[Prior Art] In recent years, the development of an illumination device using a light-emitting diode (hereinafter referred to as "LED") as a light-emitting element (hereinafter referred to as "LED bulb") has been developed. The LED bulb generally has a circuit board on which the LED is mounted. In order to supply power to the circuit board, a connector having a plug-in type of wire is used. The connector is generally fixed to the frame of the fixed holding circuit board by screwing. The work of fixing the connector to the frame by the screwing is not easy to manage the working hours and the tightening torque of the screw, and thus causes problems in the assembly of the lighting device. Japanese New Patent Registration No. 30297752 (Patent Document 1) or Japanese Patent Application Laid-Open No. 3 06 9 7 54 (Patent Document 2) discloses a wire connecting terminal which is formed by processing a conductive member to form a plate portion having a spring property, and A wire is inserted between the plate portions. In the wire connection terminal, one of the pair of plate portions forms a wire holding portion, and the other forms a receiving wire. Flat contact portion. When the electric wire is removed from the electric wire connection terminal, a member that is not the same body is used. That is, the plate portion of the electric wire connection terminal is deformed by operating a member of a different body, so that the electric wire is easily detached. In addition, since the wire connection terminal disclosed in Patent Document 1 or Patent Document 2 is a structure in which a wire is removed by using a member of a different body, there is a problem that the number of parts is increased. However, if it is not necessary to use a different body, Since the structure of the electric wire can be easily removed by the member, the holding force of the electric wire cannot be sufficiently obtained. Therefore, an object of the present invention is to provide a connector which can easily increase the holding force of the electric wire and can reduce the number of parts. Still another object of the invention is to provide an illumination device using the connector. According to an exemplary aspect of the present invention, a connector is provided which is provided with a connection member between a connection wire and a connection object. The connecting member has: a body portion formed in a square tubular shape; and an insertion portion formed in the body One side of the portion for inserting the electric wire; the spring portion disposed on the other side of the main body portion and having a contact portion for connecting the electric wire; and a terminal portion connected to the connection object; the spring portion The first spring portion and the second spring portion are disposed opposite to each other, and the contact portion of at least one of the first spring portion and the second spring portion has a front end portion formed in a tip shape. In an exemplary aspect, an illumination device is provided, comprising: the connector; an electric wire connected to the connector; an LED; and a circuit board on which the LED is mounted; the connector is mounted on the circuit substrate The connector of the exemplary embodiment of the present invention can easily increase the holding force of the electric wire by 201218,561 and can reduce the number of parts. Another exemplary embodiment of the lighting device of the present invention is to mount the LED on one side of the substrate. Easy to assemble. [Embodiment] First, the overall configuration of an illumination device according to one embodiment of the present invention will be described with reference to Figs. 1 and 2 . In the illuminating device 20 of the first and second drawings, a bulb-type electric lamp is fixed, and a heat transfer member 22 having a large plate shape is fixed to one end, that is, the upper end side of the tube heat dissipating member 21, by screws or the like. The heat dissipating member 21 is a die-cast product mainly composed of an excellent metal such as aluminum, and a fin for forming a plurality of heat can be formed on the outer peripheral surface thereof. Each of the heat transfer members 22 is made of gold having excellent heat conductivity such as aluminum. On the upper surface of the heat transfer member 22, a square circuit board 23 is fixed by a plurality of screws 24. One or a plurality of LEDs 25 are mounted on the upper surface of the first main surface of the circuit board 23 and integrated in the central portion thereof. In the up-and-down direction, the first main surface of the circuit board 23 faces the two main surfaces, that is, the lower surface is substantially close to the upper surface of the heat transfer member 22, and the circuit 23 is covered at intervals above the heat transfer member 22 and A dome-shaped outer cover 26 is attached to the LED 25. The cover 26 is made of glass or a transparent, translucent resin or the like. Two connectors 27 having the same configuration as each other are mounted on the upper surface of the circuit board 23. These connectors 27 are