  In the case of the conventional electrical connector with a locking mechanism, the slider 7 is required separately from the first connector 3 and the second connector 5, and the number of parts is at least three. For this reason, there is a demand for reducing the number of parts and drawing out the possibility of cost reduction. Further, since the slider 7 is operated along the mounting surface 2a of the circuit board 2, there is a problem that it is difficult to operate when there are mounted components around the slider.

  The present invention has been made paying attention to such points, and the object of the present invention is to connect the second connector with respect to the first connector mounted on the mounting destination member on the side opposite to the first connector. When the first connector is inserted from the first connector, the first fitting of the two connectors is performed, and when the second connector is moved along the surface of the mounting member, the second fitting of the two connectors is performed. The slider and other members are not required, the number of parts is reduced to reduce the cost, and the slider is not required to be operated to improve operability. Provided is a pair of electrical connectors with a lock mechanism that can selectively lock with a weak force and selectively lock both connectors with a relatively strong force by the second fitting. In the door.

In order to achieve the above object, a first pair of electrical connectors with a locking mechanism according to the present invention includes:
When the side closer to the mounting destination member when mounted in the thickness direction is the mounting side, and the opposite side is the anti-mounting side,
A first connector; and a second connector to be fitted to the first connector from the opposite side of the first connector;
The first connector includes a first housing and a first contact provided on the first housing,
The first housing has a bottom wall and two side walls provided on the side opposite to the mounting surface of the bottom wall and facing the width direction orthogonal to the thickness direction, and the first housing is between the two side walls. A housing part opened toward the non-mounting side is formed,
The first contact has a contact portion arranged facing the housing portion, and a connection portion led out to the outside of the first housing,
The second connector includes a second housing formed in a shape corresponding to the housing portion of the first housing and inserted into the housing portion, and a second contact provided on the second housing. Prepared,
The second housing has side walls on both sides in the width direction,
The second contact is inserted in the depth direction perpendicular to both the thickness direction and the width direction when the second housing is inserted into the housing portion of the first housing. A contact portion disposed so as to contact the contact portion of the first contact when displaced by a predetermined distance toward the near side, and a connection portion that connects a terminal end on the far side in the depth direction of the conductive member extending in the depth direction. Have
A convex portion that protrudes outward in the width direction is provided on the outer surface in the width direction of the side wall of the second housing, and the width on the inner surface in the width direction of the side wall of the first housing. A recess extending outward in the depth direction and extending in the depth direction, and the end on the mounting side communicates with the recess on the back side in the depth direction from the recess, and the end on the anti-mounting side is the anti-mounting side of the side wall. And a communication groove leading to
When the second connector is pressed against the first connector from the counter-mounting side of the first connector along the thickness direction, the convex portion is fitted to the end of the communication groove on the counter-mounting side. When the end of the communication groove reaches the mounting side, the second housing is inserted into the housing portion of the first housing, and the first fitting of the two connectors is performed. When the connector is shifted forward by a predetermined distance along the depth direction, the convex portion moves forward along the concave portion in the depth direction, and the wall constituting the concave portion moves in the thickness direction. The second connector of the two connectors is configured to be blocked.

  When the second connector is pressed against the first connector from the counter-mounting side of the first connector along the thickness direction, the convex portion is fitted to the end of the communication groove on the counter-mounting side. In addition, when reaching the mounting side end portion along the communication groove, the second housing is inserted into the housing portion of the first housing.

It is possible to selectively perform locking with a relatively weak force and locking both the connectors with a relatively strong force by the second fitting.

  The second pair of electrical connectors with a locking mechanism according to the present invention can obtain the effects obtained by the first pair of electrical connectors with a locking mechanism, and further, from the second fitting to the first If the setting is made so that a click feeling can be obtained when the locking claw is engaged with the engaging portion, the second fitting can be performed. If it is set so that the locking claw can be removed from the engaging portion, the second fitting is returned to the first fitting, and the second connector is For example, the conductive member or other components can be easily recycled.

The locking claw is configured to be hooked on the engaging portion when it is touched. In the case of this embodiment, as shown in FIGS. 1 to 3, 5, 6, 14, and 20, the bottom wall 212 of the second housing 210 has the above-mentioned end at the front side in the depth direction. A locking claw 212b is provided, and the engaging portion 111a that receives the locking claw 212b is provided at the end of the bottom wall 111 of the first housing 110 on the near side in the depth direction. The locking claw 212b protrudes from the bottom wall 212 to the mounting side, and the engaging portion 111a protrudes from the bottom wall 111 to the non-mounting side. The first connector 100 and the second connector When the second fitting of 200 is performed, the locking claw 212b is elastically deformed and gets over the engaging portion 111a, and then is restored to be engaged with the engaging portion 111a. Yes. In this case, the angle between the engaging claws 212b and the engaging portions 111a is formed more gently than in the depth direction, and the second connector 200 is applied with a certain force. When the locking claw 212b is shifted to the back along the depth direction, the engagement of the locking claw 212b with the engaging portion 111a is released, thereby enabling the second fitting to be released. The angles of the surfaces that are engaged with each other may be formed gently at least one of the locking claw and the engaging portion. Moreover, the electrical connector with a locking mechanism according to the present invention is configured such that the angles of the engaging claws and the engaging portions of the engaging portions are formed at a steeper angle than in the depth direction, thereby making it difficult to release the engaging. The function may be enhanced, and by doing so, it is possible to prevent the second fitting from being easily released. You may provide the said latching claw in the other site | part of the said 2nd housing, or the said engaging part in the other site | part of the said 1st housing. Contrary to this embodiment, when the first housing is provided with a locking claw, the second housing is provided with an engaging portion for receiving the locking claw, and the second fitting is performed. In addition, the engaging claw may be configured to be hooked on the engaging portion.

