100a or limit assembly realize locking with spacing it is also possible to the diverse location in fitting recess 100 arranges at least two locked components
100a or limit assembly are realized locking and spacing.
Wherein, described locked component 100a includes being arranged on card falcon guide groove 101 on extension housing 900, spacing slip is joined
It is combined in and stirs card falcon 102, the clamping position 201 being correspondingly arranged on replaceable component 200 in card falcon guide groove 101, described stir
Card falcon 102 inserts the replaceable component 200 that clamping position 201 is locked in fitting recess 100, stirs card falcon 102 and exits clamping position 201
Unlock.Clamping position 201 is arranged on grafting base 205, blocks falcon guide groove 101 and stir card falcon 102 in locked component 100a
The direction of motion of the direction and replaceable component 200 disengaging fitting recess 100 of insertion clamping position 201 vertical so that stirring card falcon 102
Insertion clamping position 201 prevent replaceable component 200 along fitting recess 100 lengthwise movement.It is arranged on expansion in locked component 100a
Exhibition housing 900 side plate on when, described card falcon guide groove 101 be arranged on extension housing 900 side and with fitting recess 100 vertically through.
Specifically, described card falcon guide groove 101 includes guide groove cell body and the closing guide groove cell body on recessed extension housing 900 surface
Shrouding, described shrouding and guide groove cell body form accommodating and slide and stirs the cavity of card falcon 102, and the length of this cavity is not less than group
The move distance sum of card falcon 102 is stirred when the length of dynamic card falcon 102 and locking.Shrouding is demountable structure；Shrouding is permissible
Substituted using extension housing 900, need not separately set, described shrouding is provided with spacing hole 109, the effect of spacing hole 109 is used for determining
Locking and unlocked position.Described stir the shifting block that card falcon 102 is provided with and slide 108 cooperations in described spacing hole 109, shifting block is slided
Card falcon 102 locking replaceable component 200, shifting block slip 108 to spacing hole 109 other end are stirred in dynamic 108 to spacing hole 109 one end
Release the locking to replaceable component 200.Card falcon guide groove 101 and extension housing 900 integrative-structure, or the two Split type structure is simultaneously
It is fixed together.
Clamping position 201 on described replaceable component 200 is buckling groove or the clamping being arranged on replaceable component 200
Hole, the described buckling groove as clamping position 201 or blocked hole correspondence are stirred card falcon 102 and are arranged.When replaceable component 200 is assemblied in
In fitting recess 100, then the clamping position 201 of replaceable component 200 and the relative insertion of card falcon guide groove 101, are beneficial to and stir card falcon 102
Insertion clamping position 201.Clamping position 201, along the direction of motion setting stirring card falcon 102, is preferably perpendicular to replaceable component 200 and indulges
To setting, buckling groove is the groove opening up on grafting base 205 surface of replaceable component 200, and the depth of buckling groove is not to destroy
Grafting base 205 bulk strength is simultaneously defined enough to lock replaceable component 200.Buckling groove horizontally set on grafting base 205,
Perpendicular with the direction of insertion of grafting base 205.Blocked hole is the hole being arranged on grafting base 205 side, laterally at grafting bottom
Arrange on seat 205, blocked hole can be through hole can also be blind hole.Insert clamping position 201, preferably clamping position 201 for convenience
I.e. buckling groove or blocked hole are provided with abducent guiding port, the larger guiding port of opening seamlessly transit to buckling groove with wall or
In blocked hole.
In the present embodiment, clamping position 201 is chosen as buckling groove, and buckling groove is arranged on the surface of grafting base 205, clamping
Groove be shaped as straight trough, be easy to directly from the insertion of the end of buckling groove, the shape of cross section of buckling groove is multiple, in order to avoid dialling
The abjection of dynamic card falcon 102, the preferably width of rebate of buckling groove are less than the transverse width stirring card falcon 102 so that the groove of buckling groove
Mouth will stir card falcon 102 spacing avoid abjection.
As shown in Figure 3 a, when described stir card falcon 102 be allocated to unblock when, described stir card falcon 102 and be not inserted into
Described buckling groove, now described grafting base 205 can slide freely in described fitting recess 100.
As shown in Figure 3 b, when described stir card falcon 102 be allocated to locking when, described stir card falcon 102 insert described
Buckling groove, now described grafting base 205 stirred card falcon 102 and hinder by described, be locked in described fitting recess 100, this
When complete locking to described grafting base 205.
Stir, by described, one side that card falcon 102 is allocated to unblock in the same manner, described stir card falcon 102 and no longer hinder described grafting bottom
The slip of seat 205, now completes the unblock to described grafting base 205.
When locked component 100a cannot directly limit replaceable component 200 abjection, can select to limit using limit assembly
Replaceable component 200 processed is deviate from from fitting recess 100.Spacing and locking can also be directly realized by using locating part.I.e. spacing group
The structure of part has a kind of multiple, structure using increase, and that is, the notch in fitting recess 100 arranges locating part, and another kind is exactly to adopt
With fitting recess 100 itself as limit assembly.
Increase structure be exactly：Described limit assembly is the tumbler being arranged on fitting recess 100 notch, and described tumbler turns
It is automatically connected on extension housing 900, block fitting recess 100 restriction replaceable component 200 after rotation and deviate from；
Fitting recess 100 itself is as limit assembly：Described locating part is the notch of fitting recess 100, described fitting recess 100
Width of rebate is less than groove insied width, and described notch limits replaceable component 200 and deviates from, for example with notch little trapezoidal, circular arc
Shape etc..
In the present embodiment, being shaped as of described fitting recess 100 is one trapezoidal, and the inner corner trim of trapezoidal internal all does chamfered, its
Narrow side is located at extension housing 900 back surfaces, forms notch as limit assembly.Fitting recess 100 itself is as limit assembly
Have the beneficial effects that：Stress in the vertical direction of terminal back can decompose a part in the notch inwall by fitting recess 100
To horizontal direction, mechanical structure is more firm.The side opening of described fitting recess 100 can be arranged at extension any side of housing 900
Side and be not limited to the example of the present embodiment.The post-positioned pick-up head of mobile terminal is arranged on the vertical of the middle part of described fitting recess 100
On line, such structure can be easy to extend the hardware capability relevant with post-positioned pick-up head.
