SUMMERY OF THE UTILITY MODEL

The utility model aims to provide an SC optical module housing which is convenient to disassemble, so as to overcome the defects in the prior art.

The technical scheme for solving the technical problems is as follows: the utility model provides a SC optical module shell convenient to dismantle, includes two flip, column spinner and hasp nail, and two flip one end are passed through the column spinner and are rotated the connection, and accessible both sides hasp nail lock between two flip, and wherein a flip outside is the spill structure, and another flip outside is convex structure, is equipped with the hasp nail on convex structure's the flip.

The utility model has the beneficial effects that: two flip can rotate round the column spinner, under the effect of the hasp nail of both sides, with flip lock, fixed mode is simple, does not need use tools, and it is convenient to dismantle.

On the basis of the technical scheme, the utility model can be further improved as follows.

Furthermore, connecting holes are formed in the positions of the lock catch nails by the two turnover covers, nail caps of the lock catch nails are arranged outside the connecting holes, nail columns are movably arranged in the connecting holes, and the nail columns are horizontally arranged at the ends, far away from the top caps, of the nail columns.

Furthermore, the limiting ring is elliptical, and the length of the short shaft is larger than the diameter of the connecting hole.

Adopt above-mentioned further beneficial effect to do: the limiting ring is made of plastic and has certain elasticity, after the locking nail is inserted into the connecting hole, the nail post of the locking nail penetrates through the connecting hole, the end face of the other side of the nail post extends out of the connecting hole, and because the length of the short shaft of the limiting ring is greater than the diameter of the connecting hole, the limiting block ring can clamp the inner wall of the flip cover to fix the two flip covers; when the SC optical module shell is disassembled, the screw cap only needs to be pulled outwards, the limiting ring can be retracted inwards under the action of external force, the screw column slides in the connecting hole, and finally the screw column is pulled out, so that the connection is firm, and the disassembly is simple.

Further, two flip all seted up the transmission hole keeping away from column spinner one end.

Furthermore, a plurality of heat dissipation holes are formed in the surfaces of the two flip covers, and dust filter screens are bonded inside the heat dissipation holes.

Adopt above-mentioned further beneficial effect to do: prevent that the dust from getting into the circuit board from the louvre, prevent that the dust from piling up in the circuit board surface, lead to the heat can not in time spill, cause circuit board components and parts to burn out.

Furthermore, one of the two flip covers is adhered with a color card.

Adopt above-mentioned further beneficial effect to do: SC optical modules with different wavelengths can be rapidly distinguished through color cards on the shell, and subsequent inspection, maintenance and boxing are facilitated.

Furthermore, a ring groove is arranged on the top cap of the lock catch nail.

Adopt above-mentioned further beneficial effect to do: the ring groove is beneficial to the nail of the finger to fasten the nail cap, and the finger and the nail cap are prevented from slipping.

Detailed Description

The principles and features of this invention are described below in conjunction with the following drawings, which are set forth by way of illustration only and are not intended to limit the scope of the utility model.

Example 1

As shown in fig. 1 to 3, an SC optical module housing convenient to disassemble includes;

two flip 1, column spinner 2 and hasp nail 3, two 1 one ends of flip are passed through column spinner 2 and are rotated the connection, and accessible both sides hasp nail 3 lock between two flip 1, and wherein 1 outside of one flip is the spill structure, and 1 outside of another flip is the convex structure, is equipped with hasp nail 3 on the flip 1 of convex structure.

The flip cover 1 is made of elastic plastic, and when impact force is met, the influence of external acting force on a circuit board inside the SC optical module can be reduced.

Example 2

As shown in fig. 1 to fig. 3, this embodiment is a further improvement on embodiment 1, and is specifically as follows:

connecting holes 7 are formed in the positions of the locking nails 3 of the two turnover covers 1, the nail caps 310 of the locking nails 3 are arranged on the outer sides of the connecting holes 7, nail columns 320 are movably arranged in the connecting holes 7, and the limiting rings 3210 are horizontally formed in the ends, far away from the top caps 310, of the nail columns 320.
