[0026] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0027] The specific implementation of this utility model will be described in detail below with reference to specific embodiments.

[0028] like Figure 1 The diagram shown is a structural diagram of a detection device for a connector 3 provided in an embodiment of this utility model, comprising:

[0029] Detection element 2 is attached to the elastic element 1 and is used to detect the deformation of the elastic element 1 when the connector 3 is tightened or loosened.

[0030] Control module 4 is electrically connected to detection element 2 and is used for processing and outputting electrical signals generated by detection element 2.

[0031] In this embodiment of the utility model, preferably, the detection device for the connector 3 mainly consists of a detection element 2 and a control module 4. The connector 3 can be a bolt or nut, etc., and the elastic element 1 can be a washer, disc spring, etc., connected to the bolt or threaded sleeve and deforming when the connector 3 is tightened or loosened. The connector 3 can be inserted into the elastic element 1. The control module 4, which is electrically connected to the detection element 2, uses the detection element 2 installed on the elastic element 1 to detect the pressure generated by the elastic element 1 when the connector 3 is tightened or loosened, and transmits the detected signal and pressure change data to the control module 4. In this way, the connection of the connector 3 to the elastic element 1 can be detected. The stress value or stress change value generated by the compression of the first mounting hole of the elastic element 1 by the elastic element 1 is transmitted to the control module 4. The deformation of the elastic element 1 when the connecting part 3 is tightened or loosened is detected by the detection element 2 on the elastic element 1, and the generated electrical signal or signal data is transmitted to the control module 4 wirelessly or wiredly. When the detection element is attached to the elastic element, the signal is converted according to the electrical signal detected by the detection element. It can be the output voltage value, the output digital signal or the output pulse signal, so that it is directly converted and output by the control module or transmitted to the display device to be converted into a digital signal and then displayed on the display screen.

[0032] Preferably, during the detection process of the detection component 2, the pressure value range of the connector 3 under the tight state can be preset by the control module 4. When the connector 3 becomes loose, if the pressure value range detected by the detection component 2 deviates from the initial setting, the signal will be converted into a pulse signal to issue an alarm, which will help to indicate that the connector 3 is loose and needs to be repaired. Alternatively, the detected voltage value can be displayed by the display device of the control module 4 and viewed by the staff at any time, so that the staff can judge whether the connector 3 needs to be tightened. In this way, the tightness status of the connector 3 can be quickly determined. If it is loose, it is convenient for the staff to repair it. If it is not loose, there is no need for the staff to tighten it one by one, which saves time and effort and improves efficiency for the staff.

[0033] In one embodiment of this utility model, a detection element 2 is attached to the elastic element 1. The detection element 2 detects the deformation of the elastic element 1 when the connector 3 is tightened or loosened, and the resulting pressure generates an electrical signal. A control module 4 is electrically connected to the detection element 2 and transmits the electrical signal generated by the detection element to the control module 4, thereby obtaining the current connection status of the connector 3. The whole process is time-saving, labor-saving and highly efficient.

[0034] like Figure 1-5As shown, in a preferred embodiment of the present invention, the detection element 2 includes a first detection element 2 and a second detection element 2, which are arranged on the same test surface of the elastic element 1.

[0035] In this embodiment of the invention, preferably, the detection element 2 can be a patch-type pressure sensor. The detection element 2 is attached to the same measured surface of the elastic element 1 and arranged around the connection between the connector 3 and the elastic element 1. This allows the detection element 2 to be positioned on the same side of the connector 3 during detection, thereby detecting stress changes in the elastic element 1 on the same measured surface. This enables the acquisition of signals and data regarding pressure changes in the elastic element 1 when the connector 3 is tightened or secured. When the first and second detection elements 2 are used simultaneously, it can prevent displacement of the connector 3 during tightening or securing, while still accurately detecting pressure changes in the elastic element 1. In actual testing operations, when tightening or securing, it is impossible to guarantee that the position will not shift, resulting in uneven force at the connection with the elastic element 1. To avoid inaccurate test results, the test element 2 is connected to the control module 4 via a connecting line 42. The connecting line 42 can be composed of an input or output connector attached to the elastic element 1 and the connecting line 42. The connecting line 42 can be installed between two test elements 2 and attached to the elastic element 1, or the connecting line 42 can be directly soldered to the elastic element 1. The test element 2 is then connected to the test element 2 using the connecting line 42, and an insulating protective silicone coating is applied when the test element 2 is connected to the connecting line 42.

