Abstract
The utility model relates to a power connector comprises a plurality of electrodes, wherein the lengths of earth poles in the electrodes are larger than those of the power supply and other electrodes, so that the electrodes are firstly earthed to avoid the power supply from floating before the power supply is switched on; after the power supply is cut off and then the electrodes are not earthed, so that the power supply interface of a desktop computer is more secure and reliable, and electric signals become more stable, thereby the entire system can be effectively protected.
Description
Technical field
The utility model relates to a kind of power connector, particularly relates to a kind of power connector that is applied to electronic product and equipment.
Background technology
See also shown in Figure 1, existing desktop computer power connector, the earth polar 91 of its all link electrodes and other power supplys are the same long with electrode 92, when system host and AC power supplies (civil power) when being in connection status, if the angle of the power connector of insertion mainboard is bad or shake is arranged, is easy to cause the generation misoperation of the mainboard signal of telecommunication and causes damage.The inventor finds to have following problems in the above-mentioned prior art at least: power line contact earlier causes standby (stand-by) voltage owing to the floating empty acutely shake that produces because ground wire does not contact earlier when socket, connector, and causes the CMOS data to be lost.Such operation and problem be created in factory test comparatively common on the assembly line.
So be necessary to propose a kind of improved power connector, avoid the appearance of the problems referred to above, make it have more practicality.
Summary of the invention
The purpose of this utility model is, overcomes the defective that existing power connector exists, and a kind of new power connector is provided, and technical problem to be solved is to make it before energized, and first ground connection avoids power supply floating empty; After deenergization, make the power interface of desktop computer more safe and reliable thereby disconnect ground connection again, it is more stable that the signal of telecommunication becomes, thereby effectively protected whole system.Make it to be suitable for more practicality, and have the value on the industry.
The purpose of this utility model and to solve its technical problem be to adopt following technical scheme to realize.A kind of power connector according to the utility model proposes comprises a base and a plurality of base top electrode that is arranged at, and it is the earth polar of ground connection that one or more electrodes are arranged in the wherein said electrode, and the length in this earth polar is greater than the length of power supply and other electrodes.
The purpose of this utility model and solve its technical problem and can also be further achieved by the following technical measures.
Aforesaid power connector, wherein said base is provided with containment vessel, and described electrode is arranged in the containment vessel.
Aforesaid power connector, wherein said electrode are needle electrode.
Via as can be known above-mentioned, the utility model changes existing design, and ground wire (pin) lengthening with the male connector makes the power interface of electronic product and electronic equipment more safe and reliable, and it is more stable that the signal of telecommunication becomes, thereby effectively protected whole system.
By technique scheme, the utility model has the following advantages at least:
Power connector of the present utility model, made before energized that first ground connection avoids power supply floating empty owing to adopt the length of the length in earth polar greater than power supply and other electrodes; After deenergization, disconnect ground connection again, make the power interface of electronic product and electronic equipment more safe and reliable, it is more stable that the signal of telecommunication becomes, thereby effectively protected whole system.
In sum, the power connector of the utility model special construction, it has above-mentioned many advantages and practical value, and in like product, do not see have similar structural design to publish or use and really genus innovation, no matter it structurally or bigger improvement all arranged on the function, have large improvement technically, and produced handy and practical effect, and more existing power connector has the multinomial effect of enhancement, thereby be suitable for practicality more, and have the extensive value of industry, really be a new and innovative, progressive, practical new design.
Above-mentioned explanation only is the general introduction of technical solutions of the utility model, for can clearer understanding technological means of the present utility model, and can be implemented according to the content of specification, below with preferred embodiment of the present utility model and conjunction with figs. describe in detail as after.
Embodiment of the present utility model is provided in detail by following examples and accompanying drawing thereof.

Embodiment
Below in conjunction with accompanying drawing and preferred embodiment, to according to its embodiment of power connector, structure, feature and the effect thereof that the utility model proposes, describe in detail as after.
First embodiment
See also shown in Figure 2ly, a kind of power connector that preferable first embodiment of the utility model proposes comprises a base 10 and 3 electrodes, and 3 electrodes all are arranged on the described base 10.The earth polar 21 that to have only an electrode in the electrode be ground connection, the length in this earth polar 21 is greater than the length of power supply and other electrodes 22.The lead that extends from base 10 is an extended line 30.Because the length in earth polar 21 is greater than the length of power supply and other electrodes 22, therefore, before energized, earth polar 21 first ground connection avoid power supply floating empty; After deenergization, disconnect ground connection again, make the power interface of desktop computer more safe and reliable, it is more stable that the signal of telecommunication becomes, thereby effectively protected whole system
Second embodiment
See also shown in Figure 3ly, a kind of power connector that preferable second embodiment of the utility model proposes has 7 electrodes, has only one to be earth polar 21 in 7 electrodes, and the length in this earth polar 21 is greater than the length of power supply and other electrodes 22.Described electrode is a needle electrode.Other structures and operation principle are with first embodiment.
