Abstract
Description
Technical Field
[0001] This utility model relates to the field of pressure pad technology, and in particular to a terminal block, wire connection structure and pressure pad. Background Technology
[0002] In existing technologies, pressure pads determine the pressure applied to their surface and the user's posture by detecting changes in capacitance or resistance at multiple points, allowing the user to adjust their sitting, standing, or lying posture. The pressure pad comprises an upper fabric layer, a middle insulating layer, and a lower fabric layer stacked together. The upper fabric layer has upper conductive wires along a first direction, and the lower fabric layer has lower conductive wires along a second direction. A controller applies a high potential to the upper conductive wires and keeps the lower conductive wires at a low potential. When pressure is applied to a certain area of the pressure pad, the upper and lower conductive wires in the corresponding area make effective contact through the middle insulating layer, generating a noticeable electrical signal and thus achieving pressure detection.
[0003] In related technologies, conductive lines are electrically connected to the controller via FPC (Flexible Printed Circuit). For example, the FPC is bonded to a fabric layer and its gold fingers contact the conductive lines to achieve electrical connection. The gold fingers and conductive lines can also be soldered together to reinforce the connection. However, when the pressure pad is under stress, significant stress can easily occur at the connection between the FPC and the fabric layer. This can cause the FPC to detach from the fabric layer, disconnecting the FPC from the conductive lines and leading to pressure pad failure. Utility Model Content

[0028] Furthermore, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0029] Firstly, please refer to Figure 1 and Figure 2 This utility model embodiment provides a terminal block 100. The terminal block 100 is used to electrically connect two conductive components, such as connecting two conductive wires.
[0030] Please see Figure 1 and Figure 2The terminal block 100 includes a first terminal block 1, a second terminal block 2, and a connecting part 3. The connecting part 3 connects the first terminal block 1 and the second terminal block 2. The first terminal block 1 has a conductive wire crimping part 11, which is used to crimp conductive wires on the conductive layer of the fabric. The second terminal block 2 has a wire crimping part 21, which is used to crimp wires. It is understood that the first terminal block 1 and the second terminal block 2 are conductors, and the connecting part 3 is a conductor or is connected to the first terminal block 1 and the second terminal block 2 through other conductors, thereby electrically connecting the conductive wires and the wires. Optionally, the first terminal block 1, the second terminal block 2, and the connecting part 3 are all made of metal, such as copper or aluminum alloy. Optionally, the first terminal block 1, the second terminal block 2, and the connecting part 3 are integrally formed, such as by stamping or casting a metal sheet, to reduce production costs and improve the connection strength between the connecting part 3 and the first terminal block 1 and the second terminal block 2.
[0031] For a clearer description of the structural features and beneficial effects of the terminal block 100, please refer to [link / reference]. Figures 3 to 5 This utility model embodiment provides a pressure pad 200, which includes a first woven conductive layer 201 and a second woven conductive layer 202 stacked together. The woven conductive layer includes a woven carrier and conductive wires. The first woven conductive layer 201 includes a first woven carrier 2011 and a first conductive wire 2012 disposed on the side of the first woven carrier 2011 facing the second woven conductive layer 202. The second woven conductive layer 202 includes a second woven carrier 2021 and a second conductive wire 2022 disposed on the side of the second woven carrier 2021 facing the first woven conductive layer 201. The first conductive wires 2012 extend along a first direction X, and the second conductive wires 2022 extend along a second direction Y. There are M first conductive wires 2012 arranged at intervals along the second direction Y, and N second conductive wires 2022 arranged at intervals along the first direction X. The M first conductive wires 2012 and N second conductive wires 2022 form M*N sensing points. M and N are both positive integers.
[0032] M first conductive lines 2012 and N second conductive lines 2022 are all electrically connected to the controller 203. The controller 203 sequentially performs high-frequency electrical signal cyclic scanning on the M*N sensing points formed by the first conductive lines 2012 and the second conductive lines 2022. When a certain area of the sensing pad is compressed, the first fabric conductive layer 201 and the second fabric conductive layer 202 move closer to each other in that area, and the sensing point corresponding to that area is connected to generate an electrical signal. This allows the upper computer to display the signal of the corresponding area being compressed, thus realizing pressure detection.
[0033] In related technologies, the conductor is bonded to the fabric carrier, allowing the conductor to contact the conductive wire and achieve electrical connection. However, the connection strength between the conductor and the fabric carrier is low. When stress is generated between the two, the conductor is prone to detaching from the fabric carrier, causing the conductor to break away from the conductive wire and resulting in the failure of the pressure pad 200.
