Abstract
The invention discloses a detecting device of pin holes of an enameled wire. The detecting device comprises a detecting groove and a direct-current power supply meter, wherein the detecting groove is used for containing an ionogenic detection solution and is internally provided with a partitioning plate; the partitioning plate is not connected or is incompletely connected with the bottom wall of the detecting groove; after the two ends of the enameled wire to be detected are peeled, the middle section of the enameled wire to be detected is immersed into the detecting solution; a positive electrode of the direct-current power supply meter is connected with the peeled positions of the enameled wire, a negative electrode of the direct-current power supply meter is connected with conducting metal, and then the conducting metal is immersed into the detecting solution; the enameled wire and the conducting metal are respectively arranged on the two sides of the partitioning plate. The detecting device disclosed by the invention has the beneficial effects that the structure is simple and a detection result is accurate and reliable.
Description
Technical field
The present invention relates to a kind of enamel-covered wire pinhole pick-up unit.
Background technology
Enameled wire is the staple of power domain, and inner core is conductive cores, and crust is insulation course, if insulation course is impaired, such as having pin hole or scratching etc., will affect the electric property of final manufactured goods, Given this, enameled wire is after completing, and whether must detect its insulation course has pin hole.
Summary of the invention
For solving the deficiencies in the prior art, the object of the invention is to overcome the defect of prior art, a kind of simple in structure, enamel-covered wire pinhole pick-up unit accurately and reliably is provided.
In order to realize above-mentioned target, the present invention adopts following technical scheme:
The enamel-covered wire pinhole pick-up unit, comprise detection groove, direct supply meter for holding ionogenic detection solution, in above-mentioned detection groove, a dividing plate is set, aforementioned barriers is not connected or not exclusively is connected with the diapire that detects groove, after enameled wire two ends peeling to be detected, interlude submerges and detects in solution, the positive pole of direct supply meter is connected with two ends peeling place of enameled wire, and after negative pole is connected with a conducting metal, conducting metal immerses and detects in solution, and enameled wire and conducting metal are divided into the both sides of dividing plate.
The operating voltage of aforementioned direct supply meter is 12V.
The mixed solution that aforementioned detection solution is phenolphthalein, alcohol, salt and tap water.
Aforementioned separator plate is opaque.
Aforementioned detection groove and dividing plate are made by ambroin.
Usefulness of the present invention is: enamel-covered wire pinhole pick-up unit of the present invention, simple in structure, testing result accurately and reliably.
The accompanying drawing explanation
Fig. 1 is the structural representation of the specific embodiment of enamel-covered wire pinhole pick-up unit of the present invention.
The implication of Reference numeral in figure: 1, detect groove, 2, the direct supply meter, 3, dividing plate, 4, enameled wire, 5, conducting metal.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is done to concrete introduction.
Referring to Fig. 1, enamel-covered wire pinhole pick-up unit of the present invention, comprise detection groove 1, direct supply meter 2 for holding ionogenic detection solution, the mixed solution that detection solution is phenolphthalein, alcohol, salt and tap water, the operating voltage of direct supply meter 2 is 12V, detect the interior dividing plate 3 that arranges of groove 1, dividing plate 3 is not connected or not exclusively is connected and is communicated with the detection solution that guarantees dividing plate 3 both sides with the diapire that detects groove 1.Preferably, dividing plate 3 is opaque, detects groove 1 and dividing plate 3 and makes by ambroin.
The course of work is as follows: after enameled wire 4 two ends peelings to be detected, interlude submerges and detects in solution, the positive pole of direct supply meter 2 is connected with two ends peeling place of enameled wire 4, after negative pole is connected with a conducting metal 5, conducting metal 5 immerses and detects in solution, prevent from for a long time negative pole being placed in detection solution and cause its corrosion, enameled wire 4 and conducting metal 5 are divided into the both sides of dividing plate 3.So, because water after energising ionizes, near metal, can produce chemical reaction, have the place of pin hole just to have Bubble formation.Conducting metal 5 and enameled wire 4 are arranged on to the both sides of dividing plate 3, can prevent that the bubble of conducting metal 5 from disturbing our observation to enameled wire 4, convenient detection.
Above demonstration and described ultimate principle of the present invention, principal character and advantage.The technician of the industry should understand, and above-described embodiment does not limit the present invention in any form, and all employings are equal to replaces or technical scheme that the mode of equivalent transformation obtains, all drops in protection scope of the present invention.
Claims (5)
