Example one

For convenience of understanding, please refer to fig. 1, which illustrates a schematic diagram of a socket detection apparatus in an embodiment of the present invention, for detecting a contact state between a male socket 12 and a female socket 11 of an aviation socket in a dynamic environment, and further determining whether the male socket 12 and the female socket 11 are in good contact. Referring to fig. 1, a first embodiment of the present invention provides a socket detection method, including the following steps:

assembling: the operation test piece 31 is connected with the power supply 50 through an aviation socket, a first resistor 32 is connected in series on a connecting loop of the operation test piece 31 and the power supply 50, and the oscilloscope 41 is connected in parallel on the first resistor 32;

the testing steps are as follows: and (3) turning on the oscilloscope 41, switching on the power supply 50, striking the socket male 12 in the aviation socket, observing the change of the current image on the oscilloscope 41 and recording.

For convenience of description, the display component is described by taking the oscilloscope 41 as an example, and the visible electrical signal displayed by the oscilloscope is a current image. The voltage collected by the first channel of the oscilloscope 41 forms a current image as a first current image, and the voltage collected by the second channel of the oscilloscope 41 forms a current image as a second current image.

Specifically, the operation test piece 31 is connected with the male socket head 12 of the aviation socket, the power supply 50 is connected with the female socket head 11 of the aviation socket, the first resistor 32 is connected with the operation test piece 31 in series, a current connection loop is further formed, and the current flowing through the first resistor 32, the current flowing through the operation test piece 31 and the current flowing through the aviation socket are the same. The first channel of the oscilloscope 41 is connected in parallel with the first resistor 32, so that the first channel of the oscilloscope 41 can input a voltage signal at two ends of the first resistor 32, and according to ohm's law, the oscilloscope 41 can convert the voltage signal into a current signal, and the current signal is displayed on the oscilloscope 41 in a first current image manner, so that an operator can observe and record the current signal conveniently.

The connection loop is further provided with a switch 60, when the switch 60 is closed, the connection loop is conducted, current passes through the connection loop, and when the switch 60 is disconnected, no current passes through the connection loop. The provision of the switch 60 facilitates operator control of the opening and closing of the connection circuit. When the oscilloscope 41 is used, the oscilloscope 41 needs to be connected with an oscilloscope power supply to ensure that the oscilloscope 41 is powered on and started.

In actual use, after the oscilloscope 41 is turned on, the switch 60 is closed, and the current flows through the connection loop. At this time, the socket male 12 is hit, and it is checked whether the first current image on the oscilloscope 41 changes due to the hitting frequency of the socket male 12. If the first current image on the oscilloscope 41 changes while the socket male 12 is being hit, it indicates that the current flowing through the first resistor 32 changes under the action of the hit, that is, the hit to the socket male 12 causes the socket male 12 to loosen relative to the socket female 11, for example: when the socket is hit, the male socket head 12 is disconnected from the female socket head 11, and no current passes through the socket; when the socket is not hit, the socket male head 12 and the socket female head 11 are electrically connected, and current passes through the socket male head 12 and the socket female head 11, namely poor contact is achieved. If the first current image on the oscilloscope 41 does not change while the male socket 12 is hit, that is, the hitting of the male socket 12 does not cause the male socket 12 to loosen relative to the female socket 11, i.e., the male socket 12 makes good contact with the female socket 11.

The socket monitoring method is mainly used for detecting the contact state of the aviation socket in a dynamic environment, namely the aviation socket is connected to a part needing to be operated, namely the operation test piece 31. In the normal working process of the operation test piece 31, an external force is applied to the male socket head 12, and the influence of the external force on the contact between the male socket head 12 and the female socket head 11 is judged through a first current image displayed by the oscilloscope 41, so that the operation is simple and convenient. Meanwhile, the reason why the operation test piece 31 fails in the dynamic environment can be effectively judged by the method, namely: the failure of the operation test piece 31 is caused by poor contact between the socket male head 12 and the socket female head 11 or the defect of the operation test piece 31 itself. If the contact is caused by poor contact of the aviation socket, the contact can be directly observed according to a first current image on the oscilloscope 41 under the condition of hitting the male plug 12 of the socket. If the fault is caused by the self-defect of the operation test piece 31, the aviation socket is in good contact, and the first current image displayed by the oscilloscope 41 does not change when the socket male head 12 is hit.

