Problems solved by technology

The existing through-wall terminal block adopts two combined technologies: one is to open a through hole on each terminal block, and then use a longer bolt to pass through the hole to connect multiple terminal blocks into one , and finally fix it with nuts at the tail, because in actual use, the combination length of the through-wall terminal block is diverse, and there are many length specifications, resulting in too many bolt specifications, increased processing difficulty, and high manufacturing and management costs. Improvement; another combination technology is to directly

Abstract

The invention discloses a wall-through connection terminal board comprising a front end plate (1), a rear end plate (2) and a plurality of connection terminal blocks (3). The front faces of the front end plate (1) and each connection terminal block (3) are provided with raised L-shaped hooks (A); the back faces of the rear end plate 92) and each connection terminal block (3) are provided with connecting holes (H) corresponding to the hooks (A); one side wall of each connecting hole (H) is provided with a hanging platform (B) matched with each hook (A); and the front end plate or the hook (A) of a former connection terminal block can be buckled on the hanging platform (B) of the next connection terminal block or the rear end plate. By adopting the buckling mode, the connection terminal blocks (3) can be combined and spliced to achieve any length without being limited by the amount so that the wall-through connection terminal board can flexibly realize any length and is convenient to use. Meanwhile, the wall-through connecting terminal board is also provided with a protection cover (6) which can prevent dust and foreign matters from intruding and improve the security of the wall-through connecting terminal board.

Description

technical field [0001] The invention relates to a low-voltage switchgear, control equipment and auxiliary electrical appliances for relay protection equipment, in particular to a through-wall terminal block used in the field of relay protection. Background technique [0002] In the fields of low-voltage electrical appliances, relay protection industry and industrial automation, the through-wall terminal block installed on the electrical control cabinet and relay protection screen panel has been more and more widely used because of its convenient wiring and reliable performance. The application of this kind of products is composed of multiple terminal blocks into a whole. It is necessary to determine the number of terminal blocks first, and then connect the multiple terminal blocks into one body through various combination techniques to facilitate installation into the cabinet. or on the panel of the housing. The existing through-wall terminal block adopts two combined techn...
