Description

The present invention relates to a connector with an adsorption member.

A top-type connector into which a male connector such as a socket is fitted from above includes a housing having a concave opening into which the socket is inserted, and a plurality of contacts fitted into the opening. In addition, in a surface-mounted connector or the like, contacts exposed on the bottom or lower side of the housing are soldered to a plurality of electrodes formed on the surface of the motherboard.

In order to automatically mount the connector on the motherboard, the connector is sold on the market while being housed in, for example, an embossed carrier tape. The embossed carrier tape includes a band-shaped carrier tape main body that is connected to a bathtub-shaped case portion that accommodates connectors one by one, and a band-shaped protective tape that covers the case portion in which the connectors are accommodated. The protective tape is releasably bonded to the carrier tape body.

In the automatic connector mounting process, the automatic mounting machine sequentially feeds the embossed carrier tape while peeling off the protective sheet, and the suction device of the automatic mounting machine suctions the suction surface of the connector to remove the connector from the case and remove the solder cream. A plurality of contacts of the connector are aligned and placed on the plurality of coated electrodes on the surface of the motherboard. In this state, the motherboard is sent to a high-temperature bath, and the contacts and electrodes are soldered by reflowing the solder, and the connector is mounted on the motherboard surface.

In the above automatic mounting, it is necessary to provide a suction surface on the connector to which the suction device suctions. In particular, in the case of a top type connector, since the opening into which a socket or the like is fitted opens upwards of the connector, a suction cap having a suction surface is attached to the opening of the housing. For example, Patent Document 1 describes an example of such a connector and suction cap. Furthermore, Patent Documents 2 and 3 describe examples of connectors and adsorption tapes.

In this embodiment, in order to lock the fitted state between the connector 1 and the socket 50, the connector 1 is provided with a lock protrusion 21, and the socket 50 has a lock claw 55 at the tip of the suction member rotating member 54. A locking operation is then performed at the second opening 20 of the connector. Based on this configuration, in this embodiment, the suction member 30 is attached to the mounting shaft 19 provided on the outer front wall 17 of the connector 1, to provide a suction surface during automatic mounting of the connector, and to provide a suction surface when inserting the socket after mounting. The suction member rotating member 54 of the socket performs a locking operation and also performs an operation of pushing down the suction member 30. Thereby, the space of the second opening 20 of the connector is effectively utilized.

[Second embodiment and modified example of socket]
FIG. 9 is a perspective view showing an example of a socket in the second embodiment. In the second embodiment, unlike FIGS. 2(1) and 3, the lock convex portion 21 and the lock slope portion 22 are not provided in the second opening 20 of the connector 1. Accordingly, as shown in FIG. 9, the suction member rotating member 54 of the socket 50 does not have the lock claw 55 or the lock release piece 56.

That is, in the second embodiment, there is no function to lock the fitted state of the connector and the socket. However, when the socket 50 is inserted into the connector 1, the suction member rotation member 54 of the socket 50 is inserted by sliding on the second opening side of the inner front wall 16 of the connector 1. As a result, the suction member rotating member 54 of the socket and the socket housing 51 fit together so as to sandwich the inner front wall 16 of the connector, and the inner front wall 16 and the rear wall 12 of the connector sandwich the tip of the socket housing 51. to strengthen the mating strength.

Therefore, in the second embodiment as well, the space of the second opening 20 of the connector is effectively utilized.

[Rotational movement of the adsorption member of the connector and modification of the mounting shaft]
FIG. 10 is a diagram showing a rotational movement of the adsorption member of the connector and a modification of the attachment shaft. (1-1), (1-2), and (1-3) in FIG. 10 show the rotational operation of the adsorption member 30 in an example in which the mounting shaft 19 has a hexagonal cross section. (2) and (3) in FIG. 10 show modified examples of the mounting shaft. Both are cross-sectional views taken along the mounting shaft 19 of the housing 10 of the connector 1.

First, FIG. 10 (1-1), (1-2), and (1-3) will be explained. In this example, the mounting shaft 19 has a hexagonal cross section, and has a shape in which one pair of opposing corners of a regular quadrangle whose vertical plane coincides with the outer front wall 17 of the connector 1 is defined as a side 19A. On the other hand, the mounting member 32 of the suction member 30 has an L-shaped cross-sectional shape on the left side in the figure, and has a mounting slope 32A at the tip of the L-shape.

In the case of the mounting shaft 19 on the connector side and the mounting member 32 of the suction member 30 having such a shape, the operation of attaching the suction member 30 to the mounting shaft 19 and the operation of rotation around the mounting shaft 19 are as follows. Become. First, in FIG. 10 (1-1), in the mounting operation of the suction member 30 to the mounting shaft 19, when the mounting member 32 of the suction member 30 is pressed against the mounting shaft 19 from above, the mounting slope 32A of the mounting member 32 is The attachment member 32 is spread out while sliding on the side 19A of the attachment shaft 19, and then the L-shape of the attachment member 32 engages with the attachment shaft 19. In this state, the vertical surfaces of the mounting member 32 of the suction member 30 sandwich the vertical surface of the mounting shaft 19 from both sides, and the suction plate 31 maintains its horizontal state against a predetermined downward force.

Next, in FIG. 10 (1-2), the tip of the suction plate 31 is pushed down by the downward pressure of the suction member rotation member of the socket (not shown), and the inner surface of the attachment member 32 touches the side 19A of the attachment shaft 19. It is sandwiched from both sides. Furthermore, in FIG. 10 (1-3), the suction plate 31 of the suction member 30 is further pushed down and is housed in the second opening 20.

Due to the shape of the mounting shaft 19 and the shape of the mounting member 32 of the suction member 30 as described above, the mounting member of the suction member to the mounting shaft and the mounting shaft can be easily attached to the mounting shaft when the suction member is attached to the mounting shaft. Rotation of the suction member is inhibited, and rotation is allowed when the male connector is inserted.

FIG. 10(2) shows a first modification of the mounting shaft 19. The cross-sectional shape of this mounting shaft 19 is an octagon with four corners of a square cut off. Even with such an octagonal shape, the mounting operation and rotational operation of the suction member 30 similar to those shown in FIGS. 19(1-1) to (1-3) are possible due to one pair of opposing sides 19A.

FIG. 10(3) shows a second modification of the mounting shaft 19. The cross-sectional shape of this mounting shaft 19 is a vertically long ellipse. In the case of such a vertically elongated elliptical shape, due to the opposing curved surfaces in the major axis direction, the mounting member 32 of the suction member 30 to the mounting shaft 19 and the mounting shaft 19 can be easily attached to the mounting shaft with the suction member attached to the mounting shaft. Rotation of the suction member is suppressed, and when the male connector is inserted, the suction plate is strongly pressed down and rotation is enabled.

As described above, according to the present embodiment, since the suction member 30 is attached to the connector 1, the suction device of the automatic mounting machine suctions the suction surface of the suction member in the automatic mounting process and automatically mounts the connector. When the male connector is inserted into the connector 1 after mounting, the suction member 30 is accommodated in the second opening of the connector, so there is no need to remove the suction member after mounting.
