[0003] Currently, during the process of line checking, a multimeter is needed to measure the continuity of the cable. Under normal circumstances, one hand holds one test probe to detect, but due to the noise on site, the buzzer sound of the multimeter cannot be heard, so one hand needs to hold the multimeter close to the ear to hear.

[0004] However, since the continuity needs to be measured, one probe needs to be grounded, and the other probe needs to be placed on the terminal to be tested. In the above case, this will cause the tester to be unable to hold the probe grounded by hand. If the probe is directly inserted into the grounding terminal of the automatic control cabinet, it will be unstable, which will seriously affect the debugging progress and also reduce the accuracy of line checking, causing safety accidents.

[0044] In order to better understand the above technical scheme, the above technical scheme will be described in detail below with reference to the drawings and specific embodiments.

[0045] Embodiment:

[0046] As shown in Figure 1 The utility model embodiment discloses a wiring assisting device for assisting the ground end of the multimeter pen measuring equipment, and the structure comprises: a conductive box 1 and a plurality of pressing pieces 2.

[0047] The conductive box 1 is made of conductive metal, such as copper, aluminum, silver, etc., and is preferably copper.

[0048] Both side end surfaces of the conductive box 1 have an inlet 1a, which is Figure 3As shown, one inlet 1a is used for inserting the multimeter pen, and the other inlet 1a is used for inserting the pressure pin type terminal on the external wire; and the top surface of the conductive box 1 is provided with threaded holes 1b on both sides.

[0049] A plurality of pressing members 2 correspond to the threaded holes 1b, which are used to press the multimeter pen or the terminal to be measured, thereby ensuring stable connection.

[0050] Specifically, the pressing member 2 includes a driving end 21 and a threaded rod 22.

[0051] The driving end 21 facilitates the operator to drive the threaded rod 22 to rotate, which can be a bolt head, a knob, a rotating wheel, etc., without specific limitation. The top of the threaded rod 22 is connected with the driving end 21, and the rod body is screw-connected in the threaded hole 1b.

[0052] It should be noted that the external wire needs to be made by oneself, and the A end is a pressure pin type terminal, and the B end can be flexibly changed according to the actual situation on site; if there is a grounding terminal row of the electrical cabinet on site, the B end can be a pressure pin type terminal, so as to be directly inserted in the terminal row; if there is no grounding terminal row on site, only a grounding copper row, the B end can be a pressure O type terminal, so as to be fixed by means of a screw.

[0053] When calibrating the line, one end of the external wire is connected to the grounding terminal row, and the pressure pin type terminal at the other end is inserted into one inlet 1a, and then the driving end 21 of the pressing member 2 on that side is rotated, so that the threaded rod 22 gradually rotates into the threaded hole 1b until the pressure pin type terminal is pressed; then the multimeter pen is inserted into the other inlet 1a, and then the driving end 21 of the pressing member 2 on that side is rotated, so that the threaded rod 22 gradually rotates into the threaded hole 1b until the multimeter pen is pressed. At this time, the multimeter pen and the pressure pin type terminal are firmly connected with the conductive box 1, and the electrical connection is completed by means of it.

[0054] Through the above structural design, the electrical connection of the multimeter pen and the pressure pin type terminal can be conveniently and quickly completed, so that one hand can be freed to complete other detection matters, which improves the debugging efficiency, and is suitable for different specifications of cables and multimeter pens, has the advantages of high universality, and is firmly connected and will not fall off due to external slight tension.

[0055] In some embodiments, as Figure 2 shown, one side of the top surface of the conductive box 1 has a plurality of threaded holes 1b arranged along the axis, and the other side of the top surface has one threaded hole 1b.

[0056] Specifically, one side of the conductive box 1 having a plurality of threaded holes 1b is used for inserting the multimeter pen; and the other side having one threaded hole 1b is used for inserting the pressure pin type terminal.

