Japanese Utility Model Publication No. 07-11747

  However, the connecting device has a possibility that a solder connection failure occurs or a fluorescent lamp is dropped at the time of solder connection and the fluorescent lamp is damaged because solder connection is a manual operation. In addition, since both lead terminals are fixed by solder connection, the solder connection portion or the fluorescent lamp may be damaged when the connection device is attached to the electronic device.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a contact capable of connecting a lead terminal without performing solder connection, and a connection device using the contact. There is.

  In order to solve the above-described problems, a contact according to the present invention is a contact for electrically connecting the first and second lead terminals, and includes a connection portion to which the first lead terminal is connected and an elastically deformable terminal. The second lead terminal includes a pair of clamp arms that are removably clamped in a direction perpendicular to the length direction of the second lead terminal.

  In the case of such a contact, the first lead terminal is connected to the connection portion, while the second lead terminal is inserted between the pair of clamp arms, and the second lead terminal is sandwiched between the pair of clamp arms. Is done. Thereby, the first and second lead terminals are electrically connected. Further, the clamp of the pair of clamp arms is released by moving the second lead terminal in a direction opposite to the pushing direction or by pulling out the second lead terminal in the length direction of the second lead terminal.

  One clamp arm can be a substantially U-shaped plate. In this case, the other clamp arm is a substantially rectangular plate and is inserted between the one clamp arm. In the case of such a clamp arm, the second lead terminal can be contacted and pinched at three points, so that the second lead terminal can be stably held and electrically connected.

  Further, the pair of clamp arms includes a pair of distal end portions that intersect with each other, a pair of first curved portions that are portions connected to the pair of distal end portions and curved away from each other, and the pair of first arm portions. And a pair of second curved portions that are curved in a direction approaching each other, and the second lead terminal is pushed in between the pair of tip portions, and the pair of first curved portions When the bending portion is overcome, the pair of second bending portions sandwich the second lead terminal, and the pair of first bending portions are in contact with the disengaged portion of the second lead terminal. Can do.

  In this case, the second lead terminal is sandwiched between the pair of second curved portions, and a portion of the second lead terminal in the removal direction is in contact with the pair of first curved portions. For this reason, even if the second lead terminal is inadvertently applied with a force in the disengagement direction, the second lead terminal can be prevented from falling out between the pair of clamp arms. In order to remove the second lead terminal, it is necessary to move the pair of first curved portions outward while pushing up the pair of first curved portions against the elastic force of the pair of clamp arms. For this reason, the pair of clamp arms has such a shape that the removal of the second lead terminal requires a larger force than the attachment of the second lead terminal.

  The pair of tip ends of the pair of clamp arms can be provided with a locking means that keeps the pair of tip ends crossed by locking each other. Thus, when the pair of tip portions are maintained in a crossing state by locking the pair of tip portions with each other and applying a preload to each other by the locking means, the second tip portion is interposed between the pair of tip portions. A space for pushing the lead terminal is formed.

  The connection device of the present invention includes the contact and a body in which the contact is built, and the body exposes the contact connection portion and connects the contact to the first lead terminal. An insertion hole for exposing the pair of tip ends of the pair of clamp arms and allowing the second lead terminal to be inserted / removed is provided.

  For this reason, the second lead terminal can be inserted into the insertion hole and can be clamped by the pair of clamp arms of the contact, while the second lead terminal can be moved in the disengagement direction to hold the pair of clamp arms. It can cancel | release and can take out from the said insertion hole part.

  The connection device may further include a pressing member for pressing the second lead terminal into the pair of clamp arms of the contact. In this case, the insertion hole portion includes a first hole portion that extends along the length direction of the pair of clamp arms in order to expose the pair of tip portions of the pair of clamp arms, and the first hole portion. And a second hole provided so as to be continuous with the end in the length direction. A pressing member is inserted into the second hole.

  In this case, the second lead terminal is inserted into the first hole portion and the second hole portion of the insertion hole portion, and is set between the pair of tip portions of the pair of clamp arms. In this state, when the pressing member is inserted into the second hole, the second lead terminal is pressed by the pressing member and is held between the pair of clamp arms.

  The connection device may further include a cover that covers the body. In this case, the pressing member can be provided on the surface facing the insertion hole of the cover. For this reason, when the cover is put on the body, the pressing member of the cover is inserted into the second hole of the insertion hole of the body. At this time, the pressing member pushes down the second lead terminal and clamps it between the pair of clamp arms.

