Description
Technical field
The present invention relates to a kind of grounding connectors more particularly to a kind of for by the grounding connector of the earthing of casing of UPS.
Background technique
UPS (Uninterruptible Power System, uninterruptible power supply) is a kind of exchange containing energy storage device
Power supply.Mainly continual power supply is provided to load when having a power failure using energy storage devices such as batteries.When alternating current input is normal
When, UPS will be supplied to load to use (utility mode) after alternating current pressure stabilizing, when commercial power interruption (forced outage), UPS is utilized immediately
The electric energy of energy storage device to load continue supply alternating current (battery mode), make load maintain work normally and protect load it is soft,
Hardware is not damaged.
As numerous electric appliances, due to safety concerns, the accidents such as electric shock occur in order to prevent, and the shell of UPS is ground connection.
But before factory, it usually needs carry out Hi-Pot (high pressure) test to UPS, and carry out needing first to disconnect UPS when this test
Shell is electrically connected with the earth.Therefore, it is necessary on the shell of UPS setting can easily connect or disconnect and to be electrically connected with ground wire
The earthing or grounding means connect.Since under normal conditions, UPS is the back side plate earthing by shell, therefore this earthing or grounding means is usual
It is arranged on the backplate of UPS.
Fig. 1 shows a kind of structural schematic diagram of earthing or grounding means in the prior art.Dashed circle part institute as shown in figure 1
Show, which is arranged in the inside of the backplate 1 of UPS, i.e., backplate towards the side inside UPS.The earthing or grounding means
2 screw 22 including PCBA (printed circuit-board assembly) 21 and thereon, wherein the screw 22 is used to be connected to the ground inside UPS
Line (not shown), by the earthing of casing of UPS.The PCBA is arranged to perpendicular to backplate 1, and by L-shaped first jiao
Iron 25 is fixed on backplate 1.Wherein first angle bar 25 is connected to the insulated part of PCBA, not with any line in PCBA
Road connection, and function only as the effect that PCBA is fixed to backplate 1.PCBA is electrically connected with backplate 1 by L-shaped second

It is spaced a distance between end and backplate 1.One screw 26 screws in from the outside to the inside via the through-hole on backplate 1, and
It is connected to the second end of second angle bar 24, to realize being electrically connected for second angle bar 24 and backplate 1, and with this by the back side
Plate 1 pass sequentially through the second angle bar 24, the conducting wire in PCBA, screw 22 and be connected to ground wire, to realize the ground connection of backplate 1.
When needing to carry out Hi-Pot test, screw 26 is screwed out, being electrically connected for backplate 1 and the second angle bar 24 can be disconnected
It connects, to disconnect the connection of backplate 1 Yu ground wire.
The installation process of this earthing or grounding means is complex, and the higher cost of PCBA used in it.In addition, due to L
Second angle bar 24 of shape there are problems that being easily deformed, and after causing screw 26 to screw out, the second angle bar 24 still connects with backplate 1
Touching, so that the connection of backplate and ground wire can not be disconnected.Therefore, this earthing or grounding means reliability in the prior art is poor, holds
Easily lead to the misconnection of backplate and ground wire.
