Abstract
The invention belongs to the field of computers, and particularly relates to a dampproof connector of a computer power line. The dampproof connector comprises a handhold head and a plug, wherein the plug is fixedly connected with a front side wall of the handhold head, the handhold head comprises a cavity, a spiral wire, a heat conduction rod, multiple water absorption strips and multiple water storage blocks, the cavity is arranged in the handhold head, a rear side of the cavity communicates with the exterior, one end of the spiral wire is fixedly connected with a side wall of the cavity andis electrically connected with the plug, the other end of the spiral wire extends to the handhold head and is connected with an external power supply, the heat conduction rod is arranged in the spiralwire, the heat conduction rod and the spiral wire are coaxially arranged, one end of the heat conduction rod is fixedly connected with the side wall of the cavity, the water absorption strip are embedded onto a front side wall of the handhold head, the multiple water absorption strips are uniformly arranged around an axis of the spiral wire, and one end of each water storage block is fixedly connected with the water absorption strip. The dampproof connector has a relatively high dampproof effect, the situation that the connector is affected with damp to get rust can be reduced, and the service lifetime of the power line is prolonged.
Description
technical field [0001] The invention belongs to the field of computers, in particular to a moisture-proof connector for computer power lines. Background technique [0002] Since the operating voltage of the core components of the computer is very low, and the operating frequency of the computer is very high, the requirements for the power supply are relatively high. At present, the power supply of the computer is a switching circuit, which converts ordinary alternating current into direct current, and then controls the voltage through chopping, and outputs different voltages to computer components such as the motherboard, hard disk, and optical drive. [0003] The computer power supply is generally connected to the external mains power supply through the power cord. During the use of the computer, because there will be a gap between the power cord plug and the computer power supply, a large amount of water vapor in the air will cause Corrosion at the joints will not only af...
