An anti-vibration and heat dissipation structure for a memory socket includes a circuit board, a heat dissipation pad, and a heat dissipation shell. The circuit board includes memory sockets for insertions of memory modules. The heat dissipation pads are disposed on upper and lower surfaces of memory modules, respectively, to upwardly conduct heat, generated by the memory modules to the topmost heat dissipation pad via a stack structure of the memory modules and the heat dissipation pads. The heat dissipation shell comprises a maintenance window, and a cover board disposed on the maintenance window and having a bottom surface abutted with the topmost heat dissipation pad, to form a vertical position-limiting and anti-vibration structure to conduct heat to the heat dissipation shell via the cover board for dissipation, and easy maintenance of the memory modules via the maintenance window is also achieved.

A hermetically-sealed edge-connect header that can withstand high temperatures, high pressures (or high vacuum levels), and high vibration environments, along with two corresponding connectors are disclosed. After brazing the edge-connect header components, the assembly is machined to form a slot with a portion of each of a plurality of electrical conductors removed in the machining process, resulting in a header with a high pin density. During the process of mating the first connector design to the edge-connect header, a plurality of wipers in the connector deflect, thereby causing the wipers to extend from the connector and contact the corresponding electrical conductors in the header. During the process of mating the second connector design to the edge-connect header, each of a plurality of wipers formed of low-mass, compliant metal wool, forms multiple contact points with a corresponding electrical conductor in the header.

Various techniques are provided for displacing air from partial discharge sensitive regions of a connector of a low partial discharge high voltage connector to other regions of the low partial discharge high voltage connector where electrical flux is reduced. A plug member is mated with a receptacle member to provide the connector, with a seal member disposed in a cavity provided by the plug member and/or the receptacle member. In response to the mating, the seal member is compressed at an initial contact region between an innermost layer and an outermost layer of the seal member. In response to the compressing, air is forced radially inward toward the innermost layer and radially outward toward the outermost layer away from the initial contact region to reduce partial discharge associated with the connector. Additional methods and systems are also provided.

An electrical connector apparatus for use in a downhole tool comprising a housing, a contact screw within outer threads and inner threads, a contact plunger within the inner bore of the housing and a second cylinder protruding from the first cylinder. The contact spring is located between the contact plunger and the contact screw and pre-loads the contact plunger within the housing.

The device for use in an explosive atmosphere zone has a device housing and at least one energy supply part that is provided with at least one battery or at least one rechargeable battery as well as energy-associated supply contacts. The energy-associated supply contacts interact with device-associated supply contacts when the energy supply part is connected to the device. The energy-associated and device-associated supply contacts have connected upstream thereof switches that, prior to separation of the energy supply part from the device, can be controlled by a circuit such that the switches deenergize the energy-associated and the device-associated supply contacts.
