Definitions

  • the present disclosure relates to electrical connectors comprising a socket for mutually engaging with a header to provide electrical connection for one or more conductors of the socket to one or more conductors of the header.
  • Embodiments of the present technique can provide an electrical connector comprising a socket and a header which includes a locking mechanism between the socket and the header which can reduce an anti half mating possibility between the socket and the header.
  • an electrical connector is known to provide an arrangement for providing electrical connection between electrical components and are used in a variety of electrical devices.
  • an electrical connector can comprise two parts in which one or more conductors from one part are arranged to be electrically connected to one or more conductors of the other part when the two parts are mated.
  • an electrical connector In some environments the electrical connection provided by an electrical connector can be compromised. For example, in automotive applications electrical components which are manufactured separately and then assembled on a production line must be provided with an electrical connector which allows those parts when assembled to be electrically connected. However a nature of automotive applications can mean that the electrical connector is subject to vibration and/or significant temperature changes as well as the presence of foreign bodies such as dirt and contamination. Therefore it is desirable to provide an arrangement in which an electrical connector can provide electrical connection between electrical components which ensures an increased reliability of the electrical connection provided by the electrical connector.
  • connection between two parts of the electrical connector may be made during assembly between two electrical components, and the assembly may restrict access to the parts of the electrical connector which must be mated at a point in the assembly process, it is also desirable to provide an arrangement in which a false mating of the two parts of the electrical connector is more easily detectable.
  • EP 2 020 706 A2 relates to a connector, to a connector assembly and to a connection method therefore, in which an object is to improve the reliability of a connection detecting function of a connector.

  • a housing of the socket and a housing of the header include locking arms, which together form a locking mechanism which is configured to provide an anti-half mating feature for the electrical connector.
  • Anti-half mating is an expression which is used in the following description to describe an advantageous technical effect, in which it is easier to detect when the parts of the electrical connector have not mated correctly or completely in an engaged state although it may appear that they have been mated.
  • the housing of one of the header and the socket includes a first locking arm resiliently connected by a cantilever for example to the housing, the first locking arm including a first projection having a first cam surface, the first projection being arranged to project into a space between the first locking arm and an adjacent surface of the housing.
  • the adjacent housing surface includes a second projection having a second cam surface, the second projection being arranged to project into the space between the first locking arm and the housing surface towards the first projection.
  • the housing of the other of the socket and the header includes a second locking arm having first and second engaging surfaces, which are configured forward from a first recess and a second recess formed in the second locking arm.
  • the first engaging surface is configured to engage the first cam surface of the first projection of the first locking arm, and the second engaging surface being configured to engage the second cam surface of the second projection of first locking arm as the socket and the header are advanced towards each other causing the first locking arm to be displaced from a closed position against a biasing force provided by the cantilever to an open position to allow the second locking arm to pass into the space between the first locking arm and the adjacent housing surface.
  • the first projection on the first locking arm is received into the first recess on the second locking arm, and the second projection on the adjacent housing surface is received in the second recess formed in the second locking arm so that the first locking arm can return to a closed position.
  • the second locking arm is thereby held by the first and the second projections by the first locking arm and the housing.
  • a first feature of an electrical connector is that the electrical connector comprises a socket for mutually engaging with a header to provide electrical connection for one or more conductors of the socket to one or more conductors of the header, the socket comprising a socket housing configured to hold one or more socket-side conducting terminals each of which is adapted and arranged mutually to engage with a corresponding header-side conducting terminal to provide electrical connection to the one or more conductors of the socket, and the header comprising a header housing configured to hold one or more of the header-side conducting terminals mounted within the housing to provide electrical connection to the one or more conductors of the header, each of the one or more of the header-side conducting terminals being configured mutually to engage with a corresponding one of the one or more socket-side conducting terminals when the socket is mated with the header, wherein the housing of one of the socket or the header includes a first locking arm flexibly connected to the housing, the first locking arm including a first projection having a first cam surface, the first projection being arranged to project into
  • the second locking arm is resiliently connected to the housing, the resilient connection allowing the head of the second locking arm to be displaced in a plane substantially perpendicular to a plane of the first locking surface so that the second locking surface can be displaced away from the housing adjacent surface to dis-engage from the first locking surface
  • the first projection includes a third cam surface and the head of the second locking arm includes a third engaging surface on an adjacent side to the first engaging surface, which engages with the third cam surface as the head of the second locking arm is displaced away from the housing adjacent surface, the third cam surface and the third engaging surface displacing the first locking arm as the second locking arm is displaced away from the housing adjacent surface and retracted from the first locking arm with the second locking surface displaced to be clear from the first locking surface allowing the second locking arm to be retracted from the first locking arm.
  • a second feature of the electrical connector according to the present invention is that the second projection includes a first locking surface adjacent to the second cam surface on the adjacent housing surface, and the second locking arm includes a second locking surface partly defining the second recess, the first locking surface being configured to engage the second locking surface to prevent the second locking arm from being retracted from the space between the first locking arm and the adjacent housing surface.
  • a third feature of the electrical connector according to the present invention is that the first locking arm is resiliently connected to the housing, the resilient connection allowing the first locking arm to be displaced in a plane perpendicular to a plane of insertion of the header to the socket by engagement of the first cam surface with the first engaging surface and the second cam surface with the second engaging surface as the header and the socket are mated.
  • the housing of one of the header and the socket includes a locking chamber, the first locking arm forming part of one side of the locking chamber and the housing adjacent surface forming an adjacent side of the locking chamber, the adjacent side including the second projection, and at least two adjacent walls of the locking chamber being configured to engage with corresponding walls of the second locking arm to constrain movement of the socket and the header in a plane perpendicular to the direction of mating between the conducting terminals of the header and the conducting terminals of the socket.

