CN2689429Y - Electronic limiting microswitches - Google Patents

Abstract

The utility model discloses an electronic limiting microswitch, comprising a fixing guide post, a button, wire connecting terminals, a cover and a spring. The spring is embedded in a center concave hole of the fixing guide post, and then the button is matched in. A center hole of the cover is aimed at the button and is penetrated and covers the lower end of the button, and the lower end of the fixing guide post is inserted with the wire connecting terminals. The utility model uses the advantage of the spring that has wide telescopic space and long service life, so continuous pushing button does not lead to misplacement, even more machine stopping. In this way, the production quality of the microswitch is improved greatly, and the utility model has the advantages of obvious economic benefit, simple structure and convenient operation.

Description

The electronic limit sensitive switch

Technical field

The utility model relates to a kind of electronic limit sensitive switch, particularly a kind of electronic limit sensitive switch that utilizes spring.

Technical background

At present, known electronic limit sensitive switch core texture all is the electronic limit sensitive switch that utilizes reed to make, utilize the disadvantage of the electronic limit sensitive switch of reed structure to be to use short, easily dislocation of life-span, can cause the consequence of deadlock when serious, and manufacturing process more complicated cost is higher.

In order to overcome existing electronic limit sensitive switch, short, easy dislocation in useful life, the technical deficiency that easily crashes, the utility model provides a kind of electronic limit sensitive switch, this electronic limit sensitive switch core texture is to utilize the spring structure manufacturing to form, utilize the maximum characteristics of electronic limit sensitive switch of spring manufacturing to be to use long, difficult dislocation of life-span, the fairly simple cost of the more not phenomenon that can occur crashing, and manufacturing process is low.

The technical scheme that its technical problem that solves the utility model adopts is: repack electronic limit sensitive switch core texture reed into spring, fixedly embedding spring earlier in the concave hole of guide pillar center, after allocate button into, the central aperture button of lid passes and covers the button lower end, fixedly the guide pillar lower end is allocated binding post into, utilizes spring hypertonic space big like this, the advantage of long service life, improved the product quality of electronic limit sensitive switch greatly, economic benefit is obvious.

The beneficial effects of the utility model are the phenomenons that also can not misplace, more can not occur crashing when the continuous button of electronic limit sensitive switch, long service life, and also simple in structure.

Description of drawings:

Below in conjunction with accompanying drawing and example the utility model is further specified:

Fig. 1 is a structure chart of the present utility model

Fig. 2 is a side view of the present utility model

Fig. 3 is a vertical view of the present utility model

Fixing guide pillar in the drawings, 1; 2, button; 3, binding post; 4, lid; 5, spring.

Specific embodiment:

In Fig. 1, button (2) contacts with spring (5), and spring (5) contacts with binding post (3), and pressing button during use (2) contact spring (5) contacts binding post (3) control power supply again by spring (5) and carries out switching manipulation.

Claims (2)

1, a kind of electronic limit sensitive switch, in fixing guide pillar center concave hole, embed spring earlier, after allocate button into, the central aperture button of lid passes and covers the button lower end, fixedly the guide pillar lower end is allocated binding post into, it is characterized in that fixedly embedding in the concave hole of guide pillar center spring and matches with button.

2, according to the described electronic limit sensitive switch of claim 1, its feature is that also spring and binding post contact.
