Embodiments of the present invention will be described below.
Embodiment 1 of the Invention
1 to 6 show a first embodiment of the present invention.

  First, the configuration will be described. Reference numeral 11 in FIG. 1 denotes an IC socket as a “socket for electrical parts”. This IC socket 11 is a wiring board that is a “second electrical part” as shown in FIG. In order to perform a burn-in test or the like of the IC package 12 that is the “first electrical component”, the spherical terminal 12a as the “terminal” of the IC package 12 and its wiring are arranged on the P. The electrical connection with the substrate P is intended.

  As shown in FIGS. 1 and 2, the IC socket 11 has a socket main body 14 that accommodates an IC package 12 and is disposed on a wiring board P. The socket main body 14 has an upper side. A plate 15 and a lower plate 16 are provided. Here, the upper plate 15 and the lower plate 16 are fixed to each other by, for example, bolt-nut connection. The upper plate 15 is formed with a plurality of substantially cylindrical insertion holes 15a having step portions 15b penetrating in the vertical direction. On the other hand, the lower plate 16 is formed with a large number of substantially cylindrical insertion holes 16a having stepped portions 16b penetrating in the vertical direction. In the socket body 14, a large number of so-called one-end sliding type contact pins 21 are arranged in the insertion holes 15 a of the upper plate 15 and the insertion holes 16 a of the lower plate 16 so as to be movable up and down.

  As shown in FIG. 3, the contact pin 21 is provided on a substantially cylindrical barrel 25 and one end 25 a of the barrel 25 (upper side in FIG. 3), and contacts the spherical terminal 12 a of the IC package 12. A substantially rod-shaped “first contact member” having a first contact portion 22 a that is electrically connected to the crown 22 and the other end portion 25 b of the barrel 25 (lower side in FIG. 3) A plunger 23 as a substantially rod-shaped “second contact member” having a second contact portion 23 a that is electrically connected to the base 22 and the barrel 22 and the plunger 23 are disposed in opposite directions. And a coil spring 24 as “biasing means” for urging the spring.

  Here, as shown in FIG. 4, the barrel 25 is formed by bending (curling) a plate material into a cylindrical shape, and has a seam 25f. As shown in FIG. 3, a locking portion 22 b having a convex shape is formed on the outer peripheral portion of the crown 22, and a concave shape is formed on the inner peripheral portion in the vicinity of the end portion 25 a of the barrel 25. A groove-like locked portion 25c is formed, and the locking portion 22b can be locked to the locked portion 25c. That is, the crown 22 is inserted into the barrel 25 from the end 25a of the barrel 25 while opening the joint 25f, and when the locking portion 22b reaches the locked portion 25c, the crown 25 is elastically reduced in diameter. The locking portion 22b is locked to the locked portion 25c and the locked state of both is maintained.

  Further, as shown in FIG. 3, the end 25a of the barrel 25 is formed thin so that the outer side is recessed. Further, as shown in FIG. 1, a stopper 25 e is formed on the outer peripheral portion of the barrel 25 to contact the step portion 15 b of the upper plate 15 and restrict the upward movement of the barrel 25.

  Further, as shown in FIG. 3, the plunger 23 has a base 23 b having a diameter larger than that of the second contact portion 23 a, and a truncated cone-shaped tapered portion 25 d is formed at the end 25 b of the barrel 25. The base 23b of the plunger 23 comes into contact with the tapered portion 25d of the barrel 25 from the inside so that the downward movement of the plunger 23 is restricted.

  Next, a method for manufacturing the contact pin 21 will be described.

  As a first manufacturing method of the contact pin 21, there is a method described below. This method is a method of fitting the crown 22 to the end portion 25 a of the barrel 25 after inserting the plunger 23 into the barrel 25 in the assembly process.

  First, in the barrel forming process, portions corresponding to the locked portion 25c, the tapered portion 25d, and the stopper 25e are provided on one side of the plate material by pressing or the like, and then the plate material is bent so that the one side is on the inside. The barrel 25 is formed by processing and forming into a cylindrical shape to form a locked portion 25c, a tapered portion 25d, and a stopper 25e.

  After that, the assembly process is started, the barrel 25 is supported with its end portion 25a facing up, and the crown 22 is dropped into the upper end portion 25a of the barrel 25 and inserted to lock the barrel 25. The part 22b is locked to the locked part 25c.

  Specifically, as shown in FIG. 5A, the barrel 25 is installed on the first punch 26. At this time, the barrel 25 is arranged such that one end 25a is positioned above and the other end 25b is positioned below. Then, the plunger 23 and the coil spring 24 are sequentially inserted into the barrel 25 from the end 25 a of the barrel 25. At this time, the plunger 23 is arranged such that the base portion 23b is located above and the second contact portion 23a is located below. Further, the crown 22 is attracted to the second punch 27 located above the first punch 26. At this time, the crown 22 is arranged such that the first contact portion 22a is positioned above and the locking portion 22b is positioned below.

