Auxiliary handle of MPO connector

Abstract

The utility model relates to an auxiliary handle of an MPO connector, which is characterized in that an assembly cavity for accommodating the MPO connector is arranged inside a shell along the axis direction in a penetrating manner, the front section and the middle section of the shell are flat, and the middle section and the rear section of the shell are shrunk into a slender tube in a streamline manner; and two grooves for accommodating bone positions are formed in the cavity wall of the assembly cavity corresponding to the two bone positions of an MPO unlocking piece in the MPO connector. The MPO connector protection device has the advantages that the MPO connector is protected through the auxiliary handle, so that when the auxiliary handle is pulled or pushed, the edge of the MPO connector can be effectively prevented from damaging a pull ring of an optical module, compared with a heat shrink tube, the auxiliary handle cannot fix an MPO unlocking piece and a part in the middle of an MPO together to cause unlocking failure of the MPO, and in addition, the MPO connector is prevented from being damaged by the edge of the MPO connector. When the test jumper wire of the MPO connector reaches the service life, the auxiliary handle can be detached and installed on another MPO connector for repeated use, so that the cost is saved.

Description

Technical Field

[0001] The utility model relates to the field of MPO connectors, in particular to an auxiliary handle of an MPO connector. Background Art

[0002] With the development of optical communications, MPO (Multi Push On / Pull Off, MPO) connectors occupy an important position in optical communications due to their advantages such as large number of cores, small size, and high transmission rate. They can meet the high-density wiring solutions of data centers. Optical modules with MPO interfaces are often used in conjunction with MPO connectors. When pulling or pushing the MPO unlocking piece on the auxiliary MPO connector, the edges and corners of the MPO unlocking piece will damage the pull ring of the optical module. For this reason, the current solution is to heat shrink a section of thermoplastic tube on the MPO connector, which is more troublesome. If the time is not well managed, the heat shrink tube will fix the MPO unlocking piece and the parts in the middle of the MPO together, causing the MPO unlocking to fail. Utility Model Content

[0003] The technical problem to be solved by the utility model is to provide an auxiliary handle of an MPO connector to overcome the deficiencies in the above-mentioned prior art.

[0004] The utility model provides a technical solution to the above-mentioned technical problems as follows: an auxiliary handle of an MPO connector, comprising: a shell, the shell being divided into two parts along an axis, namely a first shell and a second shell; an assembly cavity for accommodating an MPO connector is provided inside the shell along its axial direction, the front and middle sections of the shell are flat, and the middle and rear sections of the shell are streamlined and contracted into an elongated tubular shape; two grooves for accommodating bone positions are provided on the wall of the assembly cavity at two bone positions corresponding to the MPO unlocking piece in the MPO connector.

[0005] The beneficial effects of the utility model are as follows: when in use, the auxiliary handle is put on the MPO connector, and the two bone positions of the MPO unlocking piece in the MPO connector are respectively located in the two grooves, so that the assembly is convenient and quick, and then the MPO connector equipped with the auxiliary handle is docked with the MPO interface of the optical module. When pulling or pushing the auxiliary handle, since the two bone positions of the MPO unlocking piece in the MPO connector are respectively located in the two grooves, the MPO unlocking piece can be driven to move by the auxiliary handle. Since the MPO connector is protected by the auxiliary handle, and the front and middle sections of the shell are flat, and the middle and rear sections of the shell are streamlined and contracted into a slender tube, when pulling or pushing the auxiliary handle, the edges and corners of the MPO connector can be effectively prevented from damaging the pull ring of the optical module. Compared with the heat shrink tube, the auxiliary handle will not fix the MPO unlocking piece and the middle parts of the MPO together, thereby causing the MPO unlocking to fail. In addition, when the test jumper of the MPO connector reaches the end of its service life, the auxiliary handle can be removed and installed on another MPO connector for reuse, saving costs.

[0006] On the basis of the above technical solution, the present invention can also be improved as follows.

[0007] Furthermore, the first shell and the second shell are assembled into an outer shell in a snap-fit ​​manner.

[0008] A further beneficial effect of the above is that the first shell and the second shell are connected by a snap-fitting manner, so that the first shell and the second shell can be connected as a whole, thereby preventing them from falling off the MPO connector.

[0009] Furthermore, a buckle and a slot are provided on the dividing surface of the first shell, and a buckle and a slot are provided on the dividing surface of the second shell. The buckle on the first shell is snapped with the slot on the second shell, and the buckle on the second shell is snapped with the slot on the first shell.

[0010] A further beneficial effect of the above is that when the first shell and the second shell are assembled, the buckle on the first shell is engaged with the slot on the second shell, and the buckle on the second shell is engaged with the slot on the first shell, which is easy to operate and has good stability.

[0011] Furthermore, a guide post and a socket are provided on the dividing surface of the first shell, a guide post and a socket are provided on the dividing surface of the second shell, the guide post on the first shell is inserted into the socket on the second shell, and the guide post on the second shell is inserted into the socket on the first shell.

[0012] A further beneficial effect of the above is that when the first shell and the second shell are assembled, the guide post on the first shell is inserted into the socket on the second shell, and the guide post on the second shell is inserted into the socket on the first shell, so that the first shell and the second shell can be connected as a whole, thereby avoiding falling off from the MPO connector.

[0013] Furthermore, the rear end of the housing has an anti-slip structure.

[0014] A further beneficial effect of the above is that when the auxiliary handle is pulled or pushed, the anti-slip structure can prevent slipping, so that the auxiliary handle can be pulled or pushed smoothly.

[0015] Furthermore, the anti-skid structure is an anti-skid thread.

[0016] Furthermore, when the housing is sleeved on the MPO connector connected to the optical module, the rear end thereof is outside the pull ring of the optical module.

[0017] A further beneficial effect of the above is that the housing has a sufficient length, thereby facilitating the application of force to pull or push the auxiliary handle. BRIEF DESCRIPTION OF THE DRAWINGS
