Problems solved by technology

[0003] However, the existing switch has the problem of large frictional interference. Since the switching action of the switching switch of the electronic device is frequent, the shrapnel and electrodes may be worn due to frictional interference under long-term use, so that the switching action cannot be completed reliably. , in addition, the toggle switch after wear and tear can not provide the user with a better operating feel

Embodiment Construction

[0041] see figure 1 and Figure 10 As shown, it is a pull-type rotary cut filter device of the present invention, which includes: a rotary cut device 1 , a transmission line 2 and a filter 3 .

[0042] see figure 1 As shown, the rotary cutting device 1 is a tubular structure, which includes a housing 11 and a pull knob 14 arranged at one end of the housing 11, the filter 3 is arranged in the housing 11 (such as Figure 6A shown), the transmission line 2 runs through both ends of the rotary cutting device 1 and is electrically connected to the filter 3. The transmission line 2 can be electrically connected to a power supply (not shown) and transmits appropriate signals through the filter 3 to electronic device.

[0043] see figure 2 As shown, the user can pull the pull-out knob 14 of the rotary cutting device 1 , rotate it and then push it back. In this way, the electrical state can be switched through this action.

[0044] see image 3 As shown, the rotary cutting devic...

Abstract

The invention relates to a drawing type rotary-cutting filtering device comprising a rotary-cutting device, a transmission line and a filter, wherein the rotary-cutting device comprises a shell, a firm joint seat, a base plate, a drawing knob and a contact terminal; the shell is provided with an opening and a through hole; the firm joint seat is provided with a run-through hole, a first eccentricpunch hole and a second eccentric punch hole; the base plate is provided with an electric contact and a plate hole; the drawing knob is provided with a central shaft lever, an eccentric inserted linkand a contact terminal; the central shaft lever is provided with a through shaft hole and penetrates through the run-through hole and the plate hole; the eccentric inserted link is inserted in the first eccentric punch hole; the contact terminal is arranged at the tail end of the eccentric inserted link and is abutted with the electric contact of the base plate; the transmission line penetrates through the shaft hole, the run-through hole, the plate hole and the through hole and is electrically connected with the electric contact; and the filter and the transmission line are electrically connected. Thus, the interruption of the original electric state, caused by false contact, can be effectively avoided, and the unnecessary friction interference generated by the contact terminal can be avoided.

Description

technical field [0001] The invention relates to a pull-type rotary-cut filter device, in particular to a pull-type rotary-cut filter device capable of switching between two electrical states. Background technique [0002] The electrical state switching of electronic devices usually relies on the operation of switches, and the most common one is the two-stage switching path / open circuit state switch. This type of switch is usually push-type or push-type, and the push-type switch is the most common. It is usually equipped with a shrapnel and switches the open circuit and the open state with elastic force, while the push-type switch bridges the two electrodes through a sliding action to create an electrical connection. [0003] However, the existing switch has the problem of large frictional interference. Since the switching action of the switching switch of the electronic device is frequent, the shrapnel and electrodes may be worn due to frictional interference under long-term...