  Next, the second punch 27 is moved downward together with the crown 22, that is, toward the first punch 26. Then, the crown 22 comes into contact with the end portion 25a of the barrel 25 and descends while opening the joint 25f (see FIG. 4). When the locking portion 22b reaches the locked portion 25c, as shown in FIG. 5B, the seam 25f is closed, the locking portion 22b is locked to the locked portion 25c, and the crown 22 is The end portion 25a of the barrel 25 is fitted.

  Here, since the contact pin 21 is completed, when the contact pin 21 is removed from the first punch 26 and the second punch 27, the manufacture of the contact pin 21 is completed.

  As described above, the barrel 25 is formed by bending a plate material into a cylindrical shape, and the crown 22 is merely fitted to the end portion 25a of the barrel 25 by utilizing the characteristic that the joint 25f is opened. Thus, the locking portion 22b and the locked portion 25c can be locked to each other. Therefore, unlike the conventional method, an operation of crushing a part of the barrel 25 with a needle for locking the locking portion 22b and the locked portion 25c becomes unnecessary. As a result, the manufacturing cost of the contact pin 21 can be reduced, and it is possible to easily cope with the diameter reduction of the contact pin 21 toward a narrow pitch.

  Further, when the locked portion 25c, the tapered portion 25d, and the stopper 25e of the barrel 25 are formed, as described above, in the barrel forming step, the portions corresponding to the locked portion 25c, the tapered portion 25d, and the stopper 25e. Can be processed and formed in the state of a plate material. Therefore, compared with the case where the barrel 25 is manufactured by cutting, the forming operation of the locked portion 25c, the tapered portion 25d, and the stopper 25e can be performed very easily and quickly. The manufacturing cost of the pin 21 can be reduced.

  Furthermore, in the assembling process, as described above, the barrel 25 is supported with its end 25a facing upward, and the crown 22 is dropped into the upper end 25a of the barrel 25 and inserted. Since the locking portion 22b is locked to the locked portion 25c, the parts of the contact pin 21 (barrel 25, crown 22, plunger 23 and coil spring 24) are arranged horizontally, unlike the conventional method. There is no need to do it. As a result, the manufacturing cost of the contact pin 21 can be further reduced.

  Further, as a second manufacturing method of the contact pin 21, there is a method described below. This method is a method in which the plunger 23 and the crown 22 are simultaneously fitted to both end portions 25a and 25b of the barrel 25 in the assembly process.

  First, in the barrel forming step, portions corresponding to the locked portions 25c and the stoppers 25e are provided on one side of the plate material by pressing or the like, and then the plate material is bent so that the one side is on the inner side. By forming the locked portion 25c and the stopper 25e, the barrel 25 in a state in which the tapered portion 25d is missing is formed.

  Thereafter, the assembly process is started, the crown 22 is supported in a state where the first contact portion 22a faces downward, and the barrel 25 is dropped into the upper end portion of the crown 22, that is, the locking portion 22b. By inserting, the locking portion 22b is locked to the locked portion 25c.

  Specifically, as shown in FIG. 6A, the crown 22 is installed on the third punch 28. At this time, the crown 22 is arranged such that the first contact portion 22a is positioned below and the locking portion 22b is positioned above. Next, the barrel 25 is installed above the crown 22. At this time, the barrel 25 is arranged such that one end 25a is positioned below and the other end 25b is positioned above. Further, the coil spring 24 is inserted into the barrel 25 from the upper end portion 25 b of the barrel 25. Further, the plunger 23 is attracted to the fourth punch 29 located above the third punch 28. At this time, the plunger 23 is positioned such that the second contact portion 23a is located above and the base portion 23b is located below.

  Next, the fourth punch 29 is moved downward together with the plunger 23, that is, toward the third punch 28 side. Then, as shown in FIG. 6B, the base portion 23 b of the plunger 23 is inserted into the barrel 25 from the end portion 25 b of the barrel 25. Thereafter, since the barrel 25 is lowered while being pushed by the fourth punch 29, the lower end 25a of the barrel 25 is lowered while the seam 25f is opened by the locking portion 22b of the crown 22 (see FIG. 4). ) When the locked portion 25c reaches the locking portion 22b, as shown in FIG. 6C, the seam 25f is closed, the locking portion 22b is locked to the locked portion 25c, and the crown 22 is The end portion 25a of the barrel 25 is fitted.

