Definitions

  • the invention relates to a seal for sealing a longitudinal object, such as a wire, said seal having an axial cavity for receiving said longitudinal object in a fully mounted position, said axial cavity being open on both axial ends for at least partially receiving said longitudinal object through said axial cavity, the seal comprising a first partial body, a second partial body and a third partial body, the second partial body and the third partial body both being made of a similar material, the first partial body being made of a different material, wherein the first partial body forms a base onto which the second partial body is affixed in a non-removable manner such that the second partial body is at least partially positioned outside the first partial body in a radial direction, wherein the third partial body is at least partially configured to be positioned inside the first partial body along at least a part of the axial cavity and wherein the first partial body is made of a material which is relatively more rigid as compared to the material making up the second partial body and the third partial body.
  • Seals that provide the dual functionality of providing a holding or dampening function on wires in addition to their sealing functionality are known.
  • the requirement of rigidly holding the electrical conductor wire requires different mechanical properties of the seal as contrasted with the requirement of providing soft and supple features that contact and seal against a cavity in an electrical connector to properly seal against the insides of such a cavity.
  • This contrast in the mechanical requirements at different locations within a seal lead to different materials being selected for different parts of the seal.
  • DE 195 46 963 discloses a cylindrical sealing unit for use with an electric wire or cable that is inserted through a center bore.
  • the center bore is located in a bushing made using a relatively hard material.
  • Sealing lips are molded on to the outer surface of the bushing, and are made of a flexible material that is secured around a flange on the bushing.
  • the assembly has a main sealing section and a separate section that is crimped to provide a secure seal on the cable.
  • the relatively harder material is configured to be in contact with the electrical conductor wire or its insulation on the inside, while a softer material is used to manufacture the sealing lips to the outside.
  • WO 2013/178727 discloses an electrical connector comprising at least one electric cable surrounded by an insulating sheath and a housing arranged on at least a portion of the electric cable.
  • the housing is made of a first material.
  • the electrical connector further comprises a sealing arranged on the electric cable and surrounding the insulating sheath in a sealing manner.
  • the sealing is made of a second material.
  • the housing is molded over the sealing and over at least a portion of the cable to encompass the sealing.
  • the relatively softer material is configured to seal against the insulating sheath and is mechanically supported and held in place by the comparatively mechanically rigid housing.
  • the wire seal comprises a solid member and an elastic member, wherein the elastic member is partly arranged inside and outside a cavity which is formed by the solid member.
  • a seal that is assembled from two parts, a solid part and an elastic part is known from JP H01 112575 U .
  • the elastic part is provided with sealing lips which are arranged circumferentially inside a cavity for receiving a cable.
  • a seal is known that consists of a rigid body and a second partial body made from softer material for receiving a longitudinal object.
  • the object of this invention is thus to provide a solution that provides better sealing properties both between the seal and the connector housing and also between the seal and the electrical conductor wire, simultaneously.
  • This object is achieved by a seal as defined in claim 1, made of different materials where the comparatively softer material is configured to be in contact inwardly with the electrical conductor wire and outwardly with the connector housing.
  • the first partial body has at least a first axial region and a second axial region, wherein a collar for providing a dampening effect to the longitudinal object in the fully mounted position is formed contiguously with the second partial body and the third partial body, the collar being located adjacent to the second axial region of the first partial body, and wherein the collar is formed on the circumferential edge of the first partial body, on a surface facing away from a crimping region that corresponds with the first axial region, the first axial region being configured to be crimped onto the longitudinal object, wherein the first axial region is provided with cuts in the axial direction along at least a part of the first axial region to allow radial deformation of said first partial body in a compressive direction when crimped.
  • a seal according to this invention may also be configured to provide adequate contact between the rigid material forming the seal and the electrical conductor wire and/or contact between the rigid material forming the seal and the connector housing.
  • the contact between the rigid material forming the seal and the electrical conductor wire may allow the rigidity of the seal material to impart mechanical fixation and/or stability to the electrical conductor wire. This contact may be where the seal is fixed onto the electrical conductor wire or at another location that would serve to limit movement of the electrical conductor wire.
  • Contact between the rigid material forming the seal and the connector housing may allow the seal to be optimally positioned within a cavity of the connector housing into which it may be inserted.
  • the seal according to this invention may be suitable for sealing a longitudinal object, such as an electrical conductor wire that may be received in an axial cavity in the seal.
  • the axial cavity is open on both axial ends and may receive the longitudinal object through the axial cavity either partially or completely.
  • a partially inserted longitudinal object such as an electrical conductor wire may be provided with a cap and sealed by crimping the cap in place.
  • a longitudinal object such as an electrical conductor cable or wire may be inserted through the axial cavity to emerge at the other end.
  • the part of the longitudinal object that emerges at the side opposite to the insertion end may be assembled onto a terminal. Assembly may be achieved by crimping the conductor wire to the terminal in a conductor crimp zone while the insulation may be crimped along with the seal at an insulation crimp zone of the terminal.
  • the first partial body is provided with at least one set of cuts. Such cuts extend through the first partial body at least through a part of its length in the axial direction.
  • the cuts in the first partial body allow radial deformation of the first partial body both in a compressive as well as an expansive direction.
  • the cut When crimped, the cut allows portions of the first partial body to move closer and to better crimp against the insulation of the electrical conductor wire extending through the seal.
  • the cuts allow the expansion of the effective inner diameter of the first partial body. Such an expansion may be achieved by the abutment of the electrical conductor wire or when a metal sleeve is inserted through the seal during an automatic wire insertion process.
  • the cuts may further allow the seal to accommodate a larger range of electrical conductor wire thicknesses as compared to a rigid, static first partial body without any cuts. A judicious selection of the frequency and positioning of the cuts on the first partial body may be made to ensure the optimal radial deformation properties in conjunction with the required strength and rigidity of the first partial body.
