Abstract

PURPOSE:To obtain a connector that can be used for lower surface connection as well as for upper surface connection, and to obtain a connector that can vertically be mounted by reversing the connector. CONSTITUTION:A connector has a base insulator 21 and a conductive contact 23 that is held by the insulator. A sliding insulator 31 and a flexible print board 33 are inserted in or removed from an opening part 29 of the base insulator 21. By the insertion, the flexible print board 33 is pushed to a contact part 23e, and comes into contact therewith. A lower surface connection type is thus obtained for connecting a conductor part 33a of the flexible print board 33 to the contact part 23e. In order to connect to the contact part 23e with the conductor part 33a of the flexible print board 33a as an upper surface, the connector is reversed and is used. By changing the contact 23, the contact can thus be used as a vertical mounting type connector.

The slide insulator 7 can be fitted into and removed from a large opening 9 formed on the other side of the base insulator 3.

These connectors are installed on one side of an attachment target board 11 such as a printed circuit board. That is, the base insulator 3 has a lower surface 3a or an upper surface 3b parallel to the uniaxial direction so as to face the mounting target substrate 11.

The connector shown in FIG. 12 is a bottom contact type connector in which the conductor portion of the flexible printed circuit board 5 is brought into contact with the contact portion 1b as the bottom surface. The terminal portion 1a is incorporated into the base insulator 3 so that it can be grounded to one side of the mounting target board 11.

[Embodiment] FIGS. 1 to 4 show a connector according to an embodiment of the present invention.

Referring to FIGS. 1 to 4, this connector has a base insulator 21 and conductive contacts 23 held by the base insulator 21. As shown in FIGS. The base insulator 21 has first and second mounting surfaces 27a and 27b that are parallel to each other in the uniaxial direction and adjacent to the pair of side surfaces 25, and a third mounting surface 27a and 27b on one end side in the uniaxial direction.
7c. A plurality of contacts 23 are held in this base insulator 21 in one axis direction. The contact 23 has a pair of terminal portions 23a extending outward from the third mounting surface 27C. Terminal section 23
The uniaxial outer side of a extends parallel to the first and second mounting surfaces 27a and 27b, respectively. The contacts 23 are arranged at equal pitches in a direction perpendicular to the uniaxial direction of the base insulator 21 .

Further, the contact 23 has a holding portion 23b held by the base insulator 21 at an intermediate portion in the uniaxial direction. The holding portion 23b is held by press-fitting both sides parallel to the uniaxial direction into the side walls of an opening 29 formed on the other side of the base insulator 21. Opening 2
A large opening 9 is formed into which the slide insulator 31 and flexible printed circuit board 33 can be inserted and removed together. In this opening 29, from the holding part 23b of the contact 23 toward the other side, that is, the insertion side of the slide insulator 31, there is a receiving piece 23c and a contact piece 2.
3d are spaced apart from each other and extend in the uniaxial direction. A contact portion 23e that protrudes toward the receiving piece 23c is formed at the tip of the contact piece 23d.

Further, the slide insulator 31 has an insertion opening 31a into which the flexible printed circuit board 33 can be inserted uniaxially without any insertion force, and a presser piece 31b extending uniaxially from one side of the insertion opening 31a. Presser piece 31
In b, the receiver is inserted between the piece 23c and the contact piece 23d. When the holding piece 31b is inserted into the opening 29, the flexible printed circuit board 33 is pressed in the thickness direction to bring the conductor portion 33a of the flexible printed circuit board 33 into contact with the contact portion 23e of the contact 23. ing.

Therefore, the connector shown in FIG. 1 is of a bottom contact type that contacts the conductor portion 33a on the bottom surface of the flexible printed circuit board 33.

Further, on the paired side surfaces 25 of the base insulator 21,
As shown in FIG. 5, grooves 35 are formed in each. Fittings 41 are attached to these grooves 35, as also shown in FIG. The fixture 41 is made, for example, by punching out a metal plate and then bending it. The fixture 41 is the first. second and third mounting surfaces 27a,
27b.

27c on one side of the mounting target board 39 such as a printed circuit board, the terminal portion 23a and the mounting target board 3
Protect the connection with 9. Furthermore, the fixture 41 serves as a first engagement device for preventing the slide insulator 31, which will be described later, from falling off the base insulator 21. To attach the fixture 41 to the groove 35, press the press-fit groove 3 formed near the bottom of the groove 35.
It can be firmly attached by press-fitting into 5a.

On the other hand, on one side of the slide insulator 31, a pair of arms 43 extends from both ends. Locking protrusions 43a are formed at the distal ends of the arms 43 so as to face each other with respect to the arms 43. Here, the arm 43 and the locking protrusion 43a
together constitute a second engagement device. These arms 43 have flexibility.

