A small form-factor pluggable transceiver is coupled to a cable connector and a network device. The small form-factor pluggable transceiver includes a first connection port, a conversion unit, a transceiver unit, and a second connection port. The conversion unit includes a bandwidth indication pin, and the transceiver unit includes a detection pin. The transceiver unit operates in a normal state based on providing a first voltage level by the detection pin, and operates in an abnormal state based on providing the second voltage level by the detection pin. The bandwidth indication pin indicates that a signal source received by the first connection port is a copper cable-type signal source, and indicates that a rate of the signal source is an invalid rate. The detection pin provides the first voltage level based on the invalid rated by being coupled to a ground point.

An underwater robotic device includes a housing unit, a control unit and a propelling unit. The housing unit includes a base seat and an upper cover in liquid-tight engagement with the base seat. The control unit is disposed within the housing unit and includes a circuit module and a center-of-gravity transferring module which is electronically connected with the circuit module. The center-of-gravity transferring module has a movable weight member and a transfer driving mechanism which drives movement of the weight member so as to vary a position of a center of gravity of the underwater robotic device and to control downward and upward moving directions of the underwater robotic device in the water. The propelling unit is connected with the housing unit and is electronically connected with the control unit to produce a propelling force to move the underwater robotic device forward in the water.

An electrical connector and a cable grounding structure thereof are disclosed. A grounding structure is bridged between a connection body of the electrical connector and each cable, and includes a bridging portion, at least one clamping portion, at least one docking portion, and an elastic portion. The clamping portion is disposed on the bridging portion for clamping a covering layer of each cable, and the docking portion is extended from the bridging portion toward the connection body and electrically connected to connection body, and the elastic portion is attached and pressed against the covering layer of each cable, so as to provide good grounding contact and prevent the issue of skewing the cables and other factors that affects the soldering yield.

A circuit element protection apparatus applied to a signal input terminal, the circuit element protection apparatus includes a slave processing unit, a main processing unit, a first soft start unit and a second soft start unit. The first soft start unit receives a signal from the signal input terminal, and is used for noise filtering on the signal and delayed a transmission of the signal to the slave processing unit. The second soft start unit receives the signal from the signal input terminal, and is used for noise filtering on the signal and delayed the transmission of the signal to the main processing unit. The present disclosure further includes a protection method for circuit elements.

A coupling method of an optical module is provided. A circuit board with a light emitting element emitting an output light and an output lens are provided. The light emitting element is covered by the output lens. The output lens is connected to an output meter. The output lens and the circuit board are moved relatively. An intensity of the output light is measured by the output meter. An output qualified region is defined based on a region where the output lens is located when the intensity of the output light is greater than an output requirement. The aforementioned steps are repeated for a predetermined number of times. The output lens and the circuit board are moved relatively in an intersection area of the output qualified regions. The output lens is fixed on the circuit board when the intensity of the output light is greater than the output requirement.

A connector includes multiple ground terminals, multiple signal terminals, a cable and a ground assembly. The cable includes multiple ground wires and multiple signal wires. The ground assembly includes a plate and multiple protrusion structures. Each protrusion structure is arranged spacedly and extended from the plate. A top of each protrusion structure is higher than a surface of the plate. Each ground wire is electrically connected with each ground terminal and each protrusion structure. Each signal wire is electrically connected with each signal terminal. Each signal wire is formed between any two of the protrusion structures adjacent to each other. Therefore, high-speed transmission of digital signals may be undistortedly implemented.

Electrical connector

A cable connector includes a case, a fastener and an unlocking member. At least one side of the case has a texture area with a guide surface which is a smooth surface. The fastener is attached on the case and extended with a flexible arm. Part of the flexible arm is attached to the guide surface. The unlocking member includes a handle and a pushing block connected to the handle. The pushing block is sandwiched between the case and the flexible arm. When the unlocking member is pulled, the pushing block moves along the guide surface to separate the flexible arm from the case. When the unlocking member is released, the pushing block is pressed by the flexible arm to slide and return along the guide surface. The pushing block may return to original position without elasticity of a spring to simplify the structure and save the costs.
