Description

Ship-shaped switch

Technical Field

The utility model relates to the technical field of switches, in particular to ship type switch.

Background

The boat-type switch is also called a rocker switch, and has the same structure as a toggle switch except that a knob is changed into a boat-type switch, and the boat-type switch is often used as a power switch of electronic equipment. The ship-shaped switch is widely applied to water dispensers, running machines, computer speakers, battery cars, motorcycles, ion televisions, coffee makers, extension sockets, massage machines and the like, and is generally applied to household appliances. Depending on the number of contacts, boat switches can be divided into the following categories: single pole single throw, i.e. one moving contact and one stationary contact; single-pole double-throw, i.e. one moving contact and two stationary contacts (which can be respectively connected with the stationary contacts on both sides); the double-pole single-throw device is characterized in that two channels are arranged, namely two movable contacts and two fixed contacts; double pole double throw, i.e. two moving contacts and four stationary contacts, has four channels (which can be connected to two stationary contacts on both sides, respectively).

The ship type switch of the KCD4 series is one of ship type switches, the rocker and the middle pin of the ship type switch of the series are in linear contact in the early stage, the product performance is poor, the switch is easy to burn when a large current passes through, the service life is short, the structure in the early stage is optimized by the current KCD4 series, but the switch burning phenomenon still occurs.

SUMMERY OF THE UTILITY MODEL

Not enough to the above-mentioned among the prior art, the utility model provides a ship type switch, its is rational in infrastructure, and is longe-lived, and the switch is more nimble, the great electric current of accessible.

In order to achieve the above object, the utility model adopts the following technical scheme: ship type switch, including the switch body, the switch body includes the casing and installs the button in the casing top, the installation is equipped with the wane in the casing, the wane is mutually supported with the button, wane one end downside is equipped with the moving contact, casing below one side grafting installation is equipped with the terminal, the terminal upper end stretches into the casing inside and installs the static contact with moving contact matched with, wane center bottom is equipped with the arc recess, below grafting installation is equipped with well foot in the middle of the casing, well foot top is the arc surface structure to laminate mutually with the arc recess.

As an improvement: the radiuses of the arc-shaped grooves and the arc surfaces on the middle legs are both 0.35 mm.

As an improvement: the button is characterized in that positioning holes are formed in two sides of the shell respectively, positioning columns are arranged on two sides of the button, and the positioning columns can be rotatably installed in the positioning holes.

Compared with the prior art, the utility model the advantage lies in: the arc surface with the radius of 0.35mm is adopted above the middle pin, so that no burrs exist in the product process, the rocker also adopts the arc groove surface with the radius of 0.35mm to be attached to the middle pin, and the larger the first point contact area is, the larger the passing current is, the more the performance of the product is improved; the second point is that the rocker can move more flexibly due to the fact that the product adopts a round-to-round design structure, and rapid contact and rapid disconnection can be improved; and the third point is a circle-to-circle design, so that the product can be in point contact with the movable point at the center of the circle, the service life of the product is prolonged more accurately because the silver layer is thickest at the center of the contact.

reference symbol comparison table:

the device comprises a shell 1, a button 2, a rocker 3, a moving contact 4, a binding post 5, a static contact 6, an arc-shaped groove 7, a middle pin 8, a positioning hole 9 and a positioning column 10.

Detailed Description

The following describes the present invention with reference to the accompanying drawings.

As shown in fig. 1, 2 and 3, ship type switch, including the switch body, the switch body includes casing 1 and the button 2 of installing in casing 1 top, the installation is equipped with wane 3 in casing 1, wane 3 mutually supports with button 2, 3 one end downside of wane is equipped with moving contact 4, the installation of pegging graft in casing 1 below one side is equipped with terminal 5, the terminal 5 upper end is stretched into 1 internally mounted of casing and is equipped with the static contact 6 with moving contact 4 matched with, 3 central bottom of wane is equipped with arc recess 7, the installation of pegging graft below is equipped with well foot 8 in the middle of casing 1, well foot 8 top is the arc surface structure to laminate mutually with arc recess 7.

The radiuses of the arc surfaces on the arc-shaped groove 7 and the middle foot 8 are both 0.35 mm.

The button is characterized in that positioning holes 9 are formed in two sides of the shell 1 respectively, positioning columns 10 are arranged on two sides of the button 2, and the positioning columns 10 are rotatably arranged in the positioning holes 9.

The utility model discloses when concrete implementation, the wane 3 of 4 one ends of moving contact is pushed down the back by button 2, moving contact 4 combines with static contact 6, the circuit switches on, otherwise the circuit disconnection, when button 2 rotates, thereby 7 faces of arc recess of wane 3 and the circular arc surface laminating of well foot 8 top have increased area of contact and have increased the admissible current volume, and enable wane 3 can improve high-speed contact and quick disconnection in the more nimble activity of the centre point of circular arc, in addition because the design of the circle to the circle enables the product and located the point contact of product at the centre of a circle of movable point more accurately lengthened the life of product (because the center department silver layer of contact is thickest).

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and all modifications, equivalents, improvements and the like that are made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
