The height of the contact element 30 i.e. cylinder height is h, and copper alloy filament length degree required for wrapping contact 30 is L, then:
The volume that 33 envelope of outer surface forms space is V1, then,
Similarly, it is assumed that the volume V in 34 envelope of inner surface formation space2, then,
The spatial volume V that copper alloy silk can fill3=V1-V2, it may be assumed that
So copper alloy silk filling rate θ should are as follows:
The specific filling rate θ of wrapping contact 30 of the present invention is according to practical string diameter size, application field and use
It is required that etc. because usually determining, generally 15%~95%.
Assuming that the cross-sectional area that 33 envelope of outer surface forms space is S1,34 envelope of inner surface forms the cross-sectional area in space
For S2, the number of share of stock of copper alloy silk required for wrapping contact 30 is n, then any one 30 cross section of wrapping contact is by copper alloy
The accounting rate ρ that silk cross section occupies should are as follows:
The specific accounting rate ρ of wrapping contact 30 of the present invention is according to practical string diameter size, application field and use
It is required that etc. because usually determining, generally 5%~98%.
In conclusion the filling rate θ of wrapping contact 30 of the present invention and accounting rate ρ value model in actual use
It encloses larger, has a great impact to current-carrying capacity, the transmission characteristic of signal etc. of contact.Copper alloy silk filling rate θ be from
Volume angle is set out, and the ratio that copper alloy silk is filled in unit of measurement space, filling rate θ is smaller, and current-carrying capacity is smaller, transmission letter
Number frequency be relatively low；Filling rate θ is bigger, and current-carrying capacity is bigger, and the frequency for transmitting signal is also relatively high；Copper alloy silk
Accounting rate ρ is the ratio that copper alloy silk is filled out of area angle, unit of measurement area, and filling rate ρ is smaller, current-carrying capacity
Smaller, filling rate ρ is bigger, and current-carrying capacity is bigger.
