Description

Technical Field

[0001] This utility model relates to the field of optical communication technology, specifically to a loss-preventing optical module connection structure. Background Technology

[0002] Optical modules are core components in optical communication systems, enabling photoelectric signal conversion. The accuracy of their connection to the optical interface directly affects the quality of optical signal transmission. Existing optical module connection structures generally suffer from the following defects: First, insufficient positioning accuracy during insertion and removal easily leads to component misalignment and optical signal coupling loss; second, poor interface sealing performance allows dust and moisture to easily penetrate and contaminate core components, reducing signal transmission efficiency; third, insufficient reliability of connection locking makes them prone to loosening under vibration and impact, causing signal interruption or attenuation; fourth, the lack of a buffer structure during insertion and removal allows hard contact to easily cause wear on precision components such as ceramic ferrules, shortening their lifespan; and fifth, the absence of anti-slip design during operation results in poor ease of insertion and removal. These problems seriously affect the transmission stability and lifespan of optical modules, making it difficult to meet the low-loss requirements of high-speed optical communication scenarios. Therefore, a loss-resistant optical module connection structure is proposed. Utility Model Content

[0003] In view of this, the present invention provides a loss-resistant optical module connection structure, which aims to solve one of the technical problems of transmission loss caused by inaccurate positioning, poor sealing, loose locking, easy wear and tear, and inconvenient operation of existing optical module connections.

[0004] The technical solution of this utility model is implemented as follows: a loss-proof optical module connection structure includes an optical module body, one end of which is connected to a connection component, and the other end of the connection component is inserted into the interior of an optical interface. The optical interface includes an interface shell, one side of which is provided with symmetrical guide grooves, and one end of the interface shell is provided with a sealing gasket. A second guide strip adapted to the guide groove is installed on one side of the sealing gasket.

[0005] A further preferred embodiment: the connecting assembly includes a plastic shell, a tail sleeve, a first guide strip, a groove, and a ceramic insert. The ceramic insert is embedded inside one end of the plastic shell, and the tail sleeve is connected to the other end of the plastic shell. The first guide strip is provided on the top surface of the plastic shell, and grooves are symmetrically provided on the inner walls of both sides of the plastic shell.

[0006] A further preferred embodiment: the outer wall of the plastic shell is provided with anti-slip textured sections.

[0007] A further preferred embodiment: the other end of the interface housing has symmetrically arranged docking channels inside, and each docking channel is connected to a locking protrusion that matches the groove.

[0008] A further preferred embodiment: the two side walls of the interface housing are symmetrically equipped with baffles, which can prevent hand contamination of the docking parts.

[0009] A further preferred embodiment: the interface housing has a ferrule mounting cavity installed inside.

[0010] A further preferred embodiment: elastic buffers are symmetrically installed on both sides of one end of the interface housing.

[0011] The present invention has the following advantages over the prior art: 1. This utility model ensures the coaxiality of the connection component and the optical interface through the dual guiding cooperation of the first guide bar and the guide groove, and the second guide bar and the guide groove, thereby reducing optical signal coupling loss and solving the problem of inaccurate positioning in traditional connections.

[0012] 2. The sealing gasket of this utility model is made of silicone material, which has good resilience and sealing performance, effectively blocking dust and moisture intrusion, avoiding contamination of the ceramic ferrule end face, and ensuring the light signal transmission efficiency.

[0013] 3. The groove and the protrusion of this utility model adopt an interference fit design, which automatically locks and engages during insertion and removal, resulting in high connection strength. It can resist the risk of loosening caused by vibration and collision, and ensure transmission stability.

[0014] 4. The elastic buffer of this utility model is made of rubber, which provides buffering force during insertion and removal, avoids hard contact between the ceramic core and the inside of the interface, reduces component wear, and extends service life.

[0015] 5. The anti-slip textured section of the plastic shell of this utility model increases the grip friction, making insertion and removal operations easier, and the baffle can prevent the hand from contacting the precision docking parts, thus improving the safety and convenience of operation.

A core mounting cavity 305 is installed inside the interface shell 301. Elastic buffers 306 are symmetrically installed on both sides of one end of the interface shell 301.

[0021] In this embodiment, specifically: the optical module body 1 adopts the existing standard optical module structure, and its output end is fixedly connected to the connection component 2 by welding to ensure connection stability.

[0022] In the connecting component 2, the plastic shell 201 is made of flame-retardant ABS plastic through one-piece injection molding, possessing the characteristics of insulation, lightness, and high strength; the anti-slip textured section 202 is an annular texture integrally formed on the outer wall of the plastic shell 201, with a texture depth of 0.8-1.2mm, increasing grip friction; the tail sleeve 203 is made of elastic rubber material and is fixed to the rear end of the plastic shell 201 by a snap-fit ​​connection, used to protect the connection between the optical fiber and the ceramic ferrule 206 and reduce bending stress; the first guide strip 204 is an elongated protrusion integrally formed on the top of the plastic shell 201, with a trapezoidal cross-section, and is clearance-fitted with the guide groove 304, with the gap controlled at 0.1-0.2mm; the groove 205 is a symmetrically opened C-shaped groove on both sides of the plastic shell 201; the ceramic ferrule 206 is made of zirconia ceramic material and is embedded into the front end of the plastic shell 201 through an interference fit, with its central aperture matching the optical fiber to ensure accurate transmission of optical signals.

[0023] In the optical interface 3, the interface housing 301 is die-cast from aluminum alloy, which combines heat dissipation and structural strength; the docking channel 302 is a rectangular channel symmetrically opened inside the rear opening of the interface housing 301, which fits the two sides of the plastic housing 201; the latching protrusion 303 is a V-shaped protrusion integrally formed inside the docking channel 302, with a protrusion angle of 61-62°, which is interference-fitted with the groove 205 to achieve locking and fixation; the guide groove 304 is a trapezoidal groove symmetrically opened on one side of the interface housing 301, which fits the first guide strip 204 and the second guide strip 308 respectively; the ferrule mounting cavity 305 is a cylindrical cavity opened inside the interface housing 301.
