A multiple piece terminal includes a first section which is stationary relative to the housing of the connector and rotatable sections which are rotatable relative to the first section. Each of the sections is comprised of a single thickness of metallic material wrapped into a substantially cylinderical configuration, where the rotatable sections are of a larger outer diameter than the first section such that the rotatable sections can engagingly overlie the first section. The first section is mounted to an insulative housing with a post section upstanding through the center of the first section. The post has at least one through opening which includes at least partially along its length, a frusto-conical section for wire section through the opening. The rotatable sections of the terminal has two wire receiving openings, each in communication with a wire-receiving slot around the circumference of the cylinder, with the two wire receiving openings being on opposed sides of the through opening on the post. Caps fit over the rotatable sections of the terminal, each cap has a shoulder which is engagable with a free end of a respective rotatable section of the terminal for rotation of the rotatable section of the terminal relative to the first section of the terminal. When wires are placed in through the caps and the caps are turned, the rotatable sections of the terminal are rotated and the wires are terminated in the wire-receiving slots.

Insulation displacing barrel terminal

An electrical terminal includes a barrel terminal having an L-shaped slot which includes a vertical portion which extends to the upper edge of the terminal, the vertical portion being in transition with a horizontal portion extending partially around the terminal. A cap which is profiled for receipt over the terminal includes an opening which is disposed diagonally through the cap relative the length of the cap. The cap also includes a window which exposes the opening from the end face of the cap for viewing the location of the opening and for viewing the insertion of the wire into the opening. Upon insertion of the wire into the cap, placing the wire in the opening and placing a tool over the cap which pushes the wire into the vertical slot, rotation of the cap and tool moves the wire into the horizontal portion of the L-shaped slot and terminates the end of the wire in a wire receiving slot. Strain relief members are disposed above the opening in the face of the cap and comprises downwardly directed fingers which capture the wire upon termination of the wire.

A barrel-shaped terminal has two spiralled walls forming a cylinder of double thickness material. The terminal has two wire receiving openings, each in communication with a wire-receiving slot around the circumference of the cylinder. A cap fits over the terminal and has a central opening aligned with both wire-receiving openings. When a wire is placed in through the cap and the cap turned, the wire is terminated in a wire-receiving slot.

A barrel-shaped terminal has two spiraled walls forming a cylinder of double thickness material. The terminal has a wire receiving opening in communication with a wire-receiving slot running around the circumference of the cylinder. Placing a wire in a wire receiving opening and rotating the wire with respect to the axis of the cylinder, terminates the conductor of the wire in the wire receiving slot.

A miniature switching device, intended for mounting on a circuit board, is disclosed comprising a housing, having at least one switch cavity therein. Each switch cavity has therein an actuator and a spring contact member. When the switch is mounted on a circuit board, the spring contacts are directly engageable with fixed contact points on a circuit board. The switch has multiple, as well as single, function capability.

Stamped and formed sheet metal terminal device has improved mounting means for mounting terminal on a circuit board. Mounting means comprises first and second coextensive mounting legs extending from the terminal and having free ends which are remote from the terminal. The legs have retaining portions adjacent to the terminal and reduced width portions extending from the retaining portions to the free ends. Camming means are provided on the reduced width portions which cause the retaining portions to move apart during final stages of movement of the legs into the circuit board hole and thereby establish an interference fit of the legs in the circuit board hole.

A resilient platelike spring contact member is disclosed of the type which is mounted on a circuit board in covering relationship to a first conductor and in electrical contact with a second conductor so that the platelike member can be flexed into engagement with the first conductor to establish a circuit path to the second conductor. The platelike member has a pair of legs extending therefrom which extend into holes in the circuit board and each leg has a laterally extending spring contact portion which bears against a second conductor on the circuit board. The legs are shaped such that when the contact member is assembled to the board, the legs are deformed and the contact member is secured on the board without solder or other bonding material.

Solderless circuit board contact

Multi-contact electrical connector comprises a housing having a plurality of side-by-side cavities extending therethrough. Each cavity has a terminal therein which has a wire-in-slot connecting means intermediate its ends and a crimpable portion, adjacent to the rearward end of the cavity, which can be crimped onto a wire. The wire-receiving means and the crimpable means are arranged such that a wire can be inserted into the wire-receiving slot and the crimpable portion can be crimped onto the wire in a single stroke of an inserting and crimping tool.

A continuous strip of bundle tie material comprises a flat strip of thermoplastic having a generally channel shaped cross section. The upper surfaces of the sidewalls are provided with relatively fine ratchet teeth and the web of the strip has openings therein at regularly spaced intervals. In use, a section of the strip is passed around a bundle and one end is folded along the axis of the strip so that the fine ratchet teeth are directed outwardly and in opposite directions. The leading end is passed through an opening which is adjacent to the trailing end. The web material which is between the openings at the leading end forms coarse ratchet teeth for cooperation with the opening and the fine ratchet teeth cooperate with the opposed side edges of the opening. The fine ratchet teeth provide a fine or delicate adjustment so that the tie can be tightened on the bundle to the precise degree desired. The coarse ratchet teeth provide a safety feature to prevent removal of the tie from the bundle if the tie is subjected to extraordinary load conditions.

Bundle tie devices and material

A connector system for connecting together selectable pairs of terminal posts from two matrices of pairs of terminal posts mounted upon a common substrate and in which the columns and rows are interleaved. A first type connector housing configuration is employed to connect together a given pair of posts from a given row in a first matrix to a second adjacent pair of posts in the adjacent row of the second matrix. A second type connector having a second configuration is employed to connect a first pair of posts, such as said given pair of posts, to a third pair of posts which are adjacent said second pair of posts in said adjacent row of said second matrix. The configurations of the housing envelope of said first and second type connectors are constructed to fit together, side-by-side, in whatever arrangement they are placed on the post matrices to be able to cover substantially the entire surface of said substrate, thereby obtaining the maximum size and strength for said connector housings for the densely populated matrices of terminal posts.
