The guiding arm 22 includes an extending arm 221 connected to the guiding plate 21, a ring column 222 and a necking section 223 between the extending arm 221 and the ring column 222. The U-shaped section 43 of the spring 40 is sleeved on the ring post 222 and abuts against the necked section 223.

In an embodiment of the present invention, the connection terminal 30 includes a latching section 31 and an extending section 32 connected to the latching section 31. The latching section 31 is formed with a plurality of slots 310 capable of positioning the abutting section 41 of the spring plate 40.

It should be noted that, in the present embodiment, the guiding plate 21 extends toward the inner direction of the accommodating space 11 to form a bottom plate 214, and the bottom plate 214 has a positioning block 215 (see fig. 3). In addition, the extension 32 of the terminal 30 is formed with a positioning hole 321 and a protrusion 322. In addition, the insulating base 10 is formed with a positioning groove 14 capable of positioning the tab 322.

When the terminal block 1 of the present invention is assembled, the lead terminal 30 can be inserted into the L-shaped space 213 of the insulating base 10 from the side opening 13. At this time, the positioning hole 321 of the terminal 30 is engaged with the positioning block 215 of the insulating base 10 (see fig. 5). In addition, the protruding piece 322 abuts against the positioning slot 14 of the insulating base 10 (see fig. 4). Thereby, the lead terminal 30 is positioned in the L-shaped space 213.

In addition, when the elastic sheet 40 is assembled into the U-shaped space 220 from the side opening 13, the abutting section 41 thereof can first penetrate into the penetrating space 212 (refer to fig. 3), and then the U-shaped section 43 is sleeved on the ring column 222 of the guiding structure 20, and simultaneously the positioning section 42 is pressed to extend into the U-shaped space 220. Therefore, the elastic sheet 40 can be positioned on the guide arm 22 without being bent greatly. It should be noted that, in the state where the elastic sheet 40 is not pressed, the abutting section 41 extends into the insertion opening 12.

Please refer to fig. 6 and fig. 7, which are schematic views of the terminal block of the present invention with easy assembly of the spring plate. As shown in fig. 6, the terminal block 1 of the present invention is used for inserting at least one cable 2. In use, the plug 50 in the tool hole 15 is first forced to move downward. At this time, the plug 50 presses against the elastic sheet 40 and presses the abutting section 41 to separate from the insertion opening 12, so that the cable 2 can be inserted into the insertion opening 12 to electrically connect the connection terminal 30.

Referring to fig. 7, after the cable 2 is inserted to the positioning position, the force applied to the post 50 can be removed. At this time, the plug 50 is pushed by the restoring force of the elastic sheet 40 to move upward, and the abutting section 41 abuts against the cable 2 under the elastic force. Accordingly, the cable 2 is clamped between the connection terminal 30 and the elastic piece 40, and electrically connected to the connection terminal 30.

It is only above to do the preferred embodiment of the utility model, not for deciding the patent scope of the utility model, other applications the utility model discloses an equivalent change of patent spirit all belongs to the patent scope of the utility model.
