An electronic device includes a first main body, a first electrical connector, and an insert member. The first main body has an insertion end and one or more holes located at the insertion end. The first electrical connector is disposed at the insertion end. The insert member is coupled to the first main body through the one or more holes and includes a plurality of ribs and a plurality of removed portions. Each of the ribs extends away from the insertion end. The ribs and the removed portions are sequentially and linearly arranged according to a coding pattern.

In various representative aspects, an assembly for connecting and electrically bonding electronic equipment to solar panel frames is provided. The present invention relates generally to an assembly for supporting junction box structures used in a solar panel frame array. More specifically, the apparatus comprises an adjustable bracket assembly that can mount most sizes and shapes of junction boxes that are then secured virtually to any solar panel frame while being electrically bonded by way of a surface layer penetrating means.

A connection structure includes: a circuit breaker connected to a power cable through which high-voltage power is supplied; a high-voltage device box accommodating the circuit breaker; a main transformer configured to transform a voltage of the high-voltage power and provided under the floor of the car; a first connector device electrically connected to the circuit breaker and provided at a dividing wall of the high-voltage device box; a second connector device electrically connected to the main transformer and provided at a dividing wall of the main transformer; and a high-voltage cable covered with an insulating coating and having both end portions to which cable connector portions are respectively attached, wherein the high-voltage cable connects the first connector device and the second connector device in such a manner that the cable connector portions respectively fit and are connected to the first connector device and the second connector device.

The present invention relates to a housing of an electric/electronic equipment, such as a luminaire, terminal box, control device, switching distributor or the like, comprising at least one lateral surface facing the surroundings. In order to improve a housing of said type in such a way that a sufficient strength of the housing is given, even with a comparatively small material thickness, and such that also additional measures for cooling can be dispensed with, a plurality of impact dampers that protrude at least from the lateral surface are arranged on said lateral surface.
