[0035] The preferred mechanism and method of motion implementation of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0036] A hybrid optoelectronic conduit connector is disclosed, which mainly consists of three parts: a main structural component 100, a traction cap 200, and a plug-in structural component 300. The traction cap 200 and the plug-in structural component 300 are selectively mounted on the main structural component 100 according to different application scenarios.
[0037] like Figures 1 to 4 As shown, the inner housing 102 is generally cylindrical. The outer surface of the inner housing 102 has a snap-fit portion 101, which is a protruding snap-fit structure. The rear end of the snap-fit has an end face perpendicular to the main body of the inner housing 102, and the front end of the snap-fit is configured as a slope facing the front end. The inner housing 102 is configured with a groove that opens from the center outwards. The groove is used to accommodate optical fibers. Specifically, the inner housing 102 is configured with a V-shaped groove 103 that gradually expands from the center outwards. The V-shaped groove 103 is used to accommodate optical fibers. The tip of the V-shaped groove 103 is used to accommodate the optical fiber portion of the hybrid optical-electric cable. The front part of the inner housing 102 has a receiving cavity 104. The inner housing 102 allows optical fibers to enter from the rear end and exit from the front end to the ceramic ferrule assembly.
[0038] A ceramic ferrule assembly is located at the front end of the inner housing 102. The assembly includes a spring 105, a tail shank 106, and a ceramic ferrule 107. The ceramic ferrule 107 is fixed to the tail shank 106. The spring 105 is sleeved on the tail shank 106 and abuts against the retainer 108 of the tail shank 106. The other end of the spring 105 abuts against the front end face of the inner housing 102. A receiving cavity 104 is used to receive the tail shank 106. The interior of the ceramic ferrule 107 is used to pass through and accommodate optical fibers. The front end face of the optical fiber is located on the front end face of the ceramic ferrule 107, thereby enabling communication. The spring allows the ceramic ferrule 107 to move backward when compressed and rebound when the external force is removed, thus achieving tight contact between the front end face of the ceramic ferrule 107 and the adapter end, ensuring signal transmission. Meanwhile, when the ceramic ferrule 107 moves backward under force, the portion of the optical fiber located in the V-groove 103 (or U-groove) is protected by the V-groove 103. This design ensures the stability of the optical fiber's position when it is at the bottom of the V-groove 103, while also providing space for the optical fiber to bend when the ceramic ferrule moves backward. The optical fiber can bend to a certain extent within the V-groove 103, ensuring that the optical fiber will not break.
[0039] The inner housing 102 has first conductive element locking portions 109 on both sides, and two first conductive elements 110 are provided and fixed to the first conductive element locking portions 109. The first conductive element locking portions 109 are configured in a slot shape, allowing the first conductive element 110 to be inserted forward from the rear end of the first conductive element locking portion 109. At the same time, the first conductive element 110 is provided with a protruding protrusion 111, and the first conductive element locking portion 109 is provided with a bayonet 112. When the first conductive element 110 is inserted into the set position, the bayonet 112 cooperates with the protrusion 111 to catch the first conductive element 110, preventing it from being pulled out from the rear, thereby fixing the first conductive element 110 in the first conductive element locking portion 109. The rear end of the first conductive element 110 has a welding portion 113, which is used for electrical connection with the conductive wire 120 of the optical hybrid cable. The front part of the first conductive element 110 has a first conductive contact portion 114.
[0040] The tailstock 115 is fixed to the tail end of the inner housing 102. The tail end of the inner housing 102 has a protrusion 116, and the tailstock 115 has a bayonet 117 in the middle, allowing the tailstock 115 to be inserted into and fixed to the tail of the inner housing 102. The outer surface of the tailstock 115 has a threaded portion 118. The tailstock 115 can be inserted into the tail of the inner housing 102 and can cover the welded portion 113, thereby protecting the weld point. However, it must ensure that the first conductive contact portion 114 is exposed, or that other components can be inserted to allow the first conductive contact portion 114 to achieve electrical connection. A tail sleeve 119 can be installed at the tail of the tailstock 115 to prevent the optoelectronic hybrid cable from bending excessively.
