Description

Technical Field

[0001] The present application relates to the technical field of circuit connection, and in particular to a terminal block. Background Art

[0002] Terminal blocks are insulating components that carry multiple or multiple groups of mutually insulated terminal components and are used to fix supporting parts. The function of terminal blocks is to connect the lines of devices inside the screen and devices outside the screen, and play the role of signal (current and voltage) transmission. With terminal blocks, wiring is beautiful and maintenance is convenient. When connecting long-distance lines, it is mainly reliable, and construction and maintenance are convenient.

[0003] In order to facilitate assembly, the existing terminal block has a larger gap between the base and the conductive sheet. After the conductive sheet is installed in the base, the conductive sheet is clamped in the base with the bolts and nuts connected to the terminal. When the bolts and nuts are installed in place, the conductive sheet can be stably set in the base. However, after the terminal block is installed in the electrical equipment, when installing the connecting wire on the terminal block, it is necessary to remove the bolts stuck in the base and then install the terminal. In the absence of bolts to fix the terminal block, the existing terminal block only sets an angle between the two conductive sheets, so that the conductive sheet and the base are fixed by friction. However, due to the large gap between the base and the conductive sheet, the conductive sheet often falls off from the terminal block base, and it is necessary to manually install the conductive sheet into the terminal block base and then install the power cord. Such operation is very cumbersome, time-consuming and labor-intensive, and the assembly efficiency is low.

[0004] Therefore, the connection stability between the conductive sheet on the terminal block and the base needs to be further improved. Utility Model Content

[0034] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of them. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of this application.

In addition, the terms "first" and "second" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance or indicating the number of technical features indicated. Thus, the features defined as "first" and "second" may explicitly or implicitly include one or more features. In the description of the present application, "multiple" means two or more, unless otherwise clearly and specifically defined.

[0036] In this application, the word "exemplary" is used to mean "serving as an example, illustration, or description." Any embodiment described in this application as exemplary is not necessarily to be construed as being preferred or advantageous over other embodiments. The following description is given to enable any technician in the field to implement and use the present application. In the following description, details are listed for the purpose of explanation. It should be understood that a person of ordinary skill in the art can recognize that the present application can be implemented without using these specific details. In other instances, known structures and processes will not be elaborated in detail to avoid obscuring the description of the present application with unnecessary details. Therefore, the present application is not intended to be limited to the embodiments shown, but is consistent with the widest scope consistent with the principles disclosed in the present application.

[0037] To facilitate understanding of the scheme of the present application, the spline curves and arrows used in the drawings are explained here: the components indicated by the spline curves without arrows are solid components, that is, components with solid structures; the components indicated by the spline curves with arrows are virtual components, that is, components without solid structures.

[0038] See also Figure 1 and Figure 2 The embodiment of the present application provides a terminal block 1, including: a base 10, the base 10 includes a first beam 11 and a second beam 12 arranged at intervals, a gap portion 13 is provided between the first beam 11 and the second beam 12, and the first beam 11 has a first limiting portion 111.

[0039] The terminal block 1 further includes a conductive sheet 20 . The conductive sheet 20 is inserted into the gap 13 . The conductive sheet 20 has a second limiting portion 231 . The first limiting portion 111 and the second limiting portion 231 are engaged with each other.

[0040] The terminal block 1 provided in the present application can stably fix the conductive sheet 20 on the base 10 by clamping the first limiting portion 111 of the first beam 11 and the limiting portion of the conductive sheet 20, thereby preventing the conductive sheet 20 from falling off and improving assembly efficiency.

[0041] In some embodiments, the first limiting portion 111 is a groove with an opening toward the conductive sheet 20, and the second limiting portion 231 is a protrusion toward the first beam 11, and the protrusion is embedded in the groove. By embedding the protrusion into the groove, the conductive sheet 20 can be stably fixed on the base 10 to prevent the conductive sheet 20 from falling off.

[0042] Furthermore, in some embodiments, the depth of the groove is greater than the height of the protrusion, so that the protrusion can be completely embedded in the groove, so that the conductive sheet 20 and the base 10 are stably connected.

[0043] In some embodiments, the conductive sheet 20 has multiple layers of conductive sub-sheets 21 .

[0044] Furthermore, the multiple layers of conductive sub-sheets 21 are sequentially arranged along the width direction of the gap 13 , and the second limiting portion 231 is located on the conductive sub-sheet 21 closest to the first beam 11 .

[0045] It should be noted that the width direction of the gap portion 13 is the direction from the first beam 11 to the second beam 12 .

