Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a board-connecting connector used to electrically connect two boards using a connector.

[Conventional technology]

Conventionally, a connection structure as shown in FIG. 6 or 7 has been used to connect an FPC board and a printed circuit board. In the connection structure shown in FIG. 6, a spacer 5 made to be able to hold conductive rubber is disposed on the terminal portion 3 of the printed circuit board 1. A conductive rubber 7 is incorporated inside the spacer 5 . Terminal portions 11 of FPC board 9 are stacked on top of spacer 5 . Terminal part 3, 11
A hole 15 through which a screw 13 is passed is formed in the spacer 5 and the spacer 5 . The screws 13 are passed through these holes 15 and tightened, thereby attaching the FPC to the circuit board 1.
Fix the substrate 9. The screws 13 are also used for positioning the terminal parts 3 and 11 relative to each other. The terminal portions 11 of the FPC board 9 and the terminal portions 3 of the printed circuit board 1 are connected to each other by pressing the conductive rubber 7 against them.

Further, in the connection structure shown in FIG. 7, the terminal section 11 of the FPC board 9 is directly stacked on the terminal section 3 of the printed circuit board 1. Further, the terminal portions 3 and 11 are sandwiched between two presser fittings 22 and 23 with a cushion material 20 in between. Holes 15 are formed in the cushion material 20, the terminal parts 3 and 11, and the presser fittings 22 and 23, respectively, through which the screws 13 are passed. After the cushion material 20 and the two terminal parts 3 and 11 are sandwiched between the presser fittings 22 and 23, the screws 13 are inserted into the holes 15 and tightened. The screws 13 are also used for positioning the terminal parts 3 and 11 relative to each other.

The two types of connection structures shown in FIGS. 6 and 7 have different components, but the basic connection method is the same because screws are used. Other connection structures include those in which the terminal portions 11 of the FPC board 9 are directly soldered or welded onto the terminal portions 3 of the printed circuit board 1.

[Problem that the invention attempts to solve]

However, the terminal parts 3 and 11 by the screws 13
In this connection structure, if the pitch of the terminal parts 3 and 11 is narrow, it will take more man-hours to assemble and remove, and since there are many parts, there will be problems such as loss or incorrect assembly, fluctuations in screw tightening strength, forgetting to tighten screws, etc. There is a problem of doing this.

Furthermore, during assembly, care must be taken to avoid short-circuiting due to metal pieces being pinched, and there is a problem in that if conductive rubber 7 or the like is used, the contact resistance will increase.

Furthermore, a hole 1 for passing the screw 13 through the terminal portions 3 and 11 is provided.
5 or if holes 15 cannot be made in the substrates 1 and 9, it is difficult to position the substrates 1 and 9.

Therefore, an object of the present invention is to provide a board-connecting connector that can reduce assembly man-hours and allow boards to be connected, removed, and aligned through simple operations.

[Means and actions for solving problems]

According to the present invention, in a board connecting connector for connecting two boards, an insulator has two board insertion spaces parallel to each other that receive the boards, and the insulator has two board insertion spaces. It includes a conductive contact installed so as to be located between the spaces, and a slider slidably installed in the insulator, and the contact is made in a flat plate shape, and the contact is formed into a flat plate, and the contact is inserted into the space for inserting the two boards. The slider integrally includes two spring pieces that respectively penetrate into the substrate, and the spring pieces have contact protrusions facing the substrate, and the slider deflects the spring pieces toward each other and in the board width direction. There is obtained a board-connecting connector characterized in that the contact protrusion is brought into contact with the board by pressing the spring piece and restoring the spring piece.

If the spring piece of the contact is pushed out of the board insertion space by the slider, the contact will not come into sliding contact with the spring piece when the board is inserted into or removed from the board insertion space.

〔Example〕

FIGS. 1 and 2 show an embodiment of the board-connecting connector of the present invention.

The illustrated board connection connector has an insulator including an outer insulator 31 and an inner insulator 33 built into the outer insulator 31. An FPC board 3 is installed between the outer insulator 31 and the inner insulator 33.
5 and a printed circuit board 37, parallel to each other.
9 and 40 are formed. Two insulating sliders 42 and 43 are incorporated into the opening on one side of the outer insulator 31. Holes 45 and 46 for receiving the FPC board 35 and the printed circuit board 37 are formed on the other side of the outer insulator 31.

