Description

Electronic card coupler

[technical field]

The utility model relates to a kind of electronic card coupler, relates in particular to a kind ofly electronic cards and circuit board are electrically connected and to have arrangement for detecting inserts state with the detecting electronic cards a electronic card coupler.

[background technology]

Usually borrow an electronic card coupler to be electrical connected between electronic cards and circuit board, and whether some electronic card coupler also is provided with arrangement for detecting, insert fully in order to the detecting electronic cards.The prior art relevant with the utility model, as United States Patent (USP) the 5th, 013,255,5,334,034,5,370,544 and 6,004, shown in No. 155 grades.The arrangement for detecting of these prior aries generally includes one and moves a terminal and a fixed terminal, and originally be between mobile terminal and fixed terminal and contact/off-state, after electronic cards is inserted, compress mobile terminal by the electronic cards leading edge, make mobile terminal and fixed terminal become disconnection/contact condition, thereby realize whether the detecting electronic cards has been inserted into the final position.But United States Patent (USP) the 5th as described above, 334,034 and 5,370, shown in No. 544, because the mobile terminal of these prior aries contacts with the realization on-off action in direct butt mode with fixed terminal, thereby mobile terminal easily elastic fatigue takes place in use for some time and can't return to initial condition to match with fixed terminal.

[summary of the invention]

The purpose of this utility model is to provide a kind of reliable and difficult electronic card coupler that produces the arrangement for detecting of elastic fatigue of contact that has.

The purpose of this utility model is achieved through the following technical solutions: the utility model electronic card coupler comprises that shielding casing, insulating body, group are located at conducting terminal and the arrangement for detecting in the insulating body, wherein arrangement for detecting comprises flexible terminal and fixed terminal, when electronic cards is inserted, the electronic cards leading edge compresses the elastic portion of flexible terminal, make flexible terminal connect mutually in slip crimping mode, thereby whether the detecting electronic cards is inserted fully with described fixed terminal.

Compared to prior art, the flexible terminal in the utility model electronic card coupler arrangement for detecting connects in slip crimping mode mutually with fixed terminal, thereby makes flexible terminal contact more reliable with fixed terminal and the difficult elastic fatigue that produces of flexible terminal.

[embodiment]

Please refer to Figure 1 and Figure 2, the utility model electronic card coupler 1 comprises insulating body 10, conducting terminal 20, arrangement for detecting 30, write-protect terminal group 40, trip mechanism 50 and shielding casing 60.Wherein insulating body 10 comprises diapire 101, the first side wall 102 and second sidewall 103, and diapire 101 is provided with some terminal containing slots 105 that run through its upper and lower surface, and be formed with slot 104 between described diapire 101 and two sidewalls 102,103, and be provided with first retaining wall 106 and second retaining wall 107 at slot 104 front ends.Offer first, second accepting groove 110,112 on first retaining wall 106, and its front surface is provided with first, second opening 111,113.In addition, the first side wall 102 middle parts are provided with breach 114, are provided with the groove 108 of accommodating trip mechanism 50 in order to accommodate write-protect terminal group 40, the second sidewalls 103.

In 20 groups of terminal containing slots 105 that are located on the insulating body 10 of conducting terminal, which is provided with contact site 201 and weld part 202, wherein contact site 201 protrudes from the upper surface of insulating body 10 diapires 101, and weld part 202 then can be welded on the circuit board (not shown).

Arrangement for detecting 30 is made up of flexible terminal 301 and fixed terminal 308, wherein flexible terminal 301 is provided with first pressure contact portion 304 that elastic portion 302, own elasticity portion 302 1 ends are first linking arm 303 that tabular extends and contiguous elastic portion 302 and are provided with perpendicular to first linking arm 303, and first linking arm, 303 1 ends are provided with the first roughly L-shaped holding parts 306, first holding parts, 306 1 ends also bend and are extended with first weld part 307, and wherein first pressure contact portion, 304 free ends upwards bend and are provided with first guidance part 305.In addition, described first linking arm 303 is from the oblique at an angle extension of first holding parts, 306 1 ends.

Fixed terminal 308 is provided with second pressure contact portion 310, is second linking arm 311 of tabular extension and second guidance part 309 that bending is provided with under second pressure contact portion, one side direction from second pressure contact portion, 310 1 ends, and second linking arm, 311 1 ends extend vertically downward and are provided with second holding parts, 313, the second holding parts, 313 1 end levels bendings and are extended with second weld part 312.

Trip mechanism 50 comprises and moves back card body 51, elastomer 52, push rod 53 and holding piece 54 that other structure and the function of this trip mechanism 50 are described by prior art, no longer describe in detail herein.

Please refer to shown in Figure 3ly, during assembling, first holding parts 306 of flexible terminal 301 is retained in first accepting groove 110 on insulating body 10 first retaining walls 106, and 307 of first weld parts pass first opening 111 and are welded on the circuit board.Second holding parts 313 of fixed terminal 308 is retained in second accepting groove 112 on first retaining wall 106, and 312 of second weld parts pass second opening 113 and are welded on the circuit board.Trip mechanism is adorned 50 and is assembled on second side arm 103, and shielding casing 60 is held on the insulating body 10.
