[0042] Example

[0043] This embodiment provides a two-input and two-output 1500V DC isolating switch. Figure 1 and 2 As shown, it includes two contact modules 1 and an operating module 2 .

[0044] Two contact modules 1 are arranged side by side with the operating module 2, and multiple modules are assembled by fasteners. The contact module 1 includes a contact module body 10 and a contact assembly arranged in the contact module body 10. The contact assembly includes a moving contact 11 and a stationary contact 12. In this embodiment, the fasteners are pins or rivets.

[0045] The contact module body 10 has a moving contact frame 15 rotating around its center, and the moving contact frame 15 has two moving contacts 11 arranged on both sides of its rotation center. There are two corresponding static contacts 12 and arc extinguishing chambers 13, wherein the rotation angle of the moving contact frame 15 is 0-110°, so that the opening distance between the moving and static contacts is large, thereby improving the breaking capacity. In this embodiment, the cross-section of the contact module body 10 is square, which effectively utilizes the space.

[0046] Stationary contact 12, such as Figure 4 , 7As shown in Figures 1 and 8, it has a first connecting plate 121 and a second connecting plate 122 that are bent and connected and have opposite current directions, wherein the opening and disconnecting position of the moving contact 11 and the static contact 12 is between the first connecting plate 121 and the arc extinguishing chamber 13, and the second connecting plate 122 is located on the side of the first connecting plate 121 away from the arc extinguishing chamber 13. In this embodiment, the first connecting plate 121 and the second connecting plate 122 are bent into a U shape.

[0047] like Figure 7 As shown, the static contact 12 also has a first static contact plate 123 and a second static contact plate 124, the length of the second static contact plate 124 is longer than that of the first static contact plate 123, the first static contact plate 123 is vertically arranged on one side of the first connecting plate 121, the second static contact plate 124 is L-shaped, and the transverse plate portion 1241 of the L-shaped second static contact plate 124 is fixedly connected to the second connecting plate 122, a gap is provided between the vertical plate portion 1242 and the first static contact plate 123, and the plane where the vertical plate portion 1242 is located is vertically arranged to the plane where the first static contact plate 123 is located, the vertical plate portion 1242 extends to the inside of the arc extinguishing chamber 13, and the magnetizing plate 14 between the transverse plate portion 1241 and the second connecting plate 122 is conducive to blowing the arc to the arc extinguishing chamber 13.

[0048] The moving contact 11, such as Figure 4-6 As shown, it has two left-right symmetrically arranged first moving contact plates 113 and two left-right symmetrically arranged second moving contact plates 114, the two first moving contact plates 113 are arranged between the two second moving contact plates 114, and the length of the second moving contact plate 114 is longer than the length of the first moving contact plate 113. Figure 4 As shown, the moving contact frame 15 rotates clockwise, the second moving contact plate 114 first contacts and communicates with the second static contact plate 124, and the first moving contact plate 113 then contacts and communicates with the first static contact plate 123; when opening the switch, the second moving contact plate 114 first separates and disconnects from the second static contact plate 124, and the first moving contact plate 113 then separates and disconnects from the first static contact plate 123. In this embodiment, only the first moving contact plate 113 and the first static contact plate 123 are provided with contacts, and the above structure is set so that the arc is only generated between the second moving contact plate 114 and the second static contact plate 124. Since the first moving contact plate 113 and the first static contact plate 123 are set away from the arc, the first moving contact plate 113 and the first static contact plate 123 are used as the active contact and the main static contact respectively, and the contacts are not easily eroded by the arc, thereby extending the service life.

[0049] As a convertible embodiment, the static contact 12 has a first static contact plate 123 and a second static contact plate 124, wherein, when the circuit is closed, the second static contact plate 124 contacts and connects with the moving contact 11 before the first static contact plate 123; when the circuit is opened, the second static contact plate 124 separates and disconnects from the moving contact 11 after the first static contact plate 123.

[0050] As a convertible embodiment, the moving contact 11 has a first moving contact plate 113 and a second moving contact plate 114, wherein, when the circuit is closed, the second moving contact plate 114 contacts and connects with the static contact 12 before the first moving contact plate 113; when the circuit is opened, the second moving contact plate 114 separates and disconnects from the static contact 12 after the first moving contact plate 113.
