Description

Technical Field

[0001] The embodiments of this disclosure generally relate to the installation of a display, and more specifically, to a connector for a display and a method for detecting the installation orientation of the display. Background Technology

[0002] Industrial equipment typically includes controllers and displays. Controllers are configured to control the operation of the industrial equipment and can be installed in field devices. Displays are set to show the status or control conditions of the industrial equipment so that users can monitor the equipment.

[0003] Monitors typically connect to controllers via a plug. Traditional monitors have predetermined display modes, thus requiring them to be installed to the controller in a predetermined orientation. To prevent incorrect installation, the interface between the monitor and controller is designed to allow unidirectional insertion. However, such a unidirectional interface is prone to damage; in particular, during use, if the controller and monitor are improperly oriented, forceful installation can damage the connectors. Therefore, improvements to the connector structure between the monitor and controller are desired. Summary of the Invention

[0029] In the various figures, the same or corresponding reference numerals indicate the same or corresponding parts. Detailed Implementation

[0030] Preferred embodiments of the present disclosure will now be described in more detail with reference to the accompanying drawings. While preferred embodiments of the present disclosure are shown in the drawings, it should be understood that the present disclosure may be implemented in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that the present disclosure will be thorough and complete, and will fully convey the scope of the present disclosure to those skilled in the art.

[0031] The term "comprising" and its variations as used herein signify an open-ended inclusion, i.e., "including but not limited to". Unless otherwise stated, the term "or" means "and / or". The term "based on" means "at least partially based on". The terms "one example embodiment" and "one embodiment" mean "at least one example embodiment". The term "another embodiment" means "at least one additional embodiment". Terms such as "upper", "lower", "front", and "rear", indicating placement or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are used only for the purpose of describing the principles of this disclosure, and are not intended to indicate or imply that the elements referred to must have a specific orientation, be constructed or operated in a specific orientation, and therefore should not be construed as limiting this disclosure.

[0032] As mentioned earlier, the interface between the monitor and controller can only allow unidirectional insertion due to mechanical structure settings. In this case, the interface is easily damaged by forceful insertion by the user. To address this, the applicant of this application provides a new connector structure that allows bidirectional insertion between the monitor and controller. However, even with the design of the pin-based mechanical structure allowing bidirectional insertion, abnormal data display still exists between the monitor and controller. For example, when the monitor and controller are installed in a predetermined first orientation, the monitor typically displays data in normal mode; however, when installed in a second orientation, the monitor may display data in reverse order, resulting in abnormal data display. Therefore, in addition to improving the mechanical structure of the connector between the monitor and controller, the problem of data display between the monitor and controller must also be solved.

[0033] The connector according to embodiments of this disclosure provides a design that allows bidirectional insertion and can detect the mounting orientation between a display and a controller. Its structure is simple and easy to implement. The connector according to embodiments of this disclosure will now be described in detail with reference to the accompanying drawings. It is worth noting that although the embodiments of this disclosure use a connector between a display and a controller as an example to illustrate the connector structure according to embodiments of this disclosure, the connector structure of embodiments of this disclosure is not limited to displays and controllers, but can be equivalently applied to other interface devices involving mounting orientation and data communication.

[0034] Figure 1 A schematic diagram of the overall structure of a display system 100 according to an embodiment of the present disclosure is shown. Figure 2 A schematic block diagram of a display system 100 according to an embodiment of the present disclosure is shown. Figure 1 As shown, the display system 100 includes a display 10 and a controller 20. The display 10 can be configured to provide data display for user monitoring. The controller 20 can be configured to perform status detection and control of field industrial equipment, causing the equipment to operate in a predetermined manner. The controller 20 is adapted to be coupled to and communicate with the display 10. The controller 20 can, for example, be connected to or mounted to field equipment. The display 10 can be connected to the controller 20 via a connector 30.

[0035] like Figure 2As shown, the display 10 may include a display module 12 and an interface module 14. The display module 12 may include a data driver and a display unit for providing data display. In some embodiments, the interface module 14 may include a deserializer to convert serial data into parallel data to accelerate data processing at the display 10. It should be understood that this is merely exemplary. The interface module may include other interfaces depending on the display's protocol.

