MICRO-CONNECTOR
AND AUTOMATED TOOL FOR APPLICATION THEREOF
BACKGROUND OF THE INVENTION ;
FIELD OF THE INVENTION
The present invention relates to electrical connecting devices employed in the splicing of multiconductor telephone cables comprised of electrical conductors of different or same gauge using only one ~
type of connector, and to automated tools for applying --;
the connecting device. More specifically, the present invention relates to a type of connector for splicing ;~ multiconductor telephone cables which requires a specific application tool, to crimp the connector.
DESCRIPTION OF PRIOR ART
~ In splicing telephone cables, the cable ends are ¦~ arranged to each other and the individual wires in the ¦~ - 20 cables are spliced by the operator or lineman. When the ends of two pairs of wires are bPing connected to each other, it is necessary to make two separate electrical connections, i.e., to connect each corresponding end of the wires of the two pairs.
In accordance with prior art practice, when the ends of a severed telephone cable are being spliced, the lineman first separates from the numerous pairs in each end the particular pairs which are to be conneated. He then separates the two wires in each of the pairs and makes electrical connections between the ends of these wires. After making the connections for these pairs, he ;
..
~ .
''~;'' " ' ''.,' :' ' ~2~Q/l~
can then proceed to a next two pair of wires in the cable and make the electrical connections for it.
In order to facilitate the electrical connections between wires of two pairs, as described above, several connecting systems were developed in which the technician can separate and identify the ends of two pairs of wires. He can then splice the ends of the wires using a speclfic device and an application tool.
Such connectors for splicing telephone cables are already known. However, the connectors commercially available have certain drawbacks, such as size, the amount of wires used by the same connector and the siz~ -of the final splice of the multiconductor telephone cables.
Accordingly, it is desirable to develop a new connector for splicing multiconductor telephone cables which has reduced size in relation to the known connectors, and which can cover a wide range of wire gauges for the same connector. In addition, it covers all combinations of application of cables for connectors o~ prior art and further which reduces the size of the final disadvantages presented by the connectors of prior art.
; Automatic tools for application of connectors of the prior art are usually of the type having a slot which extends transversely between its ends. The wires which should be spliced are generally positioned in the " ~ "
::! ~ ,,'J, ~ , , ' ,, ' ;, .' . ' ; . ~ ~ ' ' , ~

`2-~
slot of the tool and then centrally cut. Further, the automatic application tool positions the wires in the connector to be used and then crimps inwardly the legs of said connector, thus accomplishing the crimping of the connector.
Since the application tools of the prior art cut the wires centrally, they do not permit the use of connectors of reduced sizes. Consequently, such application tools can not be designed to be of the compact type, being heavy and of high manufacture cost.
Further, according to the connectox application tools of prior art, when it is desirable to make a straight splice of telephone wires and a tapping splice, ,, it is necessary to use two application tools, since the application tools of the prior art make only straight splices or tapping splices, i.e., an application tool of prior art does not make the two types of splice using `~
the same tool.
Thus, it is desirable to develop a tool for application of connectors of the automatic type, appropriate to be used with connectors of reduced size, such as the micro-connector of the present invention, such a tool being compact, light and of low manufacture cost, thus overcoming the disadvantages presented by the ~: : . . .
automatic tools for application of connectors of the prior art.