[0041] Application scenario for tubing: Using a 200mm towing cap. (Example) Figure 4 As shown, the towing cap 200 has an internal thread for engaging with the threaded portion 118 of the tailstock 115, allowing the towing cap 200 to be detachably mounted on the main structural member 100. The front end of the towing cap 200 has a towing port 201, which can secure the towing rope, thus enabling pulling operations. The towing cap 200 is fixed to the main structural member 100, sealing the entire main body of the main structural member 100, at least covering the ceramic insert assembly and the first conductive contact portion 114, ensuring that the main structural member 100 is not damaged. In this patent, the locking part of the towing cap and the locking part of the main body are in a detachable form with a threaded engagement. Other detachable forms, such as a spring arm and a latch, or a latch block and a latch, are also acceptable, as long as they ensure stable traction and prevent detachment during towing.
[0042] like Figures 5 to 10As shown, the plug-in structure 300 has a first outer shell 301, which is configured to have a connecting portion. The first outer shell 301 is generally square and can be configured as the inner shell shape of an SC type connector, with an internal cavity 304 for accommodating the main structure 100. Specifically, the connecting portion is configured with an elastic arm 302 on one surface of the first outer shell 301. The front end of the elastic arm 302 can be configured to be slightly bent inward, so as to better abut against the snap-fit portion 101 of the inner shell 102. The front part of the front end face of the elastic arm 302 is provided with a receiving portion 303 in the first outer shell 301.
[0043] The second conductive element 306 is fixed to the first outer casing 301. Specifically, the first outer casing 301 is provided with a plate-shaped bayonet 307 and a receiving groove 308. A protrusion 309 is formed between the plate-shaped bayonet 307 and the receiving groove 308. The front end of the second conductive element 306 forms an arc-shaped structure. The front end of the second conductive element 306 is inserted into the plate-shaped bayonet 307, the middle part is located on the protrusion 309 to form the usage end, and the rear part is located in the receiving groove 308, thereby fixing the second conductive element 306 to the first outer casing 301. The usage end is used for electrical connection with external devices. The first outer casing 301 is provided with a through-hole 305. The second conductive element 306 passes through this through-hole 305 so that one end, i.e., the part with the usage end, protrudes from the surface of the first outer casing 301, while the other end, i.e., the part with the second conductive contact 311, is disposed inside the first outer casing 301. Figure 9 As shown, after the inner shell 102 is inserted into the cavity 304, the cavity formed inside the cavity 304 is a spring receiving cavity.
[0044] Connector application scenario: Using the plug-in structure 300. The plug-in structure 300 is inserted and fixed onto the main body structure 100. The snap-fit portion 101 of the inner housing 102 is located within the receiving portion 303, and the front end face of the elastic arm 302 abuts against the rear end of the snap-fit portion 101. A limit port is provided on the retainer 108, and a step 312 is provided near the front of the cavity 304 of the first outer housing 301. The two cooperate to ensure that the ceramic ferrule 107 can only move back and forth and cannot rotate. After the plug-in structure 300 is fixed onto the main body structure 100, the first conductive contact portion 114 of the first conductive element 110 and the second conductive contact portion 311 of the second conductive element 306 are pressed together to achieve electrical connection.
[0045] At least one of the first conductive contact portion or the second conductive contact portion is disposed on an elastic sheet formed from the corresponding first conductive element or the second conductive element. For example... Figure 6 , Figure 8 and Figure 9As shown, the first conductive contact portion 114 of the first conductive member 110 can be disposed on an elastic sheet formed by bending the first conductive member 110, while the second conductive contact portion can be planar. Or as... Figure 5 As shown, the first conductive contact portion 121 of the first conductive member 110 is planar, and correspondingly, the second conductive contact portion 311 is disposed on the elastic sheet formed by bending the second conductive member 306. That is, at least one conductive sheet forms an elastic structure, so that a stable electrical connection can be formed at the electrical connection point 313.
[0046] like Figure 6 As shown, each second conductive element 306 is configured with a first user end 314 exposed from the corresponding side and a second user end 315 extending to a common surface with the other second conductive element. That is, the two first user ends 314 of the two second conductive elements 306 are located on opposite sides, while the two second user ends 315 are located on the same surface, thus corresponding to two different types of adapters.
[0047] like Figure 11 and Figure 12 As shown, the second housing 316 is fitted onto the first housing 301 to form an SC-type optoelectronic hybrid connector. The second housing 316 has a first exposed opening 317 corresponding to the first user end 314 and a second exposed opening 318 corresponding to the second user end 315. The second housing 316 can move back and forth on the first housing 301, similar to an SC-type connector, thereby enabling unlocking from the adapter. The tail of the second housing 316 can extend to cover the threaded portion 118.
