Description
Technical field
The utility model relates to antistatic technique fields, and in particular to a kind of earthing or grounding means for rotating mechanism.
Background technique
In the electronics industry, the component punch through damage as caused by electrostatic breakdown is in electronics industry, and especially electronics produces
Most universal, most serious harm in product manufacture.Static discharge may cause device hard breakdown or soft breakdown.Hard breakdown is disposable
The eventual failure for causing device, such as the output and input pull-down or short circuit of device.Soft breakdown can then be such that the performance of device deteriorates,
And its index parameter is made to reduce and cause potential faults.(index parameter reduction institute is good or bad since soft breakdown can make circuit
Cause), and be not easy to be found, failure is run and searched to complete machine causes very burden.Equipment still energy band " disease " works when soft breakdown,
Basic change does not occur for performance, it is likely that by exfactory inspection, but may cause fail again at any time.Multiple soft breakdown can make
At hard breakdown, keeps equipment operation abnormal, both caused damages to user, also influence the sale of producer's reputation and product.
Anti-static method more typical at present is that electrostatic protection monitoring system is reliably grounded and utilized to component
System carries out electrostatic monitoring and protection.For general static component, it is easy to electrostatic is exported by conducting wire via grounding body,
But for the component that needs rotate, if the component and grounding body that directly need to rotate using conducting wire connection, can be such that conducting wire twines
Around, knot, influence need rotate component running and the conducting wire service life.

Axis 22, so that the rotary shaft 22 is steadily connect with the stator 112, the stator 112 made can be with the rotary shaft 22
Synchronous rotary.
4, fastening between the rotor 111 and the rotary shaft 22 can be realized by screwing the fixing piece 1112 to connect
It connects, has the advantages that easy to operate.
5, the other end of the rotation stop piece is fixedly connected with the fixed part 21, so that the fixed part 21 and the stator
Both 112 keep opposite static, so that the conducting wire 12 connecting with the stator 112 also would not be with the rotary shaft
22 rotate and the phenomenon that winding, knot occur.
6, the earthing or grounding means not only can quickly guide the quiet of the rotating mechanism carrying by the earthing module 13
Electricity, can be with the electrostatic situation of rotating mechanism described in overall monitor.
The embodiments of the present invention are described above in conjunction with attached drawing, but the utility model is not limited to
The specific embodiment stated, the above mentioned embodiment is only schematical, rather than restrictive, this field it is common
Technical staff is not departing from the utility model aims and scope of the claimed protection situation under the enlightenment of the utility model
Under, many forms can be also made, these are belonged within the protection of the utility model.
