Connector assembly and electrical connection assembly

A connector assembly, comprising:

• an installation seat including:
• an installation plate;
• a convex portion formed on a top surface of the installation plate;
• a housing portion formed on a bottom surface of the installation plate;
• a pair of first installation holes;
• and
• a second installation hole that runs through the convex portion, the installation plate and is communicated with an inner cavity of the housing portion;
• a pair of first connectors respectively detachably inserted into the first installation holes, each of the first connectors has a power terminal;
• and
• a second connector detachably inserted into the second installation hole, the second connector has a signal terminal and a grounding terminal, the second connector includes:
• a second shielding shell having an installation port and a cable port;
• a second insulator having a portion inserted into the second shielding shell through the installation port, the signal terminal and the grounding terminal are provided in the second insulator, the second insulator has a flange part fixed on the convex portion, another part of the second insulator passes through the second installation hole and extends into the inner cavity of the housing portion, the housing portion is mateable with a mating housing portion of a mating installation seat;
• a signal cable having an end extending into the second shielding shell through the cable port and electrically connected to the signal terminal;
• and
• a grounding cable having an end extending into the second shielding shell through the cable port and electrically connected to the grounding terminal.

A connector assembly, comprising:

• an installation seat having a pair of first installation holes and a second installation hole;
• a pair of first connectors respectively detachably inserted into the first installation holes, each of the first connectors has a power terminal;
• a second connector detachably inserted into the second installation hole, the second connector has a signal terminal and a grounding terminal;
• a fixed bracket;
• and
• an elastic assembly arranged between the installation seat and the fixed bracket, the installation seat is floatably installed on the fixed bracket through the elastic assembly, the installation seat can float relative to the fixed bracket in a mating direction of the connector assembly and a mating connector assembly and in a direction perpendicular to the mating direction.

An electrical connection assembly, comprising:

• a connector assembly includes an installation seat having a pair of first installation holes and a second installation hole, a pair of first connectors respectively detachably inserted into the first installation holes, each of the first connectors has a power terminal, and a second connector detachably inserted into the second installation hole, the second connector has a signal terminal and a grounding terminal;
• and
• a mating connector assembly mated with the connector assembly, the mating connector assembly includes a mating installation seat mated with the installation seat, a first mating connector installed on the mating installation seat and mated with the first connector, and a second mating connector on the mating installation seat and mated with the second connector, the installation seat includes an installation plate and a circumferential wall formed on a bottom surface of the installation plate, the mating installation seat includes a fixed plate and a mating circumferential wall formed on the fixed plate, the circumferential wall is mated with the mating circumferential wall to define a receiving cavity, a plurality of mating portions of the first connector and the first mating connector as well as a plurality of mating portions of the second connector and the second mating connector are accommodated in the receiving cavity defined by the circumferential wall and the mating circumferential wall.
