The first connector includes a housing body (25) inserted into the insertion chamber, and a housing body (25) that is coupled to the housing body and cooperates with the locking portion to connect the first connector and the second connector. An arm portion (31) for locking the coupled state and an operation portion (33) for releasing the lock by the arm portion are provided, the arm portion being coupled to the outer surface of the housing body and extending in the insertion direction. Two connecting portions (35) arranged in orthogonal directions, two extending portions (37) extending from the connecting portions in the insertion direction outside the outer surface of the housing body, and a horizontal beam portion (39) connecting the extending ends thereof, the horizontal beam portion being provided with a locked portion (43) protruding toward the housing body and capable of being engaged/disengaged with the locking portion; The operation portion has a base end coupled to the lateral beam portion, has a surface facing the outer surface of the housing body, and has a plate shape extending in a direction opposite to the insertion direction, and the first connector. is inserted into the second connector, the side wall is positioned between the operation portion and the housing body, and faces the side wall of the operation portion facing the side wall or the side wall facing the operation portion. When a load directed toward the side wall is applied to the extending end of the operating portion, the extending end of the operating portion serves as a force point, the base end of the operating portion acts as a point of action, and itself serves as a fulcrum. It is characterized in that a projection (45) is provided so as to protrude.

According to this configuration, when an operator applies a load directed toward the side wall to the extended end of the operating portion, the extended end of the operating portion serves as a force point, the projecting portion serves as a fulcrum, and the engaged portion serves as a point of action. By this principle, the locking portion moves away from the side wall. As a result, the locking portion and the locked portion are not aligned in the insertion direction, and the engagement between the locking portion and the locked portion is released. Thereby, the first connector and the second connector (hereinafter referred to as both connectors) can be easily separated.

In addition, since it is possible to change how the load is applied to the arm portion when the two connectors are connected and disconnected, it is possible to prevent a portion where the load is concentrated on the arm portion both during connection and disconnection. Therefore, deterioration due to use of the connector device can be prevented.

In the above aspect, the projecting portion is provided on a surface of the operation portion facing the side wall, and a rib ( 46) is preferably provided.

It becomes easier to release the joint.

In the above aspect, it is preferable that the protruding end surface of the protruding portion has an arcuate shape protruding toward the side wall in a side view.

According to this configuration, when a load is applied to the extended end side of the operating portion, the projecting portion rolls along the wall surface of the side wall, and the operating portion moves in the direction opposite to the insertion direction. This facilitates disengagement between the locking portion and the locked portion.

In the aspect described above, the engaged portions may be provided at both ends of the lateral beam portion.

According to this configuration, the two engaged portions separated in the direction orthogonal to the insertion direction are engaged with the engaging portion, thereby preventing the coupled connectors from rattling and coupling the two connectors together. is held stable.

In the above aspect, it is preferable that the side wall is provided with a recess (15A) that is recessed toward the insertion chamber and receives the operation section.

According to this configuration, the size of the connector device in the coupled state can be reduced.

According to the present invention, in a connector device for connecting two connectors, it becomes easy to separate the two connectors.

The release operation portion 33 is coupled to the housing body 25 via the arm portion 31 , and the pressing portion 49 is movable back and forth with respect to the housing body 25 .

Next, operation of the connector device 1 according to the present invention will be described with reference to FIGS. 5 and 6. FIG.

When the plug-side connector 5 is inserted into the surface-mounted connector 3 , the locked portion 43 contacts the locking portion 29 . When the locked portion 43 comes into contact with the locking portion 29 , a forward load is applied from the locking portion 29 to the locked portion 43 . At this time, the load is applied mainly to the connecting portion 35 of the arm portion 31, and the connecting portion 35 serves as a fulcrum (hereinafter referred to as a fulcrum at the time of insertion), so that the extending portion 37 rotates around the connecting portion 35. Arm portion 31 is deformed. As a result, the locking portion 29 moves in a direction (forward) to avoid the locked portion 43 (see FIG. 5A). Further, when the operator inserts the plug-side connector 5 into the surface-mounted connector 3 and moves the locked portion 43 below the locking portion 29, a forward load applied to the lower end of the arm portion 31 is applied. It is released, and the bending deformation of the arm portion 31 is released. As a result, the engaged portion 43 moves rearward, and the engaging portion 29 and the engaged portion 43 are vertically aligned (see FIG. 5B). As a result, the locking portion 29 and the locked portion 43 are engaged with each other, restricting the upward movement of the plug-side connector 5 and maintaining the state in which the plug-side connector 5 and the surface mount connector 3 are coupled. (locked).

