  The connector described in Patent Document 1 has a configuration in which a contact is pressed and elastically deformed by pressing a contact by bulging portions disposed on both sides thereof, so that a free end thereof is pressed to sandwich an electrode wire (conductive wire). . However, since this pressure contact is performed only by the elastic force generated by the deformation of the U-shaped portion provided with the free end, there is a problem that it is difficult to obtain a large pressure contact force. In addition, the area where the free end of the contact is in contact with the electrode wire is relatively small, and there is a problem that the electrical connection is not stable. Furthermore, when the U-shaped portion composed of the inner wall portion pressed against the electrode wire and the outer wall portion pressed by the bulging portion is deformed by repeated use or the like, there is a problem that the pressure contact with the electrode wire cannot be properly performed.

  The connector described in Patent Document 2 has a configuration in which a contact portion of a contact provided so as to elastically sandwich an electrode wire is opened and closed by operating a pair of operating pieces attached in the vicinity thereof. However, since the operation of the operation piece is performed by contact with and separation from the cam portion of the actuator provided so as to be rotatable, there has been a problem that the rotation structure increases the size of the connector and makes assembly difficult.

  The connector described in Patent Document 3 includes a contact, a case for housing the cover, and a lid, and the two clamping arms of the lid sandwich the corresponding contact locking portion so that the contact is pressed against the electrode wire. It has the composition to make it. However, since each component (case, lid, and contact) is a separate body before press contact, it is troublesome to handle, and there is a problem that the work load when assembling the connector is large. Furthermore, when the cold cathode tube needs to be replaced after the cold cathode tube is connected to the connector, there is a problem that the removing operation is not easy.

  The connector described in Patent Document 4 has a configuration in which a contact having a pair of opposing elastic pieces is housed in a housing, and an operation of expanding a contact holding portion is performed by vertically moving an operation member. However, the contact has a shape in which the two pieces are connected via the folded portion, and in the free state, the inner piece that forms the clamping portion is arranged in parallel. The clamping force with respect to the electrode wire due to the elastic force of the electrode is relatively small, and there is a problem that the electrode wire cannot be stably held. In this case, it is possible to improve the clamping force by pressurizing the one part by the pressurizing part made of the inclined cam surface provided on the operation member, but this pressurizing part is the tip part of the one part away from the clamping part. Therefore, when the one part is deformed by repeated use or the like, there is a problem that the press contact with the electrode wire cannot be properly performed.

  The present invention has been devised in view of such problems of the prior art, and facilitates the attaching / detaching operation of the cold cathode tube with respect to the connector for the cold cathode tube and improves the pressure contact force of the contact with the electrode wire. It is a main object of the present invention to provide a cold cathode tube connector and a cold cathode tube mounting structure capable of stabilizing electrical connection.

  In order to solve the above problems, a first invention is to provide a contact having a holding part for elastically holding an electrode wire of a cold cathode tube, a housing to which the contact is mounted, and an expansion of the holding part. An operation member that performs an operation, is slidably attached to the housing, and an expansion position where the clamping portion is expanded by the operation member; A slider that moves between an expansion release position for holding a wire, and in an initial state in which the holding portion of the contact is not expanded by the operation member and does not hold the electrode wire of the cold cathode tube, A pair of press contact members are arranged so as to intersect each other when viewed from the axial direction of the electrode wire.

  According to this, since the contact clamping portion is expanded by sliding the slider, it is easy to attach / detach the cold cathode tube to / from the connector. In addition, since the pair of pressure contact members are arranged so as to cross each other when viewed from the axial direction of the electrode line in the initial state of the contact, the pressure contact force against the electrode line is improved and the electrical connection is stabilized. Can do.

  According to a second aspect of the present invention, the pressure contact member includes a plurality of contact pieces that contact the electrode wire, and the contact pieces of the pressure contact members are the electrodes. It can be set as the structure provided so that it might arrange | position alternately along the axial direction of a line.

  According to this, in the configuration having the pressure contact members arranged so that the contact clamping portions intersect with each other in the initial state, the contact state of the pressure contact members (a plurality of contact pieces) with respect to the electrode wires is appropriately secured. Can be held stably.

  A third invention made to solve the above problem is that the plurality of contact pieces are two contact pieces formed on both sides of a slot provided at the center in the width direction of the elastic piece constituting the press contact member. In the initial state, the contact clamping portions may be configured to intersect each other when one of the contact pieces is inserted into a mating slot forming a pair.

  According to this, with a simple configuration, it is possible to stably maintain the contact state while appropriately securing the contact area of the contact piece with the electrode wire.

  A fourth invention made to solve the above-mentioned problems is a contact having a holding part for elastically holding an electrode wire of a cold cathode tube, a housing to which the contact is mounted, and an expansion of the holding part An operation member that performs an operation, is slidably attached to the housing, and an expansion position where the clamping portion is expanded by the operation member; A pair of sliders that move between an expansion release position that clamps the wire, and a pinching portion of the contact that has a pressure contact member that makes a pressure contact with the electrode wire, and the slider presses the pressure contact member And a pressing member that presses a surface of the pressing member opposite to a surface that presses the electrode wire at the release position and releases the pressing at the expanded position. To do.

