Definitions

  • This invention is directed generally to the field of compression tools and more particularly to a compression tool for compressing or crimping generally tubular workpieces such as connectors or terminals utilized for establishing electrical wiring connections.
  • wire sizes and corresponding connector or terminal sizes vary over a considerable range for achieving different wire gauge connections.
  • the outer diameters to be compressed or crimped may range from as small as 1/4" to as large as 2".
  • the former type of tool can be rather difficult and time- consuming to use, as the removable, interchangeable diesets must be frequently changed in the field, whenever different sized wires and the corresponding connectors or terminals are to be installed.
  • the latter type of tool is generally referred to as a "dieless" compression tool.
  • dieless refers to the single, permanent die or compressing structure which is utilized, rather than the multiple, interchangeable, removable diesets provided with the former type of tool.
  • Tools of this latter type have heretofore proven relatively heavy and complex, and have been relatively difficult to operate. Moreover, many of these latter tools are prone to frequent malfunction due to the complexities of their design.
  • the tools of the second type have generally provided an indentor-type of crimp, which is a crimp or compression centered about a single indentation, made by the tool, in the terminal or connector.
  • an indentor-type of crimp which is a crimp or compression centered about a single indentation, made by the tool, in the terminal or connector.
  • a polygonal and preferably, a hexagonal configuration of compression or crimping is generally regarded as superior in achieving both electrical and mechanical union of such a connector or terminal with electrical wires.
  • a more specific object is to provide a compression tool of the foregoing type which is capable of accommodating a relatively broad range of connector or terminal sizes.
  • a related object is to provide a compression tool of the foregoing type which provides a polygonal compression configuration to the connector or terminal compressed.
  • a further object is to provide a compression tool of the foregoing type which is relatively simple in its design and operation and yet is highly reliable in operation.
  • a compression tool comprises a tool head having a through opening, a plurality of movable compressing members carried by said tool head, a stationary compression surface carried by said tool head and opposingly facing said plurality of movable compressing members, means carried in said tool head for defining a maximum compressing position for each of said plurality of compressing members, said maximum compressing positions generally increasing in a predetermined sequence from one end of said tool head through opening toward the other end of said tool head through opening and ram means for driving said plurality of compressing members towards their respective maximum compressing positions.
  • a compression tool in accordance with the present invention is designated generally by the reference number 10.
  • This compression tool 10 includes a tool head designated generally by the reference numeral 12 and a manually controlled tool actuating portion designated generally by the reference numeral 14.
  • This latter manual actuating portion 14 comprises a pair of handles 16, 18, the handle 16 being movable relative to the stationary handle 18 which is rigidly coupled with the tool head 12.
  • the interior portion of handle 18 carries conventional hydraulic apparatus (not shown) which forms no part of the invention. Suffice it to say that this hydraulic apparatus is arranged for actuating the compression mechanism of the tool carried in the tool head 12.
  • This tool head 12 generally comprises a housing 20 having a through aperture 22 for receiving at an open end 23 thereof a connector or terminal 24 (shown in phantom line) which is to be crimped or compressed.
  • the head 12 carries a plurality of generally parallel, spaced apart movable compressing members or dies, designated collectively by the reference numeral 26.
  • These parallel dies 26 are generally perpendicular to the axis of the through aperture 22.
  • these compressing members or dies 26 are permanently mounted in the head 12, and as will be more fully explained hereinbelow, are arranged for compressing or crimping terminals or connectors 24 over a relatively broad range of sizes. This novel arrangement avoids the necessity of providing a plurality of interchangeable, removable sets of dies as in many heretofore known compression tools.
  • the tool head 12 also carries a stationary compression surface 28 which opposingly faces the movable compressing members or dies 26. In operation, these movable compressing members 26 cooperate with the stationary compression surface 28 to impart the desired compression or crimping configuration to terminals or connectors such as the terminal 24. This compression achieves a mechanical and electrical connection of the terminal or connector 24 to wire conductors such as a wire bundle 30, indicated in phantom line.
