Description

Technical Field

[0002] Terminal blocks are accessories used to achieve electrical connections; in the industrial field, they are classified as a type of connector. Most existing terminal blocks connect to wires by clamping the wire with screws. While this method provides a reliable electrical connection, it is relatively cumbersome, inconvenient, time-consuming, and labor-intensive during installation and removal.

[0003] A grounding-type side-entry terminal is disclosed in utility model publication number CN223109234U, including an insulating shell and a push block assembly, a grounding plate, a conductive sheet, and a spring sheet disposed within the insulating shell. Although the spring sheet and conductive sheet cooperate to achieve quick assembly and disassembly of the wire and terminal, it still has some drawbacks: the push block assembly has a complex structure and needs to be installed sequentially during installation. Although this solves the problem of tedious disassembly of the wire and terminal, it introduces the problem of tedious assembly and disassembly of the push block assembly; the spring sheet has a complex structure with many detailed features, which need to be processed separately during manufacturing, making the spring sheet manufacturing process complex and increasing the production cost of the terminal.

[0038] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0039] Example:

[0040] like Figures 1 to 8 As shown, this embodiment discloses a side-mounted terminal block structure, including an insulating housing 10, a pair of push blocks 11, and a conductive component 12 disposed within the insulating housing 10;

[0041] The conductive component 12 includes a conductive sheet 13 and a pair of spring sheets 14. The pair of spring sheets 14 are respectively disposed on both sides of the conductive sheet 13. The conductive sheet 13 is provided with a snap-fit ​​groove 15 on both sides. One end of the spring sheet 14 is fixedly provided with a T-shaped snap-fit ​​part 16, and the other end is fixedly provided with a contact part 17. The T-shaped snap-fit ​​parts 16 on the pair of spring sheets 14 are snapped into the pair of snap-fit ​​grooves 15 respectively. The contact parts 17 on the pair of spring sheets 14 are respectively in contact with both sides of the conductive sheet 13 to form an elastic pressing part 18. One end of the pair of spring sheets 14 with the contact part 17 is fixedly provided with a pair of contact arms 19 respectively. The pair of contact arms 19 are respectively located on both sides of the contact part 17.

[0042] A pair of push blocks 11 are slidably inserted into one side of the insulating housing 10 and are respectively configured to cooperate with a pair of spring pieces 14. One end of the push block 11 is provided with a U-shaped limiting groove 20. The contact portion 17 on one side of the conductive sheet 13 and the spring piece 14 is located in the U-shaped limiting groove 20 and is respectively in clearance fit with the U-shaped limiting groove 20. The end of the push block 11 with the U-shaped limiting groove 20 abuts against a pair of contact arms 19.

[0043] This invention features a pair of spring contacts 14 and a conductive sheet 13. Snap-fit ​​grooves 15 are provided on both sides of the conductive sheet 13, and a T-shaped snap-fit ​​portion 16, which mates with the snap-fit ​​grooves 15, is provided at one end of each spring contact 14. During installation, the T-shaped snap-fit ​​portions 16 at one end of each pair of spring contacts 14 are snapped into the snap-fit ​​grooves 15 to complete the assembly of the spring contacts 14 and the conductive sheet 13. A contact portion 17 is provided at the other end of each spring contact 14, forming an elastic crimp portion 18 that contacts one side of the conductive sheet 13. When installing a wire, the wire is simply passed through the elastic crimp portion 18, and the elasticity of the spring contact 14 secures the wire to the elastic crimp portion 18. Meanwhile, by setting a pair of push blocks 11 with U-shaped limiting grooves 20, both one side of the conductive sheet 13 and the contact portion 17 on the spring sheet 14 are wrapped within the U-shaped limiting grooves 20. Through clearance fitting, the deformation process of the spring sheet 14 during wire installation and removal remains within the U-shaped limiting grooves 20, thus preventing misalignment of the spring sheet 14 during wire installation and removal. This solves the problems of cumbersome wire installation and removal, complex installation and removal of the terminal push block 11 assembly, and increased production costs due to the high processing difficulty of the spring sheet 14 in current terminal blocks.

