Abstract

A terminal block with a buffering structure includes an insulating base, a turning assembly, a buffering structure and a clamping spring. The insulating base includes a body and a side cover plate. The body has a receiving groove and an operating opening. The receiving groove and the operating opening are located at different sides of the body and are in communication with each other. The side cover plate is arranged on the body and covers the receiving groove. The turning assembly is rotatably arranged between the body and the side cover plate between a clamping position and a releasing position. The buffering structure is arranged on the insulating base or the turning assembly. The clamping spring is arranged in the receiving groove and elastically abuts against the turning assembly. When the turning assembly is pushed by an external force, the turning assembly is rotated from the clamping position to the releasing position. When the external force is removed from the turning assembly, the clamping spring pushes the turning assembly to rotate reversely. Thus, the buffering structure interferes with the insulating base or the turning assembly to form a buffer. Therefore, the turning assembly can be reset to slow down and avoid damage.

Description

Technical Field

[0001] This utility model relates to a terminal block, and more particularly to a terminal block with a buffer structure that allows the turn-on assembly to buffer deceleration during reset. Background Technology

[0002] Terminal blocks are widely used in machinery, industrial control equipment, and electrical appliances. They are primarily electrical conductive devices used to provide electrical connections for wires. A typical terminal block consists of a housing, a handle, and a spring clip. The spring clip is installed inside the housing to secure the wire. The user can push the spring clip by operating the handle to release the wire, and then the spring clip's own elasticity will return the handle to its original position and clamp the wire.

[0003] However, in order to securely clamp the wire, the spring clips are mostly designed to have a large elastic force. While this ensures that the wire is firmly clamped, it can also cause excessive force when the handle resets, resulting in direct impact with the housing and damage or malfunction of the terminal block. Therefore, designing a terminal block that can buffer and decelerate when the handle resets is an urgent shortcoming that needs to be addressed.

[0004] In view of this, the creator has devoted himself to researching and applying theoretical principles to address the shortcomings of the existing technology, and has made every effort to solve the above-mentioned problems, which has become the creator's goal for improvement. Utility Model Content

[0005] The main purpose of this invention is to enable the rotating assembly to achieve a buffering and deceleration effect when resetting, thereby preventing the terminal block structure from being damaged or malfunctioning due to strong impact.

[0006] To achieve the above objectives, this utility model provides a terminal block with a buffer structure, including an insulating base, a turning assembly, a buffer structure, and a clamping spring. The insulating base includes a body and a side cover plate. The body has a receiving groove and an operating port. The receiving groove is formed by recessing from one side of the body. The operating port is located on the other side of the body and communicates with the receiving groove. The side cover plate is disposed on the body and covers the receiving groove. The turning assembly is rotatably disposed between the body and the side cover plate between a clamping position and a releasing position. The buffer structure is disposed on at least one of the insulating base and the turning assembly. The clamping spring is disposed in the receiving groove and elastically abuts against the turning assembly. When the turning assembly is pushed by an external force, the turning assembly rotates from the clamping position to the releasing position along a rotation direction. When the external force is released from the turning assembly, the clamping spring pushes the turning assembly to rotate in the opposite direction along the rotation direction, thereby causing the buffer structure to interfere with the other of the insulating base and the turning assembly to form a buffer.

[0007] In one embodiment of the present invention, the buffer structure includes a pair of arc-shaped protrusions, each arc-shaped protrusion extending gradually in the opposite direction to the rotation direction.

[0008] In one embodiment of the present invention, each arc-shaped protrusion is respectively disposed on the opposite sides of the turning assembly facing the body and the side cover plate. When the turning assembly is in the clamping position, the side of each arc-shaped protrusion facing the body and the side facing the side cover plate are completely abutted against the body and the side cover plate respectively. When the turning assembly is in the release position, each arc-shaped protrusion is completely detached from the body and the side cover plate.

[0009] In one embodiment of the present invention, each arc-shaped protrusion is respectively disposed on the side of the body facing the turning assembly and the side of the side cover plate facing the turning assembly. When the turning assembly is in the clamping position, each arc-shaped protrusion completely abuts against the opposite sides of the turning assembly facing the body and the side cover plate. When the turning assembly is in the release position, each arc-shaped protrusion completely disengages from the turning assembly.

[0010] In one embodiment of the present invention, the buffer structure includes several protrusions, each protrusion being disposed on the side of the turning assembly facing the side cover plate.

