Abstract

A terminal module includes: a conductive terminal to be contacted and cooperated with a mating terminal, the conductive terminal including a base and a mating end at a front of the base, the mating end including a contact portion to be contacted and cooperated with the mating terminal and a front end portion at a front end of the contact portion; and a plastic part, wherein the plastic part is arranged at the front end portion so that a gap between the contact portion of the conductive terminal and the mating terminal is less than 0.1 mm after cooperated.

First claim

What is claimed is:

1. A terminal module comprising:
a conductive terminal to be contacted and cooperated with a mating terminal, the conductive terminal including:
a base; and
a mating end at a front of the base, the mating end including:
a contact portion to be contacted and cooperated with the mating terminal; and
a front end portion at a front end of the contact portion; and

a plastic part, wherein
the plastic part is arranged at the front end portion so that a gap between the contact portion of the conductive terminal and the mating terminal is less than 0.1 mm after the conductive terminal is mated to the mating terminal.

2. The terminal module as claimed in claim 1 , wherein the plastic part includes a guiding portion warped in a direction opposite to a cooperating direction.

3. The terminal module as claimed in claim 2 , wherein the plastic part is integrally formed on the front end portion.

4. The terminal module as claimed in claim 2 , wherein the plastic part is assembled on the front end of the contact portion.

5. The terminal module as claimed in claim 3 , wherein the front end portion is warped from the front end of the contact portion in a direction opposite to the cooperating direction.

6. A mating assembly comprising:
a terminal module including:
a plastic part; and
a conductive terminal including a base and a mating end at a front of the base, the mating end including:
a contact portion; and
a front end portion at a front end of the contact portion; and

a mating terminal module matched with the terminal module, the mating terminal module including a mating terminal to be contacted and cooperated with the conductive terminal, wherein
the plastic part is arranged at the front end portion, so that a gap defined between the contact portion of the conductive terminal and the mating terminal, is less than 0.1 mm after the conductive terminal is mated to the mating terminal.

7. The mating assembly as claimed in claim 6 , wherein the conductive terminal comprises an elastic terminal cooperating with the mating terminal by elastic abutment.

8. The mating assembly as claimed in claim 7 , wherein a size of the contact portion of the conductive terminal is at least twice a size of the front end portion.

9. The mating assembly as claimed in claim 8 , wherein the mating terminal includes a base and a mating end at the front of the base, the mating end of the conductive terminal and the mating end of the mating terminal have substantially same structure.

10. The mating assembly as claimed in claim 9 , wherein the mating terminal module includes a mating plastic part, the plastic part is integrally formed on the front end, and the mating plastic part is integrally formed on the front end of the mating terminal.

11. A terminal module comprising:
a conductive terminal to be contacted and cooperated with a mating terminal, the conductive terminal including:
a base; and
a mating end at a front of the base, the mating end including:
a contact portion to be contacted and cooperated with the mating terminal;
a front end portion located at a front end of the contact portion and defining a rectangular cross-section with two long sides and two short sides perpendicular to each other wherein the long side defines a main surface and the short side defines a side edge surface of the front end portion; and
a plastic part, wherein
the plastic part is arranged at the front end portion and forms a step structure to cover only a front region of one main surface and an end face of the front end portion.

12. The terminal module as claimed in claim 11 , wherein the plastic part does not cover the side edge surfaces.

13. The terminal module as claimed in claim 11 , wherein the plastic part forms a wedge configuration in a side view.

14. The terminal module as claimed in claim 13 , wherein the plastic part includes a guiding portion with a curved surface compliantly connecting to the other main surface.

15. The terminal module as claimed in claim 14 , wherein the plastic part includes a flat face opposite to the curved surface.

16. The terminal module as claimed in claim 11 , wherein the front end portion defines a first thickness along a thickness direction thereof, the plastic part defines a second thickness along said thickness direction, and said second thickness is more than three times of the first thickness.
