Description

A kind of microswitch

Technical field

The utility model relates to a kind of switches, more specifically, it relates to a kind of microswitch.

Background technique

Microswitch is that have small contact separation and snap-action mechanism, therefore named because the contact spacing of its switch is smaller Microswitch is called sensitive switch, and since its internal structure is very complicated, once leading to internal damage, what can be repaired is several Rate compares small.

Utility model content

In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of microswitches.

To achieve the above object, the utility model provides following technical solution: a kind of microswitch, including shell and shell Lid, one end of the shell are equipped with normally opened terminal and normally closed terminal in gap setting, the normally opened terminal and normally closed terminal One end is equipped with electric contact block, and the other end of the shell is equipped with operation and turns round, and shell, the other end are extended in one end that the operation is turned round Equipped with motion bar, it is equipped with spring between the motion bar and housing sidewall, is hinged with rotatable lamella, the rotation on the motion bar One end of piece extends between normally opened terminal and normally closed terminal, and the end of the rotatable lamella is additionally provided with work corresponding with electric contact block Movable contact, the rotatable lamella middle part are also equipped with the round bar being rotatably assorted, and one end of the round bar is fixed on shell, the shell It is additionally provided with common terminal in vivo, one end of the common terminal is connect with rotatable lamella.

The utility model is further arranged to: the armature contact includes the movable sleeve for being set in rotatable lamella end, described Be equipped with shaft in movable sleeve, the shaft is fed through rotatable lamella, the movable sleeve relative to normally opened terminal and normally closed terminal two Side is equipped with dynamic contact block.

The utility model is further arranged to: one end of the common terminal connects rotatable lamella by copper wire.

By using above-mentioned technical proposal, when people use microswitch, can be carried out by pressing operation torsion fast The operation of speed, internal structure is very simple, but can guarantee the whole stability of switch again, convenient for daily maintenance, very It is practical, it is set as rotatable movable sleeve by that will move contacts, movable sleeve is equipped with corresponding with normally opened terminal and normally closed terminal Dynamic contact block can so that rotatable lamella can be contacted more smoothly when being in contact with normally opened terminal or normally closed terminal More stable, the anti-stop contact block poor contact of energy is very practical, by setting the connection between common terminal and rotatable lamella It is set to copper wire connection, so that rotatable lamella can both play the connection of circuit in the course of rotation, it will not be dry by what is connected It disturbs, causes rotatable lamella that can not normally realize rotation, it is very practical.

Specific embodiment

The utility model embodiment is described further referring to figs. 1 to Fig. 3.

The utility model discloses a kind of microswitch, including shell 1 and cap 2, one end of the shell 1 is equipped between being in One end of the normally opened terminal 10 and normally closed terminal 11 of gap setting, the normally opened terminal 10 and normally closed terminal 11 is equipped with electric contact block 3, The other end of the shell 1 is equipped with operation and turns round 4, and shell 1 is extended in one end that the operation turns round 4, and the other end is equipped with motion bar 40, It is equipped with spring 41 between 1 side wall of the motion bar 40 and shell, is hinged with rotatable lamella 5, the rotatable lamella 5 on the motion bar 40 One end extend between normally opened terminal 10 and normally closed terminal 11, the end of the rotatable lamella 5 is additionally provided with corresponding with electric contact block 3 Armature contact 6,5 middle part of the rotatable lamella is also equipped with the round bar 50 being rotatably assorted, and one end of the round bar 50 is fixed on shell On body 1, common terminal 12 is additionally provided in the shell 1, one end of the common terminal 12 is connect with rotatable lamella 5.The activity Contact 6 includes the movable sleeve 60 for being set in 5 end of rotatable lamella, is equipped with shaft 61 in the movable sleeve 60, the shaft 61 is worn Rotatable lamella 5 is crossed, the movable sleeve 60 is equipped with dynamic contact block 62 relative to the two sides of normally opened terminal 10 and normally closed terminal 11.It is described total One end of go side 12 connects rotatable lamella 5 by copper wire 120.

In actual operation, when people use microswitch, 4 can be turned round by pressing operation, 4 one end are turned round in operation at this time Motion bar 40 can stress, spring 41 will do it contraction, at the same rotatable lamella 5 hinged on motion bar 40 also can stress turned It is dynamic, due to being equipped with the round bar 50 being rotatably assorted in the middle part of rotatable lamella 5, so extending to normally open end when the rotation of one end of rotatable lamella 5 The other end between son 10 and normally closed terminal 11 is also corresponding to be swung, and the armature contact 6 that is at this moment arranged on rotatable lamella 5 can be separate Normally closed terminal 11 is in contact with normally opened terminal 10, and microswitch is in opened condition at this time.When people turn round 4 force knot to operation Shu Shi, the restoring force that motion bar 40 will receive spring 41 itself are restored to original position, the work of 5 one end of rotatable lamella setting at this time Movable contact 6 can be in contact, microswitch is in closed state at this time, whole use far from normally opened terminal 10 with normally closed terminal 11 Very convenient, internal structure is simple, convenient for the maintenance of people and the replacement of components.It is set as to turn by the way that 6 will be moved contacts Dynamic movable sleeve 60, movable sleeve 60 are equipped with dynamic contact block 62 corresponding with normally opened terminal 10 and normally closed terminal 11, so that rotation Piece 5 can be contacted more smoothly when being in contact with normally opened terminal 10 or normally closed terminal 11, can be more stable, Anti- 62 poor contact of stop contact block of energy, it is very practical.By setting copper for the connection between common terminal 12 and rotatable lamella 5 Line 120 connects so that rotatable lamella 5 can both play the connection of circuit in the course of rotation, will not by the interference connected, Cause rotatable lamella 5 that can not normally realize rotation, it is very practical.This practical microswitch structure simple and stable is damaging When can be easy to repair.

The above is only the preferred embodiment of the utility model, and the protection scope of the utility model is not limited merely to Above-described embodiment, technical solution belonging to the idea of the present invention belong to the protection scope of the utility model.It should refer to Out, for those skilled in the art, it is without departing from the principle of the utility model it is several improvement and Retouching, these improvements and modifications also should be regarded as the protection scope of the utility model.