[0011] In one embodiment of the present invention, the buffer structure includes a plurality of protrusions, a portion of which is disposed on the side of the turning assembly facing the side cover plate, and the remaining portions of which are disposed on the side of the side cover plate facing the turning assembly and are configured corresponding to the positions of the protrusions disposed on the turning assembly.

[0012] In one embodiment of the present invention, the buffer structure includes several protrusions, each protrusion being disposed on the side of the side cover plate facing the turning assembly.

[0013] In one embodiment of the present invention, the buffer structure further includes several grooves, each groove being formed on the side of the turning assembly facing the side cover plate and corresponding to the position of each protrusion on the side cover plate. When the turning assembly is in the clamping position, each protrusion is engaged in the groove.

[0014] In one embodiment of the present invention, the buffer structure includes a plurality of protrusions. A portion of the plurality of protrusions is disposed on the side of the rotating assembly facing the side cover plate. Another portion of the plurality of protrusions is disposed on the side of the side cover plate facing the rotating assembly and is configured corresponding to the position of each protrusion disposed on the rotating assembly. The remaining portion of the plurality of protrusions is disposed on the side of the body away from the rotating assembly and is configured corresponding to the position of each protrusion disposed on the rotating assembly.

[0015] In one embodiment of this utility model, the buffer structure is configured adjacent to the operating port.

[0016] The terminal block with a buffer structure of this utility model, by setting the buffer structure in at least one of the insulating base and the turning assembly, so that when the external force disengages from the turning assembly and causes the clamping spring to push the turning assembly to reverse and reset, the buffer structure can gradually generate frictional interference with the other one of the insulating base and the turning assembly during the reset process of the turning assembly, thereby playing a buffering and deceleration effect, so as to avoid damage or failure of the terminal block structure due to the strong impact of the turning assembly.

[0063] The detailed description and technical content of this utility model will be explained in conjunction with the accompanying drawings. However, the accompanying drawings are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0064] This utility model provides a terminal block with a buffer structure, which allows a wire (not shown in the figure) to be inserted and connected. Please refer to [the following text is missing from the original] first. Figure 1 and Figure 2 As shown, this is the first embodiment of the terminal block with a buffer structure of the present invention, which mainly includes an insulating base 10, a turning assembly 20, a buffer structure 30 and a clamping spring 40.

[0065] The insulating base 10 includes a body 11 and a side cover 12. The body 11 has a receiving groove 111, an operating port 112, and a wire insertion hole 113. The receiving groove 111 is recessed inward from one side of the body 11. Specifically, the body 11 also has a first side surface 114 and a second side surface 115 arranged opposite to each other. The receiving groove 111 is recessed inward from the first side surface 114, and the operating port 112 and the wire insertion hole 113 are located on the remaining side between the first side surface 114 and the second side surface 115 and are respectively connected to the receiving groove 111. The wire insertion hole 113 is for inserting the wire from the outside of the insulating base 10 into the receiving groove 111 of the body 11. In this embodiment, the receiving groove 111 is recessed inward from the first side surface 114 (i.e., the right side surface) of the body 11, the operating port 112 is located on the top surface of the body 11, and the wire insertion hole 113 is located on the front side surface of the body 11, but the present invention is not limited thereto. For example, the receiving groove 111 can also be formed by inward recessing from the second side surface 115 (i.e., the left side) of the body 11. The operating port 112 and the insertion hole 113 can be located simultaneously on the top surface, front side surface, rear side surface of the body 11, or respectively on opposite sides of the body 11, depending on the needs of use and design. The side cover plate 12 is disposed on the body 11 and covers the receiving groove 111. Specifically, in this embodiment, the side cover plate 12 is disposed on the first side surface 114 (i.e., the right side) of the body 11 and covers the receiving groove 111. The side cover plate 12 and the body 11 can be combined and fixed by means of fitting, snapping, fastening, locking, fastening, bonding or welding, etc., and this utility model does not impose many limitations on this.

[0066] The toggle assembly 20 is rotatably disposed between the body 11 and the side cover plate 12 of the insulating base 10. Specifically, the toggle assembly 20 can rotate between a clamping position P1 and a releasing position P2. The toggle assembly 20 has a pivot portion 21 and a lever 22. The pivot portion 21 is pivotally connected within a groove 111 of the body 11, thereby allowing the toggle assembly 20 to rotate relative to the insulating base 10. The lever 22 extends from the pivot portion 21 and protrudes into the operating port 112 for the user to operate the toggle assembly 20.

