## Abstract

An RF connector switch (18) includes an outer metallic shell (19) containing a dielectric core (49) and contacts (64, 66) having ends (62, 68) in coaxial ports (21, 35). The contacts (64, 66) include second ends (62, 72) aligned with a port (44) in the shell (19) through which a pin (69) may be inserted to operate the ends (62, 74) as a switch.

## Claims

### Claim 1

A connector/switch of a type utilized to interconnect and disconnect RF signal ports through a switching action comprising a shell formed of box-like metallic parts having interesting edges to provide a shielding structure, a dielectric core having an exterior configuration to fit within said shell to provide dielectric parameters of an RF transmission path through said shell, the said core having interior dimensions to grip and hold a pair of contacts within said shell insulated therefrom, the pair of contacts each having one end forming a coaxial port in conjunction with said shell and said dielectric core and a second and in engagement forming a normally closed switch internally of said shell, said shell including an aperture axially aligned with said contacts second ends and said core being relieved internally to facilitate displacement of said second ends to allow said ends to be displaced relatively to effect a switch action, the said aperture positioned to receive the insertion of a pin element engaging said contacts to effect said displacement and upon withdrawal facilitate the restoration of an interconnection between said contacts to connect said ports electrically for RF energy transfer characterized in that one of said ports includes an interior threading adapted to receive the exterior threading of a coaxial connector connected to an antennae to support such antennae in a freestanding relationship relative to said connector switch.

### Claim 2 (depends on 11)

The connector switch of claim 11 wherein both said contacts are formed of round wire of spring grade material having the ends flattened to assure an effective interconnection area therebetween.

### Claim 3

A connector/switch of a type utilized to interconnect and disconnect F signal ports through a switching action comprising a shell formed of box-like metallic pas having interesting edges to provide a shielding structure, a dielectric ore having an exterior configuration to fit within said shell to provide dielectric parameters of an RF transmission path through said shell, the said core having interior dimensions to grip and hold a pair of contacts within said shell insulated therefrom, the pair of contacts each having one end forming a coaxial port in conjunction with said shell and said dielectric core and a second end in engagement forming a normally closed switch internally of said shell, said shell including an aperture axially aligned with said contacts second ends and said core being relieved internally to facilitate displacement of said second ends to allow said ends to be displaced relatively to effect a switch action, the said aperture positioned to receive the insertion of a pin element engaging said contacts to effect said displacement and upon withdrawal facilitate the restoration of an interconnection between said contacts to connect said ports electrically for RF energy transfer characterized in that one of said ports has an exterior threading to facilitate the mounting of said connector switch to a panel having an aperture therein with said heading receiving a nut to lock said connector switch to said panel.

### Claim 4

A connector/switch of a type utilized to interconnect and disconnect RF signal pots through a switching action comprising a shell formed of box-like metallic parts having interesting edges to provide a shielding structure, a dielectric core having an exterior configuration to fit within said shell to provide dielectric parameters of an RF transmission path through said shell, the said core having interior dimensions to grip and hold a pair of contacts within said shell insulated therefrom, the pair of contacts each having one end forming a coaxial port in conjunction with said shell and said dielectric core and a second end in engagement forming a normally closed switch internally of said shell, said shell including an aperture axially aligned with said contacts second ends and said core being relieved internally to facilitate displacement of said second ends to allow said ends to be displaced relatively to effect a switch action, the said aperture positioned to receive the insertion of a pin element engaging said contacts to effect said displacement and upon withdrawal facilitate the restoration of an interconnection between said contacts to connect said ports electrically for RF energy transfer characterized in that one of said parts includes an interior threading adapted to receive the exterior threading of a coaxial connector connected to an antennae to support such antennae in a freestanding relationship relative to said connector switch and the said shell includes portions of a wall thickness to provide support of an antennae structure mounted on one of said RF ports.

### Claim 5

A connector/switch of a type utilized to interconnect and disconnect RF signal ports through a switching action comprising a shell formed of box-like metallic parts having interesting edges to provide a shielding structure, a dielectric core having an exterior configuration to fit within said shell to provide dielectric parameters of an RF transmission path through said shell the said core having interior dimensions to grip and hold a pair of contacts within said shell insulated therefrom, the pair of contacts each having one end forming a coaxial port in conjunction with said shell and said dielectric core and a second end in engagement forming a normally closed switch internally of said shell, said shell including an aperture axially aligned with said contacts second ends and said core being relieved internally to facilitate displacement of said second ends to allow said ends to be displaced relatively to effect a switch action, the said aperture positioned to receive the insertion of a pin element engaging said contacts to effect said displacement and upon withdrawal facilitate the restoration of an interconnection between said contacts to connect said ports electrically for RF energy transfer characterized in that there is included a ring element fitted over said shell parts to clamp said shell pats together at one end with the said shell interesting edges holding said shell parts together proximate the other end.
