Technical field
The utility model relates to a kind of dust collector expansion pipe with scalable wire connection device.
Background technology
In the telescoping tube of dust catcher, be provided with and be used for electric current is introduced into lead in the scrubbing brush from external power supply, because telescoping tube is scalable, so this lead also must be arranged to can be with the telescopic adjustment length of expansion link, therefore generally this lead segmentation is provided with, wherein one section for the electric body that is subjected to of fixedlying connected of being electrically connected of the electrical work parts of dust catcher, another section is the conductor that is fixedly connected with power supply, and this conductor can be flexible wire or rigid wire bar.
In the prior art, contacted by a face by electric body and electrical connection between the rigid wire bar realizes.Being subjected to electric body is the flat copper sheet that is fixed in the expansion link, and contact is put mutually with the outer surface of cylindrical conductor bar in the surface of one side.Because contact point has only a bit, therefore the reliability of conduction is not high.If adopt flexible wire, then it is changeless reliable the contact with being subjected to electrically contacting between the electric body, but the winding of lead and flexible all inconvenient influences it and slides with the relative slip between the telescoping tube inner and outer pipes.
The utility model content
The purpose of this utility model is to provide a kind of dust collector expansion pipe with the scalable wire connection device that contacts well, switches on stable and convenient disassembly.
Technical solution adopted in the utility model is:
A kind of dust collector expansion pipe with scalable wire connection device, comprise outer tube, the interior pipe in this outer tube of being slidingly located in, described outer tube and described in axially extended between the pipe be used to place described wire connection device cavity, be arranged on a pair of wire connection device that connects both positive and negative polarity respectively in this cavity.Described wire connection device comprise conductor rod, the rigidity made by the rigidity rod-shaped conductors shaft-like be subjected to electric body, resilient contact; One end of described resilient contact and the described end of electric body that is subjected to are electrically connected; Along the circumferential direction ring-shaped distributed outstanding at least 2 flexure strips that are provided with in the other end of described resilient contact, this flexure strip mid portion in the longitudinal direction concaves, and each described flexure strip inner surface of recess is within it all put contact mutually with the outer surface of described conductor rod one end; The other end of described conductor rod and intercalation part or receptacle portion are electrically connected, and described the other end that is subjected to electric body and intercalation part or receptacle portion are electrically connected.
The number of described flexure strip is 3.Described wire connection device also comprises the fastening rubber ring on the outer surface of a dismountable inside recess that is placed in all described flexure strips.Be enclosed with insulating barrier at the described outer surface of electric body that is subjected to.
The dust collector expansion pipe of implementing according to the utility model with scalable wire connection device has following advantage:
1, adopt the multiple spot contact, therefore compared with prior art contact-making surface is big, and energising is stable.
2, the sliding stability of rigid wire bar is convenient, and convenient disassembly.Can separate fully with being subjected to electric body.
