Description

[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for mounting an electric component on a substrate together with an electric component to electrically connect the electric component to the substrate and to absorb a positional deviation from the electric component. The present invention relates to a floating connector that can move in a direction.

[0002]

2. Description of the Related Art When an electric component such as a rotary switch is mounted on a substrate, a connector is used to electrically connect the electric component to the substrate. This connector is mounted on a board on which electric components are mounted, and is electrically connected to the board. The electric component mounted on the board is connected to the connector, and is electrically connected to the board via the connector.

[0003] In mounting an electrical component using such a connector, a displacement may occur between the electrical component and the connector. The floating connector absorbs this displacement and facilitates the work of mounting the electric components.

FIG. 1 shows a conventional floating connector. The floating connector C includes a body 1 and a contact 3. The body 1 has a housing part 2 opened upward and forward. A contact portion 7 provided on a side surface of the body 6 of the rotary switch S as an electric component is inserted into the housing portion 2 from above. A plurality of contacts 3 are arranged in the width direction of the body 1. Each of the contacts 3 bent in an inverted U-shape is held by the body 1 with its upper portion sandwiching the back plate of the body 1. One of the vertical portions of the contact 3 is located on the front side of the back plate, and is bent forward in a U-shape so as to press against each terminal 8 of the contact portion 7 inserted into the housing portion 2 of the body 1. I have. The other vertical portion 4 located on the back side of the back plate has a horizontal portion in the middle, and a lower end portion protrudes below the body 1. The lower end is inserted into a terminal hole provided in the substrate and soldered.

[0005]

Such a conventional floating connector C can be mounted on a circuit board.
By bending the portion of the other vertical portion 4 of the contact 3 from the horizontal portion to the lower portion, the body 1 can move in any direction parallel to the plate surface of the substrate. Therefore, the displacement with the rotary switch S can be absorbed. However, soldering must be done from the back of the board. That is,
Since surface mounting is impossible, there are many inconveniences in mounting work.

An object of the present invention is to provide a floating connector that can be surface-mounted.

This floating connector is used to connect the above-described rotary switch S to a substrate P. A rectangular notch p into which the floating connector is fitted is provided at the edge of the board P.

The floating connector comprises a horizontally long rectangular parallelepiped body 10 and a plurality of contacts 20 held on the body 10 at intervals in the width direction of the body 10.

A resin body 10 is formed between a pair of side plates.
The first storage unit 11 thus formed has an upper part, and a first storage part
It has a second housing portion 12 formed integrally with the container portion 11.
That is, in the body 10, the first housing portion 11 and the second
It is formed integrally with the housing 12. 1st income
The contact portion of the rotary switch S described above is
The insertion part 7 is inserted from above. In front of the first housing 11
Is fully open except for both sides, and the opening
13 has a plurality of recesses into which the contacts 20 are fitted.
A part 14 is provided. Moreover, the back of the 1st accommodation part 11
The back plate 15 is provided with a slit extending in the vertical direction.
Openings 16 are provided in a plurality corresponding to the contacts 20
Have been. The back plate 15 has a plurality of vertical
The ribs 19 are reinforced.

The second accommodating portion 12 is divided into a plurality of small chambers by a plurality of partitioning plates 17 provided at intervals in the width direction of the body 10, and each of the small chambers accommodates a contact 20. The bottom of each chamber opens downward. Concave portions 18, 18 are provided on both sides of the second housing portion 12, and are opened on both sides of the body 10. Both edges sandwiching the cut p of the substrate P are fitted into the concave portions 18. The dimensions of the recesses 18 are determined such that the body 10 moves back and forth and right and left with both edges sandwiching the cut p of the substrate P fitted in the recesses 18.

The contact 20 is made of a narrow metal strip.
It is made of a thin plate, and has one U-shaped curved portion 21 in the center thereof.
Having. The bending portion 21 is connected to the second accommodation portion 12 of the body 10.

One end of the curved portion 21 is a horizontal portion 22 extending forward.
You. The other end of the curved portion 21 has a vertically extending vertical portion.
Part 24 is provided via a horizontal part 25 slightly extending forward.
Have been killed.

The horizontal portion 22 protrudes forward of the body 10 through the opening 13 of the body 10, and has its base fitted into the concave portion 14 provided on the bottom surface of the opening 13. The concave portion 14 has a configuration in which notches are provided on both side surfaces so as not to restrict the horizontal movement of the horizontal portion 22. The horizontal portion 22 is located on the front side of the substrate P in a state where both edges sandwiching the cut p of the substrate P are fitted into the concave portions 18 of the body 10. Bent downward so as to be inserted from above into the terminal hole.

The vertical portion 24 of the contact 20 is
The rotary switch S inserted into the first housing portion 11 of the “0” is bent forwardly so as to press against the terminal 8 of the contact portion 7 of the rotary switch S. The vicinity of the bent portion of the vertical portion 24 slightly projects forward in order to increase rigidity. Vertical part 2
The upper end 26 of 4 is led out to the back side of the back plate 15 from the slit-shaped opening 16 provided in the back plate 15 of the body 10 and is lightly pressed against the back surface thereof.

Next, a method of using the present floating connector will be described.

The body 10 is cut into the cut p of the substrate P from the side.
Is inserted into the concave portions 18 of the body 10, with both edges sandwiching the cut p of the substrate P. As a result, the body 10 is temporarily fixed to the substrate P, and subsequent mounting work is facilitated.

After the temporary fixing, the tip 23 of the horizontal portion 22 of the contact 20 is inserted into the terminal hole of the substrate P from above and soldered. At this time, the horizontal portion 22 is
Can be soldered from the front surface side of the substrate P because it protrudes forward of the body 10 along the surface of the substrate P. That is, surface mounting is possible.

When the mounting of the connector is completed, the rotary switch S is mounted on the surface of the substrate P,
Is inserted into the first housing portion 11 of the body 10 from above. As a result, the vertical portion 24 of the contact 20 is pushed into the slit-shaped opening 16, and the vertical portion 24 is strongly pressed against the terminal 8 of the contact portion 7 by the reaction force. At the same time, the upper end 26 of the vertical portion 24 is separated from the back surface of the back plate 15, and connection of a lead wire to the upper end 26 is facilitated.

Further, even if the tip 23 of the horizontal portion 22 of the contact 20 is soldered to the substrate P, the bent portion 21
, The horizontal portion 22 can freely move in the width direction of the body 10 and in the front-back direction. Therefore, the body 10 can move in any direction parallel to the plate surface of the substrate P.
Therefore, even if there is a displacement between the rotary switch S and the connector, the displacement is absorbed.

Thus, surface mounting of the floating connector becomes possible. Also, the horizontal portion 22 of the contact 20
If the tip 23 of the substrate P is extended downward, soldering can also be performed from the back side of the substrate P.
