  On the other hand, when the tip of the part of the first connection object 10 and the pair of first mark portions 170 of the body 100 are aligned in a straight line, the first connection object 10 is connected to the connector. And can be confirmed to be inserted straight (that is, at right angles to the length direction of the connector).

  After this confirmation, the insertion member 500 is further pushed toward the body 100. Then, the locking claws 521 of the pair of locking members 520 of the insertion member 500 are locked to the pair of locking recesses 151 of the body 100. At the same time, the pressing portion 530 of the insertion member 500 enters between the guide portion 230a and the first connection object 10 against the elastic force of the guide portion 230a of the first contact 200a. Then, the guide part 230a is elastically deformed upward.

  At this time, the pressing portion 530 is guided by the tapered surface 231a of the guide portion 230a, and further pushes down the first connection object 10 downward. Thereby, the 1st contact part of the 1st connection subject 10 press-contacts to the 1st contact parts 240a and 230b of the 1st and 2nd contacts 200a and 200b, respectively. In this way, the first connection object 10 is mechanically and electrically connected to the connector, and is in a completely connected state.

  In this completely connected state, the second mark portions 523 of the pair of locking members 520 are exposed through the pair of window portions 160 of the body 100. It is visually confirmed whether or not the second mark portion 523 and the pair of first mark portions 170 of the body 100 are aligned. As a result of this visual recognition, when the second mark portion 523 and the pair of first mark portions 170 of the body 100 are aligned in a straight line, the first connection object 10 is connected to the connector in a completely connected state. Can be confirmed. On the other hand, when the second mark portion 523 and the pair of first mark portions 170 of the body 100 are not aligned in a straight line, the connection of the first connection object 10 is performed again by the above-described procedure.

  On the other hand, the second connection object 20 is inserted into the second opening 120 of the body 100 with the actuator 400 positioned at the standing position. Then, the first connection object 20 enters between the hook 250a and the second contact portion 260a of the first contact 200a and between the support portion 240b and the second contact portion 250b of the second contact 200b. .

  Thereafter, the actuator 400 is rotated from the standing position to the recumbent position. Then, the bottom surface of the actuator 400 presses the second connection object 20 downward. Accordingly, the second connection object 20 is mechanically connected to the connector by being held between the actuator 400 and the second contact portions 260a and 250b of the first and second contacts 200a and 200b. The At this time, the second contact portion of the second connection object 20 is in pressure contact with the second contact portions 260a and 250b of the first and second contacts 200a and 200b. Thereby, the 2nd connection target object 20 is electrically connected to a connector.

  In such a connector, the pair of second mark portions 523 of the insertion member 500 exposed from the pair of window portions 160 of the body 100 and the pair of first mark portions 170 of the body 100 are aligned in a straight line. It is possible to confirm whether or not the first connection object 10 is in a completely connected state simply by visually checking whether or not there is. Therefore, the confirmation work is simplified as compared with the conventional example.

  Further, in the state before connection, the tip of the part of the first connection object 10 exposed through the pair of hole portions 522 and the window portion 160 and the pair of first mark portions 170 of the body 100 are aligned in a straight line. It is possible to confirm whether or not the first connection object 10 is inserted obliquely with respect to the connector simply by visually checking whether or not the For this reason, it can prevent beforehand that the said 1st connection target object 10 will be in an incomplete connection state by inserting the 1st connection target object 10 diagonally with respect to a connector.

  The indicator structure S of the connector includes a window portion provided in the body so as to communicate with the first opening portion, a first mark portion provided in the vicinity of the window portion of the body, and a first connection. A second mark portion provided on the object, and the second mark portion is exposed from the window portion when the first connection object is in a completely connected state, and the first mark portion and The design can be arbitrarily changed as long as it is arranged in a straight line.

  About the 1st and 2nd mark part, although it was mentioned as a crevice, it is not limited to this. For example, it may be a convex portion or may be written by paint. Moreover, it does not need to be a long thing and can also be made into a circular point etc. Note that it is sufficient that there is at least one first and second mark portion.

  Moreover, although the said 1st mark part was supposed to be located on the vertical line of the back side surface of the 1st opening part of a body, it is not limited to this.

  Moreover, although the said 2nd mark part was provided in the insertion member, you may make it provide directly in a 1st connection target as mentioned above. In this case, whether or not the insertion member is provided is arbitrary. When the insertion member is provided, the second mark portion may be exposed from a front through hole or a notch provided on the insertion member and communicating with the window portion of the body in a completely connected state.

  About the said insertion member, the function which press-contacts the 1st contact part of the 1st, 2nd contact to the 1st contact part of the mechanical attachment of the 1st connection object, and the said 1st connection object. However, the present invention is not limited to this. That is, the insertion member is inserted into the first opening of the body, and the second mark portion of the insertion member is exposed from the window portion of the body when the first connection object is in a completely connected state. The design can be arbitrarily changed as long as it is aligned with the first mark portion.

  The window portion of the body may be at least one, and the shape of the window portion can be arbitrarily changed. Further, although the window portion is a hole that penetrates from the upper surface of the body to the ceiling surface of the first opening portion, it may be at least a hole that communicates with the first opening portion. For example, the window portion may be a hole penetrating from the side surface or bottom surface of the body to the inner surface or inner bottom surface of the first opening. In this case, the first mark portion may be provided in the vicinity of the window portion such as the side surface or the bottom surface of the body, and the second mark portion may be provided at a position corresponding to this.

  Although the said connector demonstrated that two connection objects were connected, it is not limited to this. For example, in place of the second connection object, the connector may be a plug in which a signal line of a cable is solder-connected to the first and second contacts. Alternatively, the first and second contacts may be receptacles connected to the device substrate.

  Further, the connector has the first and second contacts, but it is sufficient that the connector has at least one contact. About this contact, what is necessary is just to have the 1st contact part which can contact at least the contact part of a 1st connection target object, and can change a design arbitrarily.

  The actuator is pivotally supported by the hooks and support portions of the first and second contacts, but may be pivotally supported by both edge portions of the second opening of the body. . In this case, the hook and the support portion are unnecessary.
