Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a so-called zero insertion / removal force connector which can be inserted / removed with a very weak force, and particularly to a connector suitable for a multi-connector.

[0002]

[Prior Art]

 Various zero insertion / removal force connectors have been proposed in the past, but the structure was complicated and it was necessary to provide a reset mechanism such as a plunger.

[0003]

[Means for Solving the Problems]

 According to this invention, the contact piece is erected on one surface of the base body, and the rotary piece is held so as to be rotatable about an axis substantially parallel to the one surface of the base body. The side is adapted to engage with the contact piece by its rotation, and the holding part is fixedly provided to the base body, and the mating connector can be removably attached to the holding part. With the mating connector attached to the holding part, its contact is located close to the other side of the contact piece, and a drive unit having a drive unit engaged with the rotating piece is provided. By the operation, the rotating piece is rotated by the drive part so that the contact piece can be pressed into contact with the contact of the mating connector attached to the holding part.

【Example】

 FIG. 1 is an exploded view of the embodiment of the present invention, omitting a part thereof, FIG. 2A is a sectional view thereof, and FIG. 2B is a part of a left side surface thereof. In this example, the present invention is applied to a multi-connector, in which a thick plate substrate 11 made of an insulating material has a rectangular shape, and a plurality of contact pieces 12 are arranged in a line on one surface 11a of the substrate 11 to stand upright. One end (lower end in the figure) of the contact piece 12 is projected as a terminal 13 from the multiple surfaces of the base 11. Further, another contact piece 14 is provided in an array on the base 11 so as to face the array of the contact pieces 12, and one end of the contact piece 14 is also projected from the base 11 as a terminal 15.

A rotating piece 17 is provided on the base 11 so as to be rotatable about an axis 16 substantially parallel to the arrangement direction of the surface 11 a and the contact piece 12. The end of the rotating piece 17 is adapted to engage with the contact piece 12 by the rotation thereof. In this example, two rotating pieces 17 are provided corresponding to both ends of the base body 11, and a drive bar 18 is connected between the ends of both rotating pieces 17 opposite to the base body 11. It is substantially parallel to the arrangement direction of the contact pieces 12, and is close to or in contact with the contact pieces 12 from the side opposite to the contact pieces 14. A shaft 19 is fixed to an intermediate portion of both turning pieces 17 at a position of the shaft center 16.

Similarly, a shaft 20 parallel to the shaft 19 is provided so that the contact pieces 12 and 14 are arranged between the shafts 19 and 20, and rotating pieces 21 are fixed to both ends of the shaft 20, A drive bar 22 is fixed to one end of the rotating piece 21, and the drive bar 22 is in contact with or close to the intermediate portion of the contact piece 14 and the opposite side of the contact piece 12. A holding portion 23 is fixedly provided on the contact pieces 12, 14 side of the base body 11. The mating connector 24 can be removably attached to the holding portion 23, and when the mating connector 24 is attached to the holding portion 23, the contacts 25 and 26 thereof are located between the contact pieces 12 and 14. The mating connector 24 is positioned so as to closely face the end of the connector. In this example, the holding portion 23 has a flat rectangular tube shape, and the open end at one end thereof faces the surface 11 a of the base body 11, and the contact pieces 12, 14 and the rotating pieces 17, 21 are provided in the holding portion 23. The end is located.

In this example, when the multi-connector 24 at one end of the double-sided wiring board 28 is used as the mating connector 24, the multi-contacts 25 and 26 are formed as patterns on both sides of the end of the wiring board 28. There is. The double-sided wiring board 28 is housed and held at an intermediate position in the case 29, and electronic components 31 are mounted on both surfaces of the wiring board 28. One end of the case 29 and the multi-connector 24 side are open surfaces, and the end of the case 29 on the open surface side can be loosely inserted into the holding portion 23.

In order to determine the insertion position of the case 29 in this inserted state, a step portion 32 is formed on the inner surface of the holding portion 23, and the end surface of the case 29 abuts against the step portion 32. In this state, the multi-connector 24 is located between the free ends of the contact pieces 12, 14. When the driving body 33 is operated, the driving portion 34 of the driving body 33 turns the turning pieces 17 and 21. For this reason, the driving body 33 is movably provided substantially vertically to the surface 11a of the base 11, and the drive portion 34 is mounted at a right angle to the end portion of the base 11 side, and the drive portion 34 has a cylindrical shape. It is located between the other ends of the rotating pieces 17 and 21. The other end sides of the rotating pieces 17, 21 are closer to each other as they approach the tip. In this example, this connector is attached to the casing 35 of the electronic device, the holding portion 23 projects outside from the opening 36 of the casing 35, and is fixed to the casing 35. The driving body 33 also holds the casing 35. It projects to the outside through the hole. The shafts 19 and 20 are rotatably held by the box 35.

When the case 29, that is, the mating connector 24 is attached to the holding portion 23, the state shown in FIG. The mating connector 24 can be inserted by force. When the driving body 33 is pushed in in this state, the drive portion 34 opens the gaps between the ends of the rotating pieces 17, 21 as shown in FIG. 2C, and the rotating pieces 17, 21 rotate in opposite directions. The drive bars 18 and 22 at one end press the contact pieces 12 and 14 against the contacts 25 and 26, respectively. For holding and releasing this state, for example, the means used for the push button switch can be used. For example, a pin (not shown) is projected on the side surface of the driving body 33, and the pin engages with the heart groove of the lock portion 38 fixed to the casing 35. The state of FIG. 2C is retained by engaging with the recess of the groove, and the state of FIG. 2C is maintained. When the driver 33 is slightly pushed again, the state of FIG. 2C is released.

After releasing the lock and pulling out the driving body 33 and then removing the case 29 from the holding portion 23, the contacts 25 and 26 can be pulled out with a weak force without coming into contact with the contact pieces 12 and 14. In the above description, as shown by the alternate long and short dash line in FIGS. 2A and 2C, the rotating pieces 17 and 21 may be rotated by rotating the short rod-shaped drive portion 39. The holding portion 23 may not be cylindrical and may guide only the both side portions of the case 29. The contact pieces 12, 14 may be round bar-shaped ones instead of plate-shaped ones. The mating connector 24 may be held by a simple insulating block instead of the case 29. Further, one of the contact pieces 12, 14 and the one related thereto may be omitted. Further, the multi-connector does not have to be used.

[0011]

[Effect of the device]

 As described above, according to the present invention, when the mating connector 24 is inserted, since the contact is not in contact with the contact piece 12 (or 14), it can be inserted with an extremely weak force, and the drive unit can be externally connected. The contact piece is pressed against the contact by rotating the rotating piece 17 (or 21) by the operation, so that a good contact state can be achieved with a comparatively weak force. Even when the mating connector is pulled out, it can be pulled out with a weak force by pulling it while the contact piece is not in contact with the contact.
