  • a first embodiment of this invention relates to modular terminal blocks suitable for attaching telecommunication drop wires to binding posts in terminals blocks which are in turn connected to telecommunication cables or other equipment.
  • the invention relates to adaptors for use on prior art terminal blocks which require striping of insulation from wires before connection to binding posts where they were secured with a washer and simple nut.
  • terminal blocks have been used in the telecommunications industry which typically require the stripping of the drop wires before attaching the drop wires to the binding posts in the terminal block.
  • An example of such terminal blocks is the Western Electric 9Al which typically contains 5,10 or more pairs of binding posts for attaching drop wires or service wires.
  • the terminal block may also contain circuit protection devices.
  • the binding posts and the stripped portion of the drop wire or service wire are left exposed to moisture, corrosion, insects and other environmental factors which interfere with the reliability of the electrical connection intended between the drop wires or service wires and the terminal block binding posts.
  • Other types of terminal blocks contain insulation-displacement type connections which cause the wires to break or corrode.
  • This invention can provide an improved device such as a modular terminal block or adaptor which allows the worker to make a connection between a wire and binding post without prestripping the insulation from the wire.
  • the invention can also provide an improved terminal block or adaptor that prevents corrosion or other damage of the wire connected to the binding post.

  • the invention further provides a terminal block adaptor for connecting an insulated wire to a conductive threaded binding post of a terminal block, which adaptor comprises an insulative collar and a threaded cap wherein: the collar has (a) a first opening therethrough which is smaller in one portion for receiving the binding post from one side of the collar and is larger in another portion for receiving the cap from the opposing side of the collar thereby forming a shoulder in the first opening proximate to the bottom of the cap when installed whereby thread means in the cap can engage thread means on the binding post and (b) a second opening in a lateral side thereof, communicating with the first opening and being positioned laterally opposite from the position of the binding post received in the first opening, for receiving an insulated wire whereby the wire is positioned by the second opening at least in part adjacent the binding post and underneath the cap and is engaged by the cap when the cap is threaded on the binding post; and the cap comprises a conductive inner portion and an insulative outer portion wherein the conductive inner portion has thread means adapted to
  • the terminal block preferably has edge means of the cap positioned at an appropriate distance from the shoulder means in the cap and has an appropriate configuration whereby when the shoulder in the cap engages the first shoulder means of the terminal posts the edge means of the cap makes contact through the insulation to the conductor in a wire of a minimum predetermined size and whereby the edge portion of the cap can engage a conductor in a larger wire through the insulation thereof by compressing the wires against the second shoulder means of the binding posts without severing the wire and without the shoulder means in the cap engaging the first shoulder means of the binding posts when the larger wire is present.
  • Openings in the housing of the terminal block contain a sealing material (preferably a gel) which is placed under compressive force when the wire is inserted into the opening means in the housing and binding posts and the cap means is advanced against the wire to make connection with a conductor in the wire.
  • a sealing material preferably a gel
  • the cap of the terminal block preferably has conductive means connected with the inner conductive portion which conductive means is accessible through an opening in the outer insulative portion of the cap to provide access for test probe for testing the connection made by the cap.
  • the housing of the terminal block preferably has a base adapted for mounting on a substrate and wherein the binding posts and associated openings in the housing are positioned at an angle of at least 20° from normal to the base to thereby facilitate visibility by the worker when inserting the wires into the opening means.
  • the terminal block adapter preferably has cooperative stop means comprising a shoulder on the cap which engages an outside surface of the collar.
  • the terminal block adapter preferably has cooperative stop means comprising a portion of the shoulder means in the first opening means which engages the edge means of the cap thereby leaving the desired preselected distance between the edge means of the cap and another portion of the shoulder means where the wire is positioned between the cap and the shoulder means.
  • the terminal block adapter preferably has a sealing material (preferably a gel) in at least one of the opening means for environmentally sealing the wire, binding post, or cap.

  • Figure 10 is a cross section of a collar and cap of the second preferred embodiment of the invention on a binding post.
  • Figure 11 shows a further application of an adaptor of the second preferred embodiment of the invention.
