Abstract

The utility model relates to an electric appliance connector comprising a spring body and an inner core. The spring body comprises a spring head and a spring basic body which are hollow and coaxial. The spring head is formed by a plurality of uniformly-divided scalloped sheets cut by a circular ring. The inner surface of the spring head is a conical surface. The axial displacement of the inner core in the spring body may achieve the radial expansion or contraction of the scalloped sheets on the spring head. The electric appliance connector has beneficial effects of no need for plugging force, quick, convenient, safe, and firm field installation of electric appliance, easy manufacture, and a long service life.

Description

A kind of electrical equipment connector

Technical field

The utility model relates to a kind of electrical equipment connector, particularly a kind of be connected with electrical equipment need not plug power connector.

Background technology

National grid up-to-date " low-pressure metering box technical specification " in 2013, clearly regulation " electric energy meter is installed, electrical connection should realize by electric energy meter dedicated connector; wire must not directly access electric energy meter; electric energy meter socket connector plug should adopt interference fit plug, so as to realize electric energy meter fast, conveniently, safely, firm installation function ".But because existing a large amount of kilowatt-hour meter connects by the deviation of aperture, socket joint hole and pitch-row larger, adopt simple bullet cover, interference fit connects, can cause excessive contact engaging and separating force, and should not realize " electric energy meter fast, convenient, safety, firm installation function ", and manufacture and require highly, useful life is short.

Utility model content

Technical problem to be solved in the utility model is: a kind of electrical equipment connector is provided, need not contact engaging and separating force, and can be fast, convenient, safety, the scene of realizing securely electrical equipment installs, and easily manufactured, long service life.

The utility model solves the technical scheme that its technical problem adopts: a kind of electrical equipment connector, comprise spring plate and inner core, described spring plate comprises shell fragment head and the shell fragment matrix that hollow is coaxial, the fanning strip that described shell fragment head cuts into several deciles by annulus forms, described shell fragment head inner surface is taper seat, and the axial displacement of described inner core in spring plate can realize radial dilatation or the contraction of fanning strip on shell fragment head.

Further, described inner core is provided with the end contacting with shell fragment head inner surface, described shell fragment matrix inside is provided with internal thread, and described inner core outside is provided with the external screw thread matching with shell fragment matrix inside.

Further, the end of described inner core is the taper seat matching with shell fragment head inner surface.

In order to be fitted and connected with electrical equipment socket joint hole, described shell fragment head outer surface is taper seat.

Described spring plate and inner core are made up of copper product.

For spanner easy to use, described shell fragment outer surface of matrix is prismatic.

For the ease of fixing inner core, described interior core outer surface is provided with flat body or polygon body.

The beneficial effects of the utility model are:

1, adopt gap to peg graft, without contact engaging and separating force, can easily peg graft and exit; And common simple connector is to adopt interference fit to peg graft, have very large contact engaging and separating force, cause the difficulty of on-the-spot kilowatt-hour meter I&M, thereby have influence on the popularization of the new table of state's net case standard;

2, shell fragment head evenly opens, and fits tightly tensioner in the inner surface in electrical equipment socket joint hole, realizes safe and reliable connection; And common simple connector is due to the inner surface in the laminating of tensioner not electrical equipment socket joint hole, can be gapped when energising, cause temperature acutely to rise, easy burn-out circuit;

3, adopt tensioner mode to connect, shell fragment head regulates leeway large, thereby the manufacture of electrical equipment connector size is required to reduce; And the size of common simple connector must match with electrical equipment socket joint hole, exceed that specification error must not use or result of use is not good;

4, shell fragment head of the present utility model, can keep for a long time even tensioner and get loose, and lifetime is long; And common simple connector, because the magnitude of interference is large, again because bias is inserted, often plug several times will be out of shape, and affects follow-up electrical connection;

5, easy for installation, as long as can implement to install with conventional little wrench; And common simple connector need carry complicated plug specific purpose tool and install.

It is large that this technology has solved generic connectivity head contact engaging and separating force, be electrically connected dangerous stable, require high and useful life is short, the technical problem of inconvenience etc. is installed to making, realized easy to install fast, electrical connection safety and stability performance is high, result of use good, the life-span is long.

Embodiment

As shown in Figure 1,2,3, 4, a kind of electrical equipment connector, comprise spring plate 1 and inner core 2, described spring plate 1 comprises shell fragment head 11 and the shell fragment matrix 12 that hollow is coaxial, the fanning strip 111 that described shell fragment head 11 cuts into 6 deciles by annulus forms, described shell fragment head 11 inner surfaces are taper seat, and the axial displacement of described inner core 2 in spring plate 1 can realize radial dilatation or the contraction of fanning strip 111 on shell fragment head 11.Described inner core 2 is provided with the taper seat end of matching with shell fragment head 11 inner surfaces, described shell fragment matrix 12 is provided with internal thread 122, and described inner core 2 middle parts are provided with the external screw thread 22 matching with shell fragment matrix 12.For spanner easy to use, described shell fragment matrix 12 outer surfaces are prismatic.For the ease of fixing inner core, described inner core 2 outer surfaces are provided with two flat bodies 23.

For the ease of inserting electrical equipment socket joint hole, shell fragment head 11 outer surfaces also can be taper seat.

Described fanning strip 111 can be any number, as four, six, eight etc.

Described spring plate 1 is made with inner core 2 use copper products.

Described inner core 2 outer surfaces also can be made as polygon body.

Described fanning strip end can be provided with chamfering.

As shown in Figure 5, in the time using electrical equipment connector of the present utility model, only need insert in electrical equipment socket joint hole light shell fragment head 11, by the internal thread 122 of shell fragment matrix 12 of spring plate 1 and the screw-in that is threaded of the external screw thread 22 at inner core 2 middle parts, make the taper seat of inner core 2 ends 21 contact gradually the fanning strip 111 that backs down shell fragment head 11, thus by shell fragment head 11 tensioners in electrical equipment socket joint hole.In the time that needs disconnect, only need oppositely turn on threaded connection place, can make shell fragment head 11 get loose to extracting, thereby disconnect electrical connection.

Technical scope of the present utility model is not limited to foregoing, and the change that related personnel carries out in the scope that does not depart from the utility model technological thought or modification all belong to the scope that the utility model is protected.
