[0028] Example 1

[0029] Reference Figure 1-Figure 5 , which is the first embodiment of the present utility model, provides a flicker impedance detection device, which includes a main body component 100, including an impedance probe 101, a connection interface 102 and a wire connector 103. The connection interface 102 is arranged on the impedance probe 101, and the wire connector 103 is sleeved outside the connection interface 102.

[0030] The impedance probe 101 can accurately measure the impedance values ​​of various components in the circuit. An insulating shell is provided on the outside of the impedance probe 101 to isolate the internal conductive part of the impedance probe 101 from the external environment to prevent short circuits and interference. This is a prior art and will not be elaborated in this solution. Those skilled in the art will be able to clearly understand the working principle.

[0031] The connection interface 102 is used to connect the impedance probe 101 to a flicker impedance detection instrument.

[0032] The mounting assembly 200 includes a fixing member 201, which is located on one side of the connection interface 102 and includes a fixing plate 201a, a clamping block 201b, and a first spring 201c. The fixing plate 201a is fixed to the impedance probe 101. The fixing plate 201a defines a first movable groove 201a-1. The clamping block 201b slides in the first movable groove 201a-1. One end of the clamping block 201b is fixed to the first spring 201c, and the other end of the first spring 201c is fixed to the inner wall of the first movable groove 201a-1. The wire connector 103 defines a clamping slot 103-1, and the clamping block 201b can be engaged with the clamping slot 103-1.

[0033] The fixing member 201 is used to fix the wire connector 103 and the connection interface 102, which is convenient for installation. During the detection process, the connection will not become loose due to slight vibration or pulling, thereby ensuring the accuracy and reliability of the detection result.

[0034] The first spring 201c is provided to apply a continuous thrust to the clamping block 201b. When the clamping block 201b is engaged with the clamping slot 103-1, the wire connector 103 and the connection interface 102 are fixed in position, thereby providing a reliable mechanical connection and ensuring a stable connection.

[0035] The mounting assembly 200 also includes a locking member 202, which is arranged on one side of the card block 201b, including a locking block 202a, a connecting plate 202b and a movable plate 202c. A second movable groove 201a-2 is opened in the fixed plate 201a, the locking block 202a slides in the connecting plate 202b, the connecting plate 202b is fixed to one side of the locking block 202a, the fixed plate 201a is opened with a third movable groove 201a-3, the connecting plate 202b slides in the third movable groove 201a-3, the movable plate 202c is fixed on the connecting plate 202b, and a locking groove 201b-1 is opened on the card block 201b, and the locking block 202a can be engaged with the locking groove 201b-1.

[0036] By setting the locking member 202, the position of the clamping block 201b is locked, thereby preventing the wire connector 103 and the connection interface 102 from becoming loose during the detection process, thereby ensuring the reliability of the detection result.

[0037] There are two locking blocks 202a, and the connecting plate 202b connects the two locking blocks 202a, so as to simultaneously unlock the engaged state of the two locking blocks 202a. The movable plate 202c moves along the third movable groove 201a-3 in the direction away from the locking block 201b, driving the connecting plate 202b to move, thereby driving the locking block 202a away from the locking block 201b, separating the locking block 202a from the locking groove 201b-1, thereby unlocking the locking block 201b.

[0038] When the locking block 202a is engaged with the locking slot 201b-1, the position of the locking block 201b will be restricted and cannot move away from the locking slot 103-1, thereby ensuring the stability of the connection between the wire connector 103 and the connection interface 102. When the locking block 202a is separated from the locking slot 201b-1, the movement of the locking block 201b will not be restricted, and the wire connector 103 can be removed and installed.

[0039] Example 2

[0040] Reference Figure 1-Figure 5 , which is the second embodiment of the present utility model, and this embodiment is based on the previous embodiment.

[0041] Specifically, a second spring 202d is fixed to one side of the locking block 202a, and the other end of the second spring 202d is fixed to the inner wall of the second movable groove 201a-2.

[0042] By providing the second spring 202d, a continuous thrust is applied to the locking block 202a, ensuring that the locking block 202a can be engaged with the locking groove 201b-1.

[0043] Specifically, there are two connection interfaces 102 , and the number of the clamping blocks 201 b and the number of the first springs 201 c are corresponding to each other.

[0044] Specifically, a rubber ring 201 d is provided on the outer cover of the connection interface 102 , and one end of the rubber ring 201 d is fixed on the impedance probe 101 .

[0045] The rubber ring 201d is used to cushion the end of the wire connector 103. At the same time, since the rubber ring 201d can be deformed, when the rubber ring 201d is squeezed, the wire connector 103 can be more tightly connected to the connection interface 102.

