Fig. 5 a and Fig. 5 b are to show to regard for a pair of the first step that the first terminal and Second terminal in first embodiment are docked Figure, Fig. 6 a and Fig. 6 b is a pair of views of the second step for showing the first terminal and the Second terminal docking in first embodiment, figure 7a and Fig. 7 b are a pair of views of the 3rd step for showing the first terminal in first embodiment and Second terminal docking, and Fig. 8 a and Fig. 8 b are a pair of views of the 4th step for showing the first terminal and the Second terminal docking in first embodiment.In Fig. 5 a to Fig. 8 b In, Fig. 5 a, Fig. 6 a, Fig. 7 a, Fig. 8 a are a top view of the Second terminal for cutting off top plate portion and Fig. 5 b, Fig. 6 b, Fig. 7 b, Fig. 8 b point It is not the sectional view made from the line C-C of Fig. 5 a, Fig. 6 a, Fig. 7 a, Fig. 8 a.

By the heart yearn clamping connection portion 53a clamping connections of the first fixed part 53 and the heart yearn 92 of fixed wire 91 and by using sheath Insulating sheath on the heart yearn 92 of clamping connection portion 53b clamping connections and fixed wire 91, the first terminal 51 is installed on the terminal of a wire 91. The surface of the connection gasket that the second fixed part 153 is connected and is fixed on a substrate by using welding, Second terminal 151 is pacified Loaded on substrate (not shown).

As shown in Figure 1a, be held in together for the front end of the front end of the first terminal 51 and Second terminal 151 by operator, makes first Terminal 51 and/or Second terminal 151 are close to the terminal movable of the opposing party, and insert the first contact site 55 of the first terminal 51 To in the opening portion 157 of Second terminal 151.Because the entrance guidance part 157a extended from the front end of side plate 155b is arranged on out The front end of oral area 157 and the pair of entrance guidance part 157a so that the spacing between them is inclined with extending broadening forward, institute Can be freely insertable into the opening portion 157 of Second terminal 151 with the first contact site 55 of the first terminal 51.

When the lower section of the lower surface that the lower surface of the second fixed part 153 of Second terminal 151 is located at base plate 155a, when When the lower surface of the second fixed part 153 is connected to the surface of connection gasket, between the lower surface of base plate 155a and the surface of substrate Form a space.As a result, even if when Second terminal 151 is installed on a substrate, the first contact site 55 also can be inserted swimmingly Enter in opening portion 157.

When the first terminal 51 is moved along abutting direction opposite second terminal 151, first as shown in Fig. 5 a- Fig. 5 b, first The interior side contacts of the front-end edge 55f of contact site 55 and locking arm 156, particularly with the inner side of locking front side rake 156b Contact.After this, when the first terminal 51 is moved forward, rake 156b and locking on front side of the locking of each locking arm 156 Convex portion 156a is outwards shifted.As a result, as the first terminal 51 is moved forward, the first terminal 51 is subject to the elasticity of locking arm 156 to become The counteractive resistance of shape.

It is noted that as shown in Fig. 5 a- Fig. 5 b, when before the front-end edge 55f of the side plate 55b of the first contact site 55 and locking During the interior side contacts of inclined portion 156b, the front-end edge 55f of base plate 55a also not with the inclination plate portion of contact arm portion 155d 155d2 is contacted.Therefore, the first terminal 51 can advance without being come from by because of the reaction of the elastic deformation of contact arm portion 155d The resistance of contact arm portion 155d.

Then, when the first terminal 51 advances along the further opposite second terminal 151 of abutting direction, such as Fig. 6 a- Fig. 6 b institutes Show, the inclination plate portion 155d2 of the front-end edge 55f and contact arm portion 155d of the base plate 55a of the first contact site 55 is contacted.Afterwards, As the first terminal 51 advances, the front end of contact arm portion 155d shifts downwards.Therefore, as the first terminal 51 advances, first end Son 51 is subject to the counteractive resistance of contact arm portion 155d elastic deformations.

In the location point (point) shown in Fig. 6 a- Fig. 6 b, locking front side rake 156b and the locking of arm 156 are locked Convex portion 156a is outwards shifted, and locking convex portion 156a is contacted (in Fig. 6 a with the outer surface of the side plate 55b of the first contact site 55 In Fig. 7 a, for simplicity, locking convex portion 156a and side plate 55b is overlapped, but locking arm 156 actually elasticity becomes The medial extremity of shape and locking convex portion 156a is contacted with the outer surface of side plate 55b).Because at this moment before the locking of locking arm 156 Inclined portion 156b and locking convex portion 156a are not shifted further out, so the first contact site 55 is not by locking arm 156 Elastic deformation it is counteractive from locking arm 156 stop.

