Description

Technical Field

[0002] Coupling fixtures provide a stable physical connection between optical modules and PCB circuit boards. They firmly fix the optical modules to the PCB circuit boards, preventing displacement or detachment due to external vibrations, impacts, or other factors. However, existing coupling fixtures can exert significant stress on the fiber optic array connectors during coupling, causing deformations such as bending or stretching, thereby increasing optical signal loss and affecting the forward transmission efficiency of the optical signal.

[0072] Example 1

[0073] Please see Figure 1-5 Specifically, in this embodiment of the coupling fixture, the coupling fixture provided in this application is used to stably couple a fiber optic array connector onto a PCB circuit board. It specifically includes a base, a sliding assembly, a flange, a first snap-fit ​​assembly, and a second snap-fit ​​assembly. The base includes a first platform and a second platform connected to the first platform. The top of the first platform has a first mounting area, and the top of the second platform has a fixing area adapted to the PCB circuit board. The fixing member of the sliding assembly is fixedly disposed within the first mounting area. The flange is fixedly connected to the sliding member of the sliding assembly, and the flange is detachably connected to the first end of the fiber optic array connector. The first snap-fit ​​assembly is disposed at the top edge of the first side of the second platform, and has a first slot adapted to the second end of the fiber optic array connector. The second snap-fit ​​assembly is disposed at the top edge of the second side of the second platform, and has a second slot adapted to the third end of the fiber optic array connector. The height of the first platform is less than the height of the second platform. The sliding member of the sliding assembly slides relative to the fixing member in a direction close to or away from the second platform. Both the first and second sides are parallel to the central axis of the base.

[0074] Specifically, this utility model provides a coupling clamp for stably coupling a fiber optic array connector to a PCB circuit board. It includes a base, a sliding assembly, a flange, a first snap-fit ​​assembly, and a second snap-fit ​​assembly. The base includes a first platform and a second platform connected to the first platform. The top of the first platform has a first mounting area, and the top of the second platform has a fixing area adapted to the PCB circuit board. The fixing member of the sliding assembly is fixedly disposed within the first mounting area. The flange is fixedly connected to the sliding member of the sliding assembly, and the flange is detachably connected to the first end of the fiber optic array connector. The first snap-fit ​​assembly is disposed at the top edge of the first side of the second platform, and has a first slot adapted to the second end of the fiber optic array connector. The second snap-fit ​​assembly is disposed at the top edge of the second side of the second platform, and has a second slot adapted to the third end of the fiber optic array connector. The height of the first platform is less than the height of the second platform. The sliding member of the sliding assembly slides relative to the fixing member in a direction close to or away from the second platform. Both the first and second sides are parallel to the central axis of the base. The coupling fixture provided in this application has a sliding component on the base, and the fiber optic array connector is detachably connected between the snap-fit ​​component and the flange. The flange is fixed to the slider. During the process of coupling the second or third end of the fiber optic array connector to the PCB circuit board, the second or third end of the fiber optic array connector will move back and forth or left and right. At this time, since the first end of the fiber optic array connector is fixed to the slider by the flange, the first end of the fiber optic array connector can slide axially relative to the slide rail. Therefore, when adjusting the second or third end of the fiber optic array connector, the first end can move based on the slide rail without causing stress or deformation to the fiber optic cable connected between the two, which can improve the signal transmission efficiency and the accuracy of signal transmission.

[0075] In one possible implementation, the sliding assembly includes a slide rail and a slider. The slide rail is fixedly installed in the first installation area and is a fixed component. The slider is movably disposed within the slide rail and is a sliding component. The flange and the slider are detachably connected, which facilitates disassembly and installation in case of flange damage or other flange replacement. However, under normal circumstances, the flange and the slider are locked.

[0076] That is, the first end of the fiber array connector connected to the flange can move axially relative to the slide rail to avoid tensile deformation of the fiber array connector. Here, the axial direction is the direction of moving closer to or away from the second platform.

[0077] In one possible implementation, the sliding component further includes a limiting block, which is fixedly disposed at the end of the slide rail away from the second platform, so as to limit the slider that is movably disposed on the slide rail and prevent the slider from sliding out of the slide rail.

[0078] In one possible implementation, such as Figure 3 As shown, the fiber optic array connector includes a TX glass substrate, an RX glass substrate, and an MT head. The RX glass substrate includes a first glass substrate and a first fiber array. One end of the first fiber array is connected to the first glass substrate, and the other end of the first fiber array is connected to one fiber array of the MT head. The TX glass substrate includes a second glass substrate and a second fiber array. One end of the second fiber array is connected to the second glass substrate, and the other end of the second fiber array is connected to another fiber array of the MT head. The MT head is the first end of the fiber optic array connector, the first glass substrate is the second end of the fiber optic array connector, and the second glass substrate is the third end of the fiber optic array connector.

[0079] The MT head mates with the flange, and the first glass substrate is detachably connected to the first snap-fit ​​assembly, while the second glass substrate is detachably connected to the second snap-fit ​​assembly. Generally, the first glass substrate is rectangular, and the second glass substrate is parallelogram-shaped. Therefore, two snap-fit ​​assemblies with different slot shapes are required. The first slot formed by the first snap-fit ​​assembly matches the shape of the first glass substrate, and the second slot formed by the second snap-fit ​​assembly matches the shape of the second glass substrate. This limits the position of the fiber optic array connector, facilitating the limiting of the first glass substrate by the first slot and the limiting of the second glass substrate by the second slot. This allows for easy coupling of the first and second glass substrates to their corresponding coupling points on the PCB circuit board.

