Claims
- 1. A hand held impact tool for use in terminating electrical conductors at a terminal block, comprising
- an elongate handle,
- a slide assembly mounted in said handle yieldably urged toward a position extending from one end thereof,
- a hammer assembly mounted in said handle operating to deliver a hammer blow to said slide assembly,
- a drive spring seat member mounted in said handle,
- a hammer drive spring extending between said hammer assembly and said drive spring seat member urging said hammer assembly toward said slide assembly,
- a cam follower surface on said seat member,
- a cam bearing against said cam follower surface and mounted in said handle being movable relative thereto,
- movement of said cam operating to alter the compressed length of said hammer drive spring, whereby said hammer blow is greater when the compressed length is lesser,
- a pouch assembly in the other end of said handle,
- said slide and pouch assemblies being configured to accept termination tool blades including means for engaging the electrical conductors, each of said slide and pouch being independent of the other whereby to store one termination blade in said pouch assembly while, at the same time, another termination blade is mounted in said slide assembly for use in terminating the electrical conductors,
- and means in said pouch assembly for releasably retaining either of said termination blades therein,
- said pouch assembly comprising a storage cylinder movable rotationally relative to said handle and having a bore therethrough accepting the termination tool blade, said means for releasably retaining a termination blade comprising a coil spring mounted in said bore having one end thereof movable with said storage cylinder and having a diameter smaller than said storage cylinder bore and operating to engage the termination tool blade, whereby torquing of said storage cylinder in a sense contra to the spring coil direction expands said inside diameter and releases the termination tool blade from said bore.
- 2. An impact termination tool utilizing a termination blade for connecting electrical conductors to electrical terminals, comprising
- a handle,
- a slide mounted in one end of said handle movable with respect thereto and yieldably urged toward an extended position therefrom, said slide including means for accepting the termination blade,
- means mounted in said handle for imparting an impact to said slide when said slide is forced inwardly from said extended position a predetermined distance,
- a pouch in the other end of said handle and including means for accepting the termination blade and releasably retaining it therein,
- so that when one terminal blade is mounted in said slide operating to terminate conductors at the electrical terminals, another terminal blade is stored and retained within said pouch,
- said handle having an opening in the other end,
- said pouch comprising a cylinder movable rotationally in said handle and having a bore therein in communication with said opening, and
- said accepting and retaining means including a coil spring in said bore having one end of the coil movable with said cylinder and having an inside diameter smaller than said bore which is adapted to engage the termination tool, whereby rotation of said cylinder in a direction contra to the direction of spiral of said coil spring expands said inside diameter allowing insertion and removal of the termination blade therefrom.
- 3. An impact termination tool as in claim 2 together with
- means mounted in said handle movable to one of two positions for setting said impact at a high or a low level,
- whereby conductor connections with one termination blade requiring low impact level are made when the means for setting is at one of the two positions with reduced operator effort, and connections with the other termination blade requiring high impact level are accomplished with the means for setting at the other of the two positions.
