Multiple grooves are concavely provided inward from the outer side edge. Two protruding blocks protrude toward each other and inward each of the grooves from two opposite sides of each of the grooves. The base plate has multiple strip connecting portions. Prior to the insert-molding, the strip connecting portions are integrally connected to a same strip. After the insert-molding, the strip connecting portions are broken from the strip, each strip connecting portion is located in a corresponding groove, and upper and lower surfaces of each strip connecting portion are exposed in the corresponding groove. The strip connecting portions do not exceed outward beyond the outer side edge. Two opposite sides of each strip connecting portion abut the two protruding blocks.

An electrical connector includes multiple terminals formed by cutting from a metal plate and bending. The portion of the metal plate with the terminals being removed is defined as a base plate. Each terminal has a base portion and an elastic arm connected thereto. The base portion is at least partially horizontally provided to be coplanar to the base plate. A cutting slot is formed between the base plate and the base portion. A through slot is formed between the base plate and the elastic arm. An insulating body is provided with through holes running vertically therethrough. A portion of the cutting slot and the through slot are exposed in a corresponding through hole. The terminals include signal terminals and ground terminals. The base plate forms a connecting portion between the through slot and the cutting slot of each ground terminal to be connected to the ground terminal.

A connector includes a rectangular flat-plate housing including a first positioning hole and a second positioning hole, and a contact row and a contact row held on the housing. The housing includes a first pitch side surface and a second pitch side surface on an opposite side of the first pitch side surface. The contact row and the contact row extend from the first pitch side surface to the second pitch side surface. The first positioning hole is disposed between the first pitch side surface and the contact row, and the second positioning hole is disposed between the first pitch side surface and the contact row.

Embodiments include a transmission line-land grid array (TL-LGA) socket assembly, a TL-LGA socket, and a package substrate. The TL-LGA socket assembly includes a TL-LGA socket having an interconnect in a housing body, the interconnect includes a vertical portion and a horizontal portion. The housing body has a top surface and a bottom surface, where the top surface is a conductive layer. The TL-LGA socket assembly also includes a package substrate having a base layer having a signal pad and a ground strip. The base layer is above the conductive layer of the housing body of the TL-LGA socket. The ground strip is above the horizontal portion of the interconnect and adjacent to the signal pad. The horizontal portion is coupled to the signal pad on the base layer. The package substrate may have a pad with a reduced pad area.

A power-inlet plug has an installation seat, an elastic electrical conductive member and an external connector, the elastic electrical conductive member having a fixing portion and an elastic portion electrically connected to the fixing portion, the installation seat is provided with an installation cavity that accommodates the fixing portion and the external connector and a locking mechanism for detachable fix of the installation seat, the installation cavity is provided with an hole providing for the elastic portion extending out, and the elastic portion is provided with a retractable electrical contact. By setting the stop block, the permanent deformation and collapse of the shrapnel can be effectively prevented, and the problems of poor contact and contact failure can be solved. The locking part drives down the locking tongue and the power supply track extrusion locking structure design, effectively prevents the power-inlet plug from falling off.

A connector includes a flat-plate housing made of insulating resin and a contact held on a housing by press-fitting. The housing includes a press-fitting space and a solder connection checking hole. The contact includes a press-fit part to be press-fit into the press-fitting space, and a soldering part that extends from the press-fit part and is connected by soldering to a pad of an input-output board. The solder connection checking hole is formed to penetrate the housing in the vertical direction and allow a solder fillet, which is formed when the soldering part is soldered to the pad of the input-output board, to be checked through the solder connection checking hole. The housing includes a separating wall that separates the press-fitting space from the solder connection checking hole.
