Description

Technical Field

[0001] This utility model relates to the field of connection interface technology, and in particular to an anti-interference, high-stability optical module connection interface. Background Technology

[0002] In optical communication systems, the optical module connection interface is the core component that enables signal transmission between the optical module and the device motherboard and optical fiber link. Through mechanical docking and electrical / optical coupling, it ensures efficient conversion and transmission of optical signals and electrical signals, and is widely used in scenarios such as data centers, 5G base stations, and fiber broadband networks.

[0003] However, existing optical module connection interfaces are usually exposed to the environment, and dust easily accumulates on the interfaces, leading to increased interface wear, affecting the sealing and mechanical positioning accuracy of the interfaces, causing the interface connections to loosen, and affecting the stability of the interface connections. Utility Model Content

[0004] Therefore, the purpose of this utility model is to propose an anti-interference, high-stability optical module connection interface to solve the problems mentioned in the background art and overcome the shortcomings of the existing technology.

[0005] To achieve the above objectives, one embodiment of this utility model provides an anti-interference, high-stability optical module connection interface, including an interface housing fixedly connected to an optical module. The interface housing has a guide rail inside for guiding the insertion of the optical module. One end of the interface housing is rotatably connected to a movable baffle for shielding and protecting the connection. An elastic sheet is fixedly installed inside the movable baffle to close its sides. A locking piece is fixedly installed at one end of the movable baffle for positioning. A fastening spring is provided on one side of the movable baffle to press and fix the interior of the interface housing. A waterproof sealing ring is provided on one side of the fastening spring to seal the interface housing. A dustproof fixing piece is provided on one side of the waterproof sealing ring to fix it.

[0006] Preferably, one end of the interface housing is provided with a rotating groove for supporting the movable baffle, one side of the rotating groove is provided with a cross locking groove for engaging the locking plate, both ends of the interface housing are provided with fastening connection grooves for installing dustproof fixing plates, and the inside of the guide rail is provided with a guide groove for guiding.

[0007] The above technical solution is adopted as follows: the rotating groove at one end of the interface housing (zinc alloy die casting, nickel plated) is rotatably connected to the movable baffle through a pin, providing stable support for the baffle. The cross-shaped locking groove (the cross-sectional size is adapted to the locking block) on one side of the rotating groove is arranged in a cross shape. By engaging with the locking plate, the movable baffle is accurately positioned in the "open" and "closed" positions. The fastening connecting grooves at both ends are interference-fitted with the bosses of the dustproof fixing plate to ensure that the dustproof plate is not loose after installation. The guide groove inside the guide rail is clearance-fitted with the guide boss of the optical module plug to guide the optical module to be inserted and removed in a straight line, avoiding pin misalignment and damage.

[0008] Preferably, either of the above embodiments has mounting grooves at both ends of the movable baffle for fixing the elastic sheet, and the movable baffle has an adjustment groove inside for guiding the locking piece.

[0009] The above technical solution is adopted: the mounting grooves at both ends of the movable baffle (ABS material) (the width of which is adapted to the elastic sheet) are fixed to the elastic sheet with glue to ensure that the sheet moves synchronously when the baffle rotates. The internal adjustment groove (the width of which is larger than that of the locking block) provides the locking block of the locking plate with room to move, allowing the locking block to slide along the axial direction of the groove while limiting its radial offset, ensuring precise engagement with the cross locking groove. When the baffle rotates, the adjustment groove guides the locking block to compress or release the high-strength spring, so as to realize the smooth opening and closing and reliable locking of the baffle.

[0010] Preferably, in any of the above embodiments, the elastic sheet includes a fastening sleeve made of a highly elastic material and a fastening clip for clamping. The fastening sleeve is fixedly installed inside the movable baffle, and a fastening clip located on one side of the movable baffle is fixedly installed at one end of the fastening sleeve.

[0011] The above technical solution is adopted: the fastening sleeve (made of silicone rubber) is inserted into the mounting groove of the movable baffle through an interference fit, and one end of it is vulcanized to fix the fastening clip (beryllium copper strip). When the movable baffle is closed and the optical module is inserted, the fastening clip adheres to the outer wall of the optical module cable under the elastic force of the fastening sleeve, forming a radial clamping, which not only enhances the cable's pull-out resistance, but also prevents dust from entering through the double seal of the sleeve and the clip. When the cable is inserted or removed, the elastic deformation of the sleeve can adapt to the fluctuation of the cable diameter and maintain a stable clamping force.

