ABSTRACT:
An internally split type jack, comprising: a casing, the casing having a front end wall formed with a plug inlet hole and partition walls having plug passage holes formed therein aligned coaxially with the plug inlet hole and of substantially corresponding diameter, an inner casing wall of each housing space having a slot closed at one end formed therein; a plurality of electrical contact pieces mounted one in each of the housing spaces, each of the contact pieces comprising: a main body with a further plug passage hole therein substantially corresponding in diameter to the plug inlet hole; cooperating resilient contact-makers disposed on opposite sides of the further plug passage hole; and, one side edge adapted to slidably engage in the slot and so properly position the contact piece in the housing space to align the further plug passage hole coaxially with the plug inlet hole and the plug passage holes; and, at least one abutment disposed in at least one of the housing spaces to limit outward movement of at least one of the resilient contact-makers, whereby a plug inserted into and withdrawn from the jack will be guided during movement by the plug inlet hole and the plug passage holes, thereby passing smoothly through the further plug passage holes in the contact pieces, and will be resiliently clamped between the contact-makers of each contact piece during full insertion, the contact pieces being protected from damage due to misaligned movement of the plug into and out of the jack.
