Description

Technical Field

[0001] This invention relates to the field of optoelectronic signal transmission technology, and in particular to an electrical connection component capable of transmitting multiple signals. Background Technology

[0002] Connectors are installed at points of interruption or between isolated circuits for interlocking connections between devices, enabling the transmission of current and signals. Existing single printed circuit board (PCB) connectors cannot directly connect to multiple fixed-socket connectors of different series on a device to transmit signals. To enable PCB connectors to connect to multiple fixed connectors on a device and achieve one-to-one transmission of various signals, two common structures are used: the first connection structure is as follows... Figure 1 As shown, the pins of the printed circuit board connector 1 are directly inserted into the through holes on the printed circuit board 2. Multiple connectors 3 are used at the other end of the printed circuit board 2, with the pins 4 of the connectors 3 soldered to the printed circuit board 2. The multiple connectors 3 are then connected to a fixed socket connector on the device. This connection method cannot achieve long-distance transmission; when the two devices are far apart, they cannot be directly connected. Furthermore, this connection method is inconvenient for maintenance and does not easily support the transmission of multiple different signals. The second connection structure is as follows: Figure 2 As shown, the pins of the printed circuit board connector 1 are directly inserted into the through holes on the printed circuit board 2. The other end of the connector 3 is soldered with a wire 5, connecting the wire 5 to the printed circuit board 2 by forming a solder mark 6. This enables the connection and signal transmission between the printed circuit board connector 1 and multiple connectors 3. However, this connection method is not suitable for frequent plugging and unplugging, and maintenance is inconvenient. Replacement or repair requires resoldering, which may damage the printed circuit board 2 and the wire 5. Furthermore, this connection method has low reliability; in a vibrating environment, the location of the solder mark 6 is easily stressed, affecting connection reliability and posing a potential hazard. Summary of the Invention

[0003] In view of this, the purpose of this application is to provide an electrical connection component that can realize multiple signal transmissions, so as to solve the problems of existing structures for connecting multiple fixed connectors on printed circuit boards to equipment, which cannot realize long-distance transmission or are not conducive to frequent plugging and unplugging, are inconvenient to maintain, and have low connection reliability in vibration environments.

[0055] The electrical connection assembly for realizing multiple signal transmissions provided by the present invention includes a PCB board 10, a first connector 20, an adapter 30, a second connector 40, and a connection assembly 50.

[0056] In the following text, the specific structure of the above-described components of the electrical connection assembly capable of transmitting various signals according to this embodiment will be described.

[0057] In this embodiment, as Figure 4 As shown, the PCB board 10 is a printed circuit board, the main body of which is formed into a plate-shaped structure, having a first transmission end 11 and a second transmission end 12, and the first output end and the second output end can be disposed on opposite sides of the PCB board 10.

[0058] like Figure 3 As shown, in this embodiment, the first connector 20 is a printed circuit board connector, which is mounted on the first transmission end 11. Specifically, the pins of the printed circuit board connector can be soldered to the first transmission end 11. The adapter 30 is a metal part mounted on the second transmission end 12, for example, it can be soldered to the second transmission end 12. Figure 5 As shown, the adapter 30 has a connecting portion 31 that protrudes from the surface of the PCB board 10, so that a protruding structure is formed on the surface of the PCB board 10, and the adapter 30 is fixedly connected to the PCB board 10.

[0059] In this embodiment, the second connector 40 is provided with a plug-in portion 42 for connecting to a socket on the device to be connected. One or more second connectors 40 can be provided according to the needs of the device to be connected. When multiple second connectors 40 are provided, at least some of them can be connectors of different models or structures, enabling various signal transmissions and meeting different signal transmission requirements, as long as the connection requirements of the socket on the device are met. It should be noted that when multiple second connectors 40 are provided, all second connectors 40 can also be identical.

[0060] like Figure 3 As shown, a cable 41 is led out from one end of the second connector 40. The cable 41 and the plug part 42 can be arranged opposite each other or at an angle. In addition, the cable 41 can be integrally formed with the second connector 40, or the cable 41 can be welded and fixed to the second connector 40.