  In the case of the contact according to the present invention, the first lead terminal is connected to the connecting portion, while the second lead terminal is sandwiched between the pair of clamp arms, so that the first lead terminal can be connected without soldering. First and second lead terminals can be connected. Moreover, when the second lead terminal is a lead terminal of an electronic component (for example, a cold cathode fluorescent lamp), the connection can be easily performed by simply holding the second lead terminal between the pair of clamp arms. The possibility of dropping and damaging electronic components during connection can be reduced.

  In addition, the pair of clamp arms includes a pair of tip portions that intersect each other, a pair of first curved portions that are continuous with the pair of tip portions and that are curved away from each other, and the pair of first arms. When the second lead terminal is pushed in between the pair of tip ends of the pair of clamp arms, the second lead terminal is a portion that is continuous with the curved portion and has a pair of second curved portions that are curved toward each other. When the pair of first curved portions is overcome, the second lead terminal is sandwiched between the pair of second curved portions, and the disengaged portion of the second lead terminal is the pair of first curved portions. Abuts against the part. Therefore, even if the second lead terminal is inadvertently applied with a detaching force, it can be prevented from falling off between the pair of clamp arms, and a stable electrical connection with the second lead terminal can be achieved. be able to.

  According to the connecting device of the present invention, the pair of clamp arms of the contact can insert / remove the second lead terminal in the direction orthogonal to the length direction, and the second lead terminal falls off as described above. Therefore, it is possible to connect the second lead terminal in a state where the connection device is attached to the electronic device, and the disconnection or the electronic component connection part (solder part) can be performed. Can also be prevented.

  In addition, the insertion hole provided in the body has a first hole extending along the length direction of the pair of clamp arms in order to expose the distal ends of the pair of clamp arms, and the first hole In the case of a shape having a second hole portion provided so as to be continuous with an end portion in the length direction of the hole portion, the second lead terminal is connected to the first hole portion of the insertion hole portion and the second hole portion. In this state, when the pressing member is inserted into the second hole, the pressing member presses down the second lead terminal and presses between the pair of tip ends of the pair of clamp arms. be able to. That is, by inserting the pressing member into the second hole portion of the insertion hole portion, the second lead terminal can be held between the pair of clamp arms, so that the second lead terminal can be attached very easily. Become.

  Further, if the pressing member is provided on the insertion hole portion facing surface of the cover, the pressing member of the cover pushes down the second lead terminal by covering the body with the cover, and a pair of clamp arms. It can be pushed in between the tips. Therefore, the mounting operation of the second lead terminal can be simplified and the number of parts can be reduced, so that the cost can be reduced.

Then, a jig (not shown) is inserted from the housing portion 221 of the body main body 220 of the body 200, and the second conductor portion 22 of the second lead terminal 20 is applied to the urging force of the first and second clamp arms 130a and 130b. Lift up against. Then, as shown in FIG. 7 (b), the first conductors 22 of the second lead terminals 20 cause the first curved portions 132a and 132b of the first and second clamp arms 130a and 130b to move outward. Pressed. Thereafter, when the second conductor portion 22 of the second lead terminal 20 gets over the first curved portions 132a and 132b, the second conductor portion 22 is moved to the tip portions of the first and second clamp arms 130a and 130b. It can be taken out between 131a and the tip 131b. Alternatively, the second lead terminal 20 is pulled out in the length direction.

  In the case of such a connection device, the first conductor portion 12 of the first lead terminal 10 is connected to the connection portion 120 of the contact 100, while the second conductor portion 22 of the second lead terminal 20 is connected to the contact 100. The first and second clamp arms 130a and 130b are sandwiched between the first and second clamp arms 130a and 130b. Therefore, the first and second lead terminals 10 and 20 can be connected without performing solder connection. Moreover, the second lead terminal 20 can be connected only by holding the second conductor portion 22 of the second lead terminal 20 between the first and second clamp arms 130a and 130b of the contact 100. The possibility of dropping and damaging the cold cathode fluorescent lamp of the second lead terminal 20 at the time of connection can be reduced.

