  However, if a clearance is provided between the female terminal and the female housing as in the prior art, when the wire harness receives the vibration of the vehicle, the vibration is transmitted to the female terminal, and the female terminal It vibrates with the male terminal on the side, and there is a problem that wear occurs at the contact portion between the female terminal and the male terminal. Such wear increases as the vibration increases, and the wear amount increases over a wide range.

  Note that the type in which the housing is fastened with a bolt to a predetermined position in the vehicle is strong against vibration, but the vehicle assembly workability of the wire harness is poor, and a work space must be secured.

  The subject of this invention is proposing the connector which can suppress the vibration of a female terminal and a male terminal.

  In order to achieve the above object, the invention described in claim 1 includes a male connector in which a pair of male terminals are provided in a male housing, and a female connector in which a pair of female terminals are provided in a female housing. Equipped with a male intermediate between the male terminals, a female intermediate between the female terminals, and by pushing the male intermediate into the female intermediate when connecting the male connector and female connector, The male side intermediate body and the female side intermediate body are characterized in that the force in the push-in direction is changed to the female terminal side to which the male terminal is fitted, and the female terminal is pressed against the male housing or the female housing.

  According to this, since the male side intermediate body and the female side intermediate body change the direction of pushing the male side intermediate body into the female side intermediate body to the female terminal side, the female terminal is pressed against the male housing or the female housing. be able to. Thereby, since the male terminal connected to the female terminal is also pressed against the female terminal, vibration of the male terminal and the female terminal can be suppressed, and as a result, wear of the contact portion between the terminals can be prevented.

  In this case, one of the male side intermediate body and the female side intermediate body is a flat plate, and the other is constituted by a block having a slit into which the flat plate is fitted, and the block is formed of an elastic material, and at least the slit is formed. It is preferable that the width of the inner portion is narrower than the thickness of the flat plate.

  According to this, since the flat plate fits into the slit, the slit is easily pushed and spread, so the force in the direction of pushing the male intermediate body into the female intermediate body is efficiently directed to the male terminal side and the female terminal side. Can be converted.

  The flat plate is preferably formed in a wedge shape in cross section.

  According to this, the slit width can be surely widened.

  Preferably, the block is accommodated in the female housing, and a projection is formed on the side surface of the block, and a step portion is formed on the side surface of the female terminal.

  According to this, the holding force of the female terminal can be increased by engaging the protrusion on the side surface of the block with the step on the side surface of the female terminal.

  ADVANTAGE OF THE INVENTION According to this invention, the connector which can suppress the vibration of a female terminal and a male terminal can be obtained.

  Inside the inner female housing 16, a pair of metal female terminals 17, 18 having a substantially cylindrical shape are arranged. The end of the inner female housing 16 on the front side (the front side in the direction perpendicular to the paper surface in FIG. 1) is flush with the end surface of the female housing main body 14 (see FIG. 3). Further, on the outer peripheral surfaces of the female terminals 17 and 18, bulged portions 17a and 18a as bulged portions are formed (FIG. 3).

  The inner female housing 16 has a front end bent to the female terminals 17 and 18 and covers a part of the front end face of the female terminals 17 and 18. That is, as shown in FIG. 1, when the female connector 11 is viewed from the front, the female terminals 17 and 18 can only be seen from their inner peripheral side end faces.

  A front holder 19 as a female intermediate is provided between the female terminals 17 and 18. As shown in FIG. 4, the front holder 19 is made of an elastic material (for example, synthetic resin), has a block shape, and has protrusions 20 on both side surfaces 19a. The protrusion 20 has a vertical surface 20 a perpendicular to the side surface 19 a of the front holder 19, an inclined surface 20 b inclined with respect to the side surface 19 a, and a vertical surface 20 c perpendicular to the side surface 19 a of the front holder 19. It has a trapezoidal shape. The inclined surface 20b is inclined in a direction approaching the side surface 19a toward the rear side of the front holder 19 (upwardly diagonally right in FIG. 4).

  Further, a slit 21 is formed in the center of the front surface 19b of the front holder 19 (a surface on the lower left side in FIG. 3) in the vertical direction from the upper surface 19c of the front holder 19 toward the bottom surface 19d. The slit 21 reaches the vicinity of the rear surface (surface on the upper right side in the figure) 19e of the front holder 19, and the tip portion 21a is formed in a round shape.

  As described above, the inner female housing 16 has its front end bent to the female terminals 17 and 18 side, and an opening is formed at the center of the bent portion. When the front holder 19 is assembled to the female connector 11, the front holder 19 is pushed between the female terminals 17 and 18 through the opening from the front side of the inner female housing 16. At this time, the protrusions 20 on both side surfaces 19a of the front holder 19 press the bulging portions 17a and 18a formed on the outer peripheral surfaces of the female terminals 17 and 18, respectively (at this time, the front holder 19 is in a direction in which the slit 21 is closed). It will be elastically deformed). Then, the front holder 19 that is pushed further into the back reaches the core member 22 (see FIG. 3) provided at the center of the inner female housing 16, with each protrusion 20 getting over the bulging portions 17 a and 18 a. When each protrusion 20 gets over the bulging portions 17 a and 18 a of the female terminals 17 and 18, the front holder 19 is firmly held by the bulging portions 17 a and 18 a and is prevented from falling off from the female connector 11.

