The first side wall 102 and second sidewall 104 of extension, the above-mentioned side wall 102,104 of 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
Provided with some recesses 1000, the shape of these recesses 1000 is consistent with the shape of fixing terminal 20, in addition, insulating body 10
First, the inner surface of second sidewall 102,104 be in arc-shaped, to 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, it is square, it is 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 that reach circuit switching.It is in dome shape, central 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, when movable terminal 30 is placed in insulating body 10 and during in normality, 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
It 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 to pass through for the press section 400 of actuator 40, and each middle position of welding foot 502 offer it is logical
Hole 504, and the inner side of through hole 504 is additionally provided with hangnail 506 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 longer 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 to be 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 to 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 switch module 1, and lid 50 passes through the through hole 504 on welding foot 502 and insulation
The interference of corresponding blocked block 1042 is clasped and connected 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 exposed by lid 50 and
The switch module 1 is connected with circuit board.
When the utility model switch module 1 is connected with circuit board, because circuit board scribbles tin cream in itself, and switch module 1
The welding foot 502 of lid 50 is coated with tin layers in madial wall, therefore, when the switch module 1 is placed on circuit board, and enters furnaceman
During sequence, the tin cream on circuit board will climb along the welding foot 502 of lid 50, so that reach the connection with circuit board, because
This, whether what switch module 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, tin cream climbs higher along lid 50, and the connection of switch module 1 and circuit board is also more firm, and traditional switch
Component, 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
It can only be climb along the outer wall of welding foot 502, so, switch module 1 would not be very firm with the connection of circuit board, and this reality
Apply mode and use and open up a breach in the second sidewall 104 that is contacted on insulating body 10 with the welding foot 502 of lid 50
1044, and the breach 1044 extends to the bottom wall 100 of insulating body 10, therefore, when carrying out furnaceman's sequence, the tin cream on circuit board
Climb not only along the outer wall of lid 50, can also along insulating body 10 breach 1044 lid 50 the inwall of welding foot 502 to
Swash, so, the active force that switch module 1 firmly grasps circuit board has been considerably improved, so that switch module 1 can more securely connect
It is connected on circuit board.
The utility model is not limited to above-mentioned specific embodiment, and one of ordinary skill in the art visualizes from above-mentioned
Hair, without performing creative labour, made a variety of conversion are all fallen within protection domain of the present utility model.
