Provided is an electrical connection cassette with which it is possible to freely expand a device and add functions in accordance with the size of free space. An electrical connection cassette is provided with: a circuit board; and first connection terminals and second connection terminals mounted on the circuit board and having terminal shapes that can be engaged with each other. In a state with a terminal connection direction oriented in a predetermined direction with respect to the circuit board, the first connection terminals are disposed on the side of one main surface of the circuit board, and in a state with a terminal connection direction oriented in a direction parallel to the predetermined direction, the second connection terminals are disposed near the other main surface of the circuit board.

An electrical assembly includes a circuit board, a shunt busbar; a connector including a first conductive resilient member and a second conductive resilient member, and a controller. The first conductive resilient member and the second conductive resilient member may be disposed substantially between the circuit board and the shunt busbar. The first conductive resilient member and the second conductive resilient member may electrically connect the controller with the shunt busbar.

A terminal block 1 includes a plate-like pedestal portion 10 provided with open collar mounting holes 12, and tubular collars 20 to be mounted into the collar mounting holes 12. An inner surface of the collar 20 is so tapered that an inner diameter decreases from one opening 13 of the collar mounting hole 12 toward another opening 13 of the collar mounting hole 12.

A modular power distribution device for vehicles that couples to adjacent devices mechanically and electrically without a common housing or mounting plate. The devices share user selectable electrical connections internally to change the function of the devices and reduce the complexity of adding additional devices. The electrical contacts on the device are protected by a weather-resistant seal created when the device engages with wiring, adjacent devices or the provided covers. Covers may also house a communications receiver/transceiver and a microcontroller to control the device using wired or wireless communications. A mounting bracket is removably attached to each device and may be separated from the device without removing the mounting bracket from the vehicle. Each device can couple to a preceding device while the preceding device remains mounted to a substrate and connected to wiring. The devices may house semiconductor relays or electromechanical relays for use in direct current electrical systems.

A module element is provided for accommodating pluggable contact means and/or functional elements to provide an assembled plug connector module. The module element has a retaining contour arranged and designed in such a way that a first module element can be joined with a second module element in a transverse direction, and/or the module element has a fastening contour and at least one fastening element, which are arranged and designed correspondingly in such a way that a first module element can be joined with a second module element in the transverse direction to form the plug connector module. A plug connector module composed of at least two of the module elements described above is also provided.

A block terminal for a motor includes a block base, a busbar, bushings, and fixing nuts. The busbar is disposed in the block base and includes end portions protruding outward from the block base. The end portions include coupling holes. The bushings are mounted on sides of the block base. The fixing nuts are insert-mounted in the coupling holes of the busbar.

A connecting terminal having a plurality of conductor connection modules, wherein the conductor connection modules each have an insulating material housing with a conductor insertion opening for receiving an electrical conductor. In each case two conductor connection modules arranged next to one another are connected via a web, wherein the web is designed flexibly in such a way that the conductor connection modules can be arranged from an initial position into an arrangement different from the initial position, and vice versa.

Provided is a molding method of a sealing cover, realized by setting up a sealing cover mold, the mold includes a cavity and a core group arranged in the cavity, including setting up a first core and a second core, the mold opening direction of the first core and the second core are not parallel. The present application does not need a process hole to perform the injection molding of the sealing cover with a fastening structure, whose sealing is also better.
