This utility model relates to the field of transformer technology, and more particularly to a transformer with multi-layer coating. It includes a main body and a recess formed on the main body, with a wear-resistant layer coated inside the recess. Two protective plates (first type) corresponding to the recess are provided on the main body. A moving component is provided on the main body to move the first protective plates. A second protective plate (second type) protecting the recess is placed between the two first protective plates. Uniformly distributed intercepting rods protecting the transformer are integrally connected between the two second protective plates. This utility model protects the transformer by coating the recess with a wear-resistant layer, thereby reducing external wear. The moving component on the main body prevents the wear-resistant layer from being applied, and the reinforcing mechanism locks the position of the first protective plates, enabling the first and second protective plates and the intercepting rods to provide impact protection for the main body, thus protecting the internal components.

This utility model discloses a connector for preventing wire detachment, specifically relating to the field of connector technology. It includes a connector base plate with a connecting groove on one side. A locking pin is fixedly connected to the inner cavity of the connecting groove. A conductive element is provided on one side of the connecting groove. A locking and positioning frame is provided on the side of the connector base plate near the conductive element. Fixing blocks are symmetrically fixedly connected to both sides of the connector base plate. This utility model firstly limits the insertion of plug pins by setting pin grooves, facilitating one-to-one correspondence and connection between the plug pins and one end of the conductive element. The anti-detachment block limits the connected plug, preventing detachment. Furthermore, the first locking hook at one end of the conductive element increases the strength of the connection between the plug pins and the conductive element, preventing detachment and ensuring tight contact between the plug pins and the wire connector pins. This reduces contact resistance, minimizes the effects of oxidation and wear, ensures a stable electrical connection, and improves the reliability of electrical signal transmission.
