Abstract

A conductive component structure of wire connection terminal is manufactured at lower cost and more securely assembled with the conductive wire. The conductive component includes a main body in the form of a plate body and a restriction body connected on the main body. The restriction body defines a mouth section and has an oblique wall connected with the mouth section. When the conductive wire is plugged into the case into contact with the conductive component, the restriction body guides the conductive wire and the rear end of the conductive wire is restricted and secured by the oblique wall. The conductive component improves the shortcomings of the conventional structure that the conductive wire is apt to deflect or swing due to external force to lead to unstable contact and insecurity and affect the electro-conductive efficiency.

First claim

What is claimed is:

1. A conductive component structure of wire connection terminal, comprising:
a main body made of an electro-conductive material in the form of a plate body; and
a restriction body integrally formed on the main body or assembled/disposed on the main body, the restriction body defining a mouth section and having an oblique wall connected with the mouth section, the oblique wall extending from the mouth section to form a securing section in combination with the main body, the securing section narrowing both horizontally and vertically from the mouth section to thereby guide and secure a conductive wire plugged into the wire connection terminal.

2. The conductive component structure of wire connection terminal as claimed in claim 1 , wherein the oblique wall of the restriction body includes two lateral oblique walls and an upper oblique wall, the two lateral oblique walls being connected with the mouth section and obliquely extending in a direction away from the mouth section to respectively form a free end, the free ends being gradually converged to get closer to each other to form a holding opening, the upper oblique wall being connected with the mouth section and obliquely extending in a direction away from the mouth section and toward the main body to form a rear end section, the restriction body having a hardness greater than a hardness of the main body, two end sections of the main body being formed with bent edges upward extending from the lateral sides of the main body, whereby the two end sections of the main body are formed as a structure with a U-shaped cross section.

3. The conductive component structure of wire connection terminal as claimed in claim 1 , wherein two end sections of the main body are formed with multiple channels, the oblique wall of the restriction body having a first section connected with the main body and a second section obliquely extending in a direction away from the main body, at least two sides of the second section being arched toward the main body to form two arched edges, the second section being thereby formed as a structure with a substantially C-shaped cross section to define the mouth section, a concave side of the second section substantially facing the main body.

4. The conductive component structure of wire connection terminal as claimed in claim 3 , wherein the main body and the restriction body are made of the same electro-conductive material and disposed in the case, the case being assembled with the metal leaf spring, the restriction body including two oblique walls, a base section being connected between the first sections of the two oblique walls, the base section being overlaid on the main body, whereby the first sections of the oblique walls can elastically securely press and restrict the conductive wire.

5. The conductive component structure of wire connection terminal as claimed in claim 4 , wherein the metal leaf spring includes a first leaf spring and a second leaf spring, each of the first and second leaf springs having a head section, a bight section connected with the head section and a tail section connected with the bight section, a length of the tail section of the first leaf spring being smaller than a length of the tail section of the second leaf spring, the tail sections of the first and second leaf springs being respectively formed with a bent section, a contained angle of the bent section of the tail section of the first leaf spring being equal to or different from a contained angle of the bent section of the tail section of the second leaf spring, the metal leaf spring being mounted on a stake of the case, the head section and the bight section of the first leaf spring being overlaid on the head section and the bight section of the second leaf spring, while the tail section of the first leaf spring being separated from the tail section of the second leaf spring, the tail section of the second leaf spring partially extending into the restriction body, the tail section of the first leaf spring and the tail section of the second leaf spring respectively forming a pressing point against the conductive wire, whereby the oblique wall of the restriction body cooperates with the first and second leaf springs to press and restrict the conductive wire.

6. The conductive component structure of wire connection terminal as claimed in claim 1 , wherein the restriction body is integrally formed on the main body, the oblique wall including two lateral oblique walls and an upper oblique wall, the two lateral oblique walls being upward bent from two lateral sides of the main body and protruding from the lateral sides of the main body, the two lateral oblique walls defining a geometrical configuration, top ends of the lateral oblique walls being oppositely bent toward each other to form brow sections, the brow sections, the lateral oblique walls and the main body together defining the mouth section, the two lateral oblique walls obliquely extending in a direction away from the mouth section to respectively form a free end, the free ends being gradually converged to get closer to each other to form a holding opening, the upper oblique wall having a rear end section and a subsidiary end section, the subsidiary end section being in contact with the brow sections, the rear end section obliquely extending in a direction away from the brow sections and toward the main body.

7. The conductive component structure of wire connection terminal as claimed in claim 6 , wherein the main body and the restriction body are made of the same electro-conductive material and disposed in the case, the case being assembled with the metal leaf spring, the conductive component having two restriction bodies, a base section being connected between the rear end sections of the upper oblique walls of the two restriction bodies, the base section being integrally formed on the main body and overlaid on the main body.

8. The conductive component structure of wire connection terminal as claimed in claim 7 , wherein the metal leaf spring includes a first leaf spring and a second leaf spring, each of the first and second leaf springs having a head section, a bight section connected with the head section and a tail section connected with the bight section, a length of the tail section of the first leaf spring being smaller than a length of the tail section of the second leaf spring, the tail sections of the first and second leaf springs being respectively formed with a bent section, a contained angle of the bent section of the tail section of the first leaf spring being equal to or different from a contained angle of the bent section of the tail section of the second leaf spring, the metal leaf spring being mounted on a stake of the case, the head section and the bight section of the first leaf spring being overlaid on the head section and the bight section of the second leaf spring, while the tail section of the first leaf spring being separated from the tail section of the second leaf spring, the tail section of the second leaf spring partially extending into the restriction body, the tail section of the first leaf spring and the tail section of the second leaf spring respectively forming a pressing point against the conductive wire, whereby the oblique wall of the restriction body cooperates with the first and second leaf springs to press and restrict the conductive wire.
