Abstract

<P>PROBLEM TO BE SOLVED: To provide an inexpensive electric connector of a large stroke capable of securing stable electric continuity. <P>SOLUTION: This electric connector 10 comprises an insulation substrate 2 inserted with a volute spring 1. The longitudinal-directional central part of the outermost circumference in the volute spring 1 forms a flange part 1c wound one more turns. A stepped through hole 21a for insertion-penetrating the outer cylinder 1d of the volute spring 1 is formed in a main body 21 of the insulation substrate 2. The diameter in a stepped part 21b side of the through hole 21a is larger than that of the through hole 21a, and the flange part 1c of the largest diametric part is fit thereinto. A cover of the substrate 2 is indicated by 22, and is formed with a through hole 22a concentric to the insertion hole 21a and having a diameter substantially equal to that of the through hole 21a, so as to insertion-penetrate the outer cylinder 1d. The cover 22 is joined with the main body 21 after the volute spring 1 is inserted. <P>COPYRIGHT: (C)2004,JPO

However, in the case of a conventional electrical connector such as the former, in the case of a leaf spring type, a large stroke can be obtained, but there is a limit to miniaturization. If it is smaller than the current state, it will not be possible because it will exceed the spring limit. In the case of the coil spring type, the size can be reduced, but the conductor diameter is small and the resistance value is large, so that current cannot flow. A large number of windings causes problems at high frequencies. In the case of the bamboo shoot spring type, a large stroke is taken and the electrical characteristics are good. However, it is a contact on one side. The opposite side has a large contact area. In the case of the contact probe type, the electrical characteristics are good, but there is a problem that it is expensive.

Next, the effects of the first embodiment of the present invention will be described. When the end surface of the bamboo shoot spring 1 comes into contact with the electrode surface, which is a conductive member, the leading end portion presses against the electrode by an appropriate biasing force of the spring portions 1a and 1b, thereby ensuring electrical conduction. The bamboo shoot spring 1 can take a sufficiently large stroke and can obtain stable conduction with respect to the electrode surface. Therefore, even when a large stroke is required, it can be advantageously applied to the miniaturization and thinning of the electric connector. The bamboo shoot spring 1 is made of a single component and can be manufactured at low cost. Furthermore, since the spring portions 1a and 1b are housed inside the outer cylinder 1d, the spring position does not change in the planar direction while the electrical connector 10 is operating, and is stable.

That is, of course. Further, the bamboo leaf spring is attached to the insulating substrate by a method of sandwiching the same between the main body and the cover. Alternatively, the outer cylinder 1d or 3d may be pressed into the through hole of the insulating substrate. Alternatively, a tab (a plate piece protruding radially outward) may be integrally formed on the outermost periphery of the bamboo shoot spring, and this tab may be engaged with a through hole of the insulating substrate by radially protruding the tab.
