Description

Technical Field

[0001] This application relates to the field of optoelectronic connectors, and in particular to an SC-type fiber optic active connector with an electrically connected connection. Background Technology

[0002] Fiber optic connectors are passive optical devices that enable active connections between optical fibers. They also have the function of connecting optical fibers to active devices, other passive devices, and systems and instruments.

[0003] Fiber optic cables have the function of high-speed data transmission, but in some cases, it is necessary to transmit data signals (fiber optic) and power supply over long distances (copper wire) simultaneously through optical cables (which become composite optical cables). However, traditional fiber optic mobile connection machines do not have this function, so it needs to be improved. Summary of the Invention

[0004] To enable the active connector to simultaneously transmit data signals and provide power over long distances, this application provides an SC-type fiber optic active connector with an electrical connection.

[0005] The SC-type fiber optic active connector with electrical connection provided in this application adopts the following technical solution: An SC-type fiber optic connector with electrical connection includes a connector and an adapter. The connector includes a connecting base plate, a connecting housing, a connecting baffle, and a connection strength component. The connecting base plate is installed at the bottom of the connecting housing. The connecting baffle is placed inside the connecting housing and connected to one end of the connecting base plate. The connection strength component is connected to the end of the connecting base plate away from the connecting baffle and is disposed at the end of the connecting housing away from the connecting baffle. Copper pavements are provided on the connecting baffle, the connecting base plate, and the connection strength component. The copper pavements are connected to the cable of a composite optical cable to transmit electrical signals. The optical fibers of the composite optical cable pass through the connecting housing and the connection strength component in sequence. The connecting baffle is connected to the adapter, and the adapter transmits electrical and data signals.

[0006] By adopting the above technical solution, the connection strength component is clamped onto the connection housing from the bottom upwards, and then the connection housing and the connection strength component are locked with a pin; the composite optical cable enters the sealed area from the tail of the connection housing. At this time, the optical fiber and the cable are separated. After the optical fiber is separated at the connection baffle, it exits from the front hole of the connection housing and passes through the connection strength component. When the adapter is connected to the connector, the optical fiber enters the adapter through the connection strength component. Meanwhile, after the cable and optical fiber are separated, they are soldered onto the pads of the connecting baffle. The copper pave on the connecting baffle is connected to the copper pave on the connecting base plate. The copper pave on the connecting base plate is connected to the connecting strength component and finally connected to the adapter. The copper pave enables the electrical signal in the composite optical cable to be transmitted to the adapter, and finally enables the active connector to transmit data signals and provide power over long distances at the same time. Electrical connection is achieved by using the locking mechanism between the adapter and connector in traditional fiber optic connectors; copper plating on PCBs can transmit DC, AC and electrical signals, and surface-mount capacitors, ICs and other electronic components can be added to the PCB to achieve expanded functionality.

[0007] Optionally, the adapter includes a first housing, a second housing, and a connecting bracket. The first housing and the second housing are attached to form a channel for inserting a connecting base plate and a connecting housing. The connecting bracket is installed between the first housing and the second housing. The connecting bracket can clamp the connection strength component inserted into the channel and simultaneously transmit electrical signals.

[0008] By adopting the above technical solution, the connection base plate is connected to the connection strength component through copper pouring, and finally connected to the adapter. At this time, the connection frame not only clamps the connection strength component, but also realizes the transmission of electrical signals. This solution utilizes the original adapter structure to establish an electrical connection. Moreover, the adapter itself is a passive device, but it realizes the transmission of electrical signals through electrical connection. Since the structure has not been changed, the adapter in this solution is fully compatible with ordinary SC adapters and can be used interchangeably.

[0009] Optionally, the connecting frame includes a bracket, a conductive buckle, and conductive pins. The bracket is clamped between the first housing and the second housing. The bracket is sleeved on the conductive buckle and fixes the position of the conductive buckle. The conductive buckle engages with the connection strength component and transmits electrical signals simultaneously. The conductive pins pass through the bracket and are connected to the conductive buckle. The end of the conductive pin away from the bracket passes through the first housing and the second housing and protrudes.

