Definitions

  • the present invention relates to an improvement in tools for eifecting telescoping engagement between cooperating parts of an electrical connection.
  • One known type of connector includes a tapered plug terminal, or the like, adapted to frictionally engage a receptacle contact member, usually with one or the other of said members in fixed position.
  • This type of connection is advantageous, particularly where many lead wires are to be attached in a small area.
  • a further object of the invention has been .to provide a terminal-applying tool which may also be employed for disconnecting a terminal from its receptacle in which it is telescopically engaged.
  • terminals often have to be so close together that access to individual connections for repair or replacement is difiicult.
  • taper pin connections engagement between the terminal and receptacle may be so secure that they cannot be separated intact by a direct pull.
  • one of said connector parts is fitted into the tool and thetool pressed axially to give initial telescoping engagement;andadvantageously --the parts are driven into final frictional engagement, with high radial pressure, by an impact of predetermined magnitude.
  • the tool advantageously cushions the applied pressure and applies .a driving force having the requisite direction and magnitude to bring the connector parts into mating; relation; and advantageously when apredetermined force ,for initial insertion has been reached, the .tool automatically ice applies the predetermined energy to drive the parts into final contact relation.
  • a convenient form of hand tool includes a handle and a shank (somewhat like an ordinary screw driver) the end of the shank being formed to receive and engage a terminal connector for axial push and to accommodate a wire extending from the back end of the terminal.
  • my invention provides a tool comprising a spring-pressed plunger and a hammer mounted for longitudinal movement in a holder, said plunger having a terminal-engaging socket at its outer end and a longitudinally extending channel which opens into said socket for accommodating a wire attached to the terminal, and means for engaging a spring through which it engages with said holder and is pressed by said holder into initial engagement with the terminal, a hammer actuating spring is compressed or loaded to a predetermined extent by initial inward movement of the plunger and the hammer is then released to deliver a driving blow through said plunger to the part initially engaged therewith.
  • the socket in the driving .end of said plunger includes wrenching surfaces which fit correspondingly shaped non-circular surfaces of the terminal for application of twisting torque; and said driving end has an overhanging part or lifting flange for engagement with the terminal to pull it away from its engaged connector part.
  • Figure l of the appended drawings i a side view on enlarged scale of a portion of the plunger of a tool embodying the present invention with one form of taper pin terminal and its lead wire shown in dotted lines engaged therewith and-with the free end of the plug in a position to be pressed into a suitable receptacle contact;
  • Figure -2 is a transverse section on the line 22 of Figure 1;
  • Figure 3 is a fragmentary side view with portions in axial section to illustrate more clearly the conformation of the terminal-engaging socket and wire slot;
  • Figure 4 is a central longitudinal sectional view of a plunger, hammerand spring assembly in a holder the end of said plunger corresponding'to that shown in Figure l being broken away;
  • Figure 5 isa transverse section on the line'S-e-S of . Figure. 4.
  • the terminal-engaging plunger of the tool may advantageously push against a spring-driven hammer to load its spring to, a predetermined extent, whereupon the hammer is released to be actuated .by the loaded spring and impact against another part of the plunger.
  • a tool according to the present invention includes a shank 1 which provides at its outer acting end or tool head a terminal-engaging socket 2.
  • The' end of said shank is divided by a'transverse slot 3 into opposed flanges 4'and 5 undercut by the outer end of socket 2 to'fo'rm inwardly directed shouiders 6.
  • the shank 1 also has a longitudinal groove 8 opening into the inner end of socket 2. These together form a continuous open'slot along one side of the shank.
  • - Groove S is open along'a' side of the shank approximately 90 around its axis from the lateral opening of socket 2.
  • the terminal When used for connecting a taper pin terminal 9 into a receptacle contact, the terminal is positioned with its narrow neck portion 11 engaged in slot 3 between flanges .4 and 5 and with its wider insulation-engaging barrel 11 with the necessary force which may be applied by manual pressure on the tool handle, or by impact, or both.
  • the tool just described may also be employed as a puller or extractor for removing a terminal plug from a contact receptacle in which it is frictionally engaged. Where the parts resist separation by a simple pull, the
  • fiat spring 311 secured to one side of hammer 22 in r recess 31, is arranged with its free end extending into recess 27 and bearing against one side of detent 28 which is thus pushed against the opposite side of the bore. in holder as shown in Figures 4 and 6.
  • the other end of detent 2 8 is rounded and extends radially beyond the opening of recess 27 to ride on the inner surface of the bore in holder 20.
  • plunger 16 extends through the hole 22b in hammer part 22a and may have an end'projection V 32 of reduced diameter extending beyond a shoulder- 33 ripheral shoulder portions 15 of barrel 11. Thus, plug 9 is removed without straining the wire 12 or its connection in plug 9.
  • Holder 20 as shown is made in three sections threaded together and has a central longitudinal bore accommodating at its open end the plunger 16 pushed toward its ticular use.
  • a hammer 22 is slidably mounted inthe opposite closed end of said bore and is pushed toward the plunger 16 by a spring 23.
  • a plug 24 screwed into the bore in the lower part of holder 20 serves as an abutment for spring 21 and has a central I opening 25 serving as arbearing to hold plunger 16 to its axial position during sliding movement.
  • the middle section of the holder 20 between said lower section and closed end section has a bore which decreases in diameter toward the upper end so that an annular sloping cam-surface 26 is formed therein.
  • the hammer22 is of diameter slightly less than the narrower portion of the bore so that it may slide freely therein.
  • annular flange 22 at the lower end of said hammer has a which normally engages the detent 28 while said projection 32 extends into hole 29 of said detent.
  • plunger 16 When, with further inward movement of terminal 9, the frictional contact between said parts increases sufliciently, plunger 16 is moved inwardly compressing spring 21, the inner end of said plunger being pressed against detent 28 which moves hammer 22 upward against spring 23.
