Abstract
Description
Technical Field
[0001] This application relates to the field of optical fiber connection technology, and in particular to an MT ferrule mating and fixing clip. Background Technology
[0002] The MT ferrule is a key component determining the connection characteristics of a fiber optic connector, typically injection molded from PPS material. With the development of fiber optic communication and data centers, high-speed optical communication modules are essential components in data centers and optical communication networks. MT ferrules and optical fibers, as co-density connection components, are frequently used within these modules, thus increasing the demand for MT ferrules. A typical MT ferrule has a rectangular structure. After processing steps such as fiber threading, adhesive application, curing, grinding, and testing, the MT ferrule is precisely positioned and mated using guide pins to achieve high-precision optical signal transmission.
[0003] In the production and application of optical modules with MT ferrules, the docking and fixing of two MT ferrules is required. Currently, improving the docking and fixing efficiency of MT ferrules is key to optimizing personnel operation efficiency. However, commercially available quick docking and fixing solutions can only be adapted to MT ferrules with a single PIN header size. When faced with the need for customized PIN headers of different sizes, the universality of fixing fixtures cannot be achieved. This limitation not only leads to low personnel operation efficiency but also increases fixture management costs. Utility Model Content
[0004] In order to improve the efficiency of MT ferrule docking and reduce fixture management costs, this application provides an MT ferrule docking fixing clip.
[0005] The MT ferrule docking and fixing buckle provided in this application adopts the following technical solution:
[0006] A locking buckle for MT ferrule docking includes a fixed base mechanism and a slider locking mechanism. The fixed base mechanism includes a fixed base and a reset component. The upper surface of the fixed base has a first slot and a second slot. The slider locking mechanism is slidably connected in the first slot. The slider locking mechanism has a third slot communicating with the second slot. The reset component is disposed in the first slot and has a tendency to move the slider locking mechanism toward the second slot.
[0007] By adopting the above technical solution, during use, the sliding slider locking mechanism moves away from the second slot, initially aligning the two MT inserts to be connected and placing them in the second and third slots respectively. After release, the slider locking mechanism moves towards the second slot under the action of the reset component, causing the two initially connected MT inserts to collide with the inner wall of the second slot, thereby achieving the connection and clamping of the two MT inserts. The overall structure is relatively simple, and the connection of the two MT inserts is convenient and quick, improving the efficiency of MT insert connection and reducing fixture management costs.
[0008] Optionally, the slider buckle mechanism includes a slider upper buckle and a slider fixing seat connected by fixing screws, with a sliding gap between the slider upper buckle and the slider fixing seat, the two sides of the first slot of the fixing base slidingly passing through the sliding gap, and the third slot being provided on the slider upper buckle.
[0009] By adopting the above technical solution, the slider buckle mechanism is divided into a slider upper buckle and a slider fixing seat. This allows the docking fixing buckle of this application to be adaptively replaced with the slider upper buckle according to the size of the MT ferrule, avoiding the waste caused by overall replacement and reducing the fixture management cost.
[0010] Optionally, the reset assembly includes a guide pin, a reset spring, and a locking member. The guide pin is inserted into the fixed base along the sliding direction of the slider latching mechanism. The locking member is disposed on the fixed base to lock the guide pin. The guide pin passes through the latch on the slider. The reset spring is sleeved on the guide pin. One end of the reset spring abuts against the inner wall of the first slot, and the other end of the reset spring abuts against the latch on the slider.
[0011] By adopting the above technical solution, the guide pin can guide the movement of the buckle on the slider, thereby improving the accuracy and stability of the docking; the setting of the clamping part makes it easy to disassemble the guide pin, thus facilitating the replacement of the buckle on the slider; the setting of the return spring provides a return force for the sliding of the slider buckle mechanism, which is simple in structure and easy to use.
[0012] Optionally, the clamping component includes two vertical rods and a horizontal rod connecting the two vertical rods. The fixed base has a slot, the clamping component is inserted into the slot, the guide pin passes through the slot, and the guide pin has an annular groove on its peripheral wall. The two vertical rods are clamped in the annular groove and located on both sides of the guide pin. The minimum distance between the two vertical rods is not greater than the outer diameter of the annular groove section of the guide pin.
