Card edge connector

A card edge connector adapted to establish electrical connection between a first circuit board and a second circuit board, said card edge connector comprising:

• an insulating housing having an elongated body, one face of said body which is along a longer side thereof being formed with an insert groove for insertion of one end of the second circuit board thereinto, said body being formed with a plurality of slots extending through a shorter side of said body, two ends of said body along the longer side thereof projecting in the same direction to form respective support arms;
• a plurality of terminals respectively disposed in said slots and having contact ends inserted into said insert groove to electrically contact the second circuit board, and coupling ends to be electrically connected to the first circuit board;
• a pair of metal support members which are respectively and detachably secured on said support arms to limit rotation of each of said support arms in an imaginary plane;
• a pair of interference devices which are formed from an insulating material and which are respectively and integrally formed on adjacent sides of said support arms such that when the second circuit board is positioned in said card edge connector, each of said interference devices generating interference with the second circuit board and serving as a point of application of an external force to relieve the second circuit board of the interference.

A card edge connector adapted to establish electrical connection between a first circuit board and a second circuit board, two opposite sides of the second circuit board respectively having depressed portions, said card edge connector comprising:

• an insulating housing having an elongated body, one face of a longer side of said body being formed with an insert groove for insertion of the second circuit board, said body being formed with a plurality of slots extending through a shorter side of said body, two ends of the longer side of said body having support arms projecting therefrom in the same direction;
• a plurality of terminals respectively disposed in said slots, each of said terminals having a contact end disposed to electrically contact an end of the second circuit board that is inserted into said insert groove;
• and a coupling end disposed to electrically connect with the first circuit board;
• a pair of metal support members which are respectively and detachably secured on said support arms so as to limit rotation of each of said support arms in an imaginary plane;
• and
• a pair of interference devices which are respectively and integrally formed on adjacent sides of said support arms such that when the second circuit board is positioned in said card edge connector, each of said interference devices generating interference with a respective one of the depressed portions of the second circuit board, a force being exertable directly on each of said interference devices to relieve the second circuit board of the interference, each of said interference devices projecting from the surface of the respective one of said support arms on which it is formed.
