A first step hole 201 and a second step hole 202 are coaxially disposed in the riveting block 2 which is a riveted aluminum block. A diameter of the second step hole 202 is larger than a diameter of the first step hole 201. A stamped end of the terminal l successively passes through the bottom insulator 5, the top cover 4, the upper plastic insulator 3, the first step hole 201, and the second step hole 202. A part of the stamped end of the terminal 1 protruding from the first step hole 201 is stamped to form a protrusion ll located in the second step hole 202. id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14" id="p-14"

As shown in FIGS. 1 to 3, a ring-shaped protrusion 31 is disposed on a periphery of the second connecting hole 301, the ring-shaped protrusion 31 extends into the first connecting hole 40 and abuts the sealing ring 62, and the stamped end of the terrninal 1 successively passes through the third connecting hole 50, the first connecting hole 40, the second connecting hole 301, the first step hole 201, and the second step hole 202. id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18" id="p-18"
[0018] in this embodiment, as shown in FIG. 2, a placing groove 302 is defined on the upper plastic In order to facilitate placement of the riveting block 2 on the upper plastic insulator 3, insulator 3 and the riveting block 2 is located in the placing groove 302. id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19" id="p-19"
[0019] distributed with the second step hole 202 and an upper end of the protrusion 11 is located in the As shown in FIG. 2, the riveting block 2 is provided with a counterbore 203 coaxially second step hole 202. In other embodiments, the upper end of the protrusion 11 is located in the counterbore 203 and/or the second stepped hole 202. For example, after the riveting block 2 is welded to the protrusion 11, the upper end of the protrusion 11 may also be located in the counterbore 203 or a part of the upper end of the protrusion 11 is located in the counterbore 203 while another part of the upper end of the protrusion 11 is located in the second stepped hole 202. Thus, it is ensured that the protrusion 11 does not protrude from a surface of the riveting block 2, reducing the probability of causing cold joints between the protrusion 11 and the riveting block 2. In this embodiment, a diameter of the counterbore 203 is larger than a diameter of the second step hole 202, which makes it easier for a riveted stamping head to stamp the stamped end of the terrninal 1 downward. In this manner, the upper end of the protrusion 1 1 is recessed on the riveting block 2. id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20" id="p-20"