  As shown in FIGS. 1, 2, 4, 5 to 7, the side walls 112 of the first housing 110 and the side walls 211 of the second housing 210 protrude in the width direction. When the first fitting is performed, the protrusions 211c of the second housing 210 are made to be elastically deformed by the elastic deformation of the first housing 110 or the second housing 210 when the first fitting is performed. The fitting force between the first housing 110 and the second housing 210 is increased by moving over the protrusion 112e of the first housing 110 to the mounting side. In this embodiment, the protrusion 112e of the first housing 110 is provided between the first recess 112a and the second recess 112c, and the protrusion 211c of the second housing 210 is the first It is provided between the first convex portion 211a and the second convex portion 211b. However, you may provide the said protrusion part in the other site | part of the said 1st housing or the said 2nd housing.

  As described above, the conductive member 400 is an electric wire. Then, the movement operation of the second connector 200 along the depth direction is performed by pulling the conductive member 400.

  As shown in FIGS. 1 and 2, reinforcing tabs 130 to be mounted on the mounting destination member 300 are provided on both side walls 112 of the first housing 110. The reinforcing tab 130 is made of metal, and when the first connector 100 is soldered to the mounting member 300, the mounting side portion is soldered to the mounting member 300. The reinforcing tabs 130 are located on the side walls 112 of the first housing between the first communication groove 112b and the second communication groove 112d and corresponding to the protrusions 112e. Each is provided on the outside in the width direction. Each of the reinforcing tabs 130 is press-fitted into a groove penetrating in the thickness direction of each of the side walls 112, but may be provided by being integrally formed with each of the side walls.

  Therefore, in the case of the pair of electrical connectors with a locking mechanism according to the above embodiment, the second connector 200 is connected to the first connector 100 in the thickness direction from the opposite mounting side of the first connector 100 as shown in FIG. As it is pushed along, the first convex portion 211a and the second convex portion 211b fit into the end portions of the first communication groove 112b and the second communication groove 112d on the side opposite to the mounting side. In addition, the second housing 210 is inserted into the accommodating portion 114 of the first housing 110 when reaching the mounting side end portions of the first communication groove 112b and the second communication groove 112d. Then, the first fitting of the two connectors is performed by the frictional resistance of the portion where the two housings and the two contacts are in contact with each other, whereby the two connectors are locked with a relatively weak force. Next, when the second connector 200 is shifted forward by the predetermined distance along the depth direction (shifted in the direction indicated by the arrow in FIGS. 9 to 11), the first convex portion 211a and the second convex portion The portion 211b moves forward in the depth direction along the first concave portion 112a and the second concave portion 112c, and the wall that forms the first concave portion 112a and the second concave portion 112c has the thickness. Movement in the vertical direction is prevented. Then, the second fitting of the two connectors is performed by the frictional resistance of the portions where the two housings and the two contacts are in contact, and the first convex portion 211a and the second convex portion 211b are connected to the wall. Therefore, the two connectors can be locked with a relatively strong force.

  In that case, since a member such as the slider is unnecessary, the number of parts is reduced, and the possibility of cost reduction is drawn. The first fitting can be performed by pressing the second connector 200 against the first connector 100 from the side opposite to the mounting side of the first connector 100 along the thickness direction. The fitting can be performed by shifting the second connector 200 forward by a predetermined distance along the depth direction, and the operation of the slider or the like is not necessary, so that the operability is improved. In particular, for example, when a part or the like is mounted on the surface of the mounting member and there is not enough space for a hand, the slider may not be operated. If it is a connector, operation may be possible. Furthermore, it is possible to selectively lock both the connectors with a relatively weak force by the first fitting, and lock both the connectors with a relatively strong force by the second fitting. As described above, the pair of electrical connectors with a locking mechanism according to the above embodiment is configured so that the second connector 200 is connected to the first connector 100 on the side opposite to the first connector 100 mounted on the mounting member 300. When the second connector 200 is moved along the surface of the mounting member 300, the second fitting of the two connectors is performed. Therefore, it is possible to reduce the number of parts by eliminating the need for a member such as the slider and to reduce the cost, and to improve the operability by eliminating the need for the operation of the slider. The two connectors are locked with a relatively weak force by the fitting, and the two connectors are locked with a relatively strong force by the second fitting. It is possible to selectively perform.

In this way, it is possible to reliably prevent the return from the second fitting to the first fitting. Further, if it is set so that a click feeling is obtained when the locking claw 212b is engaged with the engaging portion 111a, it is possible to easily confirm that the second fitting has been performed. Furthermore, if it sets so that the said latching claw 212b can be removed from the said engaging part 111a, it will return from a 2nd fitting to a 1st fitting, and also will remove the 2nd connector 200 from the 1st connector 100. For example, the conductive member 400 or other parts can be easily recycled.