[0044] In order to facilitate a stable fit between the push block 11, the conductive sheet 13 and the contact portion 17 of the spring sheet 14, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a rectangular rib 21 is fixedly provided on one side of the push block 11, and the rectangular rib 21 is located on the outer side of one side wall of the U-shaped limiting groove 20.

[0045] As a further preferred embodiment, one end of the push block 11 is fixedly provided with an inner inclined platform 22, which is located inside the U-shaped limiting groove 20. The inner inclined platform 22 is located on the inner side of one side wall of the U-shaped limiting groove 20 and is located on the same side as the rectangular protruding rib 21.

[0046] As a further preferred embodiment, the push block 11 is provided with a rectangular rib 21 and an inner inclined platform 22, the side wall of which is inclined toward the inner inclined platform 22.

[0047] As a further preferred embodiment, the insulating housing 10 is provided with a pair of limiting slots 23 on one side, and a pair of push blocks 11 are respectively inserted into the pair of limiting slots 23 and slidably connected with the limiting slots 23.

[0048] As a further preferred embodiment, the insulating housing 10 is provided with a limiting groove 24 on one side, which is configured to cooperate with a pair of limiting slots 23. The rectangular protrusion 21 on the push block 11 is engaged in the limiting groove 24 and is slidably connected with the limiting groove 24.

[0049] As a further preferred embodiment, each of the pair of limiting slots 23 is fixedly provided with a trapezoidal protrusion 25, and one end of the push block 11 with a U-shaped limiting groove 20 passes through the trapezoidal protrusion 25 and slides in contact with the trapezoidal protrusion 25.

[0050] The lower end of the push block 11 is provided with a U-shaped limiting groove 20, so that the push block 11 has a concave shape, and the two side walls of the U-shaped limiting groove 20 form a pair of supporting leg structures.

[0051] A pair of limiting slots 23 are provided on the insulating housing 10, and a pair of push blocks 11 are inserted into the limiting slots 23 and slidably connected with the limiting slots 23, which facilitates the installation between the push blocks 11 and the insulating housing 10.

[0052] A rectangular rib 21 is provided on the exposed outer side of the support leg structure at the lower end of the push block 11. At the same time, a limiting groove 24 is provided on the insulating shell 10 to cooperate with a pair of limiting slots 23. In use, the rectangular rib 21 can be engaged in the limiting groove 24 and slidably connected with the limiting groove 24. The limiting groove 24 cooperates with the rectangular rib 21 to limit the maximum distance of the push block 11 to slide upward, thereby determining the initial state of the spring piece 14 and the conductive piece 13.

[0053] Meanwhile, an inner inclined platform 22 is provided at the inner end of the support leg structure with a rectangular rib 21. The contact part 17 between the conductive sheet 13 and the spring sheet 14 is located above the inner inclined platform 22. This allows the contact part 17 of the spring sheet 14 to move downward and contact the inner inclined platform 22 during the wiring process between the wire and the terminal. This, in turn, drives the push block 11 to move downward synchronously, ensuring that the U-shaped limiting groove 20 at the lower end of the push block 11 is always clamped on both sides of the spring sheet 14 and moves with the spring sheet 14. This prevents the elastic pressing part 18 between the spring sheet 14 and the conductive sheet 13 from disengaging from the U-shaped limiting groove 20 after wiring. This also prevents the two support leg structures at the lower end of the push block 11 from failing to accurately abut against the contact arm 19 on the spring sheet 14 when the wire is disassembled, thereby avoiding the risk of the support leg structure breaking.

