Hereinafter, a method of mounting the first connector Ca and the second connector Cb shown in FIGS. 1A to 3B will be described in detail.

The first connector Ca and the second connector Cb are relatively close to each other in the ZZ'direction. The plurality of guide protrusions 130b of the second connector Cb are each inserted into the plurality of guide grooves 130a of the tubular portion 101a of the first connector Ca. At the same time, the tubular portion 101b of the second body 100b of the second connector Cb is inserted into the tubular portion 101a of the first body 100a of the first connector Ca. Then, the guide protrusions 130b are guided by the guide grooves 130a, and the tips of the two engaging arms 110a of the first body 100a come into contact with the two second engaging portions 120b, respectively, and the two engaging arms 110a Are elastically deformed so as to be separated from the outer peripheral surface 110b. When the two second engaging portions 120b are engaged in the first engaging portion 120a of the two engaging arms 110a, the two engaging arms 110a are restored respectively. As a result, the first surface 111a of the two engaging arms 110a faces the second surface 111b of the outer peripheral surface 110b of the second body 100b with contact or a slight gap, respectively, and the first surface of the engaging arm 110a The guide surface 112a faces the two second guide surfaces 112b of the outer peripheral surface 110b of the second body 100b, respectively, and the insertion space α is partitioned between the first guide surface 112a and the second guide surface 112b. The two guide recesses 140b of the second connector Cb are located on the Y-direction side of the insertion space α, respectively. As described above, the first connector Ca and the second connector Cb are mounted. In this mounted state, the terminal 200a of the first connector Ca and the terminal 200b of the second connector Cb are in contact with each other, and the first connector Ca and the second connector Cb are connected.

A method of disconnecting the first connector Ca and the second connector Cb connected as described above will be described in detail. Prepare a substantially U-shaped release jig J. After that, the two arms J1 of the release jig J are each inserted into the insertion space α from the guide recess 140b of the second connector Cb. Then, the arm J1 is guided by the first guide surface 112a of the engaging arm 110a of the first connector Ca and the second guide surface 112b of the outer peripheral surface 110b of the second body 100b of the second connector Cb, respectively, and the engaging arm 110a It is inserted between the first surface 111a and the second surface 111b of the outer peripheral surface 110b, respectively. As a result, the arm J1 presses the engaging arm 110a, and elastically deforms the engaging arm 110a so as to be separated from the outer peripheral surface 110b. Due to the elastic deformation of the engaging arm 110a, the first engaging portion 120a of the engaging arm 110a is displaced so as to be separated from the second engaging portion 120b of the outer peripheral surface 110b, and the first engaging portion 120a and the second engaging portion 120a are separated from each other. The engagement with the engaging portion 120b is released. In this way, the first connector Ca and the second connector Cb are in a detachable state. By relatively separating the first connector Ca and the second connector Cb in the ZZ'direction from this detachable state, the first connector Ca is detached from the second connector Cb. At this time, the terminal 200a of the first connector Ca and the terminal 200b of the second connector Cb are not in contact with each other, and the connection between the first connector Ca and the second connector Cb is released.

As described above, when the arm J1 of the releasing jig J is inserted between the first surface 111a of the engaging arm 110a and the second surface 111b of the outer peripheral surface 110b, the arm J1 is inserted into the stopper 160b (second guide protrusion). Each of them abuts on the portion 130b), and further movement in the Y'direction is prevented. At the same time, the arm J1 is held by the holding portion 150b of the second connector Cb. For example, the arm J1 is brought into contact with the first surface 141b of the guide recess 140b of the second connector Cb from the Z direction side, and is also brought into contact with the contact portion 151b of the second connector Cb from the Z'direction side. When the first connector Ca and the second connector Cb are separated, the arm J1 moves in the Z'direction together with the second connector Cb while being held by the holding portion 150b. In a state where the arm J1 of the release jig J is inserted between the engagement arm 110a and the second surface 111b of the outer peripheral surface 110b of the second body 100b, the intermediate portion of the release jig J is the first. 2 Along the flange 102b of the body 100b. Since the plate thickness of the intermediate portion of the release jig J is oriented in the YY'direction, the intermediate portion of the release jig J is less likely to get in the way.

The connection structure C1 as described above exhibits the following technical features and effects. First, the first engaging portion 120a of at least one engaging arm 110a of the first connector Ca and at least one second engaging portion 120b of the outer peripheral surface 110b of the second body 100b of the second connector Cb. The engagement (lock) can be easily released. The reason is as follows. 1) At least one second guide surface 112b of the first guide surface 112a of the at least one engaging arm 110a and the outer peripheral surface 110b of the second body 100b extends so as to be separated from each other from the Y direction to the Y'direction. When the arm J1 of the releasing jig J is inserted between the first guide surface 112a and the second guide surface 112b, the first guide surface 112a and the second guide surface 112b engage the arm J1 with the first surface of the arm 110a. Guided between the 111a and the second surface 111b of the outer peripheral surface 110b of the second body 100b. Therefore, the arm J1 of the releasing jig J can be easily inserted between the first surface 111a of the engaging arm 110a and the second surface 111b of the outer peripheral surface 110b of the second body 100b. 2) When the guide recess 140b is provided in at least one guide protrusion 130b of the second body 100b, the arm J1 of the releasing jig J is guided by the guide recess 140b to guide the first guide surface 112a and the first guide recess 140b. It can be easily inserted between the two guide surfaces 112b. 3) When the second connector Cb includes the holding portion 150b, the arm J1 of the releasing jig J is inserted between at least one engaging arm 110a and the outer peripheral surface 110b of the second body 100b, and the engagement is concerned. With the first engaging portion 120a of the combined arm 110a and the outer peripheral surface 110b of the second body 100b disengaged from at least one second engaging portion 120b, the arm J1 has the first engaging portion 120a and the first engaging portion 120a. 2 It is held by the holding portion 150b on the Z'direction side of the engaging portion 120b. Therefore, the arm J1 of the release jig J can be separated from the second connector Cb and the first connector Ca in the Z'direction while being held by the holding portion 150b. 4) There are two engaging arms 110a, two second surfaces 111b of the outer peripheral surface 110b of the second body 100b of the second connector Cb, and two second guide surfaces 112b of the outer peripheral surface 110b. In some cases, the two arms J1 of the substantially U-shaped or substantially V-shaped releasing jig J are combined with the first guide surface 112a of the two engaging arms 110a and the two second guide surfaces 112b of the outer peripheral surface 110b. Are simultaneously inserted between the first surface 111a of the two engaging arms 110a and the second surface 111b of the outer peripheral surface 110b, respectively, and the first engaging portion 120a and the outer peripheral surface of the two engaging arms 110a are inserted. The engagement of 110b with the two second engaging portions 120b can be disengaged substantially at the same time.

Secondly, since at least one second guide surface 112b of the second connector Cb uses a part (arc surface) of the outer peripheral surface 110b of the second body 100b as it is, the second guide surface 112b is separately used. The manufacturing cost of the second connector Cb can be reduced as compared with the case where the two bodies 100b are formed on the outer peripheral surface 110b.

Thirdly, when the stopper 160b is provided on either one of the at least one engaging arm 110a of the first connector Ca and the outer peripheral surface 110b of the second body 100b of the second connector Cb, the stopper 160b is used for releasing the jig. By abutting the tool J from the Y'direction side, the arm J1 of the releasing jig J is inserted between at least one engaging arm 110a and the outer peripheral surface 110b of the second body 100b by a predetermined value or more. Can be prevented.
