Description

Technical Field

[0001] The present invention relates to the technical field of optical fiber communication, and in particular to an optical module shell removal structure. Background Art

[0002] The optical module generally needs to be designed with a movable shell ejection structure so that the optical module can be locked by the buckle when inserted into the chassis 10a for use to prevent it from loosening and avoid signal interruption, but it can also be easily pulled out of the chassis 10a when it needs to be taken out.

[0003] At present, many optical module shell removal structures are as follows: Figure 1 As shown, it includes a handle body 1a and a pull ring 2a, the handle body 1a is H-shaped, and the pull ring 2a is U-shaped or C-shaped; the handle body 1a includes two parallel vertical rods 3a and a horizontal rod 4a for connecting the two vertical rods 3a, one end of the two vertical rods 3a are respectively movably connected to the two sides of the shell 9a of the optical module, and the other end is respectively connected to the two ends of the pull ring 2a; the shell 9a of the optical module generally includes an upper cover 5a and a base 6a, after assembly, the upper cover 5a and the base 6a of the shell 9a can limit the upper and lower positions of the handle body 1a, but the front and rear positions can be movable, and the connection structure of the upper cover 5a, the base 6a and the handle body 1a is the prior art; the handle body 1a is generally made of a relatively high-strength metal material, so that when pulled back, the two vertical rods can push open the elastic buckle on the shell 9a of the optical module to achieve the purpose of shell removal; the pull ring 2a is generally made of a flexible plastic material, which is convenient for hand pulling; the handle body 1a and the pull ring 2a are generally combined together through a plastic coating process. As shown Figure 2 , which is a schematic diagram of the structure in which the optical module shell removal structure is installed in the upper cover 5a and the base 6a of the housing 9a of the optical module.

[0004] like Figure 3 As shown, it is a structural schematic diagram of the optical module shell withdrawal structure and the optical module installed on the chassis 10a after being fully assembled. From the figure, we can see that a section of the optical module will be exposed outside the chassis 10a. At present, the transmission rate of the optical module is constantly increasing, and the corresponding power consumption is also getting higher and higher, resulting in a large amount of heat generated by the optical module during operation. In addition, the shell 9a of the optical module is generally made of metal material, so that the part 7a of the optical module exposed outside the chassis 10a will be very hot. When the operator is plugging in or out the optical connector 8a of the optical module, if the hand accidentally touches these high-temperature parts, it is easy to be burned. Summary of the invention

[0005] The technical problem to be solved by the present invention is to provide an optical module shell removal structure with a heat insulation effect and capable of preventing high temperature burns.

[0006] The technical solution of the present invention is: an optical module shell ejection structure, including a handle body and a pull ring, the handle body including two vertical rods parallel to each other, the pull ring is U-shaped or C-shaped, one end of the two vertical rods are respectively movably connected to the two sides of the shell of the optical module front and back, and the other end is respectively connected to the two ends of the pull ring, characterized in that: a first U-shaped seat with an opening facing upward is provided between the two vertical rods and on the side close to the pull ring, and a second U-shaped seat with an opening facing downward is provided between the two ends of the pull ring, one end of the two vertical rods close to the pull ring is connected with the second U-shaped seat through the first U-shaped seat and the second U-shaped seat connected up and down, and the four surfaces formed by the first U-shaped seat and the second U-shaped seat being connected are covered on the four sides of the optical module exposed outside the chassis, the handle body is made of hard material, and the first U-shaped seat and the second U-shaped seat are made of insulating material.

[0007] After adopting the above structure, the present invention has the following advantages:

[0008] The optical module shell ejection structure of the present invention is provided with a first U-shaped seat and a second U-shaped seat made of insulating material which are butted up and down at the connection between the handle body and the pull ring. The four insulating surfaces formed by the upper and lower butt joints of the first U-shaped seat and the second U-shaped seat are used to cover the four side surfaces of the optical module exposed outside the chassis. That is, the optical module shell ejection structure has an insulating effect on the portion of the optical module exposed outside the chassis, so that when the operator plugs in and out the optical connector of the optical module, the operator will not directly contact the portion of the optical module exposed outside the chassis, thereby preventing high-temperature burns.

[0009] Preferably, the first U-shaped seat is detachably connected to the second U-shaped seat. This arrangement can facilitate the assembly of the optical module shell-retracting structure and the optical module, as well as the manufacturing of parts of the optical module shell-retracting structure.

The first U-shaped seat made of a hard material can ensure the stability of the structure, and the second U-shaped seat made of a flexible material, as well as the positioning protrusion and the positioning hole, can make the detachable connection structure simpler and more convenient to assemble.

[0011] Preferably, the pull ring is made of a flexible material. This arrangement makes it convenient to pull the pull ring by hand.
