Abstract
Abstract A connector checking apparatus includes a connector checking device having a main body operable by a lever to move toward a connector. The connector checking device also has a connector support. Detection pins are slideably disposed within the main body and are connected to checking terminals. The detection pins have a conductive contact face and detection fingers on a detection piece. Upon insertion of the detection pins into the connector, complete insertion of the terminals within the terminal receiving cavities of the connector permits contact between the conductive face and an end of the terminal C. The connector has cantilever resilient supporting pieces which include a locking projection 14a. The device can detect whether or not the connector checking device A is completely engaged with the connector.

Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
258 words
A connector checking device comprising: a connector support for supporting a connector with a plurality of terminal receiving cavities, wherein the connector has a cantilever resilient supporting piece for supporting a terminal; a main body independently movable to and from said connector support; and a plurality of detection pins disposed in said main body and urged toward the connector support by resilient means, said detection pins being connected to detecting electrical circuits, each of said detection pins having a conductive contact face and a detection finger extending beyond said conductive contact face; wherein, said main body is moved toward said connector support for checking to determine whether the terminal is completely inserted within the connector, such that when the terminal is completely inserted within the connector, contact occurs between the terminal and said conductive contact face, whereas when the terminal is incompletely inserted with the connector, said detection finger proceeds into a space in said connector where said cantilever resilient supporting piece deflects by being bent; and wherein said connector includes a terminal receiving cavity and a tapered guide face is formed at a front end of a side wall with the cantilever resilient supporting piece in the terminal receiving cavity of the connector; and wherein a tapered contact face is formed at a tip of said detection finger such that, when incomplete insertion occurs, and said tapered contact face opposes the tapered guide face formed at the front end of the side wall with the cantilever resilient supporting piece in the terminal receiving cavity of the connector.

Claim 3
Dependent Claim
300 words
A connector checking device comprising in combination: a connector having a plurality of terminal receiving cavities, each of said terminal receiving cavities respectively having a cantilever resilient supporting piece supporting a terminal therein; a connector checking member having a base, a connector support for supporting said connector, and a main body selectively movable toward and away from said connector support; a plurality of detection pins disposed in said main body; and urging means for urging said plurality of detection pins toward said connector support, each of said detection pins being respectively connected to detecting electrical circuits, and each of said detection pins having a conductive contact face and a detection finger extending beyond said conductive contact face toward said connector support; wherein, said main body is moved toward said connector support for checking to determine whether the terminal is completely inserted within said connector, such that when the terminal is completely inserted within said connector, contact occurs between said terminal and said conductive contact face, whereas when the terminal is incompletely inserted with the connector, said detection finger proceeds into a space in said connector where said cantilever resilient supporting piece deflects by being bent so that no electrical contact occurs between said terminal and said conductive contact face; wherein said connector includes a terminal receiving cavity and a tapered guide face is formed at a front end of a side wall with the cantilever resilient supporting piece in the terminal receiving cavity of the connector; and wherein a tapered contact face is formed at a tip of said detection finger such that, when incomplete insertion occurs, and said tapered contact face opposes the tapered guide face formed at the front end of the side wall with the cantilever resilient supporting piece in the terminal receiving cavity of the connector.
