Note that the side lock member 22 is located outward from the side wall portion 17, and therefore, as shown in FIG. 3 (b), a gap (gap) is formed between the side lock member 22 and the side wall portion 17. Occurs. When the electric wire connector 1 is fitted to the board connector 101, a portion on the back side of the lock arm receiving groove 117b in the side wall portion 117 of the board connector 101 enters the gap together with the auxiliary fitting for mounting 181 to form a side lock member. The side engagement protrusions 22c of 22 are engaged with the engagement openings 182 of the auxiliary fittings 181 for mounting the board connector 101, and function as a second lock mechanism for locking the board connector 101 and the electric wire connector 1 that are fitted. To do.

  Next, an operation for fitting the wire connector 1 to the board connector 101 will be described.

  4 is a perspective view showing a state in which the wire-to-board connector is fitted in the embodiment of the present invention. FIG. 5 is a three-view diagram showing a state in which the wire-to-board connector is fitted in the embodiment of the present invention. These are sectional drawings which show the state which the wire-to-board connector in embodiment of this invention fitted. 5, (a) is a top view, (b) is a front view, (c) is a side view, and in FIG. 6, (a) is a cross-sectional view taken along the line CC in FIG. 5 (a). (B) is DD sectional view taken on the line of Fig.5 (a), (c) is the principal part enlarged view of the EE arrow cross section of Fig.5 (a).

  When the electric wire connector 1 is fitted to the board connector 101 mounted on the circuit board, the operator operates the electric wire connector 1 with fingers or the like, and the lower surface as the fitting surface of the main body portion 14 of the electric wire connector 1 is the board. More specifically, the connector 101 is positioned to face the bottom wall portion 112 so as to face the upper surface as the fitting surface. In addition, the orientation of the wire connector 1 is adjusted so that the tip of the wire connector 1 on which the front locking member 16 is formed faces the same direction as the tip of the board connector 101 on which the front locked member 116 is formed. Then, the electric wire connector 1 is moved vertically relative to the circuit board from above the circuit board, and the main body portion 14 of the electric wire connector 1 is inserted into the fitting space 113 of the board side housing 111 of the board connector 101 from above. Then, as shown in FIGS. 4 to 6, the wire connector 1 is fitted to the board connector 101.

  At this time, the terminal support portion 114 of the board connector 101 enters the terminal accommodating opening 13 a of the electric wire connector 1. And the front-end | tip part of each electric wire side terminal 61 arrange | positioned in this terminal accommodation opening 13a enters into each terminal accommodation groove | channel 114a formed in the terminal support part 114, and contact part 164 of the board | substrate side terminal 161 and Contact. Thereby, the conductive wire of the electric wire 91 is electrically connected to the counterpart terminal member formed on the circuit board via the electric wire side terminal 61 and the board side terminal 161. 6A, the front engaging protrusion 16a of the front locking member 16 of the electric wire connector 1 engages with the front locked member 116 of the board connector 101, and FIG. As shown, the side engagement protrusion 22 c of the side lock member 22 of the electric wire connector 1 engages with the engagement opening 182 of the mounting auxiliary metal fitting 181 of the board connector 101. This prevents the electric wire connector 1 from being detached from the board connector 101. When locking, the operator does not need to operate any of the front lock member 16, the front locked member 116, the side lock member 22, and the auxiliary mounting bracket 181. The fitting operation can be easily performed.

  It should be noted that the click feeling caused by the engagement of the front lock member 16 and the front locked member 116 and the click feeling caused by the engagement of the side lock member 22 and the auxiliary mounting bracket 181 may be sufficiently felt. Therefore, the operator can accurately recognize that the fitting between the electric wire connector 1 and the board connector 101 is completed.

  Further, the first engaging convex portion 21a and the second engaging convex portion 21b of the electric wire connector 1 enter and engage with the first engaging groove 121a and the second engaging groove 121b of the board connector 101, respectively. . Thereby, the electric wire connector 1 is fitted to the board connector 101 in a state in which the electric wire connector 1 is accurately positioned with respect to the board connector 101. In other words, the operator only needs to engage the first engagement protrusion 21a and the second engagement protrusion 21b with the first engagement groove 121a and the second engagement groove 121b to position the electric wire connector 1 with respect to the board connector 101. Therefore, the fitting operation can be easily performed.

  As described above, the position of the contact portion 164 of the board-side terminal 161 in the front-rear direction of the board-side housing 111 is between the front locked member 116 and the engagement opening 182. Therefore, as shown in FIG. 6C, the contact portion between the electric wire side terminal 61 and the board side terminal 161 is located on the front engagement protrusion 16a and the front locked member 116 as the lock position of the first lock mechanism. It is located in the middle between the engagement location and the engagement location of the side engagement projection 22c and the engagement opening 182 as the lock position of the second lock mechanism.

  When the electric wire 91 whose end is connected to the electric wire connector 1 is rolled up and down, the electric wire side housing 11 has an engagement portion of the front engaging protrusion 16a and the front locked member 116, or a side engaging protrusion. A force is applied to rotate in the vertical direction with one of the engagement portions of the portion 22c and the engagement opening 182 as a fulcrum. And when the ratchet resulting from an unavoidable tolerance exists in the said engaging part, the electric wire connector 1 is displaced to some extent by rotation in the other engaging part. Even in such a case, since the contact point between the electric wire side terminal 61 and the board side terminal 161 is located in the middle of the engagement point, the displacement amount of the electric wire side terminal 61 relative to the board side terminal 161 is the other side. It becomes smaller than the displacement amount of the electric wire connector 1 in the engaging part. Therefore, the electric wire side terminal 61 is not detached from the substrate side terminal 161, and the contact state between the electric wire side terminal 61 and the substrate side terminal 161 is reliably maintained.

  Further, with respect to the front-rear direction of the board-side housing 111, the contact portion 164 is preferably located at the midpoint between the front locked member 116 and the engagement opening 182. The distance from the engagement point of the lock member 116 to the contact point between the electric wire side terminal 61 and the board side terminal 161, and the electric wire side terminal 61 and the board side from the engagement point of the side engagement protrusion 22 c and the engagement opening 182. It is desirable that the distance to the contact point with the terminal 161 is equal. In this case, even when a force is applied to the electric wire side housing 11 so as to rotate in the vertical direction with any engagement point as a fulcrum, the amount of displacement of the electric wire side terminal 61 relative to the board side terminal 161 is uniformly reduced. be able to. Therefore, the contact state between the electric wire side terminal 61 and the board side terminal 161 can be more reliably maintained.

  Further, as described above, the front locked member 116 is positioned right above the solder tail portion 162, and the engagement opening 182 is positioned right above the fixing lower end portion 183. Therefore, as shown in FIG. 6C, the engagement position of the front engagement protrusion 16 a and the front locked member 116 as the lock position of the first lock mechanism is located immediately above the solder tail portion 162. The engagement portion of the side engagement protrusion 22c and the engagement opening 182 as the lock position of the second lock mechanism is located directly above the lower end 183 for fixation.

  As a result, even when a strong force that pulls upward acts on the electric wire connector 1, the front engagement protrusion 16a and the front locked member 116 are engaged, and the side engagement protrusion 22c and the engagement opening 182 are engaged. Is not released, and the connection between the solder tail portion 162 and the circuit board and the connection between the fixing lower end 183 and the circuit board are not released. Accordingly, the fitting between the electric wire connector 1 and the board connector 101 can be reliably held, the contact state between the electric wire side terminal 61 and the board side terminal 161 can be more reliably maintained, and the board connector 101 can be maintained. The state of being fixed to the circuit board can also be securely held.
