  • FIG. 16 shows a state in which the first connector 16 and the second connector 202 constituting the joint connector 200 described above are connected and locked to each other, and in this case, the first connector 16 is the first embodiment. The same thing as the 1st connector 16 which constitutes joint connector 10 concerning a form of this is used.
  • FIG. 17 is a cross-sectional view of the second connector 202 cut substantially parallel to the width direction at a substantially central portion of the height dimension.
  • the second connector 202 has a third cavity 204 penetrating along the longitudinal direction (directions of arrows A1 and A2) of the second housing 218, and holds the bus bar 208 near one end of the third cavity 204.
  • a possible holding block 210 is provided.
  • the third cavity 204 is formed in a rectangular shape in cross section corresponding to the cross sectional shape of the second housing 218.
  • the holding block 210 is integrally formed with the second housing 218 and has a through hole 212 capable of holding the terminal portions 216 a and 216 b of the bus bar 208.
  • the connection portion 214 of the bus bar 208 is disposed on one end side (direction of arrow A1) of the second housing 218 with respect to the holding block 210, and the tip end of the terminal portions 216a and 216b is the same as that of the second housing 218. It arrange
  • the seal member 206 is attached to the inside of the third cavity 204 so as to cover the holding block 210 from one end side (in the direction of arrow A1) of the second housing 218, and the terminal portion 216 a of the bus bar 208 from the end of the seal member 206. , Part of 216b is protruding. That is, most of the bus bar 208 including the connection portion 214 is covered by the seal member 206, and the bus bar 208 is more firmly fixed to the holding block 210 by the seal member 206. That is, the third cavity 204 functions as a recess in which the seal member 206 is mounted.
  • connection terminals 14 are connected to the terminal portions 216 a and 216 b of the bus bar 208, respectively. Thereby, the airtightness between the first housing 20 and the second housing 218 is maintained.
  • the joint connector 200 it is possible to prevent the entry of moisture into the inside of the first and second connectors 16 and 202 through the flexible cable 12, and the first connector 16 and the second connector Moisture entering from the connection portion with 202 can also be reliably blocked by the seal member 206 extended to a position abutting on one end of the first connector 16. As a result, the waterproof function of the joint connector 200 can be further enhanced.
  • both ends of the second connector 202 can be obtained by using the bus bar not having the connection portion 214 but having the terminal portions at both ends. It is good also as composition which connects the separate 1st connector 16 from a part side, respectively.
  • a seal member is provided in the vicinity of the holding block 210. In other words, the seal member is disposed between one first connector 16 and the other first connector 16. Therefore, the movement of water between one first connector 16 and the other first connector 16 through the inside of the second connector 202 is reliably prevented by the seal member.
  • the joint connector according to the present invention is not limited to the above-described embodiment, and it goes without saying that various configurations can be adopted without departing from the scope of the present invention.
