terminal block

Abstract

A terminal base includes an insulating base, a side cover plate, a turning assembly and a clamping spring. The insulating base has a receiving groove and an operating opening. The receiving groove and the operating opening are located at different sides of the insulating base and are communicated with each other. The side cover plate is arranged on the insulating base and covers the receiving groove. The side cover plate has a stop rib located in the receiving groove. The turning assembly is rotatable between a clamping position and a releasing position. The turning assembly has a pivot part, a handle and a buffer groove. The pivot part is pivotally connected in the receiving groove. The handle penetrates through the operating opening. 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 so that the stop rib is clamped in the buffer groove. Thus, the turning assembly can be reset to have a buffer deceleration effect to avoid damage.

Description

Technical Field

[0001] This utility model relates to a terminal block, and more particularly to a terminal block with a turn-on assembly capable of buffering 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, including an insulating base, a side cover plate, a turning assembly, and a clamping spring. The insulating base has a receiving groove and an operating opening. The receiving groove is formed by recessing from one side of the insulating base inward. The operating opening is located on the other side of the insulating base and communicates with the receiving groove. The side cover plate is disposed on the insulating base and covers the receiving groove. The side cover plate has a braking rib located within the receiving groove. The turning assembly can be switched between a clamping position and a releasing position. Rotatably mounted between the insulating base and the side cover plate, the lever assembly has a pivot part, a lever, and a buffer groove. The pivot part is pivotally connected in the groove, the lever extends out of the operating port, and the clamping spring is disposed in the groove and elastically abuts against the lever assembly. When the lever assembly is pushed by an external force, the lever assembly rotates from the clamping position to the release position in a rotation direction. When the external force is released from the lever assembly, the clamping spring pushes the lever assembly to rotate in the opposite direction in the rotation direction so that the brake rib is engaged in the buffer groove.

[0007] In one embodiment of this utility model, the buffer groove is an arc-shaped groove, and the brake rib is an arc-shaped convex rib.

[0008] In one embodiment of the present invention, the turn-shifting assembly has a stop surface located in the buffer groove. When the turn-shifting assembly is in the clamping position, the brake rib abuts against the stop surface.

[0009] In one embodiment of the present invention, the brake rib extends to a positioning protrusion, and the turn assembly has a positioning groove communicating with the buffer groove. When the turn assembly is in the clamping position, the positioning protrusion is engaged in the positioning groove.

[0010] In one embodiment of the present invention, the brake rib has a positioning groove, and the turn assembly has a positioning protrusion disposed in the buffer groove. When the turn assembly is in the clamping position, the positioning protrusion is engaged in the positioning groove.

[0011] In one embodiment of this utility model, both the brake ribs and the buffer grooves are arranged adjacent to the operating port.

[0012] In one embodiment of the present invention, the insulating base has a first side surface and a second side surface opposite to each other, the receiving groove is formed by recessing from the first side surface inward, and the operating port is located between the first side surface and the second side surface.

[0013] In one embodiment of the present invention, the insulating base has another braking rib, which is formed by extending from the second side away from the first side and is positioned corresponding to the braking rib of the side cover plate.

[0014] In one embodiment of the present invention, the terminal block further includes a conductive terminal, which includes a first conductive sheet, a second conductive sheet and a connecting plate. The connecting plate is connected between the first conductive sheet and the second conductive sheet, and the first conductive sheet and the second conductive sheet are respectively fixed in the receiving groove by clamping the two ends of the spring sheet.

[0015] In one embodiment of the present invention, the clamping spring includes a fixed section, a movable section and a turning section, the turning section is connected between the fixed section and the movable section, the fixed section abuts against the first conductive sheet, and the movable section elastically abuts against the turning assembly and extends toward the second conductive sheet.

[0016] The terminal block of this utility model has brake ribs and buffer grooves respectively provided on the side cover plate and the turning assembly. Therefore, when the external force disengages from the turning assembly and causes the clamping spring to push the turning assembly to reverse and reset, the brake ribs of the side cover plate can gradually be inserted into the buffer groove of the turning assembly during the reset process, thereby achieving 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.

[0057] 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.

[0058] This utility model provides a terminal block for inserting and connecting an electrical wire (not shown in the figure). Please refer to [the following text is missing from the original] first. Figures 1 to 4 As shown, this is the first embodiment of the terminal block of the present invention, which mainly includes an insulating base 10, a side cover plate 20, a turning assembly 30 and a clamping spring 40.

