## Background
FIELD OF THE INVENTION
The invention is in the field of compression tools used for compressing connector ends onto wire or cable for the production of connector cables.
BACKGROUND
The electronics, telecommunications, and cable television industries have used a variety of cables and wires to perform various jobs. Each cable or wire has various size and shaped connectors based upon either an industry standard or in some cases a proprietary manufacturing standard. The industry has used compression tools to attach various size and types of connectors onto wires. Some of the known compression tools may utilize a universal compression head in combination with an appropriate adapter to attach a connector of a specific length, diameter or other dimension.
This type of compression tool with an adjustable adapter to vary connector size is compact because it is designed to fit only one connector at a time. This is great for ease of handling and storage. Initially, in the early stages of a universal compression tool's life span the tool works as intended, but there are many drawbacks as the tool ages. One drawback is that the adapters can be lost or damaged. Another drawback is that depending on the design the additional moving parts create wear, looseness of the insert and eventual failure of the compression tool. The instant invention addresses the abovementioned drawbacks of the universal connector compression tool.

DETAILED DESCRIPTION OF THE INVENTION
The invention solves the aforementioned problems of premature wear or losing driver pins by having multiple adaptor accessories mounted within the tool for interchange by the user. A multiple drive pin size compression tool 100 is made to allow for the compression of different dimensioned connecters onto different diameter wires. The tool 100 comprises a body 10 having an interior 15. The body 10 can be made of any relatively rigid material such as plastics that could be injection molded or metal that could be stamped or shaped.
A handle 20 is movably attached to the body 10. The handle 20 can be attached by rivets, screws or a hinge, but the handle 20 must be allowed to be rotatably moveable with respect to the body 10. To perform the operation of compression an operator may start by placing the connector 200 into the body 10 of the tool. There is at least one compression chamber portion 30 within the interior of the body 10 that is configured for receiving a connector 200. FIG. 1 shows a connector 200 within the compression chamber portion 30 that is substantially fully compressed onto a wire 300. FIG. 2 shows the same compression chamber 30 in the substantially fully compressed position without a connector 200 being present. When the handle 20 is raised away from the body 10 the length of the compression chamber 30 may expand sufficiently in length to fit in an uncompressed connector 200.
Adjacent the compression chamber 30 within the interior of the end of the body 10 may be a cable cradle 70 having at least two cable receiving portions 75 of different dimensions, wherein the cable cradle 70 may be movably affixed to the body 10. At the other side of the compression chamber 30 is a driver pin assembly 40 operatively coupled to the handle 20, wherein said assembly 40 has a first driver pin position 42 and a second driver pin position 43 wherein at least two different dimensioned driver pins 44, 45 may be removably affixed to the driver pin assembly. The operator may switch the assembly 40 between the two positions to select one of the correctly dimensioned pins 44, 45 from the assembly 40 to compress the connector 200.
The driver pin assembly 40 may be directly coupled to the handle 20 or to a sliding head 50 having a receiving portion 52 that is configured to interact with the driver pin assembly 40 and the handle 20. The use of the sliding head 50 together with the driver pin assembly 40 may help to stabilize the diver pin assembly 40 over being used directly coupled to the handle 20 through better angles of force being directed through the translation path of the handle. A receiving portion 52 within the sliding head 50 accepts the protruding component 47, 48 of the driver pin assembly 40. Means for compressing differently sized connectors may include the driver pin assembly 40 having at least two different dimensioned driver pins 44, 45 operable between two driver pin positions 42, 43 and configured to drive connectors having dimensions corresponding to driver pins 44, 45 and driver pin positions 42, 43. Optionally a toggle lever 60 may be affixed between the handle 20 and the sliding head 50. The toggle lever 60 may allow a greater force to be directed linearly between the driver pin 44, 45 into a connector 200 into the cable cradle 70.
