The present disclosure provides an electrical connector. The electrical connector comprises an insulative housing and a plurality of terminals disposed in the insulative housing. The insulative housing comprises a top face, a bottom face opposite to the top face, and a plurality of side faces extending between the top face and the bottom face. A corner portion between at least two adjacent side faces of the side faces is formed as a chamfered surface. Such a configuration reduces the dimension of the electrical connector, enables a more compact arrangement of components on the electronic system, and enables the dimension of the electronic system to be reduced, such that the entire assembly, including the electrical connector and the electronic system, can be manufactured at a lower cost and can be more compact and more lightweight.

An electrical connector mountable to a substrate (e.g. a Printed Circuit Board, PCB) can include a terminal housing having a front wall and an opposing back wall. An opening is provided in the front wall for receiving a plug inside the terminal housing, opposing side walls, and a top wall and an opposing bottom wall. The bottom wall has an inner surface facing the inside of the terminal housing and an outer surface facing away from the inside of the terminal housing. The outer surface (can have at least two retention pins projecting from the outer surface for being inserted into corresponding holes in the PCB. A first retention pin can be positioned on the outer surface so as to be arranged asymmetrically with respect to a second retention pin.

An electronic module includes a module substrate has an upper surface and a lower surface. The module substrate has a package pad array having package contact pads at the upper surface. The module substrate has a socket pad array having socket contact pads at the upper surface. The module substrate has guide pin locating pads associated with the socket pad array. The electronic module has an electronic package coupled to the package contact pads at the package pad array. The electronic module has guide pins surface mounted to the guide pin locating pads. The electronic module has a socket assembly coupled to the module substrate. The socket assembly has a socket housing holding socket contacts. The socket contacts are coupled to the socket contact pads at the socket pad array. The socket frame including pockets receiving the guide pins to locate the socket assembly relative to the module substrate.

Looseness of two housings are suppressed. A connector includes a lower housing and an upper housing. The lower housing is provided with a locking portion. The upper housing is provided with an elastic locking piece that is hooked on the locking portion. The elastic locking piece has a cantilever shape, and restricts relative movement of the lower housing and the upper housing in a separation direction, which is a direction opposite to a coupling direction. The lower housing is provided with a protruding piece portion that protrude outward in a left-right direction. The upper housing is provided with a protruding piece restriction portion that restricts movement of the protruding piece portion. The protruding piece restriction portion is provided with an inclined surface that is inclined in an assembly direction to reduce a movable range of the protruding piece portion in a separation direction.

To effectively prevent damage and position displacement of a die to provide an electric connector having a shield housing space with accurately-controlled shape and size. The electric connector includes a housing having a base and a plate-shaped body, multiple first terminals provided on one plate surface of the plate-shaped body and multiple second terminals provided on the other plate surface facing the one plate surface, a shield arranged among the multiple first terminals and the multiple second terminals, and a metal shell forming, between the one plate surface and the other plate surface, a fitting space in which a partner connector is to be fitted. The base has a first housing portion for housing part of the shield. The plate-shaped body has a second housing portion for housing another part of the shield. The second housing portion is communicated with the first housing portion in the direction of fitting to or release from the partner connector. The second housing portion is, in the fitting-release direction, communicated with through-holes provided at an end wall of the plate-shaped body positioned on the side of fitting to the partner connector.

A connector includes a flat-plate housing made of insulating resin and including a first positioning hole and a second positioning hole, a plurality of contacts held on the housing, and a first hold-down and a second hold-down made of metal and disposed to correspond to a first positioning hole and a second positioning hole, respectively. The housing includes a CPU board opposed surface to be opposed to a CPU board. The first hold-down includes a reinforcing plate part to cover the CPU board opposed surface around the corresponding first positioning hole. The second hold-down includes a reinforcing plate part to cover the CPU board opposed surface around the corresponding second positioning hole.

According to an embodiment, a housing of a high-speed transmission connector fitted to a connector of a counterpart substrate via a frontage. The housing of the first aspect includes: a bottom plate forming a bottom of the frontage and being provided with at least one boss on a surface opposite to the frontage side; a pair of first side walls facing each other in a first direction with the frontage sandwiched therebetween; and a pair of second side walls facing each other in a second direction orthogonal to the first direction with the frontage sandwiched therebetween. The bottom plate is provided with first through holes for tolerance measurement having inner peripheral surfaces including side wall surfaces of the first side walls in the same planes and/or second through holes for tolerance measurement having inner peripheral surfaces including side wall surfaces of the second side walls in the same planes.

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.

Modular block type of board connector having two different types of RF connectors and an optical cable with an optical connector. A RF connector with built-in impedance tuning and automatic biasing.

An electrical connector includes an insulating body, a first installation module and a second installation module. The first installation module includes a first internal circuit board and a first terminal adapter block. The second installation module includes a second internal circuit board and a second terminal adapter block. The first internal circuit board and the first terminal adapter block include first fool-proof portions that cooperate with each other. The second internal circuit board and the second terminal adapter block include second fool-proof portions that cooperate with each other. The first fool-proof portions are different from the second fool-proof portions, thereby preventing the first terminal adapter block from being incorrectly connected to the second internal circuit board, and preventing the second terminal adapter block from being incorrectly connected to the first internal circuit board. The present disclosure also relates to an electrical connector assembly having the electrical connector.
