The invention comprises the following steps:
the invention aims to solve the problems in the prior art and provides a wiring structure of a magnetic bearing of a refrigeration compressor.
The invention adopts the technical scheme that: the utility model provides a refrigeration compressor magnetic bearing line structure, includes magnetic bearing and casing, the magnetic bearing is fixed in the casing, is equipped with two outlet holes on the casing symmetry, and the electric bearing line on the magnetic bearing is arranged in the outlet hole, still includes connecting piece, electric connector and terminal box, two the connecting piece pass through screw fixed connection on the casing, and two connecting pieces correspond two outlet holes seal, terminal box fixed connection on the casing, and two connecting pieces are arranged in the terminal box, and the electric bearing line on the magnetic bearing links to each other with the connecting piece, and the connecting piece passes through the connecting wire and links to each other with the electric connector, and the electric connector is fixed in the terminal box;
the connecting piece comprises a fixed plate, and a current wire contact pin and a sensor wire contact pin are inserted on the fixed plate.
Further, a sealing ring is arranged between the fixing plate and the casing.
Further, a sealing groove is formed in the shell, and a sealing ring is arranged in the sealing groove.
The invention has the following beneficial effects: the invention combines the original 2 small electric connectors into one, reduces one sealing, and reduces one sealing of the junction box cover without sealing. The connecting pieces at the left and right parts are covered by a junction box, and the junction box is provided with an electric connector which does not need to be sealed, so that the use effect is good.
Description of the drawings:
fig. 1 is a structural diagram of the present invention.
Fig. 2 is a top view of the connector of the present invention.
Fig. 3 is a front view of the connector of the present invention.
The specific embodiment is as follows:
the invention is further described below with reference to the accompanying drawings.
As shown in fig. 1 to 3, the invention discloses a magnetic bearing line structure of a refrigeration compressor, which comprises a magnetic bearing 1, a casing 2, connecting pieces 3, an electric connector 4 and a junction box 5, wherein the magnetic bearing 1 is fixed in the casing 2, two line outlet holes 11 are symmetrically arranged on the casing 2, an electric bearing line on the magnetic bearing 1 is arranged in the line outlet holes 11, the two connecting pieces 3 are fixedly connected on the casing 2 through screws, the two line outlet holes 11 are correspondingly sealed by the two connecting pieces 3, and the electric bearing line on the magnetic bearing 1 is connected with the connecting pieces 3.
