Since the mating side connector 50 is the same as the first connector 10 turned upside down, detailed description thereof will be omitted. The mating connector 50 may have a structure (shape) different from that of the first connector 10.

[Temporary assembly of connector device]
Next, the temporary assembly of the connector device 2 will be described with reference to FIGS. 8 to 10. 8, 9 and 10 are a VIII-VIII sectional view, an IX-IX sectional view and an XX sectional view of FIG. 5 when FIG. 5 shows a connector device. Here, as an example, a procedure for the operator to temporarily assemble the connector device 2 will be described. The connector device 2 may be delivered to a customer (another manufacturer who mounts the connector device 2 on the substrate 6 or the like) in a state of being temporarily assembled by the manufacturer, for example. In the following description, the description will continue with focus on one first terminal 21 and one second terminal 41.

As shown in FIG. 8, the operator relatively fits the first connector 10 (first housing 11) into the lower fitting recess 33 of the second housing 31. In the process of fitting the first connector 10 into the lower fitting recess 33, the sub-claw side contact surface 36C of the pair of sub-claw claws 36B comes into contact with the chamfered portion 15A of the first housing 11 (sub-claw convex portion 15). Since it moves while moving, the pair of sublock arms 36A elastically deform outward so as to separate from each other. When each subblock claw 36B gets over the subblock convex portion 15, each subblock arm 36A is restored by its own elastic force, and each subblock claw 36B is slidably fitted into the subblock groove 14. Further, each subblock claw 36B engages with the subblock convex portion 15 from the lower side (downstream side in the connection direction).

On the other hand, as shown in FIG. 9, each main lock claw 37B is slidably fitted in the upstream lock groove 17U (main lock groove 17) and hits the main lock convex portion 18 from the upper side (upstream side in the connection direction). I'm in contact. That is, the main claw-side contact surface 37C of each main lock claw 37B is in contact with the main convex-side contact surface 18A of the main lock convex portion 18. It should be noted that each main lock claw 37B is only in contact with the main lock convex portion 18 and is not engaged.

With the above, the temporary assembly of the connector device 2 is completed. As shown in FIGS. 8 and 9, in the state where the temporary assembly is completed, the second connector 30 engages each first sublock portion 13 with each second subblock portion 36, and each first main. It is held by the first connector 10 at the preset position P1 in which the lock portion 16 and each of the second main lock portions 37 are disengaged. In this state, the upper portion of the first connector 10 is fitted into the lower fitting recess 33, and the lower portion of the first connector 10 is exposed. The upper surface of the first housing 11 faces the lower surface of the intermediate main body 34 of the second housing 31 with a space in between.

Further, as shown in FIG. 10, the first terminal 21 and the second terminal 41 are separated from each other in a state where the second connector 30 is held at the preset position P1. That is, the second terminal 41 is not in contact with the first terminal 21, and the first terminal 21 and the second terminal 41 are not elastically deformed from each other. In other words, the first terminal 21 and the second terminal 41 are not loaded by contact with each other. To be precise, the lower end of the second outer terminal 43 (second outer lower contact portion 43C) of the second terminal 41 is lightly in contact with the tapered portion 12A of the first housing 11 so as not to be elastically deformed. In this specification, "a state in which the connector device 2 is temporarily assembled" or "a state in which the second connector 30 is held by the first connector 10 at the preset position P1" is expressed as a "preset state" or the like. There is also.

[How to mount the connector device on the board]
Next, a method of mounting the connector device 2 on the board 6 (board mounting method) will be described with reference to FIGS. 10 to 13. FIG. 11 is a cross-sectional view when the connector device shown in FIG. 8 is in the set state. FIG. 12 is a cross-sectional view of the connector device shown in FIG. 9 in the set state. FIG. 13 is a cross-sectional view when the connector device shown in FIG. 10 is in the set state.

