Description

Fiber Optic Connectors and Fiber Optic Connector Assemblies

technical field

The present disclosure generally relates to cable connectors. More particularly, the present disclosure relates to a fiber optic connector suitable for outdoor use and a fiber optic connector assembly including the same.

Background technique

Fiber optic cables are increasingly being used to transmit information. Large amounts of information are converted into optical signals and then transmitted via fiber optic cables. Fiber optic cables typically include one or more fibers, aramid surrounding the fibers and/or filled between the fibers, and a jacket surrounding the fibers and the aramid.

Fiber optic connectors are provided for connecting fiber optic cables. Fiber optic cables are coupled within fiber optic connectors such that the fibers in different fiber optic cables are aligned with each other to transmit optical signals therebetween.

Most of the existing fiber optic connectors cannot be used outdoors. When used outdoors, the existing optical fiber connectors are easily affected by outdoor environmental factors (such as water, moisture, smoke, dust, etc.), thereby seriously impairing the transmission performance of the optical fiber. For example, neither standard SC-type fiber optic connectors nor LC-type fiber optic connectors provide adequate protection against fluid intrusion or other outdoor environmental factors, making them only available indoors.

Currently, there is an increasingly urgent need for fiber optic connectors that can be used outdoors. In particular, fiber optic connectors that can be used outdoors are critical to fiber-to-the-antenna (FTTA) interconnect network solutions.

1-3, a first connector 100 is shown. The first connector 100 may be configured as a straight fiber optic cable connector (in the present disclosure, a male fiber optic connector) for connecting the cable 101 . Cable 101 may be one of many commonly used fiber optic cables, including fiber optic distribution cables or hybrid fiber optic cables. According to embodiments of the present disclosure, the cable 101 may include one or more optical fibers 102 , aramid surrounding and/or filled between the optical fibers 102 , and a jacket surrounding the optical fibers 102 and the aramid. In FIGS. 1 to 3 , the aramid and the sheath are schematically shown together and designated by reference numeral 103 .

The first connector 100 may include: a connector body 110; a fiber optic connection assembly 120 disposed within the connector body 110 and proximate the proximal end of the connector body 110; a locking assembly 130 for retaining the cable 101, the locking assembly disposed near the distal end of the fiber optic connector assembly; and a sealing element 140 at the distal end of the fiber optic connector body 100 configured to seal the connection between the distal end of the fiber optic connector 100 and the outer circumference of the cable 101 .

The proximal end of the elongated member 121 may include a ceramic ferrule, while the distal end of the elongated member 121 may be provided with a cavity for receiving, for example, an optical fiber, for connection to the optical fiber. According to some embodiments of the present disclosure, the elongated member may be an LC-type optical fiber connection element comprising a ceramic ferrule having a diameter substantially equal to 1.25 mm. In other embodiments, the elongated member may be an SC-type fiber optic connection element comprising a ceramic ferrule having a diameter substantially equal to 2.5 mm.

In the embodiment shown in FIG. 1, the fiber optic connection assembly 120 includes two elongate members 121, each of which is shown as an LC-type fiber optic connection element. Of course, as discussed above, each elongated member 121 may also be configured as an SC-type fiber optic connection element, or any other suitable type of fiber optic connection element. Additionally, although not shown, the fiber optic connection assembly 120 may also include three or more elongated members 121 . Where the fiber optic connection assembly 120 includes a plurality of elongated members 121, the use of LC-type fiber optic connection elements can reduce the size of the fiber optic connection assembly 120.

Next, the locking assembly 130, which is configured to secure the cable 101, is described. When the cable 101 is connected to the first connector 100, the locking assembly 130 can prevent the optical fiber 102 of the cable 101 from being disconnected from the elongated member 121 from being pulled by an external force, and the locking assembly 130 also The optical fiber 102 of the cable 101 can be prevented from being damaged due to jittering or wobbling of the cable 101 .