[0010] By adopting the above technical solution, the cable passes through the protective hole and is soldered to the pad of the connecting baffle. The copper pour on the connecting baffle is connected to the copper pour on the connecting base plate. The copper pour on the connecting base plate is connected to the connecting strength component, and then connected to the copper pour on the connecting protrusion. When connected to the adapter, the copper pour on the connecting protrusion is connected to the conductive buckle, which realizes the transmission of electrical signals in the composite optical cable to the adapter, and then leads them out to the required position through the conductive pins. By using the conductive pins in conjunction with the original adapter structure, after the electrical signals in the composite optical cable are transmitted to the adapter, the movable connector can simultaneously transmit data signals and provide power over long distances. The locking clips used in typical SC adapters have been changed from plastic to conductive metal, allowing for an electrical connection between the clips and the connector interface during adapter connection. Electrical signals are then routed through conductive pins for easier installation and use.

[0011] Optionally, the connector further includes a connecting outer frame sleeve, the ends of the connecting strength component and the connecting housing being inserted into the connecting outer frame sleeve, and the connecting outer frame sleeve being connected to the adapter.

[0012] By adopting the above technical solution, the connecting outer frame is fitted onto the connecting strength component and the connecting housing, and the connecting outer frame is inserted into the first housing or the second housing to complete the installation of the connector and the adapter; at this time, the connecting outer frame covers the connection between the connecting strength component and the connecting housing, thereby improving the strength of the entire connector.

[0013] Optionally, both the first and second outer shells are provided with positioning slots, and the connecting outer frame is provided with a connecting positioning block, which can be attached to the inner sidewall of the positioning slot.

[0014] By adopting the above technical solution, the connecting frame is inserted into the first or second housing. When the connecting positioning block abuts against the bottom of the positioning through groove, the installation of the connector and adapter is completed. The connecting positioning block can achieve rapid positioning during installation, thus improving installation efficiency.

[0015] Optionally, the outer wall of the connecting outer frame is provided with a connecting limiting protrusion, which limits the position of the connecting outer frame when it is connected to the adapter.

[0016] By adopting the above technical solution, the connecting limiting ring not only plays a limiting role during installation, but also increases the friction with the operator's hand during installation, while improving the deformation resistance of the connecting outer frame when the connecting strength component and the connecting housing are inserted into the connecting outer frame.

[0017] Optionally, the connection strength component has a connection protrusion at one end near the connection housing, and the connection protrusion is also provided with copper pavement for electrical signal transmission.

[0018] By adopting the above technical solution, when connecting with the adapter, the copper plating of the connecting protrusion is connected to the conductive buckle, which realizes the transmission of electrical signals in the composite optical cable to the adapter, and then leads them out to the required position through the conductive pins; the setting of the connecting protrusion increases the contact area between the conductive buckle and the electrical signal connection of the connection strength component, thereby improving the stability of the connection.

[0019] Optionally, the connecting outer frame sleeve has a connecting port on its side wall away from the connecting housing, the connecting strength component is inserted into the connecting outer frame sleeve to the connecting port, and the connecting protrusion extends out from the connecting port.

[0020] By adopting the above technical solution, a larger diameter connection port is pre-opened on the outer frame of the connector. This not only allows the connection protrusion to extend smoothly without requiring the connection strength component to extend out of the outer frame of the connector, but also allows the inner sidewall of the connection port to act as a locking mechanism for the connector housing, further improving the overall assembly strength of the connector.

[0021] Optionally, the connecting baffle is provided with a protective hole for the cable to pass through.

[0022] By adopting the above technical solution, the inner wall of the protective hole supports the cable and positions it, while reducing the copper laying area.

[0023] In summary, this application includes at least one of the following beneficial technical effects: 1. After the cable and optical fiber are separated, they are soldered onto the pads of the connecting baffle. The copper pave on the connecting baffle is connected to the copper pave on the connecting base plate. The copper pave on the connecting base plate is connected to the connecting strength component and finally connected to the adapter. The copper pave is used to transmit the electrical signal in the composite optical cable to the adapter, and finally the active connector can transmit data signals and provide power over long distances at the same time. 2. The cable passes through the protective hole and is soldered to the pads of the connecting baffle. The copper pour on the connecting baffle is connected to the copper pour on the connecting base plate, and the copper pour on the connecting base plate is connected to the connecting strength component, which in turn connects to the copper pour on the connecting protrusion. When connected to the adapter, the copper pour on the connecting protrusion connects to the conductive clip, enabling the electrical signal in the composite optical cable to be transmitted to the adapter, and then led out to the required position through the conductive pins. Through the structure of the conductive pins in conjunction with the original adapter, after the electrical signal in the composite optical cable is transmitted to the adapter, the movable connector can simultaneously transmit data signals and provide power over long distances. 3. When connected to the adapter, the copper plating of the connecting protrusion connects with the conductive clip, enabling the electrical signals in the composite optical cable to be transmitted to the adapter, and then led out to the required position through the conductive pins; the setting of the connecting protrusion increases the contact area between the conductive clip and the electrical signal connection of the connection strength component, thereby improving the stability of the connection.

