[Operation of this embodiment]
In order to insert and connect the female terminal 1 to each terminal receiving hole 3 of the connector housing 1, the terminal end of the terminal body 10 is held with the female terminal 1 from the one end opening 3 a to the inside of the terminal receiving hole 3. Insert into and push in as it is. Then, the bottom surface of the outer bottom wall 13a of the terminal body 10 is slidably contacted along the inner bottom surface of the bottom wall 2a of the terminal receiving hole 2, that is, the notch surface 3c, the tapered surface 3d, and the flat surface 3e, and the both stabilizers. The outer surfaces 20 and 20 are inserted into the female terminal 1 while sliding on the inner surfaces 3f and 3f of the terminal receiving hole 3, respectively.

  When the lower surface of the bent base portion 19a of the contact spring 19 of the terminal body 10 slides forward while riding on the inclined lower surface 4d of the lance portion 4, the distal end portion 4b of the lance portion 4 is fixed to the fixed base end. Using the portion 4a as a fulcrum, it is elastically deformed upward in the figure and enters the space portion 5.

  Thereafter, when the front end hole edge 18a of the lance hole 18 reaches the locking groove 4c of the lance part 4, the tip part 4b is deformed downward by the elastic restoring force of the lance part 4, and the front end hole edge 18a is formed. The locking groove 4c is locked. Thereby, the movement of the female terminal 1 in the pull-out direction is restricted.

  On the other hand, as shown in FIGS. 3 and 4, the stabilizers 20, 20 have a distal end until the terminal body 10 is locked to the lance portion 4 via the lance hole 18 as described above. The front edges of the portions 20b and 20b start to contact the leading edges of the guide surfaces 8a and 8a of the projections 8 and 8, and are guided by the guide surfaces 8a and 8a as they are. Move to maximum convex surface.

  At this time, the stabilizers 20 and 20 are gradually given inward reaction forces from the guide surfaces 8a and 8a and the maximum convex surface, and each base 20a and 20a is used as a fulcrum as shown in FIG. The tip portions 20b and 20b are elastically deformed inward. Accordingly, the female terminal 1 is held by the stabilizers 20 and 20 from the lateral direction with respect to the terminal receiving hole 3.

  After each female terminal 1 is inserted and fixed in each terminal receiving hole 3, the male terminal 16 is connected to the other end opening 3b of the terminal receiving hole 3 and the female terminal 1 from the tip 16a as shown in FIG. When inserted into the terminal body 10 through the opening 10a and pushed into the inside against the elastic reaction force of the tip 19b of the contact spring 19, the upper and lower surfaces of the tip 16a of the male terminal 16 are moved to the tip. The two-step curved lower surface 19c of 19b and the two contact beads 17 of the inner bottom wall portion 13b are held in a sandwiched state by elastic force.

  As described above, in the present embodiment, the female terminal 1 can be reliably restricted from moving in the removal direction by the locking action of the lance portion 4 with respect to the front end hole edge 18a of the lance hole 18, in particular, Since the female terminal 1 is elastically held from the lateral direction in the terminal accommodating hole 3 by the pair of stabilizers 20, 20, for example, when vibration of the vehicle is transmitted to the female terminal 1 via the connector housing 2, The vibrations are absorbed by both the stabilizers 20, 20, and vibration transmission to the female terminal 1 is suppressed.

  As a result, it is possible to sufficiently suppress the deterioration caused by the displacement of the contact position due to the slight vibration between the female terminal 1 and the male terminal 16 caused by external factors such as the vibration of the vehicle and the change in ambient temperature. become.

  In addition, in the present embodiment, vibrations are suppressed by using the existing stabilizers 20 and 20 of the female terminal 1, that is, the notches 21 and 22 are formed in the stabilizers 20 and 20, and the spring members are configured. At the same time, since the vibration is suppressed by using the protrusions 8 and 8 formed integrally with the inner side surfaces 3f and 3f of the terminal accommodating hole 3, the number of parts is not increased. Therefore, it is possible to reduce the manufacturing cost and suppress the reduction of the manufacturing work efficiency.

  Further, since the one second notch 22 has a third notch 22a extending from the lower edge, each stabilizer for the projections 8 and 8 is determined by the length of the third notch 22a. The spring reaction force of 20, 20 can be adjusted appropriately.

In the present embodiment, the protrusions 8 and 8 are provided in the terminal receiving hole 3 so as to apply a spring reaction force to the stabilizers 20 and 20, but outwardly on the outer surfaces of the stabilizers 20 and 20. It is also possible to apply a spring reaction force to each of the stabilizers 20 and 20 by providing facing protrusions integrally and bringing the protrusions into contact with the opposing inner side surfaces 3f and 3f of the terminal receiving hole 3. is there. In this case, since each said protrusion can be utilized as a reinforcement part of each stabilizer 20 and 20, it is further effective.
[Second Embodiment]
8 and 9 show a second embodiment, in which the notches 21 and 22 with respect to the base portions 20a and 20a of the stabilizers 20 and 20 are abolished so that only a normal guiding function is provided, and both side walls of the terminal body 10 of the female terminal 1 are provided. A plurality of elastic pieces 23, 24, 25 as spring members are provided in front and rear positions of the portions 14, 14 and in the vicinity of the lance hole 18 of the upper wall portion 15.

