All other embodiments, which can be derived by a person skilled in the art from the described embodiments of the invention, belong to the scope of protection of the invention.
In the description of the present invention, it is to be understood that the terms "upper", "lower", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientation or positional relationship shown in fig. 2. The front and the back are based on the connection direction of the ferrule assembly, wherein the front refers to the direction of the ferrule near the connection position, and the back refers to the fiber outgoing direction far from the ferrule.
Communication transmission media includes, but is not limited to, optical transmission media (e.g., optical fibers) and electrical transmission media (e.g., wires). For convenience of description, in the embodiment of the present invention, the communication transmission medium 12 is an optical fiber, and the connector is an optical fiber connector.
The embodiment of the invention provides a connector, which comprises a first connecting sleeve 100 and an elastic device 300, wherein the first connecting sleeve 100 is sleeved outside a communication transmission medium 12; one end of the elastic device 300 abuts against the first connecting sleeve 100, the other end abuts against the ferrule 11 located at one end of the communication transmission medium 12, and after the first connecting sleeve 100 is fixed, the elastic device 300 can provide a pre-tightening force to the ferrule 11 along the axis (also referred to as an axis O indicated by a dotted line in fig. 6); the elastic device 300 is a hollow structure with two open ends, the elastic device 300 includes a first notch 310 through which the communication transmission medium 12 passes to enter the elastic device 300, and the first notch 310 intersects with the openings at the two ends of the elastic device 300; the first connection sleeve 100 is a hollow structure with two open ends, the first connection sleeve 100 includes a second notch 110 for the communication transmission medium 12 to pass through to enter the first connection sleeve 100, and the second notch 110 intersects with the openings at the two ends of the first connection sleeve (100).
In order to avoid the space occupied by the connector from being too large and to better stabilize the ferrule assembly 10, the two ends of the elastic device 300 are usually not sleeved outside the optical fiber from the ferrule 12 side, and similarly, the first connecting sleeve 100 is not sleeved outside the optical fiber from the ferrule 12 side. As shown in fig. 3, 5 and 6, the first notch 310 is penetrated from the side of the elastic means 300, and the second notch 110 is penetrated through the side wall of the first coupling sleeve 100. When the optical fiber is in the connection state shown in fig. 1, that is, when the bare ferrule assembly is out of the optical fiber, the optical fiber can enter the elastic device 300 through the first notch 310 and enter the first connecting sleeve 100 through the second notch 110, the ferrule 11 does not need to be omitted in this after-loading mode, the assembly of the connector can be completed under the condition that the original connection relationship of the optical fiber is not changed, the waste of materials is avoided, the assembly efficiency of the connector is improved, and the construction period is shortened.
The elastic means 300 may be a spring, a leaf spring, a part or a mechanism capable of providing elasticity. In the illustrated embodiment of the invention, the resilient means 300 is a spring, the projection of the resilient means 300 along its axis O being substantially C-shaped.
It will be appreciated that the first connector housing 100 may be secured to an adapter (not shown) or to a second connector housing 200 as described below depending on the configuration of the connector in use.
When the Connector according to the embodiment of the present invention is an SC type Connector (i.e., Square Connector), an LC type Connector (small rectangular optical fiber Connector), or an ST type Connector (light Tip Connector, such as a bayonet-type circular optical fiber Connector), when connected to the adapter, the first connection sleeve 100 is fixed by being connected to the adapter. Specifically, the first coupling sleeve 100 compresses the elastic device 300 when moving toward the ferrule 11 side to connect with the adapter, and the elastic device 300 always provides a preload to the ferrule 11 after the first coupling sleeve 100 is fixed to the adapter. The pretightening force can ensure the end face coupling effect of the two inserting cores connected with the adapter.
When the connector according to the embodiment of the present invention is an MPO (Multi-fiber Push On) connector adapted to an MT (Monolithic Ferrule), the connector further includes a second connection sleeve 200 sleeved outside the Ferrule 11, and the first connection sleeve 100 is mounted On the second connection sleeve 200.