[0061] Specifically, the end of cable 41 away from the second connector 40 has at least one core wire 411 extending toward the PCB board 10. That is, the number of core wires 411 leading out on each cable 41 can be one or more, which can be set according to different cable 41 specifications or different signals transmitted. It should be noted that the core wire 411 can be formed by stripping the outer insulation layer from one end of the cable 41 to expose the inside, and the length of the cable 41 can be adjusted according to the installation distance requirements.

[0062] like Figure 3 , Figure 10 and Figure 11 As shown, the connecting component 50 is configured in a one-to-one correspondence with the core wires 411. For example, when four sets of core wires 411 are led out from a cable 41, the connecting component 50 is configured with four sets accordingly, and each set of core wires 411 is fixed to a different adapter 30. The connecting component 50 and the adapter 30 are rotatably connected, thus meeting the requirements for wire output in different directions. The long-distance connection between the first connector 20 and the second connector 40 is achieved by assembling the core wires 411 and the adapter 30 through the connecting component 50.

[0063] Specifically, such as Figures 6 to 9As shown, the connecting assembly 50 includes a press-fit component 51, a snap-fit ​​component 52, and an insulating component 53. The press-fit component 51 and the snap-fit ​​component 52 are metal parts, and the insulating component 53 can be a plastic part with insulating properties. The press-fit component 51 is connected to the core wire 411 and the snap-fit ​​component 52 respectively. By adjusting the specifications of the press-fit component 51, different functions and different specifications of cables 41 can be used. The snap-fit ​​component 52 is formed as a cylindrical structure sleeved on the connecting part 31. The snap-fit ​​component 52 has an elastic snap protrusion 520 protruding towards the inside of the cylindrical structure. The elastic snap protrusion 520 abuts against the connecting part 31, which can achieve quick connection and convenient plugging and unplugging. When changing the transmission of different signals, there is no need to desolder the PCB board 10, so as not to damage the PCB board 10. This meets the needs of frequent replacement or installation, improves the reliability of electrical connection, and enhances the stability of signal transmission.

[0064] It should be noted that in this embodiment, when the second connector 40 needs to be replaced, the connecting component 50 on the core wire 411 corresponding to the second connector 40 can be pulled out entirely from the adapter 30. It should be further noted that in this embodiment, wiring can be completed simply by inserting or pressing the connecting component 50 onto the adapter 30, which greatly improves efficiency; and it occupies little space, with the outer diameter of the adapter 30 being only a few millimeters. By adjusting the number of adapters 30, multiple signals can be transmitted, solving the problem of signal transmission failure due to insufficient space.

[0065] In this embodiment, as Figure 3 , Figures 7 to 10 As shown, the insulating element 53 is sleeved on the outside of the snap-fit ​​element 52 to provide electrical insulation.

[0066] In a preferred embodiment, such as Figures 7 to 9 As shown, the insulating component 53 includes an insulating shell 531 and an insulating cap 532. The insulating shell 531 is formed as a cylindrical structure surrounding the circumferential sidewall of the snap-fit ​​component 52. The snap-fit ​​component 52, the connecting part 31, and the pressing part 511 on the pressing part 51, as described below, are all disposed inside the insulating shell 531. There is a gap between the inner wall of the insulating shell 531 and the circumferential outer wall of the snap-fit ​​component 52. The insulating cap 532 is disposed on the side of the insulating shell 531 away from the PCB board 10, and is used to close the opening on the side of the insulating shell 531 away from the PCB board 10 after the pressing part 51 is assembled. One of the insulating shell 531 and the insulating cap 532 has a protruding mounting part 5321, and the other has a mounting space 5312 for the mounting part 5321 to extend into. This realizes the snap-fit ​​connection between the insulating shell 531 and the insulating cap 532, which has the advantages of convenient installation and reliable connection.

[0067] Specifically, such as Figure 8As shown, the assembly space 5312 is formed as a hole or groove and is disposed on the insulating housing 531, and the assembly part 5321 is formed as a protrusion and is disposed on the circumferential sidewall of the insulating cap 532, such that at least a portion of the insulating cap 532 can extend into the insulating housing 531 and connect with the insulating housing 531. In other alternative embodiments, the assembly space 5312 is disposed on the insulating cap 532, and the assembly part 5321 is disposed on the insulating housing 531.

