A system includes a pair of terminal leads joined together. An insulative sleeve is wrapped around the pair of terminal leads. Lacing binds around the insulative sleeve. Cured epoxy can encase the insulative sleeve and lacing. The insulative sleeve can include fiberglass. The insulative sleeve can be wrapped more than 360° around the pair of terminal leads so that a first edge of the insulative sleeve is tucked under a second edge of the insulative sleeve.

An electrical assembly includes a terminal block including a conductive bar having a connection end extending within a receiving recess of the terminal block, a pluggable connector releasably mounted on the terminal block, and a conductor adapter having a receptacle cooperating with the connection end in the mounted position. The connection end of the conductive bar extends in an insertion direction of the pluggable connector in a mounted position within the receiving recess. The pluggable connector has a central through-opening receiving and removably clipping the conductor adapter.

A tool-less terminal block includes an insulated base, a turning part, a conductive terminal, and a spring clamp. The insulated base has a cavity and a slot communicating to the cavity; the turning part is pivotally coupled to the insulated base; the conductive terminal is fixed to the bottom of the slot; the spring clamp is accommodated in the cavity and disposed at the top of the conductive terminal, and the spring clamp has a movable elastic arm pressing the conductive terminal to seal the slot, and the movable elastic arm has a link rod fixed to the turning part and operable together with the turning part. When the turning part is turned to a released position, the link rod is pulled by the turning part to drive the movable elastic arm away from the conductive terminal to open the slot, so as to provide a convenient use.

There is provided an electric connection part including: a nut made of a metal, the nut being used for fixing a conductor; and a housing made of a resin, the housing having a press-fit groove into which the nut is press-fitted. The housing includes: a rib that protrudes from an inner side surface of the press-fit groove and extends along a press-fitting direction in which the nut is press-fitted into the press-fit groove, such that the rib presses the nut to be in contact with the nut; and a recess that is disposed on an extension line in which the rib extends, the recess being recessed in the press-fitting direction.

Disclosed is a train coupler connector module for electrically coupling a first rail vehicle to a second rail vehicle, the module including: a fixing block with an inner side able to be mounted on an electrical train coupler; a plurality of contact units arranged side by side in the fixing block, each contact unit having a first end facing the inner side of the fixing block and a second end extending outwards from the fixing block, one of the first and second end being a female contact and the other being a male contact; wherein at least one of the contact units is arranged to be individually removable from the fixing block in a direction outwards from the fixing block.

An electrical connection component includes a conductor, and a housing into which the conductor is press-fitted. The housing includes a press-fitted portion having a hollow shape and into which the conductor is press-fitted in a press-fitting direction, and a restriction portion provided at a position different from a position of the press-fitted portion, the restriction portion restricting at least a part of the conductor from being displaced in a direction different from the press-fitting direction from a time point when press-fitting of the conductor into the press-fitted portion is started to a time point when the press-fitting is completed.

A terminal block includes a lower bus bar and an upper bus bar that overlap each other at overlap portions and an insulating middle cover disposed between the overlap portion of the lower bus bar and the overlap portion of the upper bus bar. The lower bus bar and the upper bus bar are provided with their respective ones of first to fourth terminals exposed from the middle cover, at positions different from the overlap portions and the first to fourth terminals are disposed at positions radially spaced apart from the overlap portions.

A board-to-board plug, comprising an insulating seat (20) integral to a metal insert (30), several signal terminals (40) arranged inside the insulating seat (20), and a shielding housing (10) coated outside the insulating seat (20). The insulating seat (20) comprises an engagement end (21) provided with terminal slots (214), terminal blocks (24) formed by extending from the engagement end (21) to the rear direction, and a pair of extension arms (22) formed by extending from both transverse sides of the terminal block (24) to the rear direction. The metal insert (30) comprises a board body portion (31) formed between a pair of extension arms (22), and several grounding terminals (37) bent from the front end of the board body portion (31) and extending into the terminal slots (214). The grounding terminals (37) and the signal terminals (40) are arranged at intervals.
