Abstract
Abstract The disclosure hereof is that of thermocouple connector construction, wherein it is desired to maintain the differentiation between positive and negative contacts, which are included in the usual pair of connector members, designated male and female, so that it will be impossible to reverse the contacts and thus connection of positive and negative contacts improperly made, and in addition to effectuate a much more complete area of contact between the respective contact members so that accurate readings in thermocouple meters will be provided since the area of contact is maintained to a much greater extent than would otherwise be the case by reason of the fact that uniform pressure is exerted upon such contacts substantially over the length thereof.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
174 words
In connector construction of the class described, in combination, a generally rectilinear body having a contact end and a conductor end, a removable cover member at the said conductor end, to provide access to fastener members mounted therebeneath, a pair of passages extending from the said contact end to the cover member, one passage having a female contact unit therein and the other passage having a somewhat smaller contact unit therein, said units each comprising a pair of complementary shell members of arcuate cross section arranged to receive a male contact member therein, one of such male members being larger than the other; said shell members having flattened sections to position the said shell members to receive the fastener members aforesaid, and each pair of shell members having a spring pressure part surrounding the same to exert uniform pressure on the shell members and thereby such male contact members when the latter are positioned therein, limiting means being provided for the smaller contact unit to prevent insertion of the larger male contact member therein.
Claim 2
Dependent Claim
174 words
In connector construction of the class described, in combination, a generally rectilinear body having a contact end and a conductor end, a removable cover member at the said conductor end, to provide access to fastener members mounted therebeneath, a pair of passages extending from the said contact end to the cover member, one passage having a female contact unit therein and the other passage having a somewhat smaller contact unit therein, said units each comprising a pair of complementary shell members of arcuate cross section arranged to receive a male contact member therein, one of such male members being larger than the other; said shell members having flattened sections to position the said shell members to receive the fastener members aforesaid, and each pair of shell members having a spring pressure part surrounding the same to exert uniform pressure on the shell members and thereby such male contact members when the latter are positioned therein, limiting means being provided for the smaller contact unit to prevent insertion of the larger male contact member therein.
Claim 3
Dependent Claim
102 words
The combination as claimed in claim 1, wherein each spring pressure part comprises a base formed to receive a pair of the shell members therein, a series of spring arms extending from said section and along the said members, said arms having pressure portions to engage the shell members near the contact end of the body to apply uniform contact pressure on a male contact member positioned in said unit, said arms further having portions intermediate their ends arranged to coact with the wall of the passage in the body in which the contact unit is positioned to produce the pressure described.
Claim 4
Dependent Claim
68 words
The combination as claimed in claim 2, wherein the base consists of an expandible member substantially surrounding the shell members, and having portions to centralize the base in the passage, and the free ends of the arms of one of the contact units are provided with thickened areas to limit their outward movement within the passage and thereby prevent the insertion of the larger male contact member therein.
Claim 5
Dependent Claim
22 words
The combination as claimed in claim 3, wherein the ends of the arms are reversely bent to provide the thickened areas described.
Claim 6
Dependent Claim
60 words
The combination as claimed in claim 1, wherein the shell members are formed with flanges along their edges in the plane of the flattened section, and the spring pressure part includes a base of nearly closed C-shaped cross section, certain of the flanges of the shell members being positioned between the open ends thereof, and maintained in this position thereby.
