Answer

**Step-by-Step Solution:**

1. **Identify the Devices**: The diaphragm, cervical cap, and vaults are all contraceptive devices used by females.

2. **Categorize the Devices**: These devices are classified as barrier contraceptives. They physically block sperm from entering the uterus.

3. **Function of the Devices**: Each of these devices is designed to cover the cervix, which is the lower part of the uterus that opens into the vagina. By covering the cervix, they prevent sperm from reaching the egg.

4. **Material and Usage**: These devices can be made from various materials, and they are typically reusable, meaning they can be cleaned and used multiple times.

5. **Distinguish from Other Methods**: It is important to differentiate these barrier methods from other contraceptive methods, such as intrauterine devices (IUDs) or hormonal implants, which work differently.

6. **Conclusion**: Therefore, the diaphragm, cervical cap, and vaults are reusable barrier contraceptive devices that cover the cervix to prevent pregnancy.