[0013] By adopting the above technical solution, when using the device, the guide pin is inserted into the fixed base and then into the slot. Next, the clamping device is inserted into the slot so that the two vertical rods are respectively located in the annular grooves on both sides of the guide pin, thereby clamping the guide pin. When disassembling the guide pin, only the clamping device needs to be pulled out, which is convenient to use.
[0014] Optionally, the fixed base is provided with a through groove along the sliding direction of the slider buckle mechanism.
[0015] By adopting the above technical solution, the through groove facilitates the placement of wires connected to the MT ferrule, avoids interference between wires during the docking process, and thus improves the stability of the MT ferrule docking.
[0016] Optionally, a buffer pad is provided on the side wall of the second slot away from the slider latching mechanism.
[0017] By adopting the above technical solution, the buffer pad can provide buffer protection when the MT ferrule collides with the inner wall of the second slot, reducing the damage to the MT ferrule during the docking process.
[0018] Optionally, the width of the second slot gradually decreases along the sliding direction of the slider latching mechanism from near the slider latching mechanism to far away from the slider latching mechanism.
[0019] By adopting the above technical solution, the width of the second slot gradually decreases from near the slider latching mechanism to far away from the slider latching mechanism along the sliding direction of the slider latching mechanism, which facilitates the smooth entry of the MT insert into the second slot and reduces frictional damage to the MT insert.
[0020] In summary, this application includes at least one of the following beneficial technical effects:
[0021] 1. Initially align the two MT inserts that need to be connected and place them in the second and third slots respectively. After releasing, the slider latching mechanism moves towards the second slot under the action of the reset component, so that the two initially connected MT inserts collide with the inner wall of the second slot, thereby realizing the connection and clamping of the two MT inserts. The overall structure is relatively simple, and the connection of the two MT inserts is convenient and quick, which improves the efficiency of MT insert connection and reduces the cost of fixture management.
[0022] 2. The slider latching mechanism includes a slider upper latch and a slider fixing seat connected by fixing screws, which allows the slider upper latch to be replaced radially according to the size of the MT ferrule to be mated, improving the applicability of the MT ferrule mating fixing latch of this application, while saving production costs and reducing fixture management costs;
[0023] 3. The matching arrangement of guide pin, return spring and clamping component utilizes the elastic force of return spring as the sliding driving force of slider buckle mechanism, which is simple in structure and easy to use; guide pin can guide the movement of buckle on slider to improve the accuracy and stability of docking, while clamping component fixes guide pin, which is convenient for guide pin replacement, thus making it convenient to replace buckle on slider.

[0029] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.
[0030] This application discloses an MT ferrule docking and fixing clip. (Refer to...) Figure 1 The MT ferrule docking and fixing buckle includes a fixing base mechanism and a slider buckle mechanism. The fixing base mechanism includes a fixing base 1 and a reset assembly. The fixing base 1 is generally made of plastic or metal material with certain strength and stability, such as aluminum alloy or high-strength engineering plastic. The upper surface of the fixing base 1 has a first slot 11 and a second slot 12. The first slot 11 is a vertical through slot, and the second slot 12 is a countersunk slot communicating with the first slot 11. The width of the second slot 12 on the side closer to the first slot 11 is greater than the width on the side farther from the first slot 11, and a buffer pad 13 is provided on the side wall of the second slot 12 away from the first slot 11. The fixing base 1 also has a through slot 14 on the horizontal side communicating with the first slot 11 and the second slot 12. The slider latching mechanism is slidably connected to the first slot 11. The slider latching mechanism is provided with a third slot 21 that communicates with the second slot 12. The reset component is disposed in the first slot 11 and has the tendency to move the slider latching mechanism toward the second slot 12.
[0031] In use, the sliding slider locking mechanism moves away from the second slot 12, initially aligning the two MT ferrules to be connected and placing them in the second slot 12 and the third slot 21 respectively. After release, the slider locking mechanism moves towards the second slot 12 under the action of the reset component, causing the two initially aligned MT ferrules to collide with the inner wall of the second slot 12, thus achieving connection and clamping of the two MT ferrules. The overall structure is relatively simple, and the connection of the two MT ferrules is convenient and quick, improving the efficiency of MT ferrule connection and reducing fixture management costs. The buffer pad 13 provides cushioning protection when the MT ferrule collides with the inner wall of the second slot 12, reducing damage to the MT ferrules during connection. The width of the second slot 12 gradually decreases along the sliding direction of the slider locking mechanism from near to far from it, facilitating the smooth entry of the MT ferrule into the second slot 12 and reducing frictional damage to the MT ferrule. The through slot 14 is used to place the wires connected to the MT ferrules, avoiding interference during connection and thus improving the stability of the MT ferrule connection.
