Abstract

The present invention relates to an electrical connector (100) for a twisted-pair cable using resin solder, comprising: a pair of electrical contacts (110), (110), having a second connecting portion (112) connected to the opposite side The first connection part (111) and the conductor (210) of the electric wire (200) are fitted together; and the insulating member (120), which insulates and insulates these electrical contacts (110), (110) Keep. In each electrical contact piece (110), at least the conductor (210) part used to connect the wire (200) in the second connection part (112) is made of a conductive resin composition composed of lead free and ultra-high conductivity. Plastic is formed. The purpose of the present invention is to connect the twisted-pair cable to the electrical connector without untwisting the twisted end, ensure the correct twisting of the twisted-pair cable to the end, and make the twisted-pair cable cancel out the clutter signal. to the maximum for maximum impedance integration.

Description

[Background of the invention] [0001] The present invention belongs to the technical field of electrical connectors to which twisted-pair cables are connected. The electrical connector is provided with an electrical contact using lead-free ultra-high conductivity plastic composed of a conductive resin composition. 【Background technique】 [0002] As a signal wire that transmits electrical signals, it is known that two wires are twisted to form a twisted pair cable. Even if a clutter current is generated in the twisted pair cable by the external magnetic flux, the clutter current is canceled out. Therefore, the twisted pair cable is difficult to be affected by the clutter by the external inductive coupling. Furthermore, due to the interference effect of the clutter signal, the signal of the twisted pair cable is difficult to be affected by the signal of other twisted pairs of cables, so that the crosstalk has improved characteristics compared with the normal twisted pair cable.
