Description
Technical field
The utility model relates to a kind of metallized film surface resistance detection head, belongs to thin film capacitor manufacturing technology field.
Background technology
Known in prior art, metallized film for the manufacture of thin film capacitor has the thickness of coating of graded or gradual change, there is progressive meaning for following in these: reduce self-healing energy consumption, reduce the contact resistance of extension line and electrode, improve the ability of loaded current, improve voltage endurance capability; The change of metallized film thickness of coating directly affects the change of metallized film resistive performance, in order to get rid of the impact of the slight change such as material quality, processing technology on properties of product, limit with the resistive performance of metallized film or judge that metallized film each definition position place thickness of coating more corresponds to actual needs, also having more actual operation.In addition, even if routine etc. the metallized film of thickness of coating, the monitoring for thin film coating thickness evenness is also necessary.Be metal quality to realize conduction for detecting the detection head of metallized film surface resistance, because metal has handling ease and the high advantage of machining precision, thus the fixture for detecting metallized film surface resistance is also generally metal and makes, thus easily puncture between detection head and between detection head and fixture, light then affect the accuracy of test result, seriously then may cause detecting the even personnel's injury of electric equipment fault.
Utility model content
The utility model is just for the deficiency that prior art exists, a kind of metallized film surface resistance detection head is provided, the electrical insulation properties of detection head can be improved, thus improve the accuracy of metallized film surface resistance testing result and detect the security of operation, meet actual operation requirements.
For solving the problem, technical solution adopted in the utility model is as follows:
A kind of metallized film surface resistance detection head, comprise: ball, conductive pole and encapsulate the collets of described ball and described conductive pole, described collets are that pottery is made, described ball is arranged at the bottom of described collets, described conductive pole lower end connects described ball, the detection line of described conductive pole upper end contact resistance checkout equipment.
As the improvement of technique scheme, also comprise the Bracket for Inspection for placing detection head, described Bracket for Inspection comprises firm banking and is arranged at the holding piece above described firm banking, the two ends of described holding piece are all fixedly connected with described firm banking by erection bolt, and described holding piece is provided with detection head chute;
Described collets comprise limited cap and coordinate the position limiting slide block of described detection head chute, described ball is positioned at bottom described position limiting slide block, described position limiting slide block is arranged in described detection head chute, and the external diameter of described limited cap is greater than the width of described detection head chute and is positioned on described detection head chute.
As the improvement of technique scheme, described position limiting slide block is the cylindrical structural vertically arranged, and the radius of described position limiting slide block is equal with the width of described detection head chute, and described ball is arranged at the bottom center of described position limiting slide block.
As the improvement of technique scheme, described firm banking and described holding piece are that metal is made, and the end face of described firm banking is provided with the first rubber blanket, and the bottom surface of described holding piece is provided with the second rubber blanket.Metal is adopted to be convenient to processing and good rigidly as the main material of firm banking and holding piece, thus be convenient to control surface flatness, exert a force when reducing clamping metallized film uneven degree, but the too hard easy scratch metallized film in metal surface and friction force is less, clamp firm poor effect, therefore arrange the first rubber blanket and the second rubber blanket, probability and the clamping that greatly can either reduce scratch metallized film are very firm, and test result is accurate.
As the improvement of technique scheme, described holding piece is provided with the mounting guide sleeve coordinating described erection bolt.Mounting guide sleeve is set and not only at the thickness ensureing to reduce under the prerequisite that screw thread is non-slip holding piece, and can improves the steadiness of holding piece, can not deflect thus cause force uneven.
Compared with prior art, implementation result of the present utility model is as follows for the utility model:
Metallized film surface resistance detection head described in the utility model, contact for contact metallization film is ball, because this reducing the probability of point discharge, namely the equipment that reduces punctures the probability drawing fire, adopt collets encapsulating conductor simultaneously, electrical insulation properties between detection head and between detection head and Bracket for Inspection is improved further, preferably ceramic is as insulating bag closure material simultaneously, both ensure that insulating property, avoid again conventional insulation materials as not enough in rigidity such as rubber plastics, the problem of abrasion resistance properties difference, make between detection head with Bracket for Inspection coordinate more tight, thus it is stable to make detection head place, and movement locus is reproducible, test result is accurate.
