Abstract
The utility model discloses an a kind of connector of distribution drawer unit, it relates to distribution technique field.The moving contact that it comprises shell made of insulating material and installs in the enclosure, feature is: moving contact comprises: the special-shaped copper sheet of at least one group of relative placement is packed in the both sides of U-shaped steel disc by connecting pin and the spring being installed on its two ends, the bottom of U-shaped steel disc has been bolted inverted L-shaped copper coin and a round platform, and by bolt and shell fastening.Its advantage is: make copper sheet only bear conducting function, and the spring of its both sides realizes good contact and the clamping function of contact and a word copper bus-bar; When also can ensure to there is error between contact and copper bus-bar, connector can automatically adjust with copper bus-bar patch position, ensure uniform force in grafting process.The utility model can ensure the job stability of connector, enhances the endurance of its machinery, avoids because loose contact burns out contact, ensures to connect primary power source reliably and with long-term; Connector long service life.
Description
Technical field
The utility model relates to distribution technique field, be specifically related to a kind of distribution drawer unit connector.
Background technology
A connector, mainly refers to a upper connector used of circuit (i.e. main line) in power distribution cabinet, plugs together completing circuit conducting by sound plug-in unit.Corresponding electric current decides according to different cabinet types and circuit, and general voltage is 380V, 660V or higher.Electric current is divided into 160A, 250A, 400A, 630A.Be up to 630A (be also in theory, generally all do not reach).The toughness of a traditional connector is not high, and resistance to impact is not high yet, can not ensure the stability that conductive contact contacts, and easily clashes into contact and cause damage when swinging up and down about extracting unit motion track out.
Utility model content
For the deficiency that prior art exists, the utility model object is to provide a kind of distribution drawer unit a connector, the job stability of connector can be ensured, enhance the endurance of its machinery, the resistance conducted electricity is reduced, avoid because loose contact burns out contact, ensure to connect primary power source stably in a long term; The long service life of connector.
To achieve these goals, the utility model realizes by the following technical solutions: the moving contact that connector comprises shell made of insulating material and installs in the enclosure, it is characterized in that: described moving contact comprises: the special-shaped copper sheet of at least one group of relative placement is packed in the both sides of U-shaped steel disc by connecting pin and the spring being installed on connecting pin two ends, be bolted a supporting bracket and round platform in the bottom of U-shaped steel disc, and by bolt and shell fastening.
The fore-end of described special-shaped copper sheet is V-arrangement, and interlude is horizontal component, and its rear end part is semicircle arc structure.
The hole installing connecting pin is shaped with at the horizontal component of special-shaped copper sheet.
The centre position, bottom of described U-shaped steel disc has one for installing the hole of bolt, centre bore both sides are shaped with circular positioning convex, two sides of U-shaped steel disc all have three holes equal and in one line, interval, the center in hole point-blank, be parallel to bottom surface, for installing connecting pin with fixing special-shaped copper sheet.
Described supporting bracket is inverted L-shaped copper coin.
The end face centre position of described inverted L-shaped copper coin has the hole that installs bolt, and have the location hole that positioning convex circular with U-shaped steel disc matches in these both sides, hole, the centre position, side of inverted L-shaped copper coin is shaped with a wiring screwed hole.
Described insulator foot adopts Noryl base; Noryl, poly-2.6 dimethyl-1.4-phenylates, be called for short MPPO, a kind of high temperature, heat-resistant resin, have excellent physical property and characteristic, be a kind of thermal shrinkage type engineering plastics of high comprehensive performance, outstanding feature is insulating properties, resistance to water, the stability of size and strength and toughness thereof, resistance to impact etc. are all good.
The beneficial effects of the utility model:
1, the job stability of connector can be ensured, enhance the endurance of its machinery, the resistance conducted electricity be reduced, avoids because loose contact burns out contact, ensure to connect primary power source stably in a long term;
2, the independent stage clip of the insulator foot every of connector, conductive contact have the activity adjustment space of trace, and great like this preventing clashes into because extracting the amount of swinging up and down about unit running orbit out the damage caused to contact.
Accompanying drawing explanation
The utility model is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is structural representation of the present utility model.
In figure: 1, shell; 2, special-shaped copper sheet; 3, U-shaped steel disc; 3-1, positioning convex; 3-2, connecting pin bores; 4, inverted L-shaped copper coin; 4-1, bolt hole; 4-2, location hole; 4-3, wiring screwed hole; 5, connecting pin; 6, round platform; 7, spring; 8, fixed card; 9, outer-hexagonal bolt; 10 wiring fastening bolts; 11 jump rings.
Embodiment
The technological means realized for making the utility model, creation characteristic, reaching object and effect is easy to understand, below in conjunction with embodiment, setting forth the utility model further.
With reference to Fig. 1, this embodiment is by the following technical solutions: described moving contact comprises: the special-shaped copper sheet 2 of at least one group of relative placement is packed in the both sides of U-shaped steel disc 3 by connecting pin and the spring 7 that is installed on connecting pin two ends, be bolted a supporting bracket and round platform 6 in the bottom of U-shaped steel disc 3, and by bolt and shell fastening.
The structural design of connector is unique, it is 660/380 three-phase or four phase power supplys, have individual segmentation cell, greatly add creepage distance and air gap, under severe dust, moist condition, effectively prevent alternate electric leakage, short trouble that arcing causes.
The conductive contact of this embodiment unique texture.Each contact has the V-type angle of release of about 40-45 °, each contact has about one group independently stage clip, be convenient to and copper bus-bar grafting, ensure pressure stability simultaneously, and enhance the endurance of machinery, the resistance of conduction is reduced, avoids because contact is burnt in loose contact, ensure the connection primary power source of long time stability.The independent stage clip of the insulator foot every of connector, conductive contact have the activity adjustment space of trace, and great like this preventing clashes into because of the amount of swinging up and down about extraction unit running orbit the damage caused to contact.
More than show and describe general principle of the present utility model and principal character and advantage of the present utility model.The technical staff of the industry should understand; the utility model is not restricted to the described embodiments; what describe in above-described embodiment and specification just illustrates principle of the present utility model; under the prerequisite not departing from the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
