The electrical contacts are configured to be connected to a conductor of an electrical cable and include two sides, each side having a discontinuous contact positioning feature. Optionally, the inner housing includes a substantially hollow center wall having a plurality of wall reinforcement ribs. A terminated cable assembly includes the connector for electrical cables and an electrical cable electrically connected to the connector. ## Claims ### Claim 1 A connector for electrical cables comprising: a tubular housing of electrically conductive material having inner walls defining an opening and first and second opposed open ends; an inner housing of electrically insulating material adapted to be inserted into the tubular housing from at least one of the open ends thereof, the inner housing comprising inner spaces configured to receive electrical contacts in fixed relative positions; and a plurality of electrical contacts positioned in the inner housing and configured to be connected to a conductor of an electrical cable, the electrical contacts including a plug-in portion, a connection portion, and a contact positioning portion positioned therebetween, the contact positioning portion comprising a discontinuous contact positioning feature, wherein the electrical contacts have a generally u-shaped form including a substantially planar bottom wall and two side walls extending from the bottom wall, wherein the discontinuous contact positioning feature includes first and second sections laterally extending from the bottom wall to a substantially identical height, and wherein the first and second sections include external edges that cooperate with the inner housing to prevent the electrical contact from moving towards the first and second opposed open ends, respectively; and wherein the inner housing further comprises a substantially hollow center wall having a plurality of wall portions and a plurality of wall reinforcement ribs having a thickness substantially the same as a thickness of the wall portions. ### Claim 2 (depends on 1) The connector of claim 1, wherein the discontinuous contact positioning feature comprises one or more apertures. ### Claim 3 (depends on 1) The connector of claim 1, wherein the inner housing is a two part housing. ### Claim 4 (depends on 1) The connector of claim 1, wherein the outer dimensions of the inner housing substantially correspond to the inner dimensions of the tubular housing. ### Claim 5 (depends on 1) The connector of claim 1, wherein the inner housing further comprises a stop at one end configured to engage one of the ends of the tubular housing. ### Claim 6 (depends on 1) The connector of claim 1, wherein the tubular housing comprises one or more external ground contacts. ### Claim 7 (depends on 1) The connector of claim 1, wherein the tubular housing comprises an opening configured to enable electrically connecting a shield of the electrical cable to the tubular housing. ### Claim 8 (depends on 1) The connector of claim 1, wherein the discontinuous contact positioning feature comprises a recess extending to the bottom wall. ### Claim 9 A terminated cable assembly comprising: a connector for electrical cables comprising: a tubular housing of electrically conductive material having inner walls defining an opening and first and second opposed open ends; an inner housing of electrically insulating material adapted to be inserted into the tubular housing from at least one of the open ends thereof, the inner housing comprising inner spaces configured to receive electrical contacts in fixed relative positions; and a plurality of electrical contacts positioned in the inner housing and configured to be connected to a conductor of an electrical cable, the electrical contacts including a plug-in portion, a connection portion, and a contact positioning portion positioned therebetween, the contact positioning portion comprising a discontinuous contact positioning feature, wherein the electrical contacts have a generally u-shaped form including a substantially planar bottom wall and two side walls extending from the bottom wall, wherein the discontinuous contact positioning feature includes first and second sections laterally extending from the bottom wall to a substantially identical height, and wherein the first and second sections include external edges that cooperate with the inner housing to prevent the electrical contact from moving towards the first and second opposed open ends, respectively; and the electrical cable electrically connected to the connector; and wherein the inner housing further comprises a substantially hollow center wall having a plurality of wall portions and a plurality of wall reinforcement ribs having a thickness substantially the same as a thickness of the wall portions. ### Claim 10 (depends on 9) The terminated cable assembly of claim 9, wherein the discontinuous contact positioning feature comprises one or more apertures. ### Claim 11 (depends on 9) The terminated cable assembly of claim 9, wherein the electrical cable is one of a coaxial cable, a twinaxial cable, and a twisted pair cable. ### Claim 12 (depends on 9) The terminated cable assembly of claim 9, wherein the discontinuous contact positioning feature comprises a recess extending to the bottom wall.