[0059] The insulating base 10 has a receiving groove 11, an operating port 12, and a wire insertion hole 13. The receiving groove 11 is recessed inward from one side of the insulating base 10. Specifically, the insulating base 10 also has a first side surface 101 and a second side surface 102 arranged opposite to each other. The receiving groove 11 is recessed inward from the first side surface 101, and the operating port 12 and the wire insertion hole 13 are located on the remaining side between the first side surface 101 and the second side surface 102 and are respectively connected to the receiving groove 11. The wire insertion hole 13 is for inserting the wire from the outside of the insulating base 10 into the receiving groove 11 inside. Figure 1 and Figure 2 As shown, in this embodiment, the receiving groove 11 is formed by recessing inward from the first side surface 101 (i.e., the right side surface) of the insulating base 10. The operating port 12 is located on the top surface of the insulating base 10, and the insertion hole 13 is located on the front side surface of the insulating base 10. However, this utility model is not limited to this. For example, the receiving groove 11 can also be formed by recessing inward from the second side surface 102 (i.e., the left side surface) of the insulating base 10. The operating port 12 and the insertion hole 13 can be located simultaneously on the top surface, front side surface, rear side surface of the insulating base 10, or respectively on opposite sides of the insulating base 10, depending on the needs of use and design.

[0060] The side cover plate 20 is disposed on the insulating base 10 and covers the receiving groove 11. Specifically, in this embodiment, the side cover plate 20 is disposed on the first side 101 (i.e., the right side) of the insulating base 10 and covers the receiving groove 11. The side cover plate 20 and the insulating base 10 can be joined 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. The side cover plate 20 has a braking rib 21. The braking rib 21 protrudes from the side of the side cover plate 20 toward the insulating base 10 and is located in the receiving groove 11.

[0061] The toggle assembly 30 is rotatably disposed between the insulating base 10 and the side cover plate 20. Specifically, the toggle assembly 30 can rotate between a clamping position P1 and a releasing position P2. The toggle assembly 30 has a pivot portion 31, a lever 32, and a buffer groove 33. The pivot portion 31 is pivotally connected within a receiving groove 11 of the insulating base 10, thereby allowing the toggle assembly 30 to rotate relative to the insulating base 10. The lever 32 extends from the pivot portion 31 and protrudes into the operating port 12, allowing the user to operate the toggle assembly 30.

[0062] The clamping spring 40 is disposed within the receiving groove 11 of the insulating base 10, and the clamping spring 40 elastically abuts against the turning assembly 30. The clamping spring 40 is used to pre-press and fix the turning assembly 30 in the clamping position P1, thereby clamping and fixing the wire inserted from the insertion hole 13 within the receiving groove 11. Specifically, the clamping spring 40 can apply its own elastic force to the turning assembly 30, thereby fixing the turning assembly 30 in the clamping position P1 without external force, thus clamping and fixing the wire.

[0063] More specifically, when the lever 32 of the turning assembly 30 is pushed by the user with an external force greater than the elastic force of the clamping spring 40, the turning assembly 30 will rotate from the clamping position P1 to the release position P2 via its pivot 31. At this time, the clamping spring 40 will release the wire so that the user can pull it out of the plug hole 13 to the outside of the insulating base 10, or the user can insert the wire from the plug hole 13 into the receiving groove 11 inside the insulating base 10.

[0064] When the external force disengages from the lever assembly 30 (i.e., the user releases the lever 32 of the lever assembly 30), the clamping spring 40 can push the lever assembly 30 through its own elasticity, causing the lever assembly 30 to rotate in the opposite direction of rotation D and reset to the clamping position P1. Furthermore, during the reset process of the lever assembly 30 from the release position P2 to the clamping position P1, the brake rib 21 of the side cover plate 20 gradually engages with the buffer groove 33 of the lever assembly 30. This frictional interference between the brake rib 21 and the buffer groove 33 provides a buffering and deceleration effect, thereby preventing damage or malfunction of the terminal block structure due to the strong impact of the lever assembly 30.

[0065] In this embodiment, the buffer groove 33 is an arc-shaped groove, and the brake rib 21 is an arc-shaped convex rib. Both the brake rib 21 and the buffer groove 33 are positioned adjacent to the operating port 12 of the insulating base 10, so that when the toggle assembly 30 rotates from the release position P2 to the clamping position P1, the buffer groove 33 can gradually engage with the brake rib 21, providing a good buffering effect. However, the shape and position of the buffer groove 33 and the brake rib 21 in this invention are not limited to this. The toggle assembly 30 has a stop surface 34. The stop surface 34 is located within the buffer groove 33, meaning that the buffer groove 33 has only a single opening for the brake rib 21 to engage. Therefore, when the toggle assembly 30 rotates to the clamping position P1, one end of the brake rib 21 abuts against the stop surface 34 to form a positioning effect, thereby preventing the toggle assembly 30 from rotating excessively and providing a protective effect.

