An electrical connection assembly includes a main body and a spring. One end of the main body is configured to be in contact with a device under test. The spring is sleeved around the main body. Two ends of the spring are respectively defined as a first end and a second end. The first end is abutted against a limiting protrusion, and a concealed section of the main body is correspondingly arranged inside of the spring. The spring has a first tightly-coiled section, an elastic section, and a second tightly-coiled section in sequence from the first end to the second end. A pitch of the spring within the elastic section is greater than a pitch of the spring within the first tightly-coiled section, and the pitch of the spring within the elastic section is greater than a pitch of the spring within the second tightly-coiled section.
