Description

Technical Field

[0001] This utility model relates to wiring terminals, specifically to a rail mounting structure for wiring terminals. Background Technology

[0002] An existing terminal block includes an insulating base and a wiring assembly. The wiring assembly includes a conductive plate and bolts and nuts installed at both ends of the conductive plate to fix the wires. The insulating base uses two interlocking shells. The insulating base is relatively large and typically has a track mounting groove in the middle of its bottom. An elastic element is installed in the track mounting groove, and a pair of locking feet are formed on the elastic element for fixing it to a support track. This design suffers from drawbacks such as complex track mounting structure and inconvenient assembly.

[0003] While existing technologies include designs where the locking foot is integrally molded onto the insulating base, these designs are typically used for smaller terminals. The outer retaining element of the locking foot is located at the edge of the insulating base, providing elastic deformation capability to ensure reliable holding of the mounting rail. However, for larger terminals, the locking foot's position is limited to the rail mounting groove in the middle of the bottom of the insulating base, making traditional integrally molded locking feet unsuitable. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology by providing a rail mounting structure for a terminal block, which is suitable for designs with rail mounting grooves and has the advantages of simple structure and reliable use.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A rail mounting structure for a terminal block includes an insulating base, characterized in that: the insulating base includes an integrally formed base body, the base body having a bottom for mounting a rail, a rail mounting groove recessed in the middle of the bottom, a pair of locking feet integrally formed on the bottom wall of the rail mounting groove, the locking feet including an inner elastic plate and an outer locking seat, the roots of the inner elastic plate and the outer locking seat being integrally formed with the bottom wall of the rail mounting groove, both having elastic deformation capability, a locking slot for inserting the rail being formed between the outer locking seat and the inner elastic plate, and a sliding groove for sliding the edge of the rail being inserted into the outer locking seat located on one side of the locking slot.

[0006] Preferably, the free end of the inner elastic plate is provided with a protruding rib that protrudes towards the outer plate. The outer plate is U-shaped, and the open end of the outer plate is fastened to the bottom wall of the track mounting groove. When the head of the outer plate is pushed, it achieves displacement through the deformation of the two connecting pieces of the outer plate.

[0007] Preferably, the distal connecting piece of the outer card holder is inclined outward from its head end to its root end.

[0008] Preferably, the free end of the inner elastic plate is formed with a raised edge that protrudes toward the side opposite to the raised rib.

[0009] By adopting the above technical solution, the locking foot is integrally molded on the insulating base, simplifying the structure and eliminating the need for assembly. Furthermore, the structural design of the locking foot ensures stable and reliable installation of the terminal block on the load-bearing rail. Specifically, both the inner elastic plate and the outer retainer are elastic, achieving a more reliable installation effect on the load-bearing rail. Further, the outer retainer is U-shaped, possessing both elastic deformation capability and strength to ensure reliable fixation to the load-bearing rail; simultaneously, the integral molding of the U-shaped outer retainer further enhances reliability.

[0010] The present invention will now be further described with reference to the accompanying drawings. Attached Figure Description

[0011] Figure 1 This is a perspective view of Embodiment 1 of the present utility model; Figure 2 This is a schematic diagram of the structure of Embodiment 1 of the present utility model; Figure 3 This is a structural schematic diagram of Embodiment 2 of the present invention. Detailed Implementation

[0012] See Figure 1 and Figure 2As shown, this utility model discloses a rail mounting structure for a terminal block, including an insulating base. The insulating base includes an integrally formed base body 1, which has a bottom 11 for supporting rail mounting. A rail mounting groove 111 is recessed in the middle of the bottom 11. A pair of locking feet 12 are integrally formed on the bottom wall of the rail mounting groove 111. The locking feet 12 include an inner elastic retaining plate 121 and an outer retaining seat 122. The roots of both the inner elastic retaining plate 121 and the outer retaining seat 122 are integrally formed with the bottom wall of the rail mounting groove 111, and both have elastic deformation capability. A locking slot 120 for inserting the support rail is formed between the inner elastic plate 122 and the inner elastic plate 121. The free end of the inner elastic plate 121 has a protruding rib 1211 protruding towards the outer mounting base 122. The outer mounting base 122 is U-shaped, and its open end engages with the bottom wall of the rail mounting groove 11. When pushed, the head of the outer mounting base 122 is displaced by the deformation of its two connecting pieces 1222 and 1223. The head of the outer mounting base 122 is recessed on one side of the locking slot 120 for sliding insertion of the edge of the support rail. Both the inner elastic plate and the outer mounting base are elastic, achieving a more reliable installation effect for the support rail. In addition to its elastic deformation capability, the outer mounting base also has strength, ensuring reliable fixation of the support rail. The outer mounting base 122 is U-shaped and hollow, which makes the integral injection molding of the outer mounting base 122 more stable and reliable.

[0013] like Figure 2 The diagram clearly shows that the distal connecting piece 1223 of the outer card holder 122 slopes outward from its head to its root. This provides a diagonal support effect on the outer side of the outer card holder, further reducing its deformation capacity and ensuring reliable fixation of the load-bearing rail. A raised edge 1212 is formed on the free end of the inner elastic card plate 121, protruding towards the side opposite to the raised rib 1211.

[0014] like Figure 3 Another embodiment shown differs from Embodiment 1 in that both the inner elastic plate 121 and the outer card seat 122 adopt a plate-like structure design. However, since the outer card seat 122 is a plate-like structure, it is difficult to coordinate the elastic deformation capability and strength because it is integrally injection molded on the base body 1. If it is too thin, the strength will be insufficient, making the installation unreliable. If it is too thick, the processing and molding will be difficult and it will be easy to deform.
