FIGS. 22A and 22B are views showing a state in which the receptacle connector 10 is tilted when the receptacle connector 10 and the base connector 30 are combined. Figs. 23A and 23B are views showing a combination of the steps of the socket connector 10 and the susceptor connector 30, which is a cross-sectional view taken along line 22A-22B-22C-22D of Fig. 22A. Figs. 24A and 24B are diagrams showing a combination of steps from the states shown in Figs. 23A and 23B. 25A to 25C are views showing a combination of the steps of the socket connector 10 and the susceptor connector 30, which is a cross-sectional view taken along line 22E-22E shown in Fig. 22B.

The fitting guide rib 61 and the fitting rib groove 51b face each other, the side rib 62 and the side rib groove 52a face each other, and the end surface 711a of the bottom wall portion 711 in the fourth direction D4 and the inner side rib 422 is opposed to each other, and the contact opening slit 13 is opposed to the socket-side contact portion 35a of the susceptor contact piece 35, and the receptacle connector 10 and the pedestal connector 30 are in the first direction D1 or the second direction. D2 is relatively close. As a result, the fitting guide rib 61 is inserted into the fitting rib groove 51b, the side rib 62 is inserted into the side rib groove 52a, and the bottom wall portion 711 is housed in the lower side of the inner side rib 422 (the first direction D1 side) The socket side contact portion 35a of the susceptor contact piece 35 is inserted into the contact to expose the slit 13.

In particular, the socket connector 10 and the base connector 30 are preferably combined in accordance with the steps shown in Figs. 23A to 25C.

First, as shown in FIG. 22A, FIG. 22B, and FIG. 23A, the socket housing 11 of the receptacle connector 10 is inclined in the fourth direction D1 side in the first direction D1 side, as shown in FIG. 23B and FIG. 25A. The fitting guide rib 61 is inserted into the fitting rib groove 51b, and the end surface 711a of the bottom wall portion 711 in the fourth direction D4 is inserted into the lower side (the first direction D1 side) of the inner side rib 422. In other words, before the side ribs 62 are inserted into the side rib grooves 52a, the fitting ribs 61 are first inserted into the fitting rib grooves 51b.

The socket connector 10 is moved to the susceptor connector 30 in the first direction D1 while being substantially tilted. At a certain point in time, the side rib inclined portion 62a of the side rib 62 comes into contact with the wall in the third direction D3 of the side rib groove 52a. At this point of time, the fitting guide rib 61 is located in the vicinity of the fitting guide rib locking portion 51c of the fitting rib groove 51b as shown in Fig. 24A. Further, the bottom wall portion 711 is located in the vicinity of the inner side rib 422 as shown in Fig. 25B.

Further, when the receptacle connector 10 is further moved in the first direction D1, the side ribs 62 receive the reaction force in the fourth direction D4 from the side rib groove 52a. Therefore, the side rib 62 is bent in the fourth direction D4, and the fitting guide rib 61 is introduced into the fitting guide rib locking portion 51c and housed as shown in Fig. 24B. Similarly, as shown in FIG. 25C, the bottom wall portion 711 is introduced into the lower side (the first direction D1 side) of the inner side rib 422 and is accommodated. Here, in other words, in this state, the inner side rib 422 is housed in the socket side recess 70.

In this manner, the fitting guide rib 61 is housed in the fitting guide rib locking portion 51c, and the bottom wall portion 711 is accommodated in the lower side (the first direction D1 side) of the inner side rib 422, even in the case of The fourth direction D4 side of the socket housing 11 It is intended to move in a direction away from the base housing 31 (ie, the third direction D3), and also because the fitting guide rib 61 is locked to the fitting guide rib locking portion 51c, and the bottom wall portion 711 is housed on the inner side. Since the lower side of the rib 422 (the first direction D1 side) is difficult to separate from the base case 31 in the third direction D3 side of the socket housing 11.

After accommodating the fitting guide rib 61 of the fitting guide rib locking portion 51c and accommodating the inner side rib 422 of the socket side recess 70, a predetermined force or more is applied, and the socket is provided in the third direction D3 side. The connector 10 and the susceptor connector 30 are relatively close to each other in the first direction D1 or the second direction D2. Then, the extension rib 63 slides on the inclined surface of the latch portion 52b, and the side rib 62 is bent inside the fifth direction D5 and passes over the latch portion 52b, as shown in Figs. 24A and 24B, at the latch portion 52b. The first direction D1 side moves. That is, the extension rib 63 is engaged with the latch portion 52b, and is completely inserted into the side rib groove 52a.

When the side rib 62 and the extension rib 63 are completely inserted into the side rib groove 52a, the socket connector 10 and the pedestal connector 30 are in the state shown in Fig. 24B, and the formation of the socket connector-base connector pair is completed. . Further, when the extension rib 63 is engaged with the latch portion 52b, a click feeling is generated. Therefore, the operator can easily judge the end of the formation of the socket connector-base connector. In this manner, the engagement of the receptacle connector 10 with the base connector 30 is maintained by the engagement of the extension rib 63 with the latch portion 52b.

Here, the pair of side ribs 62, 62 are on the side of the fourth direction D4 of the socket housing 11, and protrude outward in the third direction D3. A through hole 621 penetrating in the third direction D3 is formed in the side rib 62. Therefore, the pair of side ribs 62, 62 are easily deformed inside the fifth direction D5. Thereby, when the receptacle connector 10 is combined with the base connector 30, because of the pair of side ribs 62 Since the 62 is deformed inside the fifth direction D5, the side rib 62 and the extension rib 63 are easily inserted into the side rib groove 52a, and are easily pulled out from the side rib groove 52a. Moreover, damage to the socket connector 10 or the susceptor connector 30 caused by the plug connector 10 of the cradle connector 30 can be reduced.

Next, a case where the susceptor connector 30 having the number of poles (number of electrodes) different from each other is combined with the receptacle connector 10 will be described with reference to the drawings. Here, the socket connector 10 and the 4-pole for the two poles will be described. The case where the base connector 30 is combined.

The position where the bottom wall portion 711 overlaps. Therefore, in the combined state, since the inner side rib 422 is housed in the lower side (the first direction D1 side) of the rear wall reinforcing convex portion 423, it is difficult to be detached from the base housing 31 in the third direction D3 side of the socket housing 11. Separation. Thereby, the fitting state of the base connector 30 and the receptacle connector 10 can be further enhanced.

Further, in the present embodiment, the socket-side recessed portion 70 has a notch portion 721 formed by cutting a part of the partition plate 72 in the fourth direction D4 side. Thereby, the socket side recessed portion 70 can be constructed by simply cutting out a part of the partition plate 72. Therefore, the susceptor connection with the number of electrodes can be suppressed with a simple configuration The device 30 is fitted to the receptacle connector 10.

Further, in the present embodiment, the surface of the base casing 31 in the second direction D2 side of the inner side rib 422 corresponds to the partition wall 72 having the rear wall reinforcing convex portion 423 protruding toward the second direction D2 side, in combination. In the state, the rear wall reinforcing convex portion 423 is disposed in the notch portion 721 of the partition plate 72. Thereby, the rear wall portion 32c can be reinforced by the rear wall reinforcing convex portion 423. Further, since the rear wall reinforcing convex portion 423 is disposed in the notch portion 721 of the partition plate 72, the wiring for obstructing the electric wire W is suppressed.
