An opening is provided in the front wall for receiving a plug inside the terminal housing, opposing side walls, and a top wall and an opposing bottom wall. The bottom wall has an inner surface facing the inside of the terminal housing and an outer surface facing away from the inside of the terminal housing. The outer surface (can have at least two retention pins projecting from the outer surface for being inserted into corresponding holes in the PCB. A first retention pin can be positioned on the outer surface so as to be arranged asymmetrically with respect to a second retention pin. ## Claims ### Claim at position 1 1-10. (canceled) ### Claim 11 An electrical connector mountable to a substrate, the electrical connector comprising: a terminal housing having a front wall and an opposing back wall, wherein an opening is provided in the front wall to receive a plug inside the terminal housing, the terminal housing also having opposing side walls, a top wall and an opposing bottom wall, wherein the bottom wall has an inner surface facing an inside of the terminal housing and an outer surface facing away from the inside of the terminal housing, the outer surface being provided with at least two retention pins projecting from the outer surface to be insertable into corresponding holes in the substrate; the at least two retention pins comprising a first retention pin and a second retention pin, the first retention pin positioned on the outer surface so as to be arranged asymmetrically with respect to the second retention pin. ### Claim 12 (depends on 11) The electrical connector of claim 11, wherein the substrate is a PCB. ### Claim 13 (depends on 11) The electrical connector of claim 11, wherein the asymmetrical arrangement of the first retention pin and the second retention pin is an axial asymmetry about a first axial symmetry axis running in a longitudinal direction of the terminal housing from the front wall to the back wall. ### Claim 14 (depends on 13) The electrical connector of claim 13, wherein the first axial symmetry axis runs through the center of the terminal housing. ### Claim 15 (depends on 11) The electrical connector of claim 11, wherein the asymmetrical arrangement of the first retention pin and the second retention pin is an axial asymmetry about an axial symmetry axis running from a first side wall of the two opposing side walls to the second side wall of the opposing side walls. ### Claim 16 (depends on 15) The electrical connector of claim 15, wherein the axial symmetry axis runs through the center of the terminal housing. ### Claim 17 (depends on 11) The electrical connector of claim 11, wherein the at least two retention pins are arranged at a bottom surface of the terminal housing so as to not be symmetrical about a rotation axis extending in a longitudinal direction of the terminal housing from the front wall to the back wall. ### Claim 18 (depends on 11) The electrical connector of claim 11, wherein the at least two retention pins are provided on a bottom surface of the terminal housing. ### Claim 19 A Printed Circuit Board (PCB) comprising: a board having holes for receiving at least two electrical connectors including a first electrical connector and a second electrical connector, each of the electrical connectors comprising: a terminal housing having a front wall and an opposing back wall, wherein an opening is provided in the front wall to receive a plug inside the terminal housing, the terminal housing also having opposing side walls, a top wall and an opposing bottom wall, wherein the bottom wall has an inner surface facing an inside of the terminal housing and an outer surface facing away from the inside of the terminal housing, the outer surface being provided with at least two retention pins projecting from the outer surface to be insertable into corresponding holes in the substrate; the at least two retention pins comprising a first retention pin and a second retention pin, the first retention pin positioned on the outer surface so as to be arranged asymmetrically with respect to the second retention pin; and wherein the first electrical connector is arranged on an upper side of the PCB and the second electrical connector is arranged on an opposing lower side of the PCB at a corresponding location of the first electrical connector. ### Claim 20 (depends on 19) The PCB of claim 19, wherein the first electrical connector and the second electrical connector are arranged on opposing sides at the corresponding location of the PCB that are identical with respect to positions of the retention pins provided on their respective bottom surfaces. ### Claim 21 (depends on 20) The PCB of claim 20, wherein the first electrical connector and the second electrical connector are fixed to the PCB only by means of the retention pins. ### Claim 22 (depends on 19) The PCB of claim 19, wherein the first electrical connector and the second electrical connector are fixed to the PCB only by means of the retention pins.
