The fixed end slot and the movable end slot of the product are put on the track to achieve installation of the product on the track, and the product can be removed from the track by moving the movable end.

[0003] Related technologies such as a track-type terminal block with improved structure disclosed in a Chinese patent with announcement number CN219811673U include a terminal housing, a clamping structure for clamping a guide rail is provided on the terminal housing, the clamping structure includes a fixed hook, a movable hook and a track limit stopper, a T-shaped open groove structure matching the guide rail is formed between the surface of one end of the terminal housing and the convex stopper of the fixed hook and the movable hook, and the track limit stopper is fixedly arranged on the other side of one end of the terminal housing, and the track limit stopper can prevent the guide rail connected to the terminal housing from sliding along the width direction of the T-shaped open groove structure

[0004] With respect to the above-mentioned related technologies, the applicant believes that the above-mentioned rail-type terminal blocks have only one conductive sheet inside, which only meets the one-in-one-out requirement. When there are more wiring requirements in actual work, multiple terminal housings need to be combined together for use, and a corresponding clip-on structure needs to be set on each terminal housing. The cost of consumables is relatively high, and therefore needs to be improved. Summary of the invention

[0005] The purpose of the present application is to provide a modular rail-type terminal block that can reduce the consumables cost of the terminal housing under the condition of multiple wiring requirements.

[0006] The present application provides a modular rail-type terminal block, which adopts the following technical solution:

[0007] A modular track-type terminal block comprises a terminal housing, a conductive structure and a track clamp, wherein the terminal housing comprises a bottom shell and a cover body, wherein the upper side of the bottom shell is open, the conductive structure is installed in the bottom shell, the cover body is covered on the bottom shell, and a plurality of wiring ports are arranged on the cover body. Both sides of the bottom of the terminal housing are provided with clamping grooves arranged along the length direction of the terminal housing, and both ends of the top surface of the track clamp are provided with clamping portions that can be clamped with the clamping grooves, wherein the conductive structure is arranged in a plurality of pieces along the length direction of the terminal housing.

[0008] By adopting the above technical solution, multiple conductive structures can be installed into the bottom shell according to actual requirements, and then the cover body is covered to achieve the effect of restricting the conductive structures within the terminal shell. Subsequently, by utilizing the cooperation between the card slot and the clamping portion, the detachable connection between the track clamping member and the terminal shell can be realized, so that the terminal shell can be fixed on the clamping track by the track clamping member. With this design, at most only two track clamping members are required to adapt to the fixation and use of the terminal shell with multiple conductive structures.

[0009] Optionally, a thickening portion is provided on the bottom surface of the bottom shell. Ribs extending along the length direction of the thickening portion are provided on both opposite side surfaces of the bottom of the thickening portion.

[0012] By adopting the above technical solution, by utilizing the cooperation between the limiting protrusions and the limiting grooves, the connection strength between the bottom shell and the track clamping member can be improved, so that when the terminal shell is installed on the clamping track through the track clamping member, the terminal shell is not easily detached due to vibration.

[0013] Optionally, through grooves are provided at both ends of each track clamping member. A connecting piece is provided inside the bottom of the through groove. Both ends of the connecting piece are integrally connected to the two opposite side surfaces of the through groove. The two limiting protrusions are respectively provided on the upper surfaces of the two connecting pieces.

[0015] Optionally, a first dovetail groove is provided at the upper end of one short side surface of the cover body. The upper end of the first dovetail groove communicates with the upper surface of the cover body. A first dovetail block is provided at the upper end of the other short side surface of the cover body.

[0017] Optionally, a second dovetail groove located below the first dovetail block is provided at the lower end of one of the short side surfaces of the bottom case. The lower end of the second dovetail groove communicates with the bottom surface of the bottom case. A second dovetail block is provided at the upper end of the other short side surface of the bottom case. Between the lower ends of two adjacent terminal housings, they can be snap-connected and combined through the second dovetail groove and the second dovetail block.

[0018] By adopting the above technical solution, the cooperation between the second dovetail groove and the second dovetail block can achieve the effect of connecting the lower ends of any two adjacent terminal housings together. When used in combination with the first dovetail groove and the first dovetail block, the connection strength between any two adjacent terminal housings can be further improved.

[0019] Optionally, an inner groove is provided on one of the short side surfaces of the cover body, and a convex portion is provided at the upper end of the other short side surface of the cover body. When two adjacent cover bodies are combined, the connection can be strengthened through the inner groove and the convex portion.

[0020] By adopting the above technical solution, the cooperation between the inner groove and the convex portion makes it difficult for the two terminal housings to fall off and separate due to vibration when any two adjacent terminal housings are connected.

[0021] Optionally, a plurality of positioning protrusions are provided on both long side surfaces of the bottom case, and a plurality of positioning grooves are provided on both long side surfaces of the cover body. When the cover body is covered on the bottom case, the positioning protrusions are respectively clamped in the positioning grooves.

[0022] By adopting the above technical solution, the cooperation between the positioning protrusion and the positioning groove can increase the connection strength between the cover body and the bottom case, making it difficult for the cover body and the bottom case to separate, and ensuring the safe use of the terminal housing.
