The elastic member 24 urges the inner housing 21 in the outer housing 23 in the abutting direction of the terminal fitting 10 (the arrow X4 direction in FIG. 9).

  As shown in FIG. 8, the temporary locking mechanism 25 includes a temporary locking piece 251 formed integrally with the inner housing 21 and a temporary locking recess formed by recessing the upper and lower inner side surfaces 231 of the housing accommodating portion 23 a. 252.

  The temporary locking piece 251 includes an elastic piece 251a extending from the outer surface of the inner housing 21 along the inner side surface 231 of the housing accommodating portion 23a in the direction opposite to the abutting direction (the direction of arrow Y3 in FIG. 8), and the elastic piece 251a. A temporary locking projection 251b protruding from the tip of the piece 251a. The temporary locking protrusion 251b engages with the temporary locking recess 252 to stop the inner housing 21 at the temporary locking position.

  The temporary locking mechanism 25 described above is in a state in which the contact contact piece 12 is retracted into the outer housing 23 when the inner housing 21 is retracted in the housing accommodating portion 23 a against the elastic member 24. At the position, the temporary locking protrusion 251b engages with the temporary locking recess 252 to temporarily lock the inner housing 21 in the housing accommodating portion 23a.

  In the case of the present embodiment, the temporary locking release ridge 26 used to release the temporary locking state is formed on the elastic piece 251a of the temporary locking piece 251 so as to protrude into the gap S1. .

  The locking hole 43 is formed of a pair of left and right plate-like portions 42c. It is formed through 42d. When the inner housing 21 is temporarily released and the front holder 22 abuts the front end of the front holder 22 against the circuit board 30 as shown in FIGS. The main locking pieces 217 formed on both side surfaces are locked, and the inner housing 21 is fixed to the connector locking member 40.

  In the abutting connector board connection structure of the embodiment described above, until the abutting connector 20 is locked to the connector locking member 40 attached to the circuit board 30, as shown in FIG. The inner housing 21 can be temporarily locked by the temporary locking mechanism 25. When the inner housing 21 is temporarily locked, the contact-type terminal fitting 10 held by the inner housing 21 has the contact contact piece 12 at the tip of the terminal fitting 10 retracted into the outer housing 23. Is maintained. Therefore, it is possible to prevent the terminal fitting 10 from being deformed by avoiding collision of external equipment with the tip of the terminal fitting 10 when the butting connector 20 is transported.

  Further, in the abutting connector board connection structure according to the embodiment, when the abutting connector 20 is locked to the connector locking member 40 attached to the circuit board 30, the temporary connector provided in the connector locking member 40 is provided. The temporarily locked state of the inner housing 21 is released by a pair of upper and lower plate-like portions 42a and 42b which are locking release means. The inner housing 21 released from the temporarily locked state is pushed out in the abutting direction of the terminal fitting 10 by the urging force of the elastic member 24, and the abutting-type terminal fitting 10 held by the inner housing 21 is pushed. The tip is abutted against the contact pattern 31 on the surface of the circuit board 30, and the terminal fitting 10 in the abutting connector 20 is conductively connected to the contact pattern 31 on the surface of the circuit board 30.

Due to the impact, the oxide film existing on the surface of the contact contact piece 12 and the contact pattern 31 is destroyed and removed. Thereby, the resistance rise at the time of conduction | electrical_connection can be suppressed.

  That is, in the board connection structure of the butted connector according to one embodiment, the board connector that requires soldering work to the circuit board 30 is unnecessary. The contact pattern on the circuit board 30 can be easily connected.

  Moreover, in the board | substrate connection structure of the butting connector of one Embodiment, the temporary latch release means with which the connector latching member 40 is equipped is a simple board extended along the inner surface of the housing accommodating part 23a of the butting connector 20. Since the shape portions 42a and 42b are sufficient, the structure of the connector locking member 40 can be simplified.

  In addition, this invention is not limited to embodiment mentioned above, A deformation | transformation, improvement, etc. are possible suitably. In addition, the material, shape, dimensions, number, arrangement location, and the like of each component in the above-described embodiment are arbitrary and are not limited as long as the present invention can be achieved.

  For example, in the above-described embodiment, the tip of the front holder 22 is in contact with the circuit board 30 in the fully locked state, but the contact contact piece 12 of the terminal fitting 10 is firmly attached to the contact pattern 31 on the circuit board 30. The front holder 22 may be separated from the surface of the circuit board 30 as long as it is in elastic contact with the circuit board 30. In other words, in the final locking state, the front end of the abutting connector 20 (the front end of the front holder 22) may be positioned close to the surface of the circuit board 30.
