摘要:
A socket assembly configured to be reflow soldered to a circuit board comprising a perimeter frame having a central open area surrounded by perimeter walls. The socket assembly may be configured to be surface mounted on a circuit board, wherein at least one of the perimeter walls includes a post extending downward therefrom. The socket assembly also comprises a base fit into the open area of the perimeter frame. The base is separate and distinct from the socket frame. The base has a post hole therein positioned to mate with the post. Additionally, the socket assembly comprises contacts held by the base, and solder balls provided on a bottom of the base. The solder balls engage the contacts and, prior to, and after, soldering, extend beyond a bottom of the socket frame.

Electrical connectors (40, 104) including contact terminals that can be unmated without previously disconnecting power include main contacts (12, 112) and auxiliary contacts (16, 130) that are shunted by a positive temperature coefficient (PTC) resistor (6, 140) located between the main and auxiliary contact. The main contact (12, 112) will be disconnected first and the auxiliary contact (16, 130) can be longer than the main contact (12, 112). Arcing will not occur at the mating end of the main contact (12, 112), because the current will be shunted to the still connected longer auxiliary contact (16, 130). I2R heating will increase the resistance in the PTC resistor (6, 140), so when the auxiliary contact (16, 130) is disconnected, current will be below the arcing threshold. Multiple latches (54A,B) and (60A,B) or (180) and (196) permit only discontinuous mating and unmating or two state mating and unmating of electrical connectors, so that the connectors can be disconnected without arcing for a range of currents.

摘要:
A touch sensor comprises a substrate capable of propagating acoustic waves and includes a first surface having a touch sensitive region. A first sidewall intersects the first surface along a first edge. The first edge is configured to propagate a first acoustic wave along the first edge. The first acoustic wave may be a one-dimensional edge wave. A wave converter converts the first acoustic wave to a second acoustic wave, and the first surface is configured to propagate the second acoustic wave across the touch sensitive region.

A wedge connector assembly includes a spring member having a generally C-shaped body with an inner surface, and a wedge member having opposed first and second sides. The wedge member is mated with the spring member such that the wedge member is configured to securely retain a first conductor between the first side and the spring member and a second conductor between the second side and the spring member. The wedge member has at least two final mating positions based on the orientation of the wedge member with respect to the spring member. Optionally, the wedge member may have two orientations, namely a first orientation and a second orientation, wherein the first and second sides are flipped with respect to one another in the first and second orientations. A top of the wedge member may engage the inner surface in the first orientation and a bottom of the wedge member may engage the inner surface in the second orientation.
摘要:
An electrical bushing connects a power distribution component with a power line. The electrical bushing includes a connection terminal that is configured to connect with the power distribution component. A core component of the electrical bushing defines a socket that is configured to receive a contact pin associated with the power line. The electrical bushing also includes a radial interposer spring that is configured to complete an electrical connection between the contact pin and the core component when the contact pin is inserted into the socket.

An electrical connector includes a socket that is configured to provide a current path between a connection terminal and a contact pin inserted into the socket during a standard connection. A slider component of the electrical connector is configured to move relative to the socket to make contact with the contact pin and provide a current path between the connection terminal and the contact pin during a fault condition connection.

An electrical connector assembly includes a first conductive member having a first hook portion extending from a first base wedge portion and adapted to engage a first conductor, and a second conductive member having a second hook portion extending from a second wedge portion and adapted to engage a second conductor. The first wedge portion and the second wedge portion are adapted to nest with one another and be secured to one another. Each of the first and second conductive members includes a visual alignment indicator to define a final mating relation between the first and second conductive members once fully mated.
摘要:
An electrical connector for mating with a plurality of contacts separated from one another by a nominal pitch value includes an array of contact surfaces having a first dimension measured in a direction perpendicular to a mating direction between the plurality of contacts and the array of contact surfaces. The first dimension is greater than the nominal pitch value, thereby assuring electrical contact between the contacts and the contact surfaces despite an actual deviation from the nominal pitch.
