The connector feature is further characterized by n being included in the first section of the outer (four) electrical contact # including a - not (four) shape that provides an available space adapted to accommodate the front portion of the circuit board. With these features, there is more available surface in the front portion of the board, for example, for conducting, and the front portion of the board is received by the free space of the protrusion. The present invention is of particular interest for cabinet applications in that it is possible to use a connector with a circuit board having a larger size for the same available space. Therefore, a more dense board package can be achieved. Moreover, by providing a portion of the first section of the electrical contact mounted to an outer casing having an asymmetrical shape, it is possible to obtain a connector of reduced height. Thus, in accordance with the present invention, the connector can be mounted over a thicker circuit board within the same available space of a cabinet.

The planarized surface 12 of the electrical contact extends parallel to and is opposite the upper surface of the circuit board 2. Further, the convex (four) of the lower layer is, for example, cut in the same manner as shown in Fig. 3. In accordance with the present invention, it will be appreciated that any other cutting shape of the lowermost portion of the contact member can be grasped as long as the outer casing engaging portion of the contact member has an asymmetrical shape. The shape of the lower layer power contact is substantially the same as the upper power contact, but differs in that the outer casing engagement portion includes an asymmetrical shape. More specifically, the shape of the bottommost portion of the contact portion is to provide a planarized surface 12 that is substantially parallel to the first symmetry. In this example, the planar shape is in cross section. The cylinder faces correspond to a shape that is parallel to the plane of the longitudinal axis of the cylinder. This provides: For example, as shown in Figures 2 and 3, the housing 3 also includes a connector mechanical positioning feature 13 mounted above the circuit board. In this embodiment, the holding features are: positioning arms projecting laterally and rearward from the back surface 3b of the insulative housing 3. Each of the positioning arms 13 has a lower support table _, which is set to 125779.doc 200836416, which is an example for resting on the upper surface of the circuit board 2 when the electrical connector is fixed in place, The positioning arm also includes a holding feature. For example, the retaining features are provided as a series of vertically downwardly extending parallel tabs 15 for retaining complementary apertures and forming complementary retention features 16 provided in the circuit board 2. The outer casing 3 has - located below the lower surface 14 of the lower portion # and at its outer lower edge 17, and has a projection 18 which is formed in a portion from the back (four) to the thickness of the front surface 3a. The projection 18 is located below the lower support surface 14 of the positioning arms 1, 3 and extends vertically to the lower reading surface μ such that the lower edge 17 of the outer casing is shaped like a flange portion 19. In terms of use, for example, when the connector 1 is mounted on the circuit board 2, the flange portion formed by the lower edge of the outer casing abuts the front edge 22 of the circuit board 2 (Fig. 4), the front portion thereof It is accommodated in the gap provided by the protrusion (4). Therefore, more board surface area can be provided on the board 2; this surface area gain is substantially equivalent to the space released by the protrusions 18. Thus, for cabinet applications, the connector of the present invention can be mounted on a circuit board having more surface area available to provide a cabinet configuration. Goods = the asymmetrical shape of the contact provided by the bottom (four) points, the height of the W is possible. The shape feature of the contact member is also: in the provision of a more dense cabinet construction, wherein the circuit board is fixed to a layer on top of =. In fact, the height reduction of the connector can be advantageously converted to a thick circuit board (for example: with more backward conduction). 125779.doc 200836416 As shown in Figure 4, the electric car is transported and stolen 1 installed. Above the circuit board 2, 1 ^ of the first holding feature 15 buds are mated with the complementary holding features 16 of the circuit board. In this figure, only one of the φ power supply contacts 4 and the signal contact 5 are inserted into the corresponding partial I-knife 20 21 of the circuit board 2, respectively. The front side of the outer casing 3 complements the lower support surface 14: the edge 22 of the private circuit board 2 is in contact for better retention. please
