Description

Frock clamp of test ET type magnetic core electric property

Technical Field

The invention relates to the field of production of high-permeability cores of manganese-zinc ferrite, in particular to a tool clamp for testing the electrical property of an ET-type magnetic core.

Background

After the ET type manganese-zinc high-conductivity soft magnetic ferrite is sintered, the electrical property needs to be fully checked.

During detection, a customer requires that an enameled wire is wound for 5 circles. If 5 circles of enameled wires are wound on each product manually, the enameled wires are wasted, labor is wasted, cost is increased, efficiency is reduced, and losses are caused to companies.

The tool clamp is designed through a series of tests, can replace winding of 5 circles of enameled wires, is very convenient to completely detect the electrical property of the ET type product, ensures the quality of the product, saves manpower and material resources, and improves the efficiency and the benefit.

SUMMERY OF THE UTILITY MODEL

In order to solve the technical problem, the utility model provides a frock clamp for testing the electrical property of an ET type magnetic core, which comprises an upper cover, a base, a copper wire and a copper plug, wherein the upper cover comprises hard plastic and contact pins, two rows of contact pins are arranged in parallel by vertically penetrating the hard plastic, each row of contact pins is 5, and the two rows of contact pins are aligned; the base comprises a milky acrylic plate, pins, a copper plate and test connectors, wherein the acrylic plate is located on the copper plate and corresponds to the pins, two rows of pins are arranged on the base, each pin is provided with 5 through holes, the acrylic plate is provided with mutually connected wires, the bottom ends of the through holes are respectively located on the wires, two ends of each wire are respectively connected with the test connectors, and two test plugs are respectively connected with the copper connectors through copper wires.

Detailed Description

As shown in FIGS. 1-3, the utility model discloses a frock clamp of test ET type magnetic core electrical property, including upper cover, base, copper wire and copper plug.

The upper cover comprises hard plastic 2 and pins 1, two rows of pins 1 are arranged in parallel and vertically penetrate through the

hard plastic

2, 5 pins 1 in each row are arranged, and every two pins are aligned.

The base comprises a milky acrylic plate 4, two rows of pins 7, a copper plate 5 and test connectors 6, wherein the acrylic plate 4 is located on the copper plate 5 and corresponds to the pins 1, the base is provided with the pins 7 in two rows, each pin 7 is provided with 5 through holes, the acrylic plate 4 is provided with mutually connected wires, the bottom ends of the through holes are respectively located on the wires, two ends of each wire are respectively connected with the test connectors 6, and the two test plugs are respectively connected with the copper connectors through copper wires.

The invention relates to a sorting and testing process for electrical properties of a high-permeability core, which is formed by using copper pins and pins, opal acrylic, copper plates, hard plastics, copper wires and other assemblies.

The method comprises the following steps: the tooling fixture is well connected with an electrical property testing instrument, the ET-shaped magnetic core is placed in the base of the tooling fixture, the contact pins of the upper cover are aligned to the contact pins on the base, the contact pins are lightly plugged tightly, and data on the testing instrument is read.

By adopting the tool clamp disclosed by the invention, the electrical property of the 5 coils of the ET-type magnetic core can be detected. The tooling fixture may be used with other ET cores, but the specific dimensions, etc. may vary.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments described in the foregoing embodiments, or equivalents may be substituted for elements thereof. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
