Description

One kind patching microswitch

Technical field

The utility model relates to switching technique field, in particular to one kind patches microswitch.

Background technique

Microswitch is that have small contact separation and snap-action mechanism, and it is dynamic to carry out switch with defined stroke and defined power The contact mechanism of work, is covered with shell, outside have a kind of switch of drive rod because contact spacing of its switch is smaller, Therefore named microswitch, is called sensitive switch.

Usually microswitch is fixed with screw, and to microswitch welding lead extraction or more inserting modes Outer lead is connected, connection is inconvenient, and wiring is error-prone, and for the microswitch being installed on circuit board, installation fixes ten Divide inconvenience.

Utility model content

For the technical problem more than solving, the utility model provides one kind and is intended to be easily installed fixed, wiring process letter Change, easily fabricated, at low cost patch microswitch.

The utility model is achieved through the following technical solutions:

The utility model discloses one kind to patch microswitch, including Switch main body and socket, the top of the Switch main body End is equipped with button, and bottom end is equipped with pin；The pin is corresponding to be plugged into perforation set on jack in the socket, and the jack is set There is connecting terminal, the connecting terminal is electrically connected with the pin.

Further, the socket both ends are respectively provided with hook, the hook and the hook slot for being set to the Switch main body both ends It snaps connection.

Further, the pin includes the common pin set gradually, normally opened pin and normally closed pin, when the button When by downward external force, the common pin realizes that circuit is connected with normally opened pin；When the button is not affected by outside downwards The masterpiece used time, the common pin realizes circuit disconnection with normally opened pin and common pin is connected with normally closed pin restoring circuit.

The one kind for implementing the utility model patches microswitch, has following technical characteristic and beneficial technical effect:

The utility model patches microswitch using microswitch and socket one inserting mode, no-welding line, together When substantially increase assembly efficiency, reduce production cost.

Detailed description of the invention

In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to implementation Example or attached drawing needed to be used in the description of the prior art are briefly described, it should be apparent that, the accompanying drawings in the following description is only It is only some embodiments of the utility model, for those of ordinary skill in the art, in not making the creative labor property Under the premise of, it is also possible to obtain other drawings based on these drawings.

Fig. 1 is the decomposition texture schematic diagram for patching microswitch of the utility model embodiment；

Fig. 2 patches Switch main body structural schematic diagram in microswitch for the utility model embodiment；

Fig. 3 is the external structure schematic diagram that the utility model embodiment patches microswitch.

Wherein, 1- Switch main body, 2- socket, 11- button, 12- pin, 13- hook slot, 121- common pin, 122- are normally opened The normally closed pin of pin, 123-, 21- jack, 22- connecting terminal, 23- hook.

Specific embodiment

The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts Every other embodiment obtained, fall within the protection scope of the utility model.

Patch microswitch and patch microswitch and generally use spring leaf as power secondary drive module, by spring leaf with Fixed contact occurs Rapid contact and completes on or off operation；Due to needing spring leaf preferably to spring back effect and longer use Service life, the materials such as beryllium-bronze, tin bronze, stainless steel that generally use that elasticity is good special are fabricated to spring leaf.

Fig. 1, Fig. 2 and Fig. 3, the preferred embodiment of the utility model are please referred to, one kind patching microswitch, including switch Ontology 1 and socket 2, the top of Switch main body 1 are equipped with button 11, and bottom end is equipped with pin 12；The correspondence of pin 12 is plugged into perforation The jack 21 in socket 2, jack 21 are equipped with connecting terminal 22, and connecting terminal 22 is electrically connected with the pin 12.

Preferably, 2 both ends of socket are respectively provided with hook 23, hook 23 is buckled with the hook slot 13 for being set to 1 both ends of Switch main body to be connected It connects.

Pin 12 includes the common pin 121, normally opened pin 122 and the normally closed pin 123 that set gradually, when button 11 by When downward external force, common pin 121 realizes that circuit is connected with normally opened pin 122；When button 11 is not affected by downward outer masterpiece Used time, common pin 121 realizes circuit disconnection with normally opened pin 122 and common pin 121 is led with normally closed 123 restoring circuit of pin It is logical.

It is further described below:

One kind provided by the utility model patches microswitch, and wherein Switch main body includes button, upper cover, lever, elasticity Part, normally closed terminal, normally closed terminal stationary contact, normally opened terminal, normally opened terminal stationary contact, public terminal, movable contact, movable plate and base Seat.Pedestal with normally opened terminal, normally closed terminal, public terminal is fixed together using encapsulated technique, base top setting Fixing groove；Button is put into the button slot of upper cover from upper cover bottom, and button head stretches out upper cover, and button bottom and lever one terminate Touching, the lever other end are connected with public terminal, and lever is equipped with rectangular first through hole close to one end of button, elastic component Driving portion is inserted into rectangular first through hole and is connected, and a rectangle third is logical on the operating member and movable plate of the elastic component other end Hole is connected, and movable plate one end tool bifurcated port is stuck in the strip groove of public terminal upper end, thus connect with public terminal, Not under conditions of by external force, the movable contact on movable plate contacts the normally closed terminal stationary contact on normally closed terminal, forms common end The sub access connected with normally closed terminal.After button is driven external force, the driving portion of lever is pushed to move downward, elastic component is downward It moves and stress generates deformation, upward impetus power is generated in movable plate, pushes the normally closed stationary contact of movable plate and normally closed terminal It disconnects, movable plate and normally opened termination contact is switched to, when button is not by external force, in the reply that elastic component is generated by compression Power can be such that the normally opened terminal stationary contact of movable plate and normally opened terminal disconnects, and movable plate replys the normally closed stationary contact point contact with normally closed terminal State realize the conversion function of switch two-way NO-OFF-ON to realize the switching between two-way circuit.

Specific embodiment described herein is only to give an example to the utility model aims.The utility model Person of ordinary skill in the field can make various modifications or additions to the described embodiments or using class As mode substitute, but objective without departing from the utility model or beyond the scope of the appended claims.