The cable cradle 70 may be movable so a retaining member 74, 76 may be affixed to the body 10 to accurately position the cable cradle 70 within the body 10. This retaining member 74, 76 may help to align the cable cradle 70 so that the connector 200 can be installed without any misalignment, but the compression of a connector 200 will still work without the cable cradle retaining member 74, 76.
With the handle down the distance between the end of the first driver pin 44 and the cable cradle 70 is a first compressed length 80 that corresponds to the driver pin assembly 40 being in the first driver pin position 42 as shown in FIGS. 1-4. The distance between the second driver pin 45 and the cable cradle 70 is a second compressed length 85 that corresponds to the driver pin assembly 40 being in the second driver pin position 47 as shown in FIGS. 5-7.
To move from one position to the other the driver pin assembly 40 should be unlocked from the tab receivers 52. In FIG. 9 the driver pin assembly 40 is unlocked by moving in direction 80 opposite the force of compression of the connector, which is helpful to ensure tightness of the assembly during the compression of the connector 200.
The driver pin assembly 40 has a first driver pin locking tab 47 associated with the first driver pin position 42 and a tab receiver 52 on the sliding head 50 that is engaged by sliding the tab 47 into the tab receiver 52 or instead the tab and tab receiver could be any shape with a corresponding male or female counterpart to align and secure the driver pin assembly 40. The second driver pin position 46 coincides with a second driver pin locking tab 48 being associated with the tab receiver 52. To move the driver pin assembly 40 between locked positions the tab 47 is disengaged from the sliding head 50. Other mechanical means of positioning and repositioning the driver pins of the driver pin assembly 40 can be envisioned to be equivalent. For example, a mechanical retaining system that could also suffice like a detent with a ball and spring, pin and corresponding hole, or both surfaces being flat and parallel, would be sufficient to hold the driver pin assembly 40 in proper alignment when moved between the selected positions.
Once disengaged the sliding head 50 has a protruding component 54 that is configured to interact with the driver pin assembly 40 that have an “L” shaped or other shaped hollow receiving portion 49 within the driver pin assembly 40 that would accept the protruding component 54 of the sliding head 50. If the driver pin assembly is configured to hold three driver pins it may have a “sideways T” shaped hollow section for a receiving portion 49.
To change the driver pin position of the driver pin assembly 40 locking tab 47 or 48 is disengaged from the tab receiver 52 of the sliding head 50. Once the locking tab 47, 48 is disengaged from the sliding head 50 the driver pin assembly 40 can be rotated within the “L” shaped hollow receiving portion 49 around protruding component 54 until the other locking tab 47, 48 is positioned to be inserted into the tab receiver 52 of the sliding head 50 with the desired driver pin positioned. The selected locking tab 47, 48 is then pushed into the tab receiver 52 until it is fully seated. Once seated the driver pin assembly is positioned to form a compression chamber 30 dimensioned to fit a different connector 200.
The tool is adjustable as shown in FIGS. 3 and 4 in that it is able to form compression chambers of different compressed lengths. When the driver pin assembly is in the first driver pin position 42 it forms a first compression channel portion 31 adjacent of the sliding head 50 for receiving a connector 200 of a first dimension. When a connector 200 of a different length is present for compression then a second compression channel portion 32 adjacent of the sliding head 50 for receiving a connector 200 of a second dimension can be formed when the driver pin assembly 40 is in the second driver pin position 43. Further adjustability is possible by the complete removal of the driver pin assembly 40 and replacement with an assembly having different dimensioned driver pins or a third driver pin could be added for even greater adjustability.
When a different driver pin 44, 45 is desired it is usually because it correlates to a different sized connector 200 made for a different dimensioned wire 300. The cable cradle 70 can be adjusted to be in either a first diameter cable cradle position 78 or a second diameter cable cradle position 79 by unlocking and rotating the cable cradle 70 as shown in FIG. 4. The cable cradle 40 is in a locked position 80 in FIG. 2 when it rests against alignment stops 74, 76. To adjust the cable cradle 70 it is first slid into the unlocked position 81 away from the alignment stops 74, 76 into cable cradle opening 83. When in opening 83 the cable cradle 70 is swivelled 180 degrees until the other sized cable cradle opening is aligned. Once aligned the cable cradle 70 is slid from unlocked position 81 to locked position 80.
