Quick installation connector and lamp assembly

A installation connector, comprising:

• a housing, the housing having an interior space, and a through hole being provided on the housing;
• a mounting bracket, the mounting bracket comprising a plate-like component, a part of the plate-like component extending into the interior space of the housing through the through hole, and the other part of the plate-like component being located outside the housing;
• at least one fixed component, the fixed component being fixed in the interior space of the housing;
• at least one spring, a first end of the spring being fixed to a corresponding fixed component, a second end of the spring opposite to the first end being fixed to the part of the plate-like component located in the interior space, and an extension and compression direction of the spring being parallel to the plate-like component,
• wherein the plate-like component is provided with a through channel penetrating the plate-like component in a direction perpendicular thereto, the through channel has a first segment extending parallel to the extension and compression direction of the spring and a second segment intersecting the first segment, the first segment has a first end for abutting against a fixed screw fixed on a surface to be mounted and a second end opposite to the first end of the first segment, the second segment has a first end for communicating with the second end of the first segment and a second end for penetrating through an edge of the plate-like component to communicate with the outside,
• wherein the mounting bracket is configured to be able to perform translational movement between a rest position, an alignment position and an assembly position through the through hole along the extension and compression direction of the spring, wherein in the rest position, the spring is in a natural state;
• in the alignment position, the second segment is aligned with the fixed screw such that the fixed screw can enter the first segment via the second segment;
• and in the assembly position, the fixed screw abuts against the first end of the first segment.
