A spring is configured for engaging the pin contact and includes a plurality of spring fingers positioned for forming a bore with the spring fingers bent radially inwardly and configured for securing a pin in engagement with the body. A sleeve is configured for engaging the body to overlie the spring. Indentations are formed in the body at discrete positions around the body and extend radially inwardly into the pin section. The spring includes tongues extending radially inwardly and configured for extending into the indentations for securing the spring with the body. ## Claims ### Claim 1 An electrical connector contact comprising: a body having a conductor section for receiving a conductor and a pin section for receiving a male pin contact; a spring configured for engaging the pin section and including a plurality of spring fingers positioned around the pin section for forming a bore, the spring fingers flexing radially inwardly for engaging a pin contact in engagement with the body; a sleeve configured for engaging the body to overlie the spring; the body including a plurality of discrete indentations formed at positions around the body and extending radially into the body; the spring including a plurality of features extending radially inwardly in the bore and into the indentations for securing the spring with the body. ### Claim 2 (depends on 1) The electrical connector contact of claim 1 wherein the spring includes a base section and the spring fingers extending forwardly from the base section, the features extending forwardly from the base section for extending into the indentations. ### Claim 3 (depends on 1) The electrical connector contact of claim 1 wherein the spring includes a base section and the spring fingers extending forwardly with from the base section, the features extending rearwardly from the base section for extending into the indentations. ### Claim 4 (depends on 1) The electrical connector contact of claim 1 wherein the sleeve is configured for engaging a portion of the spring when it engages the body. ### Claim 5 (depends on 1) The electrical connector contact of claim 1 wherein the spring includes at least one spring finger having an asymmetrical shape with a wider base and more narrow tip. ### Claim 6 (depends on 1) The electrical connector contact of claim 1 further comprising a collar positioned rearwardly on the body from the pin section, the sleeve engaging the body and abutting against the collar. ### Claim 7 (depends on 1) The electrical connector contact of claim 1 wherein the sleeve extends over both ends of the spring. ### Claim 8 (depends on 1) The electrical connector contact of claim 1 wherein the body further includes a first step section positioned rearwardly of the pin section, the sleeve configured for engaging the first step section to overlie the spring. ### Claim 9 (depends on 8) The electrical connector contact of claim 8 wherein the body further includes a second step section positioned forwardly of the first step section, the second step section having an outer diameter smaller than the outer diameter of the first step section for providing clearance between the sleeve and spring. ### Claim 10 An electrical connector contact comprising: a body having a conductor section for receiving a conductor and a section for receiving a male pin contact; a spring configured for engaging the body and including a plurality of spring fingers positioned around the body for forming a bore, the spring fingers flexing radially inwardly for securing a pin contact in engagement with the body; a sleeve configured for engaging the body to overlie the spring; the body including a plurality of indentations formed in the body and extending radially inwardly in the body at positions around the body; the spring including a plurality of features extending radially inwardly in the spring and extending forwardly toward the spring fingers for engaging the respective indentations for securing the spring with the body. ### Claim 11 (depends on 10) The electrical connector contact of claim 10 wherein the sleeve is configured for engaging a portion of the spring when it engages the body. ### Claim 12 (depends on 10) The electrical connector contact of claim 10 wherein the sleeve engages at least one of the features of the spring for pushing the feature into a respective indentation. ### Claim 13 (depends on 10) The electrical connector contact of claim 10 wherein the body further includes a first step section and a second step section having a smaller outer diameter than the outer diameter of the first step section for providing clearance, the sleeve configured for engaging the first step section to secure the sleeve with the body. ### Claim 14 (depends on 10) The electrical connector contact of claim 10 wherein the spring includes at least one spring finger having an asymmetrical shape with a wider base and more narrow tip. ### Claim 15 (depends on 10) The electrical connector contact of claim 10 wherein the sleeve extends over both ends of the spring. ### Claim 16 An electrical connector contact comprising: a body configured for receiving a conductor and for receiving a pin contact; a spring configured for engaging the body and including a plurality of spring fingers positioned for forming a bore, the spring fingers flexing radially inwardly for engaging a pin contact; a sleeve configured for engaging the body to overlie the spring; the spring including a plurality of tongues extending radially inwardly in the spring for engaging the body for securing the spring with the body; the sleeve configured for engaging the plurality of tongues of the spring and pushing on the tongues for engagement with the body for securing the spring and providing electrical connection between the body and spring. ### Claim 17 (depends on 16) The electrical connector contact of claim 16 wherein the body includes a plurality of discrete indentations formed in the body and extending radially inwardly in the body at positions around the body; the sleeve pushing the tongues into engagement with the discrete indentations for securing the spring. ### Claim 18 (depends on 16) The electrical connector contact of claim 16 wherein the spring includes a base section and the spring fingers extending forwardly from the base section, the plurality of tongues extending forwardly from the base section for engaging the body. ### Claim 19 (depends on 16) The electrical connector contact of claim 16 wherein the spring includes a base section and the spring fingers extending forwardly from the base section, the plurality of tongues extending rearwardly from the base section for engaging the body.
