Abstract
A modular jack connector is arranged to optionally accommodate both a ferrite block inductor arrangement and chip capacitors. The connector can be assembled and all components secured in place in four insertion steps, without any requirement for soldering or other bonding techniques.
Claims15
In a modular jack connector, comprising a housing having a plug-receiving opening, opposed top and bottom surfaces joined by opposed side surfaces extending from said opening to a back surface, and a plurality of elongated contacts mounted to the housing, each contact including a contact portion at one end extending diagonally into the opening, a vertical portion at a second end and an intermediate portion between said contact portion and vertical portion, and means defining a plurality of grooves in said top surface of said body for positioning said contacts, the improvement wherein:
- at least one of said contacts includes a substantially vertical portion and a horizontal portion which together forms a notch in said contact, a chip capacitor seated in the notch, and wherein:
- said connector further includes a shield having a top surface, opposed side surfaces extending from a front opening to join a back surface, and tines inwardly extending from said top surface to engage said capacitor.
A shield for a modular jack, comprising:
- a top surface joined by opposite side surfaces and a rear surface, tines inwardly extending from said top surface to engage electrical components in the modular jack, tines inwardly extending from said side surfaces to lock said shield on the modular jack, outwardly extending tabs for engaging a panel, and tabs extending into an opening in the modular jack for engaging a plug inserted into the modular jack, and
- further comprising a tab on said shield which extends into a cutout in said jack to engage a bottom surface of said cutout and thereby form a spark gap between the tab and contacts positioned in grooves in said bottom surface.
An electrical connector, comprising:
- a body member;
- at least one electrical contact positioned in said body member;
- grounding means for grounding said contact through a first electrical component;
- first positioning means for removably positioning said first electrical component in said body member such that first and second electrodes of the electrical component respectively engage the contact and the grounding means;
- and
- second positioning means for positioning in said body member an inductor electrically coupled with and surrounding said contact,
- wherein said first and second positioning means comprise communicating passages in said body member, and
- wherein said at least one contact is a plurality of contacts, and said inductors are in the form of a ferrite block having a plurality of bores through which said contacts are inserted, said ferrite block being positioned within at least one of said passages in said body member and including grooves arranged to engage projections in said one of said passages to position the ferrite block therein.
