Definitions

  • the present invention relates to an electric connector and electric connector assembly with a fit-in structure for electrically connecting any appropriate signal transmission medium to a main wiring board.
  • an electric connector is widely used for connecting a terminal part of a signal transmission medium formed of a flexible printed circuit (FPC), a flexible flat cable (FFC), a coaxial cable, or others to a main printed wiring board.
  • the electric connector is configured in a manner such that, to a first connector (a receptacle connector) mounted on a main printed wiring board, a second connector (a plug connector) to which a signal transmission medium such as a coaxial cable is inserted and both of the connectors fit in together.
  • Signal transmission is performed though conductive contacts (conductive terminals) arranged in a multipolar manner inside a body housing.
  • the structure has been conventionally adopted such that the outer surface of the body housing is covered with a metal-thin-plate-like conductive shell for electromagnetic shielding (refer to Japanese Unexamined Patent Application Publication No. 2007-73426 ).
  • the conventional electric connector has the structure such that only the outer surface of the body housing is covered with the conductive shell, and the terminal part of the conductive contacts (conductive terminals) described above, more specifically, a connecting portion with the main wiring board, is not covered with the conductive shell and is exposed to the outside. Therefore, with an increase in frequency of the transmission signal particularly in recent years, the influence of external electromagnetic noise on the connecting portion with the main wiring board has been becoming impossible to ignore, and the possibility of emission of electromagnetic noise from the connecting portion to the outside has been increasing.
  • a conductive tape is affixed to the connecting portion between the conductive contacts and the main wiring board, or the conductive shell is extended to cover that portion.
  • the connecting portion between the conductive contacts and the main wiring board cannot be checked by a visual inspection, an image inspection, or the like, thereby disadvantageously making it difficult to conduct an inspection and a check to see whether the connection works without any trouble.
  • a ground bar may be used to connect a plurality of coaxial cables arranged in a multipolar manner for spreading, and part of the conductive shell may be soldered to that ground bar.
  • a flux contained in a solder material is abruptly blown due to heating of the solder material, and therefore the solder material and the flux scatter to be adhered to a portion other than the originally-intended connecting portion, for example, a contact portion of the conductive contacts, thereby possibly causing an electrical problem.
  • EP 2 365 588 A1 relates to an electrical connector.
  • An electrical connector comprising an end portion of a flat circuit device which forms a connectively engaging protrusion on which a plurality of contacting terminals are arranged and a supporting board portion for supporting the connectively engaging protrusion, and first and second conductive shells having respectively first and second plate portions opposite to each other with the supporting board portion between, wherein the first conductive shell is attached to the supporting board portion with the first plate portion thereof covering directly a first surface of the supporting board portion and the second conductive shell is attached also to the supporting board portion with the second plate portion thereof covering directly a second surface opposite to the first surface of the supporting board portion, so that the first and second conductive shells are operative to hold the connectively engaging protrusion supported with the supporting board portion for causing the same to engage with a mating electrical connector.

Therefore, electromagnetic shielding of the connecting portion with the main wiring board is immediately performed simultaneously with the operation of rotating the fit-in holding member when both of the connectors fit in together, and therefore the number of manufacturing processes is not increased. Also, since the connecting portion with the main wiring board is not covered with the conductive cover part until the fit-in holding member is rotated to the fit-in acting position, the connection state at the connecting portion can be clearly confirmed.

    wobei irgendeine von den elektrischen Verbindereinrichtungen (1, 2) konfiguriert ist, um den Zustand des Einfügens bzw. Einpassens in der elektrischen Gegenstück-Verbindereinrichtung (2) beizubehalten.
  3. Elektrische Verbindereinrichtungsbaugruppe gemäß Anspruch 2, wobei irgendeine von den elektrischen Verbindereinrichtungen (1, 2) mit einem leitfähigen Kontakt (12) zur Verfügung gestellt wird, der einen Kontaktteil (12a) in Kontakt mit einem leitfähigen Kontakt (22) von der Gegenstück-Verbindereinrichtung (2) hat, und zwar zu der Zeit des Einfügens bzw. Einpassens in der Gegenstück-Verbindereinrichtung (2), wobei
    das Einfügungs- bzw. Einpassungshalteglied (14) konfiguriert ist, um wenigstens den Kontaktteil (12a) von dem leitfähigen Kontakt (12) abzudecken, wenn das Einfügungs- bzw. Einpassungshalteglied (14) in die bzw. zu der Einfügungs- bzw. Einpassungswirkposition in einem Zustand des Nichteinfügens bzw. Nichteinpassens in die Gegenstück-Verbindereinrichtung (2) gedreht wird.
  4. Elektrische Verbindereinrichtungsbaugruppe gemäß Anspruch 1, wobei
    das Einfügungs- bzw. Einpassungshalteglied (14) ein Paar von Koppelarmteilen (14b) enthält, die sich von drehbaren Schaftteilen bzw. Wellenteilen (14a) erstrecken, die an beiden Enden in einer Verbindereinrichtungslängsrichtung zur Verfügung gestellt werden, und einen Drehfunktionsteil (14c) enthält, der beide von den Koppelarmteilen (14b) verbindet, und
    wobei der Drehfunktionsteil (14c) mit dem leitfähigen Abdeckungsteil (14d) zur Verfügung gestellt wird.
  5. Elektrische Verbindereinrichtungsbaugruppe gemäß Anspruch 1, wobei
    wenn das Einfügungs- bzw. Einpassungshalteglied (14) in die Einfügungs- bzw. Einpassungswirkposition gedreht wird, ist der leitfähige Abdeckungsteil (14d') konfiguriert, um eine obere Oberfläche der Verbindereinrichtung und beide von den Seitenoberflächen der Verbindereinrichtung abzudecken.
