Abstract
An improved H-tap compression connector is crimp-connected to a pair of electrical conductors by dies of a crimping tool. The connector includes a connector body having a generalry H-shaped configuration defining a pair of conductor nests opening in 'opposite directions from a transverse axis. The connector includes first and second pairs of spaced-apart crimpable sidewalls extending in opposite directions from the transverse axis. Each pair of sidewalls includes a first sidewall having an inwardly curved distal extent defining a die engagement location and a second sidewall having a die engagement location at the end thereof. The die engagement locations of each of the sidewalls of each pair are located substantially equidistant from the transverse axis. The die engagement location of the curved distal extent of the one sidewall is constructed to have a radius of curvature which is substantially identical to the radius of curvature of the die to prevent rotation of the connector within the dies during crimping.

T&B 1089 PATENT
IMPROVED H-TAP COMPRESSION CONNECTOR
1 FIELD OF INVENTION:
The present invention relates generally to improvements in compression-type connectors for connecting electrical conductors. More particularly, the present invention relates to improvements in an H-Tap electrical connector which permits the connector to be more easily crimped around conductors with a suitable crimping tool.
FACKGROUND OF THE INVENTION:
It is well-known to use compression connectors to connect together two or more electrical conductors. These connectors are typically formed of a suitably conductive and readily deformable material such as copper. Many of these compression type connectors are of the H-Tap variety where the connector body has a generally H-shaped cross section defining upper and lower conductor receiving nests. These connectors further include oppositely directed pairs of deformable sidewalls which further define the conductor receiving nests and which are adapted to be crimped around the conductors supported therebetween. Suitable crimping tools, employing opposed movable dies which are well-known in the art, are used to crimp the H-tap connector around the conductors.
One example of'such an H-tap compression connector is shown is U. S. Patent No. 2,964,585. This patent describes the basic H-tap configuration where the connector includes upper and lower pairs of oppositely extending sidewalls. Each set of sidewalls is capable of being cramped around a conductor. It is noted that the length of the sidewalls of this connector is relatively equal, and the sidewalls do not overlap after crimping. The length of the sidewalls is selected so that the sidewalls do not engage each other during crimping. Such engagement prior to full crimping could result in an ineffective crimp.
Improvements in the basic H-tap compression connector are seen in U. S. Patent No. 3,235,654, where one ._., ~~18~~0 1 of the sidewalls of each pair is provided with a deformable tab at its distal extent. The deformable tab is folded over prior to crimping so that during crimping the sidewalls overlap and the conductor is completely encircled. This avoids the possibility of the 'tips of the sidewalls engaging one another dGring crimping.
Another attempt to provide an H-tap connector which will completely encircle a connector supported in the nest is shown in U. S. Patent No. 5,162,615. The sidewalk of that connector are constructed to have sufficient length to entirely encircle the conductor. I3owever, in order to avoid the problem of the sidewalls engaging one another prior to full crimping, the H-tap of the '615 patent includes one of the sidewalls having an inwardly curved upper extent. During crimping, the inwardly curved extent will cause the one sidewall to deform prior to the other sidewall so that the sidewalls overlap to completely encircle the conductor. However, while permitting the complete encirclement of the conductor, inwardly curving one of the sidewalls presents a problem in positioning the connector between the dies of a crimping tool. Since the inwardly curved portion of one sidewall causes that sidewall to be shorter than the other sidewall, the dies of the crimping tool will not evenly engage both sidewalk of the connector at the same time. This causes the connector to twist or rotate within the dies of the tool during crimping, rendering proper termination more difficult. Movement of the connector within the dies could present a significant problem where long lengths of very large cable are to be connected.
It is, therefore, desirable to provide an H-tap compression connection which permits the reliable overlapping of the sidewalls of the connector during crimping and which may be readily supported within the dies of the crimping tool.

Figure 4 shows the compression connector of Figure 1 crimped about a pair of electrical conductors.
DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT:
Referring to Figures 1 and 2, an H-tap compression connector 10 of the present invention is shown. Connector 10 is formed of a suitably conductive metal such as copper and is cut from an extruded length. Copper is selected as a preferred material as it exhibits high electrical conductivity and sufficient ductal characteristics so as to be readily crimped by the dies of a conventional crimping tool. Other suitable conductive metals, such as aluminum may also be employed. Further, other forming techniques, such as casting, may also be used °to form the connector of the present invention.