[0034] In this embodiment of the invention, the wire and the conductive wire are electrically connected via the terminal block 100. The conductive wire crimping part 11 of the first terminal block 1 is used to crimp the conductive wire on the conductive fabric layer. By crimping the conductive wire with the conductive wire crimping part 11, the reliability of the electrical connection between the conductive wire crimping part 11 and the conductive wire is improved, thus enhancing the reliability of the electrical connection between the wire and the conductive wire. Furthermore, the conductive wire crimping part 11 can pierce the fabric carrier of the conductive fabric layer and connect the fabric carrier to the first terminal block 1, improving the reliability of the electrical connection between the wire and the fabric carrier. This further mitigates the problem of easy failure of the pressure pad 200 and enhances the reliability of the pressure pad 200.
[0035] In some embodiments, please refer to Figure 1 and Figure 2 The second terminal 2 is provided with an insulating crimping portion 22, which is used to crimp the insulation layer covering the conductor. Exemplarily, the insulating crimping portion 22 includes two insulating crimping teeth 221, spaced apart along the width direction of the first terminal 1, specifically positioned on opposite sides of the first terminal 1 along its width direction. The two insulating crimping teeth 221 can be bent closer together by external force, such as by clamping with wire clamps, so that the two insulating crimping teeth 221 clamp the insulation layer of the conductor, thereby fixing the conductor. The crimping by the insulating crimping portion 22 allows the terminal 100 to be stably connected to the insulation layer covering the conductor, and keeps the conductor in position. The insulating crimping portion 22 can also directly crimp the conductor core. One or more sets of insulating crimping portions 22 can be provided. When there are multiple sets of insulating crimping portions 22, these sets can be arranged along the extending direction of the second terminal 2. Optionally, the insulation crimping teeth 221 have pointed tips, allowing them to embed into the insulation layer of the conductor, thereby enhancing the clamping effect on the conductor. Optionally, the insulation crimping teeth 221 are triangular in shape.
[0036] In some embodiments, please refer to Figure 1 In the insulation crimping portion 22, two insulation crimping teeth 221 are arranged alternately along the extension direction of the second terminal 2, and the insulation crimping teeth 221 in the same group are staggered in the width direction. Therefore, when the insulation crimping teeth 221 are bent closer to each other by external force, the two insulation crimping teeth 221 are less likely to interfere with each other, thus improving the problem that the insulation crimping teeth 221 cannot press the wire tightly due to interference between the two insulation crimping teeth 221.
[0037] For the above-mentioned conductive wire crimping part 11, please refer to Figure 1 and Figure 2 The conductive wire crimping part 11 includes two conductive wire crimping teeth 111, which are spaced apart along the width direction of the first terminal 1, specifically arranged on opposite sides of the first terminal 1. The conductive wire crimping teeth 111 pierce and press against the woven conductive layer to achieve connection with it, improving the reliability of the electrical connection between the conductive wire crimping part 11 and the conductive wire, thereby improving the reliability of the electrical connection between the terminal 100 and the conductive wire. After passing through the woven conductive layer, the conductive wire crimping teeth 111 can be bent closer together by external force, such as by clamping with wire clamps, so that the two conductive wire crimping teeth 111 clamp the woven carrier and the conductive wire, thereby fixing the conductive wire crimping part 11 to the woven carrier and the conductive wire. The conductive wire crimping part 11 can have one or more sets. When there are multiple sets of conductive wire crimping parts 11, they can be arranged along the extension direction of the first terminal 1. Optionally, the conductive wire crimping teeth 111 have sharp points, making it easy for the conductive wire crimping teeth 111 to pass through the fabric carrier. Optionally, the conductive wire crimping teeth 111 are triangular in shape.
[0038] In some embodiments, the two conductive wire crimping teeth 111 of the conductive wire crimping portion 11 are staggered along the extending direction of the first terminal 1. Therefore, when the conductive wire crimping teeth 111 are bent closer together by external force, the two conductive wire crimping teeth 111 are less likely to interfere with each other, thus improving the problem of the two conductive wire crimping teeth 111 interfering with each other and causing the conductive wire crimping teeth 111 to fail to press the conductive wire and the fabric carrier tightly.
[0039] In a preferred embodiment, the length of the conductive wire crimping teeth 111 of the conductive wire crimping portion 11 is less than the length of the insulating skin crimping teeth 221, and the two conductive wire crimping teeth 111 of the conductive wire crimping portion 11 are arranged opposite each other along the width direction of the first terminal 1.