  • the movable compressing members or dies are carried in a plurality of guide channels 32, 34, 36, 40, 41 and 42.
  • seven of these movable compressing members or dies 26 are consecutively indicated by the reference characters 26-1 through 26-7, inclusive.
  • these movable compressing members or dies 26-1 through 26-7, inclusive are mounted for slidable movement within the respective guide channels 32 through 42, inclusive.
  • a novel arrangement is provided for defining a maximum compressed position for each of the movable compressing members or dies 26. Clearance is provided for the advancing dies 26 by a plurality of slots or indentations, indicated in Fig. 2 collectively by the reference numeral 44, and formed in the stationary compression surface 28. As viewed in Figs. 3, 4 and 6, these slots or indentations 44 are consecutively indicated by reference characters 44-1 through 44-6, corresponding respectively to the dies 26-1 through 26-6.
  • these indentations or slots 44 are of successively greater extent or depth with respect to the surface 28, thereby defining successively increased clearances during compression for their corresponding, opposed movable compressing members or dies 26.
  • the tool head 12 carries a channel 48 which slidably mounts a ram 50.
  • the channel 48 and particularly a sidewall surface 47 thereof, is formed at an angle or on a bias with respect to the parallel compressing members 26 such that a progressive offset of the ram 50 with respect to the dies 26 is experienced as it advances in the channel 48.
  • the ram 50 is further formed with a die-engaging surface 52 which is formed at a further angle with respect to the channel 48. This latter angle of the die-engaging surface 52 is such that it is substantially perpendicular to the movable compressing members or dies 26 throughout the range of travel of ram 50 within the channel 48.
  • the channel 48 has an upper stop surface 49 defining maximum advancement of the ram 50.
  • this stop surface 49 and the sidewall surface 47 define the effective maximum advancement of the ram 50 with respect to the dies 26 and hence the maximum compression of the dies 26.
  • this maximum compression of the dies 26 becomes progressively greater for successive dies 26-1, 26-2, etc., as viewed from right to left in Figs. 2, 3 and 6.
  • This ram 50 is actuated by means of a shaft 51, which is responsive to the hydraulic drive (not shown) carried in the handle 18, upon manual actuation of the handle 16, as discussed above.
  • the increasing offset of the die-engaging surface 52 thereof will result in compression of progressively fewer of the movable compressing members or dies 26, as viewed from right to left in Figs. 2, 3 and 6. Accordingly, progressively fewer of the movable compressing members or dies 26 are retained in compression as the ram 50 advances the dies 26 upon successively smaller terminals or connectors. Conversely, as terminals or connectors of greater diameter or size are introduced into the channel 22, a greater number of the compressing members or dies 26 remain activated by the ram 50. Consequently, the novel structure of the ram 50 and its channel 48 defines progressively increasing degrees or extents of maximum compression for the successive dies 26-1 through 26-6, as indicated by the arrows 55-1 and 55-6 in Fig. 2.
  • FIG. 3 and Fig. 4 the tool head 12 is illustrated in operation, compressing or crimping a relatively large terminal or connector member 24a to achieve the compressed or crimped configuration thereof generally as illustrated in Fig. 5.
  • the movable compressing members or dies 26 and stationary compression surface 28 cooperate to form a regular polygon, so as to impart substantially a regular polygonal appearance to the terminal or connector 24a (as best viewed in Fig. 5).
  • this configuration of the movable compressing members or dies 26 and stationary compression surface 28 surroundingly engages the terminal or connector 24 so as to impart some degree of compression substantially continuously about the periphery thereof.
  • Such continuous peripheral compression results in a reliable mechanical and electrical interconnection thereof with the wire bundle 30 carried therein.
  • each of the movable compressing members or dies 26 presents a substantially concave working or compression surface 54, defined by a pair of upstanding sidewalls 56, 58.
  • this concavity defines a regular hexagon.
  • the indentations or slots in the stationary compression surface 28 are formed with a complementary convex configuration to receive the concave compression surface 54 of the respective movable compressing members or dies 26-1, etc.
