Description
., Mounting of Electric Connector BACKGROUND OF THE INVENTION
(Field of the Invention) The present invention generally relates to an electric connector for extemal electric connection and, more specifically, to a connector mounting for supporting the electric connector on a substrate such as, for example, a printedcircuit board.
(Description of the Prior Art) o To fix on a printed circuit board the electric connector used forexternal electric connection such as, for example, a DC jack or pin jack connector, one approach is generally employed to solder the electric connector to the printed circuit board.
This known mounting method has been found having a number of problems. During mounting of a printed circuit board on an electric appliance, it has been often experienced that the electric connector mounted on the printedcircuit undesirably contacts one or more component parts of the electric appliance, or that the printed circuit board having the electric connector mounted thereon may be inadvertently dropped onto a floor. In the event that as a result of the contact of the electric connector with the component parts ofthe electric appliance or the fall of the printed circuit board onto the floor, an external force acts on the electric connector, stresses are built up at and around portions of the printed circuit board where the electric connector is soldered.
The stresses so built up eventually lead to breakage of printed circuit conductors.
In view of the foregoing problem, it has hitherto been suggested to use a generally U-shaped plate-like supporter 10 as shown in Fig. 5 to protect the electric connector 1 from the external force. Specifically, the supporter 10 conencted at its opposite ends to the printed circuit board P by the use of screws B so as to overhang the electric connector 1 such that the supporter 10 can receive the external force to thereby prevent the electric <1>
connector 1 from being affected directly by the external force and, hence, to prevent the printed circuit conductors 8 from being broken.
The prior art connector mounting system discussed with reference to Fig. 5 requires the use of an extra component parts such as the supporter 10 to protect the electric connector from the external force to thereby protect theprinted circuit board on which such electric connector is mounted. The use of such an extra component parts results in reduction in available space on the printed circuit board and also in increase of a manufacturing cost.
SUMMARY OF THE INVENTION
0 The present invention has accordingly been devised to substantially elimin~te the above discussed problems and is intended to provide an improved connector mounting system effective to protect the substrate, on which the electric connector is mounted, from the external force without the available space being reduced and without the manufacturing cost being increased.
In order to accomplish the foregoing obiect, the present invention provides a connector mounting for supporting an electric connector for external electric connection, which comprises a substrate having generally elongated grooves defined therein so as to define a major substrate body and a mounting 20 body. The elongated grooves have respective ends spaced a distance from each other so as to define a connecting neck which connects the major substrate body and a mounting body integrally together, and electric circuit conductors formed on the major substrate body and the mounting body, respectively. A plurality of ~lexible jumper wires are used to connect the majorsubstrate body and the mounting body together at a location spaced from the connecting neck, said jumper wires having opposite ends electrically connected with the electric circuit conductors on the major substrate body and the mounting body, respectively, to thereby electrically connect the electric circuit conductors together.
<2>
The flexible property of the jumper wire is intended to mean a capability of the jumper wires undergoing elastic deformation or plastic deformation upon receipt of an external force.
According to the present invention, because of the provision of the 5 elongated grooves substantially separating the mounting body from the major substrate body and the capability of the jumper wires undergoing an elastic deformation while electrically connecting the electric circuit conductors on themajor substrate and mounting bodies together, the mounting body can displace relative to the major substrate body. Accordingly, the possibility can be advan-0 tageously avoided which the electric circuit conductors on the mounting bodymay be adversely affected by a relatively large shearing force induced at the solder connections where the connector and the mounting body are physically connected.
Moreover, it is possible to avQid the possibility that an adverse 5 effect which would be brought about by the external force acting on the mounting body of the substrate may be tr~n.~mitted tQ the major substrate body, to thereby minimi7e the possibility of breakage of the circuit between the electric circuit conductors.
In a pl~ell~d embodiment of the present invention, the mounting 20 - body has front and rear edges opposite to each other, said front edge forming a portion of one edge of the substrate, and the elongated grooves are cut inwardly from said one edge of the substrate so as to define the mounting body with said connecting neck positioned distant from the such one edge of the substrate. Preferably, the mounting body may of a generally rectangular 25 configuration having, in addition to the front and rear edges, side edges opposite to each other and lying generally perpendicular to any one of the frontand rear edges. In this case, the connecting neck is positioned adjacent the rear edge of the mounting body, and the elongated grooves are each cut completely across the thickness of the substrate and extend inwardly from such one edge <3>
of the substrate to a portion adjacent the connecting neck along a generally L-shaped line.
The elongated grooves are therefore positioned adjacent the opposite side edges of the mounting body, respectively. Also, the jumper wires 5 may straddle the elongated grooves to connect the major substrate body and the mounting body together.