[0030] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail.

[0031] This application discloses an SC-type fiber optic active connector with an electrically connected interface. (Refer to...) Figure 1 The SC type fiber optic active connector with electrical connection includes connector 1 and adapter 2. Composite optical cable 3 is connected to connector 1, and connector 1 is connected to adapter 2, so that the data signal and electrical signal of composite optical cable 3 are transmitted simultaneously.

[0032] Reference Figure 2 and Figure 3 The connector 1 includes a connecting housing 12, which is a rectangular cylinder with openings at the top and bottom formed by four plastic plates. A connecting base plate 11 is snapped into one end of the connecting housing 12. The connecting base plate 11 is a PCB board. A cover plate 111 is snapped into the other end. The connecting base plate 11, the connecting housing 12 and the cover plate 111 form a sealed area. Copper plating is provided on the connecting base plate 11. Holes for the composite optical cable 3 to pass through are opened on the narrower side walls of the connecting housing 12. The composite optical cable 3 is inserted into the sealed area from one end of the connecting housing 12.

[0033] Reference Figure 2 and Figure 3 The connecting housing 12 has a connecting baffle 13 snapped into it. The connecting baffle 13 is made by PCB (printed circuit board) technology. There are two copper-plated circuits on the PCB board that are not electrically connected (to realize the positive and negative terminals of power supply). By soldering, it can be soldered to the copper conductor in the composite optical cable to meet the tensile strength requirements of the connector and the optical cable.

[0034] Reference Figure 2 and Figure 3 The connecting baffle 13 is attached to the connecting base plate 11. The copper plating on the connecting baffle 13 and the copper plating on the connecting base plate 11 are soldered together. The connecting baffle 13 is located at one end of the connecting housing 12 near the composite optical cable 3. A protective hole 131 is provided on the connecting baffle 13 for the cable 31 to pass through.

[0035] At this point, the composite optical cable 3 inserted into the connecting housing 12 separates, with part of cable 31 passing through the protective hole 131 and part of optical fiber 32 passing through the connecting baffle 13.

[0036] Reference Figure 2 and Figure 3 The connecting housing 12 also contains a ceramic ferrule 121 and a tailstock 122, which are connected together. A spring 123 is fitted onto the tailstock 122, and a stop 124 abuts against the end of the tailstock 122 away from the ceramic ferrule 121. The stop 124 is pressed against the spring 123 and is engaged with the connecting housing 12. The end of the ceramic ferrule 121 away from the stop 124 exits from the end of the connecting housing 12 away from the connecting baffle 13. At this time, the optical fiber 32 from the connecting baffle 13 passes through the stop 124 and the tailstock 122 and finally exits from the ceramic ferrule 121.

[0037] Reference Figure 2 and Figure 3 A connection strength component 14 is provided at one end of the connecting housing 12 away from the connecting baffle 13. The connection strength component 14 is made of several stacked PCB boards, and the two side walls of the connection strength component 14 are integrally formed with connection protrusions 141.

[0038] Reference Figure 2 and Figure 3 Both the connection strength component 14 and the connection protrusion 141 are provided with copper plating, just like the connection base plate 11. The interface parts and the copper plating on the connection base plate 11 can be soldered to achieve the conduction of electrical signals. Copper plating can transmit DC power, AC power and electrical signals, and can also add surface-mount capacitors, ICs and other electronic components on the PCB to realize expanded functions.

[0039] Reference Figure 3 and Figure 4 The connecting strength component 14 is also fitted with a connecting outer frame sleeve 15. The outer wall of the connecting outer frame sleeve 15 is provided with a number of connecting limiting protrusions 152. The number of connecting limiting protrusions 152 are uniformly and integrally formed on the end of the connecting outer frame sleeve 15 near the connecting housing 12. The side wall of the connecting outer frame sleeve 15 away from the connecting housing 12 is provided with a connecting port 153.

[0040] When the connection strength component 14 and the connection housing 12 are inserted together into the connection outer frame sleeve 15, the connection point between the connection strength component 14 and the connection housing 12 is located at the connection port 153. At this time, the connection protrusion 141 extends out from the connection port 153; the end of the ceramic ferrule 121 protrudes from the end of the connection outer frame sleeve 15 away from the connection housing 12.