<First step>
Conventionally, the first connector 10 (first terminal 21) is soldered to the substrate 6, and then the second connector 30 is attached to the first connector 10. On the other hand, in the first step of the board mounting method according to the present embodiment, the first terminal 21 is soldered to the board 6 with the temporarily assembled connector device 2 arranged on the board 6.

First, as the first step, the connector device 2 in which the second connector 30 is held in the first connector 10 at the preset position P1 (in the preset state) is arranged on the substrate 6 coated with cream solder (see FIG. 10). ). The first center fixing portion 22A and the first outer fixing portion 23A of the first terminal 21 come into contact with the substrate 6 via cream solder. After arranging the first connector 10 on the substrate 6, the second connector 30 may be held by the first connector 10. That is, the connector device 2 may be temporarily assembled after the first connector 10 is arranged on the substrate 6.

Subsequently, the substrate 6 on which the connector device 2 is placed is passed through a reflow furnace to heat and melt the cream solder on the substrate 6, and the first terminal 21 is soldered to the substrate 6. As described above, the first connector 10 is fixed to the substrate 6 via the first terminal 21.

<Second step>
Next, as a second step, the second connector 30 held by the first connector 10 is moved from the preset position P1 to the set position P2. Specifically, the operator pushes the second connector 30 downward (first connector 10). As shown in FIG. 12, in the process of pushing down the second connector 30, the main claw side contact surface 37C of the pair of main lock claws 37B moves while contacting the main convex side contact surface 18A of the main lock convex portion 18. Therefore, the pair of main lock arms 37A are elastically deformed outward so as to be separated from each other. When each main lock claw 37B gets over the main lock convex portion 18, each main lock arm 37A is restored by its own elastic force. Then, each main lock claw 37B is slidably fitted in the downstream lock groove 17D and engages with the main lock convex portion 18 from the lower side (downstream side in the connection direction).

On the other hand, as shown in FIG. 11, each subblock claw 36B moves downward along the subblock groove 14 and is separated downward (downstream side in the connection direction) from the subblock convex portion 15.

With the above, the board mounting of the connector device 2 is completed. In this state, as shown in FIGS. 11 and 12, the second connector 30 disengages the first sublock portion 13 and the second subblock portion 36, and the first main lock portion 16 and the second connector 30 are disengaged. 2 It is held by the first connector 10 at the set position P2 in which the main lock portion 37 is engaged. In this state, substantially the entire first connector 10 is fitted in the lower fitting recess 33 and hidden inside the lower fitting recess 33. The upper surface of the first housing 11 is in contact with the lower surface of the intermediate main body 34 of the second housing 31, which restricts the pushing down of the second connector 30. The force (resistive force) against the pulling out of the second connector 30 when the main lock claw 37B is engaged with the main lock convex portion 18 is the resistance when the sublock claw 36B is engaged with the sublock convex portion 15. It is set larger than the force. When the second connector 30 moves to the set position P2, the second connector 30 cannot be easily removed from the first connector 10.

Further, as shown in FIG. 13, in a state where the second connector 30 is held at the set position P2, the first terminal 21 and the second terminal 41 are in contact with each other with elastic force. To be precise, the second center lower contact portion 42C of the second center terminal 42 is inserted between the bifurcated first center terminals 22, and is elastically sandwiched between the bifurcated first center terminals 22. There is. The second outer lower contact portion 43C of the second outer terminal 43 is inserted into the inside of the first outer terminal 23 with a slight diameter reduction, and is in contact with the inner peripheral surface of the first outer terminal 23 with elastic force. In this state, the first terminal 21 and the second terminal 41 are in contact with each other at a normal contact pressure set in advance to ensure normal energization. That is, the first terminal 21 and the second terminal 41 are loaded by contact with each other. In this specification, "a state in which the second connector 30 is held by the first connector 10 at the set position P2" may be expressed as a "set state" or the like.

Although illustration and detailed description are omitted, the mating side connector 50 is also heated by the reflow furnace in a state of being arranged on the mating side substrate 7 coated with cream solder. As a result, each mating terminal 61 is soldered to the mating board 7.

