Patent ID: 7665203

Claim:
An insulator-combining apparatus for assembling a connector by laminating electrical insulators each hold a plurality of terminals in a lined-up form, said insulator including a wall on which the terminal is placed and an identification part which indicates order of lamination upon the assembling of the connector, the apparatus comprising: a plurality of holders which approach and leave each other, attach the insulators thereon on a condition that the walls are spaced from each other, and each include first corresponding parts corresponding to the identification parts of the corresponding insulators; a combining part which causes the holders to approach each other and laminates the insulators; and an erroneous attaching-preventing means which permits the holders to approach each other when the insulators each having the correct identification parts corresponding to the holders are attached on the holders and prevents the holders from approaching each other until the insulators combine with each other when at least one holder attaches the insulator having an incorrect identification part, wherein the holder includes: a body part provided with said first corresponding part; and a nipping part, one end part of which is rotatably provided with the body part, and which nips the insulator between the body part and the nipping part when the insulator having a correct identification part corresponding to the first corresponding part is attached on the body part, wherein the erroneous attaching-preventing means includes: a projecting pin which is provided on the nipping part of the holder and projects from the nipping part toward the nipping part of the adjacent holder; and a recess which is provided on the nipping part of the holder and penetrates through the nipping part, wherein the projecting pin provided on the nipping part of the adjacent holder is capable of entering the recess when a correct insulator is attached on the holder, while the projecting pin provided on the nipping part of the adjacent holder is prevented from entering the recess when an incorrect insulator is attached on the holder.
