Abstract

It the utility model is related to earth leakage protective device field; a kind of more particularly to electric leakage module of circular groove shape magnet ring; including housing and the magnetic ring component being arranged on housing, binding post; offer the square opening for copper busbar being fastened in magnetic ring component in the magnetic ring component, square opening one end that copper busbar passes magnetic ring component is fixed by terminal screw and binding post.The circular groove shape magnet ring of the electric leakage module of this circular groove shape can be by space bigizationner, and allowing in magnet ring has enough spaces to arrange electric conductor, while magnet ring housing is protected using double casing; the extruding that can be subject to magnet ring is preferably minimized; security is good, modular designs, and user can voluntarily assembled or dismounting.

Description

A kind of electric leakage module of circular groove shape magnet ring

Technical field

It the utility model is related to earth leakage protective device field, more particularly to a kind of electric leakage module of circular groove shape magnet ring.

Background technology

The both ends copper coin that in the market generally uses, centre is realized with Silicone Rubber wire by way of spot welding electrically to be connected Connect, the technique easily causes sealing-off, is involved in by the way of wire plus silica gel line inside the very small circular magnetic loop in a space Silica gel line skin is easily damaged, due to which, the high current that arrangements of conductors too closely, during its work passes through can cause local temperature Height is spent, causes silica gel line skin quick aging, and influences the service life of earth leakage protective device.It is domestic at present to also have using circle Magnet ring senses leakage current signal, and circular magnet ring electric leakage module is easy to out in the confined space in the extruding by wire The situation of existing silica gel wire skin rupture.

Utility model content

In view of the shortcomings of the prior art, the utility model provides a kind of electric leakage module of circular groove shape magnet ring, including housing, Be arranged on housing magnetic ring component, binding post, offer in the magnetic ring component for copper busbar to be fastened on into magnet ring Square opening in component, square opening one end that the copper busbar passes magnetic ring component are fixed by terminal screw and binding post.

Further, the base of housing bottom side and the cover plate that is arranged on the upside of housing are arranged in addition to.

Further, the magnet ring in the magnetic ring component is circular groove shape.

Further, isolated inside the magnetic ring component with wire with shell.

Further, the circular groove shape magnet ring can be to being isolated per a piece of copper busbar by insulating materials.

Further, the square opening for being independently used for increasing the creep age distance between every circuitry phase is provided with the copper bar.

Further, the entirety of the electric leakage module of the circular groove shape magnet ring can be carried out with reclosing primary module it is assembled and Dismounting.

The beneficial effects of the utility model are：

The circular groove shape magnet ring of the electric leakage module of circular groove shape of the present utility model can be by space bigizationner, and allowing in magnet ring has foot Electric conductor is arranged in enough spaces, while magnet ring housing is protected using double casing, can be preferably minimized the extruding that magnet ring is subject to, Security is good, modular designs, and user can realizing self disassembling or assembled use.

Embodiment

It is new below in conjunction with this practicality to make the purpose, technical scheme and advantage of the utility model embodiment clearer Accompanying drawing 1-4 in type embodiment, the technical scheme in the embodiment of the utility model is clearly and completely described, it is clear that institute The embodiment of description is the utility model part of the embodiment, rather than whole embodiments.Based on the reality in the utility model Example is applied, the every other embodiment that those of ordinary skill in the art are obtained under the premise of creative work is not made, is all belonged to In the scope of the utility model protection.

The utility model is a kind of electric leakage module of circular groove shape magnet ring, including housing 1 and is arranged on the upper magnetic ring group of housing 1 Part 2, binding post 4, the square opening for copper busbar 3 being fastened in magnetic ring component 2, institute are offered in the magnetic ring component 2 State copper busbar 3 and pass one end of circular groove and fixed by terminal screw 5 and binding post 4.

, can be with screw by housing cover after copper busbar 3 to be installed to circular groove within the case 1 in example is embodied 14 are fixed with base 1, and the top of housing 1 is fixed with screw and cover plate, magnet ring housing using double casing protect, can make magnet ring by Extruding be preferably minimized.

In example is embodied, magnetic ring component 2 is designed to middle circle groove profile magnet ring, then copper busbar 3 is blocked side by side It is located in circular groove, eliminates spot-welding technology, wiring is become very firm, while can be arbitrarily dismantled wherein according to the needs of client Module, easy to use and flexibility is big.

It should be noted that herein, such as first and second or the like relational terms are used merely to a reality Body or operation make a distinction with another entity or operation, and not necessarily require or imply and deposited between these entities or operation In any this actual relation or order.Moreover, term " comprising ", "comprising" or its any other variant are intended to Nonexcludability includes, so that process, method, article or equipment including a series of elements not only will including those Element, but also the other element including being not expressly set out, or it is this process, method, article or equipment also to include Intrinsic key element.In the absence of more restrictions, the key element limited by sentence "including a ...", it is not excluded that Other identical element also be present in process, method, article or equipment including the key element.

Above-mentioned technical proposal only embodies the optimal technical scheme of technical solutions of the utility model, the technology of the art Personnel embody principle of the present utility model to some variations that some of which part may be made, and belong to the utility model Protection domain within.
