Problems solved by technology
There are few conductive connection points between the metal package base and the upper cover of the high-speed optical transceiver module, which is particularly prone to electromagnetic interference EMI, which causes other electronic components to fail to operate normally
Especially when the rate of the optical transceiver module increases, its physical configuration is poor in suppressing EMI, which will greatly affect the electromagnetic shielding effect of the entire optical module

Embodiment Construction
[0018] The preferred embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings.
[0019] Such as figure 1 The optical transceiver module shown includes: a base 100 , an upper cover 200A and a PCB circuit board 300 . Such as figure 2 The upper cover 200A shown has a plurality of outwardly extending elastic teeth 240A on its two sides 210A, 220A and a front end 250A, and a plurality of downward in-line conductive posts 270A on the rear end 260A. Such as image 3 and Figure 4 As shown, when the upper cover 200A is fixed to the base 100, the elastic tooth piece 240A is pressed into the base 100, and the elastic tooth piece will contact both sides and the inner wall of the front end to form a plurality of conductive connection points, and the in-line conductive column 270A The ends pass through the PCB circuit board 300 from top to bottom and contact the bottom surface of the base 100 to form a plurality of conductive ...

The invention provides a light receiving and transmitting module. The light receiving and transmitting module comprises a base, an upper cover and a PCB; a plurality of elastic tooth blades are arranged at two sides of the upper cover and form a plurality of conductive connecting points at two sides of the base; the plurality of elastic tooth blades are arranged at the front end of the upper cover and in contact with the front end of the base to form the plurality of conductive connecting points. According to the light receiving and transmitting module adopting the structure above, the plurality of elastic teeth are arranged at two sides and the front end of the upper cover, a direct inserting type conducting column is arranged at the rear end of the upper cover or the bottom part of the base to pass through the PCB, the conductive connecting points are further added between the upper cover and the base, or a plurality of conductive columns are respectively arranged on the upper surface and the lower surface of the PCB to form a plurality of conductive connecting points with the upper cover and the base, and the measures above can improve the electromagnetic shielding effect of the whole light and transmitting module.
Description
technical field [0001] The invention relates to a metal-encapsulated optical transceiver module. Background technique [0002] As the transmission rate of metal-encapsulated optical transceiver modules increases, electromagnetic interference (EMI, hereinafter referred to as EMI) is involved more and more. EMI is the electromagnetic noise generated by the optical transceiver module, which emits electromagnetic waves. There are few conductive connection points between the metal package base and the upper cover of the high-speed optical transceiver module, which is particularly prone to electromagnetic interference EMI, which causes other electronic components to fail to operate normally. Especially when the rate of the optical transceiver module increases, its physical configuration is poor in suppressing EMI, which will greatly affect the electromagnetic shielding effect of the entire optical module. Contents of the invention [0003] In order to overcome the above disadv...