After the oscilloscope 41 is turned on, the sampling rate of the oscilloscope 41 needs to be adjusted, so that the oscilloscope 41 can use the voltage across the electromagnet 211 and the first resistor 32. Generally, when the sampling rate is adjusted to be high, the acquisition is more convenient.

In actual use, the electromagnetic induction of the electromagnet 211 can be used to strike the male receptacle 12, that is: the magnetic field generated by the electromagnet 211 after being electrified can drive the striking block 223 to move along the direction close to the socket male 12, so as to strike the socket male 12.

Specifically, the electromagnet 211 is connected to the power supply 50, and a second resistor is connected in series to a connection loop connecting the electromagnet 211 to the power supply 50, that is: the second resistor, the electromagnet 211 and the power source 50 are connected to form a second current loop, and when the electromagnet 211 is energized, an induced magnetic field is generated as power for driving the striking block 223 to move. The second resistor is arranged to facilitate adjustment of the current flowing through the electromagnet 211, thereby achieving adjustment of the magnitude of the induced magnetic field of the electromagnet 211. Meanwhile, the operation test piece 31, the first resistor 32, the aviation socket and the power supply 50 are connected to form a first current loop, and the first current loop and the second current loop are arranged in parallel. That is, when the switch 60 is turned on, the current output from the positive pole of the power source 50 can be transmitted in both directions, i.e., along the second current loop and the first current loop, and finally flow to the negative pole of the power source 50 in a combined manner. In this case, the induced magnetic field generated by the electromagnet 211 can cause the striking block 223 to move in a direction close to the male socket 12 and to collide with the male socket 12, so as to strike the male socket 12, and to observe the change of the first current image displayed on the oscilloscope 41.

In some embodiments, the second channel of the oscilloscope 41 is connected in parallel with the electromagnet 211. This arrangement facilitates detection of the voltage across the electromagnet 211 by the oscilloscope 41, and converts the voltage value into a current value by ohm's law, which is displayed as a second current image on the oscilloscope 41. In actual use, when the switch 60 is closed, the current passes through both the second current loop and the first current loop, and the first current image and the second current image can be displayed on the oscilloscope 41. When the male receptacle 12 is struck, a change in the first current pattern is judged. When the switch 60 is turned off, the change in the second current image is observed. That is, the number of times the switch 60 is interrupted and closed can be determined by observing the second current image to facilitate recording of the detection process.

Example two

Referring to fig. 1, fig. 1 is a schematic diagram illustrating a socket detection device according to an embodiment of the present invention, and this embodiment provides a socket detection device capable of detecting a contact state between a male socket 12 and a female socket 11 in an aviation socket. The socket detecting device includes a power source 50, a detecting part, a striking part, and a display part. Wherein, the detection component and the display component can be connected with the power supply 50, the power supply 50 is used for providing electric energy for the operation of the socket monitoring device, and the power supply 50 is connected with the socket female head 11. The detection component is used for being connected with the socket male connector 12, and the detection component can be used as an electricity utilization structure communicated with the power supply 50 through the aviation socket, so that a dynamic detection environment is provided for the aviation socket. The striking member is used for striking the male plug 12 of the socket, and the contact state of the male plug 12 of the socket and the female plug 11 of the socket can be adjusted by striking the male plug 12 of the socket. The display component is used for displaying the electric signal (namely the first current image) flowing through the detection component, and further judging whether the change of the contact state between the socket male head 12 and the socket female head 11 causes the change of the current.

In actual use, the power supply 50 is turned on, causing current to flow to the sensing element, causing the sensing element to activate. If the current flowing through the male plug 12 and the female plug 11 of the socket is changed at the same time of the striking, the current flowing through the detecting member is changed. At this time, the first current image captured by the display component and flowing through the detection component changes, and then the contact failure between the socket male head 12 and the socket female head 11 is proved, namely: the impact action of the impact member on the male socket head 12 causes the male socket head 12 to loosen relative to the female socket head 11, so that the current has a sudden interruption of the moment. If the first current image captured by the display part and flowing through the detection part does not change while being hit, the contact between the socket male head 12 and the socket female head 11 is proved to be good, that is: the male socket head 12 is firmly connected with the female socket head 11, and even if the male socket head 12 bears the impact action, the male socket head 12 cannot loosen relative to the female socket head 11.

That is, the socket detection device applies the impact action to the male socket 12 through the impact component, and judges whether the impact action applied by the impact component causes the current change of the detection component through the change of the first current image displayed by the display component, so as to determine whether the male socket 12 is in good contact with the female socket 11, and realize the detection of the contact state of the aviation socket in a dynamic environment.

