Tool for stripping electric cables

1. Tool ( 1 ) for stripping electric cables, the tool being of the type comprising:

a body ( 2 );

a cable support head ( 4 ) connected to the body ( 2 ); and

a knife holder ( 7 ) supporting a cable sheath incision knife ( 8 ), the cutting portion ( 9 ) of the knife ( 8 ) being capable of extending beyond the knife holder ( 7 ), the knife holder ( 7 ) being configured to receive a socket ( 34 ) supporting the incision knife ( 8 ), and a clip ( 36 ) arranged so as to be movable inside the socket ( 34 ), the clip ( 36 ) being provided with a locking/unlocking opening ( 136 ) intended to interact with a groove ( 102 ) arranged on the shaft ( 100 ) of the knife ( 8 ).

2. Tool according to claim 1 , wherein the groove ( 102 ) is arranged at the end ( 101 ) of the knife ( 8 ) opposite the cutting portion ( 9 ).

3. Tool according to claim 1 , wherein the knife holder ( 7 ) receives the socket ( 34 ) in a sliding manner to adjust the projection height of the knife ( 8 ) from the knife holder ( 7 ).

4. Tool according to claim 3 , wherein the knife holder ( 7 ) receives a knob ( 38 ) such that said knob can rotate relative to the knife holder ( 7 ), which knob is provided with an internal tapping ( 39 ) which acts on an external thread ( 35 ) of the socket ( 34 ) in order to displace it in a sliding manner.

5. Tool according to claim 1 , wherein the knife holder ( 7 ) defines passages ( 150 a , 150 b ) which are adapted to provide access to the clip ( 36 ) from outside the knife holder ( 7 ).

6. Tool according to claim 1 , wherein the body ( 2 ) extends along a longitudinal axis X-X and further defines a recess ( 3 ) delimiting a cable support head ( 4 ), the knife holder ( 7 ) being received in a sliding manner in relation to the body ( 2 ) substantially along the longitudinal axis X-X and including a free end ( 60 ) arranged in the recess ( 3 ), facing the support head ( 4 ), beyond which end the cutting portion ( 9 ) of the knife ( 8 ) extends; the tool ( 1 ) further comprising:

a biasing means which acts on the knife holder to displace it towards the support head; and

a gripping means ( 32 ) which is rigidly connected to the knife holder ( 7 ) for maneuvering it,

the knife holder ( 7 ) being movable between an advanced position in which the incision knife ( 8 ) is moved closer to the support head ( 4 ) under the action of the biasing means ( 32 ) and a retracted position in which the incision knife ( 8 ) is moved away from the support head ( 4 ) against the action of the biasing means ( 32 ),

the gripping means ( 22 ) being arranged adjacent to the free end ( 60 ) of the knife holder ( 7 ) and comprising a bearing face ( 62 ) adapted to receive a cable to be engaged in the support head ( 4 ).

7. Tool according to claim 6 , wherein the bearing face ( 62 ) is oriented in relation to the longitudinal axis X-X such that a force F applied to the cable in a direction substantially transverse to the sliding direction of the knife holder ( 7 ) acts on the knife holder ( 7 ) with an axial force component F 1 x capable of displacing the knife holder ( 7 ) from its advanced position towards its retracted position against the action R of the biasing means ( 32 ).

8. Tool according to claim 6 , wherein the gripping means ( 22 ) is arranged so as to project laterally, at least in part, from the support head ( 4 ), and in that the bearing face ( 62 ) is inclined in relation to the longitudinal axis X-X of the body ( 2 ), laterally from the end ( 60 ) of the knife holder ( 7 ) towards the end of the body ( 2 ) opposite the head ( 4 ), moving away from the longitudinal axis X-X, the inclination being between 45° and 90°.

9. Tool according to claim 1 , wherein it further comprises a retractable cutting blade ( 40 ), pivotally articulated to the body ( 2 ) at the opposite end from the support head ( 4 ), the blade ( 40 ) being movable between a rest position in which it is closed, retracted inside the body ( 2 ), and a working position in which it is open, completely extended from the body ( 2 ), and in that the body ( 2 ) further comprises a channel ( 150 ) which is transverse in relation to the axis X-X and intended to receive an electrical conductor, the cutting portion ( 152 ) of the blade ( 40 ) interfering in the profile of the channel ( 150 ) in order to strip the conductor when the blade ( 40 ) is in a virtually closed position.

10. Tool according to claim 9 , wherein an opening member ( 44 ) locks the blade ( 40 ) in a completely open position, extracted from the body ( 2 ).
