Abstract
A metal wiring insert comprises a main body with an internal threaded hole, wherein the main body has an external quadrangular shape; an external lead hole is formed on one surface of the main body; the external lead hole is communicated with the internal threaded hole; the rear part of the external quadrangular main body is a cylindrical transition section; and the rear part of the transition section is connected with an end head of an internal lead hole. When the metal wiring insert is applied to a mutual inductor, a sensor and other components cast by epoxy resin, the metal wiring insert can be effectively cast and fixed inside the epoxy resin to achieve aims of preventing rotation, preventing pulling and preventing unsoldering; and the metal wiring insert is simple in structure and convenient to install.
Description
Technical field
The utility model relates to the power transmission and distribution technology industry, is a kind of electric component, is used for the binding post of the metal insert of poured with epoxy resin such as instrument transformer, transducer.
Background technology
The metal connection inserts is used for instrument transformer, transducer of poured with epoxy resin etc., is the terminals that are connected with the outside.The binding post of metal current inserts all is the cylinder copper body of band internal thread hole, and lead directly is welded on the end face of cylinder, at circumferencial direction with axially all there is not a spacing point.When reality was used, the binding post that can run into metal insert can rotate in body of epoxy resin and move axially, and is pulled out easily, occurs the sealing-off phenomenon easily at the end face weld in addition, has certain quality hidden danger.
The utility model content
The utility model is the shortcoming to above-mentioned existence, and the metal connection inserts is provided, and it is simple in structure, can reach anti-rotation, the anti-function of pulling out, preventing sealing-off effectively, makes the quality safety and reliability of product.
The technical scheme that technical problem adopted that the utility model solves is:
A kind of metal connection inserts comprises the main body of being with internal thread hole, it is characterized in that the profile of main body is outer square shape, and a face on the main body is provided with the outer lead hole, and outer lead hole and internal thread hole are communicated with.Adopt outer square shape, after poured with epoxy resin, just can not rotated, prevent loosening being pulled out simultaneously by external force.During use, outer lead stretches into the outer lead hole, outer lead is fixedly connected through internal thread hole with screw.
During practical implementation, the rear portion of the main body of outer square shape is columniform changeover portion, and the changeover portion rear portion is connected with the termination in lead hole.During use, connecting line is fixed through the lead hole, welds then, has improved the reliability of its electrical connection like this, prevents the sealing-off phenomenon.
The beneficial effect of the utility model is: the utility model is used in occasions such as the instrument transformer, transducer of poured with epoxy resin, can pour into a mould effectively to be fixed in the epoxy resin, reaches anti-rotation, anti-ly pulls out, the purpose of anti-sealing-off, and is simple in structure, easy for installation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment utility model is further specified.
Fig. 1 is the structural representation of the utility model embodiment.
Fig. 2 is the plan structure sketch map of the utility model embodiment Fig. 1.
Fig. 3 is the side-looking structural representation of the utility model embodiment Fig. 1.
Among the figure: 1, internal thread hole 2, outer lead hole 3, lead hole 4, main body 5, changeover portion 6, termination.
Embodiment
In Fig. 1, Fig. 2 and Fig. 3; A kind of metal connection inserts comprises the main body 4 of being with internal thread hole 1, and the profile of main body 4 is outer square shape; A face on the main body 4 is provided with outer lead hole 3; Outer lead hole 3 is communicated with internal thread hole 1, and the rear portion of the main body 4 of outer square shape is columniform changeover portion 5, and changeover portion 5 rear portions are connected with the termination 6 in lead hole 2.Adopt outer square shape, after poured with epoxy resin, just can not rotated, prevent loosening being pulled out simultaneously by external force.During use, outer lead stretches into outer lead hole 3, is fixedly connected through 1 pair of outer lead of internal thread hole with screw, and connecting line is fixing through lead hole 2, welds then, has improved the reliability of its electrical connection like this, prevents the sealing-off phenomenon.
Claims (2)
