In the figure: 1. a jig base; 2. a water green glass fiber insulation board; 3. gold-plated copper blocks; 4. and (5) a support leg.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1, an embodiment of the present application provides a surface lap impedance testing jig for testing a shielding conductive tape, which includes a jig base 1 and a water green glass fiber insulating plate 2 fixed on the jig base 1. Two caulking grooves are formed in the end face of the top of the water green glass fiber insulation board 2 in parallel, a gold-plated copper block 3 is embedded in each caulking groove, the gold-plated copper block 3 is made of red copper for gold plating, and supporting legs 4 are arranged at four corners of the bottom of the jig base 1.

It should be noted that the water green glass fiber insulation board 2 is also called an epoxy glass fiber insulation board, which generally shows water green, and is called as the water green glass fiber insulation board 2.

When the device works, the two ends of a low-impedance product to be tested are respectively lapped on the two gold-plated copper blocks 3, then certain force is applied to roll the product, so that the product is fully contacted with the gold-plated copper blocks 3, and finally two meter pens of a multimeter or an ohm meter are respectively connected to one sides of the two gold-plated copper blocks 3 for testing and reading numerical values.

In the above way, the water green glass fiber insulation board 2 has the characteristics of insulation, wear resistance, high pressure resistance and corrosion resistance, so that the working surface of the water green glass fiber insulation board can keep high flatness, the contact tightness of the product and the gold-plated copper block 3 is improved, the gold-plated copper block 3 is made of red copper for gold plating, and the red copper has lower internal resistance, so that the resistance of the product obtained by testing is more accurate.

On the basis, the caulking groove is a T-shaped caulking groove which penetrates through one side of the water green glass fiber insulation board 2, the gold-plated copper block 3 is a T-shaped gold-plated copper block matched with the T-shaped caulking groove, one end of the T-shaped gold-plated copper block is embedded in the T-shaped caulking groove, and the other end of the T-shaped gold-plated copper block extends out of the outer side of the water green glass fiber insulation board 2.

Specifically, T type gold-plated copper block is spacing to be inlayed in T type caulking groove for the connection of gold-plated copper block 3 and the fine insulation board 2 of water green glass is more stable convenient.

In the above mode, two the outside that the T type gilding copper billet other end stretches out to the fine insulation board 2 of water green glass is formed with two connection contact, can satisfy the user simultaneously and press from both sides the demand of surveying or the point survey reading data, and preferred adopts the method of pressing from both sides the survey, and the pen-shape metre electrical property centre gripping of universal meter is on connection contact, is difficult to appear the condition of disconnected, and data display is more stable.
