A terminal module includes a number of conductive terminals. Each conductive terminal includes a contact portion. The conductive terminals include differential signal terminals. Each differential signal terminal includes a first extending portion, a torsion portion, and a second extending portion perpendicular to the first extending portion. The differential signal terminals include a first signal terminal and a second signal terminal. Most of the two first extending portions of the differential signal terminals are narrow-side coupled, and small parts are wide-side coupled. The second extending portions of the differential signal terminals are narrow-sided coupled. The present disclosure also discloses a backplane connector having the terminal module. Compared with the prior art, the present disclosure can make the differential signal terminals tightly coupled, thereby stabilizing the insertion loss.

A clamp for a male terminal having features for preventing incorrect clamping, which comprises a main body having a ring and two jaws, that are movable toward each other for the ring to hold the terminal. An engagement element is movable in the vertical direction and to act upon the jaws to move them toward each other. A clamping member, operable to move the engagement element comprises a stem and a nut. The stem is fixed to a base body, which is pivotable relative to the main body between a first position, in which the stem is inclined with respect to the vertical and a second position, in which the stem extends in the vertical direction. In the first position, the engagement element prevents the nut from engaging a threaded portion of the stem. In the second position, the threaded portion is adapted to be engaged by the nut.

A grounding system, structured to ground a number of cables supported by a support assembly, includes a multi-function line assembly and a number of conductive mounting assemblies. Each conductive mounting assembly is structured to be coupled to the multi-function line and to a conductive pile.

A meter box ground clamp may include a body portion having a first portion, a second portion, and a gripping portion that is configured to extend from the second portion and a fastener member configured to couple the body portion to an electrical meter box. The fastening member may be configured to extend through a receiving portion of the first portion to engage a first surface of the meter box so as to move the first portion away from the first surface of the meter box and move the gripping portion into engagement with a second surface of the meter box that faces away from the first surface of the meter box, and the receiving portion may be configured to receive the fastener member at a first angle less than 90 degrees relative to a plane of the first portion such that a free end of the fastener member forms a second angle greater than zero degrees relative to the second surface of the meter box. The second angle may be configured to create a force that urges the second portion of the body portion toward the meter box in response to a tightening torque applied to the fastener member so as to prevent the body portion from moving off the meter box in response to the tightening torque.

A contact assembly includes a contact element having a lead-through opening, a contact section extending in a tube-shaped manner along the lead-through opening and having a contact surface, and a collar section connected to the contact section and extending the lead-through opening in a sleeve-shaped manner, a busbar having a reception opening receiving the collar section, and a fastener inserted into the lead-through opening. The contact element has a first friction surface affixable with the busbar in the reception opening in a frictionally engaging manner and a second friction surface affixable in the reception opening with the busbar or in the lead-through opening with the fastener in a frictionally engaging manner. The first friction surface and the second friction surface are mutually offset in a radial direction with respect to the lead-through opening.

A battery terminal includes a terminal main body and a protector to be mounted to the terminal main body, wherein the terminal main body includes an operating section for clamping and tightening the battery post, and the protector includes a movable section provided with a contact section to be brought into contact with the upper surface of the battery main body, and a displacement section to be freely displaced between a covering position for covering the operating section and a retracted position with an external force applied on the contact section, wherein in the retracted position, the displacement section is retracted from the covering position, and wherein the displacement section is displaced to the retracted position by pressing the contact section against the upper surface of the battery main body so that the access to the operating section is allowed.