The microprocessor 22 may generate data that can be displayed on the display 10 and provide the data to be displayed to the display 10 via the interface module 24. In some embodiments, the interface module 24 may include a serializer to convert data into serial data for data transmission. The interface module 14 of the display 10 may be coupled to the interface module 24 of the controller 20 to enable data communication. It should be understood that this is merely exemplary; the interface module may include other interfaces depending on the display's protocol. In some embodiments, the display 10 may also obtain electrical power from and be powered by the controller 20, which is particularly suitable for displays with lower power consumption. Since the display 10 and the controller 20 are well known to those skilled in the art, detailed descriptions of them are omitted, and the focus is placed on the interface between the display 10 and the controller 20.

[0036] The following is combined Figures 3a-6 The structure of a connector according to an embodiment of the present disclosure is described. Connector 30 may include a first connector 40 and a second connector 50. Figures 3a-3b A schematic diagram of the overall structure of the first connector 40 and the second connector 50 according to an embodiment of the present disclosure is shown.

[0037] like Figures 3a-3b As shown, the first connector 40 may be in the form of a socket. In the illustrated embodiment, the first connector 40 includes a circular circumferential wall 42 and a recess 44 surrounded by the circumferential wall 42. The recess 44 may be provided with a plurality of socket 46 contacts to receive the pin 56 contacts of the second connector 50. The second connector 50 may be in the form of a plug. In the illustrated embodiment, the second connector 50 includes a base 54 and pin 56 contacts extending from the base 54. The base 54 is adapted to mate with the shape of the recess 44, and with the base 54 received in the recess 44, the pin 56 can mate with the socket 46 to form an electrical interface.

[0038] In the illustrated embodiment, the first connector 40 is formed as a socket, and its contacts are formed as sockets 46; the second connector 50 is formed as a plug adapted to be received by the socket, and its contacts are formed as pins 56. It should be understood that this is merely exemplary, and the first connector 40 and the second connector 50 can be interchanged and implemented according to embodiments of this disclosure. Similarly, although in the illustrated embodiment, the circumferential wall 42 is shown as circular, the recess 44 is formed as rectangular, and the base 54 is formed as rectangular, these shapes are merely exemplary, and any other suitable shapes may be used. Furthermore, in the illustrated embodiment, the sockets 46 and pins 56 are formed as square; these are merely exemplary, and any other suitable shapes may be used.

[0039] In some embodiments, the first connector 40 may be part of the display 10, for example, the first connector 40 may be integrated into the display 10. In other embodiments, the first connector 40 may be attached to the display 10 via an adapter or a suitable cable. Similarly, the second connector 50 may be part of the controller 20, for example, the second connector 50 may be integrated into the controller 20. In other embodiments, the second connector 50 may be attached to the controller 20 via an adapter or a suitable cable.

[0040] In the illustrated embodiment, the first connector 40 and the second connector 50 are configured with 9 pins. It should be understood that the number of pins is merely exemplary and other numbers of pins may also be used. It is worth noting that in... Figures 3a-6 In the embodiments described herein, a 9-pin interface structure is used as an example to illustrate the inventive concept according to the embodiments of this disclosure. Based on the teachings of this disclosure, the inventive concept of the embodiments of this disclosure can be similarly applied to interface structures with other pins.

[0041] Figure 4 A contact interface definition diagram of a first connector head 40 of a connector according to an embodiment of the present disclosure is shown. Figure 5a and Figure 5b Schematic diagrams of the detection circuit and contact interface of the first connector 40 of the connector according to embodiments of the present disclosure are shown respectively. Figure 6 A schematic diagram of the contact interface of the second connector head 50 of a connector according to an embodiment of the present disclosure is shown. It is worth noting that, although... Figure 4 Only the distribution of each contact of the contact interface of the first connector 40 is shown. For the purpose of simplification, the distribution of each contact of the contact interface of the second connector 50 is not shown. However, considering that the first connector 40 and the second connector 50 form an interface circuit, the distribution of each contact of the contact interface of the second connector 50 can be easily obtained based on the contact interface definition diagram of the first connector 40.

[0042] like Figure 4 , Figure 5a , Figure 5b As shown, the first connector 40 includes a pair of first directional contacts DETEC_1 and second directional contacts DETEC_2 arranged in a row. Figure 6 As shown, the second connector 50 includes a detection contact DETEC.

