This achieves the effect of inserting and removing wires without the need for tools.

Description

Terminal block with blocking function Technical Field

[0001] This application relates to terminal blocks, and in particular to a terminal block with a blocking function. Prior Technology

[0002] Terminal blocks are electronic components widely used in various machines or tools that require electrical connections. They can be used to connect wires such as power lines, control lines, or data transmission lines.

[0003] In the current terminal block, when performing wire insertion operations, it is usually necessary to use tools such as flathead screwdrivers to apply pressure to the clamping part commonly known as the handle, so as to disengage the spring inside the terminal block, allowing the wire to be inserted and positioned smoothly. Then, the clamping part is released, and the spring clamps the wire and makes an electrical connection.

[0004] However, during the above operation, the user must use the aforementioned tool with one hand to maintain pressure on the pressure switch while inserting the wire with the other hand, which makes the operation of the existing terminal block quite troublesome and inconvenient, and has long been criticized.

[0005] Therefore, how to overcome the shortcomings of the aforementioned prior technologies is a major issue that the creator of this application urgently needs to address. Summary of the Invention

[0006] The purpose of this application is to provide a terminal block with a blocking function, which can prevent the pressed slider from remaining in the position after the wire clamping spring arm has been pressed down.

[0007] To achieve the above objectives, this application provides a terminal block with a stopping function for inserting a wire and comprising: an insulating base having a mating chamber and an insertion hole and a sliding groove, the insertion hole and the sliding groove respectively communicating with the mating chamber; a slider slidably disposed within the sliding groove and having a top pin and a claw; a first spring piece disposed within the mating chamber of the insulating base and having a wire clamping spring arm; and a stopping spring arm correspondingly disposed within the mating chamber and having a stopping portion and a raised section. The wire clamping spring arm is located between the top pin and the raised section; wherein, by pressing the slider and sliding it in the groove, the top pin can push the wire clamping spring arm to swing in one direction, and the hook can also be turned upside down onto the stop; the wire is inserted into the docking chamber through the socket, which can push the raised section to cause the stop to disengage from the hook, and the wire clamping spring arm can also elastically return to its original position in the opposite direction and push the top pin back while simultaneously pushing the slider to slide in the groove.

[0010] In one embodiment, the fixing structure includes a plurality of protrusions, a gap is formed between two adjacent protrusions, and the fixing part is continuously bent into a bent frame corresponding to at least one protrusion and at least one gap, and the bent frame is fixed to the plurality of protrusions.

[0011] In one embodiment, the stop arm of the second spring has a notch, and the stop arm forms a plurality of sides at the notch by opening the notch, one of the plurality of sides becoming the stop portion.

[0012] In one embodiment, the fixing structure includes a protruding wall and a protrusion protruding from the protruding wall, a neck connecting the protrusion and the protruding wall, a gap being formed between the protrusion and the protruding wall through the neck, and the fixing part including a sheet with a notch, the fixing part being fixed to the fixing structure by being inserted into the gap through the sheet and into the notch through the neck.

[0013] In one embodiment, the protruding wall is provided with a groove, and one end of the sheet can be embedded in the groove.

[0014] In one embodiment, the sheet body forms two opposing sides at the notch by opening the notch, each side protruding with a tooth, the two teeth protruding opposite each other and biting the neck together.

[0015] In one embodiment, the second spring has an opening in its stop arm, and the stop arm forms a plurality of inner edges at the opening, one of which becomes the stop portion.

[0016] In one embodiment, the stop arm is connected to the first spring.

[0017] In one embodiment, the first spring sheet further includes a fixed spring arm and a bent portion. The clamping spring arm is connected to one end of the bent portion, and the stop spring arm and the fixed spring arm are both connected to the other end of the bent portion. The fixed spring arm is positioned on the insulating base, and both the clamping spring arm and the stop spring arm can elastically deflect relative to the fixed spring arm by being subjected to force.

[0018] In one embodiment, the clamping spring arm and the fixed spring arm have a first included angle, and the blocking spring arm and the fixed spring arm have a second included angle, wherein the first included angle is greater than the second included angle.

At this time, the released wire clamping spring arm can return to its original position to hold the wire, and the slider can also be pushed back to its original position. Therefore, this application eliminates the need for tools for wire insertion and removal operations. Simple Explanation of the Diagram

[0044] The detailed description and technical content of this application are illustrated below with reference to the accompanying drawings. However, the accompanying drawings are provided for reference and illustration only and are not intended to limit this application.

