  • Patent number: 10734766
    Abstract: For example, a cable connector including rising portions for cable connection is provided in which transmission characteristics are excellent and connection work can be easily conducted. Two pairs of signal terminals (11B-11E) and a ground terminal (11A) placed between the pairs of signal terminals are included. These terminals (11A-11E) include rising portions (11Ab-11Eb) exposed from a terminal support member, the rising portions rising from a principal surface, which has a terminal-to-terminal direction and a length direction, of the terminal support member toward a cable connection side in a height direction.

  • Patent number: 10707625
    Abstract: In a typical connector, multiple terminals are not arranged at regular intervals on the same plane. Thus, impedance matching for transferring a high-frequency electric signal cannot be established, leading to problems such as lowering of high-frequency characteristics. For solving these problems, a connector is provided. The connector is a substrate-side connector including multiple terminals arranged in parallel on the same plane and bent at bent portions, an insulator configured to hold the multiple terminals, and an outer conductor shell configured to house the insulator. The substrate-side connector is configured such that a change in a terminal interval at each bent portion of the multiple terminals is reduced, and therefore, influence on the high-frequency characteristics (e.g., a return loss) due to impedance matching disturbance can be reduced.

  • Patent number: 10522950
    Abstract: It is intended to enhance elastic force of an arm and reduce a plate material necessary for forming the arm to effectively use a resource. Provided is a connector fittable to a partner connector, the connector including an insulating housing, a contact, and a conductive shell. The shell includes at least a metal shell formed from a single metal plate. The metal shell includes a cover portion configured to cover at least part of a side portion outer peripheral surface of the housing, an elastic arm having a free end on the side of fitting to the partner connector, and a support portion coupled to a lateral side of the elastic arm to elastically connect the cover portion and the elastic arm and configured to support the elastic arm in a cantilever manner. The cover portion and the elastic arm have substantially opposing surfaces. The elastic arm has a lock portion configured to lock fitting between the connector and the partner connector at a position closer to a free end side than the support portion.

  • Patent number: 10505288
    Abstract: An electrical connector in a type of connectors that comes into contact with a counterpart connector in a gap between contacts of terminals is provided in which the adjustment of contact positions of the terminals is easy and therefore the manufacture of the electrical connector is easy and the manufacturing cost is low. The electrical connector includes a housing and paired terminal supports. Each of the paired terminal supports can support the terminals in cantilever fashion. Moreover, the paired terminal supports are mounted on the housing in a state of abutting each other in predetermined directions. The terminals supported by the terminals supports mounted on the housing can form a gap where a contacted object is inserted, between the contacts of the terminals in a direction along the abutment directions of the paired terminal supports.

  • Patent number: 10490946
    Abstract: In a typical connector, one or more ground terminals need to be, in addition to signal terminals, arranged between signal terminals formed in pairs or between one signal terminal pair and the other signal terminal pair. This leads to a problem that the number of components forming the connector is increased and an internal structure of the connector is complicated. A connector is provided, which is a substrate-side connector including two terminal groups arranged along a connector fitting direction to face each other, an insulator holding the terminal groups, and an outer conductor shell housing the insulator. In the substrate-side connector, a shell mounting portion for mounting the outer conductor shell on a substrate is, passing through between the two terminal groups, mounted between a mounting portion for a group of terminals of multiple terminals included in one terminal group and a mounting portion for a group of the terminals of multiple terminals included in the other terminal group.