[0046] Specifically, one end of the clamping block 201b has two inclined surfaces, so that the end surface has a pointed tip, and the end surface of the clamping slot 103-1 has a corresponding pointed tip.

[0047] By setting the end surface as a pointed end, the wire connector 103 can be smoothly removed or installed when the clamping block 201b is not locked.

[0048] Specifically, one end of the locking block 202a is inclined, and the shape of the locking groove 201b-1 corresponds thereto.

[0049] By tilting the setting, when the card block 201b moves in the direction close to the card slot 103-1, the end face of the locking groove 201b-1 will squeeze the inclined surface of the locking block 202a, causing the second spring 202d to be compressed, and the locking block 202a to move away from the locking groove 201b-1. At this time, the locking block 202a will not hinder the movement of the card block 201b. When the card block 201b moves in the direction away from the card slot 103-1, the end face of the locking groove 201b-1 will squeeze the right-angled surface of the locking block 202a. At this time, the locking block 202a will not move away from the locking groove 201b-1, and the card block 201b is restricted and cannot move away from the card slot 103-1.

[0050] Example 3

[0051] Reference Figure 1-Figure 5 , which is the third embodiment of the present utility model, and is based on the first two embodiments.

[0052] Specifically, there are multiple locking grooves 201b-1.

[0053] It is ensured that when the rubber ring 201d is deformed to different degrees, the locking block 202a can be engaged with the locking groove 201b-1, thereby ensuring that the locking block 201b is continuously locked.

[0054] Specifically, a sliding groove 201a-4 is defined in the fixed plate 201a, and the movable plate 202c slides in the sliding groove 201a-4.

[0055] The sliding groove 201a-4 is connected to the third moving groove 201a-3.

[0056] Specifically, a first indicator mark 201 e is fixed to one side of the fixing plate 201 a , and a second indicator mark 201 f is fixed to the connection interface 102 .

[0057] The first indicator mark 201e and the second indicator mark 201f assist in connecting the wire connector 103 to the connection interface 102. When the operator needs to install the wire connector 103, the operator adjusts the wire connector 103 so that the first indicator mark 201e and the second indicator mark 201f are aligned, thereby ensuring that the clamping block 201b and the clamping slot 103-1 are in the same plane, ensuring that after the wire connector 103 is put on the connection interface 102, the clamping block 201b can be clamped with the clamping slot 103-1.

[0058] Specifically, the main assembly 100 further includes a probe tip 104 and a wire 105 . The probe tip 104 is fixed to the impedance probe 101 , and the wire 105 is fixed to the wire connector 103 .

[0059] The probe tip 104 is in direct contact with the object to be measured, and its material is usually selected according to the measurement requirements and the properties of the object to be measured. This is the existing technology and will not be elaborated in this solution. Those skilled in the art can clearly understand the working principle.

[0060] During use, in the initial state, the locking block 202a is engaged with the locking groove 201b-1, and the position of the locking block 201b is locked. The wire connector 103 is brought close to the connection interface 102, and the wire connector 103 is adjusted so that the first indicator 201e is aligned with the second indicator 201f. Then, the wire connector 103 is pushed to the outside of the connection interface 102. When the locking block 201b contacts the wire connector 103, the movable plate 202c is pushed to move along the third movable groove 201a-3 away from the locking block 201b, thereby driving the connection plate 202b to move, thereby driving the locking block 202a away from the locking block 201b. The locking block 202a is separated from the locking groove 201b-1 to unlock the locking block 201b. The wire connector 103 is continuously pushed. The outer surface of the wire connector 103 will press the inclined surface of the locking block 201b, compressing the first spring 201c. At this time, the movable plate 202c is released. When the locking block 201b and the locking groove 103-1 are in a coaxial position, the first spring 201c is restored, and the locking block 201b will be engaged with the locking groove 103-1. At the same time, the locking block 202a and the locking groove 201b-1 are in a coaxial position. The second spring 202d pushes the two to engage. At this time, the wire connector 103 and the connection interface 102 are preliminarily installed.

[0061] The movable plate 202c is pushed again, and the wire connector 103 is pushed. The rubber ring 201d is squeezed, and the wire connector 103 can continue to move a short distance toward the impedance probe 101. At this time, the inclined surface of the locking groove 103-1 will squeeze the inclined surface of the locking block 201b, causing the locking block 201b to move upward a short distance. At this time, the movable plate 202c is released, and the second spring 202d will push the locking block 202a to engage with the locking groove 201b-1 again, limiting the movement of the locking block 201b, thereby improving the tightness of the connection between the wire connector 103 and the connection interface 102.

[0062] When disassembly is required, the movable plate 202 c is pushed to release the locking block 201 b , and then the wire connector 103 is pulled to separate it from the connection interface 102 .

[0063] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, and all of these should be included in the scope of the claims of the present invention.