[0067] The buffer structure 30 is disposed on at least one of the insulating base 10 and the turning assembly 20. In this embodiment, the buffer structure 30 is disposed on the turning assembly 20, and the buffer structure 30 includes a pair of arc-shaped protrusions 31 respectively disposed on opposite sides of the turning assembly 20 (i.e., the side of the turning assembly 20 facing the body 11 and the side of the turning assembly 20 facing the side cover plate 12). However, this utility model is not limited thereto, and other embodiments will be described below. In this embodiment, the buffer structure 30 is configured adjacent to the operating port 112 of the body 11, thereby achieving a good buffering effect. However, this utility model is not limited thereto.

[0068] The clamping spring 40 is disposed within the receiving groove 111 of the body 11, and the clamping spring 40 elastically abuts against the turning assembly 20. The clamping spring 40 is used to pre-press and fix the turning assembly 20 in the clamping position P1, thereby clamping and fixing the wire inserted from the insertion hole 113 within the receiving groove 111. Specifically, the clamping spring 40 can apply its own elastic force to the turning assembly 20, thereby fixing the turning assembly 20 in the clamping position P1 without external force, thus clamping and fixing the wire.

[0069] More specifically, please see Figure 3 and Figure 4 As shown. When the lever 22 of the toggle assembly 20 is pushed by the user with an external force greater than the elastic force of the clamping spring 40, the toggle assembly 20 will rotate from the clamping position P1 to the release position P2 via its pivot 21. At this time, the clamping spring 40 will release the wire so that the user can pull it out of the plug hole 113 to the outside of the body 11, or the user can insert the wire from the plug hole 113 into the receiving groove 111 inside the body 11. At this time, the buffer structure 30 of the toggle assembly 20 is completely detached from the insulating base 10 (in this embodiment, each arc-shaped protrusion 31 on both sides of the toggle assembly 20 is completely detached from the body 11 and the side cover plate 12 of the insulating base 10).

[0070] Please refer to the following: Figure 5 and Figure 6 As shown, when the external force disengages from the toggle assembly 20 (i.e., the user releases the lever 22 of the toggle assembly 20), the clamping spring 40 can push the toggle assembly 20 through its own elasticity, thereby causing the toggle assembly 20 to rotate in the opposite direction of rotation D and reset to the clamping position P1. Furthermore, during the process of the toggle assembly 20 rotating from the release position P2 to the clamping position P1, the buffer structure 30 will generate frictional interference with the insulating base 10 and one of the toggle assemblies 20 (in this embodiment, the insulating base 10) to achieve a buffering and deceleration effect (in this embodiment, the side of each arc-shaped protrusion 31 facing the body 11 and the side facing the side cover plate 12 respectively completely abut against the body 11 and the side cover plate 12), thereby preventing the terminal block structure from being damaged or malfunctioning due to the strong impact of the toggle assembly 20. In addition, as the turning assembly 20 gets closer to the clamping position P1, the frictional interference area between the buffer structure 30 and the insulating base 10 and the other component of the turning assembly 20 (the insulating base 10 in this embodiment) increases, resulting in a better buffering and deceleration effect. In other words, the closer the turning assembly 20 is to the clamping position P1, the better the buffering and deceleration effect of the buffer structure 30, thereby effectively reducing the reset force of the turning assembly 20 to avoid impact.

[0071] To further explain, in this embodiment, each arc-shaped protrusion 31 extends gradually in the opposite direction to the rotation direction D. Therefore, during the process of the turning assembly 20 rotating from the release position P2 to the clamping position P1, frictional interference will begin to occur between the thicker parts of each arc-shaped protrusion 31 and the insulating base 10, and the frictional interference area increased during the reset process will gradually decrease. In this way, not only can a significant buffering and deceleration effect be ensured when each arc-shaped protrusion 31 first contacts the insulating base 10, but the turning assembly 20 can also be prevented from completely stopping before rotating back to the clamping position P1 due to excessive frictional interference force of the buffer structure 30, thus avoiding failure to reset smoothly.