  • the retainer 110 is used to hold the female terminals 120 within the socket housing 122.
  • this is just one example and it will be appreciated that in other examples, different arrangements can be made for retaining the female terminals 120 within the socket housing 122, such as for example crimping the terminals onto the respective conductors and inserting the terminals into the housing.
  • a mating section 180 of the socket 104 is received within a cavity formed within the header housing 132 to provide a more accurate alignment of the male through pins 130 and the female terminals 120 so that when mating occurs the male through pins 130 are co-axially located and received within the female terminals 120.

  • the through or male pins 130 can be arranged to provide electrical connection to one or more components, for example which are mounted on a circuit board or in an automotive component of which the header 102 forms part.
  • a first section of the through pin 300 is configured to project forward of the header housing 132 within the cavity of the header housing 132 so that when the socket 104 and header 102 are mated together, the first section of the through pin 300 can be received within the receiving channel 202 of the female terminal 120.
  • a second section 302 of the through pin 130 extends through the header housing 132 and protrudes rearward of the header housing 132 to form the rearward pins 108 for providing electrical connection to a component for which the electrical connector 100 is providing electrical connection.
  • a central section 304 is configured to include a profile which engages with a profiled receiving channel of the header housing 132 in order to fix the through pin 130 within the header housing 132.
  • the profile of the male through pin 130 also includes retaining projections 308 which embed within the walls of the receiving channel of the header housing 132.

  • the engagement of the flange 306 within the recess 620 also ensures that the first section 300 of the male through pin 130 ( Figure 4a and 4b ) extends a distance d 2 from the forward side of the header 102.
  • a cavity 630 is formed within the header housing 132 into which the male through pin 130 protrudes the distance d 2 .
  • the cavity 630 is configured to receive a mating section 180 of the socket.

Walls of the mating section 180 of the socket housing 122 therefore engage with walls of the cavity 630 to restrict lateral movement of the socket 104 with respect to the header 102 as they are advanced towards each other to ensure that the male through pin 130 is received within the receiving channel 200 through the opening 202 of the female terminal 120.

Furthermore the retaining projections 308 formed in the side of the male through pin 130 engage with the walls of the receiving channel 610 to ensure that the male through pins 130 are secured within the receiving channel 610.
  • the male through pins 130 are secured within the header housing 132 and the female terminals 120 are held within the socket housing 150, it will be appreciated that in other embodiments the male though pins 130 could be held by the socket housing 150 and the female terminals 120 could be held within the header housing 132. Indeed other terminal configurations are possible other than the specific examples of the male through pins 130 and female terminals 120 other than those presented in Figures 1 to 6 .
  • Embodiments of the present technique can provide an arrangement in which a locking mechanism secures a header 102 of an electrical connector 100 to a socket 104 which both secures the mating of the header 102 to the socket 104 and provides an anti-half mating feature.
  • a locking mechanism secures a header 102 of an electrical connector 100 to a socket 104 which both secures the mating of the header 102 to the socket 104 and provides an anti-half mating feature.

  • a third view 906 the third cam surface 770 of the first projection 700 engages with the third engaging surface 772 of the second locking arm 150 as the first locking arm 140 begins to return to its closed position.
  • the first locking arm 140 has returned to its closed position.
  • the first and second locking surfaces 762, 764 are configured to engage so that the head 701 of the second locking arm 150 engages with the second projection 704 to prevent the socket 104 and header 102 from being separated.
  • a cross sectional view is provided with the socket 104 and header 102 mated and the first locking arm 140 in its closed position engaging with the second locking arm 150 in which the first projection 700 is positioned within the recess 760 in the upper side of the second locking arm 150 and the second projection 704 within moves into the recess 730 on the reverse side of the second locking arm 150.
  • Embodiments of the present technique therefore provide an arrangement in which a positive biasing force must be provided to the second locking arm 150 to deflect the first locking arm 140 and because of the arrangement of the first and second cam surfaces 720, 724 and the first and second engaging surfaces 722, 726 of the first and second locking arms 140, 150 respectively, a resistive force is provided in a direction which is in a reverse direction to an insertion force being applied to mate the header 102 and the socket 104.
  • An anti half mating feature is thereby provided by the locking mechanism between the socket 104 and the header 102 of the electrical connector 100 because a threshold force must be applied to deflect the first and second locking arms 140, 150 from their neutral or closed positions in their locked and dis-engaged states in order to mate the socket 104 and the header 102 and to lock the first and second locking arms 140, 150 together.