  • Figure 1 shows a conventional terminal block 1 which contains pairs of threaded binding posts 2.
  • wires 3 are striped of insulation at the end and the wire wrapped around binding posts 2 and held in place by washers 4 and threaded nut 5.
  • Figure 2 shows one configuration of a five pair terminal block having two banks of binding posts configured for three pairs in the bottom tier and two pairs in the upper tier.
  • Terminal block 11 comprises a housing 12, binding posts 13 and caps 14. Openings 15 in the binding posts are aligned with openings 16 in housing 12 whereby the wire intended to be connected to the binding posts can be inserted through opening 16 and received into opening 15 in the binding posts. It is preferred that the opening 15 extend all the way through the binding posts so that the wire may be inserted completely through binding posts 13 until it abuts against the wall of opening 17 in housing 12.
  • Binding post 13 has threaded portion 18 and shoulder means 19 positioned between threaded portion 18 and opening 15. Binding post 13 has second shoulder means 110 for supporting the wire when compressed by the cap.
  • the bottom portion 111 of binding post 13 can be of any conventional or desired configuration for interconnection with the desired component.
  • portion 111 may be connected to a wire tail which is in turn spliced to a cable.
  • portion 111 may be an opening for interconnecting with other electronic or electric components such as circuit protection devices or disconnect devices.
  • the cap 14 contains an inner conductive portion 112 which is threaded for engagement with the threaded portion 18 of binding post 13.
  • the inner conductive portion of the cap has shoulder means 113 adapted for engaging shoulder means 19 on binding post 13.
  • the inner conductive portion 112 of cap 14 has edge portion 114 adapted for engaging the wire and compressing the wire against second shoulder means 110 of binding post 13.
  • the inner conductive portion 112 of cap 14 is covered by outer insulative portion 115.
  • the outer portion 115 of cap 14 may be solid for full enclosure or may contain preferred access opening 116 for test probe access to either the conductive inner portion 112 of cap 14 or the top of binding post 13.
  • a preferred configuration is where conductive portion 112 of cap 14 is completely enclosed across the top and opening 116 in cap 14 provides test probe access to the top of conductive portion 112 of cap 14.
  • opening 17 is filled with a sealing material to provide a barrier to moisture entry and to prevent corrosion of the binding post and the wire.
  • the sealing material is preferably a gel material having a cone penetration in the range of about 100 to about 350 (10 ⁇ 1mm) and an ultimate elongation of at least 200%.
  • Such preferred sealing materials are disclosed in U.S. Patents 4,600,261 and 4,634,207 to Debbaut.
  • Figures 3A and 3B show the installation of a binding post and terminal cap of this invention on a minimum predetermined size of wire and on a larger wire.
  • cap 14 is screwed down on terminal post 13 whereby the small wire 121 extending through opening means 15 is deformed by edge means 114 of cap 14 whereby edge means 114 makes contact with conductor 122 of wire 121 through the insulation of wire 121.
  • Figure 3A also illustrates how shoulder means 113 in cap 14 engages shoulder means 19 of binding post 13 to thereby stop the advance of cap 14 on binding post 13 before the conductor 122 in wire 121 is severed.
  • the selection of dimensions of the distance between edge means 114 of the cap and shoulder means 113 as well as the dimension between the bottom of opening means 15 and shoulder means 19 of binding post 13 as well as the distance between the bottom of opening means 15 and shoulder 110 of binding posts 13 will all be preselected depending upon the size of wire 121 and the size of conductor 122 in wire 121. These dimensions may also be affected by the lateral distance provided between the skirk of cap 14 and the outer surface of binding posts 13 between shoulder means 19 and shoulder means 110. The wider the gap between the skirt and consequently edge means 114 and the surface of that portion of binding post 13 will provide easier conformability of wire 121 when it is compressed against shoulder 110.
  • edge means 114 will be determined by the characteristics of the preselected wire 121 and conductor 122. If the insulation on wire 121 is hard or tough the edge means 114 may need to be sharp in order to cut through the insulation to make contact with conductor 122. In contrast, if the insulation on wire 121 is soft, edge means 114 may desirably be rounded so that it will pierce through the insulation on wire 121 and make contact with conductor 122 without cutting conductor 122.
