Abstract
Description
Technical Field
[0001] This utility model relates to the field of precision instrument testing, and in particular to an electromagnetic separation testing device for a detached connector. Background Technology
[0002] With the continuous development of detachable connectors, manual mechanical separation has gradually been replaced by electromagnetic separation. Electromagnetic separation connectors add electromagnetic components to the mechanical separation connector. During electromagnetic separation, a specified electrical signal needs to be input into the electromagnetic component of the connector. The electromagnetic component operates, converting electromagnetic energy into mechanical energy, causing the two ends of the detachable connector to separate. However, due to the different construction of each detachable connector, the separation time varies during the electromagnetic separation process. Therefore, testing the electromagnetic separation time of detachable connectors has become an indispensable step.
[0003] In existing technologies, electromagnetic separation testing of detached connectors typically involves placing the detached connector horizontally on a test bench and connecting it to a circuit. After an electrical signal is applied, the time it takes for the circuit to disconnect is manually counted.
[0004] In existing electromagnetic separation testing devices for detached connectors, the detached connector is placed horizontally on the test bench, which means that the detached connector can only be separated by electromagnetic means. During the separation process, friction may occur between the connector and the workbench, resulting in insufficient separation. As a result, the measured separation time data is mostly invalid data, and repeated tests are required to obtain accurate test results, which leads to low testing efficiency. Furthermore, the accuracy is low because the time is measured by manual counting. Utility Model Content
[0005] This utility model provides an electromagnetic separation testing device for detached connectors, which solves the problems of low testing efficiency and low accuracy in the prior art. The technical solution is as follows:
[0006] An electromagnetic separation testing device for a detached connector includes: a base plate, a portal frame, a power supply, resistors, an oscilloscope, and the detached connector.
[0007] Two portal frames are provided, arranged parallel to each other on the base plate. A mounting plate is provided between the two portal frames. The power supply and the oscilloscope are mounted on the mounting plate. The power supply is equipped with a first switch.

The resistor is connected in parallel with the disconnected connector. The disconnected connector is located below the mounting plate. The disconnected connector includes a first terminal and a second terminal. The first terminal is located below the second terminal. A second switch is provided between the second terminal and the power supply.
[0008] Optionally, a connecting rod is provided between the two portal brackets, and the connecting rod is located at the top of the portal bracket.
[0009] Optionally, it also includes wires and a support frame, wherein the power supply, resistor, oscilloscope and disconnector are connected by wires, and the support frame is mounted on the connecting rod to provide support for the wires.
[0010] Optionally, a storage box is provided on the base plate, and the storage box is located between the two gate-shaped brackets, below the first terminal.
[0011] Optionally, a rubber mesh is provided inside the storage box.
[0012] Optionally, the bottom of the storage box is provided with a buffer mechanism, which includes a sliding rod, a sliding sleeve and a spring. The sliding sleeve is disposed on the base plate. One end of the sliding rod is fixed to the bottom of the storage box and the other end is slidably disposed inside the sliding sleeve. The spring is sleeved on the sliding rod and is located between the sliding sleeve and the storage box.

[0016] The beneficial effects of the technical solution provided by this utility model embodiment include at least the following:
[0017] This utility model provides an electromagnetic separation testing device for a detached connector. A resistor, oscilloscope, and the detached connector are mounted on a mounting plate. The resistor and the detached connector are connected in parallel, and the oscilloscope is connected in parallel across the resistor. When the first switch is closed, the circuit of the resistor is connected, and the voltage across the resistor can be measured using the oscilloscope. When the second switch is closed, the detached connector is connected in parallel to the circuit, and the voltage across the resistor changes as measured by the oscilloscope. After a period of time, the first and second terminals will detach, breaking the circuit of the detached connector. Due to gravity, the second terminal will more easily separate from the first terminal. The voltage across the resistor measured by the oscilloscope will change again. By recording the time difference between the two changes, the separation time of the detached connector can be measured. When it is necessary to measure the separation time of other detached connectors, simply replace the detached connector and connect it to the circuit. The separation time of the detached connector measured by this method is such that, due to the longitudinal arrangement of the first and second terminals, the detached connector will not be unable to separate due to interference from the external environment or components. This can reduce the testing time, improve testing efficiency, and the oscilloscope reading is more accurate. It can effectively solve the problems of low testing efficiency and low accuracy in the existing technology. Attached Figure Description

For example... Figures 1 to 5 An electromagnetic separation testing device for a detached connector includes: a base plate 1, a gate-shaped bracket 2, a power supply 3, a resistor 4, an oscilloscope 5, and a detached connector 6. Two gate-shaped brackets 2 are arranged parallel to each other on the base plate 1, and a mounting plate 21 is provided between the two gate-shaped brackets 2. The power supply 3 and the oscilloscope 5 are mounted on the mounting plate 21. A first switch 31 is provided on the power supply 3. The power supply 3 is electrically connected to the resistor 4 and the detached connector 6 respectively. The oscilloscope 5 is connected in parallel with the resistor 4, and the resistor 4 is connected in parallel with the detached connector 6. The detached connector 6 is located below the mounting plate 21. The detached connector 6 includes a first terminal 61 and a second terminal 62. The first terminal 61 is located below the second terminal 62, and a second switch 7 is provided between the second terminal 62 and the power supply 3.
