Detailed Description

In order to make the objects, technical solutions and advantages of the present application more apparent, the present application is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present application and are not intended to limit the present application.

It should be noted that the terms first, second and the like in the description and in the claims, and in the drawings described above, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order.

At present, the most common connection mode of the optical cable connector is generally realized by an adapter, a pigtail and a field-assembled optical cable quick assembly, however, because the optical cable connector has poor waterproof performance and is generally placed inside optical communication equipment, when construction needs to be performed, the optical communication equipment needs to be opened, and then the optical cable connector needs to be butted. However, the optical fiber inside the optical communication device is poor, and when the optical fiber connector is butted, the assembled optical cable is easily affected, so that the communication signal of the opened customer is affected, meanwhile, the optical fiber connector needs a plurality of components for connection, and a single person cannot operate quickly, so that other operators are needed for assisting in butting.

The embodiments of the present application will be further explained with reference to the drawings.

FIG. 1 is a perspective view of a fiber optic cable assembly provided by one embodiment of the present application.

As shown in fig. 1, the optical cable assembly includes: a first optical cable connector 100, a second optical cable connector 200; the first cable connector 100 includes a first locking assembly 110 and the second cable connector 200 includes a second locking assembly 210.

As shown in fig. 2, the first locking assembly 110 includes a plug-in slot 111 and a locking slot 112, the plug-in slot 111 is connected with the locking slot 112 through a connecting portion 113, and the second locking assembly 210 includes a plug 211; the plug 211 is configured to be inserted into the first locking member 110 through the insertion groove 111 and into the locking groove 111 via the connection portion 113.

When the plug 211 is inserted into the plug groove 111, the plug groove 111 guides the plug 211 to be inserted into the first locking unit 110, the plug 211 is inserted into the locking groove 112 through the connection portion 113, and the plug 211 is automatically locked in the locking groove 112 by the second locking unit 210. The plug 211 is inserted into the locking groove 112 by the guiding action of the inserting groove 111 and the connecting portion 113, so that the plug 211 is automatically inserted into the locking groove 112 and then is stably locked in the locking groove 112 by the second locking assembly 210, thereby simplifying the inserting process of the first optical cable connector 100 and the second optical cable connector 200 and realizing automatic locking.

In one embodiment, the insertion slot 111 further includes a guide 114, and the insertion piece 211 is configured to be inserted into the first locking assembly 110 along the guide 114.

When the plug 211 is inserted into the insertion groove 111, the plug 211 is gradually inserted into the insertion groove 111 under the guiding action of the guide portion 114 until the plug 211 is inserted into the connection portion 113. Since a force is generated by the interaction of the second locking assembly 210 and the guide portion 114, the insertion and locking of the connector 211 into the locking slot 112 can be driven, thereby completing the automatic locking of the connector 211.

Referring to fig. 2 and 3, in one embodiment, the second locking assembly 210 further includes at least: a plug inner housing 212, a plug outer housing 213, and a locking mechanism 214; the plug inner housing 212 is disposed on the second optical cable connector 200; the plug outer sleeve 213 is sleeved on the plug inner sleeve 212; the plug connector 211 is arranged on the outer surface of the plug outer sleeve 213, and the plug connector 211 is inserted along the opening of the locking groove 112 and locked in the locking groove 112; the locking mechanism 214 is disposed between the plug inner housing 212 and the plug outer housing 213, and the locking mechanism 214 is used to automatically lock the plug 211 inside the locking slot 112. For example, locking mechanism 214 may be any component that generates a restoring force that is provided to insert 211 to actuate insert 211 to lock within locking slot 112.

Referring to fig. 1, 2 and 3, when the plug housing 213 is plugged with the first optical cable connector 100, after the plug 211 is inserted into the plugging slot 111, the second optical cable connector 200 is pushed to connect with the first optical cable connector 100, so that the plug 211 on the plug housing 213 is inserted along the plugging slot 111. Since the guiding portion 114 of the slot 111 guides the insertion of the plug 211 and provides a force to the plug 211, the plug 211 is forced to rotate the plug outer sleeve 213 relative to the plug inner sleeve 212 in a first direction. The locking mechanism 214 generates a force that causes the plug outer housing 213 to rotate relative to the plug inner housing 212 in a second direction when the plug outer housing 213 rotates. The second direction is opposite to the first direction. The guide portion 114 may be an inclined surface. When the plug housing 213 is inserted, the plug 211 is continuously rotated in the first direction during the insertion process since the plug 211 is guided by the guide 114. Until the plug 211 leaves the guide 114, the plug 211 is automatically locked by the force of the locking mechanism 214.

