Connector, Electric Wire with Connector, and Medical Device Sensor
First Claim
1. A connector, comprising:
- a connector terminal comprising a terminal base portion to which an electric wire is connectable, and an electric connector that extends from the terminal base portion and to which a mating terminal pin is detachably connected; and
a connector housing comprising a terminal insertion portion through which the mating terminal pin P is insertable, and a terminal housing portion in which the connector terminal is housed in a state where the electric connector is directed to the terminal insertion port and held in engagement with the connector housing,the terminal housing portion comprising a tubular inner surface surrounding the electric connector,the electric connector comprising three or more flat plate-shaped elastic contact pieces arranged at intervals from each other around a central axis of the tubular inner surface inside the tubular inner surface,each of the three or more elastic contact pieces comprising;
a contact portion that extends along the central axis and is curved to project toward the central axis, a base portion that extends from the contact portion toward the terminal base portion and is directly or indirectly connected to the terminal base portion; and
a distal end portion that extends from an end portion opposite to the base portion of the contact portion and is positioned outward in a direction orthogonal to the central axis of the contact portion, andthe contact portion being configured to be subjected to a pressing force from the mating terminal pin toward the tubular inner surface when the mating terminal pin is inserted through the terminal insertion port into the connector housing, and to be thereby elastically deformed from a curved form to a flat form so as to move a distal end edge of the distal end portion toward the terminal insertion port in a state where the distal end portion is held in contact with the tubular inner surface.

Abstract
Provided is a connector including a connector terminal to which a mating terminal pin is connected and a connector housing configured to house the connector terminal therein. The connector housing has a tubular inner surface surrounding the connector terminal. The connector terminal includes elastic contact pieces arranged at intervals around a central axis of the tubular inner surface. Each elastic contact piece includes a contact portion extending along the central axis and being curved and a distal end portion located outward in a direction orthogonal to the central axis of the contact portion. The contact portion, when subjected to a pressing force from the mating terminal pin toward the tubular inner surface, is shaped into a flat form as a result of the distal end portion moving along the tubular inner surface. Also provided are an electric wire with the connector and a medical device sensor.