  Specifically, the first elastic pieces 23, 23 on the front side are formed in a substantially rectangular shape long in the front-rear direction by the inverted U-shaped cut portions 26, 26 on the both side wall portions 14, 14, and the remaining cut portion The tip portions 23b and 23b are formed so as to be elastically deformable inward and outward with the base portions 23a and 23a of the portion as fulcrums.

  Further, a pair of protrusions 27 are provided on the outer surfaces of the tip portions 23b and 23b of the first elastic pieces 23 and 23, respectively. The protrusions 27 and 27 are formed together by embossing when the female terminal 1 is press-molded, and are formed in a convex shape that is long in the vertical direction.

  The second elastic pieces 24, 24 on the rear side have the same shape as the first elastic pieces 23, 23, and are substantially rectangular long in the front-rear direction by the U-shaped cut portions 28, 28 on the side wall portions 14, 14. The tip portions 24b and 24b are formed in a shape so as to be elastically deformable inward and outward with the base portions 24a and 24a of the remaining cut portions as fulcrums.

  Similarly, a pair of protrusions 29 and 29 are provided on the outer surfaces of the tip portions 24b and 24b of the second elastic pieces 24 and 24, respectively. The protrusions 29 and 29 are also formed together by embossing when the female terminal 1 is press-molded, and are formed in a convex shape that is long in the vertical direction.

  One third elastic piece 25 on the upper wall portion 15 side has the same shape as the second elastic piece 24 and is formed in a substantially rectangular shape that is long in the front-rear direction by a U-shaped cut portion 30 in the upper wall portion 15. Thus, the distal end portion 25b is formed to be elastically deformable in the vertical direction with the base portion 25a of the remaining cut portion as a fulcrum.

  Similarly, a pair of protrusions 31 are provided on the outer surface of the tip 25b of the third elastic piece 25. The protrusion 31 is also formed together by embossing when the female terminal 1 is press-molded, and is formed in a convex shape that is long in the vertical direction.

  Therefore, according to this embodiment, when the female terminal 1 is inserted into the inside from the one end opening 3a of the terminal accommodating chamber 3, first, the first elastic pieces 23, 23 are elastically contacted with the inner side surfaces 3f and 3f of the terminal accommodating chamber 3, and the distal end portions 23b and 23b of the first elastic pieces 23 and 23 are springed inward with respect to the base portions 23a and 23a. Elastically deforms with reaction force. Subsequently, the distal end portions 24b, 24b of the second elastic pieces 24, 24 are spring reaction forces inward from each other with the base portions 24a, 24a serving as fulcrums via the projections 29, 29 elastically contacting the inner side surfaces 3f, 3f. The third elastic piece 25 also moves downward with the base portion 25a serving as a fulcrum through the protrusion 31 elastically contacting the lower surface of the upper wall portion 2c, that is, the ceiling surface 3h of the terminal accommodating hole 3. Elastically deforms with spring reaction force.

  Therefore, the female terminal 1 is laterally moved by the spring reaction force of the first to third elastic pieces 23 to 25 in a state where the female terminal 1 is locked and fixed in the terminal receiving hole 3 via the lance portion 4 and the lance hole 18. In this manner, the terminal is held in the terminal receiving hole 3 from above and below.

  For this reason, when vehicle vibration or the like is transmitted to the female terminal 1 via the connector housing 2, the vibration is absorbed by the first to third elastic pieces 23 to 25, and the vibration of the female terminal 1 is effectively suppressed. can do.

  As a result, it is possible to sufficiently suppress the deterioration caused by the displacement of the contact position due to the slight vibration between the female terminal 1 and the male terminal 16 caused by external factors such as the vibration of the vehicle and the change in ambient temperature. become.

  In particular, in this embodiment, the first and second elastic pieces 23 and 24 can absorb lateral vibrations with respect to the female terminal 1, and the third elastic piece 25 can also absorb vertical vibrations. Therefore, the further vibration suppression effect of the female terminal 1 is obtained. As a result, it is possible to further suppress deterioration due to the displacement of the contact position due to the slight vibration between the female terminal 1 and the male terminal 16.

  Also, in this embodiment, the elastic pieces 23 to 25 are formed by using a part of the outer wall of the female terminal 1, so that there is no increase in the number of parts. In particular, as in the first embodiment, the terminal receiving hole Since it is not necessary to provide the projections 8 and 8 on the inner side surfaces 3f and 3f of the third connector 3, the existing connector housing 2 can be used. Therefore, an increase in manufacturing cost can also be suppressed in this respect.

  In the present embodiment, in addition to the third elastic piece 25 provided on the upper wall portion 15 of the female terminal 1, a second structure having the same structure is provided at a position corresponding to the third elastic piece 25 of the lower bottom wall portion 13 b. It is also possible to provide four elastic pieces.

  In this way, the elastic holding in the vertical direction in the terminal accommodating hole 3 with respect to the female terminal 1 becomes more effective.

  The present invention is not limited to the configuration of the above-described embodiment. For example, the structure of the spring member can be further changed. For example, the elastic piece can be formed in a triangular shape or a semicircular shape. Is possible.

  Further, it is possible to provide a protrusion or the like that engages with the engaging groove 4 c of the lance portion 4 at the front end hole edge 18 a of the lance hole 18.
