An electrical device heat dissipation structure includes an air blowing device, a casing, and a mating connector. The casing is disposed with at least one air outlet, an electrical connector and a power supply. The power supply provides power to the air blowing device. The mating connector has a chip. The mating connector is electrically connected with the electrical connector. The air blowing device is configured to blow air to the mating connector through the at least one air outlet, so as to improve dissipation of heat generated by the chip at work, and to reduce a temperature of the mating connector.

An electrical connector includes a housing defining a base portion and a tongue portion, two rows of terminals and a shielding shell. The tongue portion defines a thickened step at a root to the base portion, the base portion defines a front and a rear side, and an upper and a lower retaining slots. The shell is retained on the base portion and surrounding the tongue portion so as to define a mating cavity between the shell and the tongue portion. The shell defines an upper and a lower-front stopping portions inwardly received in corresponding retaining slots to prevent a forward movement of the housing. The upper and lower front stopping portions extend forwardly into the mating cavity across the front side of the base portion so as to prevent a mating connector from damaging the housing during the mating connector is inserted into the mating cavity.

A heat sink assembly includes a casing having an opening, a main board accommodated in the casing, a heat sink mounted on the main board, an electrical connector mounted on the main board and exposed in the opening, a mating connector located outside the casing and connected to the electrical connector through the opening in a plugging manner, and a heat conductor, disposed inside the casing. The mating connector has a chip that is electrically connected to the electrical connector. One end of the heat conductor is connected to the heat sink, and the other end of the heat conductor is thermally connected to the electrical connector or the mating connector, so that heat generated by the chip during working can be transferred to the heat sink through the heat conductor, thereby reducing a temperature of the mating connector.

A sensor device includes a mounting member having fixation surfaces inside, and at least one electronic component directly or indirectly fixed to the fixation surfaces of the mounting member, and the mounting member constitutes a part of a casing for housing the electronic component. Further, the fixation surfaces are perpendicular to each other.

Further, the fixation surfaces are perpendicular to each other.

A cable backplane system includes cable backplanes each including a tray configured to be coupled to a chassis and a plurality of cable connector assemblies mounted to the tray. The tray has a plate extending between a front and a rear with mounting locations receiving corresponding cable connector assemblies. The trays are oriented parallel to each other with front openings between the fronts of the plates and rear openings between the rears of the plates. Each cable connector assembly has a housing holding contacts terminated to corresponding cables. Each cable connector assembly has a holder mounted to the corresponding mounting location of the plate. The holder is mounted to the plate and removable from the plate through the rear opening at the rear of the plate.

A surface mount electrical connector and methods of making and using a surface mount electrical connector. The connector includes a housing and a contact subassembly received in the housing. The contact subassembly includes interface contacts, board termination contacts, and an internal circuit board. The interface contacts and the board termination contacts are mounted to the internal circuit board to electrically connect the interface contacts and the board termination contacts through the internal circuit board. Each of surface mount tail ends of the board termination contacts has a bent portion that defines a mounting surface configured to be surface mounted to a mounting face of a main circuit board, to establish an electrical connection between the board termination contacts and the main circuit board.

A backplane connector includes a housing and a number of terminal modules assembled to the housing. 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. 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.

An electrical connector comprises an insulative shell having a floor; a first plurality of contacts extending through the floor, wherein the first plurality of contacts are disposed in a plurality of columns; a second plurality of contacts extending through the floor, wherein the second plurality of contacts are interspersed with the first plurality of contacts within the plurality of columns; and a conductive member adjacent the floor. The conductive member comprises a first plurality of openings, wherein the first plurality of contacts extend through the openings of the first plurality of openings; a second plurality of openings, wherein the second plurality of contacts extend through the openings of the second plurality of openings; and a first plurality of tabs, extending into openings in the insulative shell.

A connector is provided with a connecting member including a contact point portion, a housing for holding the connecting member and a protecting member displaceable with respect to the connecting member to a protection position for protecting the contact point portion and a connection position for bringing the contact point portion into contact with a circuit board. The housing includes a lock portion for holding the protecting member at the protection position.
