Abstract
The invention discloses a novel band switch potentionmeter which mainly introduces a tongue tube to replace the traditional mechanical contact and comprises a fixed shell, an insulating plate, a rotary or push handle and a locating mechanism. The insulating plate, the locating mechanism and the inside of the handle are installed in the shell, the handle is movably installed on the shell, the outside of the handle is used for rotary or liner sliding operation, the inside of the handle and the locating mechanism rotate or slide in a matching way, and a magnet is also installed near the insulating plate. A plurality of reed pipes and a plurality of resistors are installed on the insulating plate, the resistors are sequentially connected in series, terminals are educed from each resistor from heads and ends of resistors, one end of each reed pipe is connected with a serial point of each resistance according to the needs, and the other ends of the plurality of reed pipes are connected together and educe terminals. The band switch potentionmeter has the advantages that a contact is sealed in protective gas, an operation part is completely isolated with a circuit, and the invention can be suitable for various hostile environments and is widely applied to various fields, in particular to each high end field.
Description
Technical field
The present invention relates to various electronic products used a kind of band switch and potentiometer, particularly a kind of novel Wave-band switch potentiometer.
Background technology
The potentiometer of prior art is divided into membrane type potentiometer and Wound-rotor type potentiometer by resistance type.The membrane type potentiometer mainly is on the resistance that covers one deck carbon film or synthetic film and so on the insulator, and in addition slide to realize the adjusting of resistance in the contact; The Wound-rotor type potentiometer is on one section resistance wire, to add a contact to slide to realize the adjusting of resistance.Right eventually because of the loose contact of contact and its performance of effect of attrition and the life-span of resistance.Common high-quality Wave-band switch potentiometer starts the life-span also with regard to about 10,000 times, and for satisfying high-performance and prolong its useful life, noble metal such as gold-plated on its contact, alloy of some manufacturer's regardless of expense satisfies its performance requirement as far as possible.For satisfying its performance demands; After developed electronic potentiometer again, comprise the magnetosensitive class, the photoelectricity class, numeric class etc., though this electron-like potentiometer does not contact the contact; Optimized performance; Yet, influenced its application because leakage current and electronic noise have appearred in electronic circuit inevitably.In the occasion of some high performance requirements, like high end audio equipment etc., the gold-plated Wave-band switch potentiometer that waits of the use that people still spare no high price satisfies its performance.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, cost is low, performance is remarkable Wave-band switch potentiometer; Make the far ultra existing product of its serviceability; Be more than tens times and even hundred times of existing product its useful life, and can adapt to various abominable environments for use.
For realizing above-mentioned purpose, technical solution of the present invention is:
The present invention is a kind of novel band switch and potentiometer, and it has mainly been introduced tongue tube and has replaced mechanical contact in the past in Wave-band switch potentiometer, by fixed housing, insulating circuit board, revolve or pushing handle, detent mechanism are formed.Described insulating circuit board, detent mechanism and handle inside are installed in the shell, and handle is movably installed on the shell, and handle divides the inside and outside; Outside in housing exterior; Be used for rotation or linear slide operation, inner in enclosure and detent mechanism movingly, rotatable location or linear slide are located; It is equipped with magnet near place, insulating circuit board end; If be used for make-before-break, then just corresponding two tongue tube positions are if be used for the then just corresponding tongue tube position of break-before-make by demand for the size of magnet.Some resistance and some tongue tubes are installed on the insulating circuit board, and resistance is connected successively, and head and the tail are drawn terminals, are connected in the resistance series connection point by demand tongue tube one end, and the other end connects together and draws terminals, and tongue tube is arranged side by side.
Some resistance and some tongue tubes are installed on insulating circuit board, when resistance is got suitable limited resistance, promptly can be used as potentiometer and use; When resistance is got infinitely large quantity, promptly can be used as band switch and use.
Because the present invention has introduced tongue tube and replaces mechanical contact in the past in Wave-band switch potentiometer,, and make the advantage that this Wave-band switch potentiometer tool is given prominence to because of the performance of the excellence of tongue tube itself; Can reach more than 1,000,000 times its useful life, is more than hundred times of existing product, and owing to its contact is sealed in the protective gas; Its functional unit is complete and circuit is isolated; Can adapt to various rugged environments, be widely used in every field, particularly each high-end field.
