Definitions
- the present invention relates to improvements in methods of and tools for making an electrical connection between an electrical terminal and a contact wherein one part provides a recess which receives and frictionally engages a plug portion of the other part.
- One known type of such a 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.
- An object of the present invention has been to provide an implement or tool for connecting these parts in a manner to insure optimum mechanical and electrical engagement between them without injury to or impairment of either.
- a further object has been to provide a tool by which one part, as a terminal attached to wire end, may while held by the tool be teleseoped and frictionally engaged with a receptacle contact member quickly and securely in a simple operation even where the available working space is limited and the parts are not otherwise readily accessible.
- a further object of the invention has been to provide a method and a tool whereby, in operation, a tell-tale marking, or the like, is left on one of the parts automatically, thus indicating that they have been joined under optimum conditions for producing an effective and durable connection.
- 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 or groove at its outer end 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, and 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. Where the driving face of the plunger carries an appropriate die or dies, this blow also leaves a mark on the connector.
- Figure l of the appended drawings is a central longitudinal sectional view of a plunger, hammer and spring assembly in a holder with the outer end of the plunger broken away;
- Figure 2 is a view in perspective on enlarged scale of the socket or grooved end portion of the plunger
- Figure 3 is an outer end elevation of the socket portion of the plunger shown in Figure 2;
- FIG 4 is a fragmentary bottom plan view of the socket portion of the plunger shown in Figure 2;
- Figure 5 is a fragmentary top plan view with the socket portion of the plunger shown as about to engage the shoulder of a receptacle type terminal;
- Figure 6 is a view similar to Figure 5 of the socket portion about to engage the shoulder of a plug type terminal.
- the invention may be embodied in a simple screw-driver-like tool, e.g., by rigidly securing a suitable head on a shank or hand grip
- the present invention is advantageously embodied in a hand tool which utilizes the operating mechanism, as in Figure 1, of a commercially available self-triggering nail set or center punch-but with the outer end of the operating plunger specially designed and constructed as shown in Figures 2, 3 and 4 and hereinafter described.
- 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 a terminalengaging socket or groove 2 open at its outer end.
- the outer end of groove 2 presents a flared opening defined in part by inclined driving faces 3 each of which has a marking die 4 extending beyond its surface.
- Groove 2 is advantageously formed at its upper end with a rounded tapering surface 5 providing a guide way for a wire 6 to Patented Dec. 6, 1960 which is attached a terminal, as 7, Figure 5, or 8, Fig ure 6.
- the terminal When used for connecting a terminal and a receptacle, the terminal is positioned with its insulation engaging portion engaged in groove 2 and with its shoulder portion 11, 11a between driving faces 3 and dies 4.
- the wire 6 extends thence into and along groove 2.
- the outer end of the terminal is engaged with a contact, as plug 12 or receptacle 12a, which are telescoped together with the necessary force applied by manual pressure on the tool handle, or by impact, or both.
- a holder 14 for plunger 13, as shown, is made in three sections threaded together and has a central longitudinal bore accommodating at its open end the plunger 13 pushed toward its grooved end by a spring 15.
- a hammer 16 is slidably mounted in the opposite closed end of said boreand is pushed toward the plunger 13 by a spring 17.
- a plug 18 screwed into the bore in the lower part of holder 14 serves as an abutment for spring and has acentral opening 19 serving as a bearing to hold plunger 13 toits axial position during sliding movement.
- the middle section of the holder 14' between said lower section and the closed end section has a bore which decreases in diameter toward the upper end so that an annular, sloping cam surface 20 is formed therein.
- the hammer 16 is of a diameter slightly less than the narrower portion of the bore so that it may slide freely therein.
- An annular flange 16a at the lower end of said hammer has a free sliding fit in the lower or larger portion ofsaid bore, the lower end of the hammer having a central hole 16b.
- Hammer 16 also has a transverse recess 21 (Figure 1) which receives a slidable detent 22 provided with an axial hole 23 slid'ably fitted to the upper shaft of plunger 13.
- a flat spring 24, secured to one side of hammer 16 in recess 25, is arranged with its free end extending into recess 21 and bearing against one side of detent 22 which is thus pushed toward the opposite side of the bore in holder 14 as shown in Figure 1.
- the other end of de tent 22 is rounded and extends radially beyond the opening of recess 21 to ride on the inner surface of said bore in holder 14.
- plunger 13 extends through the hole 165 in hammer part 16 and may have an end projection 26 of reduced diameter extending beyond a shoulder 27 which normally engages the detent 22 while said projection 26 extends into hole 23 of said detent.
- the character of the dies 4 will be such as to, leavea sensible mark on the material of the struck part by a blow which effects optimum connection between the parts;
- terminal connecting and marking tools described above are well suited to attain the ends and objects herein directly and indirectly set forth; that they can be manufactured by conventional techniques; and that the various features and arrangements of parts can be modified readily so as best to suit a particular use.
- Certain features of the dis closure may be used to advantage in particular applications without a corresponding use of other features, and the disclosure may be used to advantage in particular applications without a corresponding use of other features, and the elimination or modification of such features is to be construed as within the scope of this invention unless specifically excluded by the following claim or required by the scope of the prior art;
- a tool For use in installing a connected lead wire and tapered connector having lateral driving abutments intermediate its length in mechanically-wedged electrical connection with a mating connector part, a tool including a plunger mounted to slide endwis'e inwardly in a recessed handle initially to load a spring enclosed therein and means for impact driving said plunger in the opposite direction when said spring is released from loaded condition after predetermined inward movement of said plunger, the outer part of said plunger relative to said handle providing an axially extending shank having an axially disposed longitudinal connector-engaging groove therein, said groove at one end opening through the end of said shank to define divergent driving faces at the end surfaces of the groove sidewalls adapted to drivingly engage said abutments, and a guideway at the other end of the groove adapted for engaging a connected portion of the lead wire of the connector whereby the connector and adjacent lead wire portions are maintained in axial alignment along said shank in position for installation with the lateral driving parts abutted against said driving faces.
