[0028] The following is in conjunction with the appendix Figure 1-3 This application will be described in further detail.

[0029] This application discloses a terminal block.

[0030] Reference Figure 1 and Figure 2 The terminal block includes a mounting base 1, multiple connectors 2 and multiple clamping bases 3. Multiple mounting slots 11 are provided on the upper side of the mounting base 1. The multiple mounting slots 11 are spaced apart along the width direction of the mounting base 1. The mounting base 1 has a first snap-fit ​​slot 12 and a wire-passing slot 13 at both ends of each mounting slot 11.

[0031] The number of connectors 2 is the same as the number of mounting slots 11, and multiple connectors 2 are spaced apart along the width direction of the mounting base 1 so that each connector 2 is installed in each mounting slot 11. Specifically, the connector 2 includes a connecting spring 21 and two conductive springs 22. The two conductive springs 22 are respectively installed at both ends of the connecting spring 21, and the connecting spring 21 and the two conductive springs 22 are all engaged in the mounting slot 11.

[0032] The clamping seat 3 has two protruding first locking blocks 31. The clamping seat 3 passes through the mounting groove 11, so that the two first locking blocks 31 are respectively locked in the two first locking grooves 12, so that the connecting spring 21 and the conductive spring 22 are both limited between the mounting seat 1 and the clamping seat 3.

[0033] Both ends of the clamping seat 3 are rotatably connected to the button 4. The wire extends into the mounting groove 11 through the wire groove 13. By rotating the button 4, the wire is pressed between the button 4 and the conductive spring 22 to achieve the connection between the two wires.

[0034] In practical applications, before assembling the terminal block, two conductive springs 22 are respectively connected to both ends of the connecting spring 21, that is, the connector 2 is installed as a whole. During the terminal block assembly process, the connector 2 is first placed in the mounting groove 11 and the connecting spring 21 is pressed, so that the connecting spring 21 and the two conductive springs 22 are engaged in the mounting groove 11. Then, the clamping seat 3 is pressed and extended into the mounting groove 11, so that the first locking blocks 31 at both ends of the clamping seat 3 are engaged in the two first locking slots 12, thereby limiting the connecting spring 21 and the two conductive springs 22, so that the connecting spring 21 and the conductive springs 22 are both limited between the mounting seat 1 and the clamping seat 3, thus completing the terminal block assembly. This operation is simple and convenient, thereby facilitating the assembly of the terminal block.

[0035] Reference Figure 2 and Figure 3In some embodiments, the conductive spring 22 is arranged in a "V" shape, with the lower end of the conductive spring 22 snapped into the connecting spring 21 and the upper end of the conductive spring 22 abutting against the connecting spring 21, so as to realize the connection between the conductive spring 22 and the connecting spring 21, so as to facilitate the assembly of the connector 2, and under the elastic action of the conductive spring 22, the stability of the assembly of the connector 2 can be effectively guaranteed.

[0036] Reference Figure 2 In some embodiments, the lower side of the first snap-fit ​​block 31 is provided with a chamfer 32. When the clamping seat 3 extends into the mounting groove 11, the chamfers 32 at both ends of the clamping seat 3 abut against the mounting seat 1, so that the two ends of the clamping seat 3 deform inward, so that the clamping seat 3 can extend into the mounting groove 11. Under the action of the chamfer 32, the first snap-fit ​​block 31 can be snapped into the first snap-fit ​​groove 12, thereby facilitating the installation of the clamping seat 3 and further facilitating the assembly of the wiring terminal.

[0037] Reference Figure 1 and Figure 2 In some embodiments, the clamping seat 3 has protruding second locking blocks 33 on both sides. Correspondingly, the mounting seat 1 has second locking grooves 14 on both sides of each mounting groove 11. Each second locking block 33 is engaged in each second locking groove 14 to improve the stability of the clamping seat 3 installed on the mounting seat 1, thereby improving the stability of limiting the connection spring 21 and the two conductive springs 22, and thus ensuring the stability of the terminal block.

[0038] In some embodiments, the upper side of the mounting base 1 is provided with a plurality of clearance grooves 15 for a plurality of second snap-fit ​​blocks 33 to pass through. When the clamping seat 3 extends into the mounting groove 11, each second snap-fit ​​block 33 passes through each clearance groove 15 so that the clamping seat 3 can extend into the mounting base 1 and play a positioning role in the installation of the clamping seat 3, further facilitating the installation of the clamping seat 3.

[0039] In some embodiments, a test hole 34 is provided on the upper side of the clamping seat 3. The test hole 34 is provided through the terminal block, and the test pen contacts the connecting guide plate through the test hole 34 to facilitate testing the operation of the terminal block.

[0040] In some embodiments, the upper side of the mounting base 1 is provided with a plurality of mounting holes 16 for bolts to pass through, so that the bolts cooperate with the mounting holes 16 to install the terminal block on the panel, thereby facilitating the installation of the terminal block.

[0041] In some embodiments, the terminal block further includes a plurality of mounting clips 5, which are spaced apart along the width direction of the mounting base 1, and each mounting clip 5 is detachably connected to the mounting base 1. The mounting clips 5 can be connected to the terminal rail to realize the installation of the terminal block, so that the terminal block can be installed in different ways to improve the applicability of the terminal block.

[0042] In some embodiments, the two ends of the mounting buckle 5 are engaged with two first snap-fit ​​slots 12 to achieve a detachable connection between the mounting buckle 5 and the mounting base 1, which is simple in structure and easy to operate.

[0043] In some embodiments, the mounting base 1 is embedded in the mounting clip 5 to improve the stability of the connection between the mounting clip 5 and the mounting base 1.

[0044] The implementation principle of this embodiment is as follows: In practical applications, before assembling the terminal block, two conductive springs 22 are respectively connected to both ends of the connecting spring 21, that is, the connector 2 is installed as a whole. During the assembly of the terminal block, the connector 2 is first placed in the mounting groove 11 and the connecting spring 21 is pressed, so that the connecting spring 21 and the two conductive springs 22 are engaged in the mounting groove 11. Then, the clamping seat 3 is pressed and extended into the mounting groove 11, so that the first locking blocks 31 at both ends of the clamping seat 3 are engaged in the two first locking grooves 12, thereby limiting the connecting spring 21 and the two conductive springs 22, so that the connecting spring 21 and the conductive springs 22 are both limited between the mounting seat 1 and the clamping seat 3, thus completing the assembly of the terminal block. This operation is simple and convenient, thereby facilitating the assembly of the terminal block.
