Abstract

A detachable electrode holder is provided. The electrode holder includes a holder body, a positive electrode assembly, and a negative electrode assembly, where the holder body is provided with a mounting position; the positive electrode assembly is detachably arranged on the holder body, and the positive electrode assembly is located outside a first cavity of the holder body, and includes a positive electrode holder, a positive electrode wiring terminal arranged on the positive electrode holder, and a positive electrode wire arranged on the positive electrode holder; the negative electrode assembly is detachably arranged on the holder body and is located in the first cavity of the holder body, the negative electrode assembly is independently arranged relative to the positive electrode assembly, and the negative electrode assembly includes a negative electrode holder, a negative electrode wiring terminal arranged on the negative electrode holder, and a negative electrode wire.

Claims (55)

1 . A detachable electrode holder, comprising:

a holder body with an open first cavity, wherein the holder body is provided with a mounting position;

a positive electrode assembly detachably arranged at the mounting position of the holder body, wherein the positive electrode assembly is located outside the first cavity of the holder body, the positive electrode assembly comprises a positive electrode holder, a positive electrode wiring terminal arranged on the positive electrode holder, and a positive electrode wire arranged on the positive electrode holder, the positive electrode wire comprises a first insulating section and a first exposed section, and an end of the first insulating section of the positive electrode wire is connected to the positive electrode wiring terminal; and

a negative electrode assembly detachably arranged at the mounting position of the holder body, wherein the negative electrode assembly is partially located in the first cavity of the holder body, the negative electrode assembly is independently arranged relative to the positive electrode assembly, the negative electrode assembly comprises a negative electrode holder, a negative electrode wiring terminal arranged on the negative electrode holder, and a negative electrode wire arranged on the negative electrode holder, and an end of the negative electrode wire is connected to the negative electrode wiring terminal; the negative electrode wire comprises a second insulating section and a second exposed section, wherein, in an electrified state, the first exposed section of the positive electrode wire and the second exposed section of the negative electrode wire form a uniform electric field.

2 . The detachable electrode holder according to claim 1 , wherein the mounting position comprises a first mounting groove fitting with the positive electrode holder and a second mounting groove fitting with the negative electrode holder, the positive electrode holder is arranged in the first mounting groove, and the negative electrode holder is arranged in the second mounting groove.

3 . The detachable electrode holder according to claim 2 , wherein a thickness of the positive electrode holder is less than or equal to a depth of the first mounting groove, and a thickness of the negative electrode holder is less than or equal to a depth of the second mounting groove.

4 . An electrophoresis device, comprising:
