技术领域technical field

本申请涉及光纤连接器的领域，尤其是涉及一种室内外两用防水光纤连接器。The present application relates to the field of optical fiber connectors, and in particular, to an indoor and outdoor waterproof optical fiber connector.

背景技术Background technique

目前，光纤已经成为互联网通信技术中重要的信号传输载体。光纤连接器是一种连接光纤与光纤之间的器件，可以在光纤的端面之间实现精密对接，将发射光纤输出的光能量能最大限度地耦合到接收光纤中。市面上的光线连接器种类繁多，其中，室内外两用防水光纤连接器可以应用于室外，且广泛应用于移动通信基站的数字传输中。At present, optical fiber has become an important signal transmission carrier in Internet communication technology. Optical fiber connector is a device that connects optical fibers and optical fibers, which can realize precise butt joint between the end faces of optical fibers, and couple the light energy output from the transmitting optical fiber to the receiving optical fiber to the maximum extent. There are many types of optical connectors on the market. Among them, indoor and outdoor dual-purpose waterproof optical fiber connectors can be used outdoors, and are widely used in digital transmission of mobile communication base stations.

相关技术中的光纤连接器一般包括有两个光传输的MT插芯，MT插芯的内部设置有光纤，且两MT插芯相对的端面设置有与光纤相对应的纤芯孔。MT插芯的外周壁套设有具有保护作用的套管，套管的外侧设置有金属外壳，两金属外壳可拆卸连接。当两个金属外壳组合时，两个MT插芯的传输端相互找平，位于两端面上的各个纤芯孔精密对接，从而实现光传输。The optical fiber connector in the related art generally includes two MT ferrules for optical transmission, the interior of the MT ferrule is provided with an optical fiber, and the opposite end faces of the two MT ferrules are provided with fiber core holes corresponding to the optical fibers. The outer peripheral wall of the MT ferrule is provided with a protective sleeve, the outer side of the sleeve is provided with a metal shell, and the two metal shells are detachably connected. When the two metal shells are combined, the transmission ends of the two MT ferrules are leveled with each other, and the core holes on both ends are precisely butted to realize optical transmission.

针对上述中的相关技术，发明人认为MT插芯的纤芯孔孔径较小，且随着MT插芯内的光线数量越多，纤芯孔的密度也越大，对MT插芯端面对接时的精准度要求也越大，但操作人员在组装金属外壳时会发生抖动，容易使两MT插芯的端面之间发生偏移，影响了光纤通道的接通质量。In view of the above-mentioned related technologies, the inventor believes that the diameter of the core hole of the MT ferrule is smaller, and as the number of rays in the MT ferrule increases, the density of the core hole is also greater, and when the end face of the MT ferrule is connected, the The accuracy requirements of the MT are also greater, but the operator will shake when assembling the metal casing, which is easy to cause the end faces of the two MT ferrules to shift, which affects the connection quality of the fiber channel.

通过采用上述技术方案，扁平部增大第二弹力件的形变范围，使第二弹力件相对于第一弹力件更易于发生弯折。扁平部从对应的方向折弯，从而吸收公芯及母芯的抖动，使公芯及母芯的运动趋向于沿第一弹力件轴向上的滑移，提高公芯及母芯的抗震性，同时增强连接稳定性。By adopting the above technical solution, the flat portion increases the deformation range of the second elastic member, so that the second elastic member is more likely to bend relative to the first elastic member. The flat part is bent from the corresponding direction, so as to absorb the jitter of the male core and the female core, so that the movement of the male core and the female core tends to slide along the axial direction of the first elastic member, so as to improve the shock resistance of the male core and the female core , while enhancing connection stability.

A connecting block is connected between the two, and a clearance gap is formed between the limiting block and the connecting block.

通过采用上述技术方案，当两限位块抵接于母芯尾端时，两定位杆插接于对应的第二定位槽。操作人员安在组装母芯时，可将束线工件插进让位间隙中，推动两限位块使定位杆插进对应的第二定位槽中，使限位块抵接于母芯。By adopting the above technical solution, when the two limiting blocks abut against the rear end of the female core, the two positioning rods are inserted into the corresponding second positioning grooves. When assembling the mother core, the operator can insert the wire harness workpiece into the clearance gap, push the two limit blocks to insert the positioning rods into the corresponding second positioning grooves, and make the limit blocks abut against the mother core.

通过采用上述技术方案，操作人员安装时导针时，可将导针夹紧于固定槽的槽壁内，使导针与固定箍卡接固定。完成此步骤后，操作人员将光纤线束放置进限位间隙内，并使两固定箍分别朝接近公芯的方向移动，随着导针逐渐插进第一定位槽中，第一限位套逐渐插进限位间隙中；待第一抵接面抵接于公芯时，两固定箍抵接于第一限位套的外侧，导针外露于公芯的传输端。在此过程中，限位间隙在固定箍远离连接片的一侧形成一个开口，方便操作人员将线束放置进限位间隙，提高组装效率。另一方面，固定箍与第一限位套之间的摩擦力使固定箍不易于脱离公芯，增强导针与公芯之间的稳定性。By adopting the above technical solution, when installing the guide needle, the operator can clamp the guide needle in the groove wall of the fixing groove, so that the guide needle and the fixing hoop can be clamped and fixed. After completing this step, the operator places the optical fiber harness into the limit gap, and moves the two fixing hoops toward the male core respectively. As the guide pin is gradually inserted into the first positioning groove, the first limit sleeve gradually Inserted into the limit gap; when the first abutting surface abuts on the male core, the two fixing hoops abut on the outside of the first limit sleeve, and the guide pin is exposed on the transmission end of the male core. In this process, the limit gap forms an opening on the side of the fixing hoop away from the connecting piece, which facilitates the operator to place the wire harness into the limit gap and improves the assembly efficiency. On the other hand, the frictional force between the fixing hoop and the first limiting sleeve makes it difficult for the fixing hoop to be separated from the male core, thereby enhancing the stability between the guide pin and the male core.
