Definitions

  • the present invention relates to an electrical connector configured to retain a signal transmission medium by elastic engagement force of a lock member by inserting a terminal part of the signal transmission medium to a predetermined position in an insulating housing.
  • various electrical connectors are widely used as means for electrically connecting various signal transmission media such as flexible printed circuits (FPC) and flexible flat cables (FFC).
  • FPC flexible printed circuits
  • FFC flexible flat cables
  • a signal transmission medium composed of, for example, FPC or FFC is inserted from a front-end-side opening of an insulating housing (insulator) into the interior thereof, and an actuator (connection operating means) is then turned by operating force of an operator so as to be pushed down toward a connection working position in the front side or the rear side of the connector.
  • an actuator connection operating means
  • part of a lock member is put into an engaging part provided at a terminal part of the signal transmission medium to achieve an engaged state, and the terminal part of the signal transmission medium is configured to be retained in an approximately immobile state by the lock member.
  • an electrical connector having an actuator is configured to operate engagement/detachment of a lock member by carrying out operation to turn the actuator between a disconnecting position and a connection working position, wherein work efficiency is sometimes a problem since the actuator has to be operated separately from the operation to insert the signal transmission medium (for example, FPC, FFC). Therefore, for example, like below-described Patent Literature 2 and 3, an electrical connector provided with a so-called one-action automatic locking mechanism configured so that part of a lock member is elastically displaced so as to be placed over a signal transmission medium inserted into an insulating housing and that the part of the lock member is then put into an engaging part of the signal transmission medium to carry out engagement has been conventionally developed.
  • a signal transmission medium is retained in an approximately immobile state only by inserting the signal transmission medium to a predetermined position in the electrical connector, and work efficiency is improved.
  • the one-action automatic locking mechanism employed in conventional electrical connectors has an advantage that locking is carried out only by inserting a signal transmission medium (for example, FPC, FFC) into the electrical connector as described above; however, the configuration of a lock cancellation operating part for cancelling an engaged state of a latch lock part tends to be complex, the cancelling operation takes labor, and a problem may be caused in usage durability.

  • the board connecting part, the latch lock part, and the lock cancellation operating part are integrally provided with the lock arm member. Therefore, the retaining action and the cancelling action of the inserted signal transmission medium are carried out by operation of a single member, the structure and operation of the cancellation operating part are simplified, and usage durability is also improved.

  • the entire electrical connector is fixed in a state that is balanced from both sides, and firm retainability can be obtained with respect to external force caused by, for example, insertion of the signal transmission medium.

  • the lock cancellation operating part which is exposed to outside from the cut-away part of the insulating housing when insertion of the signal transmission medium is carried out well, is maintained in the state in which the operating part is buried inside of the insulating housing. Therefore, whether the insertion operation of the signal transmission medium is good or not can be easily determined.
  • the latch lock part and the lock cancellation operating part are integrally provided to the elastically-displaceable lock arm member integrally extending like a cantilever from the board connecting part solder-joined with the wiring board.
  • the board connecting part, the latch lock part, and the lock cancellation operating part are integrally provided to the lock arm member so that the retaining action and cancelling action of the inserted signal transmission medium are carried out by operation of a single member. Therefore, operability and usage durability of the lock cancellation operating part can be improved with a simple configuration, and reliability of the electrical connector can be significantly improved at low cost.

    où deux pièces d'encliquetage (12d) sont prévues en des positions appropriées d'une partie de bord de l'élément de verrouillage (12) de manière à faire saillie depuis l'élément de verrouillage (12) dans la direction frontale du connecteur du support de transmission de signal (F), de sorte que la fixation de l'élément de verrouillage (12) est réalisée quand les pièces d'encliquetage (12d) sont engagées dans le boîtier isolant (11),
    où la pièce de fixation (12f) forme une marche entre la plaque de base inférieure (12b) dans la direction de haut en bas perpendiculaire à la carte de câblage,
    où la partie de cliquet de verrouillage (12a) est agencée au niveau d'une position frontale plus proche de la partie courbe (12g1) par rapport à la position centrale entre la partie courbe (12g1) et la partie d'actionnement d'annulation de verrouillage (12e), de sorte que la distance entre la partie courbe (12g1) et la partie d'actionnement d'annulation de verrouillage (12e) est plus grande que celle entre la partie courbe (12g1) et la partie de cliquet de verrouillage (12a).