[0045] This application provides a terminal block with a blocking function (hereinafter referred to as: terminal block), as shown in FIG1, which can prevent the pressed slider 2 from remaining in the position after the wire clamping spring arm 32 has been pressed down. The terminal block of this application includes three embodiments, as shown in FIG1 to FIG10 as the first embodiment, as shown in FIG11 to FIG16 as the second embodiment, and as shown in FIG17 to FIG20 as the third embodiment.

[0046] As shown in Figures 1 to 10, the first embodiment of the terminal block of this application is used to insert a wire W, which includes: an insulating base 1, a pair of sliders 2, a pair of first springs 3a, a pair of stop spring arms 52 (or 55) and a conductor 9.

[0047] The insulating base 1 is a plastic base body, which has a pair of docking chambers 11. The insulating base 1 has a sliding groove 12 and a socket 13 arranged side by side at intervals for each docking chamber 11. The sliding groove 12 and the socket 13 are respectively connected to the docking chamber 11. Specifically, the insulating base 1 has a fixing structure 15a installed in the docking chamber 11.

[0048] It should be noted that the structures of each pair of docking chambers 11 (including the fixing structure 15a therein) are the same, the structures of each pair of sliders 2 are the same, the structures of each pair of first springs 3a are the same, and the structures of each pair of stop arms 52 (or 55) are also the same. Therefore, the terminal block of this application only needs to include one slider 2, one first spring 3a and one stop arm 52 (or 55). In order to avoid going into too much detail, only one of each pair will be described below.

[0049] The slider 2 is slidably inserted into the groove 12 and can extend into the docking chamber 11 after sliding. The slider 2 can be a straight column with a top pin 21 and a hook 22 located on the same straight line. Specifically, the slider 2 also has a connecting channel 23 on the same straight line, and the connecting channel 23 is located between the top pin 21 and the hook 22. The slider 2 can slide relative to the groove 12 in a pressed direction (as shown by the straight arrow in Figure 8) by being pressed. The hook 22 can be a convex hook with a backing function, the backing direction of which is opposite to the pressed direction of the slider 2, and the protruding direction of the hook 22 is perpendicular to or crosses the pressed direction. The top pin 21 can be a convex pin protruding in the pressed direction.

[0050] The first spring piece 3a can be a metal elastic sheet formed by integral bending, so that the first spring piece 3a has a fixed spring arm 31 and a wire clamping spring arm 32 with its bending point as the boundary, and there is an included angle between the fixed spring arm 31 and the wire clamping spring arm 32 (refer to the component symbol A1 shown in Figure 20). The first spring piece 3a is disposed in the insulating base 1 in the docking chamber 11. After being disposed, it can fix the fixed spring arm 31. As shown in Figure 6, the wire clamping spring arm 32 extends laterally across the inner end of the slide groove 12 and the inner end of the socket 13 in the docking chamber 11 (the inner end refers to the end located in the docking chamber 11). The wire clamping spring arm 32 can also elastically deflect relative to the fixed spring arm 31 to avoid the inner end of the socket 13 after being subjected to force (see Figure 8).

[0051] The stop spring arm 52 (or 55) is correspondingly disposed within the docking chamber 11. The stop spring arm 52 (or 55) has a raised section 522 and a stop portion 524, and the aforementioned clamping spring arm 32 is located between the top pin 21 and the raised section 522. The raised section 522 can elastically deflect relative to the stop spring arm 52 (or 55) by force, and the raised section 522 is raised towards the inner end of the socket 13. It should be noted that this application does not limit how the stop spring arm 52 (or 55) is disposed within the docking chamber 11. It can be fixed to the insulating base 1 or fixed to other components. In this first embodiment, the terminal block of this application further includes a second spring piece 5a as an example for description, and the second spring piece 5a has a stop spring arm 52 (or: the stop spring arm 52 is fixed to the second spring piece 5a).

[0052] As shown in Figures 6 and 7, when the slider 2 is in its initial state before being pressed, its top pin 21 protrudes towards the wire clamping spring arm 32 along the pressing direction but does not contact the wire clamping spring arm 32 (not shown in the figures). Preferably, as shown in the figures, the top pin 21 protrudes towards the wire clamping spring arm 32 along the pressing direction and abuts against the wire clamping spring arm 32. It should be noted that at this time, the wire clamping spring arm 32 passes laterally through the inner end of the slide groove 12 and the inner end of the insertion hole 13 via the aforementioned connecting channel 23.

