  The spacer storage chamber 111c is a space that is recessed from the upper surface of the housing body 111 in the height direction of the housing body 111 (in the direction of arrow Z1 in FIG. 18). The height direction of the housing body 111 is a direction orthogonal to the fitting direction between the connector housings. Therefore, the spacer storage chamber 111c is a space that is recessed in a direction orthogonal to the fitting direction of the connector housings.

  In the spacer storage chamber 111c, as shown in FIG. 18, a temporary locking portion 111d for temporarily locking the terminal confirmation spacer 112 at the temporary locking position and the terminal confirmation spacer 112 are fixed at the final locking position. And a main locking portion 111e.

  The temporary locking portion 111d engages with the temporary locking protrusion 112a of the terminal confirmation spacer 112 when the terminal confirmation spacer 112 is inserted into the spacer storage chamber 111c along the arrow Z1 direction in FIG. Thus, the terminal confirmation spacer 112 is prevented from coming off at the temporary locking position. The temporary locking position of the terminal confirmation spacer 112 is a position where the contact surface 112b of the temporary locking projection 112a contacts the contact surface 111f of the temporary locking portion 111d.

The locking projection 112i is a portion that engages with the temporary locking portion 111d in the spacer storage chamber 111c, and a contact surface 112b that contacts the contact surface 111f of the temporary locking portion 111d is formed.

  In the middle of the terminal confirmation spacer 112 reaching the temporary locking position, the temporary locking projection 112a is bent temporarily in the direction of the arrow X2 in FIG. It rides on the part 111d. When the terminal confirmation spacer 112 reaches the temporary locking position, the locking projection 112i gets over the temporary locking portion 111d, and the locking projection 112i is engaged with the temporary locking portion 111d by the elastic restoring force of the elastic piece 112h. Combined state. Due to the engagement between the locking protrusion 112i and the temporary locking portion 111d, the terminal confirmation spacer 112 is temporarily locked at the temporary locking position.

  The terminal confirming spacer 112 temporarily fixed at the temporary locking position is configured such that the contact direction 112b of the locking protrusion 112i contacts the contact surface 111f of the temporary locking portion 111d, so that the terminal checking spacer 112 is removed. Movement to is regulated. Further, the terminal confirmation spacer 112 moves to the main locking position side when the locking protrusion 112m of the main locking protrusion 112c is caught by the raised portion 111h formed in front of the main locking portion 111e. Is regulated.

  As shown in FIG. 18, the main locking projection 112c extends along the direction in which the terminal confirmation spacer 112 is inserted into the spacer storage chamber 111c (in the direction of arrow Z1 in FIG. 18), and both ends are side wall portions. The elastic piece 112k of the both-ends beam shape connected to 112e and the latching protrusion 112m which protruded from the intermediate part of the longitudinal direction of this elastic piece 112k are provided. The locking protrusion 112m is a mountain-shaped protrusion that engages with the main locking portion 111e in the spacer storage chamber 111c.

  In the middle of the terminal confirmation spacer 112 reaching the final locking position from the temporary locking position, the main locking protrusion 112c is bent by the elastic piece 112k in the direction of the arrow X3 in FIG. 112m rides on the raised portion 111h. When the terminal confirmation spacer 112 reaches the main locking position, the locking projection 112m gets over the raised portion 111h, and the locking projection 112m engages with the main locking portion 111e by the elastic restoring force of the elastic piece 112k. It becomes a state.

  By the engagement between the locking protrusion 112m and the main locking portion 111e, the movement of the terminal confirmation spacer 112 is restricted in both the arrow Z1 direction and the direction opposite to the arrow Z1 in FIG. It will be in the state fixed to this latching position.

  The terminal confirmation spacer 112 described above can be moved from the temporary locking position to the final locking position along the direction orthogonal to the fitting direction of the connector housings by being inserted into the spacer housing chamber 111c. The housing body 111 is assembled.

  As shown in FIG. 17, the intermediate portion 112f of the terminal confirmation spacer 112 includes a terminal insertion hole 112p and a terminal locking portion 112q.

  The terminal insertion hole 112p is a hole through which the female terminal fitting 113 can be inserted.

In addition, as shown in FIG. 17, the terminal confirmation spacer in a state where the insertion of the female terminal fitting 113 into the terminal accommodating chamber 111a reaches the specified position and the female terminal fitting 113 is locked by the terminal locking lance 111b. When 112 is moved to the main locking position, the terminal locking portion 112q engages with the spacer step 113d of the female terminal fitting 113 to lock the female terminal fitting 113. In this state, the female terminal fitting 113 is doubly locked by the terminal locking lance 111b and the terminal confirmation spacer 112.

  On the other hand, in the poorly fitting state where the position of the female terminal fitting 113 inserted into the terminal accommodating chamber 111a has not reached the specified position (in other words, the position of the female terminal fitting 113 is incorrect), the temporary locking position When the terminal confirmation spacer 112 located at the position is moved to the final locking position, the terminal locking portion 112q interferes with the peripheral portion of the spacer step 113d, and the terminal confirmation spacer 112 is finally locked. It cannot be moved to a position.

