This standard supersedes BS6361:1983 which is withdrawn. The principal change in this

10、 revision is the inclusion of Appendix A to make recommendations for the safe use of connectors on certain types of solenoid operated valves used in hydraulic systems. The text of ISO4400:1985 has been used for ease of production, although some terminology and certain conventions are not identical w

In BritishStandards it is current practice to use a full point on the baseline as the decimal marker. The Technical Committee has reviewed the provisions of ISO5598 and IE

12、C309-2, to which reference is made in the text, and has decided that they are acceptable for use in conjunction with this standard. A British Standard does not purport to include all the necessary provisions of a contract. Users of British Standards are responsible for their correct application. Com

16、er.BS6361:1988 BSI 12-1999 1 0 Introduction In fluid power systems, power is transmitted and controlled through a fluid under pressure within an enclosed circuit. Typical components found in such systems are hydraulic and pneumatic controls. These devices are used to regulate the function of a compo

17、nent or system. Some control components found in fluid power systems are electrically actuated. The electrical plug connector described in this BritishStandard is used with control and regulation assemblies for use in hydraulic and pneumatic fluid power systems. 1 Scope and field of application This

18、 BritishStandard specifies the following characteristics and requirements for a general purpose three-pin electrical plug connector with earth contact for use with a single solenoid: the electrical characteristics of the connector; the dimensions of the pins and earth contact; the means for fixing t

19、he socket to the plug; the sealing procedure between the plug and the socket. The electrical plug connector specified in this BritishStandard is intended to be used under working conditions where the connector cannot be damaged by external action (for example shock or excessive loading). 2 Reference

NOTEIf it is necessary to specify the mechanical degree of protection, reference should be made to IEC Publication529. 6 Position of pins and earth contact 6.1 The pins and earth

25、contact shall be fitted on the plug. 6.2 The earth contact pin shall be fixed in such a way that earth connection is ensured before current enters the pins. 6.3 The position, dimensions and marking information of pins and the earth contact shall comply with Figure 3. 6.4 Pins1 and2 are the main pins

30、 12-1999 Figure 4 Overall dimensionsBS6361:1988 BSI 12-1999 5 Appendix A Recommendations for the prevention of accidental interchange of directional and proportional solenoid valves used in hydraulic systems Incidents have recently occurred where a hydraulic non-proportional solenoid valve has been

31、substituted by maintenance personnel for a proportional valve. This has caused the equipment to move at high, uncontrollable speeds. The two types of valve had the following features: a) a mounting pattern which was identical; b) identical style and quantity of electrical connectors (the proportiona

32、l valves did not employ position feedback). Injury or major damage is not known to have been caused by these mistakes. However, legislation does not favour a manufacturer who has not taken all reasonable precautions to prevent an accident occurring. A survey conducted by the British Fluid Power Asso

33、ciation resulted in two main conclusions: 1) the problem of interchangeability is not limited to these two valve types, and nothing can, or should, take the place of clearly labelled valve identification plates; 2) plugs complying with this BritishStandard are those which are most frequently used. A

34、s a result of this survey it is strongly recommended that the particular pin combination shown in Figure 4 should be used for connection to the appropriate solenoid coils to segregate the two valve types.
