3、cense from IHS-,-,-SIZE CAGE CODE DWG NO. 1. SCOPE 1.1 Scope. This drawing outlines the requirements for a specific member of a family of compact, high contact density (.050 inch (1.27 mm), high performance two-piece electrical connectors. These connectors are intended for printed circuit board (plu
4、g in dual heat sink daughter board modules, and fixed backplane) applications utilizing surface mount daughter board and compliant pin backpanel termination techniques. The connector family includes members that provide combinations of low power signal contacts, power contacts, shielded contacts and
5、 optical termini. These connectors may be used in severe operating environments, and may include protective hoods, contact sealing, interfacial seals, electrostatic shielding and other features. This connector family is organized and fabricated utilizing modular design, with connector module blocks
6、which can be grouped to provide for combinations of low power signal contacts, fiber optic termini, power contacts, and shielded contacts. Specific implementation groupings of these module blocks constitute elements of the connector family. This drawing details a backpanel member of the connector fa
7、mily, composed of groups of 10 insulator block contact assemblies for low power fork type contacts, providing a total of 452 signal contacts. This assembly mates with a companion daughter card connector per DSCC drawing 04027. The backpanel connector assembly also includes an electrostatic shield wh
8、ich mates with a daughter card connector metal shroud, providing an electrostatic shield for all contacts in the connector pair. The backpanel connector insulator blocks also provide for installation of three connector keyed bushings, and allows for use of a center guide pin. This family member does
9、 not include module blocks containing fiber optic, power, or shielded contact elements. These members of this connector family are included DSCC drawings 93003 through 93013. 1.2 Part or Identifying Number (PIN). The complete PIN shall be as specified on the item requirements drawing and constructed
10、 using the following format: 04028 A A 45200 E S NDSCC Insulator Termination Contact Termination Keying Contact requirement material style number tail length pin sealing drawing (see 1.2.1) (see 1.2.2) (see 1.2.3) (see 1.2.4) (see 1.2.5) (see 1.2.6) 1.2.1 Insulator material. Insulator material shall
11、 be fabricated using one of the following plastic materials: A - Thermoplastic, type GPT-30F in accordance with MIL-M-24519, or ASTM-D-5138. 1.2.2 Termination style. Connectors shall be terminated using the following termination techniques: A - Compliant pin termination. 1.2.3 Contact number. The PI
12、N shall include 5 digits to identify the total number of contacts. The first three digits will identify the number of signal contacts, with the following two digits identifying the number of special contacts (shielded, fiber optic, power).