  According to this, since the contact clamping portion is expanded by sliding the slider, it is easy to attach / detach the cold cathode tube to / from the connector. In addition, the pressing member provided on the slider presses the surface of the pressing member opposite to the surface that presses against the electrode wire, so that the pressing contact state of the pressing member with respect to the electrode wire is reliably maintained and the electrical connection is stabilized. Can be achieved. Further, even when the contact pressure contact member or its peripheral portion is deformed due to repeated use or the like, there is an advantage that the pressure contact member can be appropriately pressed against the electrode wire.

  A fifth invention made to solve the above-mentioned problem is that a contact having a holding part for elastically holding an electrode wire of a cold cathode tube, the contact is mounted, and the cold cathode tube is connected to a power source side. A housing that is held along the surface of the substrate; and an operating member that performs an expansion operation of the clamping portion, and is slidably attached to the housing along the axial direction of the electrode wire, and the operating member And a slider that moves between an expansion position for expanding the holding portion and an expansion release position for releasing the expansion and holding the electrode wire in the contact.

  According to this, since the contact clamping portion is expanded by sliding the slider, it is easy to attach / detach the cold cathode tube to / from the connector. Further, since the slider is slid along the axial direction of the electrode wire (that is, the substrate surface on the power supply side), no large external force is applied in the direction perpendicular to the substrate surface during the sliding. Can reduce the load.

  A sixth invention made to solve the above problem is formed as a housing cover that covers the housing so that the slider does not expose a contact portion between the electrode wire and the contact at the spread release position. It can be configured.

  According to this, since the contact portion between the electrode wire and the contact is covered after the cold cathode tube is attached, it is possible to prevent foreign matter (dust, dust, etc.) from entering and attaching to the connection portion. .

  In a seventh aspect of the present invention made to solve the above-mentioned problem, the slider is in a position where the positional relationship between the electrode wire and the contact can be confirmed in the expanded position, and the slider is in the expanded release position. It can be set as the structure which has the window for visual recognition in the position which does not expose the contact site | part of an electrode wire and the said contact.

  According to this, since the operator can confirm the positional relationship between the electrode wire and the contact when attaching the cold cathode tube to the connector, the attaching operation can be performed easily and reliably. Further, after the cold cathode tube is attached, the contact portion between the electrode wire and the contact is covered, so that foreign matter can be prevented from entering and adhering to the connection portion.

  An eighth invention made to solve the above-described problems is that the cold cathode tube connector according to the fifth to seventh inventions is arranged in a direction perpendicular to the sliding direction of the slider with respect to the substrate on the power source side. A cold-cathode tube mounting structure having a plurality of rows is provided.

  According to this, it is easy to automate the connection operation for multiple cold cathode tubes by providing a mechanism that moves the sliders of multiple cold cathode tubes together from the rear side to move them from the expanded position to the expanded release position. Can be realized.

  According to the present invention, it is possible to easily attach / detach the cold cathode tube to / from the cold cathode tube connector, and to improve the pressure contact force of the contact with respect to the electrode wire, thereby achieving an excellent effect of stabilizing the electrical connection.

  Next, a procedure for attaching the cold cathode tube to the cold cathode tube connector having the above configuration will be described.

  FIG. 7 is a perspective view showing a cold cathode tube mounting method for the cold cathode tube connector shown in FIG. 1, and FIG. 8 is a longitudinal sectional view showing the connector expanding operation when the cold cathode tube is attached (FIG. 10). 9 is a cross-sectional view taken along the line IX-IX in FIG. 8, and FIG. 10 shows the opening / closing operation of the slider when the cold-cathode tube is attached. FIG. 11 is a cross-sectional view taken along line XI-XI in FIG. 8, and FIG. 12 is a cross-sectional view taken along line XII-XII in FIG.

  As shown in FIG. 7, the cold cathode tube connector 1 is attached to the power supply side substrate 70 via its terminal leg pieces. The cold-cathode tube 71 is attached to the cold-cathode tube connector 1 in a state where the slider 5 is moved to the expansion position where the upright piece 14 of the contact 2 is expanded so that the cold-cathode tube 71 can be attached and detached (see FIG. 7 (A)), the end of the cold cathode tube 71 is placed in the holding groove 31 of the cushion 3 from above the cold cathode tube connector 1 (FIG. 7B), and then the expansion is released to contact 2. This is done by moving the slider 5 to the expansion release position where the electrode wire 72 is held between the upright pieces 14 (FIG. 7C).

