BL 1-1997 Page ii FOREWORD This standard was generated by the NEMA Ballast Section to satisfy the needs for connector compatibility and interchangeability by ballast manufacturers, lighting fixt
4、ure manufacturers, and users. The standard is a voluntary standard and does not imply that fluorescent lamp ballast connectors must be used or that, if connectors are used, they must be per this standard; only that compatibility and interchangeability are maintained among connectors made per this st
5、andard. Furthermore, the connector set forth in this standard is dimensionally compatible with traditional ballast can cross-sectional sizes. It is anticipated that, in the future, ballast cans will become smaller and that accordingly additional standards will be forthcoming for smaller connectors.
6、NOTE: The users attention is called to the possibility that compliance with this Standard may require use of an invention covered by patent rights. By publication of this Standard, no position is taken with respect to the validity of this claim or of any patent rights in connection therewith. The pa
7、tent holder has, however, filed a statement of willingness to grant a license under these rights on reasonable and non-discriminatory terms and conditions to applicants desiring to obtain such a license. Details may be obtained from the publisher. In the preparation of this Standards Publication, in
8、put of users and other interested parties has been sought and evaluated. Inquiries, comments, and proposed or recommended revisions should be submitted to the concerned NEMA product Subdivision by contacting the: Vice President, Engineering National Electrical Manufacturers Association 1300 North 17
9、th Street, Suite 1847 Rosslyn, VA 22209 This Standards Publication was developed by the Ballast Section.

BL 1-1997 Page 1 Section 1 GENERAL 1.1 SCOPE This standard covers a connector sys
12、tem for external connections to fluorescent lamp ballasts rated up to 347 volts and 5 amps input. The receptacle with pin assembly of the connector system covered by this standard is permanently mounted. The inclusion in this standard of receptacle assemblies that are not permanently mounted, but ar
13、e free-standing, is under consideration. It does not cover connectors intended to be connected or disconnected under loaded conditions. 1.2 REFERENCES Underwriters Laboratories Inc. 333 Pfingsten Road Northbrook, IL 60062 UL 94 Tests for Flammability of Plastic Materials for Parts in Devices and App

15、es of this standard, the following definitions apply: contact: A conductive element in a component that mates with a corresponding element to provide an electrical path. locking mechanism: A mechanical arrangement that holds a plug or connector in position when it is in proper engagement and prevent
16、s its unintentional withdrawal. plug with socket assembly: A connector that is intended to provide power to the ballast and power from the ballast to the lamp and provide a means for attachments to the electrical conductors of the ballast. It consists of a plastic plug housing containing electrical
17、socket contacts. receptacle with pin assembly: a receptacle that is intended to receive power from the line and provide power to the lamps when coupled with a mating device and that establishes connection between its own conductors and those of the plug assembly. The receptacle with pin assembly is
18、intended to be a permanent part of the ballast. It consists of a plastic receptacle housing containing electrical pin contacts. ? BL 1-1997 Page 2 ? BL 1-1997 Page 3 Section 2 GENERAL REQUIREMENTS 2.1 CONSTRUCTION The ballast receptacle with pin assembly consists of a single row of 9 pins that are e
19、qually spaced from one another. The plug with socket shall conform to the basic dimensional and spacing requirements given in Figure 2-1, and the receptacle with pin assembly shall conform to the basic dimensional and spacing requirements given in Figure 2-2. The plug with socket housing, as shown i
20、n Figure 2-1, provides two key ways on the sides of the connector in order to insure proper orientation of the plug as it is being inserted into the receptacle assembly. The plug with socket housing shall be made of a polymeric material and contain the contact terminals that mate with the current ca
21、rrying pins and the insulated lead wires. The housing provides the through-air and over-surface spacings as required by UL 840 and UL 935. The receptacle with pin assembly housing shall be made of a polymeric material that houses the current carrying pins and may have an integral locking mechanism t
22、hat mates to the plug assembly. The housing provides the through-air and over-surface spacings as required by UL 840 and UL 935. The current carrying parts or pins in the receptacle assembly shall be 0.040 ! 0.001 inches in diameter and shall be of copper or copper alloy and shall be tin plated. The
23、 contact terminals in the plug assembly are designed to mate to the pins of the receptacle assembly and to the insulated lead wire conductors, which shall be 18 gauge minimum. Acceptable materials are tinned copper alloy. Terminal dimensions shall conform to the requirements shown in Figure 2-3. The
24、 locking mechanism holds the plug into the receptacle. It may be integral to the polymeric material, as shown in Figure 2-2, or it may be incorporated into other components of the ballast provided that the configuration provides the minimum retention force required to prevent unintentional removal o
25、f the connector assembly and provided that it complies with all the dimensional requirements. 2.2 MARKING The plug with socket shall have plain, legible marking and shall include (1) the manufacturers name, trademark, or other identifying symbol, and (2) a designation including the designation of th
26、e NEMA wiring diagram. All lead location numbers need not be included, only enough to make all lead locations obvious. The ballast label shall include markings to identify the correct plug with socket assembly to use, the wiring diagram, and the warning that the connector is not intended to be used
27、for disconnect service. Industry standard NEMA designations are assigned to plug with socket assemblies based on wiring configuration. These designations shall appear on the ballast label and the plug assembly. These designations are included in Tables 2-1 and 2-2. 2.3 TESTING 2.3.1 General Requirem
28、ents Plug with socket and receptacle with pin assemblies shall be designed to provide reliable and safe performance. They shall be tested in accordance with the requirements in UL 935. ? BL 1-1997 Page 4 All tests and measurements shall be made at a temperature of 25“C ! 5“C. Reference plug and rece
29、ptacle gauges may be developed and specified so individual plugs and receptacles can be tested separately. 2.3.2 Insertion, Withdrawal and Disengagement Forces 2.3.2.1 Insertion Force The insertion force of a plug into a receptacle shall be 18 lb. maximum. Compliance shall be checked by measuring th
30、e force required to insert a test plug into a permanently mounted 9-lead reference receptacle and a reference plug into a ballast containing a test receptacle. 2.3.2.2 Withdrawal Force The connector with the latch engaged shall withstand a 20 lb force applied in a direction that would tend to discon
31、nect the plug and receptacle. Compliance shall be checked by measuring the force required to remove a test plug from a permanently mounted receptacle and a reference plug from a ballast containing a test receptacle. The force gauge should be attached to the leads of the connector and at least 8 inch
32、es from the connector. 2.3.2.3 Disengagement Force The force required to disengage the locking mechanism shall be greater than 3 lb. and less than 20 lb. Compliance shall be measured by applying a force to the latch perpendicular to the ballast mounting surface with a 1/4 inch diameter rod, while si
33、multaneously applying a withdrawal force of 10 lb. 2.3.2.4 Lead Pull-out Force Each individual lead in the plug assembly shall withstand a 20 lb. pull without being dislocated or pulled out of the plug. 2.4 Application Requirements Receptacles shall be installed in ballasts as shown in Figure 2-4, w
34、here there is one connector per ballast, and as shown in Figure 2-5, where there are two connectors per ballast. Lead positioning shall be per Tables 2-1 and 2-2 and wiring diagrams 1 through 14 in Figures 2-6 through 2-19. The connector assemblies are suitable for use in indoor or outdoor type I ba
