Description

Technical Field

[0001] The utility model technology belongs to the field of electromagnetic induction heating, specifically the connection between an electromagnetic induction heating machine and an induction heating coil. Background Art

[0002] In electromagnetic induction heating, especially medium-frequency induction heating, the induction heating copper tube coil not only needs to be connected to the medium-frequency power supply but also needs to be cooled by water flowing through the copper tube. The current connection method is to connect water and electricity separately. That is, first lock the cable with bolts and nuts on the heating copper tube coil, and then put the cooling water pipe on the copper tube and lock it with a hose clamp. This is very time-consuming and has low work efficiency. Summary of the Invention

[0003] To solve the deficiencies of the background art, the utility model technology provides a water-and-electricity integrated quick connector. The design idea is as follows: fix the cooling water pipe on the water nozzle of the quick connector body in advance, lock the induction power cable with nuts on the quick connector body, and there are sealing rings, washers and spring collets arranged in the connector body. When the induction coil copper tube is inserted into the spring collet, passes through the sealing ring and the washer and enters the connector body, tighten the locking nut. The washer and the sealing ring are axially pressed by the spring collet, so that the induction coil copper tube is sealed with the connector body. Further tighten the locking nut. The conical hole of the locking nut acts on the conical head of the spring collet, and the spring collet radially contracts to lock the induction coil copper tube, ensuring that the copper tube is in close contact with the spring collet and is electrically connected to the connector body, and the induced current flows to the induction coil.

[0004] When replacing the induction coil, just loosen the locking nut, pull out the induction coil copper tube, and then insert the new induction coil copper tube and tighten the locking nut to complete. Compared with the existing technology for replacing the induction coil, it has the beneficial effects of being fast and efficient, and improving work efficiency.