[0053] The second spring plate 5a is disposed in the insulating base 1 within the docking chamber 11. It has a fixing part 51 and the aforementioned stop spring arm 52. The fixing part 51 is fixed to the aforementioned fixing structure 15a. The second spring plate 5a can be a metal elastic sheet, which can be made to have the fixing part 51 and the stop spring arm 52 in various ways. In this embodiment, it is integrally bent to form the fixing part 51 and the stop spring arm 52. The stop spring arm 52 is integrally bent to have a connecting section 521 and the aforementioned raised section 522, which are bounded by the bending point. One end of the stop spring arm 52 is integrally connected to the fixing part 51, so that the stop spring arm 52 can elastically deflect relative to the fixed part 51 by force. The connecting section 521 connects one end of the fixing part 51 and the raised section 522.

[0054] The second spring 5a can also have the aforementioned stop 524 in various ways. For example, it can be made by protruding a lug on the stop arm 52 as the stop 524 (not shown in the figure). In this embodiment, as shown in Figures 3 and 7, a notch 523 is opened in the stop arm 52 (or the raised section 522) to form a plurality of side edges 5231 at the notch 523. The plurality of side edges 5231 together define the notch 523, and one of the plurality of side edges 5231 becomes the desired stop 524.

[0055] Conductor 9 is a long strip of metal frame. Conductor 9 is embedded in insulating base 1 and at least one end of it extends into the corresponding docking chamber 11. As shown in the figure, both ends of conductor 9 extend into the corresponding two docking chambers 11.

[0056] As shown in Figures 6 to 10, when the user wants to insert the wire W, they first press the exposed slider 2 at the outer end of the slide groove 12 with their own finger, causing the slider 2 to slide relative to the slide groove 12 in the pressing direction (e.g., downwards). At the same time, the top pin 21 pushes the wire clamping spring arm 32 to elastically deflect in a direction closer to the fixed spring arm 31 (thus generating an elastic restoring force in the wire clamping spring arm 32) and causes the hook 22 to snap onto the stop part 524. At this time, in addition to allowing... The wire clamping spring arm 32 no longer extends laterally beyond the inner end of the socket 13, which facilitates the insertion of the wire W. Furthermore, because the hook 22 is inverted and locked onto the stop part 524, it can stop the sliding block 2 from being elastically pushed back in the opposite direction of the aforementioned sway direction by the wire clamping spring arm 32 (for example, being pushed upward). This push-back force comes from the elastic restoring force of the wire clamping spring arm 32, thereby allowing the sliding block 2 to remain in the position after the wire clamping spring arm 32 has been pressed down (see Figure 8), which facilitates the insertion of the wire W.

[0057] Next, the user can insert the wire W into the socket 13 and extend it into the docking chamber 11. At the insertion end, the free end of the wire W pushes the raised section 522, causing the entire stop arm 52 to elastically deflect relative to the fixed part 51 in an unlocking direction closer to the fixed arm 31. After the deflection, the stop part 524 disengages from the hook 22. At this time, since the hook 22 is no longer inverted on the stop part 524, the wire clamping arm 32 can elastically reset and push the slider 2 back, simultaneously pushing the wire W towards the conductor 9, so that the wire W and the conductor 9 come into contact and conduct (see Figure 10), and the wire W is clamped and positioned between the wire clamping arm 32 and the conductor 9.

[0058] As soon as the wire W is inserted, the wire W pushes the raised section 522, causing the hook 22 to no longer bend over and stop at the stop part 524 (that is, it no longer stops the slider 2). This allows the wire clamping spring arm 32 to push the slider 2 back during its elastic reset (at this time, the wire clamping spring arm 32 is only half reset). Therefore, when the user presses the slider 2 again to make the wire clamping spring arm 32 no longer clamp the inserted wire W, the user can pull the wire W out of the socket 13, allowing the wire clamping spring arm 32 to fully reset and push the slider 2 back completely, that is, push it back until the top of the slider 2 is roughly flush with one of the outer walls of the insulating base 1 (see Figure 7).

[0059] Therefore, the terminal block of this application allows the wire clamping spring arm 32 to retract from the inner end position of the insertion hole 13 by pressing the slider 2, facilitating the insertion of the wire W. After the wire W is inserted into the positioning position, the wire clamping spring arm 32 can be released by the wire W touching the raised section 522 of the stop spring arm 52. At this time, the wire clamping spring arm 32 can be reset to hold the wire W, and the slider 2 can also be reset. Therefore, the operation of the wire W by the terminal block of this application does not require the use of tools.