[0057] It should be noted that, since the multimeter pen is relatively long, only one pressing piece 2 may be at risk of falling off, so multiple pressing pieces 2 are provided correspondingly; in this embodiment, two are provided, but three or more can also be provided, without specific limitation.

[0058] Through the above design, the stability of the connection between the multimeter pen and the conductive box 1 is ensured, the accidental falling off is avoided, and the actual use effect is improved.

[0059] In some embodiments, as shown in Figures 1 to 5 In order to facilitate the operation of the detection personnel, the driving end 21 is in a cylindrical structure, and the height is preferably 8 mm, which facilitates simple tightening with fingers without a screwdriver.

[0060] Specifically, the outer periphery of the driving end 21 is provided with a plurality of vertical threads 211 for improving the friction with the fingers and preventing slipping during tightening; the top surface of the driving end 21 is provided with a cross groove 212 for facilitating tightening with a screwdriver.

[0061] In some embodiments, as shown in Figure 2 Further comprising: a protective layer 3 wrapped around the outer periphery of the conductive box 1, and a plurality of through holes 31 are formed on the surface, one-to-one corresponding to the threaded holes 1b, for the threaded rod 22 to pass through.

[0062] Exemplarily, the protective layer 3 can be made of insulating materials such as polyvinyl chloride (PVC), cross-linked polyethylene (XLPE), polypropylene (PP), and rubber, without specific limitation.

[0063] By designing the protective layer 3, protection and insulation are provided to prevent the conductive box 1 from being damaged or disturbed by the external environment.

[0064] In some embodiments, as shown in Figure 2 The conductive box 1 is formed by the top plate 11, two side plates 12, and the bottom plate 13.

[0065] Exemplarily, the length of the conductive box 1 is set to 40 mm, which satisfies the total length of most multimeter metal pen tips and lead terminals on the market; the outer width of the conductive box 1 is set to 7 mm, the inner width is set to 5 mm, the outer height is set to 10 mm, and the inner height is set to 6.5 mm, so as to have enough space to accommodate external wires and multimeter pens.

[0066] Exemplarily, the thickness of the top plate 11 is set to 2.5 mm, which is sufficient to firmly fix the internal wires and multimeter pens, avoiding the risk of wire slipping.

[0067] Specifically, as shown in Figure 4As shown, the bottom plate 13 is a bent plate, and the top has a bent groove 1c with a cross-sectional shape of an isosceles trapezoid; the bent groove 1c has a horizontal surface 1c1 and two inclined surfaces 1c2, and the width of the horizontal surface 1c1 is equal to the diameter of the bottom surface of the threaded rod 22.

[0068] Through the above design, the limiting and guiding effects are achieved, and it is ensured that the threaded rod 22 can always press the wires and the multimeter pen, and the connection firmness is improved.

[0069] On the basis of the above embodiment, as shown in Figure 2 and Figure 4 the bottom of the threaded rod 22 is provided with an annular taper surface 221, which can be attached to the two inclined surfaces 1c2, which improves the pressing and locking effect and improves the connection firmness.

[0070] In some embodiments, as shown in Figures 1 to 3 a limiting baffle 4 is further arranged on the inner side of the conductive box 1.

[0071] Specifically, the limiting baffle 4 is used to limit the insertion depth of the pressure pin type terminal, so that it is in a suitable position, thereby ensuring that the pressing member 2 can fully press the pressure pin type terminal, and the connection firmness is improved.

[0072] In some embodiments, as shown in Figures 1 to 3 and Figure 5 a conductive pad 5 is further arranged on the inner bottom side of the conductive box 1 and below the pressing member 2.

[0073] Specifically, the conductive pad 5 is made of conductive material and is used to support the pressure pin type terminal, so as to avoid the pressure pin type terminal from being turned forward after being pressed by the threaded rod 22, thereby ensuring that the pressing member 2 can fully press the pressure pin type terminal, and the connection firmness is improved.
