Abstract: The present invention relates to an insulation stripping device for the partial removal of a cable insulation, comprising at least one electrically conductive blade (100) for cutting through the cable insulation, and to an adjustment means for use with an insulation stripping device of this type. The present invention further relates to a method for finishing cables and to an adjustment method for adjusting a blade (100) position in an insulation stripping device. According to the present invention, the insulation stripping device comprises a capacitive sensor unit, which is connected to the conductive blade (100) and is formed in such a way as to emit an output signal if the conductive blade (100) contacts a electrical conductor (104) of the cable.

Abstract: The quality of a crimped connection produced by the application of a crimping force (F) to a crimping barrel (WB) of an electrical terminal (T) with a wire (W) therein, is carried out by measuring the peak value (PV) of the crimping force (F) and comparing it with a reference value. The incremental values (IV) of the crimping force are measured during its application and are stored in the form of an actual crimping force value envelope (EA). The incremental values of an ideal crimping force are measured during its application and are stored in the form of an ideal crimping force value envelope (EI). The envelopes (EA and EI) are then compared to determine the quality of the crimped connection.

Abstract: The press (2) comprises a housing (4) in the forward part of which a slide ram (22) is mounted on bearings (62). The ram (22) is driven by an electric motor (26) by way of reduction gear box (24), having an output shaft (79) to which is eccentrically mounted a stub shaft (78) surrounded by a roller bearing ring (80) in a bearing block roller (82). As the output shaft (79) is rotated by the motor (26), the roller (82) rolls back and forth along a guideway (74) formed in the rear face of the ram (22), to take up the eccentricity of the shaft (78). The ram (22) is centrally mounted in its bearings (62) to avoid its canting as it is driven.

Abstract: A press (2) having a three phase, brushless, direct current drive motor (26) driving a press ram (22) by a way of an eccentric shaft (78) is provided with a control circuit arrangement (89) comprising an incremental encoder (30) for measuring the angular position of the drive shaft (78), and Hall effect sensors (94) for continuously measuring the speed of the drive motor (26). The control circuit arrangement (89) also comprises a computer (108) having registered therein a desired motor speed program (112), and a motor control circuit (104) for comparing the outputs of the encoder (30) and the sensors (94) with the program (112) and feeding the result of the comparison to a motor drive pulse generator (96) to control the speed of the motor (26) in accordance with the program (112) and to stop motor (26) upon the press ram (22) reaching a position at least proximate to its home position (0.degree.) at the end of a cycle thereof.

Abstract: The apparatus comprises wire gripper jaws (2, 4), a crimping die (6), a crimping anvil (7) and an insulation stripping unit (8). An insulated wire (W) is inserted between the jaws (2, 4) in an open position, between the die (6) and the anvil (7) and between stripping blades (14) of the stripping unit (8), to engage a wire sensor (26). The jaws (2, 4) then close, the stripper blades (14) close to sever the insulation of the wire (W) and the stripper unit (8) is retracted to strip the end portion (P) of the wire (W). The die (6), and the anvil (7) onto which a terminal (T) has been fed are then simultaneously moved towards each other to crimp the terminal (T) to the stripped wire end portion (P) and the jaws (2, 4) are opened and the die (6) and anvil (7) are moved apart. The wire (W) is then ejected from the jaws (2, 4) by an ejector (28).

Abstract: The installation comprises a press (2) having a press ram (22) which is driven by a drive electric motor (26), to drive an applicator ram (47) of an electrical terminal applicator (44). A control circuit arrangement (89) controls the drive motor (26) so that the press ram (22) is brought at least substantially to its top-dead-center, home position after each press cycle and also has sensors (140 and 142) for sensing the absence of a terminal (T) from a strip (S) and of terminals (T) fed to the applicator (44), to cause the press ram (22) to carry out an extra cycle to place the next following terminal (T) on the anvil (58) of the applicator (44). The control circuit arrangement (89) controls a lead making machine (114) which includes the applicator (44); and performs various other control functions.
