According to the thermocouple connector of the present invention, when the pin side connector and the end face side connector are brought close to each other, the plane of the electrode end face of the end face side connector is perpendicular to the electrode pins of the pin side connector. In the direction parallel to the electrode pins of the pin-side connector, a positional shift of up to the distance that the electrode pins of the pin-side connector can retreat is allowed, so damage during attachment / detachment is possible. , The accuracy of the positioning mechanism and the attachment / detachment mechanism required to prevent the above can be reduced.

Also, the fact that the electrode pins of the pin-side connector are pushed back by the electrode end faces of the end-face connector and retreats means that the impact when the tip of the electrode pin of the pin-side connector comes into contact with the electrode end face of the end-face connector is reduced. Since it can be absorbed, breakage at the time of attachment and detachment can be further prevented.

When the tip of the electrode pin of the pin-side connector has an R shape, the tip of the electrode pin of the pin-side connector is
Since there is always point contact with the electrode end face of the end face side connector, even if the relative positional relationship between the electrode pin of the pin side connector and the electrode end face of the end face side connector suddenly or temporally occurs. Since the electrical connection between the electrode pin of the pin-side connector and the electrode end surface of the end-face connector can always be made in a constant state, the reliability of temperature measurement by the thermocouple can be improved.

Further, the thermocouple connector of the present invention is used to electrically connect a lead wire of a thermocouple provided in a casting mold to a compensating lead wire of a measuring instrument installed in a facility to which the casting mold is attached and detached. When used for connection, the pin-side connector and the end-face-side connector need to be attached / detached every time the casting mold is attached / detached to / from the facility, so that the above-mentioned effects can be largely exerted.