to join 19-26 AWG copper telephone cables with PVC or .
paper insulation of the aerial or underground type, which uses only one type of connector comprised preferably of a copper alloy adhered to a polyester film, the metallic body of said connector being tin coated.
The micro-connector of the present invention has a reduced size, that is approximately half of the length of the connectors of the prior art and, in addition to :~
this, it permits the use of a great amount of wire gauges for the connector, in the range of four wires with different gauges, while the connectors of prior art use at the most three wires of different gauges.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT
The micro-connector 1 which permits the splicing of ~; telephone cables 2A, 2B and 2C of the present invention is preferably made of a copper a:Lloy adhered to a strip
3 of polyester film, the body of said micro-connector being tin coated.
~: 20 The micro-connector 1 of the present invention, best shown in Figure 1, is manufactured in an integral piece having a parallelepipedical body in the shape of a "U" 4, the bottom portion 5 of the said body in "U"
being centrally hollow throughout and slightly narrower than the top portion of the micro-connector 1.
: At the inner ends of the centrally hollow out bottom portion of said micro-connector 1 there are three ~26~
small metallic tongues 6, 7 and 8 in the shape of lances perpendicularly located in relation to the bottom portion of the body in "U" 4, three of them 6A, 7A and 8A being located at a first end of the hollow out portion 5 and the other three 6B, 7s and 8B being located at the other side of the hollow out end 5. Said metallic small tongues 6, 7 and 8 are spaced from each other by small contact slots 9, 10 which are designed to -~
receive the telephone cables 2A, 2B, 2C. The smaller ~ ~-10 contact slots 9A and lOB are designed to receive smaller ;~
gauges of wire and the bigger ones 9B and lOA are ~- -designed to receive bigger gauges of wire. The most external metallic small tongues 6A, 6B, 8~ and 8B have the same siæe and the csntral metallic small tongues 7A
and 7B are similar in size but larger than the external metallic small tongues.
The micro-connector 1 of the present invention has a small positioner rod llA, llB in each inner side wall.
.
The rods are located between legs 16 and 17 and their function is to position wires 2A, 2B, 2C inside of the contact slots 9, 10, which are to be connected.
The micro-connector 1 of the present invention ~ , further has cutouts in the shape of a~V~ 12, 13, 14, 15, ; located at the ends of legs 16, 17 of the "U" of the : .
body 4 of said micro-connector 1.
In order to perform the splicing of telephone -cables using the micro-connector 1 of the present - 9 - 2~.2~
invention, it is necessary to use a specific hand actuated or automated tool, which will be described below, to apply wires 2A, 2B, 2C to be spliced which are positioned in said tool, which in its turn places wires 2A, 2B, 2C in the corresponding contact slots 9A, 9B and lOA, lOB. Then, the above mentioned application tool crimps inwardly the legs 16, 17 of the body in the shape of a "U" of connector 1 in order that the wires 2A, 2B, 2C to be spliced are urged into the contact slots 9A, 9B
and lOA, lOB with the help o~ the positioner rods llA, llB. In this operation, when wires 2A, 2B, 2C are urged to enter in the contact slots 9A, 9B, lOA, lOB, the metallic small tongues 6, 7, 8 break through the insulator of the wire until touching the wire itself and accomplish the eleictrical connaction.
Accordingly, the same connector 1 can be used to make splices of wires of different gauges as illustrated in Figures 6, 7 and 8.
It will be noted that the present invention discloses a micro-connector, which splices telephone cables, that is of simple design but is effective and of low cost. The application of the connector is performed , by means of an automatic tool 31 which will now be ~ described in detail.
¦~ An automatic tool 21 for application of connectors ¦~ of the prior art is illustrated in Figures 9 and 10, and presents a central cut system 29, i.e., the wires are 1567? CA
- lo 2~
positioned in front of each other after cutting.
Additionally, said tools present an angular movement of crimping of connectors and a pressing power system of connectors which uses a cam, that is, an operating handle 23 of 360 degrees of rotation. On the other hand, the application tool 31 of the present invention is provided with a cut system which cuts by the ends 39, i.e., the wires are positioned side by side after the ~ ;
cutting. Furthermore, said tool 31 presents a 10 horizontal movement of crimping of connectors 1, which ;~
are in the form of a micro-connector strip 32, and a pressing power system of micro-connectors which uses an operating lever 33.
The automatic tool 31 for application of micro-connectors strip 32, of the present invention, best ~-shown in Figure 11, has an operating handle 33, one fixed die which is an anvil 34 and one movable die which -is a crimper 35, wire supports 36 for the wires to be ;~ spliced, a feed knob 37 for feeding the reeled micro-~ 20 connectors and a transport catch 38 to transport the ¦~ ~ strip of micro-connectors.
- ~ The operating handle, as its name indicates, ~
~ operates the application tool 31. One complete forward -.
and reverse motion is equal to one complete crimp cycle ~
. ...
of a micro-connector. The operating handle 33, further has a spring which automatically returns the operating ,.

