Male contact having contact entangling prevention means

The electrical contact has a contact member that contacts the mating contact T. The contact member has a first resilient contact arm which extends rearward from the lower top wall a connecting section which is bent downward at the rear end of the first resilient contact arm, and a second resilient contact arm which extends forward from the connecting section In cases where the mating contact T tends to be pushed further inward after the insertion of the mating contact T has been completed, the area in the vicinity of the rear end of the first resilient contact arm contacts the upper top wall

Electrical contact

The igniter connector comprises an insulating housing having a bead-receiving cavity open at one end, a partition in a center of a bottom wall of the cavity, a ferrite bead disposed in the bead-receiving cavity, and holes in the bottom wall of the bead-receiving cavity for insertion of pin terminals, the ferrite bead that is inserted in the bead-receiving cavity and secured in the insulating housing with the ferrite bead having a central opening through which the partition is passed when the ferrite bead is inserted in the bead-receiving cavity, a pair of electrical contacts having receptacle sections for electrical connection with the pin terminals are arranged in contact-receiving cavities disposed between the partition and the ferrite bead inserted in the bead-receiving cavity and wire-connecting sections for connection to electrical wires, and a cover member enclosing the bead-receiving cavity of the insulating housing is latched to the housing and has posts coaxially aligning the receptacle sections of the electrical contacts with the holes for the pin terminals. The cover member is equipped with a pressure device that exerts pressure on the ferrite bead holding it down against the bottom of the bead-receiving cavity.

A lever type connector has a lever (60) and a housing body (10) consisting of a main body (20) and a wire cover (40). The lever (60) has a pair of arms (65), and an operating part (66) which connects the arms (65) at one end. When the lever (60) is mounted on the housing body (10), the ribs (43) on the inclined parts (42) of the wire cover (40) engage with the arms (65) and act to spread the arms (65) outward. When the arms in this outward-spread state are moved over the posts (22) so that the arms reach positions directly above the posts (22), the arms undergo elastic recovery inward, and act to move the openings (62) into positions in the vicinity of the posts (22).

Lever type connector

The present invention provides a compact lever-type connector with a large degree of freedom in design, which makes it possible to obtain a low-mating force. A lever 10 which has gears 26, and slides 30 which have racks 40 and cam grooves 36a through 36c and 37a through 37c that engage with cam followers of the mating connectors, are attached to a cap housing 2. The racks 40 are driven by the gears 26 of the lever 10. These racks 40 and the cam grooves 36a through 36c and 37a through 37c are respectively formed on opposite sides of the slides 30.

Lever-type connector

An assembly of electric connectors and plug connectors and cap connectors used therein has guiding ribs providing for a smooth joining of the plug connectors and cap connectors, Ribs 16a, 16b and 16c extending from the bottom wall 14 are provided respectively in cavities 6, 8 and 10 of the cap connector 1. All ribs are of the same configuration and have outside surfaces 26, 28 perpendicular to the bottom wall 14, an outside surface 30 parallel to the bottom wall and a slanted surface 20 forming a roughly P-shaped cross section. In the plug connectors, slots of the same configuration as said ribs are formed, thus providing smooth connection by limiting vertical and horizontal deviations during their joining.

Assembly of plug and cap electric connectors

The present invention is directed to a compact lever-type connector in which a lever can be fixed in specified positions. Lever (50) is installed on a side surface (24) of a housing (18) so that the lever (50) is free to pivot. The lever (50) has a lever main body (56) and an extensible lever (58) which is attached to the lever main body (56) so that the extensible lever (58) can be extended and retracted. Respective grooves (80), (82) and (84) are formed in the lever main body (56) and extensible lever (58). An arcuate rib (90) is formed on the housing (18). Only when the extensible lever (58) is extended are the grooves (80) (82) and (84) aligned so that the rib (90) can be accommodated by these grooves, thus allowing pivoting of the lever (50). In the initial and final positions of the lever (50), the extensible lever (58) can be extended and retracting relative to the lever main body (56).

A plastic double-lock member (40) with guide grooves (44) extending in a mating direction for guiding ribs in a matable connector. Integral end walls (48) are formed to close inner walls of the guide grooves (44) at end portions of the guide grooves (44). The end walls (48) are formed with latching lances (50) to engage with an insulating housing (20). The provision of the end walls (48) minimizes the non-uniformity of cooling of the plastic material which comprises the double-lock member (40), thereby reducing undesirable deformation of the double-lock member (40) caused during contraction of the plastic material after molding.

An electrical contact 1 is disclosed which eliminates the possibility of harmful deformations in a bent section of a resilient contacting strip 5 which is bent back from the front portion of a base section 2 of a female contact, even if it experiences a direct impact from a foreign object. Cut-outs 8 are made in the left and fight side walls 3 rising from the sides of the base section 2 of the female contact 1. On the left and right sides of the resilient contacting strip 5, in the vicinity of the bent section 53, protrusions 9 are made which face the left and right side walls 3. The spacing between the cut-outs 8 and protrusions 9 is selected in such a way that they make possible the movement of the resilient contacting strip 5 within allowed limits, but prevent any movement of the protrusions 9 beyond the permitted distance and direction when a foreign object makes a direct impact to the bent section 53.

Female electrical contact with stop for resilient contact

An electrical connector with electronic noise filtering structure is disclosed. Two slits (42) are formed in metal plate (40), which plate is secured on the rear of the electrical connector with through condenser (2). Slits (42) are formed to be at right angles to the longitudinal direction of the metal plate. The width of slits (42) expands or contracts in response to the housing's expansion or contraction due to temperature, and metal plate (40) adapts and prevents stress from accumulating in the through condenser solder section.

Electrical connector with through condenser

A filter connector (40) for filtering unwanted signals from contacts (46) includes a housing (50) having therewith a subassembly (62) including an auxiliary plate (44) holding capacitors (43) in a spaced array, a grounding plate (42) having holes (41) on the spaced array to receive the capacitors inserted therewithin extending into recesses (49) of a ferrite plate (42) with the ferrite plate contiguous with the grounding plate. Contacts (46) are carried by the subassembly with contact ends (46a) projecting forwardly in the housing and post ends (46b) inserted into a PC board (60). The ground plate (42) includes terminals (54-56) projecting to connect the ground plate to ground circuits of the printed circuit board, suitably bent to provide support for the connector prior to soldering. Embodiments include a molded housing, in one form insert molded (50) around subassembly (62) or premolded (71) with the subassembly (62) secured therein.
