Signal testing device of capacitive screen

Abstract

The invention relates to a signal testing device, in particular to a signal testing device of a capacitive screen. The technical problem is to provide a signal testing device for a capacitive screen, which can respectively guide testing wires, prevent the testing wires from being knotted and can realize automatic wiping at the same time. According to the technical scheme, the signal testing device of the capacitive screen comprises a signal tester, guide rails, testing lines, first springs and the like, the four guide rails are arranged on the left side of the top of the signal tester, the testing lines are arranged in the guide rails in a sliding mode, and the first springs are arranged between the rear sides of the testing lines and the rear sides of the guide rails. By moving the sliding plate, a test line can be quickly inserted into the docking port, then information testing is performed on the capacitive screen, tested data are transmitted into the display screen, people can conveniently watch the capacitive screen, the sliding plate can be clamped by the clamping block, and the test line is prevented from automatically falling off.

Description

technical field [0001] The invention relates to a signal testing device, in particular to a signal testing device for a capacitive screen. Background technique [0002] With the continuous development of technology, there are more and more capacitive screens. When producing capacitive screens, it is necessary to test the signal of the capacitive screen. Now there are many signal test devices on the market. [0003] The patent application number is CN201920555695.8, a capacitive screen signal test device, including a housing, a display screen, a power switch, a test line, a test pen, an external power cord, a detection circuit, a single-chip microcomputer, a signal converter, a partition, and a storage device and dust-proof device, the rear end of the display screen is bonded horizontally to the upper left side of the front end of the housing, the power switch is set on the lower left side of the front end of the housing, and the rear end of the test line is plugged into the ...

AI Technical Summary

Problems solved by technology

[0004] In the process of testing the capacitive screen, the signal test device of the capacitive screen needs to insert the test pen into the detection position, and then the test line will move accordingly. Since the test lines are scattered, it is easy to have a test error during use. In order to solve the situation of knotted lines, a signal test device for capacitive screens that can be automatically wiped can be developed to guide the test lines separately to avoid knotting of the test lines.
