However, when the stylus or the clip measures the resistance, there is a point contact with the conductive material, which is suitable for the measurement of traditional linear resistors. When used to measure the resistance of planar conductive materials, the error is large and it cannot be used effectively.

[0004] Therefore, there is an urgent need in the market for a device that can accurately measure the resistance of a planar conductive material. Utility Model Content

[0020] Combination Figure 1 to Figure 2 The device for measuring the resistance of planar conductive materials of the utility model is further described.

[0021] A device for measuring the resistance of planar conductive materials is characterized by comprising a measuring frame 1, an end face clamping assembly 3 and a resistor 2.

[0022] The end face clamping assembly 3 has two groups, which are respectively arranged on the left and right sides of the measuring frame 1, and are used to clamp the two end faces of the planar conductive material to be measured placed on the measuring frame 1. Each group of end face clamping assembly 3 includes a conductive layer 31 fixed on the measuring frame 1, a pressing layer 33 that can move toward or away from the conductive layer 31, and a cylinder 34 arranged on the measuring frame 1 and used to fix the pressing layer 33. The conductive layer 31 and the pressing layer 33 are long strip structures extending in the same direction, that is, they both extend along the front and rear direction of the measuring frame 1, and a long strip end face clamping area 32 is formed between the conductive layer 31 and the pressing layer 33 to clamp the end face of the planar conductive material.

[0023] The resistor 2 is connected between the conductive layers 31 of the two groups of end face clamping assemblies 3 through the wire 6 to measure the resistance of the planar conductive material to be measured.

[0024] Specifically, the measuring frame 1 includes a left frame 11 and a right frame 12, and two end face clamping assemblies 3 are respectively arranged on the left side of the left frame 11 and the right side of the right frame 12. The left frame 11 is slidably fitted on the right frame 12 and can move toward or away from the right frame 12. When performing resistance detection on planar conductive materials of different lengths, the left frame 11 is slid relative to the right frame 12, and the distance between the two end face clamping assemblies 3 is adjusted, so that the end faces of the two ends of the planar conductive material on the measuring frame 1 are in a tightened state when being clamped by the end face clamping assemblies 3, so as to ensure the effective measurement of the resistance of planar conductive materials of various sizes.

[0025] A T-shaped slide rail 122 extending leftward and rightward is provided on the left side of the right frame body 12 , and a T-shaped slide groove cooperating with the T-shaped slide rail 122 is provided on the left frame body 11 to achieve sliding cooperation between the two.

[0026] In order to improve the stability of the sliding fit between the left frame 11 and the right frame 12 , a support plate 121 is further provided on the left side of the right frame 12 , and a T-shaped slide rail 122 is arranged on the upper surface of the support plate 121 .

[0027] In order to ensure the flatness of the upper surfaces of the left frame 11 and the right frame 12, the height of the support plate 121 is lower than the height of the right frame 12, and a stepped structure is formed between the support plate 121 and the right frame 12, so that the planar conductive material to be tested can be arranged flatly on the upper surfaces of the left frame 11 and the right frame 12.

[0028] An upper fixing plate 7 is provided on the left side of the left frame 11 and the right side of the right frame 12. The upper fixing plate 7 can be installed on the left frame 11 and the right frame 12 through a column. In this embodiment, the upper fixing plate 7 is formed by bending the left side of the left frame 11 and the right side of the right frame 12 upward and then folding inward. In the same set of end face clamping components 3, the conductive layer 31 is fixed on the lower surface of the upper fixing plate 7, and the pressing layer 33 is located directly below the conductive layer 31. The pressing layer 33 is driven by the cylinder 34 to move up and down, so that the end face of the planar conductive material is clamped up and down.

[0029] A compression layer accommodating groove 13 is provided on the upper surface of the left frame 11 and the right frame 12. When the compression layer 33 is lowered, it can be accommodated in the accommodating groove 13, so that the upper surface of the compression layer 33 is flush with the upper surface of the left frame 11 or the right frame 12, so that when the end face clamping area 32 is in an open state, the end face of the planar conductive material extends into the clamping area 32, which can prevent the end face of the conductive material from extending into the gap between the lower surface of the compression layer 33 and the upper surface of the frame.

[0030] An elastic layer 5 is arranged between the conductive layer 31 and the upper fixing plate 7 , and the elastic layer 5 can play an elastic buffering and protective role during the clamping process of the clamping area 32 .

[0031] The two upper fixing plates 7 are connected with the connecting terminals 4. The lower ends of the connecting terminals 4 pass through the upper fixing plates 7 and are connected to the elastic layer 5 and the conductive layer 31. The upper ends are located above the upper fixing plates 7 for connection with the wires 6 of the resistor 2.

[0032] In this embodiment, the conductive layer 31 is made of single-sided copper foil, the downward side of which is a rough surface, which can improve the stability of clamping the conductive material; the elastic layer 5 is made of sponge; and the compression layer is an insulating plate.

[0033] When in use, the planar conductive material to be measured is laid on the upper surface of the measuring frame 1, i.e., the left frame 11 and the right frame 12, and at the same time, the end faces of the planar conductive material are inserted into the end face clamping area 32 for clamping, so that the end face of the product to be measured is closely attached to the single-fur copper foil. In this state, the resistor 2 can display the resistance value of the planar conductive material. In this process, since the conductive layer 31 is in full contact with the end face of the product to be measured, i.e., completely attached in the front-to-back direction, the resistance value of the planar conductive material can be accurately measured, and the measurement is convenient.
