[0002] In today's era of rapid development in communication technology and widespread use of electronic devices, efficient and stable signal transmission between communication and electronic equipment has become a key element. As an important component for realizing signal connection and transmission, the performance of the coupler directly affects the operating quality of the entire system.

[0003] Many traditional couplers use a threaded connection locking method. This method is cumbersome and time-consuming during actual installation and maintenance, greatly reducing work efficiency. Moreover, the threads are prone to wear and stripping during long-term use. Once the threads are damaged, it will not only lead to difficult disassembly and assembly, but may even prevent the coupler from connecting properly, seriously affecting the normal operation of the communication system.

[0004] Meanwhile, traditional couplers typically operate in complex environments and may be affected by external factors such as dust, moisture, and electromagnetic interference. However, many traditional couplers lack effective protective measures, leaving critical components such as the engagement and disengagement parts directly exposed to the external environment. In some industrial production environments, large amounts of dust can easily adhere to the coupler's engagement components, affecting their normal engagement and disengagement operations.

[0028] Reference Figure 1 , Figure 2 and Figure 3 As shown, an easily connectable coupler includes a connecting end 1, which comprises a bidirectional shell 11 and a connecting inner shell 12. The connecting inner shell 12 is symmetrically installed on the inner sides of both ends of the bidirectional shell 11 and is fixedly connected to the bidirectional shell 11. Both ends of the bidirectional shell 11 are fitted with mating connectors 2. Several engaging parts 3 that mate with the bidirectional shell 11 are provided on the outer surface of the connectors 2. A lever 4 that mates with the engaging parts 3 is also installed on the connectors 2. The lever 4 is rotatably connected to the connectors 2. A protective cover 5 protecting the engaging parts 3 and the lever 4 is also installed on the connectors 2. The design of the connecting end 1 using a bidirectional shell 11 and a connecting inner shell 12 enables bidirectional connection of the coupler, improving its flexibility. The connectors 2 are connected to the bidirectional shell 11 via engaging parts 3, making operation simple and convenient, and requiring no additional tools to complete the connection. The design of the lever 4 facilitates the operation of the locking component 3, making connection and disassembly easier. Compared with the traditional threaded connection locking method, it is not only faster to operate, but also effectively avoids the situation of difficult assembly and disassembly due to thread damage. The installation of the protective cover 5 can effectively protect the locking component 3 and the lever 4 from external dust, moisture and other corrosion, thus extending the service life of the coupler.

[0029] Reference Figure 2 and Figure 3 As shown, the bidirectional shell 11 includes a middle shell portion 111 and an outer tube portion 112 for mounting the two connectors. The outer tube portions 112 are symmetrically arranged at both ends of the middle shell portion 111 and are integrally formed with the middle shell portion 111. The integrally formed design of the middle shell portion 111 and the outer tube portion 112 of the bidirectional shell 11 ensures the structural strength and stability of the bidirectional shell 11. The outer tube portion 112 provides accurate positioning and stable support for the installation of the connectors 2, making the connection between the connectors 2 and the bidirectional shell 11 more tight and reliable. A guide transverse groove 113 is formed on the outer surface of the outer tube portion 112, and a longitudinal retaining groove 114 connected to one end of the guide transverse groove 113 is also formed on the outer surface of the outer tube portion 112. The guide transverse groove 113 and the longitudinal retaining groove 114 on the outer surface of the outer tube portion 112 provide guidance for the installation and positioning of the engaging component 3. When the connector 2 is connected to the bidirectional shell 11, the engaging member 3 can slide along the guide transverse groove 113 and then enter the longitudinal groove 114 to achieve engagement. This design makes the connection process smoother and improves the accuracy and stability of the connection.

[0030] Reference Figure 4 , Figure 5 and Figure 6As shown, the connector 2 includes an outer shell 21, an inner shell 22, and an optical fiber head 23 that mates with the inner shell 12. The outer shell 21 is fitted and fixed to the outside of the inner shell 22, and the optical fiber head 23 is fixedly installed at the center of the inner shell 22. The connector 2 uses the structure of the outer shell 21, inner shell 22, and optical fiber head 23. During installation, the outer shell 21 is fitted and fixed to the outer surface of the outer tube 112, enhancing the overall structural strength of the connector 2. The inner shell 22 is supported on the inner surface of the outer tube 112 for further support. The optical fiber head 23 is fixedly installed at the center of the inner shell 22, ensuring accurate fiber connection and stable transmission, thus improving the signal transmission performance of the coupler. The outer surface of the outer casing 21 is provided with a bent seat plate 211 for sliding installation of the locking component 3. The bent seat plate 211 is integrally formed with the outer casing 21. The bent seat plate 211 is provided with a side ear seat 212 for rotating installation of the lever component 4. The side ear seat 212 is fixedly connected to the bent seat plate 211. The bent seat plate 211 on the outer surface of the outer casing 21 provides a track for sliding installation of the locking component 3, ensuring the smooth sliding of the locking component 3. The side ear seat 212 provides support for the rotating installation of the lever component 4, allowing the lever component 4 to rotate flexibly. This facilitates the lifting operation of the locking component 3 when the lever component 4 is flipped, and thus facilitates quick release of the lock during disassembly.

[0031] Reference Figure 4 , Figure 5 and Figure 6 As shown, the engaging component 3 includes a column 31, a top cover 32, and a retaining spring 33. The column 31 is slidably mounted at the center of the bending base plate 211, with its lower end extending into the outer casing 21. The top cover 32 is fixedly mounted on the upper end face of the column 31, and the retaining spring 33 is fixedly mounted between the top cover 32 and the bending base plate 211. The structural design of the column 31, top cover 32, and retaining spring 33 in the engaging component 3 allows the retaining spring 33 to provide an upward elastic force to the column 31, ensuring a tight fit between the column 31 and the longitudinal slot 114 during engagement and guaranteeing connection stability. Simultaneously, when disassembly is required, the lever 4 can overcome the elastic force of the retaining spring 33, allowing the column 31 to disengage from the longitudinal slot 114 for easy disassembly.

[0032] Reference Figure 4 , Figure 5 and Figure 6As shown, the lever component 4 includes a clamping head 41 and a pressing bend 42. The clamping head 41 is clamped onto the column 31, and both sides of the clamping head 41 are rotatably connected to the side ear seat 212. The pressing bend 42 is fixedly installed at one end of the clamping head 41. The design of the clamping head 41 and pressing bend 42 in the lever component 4 allows the column 31 to move by rotating the pressing bend 42, making operation simple and convenient. This design allows operators to easily control the engagement and disengagement of the engaging component 3, improving the efficiency of coupler connection and disassembly.

[0033] In this embodiment, when connecting the coupler, the connector 2 is inserted into the outer tube 112 of the bidirectional housing 11, causing the post 31 of the engaging member 3 to slide along the guide groove 113. When the post 31 slides to the longitudinal groove 114, under the action of the holding spring 33, the post 31 enters the longitudinal groove 114 to achieve engagement, completing the connection. When disassembly is required, the pressing bend 42 of the lever member 4 is pressed, causing the clamping head 41 to rotate, thereby causing the post 31 to overcome the elastic force of the holding spring 33 and disengage from the longitudinal groove 114, allowing the connector 2 to be easily pulled out of the bidirectional housing 11.

[0034] The above are preferred embodiments of this utility model. Those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments described above. Any obvious improvements, substitutions or modifications made by those skilled in the art based on this utility model shall fall within the protection scope of this utility model.
