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 the detecting terminal 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 the detecting terminal, 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 detecting terminal of these prior aries generally includes a flexible terminal and a fixed terminal, and originally be between flexible terminal and fixed terminal and contact/off-state, after electronic cards is inserted, compress mobile terminal by the electronic cards leading edge, make flexible terminal and fixed terminal become disconnection/contact condition, thereby realize whether the detecting electronic cards has been inserted into the final position.But, can produce power that makes progress or component when the flexible terminal of existing detecting terminal and mobile termination contact, under the effect of the moment that this power produced, make flexible terminal in perpendicular, rotate easily, touch unreliablely indirectly, influence electric property thereby cause detecting terminal.

[summary of the invention]

The purpose of this utility model is to provide a kind of electronic card coupler that reliably connects between terminal of detecting.

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 detecting terminal in the insulating body, wherein detect terminal and comprise flexible terminal and fixed terminal, and flexible terminal connects in the crimping mode mutually with fixed terminal, and described flexible terminal is provided with the first roughly L-shaped holding parts.

Compared to prior art, flexible terminal in the utility model electronic card coupler detecting terminal is by being provided with the first roughly L-shaped holding parts, flexible terminal in the time of can preventing that flexible terminal and fixed terminal from connecting in the crimping mode rotates in perpendicular owing to be subjected to the rotating torque effect, thereby makes flexible terminal and fixed terminal reliably connect.

[embodiment]

Please refer to Figure 1 and Figure 2, the utility model electronic card coupler 1 comprises insulating body 10, conducting terminal 20, detecting terminal 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 second accepting groove 112 that the first roughly L-shaped accepting groove 110 and contiguous this first accepting groove 110 are provided with 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 simultaneously, 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).

Detecting terminal 30 is made up of flexible terminal 301 and fixed terminal 308, wherein flexible terminal 301 is provided with elastic portion 302, own elasticity portion 302 1 ends and is first linking arm 303 that tabular extends and contiguous elastic portion 302 and is vertically to first pressure contact portion 304 that first linking arm 303 is provided with, 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 the 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.

When electronic cards (not shown) was not inserted toward the 30 directions insertion of detecting terminal fully by slot 104 1 ends, first pressure contact portion 304 of flexible terminal 301 did not contact with second pressure contact portion 310 of fixed terminal 308; And when electronic cards is inserted fully, the electronic cards leading edge compresses the elastic portion 302 of flexible terminal 301 earlier, flexible terminal 301 activates first pressure contact portion 304, cooperation by first, second guidance part 305,309 makes first pressure contact portion 304 connect mutually in the crimping mode with second pressure contact portion 310 of fixed terminal 308, thereby whether the detecting electronic cards is inserted fully.