The display component includes an oscilloscope 41, and the oscilloscope 41 can convert the input voltage value into a current value by using ohm's law, and display the current value in a current image manner so as to be convenient for an operator to observe.

In some embodiments, the detection component includes an operational test piece 31 and a first resistor 32, and the operational test piece 31 is connected to the power supply 50 through the aviation socket to form a dynamic environment for detecting the aviation socket. The first resistor 32 is connected in series with the operation test piece 31, so that the current flowing through the first resistor 32 is the same as the current flowing through the operation test piece 31, i.e. the first resistor 32, the operation test piece 31, the aviation socket and the power supply 50 are connected to form a first current loop. The oscilloscope 41 is connected in parallel with the first resistor 32 through the first channel, so that the first channel of the oscilloscope 41 can input the voltage value at the two ends of the first resistor 32, and then the oscilloscope 41 converts the voltage value into a current value by using ohm's law and displays the current value in a first current image mode, so that an operator can obtain the current change flowing through the first resistor 32 through the first current image. For example, in the non-striking state, the first current image shows a current value of 5 amperes, and the first current image is a straight line; when the male plug 11 of the socket is hit, the current value displayed by the first current image suddenly drops to 0A, which indicates that the male plug 11 of the socket and the female plug 12 of the socket are in poor contact,

the first resistor 32 is a current-limiting resistor, so as to limit the magnitude of the current flowing through the first current loop, so as to determine the current value.

The socket male 12 can be hit manually by using an insulating rod, or by using a mechanical structure, or by using an electromechanical combination. To facilitate an understanding of the striking implementation, a detailed description of the striking member is provided below.

In some embodiments, the striking member includes an electromagnetic induction assembly coupled to the power source 50 and a striking assembly capable of proximal and distal movement relative to the electromagnetic induction assembly. Wherein, can magnetism inhale after the circular telegram of electromagnetic induction subassembly and hit the subassembly, and then the drive hits the subassembly and hits the public head 12 of socket of beating. That is to say, after the power supply 50 is switched on, the electromagnetic induction component can generate an induction magnetic field under the action of current, and then the striking component is magnetically attracted through the induction magnetic field, so as to realize the striking operation of the striking component relative to the socket male 12. Simultaneously, if when the electromagnetic induction subassembly does not have the current to pass through, hit the subassembly and just lose the magnetic attraction that the electromagnetic induction subassembly was applyed, hit the subassembly and can move the electromagnetic induction subassembly relatively to hit the subassembly to reply initial position.

Referring to fig. 1, in the present embodiment, the electromagnetic induction component includes an electromagnet 211 and a second resistor, the electromagnet 211, the second resistor 212 and the power source 50 are connected to form a second current loop, and the second current loop is connected in parallel with the first current loop. Wherein, this socket detection device still includes switch 60, and switch 60 is used for controlling the opening and closing of second electric current return circuit and first electric current return circuit, promptly: when the switch 60 is closed, the second current loop and the first current loop are conducted, and the current output by the anode of the power supply 50 can respectively pass through the second current loop and the first current loop and finally flow to the cathode of the power supply 50 in a combined manner. When the switch 60 is open, no current flows through the second current loop and the first current loop. The switch 60 is a push switch, and when the switch 60 is pressed, the switch 60 is closed, and after the switch 60 is released, the switch is opened.

The second resistor 212 is an adjustable resistor, and the magnitude of the current flowing through the second current loop can be changed by adjusting the resistance value of the second resistor 212, so as to adjust the magnitude of the induced magnetic field of the electromagnet 211, thereby controlling the striking force of the striking block 223 acting on the socket male 12.

With continued reference to fig. 1, in some embodiments, the second channel of the oscilloscope 41 is disposed in parallel with the electromagnet 211, so that the second channel of the oscilloscope 41 can input the voltage value at the two ends of the electromagnet 211, and then the oscilloscope 41 can obtain the current value corresponding to the voltage value, i.e. the current value flowing through the electromagnet 211, by using ohm's law, and display the current value in the form of a second current image, so as to be convenient for the operator to observe.

