Claim 0:
1. An electrical connector, comprising:
an insulating body defining a first receiving space and a second receiving space;
a first installation module, the first installation module being at least partially installed in the first receiving space, the first installation module comprising a first internal circuit board and a first terminal adapter block installed with the first internal circuit board; and
a second installation module, the second installation module being at least partially installed in the second receiving space, the second installation module comprising a second internal circuit board and a second terminal adapter block installed with the second internal circuit board;
wherein the first installation module and the second installation module are different; wherein the first internal circuit board and the first terminal adapter block comprise first fool-proof portions mating with each other, the second internal circuit board and the second terminal adapter block comprise second fool-proof portions mating with each other, and the first fool-proof portions are different from the second fool-proof portions, so as to prevent the first terminal adapter block from being incorrectly connected to the second internal circuit board, and prevent the second terminal adapter block from being incorrectly connected to the first internal circuit board; and
wherein each of the first internal circuit board and the second internal circuit board comprises a first sub-circuit board and a second sub-circuit board; the first sub-circuit board of the first installation module and the second sub-circuit board of first installation module are disposed face to face with each other; the first sub-circuit board of the second installation module and the second sub-circuit board of second installation module are disposed face to face with each other;
the first sub-circuit board of the first installation module is prevented from being incorrectly assembled to the second installation module as the first sub-circuit board of the second installation module;
the second sub-circuit board of the first installation module is prevented from being incorrectly assembled to the second installation module as the second sub-circuit board of the second installation module;
the first sub-circuit board of the second installation module is prevented from being incorrectly assembled to the first installation module as the first sub-circuit board of the first installation module; and
the second sub-circuit board of the second installation module is prevented from being incorrectly assembled to the first installation module as the second sub-circuit board of the first installation module.