lever 33 to the starting position to crimp the next micro-connector of the strip of micro-connectors 32.
The anvil 34 and the crimper 35 crimp the micro-connectors, i.e., the application tool 31 applies the micro-connectors to the wires by crimping them between the anvil 34 and crimper 35.
The wire supports 36, located in the side ends of the application tool 31, position and hold the wires in the crimpers 34 and 35. Two cutting blades 45 to cut the wires are secured in the sides of the application tool, which cut the wire ends against the sides of the crimper 35 when it adva~ces. Two blades 39 for cutting the micro-connectors 32 of the strip are secured by ~eans of a screw 40 and a cover 41 in the anvil 34.
; ~ A feed knob 37, which can rotate clockwise or anti-clockwise, rotates a feed sprocket forward or backward , in order that the micro-connectors strip 32 forward to start the application of micro-cc~nnectors or backwards to remove the skrip of micro-connectors 32 of the application tool 31.
The application tool 31 of the present invention further has a transport catch 38 which automatically advances feed sprocket when the operating handle 33 is pushed backward.
In order to join the wires using a micro-connector strip 32 and the application tool 31 of the present invention i5 necessary, in first place, to insert micro-~.
. .
connector strip 32 in the application tool 31, as follows: . .
a) cut carrier strip 32 midway between two micro- ..
connectors;
b) open protective cover 42 of application tool 31 and, with the open side of the micro-connectors ~3 facing the application tool 31, start the connector .~. .
strip into the guide channel of the application tool 31;
c) guide the micro-connector strip 32 over a guide channel, making the return through roller 44 and into the sprocket; ~
d) hold micro-connector strip 32 in the right :~ :
position and rotate feed knob 37 slowly until certain ;
that micro-connector strip 32 is started in the application tool 31; and e) rotate feed Xnob 37 until the third micro-: connector is aligned on the anvil 34 of the application tool 31 and the carrier strip exist in the exit end of .~ the application tool 31.
: 20 In joining telephone cahles, using the application tool 31 of the present invention vith the micro-connector strip 32 already inserted in the application tool 31, it is nscessary to centralize the application ~:~ tool 31 in relation to the telephone cables in a way ~
that the splices are not loose or decentralized. A~ter ;;
that, take a wire from the right side of the application tool 31 and lace it through the wire support 7 and out ,' ::: 15672 CA ~

between the crimpers 34, 35. Then, take a second wire from -the other side of the application tool 31 and lace it through the other wire support 36 and out between the crimpers 34, 35. Finally, cycle the application tool 31 by pushing the operating handle 33 forward until bottomed and then allow it to return freely. Next, repeat the above steps for the other pair of wires.
Accordingly, the automatic tool for application of micro-connectors 1 can be used for splicing telephone cables using micro-connectors strip.
Although the invention has been shown and described with respect to a best mode embodiment thereof, it should be understood by those skilled in the art that the foregoing and various other changes, omissions and `~ additions in the form and detail thereof may be made ~:

gauges of wire and the bigger ones 9B and lOA are ~- -designed to receive bigger gauges of wire. The most external metallic small tongues 6A, 6B, 8~ and 8B have the same siæe and the csntral metallic small tongues 7A
and 7B are similar in size but larger than the external metallic small tongues.
The micro-connector 1 of the present invention has a small positioner rod llA, llB in each inner side wall.
.
The rods are located between legs 16 and 17 and their function is to position wires 2A, 2B, 2C inside of the contact slots 9, 10, which are to be connected.
The micro-connector 1 of the present invention ~ , further has cutouts in the shape of a~V~ 12, 13, 14, 15, ; located at the ends of legs 16, 17 of the "U" of the : .
body 4 of said micro-connector 1.
In order to perform the splicing of telephone -cables using the micro-connector 1 of the present - 9 - 2~.2~
invention, it is necessary to use a specific hand actuated or automated tool, which will be described below, to apply wires 2A, 2B, 2C to be spliced which are positioned in said tool, which in its turn places wires 2A, 2B, 2C in the corresponding contact slots 9A, 9B and lOA, lOB. Then, the above mentioned application tool crimps inwardly the legs 16, 17 of the body in the shape of a "U" of connector 1 in order that the wires 2A, 2B, 2C to be spliced are urged into the contact slots 9A, 9B
and lOA, lOB with the help o~ the positioner rods llA, llB. In this operation, when wires 2A, 2B, 2C are urged to enter in the contact slots 9A, 9B, lOA, lOB, the metallic small tongues 6, 7, 8 break through the insulator of the wire until touching the wire itself and accomplish the eleictrical connaction.
Accordingly, the same connector 1 can be used to make splices of wires of different gauges as illustrated in Figures 6, 7 and 8.
It will be noted that the present invention discloses a micro-connector, which splices telephone cables, that is of simple design but is effective and of low cost. The application of the connector is performed , by means of an automatic tool 31 which will now be ~ described in detail.
¦~ An automatic tool 21 for application of connectors ¦~ of the prior art is illustrated in Figures 9 and 10, and presents a central cut system 29, i.e., the wires are 1567? CA
- lo 2~
positioned in front of each other after cutting.
Additionally, said tools present an angular movement of crimping of connectors and a pressing power system of connectors which uses a cam, that is, an operating handle 23 of 360 degrees of rotation. On the other hand, the application tool 31 of the present invention is provided with a cut system which cuts by the ends 39, i.e., the wires are positioned side by side after the ~ ;
cutting. Furthermore, said tool 31 presents a 10 horizontal movement of crimping of connectors 1, which ;~
are in the form of a micro-connector strip 32, and a pressing power system of micro-connectors which uses an operating lever 33.
The automatic tool 31 for application of micro-connectors strip 32, of the present invention, best ~-shown in Figure 11, has an operating handle 33, one fixed die which is an anvil 34 and one movable die which -is a crimper 35, wire supports 36 for the wires to be ;~ spliced, a feed knob 37 for feeding the reeled micro-~ 20 connectors and a transport catch 38 to transport the ¦~ ~ strip of micro-connectors.
- ~ The operating handle, as its name indicates, ~
~ operates the application tool 31. One complete forward -.
and reverse motion is equal to one complete crimp cycle ~
. ...
of a micro-connector. The operating handle 33, further has a spring which automatically returns the operating ,.

