1、Designation: E 1129/E 1129M 081Standard Specification forThermocouple Connectors1This standard is issued under the fixed designation E 1129/E 1129M; the number immediately following the designation indicates theyear of original adoption or, in the case of revision, the year of last revision. A numbe
2、r in parentheses indicates the year of lastreapproval. A superscript epsilon () indicates an editorial change since the last revision or reapproval.1NOTEThe year date was corrected editorially in July 2009.1. Scope1.1 This specification covers separable single-circuit ther-mocouple connectors with t
3、wo round pins. Connectors coveredby this specification must be rated for continuous use to at least300 F (150 C), but they may optionally be rated higher.1.2 This specification does not cover multiple-circuit con-nectors, multi-pin connectors, miniature connectors, or connec-tors intended primarily
4、for panel mounting. High temperatureconnectors (for example, those designed for continuous use attemperatures above approximately 500 F (260 C) are notintended to be covered by this specification.1.3 The values stated in either inch-pound units or SI unitsare to be regarded separately as standard.1.
5、4 The following precautionary statement pertains only tothe test method portion, Section 9, of this specification. Thisstandard does not purport to address all of the safety concerns,if any, associated with its use. It is the responsibility of the userof this standard to establish appropriate safety
6、 and healthpractices and determine the applicability of regulatory limita-tions prior to use.2.

Terminology3.1 Definitions: The definitions given in Terminology E 344shall apply.3.2 Definitions of Terms Specific to This Standard:3.2.1 connector pair, nan assembly consisting of a plugand a jack, each having both positive and negative inserts, thatwill connect two parts of an electrical
9、circuit and provide ameans of physically disconnecting the two parts without theuse of tools.3.2.2 contact insert, nmetallic conductor assemblies that,when installed in connector bodies, provide connections be-tween two parts of an electrical circuit. Plug connectors willcontain projecting prong con
10、tacts, while jack connectors willcontain recessed socket or receptacle contacts.3.2.3 service life, ninterval of time that a connectorassembly will be put to use and retain all physical andthermoelectric properties.3.2.4 test difference, napparent thermoelectric differenceattributable to mated conne
11、ctors observed by the test procedureof this specification.4. Significance and Use4.1 The widespread use of thermocouple connectors re-quires standardization of mating dimensions and performancecharacteristics.4.2 This specification describes standardized thermocoupleconnector dimensions and capabili
12、ties and includes test proce-dures suitable for evaluating the performance of a particularspecimen or design. The tests described are not intended forroutine inspection or rapid testing of large groups of connectorsor for quality control purposes.5. Classification5.1 Plugs or Jacks:1This specificati

15、700, West Conshohocken, PA 19428-2959, United States.5.1.1 Connectors shall be constructed as either plugs orjacks, and these two forms shall be designed to connect witheach other.5.1.2 Plug connectors shall have two external prong con-tacts of differing diameters to prevent improper mating. Thenega
16、tive prong shall be the larger, as shown in Table 1 and Fig.1.5.1.3 Jack connectors shall have two internal socket con-tacts sized and spaced to receive and accommodate the prongcontacts of the mating plug. Jack connectors shall also includea means of producing and maintaining sufficient contactpres
17、sure to meet all of the other requirements of this specifi-cation.5.2 ANSI/ASTM Type:5.2.1 Connectors shall be produced in versions to matcheach of the standardized ANSI/ASTM thermocouple types asgiven in Table 2.5.2.2 The insert materials of each plug and jack shall havethermoelectric properties co
18、nforming to the characteristics ofextension grade material of the corresponding thermocoupletype as given in Specification E 230 over the temperature rangespecified in Table 3.5.2.3 Calibration conformance and gradient testing is notapplicable to Type B thermoelectrically neutral (Cu/Cu) con-nectors
19、.6. Ordering Information6.1 Orders for connectors under this specification shallinclude the following:6.1.1 Quantity of plugs or jacks (specify which),6.1.2 ANSI/ASTM thermocouple type (see Table 2),6.1.3 Any optional accessories that may be required, such asthose listed in 7.4.3,6.1.4 Special testi
20、ng requirements, and6.1.5 Requirements for certificates of conformance to thespecifications or reports of the results of any required testing.7. Materials and Manufacture7.1 Body:7.1.1 The dimensions of the connector bodies shall fallwithin the limits given in Table 1.7.1.2 The connector body shall
21、be made of an electricallyinsulating material capable of continuous use at any tempera-ture between 0 F (-18 C) and 300 F (150 C) for the servicelife given in Table 2, without losing its ability to conform tothis specification.7.1.3 The connector bodies shall be color coded in accor-dance with Table
22、 2 to provide rapid and permanent identifica-tion of the thermocouple calibration with which it is designedto be used. Each plug and jack shall be permanently markedwith a symbol or symbols to identify positive and negativeconductor inserts.All connectors shall bear the suppliers nameor other means
23、of source identification, unless otherwisespecified in the purchasing documents.7.1.4 An insulating barrier shall be incorporated into eachconnector body to prevent inadvertent contact between ther-moelements or wires.7.2 Inserts:7.2.1 Contact inserts may be either solid or hollow as longas all of t
