Abstract: For an electrical connector for connecting insulated electrical conductors, preferably an electrical plug and socket connector, with contact elements disposed in chambers of a carrying base with cutting and insulation displacement connections for connection to the conductor, the conductors being introduced into the connector in the axial direction, relative to the contact elements, it is proposed that the conductors be pressed by means of a conductor guiding element, which is constructed as a pressure part, into the cutting and insulation displacement connections. At the same time, the conductors are pushed through a guiding borehole, in which they are deflected in such a manner, that they are guided obliquely through a recess in the conductor guiding element. When the carrying base and the conductor guiding element are joined together, the cutting and insulation displacement connections dip into these recesses and, in so doing, are connected with the conductors.

Abstract: This carrier for a plurality of transistors or other semiconductor devices comprises a unitized body of plastics material having inclined guide surfaces between adjacent guide walls of laterally spaced positioning blocks extending upwardly from a base of the carrier. These guide surfaces and walls guide the leads of the transistors into laterally spaced openings formed through the carrier base which align with openings in a printed circuit board after the carrier is attached to the board by snap-in fasteners. The transistors are seated and held in an upright and aligned position on the carrier by integral leaf-type springs which bias them against the front walls of the blocks for subsequent handling and wave soldering to the board.

Abstract: Disclosed is an improved electrical connector terminal mount which has an engagement piece integrally formed in the terminal base. The engagement piece functions to fix the terminal in an associated terminal slot. The engagement piece is a metal strip cut away from the base of the terminal in the form of flattened "V"-shaped cantilever arm. The metal strip consists of a first section bent outward on one side of the base of the terminal and a second section integrally connected to and extending inward from the end of the first section toward the other side of the base of the terminal ending in a free end. An engagement slot perpendicular to the terminal slot is formed within which the engagement piece fits, thereby enabling the terminal to fixedly lie along the center line of the terminal slot and to prevent the vertical movement of the terminal out of the terminal slot.

Abstract: A sealing system is provided between an electrical connector assembly and another connector component, panel or the like. The connector assembly includes a housing having a mating end with a seal-receiving channel and a resilient seal received in the channel. The seal includes a sealing groove having a given width and a given depth.

The sealing lip has a width greater than the width of the sealing groove and a length relative to the depth of the sealing groove such that the lip is spaced from the bottom of the groove when the connector assembly and the connector component are in mated condition. Therefore, only sealing forces normal to the mating axis are effected between the sealing lip and the sealing groove.

The connector arrangement includes a plug receiving an inner contact spring connected to an inner conductor of a coax cable with the contact spring receiving the signal-carrying contact blade and the braided shielding of the coax cable is connected to the contact blades lying at the shielding potential via a resilient spring collar having outwardly bent spring tongues in one end of the plug.

Abstract: An electrical connector system includes a torsion bar spring for maintaining good contact forces in small sizes, simple configurations and controlled connector insertion forces. The electrical connector system includes a first and a second terminal. The first terminal has two electrical contacts connected by a shaft. The shaft is made of a resiliently deflectable electrically conductive material. The second terminal is a helically-shaped hollow body adapted to receive the first terminal. When the first terminal is inserted in the second terminal, the shaft of the first terminal is deflected and acts as a torsion bar spring and the two contacts lock the torque inside the second terminal. An alternative embodiment includes a first terminal with protrusions and a second terminal with a helical groove on its interior surface which receive the protrusions of the first terminal and cause the first terminal to deflect on insertion into the second terminal.

Abstract: An electrical connector assembly is provided having a first electrical connector and a second electrical connector. The second electrical connector has a housing with a connector receiving area and spring contacts. The first electrical connector has contacts located in the receiving area and contacting the spring contacts with suitable frictional forces and shapes at their areas of contact to provide substantially no resistance, by the contacts, to movement of the first connector out of the receiving area. This is accomplished due to geometric spring action force vector being substantially equal and opposite to the frictional force vector in the direction of movement of the first connector out of the receiving area. However, the frictional forces and spring action forces are additive during insertion of the first connector into the receiving area to thereby wipe the areas of contact between the contacts of the two connectors.

Abstract: In a connector comprising: a terminal having an electrically contacting spring piece which is accommodated in a surrounding wall in such a manner that it is allowed to protrude through an opening formed in the surrounding wall; and a connector housing into which the terminal is inserted, the spring piece has an electrically contacting portion confronted with the opening, and an slide portion bent in such a manner that it is away from the opening, and the connector housing has a depressing protrusion for depressing the slide portion. As the terminal is inserted into the connector housing, the depressing protrusion depresses the slide portion so as to cause the electrically contacting portion to protrude outside through the opening. Thus, the electrically contacting spring piece of the terminal is protectively held in the terminal until the latter is inserted into the connector housing.

The bearing is adapted to be engaged by a lever that is pivotally connected to the frame. The disk drive is secured to the housing by rotating the lever from a first position to a second position, such that the lever latches onto the bearing.
