[embodiment]

Describe the embodiment of the utility model electronic card coupler 100 in detail below in conjunction with accompanying drawing.

See also Fig. 1 and Fig. 2, the utility model electronic card coupler 100 has an insulating body 1, hide metal shell 2 on insulating body 1, be shaped in plurality of conductive terminals 3 and detecting terminal 4 in the insulating body 1, and install in the trip mechanism 5 of insulating body 1 one sides, wherein, insulating body 1 and metal shell 2 define the receiving space that formation one is used to accommodate electronic cards.

See also Fig. 2 and Fig. 3, metal shell 2 have the top board 21 of a rectangular plate shape and from top board 21 both sides respectively bending downwards extend to form a pair of relatively to the side plate 22 that is provided with, top board 21 compresses sheet 211 to having one respectively near card insertion end, compress sheet 211 and be used to compress the electronic cards of insertion, strengthen the downforce of electronic cards conducting terminal 3.Offer some block button holes 221 on the biside plate 22 respectively, described top board 21 is bent to form first baffle plate 232, second baffle 233 respectively downwards in the rear and front end of trip mechanism 5 one sides, wherein the second baffle 233 and first baffle plate 232 are relatively to be arrangeding in parallel, second baffle 233 place ends are card insertion end, described second baffle 233 outwards is bent to form a welding foot 25, and bending inwards along above-mentioned first baffle plate 232 is formed with corresponding breach on a holding part 242 and the insulating body (indicating) and matches; Above-mentioned top board 21 is bent to form an Extendible flake 231 along plug-in card direction end under the side direction away from trip mechanism 5.Bending inwards along Extendible flake 231 forms flexure strip 241, and flexure strip 241 upwards is bent to form contact chip 26 perpendicular to side plate 22 directions, and described contact chip 26 is relative to setting and parallel to each other with top board 21 with flexure strip 241.

Above-mentioned insulating body 1 comprises flat-platy base portion 11 and is located at the side wall 12 of base portion 11 both sides, wherein be formed with on the base portion 11 and be the plurality of terminals groove 111 that two rows are provided with, prolong outside the both walls 12 and be respectively equipped with some buckle pieces 121 and the corresponding one by one setting of above-mentioned block button hole 221, hold the positioning action that realizes insulating body 1 and metal shell 2 by the buckle piece 121 and the mutual button of block button hole 221.

Above-mentioned trip mechanism 5 mainly comprises a slide block 51, a guide bar 52 and a spring 53 that cooperates slide block to slide.Described slide block 51 1 ends offer a heart type groove 511 for guide bar 52 slips, and the other end is provided with the fixed leg 512 of a fixing spring 53.Trip mechanism 5 is a Push-Push type trip mechanism, and its operation principle is the prior art of industry, is not described in detail in this.Offer a mounting groove 112 of accommodating trip mechanism 5 on the described base portion 11, described trip mechanism 5 and detecting terminal 4 lay respectively at the both sides of insulating body 1.
