Description

Technical Field

[0001] The utility model belongs to the technical field of plug equipment, in particular to a low-height and low-power plug. Background Art

[0002] The connectors of general electronic products and the plugs of electrical appliances are called plugs. Household AC power plugs and sockets have a male connector that protrudes in the shape of a rod or copper plate, which is physically inserted into a female connector-type power socket with a slot or a hole. Size is an important technical requirement that determines whether plugs, sockets and converters can be used safely and whether they meet the general interchangeability requirements to avoid misinsertion. Unqualified size will affect user use or cause hidden dangers such as poor contact and misinsertion, which may damage the equipment at the least and cause fire and electric shock accidents at the worst.

[0003] The following problems still exist in the prior art: 1. Voltage resistance performance problem: The distance between the power terminal and the brake terminal of the existing plug product is only 0.4mm, and the length of the fence between the power terminals is only 0.35mm. The electrical distance is too small, making it impossible to pass the 1500V high-voltage resistance test. It can only be solved by putting a heat shrink tube on the terminal, which seriously affects the efficiency and convenience of wiring harness production.

[0004] 2. Terminal fixing structure problem: The power terminal and the rubber core are fixed in such a way that both sides of the terminal are bent inward by a certain size and then hooked with the tongue of the rubber core. The front end of the terminal hanging platform is sharp, which can easily damage the tongue of the rubber core when inserted. The position of the inverted hook is too small, and the plastic tongue may be damaged when pulled outward. The holding force is too small, and the terminal is out of the rubber core, resulting in poor contact.

[0005] 3. The height of the existing low-power plugs on the market is 12mm, which will interfere with the equipment when small space requirements are required, affecting the usage occasions.

[0006] 4. Female terminal problem: The existing forward and reverse female terminals are bent at 90 degrees. There is a risk of cracking or breaking during the process of crimping and inserting the rubber core, which may cause the motor to burn during use. Since the terminal is at 90 degrees to the material strip, it cannot be wound tightly during coil packaging and is easy to spread out. If it is wound too tightly, there is a risk of damaging the terminal. At the same time, the number of packages per reel is small. Utility Model Content

The electrical distance meets the 1500V high-voltage test requirement of the tail clip, and the heat shrink tube process is eliminated, which improves the efficiency and convenience of wire harness production, achieving the goal of improving performance while reducing costs.

[0010] In a preferred embodiment, a threaded hole is formed on the upper surface of the plug shell, and the inner wall of the threaded hole is threadedly connected to the plug shell.

[0018] In a preferred embodiment, a partition is provided between the power terminals, and the length of the partition is 1.27 mm.

[0020] In a preferred embodiment, the power terminal and the rubber core are fixed in such a way that the terminal is folded into a U shape.

Since the tail clamp nut wrapped wire 10 structure is flipped 90 degrees and is 180 degrees with the connecting belt, the winding package is tighter and not easy to fall apart, which provides better protection for the terminals and allows for more packaging quantity.
