Abstract
An electric connector comprises a base, a plurality of terminal grooves arranged on the base in a spaced way and a plurality of terminals. Each of the terminal grooves is provided with two opposite first walls and two opposite second walls. The terminals are connected with a belt formed by stamping metal sheet, and are spaced terminals. Each terminal is assembled in the terminal groove on the bed, and is separate from the belt. The terminals are provided with sections and boards. Each of the terminals is provided with a fixed part, an elastic arm and a foot connecting part. The board is fixed close to the first wall of the terminal groove. The elastic arm is connected to the fixed part; the board extends aslant upwards towards the fixed part lengthways above the next terminal groove through the second wall; the position close to the terminal is provided with a connection point. The foot connecting part is arranged below the fixed part, and underlays to the bottom of the end. By adopting the above construction, the touch elasticity of the elastic arm of the terminal is excellent; the terminals are easy to manufacture; and the terminals occupy small space of the terminal grooves when the terminals are assembled.
Description
Technical field
The invention relates to a kind of electric connector, is the electric connector that contacts springing up and down about a kind of terminal particularly.
Background technology
The bottom surface of wafer (as CPU) is formed with several spaced contacts, and the electric connector that connects this pattern wafer is to utilize a downforce that wafer is fixed on the pedestal, guarantees to be electrically connected so as to the terminal Elastic Contact in contact that makes wafer and the terminal groove that is arranged in pedestal.
Seeing also Fig. 1, is a kind of electric connector of connecting wafer, and it is to be provided with: a pedestal 10, and arrange on it and be provided with several terminals groove 11; And several terminals 14, it is the terminal groove 11 that is arranged at this pedestal, and it is provided with the up and down elastic arm 15 and a fixed part 16 of springing, and this fixed part 16 is to fix with terminal groove 11 packings, this elastic arm 15 is connected in fixed part 16 upper ends, and its proximal end is provided with a contact 17 that protrudes.
When wafer 90 placed on the pedestal 10, each contact 91 of wafer 90 was contacts 17 of this each terminal 14 of contact; See also Fig. 2, when wafer 90 stressed pressing down, each terminal 12 is by the elasticity of elastic arm 15 and the receipts that contract, and this moment, contact 17 was that elasticity pushes against this contact 91 and reaches the electrical connection effect.
Knownly be configured with following shortcoming: promptly, terminal groove 11 is rectangular and is 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 may form the bad and easy elastic fatigue of elasticity.
Summary of the invention
The object of the present invention is to provide a kind of electric connector, the elastic arm of its terminal is the terminal groove that extends to the next door to fixed part one side, and the contact resilient that can reach terminal is preferable.
Another object of the present invention is to provide a kind of electric connector, is to extend 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.
A further object of the present invention is to provide a kind of electric connector, the elastic arm of its terminal near with the fixed part junction be provided with a longitudinal extension around bent circular arc, can reach when terminal groove closeer and make lateral length more in short-term, can be by this longitudinal extension obtain better elastic around bent circular arc.
A further object of the present invention is to provide a kind of electric connector, and the connecting point position of the elastic arm of this terminal is for two plate faces are folded to form, and makes this contact become arc surface but not section.
A further object of the present invention is to provide a kind of electric connector, and the first wall of this pedestal is provided with by the elastic arm that a projection is positioned at this terminal, by this projection really the normotopia terminal connecting point position about protection and can not rocking, make electrical contact correctly stable.
A further object of the present invention is to provide a kind of electric connector, and the elastic arm of this terminal is provided with fin near contact, makes near the bigger thickness of the one-tenth of contact, and is correctly stable so as to reaching electrical contact.
For reaching above-mentioned purpose, electric connector of the present invention, it includes: a base, be spaced on it and be provided with the several terminals groove, this terminal groove is provided with two relative first wall second walls relative with two; And several terminals, be to form by metallic plate punching that a strip is connected and spaced continuous terminal, each terminal is to be assembled in the terminal groove of this base and to separate with this strip, this terminal has section and plate face, this terminal is provided with: a fixed part, and its plate face is near the first wall location of terminal groove; And an elastic arm, it is connected in fixed part, and its plate face is vertical and is tilted to extend past second wall to next door terminal groove top toward fixed part one side direction, and it is provided with a contact near end; And a pin portion, it is located at the fixed part below 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.
