Abstract
The utility model discloses a low pressure current transformer especially discloses a low pressure current transformer's secondary binding post, belongs to the electrical equipment field, and secondary binding post includes the terminal, and the terminal is equipped with the wiring hole on the cylinder, and the terminal top is equipped with 2 screw holes, is equipped with the crimping screw on every screw hole. During installation electric current secondary circuit, only need to insert the wiring hole with the secondary circuit connector lug to corresponding crimping screw is screwed up and the installation can be accomplished. Adopt this kind of secondary binding post effectively to overcome the shortcoming of old -fashioned terminal, make it possess that the wiring is simple quick, the crimping is reliable, the characteristics of assembly rule, but the wide application is in low -pressure measurement device installation.
Description
Technical field
The utility model relates to a kind of low-voltage current mutual inductor, particularly relates to a kind of secondary wiring terminals of low-voltage current mutual inductor, belongs to electric equipment field.
Background technology
In low-voltage metering mechanism installation process, installation low-voltage current mutual inductor and secondary circuit thereof are the one work that metrological personnel frequently carries out, for the low-voltage current mutual inductor adopted at present, when crimping secondary wiring of current mutual inductor terminal and secondary circuit wire, need curved for a terminal annulus, then be clipped in the middle with pad, again crimping screw is crimped onto on secondary wiring terminals of transformers through pad and annulus, there is obvious shortcoming in aforesaid operations: the skill that terminal curves annulus is difficult to grasp, easily drop through when pad and annulus, bothersome effort, joint annulus is easily exited the end of a thread by the screw rotated, and causes crimping bad, causes secondary loop of mutual inductor error larger, proficiency differs, and installs lack of standardization.
Utility model content
The purpose of this utility model is to provide a kind of low-voltage current mutual inductor, especially improves the secondary wiring terminals of low-voltage current mutual inductor, effectively can overcome the deficiencies in the prior art, and wiring is simple and quick, crimping is reliable, the effect of installation specification to make it reach.
Low-voltage current mutual inductor described in the utility model, comprise primary connection terminal and secondary wiring terminals, secondary wiring terminals is positioned at above primary connection terminal, secondary wiring terminals comprises binding post, binding post is provided with wiring hole on cylinder, be provided with 2 screw holes above binding post, each screw hole be equipped with crimping screw.When installing electric current secondary loop, second loop return wiring head is inserted wiring hole, and tighten 2 corresponding crimping screws, can installation be completed.Crimp pattern by old-fashioned two-pad list screw, change wire into and directly access two screw crimping pattern.
Binding post is copper, facilitates wiring and conductivity is better.
The utility model compared with prior art, has following beneficial effect:
Improve the secondary wiring terminals of low-voltage current mutual inductor, change wire into by old-fashioned two-pad list screw crimping pattern and directly access two screw crimping pattern, wiring is simple and quick, crimping is reliable, the feature of installation specification to make it possess, and can be widely used in low-temperature measurement installation process.
Accompanying drawing explanation
Fig. 1 is the front view of current transformer.
Fig. 2 is the vertical view of current transformer.
Fig. 3 is binding post structure schematic diagram.
In figure: 1, primary connection terminal 2, wiring hole 3, secondary wiring terminals 4, crimping screw 5, screw hole 6, binding post.
Embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
As Figure 1-3, low-voltage current mutual inductor described in the utility model, comprise primary connection terminal 1 and secondary wiring terminals 3, secondary wiring terminals 3 is positioned at above primary connection terminal 1, secondary wiring terminals 3 comprises binding post 6, each binding post 6 is provided with wiring hole 2 on cylinder, 2 screw holes 5 are provided with above binding post 6, screw hole 5 is equipped with crimping screw 4, when installing electric current secondary loop wire, second loop return wiring head is inserted wiring hole 2, and 2 the crimping screws 4 tightening correspondence can complete installation, binding post 6 is copper, facilitate wiring and conductivity is better.
As shown in Figure 3, produce in casting process at low-voltage current mutual inductor, by figure 3 binding post 6 substitute old-fashioned binding post, and reserve circular hole at screw hole 5, wiring hole 2 correspondence position, each screw hole 5 be equipped with crimping screw 4.Overcome the shortcoming of original old-fashioned binding post, change wire into and directly access two screw crimping pattern, wiring is simple and quick, crimping is reliable, installation specification.
Adopt the low-voltage current mutual inductor of the above preferred embodiment of the present utility model described by reference to the accompanying drawings, improve the secondary wiring terminals of low-voltage current mutual inductor, change wire into by old-fashioned two-pad list screw crimping pattern and directly access two screw crimping pattern, wiring is simple and quick, crimping is reliable, the feature of installation specification to make it possess, but the utility model is not limited to described execution mode.The change that these carry out execution mode when not departing from principle of the present utility model and spirit, amendment, replacement and distortion still fall in protection range of the present utility model.
