The rib escape portion 16 is provided at a position corresponding to the inter-contact rib 66 of the base connector 3 in the combined state, and functions to avoid contact with the inter-contact rib 66 . The rib escape portion 17 is provided at a position corresponding to the tamper-resistant rib 67 of the base connector 3 in the combined state, and functions to avoid contact with the tamper-resistant rib 67 .

Next, the socket contact 50 will be described in detail. As shown in FIGS. 17 and 18 , the socket contact 50 has: a socket contact base 52 , a pair of socket contact clamping pieces 53 , and a locking bar 54 . The socket contact base 52 secures the cable 5 . A pair of socket contact holding pieces 53 are opposite in the third direction D3, as shown in FIG. 3 , a pair of socket contact holding pieces 53 hold the base contact 80 of the base connector 3 in the combined state The socket-side connecting portion 82 of the socket is connected electrically and mechanically. The lock lever 54 protrudes in the second direction D2.

As shown in FIG. 18 , the front end portion 53 a of the receptacle contact holding piece 53 on the fourth direction D4 side is rounded so as to spread in the fourth direction D4 . The lower end portion 53b of the receptacle contact holding piece 53 on the first direction D1 side is crushed and rounded.

The receptacle connector 2 and the base connector 3 having the aforementioned structure are combined as follows to form the receptacle base connector pair 1 shown in FIG. 1 and FIG. 2 . The receptacle connector 2 is moved in the first direction D1 in a state where the base connector 3 is arranged on the lower part and the receptacle connector 2 is arranged on the upper part. Connect the socket contact 50 with the base contact 80, insert the inter-contact rib 66 into the rib avoidance portion 16, insert the tamper-resistant rib 67 into the rib avoidance portion 17, and make the locking portion 14 and the locking engagement portion 64 to engage with each other so that the detachment preventing rib 15 engages with the rib engaging portion 65 .

Thus, the receptacle base connector pair 1 is formed, and the assembled state is maintained. For example, the receptacle connector 2 is prevented from coming off in the second direction D2 by the engagement of the lock portion 14 and the lock engagement portion 64 . The receptacle connector 2 is prevented from being detached in the fifth direction D5 by the engagement between the detachment preventing rib 15 and the rib engaging portion 65 .

According to the receptacle connector 2 of the first embodiment having the above structure, the following effects are obtained. In the receptacle connector 2 of the first embodiment, the receptacle contact arrangement part 20 has a visual confirmation function for visually confirming whether the receptacle contact 50 connected to the cable 5 is arranged at the normal position of the receptacle contact arrangement part 20 Use windows 25a, 25b. Therefore, whether or not the receptacle contact 50 is arranged at the normal position of the receptacle contact arrangement part 20 can be easily and visually detected by using the visual confirmation windows 25 a and 25 b.

Furthermore, in the receptacle connector 2 according to the first embodiment, when the receptacle contacts 50 connected to the cables 5 are arranged at the normal position of the receptacle contact arrangement part 20 , the fifth direction D5 side of the receptacle contacts 50 The end portion of each is disposed on the window 25 for visual confirmation. Therefore, whether or not the receptacle contact 50 is arranged at the normal position of the receptacle contact arranging portion 20 can be easily detected visually by using the easily recognized end portion of the receptacle contact 50 on the fifth direction D5 side.

Moreover, in the receptacle connector 2 of 1st Embodiment, the windows 25a and 25b for visual confirmation are arranged in multiple numbers in the 1st direction D1. The visual confirmation windows 25a and 25b adjacent to each other in the first direction D1 are arranged in a shifted manner in the third direction D3. Therefore, it is easy to simultaneously confirm visually the window 25a for visual confirmation of an upper stage, and the window 25b for visual confirmation of a lower stage simultaneously.

In addition, in the receptacle connector 2 of the first embodiment, the visual confirmation windows 25a and 25b adjacent in the third direction D3 are arranged in a shifted manner in the fourth direction D4. Therefore, the effect can be further enhanced.

Furthermore, in the receptacle connector 2 according to the first embodiment, the receptacle contact groups 51a, 51b are arranged in a plurality of rows in the first direction D1. The receptacle contact groups 51a and 51b adjacent to each other in the first direction D1 are arranged in a shifted manner in the third direction D3. The receptacle contacts 50a and 50b adjacent to each other in the third direction D3 are arranged in a shifted manner in the fourth direction D4. Therefore, the creepage distance of adjacent receptacle contacts 50 can be ensured much.
