DETAILED DESCRIPTION

[0037] The following is combined with Figure 1-5 This application is described in further detail.

[0038] An embodiment of the present application discloses a track-type wiring terminal.

[0039] Reference Figure 1 and Figure 2The terminal block includes a mounting base 1 and a wiring base 2. The mounting base 1 includes a mounting body 11, a mounting sub-body 12 and a connecting bolt 13. The mounting body 11 is located below the wiring base 2. First limiting grooves 111 are provided on both sides of one end of the mounting body 11, and guide grooves 112 are provided on both sides of the mounting body 11. The guide grooves 112 include a vertical portion 112a and an inclined portion 112b. The vertical portion 112a is arranged along the vertical direction, and the inclined portion 112b is connected to the lower end of the vertical portion 112a and is inclined toward a side away from the first limiting groove 111.

[0040] The mounting sub-body 12 is movably arranged in the mounting main body 11. The mounting sub-body 12 is protruded on both sides of one end away from the first limiting groove 111 to form hooks 121. The two sides of the mounting sub-body 12 corresponding to the guide groove 112 are protruded to form guide protrusions 122, so that each guide protrusion 122 is limited in each guide groove 112, that is, the guide protrusion 122 is located in the vertical portion 112a or the inclined portion 112b. The connecting bolt 13 is vertically arranged, and the lower end of the connecting bolt 13 is movably arranged in the wiring seat 2 and the mounting main body 11 in turn and is threadedly connected to the mounting sub-body 12. The upper end of the connecting bolt 13 protrudes from the wiring seat 2 to facilitate the rotation of the connecting bolt 13.

[0041] In actual application, the staff first places the installation body 11 in the guide rail and adjusts the position of the installation body 11 so that one side of the guide rail is limited in the two first limit grooves 111, and the other side of the guide rail is located in the two hooks 121, and then presses the terminal block 2 and rotates the connecting bolt 13, so that the connecting bolt 13 moves downward and the installation sub-body 12 moves upward. In this process, the guide protrusion 122 moves from the inclined portion 112b to the vertical portion 112a, so that the installation sub-body 12 is elastically deformed, so that the hook 121 moves upward and inward (that is, toward the side close to the first limit groove 111), so that the hook 121 is clamped on the guide rail to achieve the installation between the installation seat 1 and the guide rail. It should be noted that the connecting bolt 13 abuts against the upper side of the terminal block 2 so that the terminal block 2 is limited between the connecting bolt 13 and the installation body 11 to limit the movement or rotation of the terminal block 2.

[0042] After the guide rail is installed on the electrical equipment, the staff can install and remove the mounting base 1 by rotating the connecting bolt 13 so that the hook 121 is clamped on the guide rail or the clamping of the guide rail is released. Therefore, there is no need to remove the guide rail from the electrical equipment, thereby facilitating the installation and removal of the terminal block on the installed guide rail. At the same time, the mounting base 1 can also be installed on guide rails of different sizes to improve the applicability of the terminal block.

[0043] In some embodiments, snap-in grooves 113 are provided on both sides of the installation body 11 near one end of the first limiting groove 111, and the two snap-in grooves 113 are respectively connected to the two first limiting grooves 111 for one side of the guide rail to be inserted and snap-in, that is, the guide rail is limited in the first limiting groove 111 and then snap-into the snap-in groove 113 to limit the deviation of the guide rail and improve the installation stability between the mounting seat 1 and the guide rail.

[0044] In some embodiments, the second limiting grooves 114 are provided on both sides of the end of the installation body 11 away from the first limiting groove 111, and the side of the guide rail away from the first limiting groove 111 is limited in the second limiting groove 114. It should be noted that the maximum distance between the first limiting groove 111 and the second limiting groove 114 is greater than the width of the guide rail. The second limiting groove 114 cooperates with the first limiting groove 111 to further limit the deviation of the guide rail, so as to accurately clamp the hook 121 to the guide rail, so as to improve the installation accuracy between the mounting seat 1 and the guide rail, and facilitate the installation between the mounting seat 1 and the guide rail.

[0045] In some embodiments, the guide protrusion 122 is arranged in a hemispherical shape to guide the movement of the guide protrusion 122 between the inclined portion 112b and the vertical portion 112a, thereby facilitating the movement of the guide protrusion 122 from the inclined portion 112b to the vertical portion 112a, or from the vertical portion 112a to the inclined portion 112b, thereby facilitating the installation and disassembly of the mounting base 1.