  Here, when the end portion 25a of the barrel 25 is opened by the locking portion 22b of the crown 22 to open the joint 25f, the end portion 25a of the barrel 25 expands in a conical shape, and the opening amount of the uppermost portion is maximized. As described above, the end 25a of the barrel 25 is formed in a thin shape with a concave outer side, so that a situation in which the joint 25f does not sufficiently open due to contact with the inner peripheral surface of the third punch 28 is caused. In addition, the end 25a of the barrel 25 can be opened with a relatively small force. As a result, the locking operation between the locking portion 22b and the locked portion 25c can proceed smoothly.

  Further, the downward movement of the fourth punch 29 forms a tapered portion 25d at the upper end portion 25b of the barrel 25 so as to follow the mortar-shaped molding surface 29a of the fourth punch 29. As a result, the base 23b of the plunger 23 is engaged with the end 25b of the barrel 25.

  Here, since the contact pin 21 is completed, when the contact pin 21 is removed from the third punch 28 and the fourth punch 29, the manufacture of the contact pin 21 is completed.

  Also in this case, after inserting the plunger 23 into the barrel 25, the manufacturing cost of the contact pin 21 is reduced for the same reason as when the crown 22 is fitted to the end 25a of the barrel 25 (see FIG. 5). In addition, it is possible to easily cope with a reduction in the diameter of the contact pins 21 toward a narrow pitch.

  In addition, compared to the case where the barrel 25 is manufactured by cutting, the formation of the locked portion 25c, the tapered portion 25d, and the stopper 25e can be performed very easily and quickly. The manufacturing cost of the pin 21 can be reduced.

  Further, in the assembling process, as described above, the crown 22 is supported in a state where the first contact portion 22a faces downward, and the barrel 25 is dropped into the locking portion 22b of the crown 22 and inserted. Therefore, unlike the conventional method, the parts (barrel 25, crown 22, plunger 23 and coil spring 24) of the contact pin 21 are placed horizontally. No need to arrange. As a result, the manufacturing cost of the contact pin 21 can be further reduced.

  In the assembly process, as described above, since the plunger 23 and the crown 22 are simultaneously fitted to the both end portions 25a and 25b of the barrel 25, the manufacturing time of the contact pin 21 can be shortened.

  Next, how to use the IC socket 11 will be described.

  First, the IC socket 11 is disposed on the wiring board P from a state in which the tapered portion 25 d of the barrel 25 of the IC socket 11 is in contact with the stepped portion 16 b of the lower plate 16. Then, as shown in FIG. 1, each contact pin 21 rises while being pushed up by the wiring board P, and after the stopper 25 e of the barrel 25 contacts the step portion 15 b of the upper plate 15, only the plunger 23 is moved. The coil spring 24 rises against the urging force of the coil spring 24, and the second contact portion 23a of the plunger 23 and the wiring board P come into contact with each other with a predetermined contact pressure. On the other hand, the crown 22 of each contact pin 21 protrudes upward from the upper surface 15 c of the upper plate 15.

  Thereafter, the IC package 12 is accommodated on the IC socket 11 and pressed downward. Then, each contact pin 21 descends against the urging force of the coil spring 24 in such a manner that the crown 22 and the barrel 23 are pushed down by the IC package 12, and the first contact of the crown 22 as shown in FIG. The part 22a and the spherical terminal 12a of the IC package 12 are in contact with each other with a predetermined contact pressure. As a result, the wiring board P and the spherical terminal 12a of the IC package 12 are in a state of being electrically connected to each other via the contact pins 21.

In this state, a current is passed through the IC package 12 to perform a burn-in test or the like.
[Embodiment 2 of the Invention]
FIG. 7 shows a second embodiment of the present invention.

  As shown in FIG. 7A, each contact pin 21 of the IC socket 11 according to the second embodiment is engaged with a barrel 25 having a convex shape composed of a plurality of punch holes (two in FIG. 7). As shown in FIG. 7B, when the crown 22 is fitted to the barrel 25, the locking portion 22b is formed. Except for the point that 22b is configured to be locked to the locked portion 25c, it has the same configuration as that of the first embodiment described above.

  In FIG. 7, illustration of the plunger 23 and the coil spring 24 is omitted. Further, the same members as those of the first embodiment are denoted by the same reference numerals and the description thereof is omitted.

  Therefore, the second embodiment has the same effects as the first embodiment described above.

In addition to this, when the contact pin 21 is manufactured, the two parts of the barrel 25 and the crown 22 are preliminarily subjected to predetermined processing (heat treatment such as quenching, plating treatment, etc.), and then these two parts are assembled. Instead, after assembling the two unprocessed parts, the two parts are subjected to a predetermined process, whereby the time required for the predetermined process can be shortened and the manufacturing cost of the contact pin 21 can be further reduced.
