Description
Technical Field
The utility model relates to a technical field of USB module, in particular to USB module with filtering function.
Background
When testing radio frequency products such as mobile phones, computers, wireless routers and the like, a shielding box is needed for testing, and the shielding box needs to be provided with a corresponding radio frequency interface. With the continuous update of wireless communication technology, the product performance is better and better, and the test requirement and the anti-interference capability are higher and higher, which provides higher requirements for the test. Therefore, the USB module with the filtering function is provided, so that the USB module can play a role in connection and can shield unnecessary signals.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that overcome prior art not enough, provide a simple structure, reasonable in design and better USB module with filtering capability of shielding property.
The utility model adopts the technical proposal that: the utility model discloses an installation casing, be provided with first USB adapter and second USB adapter on the installation casing, first USB adapter with all be provided with fiber communication module on the second USB adapter, first USB adapter with the second USB adapter passes through fiber communication module signal connection, the positive pole of first USB adapter pass through anodal electric wire with the positive pole of second USB adapter is connected, the negative pole of first USB adapter pass through the negative pole electric wire with the negative pole of second USB adapter is connected, anodal electric wire with all be connected with punching electric capacity on the negative pole electric wire.
Further, an electroplated layer is arranged on the mounting shell.
Furthermore, a shell cover is detachably arranged on the installation shell.
The utility model has the advantages that: when the USB adapter is powered on to work, the first USB adapter and the second USB adapter convert electrical signals into optical signals through the two groups of optical fiber transceiving modules for transmission, then convert the optical signals into electrical signals to achieve the purpose of communication, and feedthrough capacitors are arranged on the connecting wires of the positive electrodes and the negative electrodes of the first USB adapter and the second USB adapter to eliminate high-frequency coupling, block high-frequency and low-frequency passing and ensure filtering performance; it can be seen that, the utility model has the advantages of simple overall structure, reasonable in design still has better shielding property simultaneously, has both realized USB's connection function, still has the effect of wave filter concurrently.
