[Prior Art] For example, the technique described in Patent Document 1 is known. FIG. 11 is an explanatory view showing a conventional socket device for an electric component described in Patent Document 1. A conventional socket device as shown in Fig. 11 is provided on the printed circuit board 12' and has a plurality of contact terminals 11 on a housing which is formed of a square shape as a whole, that is, on each of the four sides of the frame 10. The electric component 13 mounted in the casing 10 has a 1C circuit built therein, and a groove portion 14 is formed on each of the four side portions. A contact end portion 15 for connection to the above-described contact terminal ^ is formed in each of the groove portions 14. Patent Document 1: Japanese Patent No. 2600816 Recently, it has been desired to further reduce the size of the above-described socket device. For example, it is even desirable to set the casing 1 to a square having a side length of 1 inch or less. In order to achieve such miniaturization, it is considered to reduce the thickness of the casing 1〇. However, once the thickness of the casing 10 is thinned, the top portion Ua of the contact terminal 丨1 shown in FIG. 11 may be easily exposed, and when the electric member 13 is mounted in the casing 1 ,, the electric member 13 is formed. The protruding portion 16 between the groove portions 14 easily interferes with the top portion 11a of the contact terminal 11. Moreover, once such interference occurs, the contact terminal 11 is deformed, and the reliability as a socket device is lowered. 99506.doc 1248713 In addition, in order to avoid the above interference, it is also considered to reduce the width dimension of the contact terminal so that the contact terminal 11 is easily inserted into the groove portion 14 of the electric member 13. However, in the case of such a configuration, the elastic force of the contact terminal 11 is weak, so that the contact pressure with the contact portion 15 of the electric member 13 is reduced, and the reliability of the socket device is lowered depending on the above viewpoint. . SUMMARY OF THE INVENTION The present invention has been made in view of the above-described state of the art, and an object of the present invention is to provide a method of preventing the elastic force of a contact terminal from being weakened, thereby avoiding being located between the groove portions of the electric component in which the contact portion is formed. A protruding portion, a socket device for an electrical component that interferes with the top of the contact terminal. In order to achieve the object, a socket device for an electrical component according to the present invention is characterized by having a casing for mounting an electrical component and a plurality of contact terminals disposed in the casing, the electrical components having respective electrical connections for electrical connection a plurality of groove portions of the contact portion, and a protrusion portion between the groove portions, the plurality of contact terminals respectively connecting the contact portions; and the contact terminal has a top portion and a sagging portion formed on the top portion The hanging portion has a portion that becomes distant from the opposing electrical member when the electric milk member is mounted in the casing. According to the invention thus constituted, since the hanging portion is formed at the top of the contact terminal, the width dimension on the opposite side to the electric member in the vicinity of the top portion can be reduced, so that the vicinity of the top portion can be easily inserted into the groove portion of the electric member, and Since it is not necessary to reduce the width dimension by providing the hanging portion, the strength can be ensured, and the elastic force capable of obtaining a desired contact pressure can be secured. In addition, when the electrical component is mounted in the housing, even if the protrusion 99506.doc 1248713 located between the groove portions comes into contact with the top of the contact terminal, since the protruding portion is guided by the hanging portion of the contact terminal, The electrical components are smoothly mounted in the housing. Therefore, it is possible to avoid the above-mentioned protruding portion of the electric component from interfering with the top portion of the contact terminal. According to the present invention, in addition to the above invention, the present invention is configured such that the hanging portion 0 is formed on both sides in the width direction of the vicinity of the top end of the contact terminal, and electrical is mounted in the casing. In the case of the member, the hanging portions formed on both sides near the top of each of the contact terminals smoothly guide the two protruding portions on both sides of the groove portion of the electric member in which the corresponding contact portion is formed. Further, in the invention, in the above aspect of the invention, the hanging portion is formed by a tapered portion. According to the invention thus constituted, the formation of the hanging portion is easy. That is, while the contact terminal material is punched out from a predetermined plate material, the hanging portion composed of the tapered φ-shaped portion can be easily formed, or can be easily formed by hammering or the like after punching the contact terminal material. a hanging portion formed by a tapered portion. According to the invention of the present invention, in the above aspect of the invention, the installation body is formed of a square, and the plurality of contact terminals are respectively provided on inner walls of the four sides of the casing. According to still another aspect of the invention of the present invention, the width dimension of the top portion of the contact terminal is larger than a width dimension of the groove portion of the electrical component. According to the present invention thus constituted, by widening the width dimension of the top portion, the elastic force of the strong contact terminal can be increased by 99,506.doc, and the desired contact pressure can be easily ensured. Further, according to the invention of the present invention, the length of the hanging portion is substantially equal to the length of the forming portion of the top portion. According to the present invention thus constituted, since the hanging portion is formed to have a sufficiently long length, when the contact terminal is formed by punching a predetermined plate material, a hanging portion that reliably avoids interference with the protruding portion of the electric member can be disposed in the vicinity of the formed top portion. According to the present invention, since the top portion of the contact terminal has a hanging portion, the hanging portion has a portion where the distance from the opposing electric member becomes longer when the electric member is mounted in the casing, and therefore, it is not necessary to reduce the elastic force of the contact terminal. It is possible to avoid the interference between the projections between the grooves of the electrical component in which the contact portions are formed and the top of the contact terminals. Thereby, it is possible to prevent deformation of the contact terminal when the electric component is mounted in the casing, and it is possible to satisfy the demand for miniaturization, and also to secure high reliability as a socket device for an electric component.

