Description of the Related Art Conventionally, when mounting an electrical connector on a printed circuit board (hereinafter simply referred to as a board), the electrical connector is sucked and lifted by a vacuum suction nozzle on the apparatus side in a mounting process. 2. Description of the Related Art It has been practiced to move an electric connector to a predetermined position on a substrate and mount the electric connector on the substrate. As one example of such an electrical connector, for example, a suction-compatible connector disclosed in Japanese Utility Model Laid-Open No. 5-31188 is known. In this prior art, a plug connector and a receptacle connector are disclosed. Each connector is provided with a suction assisting tool (suction member), and the suction assisting tool is sucked by a vacuum suction nozzle. Each of these suction assisting tools has a flat suction surface facing upward, and is formed so as to be attached to the fitting opening of the connector or to be cut off integrally with the connector. These suction aids are typically removed with a finger after the connector is soldered to the board. [0003] As disclosed in the above-mentioned prior art, the suction assisting tool is used only when it is attached to a substrate using a suction nozzle. After attaching to, it is removed with fingers. However, since the suction surface of the suction attachment is formed flat so that it can be easily sucked, it is difficult to remove it manually,
There was a problem that workability was poor. [0004] The present invention has been made in view of the above points, and has as its object to provide an IC socket capable of easily removing a suction member after attaching an insulating housing to a substrate. It is. [0005] An IC socket according to the present invention comprises an insulating housing having electrical contacts, and a lever rotatably mounted on the insulating housing, and is mounted on the insulating housing. In an IC socket for electrically connecting or disconnecting an electric contact of an IC package and an electric contact on an insulating housing side by rotating a lever, a suction member for adsorbing a vacuum suction nozzle on an upper surface of the insulating housing. And the suction member has an extension part which is pushed up by a rotation operation of a lever, and the suction member is detached from the insulating housing by displacement of the extension part. . According to the IC socket of the present invention, a suction member for sucking a vacuum suction nozzle is detachably mounted on the upper surface of the insulating housing, and the suction member pivots on the insulating housing. It has an extension that can be pushed up by a pivoting operation of a lever that is attached so that the suction member is detached from the insulating housing by the displacement of the extension, so that the following effects are obtained. That is, after assembling the connector to the board, I
By rotating the lever to mount the C package, the extension of the suction member is lifted by the lever and the suction member is easily detached, so that the removal operation can be omitted and the workability is improved. Preferred embodiments of an IC socket according to the present invention will be described below in detail with reference to the accompanying drawings. FIG. 1 is a plan view of an IC socket of the present invention with a suction member mounted thereon, FIG. 2 is a front view of the IC socket of FIG.
3 shows side views of the IC socket of FIG. 1 as viewed from the lever side. Hereinafter, description will be made with reference to FIGS. The IC socket 1 is a rectangular insulating housing 3 comprising an insulating main body 2 and an upper housing 6 mounted on the upper surface 4 of the main body 2 and configured to slide on the upper surface 4. Having. The IC socket 1 further has a lever 8 for sliding the upper housing 6. The upper housing 6 has a large number of circular through holes 10 (FIG. 1) arranged in a matrix through which pin-like electrical contacts of an IC package (not shown) mounted on the upper housing 6 are inserted. The upper housing 6 has side walls 12 extending along the outside of the main body 2. Each side wall 12 is formed with a plurality of rectangular slots 14 extending along the sliding direction of the upper housing 6, and the slots 14 engage with corresponding projections 16 (FIG. 3) of the main body 2, Upper housing 6
Are attached to the main body 2 so as to be slidable in the vertical direction in FIG. Further, a large number of electric contacts 22 are arranged in the main body 2 corresponding to the above-mentioned through holes 10. Each electric contact 22 has a solder ball 24 at the lower end of each electric contact 22 to be soldered to a substrate (not shown). A plurality of block-shaped protrusions 26, 28, 30 (FIG. 1) are formed at the end of the upper surface 4 of the main body 2, and these protrusions 26, 28, 30 form a lever holding groove 32. ing. On the other hand, as shown in FIG.
The operation portion 8a is disposed on the side wall 12 of the main body 2, the other side is disposed in the lever holding groove 32, and the other side is disposed on the lever 8. Is a support shaft 8b for rotating. A cam shaft 8c in which the support shaft 8a is partially displaced is integrally formed with the support shaft 8b. The cam shaft 8c and the upper housing 6 are engaged with each other, and the rotation operation of the lever 8 is performed. Thus, the upper housing 6 is configured to slide with respect to the main body 2. Since such a method is generally performed conventionally, a detailed description is omitted here. In the center of the upper housing 6, a rectangular opening 3 is provided.
4 (FIG. 1) are formed, and a resin-made suction member 36 is mounted in the rectangular opening 34. That is, the suction member 36 is attached to the upper surface 5 of the insulating housing 3. The suction member 36 will be described with reference to FIG. FIG. 4 is a side view of the suction member 36 used for the IC socket. The suction member 36 has a substantially rectangular flat suction surface 38 on the upper surface side, and the main body 2 on the lower surface side.
Four latch arms 40 (FIG. 4) which are detachably latch-engaged with the openings 34 are protruded. The latch arm 40 is protruded at a position where it engages with the inner edge of the opening 34. The suction member 36 integrally has a tongue piece (extended portion) 42 extending laterally continuously to the suction surface 38. The tongue piece 42 extends to above the operation portion 8a of the lever 8, and when the lever 8 is moved upward, that is, in FIG.
When the tongue piece 42 is rotated in the direction, since the tongue piece 42 is within the rotation locus of the lever 8, the operating portion 8 a of the lever 8 pushes the tongue piece 42 upward. Due to the displacement of the tongue piece 42, the suction member 36 is lifted, the latch engagement is released, and the engagement between the latch arm 40 and the opening 34 is released. This makes it possible to easily remove the suction member 36 by lever operation without removing it using a finger. By this operation, the upper housing 6 moves slightly upward in FIG. 1 and is aligned with the main body 2 such that the electric contacts of the IC package and the electric contacts 22 of the main body 2 are easily connected to each other. The lever operation described above is always performed in preparation for mounting the IC package on the upper surface 5 of the insulating housing 3. Therefore, an operation (step) of removing the tongue piece 42 with a finger from a series of operations for attaching the IC package can be omitted. And lever 8
Is rotated upward substantially perpendicular to the upper surface 4 of the main body 2, and then the IC package is placed on the upper housing 6 from which the suction member 36 has been removed with a low insertion force or zero insertion force. Thereafter, the lever 8 is rotated again to the position shown in FIG.
The electrical contacts of the C package and the electrical contacts 22 of the IC socket 1 are electrically connected. This electrical connection structure using a lever is generally known as an LIF (Low Insertion Force) or a ZIF
(Zero Insertion Force) is well known as a connector, and a detailed description thereof will be omitted. As described above, before the IC package is mounted on the IC socket 1, the IC package can be easily removed by rotating the lever 8 for mounting the IC package. Therefore, it is necessary to intentionally remove the suction member 36 with a finger. And work can be performed efficiently. The engagement between the suction member and the insulating housing may be friction engagement as disclosed in Japanese Utility Model Application Laid-Open No. 5-31188 or adhesion by an adhesive tape in addition to latch engagement. Further, when the tongue piece 42 is disposed at the free end of the operating portion 8a of the lever, the amount of displacement of the tongue piece 42 is increased, and the suction member 36 can be removed at the initial stage of the rotation of the lever 8. . Alternatively, the tongue piece 42 is connected to the support shaft 8 of the lever 8.
When it is arranged at a position closer to b, the force required for removing the tongue piece 42 can be reduced.
