Abstract
Abstract An enhanced electronic card structure includes a circuit board, a top cover board, and a bottom cover board. The circuit board has multiple front front and rear contact points. At least one fixing hole is defined between any two adjacent front contact points. The top cover board has a front edge defined therein multiple gaps, each aligned with one front contact point and corresponding rear contact point. Any two adjacent gaps are separated by a rib, each rib having a bottom face extended thereform a fixing tip aligned with the fixing hole. The bottom cover board has a surface formed thereon multiple fixing joints, each aligned with one fixing tip at the bottom of the rib, so as to make the fixing tip pass through the corresponding fixing hole to be fixed to the corresponding fixing joint.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
186 words
An enhanced electronic card structure comprising: a circuit board having a surface, and multiple front and rear contact points arranged at a front edge of the surface, wherein any one of the rear contact points is arranged at the back of a front contact point, and at least one fixing hole is defined between any two adjacent front contact points; a top cover board arranged on top of the circuit board, and having a front edge defined therein multiple gaps, each gap being aligned with one front contact point and corresponding rear contact point, any two adjacent gaps being separated by a rib, each rib having a bottom face extended therefrom at least one fixing tip which is aligned with the at least one fixing hole; and a bottom cover board arranged below the circuit board, and having a surface formed thereon multiple fixing joints, each fixing joint being aligned with one fixing tip at the bottom of the rib of the top cover board, so as to make the fixing tip pass through the corresponding fixing hole to be fixed to the corresponding fixing joint.
Claim 2
Dependent Claim
186 words
An enhanced electronic card structure comprising: a circuit board having a surface, and multiple front and rear contact points arranged at a front edge of the surface, wherein any one of the rear contact points is arranged at the back of a front contact point, and at least one fixing hole is defined between any two adjacent front contact points; a top cover board arranged on top of the circuit board, and having a front edge defined therein multiple gaps, each gap being aligned with one front contact point and corresponding rear contact point, any two adjacent gaps being separated by a rib, each rib having a bottom face extended therefrom at least one fixing tip which is aligned with the at least one fixing hole; and a bottom cover board arranged below the circuit board, and having a surface formed thereon multiple fixing joints, each fixing joint being aligned with one fixing tip at the bottom of the rib of the top cover board, so as to make the fixing tip pass through the corresponding fixing hole to be fixed to the corresponding fixing joint.
