Description

  The present invention relates to a connection device and an LED lighting device, and is suitable for application to, for example, an interior lamp of an automobile.

  Generally, a tungsten light bulb is used as an interior lamp of an automobile. In recent years, a board with LED (Light-Emitting Diode) mounted (hereinafter referred to as an LED board) has been adopted as a car interior light that has advantages such as longer life, higher brightness and lower power consumption than this tungsten bulb. There is a case.

  In this case, a connecting device (hereinafter referred to as a socket adapter) for connecting the LED board to an indoor lamp socket (hereinafter referred to simply as a lamp socket) of an automobile is used.

  Lamp socket types (types) can be broadly classified into straight tube type lamp sockets, screw-in type lamp sockets, and wedge base type lamp sockets according to the type of automobile, and sockets corresponding to these lamp socket types. Each adapter is molded.

  For example, Utility Model Registration No. 3120848 discloses a socket adapter (clamping connection terminal 1) corresponding to a straight tube lamp socket, a socket adapter (rotary built-in connection terminal 2) corresponding to a screw-type lamp socket, and a wedge. Socket adapters (insertion-type connection terminals 3) corresponding to base-type lamp sockets are disclosed.

  However, even in the same type of lamp socket, there are many differences in the structure of the lamp socket depending on the type of automobile. When focusing on a straight tube lamp socket, one of the differences is the distance between one socket terminal piece and the other socket terminal piece facing the one socket terminal piece (hereinafter referred to as the socket). Called terminal length).

  In the socket adapter corresponding to the straight tube lamp socket disclosed in the above publication, the width between the metal pieces (metal cap 12) at both ends is fixed, so that it corresponds to the width between the metal pieces at both ends. There was a problem that it could not be installed other than a lamp socket having a length between socket terminals.

  The present invention has been made in consideration of the above points, and intends to propose a connecting device and an LED lighting device that can be attached to lamp sockets of the same type but different structures.

  In order to solve such a problem, the present invention provides a connection for connecting a board (11) on which an LED is mounted to a socket terminal piece (S1 and S2, S3 and S4) of a pair of vehicle interior lights arranged opposite to each other. An instrument (21), which is a hollow insulating rod-shaped member (41), and an insulating core member (42) that slides in the hollow of the rod-shaped member so as to be expandable and contractable from one end of the rod-shaped member; At least the surface is insulative, spirally wound along the outer peripheral surface of the rod-shaped member, and an elastic member (32) that urges the core member in the expansion / contraction direction, and the other end of the rod-shaped member and one end of the elastic member The first metal terminal (33A) to be supported and the second metal terminal (33B) to be supported at the end of the core member and the other end of the elastic member were provided.

  Further, the present invention is an LED lighting device (1) connected to socket terminal pieces (S1 and S2, S3 and S4) of a pair of vehicle interior lights opposed to each other, and a board (11) on which an LED is mounted. And a connecting device (21) for connecting the substrate to the socket terminal piece. The connecting device is made of a hollow insulating rod-shaped member (41) and is extendable from one end of the rod-shaped member. And an insulating core member (42) that slides in the hollow of the rod-shaped member, and at least the surface is insulative, is wound spirally along the outer peripheral surface of the rod-shaped member, and is attached in the expansion / contraction direction of the core member. The elastic member (32) to be energized, the first metal terminal (33A) supported by the other end of the rod-like member and one end of the elastic member, and the second supported by the end of the core member and the other end of the elastic member. A metal terminal (33B) was provided.

  In this connection device, since the rod-shaped member and the core member support the first terminal and the second terminal so as to be expandable and contractable in the approaching direction or the separation direction, the width between the terminals can be changed with one connection device. A plurality of socket terminal lengths can be accommodated. In addition, when the connection tool is mounted on the socket terminal piece via the first metal terminal and the second metal terminal, the first force is applied to the socket terminal piece by the biasing of the elastic member in the expansion and contraction direction of the core member. The connection between the terminal and the second terminal can be held firmly. In this way, it is possible to realize a connection fixture and an LED lighting device that can be attached to lamp sockets of the same type but different structure.

  Hereinafter, an embodiment of the present invention will be described in detail with reference to the drawings.

  In FIG. 1, reference numeral 1 denotes an LED illumination device as a whole, which is composed of a room lamp body 2 and a socket adapter 3.

