66 Electronic device terminal connector US10538917 2003-08-22 US07189108B2 2007-03-13 Kouetsu Takaya; Hideki Daijima
In a terminal connection apparatus by which the space between terminals, such as the terminals of two adjacent electromagnetic contactors, is bridged by three-phase terminal connection conductors arranged in the order of the phases or in the order of phase switching to realize a motor reversing operation, load switching, power source switching or the like, the three-phase terminal connection conductors are housed in a box-shaped insulation case for unitization. As a result, the terminal connection conductors are collectively surrounded by the insulation case to protect the insulation. At the same time, the terminal connection conductors are connected to an electrical device in a unitized manner, thus preventing wrong wiring operation when they are connected.

70 Electro-mechanical reversing contactor with a single, common base US522937 2000-03-10 US6140896A 2000-10-31 Daniel P. Heckenkamp
An electro-mechanical reversing contactor is disclosed in which a single common base is molded to receive two contactor powerheads. The common base has a bottom surface and upwardly extending sides, with an upwardly extending center divider, thereby forming two powerhead sockets. Each powerhead socket is capable of receiving a powerhead therein. The common base also has a circuit board pocket to receive a single circuit board to control both contactor powerheads. The center divider has an upwardly extending interlock tower to receive an interlock pawl that is engageable with each of the contactor powerheads. The interlock mechanism mechanically prevents both contactors from being energized at the same time. The common base for two powerheads saves labor and material costs in assembling and installing a reversing contactor.
71 Contactor and controller for a contactor US803902 1997-02-21 US5982259A 1999-11-09 David Godfrey; Andrew Jones; Neil Hedley Morris
A contactor comprises first and second armatures which are urged towards contact-making positions by first and second windings, respectively. Each of the armatures displaces the other armature from its contact-making position when moving towards its own contact-making position. A controller actuates each of the windings before deactuating the other of the windings.

73 Electromagnetic changeover relay US178282 1994-01-10 US5382934A 1995-01-17 Horst Hendel; Josef Kern; Bernhard Kleine-Onnebrink
A relay having two coils which are arranged axially flush on a base body (1), wherein each coil has a winding (23, 33) and a core (14, 15) connected by means of a U-shaped yoke (12). A single armature (13) is supported on a center section of the yoke (12) such that it can be changed over between the inner ends of the two cores (14, 15). In addition, two contact springs (7, 8) are arranged between the two cores, on both sides of the same, parallel to the armature. The contact-making ends of the two contact springs rest on a common center contact element (61) in the quiescent state. Depending on which winding (23 or 33) is energized, a corresponding contact spring (7 or 8 respectively) is lifted off the center, contact element (61) and moved into contact with an outer contact element (51 or 52 respectively). The relay is advantageously suited as a pole-reversal relay for driving DC motors having a changing rotation direction (e.g., as found in motor vehicles).
74 Lock mechanism for a limiting contact maker US437070 1989-11-16 US5012214A 1991-04-30 Andre Faffart
A locking mechanism for a limiting contact maker is divulged comprising two levers which act respectively on two pusher blocks actuating the switches of a change-over contact maker. Each of these levers, articulated about a fixed shaft, comprises a roller applied to the profile of a rotary cam by a spring. This cam may pass from a locked automatic operational position in which it allows the switches to close by maintaining the levers away from the pusher blocks, to a tripped position in which the lever acts on the pusher blocks for holding the switches in the open position.

Thermal protection is provided by a thermal image generator and a thermal protection unit in each contactor operating in tandem via a bidirectional line of communication keeping the thermal images in parallelism by one active contactor "talking" to the inactive contactor, the "listener".
76 Phase controller US775261 1985-09-12 US4647838A 1987-03-03 Ching-Piao Chuang
A phase controller of a type consisting of two magnetic contact units, a phase shifting mechanism for a thermal relay, a biasing circuit, a control circuit and a delay circuit, whereby phase shifting by the phase shifting circuit and three-phase currents, in coordination with the biasing effects due to the biasing circuit, alters the peak voltage of the alternating currents flowing past the phase-setting relay, to convert the state of the contacting points so as to incite the magnetic contacts in the phase conversion unit following a change in phase of the three-phase power source, thus maintaining the output end of the power source at a certain phase in a manner convenient and safe enough by all standards.
77 Electromagnetic contactor for battery powered vehicles US35276773 1973-04-19 US3815060A 1974-06-04 TURNBULL M
A compact contactor for a battery operated lift truck. The contactor may be mounted in either of two positions and has its terminals arranged so it can be easily connected in a reversing circuit for a motor. The contactor includes a novel movable contact support which is molded in situ with a magnet plunger. The movable contact support completely isolates the springs for the movable contacts from the switching areas of the contactor and provides a guide for the movements of the plunger. The support for the stationary contact is arranged to position the terminals of the contactor so the contactor is easy to wire and permit a range of different sized contacts to be mounted on the support and electrically connected by a pair of metal members.
