  • Patent number: 9653848
    Abstract: A connector includes a housing and a plurality of signal contacts and a plurality of ground contacts. Each contact includes a contact portion that contacts an object, a connection portion mounted on a substrate, and a fixing portion located between the contact portion and the connection portion in the vicinity of the connection portion. The signal contact and the ground contact are aligned and held in the housing, and the fixing portion is fixed to the housing. When the plurality of signal contacts are arranged between the ground contacts, at least two of the ground contacts are coupled and connected integrally or by a separate component, the coupling and connection being made in a section of each ground contact between one end (leading end) of the contact portion and the fixing portion, so that high-frequency transmission characteristics are improved.

  • Patent number: 7758355
    Abstract: In the case that a distance between contact portions and fixed portions of contacts of a connector is 2 mm or more, the contacts are each provided with an engaging portion in the proximity of the fixed portion, and the housing is provided in the inserting holes for the contacts with anchoring portions at locations corresponding to the engaging portions of the contacts so that the engaging portions of the contacts engage the anchoring portions of the housing, thereby preventing the contact portions of the contacts from being deformed and collapsed into a fitting opening by a connecting object, and preventing the contacts from buckling or being damaged and hence preventing any defective electrical connection.

  • Patent number: 7241167
    Abstract: A connector includes a housing and a required number of pusher members. The housing has a fitting aperture into which two or at least three flexible printed circuit boards are inserted and insertion openings for holding the required number of the pusher members. When the two or at least three flexible printed circuit boards are inserted into the fitting aperture of the housing, contact portions of the two or at least three flexible printed circuit boards are urged by the pusher members so as to be connected to each other to achieve electrical continuity of the connector. With this construction, the connector can be mounted on anywhere with the exception of a flexible printed circuit board as by adhesion or pushing down by a frame of the set without using soldering, thereby permitting low cost manufacture and wide freedom of selection of connector mechanisms.

  • Patent number: 7238054
    Abstract: A connector includes a plurality of contacts each having at one end a contact portion adapted to contact a connecting object, at the other end a connection portion to be connected to a substrate or the like, and between the contact and connection portions a fixed portion to be arranged and held in a housing so that the contact portion is displaceable about the fixed portion as a fulcrum in a cantilevered manner relative to the housing arranging and holding the contacts. If the thickness of the housing where the contact portions of the contacts are displaceable is not more than 0.6 to 0.7 mm, the housing is provided with a protrusion formed with a hole to permit the contact portions to be displaceable in the hole, thereby ensuring sufficient contact pressures to obtain stable connection with a mating connector without unintended deformations of the contacts.

  • Publication number: 20060128213
    Abstract: A connector includes a plurality of contacts, an insulator for arranging and holding the contacts, and a nut for securing the connector to a substrate or panel. The insulator is provided at a predetermined position with a flange which is formed with an inserting portion for accommodating the nut, and at the inserting portion at least two elastic pieces are arranged which are elastically deformable and adapted to engage the nut. The nut holding structure thus constructed for the connector is able to securely hold the nut with the simple construction without any fracture of the insulator.

  • Patent number: 7059906
    Abstract: An electrical connector includes a plurality of contacts 16, a housing 12 for holding and fixing the contacts 16 therein and having a fitting portion 24 with which a mating object is fitted, and two shells 20 and 22 covering the housing 12. One shell 20 of the two shells comprises at a predetermined position with respect to its longitudinal direction a required number of substantially L-shaped engagement portion 23 integrally formed on the one shell 20. With this construction, even with an electrical connector of miniaturization of height of less than 2 mm, it is possible to provide a connector 10 whose shells 20 and 22 are prevented from being deformed due to undue forces accidentally acting upon the coaxial cables 14.
