Abstract

An electrical connector is disclosed for terminating coaxial cable and mating with a multi-pin array, having at least one signal pin and the rest ground pins and being mounted in a circuit board or the like. The connector has a housing carrying at least one terminal mounted to receive the signal wire of the cable and engage a respective signal pin of the array, and a pair of mating metal shells enclosing the housing, engaging the shielding of the cable, and, upon mating of the connector with the array, contacting the respective ground pins while allowing clear entry of the signal pin to engage the signal terminal.

Claims

1. An electrical connector for making an interconnection between a coaxial cable and an array of pin terminals fixedly mounted in a circuit board or the like, one pin terminal of said array being a signal pin and the remaining pin terminals being ground pins, said connector having a housing with at least one terminal mounted therein and adopted to engage a signal conductor of said coaxial cable and to detachably mate with the signal pin terminal of said array, a pair of mating metal shells enclosing the connector, and means crimping the shielding of said cable to said shells characterized by arms integral with each respective shell member and extending forwardly of the connector, flanges on the free ends of the arms extending transversely thereto to define a plane in front of the mating front end of the connector, a plurality of apertures in said flanges each aligned to receive a respective pin terminal of said array, the aperture aligned with the signal pin terminal of said array and said signal terminal of said connector being significantly larger than the other apertures so that no contact will be made between the signal pin terminal and the adjacent metal shell in a mated condition of said connector.

2. A method for making electrical interconnection between a coaxial cable and an array of pin terminals fixedly mounted in a circuit board or the like, one pin terminal of said array being a signal pin and the remaining pin terminals being ground pins, comprising the steps of:

terminating the signal conductor of said coaxial cable with a terminal mounted in a connector housing, said terminal being aligned with the signal pin terminal of said array;

enclosing the connector in a pair of mating metal shell members, each respective shell member having at least one arm extending forwardly of the connector with flanges on the free ends of the arms extending transversely thereto to define a plane in front of the mating front end of the connector, apertures in said flanges each aligned to receive a respective pin terminal of said array and the aperture aligned with the signal pin terminal and signal terminal being significantly larger than the other apertures so that no contact will be made between the signal pin terminal and the adjacent metal shell in a mated condition of said connector assembly, and

crimping the shielding of said coaxial cable to said shells whereby ground is established between said shielding and said ground pin terminals upon mating of said connector with said array.

3. An electrical connector for making an interconnection between a coaxial cable and an array of pin terminals fixedly mounted in a circuit board or the like, one pin terminal of said array being a signal pin and the remaining pin terminals being ground pins, said connector comprising:

a housing of rigid insulative material with a plurality of terminal passages extending from a front mating face to a rear surface, said passages being fully enclosed toward said mating face and channel shaped opening outwardly toward the rear surface;

at least one terminal mounted in a respective passage and adopted to engage a signal conductor of said coaxial cable and to detachably mate with the signal pin of said array,

a cover closing the open portion of said passages;

a pair of mating metal shells enclosing the housing, each said shell having an integral arm extending forwardly of the connector, a flange on the free end of each arm extending transversely thereto to define a plane spaced from the mating front end of the housing, a plurality of apertures in each said flanges each aligned with a respective pin of said array and said terminal of said connector with the aperture aligned with the signal pin and signal terminal being significantly larger than the other apertures so that no contact will be made between the signal pin and the adjacent metal shell in a mated condition of said connector assembly; and

a crimp ring securing shielding of said cable to said shells.
