Description
[technical field]
The utility model relates to a kind of electric connector, relates in particular to a kind of electric connector that is used for flexible printed circuit board is connected to main circuit board.
[background technology]
Be used for flexible printed circuit board is connected to the electric connector of main circuit board, generally comprise versions such as plug type, turnover plate type.Because the utility model mainly is the improvement of being done at the turnover plate type electric connector, so other form electric connectors such as plug type are not given unnecessary details more at this; For the electric connector of turnover plate type, announcing in No. the 6th, 837,740, the United States Patent (USP) on January 4th, 2005 and announcing in the Japanese laid-open patent on February 22nd, 2002 all has announcement No. 3278742.This kind electric connector comprises insulating body, terminal and changes pressing plate.Described insulating body offers the accepting groove with top opening and front openings, described terminal generally comprise be used for the contact arm that electrically connects with flexible printed circuit board and with the pivotal arm of contact arm integrated punching moulding, described commentaries on classics pressing plate is articulated on the insulating body by pivotal arm, and can overturn in opening and closing between the position, when described commentaries on classics pressing plate is positioned at off-position, cover the top opening of accepting groove.The electric connector of said structure form, because pivotal arm and the one-body molded formation terminal of contact arm, need to offer the terminal containing slot of accommodating this terminal with roughly the same being used to of the configuration of this kind terminal on the insulating body, the terminal containing slot of this kind configuration causes a little less than the insulating body relative thin, thereby the structural strength of electric connector weakens greatly.On the other hand, because the contact arm of terminal is for being roughly parallel to the structure that pivotal arm extends again by the downward extension of pivotal arm earlier in the case before above-mentioned, the signal transmission path of terminal is longer, causes the contact impedance of terminal bigger, influences the electrical communications effect of electric connector.
Therefore, necessaryly provide a kind of electric connector that can overcome aforementioned disadvantages.
[utility model content]
The purpose of this utility model is to provide a kind of electric connector that can effectively strengthen the structural strength of its insulating body.
Another purpose of the present utility model is to provide a kind of electric connector that reduces the contact impedance of terminal.
For reaching above-mentioned purpose, the utility model adopts following technical scheme: the utility model electric connector can be connected in flexible printed circuit board on the main circuit board, it comprises: insulating body, its definition has longitudinally, and this insulating body offers the accepting groove with top opening and front openings along longitudinally; Most terminals are in a row to be arranged in the insulating body along longitudinally, and this terminal is provided with the contact site that protrudes into accepting groove; Pivotal arm is to be immobilizated in the insulating body, and described pivotal arm separates setting with terminal; Changeing pressing plate, is to be articulated in rotationally on the insulating body by pivotal arm also can overturn between the opening and closing position, and when described commentaries on classics pressing plate was positioned at off-position, it covered the top opening of accepting groove.
Compared with prior art, the utlity model has following beneficial effect: pivotal arm described in the utility model electric connector separates setting with the terminal that is used for electrically connecting with flexible printed circuit board, be provided with plastics between pivotal arm and the terminal, thereby strengthened the structural strength of insulating body.
Further improvement of the utility model is: described each pivotal arm all be arranged in first row's terminal a certain terminal directly over.Contact arm with respect to terminal in the preceding case is roughly parallel to the structure that pivotal arm extends again by the downward extension of pivotal arm earlier, the contact arm of terminal described in the utility model only has the part that is roughly parallel to the pivotal arm extension, thereby terminal has short signal transmission path, reduce the contact impedance of terminal, improved its electrical communications efficient.
Of the present utility model another is improved to: described pivotal arm is positioned at the top of first row's terminal, and described insulating body definition has longitudinally, and described pivotal arm is being arranged between the two-terminal of terminal first on the longitudinally.The staggered mode of this kind pivotal arm and terminal makes the terminal containing slot of accommodating the conduit of pivotal arm on the insulating body and accommodating terminal misplace on longitudinally and arranges, thereby further strengthened the structural strength of insulating body.
The leading section of the utility model electric connector terminal matches with the block that the position of wall is provided with contiguous insulating body front surface, promptly make the deflection portion of contact site have less angle of inclination, again the docking section of terminal is located, thereby with dock electric connector when butt joint, the docking section of terminal can not collapse under pressure, and can wall is less not to be produced and the loose contact of docking electric connector because of the terminal docking section stretches out.
