Description

Reduced form optical-electric module draw ring tripper

Technical field

The utility model relates to the tripper of hot plug type optical-electric module in a kind of optical communication field, relates in particular to fine optical-electric module of a kind of magnetic tape trailer and electrical connection module draw-ring type unlocking device.

Background technology

At present, the tripper of hot plug tail fiber type optical-electric module mainly is plug-type, promptly inserts a pushing block above shell; Promote pushing block, the snap close shell fragment of cage is by jack-up upwards and release.The draw ring of plug-type tripper needs to use bigger power ability release.Traditional draw ring structure can't be used on the tail fiber type module, because need be with the draw ring pull-up during release, and reach unlocked position, and the draw ring handle part is just blocked by tail pipe, can not reach the purpose of release at all.In addition, must pull out the optical fiber connector earlier before the hot plug module release of traditional draw ring structure, there is certain influence in life-span of the optical fiber connector.Existing draw ring complex structure is produced difficulty.Therefore, need new ring type tripper to solve existing issue.

Summary of the invention

The purpose of this utility model just is to overcome the above-mentioned shortcoming and defect that prior art exists, and a kind of reduced form optical-electric module draw ring tripper is provided; This device is all simple utility structure of a kind of assembling and operation, adapts to the demand of communication equipment development.

The purpose of this utility model is achieved in that

With the draw ring and the new draw ring simplified structure of the integrated formation of brake(-holder) block of existing structure, the distance that release is rotated shortens, and allows the draw ring structure of magnetic tape trailer fiber module and cable link block become possibility, and automatic reset device is provided simultaneously.

As Fig. 1, the utility model is made up of base 1, loam cake 2, draw ring 3, screw 4, spring 5, briquetting 6;

Its position and annexation are:

Base 1 is connected by screw 4 with loam cake 2; Spring 5 places in two circular grooves of loam cake 2, acts between draw ring 3 and the loam cake 2; Draw ring 3 is fixed by the hole that loam cake 2 and briquetting 6 form by rotational pin; Briquetting 6 is fixed on the loam cake 2 by screw 4;

Described base 1 is a kind of rectangle cavity that matches with loam cake 2;

Described loam cake 2 is rectangle cavitys of a kind of porose and groove;

Described draw ring 3 is closed loops of a kind of square shape;

Described briquetting 6 is that a kind of following 6c and draw ring of comprising rotates the rectangular slab of stop surface 6d.

Operation principle of the present utility model is:

The dop 3d that draw ring 3 drives on the draw ring 3 in rotating process rotates simultaneously, makes dop 3d reach the purpose of release by the hole clipping of rotating the disengaging cage.Draw ring 3 is subjected to the resistance that spring 5 provides all the time in this course, and when draw ring 3 was finished release action external force and unclamped draw ring, spring 5 just made draw ring 3 reset.The draw ring that draw ring 3 is run into briquetting 6 rotates stop surface 6d stop motion, finishes the action that automatically resets to the service position.

The utility model has following advantage:

1, collection tumbler and brake apparatus are positioned at one, have optimized structure, have simplified the difficulty of processing of part, have improved the reliability of part;

2, the installation of module, unlocking operation meet people's daily habits fully, need not painstakingly memorize;

3, the assembling of module is very simple, and assembling speed can be guaranteed;

4, draw ring can self-return, need not manual reversion.

Embodiment

Describe in detail below in conjunction with drawings and Examples:

One, the structure of non-standard component

1, base 1

As Fig. 2, base 1 is a kind of rectangle cavity that matches with loam cake 2.

2, loam cake 2

As Fig. 3, loam cake 2 is rectangle cavitys of a kind of porose and groove; There is screw connecting hole 2a on the upper left side of

loam cake

2,2b, draw ring rotational pin location notch 2c, draw ring dop sink to groove 2d, briquetting fixing threaded hole 2e, spring location notch 2f above the left end.

3, draw ring 3

As Fig. 4, draw ring 3 is closed loops of a kind of square shape, and draw ring 3 is provided with spring location notch 3a, rotational pin 3b, medial surface 3c, dop 3d;

4, briquetting 6

As Fig. 5, briquetting 6 is that a kind of following 6c and draw ring of comprising rotates the rectangular slab of stop surface 6d; The two ends of following 6c are respectively arranged with draw ring rotational pin location notch 6a; The centre of following 6c is provided with screw hole 6b.

Two, cooperation of the present utility model

1, the cooperation of loam cake 2, draw ring 3, screw 4, spring 5 and briquetting 6

Spring 5 is installed in the spring location notch 2f of loam cake 2; One end of spring 5 acts on loam cake 2, and the other end acts on the spring location notch 2f of draw ring 3; The rotation pin-and-hole positioning and fixing that the rotational pin 3b of draw ring 3 is made up of the draw ring rotational pin location notch 2c of the draw ring rotational pin location notch 2c of briquetting 6 and loam cake 2; The draw ring of briquetting 6 rotates stop surface 6d restriction draw ring 3 and is in correct position in working order down; Briquetting 6 is fixing by screw 4 and loam cake 2.
