In RF coaxial connector, jack contact piece structure form is varied, but in some aspects of the requirements are essentially the same, such as: insertion and removal forces, contact resistance and mechanical life in conformity with the relevant standards. Use up or slotted jack contact piece. Series of products, specifications, the use of different conditions, slotted plug hole contact pieces of the structure, specification (inside, outside diameter ), slotted quantity, slot width, slot length is also different. In the structure, the slotted jack contact piece through the form of conical form of compensation, and" brush" form; in the specifications, different series of RF coaxial connector, the plug jack contact member is substantially different in the slotted specifications; quantity, there are 2, 4, 6 slot slot slot slot, 8, and 3 grooves and the the other slot number.

RF coaxial connector for many varieties, appear invalid status also differ in thousands of ways, but from the aspect of reliability to see, a lot of failure mechanism and mode are the same. To accept the connection failure; failure: reflex; electrical contact failure; contamination failure. In RF coaxial connector of the electric contact failure, slotted jack contact piece plays a vital role, especially in the miniature RF coaxial connecting connector, RF coaxial connector electrical contact failure is the most by a slotted plug jack contact member structure, material, technique and improper or is damaged caused by.

In RF coaxial connector, particularly small, compact high performance microwave connector, slotted plug jack contact member status play a decisive role, on the one hand, jack contact piece structure, diameter size and the outer contact member, dielectric matter together, deciding the RF coaxial connector of the range of working frequency, impedance, reflection main electrical performance finger mark; on the other hand, jack contact piece structure, slot number, slot length, which determines the insertion and removal forces, contact resistance, mechanical life properties.
