Abstract:
A multi-I/O-port-41-channel connector includes first and second connectors, in which associated connecting pins and plugholes as well as a fastening device is available to thereby prevent any possible faulty connection and provide a convenient operation for enhanced fastening or detaching of the connectors.

Description:
BACKGROUND OF THE INVENTION 
     1. Field of the Invention 
     The present invention relates to a multi-I/O-port-41-channel connector, which forms a buckle device and cooperative connecting pins and holes through paired male/female couplings for preventing faulty connection and providing easy operation for fastening or detaching of the connector. 
     2. The Prior Arts 
     A generic connector is formed by jointing a male coupling with a female coupling together for transmitting signals or data between two electronic devices, in which there is a most important connecting and fixing structure of male/female coupling in addition to a lead-wire connecting structure. A major of such a connecting and fixing structure of male/female coupling is fast connection/disconnection and connection strength resisting undesired separation. 
     SUMMARY OF THE INVENTION 
     It seems to be a usual way so far to joint and fix connectors by locking with bolts or fastening devices, in which the bolt is strong enough to build a reliable connection but weak in operability, while the fastening device is good for operation but weak in strength and it is particularly unsuitable to a 41-channel connector, after all, they are defective in one way or another. 
     Therefore, a primary object of the present invention is to provide an improved structure of multi-I/O-port-41-channel connector for eliminating foregoing defects. 
     In order to realize the above object, an improved structure of multi-I/O-port-41-channel connector of the present invention is comprised of a first connector and a second connector. 
     The first connector has a front end extended forwards to form a female coupling, in which a central portion of a front edge at its top end is dug away to form a mortise, and a plurality of plugholes is provided with respective lead wires for signal transmission. The second connector also has a front end extended forwards to form a male coupling, in which a plurality of lead wires for signal transmission is provided and extended outwardly to form a plurality of connecting pins. The plugholes and the connecting pins arranged in respective couplings are zigzag correspondent. When the first connector is to be butt-jointed with the second connector, a tenon of an extension arm in the second connector is engaged with the mortise in the first connector through a stroke of depression onto a pushbutton of the extension arm to hence joint or detach the connectors. 
     The merits of the multi-I/O-port-41-channel connector of the present invention may be summarized as the following: 
     (1) It is possible to prevent faulty connection by means of a fastening device and the corresponding plugholes and connecting pins. 
     (2) The fastening device is particularly good in fastening and detaching operability as well as connection quality. 
     (3) To simplify the fabrication process and accordingly lower the fabrication cost is possible.

     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT 
     An embodiment of a multi-I/O-port-41-channel connector constructed in accordance with the present invention shown in the drawings, including FIGS. 1-4 comprises a first connector  1  and a second connector  2 . 
     The first connector  1  has a front end extending forwards to form a female coupling  12 , in which a central portion of a front edge at its top end is dug away to form a mortise  11 , and a plurality of plugholes  14  is provided with respective lead wires for signal transmission. The second connector  2  has a front end extending forwards to form a male coupling  20 , in which a plurality of lead wires for signal transmission is provided and extending outwardly to form a plurality of connecting pins  24 . 
     The outer fringe of the female coupling  12  in the first connector  1  and the corresponding inner fringe in the mouth of the male coupling  20  of the second connector  2  are designed to form a tight sleeve-joint mechanism. 
     At the top end of the male coupling  20  of the second connector  2 , a recess extends forwards to form a receptacle  21  and a through hole  22  for accommodating a fastening device  23 . In the fastening device  23 , a fixing portion  25  at one end is fixed in the receptacle  21  and extended outwardly to reach the inner space of the male coupling  20  and form a resilient extension arm  26 . A pushbutton  27  is fixedly disposed on the top end of the extension arm  26 , and the fore end of the extension arm  26  is located right under the through hole  22  and is extended upwardly to form a wedge-style tenon  28  with an outward slope. When the pushbutton  27  is depressed, the extension arm  26  is supposed to bend downwardly to sink the tenon  28  under the through hole  22 . 
     When the first connector  1  is butt-jointed with the second connector  2 , the tenon  28  is engaged with the mortise  11 . For more details, reference is made to FIGS. 3 and 4. When jointing the first and the second connector  1 ,  2  together, the tenon  28  of the second connector  2  is at the very beginning forced down by an upper transom of the mortise  11  of the first connector  1  to lower down the front end of the extension arm  26  of the fastening device  23  accordingly until the tenon  28  enters the mortise  11  to have these two connectors jointed. 
     For detaching the connectors  1 ,  2  from each other, the pushbutton  27  of the fastening device  23  is depressed and the front end of the extension arm  26  is bent downwardly to descend the tenon  28  to escape from the mortise  11 , thus the connectors are detached accordingly. 
     Moreover, a plurality of spring leaves  29  is fixedly disposed on the inner wall of the male coupling  20  for tightening the connection of the couplings  12 ,  20 . 
     The plugholes  14  and the connecting pins  24  are aligned in respective arrays with corresponding zigzag rows on one-hole-to-one-pin basis (as shown in FIG.  5  and  6 ). In this case, both the amount of the plughole  14  and the connecting pin  24  are  41 . 
     Finally, one point to be mentioned is a function for preventing faulty connection. That is, any incorrect connection of the connectors  1 ,  2  is prohibited in order not to damage the plugholes  14  or the connecting pins  24  according to the present invention. 
     In the above described, at least one preferred embodiment has been described in detail with reference to the drawings annexed, and it is apparent that numerous changes or modifications may be made without departing from the true spirit and scope thereof, as set forth in the claims below.
