  • Patent number: 5490795
    Abstract: An aligning socket for an IC that provides an aligning bar that aligns and secures IC leads to the corresponding socket contacts (6), and where the bar has extensions or ears (42) that extend toward the row of IC leads (38). The ears have chamfered edges that, as the bar is forced toward the IC leads, guide the IC leads to mate with the socket contacts. For more fragile gull-winged leads, a rail 18 is provided to support the under side of the leads and the alignment bar ears are designed to fit over the ends of the rail. When the bar and socket contacts are forced toward the IC leads, the bar ears overlap the ends of the rail and force any mis-aligned IC leads to move such that alignment of the leads and the socket contacts is achieved.

  • Patent number: 5490798
    Abstract: A connector examining device in which a retainer for attaching a terminal within a housing can be pushed into the housing simultaneous with an examination of a connector. When a lever is pulled up, a cam comes in contact with a trailing end surface of a detector portion. This allows the detector portion to slide toward a connector receiving portion. After the detector portion is in contact with the connector receiving portion, the connector receiving portion and the detector portion together are further displaced. At this time, a retainer pusher, fixed to a base, pushes into the housing the retainer temporarily engaged with the housing of the connector held by the connector receiving portion. Thus, the retainer and the terminal within the housing are engaged with one another, and the terminals are engaged with the housing.

  • Patent number: 5490786
    Abstract: A connector has upper and lower rows of contacts (20, 22, FIG. 4 ) whose contact tails (40, 42) are soldered to front and rear rows of pads (26, 24) on a circuit board (14), which provides flexibility in downward deflection of all contact tails in a short forward-rearward distance (B) . While the upper tails of the upper row of contacts extend at a downward-forward incline, the lower tails have rear portions (80) with inclined parts (90) that extend at an upward-forward incline, and forward portions (82) with inclined parts (92) that extend at downward-forward inclines. A heating bar (102, FIG. 7 ) for heating the forward ends (120, 122) of the contact tails for reflow soldering to the pads, has slots (124) in its lower surface (106) that extend from its rear end (126) to a location (130) behind its front end (132).

  • Patent number: 5489216
    Abstract: This invention prevents lowering of working efficiency and an abnormal deformation, a breakage and the like of conductive terminals upon coupling a printed circuit base plate to a card edge connector in a card edge connector assembly. When a card edge connector 10 is inserted into an mouth 4 in a base plate holder 1, sliding edge portions 27 ride on ramp faces 5a on ribs 5 to pivot a pair of inner housings 20. Then, contacting portions 22a of first terminals 22 engage with second terminals on opposite sides of a printed circuit base plate 2. The printed circuit base plate 2 enters smoothly between the contacting portions 22a without causing an elastic deformation in the portions 22a and gouging the plate 22 due to their contact.

  • Patent number: 5484298
    Abstract: Disclosed is an improved XLR connector which automatically terminates at least two of the matable connecting terminals of the XLR connector when the XLR connector is not attached to another XLR connector. The XLR connector includes a spring-biased switching member which opens and closes depending on whether the XLR connector is attached to another XLR connector. According to a first embodiment of the invention, an internal resistor is provided in the XLR connector which has a resistance that matches the impedance of the signal lines coupled to the XLR connector. According to a second embodiment, two additional terminals are provided on the XLR connector which are coupled together through the switching member. Thus, the state of the XLR connector may be detected by detecting the potential difference between the two additional terminals.
