module unit, two connecting channels 230 arranged along the second direction Y are provided on the second base plate 200.

[0109] like Figures 11 to 14 As shown, based on the design of the connection channel being provided on the second base plate 200, in one embodiment of the present disclosure, a sixth isolation groove 240 may also be provided on the second base plate 200, and the sixth isolation groove 240 is located between two adjacent connection channels. Through the above design, the present disclosure can extend the creepage distance between two adjacent connection channels on the surface of the second base plate 200.

[0110] like Fig.13 , which is a representative schematic diagram of the system wiring plane of the switch device. Specifically, Fig.13 RLY1, RLY2, RLY3, RLY4, RLY5, RLY6, RLY7, and RLY8 represent eight relay modules 100, respectively; CH1, CH2, CH3, and CH4 represent four connection channels, respectively; the dotted line represents the connection path on the high-voltage side, and the dotted line represents the connection path on the low-voltage side. Accordingly, the switch device proposed in the present disclosure can at least realize the following programmable switch functions:

[0111] The switch circuit composed of relay contacts can be set by program to achieve flexible logical combination, so as to achieve the purpose of arbitrary selection and matching of channels, and finally realize programmable control during customer application. On this basis, the present disclosure can also realize a more concise wiring design, and due to the independent (no crossover) design of the high and low voltage sides in physical space, the present disclosure can further reduce the risk of high and low voltage crosstalk and improve insulation reliability (voltage resistance performance). For example: when RLY1 is combined with RLY6, channel CH1-CH2 is connected to complete the forward voltage test of one of the objects under test; when RLY1 is combined with RLY6, RLY7, and RLY8, channels CH1-CH2, CH1-CH3, and CH1-CH4 are connected at the same time, and the forward voltage test of multiple objects under test can be completed. When RLY2 is combined with RLY5, channel CH2-CH1 is connected to complete the reverse voltage test of one of the objects under test; when RLY2 is combined with RLY5, RLY7, and RLY8, channels CH2-CH1, CH2-CH3, and CH2-CH4 are connected at the same time, and the reverse voltage test of multiple objects under test can be completed. Specifically, taking the switch device including eight relay modules 100 shown in the accompanying drawings as an example, the programmable switch functions that can be realized can refer to the following table, where "×" represents logical interlocking, that is, simultaneous connection is not allowed, and "○" represents that a logical combination can be realized, for example, "CH1→CH2" represents that the current flows from channel CH1 to channel CH2.

[0112]

[0113] It should be noted that the switchgear shown in the drawings and described in this specification are only a few examples of the many types of switchgear that can employ 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 or any components of the switchgear shown in the drawings or described in this specification.

[0114] In summary, the relay module 100 proposed in the present disclosure includes a first base plate 110, and the first base plate 110 is provided with a coil lead terminal 131 and a load lead terminal 132, and the coil lead terminal 131 and the load lead terminal 132 are both led out by the relay module 100, and the coil lead terminal 131 and the load lead terminal 132 are respectively arranged adjacent to the two side edges of the first base plate 110 in the first direction X, and the coil lead terminal 131 and the load lead terminal 132 are respectively arranged adjacent to the two side edges of the first base plate 110 in the second direction Y. Through the above design, the relay module proposed in the present disclosure adopts a special arrangement form for the coil lead terminal 131 and the load lead terminal 132, which can achieve the best balance of the external physical safety distance between the coil and the contact and the independent distribution of the high and low voltage sides in physical space. The present disclosure optimizes the arrangement position of the coil lead terminal 131 and the load lead terminal 132 on the first base plate 110, thereby extending the distance between the coil lead terminal 131 and the load lead terminal 132, thereby extending the creepage distance between the high and low voltage sides of the relay module 100, and improving the insulation withstand voltage capability of the relay. In addition, the present disclosure can simplify the wiring of the circuit board (such as the first base plate 110 of the relay module 100 or the second base plate 200 of the switch device in the following embodiment), which is conducive to the modular design of the programmable switch device. Finally, the low-voltage side of the coil and the high-voltage side of the load (contact) can be clearly distinguished in the physical space on the circuit board, thereby maximizing the avoidance of interference caused by high and low voltage cross wiring.
