JPS5840508A - High-density mounting type optical fiber connector - Google Patents

Abstract

PURPOSE:To mount optical fibers at a high density and to improve operability by making plural connecting holes equal to the number of opposing plugs in only one adapter and simplifying the coupling mechanism between each plug and adapter. CONSTITUTION:An optical fiber connector is constituted by plugs each of which consisting of a plug center element 6, a plug fixing and operating part 7 for enabling the plug to move in the axial and peripheral directions on the basis of the plug center element 6 and fixing the plug center element 6 by a fixing pawl 15 fitted to the leading end of the part 7 when the plug center element 6 is inserted into an adapter and a spring mechanism part 8 for applying a fixed pressure between the plug center element and the fixing and operating part and an adapter consisting of a connecting part 17 having the connecting holes equal to the number of opposing plugs and a supporting part 10 for fixing the inserted plug, so that the connector can mount many optical fibers at a high density and its operability is also improved.

Description

DETAILED DESCRIPTION OF THE INVENTION Book 11@ has many books O light 7 fiber 1. **Effectively efficient (continuing round high-density mounting type optical fiber connectors).

I/l1IWJ#cFi, a general conceptual diagram of the structure of a conventional optical 7-iper connector is shown.

1.3 is the optical 7-eyeper, 3 and 4 are plugs, and 5 is an adapter. Each plug has 3.4Kd one through hole,
An optical fiber 1.2 is inserted into it. The adapter IK also has one through hole, into which a plug with a diameter of 1 to 1 is inserted so as to butt the end surface of the optical fiber.

The plugs 3 and 4 are removably attached to the adapter S), and both are fixed to each other by a screw mechanism.

Another general conceptual diagram of the structure of a conventional optical seven-eye power connector is shown in FIG. The difference from the first 110 scene is that snow has been inserted. Friends, complex mold book 0 JIl:, 7 eye pa 1. Z is for Prada! , 4C)
It is possible to attach, detach, and connect to the adapter 5 all at once by operation.

In the optical fiber connector having the above structure, when the shape of each optical fiber OVa changes frequently, the plug 3゜4 is connected to the optical fiber connector for each optical fiber connector. If the number is large, the overall structure becomes complicated, the scale is very hot, and the economy is bad.9 To solve this problem, as shown in %K31mK, Used when there are many connections %/
&! [In one example, a method has been proposed in which a plurality of conventional connectors are simply connected using an adapter section. In this way, it is true that the packaging density will be improved and the adapter S will be shared and the h rounding economy will be achieved, but since the Prada 3.4 leapfrog O separation is close, the operability will be poor. I have a problem, friend.

In this article, we will solve these shortcomings by integrating multiple optical seven-eye adapters into one unit.
In addition to making the plug smaller and more cylindrical, the plug fixing mechanism is simplified to improve the repeatability of the plug. The purpose is to provide an optical fiber connector consisting of a plug attached to the tip of an optical fiber for controlling and controlling the tip, and a larger adapter that faces the plug and holds the plug in place. , the plug is formed into a controllable shape with a plug core and a scissor grader core, and is movable in the axial direction and circumferential direction with reference to the plug or core, and a fixing claw is provided at the tip. I'm tired
To ensure that a constant pressure is applied between the Prada fixing/operating part to maintain a constant state when inserted into the J plug or the child T + FFL adapter, and the plug core and the -K plug fixing/operating part. The adapter comprises a connecting part having the same number of pleated holes as the number of opposing faces of the plug, and a holding part for identifying the plug into which the adapter can be inserted. Features.

Hereinafter, based on the embodiments shown in the drawings, A related to the present invention will be explained.
! I will explain about the I & mounting type optical 7 eye computer connection.

What is noteworthy here is Prada's claws! s and the adapter 0 connection part 17 are both oval in shape, and the former is smaller in shape than the latter, so the former has a specific rotation position with respect to the axis.

Therefore, when inserting the Prada into the adapter and threading, place the plug in the direction that allows it to pass through the claws 11!7 IIX threading section 17. I

This position is maintained by zero force, and the connection between the plug and adapter is slowed down. Before removing the plug from the adapter, the IIK should be able to perform the traverse and mine operation.

In addition, in Fig. 4-), the connecting part 17 is oval, but it must be made into a T-shape as shown in Fig. After 70 rotations of the operation part, if there is a part that can be entangled in the holding part 1, then it is necessary to connect it to 4 and connect it to 1117 to make it 1').

It does not have to be a helical O spring like the body), but it can also be something like a rubber chain that also functions as a spring.
It is preferable that the stopper 12 and the claw 1g be designed so that they exert a force on them that causes them to repel each other.

Furthermore, although plugs and adapters are depicted as being integrated in Figure 1, when they are actually manufactured, they can be made by combining individual parts.

The above description is based on the circular embodiment shown in the drawings. As can be seen, in the device, the same number of connection holes as the number of opposing holes for multiple pairs of O-graders are connected to a single adapter! exists in
In addition, since the coupling mechanism of the plug and adapter is TAX, it can be used at high density when connecting a large number of optical fibers, and has the advantage of excellent operability.
