Insulating body 10, substantially in the rectangular-shaped of upper opening, including bottom wall 100 and from the surrounding of bottom wall 100 vertically upward
The first side wall 102 and second sidewall 104 of extension, the side wall 102,104 of above-mentioned bottom wall 100 and first, second are collectively forming one
Receiving space 106, movable terminal 30 and actuator 40 are contained in the receiving space 106, wherein the bottom wall 100 of insulating body 10
Some recesses 1000 are provided with, the shape of these recesses 1000 is consistent with the shape of fixing terminal 20, additionally, insulating body 10
First, the inner surface of second sidewall 102,104 be in arc-shaped, coordinate with movable terminal 30 and actuator 40, and each second
Plane where the outer surface two ends of side wall 104 caves inward to form a pair of buckling parts 1040 compared to the plane in center, in the button
Be respectively equipped with conjunction portion 1040 blocked block 1042 with the buckle of lid 50, in addition, on the buckling parts 1040 and positioned at above-mentioned card
That holds block 1042 is arranged right below a trapeze cut 1044 upwardly extended from bottom wall 100, with the corresponding structure of lid 50
Coordinate.In fact, the shape of above-mentioned breach 1044 can also be rectangle, square, trapezoidal simply one kind therein.
Movable terminal 30, it is substantially in the form of annular discs, it is placed in the receiving space 106 of insulating body 10, and positioned at fixing terminal 20
Top, and with the second fixing terminal 202 or disconnect or contact, so as to reach circuit switching.It is in dome shape, center part compared with
Edge raises up, also, the contact site 204 of the second fixing terminal 202 is low compared with the contact site 204 of the first fixing terminal 200, because
This, is placed in insulating body 10 and during in normality when movable terminal 30, and movable terminal 30 only has marginal portion and the first fixing end
The contact site 204 of son 200 is contacted, and remains contact, and the part that its center raises up is only in the presence of external force
Can just be contacted with the contact site 204 of the second fixing terminal 202, so, also ensure that the normal switching between circuit.
Actuator 40, two hollow cylinders not waited by cross-sectional sizes are constituted, and the less cylinder in its middle section is press section
400, the larger cylinder in section is Actuator Division 402, and press section 400 is located at the top of Actuator Division 402, when external force is applied to actuator
When 40, Actuator Division 402 acts on movable terminal 30, so as to reach the switching of circuit.
Lid 50, is made up of metal material via punching press or other processing methods, is overlying on the top of insulating body 10, including
Tabular roof 500 and a pair of the welding foots 502 extended separately down from the relative both sides of roof 500, the wherein center of roof 500
Perforate 5000 is offered so that the press section 400 of actuator 40 passes through, and each middle position of welding foot 502 offer it is logical
It is additionally provided with hangnail 506 on the inside of hole 504, and the through hole 504 to coordinate with the interference clamping of insulating body 10, in addition, lid 50 is welded
The second sidewall 104 that pin 502 is close to insulating body 10 extends, and it is more long than the second sidewall 104 of insulating body 10, therefore, when
After lid 50 is overlying on insulating body 10, its welding foot 502 slightly exposes the bottom wall 100 of insulating body 10 and is connected with circuit board.
During assembling, fixing terminal 20 is molded in insulating body 10 first, wherein the contact site 204 of fixing terminal 20 shows
The bottom wall 100 of insulating body 10 is exposed to, and weld part 206 is then exposed to outside insulating body 10 and be connected with circuit board, then may be used
Moved end 30, actuator 40, and lid 50 are sequentially placed into insulating body 10, wherein perforate of the actuator 40 from lid 50
5000 pass in order to apply active force in the Push switch 1, and lid 50 is by the through hole 504 on welding foot 502 and insulation
The interference of corresponding blocked block 1042 is clasped and connects on body 10, and welding foot 502 is slightly exposed to the bottom wall of insulating body 10
100.Finally, the welding foot 502 of the bottom wall 100 of insulating body 10 and the weld part 206 of fixing terminal 20 are exposed by lid 50 and
The Push switch 1 is connected with circuit board.
When Push switch of the present invention 1 is connected with circuit board, because circuit board scribbles tin cream in itself, and the lid of Push switch 1
50 welding foot 502 is coated with tin layers in madial wall, therefore, when the Push switch 1 is placed on circuit board, and entered furnaceman's sequence
When, the tin cream on circuit board will climb along the welding foot 502 of lid 50, so as to reach the connection with circuit board, therefore,
Whether what Push switch 1 was connected with circuit board consolidates, and the tin cream being just decided by circuit board climbs up the degree of lid 50, that is,
Say, tin cream climbs higher along lid 50, Push switch 1 is also more firm with the connection of circuit board, and traditional Push switch,
Due to lid 50 welding foot 502 tightly be attached to the second sidewall 104 of insulating body 10, therefore, the tin cream on circuit board can only
It is climb along the outer wall of welding foot 502, so, Push switch 1 would not be very firm with the connection of circuit board, and this embodiment party
Formula to be used and open up a breach 1044 in the second sidewall 104 contacted with the welding foot 502 of lid 50 on insulating body 10, and
The breach 1044 extends to the bottom wall 100 of insulating body 10, therefore, when furnaceman's sequence was carried out, tin cream on circuit board not only edge
The outer wall of lid 50 to climb, the inwall of welding foot 502 that can also be along the breach 1044 of insulating body 10 in lid 50 is climb, this
Sample, has been considerably improved the active force that Push switch 1 firmly grasps circuit board, so that Push switch 1 can more securely be connected to electricity
On the plate of road.
The present invention is not limited to above-mentioned specific embodiment, one of ordinary skill in the art from above-mentioned design,
Without performing creative labour, done a variety of conversion are within the scope of the present invention.
