Description
Technical field
The present invention relates to consumer electronics field, particularly to a kind of wire protector based on temperature switch applied in electronic digital product data wire terminal.
Background technology
Total it is known that current popularizing due to digital product, battery capacity improves and the increase of charging current.Digital product when charging often security incident take place frequently, wherein considerable part of tracing it to its cause is because the drastically rising of temperature and causes battery explosion even fire to cause person property to be compromised.
Although; for this situation; designers take corresponding safety measure on these digital products such as computer, mobile phone at present; such as add battery charging and discharging protection chip; Thermal Cutoffs etc.; but these means cannot guarantee contingency; practice have shown that substantial portion of potential safety hazard is overheated relevant with charging wire rod; the most in time control the wire rod that charges; making it possible to control the state of digital product charging according to the change of temperature during charging, then avoiding digital product charging temperature too high and security incident occurs is urgent problem instantly.
Summary of the invention
In view of above-mentioned technical problem, the invention provides a kind of wire protector based on temperature switch.This device is by adding in the joint being located at digital product data wire, make it possible to rely on the characteristic of temperature switch the most accurately to measure switch temperature around, when the switch environment temperature being positioned at line joint reaches this critically weighted switched off, switch open circuit, line disconnection stops charging, and when equitemperature declines, switch reverts to Guan Bi automatically, circuit comes back to conducting state, and utilizes temperature control to solve safety problem when charging.
The concrete technical scheme of the present invention is as follows:
Wire protector based on temperature switch; this device includes a shell; it is characterized in that; it is mounted with ceramic PTC in described shell; be mounted with on this ceramic PTC one in upwards arch upward can deformation bimetal leaf, this can deformation bimetal leaf pop-up have one rocking arm connect terminal: described rocking arm connect terminal upper portion be mounted with a spacing cover plate；It is installed on a base plate bottom described ceramic PTC and connects terminal；Described rocking arm connects terminal and is positioned at a contact of housing and is connected terminal at normal temperatures with base plate and contacts and form a conductive path, when any one threshold temperature during the electric current being connected terminal by rocking arm is increased or temperature rises more than 72 to 90 degrees Celsius, lifting then can be inverted play rocking arm by deformation bimetal leaf, make contact portion flick formation disconnecting circuit, now by internal ceramic PTC heating, contact is remained off.
In such scheme, described device is placed in the joint at data wire two ends, and between interface and circuit line, the rocking arm of circuit line input connection device connects terminal, and output termination base plate connects terminal.
In such scheme, described device can be applicable on the data line of current Micro USB interface, Mini USB interface and Type C interface.
In such scheme, described can to take a threshold temperature comprising this number of threshold temperature and positive and negative 5 degrees Celsius when arranging threshold temperature interval.
Protection device based on temperature switch of the present invention monitors temperature about the most in real time by its body, disconnects, when environment temperature reaches the default safe temperature value protection device of temperature switch, blast or the fire generation guaranteeing that environment temperature no longer rises placement initiation immediately；When temperature is less than the recovery temperature value of temperature switch, temperature switch recovers voluntarily to conducting state, make normal circuit operation, thus solve numerous various potential safety hazards brought due to non-original-pack accessory (charger/data wire) improper use: battery explosion, the personal safety as well as the property safety that product burning causes.Additionally this installation cost is low, easily popularizes, applicable large-scale promotion easy to use.

Detailed description of the invention:
For the technological means making the present invention realize, creation characteristic, reach purpose and be easy to understand with effect, below in conjunction with being specifically illustrating, the present invention is expanded on further.
As it is shown in figure 1, wire protector based on temperature switch of the present invention, this device includes a shell 1.Be mounted with ceramic PTC 2 in shell 1, this ceramic PTC 2 is mounted with one in upwards arch upward can deformation bimetal leaf 3, this can deformation bimetal leaf 3 pop-up have one rocking arm connect terminal 4.Rocking arm connects terminal 4 top and is mounted with a spacing cover plate 5.It is installed on a base plate bottom ceramic PTC 2 and connects terminal 6.Rocking arm connects the end of the rocking arm 7 that terminal is positioned at housing and is provided with a contact 8.
As in figure 2 it is shown, under normal circumstances, rocking arm connects terminal and is positioned at the contact of housing and is connected terminal at normal temperatures with base plate and contacts and form a conductive path.
As shown in Figure 3, (a threshold temperature interval comprising this number of threshold temperature and positive and negative 5 degrees Celsius when threshold temperature is set, can be taken) when any one threshold temperature during the electric current being connected terminal by rocking arm is increased or temperature rises more than 72 to 90 degrees Celsius, lifting then can be inverted play rocking arm by deformation bimetal leaf, make contact portion flick formation disconnecting circuit, now by internal ceramic PTC heating, contact is remained off.
As shown in Figure 4, when specifically applying, said wires protection device is serially connected in one end of charging circuit, is commonly positioned at data cable connector portion.Between interface and circuit line, the rocking arm of circuit line input connection device connects terminal, and output termination base plate connects terminal.Equipped with the data wire of this device when product is charged; device monitors the temperature around adapter in real time; when temperature reaches the threshold temperature that device itself is arranged in advance; device can disconnect charging circuit voluntarily and guarantee that environment temperature no longer rises; thus avoid the occurrence of battery explosion, the phenomenon such as product ontology burning thus reach safety protection function, treat that environment temperature declines; device recovers conducting state voluntarily so that can reuse charging.
It is pointed out that this wire protector can be applicable on the data line of current Micro USB interface, Mini USB interface and Type C interface.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; the principle that the present invention is simply described described in above-described embodiment and description; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within scope of the claimed invention.Claimed scope is defined by appending claims and equivalent thereof.
