Abstract

This invention in its preferred embodiment, is directed to a miniature UHF type plug, more particularly to a female, snap-on coaxial cable connector for use with radio-frequency and other transmission lines, where such connector is electrically connectable to a male, receptacle connector, typically panel mounted and of a design as known in the art. The snap-on, coaxial connector comprises three primary members identified as a circular sleeve, a circular shell, and a circular collar. The circular sleeve includes a plurality of spaced-apart, axially oriented tynes along a first end thereof, and the circular shell consists of a cable crimping section, an intermediate section to be received within the sleeve, and a third section having a like plurality of spaced-apart, axially oriented tynes. The latter tynes are arranged to intermate with the first tynes, and the intermated tynes are adapted to receive the male, receptacle connector. The shell is further characterized by means to retain the axial position of the shell within said sleeve, and by means cooperating with the male, receptacle connector to prevent rotative movement therebetween, where preferably such means comprise a compliant, elastomeric spacer member. The circular retaining collar is provided to receive the sleeve, and cooperative means are further provided between the collar and the sleeve to limit the axial movement therebetween.

Claims

1. A female, snap-on coaxial cable connector for use with radio-frequency and other transmission lines and electrically connectable with a male, receptacle connector, said female, snap-on, coaxial connector comprising

a) a circular sleeve having a plurality of spaced-apart, axially oriented tynes along a first end thereof,

b) a circular shell consisting of a cable crimping section, an intermediate section to be received within said sleeve, and a third section having a like plurality of spaced-apart, axially oriented tynes, where the latter tynes are arranged to intermate with said first tynes, and said intermated tynes are adapted to receive said male, receptacle connector,

i) said shell including means to retain the axial position of said shell within said sleeve,

ii) said shell further including means cooperating with said male, receptacle connector to prevent rotative movement therebetween, and

c) a circular retaining collar within which said sleeve is received, where cooperative means are provided between said collar and said sleeve to limit the axial movement therebetween.

2. The female, snap-on, coaxial cable connector according to claim 1, where said male, receptacle connector is externally threaded, and that said first tynes include helically oriented ribs for engagement with said threads.

3. The female, snap-on, coaxial cable connector according to claim 1, wherein the opposite end of said sleeve includes a plurality of axially oriented beams, where a number of said beams include an inwardly directed, annularly arranged rib for engagement with a corresponding groove in said intermediate section of said circular shell.

4. The female, snap-on, coaxial cable connector according to claim 3, wherein at least a pair of said beams include outwardly directed, radial ramps for engagement with a circumferential slot within said circular retaining collar.

5. The female, snap-on, coaxial cable connector according to claim 4, wherein there are at least a second pair of said beams having outwardly, directed ramps and axially offset from said remaining beams.

6. The female, snap-on, coaxial cable connector according to claim 2, where said male, receptacle connector includes a continuous row of axially oriented teeth along a mating face thereof, and said shell is provided with an elastomeric spacer member to coact with said teeth to prevent relative rotative movement between said male, receptacle connector, and said female connector.

7. The female, snap-on, coaxial cable connector according to claim 5, wherein during assembly of said connector said radial ramps engage said circumferential slot to define a preliminary assembled position, and after further relative axial movement of said sleeve to said collar said outwardly directed ramps engage said circumferential slot.

8. The female, snap-on, coaxial cable connector according to claim 7, wherein said tynes include tapered surfaces which are cammed against the wall of said collar to radially restrict the opening between said tynes.