According to an embodiment of the present disclosure, the locking assembly 130 includes a first locking mechanism for crimping at least the sheath of the cable 101 (preferably aramid and the sheath 103 ) and a second locking mechanism for gripping the cable 101 itself A locking mechanism, the first locking mechanism can at least prevent the sheath (preferably, the aramid and the sheath 103) from being detached from the optical fiber under the action of an external force, and the second locking mechanism can prevent the cable from being under the action of an external force can be pulled down, causing the optical fiber to disconnect from the elongated member 121 or damage the optical fiber due to jittering or wobbling of the cable 101 .

The first locking mechanism includes a support member 131 and a crimping member 132 . The outer surface of the support member 131 is used to engage at least the sheath of the cable 101 or the aramid and the sheath 103 of the cable 101, and the crimping member 132 is used to cooperate with the support member 131 to attach the sheath or the aramid and the sheath. 103 is crimped between the support member 131 and the crimping member 132 . Specifically, in the embodiment shown in FIGS. 1 to 3 , the support member 131 includes a first cylindrical portion 1311 with a larger diameter and a second cylindrical portion 1312 with a smaller diameter. The optical fiber 102 extends through the first cylindrical portion 1311 and the second cylindrical portion 1312 , and the jacket or aramid and the jacket 103 engage the outside surface of the second cylindrical portion 1312 . The crimping part 132 may be configured as a crimping sleeve, which can be sleeved on the outer side surface of the second cylindrical portion 1312 of the supporting part 131 and can be reduced in diameter by crimping, so that the sheath or aramid can be reduced in diameter by crimping. And the sheath 103 is clamped between the support member 131 and the crimping member 132 .

The second locking mechanism includes a clamping member 133 and a tightening member 134 for tightening the clamping member 133 . The cable 101 can extend through the clamping member 133 and the constricting member 134 . The gripping member 133 includes a gripping portion 1332 formed by a plurality of elastic fingers 1331 (see FIGS. 2 and 3 ). The plurality of elastic fingers 1331 are arranged to be spaced apart from each other in the circumferential direction. The gripping portion 1332 formed by the plurality of elastic fingers 1331 may have a tapered shape, the diameter of which gradually decreases from the proximal end toward the distal end. Accordingly, the proximal end of the compression member 134 is provided with a lumen 1341 for receiving the gripping portion 1332 of the gripping member 133 (see FIG. 3 ). The lumen 1341 has a tapered conical shape with a diameter that gradually decreases from the proximal end toward the distal end. In this way, when the clamping portion 1332 of the clamping member 133 is inserted into the inner cavity 1341 of the tightening member 134, since the diameter of the inner cavity 1341 is gradually reduced, the plurality of elastic fingers 1331 are subjected to radially inward pressure. The compressive force deforms radially inwards and thus gradually gathers, thereby being able to clamp the cable 101 extending therethrough.

The inner surface of the elastic fingers 1331 may be provided with protrusions 1333 . The protrusions 1333 help the resilient fingers 1331 to grip the cable 101 more securely.

Specifically, the distal portion of the connector body 110 is provided with internal threads, and the proximal portion of the compression member 134 is provided with external threads, so that the compression member 134 can be screwed into the distal portion of the connector body 110 . During the threading process of the tightening part 134 and the connector body 110 , the clamping part 1332 of the clamping part 133 gradually penetrates into the conical cavity 1341 of the clamping part 134 , so that the elastic finger-like shape of the clamping part 1332 The piece 1331 gradually deforms radially inward to clamp the cable 101 .

In addition, in order to achieve sealing of the connection interface between the compression member 134 and the connector body 110 , a sealing member 1342 may be provided on the outer periphery of the compression member 134 . The seal 1342 may be received in an annular groove provided on the outer periphery of the compression member 134 . When the compression member 134 is threaded onto the connector body 110, the seal 1342 is compressed between the compression member 134 and the connector body 110, thereby achieving a seal at the connection interface. According to embodiments of the present disclosure, the seal 1342 may be configured in the form of an O-ring. However, the present disclosure is not so limited, and other forms of seals may be used, such as seals having a rectangular cross-section.

