  • a heat-shrinkable tubing 7 having an adhesion effect is mounted to cover from the connecting portion 3 to the lead wire 5.
  • the coil device sealed by the heat-shrinkable tubing 7 is effective in cases to provide a simple protection from water such as when it is used in an atmosphere where dew condensation is possible.
  • a problem when such a device is used in water or oil More specifically, since the elasticity of the heat-shrinkable tubing 7 is impaired when being shrunken for sealing, a clearance is likely to be formed between the tubing 7 and the lead wire 5 if the lead wire 5 is shaken in order to be arranged or for other reason. It is difficult to expect a perfect sealing effect.
  • the present invention was developed in view of the above problem and an object thereof is to secure sealability at a lead wire drawing portion.
  • a coil device in which a connecting portion is formed on a covering element made of an insulating material for substantially accommodating a coil, a connection terminal connected with the coil projects from the connecting portion and is connected with at least one lead wire, wherein a rubber or sealing plug having at least one insertion hole through which the lead wire is insertable in a watertight manner is fitted on the connecting portion, and a cover preferably made of a material having a high rigidity for covering the rubber or sealing plug is fitted.
  • the rubber or sealing plug is satisfactorily closely adhered not only to the lead wire, but also to the relatively hard connecting portion, providing a good sealing. Further, since the rubber or sealing plug is covered by the cover preferably having a high rigidity, it is stably held even if the lead wire is shaken, with the result that a secure sealing can be expected. According to a preferred embodiment of the invention, the cover is provided with at least one insertion piece to be at least partly inserted into the connecting portion or an insertion portion thereof.
  • the cover itself can be stably held by having the insertion piece thereof inserted into the connecting portion.
  • connection terminal is provided within an area where the connecting portion is formed.
  • the formed connecting portion can be taken out of a mold without bringing a parting line to the outer circumferential surface of the connecting portion if the connection terminal remains within the connecting portion forming area without bulging therefrom.
  • the outer circumferential surface of the connecting portion can be securely made smooth, ensuring an excellent sealability of the rubber plug.
  • connection terminal is substantially round tubular.
  • connection terminal is substantially round tubular, such a construction of the mold as to prevent resin from leaking into the connection terminal can be simplified.
  • a coil device in particular according to one of the preceding embodiments of the invention, in which a connecting portion is formed on a covering element made of an insulating material for substantially accommodating a coil, wherein a (projecting) portion of a connection terminal connected with the coil projects from the connecting portion, and a fastening portion directly connectable with a core of a lead wire is formed at this projecting portion.
  • the lead wire is drawn from the coil device while being connected with the coil.
  • the lead wire can be directly fastened to the connection terminal without providing separate parts such as intermediate terminals, the number of parts and the number of operation steps can be reduced, with the result that production costs can be reduced.
  • the fastening portion is a barrel to be fastened to the core of the lead wire by being crimped.
  • the core of the lead wire is connected with the connection terminal by being fastened to the barrel.
  • the fastening portion is an insulation-displacing blade to be brought into contact with the core of the lead wire while cutting an insulation coating of the lead wire.

Lips 40 are formed on the inner surface of each insertion hole 39.
  • a cover 41 for substantially covering the outer surface of the rubber plug 35 is also provided.

  • a pair of first crimping or bending pieces 42 project from the opposite shorter sides of the bottom end of the cover 41, and a second crimping or bending piece 43 projects from one of the longer sides. Further, the bottom end of the other longer side serves as an insertion end 44 at least partly insertable into the insertion slot 21 of the connecting portion 14.
  • a pair of pressing pieces 45 are formed in the substantially middle of the longer sides of the upper end of the cover 41 with respect to widthwise direction by being bent inward at an angle different from 0° or 180°, preferably substantially at right angles in advance.