[0046] In some embodiments, two limiting protrusions 123 are protruded from the upper side of the mounting sub-body 12, and the two limiting protrusions 123 are respectively located on both sides of the connecting bolt 13. When the guide protrusion 122 is located at the upper end of the vertical portion 112a, the limiting protrusion 123 abuts against the mounting main body 11, which can limit the guide protrusion 122 from being separated from the vertical portion 112a.

[0047] Reference Figure 3 In some embodiments, the terminal block 2 includes a base 21, two clamping pieces 22 and two adjusting bolts 23. The two clamping pieces 22 are movably arranged at the two ends of the base 21, and a wiring groove 24 is formed between each clamping piece 22 and the base 21. The two adjusting bolts 23 are threadedly connected to the upper side of the base 21, and the lower end of each adjusting bolt 23 is connected to each clamping piece 22. The clamping piece 22 is raised or lowered by rotating the adjusting bolt 23. In practical applications, one end of the cable is placed in the wiring groove 24, and the clamping piece 22 is lowered by rotating the adjusting bolt 23, so that the cable is clamped between the clamping piece 22 and the base 21 to achieve the fixation of the cable. The structure is simple and the operation is convenient. In addition, cables of different sizes can also be fixed, further improving the applicability of the terminal block.

[0048] Reference Figure 4In some embodiments, a through hole 221 is opened on the upper side of the clamping plate 22, and the lower end of the adjusting bolt 23 is penetrated through the through hole 221 and is set with an enlarged diameter, that is, the diameter of the lower end of the adjusting bolt 23 is larger than the diameter of the through hole 221, so that the clamping plate 22 overlaps the adjusting bolt 23 under the action of gravity, thereby realizing the connection between the adjusting bolt 23 and the clamping plate 22.

[0049] In some embodiments, a clearance groove 222 is opened on the upper side of the clamping plate 22, and the clearance groove 222 is connected to the through hole 221 and extends to one side of the clamping plate 22, so that the clamping plate 22 can be inserted into the adjusting bolt 23 through the clearance groove 222, thereby facilitating the installation and disassembly between the adjusting bolt 23 and the clamping plate 22.

[0050] Reference Figure 5 In some embodiments, the terminal block further includes a protective shell 3, which is disposed on both sides of the mounting base 1 and the wiring base 2, and can reduce the contact between the mounting base 1 and the wiring base 2 and dust, so as to protect the mounting base 1 and the wiring base 2.

[0051] In some embodiments, the protective shell 3 includes a first shell 31 and a second shell 32. The first shell 31 and the second shell 32 are detachably connected. The detachable method may be but is not limited to bolt connection, snap connection, plug-in connection, etc., as long as a stable connection between the first shell 31 and the second shell 32 can be achieved, so as to facilitate the installation of the protective shell 3 on the mounting seat 1 and the terminal block 2.

[0052] The implementation principle of this embodiment is as follows: in actual application, the staff first places the installation body 11 in the guide rail and adjusts the position of the installation body 11 so that one side of the guide rail is clamped and limited in the two first limiting grooves 111, and the other side of the guide rail is located in the two hooks 121, and then presses the wiring seat 2 and rotates the connecting bolt 13, so that the connecting bolt 13 moves downward and the installation sub-body 12 moves upward. In this process, the guide protrusion 122 moves from the inclined portion 112b to the vertical portion 112a, so that the installation sub-body 12 is elastically deformed, so that the hook 121 moves upward and inward (that is, toward the side close to the first limiting groove 111), so that the hook 121 is clamped on the guide rail to achieve the installation between the installation seat 1 and the guide rail. It should be noted that the connecting bolt 13 abuts against the upper side of the wiring seat 2 so that the wiring seat 2 is limited between the connecting bolt 13 and the installation body 11 to limit the movement or rotation of the wiring seat 2.

[0053] After the guide rail is installed on the electrical equipment, the staff can install and remove the mounting base 1 by rotating the connecting bolt 13 so that the hook 121 is clamped on the guide rail or the clamping of the guide rail is released. Therefore, there is no need to remove the guide rail from the electrical equipment, thereby facilitating the installation and removal of the terminal block on the installed guide rail. At the same time, the mounting base 1 can also be installed on guide rails of different sizes to improve the applicability of the terminal block.

[0054] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
