On a leading end side of the collar portion 18 is formed a tapered surface 18a whose diameter becomes smaller toward the leading end thereof, and the terminal portion 19 is thinner than a diameter of the collar portion 18.
- the plate spring 34 engages with the terminal portion 19 in the inside of the housing 15 to suppress displacement in a pull-out direction. Additionally, when a tool (unillustrated) is inserted into the tool insertion hole 25, the engagement with the terminal portion 19 is released in the inside of the housing 15.
- the electrical wire insertion holes 24 formed on the secondary-side terminal section 14 are all the same in structure, and thus, the electrical wire insertion hole 24 formed on the lower stage will be exemplified for description hereinbelow.

- 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 is larger than an angle of the tapered surface 18a relative to the depthwise direction.
- the small diameter portion 45 has a diameter smaller than the diameter of the collar portion 18 and larger than a diameter of the terminal portion 19.
- the plate spring 34 is formed of, for example, stainless steel, and has a uniform plate thickness of about 0.5mm.
- the plate spring 34 includes a free end-side region 51, a fixed end-side region 52, a first bent region 53, a second bent region 54, and a tool contact region 55.
- a position where the terminal portion 19 passes in the inside of the housing 15 is defined as a terminal path 56 (an electrical wire path) .
- the free end-side region 51 is a region that is arranged such that a leading end of the region 51 linearly projects toward a back side in an insertion direction and the terminal path 56, and a plate surface of the region 51 intersects with the terminal path 56 and that is urged against the pressing surface 33.

- the fixed end-side region 52 is a linear shaped region fixed to the intermediate base 46 and extending in parallel with the terminal path 56.
- the first bent region 53 is a region interposed between the free end-side region 51 and the fixed end-side region 52 and bent toward a side that projects when seen from a front side in the insertion direction.
- the curvature radius is set to be twice or more than the plate thickness, and preferably three times or more than that. Accordingly, herein, the curvature radius is preferably set to 1.5 mm or more.

