  • Patent number: 6354884
    Abstract: An RJ-45 modular jack connector includes a housing defining a cavity for receiving an RJ-45 plug connector therein, a terminal insert assembled to the housing, an anti-mismating device assembled in the housing and a shield covering the housing. The anti-mismating device comprises a block part and a spring part secured to the block part. The block part with the spring part is assembled in the housing with the block part partly projecting into the cavity of the housing. When the RJ-45 plug connector is inserted into the modular jack receptacle connector, the RJ-45 plug connector pushes the block part to the side, compressing the spring part and moving the block part out of the way of the RJ-45 plug connector. Thus the RJ-45 plug connector is fully inserted into the cavity of the housing. When an RJ-11 plug connector is mistakenly inserted into the modular jack connector, the smaller RJ-11 plug connector will not move the block part aside and be blocked by the block part from full insertion into the cavity.

  • Patent number: 6350142
    Abstract: A compact ZIF type socket is provided having the durability to withstand numerous movements of the slider. The ZIF type IC socket 1 consists of a base housing assembly 10 that accommodates numerous contacts, and a cover housing assembly 40 that can slide over the base housing assembly 10. The cover housing assembly 40 is caused to move in relative terms by inserting a plate-form tool 99 into tool insertion holes 65 and 85 respectively formed in a metal supporting plate 60 on the side of the base housing assembly 10 and a metal supporting plate 80 on the side of the cover housing assembly 40, and rotating this tool 99. The action points of the tool insertion holes 65 and 85 contacted by the tool 99 are formed as circular-arc-form projections 75, 76, 95 and 96. Accordingly, the force of the tool 99 can be transmitted to the base housing assembly 10 and cover housing assembly 40 without causing indentation or damage, etc.

  • Patent number: 6347967
    Abstract: An electrical connector for a threaded shaft includes first and second connector elements, each defining a respective partial-cylindrical threaded surface, a respective hinge element, and a respective tail. The hinge elements are coupled together at a hinge axis such that the connector elements rotate about the hinge axis to move the threaded surfaces toward and away from one another. The threaded surfaces are oriented to contact and intermesh with opposed sides of a threaded shaft, and a fastener holds the tails together to clamp the threaded shaft between the threaded surfaces. A third connector element cooperates with the first connector element to clamp against and establish electrical contact with a cable.

  • Patent number: 6342684
    Abstract: A device for detecting the movement of an object in order to operate a switch, wherein a top or contact of an angled contact part of a contact spring piece of the device comes into contact with a set position of an object, such as a digital video cassette ( DVC) or other cassette or disk which is being transferred so that various kinds of detecting operations are performed. The contact spring piece of the detecting device is improved in durability by forming a flexible spring part, of a predetermined dimension, between an upright mounting plate part and a U-shaped spring part of the contact spring piece. The contact spring piece is made of a plate spring. The contact spring piece includes the upright mounting plate part, the U-shaped spring part, and the angled contact part such that a long spring span is formed between the upright mounting plate part and the angled contact part. The flexible spring part is made to flex by the load of the contact pressure of the object on the angled spring part.

  • Patent number: 6331117
    Abstract: A rotatable electrical connector has a pair of wiring boards. Each wiring board supports two (or more) concentric conductors that have substantially smooth coplanar surfaces. The coplanar surfaces of the concentric conductors on each wiring board define a contact plane. To provide electrical contact between the two wiring boards, each wiring board is positioned perpendicular to an axis of rotation and is supported so that the respective contact planes of the first and second wiring boards are parallel. A resilient member, such as a spring, urges the wiring boards together to establish electrical contact between the respective surfaces of corresponding conductors on the two wiring boards. The above-described wiring boards are included in a circuit module that also includes a printed circuit board, or other electrical component, sandwiched between a pair of the wiring boards.
