Description

Technical Field

[0001] This utility model relates to a single-pole terminal block that is easy to wire, and belongs to the field of terminal block technology. Background Technology

[0002] With the development of the electronics industry, terminal blocks, as accessories for achieving electrical connections, are increasingly widely used and diverse. Generally, terminal blocks consist of an insulating housing and a metal connector inside the housing. Single-pole terminal blocks, however, employ a modular design, allowing for quick assembly and replacement according to different application needs, improving installation and maintenance convenience. However, traditional single-pole terminal blocks still rely on bolts for secure wiring, requiring tools and proving extremely inconvenient. Therefore, this invention proposes a single-pole terminal block that facilitates wiring. Utility Model Content

[0003] Based on the above background, the purpose of this utility model is to provide a single-pole terminal block that is easy to wire, thereby solving the problems in the background art.

[0004] This utility model provides the following technical solution:

[0005] A single-pole terminal block for easy wiring includes a housing. The top of the housing has a groove with an opening on the right side. Several through-holes are formed on the right end face of the housing. A set of limiting grooves is formed on the top of the housing, communicating with the groove. Ear plates are fixedly connected to the limiting grooves by bolts. A mounting plate is provided between the ear plates. Several first through-holes are formed on the top of the mounting plate. A pressure post is movably disposed within each first through-hole. A limiting block is provided on the bottom plate of the pressure post. A connecting post is provided at the bottom of the limiting block. A locking block is provided at the bottom of the connecting post. A locking groove is formed on the right end face of the locking block, into which an elastic metal component is inserted. A cover plate for closing the opening is provided at the bottom left end of the mounting plate. A metal plate is provided at the bottom of the groove. Several limiting through-holes are formed on the cover plate. A limiting component is provided on the limiting block, capable of locking with the limiting through-holes. An elastic reset component is provided on the end face of the cover plate near the groove.

[0006] Preferably, the limiting component includes a mounting cavity, which is opened on the end face of the limiting block near the cover plate. A movable block is movably disposed in the mounting cavity. A locking block is provided on the left end face of the movable block. The locking block can be inserted into the limiting port for limiting. A sleeve post is provided in the center of the right end face of the movable block. A first spring is sleeved on the sleeve post. The right end of the first spring abuts against the inner wall of the mounting cavity.

[0007] Preferably, the elastic reset component includes an abutment plate, which is detachably and fixedly connected to the right end face of the cover plate. The abutment plate has several second through holes, which slide in conjunction with the connecting post. A second spring is sleeved on the connecting post, with one end of the second spring abutting against the top surface of the abutment plate and the other end of the second spring abutting against the bottom of the limiting block.

[0008] Preferably, the bottom sidewall of the opening is higher than the top surface of the metal plate.

[0009] Preferably, the locking block is made of insulating material.

[0010] Compared with the prior art, the present invention has the following advantages:

[0011] This utility model discloses a single-pole terminal block that facilitates wiring. By setting a pressure post, a limiting block, a connecting post, a locking block, and an elastic metal part, when wiring, the metal part of the wire is inserted into the through-hole, and then the pressure post is pressed into the groove, which drives the limiting block to move downward. In turn, the limiting block and the elastic metal part move upward simultaneously. The elastic metal part can press the metal part of the wire between the elastic metal part and the metal plate to conduct electricity, so that wiring does not require tools and is more convenient and faster.

[0012] This utility model provides a single-pole terminal block that facilitates wiring. By setting a limiting component, when the pressure post is fully pressed into the first through hole, the limiting block is pushed to the same horizontal plane as the limiting through hole. At this time, the locking block loses contact with the cover plate surface, the first spring elastically resets, and drives the movable block to move towards the cover plate end in the mounting cavity. The locking block is inserted into the limiting through hole, which can prevent the metal elastic element from rebounding and causing the wiring to be unstable.

[0013] This utility model provides a convenient single-pole terminal block for wiring. By setting an elastic reset component, during secondary wiring, the locking block in the limiting port is pushed out. The first spring compresses the movable block and moves it away from the cover plate in the mounting cavity. The locking block loses its limiting function. The second spring rebounds, which can drive the limiting block, pressure post, connecting post, locking block and elastic metal parts back to their original positions, so that wiring can be performed again, which is more convenient and faster.