  That is, the terminal confirmation spacer 112 is a component that can confirm the suitability of the position of the female terminal fitting 113 in the terminal accommodating chamber 111a depending on whether or not it can be pushed into the final locking position. Accordingly, when the terminal confirmation spacer 112 cannot be pushed into the final locking position, it is determined that the female terminal fitting 113 is in a poor fitting state, and the female terminal fitting 113 with a poor fitting is attached again and the female terminal fitting 113 is reattached. By correcting the terminal fitting 113 to an appropriate position, it is possible to prevent oversight of poor fitting of the female terminal fitting 113.

First, the first connector housing 110 has the terminal confirmation spacer 112 assembled to the housing main body 111 positioned at the temporary locking position, and after fitting the female terminal fitting 113 to each terminal accommodating chamber 111a, An operation of pushing the confirmation spacer 112 into the final locking position is performed to confirm that the female terminal fittings 113 fitted to the housing body 111 are not poorly fitted.

  Next, the first connector housing 110 in which the fitting state of the female terminal fitting 113 is confirmed is fitted into each housing fitting chamber 121 of the second connector housing 120, so that the female held by the first connector housing 110. A state in which the terminal fittings 113 are connected to each other is obtained.

  By the way, in the connector of patent document 1 demonstrated above, and the connector 100 shown in FIGS. 15-21, it is for terminal confirmation with which the 1st connector housing 110 was equipped before fitting connector housings mutually. An operation of pushing the spacer 112 into the final locking position is necessary. Therefore, due to this operation, an operation process at the time of assembling the connector increases, and it may be difficult to improve the productivity of the connector 100.

  Accordingly, an object of the present invention is to solve the above-mentioned problems, and for terminal confirmation by an operation of fitting the connector housings together without performing a direct operation of moving the terminal confirmation spacer to the final locking position. By moving the spacer to the final locking position, you can check the suitability of the position of the terminal fittings mounted on the first connector housing, reducing the operation process when assembling the connector, and improving the connector productivity. The object is to provide a connector that can be improved.

The above-described object of the present invention is achieved by the following configuration.
(1) A housing body having a terminal accommodating chamber extending along the mating direction between the connector housings, and movable from the temporary latching position to the final latching position along a direction orthogonal to the mating direction. A first connector housing comprising: a terminal confirmation spacer assembled to the housing body and capable of confirming whether or not the position of the terminal fitting in the terminal accommodating chamber is appropriate depending on whether or not the main body is pushed into the main locking position. ,
A second connector housing comprising a plurality of housing fitting chambers to which the first connector housing is mounted;
A connector with
A spacer exposing groove formed in the outer wall of the housing body by cutting out along the fitting direction;

This eliminates the need for a single operation to move the terminal confirmation spacer to the final locking position. Therefore, the operation process at the time of connector assembly can be reduced and the productivity of the connector can be improved.

  According to the configuration of (2) above, the spacer biasing rib is integrally formed on the partition wall of the housing fitting chamber, so that high strength can be ensured for the spacer biasing rib.

  According to the configuration of (3) above, the spacer urging rib, the spacer exposing groove, and the driving sliding surface are provided on each of the opposing side surfaces of the housing fitting chamber and the first connector housing. ing. Therefore, when trying to fit the first connector housing into the housing fitting chamber of the second connector housing in a direction different from the normal direction, the position of the spacer exposure groove is aligned with the spacer biasing rib of the housing fitting chamber. Are arranged on the opposite side, and the spacer urging rib interferes with the side surface of the first connector housing, and the connector housings cannot be engaged with each other. Therefore, erroneous assembly of the first connector housing can be prevented.

  According to the configuration of (4) above, the driving sliding surface of the terminal confirmation spacer protrudes in the spacer exposure groove of the housing body and does not protrude outwardly from the one outer wall surface of the housing body.

  Therefore, the protruding length of the driving sliding surface does not increase the width of the first connector housing, and the connector can be made smaller.

  According to the configuration of (5) above, since the first connector housing is a multipolar connector, it is held by the first connector housing by moving the terminal confirmation spacer assembled to the first connector housing to the final locking position. The suitability of the positions of the plurality of terminal fittings can be detected at once, and the plurality of terminal fittings can be double locked together.

  According to the configuration of (6) above, it is a simple configuration in which at least one of the spacer urging rib and the abutting surface of the driving sliding surface which are in contact with each other in the mating direction between the connector housings is an inclined surface, A biasing force toward the main locking position can be applied to the spacer, and a mechanism for moving the terminal confirmation spacer to the main locking position by fitting the connector housings can be realized with a simple structure.

  According to the connector of the present invention, it is possible to confirm the suitability of the position of the terminal fitting mounted on the first connector housing without performing a direct operation of moving the terminal confirmation spacer to the final locking position. It is possible to improve the productivity of the connector by reducing the operation process at the time of assembling the connector.