The second connection sleeve 200 is fixed by being connected with the first connection sleeve 100, and the elastic device 300 is compressed in a space formed by the second connection sleeve 200 and the first connection sleeve 100, so that the elastic device 300 provides pre-load force to the ferrule 11. After the second connecting sleeve 200 is connected with the first connecting sleeve 100, the two cannot move relatively.
Further, the second connection sleeve 200 is provided with a first hole 230 and a second hole 240 arranged in parallel with the first hole 230 along the axial direction of the first hole 230, a step surface is formed between the first hole 230 and the second hole 240, and the ferrule abuts against the step surface 250 when entering the first hole 230 from the second hole 240.

Under the pre-tightening force of the elastic device 300, the step surface 13 of the ferrule 11 is always abutted against the step surface 250 in the second connecting sleeve 200.
The elastic means 300 may directly abut against the ferrule 11, or the elastic means 300 may be indirectly connected to the ferrule 11. As shown in fig. 2 and 3, the connector further includes a key block 500, the key block 500 is located between the ferrule 11 and the elastic means 300, and the elastic means 300 abuts against the key block 500.
The first and second connection sleeves 100 and 200 may be installed by means of a screw connection or a snap connection. In the illustrated embodiment of the present invention, the second connection sleeve 200 is snap-coupled with the first connection sleeve 100. Specifically, one of the second connection sleeve 200 and the first connection sleeve 100 is provided with a slot 210, and the other is provided with a hook 120 matching with the slot 210.
As shown in fig. 2, the cross sections of the first connection sleeve 100 and the second connection sleeve 200 are both rectangular, wherein the cross section area of the first connection sleeve 100 is smaller, and the first connection sleeve 100 can almost completely extend into the second connection sleeve 200, so that the occupied space of the connector can be reduced as much as possible. The upper and lower sidewalls of the first connection sleeve 100 are provided with hooks 120, and the slots 210 of the second connection sleeve 200 correspond to the hooks 120 one by one.
Further, the first connecting sleeve 100 includes a main body 140 and a clip arm 150, the clip arm 150 extends from the main body 140 toward the ferrule, the hook 120 or the slot 210 is located on the clip arm 150, and the first stop surface 141 is located on the main body 140. Because the hook 120 is clamped into the clamping groove 210, the first connecting sleeve 100 is deformed, and the clamping arm 150 is arranged, the clamping arm 150 is more easily deformed, so that the smoothness of the matching of the hook 120 and the clamping groove 210 is improved, and the assembly of the first connecting sleeve 100 and the second connecting sleeve 200 is facilitated.

At this time, the third stop surface 130 is disposed opposite to the second stop surface 122, and the third stop surface 130 limits the first connection sleeve 100 when moving (i.e., moving forward) to the second connection sleeve 200.
Generally, the MPO connector shown in the present invention further includes a locking mechanism 400, specifically, the locking mechanism 400 includes a reset piece 420 and housings 410, 430; the outer casings 410, 430 are mounted on the second coupling sleeve 200, and the restoring member 420 provides an elastic force to the outer casings 410, 430 along an axis thereof, the axis of the restoring member 420 being parallel to the axis O of the elastic means 300.
The restoring member 420 may be a spring, a spring plate, a part or a mechanism capable of providing elasticity. In the illustrated embodiment of the present invention, the restoring member 420 is a spring.
The locking mechanism 400 is used in conjunction with an adapter or the like to complete the connection between the optical fiber and the optical fiber, or the optical fiber and the module. The locking mechanism 400 is a push-pull locking mechanism, and the locking mechanism 400 can be locked or unlocked with the adapter, so that the connector and the adapter can be detachably mounted.
As shown in fig. 2 and 8 to 10, the casing 410 is further provided with a placement hole 411, and the restoring member 420 enters a space formed by the casing 410 and the second connecting sleeve 200 through the placement hole 411.
Alternatively, locking mechanism 400 includes two housings 410 that are separate pieces, or locking mechanism 400 includes one housing 410 that is unitary.