[0040] In some embodiments, please refer to Figure 1 The length of the insulating crimping teeth 221 is greater than that of the conductive wire crimping teeth 111. The conductive wire can typically be in the form of a thin sheet, such as copper foil or a printed circuit on an FPC (Flexible Printed Circuit), or cylindrical, such as a silk thread; alternatively, multiple conductive wires may converge to a main wire, which may be a silk thread, copper foil, or a printed circuit. The conductive wire crimping teeth 111 penetrate the woven conductive layer and expose their tips, and the conductive wire crimping portion 11 is crimped to the conductive wire or the main wire to achieve electrical connection. The conductor is typically a plastic-coated wire with a diameter greater than the thickness of the woven conductive layer. The insulating crimping teeth 221 need to clamp the conductor; therefore, the length of the insulating crimping teeth 221 is greater than that of the conductive wire crimping teeth 111 to accommodate the conductor.
[0041] For the wire crimping part 21 mentioned above, please refer to Figure 1 and Figure 2 The wire crimping portion 21 includes two wire crimping teeth 211, spaced apart along the width direction of the second terminal 2, specifically positioned on opposite sides of the second terminal 2. The two wire crimping teeth 211 can be bent closer together by external force, such as by clamping with wire clamps, to clamp the wire core of the conductor, electrically connecting the terminal 100 to the conductor and ensuring the reliability of the electrical connection between the wire crimping portion 21 and the conductor. The wire crimping portion 21 can have one or more sets. When there are multiple sets of wire crimping portions 21, they can be arranged along the extension direction of the second terminal 2. Optionally, the wire crimping portion 21 is rectangular in shape, increasing the contact area between the wire crimping portion 21 and the wire core, improving the electrical connection effect, and simultaneously mitigating the problem of the wire crimping portion 21 breaking the wire core.
[0042] In some embodiments, please refer to Figure 1 and Figure 2 The wire crimping portion 21 is located at one end of the second terminal 2 adjacent to the connecting portion 3, and the insulation crimping portion 22 is located at the end of the second terminal 2 away from the connecting portion 3. For example, the wire crimping portion 21 is located at the connection between the second terminal 2 and the connecting portion 3, and the insulation crimping portion 22 is located at the end of the second terminal 2 away from the connecting portion 3. When the end of the conductor is exposed to the insulation, the insulation crimping portion 22 and the wire crimping portion 21 respectively crimp the insulation and the exposed part of the conductor.
[0043] In some embodiments, please refer to Figure 1 The first terminal 1 is provided with a first wiring groove 12. Along the width direction of the first wiring groove 12, two conductive wire crimping teeth 111 of the conductive wire crimping part 11 are provided on opposite sides of the first wiring groove 12. The two conductive wire crimping teeth 111 can be symmetrically arranged on opposite sides of the first wiring groove 12. By providing the first wiring groove 12, the conductive wire and the corresponding fabric carrier can be accommodated within the first wiring groove 12, enhancing the clamping effect of the conductive wire crimping part 11 on the fabric carrier and the conductive wire.
[0044] In some embodiments, please refer to Figure 1 The second terminal 2 is provided with a second wiring groove 23. Along the width direction of the second wiring groove 23, two wire crimping teeth 211 of the wire crimping part 21 are provided on opposite sides of the second wiring groove 23. By providing the second wiring groove 23, the wire can be accommodated in the second wiring groove 23, enhancing the clamping effect of the second wiring groove 23 on the wire.
[0045] In some embodiments, please refer to Figure 1The second terminal 2 is provided with a second terminal groove 23. Along the width direction of the second terminal groove 23, two insulating skin crimping teeth 221 of the insulating skin crimping part 22 are provided on opposite sides of the second terminal groove 23. By providing the second terminal groove 23, the wire can be accommodated in the second terminal groove 23, enhancing the clamping effect of the insulating skin crimping part 22 on the insulation of the wire.
[0046] Secondly, this utility model provides a wire connection structure, which includes a wire, a woven conductive layer, and a terminal block 100. The woven conductive layer includes a woven carrier and conductive wires disposed on the woven carrier. The first terminal block 1 of the terminal block 100 is pressed onto the woven carrier of the woven conductive layer through a conductive wire crimping part 11, and the conductive wire crimping part 11 is pressed onto the conductive wire. The second terminal block 2 of the terminal block 100 is pressed onto the wire through a wire crimping part 21. That is, the wire connection structure includes the terminal block 100 and the first woven conductive layer 201 and / or the second woven conductive layer 202 in the pressure pad 200, and may not include other components of the pressure pad 200. The wire connection structure uses the terminal block 100 to connect the wire to the woven conductive layer and realizes electrical connection with the conductive wires in the woven conductive layer, thereby improving the connection stability between the wire and the woven conductive layer and improving the reliability of the electrical connection between the wire and the conductive wires.
[0047] In some embodiments, the conductive wire crimping portion 11 pierces and presses the fabric carrier. That is, after the two conductive wire crimping teeth 111 of the same group pass through the fabric carrier, they are bent closer to each other by external force, such as by clamping with wire clamps, so that the two conductive wire crimping teeth 111 clamp the fabric carrier and the conductive wire, and fix the conductive wire crimping portion 11 to the fabric carrier and the conductive wire.
