【Example】

 A first embodiment of the present invention will be described below with reference to FIGS.

First, an IC socket using this frame removing jig will be described. Reference numeral 1 denotes a base, which is formed of an insulating material in a substantially quadrilateral shape, and has a number of recesses 1a for press-fitting and fixing connection terminals 2 to be described later, respectively, on two sides thereof. Further, a pair of protrusions 1b are respectively provided on the remaining two side surfaces where the recess 1a is not formed, and protrusions 1c for positioning the frame 4 to be described later are respectively provided at positions corresponding to the protrusions 1b. Further, projecting walls 1d having a substantially L-shaped horizontal section for positioning the IC5 are projectingly provided at four corners of the base 1, respectively.

Reference numeral 2 denotes a connection terminal, which is composed of a contact piece 2a and a terminal piece 2b made of a conductive material having a spring property. The contact piece 2a and the terminal piece 2b are formed by integrally connecting the base end portions so that the tip end portion of the contact piece 2a is shorter than the terminal piece 2b and spreads out in a substantially V shape. The base ends are press-fitted and fixed in the respective recesses 1a of the base 1 and are arranged in rows on two opposite side surfaces of the base 1.

Reference numeral 3 denotes a holding metal fitting, which is made of a sheet metal material and is formed of a holding piece 3a and a pair of leg pieces 3b which are bent and bent at right angles from the vicinity of the central portion between both ends of the holding piece 3a. .. A burring coupling hole 3c is formed in the center of the leg piece 3b so as to project to the holding piece 3a side. On the other hand, as shown in FIG. 5, on the back surface of each projecting piece 1b of the base 1, there is formed a coupling recess in which a boss 1e is projectingly provided at the center thereof, and two holding metal fittings 3 are provided. When the boss 1e is press-fitted into the coupling hole 3c of the leg piece 3b to be joined to the base 1, the holding pieces 3a are not formed with the recess 1a of the base 1 as shown in FIG. The other two side surfaces are opposed to each other with a distance L. Further, guide pieces 3d that are inclined in the opposite direction to the leg pieces 3b are formed at both ends of the holding piece 3a.

Then, the base 1 is fixed by surface-mounting the terminal piece 2b of the connection terminal 2 and the leg piece 3b of the holding metal fitting 3 on the circuit board surface P by solder connection.

Reference numeral 4 denotes a frame, which is made of an insulating material and is formed in a quadrilateral frame shape with the opposing two-sided frames 4a and 4a and the remaining two-sided frames 4b and 4b. A groove 4c is provided in the center of the inside of the two-sided frames 4b, 4b, and a taper surface 4e is provided in approximately the upper half and an engaging projection 4d is provided in the approximately lower half at both outer ends. ..

When the IC5 is mounted on the base 1 with its four corners positioned on the projecting walls 1d provided at the four corners of the base 1, the leads 5a projecting from the two side surfaces of the IC5 are connected to the connecting terminals 2. When the frame 4 is placed on the contact pieces 2a, and then the frame 4 is fitted onto the base 1 by positioning the groove 4c on the protrusion 1c of the base 1 so as to surround the IC 5, the frame 4 is inserted. 4, the engaging protrusions 4d are guided by guide pieces 3d provided at both ends of the holding piece 3a of the holding metal fitting 3 and are engaged with the lower sides of both ends of the holding piece 3a while pushing the both ends of the holding piece 3a to the outside. And each lead 5a of the IC5 is sandwiched between the contact piece 2a by the two side frames 4a, 4a. At this time, the contact piece 2a having a spring property is bent and each lead 5a is elastically contacted and connected to the contact piece 2a with a predetermined contact pressure.

By the way, the frame removing jig 6 shown in FIG. 1 is used when the IC 5 mounted as described above is removed from the IC socket.

The frame removing jig 6 is formed of a metal or an insulating material in a flat plate shape, and the removing portion 61 of the frame 4 is provided at one end thereof, and the gauge portion 62 and the adjusting portion 63 are provided at the other end thereof. It is provided integrally.