As shown in Figure 1, connector 10 has a generally H-shaped cross section providing upper and lower conductor receiving nests 12 and 14. Nests l2 and 14 are separated by cross member 16, which generally lies along transverse axis t (Fig. 3). Conductor receiving nest 12 is defined by a bottom wall 18 and a pair of upstanding sidewalls 20 and 22.
Likewise, nest 14 is defined by a bottom wall 24 and opposed sidewalls 26 and 28, which extended in a direction opposite that of sidewalls 20 and 22.
The site and shape of connector 10 may be varied to accommodate various thicknesses of electrical conductors.
The length of sidewalls 20, 22, and 26, 28 are selected such that when conductors are placed respectively in nests 12 and 14 and suitably crimped, each set of sidewalls 20, 22 and 26, 28 will overlap to encircle the conductor supported therein (Fig. 4). In order to permit the controlled overlap of each set of sidewalls, one sidewall of each pair is 1 modified so that it will deform prior to the deformation of the other sidewall to thereby permit such overlap.
As shown in Figure 1, diagonally opposed sidewalls 22 and 26 include curved distal extents 22a and 26a, respectively. Each curved distal extent 22a and 26a is inwardly curved toward the opposite sidewall 20, 28 of each pair. The other set of diagonally opposed sidewalls 20 arid 28 have distal end extents 20a and 28a, which remain straight. As will be described in further detail l0 hereinbelow, the curved distal extents 22a and 26a of sidewalls 22 and 26 permit those sidewalls to deform prior to opposite sidewalls 20 and 28 during crimping so that sidewalls 20 and 28 will overlap sidewalls 22 and 26 upon crimping.
Referring to Figure 3, connector 10 is shown positioned between dies 30 and 32. Dies 30 and 32 are conventional crimping dies which may be housed in the head of a crimping tool (not shown). Tools such as these are commonly used to effect crimp connection of electrical conductors in connector 10. In operation, connector 10 is placed between dies 30 and 32. At this stage, typically, conductors (Fig. 4) are supported within nests 12 and 14 of connector 10. Dies 30 and 32 are brought together by actuation of the crimping tool (not shown) to engage sidewalls 20, 22 and 26, 28. Further movement of dies 30 and 32 causes sidewalls 20, 22 and 26, 28 to crimp around the conductors supported within nests 12 and 14.
In many connectors of the prior art, especially where it is necessary to assure complete encirclement of the ,,30 conductors by the crimped sidewalls, the length of the sidewalls of the pair are constructed to be unequal. Thus, the longer sidewall of the pair would engage the dies prior to the shorter sidewall. As dies 30 and 32 have curved inner connector engaging surfaces 34 and 36 respectively and as uniform crimping pressure is applied to both ends of connector 10, there would be a tendency for the connector to turn or rotate within the dies. Such rotation renders 21~~~4~

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT:
Referring to Figures 1 and 2, an H-tap compression connector 10 of the present invention is shown. Connector 10 is formed of a suitably conductive metal such as copper and is cut from an extruded length. Copper is selected as a preferred material as it exhibits high electrical conductivity and sufficient ductal characteristics so as to be readily crimped by the dies of a conventional crimping tool. Other suitable conductive metals, such as aluminum may also be employed. Further, other forming techniques, such as casting, may also be used °to form the connector of the present invention.
As shown in Figure 1, connector 10 has a generally H-shaped cross section providing upper and lower conductor receiving nests 12 and 14. Nests l2 and 14 are separated by cross member 16, which generally lies along transverse axis t (Fig. 3). Conductor receiving nest 12 is defined by a bottom wall 18 and a pair of upstanding sidewalls 20 and 22.
Likewise, nest 14 is defined by a bottom wall 24 and opposed sidewalls 26 and 28, which extended in a direction opposite that of sidewalls 20 and 22.
The site and shape of connector 10 may be varied to accommodate various thicknesses of electrical conductors.
The length of sidewalls 20, 22, and 26, 28 are selected such that when conductors are placed respectively in nests 12 and 14 and suitably crimped, each set of sidewalls 20, 22 and 26, 28 will overlap to encircle the conductor supported therein (Fig. 4). In order to permit the controlled overlap of each set of sidewalls, one sidewall of each pair is 1 modified so that it will deform prior to the deformation of the other sidewall to thereby permit such overlap.
