Embodiment

Describe the utility model most preferred embodiment in detail below in conjunction with accompanying drawing.

By the decomposing schematic representation of release resetting means shown in Figure 1 as can be known, this device comprises: a base 10, metal clips folder 20, one pressing plate 30, a draw ring 40, a gland 50 and an elasticity vest 60.

By base shown in Figure 2 10, this pedestal is provided with a pair of threaded hole 11, LC type connector port one 2, first shaft hole 13, second shaft hole 14, be used to hold the installation chucking position 16 of the sinking cavity 15 and the vest 60 of metal clips folder 20 and pressing plate 30.

As shown in Figure 3 metal clips folder 20 device that is one of the forming, comprise underframe 21 and be the shell fragment 22 of an angle with this underframe, shell fragment 22 1 ends are connected with underframe 21, and the other end is a free end 23, when the free end 23 of shell fragment 22 was subjected to downward pressure, shell fragment 22 closed up towards the underframe 21 of bottom.Metal clips folder 20 also can replace by a compressible spring.

The device that is one of the forming of pressing plate 30 as shown in Figure 4, its front end upper surface forms downward dip plane 31, and the centre is provided with movable rotation-shaft 33, and the center, rear end is provided with open slot 32, is positioned at these open slot both sides and is provided with and is used for the upwards contact 34 of jack-up cage elastic collet.

The device that is one of the forming of draw ring 40 as shown in Figure 5, its center that is rotationally connected axle 41 is provided with a cam 42, and this cam can be replaced by a pivoted arm.

The device that is one of the forming of gland 50 as shown in Figure 6 comprises protecgulum 51 and bonnet 52, the preceding threaded hole 11 corresponding threaded holes 53 that are covered with base 10, and bonnet 52 centers are provided with cavity 54, and the back edge of this cavity is provided with the module tapered end 55 to upper process.

The erection sequence of above-mentioned release resetting means is as follows:

One, the underframe 21 of metal clips folder 20 is lain against in the bottom of sinking cavity 15 of base 10, the free end 23 of its shell fragment 22 is towards the port direction of pedestal 10.

Two, the front end with pressing plate 30 aligns with the free end 23 of shell fragment 22 by last from putting down, dip plane 31 upwards, its movable rotation-shaft 33 places in second shaft hole 14 of pedestal 10, and this rotating shaft makes the front and back end of pressing plate 30 can be up and down as fulcrum, and the rear end is protruding in the cavity 15 that sinks.

Three, the rotating shaft 41 with draw ring 40 places in first shaft hole 13 of base 10, and when rotating draw ring 40, the cam 42 in its rotating shaft 41 can promote pressing plate 30 front end dip plane 31 downwards, and making the rear end of pressing plate 30 is that fulcrum swings up and down with its movable rotation-shaft 33.

Four, the threaded hole 53 of gland 50 is aimed at downwards with base 10 threaded holes 11 compressed, it is firm by bolt (accompanying drawing is not shown) gland 50 to be connected with base 10, make the front end 51 of gland 50 Spring sheet clip 20, pressing plate 30 and draw ring 40 are fixed in the sinking cavity 15 of base 10, module tapered end 55 places in the open slot 32 of pressing plate 30 rear ends, after gland is fixing, draw ring 40 can rotate in first shaft hole 13 of base 10, and drives the open slot 32 of pressing plate 30 rear ends and the contact 34 of both sides swings up and down.

Five, the chucking position 16 of vest 60 being aimed at base 10 is fixed.

Promptly finish the installation of tripper by above-mentioned five steps.

The execution of above-mentioned release resetting means action is as follows: when module is in as shown in Figure 7 state, be that draw ring 40 is when being fastened on the end face of base 10, because metal clips folder 20 is in initial open configuration, the cam 42 that draw ring 40 is positioned under the gland 50 is in initial position at this moment, apply downward pressure for the dip plane 31 of pressing plate 30 front ends, rotating shaft 33 with pressing plate 30 is a fulcrum, the front end of pressing plate 30 is freely tilted upward, the downward sedimentation in rear end, contact 34 tops of open rearward end groove 32 both sides are because of being lower than the top of groove inner lock head 55 at this moment, make the tapered end high projection that in open slot 32, makes progress, when module is inserted cage, the lockhole that tapered end 55 passes the cage shell fragment blocks, and the optical module in the cage is in the lock state.

When module is in as shown in Figure 8 state, promptly upwards rotating draw ring 40 makes it turn to 60 degree angles when above from initial position, the cam 42 that drives in the rotating shaft 41 on it rotates, rotate in second shaft hole 14 of base 10 with the rotating shaft 33 that promotes pressing plate 30, force on 31 sedimentations of pressing plate front end, the rear end to rise, the top of the contact 34 of open slot 32 both sides makes tapered end 55 break away from the lockhole of cage shell fragments the cage shell fragment jack-up that makes progress, outwards the pulling draw ring can be extracted module release in cage.