[0012] Preferably, in any of the above embodiments, the locking plate includes a high-strength spring for support and a locking block for locking the movable baffle. The high-strength spring is fixedly installed inside the movable baffle, and one end of the high-strength spring is fixedly installed with a locking block that moves inside the movable baffle.

[0013] The above technical solution involves a high-strength spring pre-compressed inside the movable baffle. Its elasticity pushes the locking block (POM material) out of the baffle surface. When the movable baffle rotates to the "closed" or "open" position, the conical surface of the locking block head contacts the cross locking groove, compressing the spring. After the baffle is in place, the spring resets and pushes the locking block into the groove, achieving mechanical locking. When unlocking, an external force is applied to rotate the baffle, and the groove wall presses the conical surface of the locking block to retract it. The spring stores energy until the baffle rotates to another position and locks again, forming a "rotation-unlocking-positioning-locking" cycle mechanism.

[0014] Preferably, in any of the above solutions, the fastening spring is configured as an arc-shaped structure, the fastening spring is fixedly installed inside the interface housing, and the waterproof sealing ring is fixedly installed at one end of the interface housing.

[0015] The above technical solution is adopted: the fastening spring (phosphor bronze strip) is fixed in an arc shape inside the interface housing. After the optical module is inserted, the spring is squeezed and generates elastic deformation, forming a radial preload force, which makes the optical module fit tightly with the interface housing, offsetting poor contact caused by vibration. The waterproof sealing ring (nitrile rubber) is embedded in the annular groove at the end of the interface housing, and fits with the outer shell of the optical module to form an axial seal, preventing liquid from entering along the insertion and removal gap.

[0016] Preferably, in any of the above embodiments, the dustproof fixing piece includes a dustproof piece for bonding and fixing and a fixing pad for fastening it. The dustproof piece is snapped into the inside of the interface housing. The dustproof piece is bonded to the waterproof sealing ring. One end of the dustproof piece is provided with a boss for engaging it. The two ends of the boss are fixedly connected with fixing pads for squeezing and fastening it.

[0017] The above technical solution is adopted: the dustproof sheet (stainless steel mesh) is snapped into the fastening connection groove of the interface housing, and its edge is tightly fitted with the waterproof sealing ring to form a double barrier of "rubber ring-filter". The filter intercepts dust particles larger than a certain size, and the rubber ring blocks fine dust and water vapor. The boss at one end of the dustproof sheet is inserted into the fastening connection groove. The fixing rubber pads (neoprene rubber) at both ends of the boss are squeezed by the groove wall and produce elastic deformation. The reaction force fastens the dustproof sheet to avoid vibration and loosening, while compensating for assembly tolerances to ensure reliable sealing.

[0018] Compared with the prior art, the advantages and beneficial effects of this utility model are as follows:

[0019] 1. A movable baffle that can be rotated and adjusted is provided at the connection entry end of the interface housing of the optical module connection interface. The movable baffle is used to seal the entry end of the interface housing, and by rotating the movable baffle, it can provide a certain degree of shielding and protection for the optical fiber link connected to the connection interface. At the same time, a dustproof fixing piece and a waterproof sealing ring that fit with the movable baffle are provided on the inside of the interface housing to achieve overall sealing of the interface housing, preventing the connection interface from being directly exposed, effectively reducing dust adhesion, and improving the safety and stability of the connection interface.

[0020] 2. Adjustable elastic tabs are installed at both ends of the movable baffle. The elasticity of the tabs can clamp and fix the fiber optic link inserted into the connection interface, further enhancing the stability of the connection interface and reducing the impact of loose connection.

Detailed Implementation

[0029] The present invention will be further described below with reference to the accompanying drawings, but the scope of protection of the present invention is not limited to the following description.

[0030] like Figure 1-5 As shown, the anti-interference high-stability optical module connection interface of this utility model embodiment includes an interface housing 1 fixedly connected to the optical module. The interface housing 1 is provided with a guide rail 2 for guiding the insertion of the optical module. One end of the interface housing 1 is rotatably connected to a movable baffle 3 for shielding and protecting the connection. An elastic sheet 4 for sealing its side is fixedly installed inside the movable baffle 3. A locking piece 5 for positioning is fixedly installed at one end of the movable baffle 3. A fastening spring 6 for pressing and fixing the inside of the interface housing 1 is provided on one side of the movable baffle 3. A waterproof sealing ring 7 for sealing the interface housing 1 is provided on one side of the fastening spring 6. A dustproof fixing piece 8 for fixing the waterproof sealing ring 7 is provided on one side of the waterproof sealing ring 7.

