Abstract
Abstract A SIM card connector (2) comprises a housing (4) and two sets (8, 10) of terminals (6). The terminal sets (8, 10) are held together by overmoulded support portions (18) which are then mounted to receiving cavities (44) of the housing (4). The terminals (6) are interleaved and angled for a compact disposition for electrical connection to parallel rows of aligned SIM card contact pads. Sides (52, 54) of the outer periphery (50) of the housing (4) are inclined at the same angle as the terminals (6) such than a small connector surface are is provided. The principal advantage is therefore minimum surface area requirements when mounted to a PC Board. Further advantages are the few number of parts, and simple, reliable and cost-effective design.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
150 words
A SIM card connector for mounting on a PCB comprising a housing bounded by a periphery comprising opposed sides extending between opposed ends, and a plurality of terminals, each terminal comprising a longitudinal spring beam section and a contact protrusion, the terminals being arranged in a row along one of the ends at least, and the spring beam sections extending therefrom at an angle less than 90° with respect to the row such that the contact protrusions thereof make electrical contact with two parallel rows of aligned SIM card circuit pads, wherein the terminals are disposed in two rows, a first row extending from one end of the connector, and a second row extending from the other opposed end, the terminals of both rows being interleaved with each other, and wherein the sides are substantially parallel to the angled spring beam sections for a minimal usage of PCB surface area.
Claim 2
Dependent Claim
150 words
A SIM card connector for mounting on a PCB comprising a housing bounded by a periphery comprising opposed sides extending between opposed ends, and a plurality of terminals, each terminal comprising a longitudinal spring beam section and a contact protrusion, the terminals being arranged in a row along one of the ends at least, and the spring beam sections extending therefrom at an angle less than 90° with respect to the row such that the contact protrusions thereof make electrical contact with two parallel rows of aligned SIM card circuit pads, wherein the terminals are disposed in two rows, a first row extending from one end of the connector, and a second row extending from the other opposed end, the terminals of both rows being interleaved with each other, and wherein the sides are substantially parallel to the angled spring beam sections for a minimal usage of PCB surface area.
Claim 3
Dependent Claim
25 words
The connector of claim 1 wherein the terminals of each row are rigidly fixed together by an overmoulded support portion, thereby forming a terminal set.
Claim 4
Dependent Claim
12 words
The connector of claim 2 wherein the two terminal sets are identical.
Claim 5
Dependent Claim
30 words
The connector of claim 2 wherein the housing has a pair of cavities, each proximate one of the corresponding connector ends for receiving and securely holding the support portions therein.
Claim 6
Dependent Claim
54 words
The connector of claim 1 wherein the housing has an upper SIM card receiving surface beyond which the contact protrusions project for contacting a SIM card positioned substantially against the surface, the housing further comprising a ledge adjacent the periphery and offset from the surface for receiving the edge of a panel cutout thereagainst.
Claim 7
Dependent Claim
29 words
The connector of claim 1 wherein the connector ends are substantially parallel to the rows of contact protrusions such that the periphery is substantially the shape of a rhombus.
