Description

Technical Field

[0001] This utility model relates to the field of DC connector technology, and in particular to a waterproof DC connector. Background Technology

[0002] DC connectors, as key connection components for DC power transmission, are widely used in various scenarios such as outdoor electronic equipment, medical devices, and industrial control devices. Their connection stability, waterproof performance, and structural strength directly determine the normal operation and service life of the equipment. However, current DC connector products on the market still face multiple technical challenges in practical applications, such as poor waterproof sealing, insufficient connection tightness, and easy structural damage, making it difficult to meet the needs of use in complex environments.

[0003] On the one hand, the existing DC connectors have obvious defects in waterproof design and poor connection tightness. Most DC connectors rely solely on simple rubber sleeves for waterproof sealing, lacking specialized sealing structures and fastening designs. In humid, rainy, or dusty environments, moisture and impurities can easily seep into the interior through the connection gaps between the connector and the equipment, leading to faults such as short circuits and poor contact.

[0004] On the one hand, the existing DC connectors generally lack structural strength and have poor resistance to pressure and bending. Since most DC connectors are made of a single plastic material for the handle and connection parts and do not have a special reinforcing structure, the handle is prone to breakage and deformation when subjected to external pressure, bending or drop impact during daily use. The connector body may also break internal wires due to bending, thus losing the power transmission function. Utility Model Content