As mentioned above, a sealing element 140 is also provided at the distal end of the first connector 100 . The sealing element 140 is configured to form a seal at the distal end of the first connector 100 and the outer circumference of the cable 101 to prevent water, moisture, dust, etc. from the distal end of the fiber optic connector 100 or along the outer peripheral surface of the cable 101 And enter the inside of the first connector 100 . According to an embodiment of the present disclosure, the sealing element 140 includes a cylindrical body 1401 and a flange 1402 disposed at a proximal end of the cylindrical body 1401 . The cylindrical body 1401 can be tightly fitted on the outer periphery of the cable 101, and the length of the cylindrical body 1401 is designed to be sufficient to ensure that water, moisture, dust, etc. do not enter the first connector along the outer peripheral surface of the cable 101 100 inside. The flange 1402 is configured to seal the distal end of the first connector 100 . According to an embodiment of the present disclosure, the distal end portion of the constriction member 134 is provided with a second cavity for receiving the flange 1402 of the sealing element 140 . The flange 1402 of the sealing element 140 extends into the second cavity of the compression member 134, and the end face and outer surface of the flange 1402 abut the end face 1343 and the inner surface 1344 of the second cavity of the compression member 134, respectively, thereby A seal is formed at both the end face 1343 and the inner face 1344 of the second cavity.

The flange 1402 of the sealing element 140 may be clamped between the constriction member 134 and the end plug 141 by means of the end plug 141 . As shown more clearly in FIGS. 1 and 3 , the end plug 141 may also extend into the second cavity of the compression member 134 and be threaded with the compression member 134 . Depending on how far the end plug 141 extends into the second cavity of the compression member 134, the flange 1402 of the sealing element 140 may be compressed to different degrees in order to achieve the desired sealing effect. A gasket 142 may also be provided between the flange 1402 of the sealing element 140 and the end plug 141 . On the one hand, the gasket 142 can protect the sealing element 140; on the other hand, by selecting the thickness of the gasket 142, the degree to which the end plug 141 compresses the flange 1402 of the sealing element 140 can be adjusted.

The sealing element 140 may be made of silicone rubber. The sealing element 140 can be shaped differently according to actual needs.

In embodiments where the fiber optic connection assembly 120 includes a plurality of elongated members 121, each elongated member 121 may be coupled to an optical fiber 102, respectively. In order to effectively separate the individual fibers 102 , a separation element 125 may be provided between the fiber optic connection assembly 120 and the locking assembly 130 . The separation element 125 may be configured in the shape of a cylinder, and a through hole for the passage of the optical fiber 102 is provided therein (see FIGS. 1 and 3 ). Separating the optical fibers 102 by extending the different optical fibers 102 through different through holes, respectively, facilitates the coupling of the optical fibers 102 to the elongated member 121 .

The basic structure of the first connector 100 according to the embodiment of the present disclosure is described above. By disposing the optical fiber connection assembly 120 inside the connector body 110 and sealing the interface between the distal end of the first connector 100 and the outer surface of the cable 101 by means of the sealing member 140, water, moisture can be effectively prevented , dust, etc. enter the inside of the first connector 100 , so that the first connector 100 can be used outdoors.

In the first connector 100, rotation of the various parts within the connector body 110 is undesirable. Since the optical fiber 102 is fragile, rotation of the parts within the connector body 110 can cause rotation of the cable 101, which can result in damage to the optical fiber 102. In order to prevent each part from rotating within the connector body 110, the outer periphery of each part is configured in a polygonal structure. Correspondingly, the inner surface of the connector body 110 is also configured to have a polygonal structure matched with each part. In this way, when the respective parts are assembled in the connector body 110 , the rotation of the respective parts relative to the connector body 110 can be effectively prevented. For example, in the embodiment shown in FIG. 2 , at least a part of the outer circumference of the support member 131 is configured in a hexagonal structure. Likewise, at least a part of the outer circumference of the holding member 133 is also configured in a hexagonal structure. Of course, the present disclosure is not limited thereto, and the outer periphery of each part may be configured into other polygonal structures, such as quadrilaterals, pentagons, and the like.

Continuing to refer to FIG. 2 , for ease of assembly, corresponding alignment features may also be provided on various parts of the first connector 100 .