[0048] The structure of the pressure pad 200 described above will be explained in detail below. For some embodiments, please refer to [link / reference needed]. Figures 3 to 5 The pressure pad 200 includes a controller 203, a connector 204, and a wire connection structure. The wire is electrically connected to the connector 204, and the connector 204 is electrically connected to the controller 203. The controller 203 is used to scan the M*N sensing points formed by the first conductive line 2012 and the second conductive line 2022 with electrical signals. The connector 204 is used for pluggable connection with the controller 203, and the connector 204 is electrically connected to the wire, thereby facilitating the connection and disconnection of the controller 203 and the wire. When one of them is damaged, the other can be easily replaced, reducing the maintenance cost of the pressure pad 200.
[0049] In some embodiments, please refer to Figure 4 and Figure 6In a group of M first conductive wires 2012, each group of a first conductive wires 2012 converges to a first main line 2013. The first main line 2013 connects to the terminal block 100. After multiple first conductive wires 2012 converge to the first main line 2013, the conductive wire crimping portion 11 of the first terminal block 1 of the terminal block 100 pierces and crimps onto the first fabric carrier 2011 of the first woven conductive layer 201. The first terminal block 1 crimped onto the first fabric carrier 2011 contacts the first main line 2013, thus achieving electrical connection between a first conductive wires 2012 and the same terminal block 100, i.e., electrical connection with the same conductor. Depending on the requirements, a ≤ M, and the range of a can be set to 1 ≤ a ≤ 10. Optionally, a is 1.
[0050] In some embodiments, please refer to Figure 5 and Figure 7 Of the N second conductive wires 2022, each b second conductive wires 2022 converge to a second main wire 2023. The second main wire 2023 connects to the terminal block 100. After multiple second conductive wires 2022 converge to the second main wire 2023, the conductive wire crimping portion 11 of the first terminal block 1 of the terminal block 100 pierces and crimps onto the second fabric carrier 2021 of the second fabric conductive layer 202. The first terminal block 1 crimped onto the second fabric carrier 2021 contacts the second main wire 2023, achieving electrical connection between the b second conductive wires 2022 and the same terminal block 100, i.e., electrical connection with the same conductor. Depending on the requirements, b ≤ N, and the range of b can be set to 1 ≤ b ≤ 10. Optionally, b is 1.
[0051] In some embodiments, please refer to Figure 4 and Figure 5The pressure pad 200 includes an isolation layer 205, which is located between the first woven conductive layer 201 and the second woven conductive layer 202. All M*N sensing points are located within the common coverage area of the isolation layer 205. It should be noted that in a flat position, the first woven conductive layer 201, the isolation layer 205, and the second woven conductive layer 202 can be considered as being stacked sequentially. The isolation layer 205 separates the first woven conductive layer 201 from the second woven conductive layer 202, preventing direct conduction between the first conductive wire 2012 and the second conductive wire 2022. When the first woven conductive layer 201 and the second woven conductive layer 202 compress the isolation layer 205 to a certain extent, for example, compressing the isolation layer 205 by 50% of its thickness, the first conductive wire 2012 and the second conductive wire 2022 corresponding to this compressed area will become conductive, or the standard for considering the first conductive wire 2012 and the second conductive wire 2022 as conductive will be reached, thus generating pressure feedback. Alternatively, the isolation layer 205 can be a pressure-sensitive layer, whose resistance is inversely proportional to the applied pressure. When the pressure on the pressure-sensitive layer reaches a certain threshold, the current in the first conductive line 2012 and the second conductive line 2022 reaches the conduction standard, thereby generating pressure feedback. This improves the problem that the pressure pad 200 detects pressure even when subjected to relatively small pressure, resulting in an excessively low detection threshold for the pressure pad 200.
[0052] In some embodiments, please refer to Figure 4 and Figure 5 The pressure pad 200 includes an insulating layer that corresponds to the positions of the first main wire 2013 and the second main wire 2023. For example, please refer to... Figure 8 and Figure 9 The insulating layer includes a first insulating layer 206 and a second insulating layer 207. The first insulating layer 206 and the second insulating layer 207 are respectively disposed on opposite sides of the isolation layer 205 along the thickness direction. The first insulating layer 206 corresponds to the position of the first main wire 2013, preventing the first main wire 2013 from conducting with the second main wire 2023 and the second conductive wire 2022; the second insulating layer 207 corresponds to the position of the second main wire 2023, preventing the second main wire 2023 from conducting with the first main wire 2013 and the first conductive wire 2012. Optionally, the first insulating layer 206 and the second insulating layer 207 are bonded to the isolation layer 205, or respectively bonded to the first woven conductive layer 201 and the second woven conductive layer 202.
