Claims
- 1. Arrangement for converting a wire trap connection system for receiving stripped wire end to establish a connection which becomes tighter on any attempt to withdraw said wire, to screw clamp connection in a portable electric tool having a housing and a switch control supported internally of said tool housing and having a wire trap system for connection thereto, said arrangement having a connection adapter module for permanent insertion into said wire trap system internally of said housing to provide screw clamp connections to said switch control for the portable electric tool enabling the tool to be rewired or said switch control replaced by a customer with a standard screwdriver, comprising: an insulator body piggy-backed on said switch control; and a plurality of connector elements carried by said instulator body, said connector elements each comprising an insert including a hollow portion captured within said insulator body for receiving a wire therein and having a screw threaded through the wall of said portion and accessible externally of said insulator body for clamping said wire within said portion, and a thin wire-like projection extending from said portion projecting out of the insulator body to be permanently engaged with said switch control wire trap system.
- 2. Connection adapter module defined in claim 1 wherein the portions are provided with alignment means, such as a flatted or slabbed surface to aid in their assembly with the connector body and the body comprises a housing provided with a plurality of bores provided with flatted portions for mating with said flatted or slabbed surfaces so as to provide alignment therebetween and preclude relative rotation.
- 3. Connection adapter module defined in either of claims 1 or 2 wherein said wire-like projections are provided with conical points to aid in the insertion thereof into the wire trap system.
- 4. Portable electric tool having a housing, a switch control supported internally of said tool housing and having a wire trap system for receiving a stripped wire end to establish a connection which becomes tighter on any attempt to withdraw said wire, and a connection adaptor module for permanent insertion internally of said housing in said wire trap system to provide screw clamp connections to said control enabling the tool to be rewired or said control replaced by a customer with a standard screwdriver, comprising: an insulator body piggy-backed on said switch control; and a plurality of connector elements carried by said insulator body, said connector elements each comprising an insert including a hollow portion captured within said insulator body for receiving a wire therein and having a screw threaded through the wall of said portion and accessible externally of said insulator body for clamping said wire therewithin and a thin wire-like projection extending from said portion and projecting out of the insulator body to be permanently engaged with said switch control wire trap system.
- 5. Tool defined in claim 4 wherein the portions are provided with alignment means, such as a flatted or slabbed surface to aid in their assembly with the connector body and the body comprises a housing provided with a plurality of bores provided with flatted portions for mating with the flatted slabbed surfaces so as to provide alignment therebetween and preclude relative rotation.
- 6. Tool defined in either of claims 4 or 5 wherein said wire-like projections are provided with conical points to aid in the insertion thereof into the wire trap system.
