Japanese Patent Laid-open No. 2000-100501

  However, in the conventional floating connector, the plug-in connector has two parts, a connector body and a holding member. As a result, the number of components increases, and the labor of component management increases. Further, the mounting area on the printed board increases, which becomes an obstacle to high-density mounting of the printed board. The floating connector according to the present invention has been proposed in order to solve such a problem.

The gist for solving the above-described problems of the floating connector according to the present invention is to provide a fixed-side insulator fixed to a printed circuit board, a base fixed to the fixed-side insulator, and a tip. A plurality of contacts protruding from the fixed-side insulator, and a movable-side insulator fitted with a mating connector while the tip of the contact is fixed, the fixed-side insulator and the The movable-side insulator is integrally formed by a narrow swing connecting portion extending from these side walls, and the movable-side insulator is swingably supported with respect to the fixed-side insulator. That is.
Further, the contact has a press-fitting step where a base part and a tip part of the contact are made parallel to each other along the longitudinal direction, and a tip part of a press-fitting jig that presses along the longitudinal direction is in contact with the middle part Is provided.

According to the floating connector of the present invention, since the fixed-side insulator and the movable-side insulator are integrally formed by the swing connecting portion, the number of parts is reduced and parts management is facilitated.
Thereby, the size of the both insulators can be designed compactly as a whole, the board mounting area can be reduced, and it is suitable for high-density mounting.
Further, in the past, the contacts were separately press-fitted into the fixed-side insulator and the movable-side insulator, but with the floating connector according to the present invention, it is possible to press-fit the contacts into both the above-described insulators at once. It is possible to reduce the press-fitting process and the conveying process between them, thereby shortening the manufacturing period.
By providing a step in the contact, a press-fitting jig formed so as to come into contact with the step shape is prepared, and the contact is press-fitted into the fixed-side insulator and the movable-side insulator at a time. It becomes possible to do.

  As shown in FIGS. 1 and 2, the floating connector 1 according to the present invention includes, for example, a fixed-side insulator 3 fixed to a printed circuit board 2 for high-density mounting, and a base 4a on the fixed-side insulator 3. A plurality of contacts 4 which are fixedly provided and have tip portions 4b projecting from the fixed-side insulator 3, and movable-side insulation in which the tip portions 4b of the contacts 4 are fixed and fitted with a mating connector. A body 5 and a hold down 6 provided for mounting and fixing to the printed circuit board 2 and soldered with metal.

  Further, the fixed-side insulator 3 and the movable-side insulator 5 are narrow side walls extending from the front end portion or the rear end portion of each side wall, for example, the side walls of the left and right end portions in the longitudinal direction. Are formed integrally by the swing connecting portion 7.

  The swing connecting portions 7a to 7d are formed with a narrow width so as to easily swing, and are provided at four locations along the front-rear direction. The reason for extending the distance from the front end portion or the rear end portion of the left and right side walls facing each other is to make it easier to swing by making the swing connecting portion 7 as long as possible. It is not limited to extending from the left and right side walls, and the oscillating connecting portion may be extended from the front and rear side walls facing each other. Further, if possible, it may extend from the left and right side walls to the front and rear side walls. In short, any structure may be used as long as the movable-side insulator 5 can swing vertically and horizontally with respect to the fixed-side insulator 3.

  In this way, the movable-side insulator 5 is supported integrally and swingably with respect to the fixed-side insulator 3 via the swing connecting portion 7. As described above, since the insulators 3 and 5 are integrated, in order to press-fit and fix the contact 4 to this, it is not only necessary to press with a jig. As shown in FIG. 3, the contact 4 has a thin plate thickness and is bent in a complicated manner. Therefore, when only the pressing end surface 4c is pressed, the contact 4 is bent against the resistance caused by the press-fitting.

  Therefore, in order to reliably perform the press-fitting of the contact 4, as shown in FIGS. 3 to 4A and 4B, the base 4a and the tip 4b are parallel along the longitudinal direction. In addition, a press-fitting step 4d with which the tip of the press-fitting jig 8 that presses along the longitudinal direction abuts is provided in the middle of the step to be offset.

  Corresponding to the step 4d of the contact 4, the press-fitting jig 8 also includes the pressing end surface 4c of the contact 4, the step 4d and the tip 4a, as shown in FIGS. A step 8a is provided so as to come into contact with the front end face of the S-shaped bent portion. With the press-fitting jig 8, the contact 4 can be simultaneously press-fitted into the contact housing hole of the fixed-side insulator 3 and the contact housing hole of the movable-side insulator 5. The end portion of the base portion 4a is soldered to the printed circuit board 2, and the contact of the mating connector is slidably contacted with the rectangular flat plate-like tip portion 4b.

  Further, the contact 4 is formed integrally with the fixed insulator 3 and the movable insulator 5 via the oscillating connecting portion 7 so that the whole becomes compact. The length of the direction is also shortened. Then, the distance between the base portion 4a and the tip portion 4b is shortened, the length of the movable portion of the contact 4 when floating is shortened, and its rigidity is increased, so that the movable amount with respect to the external force is increased. Decrease. In order to avoid this, as shown in FIGS. 4 (A) and 4 (B), a slit 4e is provided in the front end portion 4b of the rectangular flat plate, for example, in the vicinity of the end portion along the front-rear direction, so The length a of the part is secured long. As a result, the tip 4b of the contact 4 can be easily swung vertically and horizontally (in the plate thickness direction) with respect to the base 4a when the contacts are swung together.

  If the floating connector 1 according to the present invention is used, for example, as shown in FIG. 5, the floating connector 1 is a male connector, its contact 4 is a right angle type, and this printed circuit board 2 is a mounting board. The female connector 14 mounted on the printed circuit board 9 in the orthogonal direction is fitted with a fork-type contact. The movable insulator 5 of the floating connector 1 is swung up and down and left and right by the swing connecting portion 7 to absorb the position error at the time of fitting, and the connectors of the printed circuit boards 2 and 9 are smoothly fitted. Is done.

  6, when the printed circuit boards 2 and 9 are parallel to each other, the floating connector 1 is a male connector whose contacts 4 are soldered straight to the printed circuit board 2, Even if there is a position error when mated with the female connector 14, the movable insulator 5 swings up and down, left and right as described above, absorbs the position error, and fits smoothly.