[0068] Preferably, the assembly part 5321 is provided with multiple assembly parts 5321 arranged in a ring at intervals, and the assembly space 5312 is provided in a one-to-one correspondence with the assembly part 5321, so as to improve the snap-fit ​​reliability of the insulating shell 531 and the insulating cap 532.

[0069] Furthermore, in this embodiment, as Figures 7 to 9 As shown, the insulating housing 531 has a receiving groove 5311 on its side wall for the pressure device 51 to extend into, and the receiving groove 5311 is preferably located on the top of the insulating housing 531.

[0070] Furthermore, in this embodiment, as Figure 8 As shown, the end of the insulating cap 532 facing the insulating shell 531 contacts the surface of the press-fit 51 facing away from the snap-fit ​​52, thereby improving the connection reliability between the press-fit 51 and the snap-fit ​​52 and reducing the risk of separation between the press-fit 51 and the snap-fit ​​52; a limiting part 5313 extending radially inward along the adapter 30 is formed on the side of the insulating shell 531 near the PCB board 10, and the snap-fit ​​52 contacts the surface of the limiting part 5313 facing away from the PCB board 10, thereby limiting the displacement of the snap-fit ​​52 within the insulating shell 531 and improving the installation reliability between the snap-fit ​​52 and the adapter 30.

[0071] Preferably, such as Figure 8 As shown, the limiting part 5313 is formed into a ring structure, and there is a gap between the adapter 30 and the limiting part 5313.

[0072] In this embodiment, as Figure 5 As shown, the second transmission end 12 has multiple connection holes 100 for installing the adapter 30. The adapter 30 is formed as a strip structure that passes through the connection hole 100. After the adapter 30 passes through the connection hole 100, it is soldered and fixed to the PCB board 10. The connecting part 31 is provided at one end of the length direction of the adapter 30. The other end of the length direction of the adapter 30 can be formed as an insertion part 32 that passes through the connection hole 100 and partially exits from the connection hole 100. The radial dimension of the insertion part 32 of the adapter 30 is smaller than the radial dimension of the connecting part 31 of the adapter 30.

[0073] It should be noted that the radial direction of the adapter 30 is... Figure 5The horizontal direction from the perspective of the adapter 30 is the axial direction. Figure 5 The vertical direction from the perspective.

[0074] Specifically, such as Figure 5 As shown, the connecting part 31 includes a first column part 311, an abutment part 312, and a second column part 313 arranged sequentially along the length direction of the adapter 30. The abutment part 312 protrudes from the circumferential sidewalls of the first column part 311 and the second column part 313. The first column part 311 is located at the end of the abutment part 312 away from the PCB board 10, and the second column part 313 is located at the end of the abutment part 312 close to the PCB board 10. The second column part 313 can abut against the surface of the PCB board 10 to limit the axial movement of the adapter 30 and improve the welding reliability between the adapter 30 and the PCB board 10.

[0075] More specifically, in this embodiment, as Figure 5 As shown, the abutting portion 312 includes a first abutting portion 3121 and a second abutting portion 3122 arranged sequentially along the length direction of the adapter 30. The first abutting portion 3121 and the second abutting portion 3122 are connected. The end of the first abutting portion 3121 away from the second abutting portion 3122 is connected to the first column portion 311, and the end of the second abutting portion 3122 away from the first abutting portion 3121 is connected to the second column portion 313, so that the first column portion 311, the first abutting portion 3121, the second abutting portion 3122 and the second column portion 313 are arranged sequentially along the length direction of the adapter 30. In the direction in which the adapter 30 extends into the connecting hole 100, the radial dimension of the first abutment portion 3121 gradually increases, and the radial dimension of the second abutment portion 3122 gradually decreases, so that the outer walls of both the first abutment portion 3121 and the second abutment portion 3122 are inclined. The elastic latching protrusion 520 includes a first latching protrusion 521 and a second latching protrusion 522. The first latching protrusion 521 abuts against the first column portion 311, and the second latching protrusion 522 abuts against the second abutment portion 3122. The assembly of the second latching protrusion 522 and the second abutment portion 3122 realizes the latching connection between the adapter 30 and the latching member 52. The assembly of the first latching protrusion 521 and the first column portion 311 plays a role in improving the latching tightness. More importantly, it forms a double-layer contact to increase the current carrying capacity and improve the stability of signal transmission.

