Fill the 4th groove 114 of the forearm 224.First groove 111 of the present embodiment, the second groove 112, third groove 113 and
4th groove 114 is matched with corresponding structure on slider 22.
Further, the intermediate arm 223 is equipped with limiting slot 225, and the third groove 113 is equipped with limited block 115,
The limited block 115 is arranged in the limiting slot 225, so that intermediate arm 223 is restricted when sliding back and forth with slider 22,
It will not slip over.
Further, the two sides up and down of the intermediate arm 223 are equipped with limiting slot 225, the third groove 113 it is upper
Lower two sides are corresponding to be set to limited block 115.
Further, the length of the limiting slot 225 is greater than the length of the limited block 115, second groove 112
Length be greater than the length of the postbrachium 222 so that limiting slot 225 and limited block 115 can make to slide while limit
Locking and unlocking function is realized in the sliding of movable plate 22.
The intermediate arm 223 of the pull ring 2 of optical module shell mechanism provided in this embodiment is equipped with limiting slot 225, corresponding
The third groove 113 of shell 1 is equipped with the limited block 115 being stuck in limiting slot 225, can limit 2 sliding scale of pull ring, so that
When front and back pulls pull ring 2, pull ring 2 can only slide back and forth the determining distance of design in 1 two sides of shell, to guarantee to realize pull ring
Unlocking function, and accuracy is high.In addition, the presence of limiting slot 225 and limited block 115, so that the intermediate width of pull ring 2 becomes
It is narrow, pull ring 2 and the not linear gap in about 2 two sides of shell, so that the optical module shell mechanism has good electricity
Shielding ability.
Further, the top surface, bottom surface of the slider 22 and the slider 22 are close to the one of the mounting groove 11
Face has the gap 3 between the mounting groove 11.Due to when optical module shell, which is inserted in, to work in device mask cage, optical module front end
Be an exposure to equipment installation cage 4 outside, the mounting groove due to pull ring 2 to be guaranteed in 1 two sides of shell slide back and forth it is smooth, so
11 inside of mounting groove of pull ring 2 and shell 1 and survey up and down can there are gaps 3.
And the gap 3 inevitably results in EMI leakage, the present embodiment, then can be with by the way that 2 middle part bit width of pull ring narrows
So that pull ring 2 becomes smaller with 1 inside gap width of shell, to reduce EMI leakage, while the gap 3 of pull ring upper and lower sides is in pull ring 2
It narrows position and forms two 90 degree of turnings, so that the gap becomes the gap 3 of non-linear shape, so as to hinder EMI leakage.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, and 3 is all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