With this mounting system, even though an external force is applied laterally to the connector, the mounting body is elastically displaced sidewise and the jumper wires follows the displacement of the mounting body 0 to absorb the external force and, therefore, it is prevented that the externalforce directly acts on the connecting portion between the connector and the mounting body or is directly transmitted to the major substrate body.

DETAILED DESCRIPTION OF THE EMBODIMENTS
A connector mounting system by which the electric connector is 5 fixedly molmted on a substrate, for example, a printed circuit board accordingto a preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. Referring particularly to Fig. 1, the printed circuit board indicated by P has a generally rectangular mounting portion 2 and the rem~ining portion or a major substrate body 4. The 10 mounting portion 2 is separated from the rem~ining portion 4 by means of a pair of generally L-shaped grooves 2-1 and 2-2 formed by cutting the printed circuit board P inwardly from one side edge thereof so as to leave an uncut region serving as a connecting neck 5 through which the mounting portion 2 remains integrated together with the rem~ining portion 4.
The mounting portion 4 so forrned has a front edge 20, a rear edge 21 opposite to the front edge 20, and side edges 22 and 23 lying generally perpendicular to any one of the front and rear edges 20 and 21 and is positioned adjacent the perimeter Pa of the printed circuit board P with the front edge 20 aligned with a front edge 30 of the printed circuit board P. The 20 connecting neck 5 cormecting the mounting portion 2 and the rem~ining portion4 integrally together is positioned adjacent the rear edge 21 opposite to the front edge 20 and, hence, remote from the front edge 30 of the printed circuit board P. Tl1e L-shaped grooves 2-1 and 2-2 are positioned adjacent the side edges 22 and 23, respectively, of the mounting portion 2, each extending 2s inwardly from the front edge 30 of the printed circuit board P and along the associated side edge 22 or 23 of the mounting portion 2 and then bent to extend along the rear edge 21 before it terminates adjacent the connecting neck 5.
The mounting and rem~ining portion 2 and 4 of the printed circuit board P have electric circuit conductors 8 printed on their undersurface in a 30 predetermined circuit pattern. The electric connector 1 for external electric <s>
connection such as, for example, a DC jack or pin jack cormector, is mounted on and soldered at H to the mounting portion 4 of the printed circuit board P.
As best shown in Fig. 2, the electric connector 1 has a plurality of, for example, two, terminal pins 15 extending downwardly from the bottom thereof, and 5 those tçrmin~l pins 15 are, after the electric connector 1 has been mounted onthe mounting portion 2 of the printed circuit board P with the terminal pins 15 inserted through terminal holes 16 defined in the mounting portion 2, soldered at H to appropriate circuit conductors 8.
As best shown in Fig. 3 in a sectional representation, the mounting o and rem~ining portions 2 and 4 are connected together by means of a plurality of, for example, two, pairs of jumper wires 6 str~ lling respective portions of the grooves 2-1 and 2-2 adjacent the side edges 22 and 23. Those jumper wires 6 are made of a material of a kind having both an electroconductivity and a sufficient flexibility, which material may conveniently employed in the form 5 of stainless steel. The flexibility possessed by the material for the jumper wires 6 is intended to mean a property having a capability of undergoing elastic deformation or plastic deformation. The jumper wires 6 employed in the practice of the present invention has a property capable of undergoing plastic deformation. The electric circuit conductors 8 formed on the mounting portion 20 2 and the electric circuit conductors formed on the rem~ining portion 4 are electrically connected with each other by means of the jumper wires 6, the jumper wires 6 of each pair being situated adjacent the respective side edge 22 or 23 with their opposite ends soldered at H to the associated electric circuit conductor 8 as clearly shown in Fig. 3. In this way, the mounting and remain-25 ing portions 2 and 4 of the printed circuit board P are connected together notonly through the connecting neck 5, but also through the jumper wires 6 positioned sidewise of the connector 1.
Referring now to Fig. 4, if an external force acting in a direction sidewise of the connector as shown by the arrows S acts on the connector 1 30 and is then transmitted to the mounting portion 2 of the printed circuit board P, <6>
the presence of the L-shaped grooves 2-1 and 2-1 substantially surrounding such mounting portion 2 and the flexibility of the iumper wires 6 allow the mounting portion 2 to displace sidewise in a direction conforming to the direction S with the connecting neck S yielded to twist, wherefore the 5 possibility can advantageously be avoided which the electric circuit conductors 8 on the mounting portion 3 may be adversely affected by a relatively large shearing force induced at the solder connections H where, as shown in Fig. 2, the connector 1 and the mounting portion 2 are physically connected.