[0066] In addition, to enable multiple terminal blocks of this invention to be connected in series simultaneously, the insulating base 10 also has another braking rib 14, such as... Figure 2 As shown. Specifically, the other braking rib 14 of the insulating base 10 extends from the second side 102 in a direction away from the first side 101, and the position of the other braking rib 14 of the insulating base 10 corresponds to the position of the braking rib 21 of the side cover plate 20. Therefore, see again Figure 1 As shown, the second terminal block (i.e., the second terminal block on the right) does not require the side cover plate 20. Instead, its first side surface 101 of the insulating base 10 can be connected to the second side surface 102 of the insulating base 10 of the first terminal block (i.e., the rightmost terminal block). This allows the other braking rib 14 of the insulating base 10 of the first terminal block to be configured corresponding to the buffer groove 33 of the turning assembly 30 of the second terminal block. 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 20, the remaining terminal blocks can be directly connected and fixed to the second side surface 102 of the insulating base 10 of the other terminal block adjacent to it on the right.

[0067] Further explanation: The terminal block of this utility model also includes a conductive terminal 50 for forming an electrical connection with the wire and transmitting power to the outside of the insulating base 10. 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 11. The first conductive piece 51 is located between the operating port 12 and the second conductive piece 52. Each pin 54 extends from the second conductive piece 52 to the outside of the insulating base 10. Thus, when the turning assembly 30 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.

[0068] 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 30 and extends toward the second conductive plate 52. Thus, when the turning assembly 30 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 13 into the receiving groove 11, the end of the movable section 42 and the second conductive plate 52 can jointly clamp and fix the wire, forming an electrical connection.

[0069] Please continue reading. Figures 5 to 7The diagram shows the second embodiment of this invention. The main difference between this embodiment and the first embodiment is that the brake rib 21 extends with at least one positioning protrusion 60, and the turning assembly 30 has at least one positioning groove 70 communicating with the buffer groove 33. Therefore, when the turning assembly 30 rotates from the release position P2 to the clamping position P1, the positioning protrusion 60 is engaged within the positioning groove 70. This not only further improves the positioning effect of the turning assembly 30 but also increases the frictional interference between the brake rib 21 and the buffer groove 33, thereby improving the buffering and deceleration effect of the turning assembly 30 during the reset process. In this embodiment, there are two positioning protrusions 60 and two positioning grooves 70, resulting in better buffering and positioning effects. However, this invention is not limited to this; for example, the number of positioning protrusions 60 and three or more positioning grooves 70 can also be one. In this embodiment, each positioning protrusion 60 and each positioning groove 70 are arranged sequentially along the arc of the corresponding brake rib 21 and buffer groove 33. That is, each positioning protrusion 60 is located on the same side of the brake rib 21, and each positioning groove 70 is also located on the same side of the buffer groove 33. However, this utility model is not limited thereto.

[0070] Please refer to the following: Figure 8 The diagram shows the third embodiment of this utility model, which differs from the second embodiment mainly in the placement of the positioning protrusions 60 and positioning grooves 70. Specifically, in this embodiment, the positioning protrusions 60 are disposed within the buffer grooves 33 of the turning assembly 30, while the positioning grooves 70 are formed on the brake ribs 21 of the side cover plate 20. Thus, the positioning protrusions 60 and positioning grooves 70 can also improve the positioning effect of the turning assembly 30 and increase the frictional interference between the brake ribs 21 and the buffer grooves 33, thereby improving the buffering and deceleration effect of the turning assembly 30 during the reset process.

[0071] The terminal block of this utility model has brake ribs 21 and buffer grooves 33 respectively provided on the side cover plate 20 and the rotating assembly 30. Therefore, when the external force disengages from the rotating assembly 30 and the clamping spring 40 pushes the rotating assembly 30 to reverse and reset, the brake ribs 21 of the side cover plate 20 can gradually be inserted into the buffer grooves 33 of the rotating assembly 30 during the reset process, thereby achieving a buffering and deceleration effect, so as to avoid damage or failure of the terminal block structure due to the strong impact of the rotating assembly 30.

[0072] 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.
