Description

Technical Field

[0001] The present invention relates to an optical module, and in particular to a high-speed optical module shielding structure. Background Art

[0002] Electromagnetic shielding is a measure used to reduce the field strength caused by certain sources within a certain area of ​​space. In most cases, the shield can be made of metals such as copper, aluminum, or steel. However, for constant and extremely low-frequency magnetic fields, materials such as ferrite can also be used as a shield. The optical module's housing is constructed by splicing the upper and lower parts together, with conductive rubber sandwiched between the gaps in the housing to form a complete conductive loop, thus achieving the shielding function. However, the existing conductive rubber is not fixed during installation, making it easy to shift or fall off, increasing the difficulty of installation. Summary of the Invention

When the upper shell is located on top of the lower shell, the first conductive rubber contacts the second metal strip.

[0005] The beneficial effects of the present invention are as follows: when the upper shell cover is arranged on the top of the lower shell, the first conductive rubber is arranged on the first metal strip through the positioning strip; when the upper shell cover is arranged on the lower shell, the first conductive rubber does not move, which facilitates the operation of the first conductive rubber during installation; and the second metal strip contacts the first conductive rubber, so that the upper shell and the lower shell form a complete conductive circuit.

DETAILED DESCRIPTION

[0010] The principles and features of the present invention are described below with reference to the accompanying drawings. The embodiments given are only used to explain the present invention and are not used to limit the scope of the present invention.

[0011] like Figure 1-3 As shown, embodiment 1 of the present invention provides a high-speed optical module shielding structure, including a lower shell 1 and an upper shell 2, wherein a first metal strip 3 is provided on both sides of the bottom of the upper shell 2, and a second metal strip 4 parallel to the upper shell 2 is provided on both side walls of the lower shell 1, and positioning strips 6 are provided on both sides of the bottom of the first metal strip 3, and a first conductive rubber 5 is provided inside the positioning strip 6. When the upper shell 2 is located on top of the lower shell 1, the first conductive rubber 5 is in contact with the second metal strip 4.

[0012] When the upper shell 2 is placed on top of the lower shell 1, the first conductive rubber 5 is arranged on the first metal strip 3 via the positioning strip 6. When the upper shell 2 is placed on the lower shell 1, the first conductive rubber 5 does not move, which facilitates the operation of the first conductive rubber 5 during installation. The second metal strip 4 contacts the first conductive rubber 5, forming a complete conductive circuit between the upper shell 2 and the lower shell 1.

[0013] Embodiment 2 of the present invention provides a high-speed optical module shielding structure. Based on embodiment 1, it further includes a second conductive rubber 8 and an elastic component 9 arranged on both sides of the bottom of the upper shell 2. The interiors of the two first metal strips 3 are parallel to the upper shell 2 and a through hole 7 is opened. The second conductive rubber 8 is located inside the through hole 7 and contacts the inner wall of the through hole 7. The second conductive rubber 8 is elastically contacted with the first conductive rubber 5 through the elastic component 9. When the upper shell 2 is covered on the top of the lower shell 1, the first conductive rubber 5 is squeezed into an L shape by the first metal strip 3. The horizontal end of the L-shaped first conductive rubber 5 contacts the second metal strip 4. The second conductive rubber 8 is elastically pushed by the elastic component 9 so that the vertical end of the L-shaped first conductive rubber 5 contacts the side wall of the lower shell 1, avoiding a gap at the connection between the lower shell 1 and the upper shell 2, thereby improving the shielding effect of the lower shell 1 and the upper shell 2.

[0014] Embodiment 3 of the present invention provides a high-speed optical module shielding structure. Based on Embodiment 2, the elastic component 9 includes a pushing plate 91 and a fixing plate 93. The pushing plate 91 is arranged at one end of the second conductive rubber 8 away from the first conductive rubber 5. The fixing plate 93 is arranged perpendicular to the second conductive rubber 8 at the bottom of the upper shell 2. A spring 92 is provided between the pushing plate 91 and the fixing plate 93. The spring 92 is arranged between the pushing plate 91 and the fixing plate 93. When the upper shell 2 is covered on top of the lower shell 1, the spring 92 pushes the second conductive rubber 8 to contact the first conductive rubber 5, so that the first conductive rubber 5 is in elastic contact with the inner wall of the lower shell 1, ensuring that the first conductive rubber 5 is in contact with the side wall of the lower shell 1.

[0015] Example 4 of the present invention provides a high-speed optical module shielding structure. Based on Example 3, the elastic component 9 also includes two positioning rods 94. The two ends of the push plate 91 are respectively connected to the push plate 91 and the fixed plate 93 through the two positioning rods 94. The positioning rod 94 is arranged inside the spring 92 to improve the stability of the spring 92 on the fixed plate 93 and the push plate 91.

[0016] Embodiment 5 of the present invention provides a high-speed optical module shielding structure. Based on Embodiment 4, the side wall of the first metal strip 3 near the lower housing 1 is rounded. When the first metal strip 3 squeezes the first conductive rubber 5, the sharp corners of the first conductive rubber 5 are prevented from causing the first conductive rubber 5 to break, thereby improving the protection of the first conductive rubber 5 and extending the service life of the first conductive rubber 5.

[0017] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