[0031] Preferably, one end of the interface housing 1 is provided with a rotating groove for supporting the movable baffle 3, one side of the rotating groove is provided with a cross locking groove for engaging the locking piece 5, both ends of the interface housing 1 are provided with fastening connection grooves for installing the dustproof fixing piece 8, and the inside of the guide rail 2 is provided with a guide groove 9 for guiding.

[0032] The above technical solution is adopted: the rotating groove at one end of the interface housing 1 (zinc alloy die casting, nickel plated) is rotatably connected to the movable baffle 3 through a pin, providing stable support for the baffle. The cross locking groove (the cross-sectional size is adapted to the locking block 52) on one side of the rotating groove is arranged in a cross shape. By engaging with the locking piece 5, the movable baffle 3 is accurately positioned in the "open" and "closed" positions. The fastening connecting grooves at both ends are interference-fitted with the boss of the dustproof fixing piece 8 to ensure that the dustproof piece 81 is not loose after installation. The guide groove 9 inside the guide rail 2 is clearance-fitted with the guide boss of the optical module plug to guide the optical module to be inserted and removed in a straight line, avoiding pin misalignment and damage.

[0033] Preferably, the movable baffle 3 has mounting grooves at both ends for fixing the elastic sheet 4, and the movable baffle 3 has an adjustment groove inside for guiding the locking piece 5.

[0034] The above technical solution is adopted: the mounting grooves at both ends of the movable baffle 3 (ABS material) (the width of which is adapted to the elastic sheet 4) are fixed to the elastic sheet 4 with glue to ensure that the sheet moves synchronously when the baffle rotates. The internal adjustment groove (the width of which is larger than that of the locking block 52) provides the locking block 52 of the locking piece 5 with a movable space, allowing the locking block to slide along the axial direction of the groove while limiting its radial offset, ensuring precise engagement with the cross locking groove. When the baffle rotates, the adjustment groove guides the locking block to compress or release the high-strength spring 51, so as to realize the smooth opening and closing and reliable locking of the baffle.

[0035] Preferably, in any of the above embodiments, the elastic sheet 4 includes a fastening sleeve 41 made of a highly elastic material and a fastening clip 42 for clamping. The fastening sleeve 41 is fixedly installed inside the movable baffle 3, and a fastening clip 42 located on one side of the movable baffle 3 is fixedly installed at one end of the fastening sleeve 41.

[0036] The above technical solution is adopted: the fastening sleeve 41 (made of silicone rubber) is inserted into the mounting groove of the movable baffle 3 by interference fit, and one end of it is vulcanized to fix the fastening clip 42 (beryllium copper strip). When the movable baffle 3 is closed and the optical module is inserted, the fastening clip 42 adheres to the outer wall of the optical module cable under the elastic force of the fastening sleeve 41, forming radial clamping, which not only enhances the cable's pull-out resistance, but also prevents dust from entering through the double seal of the sleeve and the clip. When the cable is inserted or removed, the elastic deformation of the sleeve can adapt to the fluctuation of the cable diameter and maintain stable clamping force.

[0037] Preferably, in any of the above embodiments, the locking piece 5 includes a high-strength spring 51 for support and a locking block 52 for locking the movable baffle 3. The high-strength spring 51 is fixedly installed inside the movable baffle 3, and one end of the high-strength spring 51 is fixedly installed with the locking block 52 that moves inside the movable baffle 3.

[0038] The above technical solution is adopted: a high-strength spring 51 is pre-compressed and installed inside the movable baffle 3. Its elasticity pushes the locking block 52 (POM material) to extend out of the baffle surface. When the movable baffle 3 rotates to the "closed" or "open" position, the conical surface of the locking block head contacts the cross locking groove and is compressed by the spring. After the baffle is in place, the spring resets and pushes the locking block into the groove to achieve mechanical locking. When unlocking, an external force is applied to rotate the baffle, and the groove wall presses the conical surface of the locking block to retract it. The spring stores energy until the baffle rotates to another position and locks again, forming a "rotation-unlocking-positioning-locking" cycle mechanism.