When separating the plug-side connector 5 from the surface-mounted connector 3, the operator presses the pressing portion 49 rearward. As a result, the pressing portion 49 is the force, and the projecting portion 45, more specifically, the point of contact P (see FIG. 6A) between the tip surface 45A of the projecting portion 45 and the front surface of the lateral side wall 15 of the header 9 is the fulcrum (see FIG. 6A). A load directed forward is applied to the lower end of the release operation portion 33 by the so-called principle of leverage with the lower end of the release operation portion 33 acting as a point of action. As a result, the arm portion 31 is flexurally deformed at the substantially central portion in the vertical direction and at the coupling portion 35, and the engaged portion 43 located at the lower end of the release operating portion 33 moves forward (see FIG. 6A). . When the operator presses the pressing portion 49 with a sufficient load, the locked portion 43 moves forward of the locking portion 29, and the engagement between the locked portion 43 and the locking portion 29 is released. The engaged portion 43 can be moved upward (see FIG. 6(B)). At this time, when the operator lifts the plug-side connector 5, the plug-side connector 5 and the surface-mounted connector 3 can be separated (see FIG. 6(C)).

In this manner, the pressing portion 49 releases the engagement between the locking portion 29 and the locked portion 43 from the operator, and the operation input ( It functions as a receiving unit that receives (pressing).

Next, effects of the connector device 1 according to the present invention will be described. In order to lock both connectors 3 and 5, it is sufficient to insert the connector on one side (plug side connector 5) into the connector on the other side (surface mount type connector 3). be.

In this embodiment, the arm portion 31 extends along the forward direction (downward) of the insertion direction of the plug-side connector 5 . As a result, when the plug-side connector 5 is inserted into the surface mount connector 3, the arm portion 31 is more likely to bend and deform than when the arm portion 31 extends in the left-right direction. This makes it easier for the locked portion 43 to move to the position where it engages with the locking portion 29 during insertion, so that the two connectors 3 and 5 can be locked more easily.

Further, when both connectors 3 and 5 are locked, the pressing portion 49 is pushed backward to deform the connecting portion 35 of the arm portion 31, thereby engaging the locking portion 29 and the locked portion 43. can be released. Thereby, the operator can easily separate the plug-side connector 5 and the surface-mounted connector 3 (that is, unlock).

When the operator presses the pressing portion 49, the lower end portion of the release operation portion 33 is pushed by the principle of leverage with the point of contact P between the tip end surface 45A of the projecting portion 45 and the front surface of the lateral side wall 15 of the header 9 as a fulcrum. is loaded forward. As a result, a forward load is applied to the lower end of the arm portion 31 connected to the lower end portion of the release operation portion 33, and the engagement between the locking portion 29 and the locked portion 43 is released. By using the principle of leverage in this way, a larger load can be applied to the lower end portion of the arm portion 31, so that the vicinity of the connecting portion 35 of the arm portion 31 and the entire arm portion 31 can be easily deformed. Therefore, the engagement between the locking portion 29 and the locked portion 43 can be easily released, and the plug-side connector 5 and the surface mount connector 3 can be easily separated.

The provision of the protruding portion 45 makes it possible to configure a fulcrum for releasing, so the configuration is simple. Further, since the release operation portion 33 is provided with the rib 46 extending from the protrusion 45 to the upper edge, it is possible to prevent bending deformation of the release operation portion 33 from the protrusion 45 to the upper edge at the time of unlocking. . As a result, the load applied to the pressing portion 49 at the time of unlocking can be more effectively transmitted to the lower end side of the unlocking operation portion 33, so that the arm portion 31 connected to the proximal end of the unlocking operation portion 33 can be displaced. The lower end portion is easily moved forward, and the engagement between the locking portion 29 and the locked portion 43 is easily released.

In this embodiment, the tip surface 45A of the projecting portion 45 is formed in an arc shape. Accordingly, when a rearward load is applied to the pressing portion 49, the protruding portion 45 rolls along the front surface of the front lateral side wall 15 on the tip surface 45A. At this time, the lower end of the arm portion 31 moves from the position indicated by the two-dot chain line in FIG. 6(A) to the position indicated by the solid line, that is, forward and upward as indicated by the arrow in FIG. 6(A). This makes it easier to release the engagement between the locking portion 29 and the locked portion 43 than when the lower end of the arm portion 31 simply moves forward. Therefore, unlocking becomes easier, and separation of the plug-side connector 5 and the surface-mounted connector 3 becomes easier.

When an operator inserts the plug-side connector 5 into the surface-mounted connector 3 and locks them together, the load concentrates on the connecting portion 35, and the arm portion 31 deforms mainly at the connecting portion 35 (see FIG. 5A). )reference). On the other hand, when the connectors 3 and 5 are separated from each other by unlocking, the projecting portion 45 serves as a fulcrum in addition to the connecting portion 35 of the arm portion 31, and the extending portion 37 is elastically deformed (FIG. 6(B)). reference). As a result, the load is distributed when both connectors 3 and 5 are separated. In this manner, the load applied to the arm portion 31 changes depending on whether the connectors 3 and 5 are locked or unlocked, and the load is applied to the coupling portion 35 of the arm portion 31 both when the connectors 3 and 5 are locked and unlocked. It prevents you from concentrating. Therefore, use of the connector device 1 can prevent the coupling portion 35 of the arm portion 31 from fatigue and deterioration (so-called fatigue).

