Abstract
Description
Technical Field
[0001] The present disclosure relates to a relay device. Background Art
[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 relay device design, the relay is installed on a circuit board (conductive lines are arranged on the bottom board). Since the distance between the two load connection terminals of the relay unit (for example, the load input side and the load output side) is relatively close, a leakage channel is formed between the two load sides on the bottom board, which means that higher leakage requirements cannot be met. In addition, since the surface of the bottom board needs to be arranged with conductive lines, and the wiring is generally irregular due to the limitations of the circuit structure, the wiring surface of the bottom board can only be designed as a plane. In addition, the presence of the pad and the residual flux around the pad after welding will further shorten the creepage distance of the relay along the surface of the circuit board, which means that higher insulation requirements cannot be met. Therefore, how to improve the insulation withstand voltage performance of the relay device has become an important issue that needs to be solved in this field. Utility Model Content

The structure, connection mode and functional relationship of each main component of the relay device proposed in the present disclosure will be described in detail below in conjunction with the above drawings.
[0063] like Figures 1 to 6 As shown, in one embodiment of the present disclosure, the relay device proposed in the present disclosure is a relay module 100, and the relay module 100 includes a first base plate 110 and a relay monomer 120, the relay monomer 120 is arranged on the first base plate 110, the first base plate 110 is the above-mentioned base plate, the relay monomer 120 is the above-mentioned relay unit, and the high-voltage side of the relay monomer 120 is provided with two load connection terminals 122 arranged at intervals, the two load connection terminals 122 are arranged at intervals along the first direction X, and the load connection terminals 122 are the above-mentioned load lead-out structure. The low-voltage side of the relay monomer 120 is provided with two coil connection terminals 121, the two coil connection terminals 121 are arranged at intervals along the first direction X, and the coil connection terminals 121 are the above-mentioned coil lead-out structure. In some embodiments, the high-voltage side of the relay monomer 120 may also be provided with three or more load connection terminals 122, and the low-voltage side may also be provided with three or more coil connection terminals 121. The first isolation groove C1 is disposed on the first base plate 110 and penetrates the first base plate 110 in the thickness direction, and the first isolation groove C1 is located between two adjacent load connection terminals 122 of the relay unit 120. Accordingly, the first isolation groove C1 can block the leakage path between the two load connection terminals 122 of the relay unit 120 on the surface of the first base plate 110, and can also extend the creepage path between the two load connection terminals 122 on the surface of the first base plate 110 to a certain extent, thereby improving the isolation performance and voltage resistance performance between the two load connection terminals 122 of the relay unit 120. Among them, when the first base plate 110 is disposed in the first housing 150 via the insulating filling material 160, at least the first isolation groove C1 can be filled with the insulating filling material 160, thereby forming a solid insulating material isolation between the two load connection terminals 122, further reducing the interference risk between the two load connection terminals 122.
[0064] like Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, the relay module 100 includes at least two relay monomers 120, for example but not limited to the three relay monomers 120 shown in the accompanying drawings. On this basis, the first base plate 110 can be provided with at least two first isolation grooves C1, that is, the number of the first isolation grooves C1 can be the same as the number of the relay monomers 120, and at least two first isolation grooves C1 are arranged one-to-one with at least two relay monomers 120. Through the above design, the present disclosure can improve the isolation performance between the two load connection terminals 122 of each relay monomer 120, and on this basis, sufficient space is reserved on the first base plate 110 for each load connection terminal 122 to connect. In some embodiments, when the relay device proposed in the present disclosure is a relay module 100, the relay module 100 may also include only one relay monomer 120, and when the high-voltage side of the relay monomer 120 is provided with two load connection terminals 122, the first base plate 110 may be provided with only one first isolation groove C1, and the first isolation groove C1 is located between the two load connection terminals 122 on the high-voltage side of the relay monomer 120, and is not limited to this embodiment.
[0065] like Figures 4 to 6 As shown, based on the design of one-to-one arrangement of the first isolation slot C1 and the relay monomer 120, in one embodiment of the present disclosure, at least two relay monomers 120 are arranged along the first direction X, the first direction X is parallel to the first base plate 110, and 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, the second direction Y is parallel to the first base plate 110 and perpendicular to the first direction X. On this basis, the load connection terminals 122 of at least two relay monomers 120 are located on the same side in the second direction Y, and one of the two side edges of the first base plate 110 in the second direction Y that is relatively close to the load connection terminal 122 is the first edge 1104, the coil lead terminal 131 is connected to the coil connection terminal 121 of the relay monomer 120 via the conductive circuit provided on the first base plate 110, and the load lead terminal 132 is connected to the load connection terminal 122 of the relay monomer 120 via the conductive circuit provided on the first base plate 110. Among them, the first isolation slot C1 opens at the first edge 1104.
[0066] See also Fig. 9 and Fig.10 , Fig. 9 A three-dimensional structural diagram of a partial structure of a relay module in another exemplary embodiment in accordance with the design concept of the present disclosure is representatively shown; Fig.10 Representatively shown in Fig. 9 FIG. 1 is a schematic diagram of the three-dimensional structure of the first base plate 110 .
[0067] like Fig. 9 and Fig.10 As 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 first base plate 110 is connected with a coil lead terminal 131 and a load lead terminal 132, 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. The first base plate 110 can be provided with a second isolation groove C2 penetrating along the thickness direction, and the second isolation groove C2 is located between the first area 1102 and the second area 1103. Through the above design, the present disclosure can use the second isolation groove C2 to extend the creepage path between the input (i.e. corresponding to the coil lead terminal 131) and the output (i.e. corresponding to the load lead terminal 132) of the relay module 100 on the surface of the first base plate 110. When the first base plate 110 is disposed in the first shell 150 via the insulating filling material 160, at least the second isolation groove C2 can be filled with the insulating filling material 160, thereby forming isolation of the solid insulating material. In addition, the second isolation groove C2 can serve as an injection port and / or exhaust port of the insulating filling material 160, thereby improving the compactness of the insulating filling material 160 filling and avoiding the generation of blind cavities and pores inside after potting to affect the insulation effect.
[0068] like Fig. 9 and Fig.10 As shown, based on the design that the first base plate 110 is provided with the second isolation groove C2, in one embodiment of the present disclosure, the first base plate 110 may be provided with at least two second isolation grooves C2, such as but not limited to the two second isolation grooves C2 shown in the drawings.
[0069] like Fig. 9 and Fig.10As shown, based on the design that the first bottom plate 110 is provided with the second isolation groove C2, in one embodiment of the present disclosure, the coil connection terminal 121 and the coil lead-out terminal 131 of the relay monomer 120 can be connected to the transformer 140 via the wiring of the first bottom plate 110, and the transformer 140 is located on the side of the first bottom plate 110 where the relay monomer 120 is provided, and on a reference plane parallel to the surface of the first bottom plate 110. 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. Accordingly, the wiring connecting the coil connection terminal 121 of the relay monomer 120 and the coil lead-out terminal 131 can be made shorter and easier to connect to 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.
[0070] like Fig. 9 and Fig.10 As shown, in one embodiment of the present disclosure, the first base plate 110 may be provided with a third isolation groove C3 penetrating along the thickness direction, and the third isolation groove C3 is located between the load connection terminal 122 (i.e., the high voltage side) and the coil connection terminal 121 (i.e., the low voltage side) of the relay monomer 120. Through the above design, the present disclosure can use the third isolation groove C3 to extend the creepage path between the load connection terminal 122 and the coil connection terminal 121 of the relay monomer 120 on the surface of the first base plate 110.
[0071] like Fig. 9 and Fig.10 As shown, in one embodiment of the present disclosure, still taking the relay module 100 including at least two relay monomers 120 as an example, the first base plate 110 can be provided with only one third isolation groove C3, and the third isolation groove C3 is arranged corresponding to at least two relay monomers 120 at the same time, 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 third isolation groove C3. 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.
[0072] Different from Fig. 9 and Fig.10In the illustrated embodiment, in an embodiment not shown in the present disclosure, taking the relay module 100 including at least two relay monomers 120 arranged along the first direction X as an example, the first base plate 100 may also be provided with at least two third isolation grooves C3, and the at least two third isolation grooves C3 are arranged one-to-one with the at least two relay monomers 120 respectively.

