Abstract

A socket terminal ( 10 ) to be fitted and connected to a mating pin terminal ( 20 ) includes a tubular portion ( 11 ) to be fitted to the pin terminal ( 20 ). The tubular portion ( 11 ) includes a base portion ( 12 ) provided on a side opposite to a fitting starting end to the pin terminal ( 20 ) and a plurality of terminal pieces ( 13 ) extending in an axial direction of the tubular portion ( 11 ) from the base portion ( 12 ) toward the pin terminal ( 20 ), spaced apart in a circumferential direction of the tubular portion ( 11 ) and capable of resiliently coming into contact with the outer peripheral surface of the pin terminal ( 20 ) fitted in the tubular portion ( 11 ). The base portion ( 12 ) includes a plurality of terminal pieces ( 16 ) projecting toward the pin terminal ( 20 ) radially of the tubular portion ( 11 ) and configured to hold the outer peripheral surface of the pin terminal ( 20 ).

First claim

The invention claimed is:

1. A socket terminal including a tubular portion with opposite front and rear ends, the tubular portion being configured to be fit and connected to a mating pin terminal inserted into the tubular portion from the front end, the tubular portion comprising:
a base portion provided at the rear end of the tubular portion, the base portion having an inner circumferential surface;
a plurality of holding portions projecting radially inward from the inner circumferential surface of the base portion and configured to hold an outer peripheral surface of the pin terminal at a leading end thereof, the holding portions being resiliently deformable radially outward; and
a plurality of terminal pieces integral with the base portion and extending in an axial direction of the tubular portion from the base portion toward the front end, the terminal pieces being spaced apart in a circumferential direction of the tubular portion and capable of resiliently contacting the outer peripheral surface of the pin terminal fit in the tubular portion.

2. The socket terminal of 1 , wherein the holding portions are provided between adjacent ones of the terminal pieces of the base portion.

3. The socket terminal of claim 1 , wherein the pin terminal and the holding portions are in an electrically insulated state.

4. The socket terminal of claim 1 , wherein the holding portions are cut from areas of the base portion between opposite longitudinal ends of the base portion and are bent to project radially inward.

5. The socket terminal of claim 4 wherein the holding portions are bent about bend lines in that are substantially parallel to a longitudinal axis of the tubular portion.

6. The socket terminal of claim 4 wherein the holding portions are bent about bend lines in that are transverse to a longitudinal axis of the tubular portion.

7. The socket terminal of claim 1 , wherein the terminal pieces are cantilevered forward from the base portion.

8. A socket terminal including a tubular portion with opposite front and rear ends, the tubular portion being configured to be fit and connected to a mating pin terminal inserted into the tubular portion from the front end, the tubular portion comprising:
a base portion provided at the rear end of the tubular portion;
a plurality of terminal pieces integral with the base portion and extending in an axial direction of the tubular portion from the base portion toward the front end, the terminal pieces being spaced apart in a circumferential direction of the tubular portion and capable of resiliently contacting the outer peripheral surface of the pin terminal fit in the tubular portion; and
a plurality of holding portions projecting radially in from the base portion and configured to hold an outer peripheral surface of the pin terminal, the holding portions being resilient pieces that are resiliently deformable radially outward of the base portion, wherein
the pin terminal and the holding portions are in an electrically insulated state.

9. The socket terminal of claim 8 , wherein the plurality of holding portions are provided on a common circumference of an inner peripheral surface of the base portion.

10. The socket terminal of claim 8 , wherein the holding portions are cut from areas of the base portion between opposite longitudinal ends of the base portion and are bent to project radially inward.

11. The socket terminal of claim 10 wherein the holding portions are bent about bend lines in that are substantially parallel to a longitudinal axis of the tubular portion.

12. The socket terminal of claim 10 wherein the holding portions are bent about bend lines in that are transverse to a longitudinal axis of the tubular portion.

13. A socket terminal including a tubular portion with opposite front and rear ends, the tubular portion being configured to be fit and connected to a mating pin terminal inserted into the tubular portion from the front end, the tubular portion comprising:
a base portion provided at the rear end of the tubular portion;
a plurality of terminal pieces integral with the base portion and extending in an axial direction of the tubular portion from the base portion toward the front end, the terminal pieces being spaced apart in a circumferential direction of the tubular portion and capable of resiliently contacting the outer peripheral surface of the pin terminal fit in the tubular portion; and
a plurality of resiliently deformable holding portions cut from areas of the base portion between opposite longitudinal ends of the base portion and bent to project radially inward from the base portion while being resiliently deformable radially outward, the plurality of holding portions configured to hold an outer peripheral surface of the pin terminal.

14. The socket terminal of claim 13 , wherein the holding portions are cut from areas of the base portion between opposite longitudinal ends of the base portion and are bent to project radially inward.

15. The socket terminal of claim 14 , wherein the holding portions are bent about bend lines in that are substantially parallel to a longitudinal axis of the tubular portion.

16. The socket terminal of claim 14 , wherein the holding portions are bent about bend lines in that are transverse to a longitudinal axis of the tubular portion.
