Abstract

The utility model relates to an electric connector terminal,. The electric connector terminal can be housed in the housing hole of the terminal of the insulating main body, including at least an elastic arm. The elastic arm deflecting and extending outward is fitted with the first stop part. When the terminal is pressurized, the first stop part can slide a certain distance within the terminal housing hole, and then prop against the inner wall of the terminal housing hole. The utility model of the electric connector is of simple construction, i.e. as the above mentioned, the elastic arm of the terminal deflecting and extending outward is equipped with the first stop par. The the first stop par can slide a certain distance when the terminal is pressurized, and then prop against the inner wall of the terminal housing hole, effectively improving the forwarding force of the terminal, and thereby allowing smaller contact resistance of the terminal and the butt-joint electric sets, while providing the effective contact of the terminal and the butt joint electric sets.

Description

Electric connector terminal

[technical field]

The utility model relates to a kind of electric connector terminal.

[background technology]

Development along with computer industry, CPU (Central Processing Unit, CPU), the structure of assemblies such as chip template and electric connector itself becomes increasingly complex, its function also from strength to strength, so it is also more and more higher to interconnective accuracy of each assembly and reliability requirement.Be the needs of coupling central processing unit, chip template and circuit board performance, the electric connector terminal that docks with it mostly is highdensity array telecommunication terminal.Thereby, the connected mode of industry-wide adoption at present be the ball bonding of grid type array tin connect (Ball Grid Array, BGA).But higher, the production inconvenience of cost that the electric connector that adopts the BGA mode now is bonding with central processing unit, chip template and circuit board, and it is bigger to make electric connector take volume owing to the welding and assembling height that is electrically connected is higher.Thereby industry is introduced pad grid array type (LandGrid Package, chip template packaged type LGP) again.Be the typical case of pad grid array type terminal structure as depicted in figs. 1 and 2, this terminal is provided with the contact site 10 that contacts with central processing unit or chip template etc., be provided with the weld part 30 that welds with tin ball 40 in the end of this terminal, this terminal sidepiece also is provided with can be against the stop section 30 of contact site 10, the overall structure more complicated, need repeatedly bending during moulding, and this termination contact portion strength is less, cause the conducting terminal positive force less, thereby cause contact resistance bigger, the image conducting terminal contacts with the effective of chip template.

Therefore, be necessary to design a kind of novel electric connector terminal, to overcome above-mentioned defective.

[utility model content]

It is a kind of simple in structure and can reduce the electric connector terminal of contact resistance that the purpose of this utility model is to provide.

To achieve these goals, the utility model electric connector terminal, can be placed in the terminal accommodation holes of insulating body, comprise at least one elastic arm, described elastic arm outwards bends to extend and is provided with first stop section, and first stop section can be resisted against on the inwall of terminal accommodation holes behind slippage one segment distance in terminal accommodation holes when terminal was stressed.

Compared with prior art, the utlity model has following advantage: the utility model electric connector terminal is simple in structure, and the elastic arm of terminal outwards bends to extend and is provided with first stop section, first stop section can be resisted against on the inwall of terminal accommodation holes behind slippage one segment distance in terminal accommodation holes when terminal was stressed, can effectively improve the positive force of terminal, thereby make terminal less with the contact resistance that docks electronic component, can guarantee that terminal contacts with butt joint the effective of electronic component.

[embodiment]

Below in conjunction with accompanying drawing the utility model electric connector terminal is described further.

See also Fig. 3 to Fig. 8, the utility model electric connector terminal 10 comprises first elastic arm 11 and second elastic arm 12, be provided with a junction 13 this two

elastic arm

11 and 12, by described first elastic arm 11 and second elastic arm 12 respectively outwards bending extend and be provided with first stop section 14 and second stop section 15, described first,

second stop section

14 and 15 is respectively and be provided with first contact site 16 and second contact site 17 between first, second

elastic arm

11,12.

Terminal 10 is placed in the insulating body 20, this insulating body 20 is provided with plurality of terminals accepting hole 21 and depression 22, terminal 10 is placed in the terminal accommodation holes 21, first stop section 14 also has a segment distance L from the inwall of terminal accommodation holes 21, and second stop section 15 is fastened in the depression 22 of insulating body 20, so that terminal 10 is fixed in the insulating body 20.When external connected electronic element 30 (as central processing unit or chip template etc.) and another electronic component 40 (as circuit board etc.) during respectively with 10 liang of end in contact of terminal, electronic component 30 contacts with junction 13 compressions of terminal 10, and another electronic component 40 contacts with 17 compressions with first, second contact site 16 of terminal 10.Terminal 10 is resisted against on the inwall of terminal accommodation holes 21 after being subjected to making first stop section, 14 skidding distance L after electronic component 30 normal pressures, this moment second stop section, 15 pressurizeds and being held in the depression 22 of insulating body 10.

The utility model electric connector terminal 10 is simple in structure, and the elastic arm of terminal outwards bends to extend and is provided with first stop section, first stop section can be resisted against on the inwall of terminal accommodation holes behind slippage one segment distance in terminal accommodation holes when terminal was stressed, can effectively improve the positive force of terminal, thereby make terminal less with the contact resistance that docks electronic component, can guarantee that terminal contacts with butt joint the effective of electronic component.
