DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a receiving connector, and more particularly, to a receiving connector for receiving a sending connector among connectors used for joining printed wiring boards and electronic equipment.

[0002]

2. Description of the Related Art FIG. 2 shows a conventional example. In FIG. 2, reference numeral 50 indicates a feed-side connector, and reference numeral 56 indicates a guide member of the receiving-side connector. The guide member 56 of the receiving-side connector is formed of a conductive material, and is connected to a similarly conductive connector body (not shown). Further, the guide member 56 has a loop-shaped convex portion which is in contact with the feed-side connector 50 on the distal end side. On the other hand, the sending-side connector 50 is mainly composed of a conductive layer 53, and its tip is covered with an insulating layer 55, and further over it is covered with a resistance layer 54.

[0003] In joining the two connectors,
The leading end of the feed connector 50 is inserted so as to be inserted into the loop-shaped convex portion of the guide member, and is pushed as it is until the leading end contacts the receiving connector main body. At this time, the rush current generated at the contact point between the sending connector 50 and the guide member 56 is effectively suppressed by the resistance layer 54 coated on the conductive layer 53 of the sending connector 50. Such an inrush current suppression technique is disclosed in, for example, Japanese Patent Application Laid-Open No. 63-116380.

[0004]

However, in the above-mentioned conventional example, the resistance layer 54 is rubbed against the loop-shaped projection every time the feed-side connector 50 is inserted and removed, so that the resistance layer 54 and the insulating layer 55 are formed. May be worn. In such a case, there is a disadvantage that an inrush current flows from the worn portion. In addition, there is a problem in that the conductive layer 53 is further worn due to friction of the abraded portion and the conductive layer 53 is cut.

[0005]

SUMMARY OF THE INVENTION It is an object of the present invention to improve the disadvantages of the prior art and, in particular, to provide a receiving connector which effectively prevents the occurrence of inrush current and has excellent durability.

[0009]

According to the first aspect of the invention, when the sending connector is inserted between the guide members on the receiving side, the sending connector first contacts the first contact portion furthest from the receiving conducting member. Next, when the sending-side connector is further pushed toward the receiving-side conducting member, the sending-side connector sequentially contacts the second, third,... Contact portions closer to the receiving-side conducting member, Finally, it is connected to the receiving-side conducting member.

[0012]

An embodiment of the present invention will be described below with reference to FIG.

In FIG. 1, the receiving-side conducting member 1 includes one and the other guide members 2 and 2 projecting from the receiving-side conducting member 1 and guiding the sending-side connector 3 to the receiving-side conducting member 1. ing. The one and the other guide members 2, 2 are formed of a resistance material, and a plurality of contact portions 2b which contact the feed connector 3 are provided on opposing surfaces 2a, 2a along the guide direction of the feed connector 3 and at predetermined intervals. They are formed at intervals.

Hereinafter, the structure of the present embodiment will be described in more detail. A plurality of contact portions 2b are formed at positions corresponding to the one and the other guide members 2 respectively. Further, the plurality of contact portions 2b are arranged such that their intervals are
Are formed closer to each other. In this embodiment, the receiving connector 10 and the sending connector 3 have a width in the depth direction of FIG. 1 and are formed in a flat plate shape. For this reason, actually, by providing a plurality of grooves in the depth direction of FIG. 1 on the opposing surfaces of the one and the other guide members 2, the protruding portions are formed as the plurality of contact portions 2 b. Have been.

The receiving-side conducting member 1 is adapted to input a signal from the sending-side connector 3 to an electronic component (not shown) on the receiving side. The receiving-side conductive member 1 is formed to have a concave cross-section, and a contact point 1a with the feed-side connector 3 is formed in the concave portion. Further, each of the concave projecting portions has a slit in the projecting direction, and a connection portion of the guide members 2 and 2 with the receiving-side conducting member 1 is inserted therein.
It is fixed in an electrically connected state. Here, the opposing surfaces of the guide members 2 and 2 and the wall surface forming the depression of the receiving-side conductive member 1 are in a straight line. On the other hand, the feed-side connector 3 is a general one that has been conventionally used, and has a conductive member formed in a plate shape.

