[0021] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0022] like Figures 1-4As shown, a pluggable terminal block includes an insulating base 1, an insulating cover plate 2 overlapping the rear of the insulating base 1, a plurality of linearly distributed sockets 11 extending through the insulating base 1 at the front, a plurality of linearly distributed sockets 23 extending through the insulating cover plate 2, a plurality of linearly distributed slots 13 at the top of the insulating base 1, a spring piece 5 placed at the rear of the inner cavity of the socket 11, a clip 4 extending through the top of the spring piece 5, the front of the clip 4 located at the rear of the inner cavity of the socket 23, and the front of the clip 4 located at the top of the rear inner cavity of the socket 11.
[0023] like Figures 1-4 As shown, the rear of the upper and lower surfaces of the insulating base 1 is provided with several linearly distributed slots 12, and the front of the upper and lower surfaces of the insulating cover plate 2 is fixedly connected with several linearly distributed locking blocks 24, and the inner wall of the slots 12 and the end of the locking blocks 24 are engaged.
[0024] The engagement between the locking block 24 and the locking slot 12 allows for the docking of the rear part of the insulating base 1 and the front part of the insulating cover plate 2, thereby enabling the assembly of the plug-in terminal block.
[0025] like Figure 1 and Figure 3 As shown, a button 3 that penetrates the top of the insulating base 1 is inserted into the inner cavity of the slot 13. The bottom of the button 3 overlaps with the top of the front side of the spring piece 5. The bottom of the button 3 has barbs on both sides.
[0026] Button 3 is used to press down the top of the front side of spring 5, which can achieve the snap-fit between the terminal block and the wire.
[0027] like Figure 1 and Figure 3 As shown, the top of the insulating base 1 has a test hole 6 that connects to the inner cavity of the socket 11. The test hole 6 is located between the bayonet 12 and the button 3.
[0028] The test hole 6 makes it more convenient for customers to conduct on-site testing.
[0029] like Figure 3 As shown, the front part of the lower surface of the clip 4 is provided with a barb, and the left and right sides of the inner cavity of the second insertion port 23 are fixedly connected with guide plates 25, which are located on the left and right sides of the rear part of the clip 4.
[0030] The barb enhances the connection between the wire and the bottom front side of the guide plate 25 and the front rear side of the spring piece 5, reducing the risk of the wire falling off. The guide plate 25 guides the wire inserted into the cavity of the socket 23 so that the front of the clip 4 can hold the wire.
[0031] like Figures 1-4As shown, the left and right ends of the top rear side of the insulating cover plate 2 are fixedly connected with buckles 21, and the upper surface of the rear side of the insulating cover plate 2 is provided with several linearly distributed sliding grooves 22.
[0032] By utilizing the cooperation between the latch 21 and the slide 22, the wiring terminal can be easily plugged into the corresponding interface, thus realizing the plugging and unplugging of the wiring terminal.
[0033] The working principle of this utility model is as follows: When assembling the pluggable terminal block, the spring piece 5 and the clip 4 are placed into the inner cavity at the rear of the socket 11 and the inner cavity at the front of the socket 23, respectively. The rear of the insulating base 1 and the front of the insulating cover plate 2 are then aligned and pressed down. This allows the locking block 24 to engage with the inner wall of the locking slot 12. Then, the button 3 is pressed down forcefully from the position of the slot 13 into the inner cavity of the socket 11, thus completing the assembly of the pluggable terminal block.
[0034] When in use, press down button 3 to press down the bottom of the front side of spring 5 and insert the wire from the front of socket 11. Then, release button 3 to fix the inserted wire at the top of the front side of spring 5 and the front side of the bottom of clip 4. The rear of insulating cover 2 can then be inserted into the corresponding position under the action of socket 23 and buckle 21 to realize the installation of plug-in terminal block. When in use, the position of test hole 6 makes it more convenient for customers to conduct on-site tests.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model.
