Abstract: The present invention provides a car safety belt having a power source and communication wire, wherein the power source and communication wire is disposed on the car safety belt. One end of the power source and communication wire is connected to a first connector, while the other end thereof is connected to a second connector and/or a communication device like an earphone or a loudspeaker. In the present invention, the power source and communication wire is fixed on the safety belt so that the power source and communication wire can be well positioned and will not swing. Therefore, a user will not be disturbed when he is driving a car, hence effectively enhancing the driving safety.

Abstract: A fast combinational charger includes a shell body, a circuit unit, and a combinational module. The shell body has a bearing seat at the outer side. The circuit unit is disposed in the shell body, and has a first connector. The combinational module includes a module shell body and a module circuit board. The module circuit board is disposed in the module shell body. The module circuit board has terminals protruding out of the module shell body. The combinational module can be placed on the bearing seat. The module circuit board can be connected with the first connector to achieve electric connection with the circuit unit.

Abstract: A cable rewinding device comprises a rewinding box, a detector provided on a side of the rewinding box received in the rewinding box in a universal joint manner in a stored position having a ball member, a body including a detecting circuit having a circuit board, a plurality of lights, and a plurality of cords, and a head portion extended outwardly from the body having first spaced grooves and second spaced grooves, in which the cords are in an electrical communication with the first and the second spaced grooves such that an electrical status such as open circuit, error in connection, or over current of a cable having a plug is obtained through the lights when the plug is inserted into the first and the second spaced grooves. With this device, repairing in time, preventing error in connection, and avoiding damage to the electrical equipment are realized.

Abstract: A clamping structure for communication connector, wherein the connector has an insulating case, at least one coupling hole on the insulating case, a plurality of terminals with each the coupling hole, the end portion of the terminal exposing out of the insulating case. The clamping structure is characterized in that a plurality of clamping devices are arranged within the coupling hole and on the two bottom lateral sides of the coupling, the clamping means being supported within the coupling hole by elastic member. The inventive communication connector has clamping means with flexibility to firmly clamp the mating connector of various specifications. Therefore, the insulating case has broader applicability, thus reduces cost.
