Definitions
- the present invention relates to an electrical connector configured to perform clamping by pressing a contact member so as to be sandwiched from both sides of a flat signal transmission medium inserted into an insulating housing.
- a flat signal transmission medium such as a flexible printed circuit (FPC) or a flexible flat cable (FFC) in various electrical devices and apparatuses.
- FPC flexible printed circuit
- FFC flexible flat cable
- Various electrical connectors are widely used for electrical connection.
- an electrical connector that is mounted on a printed wiring board and used includes an FPC, an FFC, or the like from a medium insertion opening provided at a front end portion of an insulating housing (insulator).
- a flat signal transmission medium is inserted.
- the flat signal transmission medium is inserted so as to be sandwiched between the lower beam and the upper beam constituting the contact member.
- the contact member is elastically displaced by, for example, an actuator (connection operation means) being rotated by the operator's operation force, and the upper and lower beams of the elastically displaced contact member are converted into a flat signal transmission medium.
- the flat signal transmission medium is clamped by being in a pressure contact state on both front and back surfaces (FPC, FFC, etc.).
- the contact member is electrically connected to the signal pattern provided on the flat signal transmission medium.
- the Rukoto As a result, the flat signal transmission medium is electrically connected to the wiring board through one end of the contact member soldered to the conductive path on the wiring board, and signal transmission via the electrical connector is performed. Done.
- contact members arranged in a multipolar manner tend to be arranged at a narrow pitch with the progress of significant miniaturization and low profile.
- the conductor resistance of the contact member increases, and thereby heat generation may cause a temperature rise of the electrical connector.
- a configuration in which one transmission signal is energized to a plurality of contact members may be employed as a means for reducing the conductor resistance of the contact members. According to such an energization structure with a plurality of contact members, it is possible to suppress an increase in temperature during signal transmission.
- an object of the present invention is to provide an electrical connector having a simple configuration and capable of easily avoiding an increase in length and height even when relatively large power is supplied.
- a plurality of contact members attached to an insulating housing are arranged in a multipolar shape along the thickness direction of the contact members,

- a configuration is adopted in which at least the integral thickness of the plurality of contact members is thicker than the other contact members.
- the conductor resistance of the thick contact member with the increased thickness is reduced according to the increase in thickness, so that the energization allowable power of the electrical connector is increased, Since it is not necessary to increase the number of contact members even when the power supplied to the connector is relatively large, an increase in the size or height of the electrical connector is suppressed. Further, when the contact portion of the thick contact member having increased thickness is pressed against the flat signal transmission medium inserted into the insulating housing, the contact pressure of the contact member with respect to the flat signal transmission medium increases. As a result, the retention of the flat signal transmission medium is improved.
- two contact members formed thicker than the other contact members are arranged so as to sandwich the other contact members in the multipolar arrangement direction.
- the contact portion of the two contact members that realizes a relatively large contact pressure with respect to the flat signal transmission medium by increasing the thickness is different from the other contact members. Since the flat signal transmission medium is pressed against the flat signal transmission medium in such a manner that the flat signal transmission medium is rotated, the positional deviation of the flat signal transmission medium in the plane including the surface of the flat signal transmission medium is prevented.
- the two contact members are disposed at the outermost positions on both sides in the multipolar arrangement direction.
- the contact portions of the two contact members that realize a relatively large contact pressure with respect to the flat signal transmission medium by increasing the thickness are arranged in a multipolar arrangement. Since the flat signal transmission medium is pressed against the flat signal transmission medium at the outermost position on both sides in the direction, that is, at the outer edge positions on both sides in the width direction of the flat signal transmission medium, the flat signal transmission The positional deviation in the rotation direction of the medium can be prevented even better.
- the distance S between the pair of contact portions provided on the contact member formed thicker than the other contact member is set to be equal to or smaller than the thickness T of the flat signal transmission medium. (S ⁇ T) is desirable.
- the flat signal transmission medium immediately after being inserted into the insulating housing immediately comes into contact with the contact portion of the thick contact member having an increased thickness. For this reason, the flat signal transmission medium is temporarily held by the relatively large contact pressure of the contact portion of the thick contact member, and the flat signal transmission medium is inserted from the insertion of the flat signal transmission medium until the clamping is completed. The signal transmission medium is stably held.
- the other contact member and the contact member formed thicker than the other contact member have the same shape when viewed in the multipolar arrangement direction. Is desirable.
- a thick contact member having an increased thickness is assembled in the same manner as other contact members.
- each of the plurality of contact members including the other contact member and the contact member formed thicker than the other contact member is mutually viewed when viewed in the multipolar arrangement direction. It is desirable that the contact member is formed from one of two types of contact members having different shapes.
- thick contact members with increased thickness are mixed in a multipolar arrangement direction, for example, so-called staggered arrangement in which the contact members are alternately arranged.
- the configuration can be adopted.
- the conductor resistance of the contact member having an increased thickness is increased by forming at least the integral thickness of the plurality of contact members thicker than the other contact members. Therefore, even if the power supplied to the electrical connector is relatively large, it is not necessary to increase the number of contact members, and an increase in the size of the electrical connector, such as an increase in the length or height of the electrical connector, can be suppressed. .
- the electrical connector according to the present invention is configured to press the contact member having an increased thickness against the flat signal transmission medium inserted into the insulating housing, thereby reducing the contact pressure of the contact member against the flat signal transmission medium.
