Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and specifically to a terminal block. Background Technology

[0002] Currently, conventional terminal blocks with fuses have the following problems when the fuse blows:

[0003] The inability to visually determine the status of the fuse increases the difficulty of troubleshooting.

[0004] Because the fuse holder is designed to be deep, it is difficult to replace the fuse by hand and tools must be used, which reduces maintenance efficiency.

[0005] The existing wiring method connects all positive and negative wires to different areas, with positive wires using terminals with fuses and negative wires using terminals without fuses. This design makes the correspondence between positive and negative wires unclear, making it difficult to quickly identify which two wires belong to the same group, which brings inconvenience to maintenance and repair work. Utility Model Content

[0030] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of the invention. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

They are used only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0032] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0033] like Figures 1-4 As shown, this utility model discloses a terminal block, including a main body 1. The main body 1 has a positive electrode 2 and a negative electrode 3 belonging to the same group. The positive electrode 2 and the negative electrode 3 are respectively provided with wiring holes on the outer side wall of the main body 1. The positive electrode 2 and the negative electrode 3 at the wiring holes are respectively threaded with wire clamping screws 4. The arrangement direction of the wire clamping screws 4 is perpendicular to the axis of the wiring holes. The main body 1 is provided with a through hole 5 at a corresponding position to accommodate the wire clamping screws 4. A screwdriver can be inserted into the through hole 5 to tighten the wire clamping screws 4.

[0034] The positive electrode 2 is broken in the middle into two parts. The broken part is used to accommodate the fuse 9. Each end of the fuse 9 is secured with a locking block 10, and the two locking blocks 10 are connected to the two parts of the positive electrode 2 respectively. The outer wall of the main body 1 on the side of the two locking blocks 10 and the fuse 9 is provided with a slot 7. The slot 7 exposes the two locking blocks 10 and the fuse 9. The two ends of the fuse 9 can be locked into the space between the two locking blocks 10, or the fuse 9 can be removed from the space between the two locking blocks 10.

[0035] A slot 8 is also provided on the outer wall of the main body 1 on the side of the slot 7. The slot 8 is connected to the slot 7 and has the same depth. A push block 11 is slidably provided in the slot 8. The push block 11 is inclined near the side wall of the slot 7. The end of the inclined surface away from the end of the slot 7 is the high end. The push block 11 slides into the slot 7 so that its inclined surface can enter the lower part of the safety 9. As the sliding proceeds, the inclined surface of the push block 11 can lift the safety 9 upward, scoop up the safety 9, and make the safety 9 disengage from the two end blocks 10.

[0036] Specifically, the inclined surface of the push block 11, from low to high, includes a first inclined section, a second inclined section, and a third inclined section in sequence. The first and second inclined sections mainly fit into the lower space of the safety 9. The first and second inclined sections are located at the lower part and the lower side of the safety 9, respectively. The angle between the first inclined section and the bottom surface of the slot 7 or the retaining groove 8 is smaller than the angle between the second inclined section and the bottom surface of the slot 7 or the retaining groove 8. The third inclined section is used to push the safety 9 up. The angle between the third inclined section and the bottom surface of the slot 7 or the retaining groove 8 is smaller than the angle between the second inclined section and the bottom surface of the slot 7 or the retaining groove 8.

[0037] A protrusion 14 is provided on each of the two side walls between the slot 7 and the slot 8. A baffle 12 is connected to the top of the push block 11 on the side away from the safety 9. A horizontally arranged spring 13 is connected between the baffle 12 and the protrusion 14. The spring 13 is arranged parallel to the sliding direction of the push block 11. When the push block 11 is not subjected to external force, the elastic force of the spring 13 pushes the push block 11 to slide away from the safety 9 until the push block 11 contacts the side wall of the slot 8.

[0038] A transparent cover (not shown in the figure) can be provided on the main body 1 to cover the card slot 8 and the slot 7. The cover can be hinged to the main body 1. After the safety 9 is installed, the cover is covered. When the safety 9 is replaced, the cover can be opened to remove and install the safety 9.

[0039] The bottom of the main body 1, that is, the side wall of the main body 1 opposite to the slot 7, is provided with a buckle 6 that cooperates with the guide rail.

[0040] This utility model features a slot 7 that exposes the fuse 9, allowing the status of the fuse 9 to be viewed through the slot 7, reducing the difficulty of troubleshooting. When removing or installing the fuse 9, pushing the baffle 12 causes the push block 11 to slide toward the fuse 9, which can lift the fuse 9 and detach it from the positive electrode 2. Releasing the baffle 12 allows the push block 11 to return to its original position under the elastic force of the spring 13. When installing the fuse 9, simply press the fuse 9 into the two locking blocks 10 of the positive electrode 2. This makes the removal and installation of the fuse 9 convenient, requiring no tools and can be done by hand, improving maintenance efficiency. The positive electrode 2 and negative electrode 3 belonging to the same group are set in the same main body 1, and the correspondence between the positive electrode 2 and the negative electrode 3 is clear, facilitating maintenance and repair work.

[0041] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the technical solutions of this utility model. Any technical solution that can be implemented based on the above embodiments without creative effort should be considered to fall within the scope of protection of this utility model patent.
