A signal module and a signal relay device that can suppress the effect of noise are provided, and the signal module is a signal module of a tool changer including a first coupling member to be detachably attached to a body side of an industrial robot and a second coupling member to be detachably attached to a tool side, the signal module including a signal relay connector attached to the first coupling member or the second coupling member, and upon the first coupling member and the second coupling member being coupled, forming a signal path between the first coupling member side and the second coupling member side, wherein in the signal relay connector, a plurality of terminal pairs to be used for communication using differential signals are provided, and two terminals of each of the terminal pairs are arranged at mutually-adjacent positions.

In the process of mounting a joint terminal (5) into a first terminal accommodating portion (16) of a housing (15), tab terminals (6) of the joint terminal (5) move forward along tab entrance paths (26) formed in the housing (15). The tab entrance path (26) is formed with a cam portion (27) spiral about an axis thereof. As the tab terminal (6) moves forward in the tab entrance path (26), a follower portion (8) formed at an intermediate position of the tab terminal (6) is guided by the cam portion (27). Thus, the tab terminal (6) is twisted about an axis. In this way, resilient contact pieces (14) of female terminals (9A, 9B) face the tab terminals (6) in a plate surface direction of the tab terminals (6) and are connected to the tab terminals (6).

An Ethernet cable assembly including a cable with nine elongated conductors, a first connector and a second connector located on opposing ends of the cable, and a coupler for electrically coupling with one or both of the connectors. The connectors may each include nine pin receptacles electrically coupled with one of the elongated conductors. The nine receptacles may be arranged with one center receptacle surrounded by eight outer receptacles, symmetrically arranged about a line of symmetry passing through the center receptacle, such that when identical first or second connectors of another cable faces one of the first and second connectors, complementary crossover pairs of the receptacles match up with positive receptacles matching positive receptacles and negative receptacles matching negative receptacles. To couple these identical Ethernet connectors with each other, the coupler may have pins simply passing from one side of the coupler housing to another, without any crossover hardware required therein.

Electrical connector assemblies are provided that include electrical connectors having electrical contacts that have receptacle mating ends are provided. The connector housings of the provided electrical connectors include alignment members that are capable of performing staged alignment of components of the electrical connector assemblies. The provided electrical connector assemblies and the electrical connectors provided therein are capable of operating at a data transfer rate of forty gigabits per second with worst case multi-active cross talk that does not exceed a range of about two percent to about four percent.

A modular plug is disclosed for terminating a telecommunications cable having twisted pairs of wires. The modular plug includes a housing defining an internal cavity and slots positioned toward a distal end of the housing, each slot being parallel to a central axis of the modular plug, A wire manager is fitted inside the internal cavity, and defines channels for positioning the twisted pairs of wires inside the housing. A wire sled extends from the wire manager and defines a plurality of grooves, each groove shaped to position an individual wire from the twisted pairs of wires at an angle with respect to the central axis. The modular plug further includes a plurality of plug contacts. Each plug contact is held by a slot of the housing and is structured to form an electrical interface with a wire positioned by the wire sled.