  On the other hand, as shown in FIG. 2, the male connector 12 has a male housing 25. The male housing 25 has a rectangular tube-shaped male housing body 26 with four corners formed in a round shape, A male coupling portion 27 provided on the upper portion of the male housing body 26 is provided.

  A terminal support plate 28 is provided inside the male housing body 26, and a pair of substantially cylindrical male terminals 29, 30 are arranged on the terminal support plate 28. As shown in FIG. 3, the male terminals 29 and 30 are formed into a cylindrical male metal terminal body 29a and 30a, and a core material 29b made of synthetic resin and fitted into the male terminal bodies 29a and 30a. 30b. The core materials 29b and 30b form the tip portions of the male terminals 29 and 30, respectively.

  Further, as shown in FIG. 2, a tentacle prevention rib 31 as a male side intermediate body is provided between the male terminals 29 and 30. The ribs 31 for preventing tentacles are disposed to face the slits 21 formed in the front holder 19. The tentacle prevention rib 31 prevents the hand from touching the male terminals 29 and 30 and prevents a short circuit between the male terminals 29 and 30, and is formed of a synthetic resin. The tentacle-preventing rib 31 has an I-shaped longitudinal section, and the entire heel side is fixed to the terminal support plate 28 so as not to tilt toward the male terminal 29 side or the male terminal 30 side. That is, the tentacle prevention rib 31 is always perpendicular to the terminal support plate 28.

  In the above configuration, when the male connector 12 and the female connector 11 are connected to each other, the male housing body 26 enters between the female housing body 14 and the inner female housing 16 as shown in FIG. , 30 are fitted into the female terminals 17, 18, respectively. At the same time, the tentacle prevention rib 31 of the male connector 12 is pushed into the slit 21 formed in the front holder 19 of the female connector 11. Note that. At this time, the female coupling portion 15 of the female connector 11 and the male coupling portion 27 of the male connector 12 are coupled to each other.

  Here, the width H of the slit 21 (see FIG. 4) is set to be the same as the plate thickness of the tentacle prevention rib 31 or narrower than the plate thickness. Then, the tentacle prevention rib 31 and the front holder 19 change the direction of pushing the tentacle prevention rib 31 into the slit 21 to the male terminals 29 and 30 side and the female terminals 17 and 18 side. That is, since the width H of the slit 21 is equal to or smaller than the plate thickness of the tentacle prevention rib 31, when the tentacle prevention rib 31 is pushed into the slit 21, the width of the slit 21 increases. Thereby, the front holder 19 spreads to the male terminals 29 and 30 side and the female terminals 17 and 18 side. Therefore, the female terminal 17 fitted with the male terminal 29 and the female terminal 18 fitted with the male terminal 30 can be pressed against the inner female housing 16 (that is, the female housing 13), respectively.

  3, reference numerals 32 and 33 are female cables connected to the female terminals 17 and 18, respectively, and reference numerals 34 and 35 are male cables connected to the male terminals 29 and 30, respectively.

  Here, if the tentacle-preventing rib 31 is wedge-shaped, the force for pushing the tentacle-preventing rib 31 into the slit 21 is applied to the female terminal 17 side to which the male terminal 29 is fitted and the female to which the male terminal 30 is fitted. The direction can be efficiently changed to the terminal 18 side. The tentacle prevention rib 31 may have a straight shape, and the slit 21 of the front holder 19 may have a V-shaped cross section (transverse cross section).

  Thus, if the female terminal 17 fitted with the male terminal 29 and the female terminal 18 fitted with the male terminal 30 are pressed against the female housing 13 respectively, the female terminals 17 and 18 and the female housing 13 In addition, the male terminals 29 and 30 fitted to the female terminals 17 and 18 are pressed against the female terminals 17 and 18, respectively, and the adhesion between the terminals is enhanced. Therefore, even if it receives vibration from a vehicle, since vibration of female terminals 17 and 18 and male terminals 29 and 30 can be controlled, as a result, wear of a contact portion between terminals can be suppressed and electrical conductivity between terminals can be suppressed. Can be avoided.

  In the present embodiment, since the front holder 19 holds the female terminals 17 and 18, the holding force of the female terminals 17 and 18 can be increased by holding the female terminals 17 and 18 together with the lance. Therefore, a connector can be reduced in size by reducing or omitting an existing lance.

  In this embodiment, since the male housing main body 26 is structured to enter between the female housing main body 14 and the inner female housing 16, the female terminal 17 and the male terminal 30 with the male terminal 29 fitted are fitted. Each of the female terminals 18 presses the inner female housing 16. For example, if the male housing body 26 enters the inner female housing 16, the female terminal 17 fitted with the male terminal 29 is used. The female terminal 18 fitted with the male terminal 30 can be configured to be pressed against the male housing body 26 (male housing 25). Further, if the front holder 19 is structured to be accommodated in the male housing body 26, the female terminal 17 fitted with the male terminal 29 and the female terminal 18 fitted with the male terminal 30 are respectively connected to the male housing body 26. It can also be pressed against.

  In the above configuration, the front holder 19 is provided on the female connector 11, and the ribs 31 for preventing tentacles are provided on the male connector 12, but these are reversed, and the ribs 31 for preventing tentacles are provided on the female connector 11. The mold connector 12 may be provided with a front holder 19.
