w~re insertion ram 6~ received in the slot 56, is joined to the yoke member 52 by means of a removable pin 66 which can be p~ssed through either of the bores 58 or G0 and through the appropri.ate ~ore 68 or 70 in the rarn 64. The bottom of the ram 64 is formed with a recess 72, the leading end 74 of the r~n 6 being shaped ~or engaging a wire to clrive it into the wire-recei.ving slot of a t-erminal of the connector 78. r~he yoke member 52 also has a pin 76 whi.ch depends through the bore 62 into the slot 42 of the plate 40. A ram and wire guide plate 81 secured t:o the head 18 is provi.ded wlth a vert~cal wire slot 82 at its forward end.
In operation, a connector -/8 is inserted into the slot 30, as shown in Fi~ure 1, so that the tooth 48 of the pawl 45 enga~es in a desired one of l:he s1-.ts 77 i:~ the housing of the connecto.r 73, and a . ~; ~

Repeated actuation of the lever 14 causes the connector to be indexed step-~by-step hrough the tcol so that wires inserted sequentially into the slot 82 can each be connected to one of the termlnals Vll that side of thc connector ~hich faces the ram G4.
, , ~89 ', Si.nce the connector 78 has two opposite rows of terminals it must be passed through the tool twice in order to connect wires to the terminals of each row.
The tool can also be adapted for use with a narrower connector (not shown) having only a single' row of terminals, by placing an insert 84, Fig-ure 7, in the groove 30 to reduce the width thereof sufficiently to cause the narrower connector to fit snugly in the groove 30. In this case the pawl 32 is ~,o replaced by a pawl 32' of a greater length than ~he ,' pawl 32 and which extends through an opening 85 in the insert 84. In oxder to adjust the tool to ' accommodate an electrical connector havi.ng a different '~ centre~to~centre spacing between the terrninals o~ the or each row, it is only necessary to remove t~le pin 6~ and realign it with the appxopxiate hore 58 or 60 in the ~oke member 52 and the appropriate bore 1 6~ or 70 in the insertion membe.r 64.
i According to Figure 4, the pi.n 66 is positioned in the bores 58 and 68, and according to Fi~uxe ~, the pin 66 i5 positioned in the bores G0 and 70 whereby the travel o~ ram 64 and thus of the pin 3fi is increased by a length L.

A hand tool for successively connecting wires to respective electrical terminals arranged in a row extending along a housing of an electrical connector, the tool comprising a wire insertion head, defining a connector guideway, a wire insertion ram, means for driving the ram towards and away from the guideway transversely of the length thereof, and means connected to the ram for advancing the connector step by step along the guideway to bring each terminal in turn into alignment with the ram to allow the ram to connect a wire to the terminal, wherein the connector advancing means comprises a cam plate formed with a cam slot extending transversely of the path of movement of the ram and receiving a camming pin which is fixed with respect to the ram, the cam plate carrying a connector advancing pawl arranged to be spring biased into engagement with the connector, the cam plate being drivable by the ram transversely of the path of movement thereof.
2. A tool according to Claim 1, wherein the cam plate is slidably mounted in a recess in the insertion head, the cam slot being remote from the pawl and the pin projecting into the recess through an opening in the insertion head.
3. A tool according to Claim 1, wherein the ram is received in a yoke member connected to a ram drive shaft, the camming pin extending from the yoke member, a connecting pin being insertable into first bores or alternatively into second bores, in the yoke member and ram, to connect the ram to the yoke member, the first bores being spaced from the second bores lengthwise of the path of movement of the ram.
4. A tool according to Claim 3, wherein the ram is received in an axial channel in the yoke member, the camming pin being slidably received in an opening in the bore of the channel, the first and second bores comprising bores formed in the walls of the channel and through bores in the ram.
5. A tool according to Claim 1, 2 or 3, wherein the pawl is mounted in a recess in the cam plate and is parallel therewith, a biasing spring for the pawl also being mounted in the recess.
6. A tool according to Claim 1, wherein a spring loaded ratchet stop projects from a side wall of the guideway, which is remote from the ram, in substantial alignment with the pawl.
7. A tool according to Claim 6, wherein an insert is positioned in the guideway against: that said remote side wall thereof to, reduce the width of the guideway, the ratchet stop protruding through an opening in the insert.
8. A tool according to Claim 1, wherein the pawl projects perpendicularly from the cam plate through an opening in a cover plate provided between the cam plate and the ram.
9. A tool according to Claim 8, wherein the guideway is defined by the cover plate and by a guideway member, detachably connected to the insertion head.
10. A tool according to Claim 1. or 2, wherein the cam plate is mounted on roller bearings having rotational axes extending at right angles to the length of the guideway and to the path of movement of the ram.
