Description
Technical field
The present invention relates to switching technique fields, more particularly to the breather hole structure and its switch of a kind of switch.
Background technology
Switch is widely used in the control circuit of various equipment, in order to seal internal structure, to prevent outside
The influence to inner components of water, moisture, switch is usually realized into sealing with plastic packaging glue, and to reach solidification logical for plastic packaging glue
It often needs to bake a period of time at high temperature, thus needs that an air hole is in addition arranged on the shell of switch, to ensure
The identical solidification without influencing plastic packaging glue of inner and outer air pressure, seals after plastic packaging adhesive curing, then by air hole.Fig. 1, Fig. 2 are
The breather hole structure of a kind of breather hole structure of switch of the prior art, the switch includes pedestal 100 and cover board 200, in pedestal
100 are equipped with air hole 101, and after pedestal 100 and cover board 200 are assembled together, air hole 101 is not shielded but in spacious
Open state first by other packed part gluing knots of pedestal 100 and cover board 200 in addition to air hole 101 or is welded on one
It rises, forms sealing, be then again sealed air hole 101, prevent external water, moisture, dust etc. by the air hole 101
Inside access switch, the function of switch is influenced.When air hole 101 seals, three kinds of modes are mainly taken, the first is to pass through dispensing
Mode closes the air hole 101, and second is to be closed the air hole 101 by scalding riveting mode, the third is to pass through indentation
102 mode of steel ball (as shown in Figure 2) closes the air hole 101, requires air hole 101 big using dispensing mode, to mould
The manufacture difficulty of tool requires very high, and there are the hidden danger that glue flows into switch internal, and need to heat the product long period so that
Adhesive curing；It also requires air hole 101 big using boiling hot riveting mode, product is needed locally to bear high temperature；Using indentation steel ball
102 modes require steel ball size sphericity very high, otherwise easily there is gap.The breather hole structure of this switch of the prior art
Extra parts are not only needed, but also when product need not seal, when air hole does not block, the energy such as water, moisture, dust
Inside 101 access switch of air hole, the closure of influencing contactor, even resulting in contact cannot be connected.

Embodiment
It is shown in Figure 3, a kind of breather hole structure of switch of the invention, including pedestal 1 and cover board 2；1 He of the pedestal
The correspondence of cover board 2 is connected and surrounds the cavity 11 for installing switch internal part, and the pedestal 1 is described equipped with leading to from outside
The air hole 12 of cavity 11, the cover board 2 are equipped with to extend to 1 direction of the pedestal and be breathed freely with can cover the air hole 12
Port lid 21, after pedestal 1 is connected with cover board 2, the breather hole cover 21 of the cover board 2 is from outside by the air hole of the pedestal 1
12 cover.
In the present embodiment, the root of the breather hole cover 21 of the cover board 2 is additionally provided with through-hole 211, to increase the air hole
The flexibility of lid during exercise.
In the present embodiment, the breather hole cover 21 of the cover board 2 leans with the air hole 12 of the pedestal 1.Certainly, according to
It needs, can also be the gap for being equipped with preset distance between breather hole cover and the air hole.
In the present embodiment, by super between the hole edge of the breather hole cover 21 of the cover board 2 and the air hole 12 of the pedestal 1
Sound wave welding is mutually fixed.
In the present embodiment, the periphery on the hole edge of the air hole 12 of the pedestal 1 be additionally provided with convenient for ultrasonic welding tool into
What is entered allows bit space 13.In this way, convenient for ultrasonic welding tool is stretched into allow bit space 13 in carry out cover board 2 breather hole cover 21
Ultrasonic bonding between the air hole 12 of pedestal 1.
In the present embodiment, the hole of the air hole 12 of the pedestal 1 is in invaginated type along the outer surface relative to the pedestal 1,
After pedestal 1 is connected with cover board 2, the outer surface of the breather hole cover 21 of the cover board 2 is equal with the outer surface of the pedestal 1
Together.
The present embodiment is that air hole 12 is located on pedestal 1, and breather hole cover 21 is located at cover board 2, it is of course also possible to be
Air hole is set on the cover board, breather hole cover is located on pedestal.
A kind of switch shown in Figure 4, of the invention, including pedestal 1, cover board 2, spring 3, button 4, sealing ring 5, contact
Movable contact spring 6, contact static contact spring piece 7；The spring 3, contact movable contact spring 6 and contact static contact spring piece 7 are attached separately on pedestal 1, described to press
Button 4 is installed on the pedestal 1 by the spring 3 and is connected with the contact movable contact spring 6, by the driving of button 4, realizes
The movable contact of contact movable contact spring 6 is switched on or switched off with the stationary contact of contact static contact spring piece 7；It is additionally provided between pedestal 1 and cover board 2
Breather hole structure as described above.When switch needs sealing, first by other envelopes of pedestal 1 and cover board 2 in addition to air hole 12
Dress part gluing knot welds together, and then the breather hole cover 21 and 12 supersonic welding of air hole are connected together,
