Detailed Description

In order to make the objects, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the drawings of the embodiments of the present invention. It is to be understood that the embodiments described are only a few embodiments of the present invention, and not all embodiments. 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", "vertical", "horizontal", "top", "bottom", "inner", "outer", and the like indicate orientations or positional relationships based on the orientation or positional relationships shown in fig. 4. "front" refers to a direction close to the coupling end of theferrule 11, and "rear" refers to a direction away from the coupling end of theferrule 11.

The embodiment of the invention provides an assembly body for holding a ferrule, which comprises a first connectingsleeve 200 for holding theferrule 11 andouter sleeves 410 respectively arranged at two sides of the first connectingsleeve 200; theouter sleeve 410 is capable of being connected to an external device to lock the assembly body by moving relative to thefirst connection sleeve 200 in a first direction; movement of theouter sleeve 410 relative to thefirst sleeve 200 in a direction opposite the first direction disengages the external device to unlock the fitting body.

Thefirst connection sleeve 200 has a hollow structure with two open ends. As shown in fig. 2 and 8, theoptical fiber 12 and theferrule 11 constituting theferrule assembly 10 are inserted into thefirst connection sleeve 200, and the end of theferrule 11 can be exposed outside thefirst connection sleeve 200 for coupling connection. Theouter jacket 200 need not be installed around the circumference of thefirst coupling sleeve 200, but only needs to be installed at both sides of thefirst coupling sleeve 200, and a partial region on the circumference of thefirst coupling sleeve 200 is not connected to theouter jacket 200, thereby reducing the size of the assembly body and further reducing the overall size of the connector.

Further, thefirst connection sleeve 200 includes a first slidingportion 220, theouter sleeve 410 includes a second slidingportion 413, and the first slidingportion 220 is slidably connected to the second slidingportion 413. Theouter case 410 is slidable in a first direction with respect to thefirst coupling sleeve 200, and in a direction opposite to the first direction, by the engagement of the second slidingportion 413 with the first slidingportion 220. So as to lock or unlock theouter case 410 with an external device such as an adapter.

Preferably, the twohousings 410 installed at both sides of thefirst coupling sleeve 200 are of a split structure. Fig. 3, 4, 7, 8 and 11 and 13 exemplarily show twoouter casings 410 separated, theouter casings 410 having a substantially plate shape. The twohousings 410, which are separated, are physically independent from each other, and the twohousings 410 may have the same structure for convenience of manufacture.

Preferably, twoouter cases 410 are installed at opposite sides of thefirst coupling sleeve 200, respectively. Taking the first connectingsleeve 200 with a square cross-sectional shape as an example, without limitation, as shown in fig. 3 to 5, twoouter sleeves 410 are respectively installed on the upper and lower side surfaces of the first connectingsleeve 200, and a partial area on the peripheral side of the first connectingsleeve 200 is not connected with theouter sleeves 410, so that the width dimension of the assembly body in the second direction is reduced. In contrast to the prior art assembly of casing b and head receiving portion a of fig. 1, the reduced size of the assembly of the present embodiment is at least two thickness values of casing b.

Further, the width of theouter case 410 in the second direction is less than or equal to the width of thefirst coupling sleeve 200 in the second direction; the second direction is perpendicular to the first direction. As shown in fig. 3, the width of theouter case 410 in the second direction is equal to the width of thefirst coupling sleeve 200 in the second direction. Due to the arrangement, the situation that the width of the assembly body along the second direction is larger due to the fact that theouter sleeve 410 protrudes out of the first connectingsleeve 200 can be avoided.

In order to facilitate the resetting of theouter sleeve 410 in the push-pull moving process, the assembly body further includes a resettingmember 420 corresponding to theouter sleeve 410 one by one, the resettingmember 420 is located in the accommodating space formed by theouter sleeve 410 and the first connectingsleeve 200, and the resettingmember 420 abuts against theouter sleeve 410 to provide an elastic force to theouter sleeve 410.

The restoringmember 420 may be a spring, a spring plate, a part or a mechanism capable of providing elasticity. Specifically, as shown in fig. 4, 7 and 8, the restoringmember 420 is a spring. The restoringmember 420 provides an elastic force to theouter case 410 along its axis.

In some embodiments of the present invention, thehousing 410 is provided with aplacement hole 411 communicating with the accommodation space, and thereset member 420 enters the accommodation space through theplacement hole 411. When the first connectingsleeve 200, theouter sleeve 410 and thereset piece 420 are assembled, theouter sleeve 410 can be firstly installed on the first connectingsleeve 200, and then thereset piece 420 is installed through the placinghole 411; thereset piece 420 can be installed on the first connectingsleeve 200 firstly, and then theouter sleeve 410 is installed, so that the assembling sequence is reduced, and the professional requirement on field installation is reduced. The assembly body can be pre-installed, and the convenience of transportation and field installation is improved.

Further, theouter casing 410 includes two second slidingportions 413, the first connectingcasing 200 includes two first slidingportions 220, the two second slidingportions 413 and the two first slidingportions 220 are both disposed at intervals along the first direction, the accommodating space includes aninterval space 224 between the two first slidingportions 220, and thereset piece 420 is located in theinterval space 224.

