Abstract

The utility model discloses a portable capacitive touch screen testing device, which comprises a box body. A circuit chamber and a battery chamber are arranged in the box body. A dry battery is arranged in the battery chamber. A test circuit is arranged in the circuit chamber. The front surfaces of the circuit chamber and the battery chamber are fixedly provided with a cover plate. The left side of the cover plate is provided with a plurality of LED indicating lamps. The left sidewall of the box body is fixedly provided with a connecting post. The other end of the connecting post is fixedly provided with a mounting plate. The mounting plate is provided with a plurality of small holes, and metal probes are inserted into the small holes. According to the technical scheme of the utility model, the device is light and practical in integral structure, simple in manufacturing process and low in cost. Due to the adoption of the device, the problem in the prior art that a traditional testing device is difficult to carry about and high in cost can be solved. Meanwhile, the device is free from being limited by the field and the power failure and is provided with the probes for realizing the detection. Therefore, the device is quick and convenient to use and high in efficiency.

Description

A kind of portable capacitance touch screen testing device

technical field:

The utility model relates to testing device for touch screens, relates in particular to a kind of portable capacitance touch screen testing device.

background technology:

Along with scientific and technological development, capacitive touch screen is widely used gradually, in the production industry of this electronic product, and test and detection one of the step that is absolutely necessary.Existing capacitive touch screen testing tool is due to the Heavy Weight of self, volume is compared with being not easy to carry greatly, and the most production cost of this tester is high and cause expensive, buy many testers and greatly increased the weight of the cost of investment that enterprise produces, while detecting, need to pass through mains-supplied simultaneously, once have a power failure, just cannot carry out work, affect manufacturing schedule.

utility model content:

The purpose of this utility model is exactly in order to solve existing issue, and provide a kind of portable capacitance touch screen testing device, whole light and handy practical, production process is simple, with low cost, solve traditional test device and carried difficulty and the high problem of price, be not subject to place simultaneously and the restriction that has a power failure, guaranteed manufacturing schedule.

Technology solution of the present utility model is as follows:

A kind of portable capacitance touch screen testing device, include box body, described box body inside is provided with circuit storehouse and battery compartment, is placed with dry cell in battery compartment, and circuit is placed with measurement circuit in cabin, circuit storehouse and battery compartment front are fixed with cover plate, cover plate left side is provided with LED light, and box portion left sidewall is fixed with joint pin, and the joint pin other end is fixed with installing plate, on installing plate, have aperture, in aperture, be inserted with metal probe.

As preferably, described box portion left sidewall has wire hole, and wire hole communicates with circuit storehouse, and wire hole position is corresponding with aperture position on installing plate.

As preferably, described probe right-hand member extends to wire hole and is connected with measurement circuit.

The beneficial effects of the utility model are:

The utility model structural entity is lightly practical, and production process is simple, with low cost, has solved traditional test device and has carried difficulty and the high problem of price, adopt dry cell power supply simultaneously, be not subject to place and the restriction that has a power failure, guarantee manufacturing schedule, probe-type contact detection, efficient and convenient, efficiency is high.

accompanying drawing explanation:

Fig. 1 is the utility model structural representation;

Fig. 2 is the utility model circuit diagram.

In figure: 1, box body; 2, circuit storehouse; 3, battery compartment; 4, dry cell; 5, measurement circuit; 6, cover plate; 7, LED light; 8, joint pin; 9, installing plate; 10, metal probe; 11, wire hole; 91, aperture.

embodiment:

A kind of portable capacitance touch screen testing device, include box body 1, described box body 1 inside is provided with circuit storehouse 2 and battery compartment 3, is placed with dry cell 4 in battery compartment 3, is placed with measurement circuit 5 in circuit storehouse 2, circuit storehouse 2 is fixed with cover plate 6 with battery compartment 3 fronts, cover plate 6 left sides are provided with LED light 7, and box body 1 left side wall is fixed with joint pin 8, and joint pin 8 other ends are fixed with installing plate 9, on installing plate 9, have aperture 91, in aperture 91, be inserted with metal probe 10.

Particularly, described box body 1 left side wall has wire hole 11, and wire hole 11 communicates with circuit storehouse 2, and wire hole 11 positions are corresponding with aperture 91 positions on installing plate 9.