In one embodiment, if the plug outer sleeve 213 is rotated clockwise along the plug inner sleeve 212 by the guide portion 114 when the plug 211 is inserted into the insertion slot 111, the locking mechanism 214 generates a force during the clockwise rotation, which has the effect of urging the plug outer sleeve 213 to rotate counterclockwise along the plug inner sleeve 212. As the plug 211 and the socket 111 are further inserted, the plug outer sleeve 213 is continuously rotated clockwise with respect to the plug inner sleeve 212 under the guidance of the guide portion 114, and the acting force generated by the locking mechanism 214 is gradually increased. The plug connector 211 arranged on the outer surface of the plug outer sleeve 213 further rotates clockwise relative to the plug inner sleeve 212 in the process until the plug connector 211 is separated from the guide part 114, and the plug connector 211 which is guided by the guide part 114 is lost rotates anticlockwise under the action of the locking mechanism 214, so that automatic locking is realized. Therefore, the plug housing 213 is locked to the first optical cable connector 100, the second optical cable connector 200 is easily and easily plugged into the first optical cable connector 100 in a labor-saving manner, and the plug housing can be automatically locked.

Referring to fig. 3 and 4, in one embodiment, the locking mechanism 214 includes: the plug comprises an elastic piece 215 and a limiting surface 216, wherein a placing groove 217 is arranged on the plug inner sleeve 212, and one end of the placing groove 217 can be of an opening structure; further, the placement groove 217 may be provided on the side of the plug inner housing 212 adjacent to the plug outer housing 213. The elastic member 215 is at least partially disposed in the placement groove 217, and the stopper surface 216 is disposed on the inner wall of the plug housing 213. The stopper surface 216 cooperates with the placement groove 217 to press the elastic member 215 in the placement groove. When the plug outer housing 213 rotates to a certain angle in the plug inner housing 212, the stopper surface 216 presses the elastic member 215 in the placement groove 217, so that the elastic member 215 deforms.

Referring to fig. 2, 3 and 4, when the plug 211 is inserted into the plug groove 111, the plug 211 is inserted into the plug groove 111 along the guide portion 114, the guide portion 114 provides a force to the plug 211, and the plug outer sleeve 213 rotates in a first direction relative to the plug inner sleeve 212 when the plug 211 is applied with the force. The stop surface 216 on the inside of the plug housing 213 is driven to approach the resilient member 215 when the plug housing 213 is rotated in the first direction. As the plug housing 213 continues to rotate, the position-limiting surface 216 and the positioning groove 217 cooperate with each other to press the elastic member 215, the deformed elastic member 215 generates a restoring force to the position-limiting surface 216, and the position-limiting surface 216 drives the plug housing 213 to rotate along the second direction under the action of the restoring force. The first direction is opposite to the second direction. The guide portion and the plug 211 are engaged with each other to guide the plug outer 213 to rotate in the first direction with respect to the plug inner 212, and as the plug 211 is gradually inserted into the insertion groove 111, the stopper surface 216 and the placement groove 217 in the plug outer 213 are engaged to press the elastic member 215, so that the elastic member 215 generates a restoring force to the stopper surface 216. When the plug 211 is separated from the guide 114, the plug 211 is automatically dropped into the locking groove 112 by the restoring force of the elastic member 215 to drive the plug 211 to drop into the locking groove 112, and the plug 211 drops into the locking groove 112.