[0076] The first latching protrusion 521 and the second latching protrusion 522 can be formed into a bent sheet-like structure to make it elastic, ensuring that the elastic latching protrusion 520 and the adapter 30 form good contact.

[0077] In a preferred embodiment, such as Figure 5As shown, the angle between the outer wall of the first abutment 3121 and the axis of the adapter 30 is α, and the angle between the outer wall of the second abutment 3122 and the axis of the adapter 30 is β, where α < β. Preferably, 0° < α < 90° and 0° < β < 90°, so that the second abutment 3122 and the second latching protrusion 522 remain engaged under conditions such as vibration and impact, so that the force applied to pull the latching member 52 out of the adapter 30 is greater than the force applied to insert the latching member 52 into the adapter 30, thereby making it difficult for the adapter 30 to come out of the latching member 52.

[0078] Furthermore, such as Figure 5 As shown, the radial dimensions of the first column portion 311 and the second column portion 313 are the same; the dimension of the first abutment portion 3121 in the axial direction of the adapter 30 is greater than the dimension of the second abutment portion 3122 in the axial direction of the adapter 30, so as to ensure that the tilt angle of the second abutment portion 3122 is greater than the tilt angle of the first abutment portion 3121, so that the adapter 30 and the snap-fit ​​member 52 are easy to insert but not easy to pull out, thereby achieving reliable connection and reducing the risk of detachment in harsh environments such as vibration.

[0079] In a preferred embodiment, such as Figure 8 and Figure 9 As shown, multiple first latching protrusions 521 are provided, and the multiple first latching protrusions 521 are arranged circumferentially around the latching member 52 at intervals; and / or multiple second latching protrusions 522 are provided, and the multiple second latching protrusions 522 are arranged circumferentially around the latching member 52 at intervals. This increases the contact area between the elastic latching protrusions 520 and the adapter 30, increases the current carrying capacity, improves the stability of signal transmission, and also improves the reliability of the latching. While ensuring the rotatable connection between the latching member 52 and the adapter 30, it reduces the risk of the adapter 30 disengaging from the latching member 52.

[0080] In this embodiment, as Figures 6 to 9 As shown, one end of the press-fitting member 51 can be formed as a cylindrical structure surrounding the core wire 411. One end of the core wire 411 is embedded inside the press-fitting member 51 so that the core wire 411 is fixedly connected to the press-fitting member 51. The end of the press-fitting member 51 connected to the snap-fitting member 52 is formed as a press-fitting part 511. The press-fitting part 511 is formed as a plate-like structure. The press-fitting part 511 is provided with a mounting hole 512, which is a through hole penetrating the press-fitting part 511.

[0081] In this embodiment, the connecting component 50 further includes a fastener 54. The end of the snap-fit ​​member 52 away from the PCB board 10 has a plurality of folded portions 523 extending toward the axis of the snap-fit ​​member 52. Adjacent folded portions 523 are spaced apart from each other. The ends of the plurality of folded portions 523 facing the axis of the snap-fit ​​member 52 form an installation space 524 for installing the fastener 54. A deformation space 525 is formed between two adjacent folded portions 523. The fastener 54 passes sequentially through the mounting hole 512 on the press-fit part 511 and the installation space 524 on the snap-fit ​​member 52 to fix the press-fit part 51 and the snap-fit ​​member 52.

