Description of the Related Art When mounting an electrical connector for surface mounting on a printed circuit board, there must be no misalignment between a pad of the printed circuit board and a terminal of the connector. For this reason, in the conventional surface mount electrical connector, a part of the mounting portion formed at both ends of the housing is projected as a positioning projection toward the printed circuit board, and the projected positioning projection is printed in advance. The surface mounting electrical connector is positioned on the printed circuit board by being fitted into a positioning hole formed in the circuit board.

When the surface-mounting electrical connector described above is fitted to the receptacle-type surface-mounting electrical connector, the displacement is absorbed by the floating function.

必要として好ましいものでない。According to such a conventional surface mount electrical connector, a problem occurs when the surface mount electrical connector is arranged in parallel on a printed circuit board with a gap. That is, in such an electrical connector for surface mounting, a plurality of terminals (for example, 90 poles) are arranged at a predetermined pitch along the longitudinal direction of the housing. The distance between the pitches of the positioning protrusions formed at both ends in the longitudinal direction becomes longer. According to this, when positioning the housing by inserting the positioning protrusion of the housing into the positioning hole formed in the printed circuit board,
Even if the gap in those insertion parts is small,
Because the distance between the pitches of the positioning protrusions is long, a displacement in the longitudinal direction of the housing occurs, and therefore, the adjacent surface mount electrical connectors cannot be accurately arranged in parallel on the printed circuit board. there were. That is, an accurate parallel state cannot be obtained in the plug type surface mount electrical connector arranged on one side of the printed circuit board, and an accurate parallel state cannot be obtained in the receptacle type surface mount electrical connector arranged on the other side of the printed circuit board. A parallel state could not be obtained. In such a state,
When the plug type surface mount electrical connector mounted on one side of the printed circuit board is mated with the receptacle type surface mount electrical connector mounted on the other side of the printed circuit board, the mating is performed well. And the terminals of the electrical connectors may not contact each other as predetermined. In addition, if these fittings are forcibly performed, an unexpected load is applied to the soldered portion between the pad of the printed circuit board and the terminal of the connector, which may cause solder cracking, breakage, and bending of the terminal. There is.
By increasing the diameter of the positioning hole of the printed circuit board in comparison with the size of the positioning protrusion of the housing, it is possible to arrange the surface-mounting electrical connector at an appropriate position. After the positioning projection is inserted, it is necessary to adjust the parallel state of the two adjacent surface mount electrical connectors again, which is not preferable because it requires a large number of man-hours.

The connector is complicated because it needs to be devised so that it can flexibly and elastically deform the terminals and the mounting portion and the housing mounted on the housing. Further, when assembling the surface mount electrical connector, the terminals are connected to the housing. However, there is a disadvantage that the terminal must be flexibly attached to the housing, and it is difficult to assemble the terminal to the housing.

The shape of the fitting portions 10A and 10B of the positioning and fixing member 9 is not limited to the above-described embodiment, and can be appropriately selected.
A and 10B can be easily attached to and detached from the fitting recess 5, so that the maintainability of the surface mount electrical connector can be improved. The positioning and fixing member 9 has the same shape as the fitting recess 5 formed in the housing H of the receptacle type surface mount electrical connector and the fitting recess formed in the housing of the plug type surface mount electrical connector. According to this, it is possible to use a single positioning and fixing member 9 common to both.

ネクタとの相対位置を正確に平行状態に固定できる。In the second embodiment shown in FIG. 2, a fitting projection is formed on one side wall 4 and the other side wall 8 of the housing H so as to protrude from the wall and extend along the depth direction of the housing H. The positioning fixing member 11 has fitting recesses serving as fitting portions 12A and 12B fitted to the fitting protrusions 10 of the housing H at both ends in the longitudinal direction WW. By fitting the fitting portions 12A and 12B of the positioning and fixing member 11 to the fitting projections 10 of the housing H, the first surface-mounting electrical connector is formed in the same manner as in the previous embodiment. The relative position between the second connector and the second surface-mounting electrical connector can be accurately fixed in a parallel state.

となり製造コストの低減を達成できたものである。As described above, according to the electrical connector for surface mounting according to the present invention, the first electrical connector for surface mounting and the second electrical connector for surface mounting which are arranged adjacently with a gap therebetween are different from each other. The fitting recess or fitting protrusion provided on one side wall surface of the housing is fitted by a pair of fitting portions of the positioning and fixing member, and the fitting recess or fitting projection provided on the other side wall surface of the housing is connected to another fitting portion. The first surface mounting electrical connector and the second surface mounting electrical connector are accurately placed on the printed circuit board with a certain gap along the longitudinal direction because they are fitted by the pair of fitting portions of the positioning and fixing member. It is fixed in parallel. Thus, the receptacle-type surface-mounting electrical connector arranged in parallel on one side of the printed circuit board and the plug-type surface-mounting electrical connector arranged in parallel on the other side of the printed circuit board are fitted. When fitted, the fitted terminals are connected well and do not cause any trouble to the soldered portions of the terminals, and the reliability can be greatly improved. Further, since it is not necessary for the surface mount electrical connector to have a floating function, the structure is simple, the assembly is easy, and the production cost can be reduced.
