Abstract
Description
- The present invention relates to electrical connectors and to a method of assembling such connectors.
- This invention is particularly, although no exclusively, with cylindrical electrical connectors, and more particularly with electrical connectors in which a plurality of electrical contacts are supported in an insulating insert assembly, the insert assembly being fixed in a substantially cylindrical shall. Such connectors are described, for example, in British Standard Specification No. BS9522, and are commonly, but not exclusively, used in the aerospace industry. A typical connector assembly includes a fixed connector whose insulating insert supports a plurality of pin type female contacts and a free connector whose insulating insert supports a plurality of pin type male contacts. The fixed and free connectors may rapidly connect and disconnect by means of a knurled coupling nut and, once connected, should remain connected under adverse environmental conditions which may include extreme temperature variations and high vibration. Various forms of ratchet type anti-decoupling mechanisms have been proposed in order to maintain a pair of connectors together under adverse conditions. British Patent No. 1585438, for example, discloses a connector in which the other surface of the cylindrical shell is provided with an annular shoulder having a number of outwardly extending gear teeth which contact a plurality of substantially straight leaf springs assembled to the inner surface of the coupling nut. Each spring lies tangential to the shoulder and has a central inwardly directed projecting member which engages the gear teeth. British Patent No. GB 2042822B discloses a substantially similar arrangement in which the spring and the projecting member are of a plastics material. such arrangements have a number of practical disadvantages. First, the arrangements disclosed in the above numbered patent specifications require the springs first to be assembled to an inner surface of the coupling nut before the cylindrical shell is inserted into the nut and the projecting members engage the gear teeth. Supporting the springs during this assembly procedure is a delicate and time consuming operation, particularly when assembling small connectors. Second, a connector of a given size is generally suitable for use with only one design of spring, and there is no flexibility for varying the ratchet torque. Third, the spring projecting members, whether of metal or plastics material, are prone to wear if the connector is coupled and decoupled many times while in service and finally, the arrangements illustrated require precisely defined cavities or holes to be formed in an inner surface of an unthreaded portion of the coupling nut into which a spring or a spring fixing pin must be inserted in order that the spring may be properly positioned to engage the gear teeth. If the nut is of a metal material, as is commonly the case, the forming of such cavities or holes, in addition to the aforementioned assembly procedure, is likely to be a time consuming and costly process, particularly when manufacturing small connector assemblies.
- According to one aspect of the present invention an electrical connector includes a first and second housing each supporting an insert portion including a plurality of electrical contacts, the housings being arranged to threadably engage each other whereby relative rotational movement in a first direction of one housing relative to another housing is arranged to cause relative translational movement of the insert portions to connect the electrical contacts, the connector being characterised in that a rotation inhibiting assembly is provided between one insert portion and the housing which supports that insert portion in order to inhibit relative rotation between that insert portion and the housing, the assembly including at least one sprung element which has been located in one of at least two positions on one of the insert portion and housing in one of which positions at least the sprung element is arranged to co-operate with a series of teeth located on the other of the insert portion and housing, in order to vary the force which inhibits relative rotation between the insert portion and housing. With such an electrical connector the torque of the rotation inhibiting assembly can be varied either during assembly of the connector by selecting the position of the sprung element or, alternatively or additionally, the torque can be altered on an already assembled electrical connector by selecting a different position for a sprung element. The sprung element may be arranged to co-operate with the teeth in at least two positions with the force which inhibits relative rotational movement between the insert portion and housing varying in dependence upon the position of the sprung element.
- The selection of the position of the sprung element may be achieved by altering the orientation of the sprung element on the insert portion or housing on which it is located. In one orientation of the sprung element, more teeth may be engaged by the sprung element than at another orientation of the sprung element.
- Movement in one rotational direction of the sprung element relative to the insert portion or housing on which it is located may be prevented or limited by abutment of one end of the sprung element with a portion of the insert portion or housing on which it is located and movement in the other rotational direction of the sprung element relative to the insert portion or housing on which it is located may be prevented or limited by abutment of the other end of the sprung element with a different portion of the insert portion or housing on which it is located.
- The sprung element may be held in place by being located in a cavity defined between the teeth, circumferentially spaced portions on the insert portion or housing on which it is located and axially spaced portions on either side of the sprung element.
- The connector may include a plurality of sprung elements, and the sprung elements may be substantially equally circumferentially spaced from each other.
- According to another aspect of the present invention a method of assembling an electrical connector as herein referred to may comprise selecting one of at least two possible positions of the sprung element in one of which positions at least the sprung element co-operates with the teeth.
- According to a further aspect of the present invention an electrical connector includes a first and second housing each supporting an insert portion including a plurality of electrical contacts, the housings being arranged to threadably engage each other whereby relative rotational movement in a first direction of one housing relative to another housing is arranged to cause relative translational movement of the insert portions to connect the electrical contacts, the connector being characterised in that a rotation inhibiting assembly is provided between one insert portion and the housing which supports that insert portion in order to inhibit relative rotation between that insert portion and the housing, the assembly including at least one sprung element located on one of the insert portion and housing arranged to co-operate with a series of teeth located on the other of the insert portion and housing, to inhibit relative rotation between the insert portion and housing, movement in one rotational direction of the sprung element relative to the insert portion or housing on which it is located being prevented or limited by abutment of one end of the sprung element with a portion of the insert portion or housing on which it is located and movement in the other rotational direction of the sprung element relative to the insert portion or housing on which it is located being prevented or limited by abutment of the other end of the sprung element with a different portion of the insert portion or housing on which it is located. The sprung element may be held in place by being located in a cavity defined between the series of teeth, circumferentially spaced portions on the insert portion or housing on which it is located and axially spaced portions on either side of the sprung element.