[Connection between connector device and mating connector]
As shown in FIG. 1, the connector device 2 mounted on the board 6 is connected to the mating connector 50 mounted on the mating board 7. Specifically, the operator relatively fits the mating side connector 50 (the mating side housing 51) into the upper fitting recess 32 of the second housing 31. When substantially the entire mating connector 50 is fitted into the upper fitting recess 32, the lower surface of the mating housing 51 comes into contact with the upper surface of the intermediate main body 34 of the second housing 31, and the relative push-up of the second connector 30 is restricted. To do. In this state, the second terminal 41 (second center upper contact portion 42B, second outer upper contact portion 43B) and the mating terminal 61 come into contact with each other with elastic force. Since the contact action between the second terminal 41 and the mating terminal 61 is the same as the contact action between the first terminal 21 and the second terminal 41 already described, the description thereof will be omitted.

As described above, the connection between the connector device 2 and the mating connector 50 is completed, and the board-to-board connector 1 is configured. As a result, the two boards 6 and 7 are electrically connected via the board-to-board connector 1.

In the connector device 2 according to the present embodiment described above, the second connector 30 moves between the preset position P1 and the set position P2, and is held by the first connector 10 at the preset position P1 and the set position P2. The configuration was set. In the preset state, the first terminal 21 and the second terminal 41 are not elastically deformed (under the load due to contact), and in the set state, the first terminal 21 and the second terminal 41 are elastically deformed (under the load due to contact). ) It was configured to contact. According to this connector device 2 (board mounting method), the pre-assembled (preset state) connector device 2 can be soldered to the board 6. This makes it possible to heat the terminals 21 and 41 that are not subjected to the contact load. In other words, it is possible to prevent the terminals 21 and 41 that have been subjected to the contact load from being heated, and to suppress the bending and warpage that occur in the terminals 21 and 41 that are heated while applying the load. Further, after the temporarily assembled connector device 2 is soldered, the second connector 30 can be moved to bring the second terminal 41 into contact with the first terminal 21 with a normal contact pressure. As a result, as compared with the case where the step of soldering the first connector 10 to the substrate 6 and the step of connecting the second connector 30 to the first connector 10 are performed separately, it takes time and effort to mount the connector device 2 on the substrate. And time can be saved. That is, it is possible to suppress the deformation of the terminals 21 and 41 while saving labor for mounting the connector device 2 on the board.

Further, according to the connector device 2 according to the present embodiment, the second connector 30 is pulled out from the first connector 10 by engaging each subblock claw 36B with the subblock convex portion 15 (see FIG. 8). Can be regulated. As a result, the connector device 2 can be maintained in the preset state (preliminarily assembled state).

Further, according to the connector device 2 according to the present embodiment, each main lock claw 37B abuts on the main lock convex portion 18 to maintain a state in which each sublock claw 36B is engaged with the subblock convex portion 15. Can be done. As a result, the withdrawal of the second connector 30 can be restricted, and the connector device 2 can be maintained in the preset state. Further, by engaging each main lock claw 37B with the main lock convex portion 18 (see FIG. 12), it is possible to restrict the second connector 30 that has moved to the set position P2 from being pulled out and returning to the preset position P1. .. As a result, the connector device 2 can be maintained in the set state.

Further, according to the connector device 2 according to the present embodiment, the second connector 30 is set to the preset position P1 by the contact between the main convex side contact surface 18A and the main claw side contact surface 37C (see FIG. 9). The placed state can be maintained. Further, with the second connector 30 moving from the preset position P1 to the set position P2, each main claw side contact surface 37C slides on the main convex side contact surface 18A to move the main lock arm 37A in the radial direction. It is configured to be elastically deformed to the outside. According to this configuration, each main lock claw 37B can be restored and engaged with the main lock convex portion 18 after getting over the main lock convex portion 18 (see FIG. 12).