[0043] In some embodiments, when the first connector 40 mates with the second connector 50 in a first mounting orientation, the detection contact DETEC connects with the first oriented contact DETEC_1 to provide a first potential at the first oriented contact DETEC_1; when the first connector 40 mates with the second connector 50 in a second mounting orientation opposite to the second mounting orientation, the detection contact DETEC connects with the second oriented contact DETEC_2 to provide a second potential different from the first potential.

[0044] Therefore, by setting a first directional contact DETEC_1 and a second directional contact DETEC_2, and forming a detection circuit with the detection contact DETEC, when the display 10 is mounted relative to the controller 20 with a first mounting orientation, the detection contact DETEC can acquire a first potential at the first directional contact DETEC_1; when the display 10 is mounted relative to the controller 20 with the opposite second mounting orientation, the detection contact DETEC can acquire a second potential at the first directional contact DETEC_1. Since the first potential and the second potential are different from each other, the mounting orientation of the display 10 can be easily determined, and the data displayed by the display 10 can be adjusted based on the mounting orientation to ensure correct data display.

[0045] In some embodiments, the first directional contact DETEC_1 and the second directional contact DETEC_2 may be arranged outside the geometric center of the first connector 40 and rotationally symmetrical with respect to the geometric center of the first connector 40. The detection contact DETEC may be configured at a position matching one of the first directional contact DETEC_1 and the second directional contact DETEC_2. In this case, the structure of the directional circuit can be simplified.

[0046] Specifically, for example, potential detection can be achieved by setting only one detection contact DETEC. Furthermore, since the first directional contact DETEC_1 and the second directional contact DETEC_2 can be arranged outside the geometric center of the first connector 40 and are arranged rotationally symmetrically with respect to the geometric center of the first connector 40, this ensures that the first directional contact DETEC_1 and the second directional contact DETEC_2 can characterize the orientation of the display 10, and regardless of the orientation of the display 10, it ensures that one of the first directional contact DETEC_1 and the second directional contact DETEC_2 is always detected by the detection contact DETEC.

[0047] In some embodiments, the first potential may be a high potential, and the second potential may be a potential different from the first potential. In some embodiments, the second potential may be a ground potential, in which case the circuit structure can be further simplified.

[0048] In some embodiments, such as Figure 5a As shown, the detection circuit includes a voltage divider resistor R1, and a first directional contact DETEC_1 and a second directional contact DETEC_2 are coupled to two different nodes P1 and P2 of the detection circuit of the first component 10. Thus, the arrangement of the detection circuit can be easily achieved using a single resistor.

[0049] In some embodiments, such as Figure 4 and Figure 5b As shown, the first connector 40 may include a ground contact GND. The ground contact GND is connected to one of the two nodes P2. The first connector 40 may include a pair of power contacts VCC_INPUT and VCC_INPUT. Figure 6 As shown, similar to the first connector 40, the second connector 50 may include a ground contact GND adapted to be connected to the ground of the controller 20. The second connector 50 may include paired power contacts VCC_OUTPUT and VCC_OUTPUT, which are connected, for example, to the power module of the controller 20 and adapted to draw power from the power supply. When the display 10 mates with the controller 20, one of the power contacts VCC_INPUT and VCC_INPUT of the first connector 40 mates with a corresponding power contact of the power contacts VCC_OUTPUT and VCC_OUTPUT in the second connector 50, thereby providing power to the power contact VCC_INPUT of the first connector 40. Specifically, as... Figure 5a As shown, the detection circuit formed by the power contact VCC_INPUT, the ground contact GND, and the voltage divider resistor R1 can conveniently detect the potential of nodes P1 and P2.

[0050] In some embodiments, such as Figure 4As shown, the ground contact GND of the first connector 40 is located at the geometric center of the first connector 40, and the power contacts VCC_INPUT and VCC_INPUT of the first connector 40 are arranged in pairs and rotationally symmetrical with respect to the geometric center of the first connector 40. This further reduces the number of contacts and simplifies the connector structure. It is worth noting that this is merely exemplary. In other embodiments, the power contacts of the first connector 40 are located at the geometric center of the first connector 40, and the ground contacts of the first connector 40 are arranged in pairs and rotationally symmetrical with respect to the geometric center of the first connector 40.

