See also Fig. 3 to shown in Figure 5, trip mechanism 50 comprises a pedestal 51, an elastic parts 52, a guide pins 53 and a sheet metal 54, described pedestal 51 is the stripe shape bulk, is assembled in a support arm 12 sides of insulating body 10 near way block 40, and its lateral surface is provided with wholeheartedly type guide groove 510.Pedestal 51 is provided with the support portion 512 that above-mentioned perforate 511 and is positioned at its bottom outside, and described support portion 512 is used for support elastic assembly 52 and sheet metal 54, which is provided with an elongated slot 513 that is used to guide sheet metal 54.Described sheet metal 54 slidably is assembled on the insulating body 10, can be along sliding on electronic cards 100 insertions and the exit axis.Described elastic parts 52 is a spring, and one end button is held on the guide pins 53, and other end button is held in one on the shell fragment 314 (seeing also shown in Figure 1) of upper shell 31 edges extension downwards.Guide pins 53 is formed by the bending of Metallic rod two ends, and wherein preceding end is fixed on the sheet metal 54, and back end slidably places in the heart type guide groove 510.Sheet metal 54 has a preload position and a position latching along the definition of electronic cards 100 direction of insertion.Sheet metal 54, with tensile elasticity assembly 52, drives guide pins 53 and slides until being locked in described position latching in heart type guide groove 510 when electronic cards 100 direction of insertion move from preload position.Promote sheet metal 54 once more and will remove breech lock, under the effect of elastic parts 52, drive sheet metal 54 and get back to preload position.

To describe the structure of sheet metal 54 below in detail, sheet metal 54 is made by a sheet metal, and it comprises that a vertical piece 540 that is used for fixing guide pins 53 reaches from the inside horizontally extending horizontal part 541 of vertical piece 540 upper limbs.The trailing edge bottom of vertical piece 540 extends back an adjutage 548; The leading edge inboard of horizontal part 541 is provided with one and moves back card arm 542, the trailing edge inboard button gripping arm 543 that extended back, and leading edge middle part is formed with one and the fairlead 544 that extends along electronic cards 100 direction of insertion downwards.Described move back card arm 542 and buckle gripping arm 543 all extend in the receiving space 200 directly to cooperate with electronic cards 100, in the middle of the support arm 12 that fairlead 544 inserts insulating bodies 10 and the pedestal 51, be used for guide wire sheet 54 and move along the insertion and the exit axis of electronic cards 100.Also can slide in the elongated slot 513 of adjutage 548 insertion pedestals 51 supporting brackets 512 along elongated slot 513.

In conjunction with shown in Figure 6, electronic cards 100 front ends are provided with the host cavity 101 that can accommodate the hyoplastron 13 of insulating body 10, are provided with the conductive spacer (not shown) that terminal 20 some and this electronic card coupler electrically connects in the host cavity 101.Electronic cards 100 upper surfaces have been recessed to form a recess 102 downwards in the position near host cavity 101.The button gripping arm 543 of sheet metal 54 comprises the end 547 that a cantilever 545 and extends back roughly V-shaped holding part 546 and extends back from holding part 546 levels from cantilever 545.Holding part 546 is used for cooperating with the recess 101 of electronic cards 100.Terminal 547 are provided with a pair of alar part that extends laterally (not label), make end 547 be provided with one and have the part of Breadth Maximum.

The opening 316 of upper shell 31 is made of the front and back rectangular channel of two connections, and wherein the back rectangular channel is that width is big slightly than the size of preceding rectangular channel on side direction.When sheet metal 54 is positioned at preload position, the cantilever 545 of its button gripping arm 543 is corresponding with the preceding rectangular channel of opening 316, terminal 547 is corresponding with the back rectangular channel of opening 316, and terminal 547 Breadth Maximum is less than the width of back rectangular channel, and the width of cantilever 545 and holding part 546 is also less than the width of preceding rectangular channel.So the cantilever 545, the holding part 456 and terminal 547 that are positioned at this position all can pass opening 316 and move up.In addition, terminal 547 Breadth Maximum is greater than the width of preceding rectangular channel, so when terminal 547 are positioned at preceding rectangular channel below, it can't pass opening 316 and move up.

When sheet metal 54 is positioned at preload position, electronic cards 100 is inserted in receiving space 200 processes at it, the holding part 546 that its front end will upwards promote to detain gripping arm 543 makes cantilever 545 that deformation take place, and cantilever 545, holding part 546 and terminal 547 will move up by the opening 316 of upper shell 31.When electronic cards 100 touch sheet metal 54 move back card arm 542 time, under the effect of the recovery elastic force of cantilever 545, holding part 546 enters in the recess 102 of electronic cards 100.Electronic cards 100 drive sheet metals 54 slide together afterwards.When electronic cards 100 and sheet metal 54 are latched in position latching, terminal 547 are positioned at opening 316 preceding rectangular channel belows, because terminal 547 parts that have Breadth Maximum can't be passed this preceding rectangular channel, and then limited moving up of holding part 546, so holding part 546 promptly is locked in the recess 102 of electronic cards 100, avoided being extracted by mistake in this position latching electronic cards 100.When moving back card, electronic cards 100 can be pulled out after getting back to preload position freely.
