A method of making printed circuit board vias using a double drilling and plating method is disclosed. A first hole is drilled in a core, the first hole having a first diameter. The first hole is filled and/or plated with an electrically conductive material. A circuit pattern may be formed on one or two conductive layers of the core. A multilayer structure may then be formed including a plurality of cores that also include pre-drilled and plated via holes, wherein at least some of the pre-drilled and plated via holes are aligned with the first hole. A second hole is then drilled within the first hole and the aligned pre-drilled and plated holes, the second hole having a second diameter where the second diameter is smaller than the first diameter. A conductive material is then plated to an inner surface of the second hole.

A fuse module including a mounting block formed of an electrically insulating material, a fuse plate including a fusible element disposed on a bottom surface of the mounting block, an input terminal electrically connected to the fusible element and extending along rear and top surfaces of the mounting block, and a fuse terminal electrically connected to the fusible element and extending from a front surface of the mounting block, the fuse module further including an electrically conductive terminal post extending from the top surface of the mounting block through the fuse terminal for facilitating connection to an electrical component.

The invention concerns a fuse box, comprising a busbar (6) and at least one fuse (8) connected to the busbar, each fuse including two opposite end portions (8A, 8B) and a central portion (82), at least the central portion of each fuse and a section of the busbar being encapsulated in a plastic coating layer. The central portion (82) includes a part (84) of reduced cross-section. The two end portions (8A, 8B) include two respective electrical connectors (81A, 81B), and at least the two electrical connectors (81A, 81B) of each fuse (8) are not encapsulated in the plastic coating layer, so that a new fuse (12) can be connected between the two electrical connectors (81A, 81B) in replacement of a blown fuse (8).

A fuse module including a mounting block formed of an electrically insulating material, the mounting block having a rear wall extending from a base, a fuse plate including an electrically conductive bus bar disposed adjacent a rear surface of the rear wall, a fusible element electrically connected to the bus bar and disposed adjacent a front surface of the rear wall, and a fuse terminal electrically connected to the fusible element and extending onto a top of the base. The fuse module may further include an electrically conductive terminal post extending from the top of the base through the fuse terminal for facilitating connection to an electrical component.

A straight bus bar includes an axial direction and having a rigid first portion with a first contact surface connectable to a first fuse, an axially spaced rigid second portion with a second contact surface connectable to a second fuse, and a connecting portion electrically connecting the first portion and the second portion. The connecting portion is a resilient compensation portion having at least two lateral recesses extending from opposite sides into the bus bar making the connecting portion elastically bendable to allow a relative axial movement of the first and second portions when an axial force is applied to the bus bar.

A fuse housing assembly and a fuse kit are provided. The fuse housing assembly and the fuse kit are configured to allow for fuses having terminals of different sizes to be mounted onto a circuit board. The fuse housing assembly and the fuse kit include a spacer configured to protect the exposed portions of the fuse terminals from the environment and prevent the proximal ends of the fuse terminals from breaking the fuse elements. Further, the spacer retains the fuse body of the respective fuses and the fuse terminals in a fixed position relative to each other so as to prevent the fuse terminals from being bent.

A breaker device for connecting in an electrical circuit, the device includes a pyrotechnic initiator and a body having present therein: a pressurizing chamber in communication with an outlet from the pyrotechnic initiator; at least one electrically conductive portion for connection to the electrical circuit; at least one fusible element connected in series with the conductive portion, the initiator being connected to the terminals of the fusible element and the fusible element being configured to trip when the current passing through it exceeds a predetermined value, thereby actuating the initiator; and a movable breaker element; the pyrotechnic initiator being configured to cause the breaker device to pass from a current-passing first configuration to a circuit-breaking second configuration, the movable breaker element being moved on passing from the first configuration to the second in order to disconnect the conductive portion.
