Each latch opening extends through the bottom wall and through a side wall and is configured to allow a latch to eject a mating connector by moving within the opening.
System and apparatus for network device heat management
Embodiments relate generally to network system and apparatus for heat management of high volume network devices. More specifically, disclosed are system and apparatus that provide for improving heat dissipation of the network devices through improved air circulations, including a PCB with at least one slot and a connector cage mounted on the printed circuit board, the connector cage being within a certain distance from the at least one slot in the PCB.
A connector assembly includes a first connector having a first terminal and a second terminal which are used for fitting detection, a second connector fitted with the first connector, a manipulation lever for use in fitting the second connector with the first connector along a fitting direction, a fitting lock mechanism adapted to lock a fitting state of the first connector and the second connector and a fitting detection mechanism disposed at the second connector and adapted to short-circuit between the first terminal and the second terminal when the first connector and the second connector are fitted with each other, the fitting detection mechanism having a first contact point, a second contact point and a third contact point that are arranged in series between the first terminal and the second terminal when the first connector and the second connector are fitted with each other.
Electrical connector latch
A latch for securing and ejecting a mating connector from a connector housing includes a hinge portion configured to pivotably attach the latch to a connector housing, an arm portion extending from a first side of the hinge portion along a first direction, and a pair of discrete spaced apart hinge arms extending from an opposite second side of the hinge portion along a second direction different than the first direction. The hinge arms are configured to eject the mating connector through a pair of corresponding spaced apart latch openings extending through a bottom wall and through side walls of the connector housing.
A connection assembly is described. The connection assembly has a substrate having at least two electrically conductive structures, a housing, which is connected to the substrate on the bottom by an adhesive fastening, the housing has a plug receptacle having at least two plug contacts, the plug contacts are connected to at least two contact pads via electrical conductors, and the contact pads connected in an electrically conducting fashion to the electrically conductive structures, the angle between the plug-in direction into the plug receptacle and the bottom of the housing lying between 15° to 90°.
Waterproof electrical connector and method for making same
An electrical connector includes: a terminal module including an insulative housing and a number of terminals insert molded with the housing, the housing including a base and a tongue extending forwardly from the base; a metallic shield enclosing the terminal module; and a sealing member positioned in front of the base and sealed between the terminal module and the shield. A related method of making includes: enclosing a metallic shield about a terminal module; inserting a terminal protector into a front mating port of the shield and module combination until abutting a part of the terminal module; and applying a sealing material via the front mating port into a space defined between the terminal module and the shield to form a sealing member.
Provided is a connector that has a male connector that includes a male terminal and a locking section, an aligning plate that engages with the male terminal in order to protect the male terminal, that is freely movable with respect to the male terminal, that is provided with an engaged portion and a locked portion that is provided to a surface on the proximal end side of the male terminal, and that is configured so that movement toward the proximal end side of the male terminal is blocked in a state in which the aligning plate is provisionally mounted on the male connector; and a female connector that has an engaging portion that engages with the engaged portion of the aligning plate when the female connector is removed from the male connector, and that moves together with the aligning plate in a direction leading away from the male connector.
