A pressure welding apparatus includes a pressing die assembly 50 which has a plurality of stuffers 54 that pressure-weld electric wires 45 to the pressure-welding parts 34 of contacts 30, and a comb 70. The pressing die assembly 50 has a plurality of pins 60 which are located adjacent to the respective stuffers 54 and which are constantly driven downward by springs 62 so that the pins 60 protrude beyond the lower ends of the stuffers 54. The widths of the respective pins 60 are set so that these widths are substantially equal to the widths of the cavities 16 of the housing 10 in which the contacts 30 are accommodated. As a result, the pins 60 advance into the housing cavities 16 located adjacent to the contact 30 on which pressure-welding is to be performed, and support the housing partition walls 20 from the sides during the pressure welding process.

The plug housing (40) is placed inside the cover housing (10), and they are joined together by means of the lever (2) . Holes (8) of the lever (2) are placed over mounting projections (18), and the lugs (5) of the lever (2) are engaged with the lug engaging members (50) of the plug housing (40) through the opening (16). The lugs (86) of the cap housing (80) are latched in the slots (22) of the cover housing (10), thus joining these housings together. By operating the lever (2), the plug housing (40) is moved inside the cap housing (80) making electric connection with the contacts of the cap housing (80).

An electrical connector (10) for electrical connection to a complementary electrical connector (20) comprises a housing (10a) having electrical contacts (13) secured in passageways (11) by housing lances (14); a movable contact guide member (40) is positioned in the housing (10a) and includes a guide plate (41) having holes (43) through which ends of contact sections (132) of contacts (13) extend when the contact guide member is an outer position so that holes (43) serve to align and guide the contact sections (132) for electrical engagement with complementary contact sections (231) of electrical contacts (23) secured in housing (20a) when contact guide member (40) moves to an inner position during the engagement between connectors (10, 20); and the movable contact guide member has an inner section (42) that extends along and maintains the housing lances (14) in latching engagement with the contacts (13).

A system is provided for carrying out a reference point return in a numerical control device. A deceleration dog (31) is arranged at a machine table (1) and includes a reference point (4). A deceleration limit switch (2) is operated when in contact with the deceleration dog (31), to generate a first deceleration signal (DEC1). A portion of the deceleration dog (31) from an end thereof with which the deceleration limit switch (2) first comes into contact to a predetermined distance therefrom is used as a hypothetical dog. A deceleration signal generating means generates a second deceleration signal (DEC1) when the deceleration limit switch (2) is in contact with the hypothetical dog. A reference point return processing means carries out a reference point return based on the first and second deceleration signals (DEC1, DEC2). Accordingly, an adjustment of the deceleration dog becomes unnecessary, and the assembling and maintenance are made easy.

A receptacle terminal has a receptacle portion including leaf spring means at a forward end of the receptacle portion that are inclined toward an upper wall and auxiliary spring means spaced rearwardly from the forward leaf spring means. Upon insertion of a tab portion of a male terminal into the receptacle portion the leaf spring means can engage the auxiliary leaf spring means or the bottom wall and the auxiliary leaf spring means can engage the bottom wall thereby preventing the leaf springs from deformation. Accordingly, a permanent set of the leaf springs cannot occur enabling the spring forces to remain constant which ensures optimal contact pressure on the tab portion realizing an effective electrical connection.

An operation history display device of a numerical control apparatus by which a fault causing factor can be easily specified. Key input means outputs the key signal of an operation key depressed by an operator to input a command to the numerical control apparatus. Change detection means detects a change of an output signal and outputs the signal to which the change is caused. Operation history control means stores the signal name and the like of the signal to which the change is caused to a history buffer together with a present time output from a timer as history data. Thereafter, display control means displays the history data stored in the history buffer on a display unit in response to a predetermined operation performed by the operator.

A connector (C1) includes a housing (10) and a pair of terminals (T1) adapted to interconnect to a pair of wires (W1, W2) to electrically connect with terminals (33, 35) of a connector (R1); wherein the connector has a key (20) that is movably latchable in the housing in one of two positions in accordance with the orientation of the wires as terminated to terminals (T1) to form an appropriate connector orientation relative to a keyway and the mating connector and assure proper mating of connectors and wires, despite random orientation of wires as terminated.
摘要:
A laser machining control method using a numerical control system for controlling an X-Y table. A command program (2) in a memory is read out for each one block to cause a lamp on an operation panel (5) to be lit. An operator changes, sets and inputs an output power (S), a frequency (P) and a pulse duty (Q) depending on required conditions. The input conditions are applied to a high-frequency power source (6), and laser machining is carried out under these conditions.
摘要:
A laser oscillation control system performing laser beam machining by controlling an X-Y table by a numerical control system.An output of a laser oscillator is controlled by a G-code included in a program from a command system input to a numerical control system. An output power is commanded by an address S, a frequency by an address P and a pulse duty by an address Q. These command data are fed to a high-frequency power source to control a laser output.
