Definitions

  • the present invention relates to an electrical connector capable of releasing a locked state of a contact without using a separately prepared jig.
  • the electrical connector generally includes a lance within the cavity of the housing for locking and retaining the contact. After assembling the electrical connector, the contacts may be removed from the housing, for example for maintenance of the electrical connector. In order to remove the contact, the lance is displaced in the unlocking direction by a removal jig separate from the electrical connector to release the locked state between the contact and the lance, and then the contact is pulled backward. (For example, Patent Document 1).
  • Patent Document 2 proposes an electrical connector that can remove contacts without using a jig.
  • This electrical connector has a frame in which the housing is held at a predetermined holding position, and the frame is integrally provided with a release portion for displacing the lance in a direction for releasing the engagement with the contact.
  • patent document 2 in order to hold
  • the contact between the abutment portion and the abutment portion prevents the housing from being inserted beyond the holding position of the frame.
  • the electrical connector of Patent Document 2 once removes the housing from the frame and bends the abutment portion to allow the housing to move relative to the frame in the forward direction relative to the holding position. Thereafter, when the housing is inserted into the frame, the housing moves relative to the front of the holding position without stopping at the holding position. Due to the excessive movement of the housing, the release portion abuts on the lance to displace the lance in the unlocking direction.
  • an object of this invention is to provide the electrical connector which can remove a contact from a housing efficiently, without using a jig.
  • the electrical connector of the present invention is provided in a contact electrically connected to a mating contact, a housing in which a cavity for accommodating the contact is formed, and a cavity for locking the contact.
  • the fitting surface side connected to the mating connector is defined as the front
  • the side from which the electric wire is derived is defined as the rear. The same applies to the embodiments to be described later.
  • the lock release member includes a drive unit involved in the lock release and an operation unit connected to the drive unit and operated during movement, and the drive unit advances and retracts the path. Is more preferred. If the operation unit is present, the operator can easily move the lock release member by performing an operation such as pushing the operation unit.
  • the unlocking member is attached to the housing so as to be movable back and forth between a first position on the front side and a second position on the rear side.
  • the lance is displaced in a direction to unlock the contact by applying a load from the unlocking member to the lance.
  • the load on the lance is released from the unlocking member, whereby the lance locks the contact. Since this electrical connector can grasp that the contact is locked or unlocked depending on the position (first position, second position) of the unlocking member, the worker performs the work of removing and attaching the contact. Can be done reliably.
  • the present invention can be applied to an electrical connector provided with a plurality of contacts and a plurality of lances that lock the plurality of contacts and hold the contacts out of the cavity. In that case, by providing a plurality of integrated unlocking members, it is possible to simultaneously unlock the plurality of contacts by a single unlocking operation.
  • the present invention can further include a cover attached to the housing and covering the lock release member. By covering the locking release member with the cover, it is possible to prevent the locking release member from being inadvertently moved to release the locking.
  • the lock release member includes the operating portion, at least the operating portion is preferably covered with a cover for preventing inadvertent movement.
  • the locked state of the contact can be released by operating the lock release member attached to the housing, it is not necessary to use a jig for removal.
  • the locked state of the contact and the lance can be released simply by moving the locking release member from the rear to the front while the contact is locked. Work efficiency of the removal of Furthermore, since the electrical connector of the present invention can perform the removal operation of the contacts only on the lead-out side of the electric wire, the workability of the removal of the contacts is excellent.
  • the electrical connector 1 includes a housing 10 for holding a contact 100 connected to the tip of the electric wire 110 of the cable 105, a lock ring 30 for locking the contact 100 and retaining it, and a presser for fixing the lock ring 30 to the housing 10.

Each main body 52 is formed with a cylindrical through hole 54 penetrating in the front-rear direction. In the through hole 54, the drive portion 72 of the locking release member 70 is disposed so as to be relatively movable in the front-rear direction.
