Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of grounding impedance, and in particular to a connecting mechanism. Background Art
[0002] An impedance meter, or more generally, an impedance tester, is a precision electronic instrument used to measure the impedance of a circuit or component. Impedance is the overall resistance a circuit presents to an AC signal. It includes not only resistance but also the effects of inductance and capacitance on the AC circuit. The inductive reactance and capacitive reactance of inductors and capacitors, respectively, vary with signal frequency, making impedance a frequency-dependent quantity.
[0003] When an impedance tester is used to detect whether an electrical appliance is leaking electricity, the test lines must first be connected one by one in a manner that matches the tester's port identification, and then the test clip at the other end of the test line must be connected to the electrical appliance. Since the connection end of the test line is inserted into the ground port of the tester, frequent use of the tester for testing will increase the number of plugging and unplugging of the test line, which will increase the wear between the plug and the socket and cause it to become loose. The loose connection may cause unstable or interrupted signal transmission, making it impossible for the tester to accurately read or completely unable to read the data transmitted by the test line, thereby affecting the accuracy of the test results.

[0034] Example 1
[0035] Reference Figures 1 to 6 As shown, the first embodiment of the present invention provides a connection mechanism, which includes a connection element 100, a fixed plate 101, and a rotating component 102 arranged on the fixed plate 101; the detection line and the ground port are effectively aligned.
[0036] The reinforcing element 200 includes slide bars 201 arranged in a circular array on the fixing plate 101 and a clamping assembly 202 provided on the slide bars 201, thereby preventing friction between the detection line and the grounding port.
[0037] During use, the personnel first installs the connecting element 100 on the side of the grounding port 303 on the detector housing 301, and then aligns the detection line and the grounding port through the connecting element 100 to avoid conflict when the detection line and the grounding port are connected, and also avoids friction between the detection line and the grounding port. Then, the personnel clamps and fixes the connection end of the detection line through the reinforcement element 200 to avoid looseness between the detection line and the grounding port due to external force, thereby improving the accuracy of the detection results.
[0038] Example 2
[0039] Reference Figures 1 to 6 As shown, this is the second embodiment of the present invention, which is different from the first embodiment in that: the rotating component 102 includes a card slot 102a arranged in a ring array and opened on the fixed plate 101, a baffle 102b arranged in a ring array and connected to the fixed plate 101, a telescopic rod 102c rotatably connected to the fixed plate 101, and a spring 102d sleeved on the telescopic rod 102c, the two ends of the spring 102d are fixedly connected to the fixed plate 101 and the telescopic rod 102c respectively, the size of the sliding rod 201 is adapted to the size of the card slot 102a, and the position of the connection end of the detection line is adjusted by the rotating component 102, so that the connection end of the detection line can be effectively aligned with the grounding port 303.
[0040] Compared with Example 1, further, the clamping assembly 202 includes a groove plate 202a connected to the sliding rod 201, an arc-shaped rubber plate 202b symmetrically slidingly connected to the groove plate 202a, a fixed plate 202c connected to the arc-shaped rubber plate 202b, a spring 202d symmetrically connected to the fixed plate 202c, and a fixed block 202e connected to the spring 202d. The size of the groove plate 202a is adapted to the size of the detection line connector, the size between the two arc-shaped rubber plates 202b is adapted to the size of the detection line connector, the fixed block 202e is fixedly connected to the groove plate 202a, the inner side of the arc-shaped rubber plate 202b is set as a slope, and the groove plate 202a is fixedly connected to the telescopic rod 102c, thereby avoiding looseness between the connection end of the detection line and the grounding port 303.