- The invention will now be described, by way of example only, with reference to the accompanying drawings in which:-
- Figure 1 is a perspective view of a connector assembly showing fixed and free connectors,
- Figure 2 is an exploded perspective view of a multiple spring free connector according to one embodiment of the invention,
- Figure 3 is a diametric part-sectional view of a four spring free connector according to an embodiment of the invention.
- Figure 4 is a rear end view of the connector of Figure 3 with a rear support washer and a retaining clip removed.
- Figure 1 shows a typical connector assembly in which a fixed connector 1 includes a dielectric insert 2 supporting a plurality of cylindrical female contacts 3. Referring to Figure 2, a
free connector 1A includes a substantiallycylindrical shell 4 which encloses adielectric insert 2A supporting a plurality of mating pin typemale contacts 3A. Each insert and its pin contacts is supported in the associated connector by means such as are described, for example, in our pending European Patent Application No. 85303548.3. The free connector is provided withsplines 5 locating withgrooves 6 in the fixed connector to ensure alignment of the male and female contacts when the fixed and free connectors are assembled together, and aknurled coupling nut 7 encircling thefree connector shell 4 may be screwed and tightened on toexternal threads 8 on the fixed connector when the two connectors are assembled, in known manner. - The
knurled coupling nut 7, when assembled, surrounds the substantiallycylindrical shell 4 and the inner surface of the front portion of the nut is internally threaded for screwing to the externally threadedend region 8 of the fixed connector 1. - A plurality of substantially gull wing shaped, or w-shaped,
leaf springs 11 are inserted intocavities 12 lying in an annular cylindrical space between the inner surface of a rear, unthreaded, region of thecoupling nut 7 and a ring of radially outwardly facinggear teeth 13 on a raised shoulder in the central region of the outer surface of thecylindrical shell 4. Theleaf springs 11 fit loosely into thecavities 12 if inserted before thecoupling nut 7 is assembled around the cylindrical shell, as is shown in Figure 2. Figures 3 and 4 shown an assembled free connector having foursprings 11 in associatedcavities 12. It will be appreciated that the number of springs and cavities provided may vary from two to any desirable number, and thecavities 12 are preferably evenly spaced around the cylindrical shell. - The base of each cavity is provided by the
gear teeth 13 and the opposite face of each cavity is provided by the inner surface of the coupling nut. The front wall to each cavity is provided by a locatingwasher 14 resting in a recess in thecoupling nut 7, as is shown in Figure 3. A plurality of evenly spacedlugs 14A, Figure 4, with appropriately tapered side walls are provided on the rearward facing surface of the locatingwasher 14 such that thelugs 14A extend rearward of thegear teeth 13 and the tapered side walls provide side walls to thecavities 12. - When the component parts of a free connector are assembled together the
coupling nut 7 is first placed around theshell 4 and its associatedinsert 2A such that thegear teeth 13 align with the required position for thesprings 11 as is shown in Figure 3. - The locating
washer 14 is then inserted around the shell and into the nut from the rear of the connector. One or more locating protrusions (not shown) extend frontwards of the locating washer into suitably positioned recesses (not shown) in the unthreaded interior of the nut such that, when inserted, the locating washer cannot rotate relative to the nut. Thesprings 11 are then inserted into thecavities 12 formed by the gear teeth, the side walls of the rearward facinglugs 14A the rearward facing portions of the locating washer lying between the protrusions, and the inner surface of theshell 4. The springs are dimensioned such that, as shown at 11 in Figure 4, one apex of the spring engages theteeth 13 to provide a ratchet mechanism for the coupling nut. Alternatively, a spring may be designed such that two apices engage the teeth, as is shown at 11R in Figure 4. The spring and washer geometry may be so chosen that the springs may be reversible and one or more of the springs may have the apices engaging the teeth or vice-versa. Alternatively, the geometry may be such that in the "normal" position with one apex engaging the teeth, a reversed spring may not physically engage the teeth, but may be stored in its cavity to be re-reversed and increase the overall torque of the ratchet mechanism. - When the springs have been inserted into their associated cavities, a retention washer or a rear support washer 15 and a retaining lock ring or
clip 16, Figures 2 and 3, are assembled to the rear of the connector to close the cavities after the springs have been inserted. Thewasher 15 is a tight fit in the open rear end of thecoupling nut 7 and the lock ring is located in a groove of theinsert 2A (not shown). - It will be appreciated that the present invention provides a great deal more flexibility in choice of ratchet torque than has hitherto been achievable in providing the option of reversible springs. Additionally, while it may be necessary to provide a metal rather than a plastics coupling nut, the locating washer may conveniently comprise a low cost plastics moulding. A range of locating washers, having different lug geometries, may be provided for a shell of a particular size, thereby providing a choice in the number of spring cavities for a given coupling nut design. The coupling nut remains essentially cylindrical, without requiring precisely machined cavities for spring supports, since the necessary precision will occur in the plastics moulding. A further advantage of the present invention lies in using an apex of a w-shaped or gull-wing shaped leaf spring to engage the gear teeth. The leaf spring would normally be formed of a spring steel material, which is mechanically hard and wear resistant while resilient to the passage of gear teeth. Such a spring is likely to provide improved wear resistance compared with the spring designs disclosed in the aforementioned prior art.
- Alternative embodiments of the invention will be apparent to those skilled in the art. For example, if disassembling the connector is unlikely to be required in service, the lock ring or
clip 16 may be dispensed with and the rear portion of the coupling nut may be swaged or otherwise formed over therear support washer 15. The rear support washer may alternatively be fixed to the coupling nut by means of suitable screw thread or glue. - In a further alternative embodiment, the side walls of each cavity may, instead of being provided by the spaced
lugs 14A of theseparate locating washer 14, be provided by machining out a portion of the coupling.
