Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates generally to electrical connectors, and more particularly to an electrical connector device having a header connector for receiving an IC pack and means for ejecting the IC pack from the header connector.

[0002]

[Prior Art]

 Header connectors are used with IC packs and memory cards and are provided with various attachments, such as means for facilitating ejection of the IC pack for replacement. Header connectors are used to interconnect the semiconductor circuits of an IC pack to external circuits such as the main electronic unit. The IC pack is inserted into the header connector and removed from it as needed. The pulling force for taking out the IC pack, that is, the force applied between each pin arranged on the header connector and each terminal of the IC pack, requires close fitting to obtain good electrical contact. Being relatively strong, it is relatively strong. When the IC pack is taken out by hand, it is often taken out in an oblique direction, and each terminal or contact may be damaged.

[0003]

[Problems to be solved by the device]

 Therefore, various ejecting mechanisms are incorporated in various electrical connector devices in order to make it easier to eject the IC pack from the header connector. One of the problems with using the eject mechanism is to increase the overall size of the device body. In various applications, it is desirable to make the entire connector device as thin as possible, for example, to stack a plurality of header connectors. When various attachments such as an eject mechanism are arranged outside the header connector shape, particularly outside the thickness of the header connector, it is difficult to make a thin structure. It is difficult to reduce the thickness of the entire header, and therefore the entire connector device becomes large by the amount of the attachment.

The present invention is an ejecting means for ejecting an IC pack from a header connector, which is an improved eject that is practically limited in thickness within the thickness of the IC pack, or at least within the thickness of the header connector. It is an attempt to overcome these problems by providing means within the connector arrangement.

Therefore, an object of the present invention is to provide an electric connector device for an IC pack having a new and improved eject mechanism for ejecting the IC pack from the header connector.

 Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings. Referring to FIG. 1 of the accompanying drawings, a connector device 10 according to the present invention comprises a header connector 12, a housing means 14, an ejecting means 16, an actuator means 18 and an operating means 20.

Referring to FIG. 2 in conjunction with FIG. 1, header connector 12 includes an insulative header housing 22 integrally molded with an insulative material such as plastic. This header housing mounts multiple terminals in high density. The terminals are inserted into the pin part 24 inserted into the contact socket of the IC pack and the hole of the printed circuit board, or 28 in FIG. A solder tail portion 26 is surface mounted to the circuit traces on the printed circuit board as shown. The header housing 22 has a pair of arms 30 provided with latch protrusions 32 protruding outward. The housing 22 also defines an internal receptacle 34 for receiving an IC pack that terminates in the pin portion 24 of the terminal. Furthermore, the header housing also has a slot 36 in which the ejecting means 16 (FIG. 1) can be moved back and forth. Although not shown, the IC pack has a normal flat shape and has a socket for receiving the pin portion 24 of the terminal at one edge. The thickness of the IC pack is less than or equal to the thickness of the internal receptacle 34.

As is apparent from FIG. 1, the housing means 14 is generally formed with an inverted U-shaped cross section and includes a top wall portion 38, opposing side wall portions 40a and 40b, and an inner wall portion. 42 and 44 are provided. The housing means 14 is attached to the top surface of the printed circuit board by suitable screws 46. The outer wall 40a and the inner wall 42 extend longer than the upper wall 38 and are provided with notches 48. The notch is engaged by the latch projection 32 of the header connector 12 during assembly of the connector device. The outer wall 40b and the inner wall 44 define a channel 50 in which the actuating means 20 in the form of a push rod is arranged for reciprocating movement.

The ejecting means 16 is formed of a generally U-shaped member including a pair of legs 52. The leg 52 projects into the slot 36 of the header housing 22. The thickness of the U-shaped eject member is substantially within the thickness of the IC pack put in the receptacle 34, and is actually thinner than the thickness of the header housing 22.

The actuator means 18 is in the form of a lever 54 having opposite ends 54a and 54b. The lever 54 is pivotally attached to the header housing 22 by a pivot bolt 58 which extends freely through a flange 56 that projects into one of the slots 36 and through a hole 60 in the flange and a hole 62 in the header connector. The actuator lever 54 has a thickness similar to that of the U-shaped eject member 16, and the lever is arranged within the thickness of the IC pack. At least the thickness of the lever is equal to or less than the thickness of the header connector 12. The same applies to the thickness of the operation push rod 20.

