10、e required for the preparation of detail specifications for rectangular electrical connectors with integral metal housings (shells) of assessed quality for d.c. and LF applications at the full and basic assessment levels. 2 General 2.1 Contacts. Connectors designed to intermate, but which differ in
11、having removable or non-removable contacts with solder for wire, through-board solder, crimp, wire-wrap, push-on, insulation displacement etc., terminations may be included in one detail specification. The type or types of contact shall be indicated in the title of the connector specification, and f
12、or removable contacts the direction of release and removal from the connector, e.g. front release, rear removal, shall be stated. Removable contacts shall be defined in connector detail specifications by means of outline drawings and shall be identified either: a) by reference to the contact detail
13、specification to which the contacts are qualified in the series BS 9521: Removable contacts of assessed quality for electrical connectors as defined by BS 9520: Generic data, methods of test and rules for the preparation of detail specifications e.g. BS 9521 F0001; b) by means of digits indicating c
14、ontact size, wire accommodation and contact style, preceded by the connector pattern number e.g. 9523 N0001/20-20M; or c) where a) or b) cannot be applied, by an accessory number. 2.2 Assessment level. The detail specification shall show the relevant assessment level; basic, full, etc., (see 2.1.4 o
15、f BS 9520). Each detail specification shall refer to only one assessment level. The performance of connectors is normally only assessed with mated pairs from the same manufacturer and in such cases the detail specification shall include a statement to this effect. In other cases, where two or more m
16、anufacturers wish to claim functional compatability and their connectors have been tested to demonstrate such compatability, this fact and the tests employed shall be stated on the facing sheet of the detail specification. In cases where a manufacturer produces only one half of a mated connector, su
17、ch connectors may be tested with an approved mating part to demonstrate functional compatability. In such cases, the detail specification shall include a statement to this effect. In cases where two or more manufacturers wish to include a claim of functional compatability of differing connector styl
18、es, and their connectors are tested to demonstrate such compatability, the detail specification shall identify the appropriate agreed tests and include a statement to this effect. (See also 2.1.4 of BS 9520.) 2.3 Title. Connectors to detail specifications in this series have the following title: “Mu
19、lti-contact, rectangular with integral metal housing (shell).” Typical supplementary information in the title is as follows: “Panel sealed with polarized housing and rear-release, rear-removable crimp contacts.” See the example detail specification quoted in the Foreword for the method of presentati
20、on of information required to be shown on the front page. (See also BS 9000-2 and PD 9004, Circular letters Nos. 15 and 16.) 2.4 Pattern number. The pattern number of a connector or range of connectors shall consist of the relevant detail specification number without the letters BS, e.g. Pattern 952
21、3 NXXXX. 2.5 Description of the connector and intended application. The description of the connector shall make reference to the method of coupling, polarization, contact type, (crimp, solder, etc., removable, non-removable), material or finish. For connectors having removable contacts the manner of
22、 insertion, release and removal of the contacts shall be stated. Where compliance with the detail specification is dependent on a full complement of contacts being fitted and/or by the use of dummy contacts or unwired contacts with filler plugs, this shall be stated.

24、arrier and panel sealed, environment resistant, shielded, etc.,” and attention may also be drawn to particular uses, e.g. rack and panel, printed board mounting, etc.). 2.6 Marking of the component and package. The detail specification shall state that the marking shall be in accordance with 1.1.6 o
25、f BS 9520. The individual reference number required by 1.1.6 c) of BS 9520 consists of abbreviations to identify individual connectors, accessories and tools. It is not intended that this reference number shall describe every feature of the connector. An explanation of the reference shall be include
26、d in each detail specification similar to the following. 2.6.1 Connector reference numbers: Style number:A letter R denoting rectangular, followed by four digits. A typical description of a style is R 3148: Connector, fixed, crimp contacts. (The detail specification shall designate style and shall r
27、elate this number to a control drawing in the CC or FC series, e.g. CC/R 3148). Housing (shell) size/contact arrangement: A pair of digits denoting a particular housing (shell) size followed by three digits denoting a particular contact arrangement for that particular housing (shell) size. These arr
28、angements will be shown in the outline drawing section of the detail specification. In order to facilitate automatic recognition, it is necessary to standardize the number of digits used within the reference number, e.g. a housing (shell) size 1 with contact arrangement 9 will be expressed as R 3148
29、 01 009. Contact style:M = male contact. F = female contact. H = hermaphroditic contact. Termination style:C = crimp. L = through-board solder (90). E = through-board solder (90, extra long tail). S = solder for wire. T = through-board solder. W = wire-wrap (3 wraps). Z = wire-wrap (2 wraps). I = in
30、sulation displacement. X = hybrid arrangement of terminations to users requirement. Polarization:Two letters or digits denoting a particular arrangement of a polarizing feature. (Omitted where no alternative exists.) Variant:A letter or digit to denote variation from basic specification, e.g. housin
31、g (shell) finish, contact finish, etc. Detail specification shall designate variants. Where no variation exists 0 shall be used.

The specimens for each subgroup should contain representative styles and the smallest, medium and largest size for which a
44、pproval is sought. The overall sample shall include the greatest contact density for each voltage and current rating for which approval is sought in these sizes. For group D the detail specification shall include a table which indicates the combinations of connectors and accessories to be used in ea
45、ch set and which set is to be tested in which subgroup(s). 3.1.1 Full assessment level a) For subgroup D0, one specimen of each piece part for the connector range submitted for approval. For subgroup D1, three specimens of connectors for each reference number. However, this may be modified provided
46、that a sampling plan, agreed with the National Supervising Inspectorate (NSI) is appended to the detail specification. The layout of this should preferably be similar to that in Appendix C of the example detail specification. (BS 9523 F0013.) b) The minimum sample for subgroups D2 to D93) inclusive
47、is 60 specimen mated pairs complete with appropriate accessories. The minimum number of specimens for each of the subgroups D2, D3, D4, D5 and D6 is 15 pairs; subgroup D3 samples may be used for subgroup D4. For subgroups D7 and D93) it is five mated pairs; for subgroup D8(i) it is three mated pairs
48、, and these can be taken from the D2 test samples. For subgroup D8(ii) it is two mated pairs and these shall be selected from the larger sizes of subgroup D2 test samples. Alternatively separate samples may be used for subgroup D8(ii) tests. Mechanical operation. Electrical load and temperature long
49、 term (at stated current and temperature). Electrical load and temperature short term (no electrical load and at upper temperature severity). 2) Where applicable. 3) For subgroup D9, one sample pair is required for each fluid specified and if more than five fluids are specified, the extra specimens may be taken from those used for subgroup D5.