The fixture 41 also includes a first fixing piece 44a, a second fixing piece 44b1, and a third fixing piece 44c. 1st
The second fixing pieces 44a and 44b correspond to the first and second mounting surfaces 27a and 27b of the base insulator 21, respectively.

That is, the first and second fixing pieces 44a, 44b extend on the same plane as the first and second mounting surfaces 27a, 27b. The third fixing piece 44C extends on the same plane as the third mounting surface 27c. First fixed piece 44a, second fixed piece 44
b and the third fixing piece 44C are portions formed by being bent at right angles to one side from the flat plate surface of the fixture 41.

Furthermore, the fixture 41 has the above-mentioned first engagement device. This first engagement device is the slide insulator 3
1 to the second engagement device.

That is, the tenth engagement device includes a punched-out protrusion 45 formed by punching in the middle portion of the fixture 41, and an engaging claw formed at the end opposite to the third fixing piece 44c. 47. The engaging claw portion 47 is a portion that is bent to face the flat plate surface of the fixture 41.

The second engagement device of the slide insulator 31 cooperates with the first engagement device of the fixture 41 to prevent the slide insulator 31 from separating from the base insulator 21 .

Next, the flexible printed circuit board 33 is attached to the contact 23.
The operation of contacting the contact portion 23e will be explained. In this connector, the second mounting surface 27b faces the mounting target board 39. The slide insulator 31 can be moved back and forth in a uniaxial direction with respect to the base insulator 21. At this time, the locking protrusion 43a of the arm 43
It elastically rides over the ejection protrusion 45 and is positioned in front and behind it. Further, when the slide insulator 31 is pulled out from the base insulator 21, the locking protrusion 43a of the arm 43 engages with the engagement claw portion 47 of the attachment tool 41 to prevent the slide insulator 31 from coming off. In this way, the slide insulator 31 can be positioned in two positions: the position where it is pulled out in front of the base insulator 21 (see FIG. 7), and the position where it is pushed in (see FIG. 1). When the slide insulator 31 is pulled out in front of the base insulator 21, the opposing distance between the presser piece 31b located in the opening 29 and the contact piece 23d increases, and the flexible printed circuit board 33 can be inserted between them with zero insertion force.

Further, when the slide insulator 31 is pushed into the base insulator 21, the opposing interval between the presser piece 31b and the contact portion 23e is sandwiched, and the flexible printed circuit board 33 inserted between the two is pressed into contact with the contact portion 23e. In this way, the conductor portion 33g of the flexible printed circuit board 33
It can be used as a bottom contact type in which the contact portion 23e is brought into contact with the contact portion 23e.

Here, the conductor portion 33a of the flexible printed circuit board 33
In order to contact the contact portion 23e with the upper surface as the upper surface, the connector is used by inverting it. That is, as shown in FIG. 8, the first mounting surface 27a is opposed to the mounting target board 39. In this way, it can also be used as a top contact type connector in which the contact portion 23e contacts the flexible printed circuit board 33 with the conductor portion 33a directed toward the top surface.

The connector with the above configuration has the first and second fixing pieces 44a of the fixture 41 on either the bottom side or the top side.
The terminal portion 23a of the 44 bs contact 23 is located and can be connected by soldering onto the mounting target board 39.

Furthermore, by changing the contacts 23, this connector can be used as a vertically installed connector as shown in FIGS. 9 to 11. That is, in the vertical installation type connector, the terminal portion 23m of the contact 23 extends along the third mounting surface 27c, and the terminal portion 23m of the contact 23 extends along the first and second mounting surface 27a.
, 27b, at least one mounting surface 27g, 27b
It extends outward from. This contact 23 only needs to be formed with at least one terminal portion 23a.

According to such a vertically installed connector, the mounting target board 3
9 with the third mounting surface 27c facing the terminal portion 23.
a can be grounded to the mounting target board 39.

Furthermore, since the third fixing piece 44c can also be grounded to the mounting target board 39, the connecting portion between the terminal portion 23g and the mounting target board 39 can be protected.

[Effects of the Invention] As explained above using the embodiments, according to the connector of the present invention, by reversing one connector, it is possible to support both the bottom contact type and the top contact type, and only the contacts can be changed. Therefore, it can also be used as a vertically installed connector.

Furthermore, since the slide insulator is held by the fixture instead of the base insulator, the length of the base insulator in the pitch direction can be reduced, making it possible to save space.

Furthermore, since only one contact portion is required, a connector with a reduced mounting height can be obtained.