FIG. 4 shows the components of the connector device 10 described above with reference to FIG. 1 in an assembled state. It can be seen that the latching protrusion 32 on the arm 30 of the header housing 22 snaps into the notch 48 of the housing means 14. The leg 52 of the U-shaped eject means 16 is inserted into the slot 36 of the header connector 12, and the actuator lever 18 is pivotally attached to the header connector. As is apparent from this figure, the operating push rod 20 has an enlarged portion 64 which is encased in the channel 50 of the housing 14 to stabilize the movement of the push rod. Further, the enlarged portion has a socket portion 66 for engaging the rounded end 54b of the actuator lever 18 when the end 54a engages the U-shaped eject member 16. ing.

Referring to FIG. 4, the operation of the embodiment of the present invention shown in FIGS. 1 to 4 will be described. In order to take out the IC pack from the header connector 12, a user exposes the operation push rod 20. Push end 68 as indicated by arrow A. The push rod pivotally rotates the actuator lever 18 in the direction of arrow B. By engaging the end 54a of the lever and the U-shaped eject member 16, the eject member moves in the direction of arrow C by the pivotal rotation of the lever, and the far end of the leg 52 engages the IC pack. , The IC pack is released from the header connector, and the connection with the pin portion 24 of the terminal is disconnected.

5 and 6 show a second embodiment of the present invention including a header connector 70. This header connector 70 is very similar to the header connector 12 shown in FIGS. 1 to 4, but has a recessed area 72 in its upper part for receiving a plate-shaped operating member 74. The operating plate 74 serves the same purpose as the push rod 20 shown in FIGS. This operation plate has a pair of extended arms 76, and a flange 76a is provided at the distal end thereof.

In the embodiment shown in FIGS. 5 and 6, the actuator means is in the form of a pair of levers 78 and 80, which are suitably pivotally attached to the printed circuit board by a common pivot 82 in the middle of their ends. To be done. Lever 78 has opposite ends 78a and 78b and lever 80 has opposite ends 80a and 80b. Each of the ends 78a and 80a of the levers 78 and 80 is in the form of a post portion for engagement with a flange 76a of the actuation plate 74, as shown in FIG. Opposite ends 78b and 80b of actuating levers 78 and 80, respectively, engage a pair of eject rods 82, which in turn engage both ends of an IC pack inserted into header connector 70.

As is apparent from FIG. 6, a pair of header connectors 70 are arranged in a stacked array, and the tail portion of one header connector terminal is longer than the other for surface mounting on a printed circuit board. There is. Therefore, a pair of eject rods 82 is provided at each opposite end of each header connector so that two IC packs can be ejected simultaneously from the header connector. For this reason, the ends 78b and 80b of the actuator levers 78 and 80 are also formed by the post-like portions of the distal ends of these levers for engaging the eject rods 82 at each end of the header connector. ..

When operating the connector arrangement of FIGS. 5 and 6, the operating plate 74 is moved in the direction of arrow D to engage the flange 76a with the ends 78a and 80a of the actuator levers 78 and 80, respectively. This causes the ends of these levers to move in the direction of arrow E. Thus, the opposite ends 78b and 80b of the levers are pivoted in the direction of arrow F, like scissors. As a result, the eject rod 82 is moved in the direction of the arrow F and engages with both ends of the two IC packs to eject these packs from the stacked header connector.

7 and 8 show the eject and actuator means of a third embodiment of the present invention. More specifically, each of the pair of stacked header connectors 70 mounts a pair of eject rods 82 for reciprocal movement, as described with respect to FIGS. 5 and 6. Unlike the scissor levers in FIGS. 5 and 6, in FIGS. 7 and 8, a pair of levers 84 and 86 are pivotally attached to the printed board at intermediate ends 88 and 90, respectively. The levers 84 and 86 have adjacent proximal ends 84a and 86a and spaced distal ends 84b and 86b, respectively. The ends 84b and 86b of these levers are arranged to engage one of the eject rods 82, respectively. Although not shown, suitable operating means, such as the push rod actuating means 20 shown in the embodiment of FIGS. 1-4, may be used to effectively engage the ends 84a and 86a of the lever as indicated by arrow G. To combine.

In operating the connector device shown in FIGS. 7 and 8, when an operating means such as a push rod is moved in the direction of arrow G with respect to the ends 84a and 86a of the lever, the opposite ends 84b and 86b of the lever are moved. Are pivoted about their respective pivot points 88 and 90 in the direction of arrow H to engage eject rod 82 which in turn engages both ends of the IC pack to attach the pack to header connector 70. To release from. In this embodiment, the two header connectors are arranged in a stacked array so that two IC packs are ejected from both header connectors at the same time.
