Detailed ways

In order to make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the technical solutions of the embodiments of the present disclosure will be described clearly and completely in conjunction with the accompanying drawings of the embodiments of the present disclosure. Obviously, the described embodiments are a part of the embodiments of the present disclosure, rather than all the embodiments. Based on the described embodiments of the present disclosure, all other embodiments obtained by those skilled in the art fall within the protection scope of the embodiments of the present disclosure.

In the description of the embodiments of the present disclosure, it should be understood that the terms "upper", "lower", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. indicate The orientation or position relationship is based on the orientation or position relationship shown in FIG. 4. "Front" refers to the direction close to the coupling end of the ferrule 11, and "rear" refers to the direction away from the coupling end of the ferrule 11.

The embodiment of the present disclosure provides an assembly body for holding a ferrule. The assembly body includes a first connecting sleeve 200 configured to hold the ferrule 11 and an outer sleeve 410 respectively installed on both sides of the first connecting sleeve 200; the outer sleeve 410 is opposite to each other. The first connecting sleeve 200 can be moved in a first direction to be connected with an external device to lock the assembly; the outer sleeve 410 can be moved in a direction opposite to the first direction relative to the first connecting sleeve 200 and can be separated from the external device to unlock the assembly.

The first connecting sleeve 200 is a hollow structure with open ends. As shown in FIGS. 2 and 8, the ferrule assembly 10 composed of the optical fiber 12 and the ferrule 11 passes through the first connecting sleeve 200, and the end of the ferrule 11 can be exposed outside the first connecting sleeve 200 for coupling connection. The outer jacket 200 does not need to be installed around the peripheral side of the first connecting sleeve 200, but only needs to be installed on both sides of the first connecting sleeve 200. Some areas on the peripheral side of the first connecting sleeve 200 are not connected to the outer sleeve 200, thereby reducing assembly The size of the body and the overall size of the connector are also reduced.

Further, the first connecting sleeve 200 includes a first sliding portion 220, and the outer sleeve 410 includes a second sliding portion 413, and the first sliding portion 220 and the second sliding portion 413 are slidably connected. Through the cooperation of the second sliding portion 413 and the first sliding portion 220, the outer sleeve 410 is slidable relative to the first connecting sleeve 200 in a first direction and a direction opposite to the first direction. In order to realize the locking or unlocking of the outer casing 410 and the adapter and other external devices.

Preferably, the two jackets 410 installed on both sides of the first connecting sleeve 200 have a split structure. 3, 4, 7, 8, and 11 and 13 exemplarily show two separate jackets 410, and the jackets 410 are generally plate-shaped. The two split jackets 410 are physically independent of each other. For ease of manufacture, the two jackets 410 can have the same structure.

Preferably, the two jackets 410 are respectively installed on two opposite sides of the first connecting sleeve 200. Taking the first connecting sleeve 200 with a square cross-sectional shape as an example, without limitation, as shown in FIGS. 3 to 5, two outer sleeves 410 are respectively installed on the upper and lower sides of the first connecting sleeve 200, and the first connecting sleeve 200 There are some areas on the peripheral side that are not connected to the outer sleeve 410, thereby reducing the width dimension of the assembly in the second direction. Compared with the assembly composed of the outer shell b and the head receiving part a in the prior art in FIG. 1, the reduced size of the assembly in the embodiment of the present disclosure is at least two thickness values of the outer shell b.

Further, the width of the outer sleeve 410 in the second direction is less than or equal to the width of the first connecting sleeve 200 in the second direction; the second direction is perpendicular to the first direction. As shown in FIG. 3, the width of the outer sleeve 410 in the second direction is equal to the width of the first connecting sleeve 200 in the second direction. This arrangement can prevent the outer sleeve 410 from protruding from the first connecting sleeve 200 to prevent the assembly body from having a larger width in the second direction.

In order to facilitate the resetting of the jacket 410 during the push-pull movement, the assembly body further includes a reset piece 420 corresponding to the jacket 410 one-to-one. The reset piece 420 is located in the accommodation space formed by the jacket 410 and the first connecting sleeve 200, and the reset piece 420 and the jacket The 410 abuts to provide elastic force to the jacket 410.

The restoring member 420 may be a spring, an elastic piece, a part or mechanism capable of providing elasticity. Specifically, as shown in FIG. 4, FIG. 7 and FIG. 8, the restoring member 420 is a spring. The restoring member 420 provides elastic force to the outer sleeve 410 along its axis.

In some embodiments of the present disclosure, the jacket 410 is provided with a placement hole 411 communicating with the accommodating space, and the reset member 420 enters the accommodating space through the placement hole 411. When the first connecting sleeve 200, the outer sleeve 410 and the resetting piece 420 are assembled, the outer sleeve 410 may be installed on the first connecting sleeve 200 first, and then the resetting piece 420 may be installed through the placement hole 411; or the resetting piece 420 may be installed on the first connecting sleeve. A jacket 410 is installed on the connecting sleeve 200, which reduces the assembly sequence and reduces the professional requirements for on-site installation. The assembly can be pre-installed, which improves the convenience of transportation and on-site installation.

Further, the outer jacket 410 includes two second sliding parts 413, the first connecting sleeve 200 includes two first sliding parts 220, and the two second sliding parts 413 and the two first sliding parts 220 are both spaced apart along the first direction. The accommodating space includes a space 224 between the two first sliding parts 220, and the restoring member 420 is located in the space 224.

