Marking type plastic junction box

Abstract

The invention discloses a marking type plastic junction box and belongs to the technical field of circuit connection fittings. The marking type plastic junction box comprises a base, an upper cover, awire clamping terminal, a wire pressing block and a plastic hinge connecting the upper cover with the base, wherein the base is a shell with an opening in the upper surface; the upper cover is a shell with an opening in the lower surface; the upper cover can be buckled on the base around the plastic hinge; the wire pressing block is arranged in the upper cover; the wire clamping terminal is arranged in the base; when the base and the upper cover are fastened, the wire pressing block of the upper cover is pressed into a wire clamping terminal gap in the base, and a wire is pressed into a wireclamping terminal slot to realize electric connection; the base and the upper cover are both subjected to integrated injection moulding by using the plastic added with laser powder, and identificationinformation is directly etched by laser on the surface of the upper cover or the bottom surface of the base; the marking type plastic junction box disclosed by the invention overcomes the problems ofcomplicated connection operation, poor reliability, low automation degree of identification information marking and reading, low reading identification rate and the like in existing junction box, andcan be applied to quick connection of electric appliance networks such as electronic detonators, electric detonators and light emitting diodes.

Description

technical field [0001] The invention belongs to the technical field of circuit connection accessories, and in particular relates to a markable plastic junction box. Background technique [0002] In practical application now, the electronic detonator can control the detonation process through the electronic control module. Among them, the accuracy, reliability and stability of the connection between the foot wire of the electronic detonator and the output bus of the initiator are important factors affecting the reliability of the electronic detonator network. In order to realize the reliable connection of the electronic detonator foot wire and the detonating bus bar, the prior art provides different forms of junction boxes, such as: "a junction box" disclosed in the Chinese patent literature with the publication number CN203504092U and the Chinese patent document with the publication number CN203218461U The "quick wire clamp and its crimping structure" disclosed in the paten...