Moreover, even though the mounting portion 2 is displaced o sidewise in the manner described above, the jumper wires 6 follows the displacement of the mounting portion 2 to undergo a corresponding elastic deformation and, therefore, neither the physical connection between the jumper wires 6 of one pair and the electric circuit conductors 8 on the mounting portion 2 nor the physical connection between the jumper wires 6 of the other pair and 15 the electric circuit conductors on the rem~ining portion 4 will adversely affected.
Thus, the external force so acting on the mounting portion 2 through the connector 1 is sufficiently absorbed by the L-shaped grooves 2-1 and 2-2 around the mounting portion 2 and the jumper wires 6 having a 20 sufficient flexibility as discussed above, so far from being undesirably trans-mitted to the rem~ining portion 4 of the printed circuit board P, and therefore the electric circuit conductors 8 are not adversely affected by the external force so applied.
As hereinbefore discussed, the present invention makes it possible 25 to dispense with the use of any extra component parts such as the supporter 10 required in the practice of the prior art mounting method shown in Fig. 5, no available space will be sacrificed and the product can therefore be manufac-tured at a reduced cost. In addition, since in the illustrated embodiment the only connecting neck 5 is employed as positioned adjacent the rear edge 21 of <7>
the mounting portion 2, the mounting portion 2 can swing and/or twist slightly to absorb the external force applied to the mounting portion 2.
Although the present invention has been fully described in connection with the preferred embodiment thereof with reference to the accompanying drawings which are used only for the purpose of illustration, those skilled in the art will readily conceive numerous changes and modifi-cations within the framework of obviousness upon the reading of the specification herein presented of the present invention. For example, in the foregoing description, the mounting and rem~ining portions 2 and 4 of the o printed circuit board P have been integrally connected together through the connecting neck S positioned adjacent the rear edge 21 of the mounting portion 2. However, the connecting neck may not be always positioned adjacent the rear edge 21 ofthe mounting portion 2, but may be positioned adjacent any one of the other edges of the mounting portion 2, for example, adjacent at least oneof the side edges 22 and 23 of the mounting portion 2.
Also, although the connector 1 has been shown as a DC jack or pin jack connector, the present invention can be equally applicable to an electric connector used to receive a heavy electric component part such as a plug of a switching adaptor (an AC-DC converter).
Accordingly, such changes and modifications are, unless they depart from the scope of the present invention as delivered from the claims annexed hereto, to be construed as included therein.

DETAILED DESCRIPTION OF THE EMBODIMENTS
A connector mounting system by which the electric connector is 5 fixedly molmted on a substrate, for example, a printed circuit board accordingto a preferred embodiment of the present invention will now be described in detail with reference to the accompanying drawings. Referring particularly to Fig. 1, the printed circuit board indicated by P has a generally rectangular mounting portion 2 and the rem~ining portion or a major substrate body 4. The 10 mounting portion 2 is separated from the rem~ining portion 4 by means of a pair of generally L-shaped grooves 2-1 and 2-2 formed by cutting the printed circuit board P inwardly from one side edge thereof so as to leave an uncut region serving as a connecting neck 5 through which the mounting portion 2 remains integrated together with the rem~ining portion 4.
The mounting portion 4 so forrned has a front edge 20, a rear edge 21 opposite to the front edge 20, and side edges 22 and 23 lying generally perpendicular to any one of the front and rear edges 20 and 21 and is positioned adjacent the perimeter Pa of the printed circuit board P with the front edge 20 aligned with a front edge 30 of the printed circuit board P. The 20 connecting neck 5 cormecting the mounting portion 2 and the rem~ining portion4 integrally together is positioned adjacent the rear edge 21 opposite to the front edge 20 and, hence, remote from the front edge 30 of the printed circuit board P. Tl1e L-shaped grooves 2-1 and 2-2 are positioned adjacent the side edges 22 and 23, respectively, of the mounting portion 2, each extending 2s inwardly from the front edge 30 of the printed circuit board P and along the associated side edge 22 or 23 of the mounting portion 2 and then bent to extend along the rear edge 21 before it terminates adjacent the connecting neck 5.
The mounting and rem~ining portion 2 and 4 of the printed circuit board P have electric circuit conductors 8 printed on their undersurface in a 30 predetermined circuit pattern. The electric connector 1 for external electric <s>
connection such as, for example, a DC jack or pin jack cormector, is mounted on and soldered at H to the mounting portion 4 of the printed circuit board P.