Next, the overall operation of this embodiment will be described.

When the sending connector 3 is inserted between the guide members 2 of the receiving connector 10, the sending connector 3 first contacts the first contact portion 2 a farthest from the receiving conductive member 1. At this time, an inrush current is generated due to the potential difference and the capacity generated between the sending connector 3 and the receiving connector 10, but the amount of the inrush current is reduced by the action of the guide members 2, 2 made of a relatively large resistance material. Limited.

Here, assuming that the sending-side connector 3 immediately contacts the contact portion 1a of the receiving-side conducting portion 1 immediately thereafter, the voltage drop caused by the guide members 2 and 2 is short-circuited at once, resulting in an excessive rush current. Will flow. However, in the present embodiment, the sending connector 3 is guided to the receiving conducting member 1 while being sandwiched from both sides by the contact portions 2a and 2b provided between the guide members 2 and 2, so that the sending connector 3 is , The second, third,... Closer to the receiving-side conducting member 1.
Contact portions 2b, 2b,.

At this time, the rush current generated by the contact with the new contact portion 2b is limited similarly to the first contact portion 2a. Further, as the contact point approaches the receiving-side conducting member 1, the resistance between the receiving-side conducting member 1 and the sending-side connector 3 gradually decreases. Then, it is finally connected to the receiving-side conducting portion 1.

As described above, according to the present embodiment, the guide members 2 and 2 are formed of a resistance material, and a plurality of contact portions 2a and 2b with the feed connector 3 are formed in the guide direction of the feed connector 3. As a result, the rush current generated in the contact portions 2a and 2b during the process of inserting the feed-side connector 3 can be suppressed, and the resistance value between the feed-side connector 3 and the receiving-side conductive member 1 is gradually reduced. However, since it can be finally connected to the receiving side conductive member 1, the generated inrush current can be minimized. In addition, it is possible to effectively prevent a situation in which an unexpected rush current is generated due to wear of the resistance material as in the related art.

Further, since the plurality of contact portions 2a and 2b are formed at the positions corresponding to the one and the other guide members 2 respectively, the feeding connector 3 can be stably inserted. Further, since the plurality of contact portions 2b are formed so as to be closer to the receiving side conductive member 1, even if the frictional resistance is small and the insertion proceeds smoothly even after the insertion of the feed side connector 3, each contact at this time. Parts 2a, 2
After the inrush current generated at the point b is stabilized, it can be brought into contact with the next contact point 2b, whereby the amount of the generated inrush current can be further suppressed.

[0022]

Since the present invention is constructed and functions as described above, according to the present invention, the guide member is formed of a resistance material, and the contact portion with the feed connector is formed in a plurality in the guide direction of the feed connector. As a result, the rush current generated in the contact portion during the process of inserting the feed-side connector can be suppressed, and the resistance between the feed-side connector and the receiving-side conducting member can be reduced while gradually reducing the resistance value. Since it can be connected to the side conductive member, the generated inrush current can be minimized. In addition to this, it is possible to effectively prevent a situation in which an unexpected rush current is generated due to wear of the resistance material as in the related art.

According to the second aspect of the present invention, since the plurality of contact portions are formed at the positions corresponding to the one and the other guide members, the feed-side connector can be stably inserted.

Furthermore, according to the third aspect of the present invention, since the plurality of contact portions are formed closer to the receiving-side conductive member, the frictional resistance is small and the insertion proceeds smoothly after the feed-side connector is inserted. Even in this case, the rush current generated at each contact portion at this time can be brought into contact with the next contact point after the rush current is stabilized, whereby the amount of rush current generated can be further suppressed.

As described above, it is possible to provide an unprecedented superior receiving connector.
