A cable connection device is provided. The cable connection device includes a casing, a connection component, a power cable and a circuit board. The casing includes a first accommodation space, a second accommodation space and a channel. The channel is in communication between the first accommodation space and the second accommodation space. The connection component is penetrated through the channel and includes a clamping part disposed in the first accommodation space and a first conductive part disposed in the second accommodation space. Portion of the power cable is disposed in the first accommodation space. The clamping part clamps the power cable and partially pierces the insulating sleeve, so that the clamping part is connected with the wire core. The circuit board is disposed in the second accommodation space and comprises second conductive part. The second conductive part is contacted with the first conductive part.

A wire-clamping connector assembly includes a wire-clamping connector and a mating connector that are mated with each other. The wire-clamping connector includes a casing and a conductive cable. The casing includes a first wire-fixing portion, a second wire-fixing portion, and a third wire-fixing portion that is located therebetween. A first gap is formed between the first wire-fixing portion and the third wire-fixing portion, and a second gap is formed between the second wire-fixing portion and the third wire-fixing portion. The conductive cable includes a conductive cable body and insulating bodies that cover the conductive cable body. The conductive cable passes through the first gap and the second gap, such that a third extension section is surroundingly arranged below the third wire-fixing portion. An extension direction of the conductive cable is perpendicular to a mating direction of the mating connector and the wire-clamping connector.
