Description

Technical Field

[0001] This utility model relates to the field of terminal block technology, and more specifically to a terminal block with a protective structure. Background Technology

[0002] Traditional terminal block products require maintaining the stability of the wiring after connection to prevent the wires from easily coming loose under external pulling force. Although terminal blocks achieve the anti-detachment function, locking the wires requires multiple steps, making the operation cumbersome and inconvenient for quick wire removal afterwards. When the terminal blocks are not connected to the wiring for a long time, dust will remain inside. Therefore, there is a lack of a structure for cleaning the internal channels of the terminal blocks during wiring. Utility Model Content

[0003] In summary, to overcome the shortcomings of the prior art, this utility model provides a terminal block with a protective structure.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a terminal block with a protective structure, comprising a base and a protective cover. The base is provided with a wiring groove, which is divided into several wiring cavities by a partition. A terminal block assembly is provided in each wiring cavity. Mounting seats are symmetrically arranged on both sides of the wiring groove. Each mounting seat includes a connecting part perpendicularly connected to the base and a positioning part parallel to the base. An installation gap is provided between the positioning part and the top of the wiring groove for inserting the protective cover. The protective cover includes a top cover part inserted into the installation gap and a limiting part abutting against the side wall of the wiring groove. The spacing of the installation gap is adapted to the thickness of the top cover part.

[0005] By adopting the above technical solution, the protective cover serves to protect the wiring terminals and prevent dust. The protective cover and the base are connected by a plug-in joint, which facilitates quick and easy disassembly and assembly. The structure is simple and highly stable.

The elastic locking part abuts against the spacer, and the first wiring segment is connected to the screw assembly. This double positioning prevents the terminal piece from moving and improves stability.

[0008] The present invention further comprises: the double-layer terminal piece is composed of a first terminal piece and a second terminal piece arranged vertically; the first wiring segment of the first terminal piece is attached to the first wiring segment of the second terminal piece; the second wiring segment of the first terminal piece is arranged vertically at a distance from the second wiring segment of the second terminal piece; the elastic locking part is disposed on the connecting segment of the first terminal piece; the elastic locking part includes a connecting end connected to the first wiring segment of the first terminal piece and a movable end that is oscillating; the connecting segment of the second terminal piece is provided with a movable through hole corresponding to the position of the elastic locking part, allowing the movable end of the elastic locking part to move up and down.

[0009] By adopting the above technical solution, the structure is simple and easy to install quickly, while the elastic card part has a larger range of motion, stronger elasticity, and stronger limiting effect.

[0010] The present invention further includes: the partition block includes a mounting cavity with an opening at the lower end, the mounting cavity being connected to the mounting channel; when the first wiring segment of the double-layer terminal piece is inserted into the first assembly cavity from the second assembly cavity through the mounting channel, the first wiring hole and the mounting hole overlap; and the movable end of the elastic locking part is locked in the mounting cavity.

[0011] By adopting the above technical solution, compared with the elastic card part directly abutting against the spacer, the use of the mounting cavity further enhances the effect of the limiting connection, strengthens the stability of the connection, and saves materials.

[0012] The present invention further features that the protective cover is made of a transparent material.

[0013] By adopting the above technical solution, it is convenient to observe the wiring situation.

[0014] The present invention further includes the following features: the length of the top cover is greater than the distance between the two mounting bases, and positioning slots adapted to the positioning part are respectively provided on both sides of the top cover.

[0015] By adopting the above technical solution, the protective cover and the base are snapped together to prevent the protective cover from detaching, thus improving stability.

[0016] The present invention is further provided that the mounting base is integrally formed with the base or can be detachably connected by a connector.

[0017] By adopting the above technical solution, the mounting base and the base are integrally formed, which facilitates quick assembly, or the mounting base and the base are separately set and can be detachably connected by connectors, which facilitates processing and has high stability.
