Abstract

This disclosure is a terminal block. An insulative base includes an accommodating space and an insertion hole. The insulative base includes a lateral opening. A guiding structure is disposed in the accommodating space and includes a guiding plate and a guiding arm. A passing space is formed between the insulative base and the guiding plate. An L-shaped space is formed between the guiding plate and the insulative base. A U-shaped space is formed between the guiding arm and the insulative base. A conducting terminal is positioned in the L-shaped space. An elastic strip includes an abutting section, a positioning section and a U-shaped section connected therebetween. The elastic strip is inserted to the passing space and the U-shaped space to be connected with the guiding arm.

First claim

What is claimed is:

1. A terminal block inserted by at least one wire, the terminal block comprising:
an insulative base, comprising an accommodating space and an insertion hole communicating with the accommodating space, an extending direction of the insertion hole aligned along an inserting direction in the accommodating space, and the insulative base comprising a lateral opening disposed on a side surface, wherein a normal line of the side surface is perpendicular to the inserting direction;
a guiding structure, disposed in the accommodating space, comprising a guiding plate and a guiding arm connected to the guiding plate, wherein a passing space is disposed between the insulative base and a top of the guiding plate facing the insertion hole, an L-shaped space is disposed between two adjacent sides of the guiding plate and the insulative base, and a U-shaped space is disposed between two adjacent sides of the guiding arm and the insulative base;
a conducting terminal, positioned in the L-shaped space; and
an elastic strip, comprising an abutting section, a positioning section and a U-shaped section connected between the abutting section and the positioning section, and the elastic strip inserted to the passing space and the U-shaped space through the lateral opening to be connected with the guiding arm.

2. The terminal block of claim 1 , wherein the guiding structure and the insulative base are formed in one piece.

3. The terminal block of claim 1 , wherein the guiding plate is located adjacent to the insertion hole and extends along the inserting direction to cover part of the lateral opening.

4. The terminal block of claim 1 , further comprising an insertion rod, wherein the insulative base comprises a tool hole disposed on a side of the insertion hole, the tool hole communicates with the accommodating space, and the insertion rod is movably accommodated in the tool hole to press the abutting section and to position an end of the abutting section in one of the engaging slots.

5. The terminal block of claim 1 , wherein the guiding plate comprises an L-shaped plate, the top of the guiding plate comprises a slant, and the guiding arm aslant extends from the guiding plate.

6. The terminal block of claim 5 , wherein the guiding arm comprises an extending arm connected with the guiding plate, an annular bar and a neck portion disposed between the extending arm and the annular bar, and the U-shaped section of the elastic strip is placed around the annular bar and abuts against the neck portion.

7. The terminal block of claim 1 , wherein the conducting terminal comprises an engaging section and an extending section connected with the engaging section, and the engaging section comprises multiple engaging slots positioning the abutting section of the elastic strip.

8. The terminal block of claim 7 , wherein the guiding plate comprises a bottom plate extended toward an inside of the accommodating space, the bottom plate comprises a positioning block, the extending section of the conducting terminal comprises a positioning hole and a tab, and the insulative base comprises a positioning slot positioning the tab.

9. The terminal block of claim 1 , wherein an amount of the insertion hole is multiple, an amount of the guiding structure, an amount of the elastic strip and an amount of the conducting terminal are multiple corresponding to the amount of the insertion hole.

10. The terminal block of claim 9 , wherein the insertion hole, the guiding structure and the elastic strip are two in number respectively, the conducting terminal is of a U shape and comprises two engaging sections and an extending section connected between the two engaging sections.
