Description

Electric connector

Technical field

The utility model is meant especially that relevant for a kind of electric connector a kind of terminal is for contacting the electric connector of springing up and down.

Background technology

The bottom surface of chip (as CPU) is formed with a plurality of spaced contacts, and the electric connector that connects this pattern chip utilizes downforce that chip is fixed on the pedestal, uses the terminal Elastic Contact in contact that makes chip and the terminal groove that is arranged in pedestal and guarantees to be electrically connected.

See also Fig. 1 and Fig. 2, be a kind of electric connector that connects chip, it is provided with: pedestal 10, and arrange on it and be provided with a plurality of terminal grooves 11; And a plurality of terminals 14, it is arranged at the terminal groove 11 of this pedestal, and it is provided with the elastic arm 15 and the fixed part 16 of springing up and down, and this fixed part 16 is fixed with terminal groove 11 packings, and this elastic arm 15 is connected in fixed part 16 upper ends, and its proximal end is provided with the contact 17 of protrusion.

See also Fig. 2, when chip 90 places on the pedestal 10, the contact 17 of each contact 91 these each terminal 14 of contact of chip 90; See also Fig. 3, when chip 90 stressed pressing down, each terminal 12 is the receipts that contract by the elasticity of elastic arm 15, and this moment, contact 17 was that elasticity pushes against this contact 91 and reaches the electrical connection effect.

Conventional construction has following shortcoming: promptly, terminal groove 11 is rectangular and be spaced on pedestal 10, terminal 14 is arranged in the

terminal groove

11,15 limited length that can extend of its elastic arm, the length of having only terminal groove 11, so its elasticity does not reach optimum state, especially under the situation that the function of CPU is more and more strong, its contact is also more and more many, so this pedestal 10 needs to arrange more terminal groove 14, make the length of terminal groove reduce, so 15 energy development lengths of elastic arm of terminal 14 also reduce, thereby it is bad and easy elasticity is tired general to form elasticity.

Summary of the invention

Main purpose of the present utility model is to provide a kind of electric connector, and the elastic arm of its terminal extends beyond fixed part one side, and the contact resilient that reaches terminal so can form the big arm of force is preferable.

Another main purpose of the present utility model is to provide a kind of electric connector, extends to fixed part one side by the elastic arm of terminal, and can reaching terminal, to be easy to make and take when assembling the space of terminal groove less.

For reaching above-mentioned purpose, the utility model electric connector, it includes: base, be spaced on it and be provided with many row's terminal grooves, this each terminal groove is provided with first groove and second groove, this second groove by first groove forward and be tilted to a side and extend to the first groove dead ahead with row's abutting end pilot trench, first groove of each terminal groove of each row is a straight line and arranges; And a plurality of terminals, it is provided with: fixed part, its plate face are first groove of longitudinal register in this terminal groove; Elastic arm, it is connected in fixed part upper end, and its plate face is vertically and becomes an oblique angle and exceed with the plate face of fixed part and extend on fixed part one side direction, and it is provided with contact near end, and it can be in second groove springing up and down of this terminal groove; And connecting portion, it is located at the fixed part lower end and extends downward the base lower end.

By above structure, the contact resilient of elastic arm that can reach terminal is preferable, be easy to make, and terminal to take the space of terminal groove when assembling less.

Above-mentioned and other purpose, advantage and characteristic of the present utility model by in the detailed description of following preferred embodiment and with reference to graphic when can be clearer.