[0032] For example, refer to Figure 2 The slider latching mechanism includes a slider upper latch 2 and a slider fixing seat 3 connected by fixing screws 31. A sliding gap 32 is provided between the slider upper latch 2 and the slider fixing seat 3. The two sides of the first slot 11 of the fixing base slide through the sliding gap 32, and the third slot 21 is formed on the slider upper latch 2. The slider upper latch 2 and the slider fixing seat 3 can be made of plastic or metal. The connection by fixing screws 31 ensures that their relative positions are fixed. The size of the sliding gap 32 is designed according to the shape and thickness of the two sides of the first slot 11 to ensure that the slider latching mechanism can slide smoothly in the first slot 11. The third slot 21 is used to cooperate with the second slot 12 to fix the MT insert. Its shape and size are adapted to the MT insert. The slider latching mechanism is divided into a slider upper latch 2 and a slider fixing seat 3. This design allows the locking latch of this application to be replaced according to the size of the MT insert without replacing the slider upper latch 2, avoiding the waste caused by overall replacement and reducing the fixture management cost.
[0033] Specifically, the reset assembly includes a guide pin 4, a reset spring 5, and a locking element 6. The guide pin 4 is inserted into the fixed base 1 along the sliding direction of the slider latching mechanism. The guide pin 4 is cylindrical and generally made of metal, such as stainless steel, possessing high strength and straightness to ensure smooth sliding of the slider latching mechanism. The reset spring 5 is sleeved on the guide pin 4, with one end abutting against the inner wall of the first slot 11 and the other end abutting against the latch 2 on the slider. The reset spring 5 is generally a helical spring, with its elastic coefficient selected according to the required reset force. It provides a tendency for the slider latching mechanism to move towards the second slot 12. The locking element 6 is located on the fixed base 1 and is used to lock the guide pin 4. The guide pin 4 guides the movement of the latch 2 on the slider, thereby improving the accuracy and stability of the connection. The locking element 6 facilitates the disassembly of the guide pin 4, making it convenient to replace the latch 2 on the slider. The reset spring 5 provides a reset force for the sliding of the slider latching mechanism, resulting in a simple structure and easy use.
[0034] Reference Figure 1 and Figure 3 The clamping component 6 includes two vertical rods 61 and a horizontal rod 62 connecting the two vertical rods 61. A slot 15 is provided on the fixed base 1, and the clamping component 6 is inserted into the slot 15. The guide pin 4 is also inserted into the slot 15. An annular groove 41 is provided on the peripheral wall of the guide pin 4. The two vertical rods 61 are clamped within the annular groove 41 and located on both sides of the guide pin 4. The minimum distance between the two vertical rods 61 is not greater than the outer diameter of the annular groove 41 section of the guide pin 4. The clamping component 6 can be made of plastic or metal. The clamping component 6 prevents the guide pin 4 from moving during use. Disassembling the guide pin 4 only requires pulling out the clamping component 6, making it convenient to use.
[0035] The implementation principle of this embodiment is as follows: During use, the compression return spring 5 slides the slider latching mechanism away from the second slot 12, initially aligning the two MT ferrules to be connected and placing them in the second slot 12 and the third slot 21 respectively. Then, the slider latching mechanism is released, and the elastic force of the return spring 5 causes the upper latch 2 of the slider to move towards the second slot 12, thereby causing the two initially connected MT ferrules to collide with the inner wall of the second slot 12, thus achieving the connection and clamping of the two MT ferrules. The overall structure is relatively simple, and the connection of the two MT ferrules is convenient and quick, improving the efficiency of MT ferrule connection and reducing fixture management costs. In addition, since the slider latching mechanism includes the upper latch 2 of the slider and the slider fixing seat 3 connected by the fixing screw 31, the upper latch 2 of the slider can be radially adapted to the size of the MT ferrules to be connected without replacing the slider fixing seat 3, improving the applicability of the MT ferrule connection fixing latch of this application, while saving production costs and reducing fixture management costs.
[0036] The above are all optional 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.
