Abstract

The contact state of a signal transmission medium and contact members is enabled to be maintained well by a simple configuration. Medium pressing portions of an actuator, which is subjected to a moving operation so as to electrically connect contact portions of contact members, which are in a multipolar arrangement, and a signal transmission medium (FPC, FFC, or the like) to each other, are disposed at the same positions as the contact portions of the contact members in the direction of the multipolar arrangement. The medium pressing portions of the actuator at the positions directly opposed to the contact portions of the contact members are configured to press the signal transmission medium when the actuator is moved to a working position so that the contact pressures applied from the medium pressing portions of the actuator to the signal transmission medium are reliably applied to the contact portions of the contact members without being dispersed.

First claim

What is claimed is:

1. An electric connector, comprising:
a plurality of contact members arranged to form a multipolar shape, each of the contact members including a contact portion; and
an actuator including a plurality of medium pressing portions, the actuator configured to move to a working position in a state in which a first-side surface of a signal transmission medium is disposed to face the contact portions of the plurality of contact members, thereby bringing the plurality of medium pressing portions into pressure-contact with a second-side surface of the signal transmission medium and electrically connecting the contact portions of the plurality of contact members with the signal transmission medium, wherein
the plurality of medium pressing portions are provided at a predetermined interval therebetween in a direction of the multipolar shape,
each medium pressing portion of the plurality of medium pressing portions is disposed at a position corresponding to a contact portion of a respective contact member, and
when the actuator is moved to the working position, the plurality of medium pressing portions and the contact portions of the plurality of contact members are disposed so as to be directly opposed to each other.

2. The electric connector according to claim 1 , wherein
a groove portion is provided at a recessed position on an intermediate part between the plurality of medium pressing portions mutually adjacent in the direction of the multipolar arrangement, and
when the actuator is moved to the working position, the groove portion is configured to be in a state in which the groove portion is not in contact with the surface of the signal transmission medium.

3. The electric connector according to claim 1 , wherein at least one of the medium pressing portions includes a deformation allowing portion that houses an elastically deformed part of the signal transmission medium when the contact portion of the corresponding contact member is brought into pressure-contact with the signal transmission medium.

4. The electric connector according to claim 1 , wherein
the actuator further includes a shaft portion extending along the direction of the multipolar shape, and
at least one contact member of the contact members includes a bearing portion that turnably supports the shaft portion of the actuator.

5. The electric connector according to claim 4 , wherein
the actuator further includes a bearing housing portion with a space that houses the bearing portion of the at least one contact member, and
the medium pressing portion corresponding to the at least one contact member is disposed at a same position as the bearing housing portion in the direction of the multipolar shape.

6. The electric connector according to claim 5 , wherein
the medium pressing portion, corresponding to the at least one contact member, further includes a deformation allowing portion that houses an elastically deformed part of the signal transmission medium when the at least one contact portion of the contact member is brought into pressure-contact with the signal transmission medium, and
the bearing housing portion is communicated with a deformation allowing portion.
