Abstract

A single element wire to board connector terminal for clamping a conductor, includes: a base, side plates and hanging elastic arms. A hollow passage is formed on the base, for allowing the conductor to pass through the hollow passage. The side plates are bent and provided on two opposite sides of a front part of the base. The hanging elastic arms are extended backwardly and inwardly from the side plates respectively. An elastic arm restricting portion is extended from one of the hanging elastic arms and bent transversely, for protecting the elastic arm and providing access for the conductor. A conductor positioning portion is provided on a rear part of the base.

First claim

What is claimed is:

1. A single element wire to board connector terminal for clamping a conductor, including:
a base formed with a hollow passage thereon for allowing the conductor to pass through the hollow passage;
two side plates bent and provided on two opposite sides of a front part of the base; and
a first and a second hanging elastic arms and a conductor positioning portion, wherein the first and the second hanging elastic arms are extended backwardly and inwardly from the two side plates respectively, a first elastic arm restricting portion is extended from the first hanging elastic arm and bent transversely towards, above and beyond the second hanging elastic arm, and the conductor positioning portion is provided on a rear part of the base.

2. The single element wire to board connector terminal according to claim 1 , wherein the first elastic arm restricting portion is formed with a tongue extended backwardly and downwardly.

3. The single element wire to board connector terminal according to claim 1 , wherein each of the first and the second hanging elastic arms is formed with a clamping portion for clamping the conductor, and a stop portion extended forwardly and upwardly from the clamping portion.

4. The single element wire to board connector terminal according to claim 1 , wherein the two side plates have different lengths along the base longitudinally, and the first and the second hanging elastic arms have different lengths along the base longitudinally.

5. The single element wire to board connector terminal according to claim 1 , wherein the two side plates are bent at upper ends thereof to form a convex portion and a concave portion respectively, and the convex portion is engaged with the concave portion to form a top plate connecting the two side plates.

6. The single element wire to board connector terminal according to claim 1 , wherein one of the two side plates is formed with a welding portion.

7. The single element wire to board connector terminal according to claim 1 , wherein the second hanging elastic arm is formed with a second elastic arm restricting portion bent transversely towards, above and beyond the first hanging elastic arm, so when the conductor passes through the hollow passage and pushes on the first and the second hanging elastic arms, the first and the second hanging elastic arms are respectively and independently deformed outwards.

8. The single element wire to board connector terminal according to claim 7 , wherein the first and the second hanging elastic arms is formed with a clamping portion for clamping the conductor, and a stop portion extended forwardly and upwardly from the clamping portion.

9. The single element wire to board connector terminal according to claim 1 , wherein the first elastic arm restricting portion is further extended and bent downwardly to form an inverted U shape, and the first elastic arm restricting portion has a fixed end in conjunction with the first hanging elastic arm and a free end opposite to the fixed end, the free end having a pressing portion.

10. The single element wire to board connector terminal according to claim 9 , wherein the pressing portion has a warping structure for sustaining a pressing force applied on the pressing portion so as to allow deformation of the first hanging elastic arm in conjunction with the first elastic arm restricting portion to be controlled.

11. A single element wire to board connector terminal for clamping a conductor, including:
a base formed with a hollow passage thereon for allowing the conductor to pass through the hollow passage;
two side plates bent and provided on two opposite sides of a front part of the base; and
two hanging elastic arms, an elastic arm restricting portion and a conductor positioning portion, wherein the two hanging elastic arms are extended backwardly and inwardly from the two side plates respectively, the elastic arm restricting portion is extended from one of the two hanging elastic arms and bent transversely, and the conductor positioning portion is provided on a rear part of the base,
wherein the base has a middle part protruded upwardly and is formed with a welding portion at each of the front and rear parts thereof, and an elastic arm positioning portion is provided on the base and between the two hanging elastic arms.

12. The single element wire to board connector terminal according to claim 11 , wherein the elastic arm positioning portion is provided at a position deviated from a central line of the base.

13. A single element wire to board connector terminal for clamping a conductor, including:
a base formed with a hollow passage thereon for allowing the conductor to pass through the hollow passage;
two side plates bent and provided on two opposite sides of a front part of the base; and
two hanging elastic arms, an elastic arm restricting portion and a conductor positioning portion, wherein the two hanging elastic arms are extended backwardly and inwardly from the two side plates respectively, the elastic arm restricting portion is extended from one of the two hanging elastic arms and bent transversely, and the conductor positioning portion is provided on a rear part of the base,
wherein the conductor positioning portion is connected to the base, and includes a conductor stop surface vertical to the base and three stop plates extended from left, right and top sides of the conductor stop surface so as to form a box-like structure for preventing the conductor from escape.