[0082] Specifically, such as Figure 8 and Figure 9 As shown, the fastener 54 includes a guide portion 541, a through portion 542, and a boss portion 543 arranged sequentially along the axial direction of the adapter 30. The guide portion 541 is located on the side close to the adapter 30. The radial dimension of the guide portion 541 gradually decreases in the direction in which the fastener 54 extends into the mounting space 524. The guide portion 541 is preferably formed into a hemispherical structure. Both the guide portion 541 and the boss portion 543 protrude from the circumferential sidewall of the through portion 542, such that the guide portion 541 abuts against the surface of the folded portion 523 facing the adapter 30, and the boss portion 543 abuts against the surface of the press-fit portion 511 facing away from the adapter 30. As the guide portion 541 passes through the installation space 524, it will compress the folded portion 523, causing the area of ​​the deformation space 525 to change. This increases the radial dimension of the installation space 524 to meet the passage requirements of the guide portion 541. After the guide portion 541 passes through, the folded portion 523 returns to its original position, allowing the guide portion 541 to abut against the surface of the folded portion 523 facing the adapter 30. The boss portion 543 can fold outward after the guide portion 541 passes through the installation space 524, abutting against the surface of the press-fit portion 511 facing away from the adapter 30. In this way, the press-fit portion 51 and the snap-fit ​​portion 52 are securely connected and cannot be easily disassembled. It should be noted that the fastener 54 can restrict the positional relationship between the press-fit part 51 and the snap-fit ​​part 52 in the axial direction, but will not restrict the positional relationship between the press-fit part 51 and the snap-fit ​​part 52 in the circumferential direction, so that the press-fit part 51 and the snap-fit ​​part 52 can rotate relative to each other. In this way, when the snap-fit ​​part 52 and the adapter 30 are tightly engaged, the direction of the core wire 411 can also be adjusted.

[0083] Furthermore, in this embodiment, such as Figure 3 As shown, the electrical connection component that can realize multiple signal transmissions also includes a first heat shrink member 61 and a second heat shrink member 62, and the first heat shrink member 61 and the second heat shrink member 62 can be heat shrink tubing.

[0084] Specifically, the first heat shrinkable part 61 is formed as a ring structure sleeved on the cable 41 to cover part of the circumferential sidewall of the cable 41. The outer side of the first heat shrinkable part 61 is marked. The mark can be formed by laser printing or other methods. The mark can be text and / or graphics, such as "Signal 1", "Signal 2", "Power", etc. The marks on different second connectors 40 are different, which helps to distinguish the different specifications of cables 41 on different second connectors and facilitates the identification of different signals transmitted by different cables 41.

[0085] like Figure 3 As shown, the second heat shrinkable part 62 is sleeved on the end of the core wire 411 away from the connecting component 50. Part of the second heat shrinkable part 62 covers the cable 41, so that the second heat shrinkable part 62 protects the end of the cable 41 that leads out of the core wire 411.

[0086] According to the present invention, an electrical connection assembly capable of transmitting multiple signals includes a PCB board having a first transmission end and a second transmission end; a first connector is mounted on the first transmission end; an adapter is mounted on the second transmission end, and a connecting portion protruding from the surface of the PCB board is formed on the adapter; a cable is led out from one end of the second connector, and the end of the cable away from the second connector has at least one core wire extending toward the PCB board; the connection assembly is rotatably connected to the adapter and is provided in a one-to-one correspondence with the core wire; the connection assembly includes a press-fit component, a snap-fit ​​component, and an insulating component; the press-fit component is connected to the core wire and the snap-fit ​​component respectively; the snap-fit ​​component is formed as a cylindrical structure sleeved on the connecting portion; and the snap-fit ​​component is further formed as a cylindrical structure sleeved on the connecting portion. The connector has an elastic locking protrusion that protrudes into the cylindrical structure and abuts against the connecting part. An insulating component is sleeved on the outside of the locking component, thus enabling long-distance connection between the first and second connectors and allowing for multiple signal transmissions to meet different signal transmission requirements. The core wire achieves a rotatable connection with the PCB board through the insertion and removal of the connecting component and the adapter, meeting the requirements for wire output in different directions. Insertion and removal are convenient, and the PCB board does not need to be desoldered when changing the transmission of different signals, thus avoiding damage to the PCB board. This meets the needs of frequent replacement or installation, ensuring the reliability of the electrical connection and improving the stability of signal transmission.
