Abstract
The utility model discloses a first short -circuit protection mechanism of CPU temperature test, CPU temperature test head pass through an earth connection ground connection, and the earth connection is parallelly connected to have an alarm mechanism, has the fuse in the earth connection. The utility model discloses in the overhead short -circuit protection mechanism that has increased of traditional CPU temperature test, when the heater damage of CPU temperature test head caused the short circuit, the alarm mechanism of short -circuit protection mechanism can play the protection and remind the function, avoids the emergence of conflagration, short -circuit protection mechanism structure is ingenious, low cost, and the protection is reminded in time.
Description
Technical field
This utility model relates to short current protective mechanism, particularly relates to cpu temperature measuring head short current protective mechanism。
Background technology
Cpu temperature test can relate to cylinder and electric heater, cpu temperature measuring head is in the course of action of extruding up and down that cylinder is long-term, electric heater can cause ground short circuit because of aging and stress abrasion, the theoretical value of short circuit current reaches 100A, and earth lead will melt burning when electric current is more than 10A, bigger potential safety hazard can be produced。
Summary of the invention
The purpose of this utility model is to solve the problem that above-mentioned prior art earth lead exists potential safety hazard, it is provided that cpu temperature measuring head short current protective mechanism。
In order to achieve the above object, the technical scheme that this utility model adopts is:
Cpu temperature measuring head short current protective mechanism, described cpu temperature measuring head passes through a ground connection, and described earth lead is parallel with an alarm mechanism, has electric fuse in described earth lead。
Further, described alarm mechanism is LED mechanism。
Further, described earth lead is the spring wire with insulation sleeve。
The beneficial effects of the utility model are mainly reflected in:
(1) adding short current protective mechanism, when the heater breakage of cpu temperature measuring head causes short circuit, the alarm mechanism of short current protective mechanism can play protection prompting function, it is to avoid the generation of fire；
(2) short current protective mechanism structure is ingenious, with low cost, and protection is reminded in time。
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model cpu temperature measuring head short current protective mechanism；
Fig. 2 is the electrical block diagram of this utility model cpu temperature measuring head short current protective mechanism。
Detailed description of the invention
This utility model provides cpu temperature measuring head short current protective mechanism, safe and reliable。Below in conjunction with accompanying drawing, technical solutions of the utility model are described in detail, so that it is more readily understood and grasps。
As it is shown in figure 1, cpu temperature measuring head short current protective mechanism, cpu temperature measuring head passes through earth lead 1 ground connection, and earth lead 1 is parallel with an alarm mechanism 2, has electric fuse 3 in earth lead 1。
Concrete protection process and principle are as follows:
When cpu temperature measuring head is properly functioning, the electric fuse 3 in earth lead 1 is equivalent to a section lead, and resistance is small。The leakage current that normal operation cpu temperature measuring head produces, less than 0.5A, can be directly over earth lead and flow to the earth, and now electric current is without going past alarm mechanism 2。
When cpu temperature measuring head breaks down, for instance during cpu temperature measuring head internal heater short circuit electric leakage, now the electric fuse in earth lead can blow with the increasing of electric current, electric current can pass through alarm mechanism and flow into the earth, and alarm mechanism 2 sends protection warning reminding。
Alarm mechanism 2 in this case carries out refinement describe, alarm mechanism can be sound generating mechanism, LED mechanism etc., when for LED mechanism, as shown in Figure 2, it includes a LED, one end ground connection of LED, the other end is connected with cpu temperature measuring head by the first resistance and is passed through the second resistance eutral grounding, when cpu temperature measuring head is properly functioning, existence due to resistance, electric current can be directly over earth lead and flow to the earth, when the blowout of earth lead, electric current reduces overcurrent through resistance, LED is bright, LED is preferably LED flashing lamp, the warning effect of light flash state is more excellent。
It addition, preferably, earth lead 1 can be the spring wire with insulation sleeve, and spring wire has feature stretchable, bending, stretches and spring wire will not be caused damage, long service life and good looking appearance by bending。
Above the technical solution of the utility model is fully described; it should be noted that; detailed description of the invention of the present utility model is also not limited by the description set out above; those of ordinary skill in the art adopts equivalents or equivalent transformation according to spirit of the present utility model and all technical schemes of being formed in structure, method or function etc., all falls within protection domain of the present utility model。
