Definitions

  • the present invention relates to a retaining latch for retaining a plug within a receptacle of an electrical connector, especially to be handled by a remotely operated vehicle in subsea use, the retaining latch having a base structure shaped bent around a central axis of the retaining latch and comprising at least one latching element configured to be brought into engagement with the plug.
  • the invention relates to a receptacle housing for a socket of an electrical connector, especially to be handled by a remotely operated vehicle in subsea use.
  • the electrical connectors with sockets having receptacle housings comprising bodies with retaining latches of the kind mentioned above are known from the prior art, as in US 5,639,255 .
  • the electrical connectors further comprise plugs, which are designed to be mated with the sockets in subsea conditions.
  • plugs which are designed to be mated with the sockets in subsea conditions.
  • connectors have to be very rugged and water tight, since they are exposed to high pressure under water (e.g., -2000 to -3000 meters below sea level), as well as sand and mud.
  • ROV remotely operated vehicles
  • the connectors are also called wet-matable ROV connectors.
  • the connectors have to allow for a connection by simple push/pull action for mating and unmating, respectively. They are designed to ensure e.g., 100 connection cycles. Their design life is e.g., 25 years. Connection and disconnection forces of the connectors are rated.
  • the connectors may comprise e.g., 4, 7, 8, or 12 electrical contacts, which are arranged within the receptacle body.
  • the contacts may comprise contact pins, which are not protected by a particular insulation.
  • terminals or cavities accommodating these terminals for receiving and electrically contacting the pins may be closed by insulation caps or membranes supported by springs. These insulation caps or membranes have to be pushed out of the way by the contact pins against forces exerted by the springswhen the connector is mated. In the fully mated position of the connector, these springs are always loaded and exert a force onto the plug, which tends to push the plug out of the socket, i.e., unmate the connector.
  • the retaining latch is required for holding the plug within the socket in the fully mated position.
  • the retaining latches are designed as rings received within the housing, i.e., body of the connector, and comprising a plurality of locking tabs (e.g., 8 contact points) extending away from the ring-like basic structure of the retaining latch, essentially in parallel to the plug direction, e.g., central axis.
  • the tabs engage with an annular groove formed in the outer circumference of the plug, so that they may exert a retention force onto the plug, which holds the plug in place in the fully mated position.
  • an object underlying the invention is to provide a retaining latch, body, and receptacle housing enabling high and stable retention forces over the desired number of connection cycles and design life under subsea conditions.
  • a retaining latch according to claim 1 wherein the latching sections of the retaining latch provide two latching elements as a part of the bent basic structure, which is elastically deformable radially away from the central axis.
  • the object is achieved in that the wall is provided with two slots extending from outside of the body into the receptacle and perpendicularly to a middle axis of the receptacle along the outer circumference of the body for receiving the latching sections of the retaining latch according to the present invention.
  • the object is achieved in that the receptacle housing comprises a retaining latch according to the present invention and a body, wherein the retaining latch is fitted around the outer circumference of the body such that the at least one latching element extends through the at least one slot into the receptacle.
  • the design of the retaining latch and the body may be very robust for withstanding subsea conditions and manipulation.
  • the latching sections are formed as a part of the base structure of the retaining latch. A part of this structure consitutes the latching elements.
  • the latching element may be formed directly at the basic structure, i.e., base body of the retaining latch. The latching element may jut above the inner circumference of the wall of the body into the receptacle.
  • the plug may then simply push the latching element away radially while it is axially fixed within the slot.
  • the plug may be formed so that it comprises a lead-in angle between a counter lead-in chamfer and a central axis of the retaining latch, which counter lead-in angle is bigger than a lead-out angle between a counter lead-out chamfer and the central axis, so that during mating, i.e., insertion of the plug into the socket, the latching element is smoothly pushed away, while higher retention forces than insertion forces have to be overcome when unmating the connector, i.e., pulling the plug out of the socket.
  • the basic structure may be U-shaped or essentially annular, such as ring-like, around the central axis, which provides an embracing property of the latch.
  • the latching section may extend essentially perpendicularly to the central axis. At least increments of the latching section may extend perpendicularly to the central axis.
  • the latching section with the latching element may be easily bent radially outwards during insertion of the plug and snap back into place behind a retaining bulge, rim, and/or within a counter-latching element, e.g., a groove of the plug in order to retain it in a fully mated position.