  The room lamp body 2 includes an LED substrate 11 and a male connector 12 connected to the ends of a pair of lead wires routed from the LED substrate 11, and leads are connected to the male connector 12. The LED is driven using the voltage applied via the driving voltage as a driving voltage.

  The socket adapter 3 includes a socket adapter body 21 corresponding to a straight tube lamp socket, and a female connector 22 connected to the ends of a pair of lead wires routed from the socket adapter body 21.

  As shown in FIG. 2, the socket adapter main body 21 includes a telescopic bar 31, a coil spring 32, and a first metal terminal 33 </ b> A and a second metal terminal 33 </ b> B that are coupled to the respective ends of the telescopic bar 31 and the coil spring 32. It is comprised by.

  As shown in FIGS. 3 (A) and 3 (B), which is a cross-section taken along the line AA 'in FIG. 2, the stretchable bar 31 is made of glass-containing ABS resin in the hollow of the tubular member 41 of glass-containing ABS resin. By inserting the core member 42 slidably, the core member 42 can be expanded and contracted from one end of the circular tubular member 41.

  In addition, a disc-shaped locking portion 41A is integrally formed at one end edge of the circular tubular member 41, and a head portion 42A that is in contact with the locking portion 41A is formed on the core member 42. . As a result, the telescopic bar 31 can reliably avoid separation of the tubular member 41 and the core member 42.

  On the other hand, the coil spring 32 is subjected to a process for thin-film processing the surface of the conductive wire with an insulating material (hereinafter referred to as an insulating process), and the wire material subjected to the insulating process is applied to the tubular member 41. In this manner, the wire is wound in a state where the width between the wires is kept substantially constant.

  Accordingly, the coil spring 32 is disposed substantially concentrically with respect to the central axis of the tubular member 41 (core member 42) as shown in FIG. 3C, which is a cross section taken along line BB 'in FIG. The

On the other hand, the first metal terminal 33A and the second metal terminal 33B have the same shape, and as shown in FIGS. 2, 3A, and 3B, the truncated cone-shaped tip portion TP _A (TP _B ) And the annular abdomen BE _A (BE _B ) are integrally formed to form a cap shape as a whole.

Further, flanges FR _A and FR _B are formed on the opposite ends of the abdominal portions BE _A and BE _B in the first metal terminal 33A and the second metal terminal 33B on the opposite side to the opposite side.

The first metal terminal 33A and the second metal terminal 33B are fixed by soldering at the tip of the corresponding lead wire with a part of the inner wall as a contact, and the inner space is an insulating member IL _A such as paraffin, Filled with IL _B.

The insulator IL _A filled in the inner space of the first metal terminal 33A is embedded with the end (open end) of the core member 31 with reference to the center of the abdomen BE _{A and} the center axis AX of the core member 42. (Fig. 3 (A), (B), etc.). On the surface of the insulator IL _A, it is connected by one end of the coil spring 32 is fixed by adhesive or the like (FIG. 2, etc.).

Similarly, the other end of the tubular member 41 is embedded in the insulating member IL _B filled in the inner space of the second metal terminal 33B with reference to the center of the abdomen BE _{B and} the central axis AX of the tubular member 41. The other end of the coil spring 32 is fixed to the surface of the insulator IL _B.

Therefore, the first metal terminal 33A and the second metal terminal 33B are supported by the stretchable bar 31 and the coil spring 32 so as to be stretchable in directions toward and away from each other with the abdominal portions BE _A and BE _B facing each other. It is made to be done.

Further, since the first metal terminal 33A and the second metal terminal 33B are supported by the insulating elastic bar 31 and the coil spring 32 subjected to the insulation process through the insulators IL _A and IL _B , Without providing an insulating cover around the telescopic bar 31 and the coil spring 32, energization between the metal terminals can be reliably avoided even when vibration of the vehicle body occurs. Yes.

Here, as shown in FIG. 3C, the diameter of the coil spring 32 is selected to be smaller than the diameters of the abdominal portions BE _A and BE _B in the first metal terminal 33A and the second metal terminal 33B. Yes.

  As a result, the socket adapter main body 21 can be reduced in size and made smarter as a whole while minimizing the amount of wire in the coil spring 32 (FIG. 2 and the like).