  • Figure 3B illustrates the assembly of a larger wire 123 with larger conductor 124 assembled in a binding post 13 and cap 14.
  • edge means 114 has engaged conductor 124 of wire 123 but shoulder means 113 has not contacted or seated on shoulder means 19.
  • the configuration of edge means 114, the distance between the skirt of the cap and edge means 114 from the binding post 13 should be designed such that the edge means 114 will not cut or break conductor 124 when the usual torque is applied by the worker in installing cap 14 on binding post 13.
  • skirt diameter and edge means 114 diameter compared to the binding posts diameter as well as the shape of edge means 114 are such that conductor 123 will be deformed by the downward pressure of cap 14 against shoulder 110 of binding post 13 for the best holding power to prevent wire 123 from being pulled out of the binding post and cap assembly.
  • Edge means 114 of the cap may be configured in a very round shape rather than a cutting edge shape because when edge means 114 contacts the wire 121 or 123 and deforms the wire against shoulder 110 placing the wire under compression a rounded edge means can easily pass through even tough insulation because of the rotational movement of cap 14 in order to make contact with wire 122 or wire 124 while the rounded edge will not be likely to cut or break the conductor 122 or 124 in the wires.
  • Such a rounded configuration of edge 114 is less likely to cause a nick or notch in the conductor of the wire which would weaken it structurally and increase the likelihood that the wire would break at that point.
  • cap 14 can be backed off to open or disconnect the circuit and provide testing capability to isolate sources of problems in the circuit without moving the wire. After testing, the connection can be restored by rotating the cap back into position so that edge means 114 is in contact with the conductor in the wire.
  • FIG. 4 shows a preferred configuration of the terminal block of the present invention wherein housing 132 contains a single tier of terminal posts and caps. Illustrated in Figure 4 is a five pair terminal block having openings 136 in housing 132 for receiving the wires which are desired to be connected with the terminal posts inside housing 132. Caps 134 contain openings 116 for test access to either the conductive inner portion of caps 134 or to the binding posts on which caps 134 are mounted. Base 131 of housing 132 is adapted for attachment to either horizontal or vertical substrates or can be adapted to be plugged into other components. The angle at which the face 133 is positioned provides easier visual access for the worker to install the desired wires in openings 136. The angle at which caps 134 are positioned (essentially perpendicular to face 133) provides easy access for the worker to turn the caps with conventional tools.
  • Figure 5 is a cross-section end view of the preferred embodiment shown in Figure 4 and illustrates that the longitudinal axis 141 of binding posts 143 may be positioned at any desired angle, A, preferably between about 20° and 60° from the vertical. In general, it is preferred that the axis 142 of the openings in the housing and the binding posts in general be perpendicular to axis 141 but these may be positioned at different angles as desired for different applications.
  • Figure 6 illustrates the basic elements of the terminal block adapter of the present invention which comprises collar 221 and cap 222 which are for use on conventional terminal block 21 and threaded binding post 22. It will be noted that in actual use the conventional washers 224 and nuts 222 will preferably be removed from the binding posts and discarded and wire 23 will preferably be cut at the end to provide a straight section of wire with the insulation on the wire for insertion into the collar of the terminal block adapter of the present invention.
  • the terminal block adapter of the present invention involves placing collar 221 on binding post 22 inserting wire 23 into the opening 223 in collar 221 then placing cap 222 into collar 221 and engaging threads in cap 222 on the threads of binding post 22 and tightening cap 222 down on binding post 22 until the bottom edge 224 of cap 222 engages the insulation and cuts through the insulation of wire 23.
  • Cap 222 thus makes the connection through insulation of wire 23 to the conductor in wire 23 through the conductive portion of the cap 222 at edge 224 to binding post 22.
  • Collar 221 has a first opening means 231a which is small in one portion for the binding posts to pass therethrough and is larger in portion 231b for receiving the bottom of the cap 222.
  • Collar 221 contains a second opening 232 extending from the lateral side of the collar into the larger portion 231b of the first opening whereby opening 232 is adapted to receive the insulated wire from the lateral side of the collar 221.