In an embodiment, after the plug 211 is inserted into the plug slot 111, the plug 211 rotates the plug outer sleeve 213 clockwise along the plug inner sleeve 212 under the action of the guide portion 114, the limiting surface 216 is driven to gradually press the elastic member 215 during the clockwise rotation of the plug outer sleeve 213, and the deformed elastic member 215 generates a restoring force to the limiting surface 216. The plug 211 and the plug groove reach the connection portion 113 after being inserted, at this time, the limit surface 216 drives the plug outer sleeve 213 to rotate counterclockwise along the plug inner sleeve 212 under the action of the restoring force, and the plug 211 on the plug outer sleeve 213 also automatically rotates to fall into the locking groove 112, so that the elastic member 215 is restored to the original state. Therefore, the plug housing 213 and the first optical cable connector 100 can be plugged and automatically locked, and the plug 211 can be automatically locked in the locking groove 112, so that the second optical cable connector 200 (shown in fig. 1) and the first optical cable connector 100 (shown in fig. 1) can be plugged easily and automatically locked.

In one embodiment, the plurality of positioning slots 217 may be provided, and the positioning slots 217 are provided in the same number as the number of the elastic members 215, and the plurality of elastic members 215 can increase the restoring force of the plug-in connector 211, so that the plug-in connector 211 is more stably locked in the locking slot 112.

In this embodiment, two elastic members 215 are provided, and by providing two elastic members 215, on one hand, the force applied to the plug-in connector 211 on the plug housing 213 is equalized, and on the other hand, the other elastic member 215 can continue to operate after one of the elastic members 215 is damaged, so as to keep the automatic locking function of the locking mechanism 214 normal.

In this embodiment, the elastic member 215 is a coil spring, and in other embodiments, the elastic member 215 may be a leaf spring, a planar volute spring, a pressure spring tube, a bellows, a diaphragm, etc., so that an operator can select different types of elastic members 215 according to the performance requirements of the elastic member 215.

Referring to fig. 1 and 5, in one embodiment, the plug housing 213 includes: the locking outer sleeve 218 is sleeved at one end of the plug inner sleeve 212 far away from the second optical cable connector 200, the detaching outer sleeve 219 is sleeved at one end of the plug inner sleeve 212 near the second optical cable connector 200, and the detaching outer sleeve 219 abuts against the locking outer sleeve 218. The detaching outer sleeve 219 is detachably connected to the second optical cable connector 200, and the locking outer sleeve 218 is sleeved on the plug inner sleeve 212 and is limited by the end of the plug inner sleeve 212 to slide out.

The locking outer sleeve 218 is limited on the plug inner sleeve 212 by the plug inner sleeve 212 and cannot be detached, the detaching outer sleeve 219 is abutted with the locking outer sleeve 218 by detachably connecting the detaching outer sleeve 219 with the second optical cable connector 200, so that after the detaching outer sleeve 219 is detached from the second optical cable connector 200, the detaching outer sleeve 219 can be taken out from one end of the plug inner sleeve 212 close to the second optical cable connector 200, and the locking outer sleeve 218 can also be taken out from the plug inner sleeve 212, so that the elastic member 215 on the plug inner sleeve 212 can be maintained or replaced, the normal use of the elastic member 215 is ensured, and the plug connector 211 on the plug outer sleeve 213 can be stably locked in the locking groove 112.

Referring to fig. 1, 4 and 5, in an embodiment, when the elastic member 215 in the placement groove 217 needs to be inspected, repaired or replaced, the detaching outer sleeve 219 and the second optical cable connector 200 are detached first, then the detaching outer sleeve 219 and the locking outer sleeve 218 are detached, and the detaching outer sleeve 219 is taken out along the plug inner sleeve 212 near one end of the second optical cable connector 200. After the release outer sleeve 219 is removed, the locking outer sleeve 218 is also removed along the end of the plug inner sleeve 212 adjacent to the second fiber optic connector 200. After the locking outer sleeve 218 is removed, the structure of the inner surface of the plug inner sleeve 212 can be clearly checked, and the elastic member 215 on the plug inner sleeve 212 can be adjusted, repaired and replaced.

Referring to fig. 5 and 6, in one embodiment, the plug 211 is disposed at an end of the locking housing 218 away from the detaching housing 219, and the limiting surface 216 is disposed inside the locking housing 218 and matches with the placement groove 217 (shown in fig. 3). The plug 211 may be a rib protruding on the outer circumferential side of the locking housing 218, and the shape of the plug 211 may be cylindrical, square, trapezoidal, etc., and the shape of the plug 211 is cylindrical in this embodiment.

