Abstract
An electric connector terminal, from the top to the bottom, is stored inside the insulating body of an electric connector to provide the electrical connection between a chip module and a circuit board. The electric connector terminal comprises a base and arm parts. The base consists of a main body, a holding part and a welding part, and the holding part is provided thereon with a reinforcement part. The arm parts extend out of the opposite side edges of the main body.
Description
[technical field]
The utility model relates to a kind of electric connector terminal, relates in particular to a kind of electric connector terminal that chip module is electrically connected to circuit board.
[background technology]
The existing electric connector terminal that is used to electrically connect chip module and circuit board, generally comprise body, from terminal arm that body extend to be provided with, from the contact site of the electric connection chip module that the terminal arm extends and from extend on the body with circuit board on the corresponding weld part of electric conductor.This terminal arm comprises adjutage that is provided with from the body extension and the linking arm that connects adjutage and contact site.During use, the stitch of chip module inserts by the terminal arm and surrounds in the host cavity that forms, and matches with the contact site of conducting terminal, thereby realizes the electric connection between conducting terminal and chip module and the circuit board.
Announce the 6th, 319 as United States Patent (USP), the electric connector terminal 1 shown in No. 038, the weld part 14 that it comprises body 12, extends the pair of terminal arm 20 that is provided with from body 12 both sides and be positioned at body 12 bottoms.This terminal arm 20 comprises upper arm 21 that is provided with from body 12 extensions and the forearm 25 that connects upper arm 21 and contact site 27, and body 12 belows are provided with holding parts near the weld part place, and holding parts is provided with hangnail 121.Yet, along with the miniaturization of electric connector, highdensity development trend, spacing between the electric connector terminal is more and more little, the terminal arm is if be shortened the elastic force that then can influence terminal, influence combines with chip module, so in order to keep the elastic force of terminal, the adjutage of terminal arm certainly will be extended downwards with lengthening terminal length, but, this will influence the design space of the hangnail on the holding parts, thereby when influencing terminal and inserting insulating body and the retain strength between the insulating body, and then influence electric connection between terminal and the chip module.
Therefore, be necessary to design a kind of electric connector terminal that overcomes above-mentioned defective.
[utility model content]
Technical problem to be solved in the utility model is to provide a kind of electric connector terminal that can strengthen the terminal retain strength.
For addressing the above problem, the utility model adopts following technical scheme: a kind of electric connector terminal, be contained in from top to bottom in the insulating body of electric connector, electric connection between chip module and the circuit board can be provided, it comprises matrix and terminal arm, matrix comprises body, holding parts and weld part, and holding parts is provided with rib, and the terminal arm extends from the relative side of body.
Compared with prior art, the utility model electronic card coupler has following beneficial effect: electric connector terminal is provided with trapezoidal rib in holding parts, strengthened the root structure of hangnail, improve the bracing force of hangnail, strengthened electric connector terminal and be immobilizated in retain strength in the insulating body, produced when avoiding terminal from up to down to be assembled in the insulating body of electric connector and destroy.And the space that the trapezium structure of rib can fully provide the adjutage of electric connector terminal to extend downwards, make adjutage not can with the holding parts interference, and then guarantee the design and the fixing function of hangnail.

Fig. 2 is the stereogram of another angle of the utility model electric connector terminal.
Fig. 3 is the front view of the utility model electric connector terminal.
[embodiment]
See also Fig. 1 to shown in Figure 3, the utility model electric connector terminal 1 is mainly used in chip module (not shown) is electrically connected to circuit board (not shown), and this electric connector terminal 1 comprises matrix 10 and the pair of terminal arm 20 that links to each other with matrix 10 one.
The holding parts 13 of electric connector terminal 1 of the present utility model extends upward in hangnail 132 tops and is provided with trapezoidal rib 133, strengthened the root structure of hangnail 132, improve the bracing force of hangnail 132, strengthened electric connector terminal and be immobilizated in retain strength in the insulating body, produced when avoiding terminal 1 from up to down to be assembled in the insulating body of electric connector and destroy.In addition, along with the miniaturization of electric connector, highdensity development trend, spacing between the electric connector terminal is also more and more little, in order to keep the elastic force of terminal, the ancon 22 of adjutage 21 ends must extend downwards with lengthening terminal length, provides the terminal arm enough flexibilities, the space that the trapezium structure of the utility model rib 133 can fully provide the adjutage of electric connector terminal to extend downwards, so adjutage not can with the holding parts interference, and then guarantee the design and the fixing function of hangnail.During assembling, electric connector terminal 1 is from up to down packed in the insulating body by the guiding of the guidance part on the holding parts 13 131, by chip module being applied a pressing force, make the stitch of chip module strut the contact site 24 of electric connector terminal 1, at this moment, the adjutage 21 generation strains of electric connector terminal 1 expand outwardly and make stitch insert in the receiving space of terminal arm 20 formation with low insertion force, cooperatively interact after between a pair of contact site 24 of the electric conductor insertion electric connector terminal 1 of chip module and with it, the hangnail 122 of body head 12 and the hangnail 132 of holding parts 13 provide the retain strength between electric connector terminal and the insulating body, trapezoidal rib 133 is further strengthened hangnail 132 and is immobilizated in the interior retain strength of insulating body, produce when avoiding terminal 1 assembling and destroy, thereby realize electric connector terminal 1 and the firm electric connection of chip module, at last weld part 14 is soldered to printed circuit board (PCB).