[0036] like Figure 1-5 As shown, in a preferred embodiment of the present invention, the detection device of the connector 3 further includes a mounting shell 41. The mounting shell 41 is provided with a cavity for installing the control module 4. The control module 4 is connected to the detection component 2 through a connecting line 42. The mounting shell 41 is provided with a positioning groove 411 for positioning the connecting line 42.

[0037] In this embodiment of the invention, preferably, two detection elements 2 can be provided and respectively installed on both sides of the first mounting hole of the elastic element 1. The two detection elements 2 can be located in the same direction as the hole diameter, so that the detection elements 2 can detect the pressure data signal generated by the deformation of the first mounting hole on the elastic element 1 by the connector 3 when tightening or loosening and transmit it to the control module 4. Multiple detection elements can be provided and connected in series with the control module through connecting wires. The shape of the detection elements can be square or circular. In this case, the connecting wires can be directly soldered. Alternatively, when two detection elements are set, the line connecting the positions of the first detection element 2 and the second detection element 2 can coincide with the straight line direction of the diameter of the first mounting hole. This is used to detect the magnitude of the force exerted by the connector 3 on the first mounting hole of the elastic element 1. When the elastic element 1 is subjected to the force caused by the connector 3 tightening or loosening, the deformation of the elastic element 1 will affect the resistance of the internal conductive layer of the patch pressure sensor, thereby changing the direction and magnitude of its current flow, and generating an electrical signal that is transmitted to the control module 4. The control module 4 then outputs whether the connector 3 needs to be reinforced.

[0038] like Figure 2-3 As shown, in another preferred embodiment of the present invention, the detection device of the connector 3 further includes a mounting shell 41. The mounting shell 41 is provided with a cavity for installing the control module 4. The control module is plugged and plugged into the detection component 2 through the connector 43. The mounting shell 4 is provided with a positioning groove 411, which is used to position the connecting line 42 on the connector 43.

[0039] In this embodiment of the present invention, preferably, the control module 4 installed on the mounting shell 41 can be electrically connected to the detection element 2 by plugging and unplugging the connector 43. After the detection element 2 on the elastic member 1 is fully connected in series by the connecting line 42, another connector 43 connected to the control module 4 is provided at the connection point. During use, the connector 43 of the control module 4 installed on the mounting shell 41 can be directly plugged into the other connector 43 on the detection element 2. When it is necessary to disassemble and remove the mounting shell 41, disconnect the connection of the connector 43, and the mounting shell 41 and the control module 4 installed on the mounting shell 41 can be removed as a whole. At this time, the positioning groove 411 is used to position the connecting line 42 connected to the connector 43 so that the control module 4 can be electrically connected to the external device.

[0040] like Figure 2 As shown, in a preferred embodiment of the present invention, the mounting shell 41 is mounted on the elastic member 1 and covers the detection member 2.

[0041] In this embodiment of the utility model, preferably, the mounting shell 41 can be an arc-shaped shell with a cavity. The mounting shell 41 can be provided with a recess for positioning the connector 3 and both sides can completely cover the detection element 2 to protect the detection element 2 and the connecting line 42 connected to the detection element 2. A positioning groove 411 for positioning the connecting line 42 is provided on the wall surface of the mounting shell 41.

[0042] like Figure 6 As shown, in a preferred embodiment of this utility model, the mounting shell 41 is a semi-enclosed shell, and the positioning groove 411 is a square groove on the inner wall surface of the mounting shell 41, with the opening of the positioning groove 411 facing the elastic member 1; in the installed state, a cavity is formed between the inner wall surface of the mounting shell 41 and the surface of the elastic member 1 being tested.

[0043] In this embodiment of the utility model, preferably, the mounting shell 41 is a semi-enclosed shell with a certain height. The arc-shaped structure can be a U-shape or a ring to bypass the first mounting hole. The ring completely covers all the detection pieces attached to the elastic element. The selection can be made according to the number of detection pieces attached to the elastic element. The two ends of the U-shape are of equal height and can completely cover the detection pieces 2 to provide a certain protection for the detection pieces 2. The outer side of the U-shape completely covers the connecting line 42 and a square positioning groove 411 is provided on its outer wall surface so that the connecting line 42 connected to the connector passes through the positioning groove 411.