As best shown in Fig. 2, the electric connector 1 has a plurality of, for example, two, terminal pins 15 extending downwardly from the bottom thereof, and 5 those tçrmin~l pins 15 are, after the electric connector 1 has been mounted onthe mounting portion 2 of the printed circuit board P with the terminal pins 15 inserted through terminal holes 16 defined in the mounting portion 2, soldered at H to appropriate circuit conductors 8.
As best shown in Fig. 3 in a sectional representation, the mounting o and rem~ining portions 2 and 4 are connected together by means of a plurality of, for example, two, pairs of jumper wires 6 str~ lling respective portions of the grooves 2-1 and 2-2 adjacent the side edges 22 and 23. Those jumper wires 6 are made of a material of a kind having both an electroconductivity and a sufficient flexibility, which material may conveniently employed in the form 5 of stainless steel. The flexibility possessed by the material for the jumper wires 6 is intended to mean a property having a capability of undergoing elastic deformation or plastic deformation. The jumper wires 6 employed in the practice of the present invention has a property capable of undergoing plastic deformation. The electric circuit conductors 8 formed on the mounting portion 20 2 and the electric circuit conductors formed on the rem~ining portion 4 are electrically connected with each other by means of the jumper wires 6, the jumper wires 6 of each pair being situated adjacent the respective side edge 22 or 23 with their opposite ends soldered at H to the associated electric circuit conductor 8 as clearly shown in Fig. 3. In this way, the mounting and remain-25 ing portions 2 and 4 of the printed circuit board P are connected together notonly through the connecting neck 5, but also through the jumper wires 6 positioned sidewise of the connector 1.
Referring now to Fig. 4, if an external force acting in a direction sidewise of the connector as shown by the arrows S acts on the connector 1 30 and is then transmitted to the mounting portion 2 of the printed circuit board P, <6>
the presence of the L-shaped grooves 2-1 and 2-1 substantially surrounding such mounting portion 2 and the flexibility of the iumper wires 6 allow the mounting portion 2 to displace sidewise in a direction conforming to the direction S with the connecting neck S yielded to twist, wherefore the 5 possibility can advantageously be avoided which the electric circuit conductors 8 on the mounting portion 3 may be adversely affected by a relatively large shearing force induced at the solder connections H where, as shown in Fig. 2, the connector 1 and the mounting portion 2 are physically connected.
Moreover, even though the mounting portion 2 is displaced o sidewise in the manner described above, the jumper wires 6 follows the displacement of the mounting portion 2 to undergo a corresponding elastic deformation and, therefore, neither the physical connection between the jumper wires 6 of one pair and the electric circuit conductors 8 on the mounting portion 2 nor the physical connection between the jumper wires 6 of the other pair and 15 the electric circuit conductors on the rem~ining portion 4 will adversely affected.
Thus, the external force so acting on the mounting portion 2 through the connector 1 is sufficiently absorbed by the L-shaped grooves 2-1 and 2-2 around the mounting portion 2 and the jumper wires 6 having a 20 sufficient flexibility as discussed above, so far from being undesirably trans-mitted to the rem~ining portion 4 of the printed circuit board P, and therefore the electric circuit conductors 8 are not adversely affected by the external force so applied.
As hereinbefore discussed, the present invention makes it possible 25 to dispense with the use of any extra component parts such as the supporter 10 required in the practice of the prior art mounting method shown in Fig. 5, no available space will be sacrificed and the product can therefore be manufac-tured at a reduced cost. In addition, since in the illustrated embodiment the only connecting neck 5 is employed as positioned adjacent the rear edge 21 of <7>
the mounting portion 2, the mounting portion 2 can swing and/or twist slightly to absorb the external force applied to the mounting portion 2.
Although the present invention has been fully described in connection with the preferred embodiment thereof with reference to the accompanying drawings which are used only for the purpose of illustration, those skilled in the art will readily conceive numerous changes and modifi-cations within the framework of obviousness upon the reading of the specification herein presented of the present invention. For example, in the foregoing description, the mounting and rem~ining portions 2 and 4 of the o printed circuit board P have been integrally connected together through the connecting neck S positioned adjacent the rear edge 21 of the mounting portion 2. However, the connecting neck may not be always positioned adjacent the rear edge 21 ofthe mounting portion 2, but may be positioned adjacent any one of the other edges of the mounting portion 2, for example, adjacent at least oneof the side edges 22 and 23 of the mounting portion 2.
Also, although the connector 1 has been shown as a DC jack or pin jack connector, the present invention can be equally applicable to an electric connector used to receive a heavy electric component part such as a plug of a switching adaptor (an AC-DC converter).
Accordingly, such changes and modifications are, unless they depart from the scope of the present invention as delivered from the claims annexed hereto, to be construed as included therein.