[0041] During use, a person inserts the connecting end of the detection line into the inside of the groove plate 202a, so that the connecting end of the detection line contacts the inclined surface provided on the arc-shaped rubber plate 202b. When the connecting end of the detection line moves toward the inside of the groove plate 202a, the groove plate 202a contacts the inclined surface provided on the arc-shaped rubber plate 202b, so that the arc-shaped rubber plate 202b moves toward the outside of the groove plate 202a, so that the arc-shaped rubber plate 202b drives the second fixing plate 202c to move toward the outside of the groove plate 202a synchronously, and the second fixing plate 202c pulls the second spring 202d to extend toward the side away from the groove plate 202a, and the arc-shaped rubber plate 202b contacts the connecting end of the detection line under the elastic action of the second spring 202d, and the connecting end of the detection line is fixed under the clamping action of the arc-shaped rubber plate 202b;
[0042] When the connecting end of the detection line is fixed to the groove plate 202a, the personnel rotates the telescopic rod 102c, causing the telescopic rod 102c to rotate on the fixed plate 101 while driving the spring 102d to rotate. At the same time, the telescopic rod 102c drives the groove plate 202a to rotate synchronously, so that the groove plate 202a drives the sliding rod 201 and the connecting end of the detection line clamped inside the curved rubber plate 202b to rotate synchronously. When the sliding rod 201 is not engaged with the slot 102a and the sliding rod 201 conflicts with the fixed plate 101, the spring 102d is in a stretched state, so that the sliding rod 201 conflicts with the fixed plate 101 under the stretching action of the spring 102d, thereby causing the sliding rod 201 to conflict with the fixed plate 101 while rotating toward the side close to the slot 102a until the sliding rod 201 moves to the position of the slot 102a and the sliding rod 201 is Under the action of spring 102d, it moves toward the inside of the slot 102a, and the sliding rod 201 is engaged with the slot 102a. When the sliding rod 201 is inserted into the slot 102a, the spring 102d drives the telescopic rod 102c to retract toward the side close to the fixed plate 101, and the telescopic rod 102c moves toward the side close to the fixed plate 101 through the groove plate 202a, and the arc rubber plate 202b clamps the connection end of the detection line and connects it with the grounding port. The connection end of the detection line and the grounding port are effectively aligned through the connecting element 100, avoiding wear of the connection end of the detection line and the grounding port 303 after frequent connection. The connection end of the detection line is effectively fixed by the reinforcing element 200, avoiding loosening of the connection end of the detection line and the grounding port 303 due to wear, thereby improving the accuracy of the detector when detecting through the detection line.
[0043] The remaining structures are the same as those of Example 1.
[0044] Example 3
[0045] Reference Figures 5 to 8 As shown, it is the third embodiment of the present utility model. This embodiment is different from the second embodiment in that: the detection element 300 includes a detector housing 301, a bracket plate 302 symmetrically connected to the detector housing 301, and a grounding port 303 symmetrically connected to the detector housing 301. The detector housing 301 is fixedly connected to the fixing plate 101, and the groove plate 202a and the grounding port 303 are on the same horizontal plane, avoiding interference between the detection line and the grounding port when connected.
[0046] During use, multiple groups of detection lines are synchronously connected to the corresponding grounding ports 303 through the groove plate 202a, avoiding the need for personnel to insert the detection lines into the grounding ports 303 one by one, thereby improving the connection efficiency of the detection lines and also improving the working efficiency of the detector.
[0047] The remaining structures are the same as those of Example 2.
[0048] Example 4, as Figures 1 to 8 FIG. 3 is a third embodiment of the present invention. This embodiment provides a method for using a ground impedance detector, comprising the following steps:
[0049] Step 1: Check whether the tester is intact, including whether the test line is in good contact, whether the display is normal, and whether the battery is fully charged.
[0050] Step 2: First, connect the detection line connection end to the ground port 303.
[0051] Step 3: Clean the dirt and rust stains on the surface of the test clip of the test line that affect the conductivity.
[0052] Step 4: Then clamp the two connection end detection clamps at two different positions of the grounding conductor respectively, and the distance between the two clamps should be greater than 0.25 meters.
[0053] 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.