The removal part 61 is composed of bifurcated claws 61a, 61a having a tapered tip part, and these claws 61a, 61a are respectively formed on both tapered surfaces 4e, 4e provided at both ends of the frame 4b of the frame 4. The pitch and size are such that they can be inserted at the same time. Therefore, as shown in FIG. 5, by inserting the pawls 61a into the tapered surfaces 4e, 4e of the frame 4 and tilting them in the outward direction indicated by the arrow, both ends of the holding piece 3a are moved outward as indicated by the alternate long and short dash line. The IC 5 can be removed from the IC socket together with the frame 4 by disengaging the engaging projection 4d of the frame 4 that has been moved and held in the lower side.

In the gauge portion 62, the outer transfer dimension W ₁ is the maximum allowable dimension Lmax of the distance L between the opposing holding pieces 3a shown in FIG. 6, that is, the engaging projections 4d of the frame 4 are at both ends of the holding piece 3a. The distances L are set to be equal to the minimum distance L required for securely engaging and holding the lower sides without any trouble. Then, as described above, when the frame 4 is detached from the holding piece 3a by the detaching portion 61, the distance L between the opposing holding pieces 3a may be plastically deformed to be large. When the outside of the gauge portion 62 is put between the holding pieces 3a and checked, the distance L 1 needs to be reduced if the outside fits between the holding pieces 3a.

The adjusting portion 63 is formed in the center of the gauge portion 62 with a slit 63a having a groove width W ₂ slightly larger than the plate thickness dimension of the holding piece 3a of the holding metal fitting 3. Therefore, as described above, when it is necessary to reduce the distance L, the distance L is adjusted by inserting the end portion of the holding piece 3a into the slit 63a and deforming it.

In the frame removing jig 6 for such an IC socket, the distance L between the removing portion 61 for removing the engaging frame 4 from the holding piece 3a and the opposing holding pieces 3a after the removal is set. Since the gauge portion 62 for checking and the adjusting portion 63 for adjusting the distance L are integrally provided, the frame 4 engaged with the detaching portion 61 is detached from the holding piece 3a, and immediately thereafter, integrally provided. While checking the degree of deformation of the holding piece 3a by applying it between the holding pieces 3a after removing the gauge portion 62, the adjusting portion 63 appropriately deforms the holding piece 3a to adjust the distance between the holding pieces 3a. The same jig can be easily used to make it appropriate.

Next, a second embodiment will be described with reference to FIG. This is different from the first embodiment only in the gauge portion 62, but the other configurations are the same.

In the first embodiment, when the distance L between the opposing holding pieces 3a is reduced by the adjusting portion 63, on the contrary, the distance L becomes too small, so that the engaging projection 4d of the frame 4 is held by the holding piece 3a. It is preferable that the distance L is set to an allowable minimum dimension, that is, Lmin or more so as not to be guided by the guide pieces 3d provided at both ends. Therefore, in the configuration of the gauge portion 62 of the present embodiment, the two slits 62a are provided on both sides of the slit 63a of the adjusting portion 63 so that the outer dimension W ₁ is Lmax and the inner dimension W is Wmax. ₃ is set to be equal to Lmin, respectively. Then, when the gauge portion 62 is put between the two holding pieces 3a and checked, if the both holding pieces 3a are fitted between the two slits 62a, the distance L is between Lmin and Lmax and the adjusting portion 63 is used. It is not necessary to adjust, and if both holding pieces 3a are outside or inside of the two slits 62a, the adjusting portion 63 may adjust the distance L to be small or large.

In each of the first and second embodiments, the frame removing jig 6 integrally includes the removing portion 61, the gauge portion 62, and the adjusting portion 63. When adjusting the distance L between 3a without using the adjusting part 63, for example, by hand, use the removing part 61 and the gauge part 62 integrally without providing the adjusting part 63. Good.