As shown in Figure 1, diagonally opposed sidewalls 22 and 26 include curved distal extents 22a and 26a, respectively. Each curved distal extent 22a and 26a is inwardly curved toward the opposite sidewall 20, 28 of each pair. The other set of diagonally opposed sidewalls 20 arid 28 have distal end extents 20a and 28a, which remain straight. As will be described in further detail l0 hereinbelow, the curved distal extents 22a and 26a of sidewalls 22 and 26 permit those sidewalls to deform prior to opposite sidewalls 20 and 28 during crimping so that sidewalls 20 and 28 will overlap sidewalls 22 and 26 upon crimping.
Referring to Figure 3, connector 10 is shown positioned between dies 30 and 32. Dies 30 and 32 are conventional crimping dies which may be housed in the head of a crimping tool (not shown). Tools such as these are commonly used to effect crimp connection of electrical conductors in connector 10. In operation, connector 10 is placed between dies 30 and 32. At this stage, typically, conductors (Fig. 4) are supported within nests 12 and 14 of connector 10. Dies 30 and 32 are brought together by actuation of the crimping tool (not shown) to engage sidewalls 20, 22 and 26, 28. Further movement of dies 30 and 32 causes sidewalls 20, 22 and 26, 28 to crimp around the conductors supported within nests 12 and 14.
In many connectors of the prior art, especially where it is necessary to assure complete encirclement of the ,,30 conductors by the crimped sidewalls, the length of the sidewalls of the pair are constructed to be unequal. Thus, the longer sidewall of the pair would engage the dies prior to the shorter sidewall. As dies 30 and 32 have curved inner connector engaging surfaces 34 and 36 respectively and as uniform crimping pressure is applied to both ends of connector 10, there would be a tendency for the connector to turn or rotate within the dies. Such rotation renders 21~~~4~
1 crimping difficult and could result in an ineffective crimp connection in certain situations.
The present invention permits crimping of an electrical connector which will completely encircle 'the conductor supported therein without the connector rotating or turning duiing crimping. As shown in Figure 3, one technique to prevent the rotational movement of connector l0 within dies 30 and 32 is to provide a die engagement surface 27 at the curved distal extent 26a of sidewall 26 for engagement with the connector engagement surface 36 of the die.
Referring to the lower half of connector 10 shown in Figure 3, die 32 is configured to have a die engagement surface 36, which has a given radius of curvature noted in Figure 3 as rf. The die engagement surface 27 of curved distal extent 26a is constructed to have a substantially similar radius of curvature rz. Thus, curved distal extent 26a engages curved die engagement surface 36 along an arcuate length. This reduces the tendency of rotational movement of connector 10 within dies 30 and 32 during crimping.
A further technique to prevent the rotational movement of connector 10 within dies 30 and 32 is to provide die engagement extents on each sidewall of the pair which engage the curved connector engagement surface of the dies at the same time during crimping. Referring to the upper half of the drawing of Figure 3, inwardly curved distal extent 22a of sidewall 22 defines a die engagement location 23, which lies proximate of the outer tip 25 thereof. Die engagement location 23 of sidewall 22 is located a distance 1~ measured perpendicularly from transverse axis t.
Similarly, sidewall 20, which is substantially straight, includes a die engagement location 21 at the tip thereof.
Die engagement location 21 is spaced a distance 1z measured perpendicularly from transverse axis t. Connector 10 is constructed such that 1~ is approximately equal to 1Z so that upon actuation of dies 30 and 32, connector engagement ~~2~s~o 1 surface 34 will engage die engagement locations 23 and 21 simultaneously thereby preventing rotational movement of connector 10 between dies 30 and 32.
As may be appreciated, since opposite longitudinal ends of connector 10 include in the preferred embodiment identically formed sidewalls diagonally opposed to one another, the combined operation of the above described features will significantly reduce if not eliminate the tendency of the connector 10 to turn or rotate within dies 30 and 32 during crimping.
The present invention includes an additional feature which facilitates crimping about conductors.
Opposite transverse ends of cross member 16 include inwardly recessed dimples 40 and 42.
