Abstract

The utility model relates to a current transformer, and solves the technical problems that the existing current transformer is electrically connected with equipment or a measuring apparatus by means of wiring terminals, which results in that wiring is inconvenience, and cascade is very likely to occur, thus affecting the measurement result, and the like. The current transformer is characterized in that a line bank with a plurality of clamping ports is embedded in the housing; the line bank and the housing are fixed together; and incoming and outgoing wires of a coil are respectively electrically connected with corresponding clamping port wiring terminals. The current transformer has the beneficial effects that as the line bank with the plurality of clamping ports is embedded in the housing, when wire connection is conducted, the wires can be directly inserted into the clamping ports, and with the clamping ports of the line bank, the wires can be electrically connected with wiring terminals in the line bank, so that not only is wiring convenient and the wiring operation efficiency improved, but also cascade between the wires can be prevented, and normal detection of instruments and meters is ensured.

Description

A kind of current transformer

Technical field

The utility model relates to a kind of current converter, relates in particular a kind of current transformer.

Background technology

The effect of current transformer is to be converted to the less secondary current of numerical value to the larger primary current of numerical value by certain no-load voltage ratio; be used for protecting, the purposes such as measurement, in order to realize standardization, the miniaturization of measuring instrument, protection equipment and automatic control equipment.Be fixed with screw terminal on the housing of existing current transformer, equipment or measuring instrument/table are wrapped in binding post by wire, and connect wire by screw-driving, adopt this connected mode, when not only wiring inconvenience, and multiple conducting wires is connected on binding post, owing to being subjected to spatial limitation, easily contact between wire, affect the measurement result of instrument and meter.

The utility model content

Adopt the mode of binding post to be electrically connected to equipment or measuring instrument in order to solve existing current transformer, cause wiring to be inconvenient to reach easily and contact, affect the technical problems such as measurement result; The utility model provides a kind of current transformer, and this current transformer not only can facilitate wiring, simultaneously, also can prevent from being short-circuited between wire, guarantees the normal detection of instrument and meter.

For solving above technical problem, the technical scheme that the utility model is taked is a kind of current transformer, include housing and be placed in the interior coil of housing, it is characterized in that being inlaid with the line bank with a plurality of bayonet sockets in described housing, this line bank and housing fix, coil into and out of line respectively with line bank on corresponding bayonet socket binding post be electrically connected to.

Further, described line bank is provided with plural screw, and is fixedly connected with housing by screw.

The beneficial effects of the utility model are to inlay line bank with bayonet at surface of shell, like this when connecting wire, wire can directly insert in bayonet socket, utilize the bayonet socket of line bank will cause being electrically connected to binding post in line bank, so not only facilitate wiring, improve the wiring operating efficiency, simultaneously, also can prevent from contacting between wire, guarantee the normal detection of instrument and meter.

Description of drawings

Fig. 1 is the front view of a kind of current transformer of the utility model embodiment

Embodiment

Below in conjunction with accompanying drawing, the utility model execution mode is described further:

As shown in Figure 1, the utility model is a kind of current transformer, include housing 1 and be placed in the interior coil of housing, adopt the mode of binding post to be electrically connected to equipment or measuring instrument in order to solve existing current transformer, cause wiring inconvenience and wire easily to be contacted, affect the technical problems such as measurement result; Be inlaid with the line bank 2 with a plurality of bayonet sockets 21 in described housing 1, this line bank 2 fixes with housing 1, coil into and out of line respectively with line bank 1 on corresponding bayonet socket binding post be electrically connected to, line bank 2 at housing 1 surface inserting band bayonet socket 21, like this when connecting wire, wire can directly insert in bayonet socket 21, utilize bayonet socket 21 binding post that wire and line bank 2 is interior of line bank 2 to be electrically connected to, so not only facilitate wiring, improve the wiring operating efficiency, simultaneously, also can prevent from contacting between wire, guarantee the normal detection of instrument and meter.

In the present embodiment, production for ease of line bank is installed, described line bank 2 is provided with plural screw, and is fixedly connected with housing 1 by screw 22, on line bank 2, fixing threaded hole is set, and utilize screw 22 that line bank 2 and housing 1 are fixed, so not only the production and assembly of line bank 2 be can be convenient to, simultaneously, line bank 2 and bonding strength housing 1 also can be guaranteed, prevent that effectively line bank 2 is loosening, affect the serviceability of current transformer; Certainly, also can not adopt screw mode link row 2, such as directly adopting hook mode that line bank 2 is connected with housing 1 buckle, can reach identical purpose equally, but adopt this mode to be easy to production and assembly, therefore, the execution mode of the present embodiment is preferred implementation.

Above-described embodiment should not be considered as restriction of the present utility model, but any improvement of doing based on spirit of the present utility model, all should be within protection range of the present utility model.

Claims

1. current transformer, include housing and be placed in the interior coil of housing, it is characterized in that being inlaid with the line bank with a plurality of bayonet sockets in described housing, this line bank and housing fix, coil into and out of line respectively with line bank on corresponding bayonet socket binding post be electrically connected to.

2. a kind of current transformer according to claim 1, is characterized in that described line bank is provided with plural screw, and be fixedly connected with housing by screw.
