Abstract
The utility model discloses a kind of electric energy meter plug terminal and electric energy meter, its one end of electric energy meter plug terminal is the terminals be connected with external cord, the other end be with electric energy meter on connect the inserted terminal of electric hole grafting; Curl shape rolling pars convoluta in the axial dual-side warp-wise of inserted terminal, the outside surface of curled portion is be suitable for and the arcwall face connecing electric hole hole wall and fit; Also disclose a kind of electric energy meter with above-mentioned plug terminal, the top connecing electric hole is provided with and inserted terminal is compressed make inserted terminal and the crimping screw connecing electric hole hole wall and fully contact simultaneously.In electric energy meter plug terminal of the present utility model, curl shape rolling pars convoluta in the axial dual-side warp-wise of inserted terminal, the outside surface of curled portion is be suitable for and the arcwall face connecing electric hole hole wall and fit, such inserted terminal just can with connect the grafting of electric hole after contact good, simultaneously because curled portion has larger deformation range, with connect the grafting of electric hole after by crimping screw in compression, thus guarantee inserted terminal and connect electric hole hole wall and can more fully contact and be formed and be electrically connected more reliably.
Description
Technical field
The utility model relates to a kind of electric energy meter plug terminal and electric energy meter, belongs to electric energy instrument field of structural design.
Background technology
A kind of electric energy meter plug terminal is disclosed in patent documentation CN103487620A, this plug terminal by coordinate in the terminal for inserting electric energy meter patch part and coupling part form, patch part one-body molded with coupling part, the described part that patches is made up of ball-shaped end and conically shaped body, described conically shaped body offers cross recess, described coupling part is provided with wire access aperture and fixed orifice, the described circle face, the inner patching part is provided with mating holes, and this mating holes is arranged on the junction patching part and coupling part.Due on electric energy meter connect electric hole and when shaping, often there is error in plug terminal, if when equipped the relatively little plug terminal of diameter and diameter relatively large connect the grafting of electric hole, so just there will be the problem of the loose contact because there is gap between the two.
Utility model content
To this, the purpose of this utility model is to provide the reliable electric energy meter plug terminal of a kind of electrical connection and electric energy meter.
The technical scheme realizing the utility model object is:
A kind of electric energy meter plug terminal, its one end is the terminals be connected with external cord, the other end be with electric energy meter on connect the inserted terminal of electric hole grafting; Curl shape rolling pars convoluta in the axial dual-side warp-wise of described inserted terminal, the outside surface of described curled portion is be suitable for and the described arcwall face connecing electric hole hole wall and fit.
In technique scheme, described terminals center is provided with the wiring hole being suitable for described external cord and inserting.
In technique scheme, the outside punching press of plug terminal is formed with positioning boss or detent.
There is an electric energy meter for above-mentioned electric energy meter plug terminal, described in connect electric hole top be provided with described inserted terminal compressed to make described inserted terminal and the described crimping screw connecing electric hole hole wall and fully contact.
The utility model has positive effect: in (1) electric energy meter plug terminal of the present utility model, curl shape rolling pars convoluta in the axial dual-side warp-wise of described inserted terminal, the outside surface of described curled portion is be suitable for and the described arcwall face connecing electric hole hole wall and fit, so, inserted terminal just can contact well with connecing electric hole, simultaneously because curled portion has larger deformation range, with connect the grafting of electric hole after make curled portion generation deformation by crimping screw in compression, thus guarantee inserted terminal and connect electric hole hole wall and can more fully contact and be formed and be electrically connected more reliably.
Accompanying drawing explanation
Fig. 1 is the structural representation of electric energy meter plug terminal in the utility model;
Fig. 2 is electric energy meter plug terminal of the present utility model and structural representation during crimping screw fit.
Reference numeral shown in figure is: 1-terminals; 2-inserted terminal; 21-curled portion; 3-positioning boss; 4-crimps screw.
Embodiment
As shown in Figure 1, a kind of electric energy meter plug terminal in the present embodiment, its one end is the terminals 1 be connected with external cord, the other end be with electric energy meter on connect the inserted terminal 2 of electric hole grafting; Curl shape rolling pars convoluta 21 in the axial dual-side warp-wise of described inserted terminal 2, the outside surface of described curled portion 21 is be suitable for and the described arcwall face connecing electric hole hole wall and fit.In the electric energy meter plug terminal of the present embodiment, curl shape rolling pars convoluta 21 in the axial dual-side warp-wise of described inserted terminal 2, the outside surface of described curled portion 21 is be suitable for and the described arcwall face connecing electric hole hole wall and fit, so, inserted terminal 2 just can contact well with connecing electric hole, simultaneously because curled portion has larger deformation range, with connect the grafting of electric hole after compress make curled portion 21 that deformation occur by crimping screw 4, thus guarantee inserted terminal 2 and connect electric hole hole wall and can more fully contact and be formed and be electrically connected more reliably.
In the present embodiment, described terminals 1 center is provided with the wiring hole being suitable for described external cord and inserting, and when being connected with external cord, external cord to be inserted in wiring hole also riveting terminals 2 thus make it reliably be connected with external cord.
Further, plug terminal outside is provided with positioning boss 3, described positioning boss 3 is that when connecting external cord, described terminals 2 are formed through riveting, can certainly be process, also can position at described plug terminal outer setting detent, to increase plug terminal installation reliability in practical operation.
Further again, a kind of electric energy meter with above-mentioned electric energy meter plug terminal, described in connect electric hole top be provided with described inserted terminal 2 compressed to make described inserted terminal 2 and the described crimping screw 4 connecing electric hole hole wall and fully contact, as shown in Figure 2.
Obviously, above-described embodiment of the present utility model is only for the utility model example is clearly described, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here exhaustive without the need to also giving all embodiments.And these belong to connotation of the present utility model the apparent change of extending out or variation still belong to protection domain of the present utility model.
