Abstract
Abstract A frame member is bonded on a base plate having a plurality of electrical contacts thereon. The frame member includes a plurality of apertures corresponding to the electrical contacts. Bonding means bonding the frame member on the base plate is formed by a waterproof double faced bonding member including a waterproof sheet and waterproof bonding agent applied to both sides of the sheet, the double faced bonding member separates the electrical contacts from each other to prevent accidential conduction between the adjacent electrical contacts due to a water drop.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
109 words
An electrical connecting terminal comprising: a substrate; a plurality of electrical contacts disposed on said substrate; a frame member having a plurality of apertures corresponding to said electrical contacts, and having wall portions in enclosing registry within individual apertures; and waterproof double faced bonding sheet means having a plurality of apertures corresponding to said apertures of said frame member and adhesive sheet portions corresponding to said wall portions so as to individually enclose said respective apertures, said sheet portions bonding said frame member to said substrate so that said wall portions and said sheet portions individually surround each electrical contact thereby providing a water resistant separation between said contacts.
Claim 2
Dependent Claim
109 words
An electrical connecting terminal comprising: a substrate; a plurality of electrical contacts disposed on said substrate; a frame member having a plurality of apertures corresponding to said electrical contacts, and having wall portions in enclosing registry within individual apertures; and waterproof double faced bonding sheet means having a plurality of apertures corresponding to said apertures of said frame member and adhesive sheet portions corresponding to said wall portions so as to individually enclose said respective apertures, said sheet portions bonding said frame member to said substrate so that said wall portions and said sheet portions individually surround each electrical contact thereby providing a water resistant separation between said contacts.
Claim 3
Dependent Claim
35 words
An electrical connecting terminal as set forth in claim 1, wherein said waterproof double faced bonding sheet means includes a waterproof sheet and a waterproof bonding agent applied to both sides of said waterproof sheet.
Claim 4
Dependent Claim
28 words
An electrical connecting terminal as set forth in claim 1, wherein said waterproof double faced bonding sheet means is an adhesive sheet made of a waterproof bonding material.
Claim 5
Dependent Claim
30 words
An electrical connecting terminal as set forth in claim 3, wherein said adhesive sheet is thermosensitive so as to be bonded to said substrate and said frame member when heated.
Claim 6
Dependent Claim
35 words
An electrical connecting terminal as set forth in claim 1, wherein said substrate is a flexible printed circuit board having printed patterns, said electrical contacts being constituted by a portion of the respective printed patterns.
Claim 7
Dependent Claim
25 words
An electrical connecting terminal as set forth in claim 5, further comprising an electrically insulative coverlay covering said printed patterns except for said electrical contacts.
Claim 8
Dependent Claim
112 words
An electrical connecting terminal comprising: a substrate; a plurality of electrical contacts disposed on said substrate; a frame member having a plurality of apertures corresponding to said electrical contacts and having wall portions in enclosing registry with the individual apertures; and water-resistant double faced bonding sheet means having a plurality of apertures corresponding to said apertures of said frame member and adhesive sheet portions corresponding to said wall portions, so as to individually enclose said respective apertures, said sheet portions bonding said wall portions to said substrate so that said sheet portions surround each individual electrical contact thereby resisting the passage of water through gaps between said substrate and said wall portions.
Claim 9
Dependent Claim
112 words
An electrical connecting terminal comprising: a substrate; a plurality of electrical contacts disposed on said substrate; a frame member having a plurality of apertures corresponding to said electrical contacts and having wall portions in enclosing registry with the individual apertures; and water-resistant double faced bonding sheet means having a plurality of apertures corresponding to said apertures of said frame member and adhesive sheet portions corresponding to said wall portions, so as to individually enclose said respective apertures, said sheet portions bonding said wall portions to said substrate so that said sheet portions surround each individual electrical contact thereby resisting the passage of water through gaps between said substrate and said wall portions.
Claim 10
Dependent Claim
