When the frame member 46 is moved forward by the ram 30, an electrical connector can be crimped between the two opposing indentors 42, 45. At the same time, the jaws 48 are wedged in an inward direction towards each other. This causes the second and third indentors 43, 44 to be moved inward towards each other to also crimp the electrical connector by the indentors 43, 44. Thus, the electrical connector is indented at four points by the four indentors 42-45.
In some circumstances, the electrical connector can be mis-crimped if the electrical connector is not properly centered relative to the four indentors 42-45. This could result in a failure of the working head 12. If the misalignment is not noticed by the user, and the user continued to operate the tool 10, the head 12 could become severely damaged and might not be able to function anymore.
The foregoing and other problems are overcome, and other advantages are realized, by the use of the exemplary embodiments of this invention.

The guides 106 each comprise a one piece guide member 110, preferably made from clear plastic material, such as LEXAN®, and fasteners 112. However, in an alternate embodiment, the guide members could be made from a different type of material, such as sheet metal for example. The guide member (or main section) 110 has a general flat plate-like shape with a connector receiving slot 114. The slot (or connector receiving portion) 114 extends through a thickness of the main section 110 and has an entrance (or open end) at the slot 104. The entrance, or open end, may be between edges 115, 117 of the main section 110. The slot 114 also has a closed end 116 at the connector receiving area 74 (wherein the slot 114 is aligned, or in positional agreement, with the receiving area 74). The closed end 116 may be at a middle portion 119 of the main section 110. The fasteners 112 are adapted to connect to the fasteners 108. In this embodiment the fasteners 112 comprise a second part of a hooks and loops fastener, such as VELCRO®. Thus, the guide members 110 can be removably connected to the frame of the working head 101. In use, the guides 106 can help locate an electrical connector (and conductor) in a substantially centered location in the area 74 to prevent the connector from being incorrectly positioned.