When the locking mechanism 400 includes two split housings 410, as shown in fig. 2-10, the housings 410 are of a generally plate-like configuration. The locking mechanism 400 includes two split housings 410 to facilitate reducing the size of the connector. Specifically, as shown in fig. 9, the second connecting sleeve 200 has a substantially square hollow structure, the upper and lower sidewalls of the second connecting sleeve 200 are respectively connected to an outer sleeve 410, and the width of the outer sleeve 410 preferably does not exceed the width of the second connecting sleeve 200. The width of the connector is reduced by the size of the two wall thicknesses of the one-piece housing 410 relative to the one-piece housing 410 of fig. 11 and 12.
Further, the jacket 410 includes two second sliding portions 413 disposed at an interval along the moving direction of the jacket 410, the second connection sleeve 200 includes two first sliding portions 220 capable of moving along the second sliding portions 413, the reset member 420 is located in the interval between the two first sliding portions 220, one end of the reset member 420 abuts against one of the second sliding portions 413, and the other end of the reset member 420 abuts against one of the first sliding portions 220.
Without limitation, as shown in fig. 7 to 9, each second sliding portion 413 includes at least two protruding portions 412, a stop portion 414, and a track groove 415 between two adjacent protruding portions 412; the stopper portion 414 is provided on the projection portion 412; the reset member 420 abuts one of the stop portions 414; when the first sliding portion 220 moves along the second sliding portion 413 toward the external attachment device, the first sliding portion 220 can abut against the stopper portion 414.
The stopper 414 of each second sliding portion 413 may have the same structure. As shown in fig. 7 and 8, the structure of the stopper 414 of each second sliding portion 413 may be different. Here, the stopper portion 414 of the second sliding portion 413 located at the front end can seal the rear end opening of the rail groove 415, and here, the rear end face 4141 of the stopper portion 414 abuts on the reset member 420, and the front end face 4142 abuts on the second sliding portion 413. The stopper 414 of the second sliding portion 413 at the rear end does not affect the openings at both ends of the rail groove 415, and is only used to abut against the first sliding portion 220 to limit the forward displacement of the outer sleeve 410. The stopper portion 414 improves the assembling accuracy between the jacket 410 and the second connection sleeve 200.
Without limitation, in order to improve the reliability of the connection between the jacket 410 and the second connection sleeve 200, the bottom width of the track groove 415 is greater than the opening width of the track groove 415, and the first sliding portion 220 has a slope 223 matched with the track groove 415.
When the second sliding portion 413 includes two protruding portions 412, each of the first sliding portions 220 includes three protrusions 221, 222 disposed at intervals. It is understood that the number of bumps depends on the number of the convex portions 413, and if the number of the convex portions 413 is n, the number of the bumps is n + 1. The track groove 415 can accommodate the corresponding middle protrusion 222, and the side wall of the middle protrusion 222 is a slope 223 inclined away from the protrusions 221 at both sides. The combination of the inclined surface 223 and the track groove 415 effectively prevents the outer sleeve 410 from being separated from the second connection sleeve 200 in the vertical direction, and improves the assembling firmness of the second sliding portion 413 and the first sliding portion 220.
Further, the protruding portion 412 is accommodated in the space between the protruding portion 222 located in the middle and the protruding portions 221 located at both sides, and the limiting effect on the second sliding portion 413 is further increased by arranging the protruding portions 221 located at both sides, so that the assembling firmness of the outer sleeve 410 and the second connection sleeve 200 is further improved.
When locking mechanism 400 includes a one-piece outer sleeve 430, as shown in fig. 11 and 12, outer sleeve 430 is a hollow structure that is open at both ends. The jacket 430 is sleeved outside the second connecting sleeve 200.
The embodiment of the invention also provides an assembling method of the connector, wherein the connector is any one of the connectors; the assembling method comprises the following steps: the elastic device 300 and the first joint cover 100 are respectively fitted to the transmission medium assembly 10.
