[0019] The following will describe in detail some embodiments of the present application with reference to the accompanying drawings. Without conflict, the following various embodiments and the various features in the embodiments can be combined with each other.

[0020] Please refer to Figure 1 and Figure 2 As shown, an SC male-female attenuator provided by an embodiment of the present utility model includes a housing 8 and an upper housing 4, a lower housing 5 and an integrally provided SC male connector 1 and female connector 2 disposed inside the housing 8; a step 3 is provided between the SC male connector 1 and the SC female connector 2, and the step 3 is close to one side of the SC male connector 1; one end of the lower housing 5 is connected to the step 3 through a spring 6, and the female connector 2 penetrates through the other end inside the lower housing 5; one end of the upper housing 4 is connected to the lower housing 5 through the spring 6, and the SC male connector 1 penetrates out of the other end inside the upper housing 4; the housing 8 is disposed outside the upper housing 4 and the lower housing 5.

[0021] It should be noted that the above female connector 2 can be adapted to different types of connectors, such as LC, FC, and ST, etc.; an attenuating optical fiber doped with metal ions is usually adopted inside the SC male-female attenuator to achieve the signal attenuation effect. This optical fiber has an absorption effect on light, so it can effectively reduce the intensity of the optical signal. In addition, the male-female attenuator can also adopt PC (Physical Contact), UPC (Ultra Physical Contact), or APC (Angled Physical Contact) polishing techniques to adapt to different optical fiber connection requirements.

[0022] Furthermore, a bushing 7 is provided between the female connector 2 and the lower housing 5. Specifically, the bushing 7 is provided mainly for the following reasons: First, electrical insulation protection: The bushing 7 can provide electrical insulation to prevent current leakage or short - circuit. Especially when the distance between busbars is relatively close, the bushing 7 can effectively prevent arcing short - circuit due to phase - to - ground. Second, mechanical protection: The bushing 7 can protect the female connector from mechanical damage, reduce wear, and extend its service life. Third, environmental isolation: In some environments, such as humid or corrosive environments, the bushing 7 can act as a barrier to isolate the female connector 2 and reduce the impact of environmental factors on it. Fourth, facilitating identification and maintenance: The bushing 7 can help the staff more easily identify different circuits and provide convenience during maintenance and repair. Fifth, adapting to changes: In some application scenarios, the female connector 2 may need to adapt to building movement or vibration. The bushing 7 can provide a certain degree of flexibility and reduce stress concentration caused by these factors. Sixth, protection when passing through walls or other obstacles: When the busbar needs to pass through a wall or other obstacles, the bushing can provide additional protection to prevent direct contact and potential damage of the wall material to the busbar. Therefore, the bushing 7 is provided on the female connector 2 to ensure the safety and reliability of the electrical system and improve the overall performance and durability of the system.

[0023] As a preferred implementation, a connection assembly 51 is provided at one end of the lower housing 5 away from the step 3. Specifically, the connection assembly 51 is made of plastic and is symmetrically arranged on both sides of the lower housing 5. On the one hand, it is convenient for connection, assembly, disassembly, and on the other hand, it ensures the stability of its connection and fixation.

[0024] As a preferred implementation, the female connector 2 is provided with a shell cover 21. One end of the shell cover 21 is connected to the lower housing 5 through the connection assembly 51, and the female connector 2 is arranged inside the two. The other end of the shell cover 21 is embedded in the tail end of the outer shell 8 through the fixing component 211. Specifically, the shell cover 21 is fixedly and detachably connected to the upper housing 4 through the connection assembly 51. At the same time, one side of the shell cover 21 is fixedly installed on the tail end of the outer shell 8 through the fixing component 211. By setting the connection between the shell cover 21 and the lower housing 5, the protection of the female connector 2 is enhanced. When the female connector 2 needs to be connected and used, the shell cover 21 needs to be pulled out, and then the female connector 2 is connected to the target object.

[0025] As a preferred implementation, the outer shell mounting groove 81 is connected to the outside of the upper housing 4 and the lower housing 5 through a fixing block 41 provided on the upper housing 4. The SC male connector 1 extends out of the head end of the outer shell 8. Specifically, the outer shell mounting groove 81 is connected to the outside of the upper housing 4 and the lower housing 5 through a fixing block 41 provided on the upper housing 4, mainly to enhance the protection of the upper housing 4 and the lower housing 5.

[0026] As a preferred embodiment, a dust cap 11 is provided at the head end of the SC male connector 1; the dust cap 11 is transparent; specifically, the main functions of the dust cap 11 and the shell cover 21 are to protect the interface from external contaminants such as dust and debris, and can also prevent moisture intrusion to a certain extent, thereby protecting the internal electrical contact points, avoiding corrosion or oxidation. At the same time, the material has a certain elasticity and flexibility to closely fit the shape of the connector, and is made of wear-resistant and high-temperature resistant plastic materials to ensure sufficient strength and durability.

[0027] Furthermore, the main function of the transparent dust cap 11 in the adapter is to provide protection while allowing users to clearly see the shape of the connector interface.

[0028] As a preferred embodiment, the embodiment of the present utility model provides an SC male-female attenuator, which includes a housing 8 and an upper housing 4, a lower housing 5 arranged inside the housing 8, and an integrally arranged SC male connector 1 and female connector 2; a step 3 is provided between the SC male connector 1 and the female connector 2, and the step 3 is close to the side of the SC male connector 1; one end of the lower housing 5 is connected to the step 3 through a spring 6, and the female connector 2 is arranged through the other end inside the lower housing 5; one end of the upper housing 4 is connected to the lower housing 5 through the spring 6, and the SC male connector 1 passes through the other end inside the upper housing 4; the housing 8 is arranged outside the upper housing 4 and the lower housing 5; specifically, a compact and integrated solution is provided to achieve seamless connection between the SC male connector 1 and the female connector 2 in the optical fiber network; this design simplifies the installation process because it eliminates the need to install two different types of connectors separately, thereby saving space and reducing potential configuration errors; integrally arranged adapters usually have better mechanical strength and environmental adaptability because they are pre-designed and manufactured for specific application scenarios rather than field-assembled independent components; in addition, this design may also provide lower insertion loss and higher signal integrity, ensuring the quality and reliability of optical fiber communication.

[0029] Furthermore, when using the SC male-female attenuator, the dust cap 11 and the shell cover 21 need to be pulled out and then connected for use.

[0030] Furthermore, the SC male-female attenuator effectively reduces the optical signal energy transmitted by the optical fiber, avoiding distortion of the optical receiver due to excessive input optical power. This type of attenuator usually has a fixed or adjustable attenuation value, and the intensity of the optical signal can be adjusted according to needs to meet the power balance requirements in the communication system, etc.
