Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0028] The core of the present invention is to provide a modular connection device for a multi-channel optical port sampling oscilloscope, and its structure is relatively compact.

[0029] For the specific first embodiment of the modular connection device for the multi-channel optical port sampling oscilloscope provided by the present invention, please refer to Figure 1 , including a sample and hold module and an optoelectronic converter module.

[0030] The sample and hold module includes a sample and hold function base plate 5 and several sub-sample and hold function circuit boards 12. Each sub-sample and hold function circuit board 12 is respectively connected to the sample and hold function base plate 5 through a holder connector. Among them, each sub-sample and hold function circuit board 12 is an independent circuit function board, realizing the function of signal sampling and holding.

[0031] The optoelectronic converter module includes an optoelectronic converter function base plate 6 and several sub-optoelectronic converter function circuit boards 42. Each sub-optoelectronic converter function circuit board 42 is respectively connected to the optoelectronic converter function base plate 6 through a converter connector. Among them, each sub-optoelectronic converter function circuit board 42 is an independent circuit function board, realizing the conversion of optoelectronic signals.

[0032] Each sub-optoelectronic converter function circuit board 42 is respectively communicatively connected to the corresponding sub-sample and hold function circuit board 12.

[0033] In this embodiment, four sub-sample and hold function circuit boards 12 and four sub-optoelectronic converter function circuit boards 42 are provided. In other embodiments, the sub-sample and hold function circuit boards 12 and the sub-optoelectronic converter function circuit boards 42 can also be provided with other numbers, such as two.

[0034] The sample and hold function base plate 5 is provided with a communication structure and a power supply structure. The sample and hold function base plate 5 is used to supply power to the sub-sample and hold function circuit boards 12 and for communication between the sub-sample and hold function circuit boards 12 and other external devices. The optoelectronic converter function base plate 6 is also provided with a communication structure and a power supply structure. The optoelectronic converter function base plate 6 is used to supply power to the sub-optoelectronic converter function circuit boards 42 and for communication between the sub-optoelectronic converter function circuit boards 42 and other external devices.

[0035] The multi-channel optical port sampling oscilloscope modular connection device in this embodiment has a modular structure of a sample-and-hold module and an optoelectronic converter module. By selecting different models of sub-sample-and-hold functional circuit boards 12 and sub-optoelectronic converter functional circuit boards 42, the model setting requirements of the sample-and-hold and optoelectronic converter can be met. At the same time, each sub-sample-and-hold functional circuit board 12 is connected to the same sample-and-hold functional base plate 5, and each sub-optoelectronic converter functional circuit board 42 is connected to the same optoelectronic converter functional base plate 6. The functional base plate can be used as a substrate for assembling the corresponding circuit boards, which provides convenience for installation. Moreover, the circuit boards can be powered through the corresponding functional base plates, eliminating the need to set up a power supply module for each circuit board separately, which helps to make the device structure compact.

[0036] In addition, each sub-optoelectronic converter functional circuit board 42 is respectively provided with a converter output differential male socket 43, and each sub-sample-and-hold functional circuit board 12 is respectively provided with a sample-and-hold output differential male socket 13. The converter output differential male socket 43 is connected to the corresponding sample-and-hold output differential male socket 13 through a radio frequency hard rod 2 to achieve the corresponding connection between the sub-optoelectronic converter functional circuit board 42 and the sub-sample-and-hold functional circuit board 12. Specifically, the radio frequency hard rod 2 is specifically a radio frequency connector double female type connecting rod.

[0037] Using the radio frequency hard rod 2 to achieve direct connection between the sub-sample-and-hold functional circuit board 12 and the sub-optoelectronic converter functional circuit board 42 does not require radio frequency cables, which can make more full use of the structural space, eliminate the use of radio frequency cables, make the radio frequency path as short as possible, and reduce the attenuation of signals on the path; moreover, the rigid radio frequency hard rod 2 has a certain positioning effect on the sub-sample-and-hold functional circuit board 12 and the sub-optoelectronic converter functional circuit board 42.

[0038] Furthermore, each sub-sample-and-hold functional circuit board 12 is arranged in sequence along a preset straight line direction to form a sample-and-hold functional circuit board 1, and each sub-optoelectronic converter functional circuit board 42 is arranged in sequence along the preset straight line direction to form an optoelectronic converter functional circuit board 4. The number of sub-sample-and-hold functional circuit boards 12 is the same as that of sub-optoelectronic converter functional circuit boards 42, and the sub-sample-and-hold functional circuit boards 12 and the sub-optoelectronic converter functional circuit boards 42 are connected in one-to-one correspondence. Specifically, the preset straight line direction can be perpendicular to the up-and-down direction, specifically the X direction in the figure, and the sample-and-hold functional circuit board 1 and the optoelectronic converter functional circuit board 4 are arranged in sequence along the Y direction, where the X direction, the Y direction, and the up-and-down direction are perpendicular to each other in pairs.

