The present invention provides a flexible connection terminal including a flexible part made of a conductor, a terminal block, and a protective cover.
The terminal block has a convex cross section, and the end of the flexible portion is welded to the tip of the convex portion, and the protective cover is tube-shaped and encloses the flexible portion therein. This is a covered flexible connection terminal characterized in that an end portion is fixed to a stepped portion of the convex portion. If the protective cover is firmly connected to the terminal block at the stepped portion of the convex portion using an adhesive resin, a completely sealed state can be easily created. Reliability is further improved by covering the stepped portion to which the protective cover is fixed with a backing plate from the outside.

The figure is an overall external view of the embodiment of the present invention, in which 2 is a terminal block, 23 is a mounting hole, 3 is a protective cover, and 6 is a terminal block.
7 is a backing plate, and 7 is a pin for fixing the backing plate 6 to the terminal block 2. The protective cover 3 is tube-shaped with a substantially rectangular cross section, and is made of a material that is highly flexible and impervious to gas and liquid. A flexible portion (not shown) made of a conductor is housed inside the protective cover 3. FIG. 2 is a sectional view taken along the - line in FIG. 1, and FIG. 3 is a partially enlarged view thereof. Reference numeral 1 denotes a conductor, which is composed of an aggregate of thin wires or a laminate of thin conductors stacked vertically in the drawing. 21 is a convex portion of the terminal block, 22 is a stepped portion of the convex portion, 4 is a welded portion, 5 is an adhesive resin, and other symbols are the same as in FIG. 1. The conductor 1 is welded to the terminal block 2 at the welding part 4, which is the tip of the convex part 21, and electrically connected to the terminal block 2.
