22 connect with the interference fit of housing 11 so that can precompressed be carried out by sealing ring 22 between housing 11 and keying body 21, with
The gap of through-hole 12 between housing 11 and keying body 21 is filled up, ensures that the inside of mobile terminal and outside are completely isolated, it is mobile
Any direction of terminal directly will not be entered inside by the injection of water.
Wherein, it is negative that interference, which is the difference that the size of finger-hole subtracts the size of matched axis,.
Interference fit refers to have the cooperation of interference (being equal to zero including minimum interference), and the tolerance range in hole is in the tolerance range of axis
Under, the size in all directions in hole subtracts the algebraic step obtained by the size in all directions of matched axis, this difference is
It is interference fit when negative.
Interference fit connection is the connection being interference fitted to realize using two connected pieces in itself, according to interference volume
Size can make releasable connection, may be alternatively configured non-disconnectable connection, and mating surface can be cylindrical surface, also be sometimes circular conical surface, assembling
Afterwards, the radial deformation of external member and internal member makes to generate very big pressure between mating surface, during work, rubs by what pressing force generated
Power is wiped to transmit load.
In the utility model embodiment, the housing 11 of mobile terminal is provided with the through-hole 12 interted for Waterproof push-button, prevents
Water button includes the sealing ring 22 of keying body 21 and surrounding key ontology 21, and Waterproof push-button is by through-hole 12 by sealing ring
22 connect with the housing 11 of mobile terminal interference fit, so as to form totally enclosed waterproof construction, realize high-level waterproof,
And reduce waterproof construction and space is occupied, improve the quality of mobile terminal.
As a kind of preferable example, sealing ring 22 can pass through the modes such as dispensing or adhered by double sided plaster and 21 knot of keying body
It closes, sealing ring 22 can be a kind of soft medium that can be compressed, and cost is relatively low, and soft medium can pass through injection process.
Sealing ring 22 can be made of following any material：
Silica gel, liquid silica gel, thermoplastic polyurethane elastomer rubber (Thermoplastic polyurethanes,
TPU)。
In a kind of preferred embodiment of the utility model, sealing ring 22 is in the thickness not being interference fitted with housing 11 when connecting
Degree is more than by the distance between circular keying body 21 and housing 11, so as to ensure that by the circular keying body of sealing ring 22
Shrink value, such as Fig. 3 are formed between 21 and through-hole 12, it is close after keying body 21 is assembled with sealing ring 22, then in housing 11
Seal 22 can form interference fit connection with housing 11.
As a kind of example, the shrink value of sealing ring 22 and the interference fit connection of housing 11 can be 0.03 millimeter to 0.35
Between millimeter.
In a kind of preferred embodiment of the utility model, Waterproof push-button can also include boss 23, and boss 23 can be
Keying body 21 and the direct contact surface of microswitch 13, one end that boss 23 is inserted into housing 11 with keying body 21 are connect.
As a kind of example, the cross-sectional width of boss 23 can be between 0.2 millimeter to 4.0 millimeters.
Boss 23 can be the shapes such as ellipse, semicircle, rectangle.
The making material of boss 23 can be identical with keying body 21, and can be integrally formed with keying body 21, also may be used
Think that the materials such as silica gel, liquid silica gel, thermoplastic polyurethane elastomer rubber are made, and bonded with case ontology 21.
In a kind of preferred embodiment of the utility model, mobile terminal can also include microswitch 13, such as FK components,
Microswitch 13 is located at the lower section of Waterproof push-button, and such as Fig. 4, when pressing Waterproof push-button, boss 23 is contacted with microswitch 13, with
Microswitch 13 is squeezed, realizes the unlatching of microswitch 13.
It should be noted that when pressing Waterproof push-button, boss 23 can be contacted directly with microswitch 13, can also be led to
It crosses and squeezes other devices, so as to be contacted indirectly with microswitch 13.
In a kind of preferred embodiment of the utility model, through-hole 12 can have step, and such as "T"-shaped, through-hole 12 is close
The cross-sectional width of 13 side of microswitch is less than the cross-sectional width of opposite side.
Correspondingly, keying body 21 can also have step, keying body 21 is close to the cross section of 13 side of microswitch
Width is less than the cross-sectional width of opposite side, since through-hole 12, keying body 21 are front wide and rear narrow, when pressing keys ontology 21
When, keying body 21 can be pressed down close to 13 side of microswitch, and the opposite side of keying body 21 can't be pressed completely, from
And realize the effect of limiting.
In a kind of preferred embodiment of the utility model, Waterproof push-button can also include blocking the Clip Reed of boss 23
24, such as Fig. 5, Clip Reed 24 can be " C " type, and by the fixed function of Clip Reed 24, multiplexing boss 23 is and microswitch 13
The contact of contact, without again by stent come solder contacts.
It is connected specifically, Clip Reed 24 can be interference fitted with boss 23, Clip Reed 24 is connected with the interference fit of boss 23
The sum of thickness afterwards can be more than cross-sectional width of the through-hole 12 close to 13 side of microswitch, when external force pulls out Waterproof push-button outward
When, due to the effect of Clip Reed 24, Waterproof push-button cannot be pulled out.Waterproof push-button is fixed on mobile terminal so as to ensure that
In.