electrically connected to the LEDs 25 via circuit conductors (not shown) provided on the surface of the circuit board. From the two entanglements of the shape of the heat, all the large, that is, the number of the first combination. The substrate is connected to the upper portion of the cylindrical heat dissipating member 2 by the power supply wires 28 for supplying power to the LEDs 25, respectively. Each of the power supply wires 28 is made to have a rod-shaped core wire. A component fixing member 29 is provided on the other end of the heat dissipating member 21, that is, on the lower end side. The upper portion of the component fixing member 209 is fitted and fixed to the inner side of the heat radiating member 2 portion. The lower portion of the part fixing member 29 is attached to the outer portion from the heat radiating member 2 1 and is provided with a lamp head 3 在. The two types of power supply are connected to the base 3 i via various components on the inner side of the heat radiating member 2 1 . In this manner, the LEDs 25 can be supplied with power via the lamp head 31, the two power supply wires, the two connectors 27, and the circuit board 23. Referring to Fig. 2 and referring to Figs. 3A to 3C, the description will be made. The connector 27 has a conductive connecting member 32 that is connected to the insulating case 3 3 between the power supply electric wire 28 and the connection object, that is, the circuit board 23, and accommodates the holding connection member 32. The casing 33 is formed with a flat suction surface 34 formed thereon, and a wire insertion portion 36 is formed at 35. The lower surface 3 7 of the housing 3 3 is opened to expose a portion of the connecting member 32. The back surface 38 of the housing 3 3 is open at this point, but can also be closed. The adsorption surface 34 is adapted to adsorb and retain a portion of the connector 27 by means of an adsorption tool of the self-contained device. The electric wire portion 36 has a function of guiding the insertion of the electric power supply wire 28. The connecting member 3 2 will be described with reference to Figs. 2 to 3C and also to Figs. 4A and 4B. 28, This, the member: 1 under the I 28 electrical 28, the connector line, and the front in this case, the insertion of the mover, the needle 201218561 connecting member 3 2 is to cut, bend and tin plate the metal plate The processing and forming body integrally includes: a main body portion 41 formed in a square tubular shape such as a square tubular shape; and an insertion portion 42 formed on one side of the main body portion 41; the first spring portion 43 and the second spring portion 44, which is formed on the other side of the main body portion 41; a first terminal portion 45 and a second terminal portion 4.6 are respectively formed on both end sides of the connecting member 32; and an upper panel portion 48 having a fixing for A fixing portion 47 on the housing 33. The insertion portion 42 is disposed to face the wire insertion portion 36 of the casing 33, and is a portion into which the power supply wire 28 is inserted. The jitter of the power supply wire 28 inserted into the cylindrical body portion 41 by the insertion portion 42 is suppressed. The first spring portion 43 and the second spring portion 44 are disposed to face each other, and the opposite faces are provided with contact portions 43a, 44a for contacting the power supply wires 28, respectively. The first spring portion 43 has greater rigidity and the second spring portion 44 is formed to have less rigidity. Further, the tip end portion of the contact portion of at least one of the first spring portion 43 and the second spring portion 44 is formed in a tip end shape. Here, the front end portion of the contact portion 44a of the second spring portion 44 is formed in a tip shape. Further, the shape shown in the figure is an acute angle, but it may be a right angle as long as the angle of the tip end is formed. The first terminal portion 45 and the second terminal portion 46 are exposed on the lower surface 37 of the casing 33 and are portions soldered to the electric circuit of the circuit board 23. The first terminal portion 45 close to the insertion portion 42 has a shape that is folded back below the body portion 41 so as not to hinder the insertion of the power supply wire 28 toward the insertion portion 42, and is provided to make excess solder during soldering. Escape one or 201218561 multiple gaps 45a. The second terminal portion 46 remote from the insertion portion 42 is divided into a strand and the joint portions 46a, 46b at the two portions can be welded to the circuit board 23. The relationship between the connector 27 and the power supply wire 28 will be described with reference to Figs. 5A to 5C. The state before the power supply wire 28 is attached to the connector 27 is shown in Fig. 5A. When the power supply wire 28 is attached to the connector 27, the single wire portion 28a composed of the conductor of the power supply wire 28 is inserted into the wire insertion portion 36 of the connector 27. At this time, the insertion direction of the