Description

[Detailed Description of the Invention] [Technical Field of the Invention] The present invention relates to a mechanism for facilitating the insertion and removal of a connector with a large number of pins, such as a connector provided on the back panel of an electronic computer.

[Technical background of the invention and its problems]

In the past, connecting and disconnecting connectors to computer back panel pins was done manually, but
Due to the increase in the number of back panel pins associated with high-density packaging, the force required to insert and remove connectors has increased, making it difficult to insert and remove connectors using only human power. For this reason, ejector mechanisms that apply the principle of "lever" and can insert and remove connectors with a small amount of force have come into use, but as the number of pins increases,
This ejector mechanism not only has the drawback of being large and complicated, but also has the drawback of being a major constraint on miniaturization of the device. Another disadvantage is that this ejector mechanism limits the number of cables and spacers that come out from the printed circuit board to which the connector is attached. Fig. 4 shows a conventional example related to the above, in which 1 is a back panel of a computer, 2 is a plug type connector on the back panel side, and 3 is a back panel of a computer.
4 is a jack-type connector inserted into and connected to the connecting pin 3 provided on the printed board; 5 is an ejector mechanism for inserting or removing the connector 4 from the connector 2; 6 is a guide fitting of this ejector mechanism.

[Purpose of invention]

SUMMARY OF THE INVENTION In view of the above, an object of the present invention is to provide a connector insertion/removal mechanism which can eliminate the above-mentioned drawbacks when a jack-type connector is inserted into/removed from a back panel pin of an electronic computer.

[Summary of the idea]

In this invention, when inserting and removing a connector, a small diameter tap and a large diameter nut are formed so as to face each other on the guide fittings connected to both connectors forming a pair. By screwing in a threaded rod having both sides with different diameters that are connected at one end, it is possible to easily insert and remove the rod without increasing the size.

[Example of idea]

Figure 1 is a side view showing one embodiment of the present invention;
3 and 3 are side views of the functional section for explaining the insertion/extraction operation. In these figures, 1, 2, and 3 are the same as in FIG. 4. Reference numeral 15 denotes an insertion/extraction guide fitting A connected to the plug type connector 2 via the back panel 1, and reference numeral 16 denotes an insertion/extraction guide fitting B provided on the side opposite to the jack type connector 14 of the printed board. Further, 17 is a small diameter tightening tap S provided on the metal fitting A15, and 18 is a large diameter tightening nut L provided on the metal fitting B16. These taps 1
7 and nut 18 are coaxially arranged to face each other when both connectors 2 and 14 are connected. 1
Reference numeral 9 designates a double threaded rod in which a small diameter threaded rod 19a and a large diameter threaded rod 19b are coaxially connected at one end, and 20 represents an engagement portion with a driver serving as a screw driving means. Further, reference numeral 21 denotes a flange provided at the coupling portion to assist when the jaws of the large diameter threaded rod 19b cannot obtain sufficient engagement with the end surface 18a of the tightening nut L when the small diameter threaded rod 19a is used. It is.

Next, the operation and operation will be explained with reference to FIGS. 1 to 3. When inserting a connector into the back panel, insert the connecting pin 3 slightly into the connector 14 before inserting it, and then insert the small diameter threaded rod 19a.
pass through the screw hole of the large diameter tightening nut L18 and screw it into the tightening tap 17. As the flange 21 surface presses the end surface 18a of the tightening nut 18, the connector 14 is pushed into the connecting pin 3 via the insertion/extraction guide fitting B16, and the connector 14 is inserted. After completing this operation, both threaded rods 19 are unscrewed and set aside. Next, when removing the connector 14, the large diameter threaded rod 19b is screwed into the tightening nut L18. As screwing progresses, the tip of the large diameter threaded rod 19b reaches the front surface 17a of the tightening tap S17, and as the screw is further screwed in, the insertion/extraction guide fitting A15 and the insertion/extraction guide B16 are separated, allowing the connector 14 to be removed.

In the above, screwing was performed using a screwdriver through the screwdriver engagement part 20, but the shape of the flange 21 was changed (of course, the surface 21a remained) to form an engagement part that could be pinched and turned by hand. Alternatively, an engaging portion corresponding to the driving means can be formed by screwing in a tool such as a spanner.

[Effect of idea]

The present invention is as described above.)
Connectors with a large number of pins can be easily inserted and removed without requiring much force or space. ) Since one screw has two diameters, large and small, at both ends, insertion and removal can be reliably performed with the same tightening operation.
) No need for an exaggerated mechanism such as an ejector mechanism. Effects such as this can be obtained.
