Stating the position of the face of electric connector 30, the gland portion 41 can apply gland power to second connecting seat 22, and described second
Connecting seat 22 is acted on by gland power and closely contradicted with first connecting seat 21.In the end face of the second bottom 221 and described the
During the angle at an acute angle of the end face of one top 212, the pressing plate 40 is located at the mainboard 10 close to the position of the rotating shaft 225, described
Distance be present in pressing plate 40 and the electric connector 20, two connecting seat 22 can relatively described first connecting seat 21 overturn；Institute
State pressing plate 40 to slide towards close to the direction of electric connector 20, second connecting seat 22 is connected with first connecting seat 21
One end first slip between the gland portion 41 and the mainboard 10, second connecting seat 22 can not continue relatively described first
Connecting seat 21 is opened；The gland portion 41 is slided towards with the position of the face of electric connector 20, the He of the second connecting seat 22
Gradually relatively described pressing plate 40 slips between the gland portion 41 and the mainboard 10 first connecting seat 21, the gland portion
The gland power of 41 pairs of second connecting seats 22 gradually increases, and finally causes the second connecting seat described in the gland of gland portion 41
22, second connecting seat 22 and the tight closure of the first connecting seat 21.
In one embodiment, referring to Fig. 10, the bending part 42 has the sliding edge for the chute 12 that is slidably connected
Edge 43.As shown in Fig. 2 when the pressing plate 40 slides into the predeterminated position, the second connection described in the gland of gland portion 41
Second top 222 of seat 22.The substantially vertical mainboard 10 of bending part 42.Connected in the gland portion 41 to described second
During 22 gland of seat, the bending part 33 is located at the both sides of the electric connector 20 respectively.The sliding edge 43 is slidably connected institute
Chute 12 is stated, and the sliding edge 43 is provided with the slip flange 44 coordinated with the stopper slot 16.
Further, as shown in figure 11, the gland portion 41 is provided with projection 411 towards the side of mainboard 10；Described
When pressing plate 40 slides into the predeterminated position, described raised 411 are held in second connecting seat 22 and first connecting seat
21 phases deviate from side.
In present embodiment, on the second top 222 described in the gland of gland portion 41, described raised 411 contact at it is described
Second top 222.The local pressure increase on raised 411 pairs of second tops 222 so that second connecting seat 22 is right
First connecting seat 21 contradicts even closer.Described raised 411 can be the substantially face geometry positioned at the gland portion 32
Center so that described raised 411 can apply pressure to the substantially geometric center of the end face of the second top 222 so that
The conflict power equiblibrium mass distribution that second connecting seat 22 applies to first connecting seat 21.It can also be described raised 411
The array distribution in the gland portion 41 so that the multiple spot position stress of the second top 222.
Further, Figure 12 and Figure 13 are referred to, described raised 411 be bending elastic arm, described raised 411 pairs described
Two connecting seats 22, which apply, flexibly supports power.
In present embodiment, the gland portion 41 is additionally provided with through hole 412.Described raised 411 include the He of bending free end 413
The fixing end 414 that relatively described bending free end 413 is set.The fixing end 414 is fixed on gland portion 41 in the through hole 412
Edge, the bending free end 413 is extended in the through hole 412.The bending free end 413 can be along the through hole
Move back and forth on 412 opening directions.At the second top 22 described in the 41 non-gland of gland portion, the bending free end 413
The through hole 412 is exposed in part, and described raised 411 be in nature extended position.On the second top described in the gland of gland portion 41
When 222, the bending free end 413 houses the through hole 412, and described raised 411 are resilient deformed state.Described raised 411
Elastic conflict power is applied to second top 22.The bending free end 413 is in hook solid.The bending free end 413 has
There is circular arc camber, slided in the relatively described mainboard 10 of the pressing plate 40, the circular arc camber of the bending free end 413 contacts at institute
The end face of the second top 222 is stated, reduces the slip damping force to the bending free end 413, is reduced to second connecting seat 22
Damage.
In another embodiment, as shown in figure 14, described raised 411 be semispherical silicon rubber cushion.Pressed in the gland portion 41
When covering second top 222, described raised 411 are squeezed force deformation, and raised 411 pairs of second connecting seats 22 apply
Elastic conflict power so that second connecting seat 22 closely contradicts with first connecting seat 21.
Further, Figure 15 is referred to, second connecting seat 22 is set with the phase of the first connecting seat 21 away from side
There is the guide groove 226 of the vertical pivot center of second connecting seat 22, described raised 411 are slidably matched with the guide groove 226.
In present embodiment, the almost parallel length direction of second connecting seat 22 extension of guide groove 226.It is described to lead
Opening is set to groove 226 on the end face of the second top 222, and in second connecting seat 22 close to the rotating shaft 225
Side on set opening so that described raised 411 can slip into the guide groove 226, and described raised 411 can be in institute
State in guide groove 226 and slide.After described raised 411 slip into the guide groove 226, raised 411 pairs of second connecting seats
22 apply conflict power at the bottom surface of the guide groove 226.Second guide groove 226 is kept away raised 411 slide-and-guide
Exempt from described raised 411 by resistance and relatively described second connecting seat 20 produces dislocation, prevent the pressing plate 30 from damaging.
Further, the guide groove 226 has slips into end 2261 and phase close to the rotary shaft of the second connecting seat 22
The positive stop end 2262 set to the sliding end 2261, described raised 411 slip into the guide groove along the end 2261 of slipping into
226, the positive stop end 2262 is spacing to described raised 411.
In present embodiment, the end 2261 of slipping into is arranged at second connecting seat 22 close to the rotary shaft 224
Side wall.The positive stop end 227 slips into end 2261 away from described.The positive stop end 2262 can be the closing of the guide groove 226
End.The positive stop end 2262, which limits described raised 411, to be continued to slide towards away from the direction for slipping into end 2261.In the projection
During the position that 411 slips contradict as the positive stop end 2262, the second connecting seat 22 described in the face of gland portion 41 so that institute
State firm pressing second connecting seat 22 in gland portion 41.
Further, Figure 16 is referred to, the depth of the guide groove 226 holds 226 to the positive stop end by described slip into
Gradually increase at 227.
In present embodiment, the relatively described end slope of second top 222 in bottom surface of the guide groove 226.The projection
411 226 are slided by the end of slipping into towards the positive stop end 227, and the bottom surface of the guide groove 226 is overstock to described raised 411
Deformation gradually increases so that the conflict power of raised 411 pairs of second connecting seats 22 gradually increases, that is, facilitates the gland
Portion 41 slides into the position of the second connecting seat 22 described in gland.
Further, Figure 17 is referred to, the electrical connector 100 also includes fixture 60, and the fixture 60 is in institute