Referring now to Figures 1 and 4, dimples 40 and 42 will lessen the material located at the ends of cross member 16 so that connector 10 will more easily deform between dies 30 and 32 upon application of a crimping force.
Figure 4 shows a pair of conductors 44 and 46 crimped within nests 12 and 14 of connector 10. Sidewall 20 of connector l0 is shown overlapping sidewall 22, which is deformed prior to the deformation of sidewall 20 due to inwardly curved distal extent 22a. Thus, conductor 44 is completely encircled by sidewal k 2o and 22. In a similar manner, conductor 46 is completely encircled by sidewalls 26 and 28 as sidewall 28 overlaps sidewall 26.
While a connector having identical sidewal k on each side of transverse axis t is shown, the present invention may also be employed with nests 12 and 14 being defined by different sized sidewalls. Thus, connector 10 would be able to accommodate a pair of conductors having different cross sections.
Various changes to the foregoing described and shown structures would now be evident to those skilled in the art. Accordingly, the particularly disclosed scope of the invention is set forth in the following claims.
The present invention permits crimping of an electrical connector which will completely encircle 'the conductor supported therein without the connector rotating or turning duiing crimping. As shown in Figure 3, one technique to prevent the rotational movement of connector l0 within dies 30 and 32 is to provide a die engagement surface 27 at the curved distal extent 26a of sidewall 26 for engagement with the connector engagement surface 36 of the die.
Referring to the lower half of connector 10 shown in Figure 3, die 32 is configured to have a die engagement surface 36, which has a given radius of curvature noted in Figure 3 as rf. The die engagement surface 27 of curved distal extent 26a is constructed to have a substantially similar radius of curvature rz. Thus, curved distal extent 26a engages curved die engagement surface 36 along an arcuate length. This reduces the tendency of rotational movement of connector 10 within dies 30 and 32 during crimping.
A further technique to prevent the rotational movement of connector 10 within dies 30 and 32 is to provide die engagement extents on each sidewall of the pair which engage the curved connector engagement surface of the dies at the same time during crimping. Referring to the upper half of the drawing of Figure 3, inwardly curved distal extent 22a of sidewall 22 defines a die engagement location 23, which lies proximate of the outer tip 25 thereof. Die engagement location 23 of sidewall 22 is located a distance 1~ measured perpendicularly from transverse axis t.
Similarly, sidewall 20, which is substantially straight, includes a die engagement location 21 at the tip thereof.
Die engagement location 21 is spaced a distance 1z measured perpendicularly from transverse axis t. Connector 10 is constructed such that 1~ is approximately equal to 1Z so that upon actuation of dies 30 and 32, connector engagement ~~2~s~o 1 surface 34 will engage die engagement locations 23 and 21 simultaneously thereby preventing rotational movement of connector 10 between dies 30 and 32.
As may be appreciated, since opposite longitudinal ends of connector 10 include in the preferred embodiment identically formed sidewalls diagonally opposed to one another, the combined operation of the above described features will significantly reduce if not eliminate the tendency of the connector 10 to turn or rotate within dies 30 and 32 during crimping.
The present invention includes an additional feature which facilitates crimping about conductors.
Opposite transverse ends of cross member 16 include inwardly recessed dimples 40 and 42.
Referring now to Figures 1 and 4, dimples 40 and 42 will lessen the material located at the ends of cross member 16 so that connector 10 will more easily deform between dies 30 and 32 upon application of a crimping force.
Figure 4 shows a pair of conductors 44 and 46 crimped within nests 12 and 14 of connector 10. Sidewall 20 of connector l0 is shown overlapping sidewall 22, which is deformed prior to the deformation of sidewall 20 due to inwardly curved distal extent 22a. Thus, conductor 44 is completely encircled by sidewal k 2o and 22. In a similar manner, conductor 46 is completely encircled by sidewalls 26 and 28 as sidewall 28 overlaps sidewall 26.
While a connector having identical sidewal k on each side of transverse axis t is shown, the present invention may also be employed with nests 12 and 14 being defined by different sized sidewalls. Thus, connector 10 would be able to accommodate a pair of conductors having different cross sections.
Various changes to the foregoing described and shown structures would now be evident to those skilled in the art. Accordingly, the particularly disclosed scope of the invention is set forth in the following claims.
