A shielding shell used to at least partially surround signal terminals includes a first side wall, a second side wall and a third side wall. The second side wall connects the first side wall and the third side wall. The first side wall and the third side wall are disposed face to face. An end of at least one of the first side wall, the second side wall and the third side wall includes a deflection portion bent inwardly. The deflection portion is used to guide insertion of the shielding shell into a mating connector. As a result, a better shielding effect on the signal terminals can be provided. Besides, it is easy to guide insertion of the shielding shell into the mating connector.

A backplane connector includes a housing, a number of terminal modules assembled to the housing, and a metal shield surrounding member. The housing includes a base, a first side wall and a second side wall. The base, the first side wall and the second side wall jointly form a receiving space for at least partially receiving a mating connector. The terminal module includes a first signal terminal, a second signal terminal and an insulating block fixed on the first signal terminal and the second signal terminal. The metal shield surrounding member at least partially surrounds the periphery of the first signal terminal and the second signal terminal. As a result, the shielding effect of the backplane connector is improved.

A backplane connector includes a number of conductive terminals, an insulating frame, a first metal shield and a second metal shield. Each conductive terminal includes a connection portion and a contact portion. The conductive terminals include differential signal terminals, a first ground terminal and a second ground terminal. The first metal shield has a first elastic arm and a second elastic arm. The second metal shield has a third elastic arm and a fourth elastic arm. The first elastic arm and the third elastic arm are in contact with two opposite side surfaces of the contact portion of the first ground terminal. The second elastic arm and the fourth elastic arm are in contact with two opposite side surfaces of the contact portion of the second ground terminal. This arrangement increases the grounding shielding area, reduces crosstalk, and improves the quality of signal transmission.

The base, the first side wall and the second side wall jointly form a receiving space. The terminal module includes a first signal terminal and a second signal terminal. The housing includes a number of insulating protrusions integrally extending from the base. The insulating protrusions extend into the receiving space. The terminal modules are assembled in the insulating protrusions. Compared with the prior art, the insulating protrusions of the present disclosure is integrally formed with the base, thereby improving the structural strength of the housing and improving the durability of the backplane connector.

A connector with a tolerance module includes a socket and a plug adapted to the socket, wherein the socket includes a first housing, the plug includes a tolerance module and a third housing, the tolerance module includes a second housing, the second housing includes second contact members, the second housing is movably arranged on the third housing in a direction perpendicular to the axial direction of the connector, and the second contact members are floatingly assembled in the second housing to enable displacement in the direction perpendicular to the axial direction of the connector. The second housing only generates translational motion without displacement when the connector is inserted. The tolerance of the plug and the socket is realized by the floating assembly of the second contact members in the second housing.

Provided is an electrical connection box according to which it is possible to suppress the occurrence of mistakes in a manufacturing process, and it is possible to reliably prevent the occurrence of faulty products. The electrical connection box to be used in a vehicle includes a terminal having an inner-fitting plate portion that is fit into and held in a slit of a holding member; and multiple substrate connection portions that protrude along a surface of the inner-fitting plate portion from one side edge of the inner-fitting plate portion. The terminal has a shape that is asymmetrical in a direction in which the multiple substrate connection portions are arranged side by side.

Printed circuit board assemblies (PCBAs) are a fundamental component used in nearly all electronics. PCBAs provide electrical connections and mechanical support to electronic components and are generally made of copper layers laminated onto, though, and/or between one or more non-conductive substrate layers. Press-fit pin connections are often driven through the non-conductive substrate layers to connect power or ground across multiple conductive copper layers within a PCBA and/or connect electronic components on opposing sides of the substrate layer(s). Some new PCBA designs utilize fewer, but larger contact pins (e.g., power pins) in place of a greater number of smaller contact pins. With larger contact pin sizes, press-fit pin connections become more difficult to achieve with repeatable reliability in electrical connection without damaging surrounding features in a PCBA. The press-fitting assembly fixtures, contact pins, and methods described herein are capable of repeatable reliability and avoiding open and short failures.
