Proper use of power connector

2018-08-22 10:48:13 Browse:
The rise of smart wear,mobile phones become thinner and lighter,fast charging leads to the increasing demand for high current connectors,making the application of spring POGO PIN probe connectors more frequent,now the market of smart digital products are basically used to spring POGO PIN thimble connectors,only some low-end products may still use elastic discs.Connector.
Today Yongtan electronic braid with you to explore the following:spring POGO PIN top probe connector in the selection and application of products should pay attention to matters.
Selection of working stroke of spring POGO PIN probe connector
The choice of the spring POGO PIN probe connector must be based on the space of the product used,the choice of power connector is generally composed of plugs and sockets,plugs also known as free end connectors,sockets also known as fixed connectors.Connection and disconnection of the circuit are realized by plugs,sockets,and insertion and separation,so various connection modes of plugs and sockets are produced.This is what many operators know,and the following are mainly for the attention in use:
1,end connection
1)When the power connector is terminated,it should be terminated and checked strictly according to the corresponding termination specifications or requirements,and terminated according to the corresponding contact number.The maximum thickness of insulating layer between cables and conductors should be matched with the distance between contacts,and the connection ends of cable core and contacts should be matched.
2)When welding,the corresponding power should be selected according to the diameter of bare wire.The welding time of each contact should not exceed 5 seconds.It should be noted that the flux should not be allowed to penetrate the insulator so as to avoid the decrease of insulation resistance of the product.
3)When cleaning the power connector(including the cleaning of contact parts),it can be done with silk cloth dipped in absolute ethanol,and used after drying.Acetone and other chemical solvents are not allowed to have harmful effects on the power connector.
4)When the power connector is in the non-plugging state,it must cover the matching protective cover separately or take other dust-proof measures.
2.Pre insert inspection
1)The type,code,number,insertion position and direction of power connector should meet the requirements of design and process documents.
2)the tail cover has no loosening and no closure.
3)the cable bundle or traverse of the tail cover has no bending bending and no damage to the outer skin.
4)the shielded ground wire is not broken,and the welds of the housing are not loose.
5)The shell and interface of the power connector shall be free of deformation,cracks,thread wear,fasteners without loosening or defect,and plating without falling off.
6)the locking device should be intact.
7)the power connector with sealing ring should be intact.
8)no excess is allowed in the interface(insulator surface and socket).
9)pins and sockets should not be skewed or deformed.
10)the surface of the insulator at the root of the needle should not be broken or raised or shedding.
11)Needles and jacks should not be retracted or protruded obviously.Compared with normal pins and jacks on the same plane,the distance of withdrawal or protrusion should not be more than 0.5mm.Otherwise,it should be checked whether the pins or jacks are assembled in place or retracted.
3.Insert operation
1)Before inserting,it is necessary to confirm whether the plug to be inserted corresponds to the socket code,the"shape"of the interface,the"positioning key and slot","positioning color mark","locking screw and slot","positioning screw and screw hole"at the interface,and to locate accurately.
2)When the power connector is pushed in or screwed in,the plug should be aligned parallel to the butt face of the socket and the cable or wire should be centered,then the lock sleeve should be pushed into place gently or slowly along the axis direction and locked.If it is found that the two docking surfaces are skewed,inaccurate positioning,feel tightly beyond the normal force or obstruction and other abnormal feelings,it should stop operation,pull out along the axis direction and carry out state inspection,after troubleshooting,and then re-insert.The use of special auxiliary tools is allowed.
3)when tightening the tail cover of the plug or socket,the outlet cable or conductor of the tail cover can not be turned.
4)When inserting blindly,it is recommended to use illumination and visual functional equipment(such as micro-camera or endoscope and monitor)to monitor the process of inserting blindly.Under the condition of no illumination and monitoring equipment,the blind insertion operation is carried out.The corresponding characteristics of the interface to be plugged in are clearly felt by the fingers,and then the insertion position is inserted and locked.
5)In the locking operation,if it occurs or is found that the normal locking can not occur,it should be promptly pulled out and checked.After checking correctly,it should be inserted and locked according to the regulations.
6)For the power connector of the thick and hard cable,the cable should be fixed to prevent the power connector from being pulled out and damaged due to cable sagging;
7)After the power connector is plugged in and locked,the cable at the outlet of the tail shield should be maintained in a natural stretching state,and the bending starting part of the cable should generally be more than 30 mm away from the tail shield outlet.Unless otherwise specified,the bending radius of the cable should not be less than 4 times of the outer diameter of the cable.
8)When the power connector is plugged and unplugged,the main body of the power connector should be grasped for inserting and unplugging,and the cable or wire outside the tail cover should not be grasped for operation.
4.Test
1)When testing the cable or electronic equipment,the probe should meet the requirements.It is forbidden to use a pen or copper wire for direct testing,so as to prevent the jack of the power connector from poking or damaging the inner wall or touching the pin askew.
2)Before testing the connection of power connectors on test cables and electronic equipment,check the power connectors(plugs and sockets)on test cables,which can not be plugged in if there is any external damage,pin(hole)corrosion,pin distortion,pin deformation,dust pollution,wire breakage,shielding skin broken wire.
3)electricity during testing
