The present invention relates to a surface mount connector formed in the above.

When a surface mount component is mounted on a printed circuit board that constitutes an electronic device, the head of the surface mount component automatic mounting machine holds a predetermined surface mount component that is stored or taped in a magazine, It is necessary to transport to the position. At this time, without preparing a head of a surface mounting component automatic mounting machine that is aligned with each of a variety of complex outer shapes and surface mounting components of various outer dimensions, a flat portion is provided on the upper surface of the surface mounting component, A system is applied in which the flat portion is sucked by a component transport suction nozzle provided at the tip of a head of a surface mount component automatic mounting machine and transported to a predetermined position on a printed wiring board.

FIG. 2A is an external perspective view showing an embodiment of a conventional receptacle for a connector mounted on a printed wiring board, and FIG. 2B is a side view. The receptacle 11 forms a box-shaped housing having four side surfaces including a housing side wall 12 and a bottom surface made of a plastic member, and the top surface is open so that a connector plug can be inserted. Contacting the plurality of conductive paths printed on the tape-shaped FPC (F lexible P rinted C able ) 16 which is inserted into the opening of the top surface of the receptacle 11, a metal member having a power spring of for making electrical connection A number of FPC contacts (not shown) configured by the above are accommodated in the receptacle 11, and each contact is led to a corresponding soldering terminal 15 disposed on the bottom of the housing. Reference numeral 17 shown in FIG. 2B denotes an FPC gripping part for holding the FPC so as not to damage the flexible FPC when the FPC is inserted and removed.

In the connector part, since the plug is inserted from the upper part of the receptacle, the upper part of the receptacle needs to have an open structure as a moving path of the plug. Accordingly, it becomes impossible for the component transport suction nozzle of the surface mount component automatic placement machine to suck the top surface of the receptacle, which is a surface mount component, and transport it to a predetermined position on the printed wiring board. In order to solve this problem, a device has been devised in which a suction assisting tool having a detachable structure is mounted by using Japanese Utility Model Laid-Open No. 5-31188. Furthermore, as seen in Japanese Patent Laid-Open No. 9-115591, a partition is provided near the center of a number of terminal rows in the receptacle, and a suction nozzle for component transportation of a surface mount component automatic mounting machine can contact the upper surface of the partition. A device with a suction surface has been devised.

On the other hand, in Japanese Patent Application Laid-Open No. 9-115591, a partition is provided near the center of a large number of terminal rows in a receptacle, and the upper surface of the partition is sucked by a component transport suction nozzle of a surface mount component automatic mounting machine, and printed on a printed wiring board. In order to convey to a predetermined position, it is necessary to make the width dimension of the partition larger than at least the outer diameter of the component conveying suction nozzle. Terminals cannot be arranged in the receptacle in which the partition exists, and this is a problem particularly in a small connector that requires high-density mounting of components.

Therefore, as in the first embodiment according to the prior art shown in the external perspective view of FIG. 3A and the side view of FIG. Adhering to the upper surface of the receptacle 21 including the upper end surface, the component transporting suction nozzle of the surface mounting component automatic mounting machine sucks the suction film 23 adhered to the upper surface of the receptacle 21 as the surface mounting component. Thus, a means for carrying the receptacle 21 to a predetermined position on the printed wiring board has been put into practical use. When the receptacle 21 is mounted on the printed wiring board, the top surface of the receptacle 21 needs to be opened in order to insert the connector plug into the receptacle 21, and the suction film 23 is peeled from the receptacle 21. The work requires work, and the peeled adsorption film 23 becomes unnecessary and is discarded, so that the waste increases the burden on the global environment.

4A and 4B show a second embodiment of the prior art. FIG. 4A is an external perspective view, and FIG. 4B is a side view. The suction cover 33 is inserted between the housing side wall 32 and the inner surface of the opposite housing side wall, the receptacle 31 and the suction cover 33 are locked together, and the component mounting suction nozzle of the surface mount component automatic mounting machine is The suction cover 33 locked to the top surface of the receptacle 31 which is a surface mount component is sucked and transported to a predetermined position on the printed wiring board.

When the receptacle 31 is mounted on the printed wiring board, the top surface of the receptacle 31 needs to be opened in order to insert the connector plug into the receptacle 31. The first embodiment of the prior art described above Similarly, the suction cover 33 is removed from the receptacle 31, and the removed suction cover 33 is discarded, increasing the load on the global environment.

In order to suck the receptacle of the surface mount connector by the component transfer suction nozzle of the surface mount component automatic placement machine and transport it to a predetermined position on the printed wiring board, a partition is provided at the center of the numerous terminal rows in the receptacle, In the means according to the prior art having a suction surface that enables contact by the component transport suction nozzle of the surface mount component automatic mounting machine to the upper top surface of the partition, the width dimension of the partition is at least the outer diameter of the component transport suction nozzle. Need to be bigger than. A connector terminal cannot be provided in a portion in the receptacle where the partition exists, and this causes a problem particularly in a small connector that requires high-density mounting of components.

Also, as means for solving the above problems, sticking of a film for suction as means for providing a suction surface by a suction nozzle for conveying parts on the upper end surface of the housing side wall of the receptacle, or arranging a cover for suction prints the receptacle. After being mounted at a predetermined position on the wiring board, it becomes an unnecessary object, and it is necessary to remove the suction film or the suction cover, and disposal of the removed unnecessary substance causes an increase in the load on the global environment.

In a surface-mounting connector in which a plug is inserted into a receptacle from above, when the receptacle is mounted on a printed circuit board by a surface-mount component automatic mounting machine, the suction surface with which the component transporting suction nozzle abuts is one side in the longitudinal direction of the receptacle. The upper side of the housing side wall is shared and integrally molded at the substantially central position of the housing side wall so that it can be bent along the adsorption surface and the boundary line of the housing side wall. A protrusion is formed on the opposite side of the boundary line to be formed, and the suction surface can be locked by the protrusion on the other side wall in the longitudinal direction of the receptacle housing when the suction surface is bent along the boundary line.
