[0022] See also Figure 1 , 2 A new type of rubber protective cap for a fuel injector connector includes: an elastic sealing area 3, a stretchable area 4, and a compressible airbag 1. The upper end of the stretchable area 4 is connected to the elastic sealing area 3, and the lower end of the compressible airbag 1 is connected to the elastic sealing area 3. It can effectively seal the injector pin to prevent the entry of harmful substances such as air and dust, keep the pin clean, effectively isolate the air, prevent the pin from getting damp and dirty, improve the stability and reliability of the injector, extend the service life of the injector, reduce the number of maintenance and cleaning times, and improve work efficiency.

[0023] The elastic sealing area 3 and the stretchable area 4 are both made of rubber material, which has strong corrosion resistance and can be used for a long time in harsh environments. For example, in adverse environments such as oil mist, they can effectively seal and protect the parts ports to prevent the entry of harmful substances such as dust and water vapor. They have a good dust-proof effect on the connector pin space, keep the connecting parts clean, are easy to fix, and not easy to fall off, ensuring that the sealing and protection effects are long-lasting and stable, thereby improving the reliability and stability of the equipment and extending the service life of the equipment.

[0024] The upper end of the elastic sealing area 3 is connected with a top cover 6, and the compressible airbag 1 passes through the top cover 6 and communicates with the elastic sealing area 3. During installation, the top cover 6 is pressed by hand to facilitate pressing the protective cap into and wrapping the opening of the connector.

[0025] The top cover 6 is a conical structure. The conical structure design of the top cover 6 makes it more convenient to install the protective cap. The protective cap can be pressed into and wrap the opening of the connector just by pressing the top cover 6 by hand.

[0026] A hook ring 2 is provided between the compressible air bag 1 and the top cover 6. The hook ring 2 can be hooked by fingers to pull the protective cap away from the injector connector.

[0027] The lower end of the stretchable area 4 is connected to the edge expansion protection area 5, and the lower end of the edge expansion protection area 5 is provided with an opening.

[0028] The extended protection zone 5 is a trapezoidal structure. The design of the trapezoidal structure of the extended protection zone 5 can spread the liquid when the protective cap is sprayed with liquid, thereby minimizing the risk of the product being splashed.

[0029] The branch-edge extension protection zone 5 is made of rubber material, which has strong corrosion resistance and can be used for a long time in harsh environments. For example, in adverse environments such as oil mist, it can effectively seal and protect the parts ports to prevent the entry of harmful substances such as dust and water vapor. It has a good dust-proof effect on the connector pin space, keeps the connecting parts clean, is easy to fix, and is not easy to fall off, ensuring that the sealing and protection effects are long-lasting and stable, thereby improving the reliability and stability of the equipment and extending the service life of the equipment.

[0030] When in use, you can pinch the compressible airbag 1 with your hands to discharge the gas in the extension protection area 5, the stretchable area 4, and the elastic sealing area 3. At this time, insert the extension protection area 5, the stretchable area 4, and the elastic sealing area 3 into the injector pin head. At this time, a relatively sealed space is formed inside the extension protection area 5, the stretchable area 4, and the elastic sealing area 3. After the hands are released, a relative space with negative pressure is formed in the sealing area. This makes the protective cover of the present application firmly pressed. The seal can keep the injector pin isolated from the air for a long time and prevent the pin from getting damp and dirty. The sealing effect is good, the structure is simple and practical, and it is safe and reliable.

[0031] The hook ring 2 is provided so that the protective cap can be pulled away from the injector connector by hooking the hook ring 2 with a finger.

[0032] The provision of the stretchable area 4 can cover the entire connector while wrapping the connector end, and its stretchability can meet the requirement of fully wrapping connectors of various lengths.

[0033] The top cover 6 can be used to press the top cover 6 by hand during installation to press the protective cap into and wrap the opening of the connector. It can also be used as the first level of umbrella protection.

[0034] The arrangement of the divided-edge extended protection zone 5 can spread the liquid when the protective cap is sprayed with liquid, thereby minimizing the risk of the product being sprayed.

[0035] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or alter the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or alterations made by a person of ordinary skill in the art without departing from the spirit and technical concept disclosed in the present invention shall still be covered by the claims of the present invention.
