Description

Technical Field

[0001] This utility model relates to the field of electrical technology, specifically to a terminal block. Background Technology

[0002] Terminal blocks are insulating components that support multiple or more sets of mutually insulated terminal assemblies and are used for fixing and supporting parts. The function of terminal blocks is to connect the wiring of equipment inside and outside the panel, facilitating signal (current and voltage) transmission. Terminal blocks make wiring neater, easier to maintain, and provide reliable connections between long-distance lines, simplifying construction and maintenance. However, existing cables are connected to terminal blocks via copper plates, resulting in insufficient creepage distance between the terminals, reducing the safety factor. Furthermore, the leads of the current transformer are led out relative to the cable direction, making wiring inconvenient. Utility Model Content

[0014] The present invention is further provided that a clearance groove is provided on the inner side of the junction between the baffle and the protective cover.

[0015] In the above structure, the recessed groove provides sufficient elastic space when the dovetail groove engages with the locking block, which facilitates the installation and removal of the protective cover and improves the stability of the protective cover installation.

[0016] The present invention is further configured such that the first side cover and the second side cover are provided with receiving grooves on the side facing the base, and the base is provided with a through opening for the current transformer to pass through at the position corresponding to the receiving groove, and the receiving groove and the through opening cooperate to form the receiving cavity.