Further, one end of the resetting member 420 abuts against one of the second sliding parts 413, and the other end of the resetting member 420 abuts against one of the first sliding parts 220. On the basis of FIG. 4, when an external force is applied to the outer sleeve 410 to move the outer sleeve 410 in a direction opposite to the first direction, the second sliding portion 413 on the outer sleeve 410 at the front compresses the reset member 420, and the outer sleeve 410 is connected to an adapter or device. The device is separated to achieve unlocking. After the external force is removed, under the elastic restoring force of the restoring member 420, the jacket 410 returns to the initial position for the next lock.

In some embodiments of the present disclosure, each second sliding portion 413 includes at least two protrusions 412, a stop portion 414, and a track groove 415 located between two adjacent protrusions 412; The sliding part 220 slides along the track groove 415; the stop part 414 is disposed on the protruding part 412; one of the stop parts 414 abuts the first sliding part 220. When the assembly body is provided with the reset member 420, the stop portion 414 abuts against the reset member 420 at the same time.

The structure of the stop portion 414 of each second sliding portion 413 may be the same. As shown in FIGS. 5 and 6, the structure of the stop portion 414 of each second sliding portion 413 may also be different. Wherein, the stop portion 414 of the second sliding portion 413 at the front end can seal the rear end opening of the track groove 415, where the rear end surface 4141 of the stop portion 414 is in contact with the restoring member 420, and the front end surface 4142 is in contact with the second The sliding part 413 abuts. The stop portion 414 of the second sliding portion 413 at the rear end has no effect on the openings at both ends of the track groove 415, and is only configured to abut the first connecting sleeve 200 to limit the forward displacement of the outer sleeve 410. The stop portion 414 improves the assembly accuracy between the outer sleeve 410 and the first connecting sleeve 200.

The first sliding part 220 includes a sliding block 222, and the sliding block 222 slides in the track groove 415. When the assembly body is provided with the resetting member 420, the sliding block 222 abuts against the resetting member 420. It can be understood that the number of sliders 222 is determined according to the protrusions 413. If the number of protrusions 413 is n, the number of sliders 222 is n-1, and n is a positive integer.

Without limitation, each first sliding portion 220 further includes protrusions 221 located on both sides of the sliding block 222, respectively. As shown in Figures 5 to 7, when the second sliding part 413 includes two protruding parts 412, the first sliding part 220 includes a sliding block 222, and the sliding block 222 slides in the track groove 415, and the resetting member 420 can interact with each other. The slider 222 of the second sliding portion 413 at the rear end abuts.

Further, the side wall 223 of the slider 222 has a limiting portion 2231 protruding outward. As shown in FIG. 5, the upper part of the side wall 223 of the slider 222 is inclined away from the protrusion 221, the lower part of the side wall 223 of the slider 222 is inclined toward the protrusion 221, and the middle part of the side wall 223 has a limiting portion 2231. In addition, it is also possible that the side wall 223 of the slider 222 is an inclined surface that is inclined toward the protrusion 221, that is, the slider 222 and the protrusion 221 are formed with a large upper and lower interval. At this time, the limiting portion 2231 is located on the side. The upper part of the wall 223.

The arrangement of the limiting portion 2231 and the track groove 415 effectively prevents the outer casing 410 from being separated from the first connecting sleeve 200 in the vertical direction, and improves the firmness of the assembly of the second sliding portion 413 and the first sliding portion 220.

Further, the protrusion 412 is accommodated in the interval between the slider 222 and the protrusion 221, and the positioning of the second sliding part 413 is further increased by arranging the protrusions 221 on both sides, thereby further improving The firmness of the assembly of the outer sleeve 410 and the first connecting sleeve 200.

The embodiment of the present disclosure also provides a connector. The connector 600 includes a second connecting sleeve 100, an elastic device 300, and any of the aforementioned assemblies; the second connecting sleeve 100 is mounted on the first connecting sleeve 200, and the elastic device 300 One end of the elastic device 300 abuts against the ferrule 11 located in the first connecting sleeve 200, the other end of the elastic device 300 abuts against the second connecting sleeve 100, and the elastic device 300 provides a pre-tightening force to the ferrule 11.

The elastic device 300 is located in the space formed by the first connecting sleeve 200 and the second connecting sleeve 100. Therefore, the width of the assembly determines the width of the connector 600. It can be seen from the above embodiment that the size of the connector 600 is also reduced by arranging the outer jackets 410 on both sides of the first connecting sleeve 200 respectively.

As shown in FIGS. 11 and 12, using the same adapter, the size of the connector 600 of the embodiment of the present disclosure is smaller than the size of the adapter in the prior art. Specifically, in the prior art, the connector d in the prior art adopts a cylindrical structure with open ends at both ends, and the other is the same as the connector 600 of the embodiment of the present disclosure. The width of the connector 600 of the embodiment of the present disclosure along the second direction is D1 is 4.2 cm, while the corresponding width D2 of the prior art connector d is 7.7 cm. Therefore, compared with the adapter shown in FIGS. 11 and 12, the corresponding size of the adapter connected to the connector 600 of the embodiment of the present disclosure can also be reduced.

As shown in FIG. 13, using the connector 600 of the embodiment of the present disclosure, more plug-in ports can be provided in the same area f on the device e to connect more connectors 600.

The shape of the projection of the elastic device 300 along the axis O is a substantially C-shape. The optical fiber 12 can enter the elastic device 300 through the first notch 310, and enter the first connecting sleeve 200 through the second notch 110. This post-installation mode does not require the ferrule 11 to be removed. The assembly of the connector 600 can be completed under the condition that the connection relationship remains unchanged, which avoids the waste of materials, improves the assembly efficiency of the connector 600, and shortens the construction period.

As shown in FIG. 4, the first connecting 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. One of the first hole 230 and the second hole 240 A step surface 250 is formed therebetween. When the ferrule 11 enters the first hole 230 from the second hole 240, the step surface 13 on the ferrule 11 abuts the step surface 250.