Further, one end of thereset member 420 abuts against one of the second slidingportions 413, and the other end of thereset member 420 abuts against one of the first slidingportions 220. On the basis of fig. 4, when an external force is applied to thehousing 410 to move thehousing 410 in a direction opposite to the first direction, the second slidingportion 413 located at the front of thehousing 410 compresses thereset member 420, thehousing 410 is separated from the external device such as an adapter or a device to perform unlocking, and after the external force is removed, thehousing 410 is restored to the original position by the elastic restoring force of thereset member 420 so as to be locked next time.

In some embodiments of the present invention, each of the second slidingportions 413 includes at least twoprotrusions 412, astopper portion 414, and atrack groove 415 between twoadjacent protrusions 412; the first slidingportion 220 slides along therail groove 415; thestopper portion 414 is provided on theprojection portion 412; one of thestopper portions 414 abuts against thefirst slide portion 220. When the assembly is provided with thereset member 420, thestopper portion 414 abuts against thereset member 420 at the same time.

Thestopper 414 of each second slidingportion 413 may have the same structure. As shown in fig. 5 and 6, the structure of thestop portion 414 of each second slidingportion 413 may be different. Here, thestopper portion 414 of the second slidingportion 413 located at the front end can seal the rear end opening of therail groove 415, and here, therear end face 4141 of thestopper portion 414 abuts on thereset member 420, and thefront end face 4142 abuts on the second slidingportion 413. Thestopper 414 of the second slidingportion 413 at the rear end does not affect the openings at both ends of therail groove 415, and is only used to abut against thefirst coupling sleeve 200 to limit the forward displacement of theouter sleeve 410. Thestopper 414 improves the accuracy of the fit between theouter case 410 and the firstjoint housing 200.

The first slidingportion 220 includes aslider 222, and theslider 222 slides in thetrack groove 415. When the assembly body is provided with thereset piece 420, theslider 222 abuts against thereset piece 420. It is understood that the number ofsliders 222 depends on the number of theprotrusion 413, and if the number of theprotrusion 413 is n, the number ofsliders 222 is n-1, and n is a positive integer.

Without limitation, each first slidingportion 220 further includes aprotrusion 221 respectively located at both sides of theslider 222. As shown in fig. 5 to 7, when the second slidingportion 413 includes two protrudingportions 412, the first slidingportion 220 includes oneslider 222, theslider 222 slides in thetrack groove 415, and thereset member 420 can abut against theslider 222 of the second slidingportion 413 located at the rear end.

Further, theside wall 223 of theslider 222 has astopper 2231 protruding outward. As shown in fig. 5, the upper portion of theside wall 223 of theslider 222 is inclined away from theprotrusion 221, the lower portion of theside wall 223 of theslider 222 is inclined toward theprotrusion 221, and the middle portion of theside wall 223 has astopper 2231. In addition, theside wall 223 of theslider 222 may be a slope inclined toward thebump 221, that is, a space with a small top and a large bottom is formed between theslider 222 and thebump 221, and in this case, thestopper 2231 may be located at an upper portion of theside wall 223.

The engagement between the position-limitingportion 2231 and thetrack groove 415 effectively prevents theouter case 410 from being separated from thefirst coupling sleeve 200 in the vertical direction, thereby improving the assembling stability of the second slidingportion 413 and the first slidingportion 220.

Further, theprotrusion 412 is accommodated in the space between theslider 222 and theprotrusion 221, and theprotrusion 221 located on both sides further increases the limiting effect on the second slidingportion 413, so as to further improve the firmness of the assembly of theouter sleeve 410 and the first connectingsleeve 200.

The embodiment of the present invention further provides a connector, wherein theconnector 600 includes thesecond connection sleeve 100, theelastic device 300, and any one of the above-mentioned assemblies; the second connectingsleeve 100 is installed on the first connectingsleeve 200, one end of theelastic device 300 is abutted against theferrule 11 located in the first connectingsleeve 200, the other end of theelastic device 300 is abutted against the second connectingsleeve 100, and theelastic device 300 provides a pretightening force to theferrule 11.

The elastic means 300 is located in the space formed by thefirst coupling sleeve 200 and thesecond coupling sleeve 100, and thus, the width of the assembly body determines the width of theconnector 600. As can be seen from the above embodiments, the size of theconnector 600 is also reduced by providing theouter cases 410 on both sides of thefirst coupling sleeve 200, respectively.

As shown in fig. 11 and 12, the size of theconnector 600 of the embodiment of the present invention is smaller than that of the prior art adapter using the same adapter. Specifically, the width D1 of theconnector 600 according to the embodiment of the present invention in the second direction is 4.2cm, while the width D2 of the connector D according to the prior art is 7.7cm, on the premise that the connector D according to the prior art is identical to theconnector 600 according to the embodiment of the present invention except that the housing has a cylindrical structure with both ends open. Accordingly, the corresponding size of the adapter to which theconnector 600 of the present invention is connected may be reduced relative to the adapter shown in fig. 11 and 12.
