Abstract

An improved wire connecting terminal structure extensively used in different electric appliances and equipments includes a wire connecting terminal in an input/output interface of the structure. The wire connecting terminal includes a plurality of metal contact brackets coupled with a plastic body by a plastic injection molding. The plastic body includes a two-sectional latch groove disposed on both left and right sides of the plastic body, so that a latch hook disposed on both left and right sides of the latching member is latched into an upper groove of the two-sectional latch groove, and a flexible multi-core cable is passed onto a metal contact bracket, and then the latching member is pressed and latched downward to latch the latch hook into a lower groove of the two-sectional latch groove, so as to closely contact the connecting wire with the metal contact bracket and constitute an overall wire connecting terminal.

Claims

1. An improved wire connecting terminal structure, comprising a plastic body, a plurality of metal contact brackets, a latching member and a multi-core cable;

wherein;

said plurality of metal contact brackets are arranged evenly and integrally formed with said plastic body by plastic injection molding and having a planar surface, said planar surface of an end portion of each of said plurality of metal contact brackets being exposed from the rear section of said plastic body;

said plastic body having an upper groove and a lower groove disposed on both a left side and a right side of said plastic body;

said latching member having a pair of latch hooks respectively disposed on a left side and a right side of said latching member, said pair of latch hooks of said latching member being initially latched into said upper groove disposed on both left and right sides of said plastic body, and said latching member includes a plurality of containing grooves corresponding to said plurality of metal contact brackets for respectively receiving conductors of said multi-core cable to contact corresponding metal contact brackets in said containing grooves, said latching member being pressed downward and latched by said pair of latch hooks of said latching member being latched into said lower groove disposed on both left and right sides of said plastic body to press each of said conductors of said multi-core cable in close contact with said planar surface of said end portion of said corresponding metal contact bracket to form an overall wire connecting terminal.

2. The improved wire connecting terminal structure of claim 1, wherein said end portion of each said metal contact bracket is bent back and said planar surface extends upwardly at an angle of inclination to provide a bias force against a corresponding conductor of said multi-core cable when said latch hooks are respectively latched into said lower grooves, said angle of inclination being reduced responsive to said pressing by said latching member.

3. An improved wire connecting terminal structure comprising a plastic body, a metal contact bracket, a latching member and a multi-core wire;

wherein;

a plurality of metal contact brackets are arranged evenly and integrally formed with said plastic body by plastic injection molding an end of each of said plurality of metal contact brackets being exposed from a rear section of said plastic body;

a two-sectional latch groove having an upper groove and a lower groove being disposed separately on both a left side and a right side of said plastic body;

said latching member having a pair of latch hooks respectively disposed on a left side and a right side of said latching member, and a plurality of containing grooves corresponding to said plurality of metal contact brackets said pair of latch hooks of said latching member being initially latched into said upper groove disposed on both left and right sides of said plastic body, and said latching member includes a plurality of containing grooves for separating said plurality of metal contact brackets one by one and passing a flexible multi-core cable onto said metal contact bracket in said containing groove and then said latching member being subsequently pressed and latched downward, so that said latch hook disposed on both left and right sides of said latching member is latched into said lower groove disposed on both left and right sides of said plastic body to keep said multi-core cable in a close contact with said metal contact bracket to form an overall wire connecting terminal, said metal contact bracket having an end being substantially S-shaped and bent upward twice with an angle of inclination.
