  • the first surface 41 is in contact with a side face 26 that is a longitudinal other end side of the housing 15. Accordingly, not the entire periphery of the first surface 41 is surrounded by the step d, and the longitudinal other end side thereof is open.

  • the large diameter portion 43 has a diameter slightly larger than the collar portion 17.
  • a side of an inner peripheral surface thereof in an anti-pressing direction relative to the pressing surface 33, i.e., a longitudinal one end side thereof is more inclined by an angle of ⁇ toward the second surface 42 in the anti-pressing direction.
  • the abutting portion 44 is a tapered surface whose diameter becomes smaller toward a back side in the depthwise direction.
  • a tapered angle of the abutting portion 44 relative to the depthwise direction of the housing 15 is larger than an angle of the tapered surface 19 relative to the depthwise direction of the collar portion 17.

  • FIG. 5 is a cross-sectional view of the electrical wire insertion hole (after insertion).
  • FIG. 5 indicates a state where there is no inclination in the ferrule terminal 18 with the collar portion 17.
  • the ferrule terminal 18 with the collar portion 17 is inclined toward the longitudinal one end side relative to the depthwise direction, and contacts with the pressing surface 33. Accordingly, the diameter of the large diameter portion 43, the angle ⁇ , the tapered angle of the abutting portion 44, the diameter of the small diameter portion 45, and the like are set to readily allow for slight inclination of the ferrule terminal 18 with the collar portion 17 when the ferrule terminal 18 is inserted.
  • the abutting portion 44 abuts with the leading end 17a of the collar portion 17 to inhibit further insertion.
  • the abutting portion 44 is set such that a gap is formed between a leading end of the terminal portion 18a of the ferrule terminal 18 and the intermediate base 46, so that, as illustrated in FIG. 5 , the leading end of the terminal portion 18a is adapted not to contact with the intermediate base 46 when the ferrule terminal 18 is inserted.
  • the step d is set such that when the tapered surface 19 of the collar portion 17 abuts with the abutting portion 44, the proximal end 17b of the collar portion 17 is located between the first surface 41 and the second surface 42.

  • FIG. 6 is a perspective view illustrating the step between the first surface and the second surface (after insertion).
  • the proximal end 17b of the collar portion 17 is located between the first surface 41 and the second surface 42. Accordingly, it is visually recognizable whether the work of insertion has been correctly completed or not. Specifically, when the proximal end 17b of the collar portion 17 is positioned between the first surface 41 and the second surface 42, it indicates that insertion has been completed, whereas when the proximal end 17b of the collar portion 17 projects from the first surface 41, it indicates that the amount of insertion is insufficient. In this way, it can be easily recognized by the simple structure that insertion work has been correctly completed, without any need for addition of a new component.
  • the plate spring 34 When the ferrule terminal 18 is inserted into the electrical wire insertion hole 24, the plate spring 34 is pushed by the ferrule terminal 18 and elastically deformed. Then, when the ferrule terminal 18 is inserted between the leading end of the plate spring 34 and the pressing surface 33, the elastic force of the plate spring 34 presses the ferrule terminal 18 against the pressing surface 33, and inhibits displacement in the pull-out direction. Accordingly, loosening and come-off of the ferrule terminal 18 can be inhibited.
  • the large diameter portion 43 is larger than the collar portion 17, and the side of the inner peripheral surface in the anti-pressing direction relative to the pressing surface 33 is more inclined by the angle of ⁇ toward the second surface 42 in the anti-pressing direction.
  • the tapered angle of the abutting portion 44 and the angle of the tapered surface 19 are made different from each other.
  • the small diameter portion 45 is larger than the ferrule terminal 18. This allows the ferrule terminal 18 with the collar portion 17 to be fitted into the electrical wire insertion hole 24 with some play. Accordingly, the ferrule terminal 18 with the collar portion 17 is allowed to be slightly inclined and can be surely contacted with the pressing surface 33 when the ferrule terminal 18 is inserted, so that the quality of
  • the abutting portion 44 is the tapered surface
  • the invention is not limited thereto. It will suffice to inhibit further insertion by its abutment with the leading end of the collar portion 17 when the ferrule terminal 18 is inserted.
  • the abutting portion 44 may be merely a step.
  • the invention is not limited thereto.
  • the tapered angle of the abutting portion 44 relative to the depthwise direction may be made smaller than the angle of the tapered surface 19 relative to the depthwise direction. This facilitates allowing for inclination of the ferrule terminal 18 with the collar portion 17.
  • the tapered angle of the abutting portion 44 relative to the depthwise direction may be made coincident with the angle of the tapered surface 19 relative thereto as long as the inclination of the ferrule terminal 18 with the collar portion 17 is allowed by play of the collar portion 17 relative to the large diameter portion 43 or play of the ferrule terminal 18 relative to the small diameter portion 45.
  • the invention is not limited thereto, and is also applicable to a-contact relays and b-contact relays.
  • the relay with the four pole contacts has been described, the invention is also applicable to relays with a single pole contact, two pole contacts, or three pole contacts.
  • the invention is applicable not only to relays but also to timers.
  • the invention is not limited thereto. In short, the invention is also applicable to any other electrical equipment or auxiliary equipment having a spring terminal structure capable of holding the ferrule terminal 18 with the collar portion 17 inserted into the housing 15.