[0051] In some embodiments, such as 4 and Figure 5b As shown, the first connector 40 may further include two pairs of signal contacts SERDES_N and SERDES_P arranged in pairs. These two pairs of signal contacts SERDES_N and SERDES_P are arranged at a position outside the geometric center of the first connector 40 and are rotationally symmetrical with respect to the geometric center of the first connector 40, so that when the first connector 40 is installed in a first mounting orientation or a second mounting orientation, a communication connection is established with the second connector 50.

[0052] Figure 7a and Figure 7b Schematic diagrams of the structure of the first connector and the second connector according to another embodiment of the present disclosure are shown. Figure 8 It shows that according to Figure 7a The diagram shows the contact interface definition of the first connector in the illustrated embodiment. Figures 7a-8 Implementation examples and Figures 3a-6 The embodiments are similar, except that the first connector 40 and the second connector 50 are formed as a 16-pin structure.

[0053] like Figures 7a-8 As shown, the first connector 40 is formed as a socket, and its contacts are formed as sockets 46; the second connector 50 is formed as a plug suitable for reception by the socket, and its contacts are formed as pins 56. The dimensions of the plug and socket can be adapted to the number of contacts. Figures 3a-6 The difference in the embodiments is that the first connector 40 and the second connector 50 may include more extension contacts RES to further expand the functionality of the connector. Considering the... Figures 3a-6 The embodiments are similar, and detailed descriptions thereof are omitted.

[0054] exist Figure 8In the illustrated embodiment, the first connector 40 includes a pair of first directional contacts DETEC_1 and second directional contacts DETEC_2. The first directional contacts DETEC_1 and the second directional contacts DETEC_2 may be arranged at a location outside the geometric center of the first connector 40 and are rotationally symmetrical with respect to the geometric center of the first connector 40.

[0055] exist Figure 8 In the illustrated embodiment, the first connector 40 may include a ground contact GND and a pair of power contacts VCC. The ground contact GND of the first connector 40 is located at the geometric center of the first connector 40, and the power contacts VCC of the first connector 40 are arranged in pairs and are rotationally symmetrical with respect to the geometric center of the first connector 40.

[0056] exist Figure 8 In the illustrated embodiment, the first connector 40 may further include two pairs of signal contacts SERDES_N and SERDES_P arranged in pairs. These two pairs of signal contacts SERDES_N and SERDES_P are arranged at a position outside the geometric center of the first connector 40 and are rotationally symmetrical with respect to the geometric center of the first connector 40.

[0057] In addition, Figure 8 In the illustrated embodiment, the first connector 40 further includes a plurality of extension contacts RES for further expanding the functionality of the connector.

[0058] It is worth noting that the first directional contact DETEC_1, the second directional contact DETEC_2, the ground contact GND, the paired power contacts VCC and VCC, and the paired signal contacts SERDES_N and SERDES_P are merely illustrative examples. Based on the teachings of this disclosure, those skilled in the art can conceive of other possible arrangements of the contacts, which are also covered within the spirit of this disclosure.

[0059] Figure 9 A flowchart of a connector mounting orientation detection method 900 according to an embodiment of the present disclosure is shown. Figure 9 As shown, method 900 includes: at 902, acquiring a detection potential from the detection contact DETEC of the second connector 50; and at 904, determining the mounting orientation of the first component (10) based on the detection potential.

[0060] In some embodiments, the decision to issue an alarm signal may be based on the determined installation orientation of the display 10. For example, in some cases, if it is determined that the display 10 is improperly installed, a visual or audible alarm signal may be issued to prompt the user to reinstall it.

[0061] In some embodiments, method 900 further includes: at 906, in response to an acquired detection potential equal to a first potential, providing a data signal to display 10 in a first sequence to cause display 10 to display data in a predetermined normal mode. At 908, in response to an acquired detection potential equal to a second potential, providing a data signal to display 10 in a second sequence different from the first sequence to cause display 10 to display data in a predetermined normal mode. Thus, normal data display can be provided regardless of the mounting orientation of display 10.
