Description

  The present invention relates to a contact and a connector, for example, a contact and a connector for electrically connecting a fluorescent tube used as a backlight of a liquid crystal display device and a printed board.

  Conventionally, a connector including a terminal, a fixed housing, a movable housing, and a lid is known (see Patent Document 1 below).

  The terminal includes a fixing portion, a lead support fixing portion, a substrate contact portion, and an expansion / contraction absorption portion. The fixed part is fixed to the fixed housing. The lead support fixing part is substantially a tuning fork, and contacts the lead wire of the fluorescent tube to support the lead wire. The board contact portion contacts a part of the inverter board. The stretchable absorption part connects the fixed part and the lead support fixing part so that the lead support fixing part can move in the longitudinal direction of the fluorescent tube.

  The fixed housing accommodates the terminal, the fixed portion of the terminal is fixed, and a part of the inverter board is received.

  The movable housing is movably mounted on the fixed housing.

  The lid is rotatably attached to the movable housing.

  To electrically connect the inverter board and the fluorescent tube using the connector described above, first, part of the inverter board is inserted into the board insertion port of the fixed housing, and the inverter board is brought into contact with the board contact portion of the terminal. .

  Next, the lid is rotated to open the lid, and the lead wire of the fluorescent tube is brought into contact with the lead support fixing portion of the terminal from above the movable housing.

  Thereafter, the lid is rotated in the reverse direction to close the lid. At this time, the inner surface of the lid presses the lead support fixing portion, and the lead support fixing portion holds the lead wire. As a result, the inverter substrate and the fluorescent tube are electrically connected, power is supplied from the inverter substrate to the fluorescent tube, and the fluorescent tube is turned on.

  When the fluorescent tube is turned on, heat is generated in the fluorescent tube, and the heat causes the fluorescent tube to thermally expand in the longitudinal direction.

  Since the expansion / contraction absorbing portion of the terminal extends in the longitudinal direction of the fluorescent tube in accordance with the thermal expansion of the fluorescent tube, the lead support fixing portion of the terminal follows the thermal expansion of the fluorescent tube, and the fluorescent tube is hardly damaged.

Is sandwiched. As a result, the fixed housing 5 is fixed to the back plate 23.

  Next, the usage of the above-described connector will be described.

  As shown in FIG. 12, the lower part of the movable housing 7 is inserted into the opening 50 of the fixed housing 5, and the first contact portions 33 of the contacts 3, 3 ′ are inserted into the first contact portion receiving chambers 71, 71 of the movable housing 7. 33 is accommodated. At this time, the electrode insertion groove 73 of the movable housing 7 faces the electrode insertion portion 335 formed between the first contact piece 331 and the second contact piece 332 in the front-rear direction.

  The first contact pieces 331 of the contacts 3 and 3 ′ relatively move along the partition wall 72, and the tips of the engagement pieces 333 slide relative to each other on the cam surface 711.

  Further, the electrode insertion portion 335 between the first contact piece 331 and the second contact piece 332 moves relative to the electrode insertion groove 73 while facing the electrode insertion groove 73.

  When using the connector 1 described above, first, as shown in FIG. 12, the electrode 211 of the fluorescent tube 21 is inserted between the first contact piece 331 and the second contact piece 332 and abuts against the electrode holding portion 334. . At this time, the end of the fluorescent tube 21 enters the notch 54 of the fixed housing 5 and the fluorescent tube housing chamber 74 of the movable housing. Further, the distal end portion of the engagement piece 333 of the contacts 3 and 3 ′ is positioned on the lower surface 711 c of the cam surface 711 of the movable housing 7 and is engaged with the inclined surface 711 a, and the upper half of the movable housing 7 is the fixed housing. Projecting upward from 5.

  Next, the movable housing 7 is pushed down. When the movable housing 7 is pushed down, as shown in FIG. 13, the distal end portion of the engagement piece 333 relatively moves from the lower surface 711c of the cam surface 711 through the inclined surface 711a to the upper surface 711b. As a result, the tip of the second contact piece 332 is pressed and moved toward the first contact piece 331, and the electrode 211 of the fluorescent tube 21 is connected to the first contact piece 331 and the second contact with a larger force than before the movable housing 7 is pushed down. The contact force between the electrode 211 and the first contact portion 33 is increased by being sandwiched between the contact pieces 332. In this way, the fluorescent tube 21 and the printed circuit board 22 are more reliably connected, and the fluorescent tube 21 is lit.