  • Cap 222 comprises an inner conductive portion 233 which has lower edge 224 adapted for engaging the wire and cutting through the insulation of the wire to engage the conductor 23a in wire 23, and outer insulative portion 235.
  • Collar 221 contains a shoulder area 234 which is the bottom of the wider part of the first opening 231b in collar 221. Shoulder area 234 in collar 221 provides the base against which wire 23 is compressed by the bottom edge 224 of cap 222. Collar 221 and cap 222 contain cooperative stop means which stops the advance of bottom edge 224 so that edge 224 of the cap 222 does not sever or cut too deeply into wire 23 and conductor 23a.
  • Such cooperative stop means can be of various configurations and is illustrated in Figure 7 by shoulder area 236 on cap 222 which engages the top surface of collar 221 whereby the distances from the top surface of collar 221 and shoulder 236 to the bottom edge 224 of cap 222 provides a predetermined distance between bottom edge 224 of cap 222 and shoulder means 234 in collar 221 against which wire 23 is compressed by bottom edge 224 of cap 222.
  • Figure 7 Additional optional but preferred aspects of the terminal block adapted of this invention are illustrated in Figure 7 wherein cavity 237 created by skirt 238 on collar 221 is filled with a sealing material which seals around the base of the binding posts 22. Likewise, openings 231a, 231b and 232 in collar 221 may be filled with a sealing material to thereby seal all of the void spaces around the wire and binding post.
  • Figure 7 also illustrates opening 239 and cap 222 which provides a test port to binding post 22 for testing electrical continuity from conductor 23a in wire 23 through the inner conductive portion 233 of cap 222 to binding post 22.
  • port 239 may be filled with a sealing materal and may contain any kind of protective cap or plug to environmentally protect the top of binding post 22.
  • the sealing materials useful in the terminal block adapter of the present invention may be any conventional sealing material such as gels or greases. However, it is preferred that the sealing material be a gel as disclosed in U.S. Patents 4,600,261, 4,634,207, 4,595,635.
  • FIG. 7 Another configuration of the cooperative stop means, while not shown specifically in the drawings, can be understood by reference to Figure 7.
  • An alternative embodiments of the cooperative stop means can be made where the second opening 232 in collar 221 is recessed down in and partially below shoulder 234 whereby bottom edge 224 of cap 222 would engage at least a portion of shoulder 234 opposite opening 232 containing wire 23 thus halting the advance of cap 222 when edge 224 engages the higher portion of shoulder 234 which would occur after edge 224 of cap 222 had engaged wire 23 and passed through the insulation to contact conductor 23a.
  • opening 232 can be extended into the opposite side of collar 221 whereby wire 3 could extend further into opening 232 thereby allowing edge 224 to contact wire 23 on both sides of cap 222 rather than just one side.
  • this invention may also utilize a unilateral stop means in cap 222 which comprises a shoulder similar to shoulder 236 which is a predetermined distance from the edge 224 of cap 222 whereby the shoulder would engage and rest on the flat surface of the insulation of wire 23 after edge 224 has cut through the insulation and engaged conductor 23a.
  • Figure 8 (which uses the same reference numbers as above where applicable) illustrates a collar 241 that may be similar to that illustrated in Figure 7, but has two (and may have more) openings in order that it can be over two (or more) terminal posts, and thus provide means for connection of two (or more) wires to said posts.
  • FIG. 9a A section through line BB is shown in Figures 9a and 9b.
  • the shoulder 234 is of uniform height, and the opening 232 lies above it.
  • a wire in the opening 232 would be cut through if a cap were fully screwed into opening 231b.
  • a portion of collar 234a (generally opposite hole 232a) is positioned higher than the hole 232 so that a cap is prevented from being screwed so far into the opening 231b that severing of the wire would occur.
  • the adapter can be designed to cut away excess length of a wire, and make contact to the length that remains in the adapter.
  • Figure 10 shows a cap partially screwed into an adapter.
  • FIG 11 a terminal block of different design is illustrated.
  • a collar covers three binding posts, two of which are provided with insulating-cutting caps.
