Description

Technical Field

[0001] The utility model relates to the technical field of energy connection equipment, in particular to a water-electricity integrated cable quick-plug connector. Background Art

[0002] The water-electricity integrated cable is widely used in medium frequency induction heating power supplies, machine tools and other equipment. Its basic structure is a bundle of wires in an insulating hose, and water is passed through it. When the wires generate a lot of heat due to the high current, the water flow in the hose plays a cooling role to prevent the wires from burning due to excessive temperature rise. The cross-section diagram of the existing water-electricity integrated cable is shown below. Figure 1 As shown, it includes an outer hose 11 and an electric wire 12 arranged in the hose 11. Water can be passed through the gap between the hose 11 and the electric wire 12 to achieve cooling. The above-mentioned water-electricity integrated cable is usually very long, with a maximum length of about 100 meters. It needs to be quickly disassembled from the equipment. A common practice is to use a quick pipe joint to achieve the quick disassembly function. The specific configuration of the quick pipe joint used in the prior art is as follows Figure 2 As shown, it includes a male plug 42 and a female socket 31. The female socket 31 is electrically connected to the inside of the device through a conductive tube 16. The male plug 42 is connected to the water-electricity integrated cable. When the male plug 42 is inserted into the female socket 31, water flows through the male plug 42 and the flow channel in the middle of the female socket 31, and the current contacts and communicates with the outer wall of the male plug 42 through the inner wall of the female socket 31, and is transmitted to the wire 12 through the copper pagoda 15. However, since the water-electricity integrated cable needs to pass both water and electricity, and the function of the quick pipe joint itself is only to pass water, and it is not designed to have the function of passing electricity. If it is used for electricity, not only will the electrical connection be unstable due to factors such as vibration, but there will also be safety hazards. In severe cases, it may cause poor contact at the joint and then heat, sparks, and burning. Utility Model Content