[0027] For example, in this embodiment of the present invention, the power supply 3, resistor 4, oscilloscope 5 and disconnector 6 are all electronic components of the device, and they are all connected by wires 8. The power supply 3 is fixed on the mounting plate 21, and the resistor 4 and oscilloscope 5 are also fixed on the mounting plate 21. The detachable connector 6 is then fixed to the bottom of the mounting plate 21, so that the second terminal 62 is fixed to the bottom of the mounting plate 21, and the first terminal 61 is located below the second terminal 62. The power supply 3 and the resistor 4 are connected together to form a circuit through the wire 8. The oscilloscope 5 is connected in parallel across the two ends of the resistor 4. The positive terminal of the power supply 3 is connected to the first terminal 61 and the negative terminal of the power supply 3 is connected to the second terminal 62 through the wire 8. The second switch 7 is set between the second terminal 62 and the negative terminal of the power supply 3. First, the first switch 31 is closed to turn on the power supply 3, so that the resistor 4 is energized. At this time, the oscilloscope 5 can test the voltage across the resistor 4 and form a waveform. After the second switch 7 is closed, the detachable connector 6 is connected in parallel with the resistor 4 to the circuit. At this time, the voltage across the resistor 4 measured by the oscilloscope 5 will change, and the waveform formed on it will also change. After the detachable connector 6 is energized for a period of time, the first terminal 61 and the second terminal 62 separate. Because the first terminal 61 and the second terminal 62 are arranged longitudinally, the first terminal 61 has a high success rate of detachment under gravity and will not fail to separate due to external environmental factors or frictional resistance of the equipment. When the detached connector 6 disconnects the circuit, the voltage across the resistor 4 returns to its initial state. The oscilloscope 5 measures that the voltage across the resistor 4 changes again. By recording the time difference between the two waveform changes on the oscilloscope 5, the time required for the detached connector 6 to separate is determined. Connectors are provided at the connection points of the wire 8 with the first terminal 61 and the second terminal 62. Interfaces are provided on the first terminal 61 and the second terminal 62. Each detached connector under test has the same interface. By plugging in the connectors and interfaces, different detached connectors 6 can be quickly replaced for measurement, thereby improving testing efficiency.
[0028] This embodiment of the invention provides an electromagnetic separation testing device for a detached connector. A resistor 4, an oscilloscope 5, and a detached connector 6 are mounted on a mounting plate 21. The resistor 4 and the detached connector 6 are connected in parallel, and the oscilloscope 5 is connected in parallel across the resistor 4. When the first switch 31 is closed, the circuit of the resistor 4 is connected, and the voltage across the resistor 4 can be measured using the oscilloscope 5. When the second switch 7 is closed, the detached connector 6 is connected in parallel to the circuit, and the voltage across the resistor 4 changes as measured by the oscilloscope 5. After a period of time, the first terminal 61 and the second terminal 62 will detach, breaking the circuit of the detached connector 6. Due to gravity, the second terminal 62 will more easily separate from the first terminal. When the connector 61 separates, the voltage across resistor 4 measured by oscilloscope 5 will change again. By recording the time difference between the two changes, the separation time of the detached connector 6 can be measured. When it is necessary to measure the separation time of other detached connectors 6, simply replace the detached connector 6 and connect it to the circuit. The separation time of the detached connector 6 measured by this method is such that, due to the longitudinal arrangement of the first terminal 61 and the second terminal 62, the detached connector 6 will not be unable to separate due to interference from the external environment or components. This can reduce the testing time, improve testing efficiency, and the reading from oscilloscope 5 is more accurate. It can effectively solve the problems of low testing efficiency and low accuracy in the existing technology.
[0029] Optionally, a connecting rod 22 is provided between the two portal brackets 2, and the connecting rod 22 is located at the top of the portal bracket 2.