In the above configuration, as shown in FIG. 4, when the LED lighting device 1 is mounted on the U-shaped socket terminal pieces S1 and S2, the first metal terminal 33A and the second metal terminal 33B are used as the first stage. By applying a pressing force in the direction in which the abdomen approaches, the width L1 between the abdominal parts BE _A and BE _B is adjusted to the length L2 between socket terminals.

  At this stage, if a pressing force is not applied in the direction in which the metal terminals 33A and 33B approach the central axis AX of the socket adapter main body 21, the coil spring 32 may contract in a direction different from the central axis direction. The socket adapter body 21 can restrict the contraction direction of the coil spring 32 to the contraction direction of the extension bar 31 by inserting the extension bar 31 into the coil spring 32.

Therefore, this socket adapter main body 21 can adjust the width L1 between the abdominal parts BE _A and BE _B to the socket terminal length L2 by a simple operation of pinching each metal terminal 33A and 33B with one hand.

As a second stage, the abdominal portions BE _A and BE _B of the respective metal terminals 33A and 33B are fitted into the U-shaped socket terminal pieces S1 and S2. At this stage, the abdominal portions BE _A and BE _{B of} each metal terminal 33 are formed in an annular shape, so that friction when fitted into the socket terminal pieces S1 and S2 can be reduced.

  Therefore, the socket adapter main body 21 is configured such that each metal terminal 33A, 33B in the socket adapter main body 21 adjusted to the length L2 between the socket terminals is held in the U-shaped socket terminal piece while holding the metal terminals 33A, 33B with one hand. It can be easily fitted in S1 and S2.

  Moreover, when each metal terminal 33A, 33B is clamped by being fitted in U-shaped socket terminal pieces S1, S2, as shown in FIG. 5, the socket adapter main body 21 is separated from each metal terminal 33A, 33B. The coil spring 32 is urged in the direction (stretching direction of the core member 42), whereby the connection of the metal terminals 33A and 33B to the socket terminal pieces S1 and S2 can be firmly held. Therefore, the socket adapter main body 21 can further reduce the fact that the socket adapter main body 21 comes off in accordance with the vibration of the vehicle body.

In addition to this, the flanges FR _A and FR _B formed on each metal terminal 33 are engaged with the U-shaped socket terminal pieces S1 and S2, so that the coil springs against the clamping force of the socket terminal pieces S1 and S2 Even when the urging force of 32 is increased, the connection of each metal terminal 33 to the socket terminal pieces S1, S2 can be maintained.

  Thereafter (FIG. 4), the LED substrate 11 is fixed to the top surface cf of the U-shaped pedestal PD for filling the gap between the lamp cover CV and the LED substrate 11 with double-sided tape or the like, and the fixed pedestal DZ is illuminated. The illumination cover CV is fitted into the illumination lamp panel PN while being inserted between the lamp panel PN and the lamp cover CV.

  Further, as shown in FIG. 6, when the LED lighting device 1 is attached to the socket terminal pieces S3 and S4 having holes, the first metal terminal 33A and the second metal terminal 33B come closer as a first step. By applying a pressing force in the direction, the width L3 of the socket adapter body 21 is adjusted to the socket terminal length L4.

As the second stage, in the socket adapter main body 21 adjusted to the socket terminal length L2, the conical tip portions TP _A and TP _B of the metal terminals 33 (33A and 33B) are placed in the holes of the socket terminal pieces S3 and S4. It is fitted by being inserted.

  As described above, the socket adapter body 21 has a structure that can be adjusted according to the lengths L2 and L4 between the socket terminals corresponding to the socket terminal pieces S1 and S2, S3 and S4 of different fitting types, and the metal The tip portion TP of the terminals 33A and 33B has a shape corresponding to the socket terminal pieces S3 and S4, and the abdomen BE of the metal terminals 33A and 33B is formed in a shape corresponding to the socket terminal pieces S1 and S2. Thus, it can be attached to socket terminal pieces S1 and S2, S3 and S4 of different fitting types.

  According to the above configuration, the metal terminals 33A and 33B are supported so as to be extendable and retractable in the approaching direction or the separating direction, so that they can be attached to lamp sockets of the same type but having different lengths between socket terminals. The adapter body 21 can be realized.