[0046] Exemplarily, the conductive sheet 20 has two layers of conductive sub-sheets 21, including a first conductive sub-sheet 211 close to the first beam 11 and a second conductive sub-sheet 212 close to the second beam 12, wherein the second position limiting portion 231 is located on the first conductive sub-sheet 211. When the second position limiting portion 231 is a protrusion, the second position limiting portion 231 does not need to be provided on the second conductive sub-sheet 212.

[0047] In some embodiments, see Figure 2 and Figure 3 The conductive sub-sheet 21 includes a connecting sheet portion 23 and a fixing sheet portion 22 which are connected to each other. The connecting sheet portion 23 is located in the gap portion 13 , and the fixing sheet portion 22 is located outside the gap portion 13 .

[0048] Furthermore, the fixed sheet portions 22 of the multi-layer conductive sub-sheets 21 are stacked in sequence along the width direction of the gap portion 13 and fit each other. The connecting sheet portions 23 of the multi-layer conductive sub-sheets 21 are arranged at intervals. In other words, there is an angle greater than 0° between two adjacent layers of conductive sub-sheets 21. It can be understood that the second limiting portion 231 is located on the connecting sheet portion 23 closest to the first beam 11. The conductive sub-sheet 21 close to the second beam 12 can be fitted with the second beam 12, and the conductive sub-sheet 21 close to the first beam 11 can be clamped with the first beam 11, so as to achieve a stable connection between the conductive sheet 20 and the base 10.

[0049] It should be noted that the connection sheet parts 23 of the multi-layer conductive sub-sheets 21 are elastically connected. In other words, the angle between the connection sheet parts 23 can be adjusted by pressing, such as pressing to make the connection sheet parts 23 of the multi-layer conductive sub-sheets 21 fit together, but in a natural state without external force, the two adjacent layers of conductive sub-sheets 21 are always spaced apart. By pressing, the conductive sheet 20 can pass through the gap part 13, the second conductive sub-sheet 212 fits with the second crossbeam 12, and the second limit part 231 corresponds to the first limit part 111. After stopping pressing, the first conductive sub-sheet 211 recovers its deformation through elasticity, so that the second limit part 231 is clamped with the first limit part 111.

[0050] In some embodiments, when the second limiting portion 231 is a protrusion, the sum of the thickness of the multi-layer conductive sub-sheet 21 and the thickness of the protrusion is less than the width h3 of the gap 13. In this way, when the conductive sheet 20 is installed on the base 10, it is beneficial for the conductive sheet 20 to completely pass through the gap 13. It should be noted that the thickness of the multi-layer conductive sub-sheet 21 is the sum of the thickness of each conductive sub-sheet 21, not the distance from the top conductive sub-sheet 21 to the bottom conductive sub-sheet 21 in the natural state of the conductive sheet 20.

[0051] In some embodiments, when the second limiting portion 231 is a protrusion, the distance from the vertex of the protrusion to the conductive sheet 20 farthest from the protrusion in the natural state of the conductive sheet 20 is greater than the width of the gap 13. In this way, the conductive sheet 20 passes through the gap 13, and the conductive sub-sheet 21 closest to the first beam 11 recovers its deformation through elasticity, so that the protrusion can be embedded in the groove, thereby achieving a stable connection between the conductive sheet 20 and the base 10.

[0052] In some embodiments, the conductive sheet 20 further includes a terminal sheet portion 24 located outside the gap portion 13 . The terminal sheet portion 24 and the fixing sheet portion 22 are respectively located on both sides of the first beam 11 . The connecting sheet portion 23 connects the terminal sheet portion 24 and the fixing sheet portion 22 .

[0053] Furthermore, the terminal tabs 24 and the connecting tabs 23 are arranged obliquely, and the terminal tabs 24 of the multi-layer conductive sub-sheets 21 are arranged at intervals. Specifically, the terminal tabs 24 of the multi-layer conductive sub-sheets 21 are arranged in parallel.

[0054] In some embodiments, a self-locking hole 241 is provided at the end of the wiring piece 24. Through the self-locking hole 241, a stable connection between the external wiring harness and the terminal block 1 can be achieved.

[0055] In some embodiments, see Figure 4, the slope i1 on the side of the second limiting portion 231 close to the fixed sheet portion 22 is less than 0.3. It should be noted that the slope is generally also called the slope ratio, which represents the ratio of the vertical height and horizontal width of the slope surface, such as h1 is the vertical distance between the apex of the protrusion and the bottom of the protrusion along the direction close to the fixed sheet portion 22, l1 is the horizontal distance between the apex of the protrusion and the bottom of the protrusion along the direction close to the fixed sheet portion 22, i1 = h1 / l1. In this way, a relatively gentle slope is formed on the side of the second limiting portion 231 close to the fixed sheet portion 22, which facilitates pushing the conductive sheet 20 into the gap portion 13 of the base 10, so that the second limiting portion 231 is engaged with the first limiting portion 111.

