Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the MPO connector 10 includes a housing 11, a front sleeve 12 and an optical fiber jumper 13, the front sleeve 12 is sleeved on an end portion of the optical fiber jumper 13, the housing 11 is sleeved on the front sleeve 12, two sides of the housing 11 are respectively provided with symmetrically arranged circular holes 111, a rear end protrusion 121 is arranged at a rear end of the front sleeve 12, a limiting gap 100 is formed between the housing 11 and the rear end protrusion 121, the housing 11 can slide along the front sleeve 12 under the action of an external force, and the width of the limiting gap 100 is reduced in the sliding process, so as to unlock the MPO connector 10.

As shown in fig. 3 and 4, the MPO connector with anti-moving back type anti-unlocking structure of the present invention includes the MPO connector 10 and the latch 20, the latch 20 is rotatably connected to the housing 11 through two round holes 111, and the latch 22 has a limiting portion 21. The lock catch 20 can rotate to enable the limiting part 21 to be embedded into the limiting gap 100, so that the relative movement of the shell 11 relative to the front sleeve 12 is limited through the limiting part 21, and the lock catch 20 is in a locking state; the lock catch 20 is rotated to separate the limiting portion 21 from the limiting gap 100, the limitation of the sliding of the housing 11 is released, the lock catch 20 is in an unlocked state, and at this time, the MPO connector can be unlocked by sliding the housing 11.

In order to prevent the lock catch 20 from being accidentally touched, when the limiting portion 21 is inserted into the limiting gap 100, the main body of the limiting portion 21 does not protrude out of the limiting gap 100. In order to facilitate the operation of the position-limiting portion 21, the position-limiting portion 21 has a protrusion extending in a direction away from the front cover 12 when the position-limiting portion 21 is fitted into the position-limiting gap 100. The user can conveniently rotate the latch 20 through the protrusion.

Specifically, hasp 20 has the buckling parts 22 that are located spacing portion 21 both sides, and two buckling parts 22 all perpendicular to spacing portion 21, when buckling parts 22 imbed in spacing clearance 100, two buckling parts 22 are laminated in the both sides of MPO connector 10 from bilateral symmetry respectively, form elasticity and hold the structure tightly, prevent to leave spacing clearance 100 easily under the circumstances that spacing portion 21 is touched, improve hasp 20's anticreep performance. Specifically, both the engaging portions 22 are attached to the surfaces of the housing 11 and the front cover 12.

The lock catch 20 further has two connectors 23, the two connectors 23 are respectively inserted into the two round holes 111, and the lock catch 20 is rotatably connected with the two round holes 111 through the two connectors 23. The lock catch 20 is connected to the housing 11 in both the locked state and the unlocked state, and the lock catch 20 is not separated from the housing 11 without being disassembled, so that the lock catch 20 can be prevented from being lost.

The lock catch 20 can be made of metal, alloy or plastic, and is not easy to damage in a common use environment and has long service life. The lock catch 20 has high strength and certain elasticity, so that the functions of limiting and holding tightly can be realized, and the disassembly and the assembly are convenient.

Further, the latch 20 is preferably a unitary structure. For example, the lock 20 is formed by bending a metal rod, wherein two connectors 23 are formed by bending two ends of the metal rod, two buckling parts 22 are formed by bending the metal rod, the limiting part 21 is formed by bending the middle part of the metal rod, and the protrusion of the limiting part 21 is formed by bending the metal rod. The latch 20 of the integral structure has a firmer structure, is not easy to break, has a longer service life, is light in weight and small in size, and can effectively reduce the overall weight and the volume of the MPO connector 10 due to the adoption of the metal rod bending type latch 20.

As shown in fig. 5, the MPO connector 10 with the latches 20 mounted thereon is assembled with the MPO adapters 30 to form an assembled product as shown in fig. 6. The limiting part 21 is embedded into the limiting gap 100 by rotating the lock catch 20, so that the shell 11 can be limited, the shell 11 is prevented from sliding, the shell 11 cannot be pulled out manually, and the unlocking prevention function is realized. When the connection between the MPO connector 10 and the MPO adapter 30 needs to be released, the lock catch 20 needs to be rotated to move the limiting portion 21 out of the limiting gap 100 to the state shown in fig. 7, and the lock catch 20 is released from limiting the housing 11, so that the unlocking of the MPO connector can be realized. The arrangement of the latch 20 does not affect the self-locking function of the connection between the MPO connector 10 and the MPO adapter 30, and the connection reliability between the MPO connector 10 and the MPO adapter 30 is not affected.

The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