[0030] For example, in this embodiment of the present invention, by providing a connecting rod 22 between the two gate-shaped brackets 2, the connection between the two gate-shaped brackets 2 is made more stable, thereby enabling the mounting plate 21 to be more stably mounted on the gate-shaped brackets 2, and thus enabling the entire circuit structure to be stably mounted on the gate-shaped brackets 2, thereby improving the stability of the device.
[0031] Optionally, it also includes a wire 8 and a support frame 23. The power supply 3, resistor 4, oscilloscope 5 and disconnector 6 are connected by the wire 8. The support frame 23 is mounted on the connecting rod 22 to provide support for the wire 8.
[0032] For example, in this embodiment of the present invention, since the first terminal 61 will detach from the second terminal 62 after being energized for a period of time, the first terminal 61 will fall under the action of gravity. Therefore, the wire 8 between the first terminal 61 and the positive terminal of the power supply is a soft wire 8, which facilitates the free fall of the first terminal 61. The other wires 8 are made of rigid wires 8 in order to maintain the stability of the circuit. The rigid wires 8 are fixed and supported by the support frame 23 set on the connecting rod 22, so as to ensure the stability of the entire circuit and further improve the stability of the device.
[0033] Optionally, a storage box 9 is provided on the base plate 1, and the storage box 9 is located between the two gate-shaped brackets 2, below the first terminal 61.
[0034] For example, in this embodiment of the present invention, since the first terminal 61 will fall after it is detached, in order to prevent the falling first terminal 61 from colliding with other components and to provide protection for the first terminal 61, a storage box 9 is provided below it, thereby improving the service life of the device.
[0035] Optionally, a rubber mesh 91 is provided inside the storage box 9.
[0036] For example, in this embodiment of the present invention, by providing a rubber mesh 91 inside the storage box 9, the falling first terminal 61 can be prevented from colliding hard with the storage box 9. The rubber mesh 91 plays a buffering role against the falling of the first terminal 61, thereby further improving the service life of the device.
[0037] Optionally, the bottom of the storage box 9 is provided with a buffer mechanism 10. The buffer mechanism 10 includes a sliding rod 101, a sliding sleeve 102 and a spring 103. The sliding sleeve 102 is provided on the base plate 1. One end of the sliding rod 101 is fixed to the bottom of the storage box 9 and the other end is slidably provided inside the sliding sleeve 102. The spring 103 is sleeved on the sliding rod 101 and is located between the sliding sleeve 102 and the storage box 9.
[0038] Exemplary, in this embodiment of the present invention, when the first terminal 61 falls into the storage box 9, the downward force of the first terminal 61 can be buffered by the buffer mechanism 10 to prevent the first terminal 61 from colliding hard with the storage box 9. After the first terminal 61 falls into the storage box 9, the storage box 9 will move downward with the sliding rod 101, and the other end of the sliding rod 101 will also slide in the sliding sleeve 102, thereby compressing the spring 103 and counteracting the downward force of the storage box 9, thus preventing the storage box 9 from being damaged due to excessive force, thereby further improving the service life of the device.
[0039] Optionally, four buffer mechanisms 10 are provided, arranged in a rectangular array at the bottom of the storage box 9.
[0040] For example, in this embodiment of the present invention, by providing four buffer mechanisms 10 arranged in a rectangular array at the bottom of the storage box 9, the storage box 9 can be more stably placed on the buffer mechanisms 10, so that the storage box 9 will not tilt due to the downward force of the first terminal 61, thereby further improving the stability of the device.
[0041] Optionally, the door-shaped brackets 2 are provided with a sliding groove 24 on one side close to each other, and the storage box 9 is provided with a protrusion 92 that matches the sliding groove 24 on the side close to the door-shaped brackets 2. The protrusion 92 is slidably disposed in the sliding groove 24.
[0042] For example, in this embodiment of the present invention, the cooperation between the groove 24 and the protrusion 92 enables the storage box 9 to be buffered on the buffer mechanism 10, thereby providing a vertical guiding effect for the storage box 9 and preventing the storage box 9 from tilting due to uneven force, thus further improving the stability of the device.
[0043] Optionally, the bottom of the base plate 1 is provided with anti-slip pads 11, which are located at the four corners of the base plate 1.
[0044] For example, in this embodiment of the present invention, by providing an anti-slip pad 11 at the bottom of the base plate 1, the excessive downward force of the first terminal 61 can be prevented from causing the entire device to slide. The anti-slip pad 11 can be made of materials such as rubber, thereby increasing the friction between the device and the experimental table. By providing the anti-slip pad 11, the stability of the device is further improved.
