Description

Technical Field

[0001] The utility model relates to the field of low-voltage electrical equipment, and in particular to an isolating switch and a connection structure. Background Art

[0002] An isolating switch is a switching device mainly used to isolate power supplies and open and close current circuits. It has two major functions: switching and isolating. It is a safe, reliable, practical and economical low-voltage switching device.

[0003] Existing isolating switches usually need to be directly connected to the PCB board to improve space utilization and reduce production costs; however, for an isolating switch in which the rotation center axis of the moving contact assembly of the isolating switch is 90 degrees to the operating rotation axis of the operating mechanism, the gas generated during the opening and closing process can only be discharged on the same side as the static contact assembly. Therefore, the gas outlet of the isolating switch is on the same side as the PCB board, which can easily cause a short circuit on the PCB board when an arc is generated. Utility Model Content

[0038] Please refer to Figure 1 and Figure 2 In one aspect of the present embodiment, a disconnector 100 is provided, which includes an operating mechanism 110 and a contact mechanism 120 connected to each other. The contact mechanism 120 includes a plurality of contact modules 121 stacked in sequence. The contact module 121 includes a shell and a moving contact assembly arranged in the shell. The rotation center axis of the moving contact assembly is perpendicular to the rotation axis of the operating mechanism 110.

The plane a where the air outlet direction of the air outlet is located is parallel to the board surface of the PCB board 210.

[0039] Specifically, the present application provides an isolating switch 100, which includes an operating mechanism 110 and a contact mechanism 120, wherein the operating mechanism 110 is connected to the contact mechanism 120; the contact mechanism 120 is formed by a combination of a plurality of contact modules 121 stacked in sequence. The contact module 121 includes a housing and a moving contact assembly and a stationary contact assembly arranged in the housing; the operating mechanism 110 can drive the moving contact assembly to rotate around a central axis to contact or separate from the stationary contact assembly, thereby realizing the closing or opening of the isolating switch 100. Preferably, the isolating switch 100 also includes a handle 130, which is connected to a side of the operating mechanism 110 away from the contact mechanism 120, and the operating mechanism 110 can be driven to rotate by the handle 130, thereby driving the closing or opening of the contact mechanism 120.

[0040] The rotation center axis of the moving contact assembly is perpendicular to the rotation axis of the operating mechanism 110. One side of the contact structure is connected to the PCB board 210 of the connection structure 200 to improve space utilization. The contact mechanism 120 includes an air outlet 122. The gas generated by the multiple contact modules 121 when closing or opening the switch can be discharged to the outside through the air outlet 122. Fig.10 The plane a where the gas outlet direction of the gas outlet is located is parallel to the board surface of the PCB board 210 to ensure that when the gas outlet 122 discharges gas to the outside, it will not contact the PCB board 210, thereby avoiding the arc generated during the closing or opening process of the disconnector 100, resulting in a short circuit of the PCB board 210.

[0041] It should be noted that in the embodiment of the present application, first, the contact mechanism 120 includes a cover plate 123, which covers at least one side of the multiple contact modules 121 and is perpendicular to the plane where the contact modules 121 are located; at least one through groove 1231 is provided on a side of the cover plate 123 facing the contact mechanism 120, and the plane b where the through groove extends is parallel to the board surface of the PCB board 210; one end of the through groove 1231 is connected to the outside to form an air outlet 122.

[0042] Specifically, Figure 6 As shown, the contact mechanism 120 includes a cover plate 123, and the contact mechanism 120 is formed by a plurality of contact modules 121 stacked in sequence. The cover plate 123 is arranged on at least one side of the contact module 121, and the plate surface of the cover plate 123 is perpendicular to the plate surface where the contact module 121 is located; the cover plate 123 is provided with at least one through groove 1231 on one side facing the contact module 121, and one end of the through groove 1231 extends to the edge of the cover plate 123 and is connected to the outside to form an air outlet 122, and the gas generated by each contact module 121 when opening or closing the switch can be gathered in the through groove 1231 and discharged to the outside through the air outlet 122 at its end; wherein, please combine Figure 6 and Fig.11 The plane b where the through groove extends is parallel to the surface of the PCB board 210 to ensure that the gas outlet 122 will not contact the PCB board 210 when discharging gas to the outside, thereby avoiding arcing during the closing or opening process of the disconnector 100, which may cause a short circuit in the PCB board 210.

[0043] Second, the contact module 121 includes at least one sub-air outlet 1211 , the sub-air outlet 1211 corresponds to the position of the through slot 1231 , and the plane where the air outlet direction of the sub-air outlet 1211 is located is perpendicular to the plane where the through slot 1231 is located.

[0044] Specifically, Figure 1As shown, the contact module 121 includes at least one sub-gas outlet 1211. When the isolating switch 100 is connected to the PCB board 210, the plane where the gas outlet direction of the sub-gas outlet 1211 is located is perpendicular to the board surface of the PCB board 210. Therefore, the gas discharged from the sub-gas outlet 1211 is easy to contact the PCB board 210 and cause a short circuit. A cover plate 123 is provided at the end of the contact module 121. The position of the through groove 1231 of the cover plate 123 corresponds to the position of the sub-gas outlet 1211 of the contact module 121, and the sub-gas outlet The plane where the gas outlet direction of the outlet 1211 is located is perpendicular to the plane where the through groove 1231 is located. Therefore, the gas discharged from the sub-outlet 1211 of each contact module 121 can be gathered by the through groove 1231 and discharged through the outlet 122 at its end. This arrangement changes the exhaust direction of each contact module 121 to ensure that when the outlet 122 discharges gas to the outside, it will not contact the PCB board 210, thereby avoiding the generation of an arc during the closing or opening process of the isolating switch 100, resulting in a short circuit of the PCB board 210.

[0045] Preferably, the contact mechanism 120 includes at least two air outlets 122, at least one air outlet 122 is arranged on a side of the contact mechanism 120 close to the PCB board 210, and the remaining air outlets 122 are arranged on a side of the contact mechanism 120 away from the PCB board 210, so that the air outlets 122 are arranged on opposite sides of the contact mechanism 120 to increase the exhaust efficiency of the contact mechanism 120, thereby further improving the reliability and safety of the contact mechanism 120.

The plane a where the air outlet direction of the air outlet is located is parallel to the board surface of the PCB board 210. The disconnector 100 obtained by the above design can ensure that the plane a where the air outlet direction of the air outlet of the disconnector 100 is located is parallel to the board surface of the PCB board 210. When the disconnector 100 is opened or closed, it is not easy to cause a short circuit on the PCB board 210, thereby improving the use safety and reliability of the disconnector 100.