  • the latching section may extend essentially linearly between two rounded spring sections of the retaining latch. Between the rounded spring sections, the retaining latch, i.e., the latching sections thereof, may extend essentially straight lined, whereas in the spring sections, the retaining latch may extend non-linearly. Thereby, the latching section may overlap in a projection along the central axis, i.e., plug direction of the electrical connector comprising the receptacle.
  • a height of the retaining latch measured between the rounded spring sections may be bigger than a width of the retaining latch measured between the latching section and a section of the retaining latch opposing the latching element with respect to the central axis.
  • the height of an aperture formed by the basic structure may be bigger than a width of the aperture.
  • the retaining latch may have an oblong shape, so that the latching section is located at one of the long sides, which may more easily be elastically deformed than the narrow sides comprising the spring sections.
  • the oblong shape of the retaining latch also enables that a circular diameter arranged concentrically with respect to the central axis may overlap with the latching section, but not with the spring sections. Hence, a plug and socket with a circular diameter may be easily brought in engagement, i.e., overlap along the plug direction with the latching section.
  • Performing the latching operation between the latching section of the retaining latch and the counter-latching or retaining section of the plug may be facilitated in that a radial elasticity of the retaining latch in the region of the latching section exceeds a radial elasticity of the retaining latch in the region of the spring section.
  • the retaining latch may be easily widened radially away from the central axis when inserting or withdrawing the plug into or out of, respectively, the socket.
  • the spring section may extend along at least two different radii. Thereby, the elasticity and spring characteristics of the spring section may be adapted to the particular requirements the retaining latch has to fulfill in a certain application.
  • a first radius of the at least two radii may be arranged between the latching section and a second radius of the at least two radii, wherein the first radius is smaller than the second radius.
  • the second radius may be an encompassing radius of a circle line arranged concentrically to the central axis.
  • the first radius may be a connecting radius of a circle line arranged acentric to the central axis, which connects the latching section to the region of the spring section with the encompassing radius.
  • the shape, e.g., oblong shape, and spring characteristics of the retaining latch may be easily adapted to the respective requirements.
  • the latching sections are provided with a lead-in chamfer and a lead-out chamfer.
  • the latching sections are provided with a bevel facing in against the plug direction.
  • the retaining latch has an hexagonal cross-section in a cross-sectional plane extending in parallel to the central axis. This facilitates widening the retaining latch in a latching section when the plug impinges on the respective bevel, i.e., lead-in chamfer or lead-out chamfer, when being inserted into or withdrawn from, respectively, the socket.
  • each of the latching sections provides a latching element, so that e.g., two latching elements may extend into the receptacle perpendicularly to the plug direction in a way that they oppose each other with respect to the middle axis of the body. Thereby, the plug may be held firmly within the at least two latching sections. Providing at least two latching sections opposing each other may also help to center the plug about the middle axis of the body and the central axis of the retaining latch, and therefore within the socket.
  • the retaining latch may be formed symmetrically with respect to at least one of a vertical axis extending perpendicularly to and through the central axis, and a horizontal axis extending perpendicularly to the horizontal axis and the central axis through their crossing point.
  • the retaining latch may be formed point-symmetrically with respect to the central axis. This facilitates evenly distributing the retaining forces and centering the plug within the socket.
  • the retaining latch may be integrally formed of plastic.
  • a plastic e.g., an organic thermoplastic polymer, especially polyether ether ketone (PEEK) may be used, because of its good ratio of elastic limit in proportion to rigidity.
  • PEEK polyether ether ketone
  • the retaining latch may be precisely held at the body of the receptacle housing in that lateral abutment faces are formed in the at least one slot and extend essentially perpendicularly to the middle axis for supporting the latching section.
  • the abutment faces may face outwardly so that the latching section may be supported on the abutment faces.
  • At least one of the spring sections may be held at a distance from the outer circumference of the body. Thereby, the spring sections may have sufficient clearance in order to approach the body when the retaining latch is widened by the at least one latching section without limiting the movement of the spring section towards the receptacle housing by the other circumference thereof. Both spring sections may be distanced from the body. At least a part of the spring sections may extend concentrically to at least one of the inner and outer circumference of the body. The central axis of the retaining latch and the middle axis of the tubular body may be superimposed for a symmetrical arrangement of the retaining latch and the body with respect to each other.
