Abstract
The utility model discloses an electric connector terminal for electrically conductively-butting the chip module and the printed circuit board. The terminal is housed in the terminal hole of the isolation body of the electric connector, comprising a contact part conducively-butted with the tin ball or the conducting strip of the chip module, an end part conductively-butted with the circuit board, and a base connecting the contact part and the end part. The contact part is Y-shaped or divergent, which is convenient for landing the tin ball, and at least part of the contact part is extended out of the terminal hole of the isolation body and elastically contacted with the tin ball of the chip module. The base is offset with a certain angle, thus a space for pressing downward is provided after the contact of the tin ball and the contact part. The contact part is turned to form an angle of 45 degree with the direction in which the terminal hole penetrates the isolation body as the axis, that is, the contact part and the base form an angle of 45 degree. In this way, the contact part of the utility model is positioned along the diagonal direction of the terminal hole of the isolation body of the electric connector, so as to guarantee that the tin ball is provided with bigger downward pressing space and avoid the short circuit which can influence the electrical transmission capability due to the contact of the contact parts of the two adjacent terminals.
Description
[technical field]
The utility model is about a kind of electric connector terminal, especially a kind of electric connector terminal that is electrically conducted chip module and printed circuit board (PCB).
[background technology]

[utility model content]
The utility model provides a kind of electric connector terminal, the tin ball Elastic Contact of this electric connector terminal and chip module, the normotopia degree that can prevent terminal or terminal hole is good and cause terminal collision short circuit, also can guarantee in high density electrical connector, the terminal of Elastic Contact has the bigger space that presses down, and is in contact with one another when avoiding terminals of adjacent to press down and is short-circuited.Electric connector terminal that the utility model provides and tin ball contact site are forked, can increase contact area, reach the excellent electrical property transmission.
Electric connector terminal of the present utility model, be used for being electrically conducted chip module and printed circuit board (PCB), this terminal is contained in the terminal hole of electric connector insulating body, comprise the contact site that tin ball or conducting strip with chip module connect, the end that connects with circuit board and be connected contact site and the base portion of end, contact site becomes Y shape or forked accepting the tin ball substantially, and contact site stretches out insulating body terminal hole and chip module tin ball Elastic Contact; Deviation portion horizontal torsion certain angle, the tin ball has the space of down pushing with after contact site contacts; Contact site is that axis reverses 45 angles with the direction that terminal hole runs through insulating body, make contact site become miter angle with base portion, contact site is along the diagonal of electric connector insulating body terminal hole, can guarantee that the tin ball has the bigger space that presses down, and the contact site of avoiding adjacent both ends is in contact with one another and produces short circuit, influences electric transmission performance.
Compared with prior art, the utlity model has following advantage: the contact site of terminal reverses 45 degree can guarantee that the tin ball has the bigger space that presses down, and avoid the contact site contact of terminals of adjacent and produce short circuit, the short circuit that also can avoid owing to terminal hole or terminal normotopia degree are not good contact site being bumped and cause.The terminal of contact site bifurcated can contact with line or face with the tin ball, increases contact area