[0041] Reference Figure 4 and Figure 5 The adapter 2 includes a first outer shell 21 and a second outer shell 22. The first outer shell 21 and the second outer shell 22 are attached and fixed together. Both the first outer shell 21 and the second outer shell 22 are cylindrical bodies with openings at both ends. That is, the first outer shell 21 and the second outer shell 22 are attached together to form a channel for inserting the connecting base plate 11 and the connecting housing 12.

[0042] Reference Figure 4 and Figure 5 A connecting frame 23 is provided between the first outer shell 21 and the second outer shell 22. The connecting frame 23 includes a plastic bracket 231, on which conductive buckles are snapped. The conductive buckles are made of a conductive material, such as copper or a copper alloy. The conductive buckles are symmetrically arranged, and the bracket 231 is positioned in the middle of the symmetrical conductive buckles. (Refer to...) Figure 4 and Figure 5 The bracket 231 is also provided with conductive pins 233, which can be made of conductive material, such as copper. One end of the conductive pin 233 is connected to a conductive buckle, and the other end extends out of the bracket 231. When the first housing 21 and the second housing 22 clamp the bracket 231, the end of the conductive pin 233 away from the bracket 231 protrudes through the first housing 21 and the second housing 22.

[0043] Reference Figure 4 and Figure 5 Both the first outer shell 21 and the second outer shell 22 are provided with positioning slots 211, and the connecting outer frame 15 is integrally formed with a connecting positioning block 151. The connecting outer frame 15 is inserted from the port of the first outer shell 21 or the second outer shell 22. When the connecting positioning block 151 abuts against the bottom of the positioning slot 211, the installation of the connector 1 and the adapter 2 is completed. At this time, the conductive buckle clamps the connecting outer frame 15. When the conductive buckle reaches the connecting protrusion 141, the conductive buckle is in contact with the side wall of the connecting protrusion 141, and the conductive buckle and the connecting protrusion 141 are connected.

[0044] At this time, the optical fiber 32 that passes through the ceramic ferrule 121 is connected to the required optical connector in the adapter 2 to transmit the signal. The electrical signal of the cable 31 is output to the conductive buckle through the copper plating of the connecting baffle 13, the connecting base plate 11, the connecting strength component 14 and the connecting protrusion 141, and then transmitted to the conductive pin 233 by the conductive buckle. Finally, it is led out to the required position through the conductive pin 233.

[0045] The implementation principle of an SC-type fiber optic movable connector with electrical connection according to an embodiment of this application is as follows: the connection strength component 14 is clamped onto the connection housing 12 from below, and then the connection housing 12 and the connection strength component 14 are locked together using a pin; the composite optical cable 3 passes through the sealing area from the tail of the connection housing 12, at which point the optical fiber 32 and the cable 31 separate. After the optical fiber 32 is separated at the connection baffle 13, it passes through the stop, the tailstock 122 and the ceramic ferrule 121 to the front end hole of the connection housing 12, and then passes through the connection strength component. 14; At this time, use the stop to cover the ceramic ferrule 121 and the tailstock 122, and push it in along the axial direction of the housing hole after contacting the spring 123, until the two sides of the stop are inserted into the slots on both sides of the housing to complete the installation; cover the cover plate 111 on the connecting housing 12, put the connecting outer frame sleeve 15 on the connecting strength component 14 and the connecting housing 12, insert the connecting outer frame sleeve 15 into the first housing 21 or the second housing 22, and when the connecting positioning block 151 abuts against the bottom of the positioning through groove 211, the installation of the connector 1 and the adapter 2 is completed.

[0046] At this time, the cable 31 passes through the protective hole 131 and is soldered to the pad of the connecting baffle 13. The copper pour on the connecting baffle 13 is connected to the copper pour on the connecting base plate 11. The copper pour on the connecting base plate 11 is connected to the connecting strength component 14, and then connected to the copper pour on the connecting protrusion 141. When connected to the adapter 2, the copper pour on the connecting protrusion 141 is connected to the conductive buckle, so that the electrical signal in the composite optical cable 3 can be transmitted to the adapter 2, and then led out to the required position through the conductive pin 233.

[0047] By utilizing copper plating and conductive clips, the active connector 1 can simultaneously transmit data signals and provide power over long distances.

[0048] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
