Abstract

A terminal fitting (10) has a rectangular tube (13) with opposed first and second side plates (15, 16). A upper plate (17) is bent from the first side plate (15) into contact with the second side plate (16). A standing portion (23) stands up from the second side plate (16) and a pressing portion (25) is bent from the standing portion (23) and placed on the outer surface of the upper plate (17) to prevent the upper plate (17) from lifting. The pressing portion (25) is formed within a projecting range of the standing portion (23) to improve a yield of a punching operation from a metal plate.

Claims

1. A terminal fitting, comprising:

a tube with a bottom plate, first and second side plates bent from opposite sides of the bottom plate, a ceiling plate bent from a part of the first side plate spaced from the bottom plate and extending into connection with a connected portion of the second side plate, the ceiling plate having an outer surface;

at least one standing portion extending unitarily from the second side plate and standing more outward than the connected portion of the second side plate with the ceiling plate, the standing portion and the second side plate lying substantially in a common plane; and

at least one pressing portion cut from an intermediate area of the second side plate and bent unitarily up and in from the standing portion for contacting the outer surface of the ceiling plate, the pressing portion extending substantially perpendicularly from the plane in which the standing portion and the second side plate lie.

2. The terminal fitting of claim 1, further comprising a detecting portion bent in from a distal end of the standing portion and disposed for contact by a probe for testing electrical connection of the terminal fitting.

3. The terminal fitting of claim 1, wherein at least one lift preventing portion is provided at least at a front part or at a rear part of the standing portion for preventing a lift of the ceiling plate.

9. The terminal fitting of claim 1, further comprising a resilient contact in the tube for contacting a mating terminal fitting, and at least one auxiliary resilient piece disposed on the tube portion for contacting the resilient contact when the resilient contact is deformed by the mating terminal fitting, whereby the auxiliary resilient piece improves rigidity of the resilient contact.

10. The terminal fitting of claim 1, further comprising a bend between the pressing portion and the standing portion, the bend having a convex surface, the pressing portion having a pressing surface contacting the outer surface of the ceiling plate, the pressing surface extending continuously from the convex surface of the bend.

11. The terminal fitting of claim 10, wherein the bend lies substantially in plane defined by the second side plate.

12. The terminal fitting of claim 1, wherein the terminal fitting is formed from a unitarily piece of metal having opposite first and second surfaces, the first surface including the outer surface of the ceiling plate and a surface of the pressing portion that contacts the outer surface of the ceiling plate.

4. A terminal fitting comprising:

a tube with first and second side plates, a ceiling plate bent from the first side plate into connection with a connected portion of the second side plate, the ceiling plate having an outer surface;

at least one standing portion standing more outward than the connected portion of the second side plate with the ceiling plate;

at least one pressing portion cut from an intermediate area on at least one of the second side plate and the standing portion, the pressing portion being bent up and towards the first side plate and contacting the outer surface of the ceiling plate; and

at least one lift preventing portion provided at least at a front part or at a rear part of the standing portion for preventing a lift of the ceiling plate, wherein the lift preventing portion is formed with at least one recess at an edge of the second side plate, at least one projecting piece at an end edge of the ceiling plate, the projecting piece being deformed and driven into connection with side walls of the recess.

6. The terminal fitting of claim 4, further comprising a chamfered surface at a lateral edge of a leading end of the pressing portion near the ceiling plate for avoiding interference with the ceiling plate upon assembling the tube.

7. The terminal fitting of claim 4, further comprising a chamfered surface at a lateral edge of a leading end of the ceiling plate to be held in contact with the pressing portion for avoiding interference with the pressing portion upon assembling the tube.

8. The terminal fitting of claim 4, further comprising a chamfered surface at a lateral edge of a leading end of the pressing portion near the ceiling plate and a chamfered surface at a lateral edge of a leading end of the ceiling plate to be held in contact with the pressing portion for avoiding mutual interference between the pressing portion and the ceiling plate upon assembling the tube.

5. A terminal fitting comprising:

a tube with first and second side plates, a ceiling plate bent from the first side plate into connection with a connected portion of the second side plate, the ceiling plate having an outer surface;

at least one standing portion standing more outward than the connected portion of the second side plate with the ceiling plate; and

at least one pressing portion cut and bent from the standing portion and contacting the outer surface of the ceiling plate, an escaping recess being formed at a leading edge of the standing portion for preventing interference with the pressing portion.