[0060] Specifically, as shown in Figures 4 and 6, in order to fix the second spring piece 5a, the aforementioned fixing structure 15a may include a plurality of protrusions 151, each protrusion 151 being arranged at intervals and a gap G1 being formed between any two adjacent protrusions 151; as for the second spring piece 5a, its aforementioned fixing part 51 may be continuously bent into a bending frame 511 corresponding to at least one protrusion 151 and at least one gap G1, so that the bending frame 511 can be fixed to the plurality of protrusions 151 and each gap G1 as shown in Figure 6.

[0061] As shown in Figures 11 to 16, this is a second embodiment of the terminal block of this application. The second embodiment is largely the same as the first embodiment, except that the second spring 5b and the fixing structure 15b used to fix the second spring 5b are different from those in the first embodiment, as described below. In the second embodiment, the first spring 3a is the same as the first spring 3a in the first embodiment.

[0062] Similar to the first embodiment described above, this second embodiment does not limit how the stop spring arm 55 is configured in the docking chamber 11. It can be fixed to the insulating base 1 or to other components. In this second embodiment, the terminal block of this application further includes a second spring piece 5b as an example, and the second spring piece 5b has a stop spring arm 55.

[0063] In the second embodiment, the second spring piece 5b is also disposed in the insulating base 1 within the docking chamber 11. It has a fixing part 54 and the aforementioned stop spring arm 55, and the fixing part 54 is fixed to the aforementioned fixing structure 15b. The second spring piece 5b can be a metal elastic sheet, which can be made to have the fixing part 54 and the stop spring arm 55 in various ways. In this embodiment, it is formed by integral bending to have the fixing part 54 and the stop spring arm 55. The stop spring arm 55 is integrally bent to have a connecting section 551 and a raised section 552 that can be bounded by its bending point. One end of the stop spring arm 55 is integrally connected to the fixing part 54, so that the stop spring arm 55 can elastically deflect relative to the fixed part 54 by force. The connecting section 551 is connected between one end of the fixing part 54 and the raised section 552.

[0064] The second spring 5b can also have a stop portion 554 in various ways. For example, it can be a stop portion 554 (not shown in the figure) by protruding a lug on the stop arm 55. In this embodiment, as shown in Figures 13A, 13B and 15, an opening 553 is opened in the stop arm 55 (or the raised section 552) to form a plurality of inner edges 5531 at the opening 553. The plurality of inner edges 5531 together define the opening 553, and one of the plurality of inner edges 5531 becomes the desired stop portion 554.

[0065] Therefore, the terminal block of this application allows the wire clamping spring arm 32 to retract from the inner end position of the insertion hole 13 by pressing the slider 2, facilitating the insertion of the wire W. After the wire W is inserted into the positioning position, the wire clamping spring arm 32 can be released by the wire W touching the raised section 552 of the stop spring arm 55. At this time, the wire clamping spring arm 32 can be reset to hold the wire W, and the slider 2 can also be reset. Therefore, the operation of the terminal block of this application for the wire W does not require the use of tools. In other words, this second embodiment has all the effects of the first embodiment described above.

[0066] Specifically, as shown in Figures 13A, 13B, and 14 to 16, in order to fix the second spring piece 5b, the aforementioned fixing structure 15b may include a protruding wall 155 and a protrusion 156. The protrusion 156 protrudes from one side of the protruding wall 155, and a neck 157 is connected between the protrusion 156 and the protruding wall 155 as shown in Figure 15, so that a gap G2 is formed between the protrusion 156 and the protruding wall 155 through the neck 157. As for the second spring piece 5b, its fixing part 54 is a single piece 541. A notch 5411 is opened on one side of the piece 541, so that the fixing part 54 can be fixed to the fixing structure 15b by inserting the piece 541 into the gap G2 and by inserting the neck 157 into the notch 5411, as shown in Figures 15 and 16. The piece 541 is sandwiched between the protrusion 156 and the protruding wall 155.

[0067] Preferably, as shown in Figures 13A and 13B, the sheet 541 has a notch 5411, at which two opposing side edges 5412 are formed. Each side edge 5412 has a protruding tooth 5413, and the two protruding teeth 5413 protrude opposite each other so as to bite the neck 157 together, as shown in Figure 16. In this way, the fixing effect of the fixing part 54 to the fixing structure 15b is improved.