  • the slots 44-1, 44-2, etc. have successively increasing depths at the lateral side portions thereof, which correspond generally to the upstanding sidewall portions 56, 58 of the movable compressing members or dies 26.
  • the guide channels 32, 34, etc. are defined in the illustrated embodiment by means of a plurality of side-wall partition members 60, 62, which are interposed between respective movable compressing members or dies 26-1, 26-2, etc.
  • a plurality of side-wall partition members 60, 62 which are interposed between respective movable compressing members or dies 26-1, 26-2, etc.
  • reference numerals 62, 64, 66, 68 and 72 one of each of these pairs of partitions.
  • a substantially smaller terminal or connector member 24b is illustrated under compression by the movable compressing members or dies 26-2 through 26-6, inclusive.
  • the dies 26-1 and 26-2 have reached their maximum compressed positions as defined by the ram 50 and are no longer engaged by the surface 52. thereof and hence do not compress the workpiece 24b.
  • the next succeeding dies 26-3 and 26-4 substantially reach their fully compressed positions as defined by the increased advancement of the ram 50 toward its stop surface 49 and impart the desired compression since these slots 44-3 and 44-4 are deeper than the slot 44-2.
  • the die 26-4 in its cooperating receiving slot or indentation 44-4 are also illustrated in section in Fig. 7.
  • the remaining dies 26-5 and 26-6 enter their respective indentations or slots 44-5 and 44-6 to some degree while compressing the workpiece 24b, but do not become fully advanced or compressed with respect to the slots 44-5 and 44-6.
  • a second embodiment of the tool head 12 is generally designated by the reference numeral 12a.
  • the tool head 12a is designed for the splicing or joining of a pair of wires or cables by means of a splicing connector 24b, as best seen in Fig. 10.
  • the tool head 12 comprises an upper half or portion 110 and a lower half or portion 112.
  • a stationary compression surface designated generally by the reference numeral 28a, which is substantially identical to the stationary compression surface 28 illustrated and described above with reference to the preceding Figs. 1 through 8.
  • this compression surface 28a is formed with a plurality of slots or indentations (not seen in Figs. 9-11) which are substantially identical to the slots or indentations 44, illustrated and described above with reference to Figs. 1 through 8.
  • the lower half or portion 112 of the tool head 12a is substantially identical in configuration to the lower half or portion of the tool head 12 as illustrated in Figs. 1 through 8 above.
  • the portion 112 carries a plurality of slidably mounted dies 26a, mounted for reciprocation in response to movement of a ram (not shown) mounted at an offset or angle in a channel (not shown).
  • a ram not shown
  • a channel not shown
  • the upper tool head half 110 has a castellated configuration on the opposing surfaces thereof and facing the lower tool head half 112.
  • the lower tool head half 112 has a complementary castellated configuration at its opposing side surfaces which face the upper tool head half 110.
  • These castellated surfaces of the tool head halves 110, 112 advantageously interfit to define the assembled tool head 12a, as best viewed in Figs. 10 and 11.
  • through apertures 116, 118 are provided in the raised portions of the castellated side walls of the lower tool head .half 112 and similar through apertures 116a, 118a are provided in the castellated sidewalls of the upper tool head half 110.
  • through apertures 116 and 116a as well as the similar through apertures 118 and 118a are respectively in alignment when the upper tool head half 110 is assembled with the lower tool head half 112.
  • a pair of pins 120, 122 are insertable through the respective aligned through apertures 116, 116a and 118, 118a.
  • one of the pins 120, 122 may be non-removably retained in its receiving apertures 116, 116a or 118, 118a, thereby effectively forming a hinged joint between the upper and lower tool head halves 110, 112.
  • the other of the two pins 120, 122 may then be provided as a removable pin, to allow opening and closing of the tool head 12a about the connector 24b for facilitating splicing of a pair of wires 30b, 30c (see Figs. 10 and 11).
  • hinged tool head 12a thus permits splicing of a pair of wires utilizing a splicing connector 24b, in addition to the attachment of a terminal 24 to a single wire or cable 30, as illustrated and described above in connection with Figs. 1 through 8.
