Description

Technical Field

[0001] This utility model relates to the technical field of connecting wire testing, and in particular to a male-to-male testing fixture. Background Technology

[0002] Monitor cables are crucial for connecting a computer (or other video output device) to a monitor. With the rapid development of display technology, monitor resolution, refresh rate, and color depth continue to improve (e.g., 8K@120Hz, HDR10+), leading to an exponential increase in the demand for data transmission bandwidth and stability. As a key transmission channel between the host and the display device, the performance of the monitor cable directly affects the integrity of the visual experience. Common types of data cables include HDMI cables, VGA cables, and DP cables.

[0003] Currently, after the monitor cable is manufactured, it needs to be tested to ensure that it can transmit signals normally. However, the current testing method is to connect both ends of the monitor cable to the host and the screen respectively, and test whether the host can transmit signals to the screen through the monitor cable. If the screen lights up normally, it means that the monitor cable is normal. However, after repeated testing, the interface between the host and the screen is easily damaged due to the repeated plugging and unplugging of the cable, resulting in inaccurate test results. This causes qualified cables to be judged as unqualified. Therefore, the interface needs to be replaced after a certain number of tests. However, the current testing method requires manually recording the number of tests, which is quite cumbersome. Utility Model Content

[0004] In order to automatically record the number of times the monitor connection cable is plugged in and unplugged, this utility model provides a male-to-male test fixture to address the problems of the prior art.

[0005] This utility model provides a male-to-male testing fixture, which adopts the following technical solution:

[0006] A male-to-male test fixture includes a base, a printed circuit board (PCB) mounted on the base, a controller mounted on the PCB, a power supply interface mounted on the PCB, a relay mounted on the PCB, two connection cable interfaces mounted on the PCB, two test machine interfaces mounted on the PCB, and a display screen mounted on the PCB. The two ends of a display cable are respectively plugged into the two connection cable interfaces. Both test machine interfaces are connected to a test machine, which transmits signals to the connection cable interfaces through the test machine interfaces. A sensor is mounted on the PCB. When the sensor detects that the display cable is plugged into the connection cable interface, the sensor sends a signal to the controller, and the controller transmits a signal to the display screen for counting.

[0007] Preferably, the printed circuit board is provided with a power supply switch, and when the switch is closed, the printed circuit board is powered on.

[0008] Preferably, the printed circuit board is provided with a display screen, and the display screen is electrically connected to the printed circuit board.

[0009] Preferably, the power supply interface is a Type-C interface.

[0010] Preferably, the sensing element includes a photoelectric sensor disposed on a printed circuit board, and an opening is provided on the side wall of the connection interface, with the sensing end of the photoelectric sensor facing the opening.

[0011] Preferably, the sensing element includes a mechanical switch disposed within the connection cable interface. The mechanical switch is electrically connected to the printed circuit board. When the connector is plugged into the connection cable interface, the connector presses down on the mechanical switch to close it. When the connection cable is disconnected from the connection cable interface, the mechanical switch is opened.

[0012] Preferably, the printed circuit board is provided with LED beads, and the LED beads light up when the display connection cable is plugged into the connection cable interface.

[0013] Preferably, the connector is one of a DP interface, an HDMI interface, or a VGA interface.

[0014] Preferably, the base is provided with a housing, and the housing is provided with multiple through holes, the positions of which correspond to the power supply interface, the connection cable interface and the test machine interface, respectively.

[0015] In summary, this utility model includes at least one of the following beneficial technical effects of male-to-male test clips:

[0016] 1. The operator plugs both ends of the monitor cable into the two connectors. The tester then transmits the current signal through the printed circuit board to the connector via the signal cable. After passing through the monitor cable, the current signal is returned to the tester from the other connector. This completes the test of the monitor cable.

[0017] 2. Each time the display cable is inserted into the connector interface, the mechanical switch and photoelectric sensor send a signal to the controller, the controller sends a signal to the display screen, and the display screen counts the number of tests, so that the operator can know the number of tests. When the number of times the connector is inserted into the connected interface is recorded to 10,000 times, the connection between the cable interface and the test machine interface is disconnected, and the service life of the cable interface is terminated.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] In the description of this application, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, or the orientation or positional relationship commonly used when the product is in use. These terms are used only for the convenience of describing this application and for simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application. Furthermore, the terms "first," "second," and "third," etc., are used only to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0028] Example 1: Example 1 of this utility model discloses a male-to-male test fixture, such as... Figure 1-5 As shown, it includes a base 1, which is made of phenolic plastic, also known as bakelite. A printed circuit board 2 is provided on the upper surface of the base 1. The printed circuit board 2 is fixedly connected to the base 1 by multiple bolts. A controller is provided on the printed circuit board and is electrically connected to the printed circuit board.