Through the above design, the present disclosure can use the insulating filling material 160 to form a solid insulation isolation between the coil connection terminal 121 and the load connection terminal 122 of the relay monomer 120, provide an isolation effect, and further improve the insulation withstand voltage performance of the relay device. In addition, each isolation groove opened on the first base plate 110 can be used as an injection port and / or exhaust port of the insulating filling material 160, and of course, an additional injection port can also be provided for the injection of the insulating filling material 160.
[0074] like Figure 2 and Figure 3 As shown, based on the design that the relay device includes a first shell 150 and an insulating filling material 160 is arranged inside the first shell 150, in one embodiment of the present disclosure, the insulating filling material 160 can also be filled in the area of the cavity of the first shell 150 that is not occupied by the first base plate 110 and the relay unit 120.
[0075] like Figures 3 to 5 As shown, in one embodiment of the present disclosure, when the relay device provided by the present disclosure is a relay module 100, the two load lead terminals 132 of the relay module 100 can be respectively located on the two outer sides of the load connection terminal 122 of the relay unit 120. Through the above design, the present disclosure can increase the distance between the two load lead terminals 132 of the relay module 100, increase the creepage distance or electrical clearance, and thus improve the insulation withstand voltage performance.
[0076] Based on the design that the two load lead terminals 132 are respectively located on the two outer sides of the load connection terminal 122 of the relay monomer 120, in one embodiment of the present disclosure, the relay device proposed in the present disclosure may include at least two relay monomers 120, such as but not limited to the three shown in the accompanying drawings, and the loads (contacts) of these relay monomers 120 are connected in series to increase the contact disconnection gap, thereby improving the dielectric withstand voltage between the contacts and the arc breaking ability when the contacts are disconnected. The coil connection terminals 121 of at least two relay monomers 120 are connected in parallel. On this basis, the two load lead terminals 132 of the relay module 100 can be respectively located at the two outermost sides of the at least two relay monomers 120. In other words, at least two relay monomers 120 are arranged between the two load lead terminals 132 of the relay module 100, that is, at least two relay monomers 120 are connected in series between the two load lead terminals 132.
[0077] like Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, when the relay device proposed in the present disclosure is a relay module 100, along a second direction Y parallel to the first base plate 110 and perpendicular to the first direction X, the coil connection terminal 121 of the relay cell 120 can be closer to the coil lead-out terminal 131 of the relay module 100 than the load connection terminal 122 of the relay cell 120, and the load connection terminal 122 of the relay cell 120 can be closer to the load lead-out terminal 132 of the relay module 100 than the coil connection terminal 121 of the relay cell 120.

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.
