Description

A rotary dip switch < RTI ID = 0.0 >

The present invention relates to a dip switch constituting an electronic circuit, and more particularly to a rotary type dip switch.

As electronic components have become smaller, rotary dipswitches have also been developed to be very small in size, while forming many contact combinations.

In general, a rotary switch is used to select one of a plurality of options, and is for selecting a desired contact by rotating the wiper to a circumferentially arranged contact rather than a simple button.

That is, the microcomputer detects and controls the number of pulses that change according to the total amount of left and right rotations by taking advantage of the characteristics of a rotary encoder that converts the amount of mechanical analog change to digital, and is configured to perform specific functions. Devices, solar energy devices, lighting control devices, and the like.

In addition, the body may be made of a plastic material, and the click projection may be made of stainless steel.

Further, the rotor may be formed by injection-molding the body in a state where the click projection is arranged in advance in the metal mold.

According to the rotary dip switch according to the embodiment of the present invention,

First, since the detachable knob allows the knob to be combined and adjusted only when necessary, the switch can be controlled only by the post-manager, thereby improving the security.

Second, when only the click protrusion included in the rotor is provided with a metal material, the click protrusion can be prevented from melting due to heat generated when the rotary dip switch is mounted on the board.

Third, because of the curved portion of the terminal terminal, it is possible to prevent the terminal terminal from being cut when the cover and the terminal base are combined using the ultrasonic welding, thereby reducing the defect rate at the time of manufacturing.

Fourth, since the contact of the terminal terminal does not touch the upper surface of the terminal base, the malfunction can be prevented by the groove formed on the upper surface of the terminal base.

Fifth, the terminal base is provided with a plurality of spaced-apart projections, so that the defect rate of the rotary dip switch can be reduced.

Referring to Figs. 1 to 4, a rotary dip switch RS includes a terminal base 100, a printed circuit board 200, a rotor 300, a knob 400, and a cover 500.

The terminal base 100 has a plurality of terminal terminals 110 on which respective contacts 111 are arranged on one axis.

Here, the terminal terminal 110 may be formed such that one side portion extending in the longitudinal direction is gradually curved to a predetermined width while forming a smooth curve to the inside of the terminal terminal 110, or both sides extending in the longitudinal direction may be formed to be straight .

The terminal base 100 has a groove 130 for separating the contact 111 from the upper surface of the terminal base 100 below the terminal terminal 110 disposed on the upper surface.

When the contact point 111 touches the upper surface of the terminal base 100, it does not return to its original position, and malfunction of the rotary dip switch RS may occur.

7, the contact 111 and the upper surface of the terminal base 100 are separated from each other due to the groove 130 formed on the upper surface of the terminal base 100, It is possible to prevent malfunction of the rotary dip switch RS.

The terminal base 100 further includes a plurality of spaced apart protrusions 120 for sensing a failure at a side of one end of the terminal terminal 110 and at a side of the end contact point 111 of the terminal terminal 110.

The plurality of spacing protrusions 120 serve to guide the terminal terminal 110 to the correct position when the terminal terminal 110 is inserted into the terminal base 100 and bent. Therefore, if the terminal terminal 110 is not correctly bent, the terminal terminal 110 is placed on the spacing protrusion 120, thereby detecting the failure of the terminal base 100, and the failure rate of the rotary dip switch RS .

The plurality of spacing protrusions 120 are disposed at intervals corresponding to the width of the terminal terminal 110 so that the terminal terminal 110 can be prevented from being twisted when the terminal terminal 110 is positioned at the correct position. Furthermore, the number of the spacing protrusions 120 can be reduced by the groove 120 formed in the terminal base 100, compared with the conventional one.

6 (a), the conventional terminal terminal 140 is connected to the terminal base 100 and the cover 500 by means of ultrasonic welding, The angled portion 141 can be cut like the cutting line L when the ultrasonic welding is performed. However, the terminal terminal 110 of the present invention shown in Fig. 6 (b) is not cut by the curved portion 112 at the time of ultrasonic welding. Therefore, it is possible to reduce the defective ratio of the rotary dip switch RS to the normal manufacturing process. The terminal terminal 110 may be an elongated rectangular shape without the curved portion 112 as shown in Fig. 6 (c).

The printed circuit board 200 is disposed on the upper portion of the terminal base 100, and a conductor pattern is formed.

The rotor 300 is coupled to the upper portion of the printed circuit board 200 and rotates the printed circuit board 200.

Further, the body 310 may be made of plastic, and the click protrusion 320 may be made of a metal material or stainless steel material.

The click protrusion 320 is prevented from melting due to the heat generated when the rotary dip switch RS is mounted on the board due to the metal click protrusion 320.

Referring to FIG. 5, the rotor 300 is formed by first arranging the click protrusion 320 in the mold frame, and then by injection molding the body 310. Therefore, as shown in FIG. 5, the click protrusion 320 passes through the body 310 and is buried. Here, the injection molding for forming the body 310 may be insert injection molding.

 The knob 400 is detachably coupled to the rotor 300 and coupled to the upper portion of the body 310 of the rotor 300 to rotate the rotor 300.

Since the detachable knob 400 can adjust the knob 400 only when necessary, it can be adjusted only by an administrator in post-management, thereby improving security.

The cover 500 is coupled to the terminal base 100 at an upper portion of the terminal base 100 and has a plurality of fixing grooves 510 for fixing the click projections 320 therein. 200 and a rotor 300.

A hole 520 is formed in the upper part of the cover 500 so that the knob 400 can be coupled to the rotor 300.

According to the rotary dip switch RS according to the embodiment of the present invention, the knob 400 can be coupled to the rotor 300 only when needed by the detachable knob 400 and the rotary dip switch RS can be controlled After the installed knob 400 is installed only by the manager, it can be controlled only by the manager, which can improve the security of the control of the air conditioning system and the automation equipment.
