Description

Module connector

[technical field]

The present invention is relevant a kind of module connector with internal circuit board, and what relate in particular to its internal circuit board scurries the conducting wire structure that sound is interfered in order to reduction.

[background technology]

Lifting along with the communication signal transmission speed, requirements such as electric property to the networking interface are also more and more higher, therefore, communication industry association (Communication Industry Association) unites the interfacing standard C at.5 that has released requirements at the higher level with electronic industry association (Electronic Industry Association).This kind interface near-end interfere to require to interfere loss (Near-End Cross-Talk Less) to be no more than-40DB at each near-end that produces between to signal under 100 hertz the signal input condition.

Open the 5th, 186, No. 647 patents of the U.S. promptly disclosed a kind of terminal that utilizes and intersected the method for interfering with the compensation near-end in February, 1993, and with the crossover location of the insulator fixed terminal that is provided with groove mechanism.Interfere and to require standard but this kind interleaved mode can't reach the Cat.5 near-end, and this kind terminal fixed form instability, the terminal crossover location might be changed and influence the effect that anti-near-end is interfered.

In November, 1994 is the U.S. the 5th of White's lattice (Whitaker) company openly, 362, No. 257 patents, this patent disclosure the another kind of anti-near-end intersection terminal structure of interfering, and claim its prevent near-end interfere effect of loss can reach-more than the 40DB, its terminal is to embed integrated injection molding behind the die cavity.But this kind terminal fixing means easily causes the distance between the terminal to be out of shape because of the pressure of the plastic cement that injects fusion, causes the near-end of its each conducting wire to interfere compensation unstable, thereby easily produces defective products.

The 5th, 547, No. 405 patent disclosures of the U.S. that in August, 1996 is open conducting terminal be provided with to intercouple and form the part of electric capacity, interfere to reduce scurrying sound, the sound of scurrying of this kind design interferes the near-end that also can not satisfy the Cat.5 standard to interfere requirement.

The 6th, 447, No. 341 patent disclosures of the U.S. that in September, 2002 is open a kind of conducting wire coupling with circuit board eliminate and scurry sound and interfere to form electric capacity, but its conducting wire shaped design and imperfection, the near-end interference requirement that does not still reach the Cat.5 standard.

Therefore, industry presses for and a kind ofly can satisfy Cat.5 standard near-end and interfere the requirement and the communication module group connector of stable performance.
