Further, the conductive shell 22 is formed with a ground terminal 28 (FIG. 4) connected to the ground connection portion of the wiring pattern portion provided on the substrate to which the board-side connector device 20 is attached.

In such a board-side connector device 20, one end of each of the plurality of connection terminals 24 is connected to a wiring pattern portion provided on a board to which the board-side connector device 20 is attached, and is provided on the conductive shell 22. The ground terminal 28 thus connected is connected to the ground connection portion of the wiring pattern portion provided on the board to which the board-side connector device 20 is attached, and the board is electrically connected to the electric circuit component provided thereon. Made and installed.

As shown in FIGS. 3 and 4, the connector device 11 and the board-side connector device 20 described above are configured such that the board-side connector device 20 is provided on a board 30 that is a solid printed wiring board, for example. The fitting projection 15 in the connector device 11 is inserted into the fitting depression 23 in the board-side connector device 20 and is fitted in a state where the electrical connection with the connector is made and attached, As a result, the connector device 11 is fitted into the board-side connector device 20. In FIG. 3, the connector device 11 and the board-side connector device 20 are such that one end portion in the longitudinal direction of the insulating housing 13 and one end portion in the longitudinal direction of the insulating housing 21 are cut away to show a cross section. .

As shown in FIGS. 3 and 4, when the fitting convex portion 15 in the connector device 11 is inserted into the fitting concave portion 23 in the board-side connector device 20 to be fitted, the line VV in FIG. As shown in FIG. 5 showing a cross section and FIG. 6 showing an enlarged portion including the cross section shown in FIG. 3, the engagement holes 18 and tabs 19 in the lever-like portion 17 provided in the connector device 11 are provided. The provided portion enters the inside of the portion provided with the engaging protrusion 26 in the engaging portion 25 provided in the board-side connector device 20. As a result, the engagement hole 18 in the lever-like portion 17 is engaged with the engagement protrusion 26 in the engagement portion 25, and as a result, in the board-side connector device 20 of the fitting convex portion 15 in the connector device 11. The fitting state with the fitting recess 23 is stably maintained.

At this time, as shown in FIG. 6 and FIG. 7 showing an enlarged view of the inside of the circle VII in FIG. 4, the tab 19 provided in the lever-like portion 17 provided in the connector device 11 has the tip thereof. The surface portion is brought into contact with a locking portion 27 provided on the board-side connector device 20, and the locking portion 27 is caused to undergo elastic deformation that is displaced outward along the longitudinal direction of the insulating housing 21 of the board-side connector device 20. . That is, the locking portion 27 is elastically deformed in a direction substantially parallel to the surface of the substrate 30. Thus, the engaging portion 27 that has been elastically deformed and displaced outward is maintained in a state in which the fitting convex portion 15 in the connector device 11 is engaged with the fitting concave portion 23 in the board-side connector device 20. Under the circumstances, the tab 19 provided on the lever-like portion 17 is maintained in a state of being displaced outward.

When the fitting convex portion 15 in the connector device 11 is inserted into the fitting concave portion 23 in the board-side connector device 20 to be fitted, the plurality of conductive contacts 16 arranged in the connector device 11 are arranged. Each of the portions arranged on the fitting convex portion 15 is contact-connected to a corresponding one of the plurality of connection terminals 24 arranged on the board-side connector device 20 and electrically connected to the board 30. Thus, the plurality of conductive contacts 16 are respectively connected to the plurality of connection terminals 24 in the board-side connector device 20. Thereby, each signal conductor of the plurality of coaxial cables 12 connected to each of the plurality of conductive contacts 16 passes through the conductive contacts 16 and the connection terminals 24 in the board-side connector device 20, and the wiring pattern portion provided on the substrate 30. The ground conductors of the plurality of coaxial cables 12 connected to the conductive shell 14 of the connector device 11 are provided on the conductive shell 14 and the conductive shell 22 of the board side connector device 20. The ground terminal 28 is connected to a ground connection portion of the wiring pattern portion provided on the substrate 30.

Thereafter, the fitting state of the fitting convex portion 15 in the connector device 11 with the fitting concave portion 23 in the board side connector device 20 is released, and the fitting convex portion 15 in the connector device 11 is fitted in the board side connector device 20. When being detached from the recess 23, as shown in FIGS. 8 and 9, the lever-like portion 17 provided in the connector device 11 has, for example, the board-side connector device 20 attached to the end thereof. A pressing force that pushes down toward the substrate 30 is applied, and elastic deformation occurs, causing displacement in the direction toward the substrate 30. Accordingly, as shown in FIG. 10 showing a cross section taken along line XX in FIG. 9, the engagement hole 18 in the lever-like portion 17 displaced in the direction toward the substrate 30 is formed in the substrate 30 of the lever-like portion 17. Along with the displacement in the direction toward, it is displaced in the direction toward the substrate 30, and the engagement with the engagement protrusion 26 in the engagement portion 25 provided in the substrate-side connector device 20 is released. As a result, the fitting convex portion 15 in the connector device 11 can be released from the fitting concave portion 23 in the board-side connector device 20 by releasing the fitting state with the fitting concave portion 23 in the board-side connector device 20. It is said. That is, the connector device 11 is in a state where the fitting convex portion 15 can be pulled out from the fitting concave portion 23 in the board-side connector device 20 and detached from the board-side connector device 20.

