## Abstract

A choke signal-adjusting device, and more particularly, a signal-adjusting device capable of increasing the high-frequency signal transmission quality, comprises a circuit board disposed in a connector, a plurality of transmission circuits being disposed on the circuit board, one side of the transmission circuit being taken as a signal input terminal, and another thereof being taken as an input terminal; it is characterized in that: a plurality of chokes are correspondingly disposed in series in the middle of the plurality of transmission circuits; whereby, the balance transmission signals of unequal time duration to signals of equal time duration so as to increase the signal transmission quality effectively.

## Claims

### Claim 1

A choke signal-adjusting device, capable of increasing the high-frequency signal transmission quality, said signal-adjusting device comprising a circuit board disposed in a connector, a plurality of transmission circuits being disposed on said circuit board, one side of said transmissions being a signal input terminal and another side thereof being a signal output terminal; wherein, a plurality of chokes are correspondingly disposed in series in the middle of said plurality of transmission circuits; whereby, balance transmission signals of unequal time duration are adjusted to signals of equal time duration to enable the signal transmission quality to be increased effectively.

### Claim 2 (depends on 1)

The choke signal-adjusting device according to claim 1, wherein the plurality of chokes adopt common chokes, said common choke is constituted by disposing two cross-coupling chokes in a housing and projection four pins used for respectively crossing over a reserved position of said two adjacent transmission circuits outside said housing.

### Claim 3 (depends on 2)

The choke signal-adjusting device according to claim 2, wherein said connector is a cable connector, said circuit board is buried inside said cable connector to allow an output terminal of said transmission circuit to be electrically connected to an output terminal of said connector and an input terminal on another side of said transmission circuit to be electrically connected to a cable.

### Claim 4 (depends on 2)

The choke signal-adjusting device according to claim 2, wherein said connector is a connector adapter, said circuit board is buried inside said connector adapter to allow an output terminal of said transmission circuit to be electrically connected to an output terminal of said connector adapter and an input terminal on another side of said transmission circuit to be electrically connected to an input terminal of said connector adapter.

### Claim 5 (depends on 3)

The choke signal-adjusting device according to claim 3, wherein said cable connector comprises said inbuilt circuit board, an outer cover made from a plastic material and at least one output terminal.

### Claim 6 (depends on 4)

The choke signal-adjusting device according to claim 4, wherein two ends of said connector adapter are respectively disposed with the same type of terminal.

### Claim 7 (depends on 4)

The choke signal-adjusting device according to claim 4, wherein two sides of said connector adapter are respectively disposed with different male and female terminals.