[0039] In this embodiment, through the linear arrangement of the sub-sampling hold function circuit board 12 and the sub-optical-electric converter function circuit board 42, the structure is simple, and it is convenient to determine the positions of the paired sub-sampling hold function circuit board 12 and sub-optical-electric converter function circuit board 42 and assemble them. Of course, in other embodiments, the sub-sampling hold function circuit boards 12 in the sampling hold module can be arranged in a matrix, and the sub-optical-electric converter function circuit boards 42 in the optical-electric converter module can also be arranged in a matrix.

[0040] Further, the hold connector includes a hold floating female plug 11 fixed to the bottom surface of the sub-sampling hold function circuit board 12, and a hold floating male socket 51 fixed to the top surface of the sampling hold function base plate 5. The hold floating female plug 11 and the hold floating male socket 51 are plugged and connected in the up-down direction, and there is an activity space between the hold floating female plug 11 and the hold floating male socket 51 in a direction perpendicular to the up-down direction. As Figure 1 shown, after the hold floating female plug 11 and the hold floating male socket 51 are connected, there is a certain activity space in the X direction and the Y direction, and specifically, it can float within a range of 0.6 mm in the X direction and the Y direction.

[0041] In this embodiment, since the sub-sampling hold function circuit board 12 and the sampling hold function base plate 5 are connected in a floating manner by means of the hold floating female plug 11 and the hold floating male socket 51, the installation between the sub-sampling hold function circuit board 12 and the sampling hold function base plate 5 can withstand a certain structural deviation. In addition, by using a plug-socket connection, the sub-sampling hold function circuit board 12 can be flexibly replaced.

[0042] Of course, in other embodiments, the hold floating female plug 11 can also be arranged on the top surface of the sampling hold function base plate 5, and the hold floating male socket 51 can be arranged on the bottom surface of the sub-sampling hold function circuit board 12.

[0043] Further, the converter connector includes a converter floating female plug 41 fixed to the bottom surface of the sub-optical-electric converter function circuit board 42, and a converter floating male socket 61 fixed to the top surface of the optical-electric converter function base plate 6. The converter floating female plug 41 and the converter floating male socket 61 are plugged and connected in the up-down direction, and there is an activity space between the converter floating female plug 41 and the converter floating male socket 61 in a direction perpendicular to the up-down direction. As Figure 1 shown, after the converter floating female plug 41 and the converter floating male socket 61 are connected, there is a certain activity space in the X direction and the Y direction, and specifically, it can float within a range of 0.6 mm in the X direction and the Y direction.

[0044] In this embodiment, since the sub-optical-electric converter functional circuit board 42 and the optical-electric converter functional base plate 6 are floatingly connected by means of the converter floating female plug 41 and the converter floating male socket 61, the installation between the sub-optical-electric converter functional circuit board 42 and the optical-electric converter functional base plate 6 can withstand a certain structural deviation, and the installation is more flexible and reliable. In addition, by using the plug and socket connection, the sub-optical-electric converter functional circuit board 42 can be flexibly replaced.

[0045] Of course, in other embodiments, the converter floating female plug 41 can also be arranged on the top surface of the optical-electric converter functional base plate 6, and the converter floating male socket 61 can be arranged on the bottom surface of the sub-optical-electric converter functional circuit board 42.

[0046] Further, the holder output differential male socket 13 is arranged on the top surface of the sub-sample-and-hold functional circuit board 12, and the converter output differential male socket 43 is arranged on the top surface of the sub-optical-electric converter functional circuit board 42, which is convenient for the connection operation.

[0047] Further, the multi-channel optical port sampling oscilloscope modular connection device further includes a heat dissipation bracket 3. The sample-and-hold module and the optical-electric converter module are both attached to the heat dissipation bracket 3, which can realize the installation and fixation and heat dissipation of the sample-and-hold module and the optical-electric converter module. Specifically, the heat dissipation bracket 3 is a metal bracket.

[0048] Further, the sample-and-hold functional base plate 5 and the optical-electric converter functional base plate 6 are respectively attached to the top surface of the heat dissipation bracket 3. During assembly, after the sample-and-hold functional base plate 5 and the optical-electric converter functional base plate 6 are attached to the top surface of the heat dissipation bracket 3, the sub-sample-and-hold functional circuit board 12 and the sub-optical-electric converter functional circuit board 42 can be correspondingly installed above the sample-and-hold functional base plate 5 and the optical-electric converter functional base plate 6. Compared with the sub-sample-and-hold functional circuit board 12 and the sub-optical-electric converter functional circuit board 42 being attached to the heat dissipation bracket 3 one by one, it is convenient for assembly.

[0049] The multi-channel optical port sampling oscilloscope modular connection device in this embodiment is used for being arranged at the optical-electric conversion front end in the multi-channel optical sampling oscilloscope. It has a compact structure, eliminates the use of RF cables, makes more full use of the structural space, and occupies less space. With a standard modular design and the application of floating connectors, it can conveniently adapt to different rate requirements by replacing components.
