Description

MPO connector male head assembling tool

Technical Field

The utility model relates to the field of MPO connector male head assembly, in particular to an MPO connector male head assembly tool.

Background

The MPO connector has the advantages of small volume, high precision and high density as a multi-core multi-channel plug-in connector, can greatly save the space and resources of optical fiber wiring, and is suitable for being applied to high-density environments such as data centers. The method is mainly characterized in that a rectangular MT insertion core with the standard diameter of 6.4mm multiplied by 2.5mm is used for accurate positioning by utilizing a left guide hole, a right guide hole and a guide needle (Pin) on the end surface of the insertion core. The assembly comprises a tail sheath, a connecting pipe, a stop ring, a spring, a guide needle, an MT inserting core, an outer frame sleeve, a dustproof cap and other assemblies. The male connector is divided into a male connector and a female connector according to the difference that the male connector is provided with a guide hole or a guide needle, wherein the male connector is provided with the guide needle with two metal pins, and the female connector is not provided with the guide needle. The connection between MPO connectors is precisely aligned by the guide pins, and the two MPO connectors that are connected to each other must be a male and a female.

After the MT ferrule at one end of the cable is ground, it needs to be assembled with each piece of MPO. In order to avoid the movement between the MT inserting core and the outer frame sleeve, the rectangular space inside the outer frame sleeve basically only allows the MT inserting core to be tightly attached and penetrated. And because the MT inserting core tail cable can be bent and moved, and the inner space of the outer frame sleeve is invisible, the MT inserting core and the outer frame sleeve are difficult to assemble.

In the prior art, the MT ferrule is continuously used for plugging and unplugging the outer frame sleeve under direct illumination, so that the MT ferrule can smoothly penetrate out through a certain probability to complete assembly. Or tweezers or a metal blade is used to penetrate into the outer frame sleeve, and the metal guide needle is poked to be matched with the rectangular space in the outer frame sleeve, so that the metal guide needle can smoothly penetrate out to complete the assembly. The first method is time-consuming and labor-consuming, and meanwhile, cables are easily damaged in the process of multiple plugging and unplugging between the MT inserting core and the outer frame sleeve; the second method has certain difficulty and time consumption, and simultaneously has great probability of touching the ground MT insertion core end face to cause defects.

When in use, the plugging part 10 of the MPO connector male assembly tool 100 is inserted into an opening at one end of the outer frame sleeve 201 far away from the optical fiber 204. The end face of the insertion part 10 is provided with a limiting hole 101 and a buffer groove 102, the limiting hole 101 is used for penetrating the guide needle 203, and the limiting hole 101 is matched with the guide needle 203, so that the mounting hole is opposite to the preset position of the guide needle 203. During installation, the guide needle 203 is aligned with the limiting hole 101, so that the guide needle 203 penetrating through the MT ferrule 202 enters the limiting hole 101, then the MT ferrule 202 is pushed into the outer frame 201, and under the guidance of the limiting hole 101, the MT ferrule 202 moves along the axial direction of the limiting hole 101, so that the movement of the MT ferrule 202 cannot deviate. After the MT ferrule 202 is pushed to a preset position in the outer frame 201, the MPO connector male head assembly tool 100 is pulled out, and the assembly of the MPO connector male head 200 can be completed. With respect to the prior art, a quick assembly of the male MPO connector 200 is achieved.

Referring to fig. 4, as a specific implementation manner of this embodiment, two limiting holes 101 are provided, the two limiting holes 101 are respectively disposed at two ends of the end surface of the insertion portion 10, and the two limiting holes 101 respectively correspond to the guide needle 203. Since the MPO connector male header 200 generally has two guide pins 203, the two guide pins 203 are arranged at intervals in the width direction of the MT ferrule 202.

Referring to fig. 4 and 5, as a specific implementation manner of this embodiment, the size of the limiting hole 101 is larger than that of the guiding needle 203, so that the guiding needle 203 extends into the limiting hole 101. The limiting hole 101 is conical, and the aperture of one end of the limiting hole, which is far away from the MT ferrule 202, is gradually reduced.

Referring to fig. 4 and fig. 5, as a specific implementation manner of the present embodiment, a size of an end surface of the plugging portion 10 is matched with a size of the MT ferrule 202, that is, the size of the end surface of the plugging portion 10 is substantially the same as the size of the MT ferrule 202, so that when the plugging portion 10 is plugged into the outer frame 201, the end surface of the plugging portion 10 is just clamped at a preset position of the MT ferrule 202.

Referring to fig. 4, as a specific implementation manner of the present embodiment, the holding portion 20 is block-shaped, the holding portion 20 is disposed at an end of the insertion portion 10 away from the MT ferrule 202, and the holding portion 20 is connected to the insertion portion 10, so as to be held by a user during assembly.
