Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, relates in particular to a kind of electronic card coupler with precompressed conducting terminal structure.

[background technology]

People's Republic of China's utility model patent has disclosed a kind of electronic card coupler No. 02288057.7, it comprises insulating body and is contained in the interior plurality of terminals of insulating body that its terminal has an arc-shaped contact part, the U-shaped elastic portion from the extension of arc-shaped contact part one end, the holding parts that the own elasticity portion other end extends and the weld part that bends extension from holding parts downwards.One pressure section protrudes extension from the end of arc-shaped contact part to oblique below, and reflexed is inside.Be provided with the projection that the pressure section with terminal offsets in insulating body, and make elastic portion produce certain precompression.Along with light, thin, short, the little development trend of electronic equipment, the corresponding step-down of the height of insulating body and make the holding capacity of projection diminish, when the precompression of conducting terminal is big, can causes the buckling deformation of insulating body, thereby destroy the structure of electronic card coupler.

For fear of the problems referred to above, the utility model proposes a kind of new electronic card coupler to compensate its defect.

[utility model content]

The purpose of this utility model is to provide a kind of electronic card coupler with precompressed conducting terminal structure, and this prepressing structure is realized by the conducting terminal body.

The purpose of this utility model is achieved through the following technical solutions: a kind of electronic card coupler, it comprises insulating body and some conducting terminals that is contained in insulating body, described conducting terminal comprises a base portion, connecting portion from bending of base portion one end and extension, one end is connected on the connecting portion and is positioned at the contact site of base portion top and conducting terminal is immobilizated in holding parts on the insulating body, described contact site one end bending is also extended and the pre-splenium of formation to the one side at least, described base portion forms the stopper section that offsets and press with pre-splenium, makes precompressed portion be positioned at the below of stopper section.

Compared with prior art, electric connector of the present utility model has following beneficial effect: the pre-splenium by conducting terminal itself cooperates the realization precompressed with the stopper section, can reduce the height of whole electronic card coupler, and the firmly not fragile insulating body of this prepressing structure.

[embodiment]

See also Fig. 1 to shown in Figure 4, the utility model is a kind of electronic card coupler 100, it can be mounted on the printed circuit board (PCB) (not shown), and it comprises: insulating body 1, the some conducting terminal 2 of insulating body 1 and shielding casings 3 that matches with insulating body 1 of being contained in.

Described insulating body 1 is roughly rectangular, it comprises that the both sides of a main part 11 and autonomous body 11 extend upward the pair of sidewalls 12 of formation, be formed with some T-shaped terminal grooves 13 on the described main part 11, these terminal grooves 13 minutes two rows be provided with, comprise a cannelure 131 and a transverse groove 132, and the width of transverse groove 132 is big than the width of cannelure 131, so make terminal groove 13 T-shaped structures.Described sidewall 12 outer surfaces are provided with a groove 14.

Described shielding casing 3 is immobilizated on the insulating body 1, and both common electronic cards receiving spaces (not label) that form, a pair of vertical wall 32 that it comprises a horizontal wall 31, extend downwards from horizontal wall 31 both sides and the welding foot 33 that bends inwards and form by vertical wall 32, be provided with shell fragment 34 in described vertical wall 32, described shell fragment 34 is to the bending of electronic cards receiving space direction, and it is contained in the groove 14 of insulating body 1 when shielding casing 3 is installed on the insulating body 1; Described welding foot 33 can be soldered on the printed circuit board (PCB), is used for whole electronic card coupler 100 is installed fixing.

Described conducting terminal 2 inserts in the terminal groove 13 that is immobilizated in insulating body 1 from bottom to top, rubber-like connecting portion 22, the end that it comprises a base portion 21, extend from base portion 21 1 ends bendings be connected to connecting portion 22 and be positioned at the contact site 23 of base portion 21 tops, from contact site 23 terminal inwardly reflexeds and the pre-splenium 24 that extends to contact site 23 both sides, from base portion 21 both sides upwards the holding parts 27 that extends to form of bending, from base portion 21 1 ends extend upward and bend inwards stopper section 25 that forms and the weld part 26 that forms by base portion 31 downward punching presses.Described stopper section 25 along continuous straight runs extend internally, and it presses on the pre-splenium 24, make pre-splenium 24 be positioned at the below of stopper section 25, and described pre-splenium 24 and stopper section 25 are contained in the transverse groove 132 and realize precompressed.

The utility model electronic card coupler 100 reduces conducting terminal 2 precompressed by pre-splenium 24 and stopper section 25 height of whole electronic card coupler 100, and this precompressed effect is by the conducting terminal 2 pre-spleniums 24 that are provided with own and realize stopper section 25 and needn't rely on insulating body 1 to come precompressed conducting terminal 2, thereby not fragile insulating body 1.
