Abstract
A journey contact switch of carbon brush type relates to a travel switch and provides a journey contact switch of carbon brush type, which is provided with an upper cover, a lower cover, a carbon brush conductive cylinder, a pole piece and a fixed plate of the pole piece. The carbon brush conductive cylinder is arranged in an inner cavity of the lower cover; the upper cover and the lower cover are fittingly matched; the pole piece is installed on the fixed plate of the pole piece. The carbon brush conductive cylinder consists of a carbon brush, a spring and a carbon brush conductive terminal; two ends of the spring are connected with the carbon brush and the carbon brush conductive terminal respectively. By utilizing the self lubricating property of carbon brush material, the journey contact switch adopts the carbon brush as a contact, which contacts with the pole piece made of metal to be conductive, thus overcoming the problems of the existing travel switches that the contact is easily worn out and makes big noise, etc. The travel switch also has improved conductivity and mechanical strength. By utilizing elasticity of the spring, the travel switch ensures sufficient contact length of the carbon brush, overcomes the problem that the existing go switch has small contact amount and solves the problem that the journey is susceptible to failure during assembly, transportation and use due to small contact amount. Besides, the journey contact switch of the utility model has simple assembly and low cost, and can be used as a separate component to be used in various products.
Description
Technical field
The utility model relates to a kind of travel switch, especially relates to a kind of employing carbon brush formula contact, is mainly used in the stroke contact-making switch of mechanical sports products of control and equipment.
Background technology
At present, known travel switch has sensitive switch, panel beating formula (metal stamping or cast) switch etc., and all kinds of sensitive switches mainly are made up of switch base, switch cover, Chang Kai and normally closed contact support, inserts, U type reed, switch, moving contact, fixed contact and springboard etc.; And panel beating formula switch is a kind of switch that adopts sheet metal structural, when the bump module of the travel switch on the mechanical moving element [metal stamping (or casting) sheet metal component], the contact action of travel switch, the realization circuit switches, it is according to the travel position of moving component and the electrical equipment of commutation circuit, and its principle is intended mutually with button.Travel switch is widely used in sports products and all kinds of lathe and the hoisting machinery, in order to control its stroke, realizes the effect of terminal position limitation protection.
Summary of the invention
The purpose of this utility model is to provide a kind of carbon brush type stroke tangent switch, with solve ubiquitous life-span of existing sensitive switch short, the contact amount is little, cause problem such as inefficacys in assembling and transportation easily, the ubiquitous contact amount of contact-making switch of metal stamping (or casting) panel beating formula is little, the different sound of contact generation, the problem such as inefficacy that causes such as easy to wear.
The utility model is provided with loam cake, lower cover, carbon brush conductive pole, pole piece and pole piece stator.The carbon brush conductive pole is located at down cover cavity, and loam cake and lower cover cover, and pole piece is installed on the pole piece stator.
The carbon brush conductive pole can be made up of carbon brush, spring and carbon brush conducting terminal, and the two ends of spring are connected with the carbon brush conducting terminal with carbon brush respectively.Preferably establish connecting rod between carbon brush and carbon brush conducting terminal, spring housing is located on the connecting rod.Inboard at loam cake preferably is provided with spring banking stop or spring guide rail, is used for spring spacing of carbon brush conductive pole.Preferably be provided with carbon brush conducting terminal spacer or location notch at the inboard end of lower cover, be used for the location of carbon brush conducting terminal and spring one end; Preferably be provided with carbon brush spacer or location notch at the inboard other end of lower cover, be used for the location of carbon brush.Preferably be provided with stator on pole piece, be provided with fixing hole on stator, the corresponding fixing hole that is provided with on the pole piece stator is used for the fixedlying connected of stator and pole piece stator on the pole piece.Preferably be provided with strengthening wing on pole piece, the corresponding strengthening wing groove that is provided with is used for strengthening wing and is fixed in the strengthening wing groove on the pole piece stator.
Compare with existing travel switch, because the utility model utilizes the self lubricity of carbon brush material will contain the contact head of the carbon brush of a certain proportion of copper powders may as travel switch, contact conduction with the pole piece that adopts metal, overcome problems such as the existing contact head of existing travel switch is easy to wear, friction noise is big.Utilize copper powder to improve electric conductivity, strengthened the mechanical strength of switch.Because the utility model adopts carbon brush and spring assembly design, utilize the elasticity of spring, guarantee that carbon brush has enough contact lengths, therefore overcome the little problem of existing travel switch contact amount, solved because the little problem that in assembling, transportation and use, lost efficacy easily of contact amount.Because the utility model adopts the structural design of carbon brush and pole piece combination, utilize the elasticity of plastic material to adopt the design of buckle-type outer shell construction again, therefore assembling is simple, cost is low, can be used as stand-alone assembly and is applied to various product.
