The receptacle connector may include contacts within openings in the connector housing. The openings may receive at least an 8 mm contact from the plug connector. The receptacle may have an insulative pin within the opening to make the receptacle connector touch proof. The contacts of the plug connector may include an opening to receive the insulative pin. Reduced mating force may be achieved with polarizing features on structures associated with different contacts in the connector system oriented differently such that any force generated by engagement of one set of polarizing features is offset by others of the polarizing features. A cable assembly may be flexible as a result of a junction block connecting a large diameter cable bunder to multiple smaller diameter cables. ## Claims ### Claim 1 A receptacle connector, comprising: a housing having tubular protrusions, the tubular protrusions having receptacle contacts at inner sides of the tubular protrusions, the tubular protrusions extending along a plugging and unplugging direction of the receptacle connector; and insulating pins extending within the tubular protrusions along the plugging and unplugging direction of the receptacle connector. ### Claim 2 (depends on 1) The receptacle connector of claim 1, wherein the insulating pins protrude from an interior of the tubular protrusions to an exterior of the tubular protrusions. ### Claim 3 (depends on 1) The receptacle connector of claim 1, wherein the insulating pins are attached to the housing within the tubular protrusions. ### Claim 4 (depends on 3) The receptacle connector of claim 3, wherein the insulating pins are attached to the housing at proximal ends of the tubular protrusions. ### Claim 5 (depends on 3) The receptacle connector of claim 3, wherein the receptacle contacts includes inner protrusions extending within the tubular protrusions along the plugging and unplugging direction of the receptacle connector, and the insulating pins are attached to distal ends of the inner protrusions. ### Claim 6 (depends on 5) The receptacle connector of claim 5, wherein the inner protrusions are conductive. ### Claim 7 (depends on 1) The receptacle connector of claim 1, wherein the insulating pins are positioned at central portions of the tubular protrusions. ### Claim 8 (depends on 1) The receptacle connector of claim 1, wherein the insulating pins are configured to prevent a person from contacting the receptacle contacts. ### Claim 9 (depends on 1) The receptacle connector of claim 1, further comprising at least one securing structure configured to attach the receptacle connector to a plug connector. ### Claim 10 (depends on 9) The receptacle connector of claim 9, wherein the at least one securing structure comprises a rotating latch. ### Claim 11 (depends on 1) The receptacle connector of claim 1, wherein the tubular protrusions are arranged in at least one row. ### Claim 12 (depends on 11) The receptacle connector of claim 11, wherein the tubular protrusions are arranged in a single row and a quantity of tubular protrusions arranged in the single row is five. ### Claim 13 (depends on 11) The receptacle connector of claim 11, wherein the tubular protrusions are arranged in a first row and a second row, a quantity of tubular protrusions arranged in the first row is four, and a quantity of the tubular protrusions arranged in the second row is three. ### Claim 14 (depends on 1) A cable assembly comprising the receptacle connector of claim 1, the cable assembly further comprising: a cable overmold at a proximal end of the housing; cables electrically connected to the receptacle contacts, the cables extending from a proximal end of the cable overmold, wherein the cables are arranged in a single row; and a junction block attached to proximal ends of the cables, the junction block being configured to connect the cables to a cable bundle. ### Claim 15 (depends on 1) The receptacle connector of claim 1, wherein the receptacle connector is a right-angle connector. ### Claim 16 A plug connector, comprising: a housing including recesses, the recesses having plug contacts extending along a plugging and unplugging direction of the plug connector, wherein the plug contacts have holes extending along the plugging and unplugging direction of the plug connector, wherein the holes are configured to accommodate insulating pins of a receptacle connector. ### Claim 17 (depends on 16) The plug connector of claim 16, further comprising insulating caps attached to distal ends of the plug contacts. ### Claim 18 (depends on 17) The plug connector of claim 17, wherein the insulating caps have holes to accommodate the insulating pins. ### Claim 19 (depends on 16) The plug connector of claim 16, wherein the plug contacts have an external cross-section that is circular. ### Claim 20 (depends on 19) The plug connector of claim 19, wherein an outer diameter of the plug contacts is approximately eight millimeters. ### Claim at position 21 -32. (canceled) ### Claim 33 A cable assembly, comprising: a connector, including: a housing having a plurality of openings extending along a plugging and unplugging direction of the connector; a plurality of contacts within respective openings of the plurality of openings; and insulating structures within the respective openings so as to make the connector touch proof; a cable bundle comprising a plurality of cables electrically coupled to the plurality of contacts, respectively; and a junction block comprising a plurality of conductive members attached to the plurality of cables. ### Claim 34 (depends on 33) The cable assembly of claim 33, further comprising cables electrically connected to the plurality of contacts, the cables extending from a proximal end of the junction block, wherein the cables are arranged in a single row. ### Claim 35 (canceled) ### Claim 36 (depends on 33) The cable assembly of claim 33, wherein: the junction block is configured such that at least some of the plurality of cables are each coupled to multiple contacts of the plurality of contacts.