lever 33 to the starting position to crimp the next micro-connector of the strip of micro-connectors 32.
The anvil 34 and the crimper 35 crimp the micro-connectors, i.e., the application tool 31 applies the micro-connectors to the wires by crimping them between the anvil 34 and crimper 35.
The wire supports 36, located in the side ends of the application tool 31, position and hold the wires in the crimpers 34 and 35. Two cutting blades 45 to cut the wires are secured in the sides of the application tool, which cut the wire ends against the sides of the crimper 35 when it adva~ces. Two blades 39 for cutting the micro-connectors 32 of the strip are secured by ~eans of a screw 40 and a cover 41 in the anvil 34.
; ~ A feed knob 37, which can rotate clockwise or anti-clockwise, rotates a feed sprocket forward or backward , in order that the micro-connectors strip 32 forward to start the application of micro-cc~nnectors or backwards to remove the skrip of micro-connectors 32 of the application tool 31.
The application tool 31 of the present invention further has a transport catch 38 which automatically advances feed sprocket when the operating handle 33 is pushed backward.
In order to join the wires using a micro-connector strip 32 and the application tool 31 of the present invention i5 necessary, in first place, to insert micro-~.
. .
connector strip 32 in the application tool 31, as follows: . .
a) cut carrier strip 32 midway between two micro- ..
connectors;
b) open protective cover 42 of application tool 31 and, with the open side of the micro-connectors ~3 facing the application tool 31, start the connector .~. .
strip into the guide channel of the application tool 31;
c) guide the micro-connector strip 32 over a guide channel, making the return through roller 44 and into the sprocket; ~
d) hold micro-connector strip 32 in the right :~ :
position and rotate feed knob 37 slowly until certain ;
that micro-connector strip 32 is started in the application tool 31; and e) rotate feed Xnob 37 until the third micro-: connector is aligned on the anvil 34 of the application tool 31 and the carrier strip exist in the exit end of .~ the application tool 31.
: 20 In joining telephone cahles, using the application tool 31 of the present invention vith the micro-connector strip 32 already inserted in the application tool 31, it is nscessary to centralize the application ~:~ tool 31 in relation to the telephone cables in a way ~
that the splices are not loose or decentralized. A~ter ;;
that, take a wire from the right side of the application tool 31 and lace it through the wire support 7 and out ,' ::: 15672 CA ~

between the crimpers 34, 35. Then, take a second wire from -the other side of the application tool 31 and lace it through the other wire support 36 and out between the crimpers 34, 35. Finally, cycle the application tool 31 by pushing the operating handle 33 forward until bottomed and then allow it to return freely. Next, repeat the above steps for the other pair of wires.
Accordingly, the automatic tool for application of micro-connectors 1 can be used for splicing telephone cables using micro-connectors strip.