Then, when the first terminal 51 advances along the further opposite second terminal 151 of abutting direction, as shown in fig. 7, contact The front end of arm 155d shifts downwards, and contact end 155d3 positioned at the front end, is more specifically formed at contact end The second contact convex portion 155c on 155d3 is contacted with the lower surface of the base plate 55a of the first contact site 55.Because working as the first terminal The 51 end 155d3 of contact when having proceeded to this location point not further displacements and contact arm portion 155d does not become further Shape, so the first terminal 51 does not receive counteractive the stopping from contact arm portion 155d of the elastic deformation of contact arm portion 155d.

In the location point shown in Fig. 7 a- Fig. 7 b, locking front side rake 156b and the locking convex portion of each locking arm 156 156a has outwards been shifted and has been locked convex portion 156a and contacted with the outer surface of the side plate 55b of the first contact site 55.Now, even if The first terminal 51 is advanced further, and the first terminal 51 is also no longer influenced by coming for the reaction force of the elastic deformation for locking arm 156 From the stop of locking arm 156.

Then, as shown in Fig. 8 a- Fig. 8 b, when the first terminal 51 advances along the further opposite second terminal 151 of abutting direction When, the first contact site 55 inserts the second contact site 155 and has completed, and the docking of the first terminal 51 and Second terminal 151 is complete Into, and the front-end edge 55f of the first contact site 55 contacts with inner wall part 154.Therefore, the first terminal 51 is along abutting direction relative second Terminal 151 is positioned and can not be advanced further.

Additionally, the lock recess 56 for being formed at the side plate 55b of the first contact site 55 has reached the locking of locking arm 156 Convex portion 156a.As a result, the elasticity of shape of locking arm 156 is recovered and locking convex portion 156a enters in lock recess 56.So, lock Determine convex portion 156a and lock recess 56 is engaged with each other and locks.This makes the first terminal 51 and Second terminal 151 keep mated condition. It is noted that locking convex portion 156a is more specifically locked out the inner surface of rear side rake 156c and the front end of lock recess 56 Edge is contacted.As a result, the locked rear side rake 156c of side plate 55b are pressed towards inner wall part 154.Therefore, side plate 55b is by locking Seized on both sides by the arms before and after rear side rake 156c and inner wall part 154, and the first terminal 51 the stabilization of position opposite second terminal 151.

The elastic reaction of contact arm portion 155d causes contact end 155d3 specifically so that the second contact convex portion 155c is compressed The lower surface of the base plate 55a of the first contact site 55.In Fig. 5 a to Fig. 8 b, for convenience, the of excision Second terminal 151 The top plate portion 155e of two contact sites 155.However, in fact, top plate portion 155e is exist, and being formed at the upper of side plate 55b The first contact convex portion 55c of ora terminalis 55e is contacted with the lower surface of top plate portion 155e, thus prevents the first contact site 55 from moving upwards Position.Therefore, the second contact convex portion 155c reliably compresses the lower surface of the base plate 55a of the first contact site 55, and keeps and bottom The contact of plate portion 55a.

Because guiding convex portion 155g is located under just (directly) of heart yearn clamping connection portion 53a top and guiding convex portion 155g End is near to or in contact with the upper end of heart yearn clamping connection portion 53a, so being connected to the of the rear of the first contact site 55 of the first terminal 51 The displacement of the above-below direction of one fixed part 53 is limited by guiding convex portion 155g.Therefore, even if when the first fixed part 53 is upper and lower When being acted on by external force on direction, the posture of the first contact site 55 being inserted into the second contact site 155 keeps stabilization, and first Terminal 51 and Second terminal 151 keep reliable mated condition.

Additionally, the front-end edge 55f at least from the first contact site 55 of the first terminal 51 is to being connected to the first contact site 55 (the long range) on a large scale of the rear end of the heart yearn clamping connection portion 53a of first fixed part 53 at rear is housed in Second terminal 151 The second contact site 155 in.Therefore, though when the first terminal 51 or Second terminal 151 are subject to external force (such as vibrating) effect, Posture and position relationship between the first terminal 51 and Second terminal 151 maintain the original state (undisturbed), and maintain stabilization Contact condition.