[0044] like Figure 6 As shown, in a preferred embodiment of this utility model, the detection device for the connector 3 further includes a connection module and a temperature detection module. The connection module is used for external data transmission, and the temperature detection module is used for detecting temperature changes in the elastic member 1.

[0045] In this embodiment of the present invention, preferably, the control module 4 can be a fan-shaped circuit board mounted on the wall of the mounting shell 41. The circuit board can be a module containing ADC (Analog-to-Digital Conversion) signal sampling and pressure signal processing, and a temperature sensor can also be added to detect the temperature change of the connector 3 so that the staff can take the next step according to the change. Corresponding electronic devices and the control module 4 can be set on the circuit board, such as multiple interfaces with the detection component 2 and the connecting line 42, as well as the main control unit, Bluetooth module, Wi-Fi and other wireless communication modules of the same type, so that the control module 4 can transmit the pressure signal and pressure data transmitted by the detection component 2 to the corresponding connected device wirelessly or wiredly so that the staff can check the tightness of the connector 3.

[0046] like Figure 1-6As shown, a connector 3 with a detection device is provided in an embodiment of the present utility model. The connector 3 with the detection device is provided with an elastic member 1, a connector 3 and a detection device for the connector 3.

[0047] The elastic element 1 is provided with a first mounting hole for fitting the connector 3, and the detection element 2 is attached to the elastic element 1 and distributed circumferentially with the first mounting hole as the center.

[0048] In this embodiment of the utility model, preferably, the elastic member 1 can be a plate with a certain thickness, or it can be circular. A first mounting hole with the same outer diameter as the rod of the connector 3 is provided at the center of the elastic member 1 so that the connector 3 can be sleeved on the elastic member 1 and connected to the equipment. Two detection elements 2 can be provided and installed on both sides of the first mounting hole of the elastic element 1 respectively. The two detection elements 2 can be located in the same straight line as the hole diameter, so that the detection elements 2 can detect the pressure data signal generated by the deformation of the first mounting hole on the elastic element 1 when the connector 3 is tightened or loosened and transmit it to the control module 4. The line connecting the positions of the first detection element 2 and the second detection element 2 can coincide with the straight line direction of the first mounting hole diameter, so as to detect the magnitude of the force exerted by the connector 3 on the first mounting hole of the elastic element 1. When the elastic element 1 is subjected to the force brought about by the tightening or loosening of the connector 3, the deformation of the elastic element 1 will affect the resistance of the internal conductive layer of the patch pressure sensor, thereby changing the direction and magnitude of the current flow, and generating an electrical signal that is transmitted to the control module 4. The control module 4 outputs whether the connector 3 needs to be reinforced.

[0049] like Figure 1-6 As shown, in a preferred embodiment of the present invention, the first mounting hole is located at the center of the elastic element 1, the elastic element 1 is a washer or a disc spring, the connecting element 3 is a bolt and nut combination, and the elastic element 1 is connected in series on the bolt.

[0050] In this embodiment of the utility model, preferably, the detection device for the connector 3 mainly consists of an elastic element 1 and a detection element 2. The connector 3 can be a bolt or nut, etc., and the elastic element 1 can be a washer, disc spring, etc., connected to the bolt or threaded sleeve and deforms when the connector 3 is tightened or loosened. The connector 3 is installed on the elastic element 1 through a first mounting hole. The detection element 2 includes a mounting shell 41 and the detection element 2. The mounting shell 41 is used to protect the installation of the detection element 2 and the control module 4 connected to the detection element 2. Using the detection element 2 installed on the elastic element 1, the pressure generated by the elastic element 1 when the connector 3 fitted into the first mounting hole is tightened or loosened is detected, and the detection is recorded. The received signals and pressure change data are transmitted to the control module 4. This allows the detection of the stress value or stress change value generated when the connector 3 is fitted onto the elastic element 1 and squeezes the first mounting hole of the elastic element 1. The generated signals are then transmitted to the control module 4. The detection element 2 detects the deformation of the elastic element 1 when the connector 3 is tightened or loosened, and transmits the generated electrical signals or signal data to the control module 4. This allows for a quick determination of the current tightness of the connector 3. If loosening occurs, it is convenient for staff to repair it. If it is not loose, there is no need for staff to tighten it one by one, saving time and effort and improving efficiency for the staff.

[0051] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model.
