Definitions

  • the present invention relates to an electrical connector system, the system comprising: a first connector to be associated with a powered vehicle and second connector to be associated with a trailer attachable to the vehicle, the first connector at a female region thereof exhibiting an assembly of a plurality of sockets configured to receive and make electric contact with an assembly of a plurality of pins from a male region of the second connector, a circular space surrounding the assembly of sockets, a sleeve of circular cross-section surrounding the assembly of pins, and the sleeve configured to fit into said space.
  • connector systems in particular for use by vehicles of weight class less than 3.500 kg are either of: the old type having 7 male/female connections therein or the newer, prior art type which is currently the most used one having 13 male/female connection.
  • joining the first and second connectors of the newer, prior art type have a different challenge, as the interlocking is made using a bayonet-type of twist-locking and in addition the locking lid and bead or wing principle of the old type. Nevertheless, finding correct alignment for joining may be a challenging excercise, as the vehicle attached connector frequently is partly out of vision unless the user bends down towards the ground or road. More importantly, dirt or ice accumulating in the bayonet coupling on the second connector (male connector) may cause bayonet operation to be incomple, to disengage, to jam or in a worst case causing the short pin to engage the track bayonet failing to engage properly.
  • the ez-connector requires for a safe electrical connection and powerful interlocking the use of heavy duty, substantially ring shaped magnets which are expensive and which also require full adult manual control prior to very abrupt and powerful magnetic interlocking, and substantial adult manual power to enable the first and second connectors to become disengaged.
  • the technology is inter alia described in US 6,478,619 - B1 .
  • a further magnetic coupled connector system is known from EP 2,760,089 using pointed contact pins to abut contact faces with a force provided by strong magnets.
  • Other prior art aspects are known from WO 9326062 , EP 1,148,600 and US 5,816,825 , e.g. adapters for use if only parts of a novel system are present along with cooperating prior art parts.
  • the invention has as objects to provide a novel connector system that enables a joining operation with ease of alignment, a sufficient interlocking, and satisfactory, simple electrical connections. Further, the objects of the invention also provide for a first type of adapter operable with a female connector of the old or newer, prior art type in order in order to make use of benefits offered by the invention, without the need to replace a prior art female connector on the vehicle, and/or a second type of adapter operable with a female connector of the present novel type, without the need to replace the connector plug on the vehicle.
  • the invention also intends to offer a system which has substantial technical and operational advantages over the prior art, while providing a cost effective and technical simple solution.
  • first connector is typically used for novel connector to be located on the vehicle or car side of connection
  • second connector is typically used for a novel connector to be located on the trailer side of the connection.
  • the first connector at its female region has an opening in front of said assembly of sockets, a pair of magnets being located laterally of said circular space adjacent a wall of the space opening, and a pair of magnet anchors is located laterally of the sleeve on the second connector to releasably engage the pair of magnets upon joining of the male and female regions and interaction of the pins and sockets, as defined in attached claim 1.

  • the prior art connector 2000 is fitted with an engagement member 2001 to engage with and support the lid 1607 is in opened posture, i.e. when the connector 2000 is connected to the prior art socket connector 600 ; 1600 , both exhibiting means for mechanical bayonet type of coupling.
  • Figs. 22a, 22b and 22c illustrate in rear perspective view, in front perspective view and front end view, respectively, a novel second connector 1900 configured as a second type of adapter. Further, Figs. 23 and 24 exhibit cross-sections XXIII-XXIII and XXIV-XXIV , respectively, as shown on Fig. 22c .
  • the second connector 1900 has a rear part 1901 and a front part 1902 .
  • the rear part has a stud 1903 to engage with bayonet type coupling grooves (not shown) on the prior art trailer male connector 2000 .
  • An assembly of electrical sockets 1904 is provided in opening 1905 which encircles the assembly of sockets.
  • an engagement groove 1906 Associated with the body of the assembly of sockets is an engagement groove 1906 to engage a bead or stud (not shown) on the prior art trailer connector adjacent its assembly of electrical connection pins (not shown) thereon.
  • screws 1907 to join the two part 1901 and 1902 are located at an angle to longest axis of the oval or elliptical crosssection of the body part 1902 .
  • a pair of magnets 1908 are housed in pockets 1909 of the front body part 1902 and located at the end regions of the longest axis of the oval or elliptical crosssection of the body part 1902 .
  • the front surface of each magnet 1903 is rust-protected by a thin wall 1910 of plastics at an end of the pocket 1909 and integral with a plastics material of the body part 1902 .

  • An alignment mark 1915 is provided on the top of the second connector 1900.
  • Fig. 25 is a perpective view from above of an assembly of the novel male type of second connector 1500 and the novel type of first connector 1200 being the first type adapter. This illustrates the situation when the prior art female connector 1600 is still located on the vehicle or car and the novel second connector 1500 has been instalkled on the trailer. This triggers the use of the first connector 1200 in order to interconnect the second connector 1500 to the prior art connector 1600 .
  • Fig. 26 presents a situation when the owner the vehicle or car, as well as the trailer has not yet installed the novel first connector 1400 (female connector) and the novel second connector 1500 .
  • first connector 1200 contituting a first type of adapter
  • second connector 1900 contituting a second type of adapter
  • Such assembly of structural connectors is shown on Fig.
  • 26 which is a perspective view from above, as seen from left to right, the assembly of the prior art trailer plug/ male connector 2000 having bayonet coupling configuration, the second connector 1900 being the second type of adapter, the first connector 1200 being the first type of adapter, and the prior art vehicle associated female type connector 1600 .
