## Abstract

A hand-held tool for terminating connectors onto a coaxial cable has an elongated body and an end stop and plunger on the body, the plunger being controlled by a lever arm which will axially advance the plunger toward and away from the end stop to radially compress a portion of the connector into firm crimping engagement with the end of the coaxial cable. To accommodate different lengths of connectors, a plunger permits mounting of different length adapter tips to vary the axial spacing between the adapter tips and the end stop according to the length of connector being terminated.

## Claims

### Claim 1

An adapter tip for a compression tool of the type having a force-applying means to axially advance a plunger in order to radially compress a connector into engagement with a coaxial cable end, said adapter tip comprising:
a rearward portion movable into seating engagement with an end of said plunger and provided with an enlarged end configured to engage the tool, and
a forward portion having a reduced outer diameter relative to the rearward portion and provided with a central bore and an upward facing slot, the forward portion configured to engage the connector and enable radial compression of the connector into engagement with the coaxial cable end.

### Claim 2 (depends on 1)

The adapter tip according to claim 1 wherein said rearward portion includes a central bore communicating with said slot.

### Claim 3 (depends on 1)

The adapter tip according to claim 1 wherein said central bore is threaded.

### Claim 4 (depends on 1)

The adapter tip according to claim 1 wherein said forward portion is in the form of a cylindrical extension of said rearward portion.

### Claim 5 (depends on 1)

The adapter tip of claim 1, wherein the enlarged end of the rearward portion comprises a radially enlarged portion extending about the outer circumference of the rearward end.

### Claim 6

An adapter tip for a compression tool of the type having a force-applying means to axially advance a plunger in order to radially compress a connector into engagement with a coaxial cable end, said adapter tip comprising:
a rearward portion movable into seating engagement with an end of said plunger and provided with an enlarged end configured to engage the tool, and
a forward portion having a reduced outer diameter relative to the rearward portion and provided with a central bore and an upward facing slot, the forward portion configured to engage the connector and enable radial compression of the connector into engagement with the coaxial cable end;
wherein the slot is channel-shaped and extends axially through said forward portion and partially into said rearward portion.
