Description

A kind of board-like filtering electrical connector

Technical field

The utility model relates to mechanical field, and a kind of board-like filtering electrical connector is provided especially.

Background technology

Mostly be the tubular type filtering electrical connector on the market now, but the tubular type filtering electrical connector is subjected to the constraint of filtering pipe diameter, its inner space has limitation, can't make the tubular type filtering electrical connector for the connector that high density hole group is arranged.So want to make high density hole group also can make the scheme that the filtering product must have other saving space, the board-like filtering electrical connector of the utility model is born thus.It also can effectively carry out filtering, shielding, stable performance to high-frequency interferencing signal, the product percent of pass height.

The utility model content

The purpose of this utility model is to overcome the deficiencies in the prior art part, and a kind of board-like filtering electrical connector is provided especially

The utility model provides a kind of board-like filtering electrical connector, it is characterized in that: include housing 1, interface sealing body 2, sealing ring 3, the preceding insulator 4 of pin, jump ring 5, grounding reed 6, filter assembly 7, grommet 8; Wherein grounding reed 6 is connected with housing 1, be installed in the groove of housing 1, filter assembly 7 is installed in the housing 1 and tightens with jump ring 5, and insulator 4 is installed in the housing 1 before the pin, with jump ring 5 chuckings, interface sealing body 2, sealing ring 3, grommet 8 are connected with housing 1 respectively.

Described board-like filtering electrical connector, filter assembly 7 include contact pin 9, filter band 10, magnetic tube 11, insulator 12, insulator 13; Wherein contact pin 9 is connected with insulator 12, insulator 13, and filter band 10 is connected with insulator 12, insulator 13, is with the scolding tin circle on the contact pin 9, and magnetic tube 11 is installed on the scolding tin circle, and magnetic tube 11 is connected with filter band 10.

Described board-like filtering electrical connector, contact pin 9 passes interface sealing body 2, and interface sealing body 2 is connected with housing 1.

Because filtering device mostly is a ceramic material, be easy to be mechanically damaged, so the employing of tubular type filtering electrical connector is conductive rubber ground connection.But contain rubber material in the conductive rubber, its conductance is certainly not as metal, and earth resistance directly has influence on the insertion loss objective of filtering electrical connector, so the insertion loss objective of board-like filtering electrical connector is than the height of tubular type.

Filtering device all is relevant with electric capacity, for board-like filtering electrical connector, wants electric capacity to increase, and the thickness of filter band also will increase.So, reduce cost, just can not locate with filter band in order to make product seriation; The location of product inner components is independently, can not be subjected to filter band thickness change and change.The thickness that is to say filter band be can be between a scope random value, can not influence the contact length and the location of contact.

Advantage of the present utility model: adopt π type structure, can effectively carry out filtering, shielding, stable performance, the product percent of pass height to high-frequency interferencing signal; Solved the problem that high density electrical connector can't add filter function, the tubular type filtering electrical connector is owing to be subjected to the constraint of filtering pipe diameter, can't be implemented on the electric connector of high density hole group, the shared cover filter band of all contacts in the board-like filtering electrical connector, and it is insulated from each other, saved the inner space, thereby realized that high density electrical connector can add filter function.
