Abstract
Abstract An improved connecting terminal for an electromagnetic shield is provided for use with a printed circuit board. The printed circuit board is contained in a shielded casing having shielding walls to define compartments. The connecting terminal makes an electric connection between the ground pattern, the shielded inside and shielding walls of the shielded casing, thereby preventing an electromagnetic field from interfering with surrounding electric circuits. The connecting terminal comprises an elongated base strip having an undersurface to be soldered to a selected portion of the ground pattern and a pair of inwardly directed contact arms integrally connected to the opposite ends of the elongated base strip. Each contact arm makes contact with the shielded inside and shielding walls of the casing.

Claims Analysis
Total Claims: 14
Claim 1
Independent Claim
86 words
A connecting terminal (1) for connecting an electromagnetic shield (12, 13) to a ground pattern (16) formed on a printed circuit board (15) comprising an elongated base strip (2) with an undersurface to be soldered to a selected portion of the ground pattern (16) and a pair of contact arms (3) each having a contact (4) for contacting the electromagnetic shield (12, 13), characterized in that: said contact arms (3) are each inwardly directed and integrally connected to opposite ends of the elongated base strip (2).
Claim 2
Dependent Claim
30 words
A connecting terminal according to claim 1 characterized in that: a shape retainer (5) occupies the space (S) defined between the elongated base strip (2) and the contact arms (3).
Claim 3
Dependent Claim
53 words
A connecting terminal according to claim 1 characterized in that: a top surface of the elongated base strip has a generally planar portion (6) to which a negative pressure may be applied to suckingly hold the connecting terminal (1) and apply the connecting terminal to the selected portion of the ground pattern (16).
Claim 4
Dependent Claim
53 words
A connecting terminal according to claim 2 characterized in that: the top surface of the shape retainer (5) has a generally planar portion (6') to which a negative pressure may be applied to suckingly hold the connecting terminal (1) and apply the connecting terminal to a selected portion of the ground pattern (16).
Claim 5
Dependent Claim
53 words
A connecting terminal according to claim 1 characterized in that: said printed circuit board (15) is contained in a shielded casing (11) including shielding walls (13) defining compartments, said connecting terminal (1) being designed to make electric connections between the ground pattern (16), and the shielding walls (13) of the shielded casing (11).
Claim 6
Dependent Claim
18 words
A connecting terminal according to claim 1 characterized in that: the contact arms (3) converge toward each other.
Claim 7
Dependent Claim
16 words
A connecting terminal according to claim 1 characterized in that: the contact arms (3) are inclined.
Claim 8
Dependent Claim
34 words