Further, at this time, as shown in FIG. 11 and FIG. 12 showing an enlarged view of the inside of the circle XII in FIG. 9, the tab 19 provided in the lever-like portion 17 provided in the connector device 11 has a lever-like shape. With the displacement of the portion 17 in the direction toward the substrate 30, it is displaced in the direction toward the substrate 30, and from the state where the front end surface portion comes into contact with the locking portion 27 provided in the board side connector device 20, the locking portion 27, the position on the substrate 30 side. The locking portion 27, which the front end surface portion of the tab 19 is not in contact with, is automatically restored by its own elasticity from a state in which it is elastically deformed and displaced outward, and takes a position closer to the substrate 30 than the locking portion 27. The tab 19 is locked to prevent the tab 19 from returning to its original position. Thereby, the lever-like portion 17 displaced in the direction toward the substrate 30 is temporarily prevented from being restored, and is maintained at the position displaced in the direction toward the substrate 30.

In this way, the tab 19 is locked by the locking portion 27 and the lever-shaped portion 17 is maintained at the position displaced in the direction toward the substrate 30, for example, the end of the lever-shaped portion 17. Even if the pressing force to push it down toward the board 30 is not applied, the engagement hole 18 in the lever-like part 17 is engaged with the engagement protrusion 26 in the engagement part 25 provided in the board-side connector device 20. Is maintained in the released state. Therefore, for example, once a pressing force is applied to the end of the lever-shaped portion 17 to push it down toward the substrate 30, the connector device 11 can be fitted without requiring the pressing force to be continuously applied. The convex portion 15 can be pulled out from the fitting concave portion 23 in the board-side connector device 20, and the connector device 11 can be detached from the board-side connector device 20.

Then, when the fitting convex portion 15 of the connector device 11 is pulled out from the fitting concave portion 23 in the board-side connector device 20 and the connector device 11 is detached from the board-side connector device 20, a lever-like portion provided in the connector device 11 is obtained. 17, the portion provided with the engagement hole 18 and the tab 19 is pulled out from the inside of the portion provided with the engagement protrusion 26 in the engagement portion 25 provided in the board side connector device 20, and the tab 19 is locked. The portion 27 is not locked. Thereby, the lever-like portion 17 is automatically restored by its own elasticity from a state in which the lever-like portion 17 is elastically deformed and displaced in the direction toward the substrate 30.

In the connector device 11 described above, the fitting convex portion 15 is integrated with the conductive shell 14 while being fitted with the fitting concave portion 23 of the board-side connector device 20 attached to the board 30. In order to displace the lever-shaped portion 17 formed in the direction toward the substrate 30 to which the board-side connector device 20 is attached, for example, a simple operation of pushing and moving the lever-shaped portion 17 in the direction toward the substrate 30 is sufficient. In such an operation, in order to perform an operation with another connector or other electrical component disposed adjacent to the board-side connector device 20 on the surface of the board 30 to which the board-side connector device 20 is attached. No space is required for placing a finger or a predetermined tool. Therefore, according to the connector device 11, the fitting convex portion 15 is brought into a fitting state with the fitting concave portion 23 of the board-side connector device 20 attached to the board 30, and is provided in the lever-like portion 17. 18 is engaged with an engagement protrusion 26 provided on the board-side connector device 20, and is arranged adjacent to the board-side connector device 20 on the surface of the board 30 to which the board-side connector device 20 is attached. Fitting of the engagement hole 18 with the engagement protrusion 26 without requiring a space for placing a finger or a predetermined tool between the other connector or other electrical component to be operated Can be easily released. As a result, the connector device 11 can improve the utilization efficiency of the substrate 30 to which the substrate-side connector device 20 is attached, and can contribute to the downsizing of the substrate 30.

Further, according to the connector device 11, the lever-like portion 17 formed integrally with the conductive shell 14 causes a displacement in the direction toward the substrate 30 to which the substrate-side connector device 20 is attached, causing elastic deformation thereof. Therefore, after the lever-shaped portion 17 is displaced in the direction toward the substrate 30 to which the board-side connector device 20 is attached, the operation for restoring it is not required.

Furthermore, according to the connector device 11, the fitting convex portion 15 is elastically deformed toward the substrate 30 while being fitted with the fitting concave portion of the board-side connector device 20 attached to the substrate 30. The lever-like portion 17 displaced in the direction can be displaced by elastic deformation in a direction substantially parallel to the surface of the substrate 30 by providing a tab 19 provided on the substrate-like connector device 20 on the lever-like portion 17. Since the restoration is temporarily prevented by being locked by the locking portion 27, the lever-shaped portion 17 is directed toward the substrate 30 when the fitting convex portion 15 is detached from the fitting concave portion 23. The operation of displacing in the direction is not required to be performed continuously, and the fitting convex portion 15 can be easily detached from the fitting concave portion 23.

Further, in the connector device 11, the lever-like portion 17 for displacing the lever-like portion 17 formed integrally with the conductive shell 14 in a direction toward the substrate 30 to which the board-side connector device 20 is attached. A simple operation of pushing the lever in the direction toward the substrate 30 can be performed directly on the lever-shaped portion 17. For example, it is not necessary to attach an operation portion made of an insulating member to the lever-shaped portion 17. Therefore, the operation of the lever-like part 17 causes a disadvantage that the lever-like part 17 slides between the lever-like part 17 and the operation part attached thereto, thereby causing the operation part to wear out. Absent.

The apparatus may be such that the lever-like portion is provided with an engagement hole, an engagement recess, or an engagement protrusion provided in the engagement portion of the board-side connector device. Also in such a case, the same effect as the effect obtained by the connector device 11 described above can be obtained.

Further, in the connector device 11 described above, the lever-like portion 17 is formed when the fitting convex portion 15 is in a fitted state with the fitting concave portion 23 of the board-side connector device 20 attached to the board 30. Is displaced in a direction toward the substrate 30 to which the board-side connector device 20 is attached, whereby the engagement portion 25 in the board-side connector device 20 of the engagement hole 18 as the engagement means provided in the lever-like portion 17. It is assumed that the engagement with the engagement protrusion 26 as the engagement means provided in is released.
