Connectors as an indispensable part of electronic equipment, and M8 quick connect plug are also common parts of our electronic engineering technology, although the field of use between circuits, but the use of M8 quick connect plug is ever-changing. First, talk about the role of the fast connector, the role of the fast connector is very simple: it is to make a link between the blocked or isolated circuits in the circuit, set up a bridge of communication, so that the circuit circulation, so that it takes effect in accordance with the predetermined function.
The structure and form of the M8 quick connect plug is diverse, with the operation of the different, different application objects, equipment frequency and power are not the same to produce various forms of connectors, such as the computer hard disk connector and the car machine tool connected to the machine, and the common TV remote control connector is very different. In many devices, you follow the circuit dredging route observation, you will see more than one connector, so the use of the connector there are many ways, but no matter what type of structure of the connector has a standard role: to ensure the smooth and reliable continuous flow of current.

Torque standard development of M8 quick connect plug.
1. Prepare test equipment: electric screwdriver, torque meter, machine, various specifications of screws.
2. The actual measurement is to lock each specification screw with different torque, and immediately measure the unlocking torque value. The unlocking torque should be 60% or more of the locking torque value.
3. Use the torsion meter to directly measure the value of the destructive torque, which will cause the torque value of the slip tooth, slide wire, screw break or screw head.
4. Find the appropriate torque value, Ex: it is found that the screw failure torque value of the lock PCB board is 16kgf.cm, then the upper limit of the appropriate torque is 16/2=8kgf.cm, so the appropriate torque value is 7±1kgf.cm. Note: According to the characteristics of the screw specifications of our products, the safety factor of the torque value is 2, to avoid the operation due to the lock torque value is too large, resulting in the lock will slip teeth, slip wire, screw head.
5. Verify the reliability of appropriate torque values.
a. Repeat locking and measure the torque value.
b. Take the product locked with the appropriate torque value for vibration test, check whether the screws are loose, and use the torque measurement to measure whether the unlocking torque of each screw is greater than or equal to 60% of the appropriate torque value.
6. Screw torque standard (currently commonly used screw torque standard):

7. Basic principles of locking of M8 quick connect plug:
When screws and nuts are used to lock the locked object and torque is applied, the following forces are mainly generated:
Friction of M8 quick connect plug: occurs between the inner and outer threads themselves and between the nut and the locked object. Tension: The torque will cause the screw to stretch (such as a spring), and when the torque is less than the surrender strength of the screw itself (if the screw deformation can be restored after the withdrawal of the force), the screw's own force will clamp the lock. Therefore, in the process of tightening the nut, the torque must overcome the friction of the screw and the nut itself before the screw and the nut can begin to rotate. When the nut falls along the thread line, the screw will stretch, and when the torque is too large, the screw stretch exceeds its elastic range, it will cause permanent deformation.
8. Analysis of locking factors of M8 quick connect plug:
Friction: Usually most of the torque is used to overcome friction, and only 10-15 of the torque is really converted into the tension inside the screw.
Factors affecting friction:
Lubrication, screw material quality, thread surface smoothness, thread accuracy.
9. Usually uneven force performance of M8 quick connect plug:
The verticality of the bearing face of the nut relative to the axis of the bolt, the thickness deviation of the nut itself, and the tilt of the bolt itself on the locked object.
The surface of the locked object itself has a certain tilt Angle. The wrench applied force correctly during installation.
10. Operation procedures installation method of M8 quick connect plug: should be slow, flat, smooth way to gradually apply the locking screws.
