Description

Simple mini switch

Technical Field

The utility model relates to the technical field of switches, in particular to a simple mini switch.

Background

The words switch are to be interpreted as open and closed. It also refers to an electronic component that can open a circuit, interrupt a current, or cause it to flow to other circuits. The most common switches are electromechanical devices operated by a person, in which there are one or several electrical contacts. The "closed" of a contact means that the electronic contact is conductive, allowing current to flow; an "open" of the switch indicates that the electrical contact is not conductive, creating an open circuit, and not allowing current to flow.

The simplest switch has two pieces of metal called "contacts", which make the current form a loop when they are in contact and open when they are not in contact. The choice of contact metal should be made with regard to its degree of corrosion resistance, since most metals will form insulating oxides after oxidation, which prevents the contact from functioning properly

Preferably, the contact terminal includes a main body fixedly mounted to the insulating housing, and a soldering portion bent and extended from an upper end of the main body and a lower end of the main body.

As a preferred scheme, for the main body portion of each contact terminal, accommodating grooves are formed on two sides of the insertion cavity, and two sides of the main body portion are respectively inserted into the corresponding accommodating grooves from top to bottom for fixation.

As a preferable scheme, bosses are formed on both sides of the main body part, and the bosses are tightly matched with the inner wall of the accommodating groove.

As a preferred scheme, die-cut on the main part and be formed with the barb, the inner wall that should insert the chamber is formed with the draw-in groove, and this barb and draw-in groove cooperation buckle.

As a preferable scheme, the number of the contact terminals is two, the two contact terminals are respectively located at the left side and the right side of the insertion cavity, and the front side and the rear side of the upper surface of the insulating base body are both provided with SMT suction nozzle areas.

Compared with the prior art, the utility model has obvious advantages and beneficial effects, and specifically, the technical scheme includes that:

through being fixed in two contact terminal in the insulating pedestal, only utilize the insertion of insulating thin slice can change the on-state of this switch for two elastic contact portion do not touch each other and connect, switch simple structure, convenient to use.

Detailed Description

Referring to fig. 1 to 5, a specific structure of a preferred embodiment of the present invention is shown, which includes an insulating base 10 and at least two contact terminals 20.

The insulation base 10 has an insertion cavity 101 with an opening facing outward for inserting the insulation sheet 30; in this embodiment, the two sides of the insertion cavity 101 are provided with accommodating grooves 102, the inner wall of the insertion cavity 101 is formed with a locking groove 103, the bottom of the accommodating groove 102 is convexly provided with symmetrical steps 104, and the front and rear sides of the upper surface of the insulating base 10 are both formed with SMT nozzle areas 105; the insulating base 10 is a long body, and the length, width and height thereof are respectively: 4.2mm, 3.4mm, 2.9 mm.

The at least two contact terminals 20 are fixed on the insulating housing 10, each contact terminal 20 has an elastic contact portion 21, and the at least two elastic contact portions 21 are suspended in the insertion cavity 101 and touch-connected to each other. In this embodiment, the contact terminal 20 includes a main body 22 and a soldering portion 23, the main body 22 is fixedly mounted on the insulating housing 10, the elastic contact portion 21 is bent and extended from the upper end of the main body 22, and the soldering portion 23 is bent and extended from the lower end of the main body 22; the two sides of the main body 22 are respectively inserted into the corresponding receiving slots 102 from top to bottom for fixation, and the bottoms of the two sides of the main body 22 are abutted against the upper surfaces of the symmetrical steps 104, so that the contact terminal 20 is accurately combined with the insulating base 10, and the formed mounting structure is firm; bosses 201 are formed on both sides of the main body part 22, and the bosses 201 are tightly matched with the inner wall of the accommodating groove 102; the main body part 22 is punched and formed with a barb 202, the barb 202 is matched and buckled with the clamping groove 103, the barb is arranged for fixing and assembling, and the contact terminal 20 cannot withdraw from the insulating base 10 permanently; specifically, the contact terminals 20 are two, which are respectively located on the left and right sides of the insertion cavity 101.