[0080] In one possible implementation, the first snap-fit ​​assembly includes a first connecting block, a first fixing block, a first push plate, and a first spring. The first connecting block and the first fixing block are connected to form an L-shaped structure. The first connecting block is located at the top edge of the first side of the second platform. The first fixing block is fixed to the side wall of the first side by a nut. A first channel is provided through the first connecting block in a direction perpendicular to the first side. A first edge groove communicating with the first channel is formed on the top edge of the first connecting block near the fixing area. The first push plate passes through the first channel. A first rectangular through groove is formed in the middle part of the portion of the first push plate away from the fixing area. A first connecting rod is provided in the first rectangular through groove. The first spring is sleeved on the first connecting rod and abuts against the first connecting block. First limiting posts are provided on both sides of the top of the first push plate near the fixing area. The first limiting posts abut against the first connecting block under the action of the first spring. When the first push plate moves towards the fixing area, a first snap-fit ​​groove is formed between the first limiting posts, the first push plate, and the first connecting block. The shape of the formed first snap-fit ​​groove is adapted to the shape of the first glass substrate and is rectangular.

[0081] Specifically, when the first push plate is pushed towards the fixed area, it compresses the first spring, causing further deformation. At this time, the first limiting post separates from the first connecting block, forming a gap between them, i.e., the first slot. The first glass substrate can then be engaged into this first slot for positioning. Figure 4 As shown.

[0082] Furthermore, since a first adjustment groove is also provided through the first fixing block, one end of the nut passes through the first adjustment groove and is threadedly connected to the first side surface, while the other end of the nut presses the first fixing block against the first side surface. The first adjustment groove is opened axially, so that when the nut is loosened, the first fixing block can be adjusted in position along the axial direction, making it easier for the first glass substrate, which is engaged therein, to find the corresponding coupling point on the PCB circuit board.

[0083] In one possible implementation, the second snap-fit ​​assembly includes a second connecting block, a second fixing block, a second push plate, and a second spring. The second connecting block and the second fixing block are connected to form an L-shaped structure. The second connecting block is located at the top edge of the second side of the second platform. The second fixing block is fixed to the side wall of the second side by a nut. A second channel is provided through the second connecting block in a direction perpendicular to the second side. A second groove communicating with the second channel is formed on the top edge of the second connecting block near the fixing area. The second push plate passes through the second channel. A second rectangular through slot is formed in the middle of the portion of the second push plate away from the fixing area. A second connecting rod is provided in the second rectangular through slot. The second spring is sleeved on the second connecting rod and abuts against the second connecting block. Second limiting posts are provided on both sides of the top of the second push plate near the fixing area. The second limiting posts abut against the second connecting block under the action of the second spring. When the second push plate moves towards the fixing area, a second snap-fit ​​groove is formed between the second limiting posts, the second push plate, and the second connecting block. The shape of the formed second snap-fit ​​groove is adapted to the shape of the second glass substrate and is a parallelogram.

[0084] Specifically, when the second push plate is pushed towards the fixed area, the second spring is compressed, causing further deformation of the second spring. At this time, the second limiting post separates from the second connecting block, forming a gap between them, i.e., the second slot. The second glass substrate can then be engaged into this second slot for positioning. Figure 4 As shown.

[0085] Furthermore, a groove can be made on the top of both the first connecting block and the second connecting block near the fixed area to facilitate the removal of the glass substrate that is snapped into the groove.

[0086] In one possible implementation, a second adjusting groove is provided through the second fixing block. One end of a nut passes through the second adjusting groove and is threadedly connected to the second side surface. The other end of the nut abuts the second fixing block against the second side surface. The second adjusting groove is axially oriented, allowing the second fixing block to be adjusted axially when the nut is loosened. This facilitates the second glass substrate, which is engaged therein, to locate the corresponding coupling point on the PCB circuit board. Figure 5 The diagram shows the structure of the first glass substrate and the second glass substrate coupled to the PCB circuit board.

[0087] In one possible implementation, a second mounting area is provided on the side wall of the second platform, the second mounting area is connected to the fixed area, and the coupling fixture also includes a locking component, which is disposed at the second mounting area and rotatably connected to the side wall of the second platform.

[0088] In one possible implementation, the locking assembly includes a rotating head, a rectangular limiting block, and a rotating component. The rotating head is fixedly disposed at one end of the rotating component, and the other end of the rotating component passes through the rectangular limiting block and is rotatably connected to the second platform. The rotating component is threadedly connected to the rectangular limiting block, and the width of the second installation area is adapted to the width of the rectangular limiting block.

[0089] Specifically, a locking assembly is used to lock and limit the PCB circuit board placed in a fixed area. The rotating component is only rotatably connected to the second platform but does not move relative to it.

[0090] One possible implementation is that the locking assembly can include a rotating head, a rectangular limiting block, and a rotating component. Since the rectangular limiting block is adapted to the size of the installation area and cannot rotate, and the rotating component is threadedly connected to the rectangular limiting block, rotating the rotating component will drive the rectangular limiting block to move closer to or away from the rotating head, thereby limiting and locking it against the side edge of the PCB circuit board.

[0091] Example 2

[0092] This utility model also provides a coupling component, which includes a fiber array connector and a coupling fixture as described in any one of the embodiments, wherein the fiber array connector is detachably fixed to the coupling fixture.

Through their combined action, the fiber optic array connector is easily coupled and connected to the PCB circuit board.
