Abstract

An interface section 200 of a structure 100 includes a plurality of contacts 120 , each of the contacts having a contact portion 122 and a spring portion 126 which supports the contact portion 122 so that the contact portion 122 is displaceable in an up-down direction. The contact portions 122 of the contacts 120 are arranged in a pitch direction (X direction), and reinforcement portions 166 are positioned between the contact portions 122 , respectively. The structure reinforces a side portion of the contact portion 122 . Therefore, even if the contact portion 122 receives a force along the pitch direction (X direction), damage of the contact 120 can be prevented.

First claim

The invention claimed is:

1. A structure comprising:
a plurality of contacts each having a contact portion and a spring portion supporting the contact portion so that the contact portion is displaceable along an up-down direction, each of the contact portions having two reinforced portions;
a holder member holding the plurality of contacts so that the plurality of contacts are arranged in a pitch direction perpendicular to the up-down direction and that side surfaces of the reinforced portions of neighboring ones of the contact portions face each other in the pitch direction;
a reinforcement member having a reinforcement portion, the reinforcement portion is positioned between the neighboring contact portions when the reinforcement member is positioned at an initial position, so as to reinforce, at least in part, the reinforced portions facing each other; and
urging means for urging the reinforcement member to move towards the initial position.

2. The structure according to claim 1 , wherein:
the reinforcement member has a plurality of the reinforcement portions; and
two of the plurality of the reinforcement portions are positioned, in the pitch direction, outside of outermost ones in the pitch direction of the contact portions.

3. The structure according to claim 1 , wherein:
the reinforcement member has a coupling portion and arm portions, the coupling portion supporting the reinforcement portions and coupling the arm portions; and
the arm portion is supported by the holder member to be rotatable so that the reinforcement portion is displaceable in the up-down direction.

4. The structure according to claim 1 , further comprising a case accommodating the holder member, wherein:
each of the arm portions is formed as a part of the case and extends in a front-back direction perpendicular to both the up-down direction and the pitch direction; and
the reinforcement portion is supported by the arm portion so as to be displaceable in the up-down direction.

5. The structure according to claim 1 , wherein the spring portion urges the contact portion to project from the holder member.

6. The structure according to claim 1 , wherein a size of the reinforcement portion in the pitch direction is more than two third of a distance between the neighboring contact portions.

7. The structure according to claim 1 , wherein:
the contact is further formed with a supporter portion which extends from the contact portion and supports the reinforcement portion;
the contact uses the support of the reinforcement portion by the supporter portion and resilience of the spring portion to also serve as the urging means; and
a displacement of the reinforcement are connected with another displacement of the contact portion.

8. The structure according to claim 7 , wherein the supporter portion has a size larger than that of the contact portion in the pitch direction.

9. The structure according to claim 1 , wherein:
the urging means is formed of a resilient member distinct from the contact; and
a displacement of the reinforcement portion is independent of another displacement of the contact portion.

10. The structure according to claim 1 , wherein:
the structure is connectable with a, mating structure which has a plurality of mating contact portions and a plurality of protrusion ribs;
the mating contact portions and the protrusion ribs are arranged alternately in the pitch direction;
the protrusion rib projects from the mating contact portion by a predetermined size in the up-down direction; and
a distance between a top of the contact portion and an uppermost portion of the reinforcement portion in the up-down direction is larger than the predetermined size.