[0029] The printed circuit board 2 is equipped with a power supply interface 21, which is electrically connected to the printed circuit board 2. A relay 22 is also provided on the printed circuit board 2, and is electrically connected to both the printed circuit board 2 and the power supply interface 21. When the operator plugs the power cord into the power supply interface 21, the power cord supplies power to the printed circuit board 2. The relay 22 enhances safety. Furthermore, the power supply interface 21 is a Type-C interface, which is readily available, inexpensive, and highly compatible. Additionally, the printed circuit board 2 is equipped with a power switch 25. When the operator presses the switch, the printed circuit board 2 is powered on; pressing the switch again de-energizes the printed circuit board 2. This allows for convenient power disconnection when not in use for testing.

[0030] In addition, the printed circuit board 2 is provided with two connection cable interfaces 23. In this embodiment, the connection cable interface 23 is a DP interface. The connection cable interface 23 is electrically connected to the printed circuit board 2. The two ends of the display connection cable are respectively plugged into the two connection cable interfaces 23. The printed circuit board 2 is provided with two test machine interfaces 24, which are electrically connected to the printed circuit board 2. Both test machine interfaces 24 are connected to a test machine. The test machine is connected to two signal lines, which are respectively plugged into the two test machine interfaces 24. During testing, the operator plugs the two ends of the display connection cable into the two connection cable interfaces 23. Then the test machine transmits the current signal through the signal lines to the connection cable interface 23 via the printed circuit board 2. After passing through the display connection cable, the current signal is returned to the test machine from the other connection cable interface 23. This completes the test of the display connection cable.

[0031] In addition, the printed circuit board is equipped with sensors. Specifically, the sensors include a photoelectric sensor 27 disposed on the printed circuit board 2, which is electrically connected to the printed circuit board 2. An opening is provided on the side wall of the connection interface 23, and the sensing end of the photoelectric sensor 27 faces the opening. The sensors also include a mechanical switch 29 disposed within the connection interface 23. The mechanical switch 29 can be a tactile switch or a spring-loaded switch, and is electrically connected to the printed circuit board 2. When the connector is plugged into the connection interface 23, the connector presses the mechanical switch 29, causing it to close. When the connection cable is disconnected from the connection interface 23, the mechanical switch 29 springs back and opens. When the display connection cable is plugged into the connection interface 23, the photoelectric sensor senses the display connection cable, and simultaneously the mechanical switch 29 closes. The photoelectric sensor and the mechanical switch 29 closure generate an electrical signal, which is transmitted to the controller. These two signals are recognized as a single electrical signal by the main controller. Meanwhile, a display screen 26 is installed on the printed circuit board 2. The display screen 26 is electrically connected to the printed circuit board 2. When the photoelectric sensor and mechanical switch 29 transmit electrical signals to the controller, the controller sends a signal to the display screen to count and display the count. The display screen counts once when the display cable is plugged into the connector, allowing the operator to know the number of times the display cable has been plugged into and unplugged. When the number of times the connector has been plugged into the connector is recorded to 10,000, the connection between the connector and the test machine interface is disconnected, and the service life of the connector is terminated. The mechanical switch 29 and the photoelectric sensor 27 are mutually redundant. Only the mechanical switch, only the photoelectric sensor 27, or both can be installed for greater accuracy.

[0032] In addition, LEDs are installed on the printed circuit board and are electrically connected to the board. When the monitor cable is plugged into the connector, the LEDs light up. This allows the operator to determine whether the monitor cable is properly connected to the connector 23.

[0033] In addition, a housing 3 is provided on the base 1. The housing 3 can be made of transparent plastic and has multiple through holes 31. The positions of the multiple through holes 31 correspond to the power supply interface 21, the connection cable interface 23, the test machine interface 24, and the switch and display screen 26, respectively. The housing 3 can cover the printed circuit board 2, thereby preventing the printed circuit board 2 from being damaged.

[0034] The implementation principle of the male-to-male test fixture of this utility model is as follows: During testing, the operator plugs both ends of the display connection cable into the two connection cable interfaces 23. Then, the test machine transmits the current signal through the printed circuit board 2 to the connection cable interface 23 via the signal line. After passing through the display connection cable, the current signal is returned to the test machine from the other connection cable interface 23, thus completing the test of the display connection cable. Each time the display connection cable is inserted into the connector interface, the mechanical switch and photoelectric sensor send a signal to the controller, the controller sends a signal to the display screen, and the display screen counts the number of tests, allowing the operator to know the number of tests. When the number of times the connector is inserted into the connected interface 23 is recorded to 10,000, the connection between the connection cable interface and the test machine interface is disconnected, and the service life of the connection cable interface is terminated.

[0035] Example 2 differs from Example 1 in that, referring to... Figure 6 The connector 23 is an HDMI connector.

[0036] Example 3 differs from Example 1 in that, referring to... Figure 7 The connector 23 is a VGA connector.
