Description

Technical Field

[0001] The utility model relates to the technical field of current transformers, in particular to a current transformer convenient for wiring. Background Technique

[0002] A current transformer is a measuring and protecting device used in a power system. Its main function is to convert high current into low current for the use of measuring instruments and protection devices. It plays a key role in the power system and can ensure the safety and stability of the system.

[0003] During the use of current transformers at the present stage, wiring is usually required at the P1 and P2 terminals to ensure the normal operation of the equipment. However, the currently commonly used power connection method is to connect through screws. This connection method has some obvious disadvantages. First, screw connection is prone to the problem of thread slipping, affecting the stability and safety of wiring. Second, in some smaller electrical boxes, especially when a current transformer needs to be installed, it is difficult to operate a screwdriver, and the problem of insufficient space is more prominent. This not only increases the installation difficulty but also may affect the normal use and maintenance of the current transformer.

[0004] In view of the above problems, we have developed a current transformer convenient for wiring. Content of the Utility Model

[0007] A current transformer convenient for wiring includes a transformer body. Three sliding grooves are opened on both sides of the transformer body, two of which are opened on one side, and the other is opened on the other side and located between the corresponding two sliding grooves. The inside of each sliding groove is slidably connected with a sliding rod. One end of each sliding rod and inside the sliding groove is fixedly connected with a sliding plate. Springs are sleeved on the outside of each sliding rod and between the sliding plate and the sliding groove. Grooves are opened on both sides of the transformer body. One end of each sliding rod is fixedly connected with a connecting plate. A pull rod is fixedly connected to the outside of each connecting plate. One end of each pull rod extends into the groove and is fixedly connected with a fixing plate. Anti-slip tooth structures are arranged on the inner sides of the fixing plates.

[0008] By pulling the sliding rod with the pull rod, the sliding rod will drive the sliding plate to move when moving. The sliding plate moves, thus compressing the spring. Then, the connecting wire is placed in the groove, and the fixing plate will rebound under the action of the spring, thereby clamping the terminal on the connecting wire to fix it.

[0009] In a preferred embodiment, positioning protrusions for cooperating with the power connection terminals are provided inside the groove.

[0010] The power connection terminals can be sleeved on the positioning protrusions to fix the power connection terminals.

[0011] In a preferred embodiment, a mounting plate is fixedly connected to the bottom of the current transformer body, and two fixing holes are symmetrically formed inside the mounting plate.

[0012] By providing the fixing holes, the mounting plate and the current transformer body can be fixedly installed.

[0013] In a preferred embodiment, limiting grooves are equidistantly formed on the current transformer body, and adjusting holes are symmetrically and equidistantly formed on both sides of the current transformer body.

[0014] The limiting grooves are used for winding cables.

[0015] In a preferred embodiment, a protective sleeve is provided on the outer side of the current transformer body, and the protective sleeve is arranged in an arc shape.

[0016] The protective sleeve can protect the wound cables.

[0017] In a preferred embodiment, mounting rods are symmetrically and fixedly connected to the bottom of the protective sleeve, and the mounting rods are respectively connected to the corresponding adjusting holes by screws.

[0018] Connect the mounting rods to the adjusting holes by screws. If the cables are larger or smaller, the position between the mounting rods and the adjusting holes can be adjusted.

[0019] The current transformer for facilitating wiring provided by the present utility model has the following advantages:

[0020] By pulling the pull rod, the sliding rod moves, driving the sliding plate to squeeze the spring. Then, place the connecting wire into the groove, sleeve the power connection terminal on the positioning protrusion, and the fixing plate rebounds under the action of the spring to clamp the terminal and fix the connecting wire. Connect the mounting rod to the adjusting hole by a screw, adjust the position to adapt to cables of different sizes, and the protective sleeve protects the wound cables. Through this design, the cables can be quickly connected, the problem of screw thread slipping can be avoided, and a screwdriver is not required in a narrow space, solving the problem of insufficient space.
