  • Patent number: 6786746
    Abstract: A squib connector assembly for energizing a gas producer to make it ignite, the squib connector assembly comprising a first component for supporting a male electrical connector element; a second component for supporting a female electrical connector element engageable with the male electrical connector element; and a short-circuit element selectively switchable between a short-circuit position to electrically short-circuit the male electrical connector element and a non-short-circuit position. A flat-plate-like noise filter having electromagnetic wave absorbing material is arranged between the first component and the short-circuit element, so as to allow the male electrical connector element to extend through it and surround the male electrical connector element. This can provide the squib connector assembly that can adequately meet the demand for miniaturization and space saving.

  • Patent number: 6699059
    Abstract: An electrical connector assembly of the present invention includes a first component for supporting a first electrical connector element; a second component for supporting a second electrical connector element inserted in the first electrical connector element to be fitted therein; a short-circuit element, fitted in the first component, for electrically short-circuit the first electrical connector element; and a locking element engageable with the second component in a locked manner. The locking element is so structured that when the second component is inserted in the first component to be fitted therein, the locking element can make the short-circuit element move back to its non-short-circuit position and also can move to engage with the first component. The engagement of the locking element with the first component allows the first component and the second component to be locked against disconnection.

  • Patent number: 6544060
    Abstract: The present invention aims to prevent forcing of pins when a female connector is obliquely inserted into a shunt. A shunt fits into a cylindrical socket concavely formed in an external face of a housing of an airbag inflator and short-circuits of a pair of contact pins of a squib of the inflator. These pins rise at the center of the socket from the bottom to a point near to the opening. The shunt includes an annular wall having a fitting hole into which the pins enter from the bottom side of the center thereof and into which a female connector fits from the top side, and a short-circuit piece provided on the annular wall, which will contact both of the pins when the shunt is fitted into the socket, and will be pushed to move away from the pins when the female connector is fitted into the fitting hole.

  • Patent number: 6296531
    Abstract: A cavity that crosses chambers and opens in an external wall is formed in a housing proper of a housing. A retainer is slidably fitted into the cavity, and linking parts that link chambers being divided into a front portion and a rear portion by the cavity are formed in the retainer. The linking parts are arranged in such a way that when the terminals are in a regular position in the chambers, the linking parts allow the retainer to shift in the sliding direction and the retainer is secondarily fixed to the terminals by this shift. The retainer is provided to be integral with the housing proper by means of a hinge.

  • Patent number: 6272021
    Abstract: The present invention provides a circuit device which insures highly-reliable electrical connections even when used in environments involving large temperature variations, and which can be easily assembled. Board assembly (10) has a housing (50) which is mounted on an edge (150) of a circuit board (100). Edge (150) includes protruding sections (160) on which a plurality of contact pads (180) are aligned. The housing (50) accommodates the protruding sections (160) inside slots (52), which are formed inside the housing (50). Reinforcing sections (55) are disposed on both sides along the lengths of the slots (52). A connector, which engages with a mating connector, is formed by the protruding sections (160) and the housing (50). Since the edge (150) of the circuit board (100) is maintained in a substantially flat-plate shape even in cases where deformation caused by heat occurs in other portions of the circuit board (100), highly reliable electrical connections with mating connectors can be realized.

  • Patent number: 5558526
    Abstract: A connector with a contact-aligning device which can move in the direction of joining connectors and has locking devices which can move perpendicularly to the direction of the joining the connectors. The contact-aligning device has a contact-aligning plate with a number of through-holes corresponding to the number of male contacts and arms extending from the plate toward the back ends of the male contacts. The contact-aligning device can move from the position that is even with the ips of the male contacts to the position relative to the back ends thereof. The connector housing has side walls which have openings for locking devices which when inserted in the openings can assume a temporary-locked position or a fully-locked position. In the temporary-locked position, slanted surfaces on the arms of the contact-aligning device and on the locking devices engage each other and prevent movement of the contact-aligning device.

  • Patent number: 5501606
    Abstract: A connector 10, 30' has a guide member 70, 60' movably latched in its housing 12, 40'. The guide member 70, 60' is used to guide and align contact portions of male contacts. The guide member 70, 60' has a plate 72 formed with a large number of through-holes 84 to pass the male contacts therethrough. Preferably, the guide member 70 is formed with side plates 78 at both sides of the plate 72 perpendicular thereto. Latching arms 92, 94, 96 are stemmed from the free ends of the side plates 78 and extend in the opposite direction, thereby minimizing the apparent length of the latching arms 92, 94, 96 which engage with respective projections 100, 102, 104 on the inner wall of the connector housing 12.

  • Patent number: 5419714
    Abstract: A bolt-fastened connector featuring an easy securing of the bolt in the housing while making it possible to achieve a compact design with a high density of elements is achieved. The bolt-fastened connector (2) comprises first housing (10) accommodating the bolt (20) and the second housing (40) having multiple contacts. A metal member (80) having several spring blades (82) is embedded in an inner wall (58) of a bolt-insertion opening (54) of the second housing (40). When the tip of the bolt (20) retained in the first housing (10) is inserted in the bolt-insertion opening (54), the spring blades (82) snap into a recess of the bolt (20), thereby securing the bolt (20) and the first housing (10) in the second housing (40).