In actual use, the oscilloscope 41 is turned on, the sampling rate of the oscilloscope 41 is adjusted, and then the switch 60 is pressed to close the second current loop and the first current loop, so that the first current image and the second current image can be displayed on the oscilloscope 41. The electromagnet 211 generates an induction magnetic field in the process of electrifying, so that the suction block 221 drives the striking block 223 to strike the socket male 12, and whether the first current image changes or not is observed. Then, the switch 60 is released, no current passes through the second current loop and the first current loop, the electromagnet 211 cannot generate an induction magnetic field, and the striking block 223 is driven by the suction block 221 to return to the initial position. At this time, the second current image displayed on the oscilloscope 41 changes, and the current finger drops to 0 ampere, so that the number of times of the energizing impact of the electromagnet 211 is conveniently recorded. That is, each time the switch 60 is pressed, the impact block 223 can impact the male receptacle 12 once, and the second current image on the oscilloscope 41 changes once.

With reference to fig. 1, preferably, the striking assembly includes a suction block 221, a connecting rod 222 and a striking block 223, the connecting rod 222 is slidably connected to the electromagnet 211, one end of the connecting rod 222 is fixedly connected to the suction block 221, and the other end of the connecting rod 222 is fixedly connected to the striking block 223. After the electromagnet 211 is electrified, the attraction block 221 can be magnetically attracted, so that the attraction block 221 moves towards the direction close to the electromagnet 211, and at the moment, the striking block 223 synchronously moves along with the attraction block 221 under the action of the connecting rod 222, so that the striking block 223 can be close to the socket male 12, and striking on the socket male 12 is further realized.

Taking the example that the suction block 221 moves in the horizontal left-right direction, the following arrangement scheme is provided:

when the suction block 221 moves horizontally to the right, the suction block 221 is located at the left side of the electromagnet 211. At this time, when the electromagnet 211 is energized, the attraction block 221 can be magnetically attracted to move rightward, and the striking block 223 can move rightward in synchronization with the attraction block 221. If the socket male head 12 is positioned on the right side of the electromagnet 211, the striking block 223 is positioned between the electromagnet 211 and the socket male head 12, and the right movement of the striking block 223 can collide with the left side of the socket male head 12; if the receptacle male 12 is located on the left side of the electromagnet 211, the striking block 223 is located on the side of the receptacle male 12 away from the electromagnet 211, and the striking block 223 strikes the left side of the receptacle male 12.

When the suction block 221 is horizontally moved leftward, the suction block 221 is positioned at the right side of the electromagnet 211. At this time, when the electromagnet 211 is energized, the attraction block 221 can be magnetically attracted to move leftward, and the striking block 223 moves leftward in synchronization with the attraction block 221. Wherein, if the socket male 12 is located at the left side of the electromagnet 211, the striking block 223 is located between the electromagnet 211 and the socket male 12; if the receptacle male 12 is located on the right side of the electromagnet 211, the striking block 223 is located on the side of the receptacle male 12 remote from the electromagnet 211.

In any of the above-described embodiments, the attraction block 221 may be magnetically attracted by the induced magnetic field generated by the electromagnet 211, and the striking block 223 may strike the receptacle male 12.

The attraction block 221 is made of a material with good magnetism so as to facilitate magnetic attraction of the electromagnet 211, such as a magnet. The connecting rod 222 and the striking block 223 are made of non-magnetic materials, such as rubber and silica gel. Moreover, when the striking block 223 is made of a rubber material, the abrasion of the striking block 223 to the receptacle male 12 can be effectively reduced, while the insulating effect is mentioned.

With continued reference to fig. 1, in some embodiments, the striking assembly further includes an elastic member 224, one end of the elastic member 224 is fixed to the electromagnet 211, and the other end of the elastic member 224 is fixed to the suction block 221, and the elastic member 224 is configured to urge the suction block 221 to have a movement tendency of returning to an initial state.

Specifically, the elastic member 224 is a compression spring, and the elastic member 224 is sleeved on the outer side wall of the connecting rod 222. When the suction block 221 and the striking block 223 are respectively located at both sides of the electromagnet 211, the electromagnet 211 is provided with a mounting hole for the connection rod 222 to pass through, so as to realize the sliding connection of the connection rod 222 relative to the electromagnet 211. The electromagnet 211 magnetically attracts the attraction block 221 to compress the elastic member 224, thereby generating elastic potential energy. When the electromagnet 211 is powered off, the elastic potential energy of the elastic part 224 is converted into power potential energy, so that the suction block 221 is pushed to move in a direction away from the electromagnet 211, the suction block 221 automatically returns, and the striking block 223 synchronously moves along with the suction block 221.

Of course, the suction block 221 may be returned to the original position by manual operation of the operator after the electromagnet 211 is de-energized.

