Description

Electronic card coupler

[technical field]

The present invention relates in particular to a kind of electronic card coupler with terminal protection structure about a kind of electronic card coupler.

[background technology]

Development along with communication and digitalized electron technology, the capacity of the function of related device, required storage data and the requirement of electronic component miniaturization are got more and more, especially under the electronic component miniaturization requires, how to guarantee the electronic component stability and improve the production yield to seem particularly important.

The common electronics card connector, as Express card connector, though the link that its conducting terminal is connected with printed circuit board (PCB) is provided with fixed structure, but this fixed structure is only for being provided with a series of barrier blocks between conducting terminal, only to conducting terminal each other horizontal direction carried out partly isolating, they can't be at a plurality of orientation restriction conducting terminals.So in the installation moving process that electronic card coupler is mounted to printed circuit board (PCB), because terminal is more tiny and it is tight to arrange, under the situation that is subjected to the external force extruding, the link of conducting terminal very easily deforms or misplaces, to influence itself and the accuracy that is connected of printed circuit board (PCB), promptly the conducting terminal link can't accurately dock with corresponding pad on the printed circuit board (PCB).In addition, will make product rejection like this, increase production cost, and not meet electric connector and save cost, reliable and stable development trend.

For fear of the problems referred to above, the present invention proposes a kind of novel electron card connector to compensate its defect.

[summary of the invention]

The technical problem to be solved in the present invention provides a kind of electronic card coupler with terminal welding ends holding structure.

For reaching above-mentioned purpose, the invention provides a kind of electronic card coupler, it comprises insulating body, shielding casing, trip mechanism and plurality of conductive terminals, the insulating body front end face is provided with the plurality of fixed arm, shielding casing is covered on the insulating body and accommodates the receiving space of electronic cards with its formation, the insulating body front end face is provided with the plurality of fixed arm, conducting terminal is contained in the insulating body, it comprises clamping part, from the fixed part of clamping part bending downwards and at the terminal weld part that forms of fixed part, the width of wherein said conducting terminal clamping part and fixed part is greater than contact site and weld part.

Compared to prior art; electronic card coupler of the present invention has following effect: its fixed part that is provided with by conducting terminal is immobilizated in the holddown groove between the insulating body fixed arm; the protection conducting terminal is not subject to the external force extruding and is out of shape; improve the requirement of coplane degree simultaneously, improve product yield and good welding effect.

[embodiment]

Below, will introduce the embodiment of electronic card coupler of the present invention in conjunction with Fig. 1 to Fig. 4 in detail.Electronic card coupler 100 of the present invention comprises insulating body 30, be contained in conducting terminal 40, the shielding casing 10 in the insulating body 30 and be installed on the trip mechanism 20 of shielding casing 10 1 sides.Described insulating body 30 is accommodated and is installed on shielding casing 10 front end bottoms, and form thus by insulating body 30 and shielding casing 10 and be enclosed to form the receiving space (not label) of accommodating electronic cards, described trip mechanism 20 is installed on shielding casing 10 1 sides, finishes electronic cards and inserts the function that withdraws from.

See also Fig. 2 and shown in Figure 4, insulating body 30 comprises base portion 31, extract guid arm 33 that direction extends to form and extract direction from base portion 31 middle parts to electronic cards to electronic cards from base portion 31 two ends and extend to form tongue 34 between two guid arms 33, these tongue 34 inside connect forward and are formed with plurality of terminals accepting groove (not shown), be extruded with plurality of terminals fixed arm 32 at insulating body 30 front end faces, fixed arm 32 bottoms extend to form the terminal fixing grooves 322 that is formed with between 321, two holding sections 321, holding section with the corresponding connection of described terminal containing slot to both sides.

Conducting terminal 40 comprises contact site 41, clamping part 42, weld part 44 and the fixed part 43 of the connection weld part 44 that extends to form from clamping part 42 bending downwards and clamping part 42, and forms a kink 45 thus.Described contact site 41 and clamping part 42 pass the terminal containing slot of tongue 34 and accommodate in the insulating body 30, wherein contact site 41 is exposed to tongue 34 ends and electrically contacts with electronic cards (not shown), clamping part 42 is accommodated and is fixed in the terminal containing slot, and these clamping part 42 width are greater than contact site 41, the pars intermedia of clamping part 42 be symmetrical arranged a pair of draw-in groove (not label) be used for terminal containing slot in corresponding holding part (not shown) hold.Fixed part 43 is to form from clamping part 42 bending downwards, its width is suitable with clamping part 42 width, and greater than the width of weld part 44, forming step-like abutting part 431 with weld part 44 junctions thus, holddown groove 322 width between fixed part 43 and described two fixed arms 32 are roughly suitable.When conducting terminal 40 is accommodated into insulating body 30; the fixed part 43 of conducting terminal 40 is accommodated in the holddown groove 322 that is immobilizated between two fixed arms 32; abutting part 431 butts of fixed part 43 are lived the holding section 321 of fixed arm 32; limit the position, the left and right sides of conducting terminal 40 by both sides fixed arm 32; limit the upper-lower position of conducting terminal 40 by abutting part 431 butt holding sections 321; like this; terminal fixing grooves 322 is with fixed part 43 multi-faceted the enveloping of conducting terminal 40; avoided the interference of external object to conducting terminal 40; thereby protection conducting terminal 40 can not be out of shape impairedly because of external force, has improved the product yield.

Compared to existing electronic card coupler; the fixed part 43 of electronic card coupler 100 of the present invention by conducting terminal 40 is coated in the holddown groove 322 between insulating body 30 fixed arms 32; protected conducting terminal 40 in producing moving process, can not make its distortion dislocation because of being subjected to external force; improved the requirement of coplane degree simultaneously; and then; good welding effect is provided, guarantees the connective stability energy of itself and printed circuit board (PCB).Certainly, fixed part 43 also can be made of the part of a plurality of different in width.