[0056] In some embodiments, see Figure 5 , the slope i2 of the side of the second limiting portion 231 close to the wiring piece 24 is greater than 1. h2 is the vertical distance between the vertex of the protrusion and the bottom of the protrusion along the direction close to the wiring piece 24, l2 is the horizontal distance between the vertex of the protrusion and the bottom of the protrusion along the direction close to the wiring piece 24, i2 = h2 / l2. A relatively steep slope is formed on the side of the second limiting portion 231 close to the wiring piece 24. After the conductive sheet 20 is pushed into the gap 13 of the base 10, the side of the second limiting portion 231 close to the wiring piece 24 can be more reliably engaged with the first limiting portion 111 of the first beam 11, so that the first limiting portion 111 and the second limiting portion 231 form a reliable limit, thereby avoiding the conductive sheet 20 from accidentally falling off from the gap 13 of the base 10. When the conductive sheet 20 needs to be removed from the base 10 , the conductive sheet 20 cannot be directly removed. Instead, the conductive sheet 21 closest to the first beam 11 needs to be pressed down so that the height of the second limiting portion 231 is lower than the first beam 11 . Only then can the conductive sheet 20 be removed from the base 10 .

[0057] In some embodiments, when the first limiting portion 111 is a groove and the second limiting portion 231 is a protrusion, the distance from the protrusion to the connecting piece 24 is greater than the groove wall width of the groove. It can be understood that the connecting piece 24 and the connecting piece 23 are arranged obliquely. If the distance from the protrusion to the connecting piece 24 is too small, the protrusion may abut against the bottom of the first beam 11 and cannot be embedded in the groove. The protrusion is located in the groove and can abut against the inner wall of the groove, thereby improving the stability of the connection between the conductive sheet 20 and the base 10.

[0058] In some embodiments, see Figure 6 The base 10 includes a partition wall 30 , which is intersected with the first beam 11 . The terminal row 1 includes a plurality of conductive sheets 20 , which are spaced apart in sequence, and the partition wall 30 is disposed between two adjacent conductive sheets 20 .

[0059] In some embodiments, the second cross beam 12 is provided with a mounting groove 121, the fixing plate 22 is provided with a mounting hole, and the mounting groove 121 and the mounting hole are correspondingly connected. When the wiring terminal 40 is connected to the base 10, the wiring terminal 40 can be fixed to the base 10 by bolts and nuts, and pass through the mounting groove 121 and the mounting hole in sequence.

[0060] In some embodiments, the second limiting portion 231 is integrally formed with the conductive sheet 20. Specifically, when the second limiting portion 231 is a protrusion, in the process of preparing the conductive sheet 20, a flat triangular prism or streamlined column can be set in the stamping die of the conductive sheet 20, and the conductive sub-sheet 21 is stamped below the conductive sub-sheet 21 where the second limiting portion 231 is required, so as to form a protrusion above the conductive sheet 20. The protrusion is integrally formed with the conductive sheet 20, which can save the cumbersome process of separately setting the limiting portion, and the conductive sheet 20 and the protrusion are integrated, which is conducive to improving the connection stability between the conductive sheet 20 and the base 10.

[0061] When the terminal row 1 provided by the present application is used, when the conductive sheet 20 is assembled with the base 10, the first conductive sub-sheet 211 and the second conductive sub-sheet 212 are pressed together, and the fixed sheet portion 22 of the conductive sheet 20 is extended into the gap portion 13. Since the slope from the protrusion to the wiring sheet portion 24 is small, the conductive sheet 20 can be easily pushed into the base 10. When the pressing stops, the first conductive sub-sheet 211 rebounds due to elasticity, and the protrusion is engaged with the groove. The conductive sheet 20 is installed in place on the base 10. Since the slope from the protrusion to the fixed sheet portion 22 is large, the conductive sheet 20 cannot be easily pulled out of the base 10. It is necessary to use external force to press the wiring sheet portion 24 of the conductive sheet 20 so that the height of the protrusion is lower than the bottom of the first beam 11, and then the conductive sheet 20 can be pulled out of the base 10. In the terminal row 1 provided by the present application, the conductive sheet 20 and the base 10 can be stably connected to prevent the conductive sheet 20 from falling off.
