Description

Technical Field

[0001] This utility model relates to the technical field of audio socket testing devices, specifically a testing device for a XLR audio composite socket. Background Technology

[0002] As a key interface component for signal transmission in audio equipment, XLR audio composite sockets are widely used in professional audio, broadcasting, television, and stage performances. The stability of their electrical performance directly affects the quality of audio signal transmission. Due to the extremely high reliability requirements of these applications, the key performance indicators of XLR audio composite sockets, such as terminal conductivity and insulation, must be rigorously tested during the production process to ensure that product quality meets industry standards.

[0003] Currently, XLR audio composite sockets are divided into two types based on their structure: horizontal and vertical. The positive and negative terminals of the horizontal composite socket are located on the side, while those of the vertical composite socket are located on the bottom, resulting in a significant difference in terminal layout between the two types. In existing technology, testing these two types of sockets typically requires the design of dedicated testing devices: testing the horizontal socket requires a side-insertion testing structure adapted to the side terminals; testing the vertical socket requires a horizontal-insertion testing structure adapted to the bottom terminals.

[0004] This separate testing method has obvious drawbacks: on the one hand, it requires two independent testing devices, which not only increases the cost of equipment procurement and workshop floor space, but also requires separate maintenance and calibration of the two devices, thus increasing production and operating costs.

[0005] Therefore, developing a testing device that can simultaneously adapt to the detection of horizontal and vertical XLR audio composite sockets, has a compact structure, is easy to operate, and has a low cost has become an urgent technical problem to be solved in this field. Utility Model Content

[0006] In view of the shortcomings of the prior art, this utility model provides a XLR audio composite socket detection device.

[0007] The technical solution adopted by this utility model is: a XLR audio composite socket detection device, comprising: The cabinet has a cavity for accommodating components, a testing platform and a display platform on the front side of the cabinet, a mounting plate on the top of the cabinet, and a testing port on the testing platform. A plug driving assembly, comprising a plug driving cylinder fixed on a mounting plate, a plug connected to the output end of the plug driving cylinder, a pressing cylinder fixed on the mounting plate, and a pressing foot connected to the output end of the pressing cylinder. A socket fixture, wherein the socket fixture is provided with a fixing cavity for installing a composite socket, and a bottom pin is provided at the bottom of the fixing cavity to communicate with the fixing cavity; A side-pin assembly, located on the side of a socket fixture, includes a side-pin drive cylinder, a pin plate connected to the output end of the side-pin drive cylinder, and a side-pin disposed on the pin plate.

[0008] Furthermore, the side of the fixing cavity is provided with a clearance notch for the side insertion pin to extend into the fixing cavity.

[0009] Furthermore, the socket fixture is located in the cavity below the detection port, and the upper surface of the socket fixture is flush with the detection table surface.

[0010] Furthermore, one end of the presser foot has a pressing ring adapted to the composite socket, and the pressing ring is fitted onto the plug.

[0011] Furthermore, it also includes a spring detection assembly comprising a spring cylinder, an insulating plate, a spring pin, and a fixing pin. The output end of the spring cylinder is connected to the insulating plate. A sliding hole plate and a fixing plate are arranged parallel to each other on the insulating plate. The sliding hole plate and the fixing plate are respectively provided with sliding holes and fixing holes. The fixing pin is fixed on the fixing hole, and the spring pin is slidably connected to the sliding hole.

[0012] Furthermore, the plug drive cylinder, pressing cylinder, side pin drive cylinder, and spring cylinder are all connected to the PCL controller via solenoid valves.

[0013] On the other hand, the plug includes a microphone plug and a XLR connector.

[0014] The beneficial effects of this utility model are as follows: This application achieves the testing and adaptation of two different types of XLR audio composite sockets—horizontal and vertical—using an integrated structural design with side pin assemblies on the side and bottom pins on the bottom of the socket fixture.

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] It should be noted that if the embodiments of this utility model involve directional indicators (such as up, down, left, right, front, back, etc.), the directional indicators are only used to explain the relative positional relationship and movement of the components in a certain specific posture (as shown in the figure). If the specific posture changes, the directional indicators will also change accordingly.

[0026] This utility model provides a testing device for XLR audio composite sockets.

[0027] In this embodiment, refer to Figure 1-7The XLR audio composite jack detection device includes: The cabinet 1 has a cavity 2 for accommodating components. The front side of the cabinet 1 is provided with a test platform 3 and a display platform 4. The upper end of the cabinet is provided with a mounting plate 5. The test platform is provided with a test port 6. A plug driving assembly, comprising a plug driving cylinder 7 fixed on a mounting plate, a plug 8 connected to the output end of the plug driving cylinder 7, a pressing cylinder 9 fixed on the mounting plate, and a pressing foot 10 connected to the output end of the pressing cylinder. A socket fixture 11 is provided with a fixing cavity 12 for installing a composite socket, and a bottom pin 13 communicating with the fixing cavity 12 is provided at the bottom of the fixing cavity 12. A side-pin assembly is located on the side of a socket fixture. It includes a side-pin drive cylinder 14, a pin plate 15 connected to the output end of the side-pin drive cylinder 14, and a side-pin 16 disposed on the pin plate. PCL controller 17 and multiple solenoid valves 18, wherein the side pins, solenoid valves and bottom pins are all connected to the PCL controller; The side pin assembly is used to detect the side terminals of the horizontal composite socket, and the bottom pin is used to detect the bottom terminals of the vertical composite socket.

