Switchable grounded terminal loads are built into, or otherwise coupled to, connectors on motherboards and control devices. The terminal loads are coupled to the bus termination at the connector when the connector is stuffed (connected to a mating connector). The switchable grounded terminal loads replace dummy connectors in preventing empty unstuffed connectors from increasing error risks on active channels.

An electric contact having a contact resistance that is hardly increased even if the electric contact is repeatedly used for a long period of time. A base material of an electric contact is provided with a first contact part that is in contact with a first electrode of a first electric component, a second contact part that is in contact with a second electrode of a second electric component, and a spring part that presses the first contact part to the first electrode, and a wear-resistant contact point film is formed on a distal end portion of the first contact part. Furthermore, a highly conductive film is formed between a region of the wear-resistant contact point film and a distal end portion of the second contact part in the base material.

The present disclosure relates to an electrical contact assembly of a plug-in connection terminal, which has an electrical contact having a first connector element for connecting a plug-in contact in a plug-in direction, a second connector element for connecting an electrical conductor in a clamping manner being arranged on the electrical contact, the first connector element having at least one contact element that has at least one first section and one second section, the width of the first section at a right angle to the plug-in direction being greater than the width of the second section at a right angle to the plug-in direction.

An electrical connector includes an insulating body having multiple receiving holes, and multiple conductive terminals respectively received in the receiving holes. Each conductive terminal has first and second elastic arms, and third and fourth elastic arms. When a chip module downwardly presses the conductive terminals, the first elastic arm are conducted upwardly with the chip module, and the third elastic arm are conducted downwardly with a circuit board. At the same time, the first elastic arm elastically deform to urge against the second elastic arm, and the third elastic arm elastically deform to urge against the fourth elastic arm, thereby forming two conductive paths to reduce terminal impedance, and improving signal transmission performance. Further, the second elastic arm provide elastic force for the first elastic arm and the fourth elastic arm provide elastic force for the third elastic arm.

Each contact is designed in such a way that one contact part is supported by two spring pieces extending apart from each other in a pitch direction and parallel to each other and whose both ends are joined. The two spring pieces of each contact are extended toward each other so that the two spring pieces of each contact come closer to each other in the pitch direction while maintaining a predetermined pitch and an outer spring gap, thereby increasing the contact pressure of each contact while maintaining the predetermined pitch and the impedance of each contact.

A board-to-board connector includes an insulating body and a conductive terminal. The conductive terminal includes a mounting portion, a first resilient arm and a second resilient arm. The mounting portion includes a main body portion and at least one tab protruding from the main body portion. The first resilient arm includes a first connecting portion, a first elastic arm, a first contact portion, a first extension arm and a first end portion. The second resilient arm includes a second connecting portion, a second elastic arm, a second contact portion, a second extension arm and a second end portion. When the first circuit board and the second circuit board abut against the corresponding first contact portion and the second contact portion, the first extension arm is in contact with the second end portion and/or the second extension arm is in contact with the first end portion.

An apparatus comprising: a barrel having an first hole and a second hole opposite to the first hole; a first plunger disposed in the first hole and including a hook shape; a second plunger disposed in the second hole; and an elastic connection member disposed within the barrel to connect the first plunger and the second plunger.

An electrical connector includes an insulator adapted to be downwardly assembled into the housing of the cradle, and a set of contacts upwardly assembled into the insulator. Each contact includes a vertical retention section received in the corresponding retention slot in the insulator via an upward insertion process, and an upper spring arm extending from an upper edge of the retention section for mechanically and electrically connecting to the machine case, and a lower spring arm extending from a lower edge of the retention section for mechanically and electrically connecting to the cable. The free end of the upper spring arm is downwardly abutted against by the insulator while that of the lower spring arm is not.

An electrical connector comprises an insulative housing and a plurality of conductive terminals. The terminals are respectively provided in grooves of the housing. Each terminal has a portion fixed to the housing, an upper elastic portion extending from a top end of the fixed portion and a lower elastic portion extending from a bottom end of the fixed portion. The upper portion has a first arm extending from the fixed portion, a first contact section extending from the first arm, extending out of a top surface of the housing and bending, and a second arm extending from the first section, and a distal end of the second arm abuts against abutted structures in the corresponding groove when the first section is pressed down.
