Abstract

The utility model discloses a static electricity prevention electronic connector, wherein, one end of a metallic shielding body is covered with an insulating tape which is provided with through holes of the corresponding number with that of terminals, the widths of the through holes are smaller than the widths of the terminals so that when the metallic shielding body is arranged on the terminals, owing to the separation of the insulating tape, direct electrical contact can not be generated among the metallic shielding body and the terminals so that static charges accumulated on the terminals can be moved onto the metallic shielding body by the inductive effect to be guided and earthed, and consequently, electrical signals transmitted by the terminals can not be interfered by the static electricity or other external noise to maintain the integrity and the correctness of the transmitted signals.

Description

The antistatic electric power connector

Affiliated technical field

The utility model relates to a kind of electric power connector of eliminating electrostatic interference, is meant especially to eliminate the electrostatic charge that accumulates in around the terminal and the electric power connector of interference phenomenon thereof effectively.

Background technology

Existing electric power connector is generally by insulating body, compositions such as metallic shield body and plurality of terminals, wherein this metallic shield body cover overlays on the insulating body outside, avoid the electromagnetic field of connector outside or electromagnetic noise that the signal of telecommunication that terminal transmitted is produced interference by the metallic shield effect, to guarantee the correctness of transmission signals, as Taiwan patent application No. 89201909 and No. 89218235 respectively at April 11 calendar year 2001 and October 11 calendar year 2001 bulletin, and respectively at the United States Patent (USP) of announcing in July 17 nineteen ninety and on December 1st, 1998 the 4th, 941, No. 849 and the 5th, 842, No. 885 etc., the insulating body outside of the connector that it disclosed all adds the metallic shield body.

But, these metallic shield bodies only can prevent that the electromagnetic field of connector outside or electromagnetic noise from exerting an influence to the signal of telecommunication that terminal transmits, generate an electromagnetic field around the connector inside especially terminal or during build up of electrostatic charge, the mechanism of the electrostatic charge that these metallic shield bodies shortage elimination electromagnetic interference or eliminating are gathered, thus the signal of telecommunication that terminal is transmitted makes a mistake because of being subjected to noise jamming.

The utility model content

Can not eliminate the deficiency of inner electrostatic charge of connector and electromagnetic interference in order to overcome existing electric power connector, the utility model provides a kind of electric power connector, this electric power connector not only can be eliminated effectively and accumulate in bonder terminal electrostatic charge on every side and electromagnetic interference wherein, and unitary construction is firm.

The technical scheme that its technical problem that solves the utility model adopts is: at an end coating insulating tape of its metallic shield body, this insulating tape is provided with and the corresponding through hole of numbers of terminals, these through hole width are less than the terminal width, when making this metallic shield body put on terminal, have the obstruct of insulating tape and can not produce between metallic shield body and terminal and directly electrically contact, but distance only has the thickness of insulating tape between the two, the electrostatic charge of gathering on the terminal can be moved on the metallic shield body by induction effect guide ground connection, and can not disturb the transmission of terminal power on signal.In addition, metallic shield body one end of the present utility model also has elasticity, and when this metallic shield body combined with this connector insulating body, its elastic reaction has certain retain strength can prevent that the metallic shield body from sliding.

The beneficial effects of the utility model are that effectively elimination accumulating in bonder terminal electrostatic charge on every side, prevents electromagnetic interference, guarantee that signal of telecommunication transmission is correct, and the whole fixing of connector is firm.
