Description

Extension plate shell structure and extension device

Technical Field

The invention relates to the technical field of optical module extension plates, in particular to an extension plate shell structure and an extension device.

Background

The optical module test equipment is used for testing the performance of an optical module, belongs to a precision instrument, and is connected with a golden finger (a connecting male head) of a pluggable optical module through a connector (a connecting female head) on a PCB of the optical module test equipment so as to test the pluggable optical module. However, since the connector of the optical module testing device has a certain service life and supports a certain number of plugging times, when the number of plugging times is exceeded, the signal quality is affected, and even the connector is completely inoperable, the connector of the optical module testing device needs to be replaced by returning to the factory, which is time-consuming and expensive, and the number of times of replacing the connector is very limited. Meanwhile, network equipment using the optical module also has similar problems, the pluggable frequency of a connector connected with the optical module is limited, and the connector is easily damaged due to frequent plugging of the optical module, so that the normal use of the whole network equipment is influenced.

In order to solve the problems, extension plates such as optical module test extension plates are adopted in the industry. The extension board is a PCB board and has two ends, one end is a male end (golden finger) connected with the extension board and is used for being connected with a connector (connecting female end) of optical module test equipment or a connector (connecting female end) of network equipment, and the other end is a female end connected with the extension board and is used for being connected with a male end (golden finger) connected with a pluggable optical module. Through the arrangement of the extension plate, the connection male head of the extension plate is always connected with a connector of optical module test equipment or a connector of network equipment, so that signals are extended, and optical modules which need to be plugged and unplugged frequently are directly connected with the connection female head of the extension plate. When the number of times of plugging and unplugging is exceeded by the female connection head of the extension board, the extension board is pulled out of the connector of the optical module testing equipment or the connector of the network equipment and replaced, so that the loss of the connector of the optical module testing equipment and the connector of the network equipment is avoided, and the testing cost and the maintenance cost are reduced.

However, the extension board in the prior art is usually a bare PCB, and has low structural strength, is easily bent and damaged by stress, and the extension board connection female head is exposed, so that when an optical module to be tested needs to be tested and is connected with the optical module test extension board connection female head, it is difficult to align and plug, and a small wing is required to align, which results in low efficiency, and is easy to be misaligned, affects the test precision, and is easy to accelerate the damage of the connection female head of the optical module test extension board. Therefore, the optical module is difficult to be inserted into the connection female head of the extension board quickly and accurately, which may result in serious consequences such as low test efficiency and large test error, and may also result in a problem of poor connection stability between the optical module and the network device.