[0054] The push block 11 has a support leg structure with a rectangular protrusion 21 and an inner inclined platform 22, which is inclined inward towards the inner inclined platform 22. At the same time, by setting a trapezoidal protrusion 25 in the limiting slot 23, one end of the push block 11 with a U-shaped limiting groove 20 passes through the trapezoidal protrusion 25. In use, the trapezoidal protrusion 25 can open the inclined support leg structure of the push block 11. The inclined support leg structure of the push block 11 can keep the push block 11 inward clamping force at all times, so that the push block 11 and the trapezoidal protrusion 25 are in close contact, preventing the support leg structure at the lower end of the push block 11 from deforming outward under force. It always ensures that the support leg structure is clamped on both sides of the contact part 17 of the conductive sheet 13 and the spring sheet 14 and does not flip outward, so that the contact part 17 of the conductive sheet 13 and the spring sheet 14 is not easy to detach from the U-shaped limiting groove 20.

[0055] To facilitate the installation of the conductive sheet 13 and the spring sheet 14, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that a conductive groove 26 is provided on one side of the insulating shell 10. The conductive groove 26 is connected to a pair of limiting slots 23 and a pair of limiting slide grooves 24. The conductive sheet 13 and a pair of spring sheets 14 are installed in the conductive groove 26. One end of the pair of push blocks 11 with U-shaped limiting grooves 20 extends into the conductive groove 26.

[0056] As a further preferred embodiment, the conductive groove 26 is fixedly provided with a plurality of limiting ribs 27 respectively configured to cooperate with the conductive sheet 13 and the pair of spring sheets 14, and the plurality of limiting ribs 27 are used to restrict the conductive sheet 13 and the pair of spring sheets 14 within the conductive groove 26.

[0057] The conductive groove 26 communicates with a pair of limiting slots 23 and a pair of limiting slides 24, which facilitates a stable fit between the push block 11, the conductive sheet 13, and the contact portion 17 of the spring sheet 14. The setting of several limiting ribs 27 can help limit the installation position of the conductive sheet 13 and the spring sheet 14, and at the same time improve the accuracy of the installation of the conductive sheet 13 and the spring sheet 14.

[0058] To facilitate the connection and grounding of wires, this embodiment is an improvement on the above embodiment. The difference from the above embodiment is that the insulating housing 10 is provided with a pair of wiring slots 28, which are located on both sides of the insulating housing 10. The wiring slots 28 are correspondingly arranged with the elastic crimping part 18 and are connected to the conductive slot 26. A grounding plug 29 is provided on one side of the insulating housing 10. The grounding plug 29 is inserted into one side of the insulating housing 10, and one end of the grounding plug 29 extends into the conductive slot 26 and is inserted into the conductive piece 13.

[0059] The wiring slot 28 is configured to cooperate with the elastic crimping part 18. During wiring, the wire can be passed through the wiring slot 28 and the elastic crimping part 18. The spring piece 14 is deformed downward by the wire, and the wire is fixed in the elastic crimping part 18 by the elastic force generated by the spring piece 14. The grounding plug 29 facilitates grounding.

[0060] Working principle of this utility model:

[0061] This invention features a pair of spring contacts 14 and a conductive sheet 13. Snap-fit ​​grooves 15 are provided on both sides of the conductive sheet 13, and a T-shaped snap-fit ​​portion 16, which mates with the snap-fit ​​grooves 15, is provided at one end of each spring contact 14. During installation, the T-shaped snap-fit ​​portions 16 at one end of each pair of spring contacts 14 are snapped into the snap-fit ​​grooves 15 to complete the assembly of the spring contacts 14 and the conductive sheet 13. A contact portion 17 is provided at the other end of each spring contact 14, forming an elastic crimp portion 18 that contacts one side of the conductive sheet 13. When installing a wire, the wire is simply passed through the elastic crimp portion 18, and the elasticity of the spring contact 14 secures the wire to the elastic crimp portion 18. Meanwhile, by setting a pair of push blocks 11 with U-shaped limiting grooves 20, the contact portion 17 on one side of the conductive sheet 13 and the spring sheet 14 are both wrapped in the U-shaped limiting grooves 20. Through clearance fit, the spring sheet 14 is always within the U-shaped limiting grooves 20 during the wire loading and unloading process, thereby avoiding misalignment of the spring sheet 14 when the wire is installed or removed.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the present invention.
