Abstract: A tool (34, 144) is provided for extracting a contact (16, 112) from the front end of a connector, which not only has a sleeve (70) to release a locking clip (30) that holds the contact in position, but that also has a highly resilient grasping clip (80) that grasps the contact to pull it out when the tool is withdrawn from the connector. In a tool for a connector which has a barrel (29) lying within the locking clip and that has a smaller diameter location (32) forward of the barrel, the grasping clip (80) with spring fingers (86) lies in the sleeve at a position wherein the spring fingers can grasp the smaller diameter location of the contact to pull out the contact.

Abstract: The present invention relates to a snap arrangement comprising snap hooks (208) associated with a first housing (200) that snap over corresponding protrusions (111) in a second housing (100). The snap hooks preferably include an inclined portion (212) such that a finger (504) of a certain width of a removal tool (502) will force them apart to the deflection required for disassembly. Once the tool has been inserted beyond the elbow (213), the snap hook is not deflected any further regardless of the motion of the tool. This enables the tool to continue moving the front housing apart from the rear housing without further deflecting the snap hooks. This ensures that the snap hooks are never overstressed, that the front housing comes completely off of the rear housing every time, and that repeated disassembly will only minimally affect the strength of the snaps.

Abstract: A maintenance device for the servicing of overhead modular photoelectric control switches, from ground level. This invention integrates the means to functionally test, remove, and install photoelectric control switch modules, normally associated with outdoor lighting. Alternatively, the device can remove and install high intensity light bulbs. The device comprises a pair of rotatable contracting grips, at one end. The grips respond to rotation of a cam, which also attaches the opposite end of the grips to a flex-head ratchet wrench. The wrench selectively imparts either clockwise or counterclockwise drive to the cam and, therefore, the grips. The opposite, or handle, end of the ratchet wrench is in sequence connected, via a universal attaching head, to a telescopic pole. When the grips are slided over a modular photoelectric control switch, the amount light striking its sensor is reduced, causing a functional module to switch on. If it fails to switch on, the module has malfunctioned and must be replaced.

Abstract: An electrical connector is made repairable by providing a front insert which is removable from and retained in the shell by an O-ring. The shell includes an undercut in which the O-ring is mounted, and the insert includes a circumferential elliptical groove. In use, as the insert assembly is inserted into the shell, the O-ring mounted on the undercut of the shell is compressed by the insert until it reaches the groove, whereupon it expands into the groove in a direction parallel to the direction of insertion, which constitutes the major axis of the elliptical profile of the groove, and thus provides positive retention and sealing without the need for additional retention mechanisms. Removal is facilitated by a removal tool which includes hooks extending from a front circumference of a sleeve of the removal tool. The hooks are inserted through slots in the insert and past a collar provided around the mating interface of the insert.

The even action of the teeth disengages the chip from the socket without bending pins of the chip or otherwise damaging the chip. Further, the tool does not rest upon or press against the circuit board as the chip is removed from the socket, so the tool removes the chip from the socket without damaging other components on the circuit board.

Abstract: Male and female portions of a multi-pin connector (MPC) are separated and connected using a tool or a method in which the two MPC portions are securely retained in lateral and longitudinal alignment throughout separation and connection, to alleviate the difficulties of breaking, bending, mis-aligning and twisting pins of the male MPC portion relative to sockets of the female MPC portion, which may easily occur during separation and connection. The pins and the sockets in lateral and longitudinal alignment while the MPC portions are moved toward and away from one another. The risk of lead-wire breakage due to fatigue from grasping the lead wires during connection and separation is also avoided, because the only contact is with the body portions, not the lead wires, of even small MPCs. A tool includes a receptacle adapted for receiving the two portions of the MPC.

Abstract: A tool for removal and insertion of a backplane or other electrical member with respect to a housing comprises a frame which can be fixed with respect to the housing and a carriage which can be connected to the electrical member. The carriage is guided in floating relation with respect to the frame and is movable in a first direction to remove the electrical member and in a second direction to insert the electrical member. Fixing the frame with respect to the housing prevents movement of the frame away from the housing, thereby enabling application of force to the carriage sufficient to overcome resistance to insertion of the electrical member.

Abstract: A driving slope of a disengaging member of a terminal removing jig is pushed into a gap between an electric contact portion of a metal terminal and a disengaging free end part of a cantilever-like flexible engagement portion of a connector housing so that the engagement part of the flexible engagement portion is pushed up. The jig is then pushed inward further so that a butting surface of a pushing member of the jig is put into contact with the front end of the electric contact portion of the terminal to move it back out of the connector housing. Therefore, it is possible to dispense with pulling out a metal terminal from a connector housing with a hand, to make it easier to remove the terminal from the housing out of it.