  Further, the first and second clamp arms 130a and 130b of the contact 100 are first portions 131a and 131b that intersect with each other, and a first portion that is a portion continuous with the front end portions 131a and 131b and is curved in a direction away from each other. It has a shape having curved portions 132a and 132b and second curved portions 133a and 133b that are continuous with the first curved portions 132a and 132b and are curved in the approaching direction. For this reason, the second conductor portion 22 of the second lead terminal 20 is pushed in between the tip portions 131a and 131b of the first and second clamp arms 130a and 130b, and gets over the first curved portions 132a and 132b. The second conductor portion 22 is sandwiched between the second curved portions 133a and 133b, and the second conductor portions 22 are in contact with the second curved portions 133a and 133b intersecting each other in the direction of disengagement. The space in the direction of contact is closed. Therefore, even if the second lead terminal 20 is inadvertently applied with a force in the detaching direction (upward direction), it can be prevented from falling out between the first and second clamp arms 130a and 130b. A stable electrical connection between the second lead terminal 20 and the contact 100 can be achieved.

  Further, since the pressing member 310 is provided on the ceiling surface of the cover 300, the pressing member 310 is inserted into the insertion hole of the body main body 220 by rotating the cover 300 and covering the body main body 220 of the body 200. The second lead that fits into the two second holes 224b of the portion 224 and is placed on the intersecting portion between the tip 131a and the tip 131b of the first and second clamp arms 130a and 130b. The second conductor portion 22 of the terminal 20 is pressed down. That is, the second conductor portion 22 of the second lead terminal 20 can be held between the first and second clamp arms 130a and 130b simply by covering the body body 220 with the cover 300, thereby reducing the number of parts. In addition, the mounting operation of the second lead terminal 20 can be simplified, and as a result, the cost can be reduced.

  The contact is a contact for electrically connecting the first and second lead terminals, a connection portion to which the first lead terminal is connected, an elastically deformable terminal, and the second lead terminal. As long as the lead terminal has a pair of clamp arms that can be inserted and removed in a direction perpendicular to the length direction of the second lead terminal, the design may be changed in any way.

  Any connection portion 120 may be used as long as it can electrically connect the first lead terminal 10. For example, the connecting portion 120 can be a clamp arm that holds the first conductor portion 12 of the first lead terminal 10, or the notch portion of the base portion 110 has a first portion of the first lead terminal 10. One conductor portion 12 can be inserted and held.

  The first clamp arm 130a is substantially U-shaped, but is not limited thereto. That is, it is possible to form a rectangular plate similar to the second clamp arm 130b. The first and second clamp arms 130a and 130b are leaf springs. However, the present invention is not limited to this, and any one can be used as long as it can sandwich the second conductor portion 22. You can use it.

  The first curved portions 132a and 132b may be shapes that are curved away from each other, and when the second curved portions 133a and 133b grip the second conductor portion 22 of the second lead terminal 20, It is not necessary to cross each other.

  The second curved portions 133a and 133b may have any shape that can sandwich the second conductor portion 22 of the second lead terminal 20.

  The tip portions 131a and 131b do not need to be linear, and need only intersect so that the second conductor portion 22 of the second lead terminal 20 can be pushed in. In addition, the tip portions 131a and 131b are maintained in an X-shaped crossing manner when the locking piece 131b1 of the tip portion 131b is abutted and locked to the tip portion 131a. A locking piece may be provided so as to be maintained in an intersecting state by coming into contact with the tip 131b, or the first and second clamp arms 130a and 130b may be crossed so that the tips 131a and 131b intersect. A part may be curved.

  Regarding the body 200, a contact can be built-in, the contact connecting portion is exposed, the recess for connecting to the first lead terminal, and the pair of tip ends of the pair of clamp arms of the contact are exposed. What is necessary is just to be provided with the insertion hole part for enabling the insertion / removal of the two lead terminals. Therefore, providing the base 210 is optional.

  Although the insertion hole 224 includes the first hole 224a, the second hole 224b, and the third hole 224c, it is sufficient that the insertion hole 224 includes at least the first hole 224a. The second hole 224b only needs to be provided so as to be continuous with the first hole 224a, and only one of them may be provided.

  Whether or not the cover 300 is provided is arbitrary. Further, the cover 300 is rotatably attached to the body main body 220, but any cover may be used as long as the cover 300 can be covered from above. Furthermore, although the pressing member 310 is provided on the ceiling surface of the cover 300, the pressing member 310 can be a separate body. Further, when the insertion hole 224 is not provided with the second hole 224b, it is not necessary to provide the pressing member 310.

  In addition, although the said connection apparatus was demonstrated as a socket of a cold cathode fluorescent lamp, it is not limited to this, It adapts as other connection apparatuses, such as a connector which electrically connects the 1st, 2nd lead terminal. It is an ability.
