Description

Technical Field

[0001] The present application relates to the technical field of terminal blocks, and in particular to a leaf spring fixing structure of a terminal block. Background Art

[0002] Terminal blocks are a common connector component widely used in information-intensive fields such as industrial communications, industrial equipment, the power industry, and industrial control. Terminal blocks are used to connect two or more power, control, and / or data cables. For example, industrial control systems, such as power supplies, automatic power-off devices, and servo motor drives, often require dozens to hundreds of terminal blocks to accommodate frequent product changes. This allows for flexible scheduling, either automated or manual, to achieve efficient production of small batches and multiple specifications.

[0003] The leaf spring fixing structure of existing terminal blocks primarily consists of a metal conductive member and a leaf spring. The metal conductive member comprises two corresponding conductive plates, while the leaf spring is U-shaped, with multiple clamping tabs at the ends of its open side. Each clamping tab is secured to the ends of the conductive plates by clamping. However, when plugging into a plug terminal, the leaf spring is susceptible to movement within the conductive plates due to the pronounced vertical and horizontal stoppers, especially before the plug terminal is inserted. Furthermore, the leaf spring structure's large size when expanded results in a high level of waste during processing, resulting in high manufacturing and material costs.

[0004] In view of this, the applicant has focused on the shortcomings of the above-mentioned prior art and has conducted in-depth research and applied scientific theories to try his best to solve the above-mentioned problems, which has become the goal of the applicant's improvement.

[0047] See also Figures 1 to 9 As shown, the present application provides a leaf spring fixing structure for a terminal block, wherein the terminal block 8 is used in high current applications and primarily comprises an insulating housing 80 having a plurality of spaced-apart sockets 81. A leaf spring fixing structure 1 is disposed within each socket 81. The leaf spring fixing structure 1 primarily comprises a metal conductive member 10 and a pair of leaf springs 30, 30'.

[0048] Please see first Figures 2 to 5 As shown, the metal conductive member 10 mainly includes two corresponding conductive plates 11 and 11', wherein the structures of the two conductive plates 11 and 11' are roughly the same, and only the conductive plate 11 is described in detail. A pair of hanging parts 111 are provided at the upper and lower parts of the left side of each conductive plate 11, and a pair of buckles 113 are provided at the upper and lower parts of the right side of each conductive plate 11. Each leaf spring 30, 30' is fixed to each conductive plate 11, 11' respectively, wherein the structures of the two leaf springs 30, 30' are roughly the same, and only one leaf spring 30 is described in detail. One end of each leaf spring 30 is provided with a pair of hooks 31 fixed to each hanging part 111, and the other end of each leaf spring 30 is provided with a pair of grooves 33 fixed to each buckle 113.

[0049] In one embodiment, each conductive plate 11 primarily comprises a main plate 115, a connecting plate 117, and a bent plate 119. The main plates 115 are arranged face-to-face and spaced apart. The connecting plate 117 connects one end of each main plate 115, while the bent plate 119 is formed opposite the connecting plate 117 and connected to the other end of each main plate 115. The aforementioned hooks 111 are formed at the corners of the connecting plate 117 and the bent plates 119, respectively; and the aforementioned buckles 113 are formed on the outer side surfaces of the main plates 115. In this embodiment, the buckles 113 are buckle blocks, and the grooves 33 of the leaf springs 30 are buckle grooves that interlock with the buckle blocks. The hooks 111 and buckles 113 are used to secure the leaf springs 30, 30' in the front and rear directions.

[0050] Please also refer to Figure 6 and Figure 7As shown, in one embodiment, a first internal groove 1171 is defined at a corner end of the connecting plate 117 adjacent to the inner side of the main plate 115, and a second internal groove 1191 is defined at a corner end of the bent plate 119 adjacent to the inner side of the main plate 115. The second internal groove 1191 corresponds to the first internal groove 1171. A first elastic piece 35 is defined at the bottom of each leaf spring 30, and a second elastic piece 37 is defined at the top of each leaf spring 30. The first elastic piece 35 is embedded in the first internal groove 1171 and is clamped between the main plate 115 and the connecting plate 117; the second elastic piece 37 is embedded in the second internal groove 1191 and is clamped between the main plate 115 and the bent plate 119, thereby securing the leaf spring 30 in the upper, lower, and left, and right directions.

[0051] In one embodiment, the first elastic piece 35 and the second elastic piece 37 are both arc-shaped pieces.

[0052] In one embodiment, each leaf spring 30 further includes a plurality of conductive terminals 39 . The conductive terminals 39 are arranged at intervals and formed between the first elastic piece 35 and the second elastic piece 37 .

[0053] Please continue reading Figure 7 As shown, when the leaf spring 30 is assembled to the conductive plate 11 of the metal conductive member 10, each hook portion 31 is pushed into the gap between the connecting plate 117 and the bent plate 119. When each hook portion 31 passes through each hanging portion 111, it is hooked and fixed on the hanging portion 111 by the elastic restoring force of each hook portion 31. At the same time, the first elastic piece 35 and the second elastic piece 37 are pressed into the first embedded groove 1171 and the second embedded groove 1191 respectively; in addition, each groove portion 33 is in contact with each buckle portion 113 to achieve a buckled connection. This not only simplifies the assembly operation and makes it easy to judge whether it is assembled in place, but also makes the assembly more secure and the connection more reliable.

[0054] Please continue reading Figure 8 and Figure 9 As shown, when the plug terminal 9 is plugged into the socket 81 during use, the plug terminal 9 will simultaneously push the leaf springs 30, 30', and fix the front and rear directions of the leaf springs 30, 30' through the hanging parts 111 and the buckling parts 113. At the same time, the first embedded groove 1171 of the connecting plate 117, the second embedded groove 1191 of the bending plates 119, and the first elastic piece 35 and the second elastic piece 37 of the leaf spring 30 are embedded, matched and clamped, so that the leaf spring 30 can be fixed in the upper, lower, left and right directions, thereby achieving a six-direction positioning effect.
