[embodiment]

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

Refer to Fig. 1 to Fig. 3, the utility model electronic card coupler 100 have an insulating body 1, the some terminals 2 be installed in insulating body 1, the catch member 3 being fixedly arranged on insulating body 1 both sides, trip mechanism 4 and hide the shielding casing 5 on insulating body 1.Wherein, insulating body 1 and shielding casing 5 define formation one for accommodating the receiving space of drawout chassis 6.

Refer to Fig. 2 to Fig. 5, insulating body 1 is roughly in rectangular-shaped, its two side 12 having a diapire 11 and extend to form vertically upward along diapire both sides, the rear portion of insulating body 1 is convexly equipped with a boss 13 vertically upward by diapire 11, and this boss 13 is positioned at the side of diapire 11 in a lateral direction.Insulating body 1 is card insertion end away from one end of boss 13, described diapire 11 offers several terminal grooves 111, and terminal groove 111 arranges in two rows and runs through diapire 11.A sidewall 12 of insulating body 1 is formed with accepting groove 121 from top to bottom, and this accepting groove 121 is near the boss 13 at insulating body 1 rear portion.The middle part of above-mentioned sidewall 12 offers a slippage slot 123, described slippage slot 123 and accepting groove 121 to be positioned on same sidewall and to run through the plug-in card front end face of sidewall 12, and slippage slot 123 runs through diapire 11 downwards and is formed with rectangular spacing hole 124 being positioned at plug-in card end.The upper surface of described boss 13 projects upwards and is formed with a rotating shaft 131.On described insulating body 1, the opposite side relative with boss 13 is provided with a sense terminal pilot trench 14.

Terminal 2 comprises some signal terminals 21 and inspection terminal 23, and described signal terminal 21 is fixedly arranged in the terminal groove 111 of insulating body 1.Described inspection terminal 23 is roughly in bending structure, it has the fixed part 230 of a horizontal expansion, inspection terminal 23 is provided with contact site 231 towards the side of card insertion end, this contact site 231 protrudes in receiving space, fixed part 230 is positioned in the sense terminal pilot trench 14 at insulating body 1 rear portion, when electronic cards insert completely backward after push contact site 231.

Catch member 3 is roughly in an elongated metal sheet, and catch member 3 departs from middle bending certain angle and forms a kink (sign), and kink position is installed with ganoid latch part 31.Described catch member 3 is contained in the accepting groove 125 of insulating body 1 both sides setting, catch member 3 is immobilizated in the front end of corresponding accepting groove 125 to realize the location, front and back of catch member 3, it is interior for limiting the double swerve of the electronic cards after insertion that latch part 31 protrudes into receiving space, guarantees that electronic cards contacts with the stable of signal terminal 21.

Trip mechanism 4 mainly comprises plug-in card direction end mat push rod 41 that push rod 41 on the sidewall 12 being installed on insulating body 1 side and pivotable be installed on insulating body 1 to be promoted and executive item 42 that start rotates and then electronic cards released from receiving space, and wherein push rod 41 is bent to form by an elongated metal plate punching press.Described push rod 41 one end has been bent to form pressing portion 411, and push rod 41 is recessed to form fluted 412 from top to bottom away from the other end of pressing portion 411, lower surface outstanding formation one limiting section 413 downwards of push rod 41.

Described executive item 42 structure roughly in the form of sheets, wherein dig pivoting hole 421 in the middle part of executive item 42, executive item 42 away from one end of push rod 41 compared to that one end coordinated with push rod 41 in the longitudinal direction further from pivoting hole 421, so to make one end of executive item 42 be used for coordinating with push rod 41, the other end can be used for promoting to be equipped with towards card insertion end the drawout chassis 6 of electronic cards.The bottom surface of that one end that executive item 42 coordinates with push rod 41 is formed one and is lacked portion 423 after slimming process, because the existence in this scarce portion 423, the other end that executive item 42 is more relative with that one end that push rod 41 coordinates is thin.In the present embodiment, the slimming of executive item 42 realizes by forging and pressing, and formed after lacking portion 423, that one end that executive item 42 coordinates with push rod 41 is thinner, and executive item 42 is placed on after on push rod 41, and it protrudes from the height reduction of insulating body 1.

With reference to shown in Fig. 4, executive item 42 is positioned on the boss 13 at insulating body 1 rear portion, rotating shaft 131 on boss 13 is inserted in the pivoting hole 421 of executive item 42, push rod 41 is contained in the slippage slot 123 of insulating body 1, and can slide along electronic cards plug orientation in slippage slot 123, pressing portion 411 protrudes from outside insulating body 1 and operates for operator presses.Can be limited in the longitudinal direction by groove 412 in the groove 412 that the scarce portion 423 of executive item 42 is placed on push rod 41, thus realize push rod 41 and coordinate with the stable of executive item 42.Terminal part 424 horizontal expansion of that one end that executive item 42 coordinates with groove 412 enters in the accepting groove 121 of insulating body 1, and this terminal part 424 can slide along the longitudinal direction under the drive of push rod 41 in accepting groove 121.Can realize sliding along electronic cards plug orientation in the spacing hole 124 that the limiting section 413 of push rod 41 is contained in insulating body 1, thus the front and back realized when push rod 41 slides in slippage slot 123 are spacing.

During use, user is by promoting the pressing portion 411 on push rod 41, push rod 41 slides to plug-in card direction in slippage slot 123, sliding to plug-in card direction in that one end that the other end of push rod 41 drives executive item 42 to be mated by the groove 412 that it is arranged, makes executive item 42 rotate with rotating shaft 131 for axle center and then drive the other end of executive item 42 to card insertion end motion thus release the drawout chassis 6 that electronic cards is housed and move back card motion with realization.

Slimming process has been carried out in that one end that executive item 42 is coordinating with push rod 41 of the utility model electronic card coupler 100, thus makes the height reduction of this one end, and the whole height of electronic card coupler 100 can be made to reduce.