With continued reference to fig. 1, in some embodiments, the striking assembly further includes an adjusting sleeve 225, the adjusting sleeve 225 is disposed on the outer side of the connecting rod 222, and two ends of the connecting rod 222 respectively pass through the adjusting sleeve 225. When the adjusting sleeve 225 is rotated, the length of the first end distance adjusting sleeve 225 and the length of the second end distance adjusting sleeve 225 can be adjusted by using the first end of the connecting rod 222 connected with the suction block 221 as a first end and the second end of the connecting rod 222 connected with the striking block 223 as a second end.

In actual use, the adjusting sleeve 225 is screwed with the connecting rod 222. Specifically, the outer side wall of the connecting rod 222 is provided with an external thread, and the inner side wall of the adjusting sleeve 225 is provided with an internal thread, and the external thread is in threaded fit with the internal thread. For example, when the adjustment sleeve 225 is rotated clockwise about the axis of the connection rod 222, the first end gradually increases in length from the adjustment sleeve 225, and the second end gradually decreases in length from the adjustment sleeve 225; when the adjustment sleeve 225 is rotated counterclockwise about the axis of the connection rod 222, the first end gradually decreases in length from the adjustment sleeve 225, and the second end gradually increases in length from the adjustment sleeve 225.

Wherein the lengths of the first end and the second end from the adjusting sleeve 225 are adjusted according to the magnitude of the current flowing through the electromagnet 211. If the current value of the second current circuit is large, the induced magnetic field generated by the electromagnet 211 is large, and the magnetic attraction acting on the attraction block 221 is also large, so that the moving distance of the attraction block 221 with respect to the electromagnet 211 is large, and at this time, the distance from the striking block 223 to the receptacle male 12 needs to be increased by adjusting the adjusting sleeve 225. On the contrary, if the value of the current flowing through the second current loop is small, the induced magnetic field generated by the electromagnet 211 is small, and the magnetic attraction acting on the attraction block 221 is also small, so that the moving distance of the attraction block 221 relative to the electromagnet 211 is large, and at this time, the distance from the striking block 223 to the socket male 12 needs to be reduced by adjusting the adjusting sleeve 225. Meanwhile, the adjustment of the connecting rod 222 by the adjusting sleeve 225 is also related to the linear distance between the striking block 223 and the socket male 12, if the striking block 223 is closer to the socket male 12, the stroke of the connecting rod 222 is shorter, and if the striking block 223 is farther from the socket male 12, the stroke of the connecting rod 222 is longer.

It is supplementary to need, connecting rod 222 also can be by two body strokes that cup joint, and the bell and spigot joint department at two bodys is established to adjusting sleeve 225 cover, is provided with the helicitic texture when the inside wall of adjusting sleeve 225, and when adjusting sleeve 225 screwed to the body, the length is no longer changed to the cover between two bodys, and when adjusting sleeve 225 unscrewed to the body, the length can be changed to the cover between two bodys to be adapted to the stroke requirement of connecting rod 222. In either way, it is only necessary to adjust the stroke of the connecting rod 222.

With continued reference to fig. 1, in some embodiments, the striking member further includes a bracket assembly 23, the bracket assembly 23 being configured to mount the electromagnet 211 relative to the female receptacle 11. Specifically, bracket assembly 23 has a first mounting portion for connecting with socket female 11 and a second mounting portion for connecting with electromagnet 211, thereby ensuring that electromagnet 211 is reliably mounted with respect to the aviation socket.

In practical use, the bracket assembly 23 includes two clamps, the two clamps are a first clamp and a second clamp respectively, and the first clamp and the second clamp are connected through a connecting rod to form an integral structure. The first clamp is used as a first mounting part and clamps the female socket head 11; the second yoke acts as a second mounting portion to clamp the electromagnet 211. Wherein, first clamp and second clamp all adopt insulating material to make. Wherein the distance between the first and second bands is related to the stroke of the connecting rod 222, so that the stroke of the connecting rod 222 is adjusted by the adjusting sleeve 225.

Alternatively, the bracket assembly 23 may include two opposite fastening strips, and each of the two fastening strips is provided with a first groove and a second groove. When two card strips were detained mutually, two relative settings of first recess were as first installation department, and two relative settings of second recess were as the second installation department. The female socket 11 is clamped between the two first grooves, the electromagnet 211 is clamped between the two second grooves, and then the two clamping strips are fastened by using fasteners such as bolts. It is sufficient if the electromagnet 211 can be stably attached to the female socket head 11.