[0072] See also Figure 1 and Figure 2 As shown, the terminal block of this utility model further includes a conductive terminal 50, which forms an electrical connection with the wire and transmits power or signals to the outside of the insulating body 11. Specifically, the conductive terminal 50 includes a first conductive piece 51, a second conductive piece 52, a connecting plate 53, and several pins 54. The connecting plate 53 is connected between the first conductive piece 51 and the second conductive piece 52. The first conductive piece 51 and the second conductive piece 52 correspond to the two ends of the clamping spring 40 and are fixed in the receiving groove 111. The first conductive piece 51 is located between the operating port 112 and the second conductive piece 52. Each pin 54 extends from the second conductive piece 52 to the outside of the body 11. Thus, when the turning assembly 20 is in the clamping position P1, the clamping spring 40 and the second conductive piece 52 can jointly clamp the wire, and transmit power or signals to the outside for use through the pins 54 of the conductive terminal 50. In this embodiment, the connecting plate 53 is essentially vertically connected between the first conductive sheet 51 and the second conductive sheet 52, and the first conductive sheet 51 and the second conductive sheet 52 are essentially parallel to each other, but this utility model is not limited thereto.

[0073] To further explain, the clamping spring 40 includes a fixed section 41, a movable section 42, and a bending section 43. The bending section 43 is bent and connected between the fixed section 41 and the movable section 42. The fixed section 41 is fixed to the first conductive plate 51, while the movable section 42 elastically abuts against the turning assembly 20 and extends toward the second conductive plate 52. Thus, when the turning assembly 20 is in the clamping position P1, the end of the movable section 42 elastically abuts against the second conductive plate 52, and when the wire is inserted from the insertion hole 113 into the receiving groove 111, the end of the movable section 42 and the second conductive plate 52 together clamp and fix the wire, forming an electrical connection.

[0074] It should be noted that multiple terminal blocks with a buffer structure of this utility model can be connected in series simultaneously. Specifically, as shown in the example... Figure 1As shown, the second terminal block (i.e., the second terminal block on the right) does not require the side cover plate 12. Instead, its body 11 can be connected to the second side surface 115 of the body 11 of the first terminal block (i.e., the rightmost terminal block) via its first side surface 114. This allows the rotating assembly 20 of the second terminal block to be positioned away from the arc-shaped protrusion 31 of its body 11, corresponding to the second side surface 115 of the body 11 of the first terminal block, thus achieving a buffering and deceleration effect. The remaining terminal blocks can also be assembled and connected in series in the same manner. In other words, except for the first terminal block (i.e., the rightmost terminal block) which requires the side cover plate 12, the remaining terminal blocks can be directly connected and fixed to the second side surface 115 of the body 11 of the other terminal block adjacent to it on the right.

[0075] Please continue reading. Figure 7 The diagram shows the second embodiment of this invention. The main difference between this embodiment and the first embodiment is that each arc-shaped protrusion 31 is respectively positioned on the side of the main body 11 facing the turning assembly 20 and on the side of the side cover plate 12 facing the turning assembly 20. Therefore, when the turning assembly 20 rotates from the release position P2 to the clamping position P1, each arc-shaped protrusion 31 completely abuts against the side of the turning assembly 20 facing the main body 11 and the side of the turning assembly 20 facing the side cover plate 12. When the turning assembly 20 is in the release position P2, each arc-shaped protrusion 31 completely disengages from the turning assembly 20. In other words, this embodiment achieves the same buffering and deceleration effect as the first embodiment; the difference lies only in the position of each arc-shaped protrusion 31 in the buffer structure 30.

[0076] The form of the buffer structure 30 of this utility model is not limited to the above-described embodiments. For example, please refer to... Figures 8 to 12 As shown, this is the third embodiment of the present invention. The main difference between this embodiment and the first embodiment is that the buffer structure 30 includes several protrusions 32. A portion of these protrusions 32 are located on the side of the turning assembly 20 facing the side cover plate 12, while the remaining portions are located on the side of the side cover plate 12 facing the turning assembly 20 and are positioned corresponding to the positions of the protrusions 32 on the turning assembly 20. Therefore, when the turning assembly 20 rotates from the release position P2 to the clamping position P1, the protrusions 32 on the turning assembly 20 abut against the protrusions 32 on the side cover plate 12. When the turning assembly 20 is in the release position P2, the protrusions 32 on the turning assembly 20 are completely disengaged from the protrusions 32 on the side cover plate 12. In other words, in this embodiment, the protrusions 32 on the rotating assembly 20 will only begin to interfere with each other and generate friction with each other on the side cover plate 12 to form a buffering and deceleration effect when the rotating assembly 20 rotates and resets to a position close to the clamping position P1. In this embodiment, the protrusions 32 are arranged in a matrix, but this utility model is not limited to this, and the arrangement of the protrusions 32 should be adjusted accordingly according to different needs.