[0039] Preferably, in any of the above solutions, the fastening spring 6 is configured as an arc-shaped structure, the fastening spring 6 is fixedly installed inside the interface housing 1, and the waterproof sealing ring 7 is fixedly installed at one end of the interface housing 1.

[0040] The above technical solution is adopted: the fastening spring 6 (phosphor bronze strip) is fixed in an arc shape inside the interface housing 1. After the optical module is inserted, the spring is squeezed and generates elastic deformation, forming a radial preload force, so that the optical module and the interface housing fit tightly together, which can offset the poor contact caused by vibration. The waterproof sealing ring 7 (nitrile rubber) is embedded in the annular groove at the end of the interface housing 1 and fits with the outer shell of the optical module to form an axial seal, preventing liquid from entering along the insertion and removal gap.

[0041] Preferably, the dustproof fixing piece 8 includes a dustproof piece 81 for bonding and fixing and a fixing pad 82 for fastening it. The dustproof piece 81 is snapped into the inside of the interface housing 1. The dustproof piece 81 is bonded to the waterproof sealing ring 7. One end of the dustproof piece 81 is provided with a boss for snapping it in. The two ends of the boss are fixedly connected to the fixing pad 82 for squeezing and fastening it.

[0042] The above technical solution is adopted: the dustproof sheet 81 (stainless steel mesh) is engaged in the fastening connection groove of the interface housing 1, and its edge is tightly fitted with the waterproof sealing ring 7 to form a double barrier of "rubber ring-filter". The filter intercepts dust particles larger than a certain size, and the rubber ring blocks fine dust and water vapor. The boss at one end of the dustproof sheet is inserted into the fastening connection groove. The fixing rubber pads 82 (neoprene rubber) at both ends of the boss are squeezed by the groove wall and produce elastic deformation. The reaction force fastens the dustproof sheet to avoid vibration and loosening, while compensating for assembly tolerances to ensure reliable sealing.

[0043] The working principle of the anti-interference, high-stability optical module connection interface of this utility model is as follows:

[0044] When the optical module is inserted, it is inserted and removed along the guide groove 9 of the guide rail 2 inside the interface housing 1. The guide groove 9 guides the optical module to accurately align and avoids damage to the pins. The movable baffle 3 can rotate around the rotating groove of the interface housing 1. When rotating, its internal adjusting groove guides the locking block 52 of the locking piece 5 to compress the high-strength spring 51. When the baffle rotates to the target position, the high-strength spring 51 resets and pushes the locking block 52 into the cross locking groove to achieve positioning. When the movable baffle 3 is closed, the elastic plates 4 at both ends move with the baffle, and the fastening rubber sleeve 41 drives the fastening clamp 4. 2. The optical module cable is attached to the interface housing 1, and the cable is clamped by elastic force to enhance stability. At the same time, the arc-shaped fastening spring 6 inside the interface housing 1 is squeezed by the optical module to generate elastic force, ensuring that the optical module fits tightly. The waterproof sealing ring 7 forms an axial seal with the optical module shell. The dustproof plate 81 of the dustproof fixing plate 8 is fastened to the fastening connection groove by the fixing rubber pad 82. Together with the waterproof sealing ring 7, it prevents dust and liquid from entering. When the baffle is opened, the reverse operation causes the locking block to disengage from the cross locking groove. All the structures work together to achieve protection, sealing and stable fixing of the optical module connection.

[0045] Compared with the prior art, the present invention has the following advantages:

[0046] 1. A movable baffle 3 that can be rotated and adjusted is provided at the connection entry end of the interface housing 1 of the optical module connection interface. The movable baffle 3 is used to seal the entry end of the interface housing 1, and by rotating the movable baffle 3, it can provide a certain degree of shielding and protection for the optical fiber link connected to the connection interface. At the same time, a dustproof fixing piece 8 and a waterproof sealing ring 7 that fit with the movable baffle 3 are provided on the inner side of the interface housing 1 to achieve overall sealing of the interface housing 1, preventing the connection interface from being directly exposed, effectively reducing dust adhesion, and improving the safety and stability of the connection interface.

[0047] 2. Flexible thin plates 4 that can be pulled and adjusted are provided at both ends of the movable baffle 3. The elasticity inside the thin plates 4 can clamp and fix the fiber optic link inserted into the connection interface to a certain extent, further enhancing the stability of the connection interface and reducing the impact of loose connection.
