Figure 1a is a perspective view of the hinge in its freely rotatable state, and Figure 1b is its perspective view. FIG. 2 is an exploded perspective view showing the rotation lock mechanism, which is the main part of the rotation locking state, FIG. 3 is a cross-sectional view taken along the - line in FIG. Each shows an example of the application of the hinge of the embodiment shown in Fig. 1 to an electrical connection device; Fig. 4a is a perspective view of the hinge in a freely rotatable state, and Fig. 4b is a perspective view of the hinge in a rotationally locked state. 5 is a view corresponding to FIG. 1b showing another embodiment of the present invention, and FIG. 6 is a plan view showing an example of application of a conventional hinge to an electrical connection device. In the figure, 1 is a hinge, 1A and 1B are plate pieces, 1
a, 1b are curled parts, 1d is a convex part, 1e is a concave part,
2 is the shaft, and C is the movable distance.

Claims

[Scope of utility model registration request]

A hinge in which a pair of plate pieces is formed with curled portions that are assembled together in a mortise-tenon shape on one side, and is hingedly connected by a shaft inserted through these curled portions. The axial length of the curled part is set to a length that allows it to move a predetermined amount in the axial direction with respect to the other curled part, and a convex part shorter than the movable distance is formed in the axial direction at one end. A hinge with a rotation locking function, characterized in that the end face of the other curled portion facing the convex portion is provided with a concave portion into which the convex portion can be fitted at a predetermined rotational angle position.