[0077] To further explain, in order to enable multiple terminal blocks with buffer structures in this embodiment to be connected in series simultaneously, a portion of the plurality of protrusions 32 of the buffer structure 30 are disposed on the second side 115 of the body 11 (i.e., the side of the body 11 away from the turning assembly 20), and each protrusion 32 on the body 11 is configured to correspond to the position of each protrusion 32 disposed on the turning assembly 20, i.e., as shown below. Figure 9 As shown. Therefore, when multiple terminal blocks with buffer structures of this embodiment are connected in series, except for the rightmost terminal block which requires a side cover plate 12, each of the other terminal blocks can be fixed to the second side 115 of the body 11 of the other terminal block adjacent to its right, and the buffering and deceleration effect is achieved by the protrusions 32 on the second side 115 of the body 11 of the other terminal block adjacent to its right.

[0078] Please refer to the following: Figure 13 As shown, this is the fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that the buffer structure 30 further includes several grooves 33, while the turning assembly 20 does not have any protrusions 32 on the side facing the side cover plate 12. Specifically, in this embodiment, each protrusion 32 of the buffer structure 30 is disposed on the side of the side cover plate 12 facing the turning assembly 20 and on the second side surface 115 of the body 11. Each groove 33 of the buffer structure 30 is formed on the side of the turning assembly 20 facing the side cover plate 12, and each groove 33 is respectively positioned corresponding to the protrusions 32 disposed on the side cover plate 12. When the turning assembly 20 is in the clamping position P1, each protrusion 32 is engaged in the groove 33. This not only improves the positioning effect of the turning assembly 20 when it rotates to the clamping position P1, but also further increases the frictional interference between the protrusions 32 of the buffer structure 30 and the grooves 33 of the turning assembly 20, thereby improving the buffering and deceleration effect of the turning assembly 20 during the reset process.

[0079] Please refer to the following: Figure 14 As shown, this is the fifth embodiment of the present invention. The difference between this embodiment and the third embodiment is that neither the side cover plate 12 nor the main body 11 has any protrusions 32. Instead, only the side of the turning assembly 20 facing the side cover plate 12 has protrusions 32. In other words, the buffer structure 30 in this embodiment is only provided on the turning assembly 20. Therefore, regardless of whether the turning assembly 20 is in the clamping position P1, the release position P2, the process of rotating from the clamping position P1 to the release position P2, or the process of rotating back from the release position P2 to the clamping position P1, each protrusion 32 on the turning assembly 20 will abut against the side of the side cover plate 12 facing the turning assembly 20, or the second side 115 of the main body 11 of the adjacent terminal block on its right side, thus achieving a buffering and deceleration effect.

[0080] Please refer to the following: Figure 15 As shown, this is the sixth embodiment of the present invention. The difference between this embodiment and the fifth embodiment is that the protrusions 32 are disposed on the side cover plate 12 and the body 11, while the turning assembly 20 does not have any protrusions 32. Specifically, in this embodiment, a portion of the protrusions 32 are disposed on the side of the side cover plate 12 facing the turning assembly 20, while the remaining portions are disposed on the second side surface 115 of the body 11, corresponding to the positions of the protrusions 32 disposed on the side cover plate 12. This achieves the same effect as the fifth embodiment, that is, regardless of whether the turning assembly 20 is in the clamping position P1, the release position P2, the process of rotating from the clamping position P1 to the release position P2, or the process of rotating back from the release position P2 to the clamping position P1, the protrusions 32 on the side cover plate 12 or the protrusions 32 on the second side surface 115 of the body 11 of the adjacent terminal block on its right side will abut against the side of the turning assembly 20 away from the body 11, thus achieving a buffering and deceleration effect.

[0081] The terminal block with a buffer structure of this utility model, by setting the buffer structure 30 in at least one of the insulating base 10 and the turning assembly 20, when the external force disengages from the turning assembly 20 and causes the clamping spring 40 to push the turning assembly 20 to reverse and reset, the buffer structure 30 can gradually generate frictional interference with the other one of the insulating base 10 and the turning assembly 20 during the reset process of the turning assembly 20, thereby playing a buffering and deceleration effect, so as to avoid damage or failure of the terminal block structure due to the strong impact of the turning assembly 20.

[0082] In summary, the foregoing disclosure of this utility model is intended to enable those skilled in the art to clearly understand the technical content of this utility model and implement it accordingly, and is not intended to limit the scope of patent protection of this utility model. In addition, this utility model may have other embodiments not listed. Without departing from the spirit and essence of this utility model, those skilled in the art should be able to devise various corresponding changes and modifications based on this utility model, but all such changes and modifications should fall within the scope of protection of the patent application filed for this utility model.