Further, inside the outer insulator 31, a conductive contact 48 made in a flat plate shape is provided. The contact 48 is installed adjacent to the two board insertion spaces 39 and 40. That is, the contact 48 is connected to the two board insertion spaces 3.
It integrally includes two spring pieces 51 that penetrate into the spring pieces 9 and 40, respectively, and a connecting portion 52 that connects these spring pieces 51, and is formed into a substantially U-shape.

At the tip of the spring piece 51, there are sliders 42, 43.
A protrusion 56 corresponding to the protrusion 53 is formed. In the middle part of each spring piece 51, there is an FPC board 35 inserted into the two board insertion spaces 39 and 40.
A contact protrusion 58 for contacting a terminal portion of the printed circuit board 37 is also formed.

As shown in FIG. 3, the spring pieces 51 are installed between a plurality of partition walls 61 formed parallel to each other on the upper and lower surfaces of the inner insulator 33.

A pair of simple locks 63 are formed on both end faces of the inner insulator 33. These simple locks 63 serve to lock the outer insulator 31 and the inner insulator 33.

Next, the FPC board 35 and the printed circuit board 37
The operation of connecting the board to the board connection connector will be explained.

First, connect the contact 4 to the inner insulator 33.
Insert 8. At this time, the contact 48 is only hooked onto the inner insulator 33. After the contacts 48 are inserted between the partition walls 61, the outer insulator 31 is fitted into the inner insulator 33. At this time, the simple lock 63 of the inner insulator 33 engages with the outer insulator 31, so that the inner insulator 33 and the contact 48 cannot be removed.

Next, the two sliders 42 and 43 are fitted into the opening of the outer insulator 31. Slider 4
2 and 43 are engaged by a simple lock 65 formed on the outer insulator 31 and cannot be removed.

The contact 48 is the inner insulator 33,
Outer insulator 31 and sliders 42, 43
It is sandwiched between the two to prevent it from coming off. Moreover, in this state, the sliders 42 and 43 are preloading.

In this state, when inserting the FPC board 35 or the printed circuit board 37, a tool such as a screwdriver is inserted into the groove 74 formed at the open end of the outer insulator 31 and rotated to pull out the sliders 42, 43. FIG. 4 shows a state in which only one slider 42 is pulled out. Slider 4
2, 43, the protrusion 5 of the contact 48
6 is pushed by the protrusions 53 of the sliders 42 and 43, and as a result, the spring piece 51 is deflected in a direction toward the inner insulator 33. That is, the spring piece 5
1 is held down by sliders 42 and 43 while being bent in the board width direction. Therefore, FPC board 3
5 or printed circuit board 37 through holes 45, 46
Even if the contact 48 is inserted, the contact 48 is not contacted, so the insertion is easy. Therefore, it can be inserted into the board insertion spaces 39, 40 through the holes 45, 46 of the outer insulator 31 without damaging the FPC board 35 or the printed circuit board 37.

FPC board 35 or printed circuit board 37
After the insertion is completed, as shown in FIG. 5, when the sliders 42 and 43 are pushed back by hand, the contacts 48
Due to the restoring force of the spring piece 51, the printed circuit board 3
7 or the contact protrusion 48 comes into contact with the FPC board 35.

FPC board 35 or printed circuit board 37
If only one of the substrates is inserted, one of the substrates is held by the contacts 48 because the spring pieces 51 contact and support the sliders 42 and 43 on the vacant side.

Further, the sliders 42 and 43 are designed so that they can be operated with a tool such as a screwdriver, considering that the board connection connectors are small and difficult to handle by hand.

[Effect of idea]

As explained above using the embodiments, according to the board connection connector of the present invention, the board can be positioned and inserted into the connector with zero force by operating the slider, so insertion is easy and the board is not damaged. There is no. Furthermore, since the contacts are surrounded by an insulator, there is no risk of contact with an external conductor or short circuit, and the contact resistance is lower than that of conventional conductive rubber.

Furthermore, the board connection connector requires fewer parts to assemble, eliminating the risk of losing parts, and
Even if one side of the board is removed, the other side of the board does not come off, so assembly is easy.
