Abstract
The utility model discloses a mounting structure of a secondary wiring cover and a wiring box of a current transformer. The secondary wiring box is provided with a screw hole for mounting and fixing the secondary wiring cover, and the secondary wiring cover is provided with a through hole corresponding to the screw hole. A screw penetrates through the through hole of the secondary wiring cover, and is screwed with the screw hole of the secondary wiring box. The secondary wiring cover is mounted and fixed on the secondary wiring box. The secondary wiring cover can be conveniently and rapidly fixed on products by the utility model.
Description
Technical field
The utility model relates to the technical field of current transformer, and is special relevant with the installation fit structure of its secondary connection cover and terminal box.
Background technology
Traditional current transformer is column support type as depicted in figs. 1 and 2, there is one iron plate 10 (as shown in Figure 3) is installed in the bottom surface, have two little screws 101 on the mounting panel 10, a secondary connection box 20 (as shown in Figure 4) is arranged on the top of side mounting panel 10, little screw 101 on the secondary connection box 20 on the corresponding mounting panel 10 has two through holes 201, this secondary connection box 20 is above being embedded in by some concavo-convex resin ditches 50 of pouring into a mould on the product, after drawing from product inside, the secondary connection terminal is fixed on 20 li in secondary connection box, at last, cover a secondary connection cover 30 (as shown in Figure 5 and Figure 6) again, through hole 201 on the secondary connection cover 30 corresponding secondary connection boxes 20 also has two through holes 301, screw 40 is passed through hole 301 successively, through hole 201 screws togather with little screw 101, and secondary connection cover 30 is fixed on the secondary connection box 20.
Anatomize the installation fit structure between above-mentioned secondary connection box 10 and the secondary connection cover 30, be not difficult to find that there is following deficiency in it:
One, because on mounting panel 10, bores two little screws 101, during installation, these two little screws 101 must align with two through holes 201 of band on the secondary connection box 20, when again secondary connection cover 30 being covered, two through holes 301 of band also must align with two little screws 201 on the secondary connection cover 30, then, with the screw 40 of an appropriate length secondary connection cover 30, secondary connection box 20 and mounting panel 10 are fixed together again.So need to be alignd in three groups of holes one by one, make fitting operation very inconvenient.
Two, secondary connection box 20 is in the concavo-convex resin ditch 50 that is embedded on the product; promptly set up also just inactive; mounting panel 10 passes through some screw on the bottom surface of product; set up and to have moved; the amount of contraction of the each cast of epoxy resin of product cast usefulness is all different; different epoxy resin amounts of contraction is also different; cause the through hole 201 of secondary connection box 20 and the little screw 101 of mounting panel 10 to occur not positive situation like this, that is to say and to be fixed together secondary connection cover 30, secondary connection box 20 with mounting panel 10 through regular meeting.
In view of this, the inventor improves at the installation fit structure of conventional current instrument transformer secondary connection box and separate terminal enclosure, and this case produces thus.
The utility model content
Can not be fixed on problem on the product in order to solve conventional column formula secondary wiring of current mutual inductor cover, secondary connection box well by screw, the utility model provides a kind of secondary wiring of current mutual inductor cover and terminal box that fit structure is installed, and the secondary connection cover can be fixed on the product quickly and easily.
In order to reach above-mentioned purpose, solution of the present utility model is:
Secondary wiring of current mutual inductor cover and terminal box are installed fit structure, on the secondary connection box, have the screw that is used to install and fix the secondary connection cover, on the secondary connection cover, have the through hole corresponding with screw, screw passes the through hole of secondary connection cover and the screwhole spiro bonding of secondary connection box, and the secondary connection cover is installed and fixed on the secondary connection box.
The screw of described secondary connection box is formed on the inserts, and inserts is injection-moulded in the secondary connection box.
After adopting such scheme, the utility model is in the concavo-convex resin ditch that is embedded on the product based on the secondary connection box, itself can not move again, like this, as long as align the screwhole position of its through hole and secondary connection box by the movable secondary connection cover in front and back, just secondary connection cover and secondary connection box can be fixed together, and be not related with mounting panel, thereby avoid three groups of holes alignment difficulty big and, the secondary connection cover can be fixed on the product quickly and easily because of the resin shrinkage of cast causes the situation of hole misalignment.Simultaneously, the utility model is because not be used in the little screw of installation twist drill, and structure is also simpler.

Embodiment
As shown in Figure 7 and Figure 8, be preferred embodiment of the present utility model.The utility model is applicable to the current transformer of column support type, cooperate shown in Figure 1, there is one iron plate 10 is installed in the bottom surface, in some concavo-convex resin ditches 50 that the top of side mounting panel 10 has a secondary connection box 20 to be embedded in to pour into a mould on the product, after drawing from product inside, the secondary connection terminal is fixed on 20 li in secondary connection box, at last, cover a secondary connection cover 30 again.
Improvement of the present utility model is: do not need perforate again on the mounting panel 10, only on secondary connection box 20, have two screws 21, this screw 21 is to be used to install and fix secondary connection cover 30, the moulding of screw 21 for convenience, present embodiment is that screw 21 is formed on the inserts 60, inserts 60 is injection-moulded in 20 li in secondary connection box, and certainly, screw 21 can be formed directly on the secondary connection box 20.
Still (see Fig. 5 and Fig. 6) as the conventional current instrument transformer on the secondary connection cover 30 and have through hole 301, this through hole 301 is corresponding with screw 21.
During concrete the installation, the through hole 301 that the screw 40 of suitable length is passed secondary connection cover 30 screws togather with the screw 21 of secondary connection box 20, can secondary connection cover 30 be installed and fixed on the secondary connection box 20 very convenient, fastly.
The foregoing description and graphic and non-limiting product form of the present utility model and style, any person of an ordinary skill in the technical field all should be considered as not breaking away from patent category of the present utility model to its suitable variation or modification of doing.