[0068] Furthermore, as shown in Figures 14 and 15, a groove 1551 may be formed on the protruding wall 155, with the groove 1551 and the gap G2 spaced apart and opposite to each other, so that one end of the piece 541 can be further embedded in the groove 1551. In this way, the fixing effect of the fixing part 54 to the fixing structure 15b is more stable.

[0069] As shown in Figures 17 to 20, this is the third embodiment of the terminal block of this application. The third embodiment is generally the same as the first and second embodiments, except that the first spring 3c of the third embodiment is different from the first spring 3a of the first and second embodiments, the stop spring arm 36 of the third embodiment is different from the stop spring arms 52 and 55 of the first and second embodiments, and the third embodiment does not include the second spring and the fixing structure for fixing the second spring.

[0070] Similar to the first and second embodiments described above, this third embodiment does not limit how the stop arm 36 is configured in the docking chamber 11. It can be fixed to the insulating base 1 or to other components. In this third embodiment, the stop arm 36 is directly connected to the first spring piece 3c as an example for explanation.

[0071] In the third embodiment, the first spring piece 3c can also be a metal elastic sheet formed by integral bending, so that the first spring piece 3c has a fixed spring arm 35 and a wire clamping spring arm 32 with its bending point as the boundary, and there is a first included angle A1 between the fixed spring arm 35 and the wire clamping spring arm 32 (see Figure 20). The first spring piece 3c is disposed in the docking chamber 11 on the insulating base 1. After being disposed, it can fix the fixed spring arm 35. As shown in Figure 20, the wire clamping spring arm 32 also laterally crosses the inner end of the slide groove 12 and the inner end of the insertion hole 13 in the docking chamber 11, and the wire clamping spring arm 32 can also elastically swing relative to the fixed spring arm 35 to avoid the inner end of the insertion hole 13 (not shown in the figure). Among them, the fixed spring arm 35 and the blocking spring arm 36 of this third embodiment can be regarded as being formed by directly splitting the fixed spring arm in the first and second embodiments into two, as shown in Figures 19A and 19B.

[0072] Specifically, the first spring 3c also has a bent portion 37, with a wire clamping spring arm 32 connected to one end of the bent portion 37, and a stop spring arm 36 and a fixed spring arm 35 connected side by side to the other end of the bent portion 37. The fixed spring arm 35 is positioned on the insulating base 1, so that both the wire clamping spring arm 32 and the stop spring arm 36 can elastically deflect relative to the fixed spring arm 35 under force.

[0073] This application does not specify how the stop arm 36 should be formed. In this embodiment, the stop arm 36 is formed by integral bending, so that the stop arm 36 has a connecting section 361 and a raised section 362 bounded by its bending point. One end of the stop arm 36 is integrally connected to the aforementioned bending portion 37, so that the stop arm 36 can elastically deflect relative to the bending portion 37 (or relative to the fixed spring arm 35) under force. The connecting section 361 connects one end of the bending portion 37 and the raised section 362. As shown in FIG20, there is a second included angle A2 between the stop arm 36 and the fixed spring arm 35. Since the stop arm 36 is located between the clamping spring arm 32 and the fixed spring arm 35, the aforementioned first included angle A1 is greater than the second included angle A2.

[0074] Therefore, the terminal block of this application can retract the wire clamping spring arm 32 from the inner end position of the insertion hole 13 by pressing the slider 2, which facilitates the insertion of the wire W; after the wire W is inserted into the positioning position, the wire clamping spring arm 32 can be released by the wire W touching the raised section 362 of the stop spring arm 36. At this time, in addition to the wire clamping spring arm 32 returning to hold the wire W, the slider 2 can also be driven to return to the original position. Therefore, the operation of the terminal block of this application for the wire W does not require the use of tools. In other words, this third embodiment has all the effects of the first and second embodiments described above.

[0075] Specifically, as shown in Figures 19A and 19B, the stop arm 36 can also have a stop portion 364 in various ways. For example, a lug protruding from the stop arm 36 can serve as the stop portion 364 (not shown in the figure). In this embodiment, as shown in the figure, a notch 363 is opened in the stop arm 36 (or the raised section 362) to form a plurality of side edges 3631 at the notch 363. The plurality of side edges 3631 together define the notch 363, and one of the plurality of side edges 3631 becomes the desired stop portion 364.

[0076] In summary, the terminal block with blocking function in this application can indeed achieve the expected use purpose and effect, and can solve the shortcomings of the prior art. Therefore, this patent application is filed.