Referring to fig. 1 and 6, the plug 211 is disposed on the locking housing 218, and when the locking housing 218 is plugged with the first optical cable connector 100, the plug 211 on the locking housing 218 can be quickly inserted into the plug slot to realize quick plugging of the second optical cable connector 200 and the first optical cable connector 100. The shape of the plug 211 can be adjusted according to actual requirements to ensure that the plug 211 is firmly locked in the locking groove 112 (see fig. 2). The shape of the plug 211 is cylindrical in this embodiment so that the cylindrical plug 211 better matches the guide.

Referring to fig. 1 and 7, in one embodiment, the first optical cable connector 100 further includes: a first optical cable connector body 120 and an adapter body 130, wherein the adapter body 130 is fixedly mounted on the first optical cable connector body 120, and the insertion groove 111 and the locking groove 112 are disposed on the adapter body 130.

After the first optical cable connector body 120 and the adapter body 130 are fixedly connected, the two optical cable connectors can be plugged only by connecting the adapter body 130 on the first optical cable connector body 120 with the second locking component 210 without the assistance of additional components, and an operator only needs to align and plug the two optical cable connectors, so that the optical cable connectors at two ends are connected more conveniently and quickly, and plug and play in air docking of the optical cable connectors is realized.

Referring to fig. 7, in an embodiment, the adapter body 130 is detachably connected to the first optical cable connector body 120, and the optical cable connector can be connected to the optical cable connector at the other end only by installing the adapter body 130 through the detachable connection structure, so that the adaptability of different types of optical cable connectors is improved.

Referring to fig. 1 and 7, in an embodiment, the adapter body 130 is detachably connected to the first optical cable connector 100, and when the optical cable connectors at both ends need to be plugged and locked, the adapter body 130 is fixedly mounted on the first optical cable connector 100. The adapter body 130 is aligned with the second locking assembly 210 of the second optical cable connector 200, and the plug 211 is locked in the locking groove 112 (see fig. 2) by the first locking assembly 110 and the second locking assembly 210 of the adapter body 130 being matched, thereby completing the plugging and locking of the second optical cable connector 200 and the first optical cable connector 100. When the adapter body 130 is damaged, the adapter body 130 can be detached from the first optical cable connector 100 to facilitate repair and replacement of the adapter body 130.

Referring to fig. 6 and 7, in an embodiment, the first locking assembly 110 may be provided in plurality, and correspondingly, the plug 211 is provided in plurality, and the number of the plug 211 is equal to that of the first locking assembly 110.

In this embodiment, two plug connectors 211 and two locking slots 112 are provided, and the two plug connectors 211 are respectively inserted into the two locking slots 112, so that the locking effect is better.

Referring to fig. 5 and 8, in an embodiment, the insertion groove 111 is obliquely opened on the adapter body 130, and the locking groove 112 is communicated with the insertion groove 111 and is located at a side end of the insertion groove 111. The first end of the insertion groove 111 is an open structure, the second end of the insertion groove 111 is communicated with the first end of the locking groove 112, and the plug connector 211 is locked at the second end of the locking groove 112.

Referring to fig. 2, 3 and 6, when the locking housing 218 and the adaptor body 130 are mated, the plug 211 is inserted from the first end of the insertion groove 111 and abuts against the guide portion 114. Since the insertion groove 111 is obliquely arranged, the guide portion 114 generates a force to the insertion piece 211 as the insertion piece 211 is gradually inserted along the insertion groove 111. The plug 211 is acted by a force to drive the locking outer sleeve 218 to rotate along the plug inner sleeve 212 along the first direction, and the locking outer sleeve 218 rotates along the plug inner sleeve 212 and simultaneously drives the limiting surface 216 to extrude the elastic member 215, so that the elastic member 215 is deformed to generate a restoring force to the limiting surface 216. When the plug 211 is inserted into the second end of the inserting slot 111, the locking outer housing 218 is rotated in the second direction relative to the plug inner housing 212 by the restoring force generated by the deformation of the elastic member 215. When the locking housing 218 is rotated in the second direction, the plug 211 falls into the locking groove 112 from the second end of the insertion groove 111, so that the elastic member 215 is restored to the original position, and the plug 211 is locked in the locking groove 112. The locking outer sleeve 218 and the adapter body 130 are automatically locked, and the operation is simple.

