[embodiment]
See also Fig. 1 to shown in Figure 2, the electric connector 100 of a preferable embodiment of the utility model electric connector is installed on printed circuit board (PCB) (not shown) and is used to be electrically connected chip module (not shown), and it includes insulating body 10 and plurality of terminals 20.Insulating body 10 is made by insulating plastics material, and it comprises some terminal grooves 11 that run through its end face and bottom surface, and terminal 20 is housed in the terminal groove 11.
In conjunction with shown in Figure 3, terminal 20 is made by sheet metal, and each terminal 20 comprises holding parts 21, elastic contact arm 22, weld part 23 and connecting portion 24.This holding parts 21 comprises first 211 and bends to be the second portion 212 that an angle is provided with first 211 from first's 211 1 sides, form a kink 213 between first 211 and the second portion 212, holding parts 21 integral body roughly are an arc shape.First 211 and second portion 212 are respectively equipped with the outer side edges that apical margin, root edge and are not connected with kink 213, each outer side edges is provided with a tab 25, thereby terminal 20 is fixed on the insulating body 10 by tab 25 and terminal groove 11 inwall interference engagement.
Described elastic contact arm 22 from second portion 212 apical margins of holding parts 21 upwards bending extend to form, this elastic contact arm 22 comprises that one is connected the adjutage 222 of roughly upwardly extending waveform elastic arm 221 and own elasticity arm 221 diagonally extendings with holding parts 21, and adjutage 222 terminal bendings have extended to form a contact site 223.Weld part 23 is bent to form from first's 211 root edges of holding parts 21.Tin ball 30 is arranged at weld part 23 belows, is used for terminal 20 is electrically connected to the printed circuit board (PCB) (not shown) of this electric connector 100 of aforementioned installation.Connecting portion 24 extends upward formation from first's 211 apical margins of holding parts 21, is used for being connected with strip (not shown).
Please in conjunction with Fig. 4 and shown in Figure 5, be provided with a projection 13 in the terminal groove 11 of insulating body 10, this projection 13 is positioned at terminal groove 11 lower ends.Terminal groove 11 comprises holding slot 110 and holding tank 112.Described holding slot 110 is used to accommodate holding parts 21, comprise the knee that is two sections of an angle setting and connects two sections, with structure corresponding to the holding parts 21 of terminal 20, the two side ends place of holding slot 112 is formed with a slit 114 respectively, thereby the holding parts 21 that is used to limit terminal 20 prevents that terminal 20 from rocking.Wherein a slit 114 is by the inwall institute common definition of aforementioned projection 13 with holding slot 110.Described holding tank 112 is used to hold elastic arm 221, roughly is sector space.
During assembling, each terminal 20 is arranged at respectively in the corresponding terminal groove 11 from top to bottom, the tab 25 of each terminal 20 by holding parts 21 interfered and is fastened on the inwall of terminal groove 11, and the adjutage 222 of each terminal 20 stretches out in, and terminal groove 11 is outer to be used for electrically contacting with chip module (not shown).The tin ball 30 that is arranged at weld part 23 is exposed to the bottom surface of insulating body 10.
Be compared to previous terminal structure, the ad hoc structure of the holding parts 21 of the terminal 20 of the utility model electric connector 100 by this type of terminal is had usually, the partial design that promptly is used to connect connecting portion 24 and elastic contact arm 22 is a holding parts 21, and need not between elastic contact arm and weld part, to set up in addition a holding structure, can obviously reduce the structure of terminal 20.And because the holding parts 21 of terminal 20 comprises first 211 and second portion 212, and first 211 and second portion 212 form an angle each other, the also corresponding design of the terminal groove 11 of insulating body 10, so the power of terminal 20 and insulating body 10 mutual interference engagement is present in two not on the direction of conllinear simultaneously, can effectively avoid terminal 20 to produce and rock, improve the location accuracy.
