[0026] Embodiment 1

[0027] In combination with the drawings Figures 1-5The utility model provides a contactor line board mounting structure, including contactor 1, contactor 1 one side is equipped with the outward protruding mounting box 2, contactor 1 is composed of contactor upper cover 11 and contactor base 12, and the mounting box 2 is directly set in the side by the outward protrusion of contactor 1, and contactor 1 and mounting box 2 are hollow shell structure, and the mounting box upper cover 21 and mounting box base 22 are respectively outward protrudingly arranged on contactor upper cover 11 and contactor base 12, and contactor upper cover 11 and mounting box upper cover 21 are integrated structure, and contactor base 12 and mounting box base 22 are integrated structure, therefore, the mounting box 2 and contactor 1 are integrated structure.

[0028] When contactor 1 separates contactor upper cover 11 and contactor base 12, the mounting box upper cover 21 and the mounting box base 22 of the mounting box 2 are separated synchronously, and when contactor upper cover 11 is installed on contactor base 12, the mounting box upper cover 21 is installed on the mounting box base 22 synchronously.

[0029] Contactor 1 is a conventional high-voltage direct-current contactor, and control line board 3 is installed in mounting box 2.

[0030] The integrated synchronous structure of contactor 1 and mounting box 2 can make the integrity of the contactor stronger, and also facilitate the setting of the line in the contactor 1 and the mounting box 2, and synchronous opening and closing are more convenient for connection and cooperation between lines.

[0031] The side of the mounting box 2 towards the contactor 1 is provided with a baffle 23, which is used to separate the internal space of the contactor 1 and the internal space of the mounting box 2, and prevent the internal lines from affecting each other.

[0032] The control line board 3 installed in the mounting box 2 is composed of a line board 31 and a plug-in seat 32, the plug-in seat 32 is installed at the side edge end of the line board 31, and the plug-in opening of the plug-in seat 32 is flush with the side edge of the line board 31.

[0033] Both sides of the internal space of the mounting box base 22 of the mounting box 2 are provided with guide grooves 24, the guide grooves 24 are composed of two symmetrical long ribs in the mounting box base 22, the guide grooves 24 are symmetrically arranged on the two side edges in the mounting box base 22, the guide grooves 24 are used to install the control line board 3, the line board 31 of the control line board 3 is inserted into the guide grooves 24, and the line board 31 is kept in a vertical state by the limiting of the guide grooves 24 and placed in the mounting box 2.

[0034] The mounting box upper cover 21 is also provided with guide grooves 24, so that the guide grooves 24 in the mounting box upper cover 21 also play a limiting role after the mounting box upper cover 21 and the mounting box base 22 are buckled.