When plug connector 211 inserts along inserting groove 111, along with locking overcoat 218 and adapter body 130 are pegged graft, then plug connector 211 drives locking overcoat 218 and rotates along the clockwise under the effect of guide part 114, along with locking overcoat 218 clockwise turning, spacing face 216 mutually supports with extrusion elastic component 215 with standing groove 217, elastic component 215 takes place deformation and produces an effort to spacing face 216, and this effort can make locking overcoat 218 along plug endotheca 212 anticlockwise turning. When the plug connector 211 is inserted into the second end of the inserting slot 111, since the second end of the inserting slot 111 is communicated with the locking slot 112, the restoring force generated by the elastic element 215 drives the locking housing 218 to rotate counterclockwise, that is, the plug connector 211 on the locking housing 218 slides into along the locking slot 112 until the plug connector 211 is inserted into the slot bottom of the locking slot 112, and the elastic element 215 returns to the initial state, thereby completing the locking of the plug connector 211. When the plug 211 is required to leave the locking groove 112, the locking outer sleeve 218 is required to rotate clockwise relative to the plug inner sleeve 212, so that the plug 211 can be stably locked in the locking groove 112 without external force, thereby realizing automatic locking of the locking outer sleeve 218 and the plug 211.

In one embodiment, the connecting portion 113 is a chamfer disposed between the insertion slot 111 and the locking slot 112, i.e., the second end of the insertion slot 111 and the first end of the locking slot 112 are chamfered, so that the insertion of the plug 211 into the locking slot 112 is easier when the plug 211 reaches the connecting portion 113 after being inserted into the insertion slot 111 to guide the insertion of the plug 211 into the locking slot 112.

In this embodiment, the locking groove 112 is opened on the adaptor body 130 and communicates with the outer surface of the adaptor body 130, and in other embodiments, the locking groove 112 is opened on the inner wall of the adaptor body 130 and does not communicate with the inner wall.

Referring to fig. 2, 3 and 8, in one embodiment, a guide assembly 300 is disposed between the adapter body 130 and the plug inner housing 212, the guide assembly 300 being configured to guide the plug inner housing 212 into alignment with the adapter body 130.

When the guide assembly 300 guides the plug inner 212 to align with the adapter body 130, the plug 211 on the locking outer 218 is inserted into the locking slot 112 on the adapter body 130, and the plug 211 abuts against the slot wall of the plug slot 111, so that the plug 211 can be locked in the locking slot 112 quickly.

In one embodiment, the guide assembly 300 includes: the adapter comprises a positioning column 310, a guide groove 320 and a positioning rib 330, wherein the positioning column 310 is fixedly installed in the adapter body 130 and inserted into the plug inner sleeve 212, the guide groove 320 is formed in the outer surface of the positioning column 310, and the positioning rib 330 is arranged on the inner wall of the plug inner sleeve 212 and inserted into the guide groove 320.

When the adapter body 130 and the locking outer sleeve 218 are plugged, the positioning column 310 is inserted into the plug inner sleeve 212, the positioning rib 330 is inserted into the opening of the guide groove 320, the plug connector 211 on the locking outer sleeve 218 abuts against the groove wall of the plug groove 111 through the mutual matching of the positioning rib 330 and the guide groove 320, and the positioning of the plug connector 211 and the plug groove 111 can be realized through the mutual matching of the positioning rib 330 and the guide groove 320, so that the plug connector 211 is quickly inserted into the plug groove 111 and then locked in the locking groove 112.

For example, when the locking housing 218 and the adapter body 130 are plugged, the positioning rib 330 is inserted along the opening of the guiding slot 320, the plug 211 on the locking housing 218 is inserted into the plugging slot 111 through the guiding action of the guiding slot 320 and the positioning rib 330, and the plug 211 abuts against the slot wall of the plugging slot 111 close to the locking slot 112. While the plug 211 is inserted along the insertion groove 111, the positioning rib 330 continues to be inserted along the guide groove 320 to maintain the positioning column 310 and the plug inner housing 212 to be sleeved. Until the plug 211 is locked after being inserted into the locking groove 112, the positioning rib 330 abuts against the groove bottom of the guide groove 320, thereby completing the insertion of the locking housing 218 and the adapter body 130.
