Both ends of the front end of the body portion 41 corresponding to the front end of the press-fit fastening part 44 are formed to be round. This is to prevent interference with the inner surface of the terminal insertion portion 14 when the fixed terminal 40 enters the inside of the terminal insertion portion 14.

A contact portion 46 is formed by extending from the tip of the body portion 41. The contact portion 46 is a portion in contact with the tip of the inclined portion 36 of the movable terminal 30. A swaging portion 47 is formed at the front end surface of the contact portion 46. The swaging portion 47 is a portion which does not interfere with the movable terminal 30 when the fixed terminal 40 is inserted into the terminal insertion portion 14.

A flex prevention bone 48 is provided across the body portion 41 and the contact portion 46. The flex prevention bone 48 serves to prevent flux and solder from being transferred to the contact portion 46 when soldering the RF switch of the present invention to a printed circuit board.

The flex prevention bone 48 is also formed with a long hole 49, the long hole 49 serves to prevent flux and solder from being transferred to the contact portion 46 together with the flex prevention bone 48. . On the other hand, the flex prevention bone 48 is plated to prevent the flex and solder from being transferred to the contact portion 46.

Hereinafter will be described that the RF switch according to the present invention having the configuration as described above is used and assembled.

The RF switch of the present invention is assembled to the housing 10 in the order of the movable terminal 30, the fixed terminal 40 and the outer shell 20. These, the movable terminal 30, the fixed terminal 40 and the outer shell 20 are assembled in an automated device, for example, the movable terminal 30, the fixed terminal 40 and The outer shell 20 is inserted into the corresponding position of the housing 10 while being sucked by the adsorption means.

That is, the movable terminal 30 is inserted into the terminal insertion portion 14 through the first inlet portion 14 ', and the tip bent portion 37 of the movable terminal 30 is inclined downward toward the tip end. The first insertion guide surface 15 of the first inlet portion 14 ′ corresponding thereto is smoothly inserted into the terminal insertion portion 14 by guiding the tip bent portion 37.

When the body portion 31 of the movable terminal 30 is inserted into the terminal inserting portion 14, the length projection 35 of the press-fit hanging portion 34 is pressed into the inner surface of the terminal inserting portion 14. It will be fixed. Insertion of the movable terminal 30 is the connection portion 32 is seated on the edge of the first inlet portion 14 'of the housing 10, the mounting portion 33 is seated in the movable terminal recess groove 16. Proceed until. When the movable terminal 30 is inserted into the terminal inserting portion 14 as described above, the tip of the inclined portion 36 of the movable terminal 30 comes into contact with the ceiling of the terminal inserting portion 14. However, a gap exists between the ceiling of the terminal insertion portion 14 and the tip bent portion 37 due to the presence of the tip bent portion 37 extending from the inclined portion 36.

Next, the fixed terminal 40 is inserted into the terminal insertion portion 14. The fixed terminal 40 is inserted into the terminal insertion portion 14 through the second inlet portion 14 ″. When the fixed terminal 40 is inserted into the second inlet portion 14 ″, the second insertion guide surface ( 15 '), the leading end of the fixed terminal 40 is guided. When the fixed terminal 40 is inserted into the terminal inserting portion 14, the fixed terminal 40 of the fixed terminal 40 is spaced between the front bent portion 37 of the movable terminal 30 and the ceiling of the terminal inserting portion 14. The tip of the contact portion 46 is inserted. At this time, the swaging portion 47 at the tip of the contact portion 46 allows the tip of the contact portion 46 to be more easily inserted between the tip bent portion 37 and the terminal insertion portion 14.

When the pressing protrusion 44 of the fixed terminal 40 is pressed into both wall surfaces of the terminal insertion portion 14 so that the hook protrusion 45 is fixed, the fixed terminal 40 is fixed to the housing 10. do. Of course, the connecting portion 42 and the mounting portion 43 are respectively seated at the edge of the second inlet portion 14 ″ and the fixed terminal recess groove 17 so that the fixed terminal 40 is installed in the housing 10. Set it.

After the installation of the movable terminal 30 and the fixed terminal 40, the outer shell 20 is installed on the outer surface of the housing 10. The outer shell 20 is mounted to the housing 10 with the mounting portion 26 not yet bent. After the outer shell 20 is installed in the housing 10, the mounting portion 26 is bent and seated in the shell recess groove 18 on the bottom surface of the housing 10.

The RF switch of the present invention assembled through such a process is used to be soldered and mounted on a printed circuit board, usually, the tip of the inclined portion 36 of the movable terminal 30 is the contact portion of the fixed terminal 20 ( 46). This state is well illustrated in FIG. 3.

And, as shown in Figure 6 the center terminal 60 through the insertion hole 13 of the housing 10 to the inclined portion 36 of the movable terminal 30 in the terminal insertion portion 14 When pressed, the inclined portion 36 of the movable terminal 30 is pressed and elastically deformed, so that the contact between the tip of the inclined portion 36 and the contact portion 46 of the fixed terminal 40 is disconnected and the electrical connection is broken. Lose. At this time, the swaging portion 37 of the movable terminal 30 provides a relatively large gap between the bottom surface of the terminal inserting portion 14 so that the elastic deformation of the movable terminal 30 is smooth.

The scope of the present invention is not limited to the embodiments described above, but is defined by the claims, and various changes and modifications can be made by those skilled in the art within the scope of the claims. It is self evident.

For example, the swaging portion 47 of the fixed terminal 40 is not necessarily required. This is because even if only the tip bending portion 37 of the movable terminal 30 is sufficiently inserted into the fixed terminal 40. However, if there is up to the swaging portion 47, the insertion of the fixed terminal 40 will be more smoothly.
