Abstract

A butting surface (21) of a first butting terminal fitting (20) held by a first terminal accommodating member (40) is formed in a curved-surface configuration protruding toward a second butting terminal fitting (30) side held by a second terminal accommodating member (50). A plurality of contact spring pieces (33a and 33b) of the second butting terminal fitting (30) which are butted against the butting surface (21) and resiliently deformed are flat plate type leaf springs arranged on the same plane.

Claims

1. A butting type connector comprising:

a first butting terminal fitting having a butting surface;

a second butting terminal fitting made of a metal plate and having a plurality of contact spring pieces which are resiliently deformed when the plurality of the contact spring pieces are butted against the butting surface so as to be electrically conducted and connected to the first butting terminal fitting;

a first terminal accommodating member which holds the first butting terminal fitting so that the butting surface is exposed; and

a second terminal accommodating member which holds the second butting terminal fitting so that the plurality of the contact spring pieces are butted against the butting surface when the second terminal accommodating member is butted against the first terminal accommodating member,

wherein the butting surface is formed in a curved-surface configuration protruding to the second butting terminal fitting side,

wherein the plurality of the contact spring pieces are a plurality of flat plate type leaf spring pieces.

2. The butting type connector according to claim 1, wherein the butting surface is an outer peripheral surface of a semi-cylindrical raised structure whose cross-sectional form is a circular arc surface,

wherein the plurality of the contact spring pieces are flat plate type leaf springs which extend in the orthogonal direction to a generatrix of the butting surface, and

wherein the plurality of the contact spring pieces are arranged in a configuration of comb teeth at regular intervals to a direction of the generatrix of the butting surface.

3. The butting type connector according to claim 2, wherein the plurality of the contact spring pieces comprise:

a first group of leaf spring pieces having the flat plate type leaf spring pieces which extend from a first edge part of the second butting terminal fitting opposed to one side of the butting surface and whose free end sides circumscribe the butting surface and which are arranged in the configurations of the comb teeth at regular intervals to the direction of the generatrix of the butting surface; and

,

a second group of leaf spring pieces having the flat plate type leaf spring pieces which extend from a second edge part of the second butting terminal fitting opposed to the other side of the butting surface and whose free end sides circumscribe the butting surface and which are arranged in the configurations of the comb teeth at regular intervals to the direction of the generatrix of the butting surface,

wherein the leaf spring pieces of the first group of leaf spring pieces and the leaf spring pieces of the second group of leaf spring pieces are alternately arranged at regular intervals to the direction of the generatrix of the butting surface.

4. The butting type connector according to claim 3, wherein the lengths of the leaf spring pieces of the first group of the leaf spring pieces and the leaf spring pieces of the second group of the leaf spring pieces are set so that the tip end parts thereof are mutually overlapped.

5. The butting type connector according to claim 1, wherein the butting surface is an outer surface of a semi-spherical raised structure,

wherein the plurality of the contact spring pieces are a plurality of flat plate type leaf spring pieces, and

wherein the plurality of the flat plate type leaf spring pieces extend from a circumference part concentric with a center of the semi-spherical butting surface to a center of the circumference part and the plurality of the flat plate type leaf spring pieces are arranged in radial directions to the center of the circumference part.