  When the movable housing 7 is pushed down, the distal end portion of the engagement piece 333 is engaged with the engagement protrusion 711d provided at the boundary portion between the inclined surface 711a and the upper surface 711b. The state where 7 is pushed down is maintained. Further, the lower surface of the movable housing 7 is close to and opposed to the expandable portion 352 of the contact 3, 3 ′ in the vertical direction, and the third plate-shaped portion 354 enters a clearance groove 76 provided on the lower wall of the movable housing 7. .

  According to the first embodiment, when the fluorescent tube 21 is thermally expanded and the electrode 211 is extended along the longitudinal direction L, the expansion / contraction part 352 of the contacts 3, 3 ′ is extended, and the first contact part 33 and this are connected. The accommodated movable housing 7 moves in the front-rear direction which is the longitudinal direction L of the fluorescent tube 21 with respect to the fixed housing 5. As a result, the fluorescent tube 21 can be prevented from being damaged due to thermal expansion.

  Further, the heat generation of the fluorescent tube 21 causes the printed circuit board 22 to thermally expand in a first direction D1 (left and right direction) parallel to the longitudinal direction of the printed circuit board 22, and a pad or the like (not shown) on the printed circuit board 22 moves. Since the first vertical portion 362 of the second connecting portion 36 bends, the second contact portion 34 follows the movement of the pad. As a result, it is possible to prevent the pad from being scraped by the second contact portion 34, to prevent positional displacement between the second contact portion 34 and the pad, and to suppress an increase in electrical resistance.

  Further, the connecting piece 343 of the second contact portion 34 is connected to the second vertical portion 364 of the second connecting portion 36, and the second connecting portion 36 and the second contact portion 34 are connected along the longitudinal direction L (front-rear direction). Since they are arranged, the length of the first vertical portion 362 is made relatively long to increase the elastic deformation (flexure) ability of the second connecting portion 36, and the followability of the second contact portion 34 to the pad on the printed circuit board 22 is improved. However, the height of the contact 3 can be reduced, and the height of the contact 1 can be reduced.

  Moreover, the fixing | fixed part 31 is located in the fluorescent tube 21 arrangement | positioning side (back) of the 1st contact part 33, and the fixing | fixed part 31 and the 1st contact part 33 are located in a line along the longitudinal direction L (front-back direction). Therefore, the height of the contact 3 can be further reduced, and the connector 1 can be miniaturized.

Furthermore, since the second contact portion 34 has a clip shape, the insertion portion 222 of the printed circuit board 22 can be more reliably sandwiched.

  A connector contact 203 of a second embodiment of the present invention will be described with reference to FIG. Portions common to the first embodiment are denoted by the same reference numerals, and description thereof is omitted.

  Since the second horizontal portion 2363 of the second connecting portion 236 of the contact 203 has a zigzag shape as will be described later, the contact 203 is different from the contact 3 of the first embodiment.

  The second connection part 236 includes a first horizontal part 361, a first vertical part 2362, a second horizontal part 2363, and a second vertical part 2364. The upper end of the first vertical portion 2362 is connected to the first horizontal portion 361, and the lower end of the first vertical portion 2362 is the left end of the second horizontal portion 2363 (the left end of the second horizontal portion 2363 when the contact 203 is viewed from the front). ). The second horizontal portion 2363 is formed in a zigzag shape. The upper end of the second vertical portion 2364 is connected to the right end of the second horizontal portion 2363 (the right end of the second vertical portion 2364 when the contact 203 is viewed from the front), and is connected to the front side portion of the second vertical portion 2364. The right side of the connecting piece 343 of the contact portion 34 (the right side of the connecting piece 343 when the contact 203 is viewed from the front) is connected.

  In the first embodiment, the first vertical portion 362 is mainly bent in the thickness direction so that the second contact portion 34 can follow the expansion and contraction of the printed board 22 in the first direction D1 (left-right direction). However, in the second embodiment, the second contact portion 34 can follow the expansion and contraction of the printed circuit board 22 mainly by the second horizontal portion 2363 extending or contracting in the first direction D1 (left-right direction). Has been.

  According to 2nd Embodiment, there exists an effect similar to 1st Embodiment.

  The connector 1 according to the first and second embodiments includes the fixed housing 5 and the movable housing 7. For example, if the fixing portion 31 of the contacts 3 and 203 is directly fixed to the back plate 23, the fixed housing is provided. 5 and the movable housing 7 can be omitted, or one of the fixed housing 5 and the movable housing 7 can be adopted.
