Description

Wire harness connector with terminal anti-drop structure Technical Field The utility model relates to the technical field of connector falling-off prevention, in particular to a wire harness connector with a terminal falling-off prevention structure. Background The wire harness connector is used as a key component for realizing circuit connection and signal transmission in an electrical system, and is widely applied to the fields of automobile manufacturing, aerospace, industrial automation, consumer electronics and the like. The system ensures stable transmission of power and data among devices through reliable electrical connection, and plays a decisive role in normal operation of the system. In practical applications, the harness connector generally comprises the following core components: 1. the connecting terminal is a core component of the wire harness connector and is responsible for electric connection with the lead, and the material of the connecting terminal is generally copper alloy with good conductivity and is subjected to surface treatment to enhance the oxidation resistance and corrosion resistance; 2. The housing serves to protect the internal terminals and insulation while providing mechanical support for the mounting and securing of the connector, and is typically made of a high strength, flame retardant engineering plastic; 3. The sealing component is used for preventing invasion of external pollutants such as water, dust, oil stains and the like, ensuring the electrical performance of the connector in a severe environment, and common sealing materials include rubber, silica gel and the like; 4. the locking mechanism is used for ensuring the stability of the connector in a connection state and preventing accidental falling, and common forms comprise a buckle, a locking plate and the like. At present, manufacturers adopt various structural designs and technical means for ensuring the reliable connection of the wire harness connectors. Part of manufacturers can ensure the connection tightness and the operation convenience in the plug process of the connector by optimizing the plug force design of the terminals, the manufacturers add an anti-misplug structure on the shell to avoid connection failure caused by misplug direction, and the manufacturers adopt a multi-layer sealing design on the sealing part to improve the waterproof and dustproof performance. However, the above embodiment still has the following problems, in terms of terminal connection stability, the existing connector lacks effective limit, when the equipment is in complicated working conditions such as high-frequency vibration, severe impact or long-term high temperature, the terminal may be loose due to vibration, external force pulling or thermal expansion and shrinkage, the situation that the contact is poor or even drops occurs, the existing locking mechanism is mainly fixed by means of a single anti-drop structure, the situation that the connector terminal is easy to loose or even drop after long-term use is only relied on by a common buckle, the terminal drops, not only can cause circuit interruption and signal loss, causes equipment shutdown and functional failure, but also can generate electric spark due to poor contact, brings about potential safety hazards such as fire and the like, a solution is provided, the problem that the double anti-drop structure of the terminal is arranged on the wire harness connector, the contact defect caused by drop is reduced, the connector is always in the correct position, the connection reliability is effectively improved, and various risks caused by the drop of the terminal is reduced.
