Terminal box for electrical connections

Abstract

Electrical connection terminal unit comprising a box (100;1000) provided inside with a block (110;1110) for housing at least one pair of electrical connectors (200;1200) comprising at least one element (211,212;1211,1212) for retaining the end of the wires (1a,1b) of a cable (1) and at least one flat contact pin (211c,212c;1211c,1212c) of the ''fast-on'' type, said block (110;1110) comprising at least two seats (111,112;1211,1212) of suitable depth in the vertical direction (Z-Z) suitable for housing said elements (211,212;1211,1212) for retaining the wires (1a,1b) of the cable (1) and extending perpendicularly towards the outside of the bottom (100b;1100b) of the box (100; 1100) so as to form a housing (114;1114) for the contact pins (211c,212c;1211c,1212c), said retaining elements (211;212) being of the spring type and arranged parallel to the bottom (101b;1101b) of the box (100;1100) of the terminal unit.

Description

technical field [0001] The invention relates to a junction box for connecting cables. Background technique [0002] It is well known in the technical field related to cable assemblies that there are difficulties in the connection required to keep the cables firmly fixed when the cables have been connected to connection / branch terminal units mounted on various electronic devices, home appliances, and the like. [0003] These difficulties are mainly due to the presence of screws for clamping the ends of the wires, which, in addition to forming an extra part of the unit, has an associated cost which has to be installed during a subsequent production step and which significantly increases labor costs. [0004] In addition to this, the screws need to be screwed in to determine the intended insertion direction of the wires, and tend to become loose due to vibrations from household appliances, causing wire contacts to become less reliable over time.

AI Technical Summary

Problems solved by technology

[0002] It is well known in the technical field related to cable assemblies that there are difficulties in the connection required to keep the cable firmly fixed when the cable has been connected to a connection / branch terminal unit mounted on various electronic devices, home appliances, etc.

[0003] These difficulties are mainly due to the presence of screws for clamping the ends of the wires, which, in addition to forming an extra part of the unit, has an associated cost which has to be installed during a subsequent production step and adds significantly to labor costs

[0004] In addition to this, screws need to be screwed in to orient the intended insertion of the wire and tend to become loose from vibrations from the appliance, making wire contact less reliable over time

[0005] In addition to this, terminal units of the known type, especially with small dimensions, have outputs of the electrical connection to the device which are misaligned and not arranged in the same plane, resulting in the need to produce connectors which connect can not be standardized, has obvious difficulties in availability, and increases warehouse inventory and management costs
