System and method for distribution of electrical power

A method of mounting an electrically powered device having power receiving contacts for mounting and powering of the device on a display housing having a mounting wall having a front surface and a rear surface, the method comprising:

• housing the power receiving contacts in a mounting pin projecting from the electrically powered device, the power receiving contacts being protected against electrically conductive manual engagement or contact by the mounting pin;
• mounting one or more power delivery members having power delivery contacts on the rear surface of the mounting wall in a select arrangement;
• forming a series of apertures in the mounting wall that are adapted to receive and retain the mounting pin of the electrically powered device upon receipt;
• arranging the formed apertures on the mounting wall of the housing in an arrangement that is complementary to the select arrangement of the power delivery members mounted on the rear surface such that the mating contacts of the electrically powered device are guided or routed into engagement with the power delivery contacts upon receipt of the pin through a primary aperture formed in the wall;
• and,
• inserting the pin of the electrically powered device into one of the apertures and guiding the mating contacts into engagement with the power delivery contacts during the inserting of the pin.

An electrical power distribution and mounting system, the system comprising:

• a housing comprising a mounting wall having a front side, a rear side and a plurality of apertures arranged in a select pattern,
• a power delivery member mounted on the rear side of the mounting wall, the power delivery member including power delivery contacts and a ground contact aligned with the plurality of apertures in the mounting wall and arranged on the power delivery member in a select arrangement for electrically powering one or more electrically powered devices,
• each electrically powered device including complementary mating contacts projecting from the electrically powered device in an arrangement that is complementary to the select arrangement of the power delivery and ground contacts of the power delivery member,
• each electrically powered device being mountable in a stable position on the front side of the mounting wall such that the mating contacts projecting from the electrically powered device extend through one of the apertures in the mounting wall and engage with a corresponding power delivery contact and ground contact of the power delivery member when or as the electrically powered device is fully mounted in the stable position, the mating contacts projecting from the electrically powered device being housed or covered against electrically conductive contact or engagement with a hand or external object, and,
• wherein the select arrangement of the power delivery contacts and the ground contact of the electrical power delivery member is selected such that the ground contact of the power delivery member engages with a complementary mating contact of the electrically powered device before the power delivery contacts of the power delivery member engage with a complementary mating contact of the electrically powered device during the course of the electrically powered device being mounted on the front side of the mounting wall.

An electrical power distribution and mounting system, the system comprising:

• a housing comprising a mounting wall having a front side, a rear side and a plurality of apertures arranged in a select pattern,
• a power delivery member mounted on the rear side of the mounting wall, the power delivery member including power delivery contacts and a ground contact aligned with the plurality of apertures in the mounting wall and arranged on the power delivery member in a select arrangement for electrically powering one or more electrically powered devices,
• each electrically powered device including complementary mating contacts housed within a pin projecting from and supporting the weight of the electrically powered device on the front side of the mounting wall, the complementary mating contacts being arranged in an arrangement that is complementary to the select arrangement of the power delivery and ground contacts of the power delivery member,
• each electrically powered device being mountable in a stable position on the front side of the mounting wall such that the pin with the mating contacts projecting from the electrically powered device extend through one of the apertures in the mounting wall, the mating contacts engaging with a corresponding power delivery contact and ground contact of the power delivery member when or as the electrically powered device is fully mounted in the stable position,
• wherein the select arrangement of the power delivery contacts and the ground contact of the electrical power delivery member is selected such that the ground contact of the power delivery member engages with a complementary mating contact of the electrically powered device before the power delivery contacts of the power delivery member engage with a complementary mating contact of the electrically powered device during the course of the electrically powered device being mounted on the front side of the mounting wall.
