Abstract

A plug terminal block structure for plugging a wire includes an insulated base, a conductive spring plate and a metal terminal. The insulated base has a cavity and a wire inlet for inserting and connecting the wire. The wire inlet has a wire arm and an embedded slot. A fixed portion is formed in the cavity. The conductive spring plate is installed in the cavity and has a clamping arm formed in the wire inlet. The metal terminal includes a riser, and a pin connected to the riser and embedded into the embedded slot and formed on a side of clamping arm. Both of the riser and wire arm are stopped at the conductive spring plate and a side of the wire. Therefore, the wire will not be exposed, and the conductive spring plate can be limited stably in the cavity to improve the safety of use.

First claim

What is claimed is:

1. A plug terminal block structure, for plugging a wire, comprising:
an insulated base, having a cavity, a wire inlet communicating with the cavity and provided for plugging the wire, a wire arm formed at a side of the wire inlet, an embedded slot formed on the other side of the wire inlet, and a fixed portion formed in the cavity;
a conductive spring plate, installed in the cavity and configured to be corresponsive to the fixed portion, and having a clamping arm formed in the wire inlet; and
a metal terminal, comprising a riser, a pin coupled to an end of the riser and embedded into the embedded slot and formed on a side of the clamping arm, and both of the riser and the wire arm being blocked by the conductive spring plate and a side of the wire.

2. The plug terminal block structure as claimed in claim 1 , wherein the cavity has a window, and the wire arm and the insulated base are integrally formed on a side of the window.

3. The plug terminal block structure as claimed in claim 1 , wherein the wire arm has a free end formed on a side of the insulated base, and a step block is disposed on a surface of the free end, and the riser has a step slot configured to be corresponsive to the step block and coupled to the step block.

4. The plug terminal block structure as claimed in claim 1 , wherein the fixed portion comprises a spring plate bracket and a spring plate slot formed between the outer periphery of the spring plate bracket and the insulated base, and the conductive spring plate further comprises a fixed arm and an arcuate section extending from the fixed arm, and the clamping arm extends from an end of the arcuate section away from the fixed arm, and the arcuate section is embedded into the spring plate slot and clamped between the spring plate bracket and the insulated base.

5. The plug terminal block structure as claimed in claim 4 , wherein the insulated base has a horizontal slot communicating with the cavity, and the metal terminal further comprises a horizontal plate extending curvedly from the riser and embedded into the horizontal slot, and the fixed arm has an end electrically coupled to an end of the horizontal plate.

6. The plug terminal block structure as claimed in claim 5 , further comprising a plurality of through holes formed at the curvedly connected positions of the horizontal plate and the riser, and the riser having a reinforcing rib and a chamfer disposed at a corner end of the riser.

7. The plug terminal block structure as claimed in claim 1 , wherein the embedded slot separates the wire arm and the insulated base from each other.

8. The plug terminal block structure as claimed in claim 1 , further comprising a plurality of engaging teeth of the pin facing a side of the clamping arm and a latch formed at the top of each engaging teeth and provided for engaging an end of the clamping arm.

9. The plug terminal block structure as claimed in claim 1 , further comprising a release member, a release member jack disposed at the insulated base on a side of the wire inlet and communicating with the cavity, the release member being plugged and coupled to the release member jack for pushing the clamping arm to produce an elastic deformation.

10. The plug terminal block structure as claimed in claim 9 , wherein the release member comprises a block member and a wedge extending from the block member, a limit portion disposed in the release member jack for restricting the downward movement of the block member.

11. The plug terminal block structure as claimed in claim 10 , wherein the release member jack has a stop plate installed therein, and the wedge has a stop portion disposed at a middle section thereof and engaged with and blocked by the stop plate.
