Abstract
Abstract A contact of a connector made of an elongated resilient material and having an inner end fixed to a connector housing and a midway to be in contact with a mating contact of another connector. According to the invention, the contact comprises a substantially straight portion extending from a contacting portion of the midway with the mating contact to the fixed inner end, and an outer portion being bent in zigzag extending from the contacting portion to the distal end abutting against a surface of the connector housing, thereby obtaining a sufficient contacting resilient pressure to realize stable and reliable connecting condition with the mating contact and simultaneously achieving small-sized connectors and high speed signal transmission.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
122 words
A contact of a connector formed of an enlongated resilient material comprising, an inner end fixed to a connector housing and a midway to be in contact with a mating contact of another connector to be connected to the first mentioned connector, said contact including a substantially straight portion extending from a contacting portion of said midway to said fixed inner end and an outer portion extending from said contacting portion to a distal end of said contact, said outer portion being bent in generally s-shaped configuration and said distal end abutting against a surface of said connector housing said abutting distal end being movable along said connector housing in a direction opposite to the direction of insertion of said mating contact.
Claim 2
Dependent Claim
122 words
A contact of a connector formed of an enlongated resilient material comprising, an inner end fixed to a connector housing and a midway to be in contact with a mating contact of another connector to be connected to the first mentioned connector, said contact including a substantially straight portion extending from a contacting portion of said midway to said fixed inner end and an outer portion extending from said contacting portion to a distal end of said contact, said outer portion being bent in generally s-shaped configuration and said distal end abutting against a surface of said connector housing said abutting distal end being movable along said connector housing in a direction opposite to the direction of insertion of said mating contact.
Claim 3
Dependent Claim
28 words
A contact as claimed in claim 1 in which said distal end of the contact has a flat edge which abuts against the surface of the connector housing.
Claim 4
Dependent Claim
28 words
A contact as claimed in claim 1 in which said distal end of the contact has a flat surface which abuts against the surface of the connector housing.
Claim 5
Dependent Claim
34 words
A contact as claimed in claim 1 in which said distal end of the contact is beveled at its edge to prevent the surface of the connector housing from being scraped by the edge.
Claim 6
Dependent Claim
34 words
A contact as claimed in claim 1 in which said distal end of the contact is rounded at its edge to prevent the surface of the connector housing from being scraped by the edge.
Claim 7
Dependent Claim
27 words
A contact as claimed in claim 1 in which said midway of the contact has a cross-sectional configuration in point-contact with a surface of said mating contact.
Claim 8
Dependent Claim
31 words
A contact as claimed in claim 1 in which said connector housing includes a projection abutting against said straight portion of the contact so that it is subjected to a preload.