power supply wire 28 is substantially parallel to the surface of the circuit board 23 as the connection object. By inserting the power supply wire 28' in a direction parallel to the circuit board 23, the height of the connector 27 from the circuit board 23 can be reduced, so that illumination from the LED 25 can be prevented as much as possible. The state after the power supply wire 28 is attached to the connector 27 is shown in Fig. 5B. When in the state of FIG. 5B, as shown in FIG. 5C, the single wire portion 28 8 of the power supply wire 28 is interposed between the first spring portion 43 and the second spring portion 44 of the connecting member 32. And the second spring portion 44 is mainly elastically bent toward the outside. As a result, the contact portions 43a, 44a are mainly pressed against the circumferential surface of the single wire portion 28a by the elastic restoring force of the second spring portion 44. In this state, since the front end portion of the contact portion 44a is formed in a tip shape, the single wire portion 28 8a can be firmly held to prevent falling off. In this way, an increase in the holding force of the power supply wire 28 can be achieved. Further, it is also possible to use a solder on the stranded wire 201218561 instead of the single wire portion 28 8 a. As described above, the power supply wire 28 can be surely connected to the connector 27 with a simple operation. Therefore, the connector 27 and the LED 25 can be mounted on the circuit board 23 at the same time, and the connection between the connector 27 and the circuit board 23 can be easily performed by solder. Next, referring to Fig. 2 and referring to Figs. 6A to 6C, a connector 2 7 ' as a variation of the connector 27 will be described. The connector 2 factory is made of metal in the same manner as the connecting member 32 of the connector 27 described in the second to fifth embodiments. In other words, the connector 27' is removed from the connector 27 described using the second to fifth embodiments. Therefore, the components having the same functions as those of the connecting member 32 in the connector 2 7 ' are denoted by the same reference numerals, and the description thereof will be omitted, and only the portions having different functions will be described. The metal connector 27' is formed with a flat adsorption surface 49 on the upper surface of the upper panel portion 48. This adsorption surface 49 is also suitable for adsorbing and holding the connector 2 7 ' by an adsorption tool of an automatic mounting device. Thus, the adsorption surface 49 can be directly formed on the metal connector 27'. The relationship between the circuit board 23, the connector 27', and the power supply wire 28 will be described with reference to Figs. 7A to 7C. Fig. 7A shows a state before the power supply wire 28 is mounted on the connector 27' mounted on the circuit board 23. The upper surface of the circuit substrate 2 3 is covered with an insulating film 51. A connector 27' is attached to the electric circuit 52 exposed by partially removing the insulating film 51 by soldering. When the power supply wire 28A-10-201218561 is attached to the connector 27', the single wire portion 28a composed of the conductor of the power supply wire 28 is inserted into the insertion portion 42 of the connector 27' (see Fig. 6A). In this case, the insertion direction of the power supply wire 28 is substantially parallel to the surface of the circuit board 23 as the connection target. The state after the power supply wire 28 is attached to the connector 2 7 ' is shown in Figs. 7B and 7C. In the same manner as the connector 27 described above, the relationship between the power supply wire 28 and the connector 27' in the state shown in Figs. 7B and 7C will be described with reference to Fig. 5C. In Fig. 5C, the single wire portion 28 8 a of the power supply wire 28 is interposed between the first spring portion 43 and the second spring portion 44 of the connecting member 32, and mainly causes the second spring portion 4 4 to face outward. Elastic bending. As a result, the contact portions 4 3 a, 4 4 a are mainly pressed against the circumferential surface of the single-wire portion 28a by the elastic restoring force of the second spring portion 44. In this state, since the front end portion of the contact portion 44a is formed in a pointed shape, the single wire portion 28 8a can be firmly held to prevent falling off. In this way, an increase in the holding force of the power supply wire 28 can be achieved. Further, it is also possible to use a solder wire on a twisted wire instead of the single wire portion 28a. As described above, the power supply wire 28 can be surely connected to the connector 27' with a simple operation. Therefore, the connector 27' and the LED 25 can be mounted on the circuit board 23 at the same time, and the connection of the connector 27' to the circuit board 23 can be simply performed by solder. Further, the present invention is not limited to the above embodiment, and some or all of them may be described in the following attached notes, but are not limited thereto.
