Abstract
Abstract The four corners of the pressure section (20) of the contact (10) punched out of a metal sheet are rounded off to form an oval surface (22). The lower portion (38) of the contact mounting opening (32) of the housing (30) is made of the same configuration as the pressure section (20). Since the dimensions of cross section of the lower portion (38) are made smaller than the corresponding dimensions of the pressure section (20), a tight joining is formed around the pressure section (20).

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
103 words
An electrical connector comprising an insulating housing having at least one opening; a contact pressed into said opening that is generally flat by stamping a metal plate and includes a soldering tail section, a pressure section with corners being rounded off to provide a generally oval cross section, a retention section and a connection section; and said opening in the housing being profiled to have a slightly smaller dimension than said pressure section at the end closer to the soldering tail section, thereby substantially eliminating any gap between said opening and said pressure section when the contact is fully inserted into said opening.
Claim 2
Dependent Claim
103 words
An electrical connector comprising an insulating housing having at least one opening; a contact pressed into said opening that is generally flat by stamping a metal plate and includes a soldering tail section, a pressure section with corners being rounded off to provide a generally oval cross section, a retention section and a connection section; and said opening in the housing being profiled to have a slightly smaller dimension than said pressure section at the end closer to the soldering tail section, thereby substantially eliminating any gap between said opening and said pressure section when the contact is fully inserted into said opening.
Claim 3
Dependent Claim
23 words
An electrical connector of claim 1, wherein said retention section of the contact is formed with engaging bosses and stoppers at both sides.
Claim 4
Dependent Claim
22 words
An electrical connector of claim 1, wherein said soldering tail section of the contact is narrower and thinner than said pressure section.