- FIG. 4 is a cross-sectional view of a state where the terminal portion is in abutment with the free end-side region of the plate spring.
- the terminal portion 19 passes through the small diameter portion 45, and a leading end 19a of the terminal portion 19 abuts with the plate surface of the free end-side region 51 of the plate spring 34.
- the leading end 19a of the terminal portion 19 pushes the plate surface of the free end-side region 51 of the plate spring 34 toward the back side in the depthwise direction. Then, a range of from the free end-side region 51 to the tool contact region 55 pivots around a curvature center of the first bent region 53 serving as a fulcrum, and narrows an opening degree of the tool contact region 55 with respect to the fixed end-side region 52, i.e., elastically deforms the plate spring 34 in a closing direction.
- FIG. 5 is a cross-sectional view of a state where the leading end of the terminal portion has reached the leading end of the free end-side region.
- an angle ⁇ formed by the terminal portion 19 and the free end-side region 51 is set to be within 45 degrees ⁇ 2 degrees.
- the free end-side region 51 projects toward the back side in the insertion direction.
- displacement of the terminal portion 19 in the insertion direction occurs in a forward direction, which is therefore permissible.
- displacement thereof in the pull-out direction occurs in an opposite direction where the free end-side region 51 is rubbed backward, so that the terminal portion 19 is caught by the leading end 51a of the free end-side region 51 by, thereby suppressing displacement in the pull-out direction.
- This can suppress loosening and coming-off of the ferrule terminal 17.
- the terminal portion 19 is sandwiched and hold by the leading end 51a of the free end-side region 51 and the pressing surface 33, thereby resulting in a restrained state where the terminal portion 19 is held.
- the terminal portion 19 has a width size of about 1.5 mm, a gap is formed between the leading end 51a of the free end-side region 51 and the pressing surface 33 by the width size of the terminal portion 19.
- FIG. 6 is a cross-sectional view of a state where insertion of the ferrule terminal has been completed.
- the leading end 19a of the terminal portion 19 is set so as to be spaced away from a bottom surface 47 of the inside of the housing 15.
- the collar portion 18 is about 6.0 mm in length
- the terminal portion 19 is about 8.0 mm in length, so that the ferrule terminal 17 used is about 14.0 mm in total length.
- FIG. 7 is a cross-sectional view of a state where a tool has been inserted.
- the tool insertion hole 25 seen from the front side in the depthwise direction, is arranged at a position overlapping with a region from a longitudinal other end side of the free end-side region 51 up to a longitudinal one end side of the first bent region 53.
- the tool insertion hole 25 is formed to be inclined by about 10 degrees to the depthwise direction so as to become closer to the terminal portion 19 toward the back side in the depthwise direction.
- the tool contact region 55 extends substantially in parallel with an axial line of the tool insertion hole 25.
- a tool 61 for example, a flathead screwdriver is used.
- an outer peripheral surface of the tool 61 slidingly contacts with a range from the longitudinal one end side of the first bent region 53 up to the tool contact region 55, and pushes the tool contact region 55 away to the outside of the terminal portion 19.
- a leading end of the tool 61 abuts with a range from the longitudinal other end side of the free end-side region 51 up to the second bent region 54, and pushes down the free end-side region 51.
- pushing the tool contact region 55 away to the outside of the terminal portion 19 or pushing down the free end-side region 51 narrows an opening degree of the tool contact region 55 with respect to the fixed end-side region 52, i.e., elastically deforms the plate spring 34 in the closing direction. This releases the engagement state between the leading end 51a of the free end-side region 51 and the terminal portion 19, whereby the terminal portion 19 is released from the restraint by the plate spring 34, thus enabling the ferrule terminal 17 to be pulled out.
- the angle ⁇ formed by the terminal portion 19 and the free end-side region 51 is set to be within 45 degrees ⁇ 2 degrees in the state where the leading end 19a of the terminal portion 19 reaches the leading end 51a of the free end-side region 51. Setting the angle as above leads to sharp reduction of reaction force received during insertion of the ferrule terminal 17 when the leading end 19a of the terminal portion 19 goes beyond the leading end 51a of the free end-side region 51. This results from significant reduction of friction coefficient ⁇ . In other words, from an operator's standpoint, since force received during insertion of the ferrule terminal 17 is suddenly reduced, the operator receives response, and easily perceives that shifting to the engagement state has surely been done.
- FIG. 8 is a graph depicting a relationship between insertion stroke and insertion force.
- the leading end 19a of the terminal portion 19 is in abutment with the plate surface of the free end-side region 51 of the plate spring 34, as illustrated in FIG. 4 .
- insertion force progressively increases due to reaction force caused by elastic deformation of the plate spring 34 and friction resistance caused by sliding of the leading end 19a of the terminal portion 19 on the plate surface of the free end-side region 51.
- the leading end 19a of the terminal portion 19 reaches the leading end 51a of the free end-side region 51, as illustrated in FIG. 5 .
- This is the time when the insertion force is at its peak.
- the angle ⁇ formed by the terminal portion 19 and the free end-side region 51 is set to be within 45 degrees ⁇ 2 degrees, the friction coefficient ⁇ significantly decreases as the ferrule terminal 17 is further inserted, whereby the insertion force sharply decreases.
- FIG. 9 is a cross-sectional view illustrating a plate spring structure of the comparative example.
- a plate spring 71 bent in a substantially V-shape is used.
- FIG. 9A is a cross-sectional view of a state before the ferrule terminal 17 is inserted.
- FIG. 9B is a cross-sectional view of a state where the terminal portion 19 is in abutment with the plate spring 71. In this state, an angle formed by the terminal portion 19 and a leading end of the plate spring 71 is about 45 degrees.
- FIG. 9C is a cross-sectional view of a state where the leading end of the terminal portion 19 has reached the leading end of the plate spring 71. In this state, the angle formed by the terminal portion 19 and the leading end of the plate spring 71 is about 30 degrees.
- FIG. 9D is a cross-sectional view of a state where insertion of the ferrule terminal 17 has been completed.
- FIG. 10 is a graph depicting a relationship between insertion stroke and insertion force in the comparative example.
- the leading end of the terminal portion 19 is in abutment with the leading end of the plate spring 71, as illustrated in FIG. 9B .
- insertion force progressively increases due to reaction force caused by elastic deformation of the plate spring 71 and friction resistance caused by sliding of the leading end of the terminal portion 19 on a plate surface of the plate spring 71.
- the angle ⁇ formed by the terminal portion 19 and the free end-side region 51 is set to be within 45 degrees ⁇ 2 degrees.
- the fixed end-side region 52, the first bent region 53, and the second bent region 54 are formed. Providing the second bent region 54 enables values of the angles ⁇ and ⁇ to be larger than in the structure of the comparative example, whereby it can be achieved that ⁇ is nearly equal to 45 degrees and ⁇ is nearly equal to 70 degrees.
- the first bent region 53 is set to have a curvature radius of twice or more than the plate thickness. This can suppress plastic deformation of the plate spring 34 and reduction of elastic force.
- providing the tool contact region 55 allows the plate spring 34 to be smoothly bent via the tool contact region 55 when the tool 61 is inserted, thereby enabling easy release of the engagement state with the terminal portion 19.
- the invention is not limited thereto, and a bare wire, whether a single wire or a stranded wire, may be used as it is.
- the invention is not limited thereto, and also applicable to a-contact relays and b-contact relays.
- the relay with the four pole contacts has been described, the invention is not limited thereto, and 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 17 inserted into the housing 15.