As shown in FIGS. 7, 9, and 10, the electric component 3 has, for example, an IC circuit built therein, and has a plurality of groove portions 4 at the lower end portions of the four side portions, and the groove portions 4 are formed to be electrically connected to the plurality of contact terminals 2, respectively. The contact portion 5 is formed with a protruding portion 3a between the groove portions 4. As shown in Figs. 8 to 10, when such an electric component 3 is attached to the casing 1 of the socket device of the present embodiment, each contact portion 5 of the electric component 3 is electrically connected to each of the corresponding contact terminals 2. Thereby, the IC circuit incorporated in the electric component 3 can be electrically connected to the circuit board (not shown) to which the socket device of the present embodiment is mounted via the socket device of the present embodiment. Communication between the circuit boards is possible. In particular, in the present embodiment, since the hanging portion 2e is formed on the side portion of the top portion 2b of the contact terminal 2, the width dimension of the vicinity of the top portion 2b facing the electric member 3 can be shortened, and the vicinity of the top portion 2b can be easily inserted. In the groove portion 4 of the electric component 3, since the hanging portion 2e is provided, it is not necessary to shorten the width dimension, so that strength can be secured, and an elastic force that generates a desired contact pressure can be secured. Further, when the electric component 3 is mounted in the casing 1, even if the contact portion 3a of the electric member 3 comes into contact with the top portion 2b of the contact terminal 2, since the protruding portion 3a is guided by the hanging portion 2e of the contact portion terminal 2, The electric component 3 can be smoothly mounted in the casing 1 in accordance with 99506.doc • 11 · 1248713. Therefore, it is possible to prevent the above-mentioned protruding portion 3a of the electric component 3 from interfering with the top portion 2b of the contact terminal 2. As described above, according to the present embodiment, it is possible to prevent the protruding portion 3a on the electric member 3 from interfering with the top portion 2b of the contact terminal 2 without reducing the elastic force of the contact terminal 2. Thereby, the desired contact pressure can be prevented between the contact portion 5 of the electric component 3 and the contact terminal 2, and the contact terminal 2 when the electric component 3 is mounted in the casing 1 can be prevented from being deformed. The need for miniaturization is satisfied, and high reliability as a socket device for electrical components can be ensured. Further, when the electric component 3 as described above is mounted in the casing 1, the hanging portions 2e formed on both sides in the vicinity of the top portion 2b of the contact terminal 2 can smoothly guide the electric members 3 located in the corresponding contact portions 5, respectively. The two protruding portions 3a on both sides of the groove portion 4 facilitate the attachment work of the electric member 3. Further, since the hanging portion 2e of the contact terminal 2 is formed of a tapered portion, it is easy to form. That is, the contact member material can be formed by punching a predetermined material, and the hanging portion composed of the tapered portion can be easily formed. Alternatively, after punching and processing the contact material, the hanging portion formed by the tapered portion can be easily formed by a hammering process or the like. Further, by widening the width dimension of the top portion 2b of the contact terminal 2, the elastic force of the contact terminal 2 can be enhanced, and the desired contact pressure can be easily ensured. Moreover, since the area of the hanging portion 2e of the contact terminal 2 is set to be sufficiently long, when the contact terminal 2 is punched out from a predetermined plate material, the electric component 3 can be surely prevented from being disposed in the vicinity of the formed top portion 2b.