In another embodiment is a multiple driver tip compression tool for multiple diameter wires 100 that comprises a body 10 having an interior, a top 11, a bottom 12, a first side 13 and a second side 14 each side having a guidance portion 16 therein. To provide force to compress the connector 200, a handle 20 is provided, wherein the handle 20 is pivotally attached to the body 10 between the first side 13 and the second side 14. The handle 20 when compressed or raised directly acts upon a toggle lever 60 affixed to the handle 20. The toggle lever 60 acts upon a sliding head 50 having a guidance component 17, wherein the guidance component 17 of the sliding head 50 is both retained and movable within the retainer portion 16 of the body 10.
To compress the connector a driver pin assembly 40 having at least two differently dimensioned driver pins 44, 45 are operatively coupled to the sliding head 50 wherein said assembly 40 has a first driver pin position 42 and a second driver pin position 43. The driver assembly 40 is adjacent a compression channel portion 30 configured to receive a first connector 200 when the driver pin assembly 40 is in the first driver pin position 42, and a second connector 201 when the driver pin assembly 40 is in the second driver pin position 47. Optionally an adjustable cable cradle 70 having at least two different dimensioned receiving portions 75, 79, wherein the cradle 70 is rotatably 72 affixed to the body 10 between the first side 13 and the second side 14. The driver pin assembly 40 rests upon a protruding component 54 of the sliding head 50 within a receiving portion 49 of the driver pin assembly 40. The protruding component 54 on the sliding head 50 may be a post that removably retains the driver tip unit 40 rotatably to the sliding head 50. Optionally the tool may instead include a driver tip unit 40 that is removably affixed within the body 10 for exchange with a second driver tip unit 40a. 
Each of the driver pins 44, 45 have a first compressed length 35 that corresponds to the compression channel portion 30 adjacent of the head 30 when the driver pin assembly 40 is in the first driver tip position 36 and a second compressed length 32 that corresponds to the compression channel portion 30 adjacent of the head when the driver pin assembly 40 is in the second driver tip position 37.
A method of affixing a cable connector 200 to a wire 300 comprises the steps of: providing a body 10 having an interior 15, a handle 20, wherein the handle 20 is movably attached to the body 10, at least one compression chamber portion 30 within the interior 15 of the body 10 that is configured for receiving a connector 200, a cable cradle 70 having at least two differently dimensioned cable receiving portions 75, 79, wherein the cable cradle 70 is rotatably affixed to the body 10, a driver pin assembly 40 having at least two driver pins 44, 45 operatively coupled to the handle 20 wherein said assembly 40 has a first driver pin position 41 and a second driver pin position 42, and at least two different dimensioned driver pins 44, 45 affixed to the driver pin assembly 40.
The next step is providing an appropriate driver pin 44, 45 for the cable connector 200 for the wire 300 and then providing a wire 300. Then inserting the cable connector 200 and the wire 300 and selecting an appropriately sized driver tip 44, 45 in the body 10 that corresponds to the driver tip position 41, 42. Then rotating or moving the driver pin assembly 40 to the appropriate driver tip position 41, 42. The next step is moving or rotating the cable cradle 70 to the appropriate wire dimension position 78.
Once the tool has been set up to the right driver pin 44, 45 and cable cradle 70 then the next step is moving the sliding head 50 to drive the cable connector 200 onto the wire 300 forming a connector cable 301; and, then removing the connector cable 301 from the body 10.
If the tool does not contain the proper sized driver tips 44, 45 then the proper step is providing a second driver tip assembly 40a; removing the driver tip assembly 40; and, inserting the second driver tip assembly 40a having an appropriately sized driver tip 44a, 45a onto the sliding head 50 in the body 10. If the tool 100 has a handle 20 to move the sliding head 50 then the proper step is compressing the handle 20 to move the sliding head 50.
