DETAILED DESCRIPTION
[0035] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.
[0036] In conjunction with the accompanying drawings, some implementation methods of the present application are described in detail below. In the absence of conflict, the following embodiments and features in the embodiments can be combined with each other.
[0037] Please refer to Figures 1 to 4 As shown, an embodiment of the utility model provides an FC male to LC female adapter, which includes: a first connector 101 and a second connector and a conversion core; the first end of the first connector 101 is plugged into the first end of the second connector; the conversion core includes a transfer post 170 located in the second connector; a first optical fiber core 171 and a second optical fiber core 172 are concentrically arranged and respectively connected to the two ends of the transfer post 170; the first optical fiber core 171 extends toward the second end of the second connector, and the second optical fiber core 172 extends into the first connector 101; the second connector has a first internal thread in its second end and a grid pattern 121 on its outer surface.
[0038] In this embodiment, an FC male to LC female adapter is proposed. The network pattern 121 provided on the second connector has stronger friction than a smooth surface or a vertically-striped surface. When screwing the connector to the device, the problem of not being able to be tightened due to insufficient surface friction is avoided. The grid pattern 121 provides more contact points and stronger gripping force, making it easier and more stable for the user to tighten the connector. Figure 1 and Figure 4 As shown, since the first optical fiber core 171 extends out of the second connector, and the second optical fiber core 172 is located in the first connector 101, wherein the first optical fiber core is an FC optical fiber, and the second optical fiber core is an LC optical fiber core, it becomes an FC male to LC female adapter. The concentrically arranged first optical fiber core 171 and second optical fiber core 172 reduce interference and loss during signal transmission, and improve transmission efficiency and quality.
[0039] The utility model provides an FC male to LC female adapter, wherein: Figure 4As shown, the second joint comprises an active joint 102, a first internal post 103 and a second internal post 104; the first internal post 103 is provided with a first blocking joint 131 at its middle, and a first end thereof is provided with an external thread 132; the second internal post 104 is provided with a second blocking joint 142 at its middle, and a second internal thread 143 thereof is provided with a second internal thread; the first internal post 103 and the second internal post 104 are respectively inserted from both ends of the active joint 102, and connected with the second internal thread through the external thread 132; the conversion core is located at the first internal post 10 3 and the second internal connection column 104, and the first optical fiber core 171 protrudes from the external joint of the second blocking node 142; the second optical fiber core 172 extends to the inside of the second end of the first blocking node 131; the first joint 101 is plugged into the second end of the first blocking node 131, and the second optical fiber core 172 extends to the inside of the first joint 101; the grid pattern 121 is arranged on the outside of the movable joint 102, and the first internal thread is arranged on the inside of the end of the movable joint 102 facing the second internal connection column 104.
[0040] The first internal connection column 103 and the second internal connection column 104 are connected, and the conversion core is arranged inside them, so as to enhance the structural stability of the entire adapter, and the connection between the external thread 132 and the second internal thread ensures the firmness of the internal structure, and reduces the structural deformation or damage caused by external pressure or vibration. The first connector 101 is plugged into the second end of the first plug 131, and the second optical fiber core 172 extends into the first connector 101, which simplifies the connection process and ensures the tightness and reliability of the connection; the grid pattern 121 is arranged on the outside of the movable joint 102, which not only increases the friction during operation, making the tightening process easier, but also further enhances the connection stability with the device through the arrangement of the first internal thread.
[0041] As a preferred implementation method, Figure 1 , Figure 3 and Figure 4 As shown, the first optical fiber core 171 is also sleeved with a first sleeve cap 105. Through the first sleeve cap 105, when it is not connected to the device, the first sleeve cap 105 covers the end of the first optical fiber core 171, so that the first optical fiber 171 can be kept clean to prevent excessive signal loss due to surface dirt; Figure 1 , Figure 2 and Figure 4 As shown, the second optical fiber core 172 is sleeved with a second sleeve cap 106 through the first connector 101 to ensure the cleanliness of the second optical fiber core 172 .
[0042] The utility model provides an FC male to LC female adapter. Figure 4As shown, it also includes a spring 108; the spring 108 is sleeved on one end of the adapter column 170 located at the first optical fiber core 171, and is located in the first internal column 103; the above-mentioned movable joint 102, the first internal column 103 and the second internal column 104 are all made of stainless steel; in addition, the above-mentioned adapter column 170 can also be preferably made of stainless steel.
[0043] By sleeved a spring 108 at one end of the adapter column 170 located at the first optical fiber core 171, the elasticity of the connection is increased. The spring 108 can provide a certain buffering effect during the connection, reduce the impact of external shock or vibration on the optical fiber core, thereby protecting the optical fiber core from damage and improving the stability and reliability of the connection; the movable joint 102, the first internal connection column 103 and the second internal connection column 104 are all made of stainless steel, which can significantly improve the corrosion resistance and durability of the adapter, making it suitable for use in a variety of environmental conditions and extending the service life of the adapter. Therefore, the introduction of the spring 108 and the use of stainless steel materials jointly optimize the internal structure of the adapter, which not only improves the mechanical strength of the adapter, but also enables the adapter to better adapt to various working environments and conditions, and improves its reliability in different application scenarios.
[0044] As a preferred implementation method, Figure 4 As shown, a protective tube 109 is also sleeved on the second optical fiber core 172; an opening is axially provided on the tube wall of the protective tube 109. The protective tube forms a protective layer on the second optical fiber core 172, i.e., the LC optical fiber core, and the opening is provided on the protective tube 109 to prevent the protective tube from being stuck because the diameter of the protective tube is small and thus it cannot be sleeved on the LC optical fiber core.
[0045] As a preferred embodiment, a fixing block 141 is further provided at one end of the second internal column 104 facing the outside of the movable joint 102. Through the fixing block 141, in cooperation with a slot set on the device, when the FC male to LC female adapter is connected to the device, the fixing block 141 is stuck in the slot to prevent the FC male to LC female adapter from being unstable, thereby ensuring the stability of the connection of the FC male to LC female adapter.

Therefore, the attached claims are intended to be interpreted as including optional embodiments and all changes and modifications that fall within the scope of the utility model embodiments.
[0047] Finally, it should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity from another entity, and do not necessarily require or imply any such actual relationship or order between these entities.
