Description

Technical Field

[0001] This utility model relates to the field of engine wiring harness accessories, specifically a novel protective shell for the tail of a connector. Background Technology

[0002] With the advancement of Industry 4.0 and the development of intelligent manufacturing, the application scenarios of connectors in new energy vehicles, traditional automobiles, and other industrial fields are constantly expanding, and their usage is also increasing significantly. These application scenarios place higher demands on the reliability and stability of connectors, especially tail protection, which has become one of the key aspects to ensure their performance. Connectors must be able to operate normally under harsh conditions such as extreme temperatures, strong vibrations, high humidity, and salt spray.

[0003] However, in practical applications, if the connector's tail section lacks effective protective measures, problems such as loosening, short circuits, and corrosion can easily occur. In severe cases, this can even lead to electric shock accidents, affecting not only the connector's performance but also potentially endangering personal safety. Good tail section protection can significantly reduce the impact of external factors on the connector's internal structure, lower the probability of malfunctions, extend the connector's lifespan, and reduce maintenance costs and downtime, thereby improving overall operational efficiency.

[0004] Currently, known methods for external protection of wire harness connectors mainly involve using rubber sleeves or tape to connect the connector to the corrugated tube, thereby protecting the middle section of the wire. However, this traditional external protection method has significant shortcomings:

[0005] Excessive gap between parts: Because rubber sleeves or tape wrapping cannot achieve a tight fit, the protective effect is limited, especially in complex working environments such as high temperature, high humidity, and salt spray, which can easily lead to material aging and failure.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a novel protective shell for the tail of a connector, which has the following beneficial effects:

[0019] Example 1: Main body one and main body two are connected by connecting ribs. The matching design of the clip nose and clip window ensures the accuracy and firmness when the two are connected. The reserved cable tie holes provide convenience for additional fixation and enhance the stability of the overall structure.

[0020] Example 2: Based on Example 1, multiple latches and windows are added, especially at the front and waist positions, further strengthening the connection. The connector limiting ribs and positioning grooves effectively prevent connector misalignment, improving installation accuracy. The introduction of bellows limiting rib one and bellows positioning groove one, as well as the cooperation between the tail shell anti-misalignment hole and the rib plate, greatly enhances the protection of the bellows and tail shell.