A slit 47 is provided between the release operation portion 33 and the extension portion 37 . As a result, the movement of the release operation portion 33 in response to the pressing portion 49 pressed by the operator is less likely to be hindered by the extension portion 37, so that the locked portion 43 can be easily moved forward. Therefore, it becomes easy to release the engagement between the locking portion 29 and the locked portion 43 .

The arm portion 31 has a pair of left and right extension portions 37 which are coupled to the upper edge of the front surface of the housing body 25 via coupling portions 35 and extend downward, and the lower ends of the extension portions 37 extend in the left and right direction. It has a cross beam portion 39 to be connected. The release operation portion 33 is connected to the upper edge of the horizontal beam portion 39 and has a plate shape extending upward (in the direction opposite to the insertion direction). As a result, the arm portion 31 and the release operation portion 33 both extend in the vertical direction, and the arm portion 31 and the release operation portion 33 include portions that overlap each other when viewed in the horizontal direction. On the other hand, when the release operation portion 33 is extended in the forward direction of the insertion direction, the arm portion 31 and the release operation portion 33 do not overlap when viewed in the left-right direction. , the size of the latch portion 30 becomes larger than in the case where the two overlap each other. That is, by positioning the arm portion 31 and the release operation portion 33 so as to overlap each other in the left-right direction, the vertical length of the latch portion 30 can be reduced, and the connector device 1 can be miniaturized. .

In addition, the locked portions 43 are provided at both the left and right ends of the horizontal beam portion 39, respectively, and the locked portions 43 are arranged at positions separated from each other in the left-right direction. As a result, the latch portion 30 is joined to the header 9 at a location separated in the left-right direction. Therefore, the two connectors 3 and 5 are prevented from rattling, and the connection between the two connectors 3 and 5 is stably held.

In addition, the engaged portions 43 are provided so as to be substantially symmetrical in the lateral direction of the lateral beam portion 39 . As a result, the operator presses the pressing portion 49 to apply a load to the arm portion 31 substantially evenly on the left and right sides, thereby deforming the two connecting portions 35 substantially evenly, so that the locked portion 43 and the locking portion 29 are separated from each other. can be disengaged from the Therefore, in comparison with the case where the engaged portions 43 are provided offset in the horizontal direction of the horizontal beam portion 39, it is possible to prevent the load from concentrating on one of the connecting portions 35 when the lock is released. Deterioration due to use, particularly deterioration of the arm portion 31 due to separation of the two connectors 3 and 5, can be prevented.

When the plug-side connector 5 is inserted and engaged with the surface-mounted connector 3, the release operation portion 33 is received in the receiving recess 15A. As a result, the size of the connector device 1 in the coupled state can be reduced.

<<Second Embodiment>>

Therefore, the configuration of the projecting portion 145 will be described below, and the description of other portions will be omitted.

The projecting portion 45 of the connector device 101 according to the second embodiment is not provided on the release operation portion 33, but instead is provided on the header facing the release operation portion 33 when the connector device 101 is in the coupled state. It is provided on the front surface of the lateral side wall 15 on the front side of 9 . The protruding portion 145 is positioned above the engaging portion 29 and has a convex shape protruding forward. In this embodiment, the projecting portion 145 is formed as a ridge extending in the left-right direction. As shown in FIG. 7(C), it may be located behind the tip end surface 145A of the projecting portion 145 and the tip end surface 29B of the locking portion 29 .

Next, the operation of the connector device 101 will be described.

At this time, as shown in FIG. 7A, the protruding portion 145 may be in contact with the release operation portion 33 at the tip surface 145A. A gap 146 may be formed between it and the release operation portion 33 .

When the operator presses the pressing portion 49 rearward, as shown in FIG. 33 is the fulcrum and the lower end of the release operation portion 33 is the point of action, the lower end of the release operation portion 33 moves forward. As a result, the locked portion 43 moves forward of the locking portion 29 . As a result, the engagement between the locked portion 43 and the locking portion 29 is released. 6(A) to 6(C), the operator pulls the plug-side connector 5 upward to separate the plug-side connector 5 and the surface-mounted connector 3 from each other.

As shown in FIG. 7(B), the rearward load applied to the pressing portion 49 by the principle of leverage with the protruding end surface 145A of the protruding portion 145 as a fulcrum is a load that moves the lower end of the release operation portion 33 forward. , and the engagement between the locked portion 43 and the locking portion 29 can be released.