  Although FIG. 7 shows only a configuration in which one electrode line 72 of the cold cathode tube 71 is connected, the other electrode line can be similarly connected. Further, in FIG. 7, a plurality of similar cold cathode tube connectors are provided in the left and right direction of the cold cathode tube connector 1, and the sliders of the plurality of connectors are collectively pressed from the rear side to cancel the expansion from the expanded position. By providing a mechanism for moving to a position, it is possible to easily realize automation of connection operation for a plurality of cold cathode tubes. In addition, about the removal of the cold cathode tube 71, it can carry out by the reverse procedure to the said attachment.

  Here, when the slider 5 is attached to the housing 4, the hook 66 (FIG. 6) provided on the left and right side walls 62 is engaged with the guide groove 51 of the side wall 42 of the housing 4 from the state shown in FIG. 2. In this state, it is performed by pushing forward (to the housing 4 side). As a result, the hook 66 of the slider 5 is elastically deformed so as to expand to the left and right to get over the convex piece 53 of the housing 4 and the rearward movement is restricted by the convex piece 53 as shown in FIG. It becomes. At this time, the slider 5 is in the expanded position.

  Further, the movement of the slider 5 from the expanded position to the expanded release position is performed by further pushing the slider 5 at the expanded position in FIG. As a result, the hook 66 of the slider 5 is elastically deformed so as to expand to the left and right to get over the convex piece 52 of the housing 4, resulting in the state shown in FIG. At this time, the slider 5 is in the expansion release position. On the other hand, by pulling the slider 5 backward, the hook 66 can get over the convex piece 52 of the housing 4 and the slider 5 can be moved again from the expansion release position to the expansion position. After the slider 5 is once attached to the housing 4 (that is, after the cold cathode tube connector 1 is assembled), the cold cathode tube can be attached / detached only by sliding between the expanded position and the expanded release position. Therefore, it is easy to attach / detach the cold cathode tube 71 to / from the connector 1. In addition, after the cold cathode tube connector 1 is assembled, it is not necessary to handle each component individually even when the cold cathode tube 71 is attached or detached, so that there is an advantage that handling is easy.

  When the slider 5 is in the expanded position, as shown in FIGS. 8 (A) and 9 (A), the operating projection 65 is movable against the elastic force of the upstanding piece 14 of the contact 2. Are pressed in the left-right direction, so that the distance between the left and right contact pieces 25, 26 at the portion N sandwiching the electrode wire 72 is larger than the diameter of the electrode wire 72. At this time, as shown in FIG. 10A, the operator who installs the cold cathode tube 71 confirms the positional relationship of the connection between the electrode wire 72 and the contact pieces 25, 26 from the notch 61 a of the slider 5. Is possible. Thereby, it is possible to easily and reliably execute the operation of attaching the cold cathode tube 71.

  On the other hand, when the slider 5 is in the expansion release position, as shown in FIGS. 8B and 9B, the pressing of the operating protrusion 65 against the movable piece 27 is released, and the upright piece 14 of the contact 2 is released. Due to the elastic force, the distance between the left and right of the contact pieces 25 and 26 in the portion N that sandwiches the electrode wire 72 is narrowed, and the electrode wire 72 is sandwiched. Further, as shown in FIGS. 8B and 11, the pair of holding protrusions 68a and 68b move forward so as to sandwich the contact pieces 25 and 26 from both sides, and the cross section is substantially T-shaped. Those side edge portions expanded in the direction press the surface of the contact pieces 25, 26 opposite to the surface pressed against the electrode wire 72. At this time, as shown in FIG. 10B, the notch 61a of the slider 5 moves to a position where the connection position between the electrode wire 72 and the contact pieces 25 and 26 is not exposed, and foreign matter (dust, Intrusion and adhesion of dust etc. can be prevented.

  FIG. 13 is an explanatory view when a cold cathode tube having a different outer diameter is attached to the cold cathode tube connector shown in FIG.

  When viewed from the axial direction of the electrode wire 72, the press contact portion 22 of the contact 2 has a shape in which the upper and lower ends thereof are constricted inward, thereby preventing the electrode wire 72 from coming off in the vertical direction. is doing. By applying the elastic force of the upright piece 14 in the shape of the pressure contact portion 22 as described above, the contact 2 is an electrode of the cold cathode tube 71 having different outer diameters as shown in FIGS. 13 (A) and 13 (B). The wire 72 can be pressed. In the case of cold cathode tubes having different electrode wire diameters, they can be similarly attached to the cold cathode tube connector 1.

  Although the present invention has been described in detail based on specific embodiments, these embodiments are merely examples, and the present invention is not limited to these embodiments. For example, the connection of the cold cathode tube connector to the substrate is not limited to the configuration shown in the embodiment, and can be performed using various methods well known to those skilled in the art.

  The cold-cathode tube connector and the cold-cathode tube mounting structure according to the present invention facilitate the attaching / detaching operation of the cold-cathode tube to the cold-cathode tube connector and improve the pressure contact force of the contact with the electrode wire to stabilize the electrical connection. Therefore, it is useful as a cold cathode tube connector and a cold cathode tube mounting structure for connecting an electrode wire of a cold cathode tube used as a light source such as a liquid crystal backlight to the power source side.
