Description

Technical Field

[0001] The utility model relates to the technical field of wiring terminals, in particular to a wiring terminal which is easy to assemble and disassemble. Background Art

[0002] The terminal block is used to facilitate the connection of wires. It is actually a piece of metal sealed in insulating plastic. There are holes at both ends for inserting wires and screws for tightening or loosening. For example, two wires sometimes need to be connected and sometimes need to be disconnected. At this time, they can be connected with terminals and can be disconnected at any time without welding them or twisting them together.

[0003] For example, a utility model with authorization announcement number CN218123741U discloses a terminal block that is easy to disassemble and assemble, and the device includes a mounting shell, and fixing plates are fixedly connected to both sides of the interior of the mounting shell, and a limiting groove is arranged through the middle of the fixing plate, and grooves are arranged through both ends of the mounting shell, and the grooves are also arranged inwardly through the limiting grooves, and a terminal body is correspondingly arranged inside the mounting shell, and connecting blocks are fixedly connected to both ends of the terminal body, and the connecting blocks correspond to the limiting grooves, and a base is fixedly connected to the bottom inner side of the mounting shell, and the fixing plate and the limiting groove can correspond to the connecting blocks at both ends of the terminal body, and then the terminal body can be clamped in the interior of the mounting shell through the grooves and the protrusions, so that when the terminal body is connected to the sub-base, it can be more tightly pressed against each other, and it is more stable during installation and will not easily loosen.

[0004] When the device is in use, the connecting block corresponds to the internal limiting groove. When the protrusion slides to the position of the groove, it can pop outward under the action of the first spring, thereby realizing the installation of the terminal body. However, the first spring has a certain deformation ability and is prone to deformation during long-term use, thereby affecting the stability of the terminal body when it is installed and fixed inside the mounting shell. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art, the utility model provides a terminal block that is easy to assemble and disassemble, which can solve the technical problem that the first spring has a certain deformation ability and is prone to deformation during long-term use, thereby affecting the stability of the terminal block body when it is installed and fixed inside the mounting shell.

[0006] In order to solve the above technical problems, the utility model provides the following technical solutions: a terminal block that is easy to assemble and disassemble, comprising a mounting shell, a mounting seat symmetrically arranged on both side walls of the mounting shell, a bidirectional threaded screw rod connected to the two mounting seats for limited rotation, two sliders symmetrically sleeved on the outer sides of the two bidirectional threaded screw rods, two connecting grooves symmetrically arranged on the inner side wall of the mounting shell, a connecting plate limitedly slidingly arranged in the two connecting grooves, an arm hingedly connected between the surface of the connecting plate and the surface close to the mounting seat and the surfaces of the two sliders, a rubber gasket arranged on the other surface of the two connecting plates, and a terminal body arranged in the mounting shell and between the two connecting plates.

[0007] As a preferred technical solution of the utility model, a cover plate is provided on the top of the mounting shell, a stabilizing block is provided at the bottom of the cover plate and located inside the mounting shell to contact the top of the terminal body, and two sockets are symmetrically provided on both sides of the stabilizing block.

[0008] As a preferred technical solution of the utility model, a connecting block is connected to the top of each of the two connecting plates, and two insert rods are symmetrically arranged on the surfaces of the two connecting blocks.

[0009] As a preferred technical solution of the utility model, two insertion rods symmetrically arranged on the surface of the connecting block are plug-connected with the insertion holes provided on the side wall of the stabilizing block.

[0010] As a preferred technical solution of the utility model, the top end of the bidirectional threaded screw rod is movably passed through the top wall of the mounting seat and is connected to an adjusting knob for rotating and adjusting the bidirectional threaded screw rod.

[0011] As a preferred technical solution of the utility model, the front surface of the terminal body is provided with a plurality of wiring through holes, the top of the terminal body is provided with screw holes connected to the wiring through holes, and the front surface of the mounting shell is provided with square through holes corresponding to the wiring through holes.

[0012] Compared with the prior art, the utility model can achieve the following beneficial effects:

[0013] 1. The two sliders are adjusted to move relative to each other by the cooperation of the two bidirectional threaded screw and the two sliders. The two sliders that move relative to each other and the arm are arranged so that the connecting plate moves relative to the side wall of the terminal body arranged in the mounting shell, thereby limiting and fixing the terminal body arranged in the mounting shell. The friction between the connecting plate and the side wall of the terminal body can be increased by the cooperation of the connecting plate and the rubber gasket, thereby improving the stability of the terminal body. The arrangement of this structure can stably realize the installation and fixation of the terminal body or quickly disassemble the terminal body.

[0014] 2. At the same time, through the fixed connection between the connecting plate and the connecting block, the connecting block is moved and adjusted toward the stabilizing block fixedly arranged on the bottom wall of the cover plate. The two plug rods arranged on the surface of the connecting block are inserted into the two plug holes opened on the side wall of the stabilizing block, thereby realizing the limiting fixation of the stabilizing block and the cover plate, so that the terminal body can be limited and fixed at the same time as the cover plate covered to the top of the mounting shell is limited and fixed, thereby improving the practicality of the device.

A rubber gasket 7 is arranged on the other surface of the two connecting plates 6. Finally, a terminal body 15 is arranged in the mounting shell 1 and between the two connecting plates 6.

[0023] When the terminal body 15 set in the installation shell 1 is limited and fixed, the bidirectional threaded screw 3 is first adjusted and rotated by the adjusting button 14, and then the two sliding blocks 4 are driven to approach each other by the rotation of the adjusted bidirectional threaded screw 3, and then the two sliding blocks 4 approaching each other are matched with the two arm rods 5 to realize the pushing of the connecting plate 6, and the connecting plate 6 is set to move toward the side wall of the terminal body 15 and the terminal body 15 is limited and fixed.
