Abstract
Abstract A filter adaptor capable of being quickly inserted between two adjacent leads feeding into a printed circuit (PC) board connector. The adaptor comprises an insulating body having two spring contacts for insertion into the PC board connector, a low pass filter, and a contactor within said body for establishing contact between incoming leads and the filtered contacts.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
143 words
A lead receiving filter adaptor for insertion into the connector assembly of a circuit board comprising: a body made of insulating material; two spring contacts extending outwardly from within said body for insertion into the connector assembly; a dual contactor within the body provided with a pair of contact elements insulated from each other, a tubular filter provided with an input terminal, an output terminal and a common terminal, with the input and output terminals respectively connected to one of said contact elements and one of said spring contacts, means connecting the common terminal of the filter to the other contact element and other spring contact, and receptacles within said body for the insertion of two leads whereby one lead will contact one contact element of said dual contactor and the second lead will contact the other contact element of said dual contactor.
Claim 2
Dependent Claim
143 words
A lead receiving filter adaptor for insertion into the connector assembly of a circuit board comprising: a body made of insulating material; two spring contacts extending outwardly from within said body for insertion into the connector assembly; a dual contactor within the body provided with a pair of contact elements insulated from each other, a tubular filter provided with an input terminal, an output terminal and a common terminal, with the input and output terminals respectively connected to one of said contact elements and one of said spring contacts, means connecting the common terminal of the filter to the other contact element and other spring contact, and receptacles within said body for the insertion of two leads whereby one lead will contact one contact element of said dual contactor and the second lead will contact the other contact element of said dual contactor.