[0028] In the above technical solution, the plug drive assembly uses a plug drive cylinder to move the plug, achieving docking with the composite socket. A pressing cylinder drives the pressure foot to fix the socket, ensuring connection stability. The socket fixture's fixing cavity is used to position the composite socket. The bottom pin can contact the bottom terminal of the vertical socket (during testing, the vertical socket is placed directly and naturally docked with the bottom pin). The side pin assembly, under the action of the side pin drive cylinder, makes the side pin contact the side terminal of the vertical socket. The PLC controller controls the solenoid valve to coordinate the actions of each component, achieving the detection of both types of sockets.

[0029] The above technical solution integrates a detection structure compatible with both horizontal and vertical composite sockets, enabling a single device to test both types of sockets, reducing equipment investment and floor space requirements. Automated drive and control methods enhance the convenience and consistency of testing, improving efficiency and accuracy.

[0030] Specifically, the side of the fixed cavity is provided with a clearance notch 19 for the side insertion pin to extend into the fixed cavity.

[0031] In this embodiment, a clearance notch is provided on the side of the fixing cavity to provide a channel for the side pin to extend into the fixing cavity and contact the side terminal of the vertical composite socket, avoiding the obstruction of the side pin by the side wall of the fixing cavity and ensuring that the side pin can accurately and smoothly contact the side terminal.

[0032] Specifically, the socket fixture is located in the cavity below the detection port, and the upper surface of the socket fixture is flush with the detection table surface.

[0033] In this embodiment, the socket fixture is placed in the cavity below the detection port, and its upper surface is flush with the detection table surface. This allows the operator to place or remove the composite socket directly on the detection table surface without having to go into the cavity, while ensuring the stability of the socket fixture position.

[0034] Specifically, one end of the presser foot has a pressing ring 20 adapted to the composite socket, and the pressing ring 20 is fitted onto the plug.

[0035] In this embodiment, the pressing ring at one end of the presser foot is fitted onto the outside of the plug. When the pressing cylinder drives the presser foot downward, the pressing ring acts on the composite socket, firmly pressing it into the fixed cavity without affecting the connection between the plug and the socket. Furthermore, when the plug retracts, the pressing ring prevents workers from reaching into the socket to remove or place it, improving safety.

[0036] Specifically, it also includes a spring detection assembly comprising a spring cylinder 21, an insulating plate 22, a spring pin 23, and a fixing pin 24. The output end of the spring cylinder is connected to the insulating plate. A sliding hole plate 26 and a fixing plate 28 are arranged parallel to each other on the insulating plate. A sliding hole 29 and a fixing hole 30 are respectively provided on the sliding hole plate and the fixing plate. The fixing pin is fixed on the fixing hole, and the spring pin is slidably connected to the sliding hole.

[0037] In this embodiment, in the spring contact detection assembly, the spring contact cylinder drives the insulating plate to move, bringing the moving pin and the fixed pin close to the spring contact (terminal) of the composite socket. After the spring contact is touched, the spring pin retracts and contacts the fixed pin to conduct electricity, indicating that the spring contact has been correctly installed. When there is no spring contact, the spring pin will not retract and contact the fixed pin to conduct electricity, indicating that the spring contact is missing.

[0038] Specifically, the plug drive cylinder, pressing cylinder, side pin drive cylinder, and spring cylinder are all connected to the PCL controller via solenoid valves.

[0039] In this embodiment, each cylinder is connected to the PLC controller via a solenoid valve. The PLC controller can control the cylinder's movement by controlling the on / off state of the solenoid valve, thereby achieving precise control and coordinated operation of various aspects such as plug driving, pressing, side pin driving, and spring detection.

[0040] Specifically, the plug includes a microphone plug 32 and a XLR plug 33.

[0041] In this embodiment, the plug includes a microphone plug and a XLR plug, both of which match the corresponding interfaces on the composite socket. When the plug drive cylinder moves the plug to mate with the composite socket, the microphone plug and XLR plug can be simultaneously inserted into the corresponding interfaces of the composite socket. This allows for the acquisition of relevant detection signals for both the microphone and XLR interface functions of the composite socket in a single operation, achieving one-time testing of both functions without the need for two separate docking tests with different plugs. This reduces the steps and time required for testing, significantly improving testing efficiency and better meeting the testing needs of mass production. Furthermore, one-time docking reduces positioning errors that may result from multiple operations, improving the accuracy and stability of the testing.

[0042] The working principle of this application is as follows: The horizontal or vertical XLR audio composite socket 31 to be tested is placed into the fixed cavity of the socket fixture. The PLC controller controls the action of each cylinder through solenoid valves: the plug drive cylinder drives the plug to mate with the socket, and the pressing cylinder drives the pressing ring of the pressing foot to fix the socket. When testing a vertical socket, its bottom terminal contacts the bottom pin at the bottom of the fixed cavity; when testing a horizontal socket, the side pin drive cylinder pushes the side pin through the clearance notch to contact the side terminal. In the spring contact detection assembly, the spring contact cylinder drives the insulating plate to move, and the spring pin cooperates with the fixed pin to detect whether the spring contact is installed correctly. All detection signals are fed back to the PLC controller to complete the detection.

[0043] Attention all technical personnel: Although this utility model has been described according to the specific embodiments above, the concept of this utility model is not limited to this utility model. Any modification that utilizes the concept of this utility model will be included within the scope of protection of this patent right.
